Abstract
The study was aimed at determining the prevalence of gastrointestinal
parasites in AIDS patients with chronic
diarrhoea. This prevalence was compared with that in two
control groups: HIV seronegative diarrhoeal patients and AIDS
patients (HIV seropositive individuals) without diarrhoea.
Stool specimens were screened for parasite infection from
clinically diagnosed hospitalized AIDS patients in seven
hospitals in Addis Ababa. Of 147 AIDS patients with chronic
diarrhoea, 74 (50.3%) were infected with one or more kind of
parasites. Out of the 56 non-AIDS (seronegative) diarrhoeal
patients 23 (41.1%) and out of the 43 non-diarrhoeal
(seropositive) patients 18 (41.9%) were infected by a variety
of intestinal protozoa and helminths. The parasites detected
in AIDS patients only were crptosporidium spp, Isospora spp,
and Blastocystis spp, Ascaris lumbricoides, Giardia lamblia,
strongyloides stercoralis, Taenia saginata, Trichuris
trichura, Entamoeba histolytica, and Hook worm spp. Among
the intestinal parasites, Cryptosporidium spp was exclusively
associated w.i th diarrhoeal AIDS patients (P < 0.001). None of
the other parasites were significantly associated with AIDS
patients. The high proportion of the study subjects who had
diarrhoea in the absence of identifiable parasitic infections
suggests that other infectious agents (eg. Bacteria and
Virus) or mechanisms other than infectious agents are
responsible for the diarrhoea.
