Prevalence of Opportunistic Intestinal Parasites and Associated Factors among HIV Patients while Receiving ART at Arba Minch Hospital in Southern Ethiopia: A Cross-sectional Study

Opportunistic Intestinal Parasites (OIPs) commonly cause morbidity in HIV/AIDS patients due to the decline of CD4 T-cells. The burden of Opportunistic Intestinal Parasitic Infections (OIPIs) in Ethiopia is expected to be high due to poor sanitation and co-pandemicity of HIV/AIDs. Therefore, frequent assessment of the magnitude and associated factors for intestinal parasitosis is essential for the management of HIV/AIDS patients. A hospital based cross-sectional study was conducted among patients attending Arba Minch Hospital Antiretroviral Therapy (ART) Clinic from March to June 2016. Stool specimens were processed for parasitological examination using direct wet mount, formol-ether sedimentation and modified Ziehl-Neelsen staining techniques. CD4+ T-cell count data were taken from patients' medical records. A structured questionnaire was used to collect data on socio-demographic characteristics and possible associated factors for OIPIs. All the data were analyzed using SPSS version 20. Two hundred and twenty ART patients participated in the study. The overall prevalence of intestinal parasitic infections was 28.18% while that of OIPIs alone was 17.72%. Among identified intestinal parasites, Cryptosporidium species accounts for the highest frequency (19/220, 8.63%), followed by Cyclospora species (13/220, 5.90%). Presence of domestic animals (AOR=2.07, 95%CI:1.07-8.40, P= 0.032) and CD4 T-cell count
