Abstract
Background: The merging epidemics of pulmonary tuberculosis (PTB) and diabetes mellitus
(DM) have been raised concerns by many experts but no large scale screening and
intervention have been launched yet, especially in low-income countries like Ethiopia. The
thought that tuberculosis could cause diabetes seems farfetched, but is not. The peculiar
relationship and frequent association of diabetes mellitus and tuberculosis has been observed
for more than 2000 years, yet the reason for this correlation is, to this day, not known.
Objective: the aim of this study was to determine the prevalence of diabetes mellitus among
active PTB patients at St.Peter hospital.
Methods/design: A cross-sectional Hospital based study was carried out and the study
included all active pulmonary tuberculosis patients visiting St. Peter specialized hospital until
the required sample size was obtained. We included 120 active PTB patients: 67 of these were
male and 84 of them were urban dwellers. Analysis of fasting blod glucose was carried out
using venous blood samples by enzymatic colorimetric test for glucose (GOD-PAP Method).
For testing significance, the categorical data were compared using a chi-square test and
expressed as proportion with a 95% confidence interval.
Result: The prevalence of DM was found to be 15.8% (95% CI:9.20-22.45), which was higher
(25.4%) among male than female TB patients(3.8%).Likewise 70% of the patients were from
urban and 30% of them were from rural areas. The prevalence of newly diagnosed diabetic
cases was 84.2% of all patients tested positive for DM. And all of the patients diagnosed as
diabetic were in the age group greater than 25 years of age. The prevalence of IFG was
(26.7%) and that of HIV co-infection in the study population was (52.5%). The occurrence of
DM in HIV co-infection was a little bit higher (15.9%) than HIV negative TB patients
(15.8%). Of all patients with active tuberculosis, 60 (50%) were sputum smear negative. The
proportion of DM was (25%) among smear positive and (6.7%) among smear negative
patients.
Conclusion: The prevalence of diabetes mellitus and pre-diabetes (IFG) among active
pulmonary tuberculosis cases was higher compared to the published prevalence of DM in
Ethiopia. Therefore, it is important to implement a screening program of each TB patient for
diabetes and Vis versa.
