(Addis Abeba University, 2020-05) Kidane, Achenef; Yimer, Getnet (MD, Ph.D.); Yismaw, Gizachew(MSC, Ph.D.)
Interferon-γ release assays (IGRAs) such as QFT gold plus is one of the main tools for the diagnosis of latent TB infection (LTBI). The main objective this study was to assess the effect of Rifapentin and Isoniazid (3HP) on IGRA reversion and conversion. IGRA reversion and conversion rates have generally been reported after preventive TB therapy, but rates vary widely depending on different settings and there was no study conducted in Ethiopia on IGRA reversion and conversion in post 3HP. A retrospective cohort study of 519 human immunodeficiency virus (HIV) positive individuals who had follow up at Zewditu and Alert Hospitals in Addis Ababa, Ethiopia underwent testing with QuantiFERON (QFT) gold plus at enrolment and 12-month follow-up after taking Rifapentine and Isoniazid (3HP) prophylaxis therapy were included in the final analysis in this study to assess the reversion and conversion of IGRA. The rate of IGRA reversion among LTBI positives and the rate of conversion among latent Tuberculosis infection (LTBI) negative at baseline was 67/169 (39.6 %) and 66/350 (18.9 %) respectively. The observed high IGRA conversion rates indicated a higher rate of Mycobacterium TB infection among LTBI negative patients despite taking 3HP. The prevalence of LTBI among HIV positive individuals was found to be 169/519 (32.6 %; 95% CI 28.5% to 36.5%). Having a history of tuberculosis is substantially associated with LTBI (AOR=1.7 [95% CI 1.15, 2.52]). IGRA reversion rate after taking Rifapentin – INH prophylaxis therapy was fairly high and the rate of IGRA conversion was high despite taking the tuberculosis prophylaxis. Hence targeted screening approach for diagnosing latent tuberculosis infection in HIV/AIDS patients using appropriate methods before administration of TB preventive therapy is recommended.
Regulatory System Opportunities and Barriers for Conducting Clinical Trials in Ethiopia: A Descriptive Qualitative Study
(Addis Abeba University, 2020-06) Maru, Mehiret; Woldeamanuel, Yimtubezinash(Dr. ); Makonnen, Eyasu(Prof.)
Introduction: A clinical trial is a research method used to provide evidence on the safety and effectiveness of interventions for specific medical conditions. In contrary to the disease burden, most of the clinical trials were conducted in developed countries and the share of Africa as of 26 June, 2020accounts only around 2.98% of clinical trials done worldwide. Among the 10,249trials conducted in Africa only 1.53% has been done in Ethiopia. Different factors have been identified as a barrier for trial development in Africa and challenges associated with Ethical and regulatory system has been stated as the second most common barrier. The regulatory body is the one who authorizes and inspect clinical trials in Ethiopia. However, no study has been done so far on the opportunities and challenges of clinical trial regulation which affect trial development. Objective: In this study the enablers and barriers of the regulatory system on clinical trial development in Ethiopia is studied. Method: In this descriptive qualitative study, a total of 15 participants, who had experience in conducting clinical trials in Ethiopia and staffs working in Ethiopian Food and Drug Authority(EFDA) clinical trial team were identified from https://ClinicalTrials.gov, http://apps.who.int/trialsearch/default.aspx, from a data obtained from EFDA and by snowball sampling and involved in the study. Then data was analyzed in the thematic way of analysis. Result: The presence of a specific team within EFDA with a guideline, and staffs initiation to regulate clinical trials are mentioned as an opportunity for clinical trial implementation. Different barriers such as lack of human resource and capacity, financial, infrastructure, regulatory guideline and directives, and trial site follow-up inspection are stated as a bottleneck for the researchers to do clinical trial in Ethiopia. Moreover, not having a feedback for reports, not taking part in the trials closeout and unreasonably stringent regulatory system also mentioned as a barrier. Conclusion and recommendation: In Ethiopia, clinical trial researchers face substantial up and downs starting from clinical trial authorization to trial completion. We recommend that there is a need to strengthen the capacity of regulatory body and develop efficient system in order to improve clinical trials regulation in Ethiopia.
Translating animal research into human trials in Ethiopia: Challenges and opportunities
(Addis Abeba University, 2020-06) Abrhaley, Askale; Prof.Giday, Mirutse; Prof. Hailu, Asrat
Background and Objectives: Although the goal of translational research is to bring biomedical knowledge from the laboratory to clinical trial and therapeutic products for improving health, this goal has not been well achieved as often as desired because of many barriers documented in different countries. Therefore, the aim of this study was to investigate the challenges and opportunities of translating animal research into human trials in Ethiopia. Methods: A descriptive qualitative study, using in-depth interviews, was conducted in which preclinical and clinical trial researchers who have been involved in animal research or clinical trials as principal investigator were involved. Data were analyzed using thematic process. Results: Six themes were emerged for challenges: lack of financial and human capacity, inadequate infrastructure, operational obstacles and poor research governance, lack of collaboration, lack of reproducibility of results and prolonged ethical and regulatory approval processes. Furthermore, four themes were synthesized for opportunities: growing infrastructure and resources, improved human capacity and better administrative processes, initiatives for collaboration, and similarities between species. Conclusion and recommendations: The study found that the identified characteristics/features are of high importance either to hurdle or enable the practice of translating animal research into human trials. The study suggests that there should be adequate infrastructure and finance, human capacity building, good research governance, improved ethical and regulatory approval process, multidisciplinary collaboration, and incentives and recognition for researchers to overcome the identified challenges and allow translating of animal research into human trials to proceed more efficiently.
Efficacy and Safety of Combination of Sodium Stibogluconate and Paromomycin for Treatment of Visceral Leishmaniasis and Factors Associated with Poor Treatment Outcomes. A Retrospective Study, North West Ethiopia
(Addis Abeba University, 2020-06) Tamiru, Aschalew; Hailu, Asrat (Prof, BSc, MSc, PHD); Medhin, Girmay (Dr, BSc, MSc, PHD)
Background: Visceral leishmaniasis is among the most neglected tropical infectious disease caused by the protozoan parasite of the genius lesihmania. The incidence of VL is estimated to be 0.2 to 0.4 million cases /year worldwide. It is fatal if left untreated. Objective: The objective of this study was to assess efficacy and safety of combination of SSG (20mg/kg/day) and paromomycin (15mg/kg/day) and associated factors for poor treatment outcomes. Methods: A retrospective cohort study design was used. Medical record review of VL patients treated with combination of sodium stibogluconate and Paromomycin between 2012 and 2019 was conducted. Results: In total, 1000 VL patients were included. The overall initial cure was achieved in 924 (92.4%). Treatment failure, treatment interruptions, default and deaths respectively were noted in 30(3%), 25 (2.5%), 13 (1.3%) and 8(0.8%). The efficacy of SSG/PM (186/208, 89.4%) Vs (738/792, 93.2%) was not different respectively for patients with weight ≤ 42.5kg and >42.5kg (p=0.07). The most common adverse events were raised liver transaminases 351(35.1%), injection site pain 291(29.1%) and increased in serum alpha-amylase 291 (29.1%). The frequency of cardiac arrhythmia 6(0.6%) and clinical pancreatitis 21(2.1%) were low. Factors associated with poor treatment outcomes were sepsis (OR= 7.6, 95% CI: 1.86 - 31.03, P = 0.005), clinical pancreatitis (OR= 4, 95% CI: 1.21 – 13.43, P= 0.02), and cardiac arrhythmia (OR=13, 95% CI: 2.30 – 84.34, P: 0.004). Patients’ body weight had no effect on poor treatment outcome (OR = 1.6, 95% CI: 0.89 – 3.06). Of patients who attended six-month visit, cure was achieved in 259/276 (93.8%). Post kala-azar dermal leishmaniasis was 13 (1.3%). Conclusion and Recommendations. The efficacy of SSG at 20mg/kg with upper maximum dose limit (850mg/day) and PM at 15mg/kg was 92.4%. Our data affirms effectiveness of SSG/PM, as presently used in Eastern African countries, and no issues of concern have been identified. The continued use of the combination therapy is warranted. Similar studies are recommended in the countries affected by the disease. Sepsis, pancreatitis and cardiac arrhythmias should be identified and managed as per VL management protocol to prevent poor treatment outcomes .
Investigating researchers’ perceptions and experiences in conducting clinical trials toward zoonotic diseases in Ethiopia
(Addis Abeba University, 2020-06) Adugna, Senait Belay; Giday, Mirutse (Prof.); Manyazewal, Tsegahun(Dr. )
Background: The emergence and resurgence of zoonotic diseases have continued to be a major threat to global health and the economy. Developing countries are particularly vulnerable due to agricultural expansions and domestication of animals with humans. Scientifically sound clinical trials are important to find better ways to prevent, diagnose, and treat zoonotic diseases, while there is a lack of evidence to inform the clinical trials’ capacity and practice in countries highly affected with the diseases. This study aimed to investigate researchers’ perceptions and experiences in conducting clinical trials towards zoonotic diseases in Ethiopia. Methods: This study employed a descriptive, qualitative study design. It included major academic and research institutions in Ethiopia that had active engagements in veterinary and public health researches. It included the National Veterinary Institute, the National Animal Health Diagnostic and Investigation Center, the College of Veterinary Medicine at Addis Ababa University, the Ethiopian Public Health Institute, the Armauer Hansen Research Institute, and the College of Health Sciences at Addis Ababa University. In-depth interviews were conducted with 14 senior research investigators in the institutions who hold a proven exhibit primarily leading research activities or research units. Data were collected from October 2019 to April 2020. Data analysis was undertaken using open code 4.03 for qualitative data analysis. Results: Five major themes, with 18 sub-themes, emerged from the in-depth interviews in connection with. These were: challenges in the prevention, control, and treatment of zoonotic diseases; One Health approach to mitigate zoonotic diseases; personal and institutional experiences in conducting clinical trials on zoonotic diseases; barriers in conducting clinical trials towards zoonotic diseases; and strategies that promote conducting clinical trials on zoonotic diseases. Conducting clinical trials on zoonotic diseases in Ethiopia is hampered by a lack of clearly articulated ethics and regulatory frameworks, trial experts, financial resources, and good governance. Conclusions: In Ethiopia, conducting clinical trials on zoonotic diseases deserves due attention. Strengthening institutional and human resources capacity is a precondition to harness effective implementation of clinical trials on zoonotic diseases in the country. In Ethiopia where skilled human resource is scarce, One Health approach has the potential to form multidisciplinary teams to systematically improve clinical trials capacity and outcomes in the country.
Bacteriophage to overcome Nosocomial infections associated with multidrug-resistant bacterial pathogens: a systematic review and meta-analysis
(Addis Abeba University, 2020-06) Benson, Ngolobe; Woldeamanuel, Yimtubezinash (MD, M.SC, PhD); Tesfay, Abraham(Dr. )
Background : Antibiotic-resistant pathogens constitute an important and growing threat to public health. The emergence of multidrug-resistant organisms in nosocomial infections is being highly associated with frequent causes of morbidity and mortality in patients. In view of the growing threat of antibiotic resistance, the World Health Organization has warned for a return into a pre-antibiotic era. The antibiotic crisis has rekindled the interest in phage therapy approaches that were developed in Eastern Europe, one of the alternatives recently regaining interest, which was first introduced by Felix d’Herelle at the beginning of the 20th century. Objectives: The main objective of this study was to quantify the pooled therapeutic efficacy and safety status of Bacteriophage for bio-control of nosocomial infections associated with but not limited to multidrugresistant “Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species pathogens” (ESKAPE) bacteria in humans based on available studies. Methods: In this review, the study protocol was submitted for registration in PROSPERO and eligible studies involved prospective interventional studies with patients infected with one or all the six pathogens and who were treated with bacteriophages or a phage cocktail specific to the pathogen, regardless of the year of publication up to December 2019. We searched the PubMed/Medline, Embase and Web of science databases for articles on phage therapy. 14 studies were included in the review with six considered for metaanalysis to quantify the therapeutic efficacy based on available studies on phages that may prevent and eradicate infections associated with but not limited to “Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species pathogens” in humans for control of Nosocomial infections. In addition current gaps in the literature that would prompt further research on bacteriophage in the fight against antibiotic resistance were identified. Results: Phage safety was sufficiently reported in that all studies showed no side effects related to phage administration. A moderate pooled effect size was obtained with a high evidence of heterogeneity (SMD = 0.52, (C.I. = -1.18, 2.22), P< 0.00001, I 2 = 96%). Most studies were pointing towards the overall effect size with one study regarded as an outlier. However, there was no significant treatment difference between the two therapeutic arms as observed in the forest plots. Moreover, the therapeutic efficacy of bacteriophage is inconclusive due to the few available randomized phage studies found with even few sample sizes. Hence more streamlined phage clinical trials with large sample sizes are needed to detect sufficient effect sizes.
Prevalence and Treatment Outcome of Schistosomiasis in Preschool-aged Children; A Systematic Review and Meta-analysis
(Addis Abeba University, 2020-07) Abbay, Mahlet; Medhin, Girmay(Dr. ); Abay, Solomon M(Dr. )
Background: Schistosomiasis is a parasitic disease caused by worms of the genus Schistosoma. Almost 85% of infected individuals live in Africa. Infection among preschool-aged children (1-5 years) in endemic areas was underestimated and is currently excluded from preventive chemotherapy because of limited data on safety and efficacy, and partly due to a common thought that schistosomiasis is not common in preschool-aged children (PSAC). Objective: The aim of this study was to review evidences regarding the prevalence of schistosomiasis and its treatment outcome among preschool aged children. Methods: PRISMA guideline was followed during the conduct and reporting of this systematic review and meta-analysis. A comprehensive search was carried out from PubMed, Cochrane library, Google scholar and HINARI for studies published till April 2020. Extracted data in preliminary table from papers selected for full-text review and passed eligibility criteria. Quality assessment was based on Hoy 2012 tool using 10 criteria addressing internal and external validity. Random-effects model was used to pool measures of effects and to construct 95% confidence interval (CI) around the pooled effect sizes. In addition, subgroup analysis was conducted to improve the outcome. Results: 38 studies were eligible for final systematic review and meta-analysis. Among the total of 19592 children’s participated 18,509 examined and 5,143 were found to be infected with one or more species of schistosomiasis yielding an overall prevalence of 27.7% (95% CI: 22.833.5%). And the result shows there is significant variability between studies (Heterogeneity I =98.252 with Chi-square =2002.59, DF 35 and a P-value < 0.001). The result of meta regression showed diagnosis method used and study year had contributed significantly to the heterogeneity study results. Regarding treatment outcome, the overall CR was 88.9% (95% CI: 83.5-92.7%) and ERR 97.3% (95% CI: 95.4-98.5%). The result of meta regression showed diagnosis method used and study year had contributed significantly to the heterogeneity of study results. Conclusion: this systematic review and meta-analysis showed there was a moderate prevalence of schistosomiasis and also good treatment outcome of praziquantel in preschool-aged children; indicating to review strategies to consider these age groups in mass drug administration deworming programs until proper formulation accessible. 2
Association of Maternal Dietary Pattern and Neural Tube Defects; A Case-control Study in Addis Ababa, Ethiopia
(Addis Abeba University, 2020-07) Mohammedsanni, Afrah; Dr.Medhin, Girmay(MSc, PhD)
Background: Neural Tube Defects (NTDs) are significant public health problems with complex etiology. Maternal nutrition is one of the environmental factors to contribute to the etiology of NTDs. This study aims to assess the relationship of diet with NTDs among pregnant women who received antenatal care services in Zewditu Memorial Hospital. Methods: We conducted a matched case-control study from January 1, 2020 to April 30, 2020 in Zewditu Memorial hospital, Addis Ababa. A total of 252 pregnant women (63 cases and 189 controls) were included in the study. Pregnant women were matched on age, gestational age and gravidity. We used a 70-item food frequency questionnaire to assess the dietary intake of pregnant women. Factor analysis was used to identify major dietary patterns. Cases and controls were confirmed by specialist gynecologists. Conditional logistic regression was used to assess the association between dietary patterns and neural tube defects. Result: We identified seven major dietary patterns using factor analysis: prudent pattern, traditional pattern, western pattern, Mediterranean pattern, raw meat and alcohol pattern, refined cereal and vegetable pattern and sugar and caffeine pattern. In the adjusted model, the odds of having a fetus affected with NTDs was 83% lower among women who had high intake of prudent pattern compared to those who had low intake (high vs. low intake: AOR=0.17; CI: 0.05 - 0.52). Likewise, women with high intakes of Mediterranean pattern scores were less likely to have a fetus affected with NTD (high vs. low intake: AOR=0.20; CI: 0.06 - 0.59). The odds of having NTDaffected fetus was 3 times higher among women with high consumption of traditional pattern scores (high vs. low intake: AOR=3.37; CI: 1.23 - 9.19) compared to those who with low consumption. There was no statistically significant association between western pattern adherence before pregnancy and neural tube defect in the adjusted model (high vs. low intake: AOR=1.40; CI: 0.41 - 4.73) Conclusion and recommendations: This study demonstrated that maternal adherence to high intake of prudent and Mediterranean diets a year before pregnancy have protective effects against NTDs. Conversely, pregnant women with high intake of traditional pattern one year prior to pregnancy are more likely to have a fetus affected with NTDs. Promoting healthy diet prior to pregnancy is one possible way to optimize reproductive outcomes. We suggest the application of dietary patterns as an approach to communicate healthy dietary choices to the public and formulate dietary guidelines.
Azithromycin versus amoxicillin-clavulanate for treatment of otitis media in children: a systematic review and meta-analysis of randomized controlled trials
(Addis Abeba University, 2020-07) Dawit, Gabriel; Makonnen, Eyasu(Prof.); Abay, Solomon M.(PhD)
Background: Otitis media is an ear infection middle that caused by bacteria or a viruses, which affects more children. Amoxicillin/clavulanate is the drug of choice for otitis media currently. However emergency of resistance, long duration of treatment and more adverse reactions make amoxicillin to be a less valuable choice for treating otitis media. Objective: The aim of this study is to compare the efficacy and safety of azithromycin against amoxicillin/clavulanate for the treatment of otitis media in children. Methodology: Two databases PubMed and Cochrane library were searched systematically and from Google scholar manually searched. The articles were screened by two review authors, duplicates were removed by Mendeley reference manager software. Remained search results was screened for fulfillment of PICOs and inclusion criteria. Articles which did not fulfill the PICO and inclusion criteria were excluded from the study. Data extracted by the first review author and checked by second author. For analysis, all the included studies for review are provide on a table with relevant findings. Meta-analysis was performed using STATA software version 16, and Mantel-Haenszel method and effect measure odds ratio was employed for data analysis, data synthesis and creating forest plot. Result: Seven hundred fifty one records were identified and fourteen studies have fulfilled the inclusion criteria. In twelve studies azithromycin had equivalent clinical efficacy and in the remaining two studies the bacteriologic efficacy of azithromycin is lower than amoxicillin/clavulante. Meta-analysis results showed a small statistical difference on efficacy in favor of amoxicillin/clavulanate after completion of treatment and there was no statistical significant difference on efficacy on follow up. There was statistically significant difference of clinical adverse events more in amoxicillin/clavulanate group than in azithromycin. Conclusion: Efficacy of azithromycin is not inferior to amoxicillin/clavulanate to treat otitis media in children, and it is more safe and tolerable in children than amoxicillin/clavulanate. Recommendations: Azithromycin can be a possible first line treatment option of otitis media. More up to date well controlled clinical trial researches are required to replace amoxicillin/clavuluanate.
Efficacy and Safety Profile of Integrase Strand Transfer Inhibitors (InSTIs) for treatment of HIV in Pregnant Women: Systematic Review and Meta-Analysis
(Addis Abeba University, 2020-07) Getachew, Hiwot; Woldeamanuel, Yimtubezinash(Dr. ); Makonnen, Eyasu(Prof.)
Background: Integrase strand transfer inhibitors (InSTIs) are the most recent class of drugs approved on the basis of their efficacy and safety profiles (16). Dolutegravir and elvitegravir are considered US Food and Drug Administration pregnancy category B; while raltegravir belongs to category C. Objective: To assess the efficacy and safety profile of Integrase Strand Transfer Inhibitors drugs for treatment of HIV in Pregnant Women Method: Literature search strategies were done using medical subject headings (MeSH) and text words related to InSTIs drugs and pregnancy. Pubmed, EMBASE, Web of Science, Science Direct, Henari, and the Cochrane Central Register of Controlled Trials and other databases were searched. The estimated effect (Relative Risks) and associated 95% confidence intervals for the reduction of HIV RNA viral load were meta-analyzed using a DerSimonian– Laird randomeffects model (25). Statistical analysis was performed using RevMan 5.3 software. Result: Based on our systematic review and meta-analyses data, treatment with InSTIs based ART regimens showed to be more beneficial for HIV positive pregnant women compared to other currently used treatment strategies. Both preterm delivery and proportion of infants with Small for Gestational Age didn’t show statistically significant association with the use of InSTIs (risk ratio 0.82, 95% CI 0.60–1.13, I 2 =0%) and (risk ratio 0.90, 95% CI 0.58–1.40, I =0%) respectively. DTG based ART showed a lowered maternal serious adverse event compared to current treatment regimen (risk ratio 1.94, 95% CI 1.13–3.32, I 2 =0%). Conclusion: We suggest use of DTG based ART regimen to be preferred first line choice for HIV positive pregnant women, if the pregnancy is confirmed already past 8 weeks of gestation. Although further investigation is necessary about safety data, we suggest InSTI drugs, especially RAL, can be safely used during pregnancy particularly in late presenter pregnant women or as an intensification strategy. Because of the short and long-term consequences of adverse events seen in infants, particularly preterm birth and SGA, future studies need to assess the safety profile of DTG for infants and explore potential mechanisms of adverse outcomes. 2
Metformin-insulin versus metformin-sulfonylurea combination therapies in type 2 diabetes: a comparative study of glycemic control and risk of cardiovascular diseases in Addis Ababa, Ethiopia
(Addis Abeba University, 2020-09) Gebrie, Desye; Makonnen, Eyasu(Prof.); Manyazewal, Tsegahun(Dr. ); Asmamaw, Dawit(Dr.)
Background: The benefits of combination therapies in the management of type 2 diabetes are well-documented, while the comparative glycemic control and cardiovascular outcomes among the different combination options have not been studied well. The study aimed to compare glycemic control and risk of cardiovascular outcomes of metformin-insulin versus metforminsulfonylurea combination therapies in type 2 diabetes mellitus. Method: A comparative cross-sectional study was conducted in five tertiary level hospitals in Addis Ababa, Ethiopia. About 321 patients with type 2 diabetes mellitus who were on continuous treatment follow up on either metformin-insulin or metformin-sulfonylurea combination therapy were enrolled. Participants were interviewed and their medical records were reviewed to investigate medication efficacy, safety, and adherence. The primary outcome measure was glycemic control (reduction in glycated hemoglobin A1c) and the secondary outcome measures were composite cardiovascular outcomes (myocardial infarction, stroke, heart failure), microvascular complications (diabetic neuropathy, retinopathy, and nephropathy), treatment-emergent adverse events, changes in bodyweight, fasting blood sugar, systolic blood pressure, diastolic blood pressure and lipid profiles (low-density lipoprotein-cholesterol, highdensity lipoprotein-cholesterol, and triglycerides). Results: Of the total participants enrolled, 162 (50.5%) were those who received metformininsulin and 159 (49.5%) metformin-sulfonylurea combination therapies for a median of 48 months follow-up. Reduction of HbA1c was not different between the two groups, p = .912, with mean ± SD of -1.04 ± .96 % versus -1.02 ± 1.03%, respectively. Patients who received metformin-sulfonylurea are 4.3 times more likely to have achieved target HbA1c level compared to those who received metformin-insulin, p < .001 (AOR=4.31 [95% CI 1.79-10.32]). Risk of composite cardiovascular outcomes was higher in metformin-insulin group (40.5% versus 34.0%), p = .021. Co-morbidities, body mass index, systolic blood pressure, and HbA1c had a significant association with composite cardiovascular outcomes. Reductions of bodyweight, lipid profiles, and microvascular complications were different between the two groups, p < .05. Conclusion: High proportion of patients who received metformin-sulfonylurea achieved target HbA1c level and had less composite cardiovascular outcomes compared to those who received metformin-insulin. However, these findings have to be confirmed with randomized control trials to determine risks associated with insulin use, while efficacy is maintained as second-line treatment in patients with type 2 diabetes mellitus.
Challenges and prospects of the regional bioequivalence center initiative in Ethiopia: a qualitative study.
(Addis Abeba University, 2020-10) Melesse, Yajeb; Hailu, Asrat (Prof, ); Belete, Anteneh(Dr. )
Background: Evaluation of the interchangeability of multi-source generic drug products or bioequivalence study has become a crucial activity since the share of generic medicines in healthcare has enormously grown over the past few decades. Among four East African Countries, namely, Ethiopia, Kenya, Uganda and Tanzania, there has been an initiative to establish an accessible and affordable BE center for the regional pharmaceutical manufacturers. This study aims at assessing the challenges and prospects of the bioequivalence center initiative in Ethiopia. Methods: In-depth interview was conducted with individuals who were Ethiopian affiliates of the Regional Bioequivalence initiative; local pharmaceutical manufacturers, Ethiopian Food and Drug Administration, Regional Bioequivalence Center and other key stakeholders who are involved in the center capacity building. Data were collected using digital voice recorders, and transcribed. These data were analyzed using an inductive thematic analysis using Nvivo software and the findings were presented in narratives using the respondent‟s own words as illustrations. Results: Based on the findings, four major themes, one as an opportunity and three as challenges, were identified. The mere presence of the Regional Bioequivalence Center by itself was considered as an opportunity by most of the participants. In addition, a number of favorable conditions including awareness and demand for product quality and diversity, the presence of attractive incentive packages for local pharmaceutical manufacturers and the proliferation of the generic medicines market in the region were mentioned as opportunities. On the other hand, lack of resources and stakeholders‟ commitment as well as lack of regulatory enforcement were identified as challenges. Conclusions: The Bioequivalence center initiative has not functioned well as initially planned. The findings of this study suggest the need for government and key stakeholders to actively engage in the program to make the initiative viable. The significance of supporting this initiative could positively contribute to the creation of a competitive local manufacturing sector that will engage in the production of therapeutically interchangeable generic products and ultimately safeguard the health of the society at large.
Eastern Africa Countries Need and Readiness for Implementation of Harmonized Clinical Trials Regulation and National Ethics Review System: A Qualitative Study
(Addis Abeba University, 2020-11) Ejamo, Assefa; Makonnen, Eyasu(Prof.); Woldeamanuel, Yimtubezinash(Dr. )
Background: Medical products are regulated from premarket clinical trials to post marketing surveillance and phase IV clinical trials. Research organizations have responsibilities to conduct clinical trials subject to regulatory and national ethics review process before putting products on the market. Harmonized approaches for regulation of clinical trials and national ethics review are practiced globally including in Eastern Africa countries under regional economic communities. However, there are gaps in medicine regulatory in general and clinical trials regulatory and national ethics review harmonization in particular. Objective: The aim of this study was to assess the need and readiness for implementation of harmonized clinical trial regulation and national ethics review in Eastern Africa. Methodology: A qualitative study was conducted in selected Eastern Africa countries focusing on regional economic communities (RECs). Data were collected through semi structured questionnaire from National Regulatory Authorities, National Ethics Review Committee, development partners, sponsor and research institutions through email by assigning facilitators in each country, and were analyzed thematically using QDA Miner Lite qualitative data analysis software. Specific countries regulatory and ethics review system components were analyzed according to the nature of questions and responses. Results: It was noted that 5 Eastern Africa countries involved (Ethiopia, Kenya, Sudan, Uganda and Tanzania) in the present study had national legislations for medicines and clinical trials regulations. Shortage, lack of experience, lack of appropriate expertise and poor professional mix were staff related problems identified in this study. It was noted that clinical trial structures were established at directorate level in one country, at team level in three countries and none in one. These findings reflect countries readiness for implementation of harmonization initiative. Capacity building, utilizing limited resources in the region and ensuring quality were some of need related findings for implementation of harmonized approach. Existence of platforms like RECs, partners support and enabling conditions were identified opportunities for implementation of harmonized regulation and national ethics review. Challenges identified were lack of awareness, difference in administrative procedures, lack of commitment, resource limitation, and requiring long time for implementation of harmonization. Differences were also noted among countries and RECs (IGAD and EAC) in regulatory system and progress in implementation of harmonization initiative respectively. Conclusion: The readiness of most of the countries in regulating clinical trials is not adequate to implement harmonized clinical trials regulation and national ethics review. However, there is remarkable need for harmonization in the region. Countries need to strengthen their clinical trial regulatory and national ethics review system in consideration of harmonization.
Challenges and strategies for recruitment and retention of participants in clinical trials in Ethiopia: a qualitative study
(Addis Abeba University, 2020-11) Wagaw, Lealem Minwuyelet; Fekadu, Abebawdu (MD, PhD); Makonnen, Eyasu (PhD)
Introduction: Clinical trial is an extensive and demanding process, which takes approximately 10 to 15 years. Clinical trials require the active engagement of human subjects. Recruitment and retention of participants are two major challenges in conducting clinical trials. Poor recruitment and retention of participants in clinical trials can lead to major delays in the development of new products and interventions. This can also cause significant problems in the study validity as they could reduce the statistical power resulting in poor generalizability of the study. Objective: This study is aimed to identify potential challenges and strategies for enhancing recruitment and retention of participants in clinical trials in Ethiopia. Method: A qualitative methodology with a phenomenological approach employed. Semistructured interviews were conducted face to face and through telephone. Interviewees were purposively selected from five candidate study sites which are Armauer Hansen Research Institute, Zewditu Memorial Hospital, University of Gondar, Jimma University, and Addis Ababa University. These sites were chosen primarily because most clinical trials conducted in and potential clinical investigator candidates were employed and affiliated there. Investigators, clinical coordinators, physicians, nurses, and participants involved in clinical trials were the study respondents. The sample size was determined using the criterion of informational redundancy. Of 22 potential respondents approached, 19 consented to the interview. An open-ended topic guide was developed to facilitate in-depth interviews with respondents with sufficient freedom to describe their experiences and perspectives that they deemed relevant to the research questions. Interviews were audio-recorded with consent. Transcriptions were entered into Open Code and coded. Data were analyzed using thematic analysis. Result: Nine of the respondents (47.4%) were females. Respondents were involved as principal investigators (n=5), trial coordinators (n=7), nurses (n=2), physicians (n=2) and trial participants (n=3). Thematic analysis resulted in a generation of 3 main themes and 10 sub-themes. Clinical trial team factors (communication and system-related), participants’ factors (communication and interest related), and study factors (complexity of the study and cost-related) were listed as challenges for recruitment and retention of trial participants. Additionally, four subthemes are mentioned under the three themes as a strategy for recruitment and retention of trial participants, such as promoting clinical trials, improving communication skills, refining the clinical trial setting system, and having a good estimation of cost. Potential challenges and strategies for recruitment and retention of participants in clinical trials were identified under each sub-themes. Poor communication skills, mistreating participants, and lack of knowledge about existing trials are considered to be clinical trial team factors. Also, misconceptions about the trial, low-level education, lack of social support, and participants’ moves around were revealed to be an important challenge among trial participants’ factors. Also study factors such as long questionnaires and assessment, stringent eligibility criteria, frequent appointment, and extra, and inconvenient procedures. However, a wide range of strategies was identified such as increasing awareness, choosing an appropriate trial site, provisions of training, reimbursement and compassionate respectful care, and establishing an efficient tracking system may be the most important interventions to improve recruitment and retention of trial participants. Conclusions: Poor knowledge about research, and complexity of trials were the greatest challenges for low recruitment and retention. Interventions to improve knowledge and provisions of training to the clinical trial team and having compassionate respectful care, providing compensation, increasing awareness in the community are important strategies to consider when designing and planning recruitment and retention plan.
Efficacy and safety of vaccine trials conducted in Africa: a systematic review and Meta-analysis.
(Addis Ababa University, 2021) Tesfai, Sara; Hailu, Asrat; Belete, Anteneh
Background: vaccine preventable diseases have been of global concern. Vaccines are the best way for prevention. Studies are showing that there is disparity in efficacy of vaccines, in industrialized and in low-middle income countries. Additionally, vaccine related diseases aresaid to be occurring in recent decades. Africa produces less than one percent of vaccines and depends on imports. It is important to check how many of these imported vaccines have been subjected to clinical trials, to assess efficacy and safety before they are made available to mass consumption. This study is aimed to evaluate the vaccine trials conducted up to the end of 2020 with no start up period limit to inventory the type of trials undertaken in comparison with the vaccines that are in routine use in African countries and to assess vaccine effectiveness in African settings. Methodology: A systematic review and meta-analysis was carried out to assess the vaccine trials conducted in the 54 African countries. Eighteen WHO approved registries, 2 immunization schedule sites and databases were searched. Data were exported to MS excel and RevMan version 5.4 for analysis. Result: The largest vaccine trial for disease prevention purpose was seen for malaria with 119 (21.2%) whereas the lowest was for tetanus with 1 (0.2%) trial. Out of these vaccines, BCG and OPV are given in all African countries, whereas vaccines for; Hepatitis A Influenza (for both pediatric and adult), MenAC, bOPV, deworming, cholera, DTaP, TdIPV and dtaPHibIP are given only in one country each. From the 26 single disease specific vaccine 17 and from 13 combination vaccines 4 multi-disease vaccines was found to have gone through clinical trial which ranges from the lower 1 ( Tetanus) vaccine trial per disease of interest to the highest of 119 (Malaria) vaccine trials in the single disease specific trials. BCG and OPV given in all African countries (100%) attributed to only 55 (15.5 %) and 2 (0.5%) of the trials, respectively, whereas Malaria vaccine which is given only in 3 (5.5%) of African countries attributed to 119 (33.6%) of the trials. In the malaria vaccine trial review, highest efficacy [30%, 95% CI (0.59, 0.84)] was seen against severe malaria in both children and infants. Whereas, the lowest efficacy [20%, 95% CI (0.75, 0.86)] was found to be in 1st episode of malaria in infants. The highest efficacy [67%, 95% CI (0.16, 0.66)] was seen in HIV positive adults and the lowest efficacy [21%, 95% CI (0.44, 1.42)] was seen in HIV positive infants. The highest efficacy [52%, 95% CI (0.37, 0.61)] of the PCV vaccine was seen against 1st episode of IPD, and the lowest efficacy [13%, 95% CI (0.80, 0.96)] was seen against severe Pneumonia in HIV negative individuals. Conclusion: The overall efficacy of the three types of vaccines that are included in this review was found to be low, and no significant SAEs were found across the vaccines. We found no vaccines terminated for futility. Safety data of these studies were mainly acquired from phase 3 trials not phase 4, we couldn’t assess the safety issues identified from outside of a controlled environment i.e., for a long term effect and the issues seen in general populations.
Self sampling HPV testing as cervical cancer screening approach among women living in low-middle-income -countries: Systematic review and Meta-analysis.
(Addis Abeba University, 2021) Amanuel, Hanna; Dr.W/Amanuel, Yimtubezinash; Prof.Makonnen, Eyasu
Background: More than 85% of cervical cancer deaths occur in low-middle-income countries, and 90% of the mortality burden is primarily attributed to low coverage of cervical cancer screening. Self-sampling HPV could increase the overall cervical screening and contribute to alleviating the burden of cervical cancer in LMICs (low-middle-income countries) Objective: The general objective of this review and meta-analysis was to see if self-sampling HPV screening method can increase uptake of cervical cancer screening in low-middle-income countries. Methods: CENTRAL (Cochrane Central Registry of controlled trials), MEDLINE (through PubMed), Clinicaltrial.gov, WHO Global Health Library, and EMBASE were searched. Reference lists of the relevant studies found were assessed to further search for relevant studies. The MeSH terms for HPV (MeSH (DNA Probes, HPV) (Human Papillomavirus DNA Tests)) and cervical cancer MeSH term (uterine cervical neoplasms) were found and as for the term self-sampling, there was no MeSH term found therefore method of text words/synonyms (Self-sampling, Selfcollection, Self-obtained) for self-sampling was used. For the LMIC, LMIC filter prepared by Cochrane from all LMIC countries listed by World bank was used. Where multiple studies reported the same comparable outcome of interest, we conducted a metaanalysis. Random-effects models was used to generate pooled effect size of relative risk with a 95% confidence interval using RevMan 5.4. Results: Six RCTs (randomized control trials) were included in this review. The studies were from Ethiopia, Kenya, Nigeria, Uganda, Argentina, and Mexico. These studies included a total of 39,274 participants with in the age group ranged from 25 – 65 years. All the studies compared an interventional group of HPV self-sampling method with a control group of a standard of care. HPV self-sampling was reported to be acceptable, and participants stated the device was easy to use and they would use HPV self-sampling instead of the regular hospital screening in the future. There were no adverse events associated with the self-sampling device. In the meta-analysis, uptake of cervical cancer screening services showed that the likelihood of participants to use self-sampling HPV screening method was 75% higher than with standard of care (RR: 1.72, 95% CI 1.58 to 1.87, Isquared: 72%) with insignificant I2, (MODERATE quality of evidence). However, there was no difference between linkage to care between the two groups (RR=1.18, 95% CI 0.77 to 1.81, I2= 87%) (VERY LOW quality of evidence). Conclusion: Self-sampling HPV screening technique has the potential to increase the uptake of cervical cancer screening in LMICs, and is acceptable by women. Moreover, this technique helps overcome many barriers to cervical cancer screening in LMICs such as lack of trained personnel, lack of laboratory supplies, infrastructure, socio-religious and cultural barriers to pelvic examination, limited physical access to patient populations, and the need for spousal permission. As this can reduce social inequalities in access to cervical screening, it helps alleviate the cervical cancer burden in LMICs.
Safety of Equine Tetanus Antitoxin for Prophylactic use In Ethiopia: A Retrospective Multicenter Study
(Addis Ababa University, 2021-04-08) Michele Joseph; Abebaw Fekadu
Tetanus remains an important public health problem in many parts of the world. It is indicated to cause an estimated 56,000 deaths annually worldwide. Among global tetanus deaths, 44% occur in sub-Saharan Africa, and the highest proportion of these occurs in East Africa. In 2017 WHO reported 20 cases of tetanus in Ethiopia. Although tetanus antitoxin (TAT, equine origin) has been replaced by human tetanus immunoglobulin (TIG), it is still in use in developing countries due to the high costs and limited access to TIG. Adverse reactions of TAT have not been studied in Ethiopians. Thus, conducting a Retrospective safety study on TAT in Ethiopia is important to promote public health and support improvement of the product by providing scientific evidence from the local context. Objective: To evaluate the safety of equine tetanus antitoxin when administered to adults under conditions of routine post-exposure prophylactic use in Ethiopia. Methods: A retrospective multicenter study was conducted in Addis Ababa covering three referral teaching public hospitals, (Tikur Anbessa Specialized Teaching Hospital and Zewditu Memorial Teaching Hospital and) and eight public health centers of with high client load for TAT. Charts of patients (n=1213) treated with equine anti toxin for prophylactic use for their wounds from January 2015 to December 2019, older than 18 years of age were reviewed. Results: We included 1213 medical record forms in the final analysis (994 males and 264 females) and the mean age was 29.33 years (SD = 11.41 years). Only 0.98%(12/264) of the females had history of TT vaccination. Among all the charts reviewed head trauma, trauma at workplace and open wound were most frequently seen and only one patient experienced adverse event following immunization. Conclusion and Recommendation: Even though there were major limitation on the data retrieved, on its clarity and completeness, findings from this retrospective study suggests that use of TAT is safe compared to number of injections and the overall disease reported in the country from January 2015 to December 2019. Large study with wider geographical converge will have significance in testing the validity of the current findings.
Comparison of efficacy and safety of dihydroartemisinin- piperaquine versus artemether-lumefantrine for the treatment of uncomplicated falciparum malaria in African children: Systematic review and metaanalysis of randomized control trials
(Addis Abeba University, 2021-06) Assefa, Dawit Getachew; Prof.Makonnen, Eyasu; Dr.Yismaw, Gizachew
Background: Emergence of Plasmodium falciparum resistance to artemisinin and its derivatives poses a threat to global effort in controlling malaria. Resistance has already emerged to most antimalarial drugs in common use. While the concern on resistance in South East Asia but with potential benefits of DHA-PQ over other ACTs, it is necessary to assess if the antimalarial treatment efficacy of this regimen in Africa has changed. The aim of this review was, therefore, to compare the efficacy and safety of dihydroartemisinin-piperaquine and artemether-lumefantrine for treatment of uncomplicated P.falciparum malaria in African children. Method: An electronic systematic search method was used to search for articles from online databases PubMed/ MEDLINE, Embase, and Cochrane Center for Clinical Trial database (CENTRAL) for repossessing randomized control trials comparing efficacy and safety of DHA-PQ and AL for management of uncomplicated Plasmodium falciparum malaria in African children. The search was done from August 2020 to 30 April 2021. Using Rev-Man software (V5.4), R-studio, and Comprehensive Meta-analysis software, the data obtained from the included studies were assembled as risk ratio (RR), MD, and SMD with 95% confidence interval (CI). The per-protocol analysis was used. Result: In this review, 25 studies which involved a total of 13,198 participants were included. PCR unadjusted treatment failure in children aged between 6 months to 15 years was significantly lower in DHA-PQ treatment arm on day 28 than that of AL (RR 0.14, 95% CI 0.08 to 0.26; participants = 1302; studies = 4; I 2 = 0%, high quality of evidence). Consistently, the risk of treatment failure adjusted by PCR was significantly lower with DHA-PQ treatment group on day 28 (RR 0.45, 95% CI 0.29 to 0.68; participants = 8508; studies = 16; I 2 = 51%, high quality of evidence) and on day 42 (RR 0.60, 95% CI 0.47 to 0.78; participants = 5959; studies = 17; I 2 = 0%, high quality of evidence). However, the efficacy was ≥95% in both treatment groups on day 28. On days 28 and 42, a significant increase in serum hemoglobin level from the baseline was also observed in DHA-PQ treatment arm (SMD 0.15, 95% CI 0.05 to 0.26; participants = 2715; studies = 4; I = 32%, high quality of evidence) and (MD 0.35, 95% CI 0.12 to 0.59; participants = 1434; studies = 3; I 2 = 35%, high quality of evidence), respectively. However, DHA-PQ was somewhat coupled with a higher incidence of early vomiting (RR 2.26, 95% CI 1.46 to 3.50; participants = 7796; studies = 10; I 2 = 0%, high quality of evidence), vomiting (RR 1.02, 95% CI 0.87 to 1.19; participants = 8789; studies = 13; I 2 = 20%, high quality of evidence), cough (RR 1.06, 95% CI 1.01 to 1.11; participants = 8013; studies = 13; I 2 = 0%, high quality ofevidence), and diarrhea (RR 1.16, 95% CI 1.03 to 1.31; participants = 6841; studies = 11; I = 8%, high quality of evidence) were more frequent in DHA-PQ treatment arm. Conclusion: From this review, it can be concluded that DHA-PQ reduces recurrent infection and recrudescence with significant impact on hemoglobin recovery more than AL, and bothdrugs are well tolerated. DHA-PQ may, therefore be recommended as an alternative first linetreatment for uncomplicated falciparum malaria in Africa, while use of AL continues.

(Addis Ababa University, 2021-06) Mose, Olyad; Medhin, Girmay (MSc., PhD ); Fekadu, Abebaw (MD, MSc, PhD, MRCPsych); Assefa, Mathewos(MD,Consultant Oncologist)
Background: Worldwide, cancer of the cervix is one of the most common causes of cancer mortality among women, with about 288,000 deaths each year. While it is the second leading cause of cancer mortality among adult women globally, it is the most common cause of mortality in the economically emerging countries including in sub-Saharan Africa. The reason for this high mortality is likely to be the poor access to early detection or screening and treatment services. There is no sufficient Published data on the treatment outcome of cervical cancer in Ethiopia. This study would contribute to the evidence regarding the treatment outcome of cervical cancer. Objectives: To assess the five-year survival among women who attended for treatment of cervical cancer. Methods: A hospital based retrospective cohort study was conducted at the Oncology Department of Tikur Anbessa Specialized Hospital (TASH). Records of patients with a first diagnosis of cervical cancer were selected from a two-year medical records of cervical cancer patients who attended the oncology department of TASH from September 11/2012 to September 11/2014GC.Survival Outcome was evaluated over the subsequent five-year period until 2014GC. Because of the practical challenges of determining actual survival status, continuation in follow up (vs dropout from follow up) was used as a proxy indicator of survival. Descriptive statistics was employed to summarize basic socio-demographic and clinical variables. KaplanMeier and Cox-regression analysis was used to evaluate the potential role of various treatment modalities on survival outcome. Crude and adjusted Hazard ratios with 95% Confidence intervals were presented as measure of association. Statistical tests resulting in a p-value of less than 0.05 were considered statistically significant. Results: Among 1008 cancer patients who were diagnosed and started Treatment at Tikur Anbessa Specialized Hospital Oncology Center during the two-year selection period ,418 had cervical cancer and were included in the current study. At the end of the five-year only 9.9% (40) had survived in follow-up. For the majority, stage at presentation was late. Patients who arrived with later stages (Stage-III) cervical cancer had lower follow-up survival probabilities compared with earlier stage [stage-0, (Carcinoma in situ)] [Adjusted Hazard Ratio=2.17; 95% -CI= 1.40,3.40]. Those who had received combination therapy (Radiotherapy, chemotherapy and surgery) have better survival probability than those who were treated with Radiotherapy and Chemotherapy alone [Adjusted HR= (0.29, 95%CI, 0.84, 2.20), (2.52,95%-CI,1.80,3.40), and (2.02,95%-CI,1.10,3.80)] respectively. Conclusion and recommendation: The clinical factors identified as factors for survival in follow-up (e.g., stage at presentation) appear to justify using survival in follow-up as a proxy measure of survival. However, this is extremely crude proxy. Thus, well planned prospective study of survival is needed. Nevertheless, if the crude assumption is correct, ensuring access to early diagnosis, and treatment is an urgent priority for improving survival of patient with cervical cancer in Ethiopia. There is a need of creating awareness, primary prevention by vaccination, and increasing early detection programs to increase early stages at presentation which gives more opportunity to appropriate treatment. Furthermore, expanding more treatment centers and implementation of advanced Technology like Linear accelerator, rachytherapy and PET-scan needs urgent attention.

(Addis Abeba University, 2021-06) Haile, Dagmawi Chilot; Dr.Manyazewal, Tsegahun(PhD ); Dr. Woldeamanuel, Yimtubezinash(MD, PhD)
Background:Coronavirus disease 2019 (COVID-19) pandemic has infected 173,674,509 people globally resulting in 3,744,408 deaths as of 09 June 2021.Ethiopia is categorized under COVID19 epidemic phase III (advancing outbreak). There are global concerns and predictions that COVID-19 would severely affect tuberculosis (TB) and HIV care and treatment services in resource-constrained countries. Objective: To assess the real-time impact of COVID-19 on TB and HIV care and treatment services in Addis Ababa, Ethiopia. Methods: This was a facility-based, multicentre, cross-sectional study in 10 health centers with high TB/HIV patients in Addis Ababa, Ethiopia. Participants were patients with TB and/or HIV who have been attending TB and/or HIV clinical care and treatment in the study sites in the COVID-19 pandemic period. Data were collected using adapted, interviewer-based questionnaires to investigate the impact of COVID-19 in their routine care and treatment services. Data were entered into Epi Info version 7 and exported to SPSS version 26 for analysis. Variables with a P-value ≤ 0.25 in the bivariate analysis were included in the multivariate logistic regression. Statistical significance was declared if P-value < 0.05. Results: The study included a total of 424 informed and consented participants.Study participants who missed appointments for medication refill were 98 (23.1%).When the effects of other independent variables on appointments/visits for refill were controlled,the following characteristics were found to be the most important pridictors of missed appointments (P < 0.05):age ≥55 [AOR=13.74, 95% CI (4.331-436.428)], monthly income 3001-10000 [AOR=0.05, 95% CI (0.003-0.803)], fear of COVID-19 [AOR=59.14, 95% CI (3.804-9195.85)], transport disruption [AOR=56.91, 95% CI (1.930-16781.4)], reduced income for traveling to health facility [AOR=12.52, 95% CI (19.115-8194.9)],contacting healthcare providers quickly[AOR=0.11, 95% CI (0.017-0.742)], soap availability [AOR=0.01, 95% CI (0.0000.845)], pharmacy accessibility, [AOR=0.01, 95% CI (0.000-0.611)], shortage of some medications [AOR=10.72, 95% CI (1.033-111.290)], and tremendous shortage of non-medical support [AOR=15.30, 95% CI (1.075-218.039)]. The participants were well aware of the COVID-19 preventive measures. According to the participants, the most effective COVID-19 preventive measures were use of facemask (88.4%), frequent handwashing with soap (81.4%), and staying at home (76.4%). The most costly COVID-19 preventive measures that cause financial burden to the patients were costs for buying facemasks [242 (57.1%)], soaps for handwashing [97 (22.9%)], and disinfectants [223 (52.6%)]. Participants responded that the healthcare providers were polite and respectful (99.5%), and willing to listen and answer their questions (99.5%) and give attention to their individual needs (98.6%). Participants who missed follow-up dignositic tests were 97 (22.9%). Variables which were found to be statisticaly significant included the following: age ≥55 [AOR=0.14, 95% CI (0.021-0.909)], denied helth services [AOR=0.20, 95% CI (0.054-0.729)], reduced income for traveling to health facility [AOR=0.06, 95% CI (0.008-0.408)], much harder non medical support [AOR=0.02, 95% CI (0.001-0.404)]. Participants who missed counseling services were 92 (21.7%). In multivariate logistic regression, the following were statisticaly significant: age ≥55 [AOR= 0.11,95% CI (0.016-0.733)], denied health services [AOR= 0.25, 95% CI (0.078-0.787)], fear of COVID-19 [AOR= 0.02, 95% CI (0.001-0.396)],reduced income [AOR= 0.04, 95% CI (0.005-0.333)], availability of soap [AOR= 22.65, 95%CI (1.302-393.974)], availability of sanitizer [AOR= 3.87, 95% CI (1.069-14.041)], slightly shortage of medicines [AOR= 0.26, 95% CI (0.081-0.846)]. Conclusion: COVID-19 pandemic impacted the care and treatment services of patients with HIV and TB negatively. The impact was primarily on their appointments for scheduled medication refills, clinical and laboratory follow-ups. The impact could be mitigated by providing education to the public, compensating travel expenses for eligible patients and their healthcare providers, continuing delivery of TB/HIV care and treatment services.
