Prevalence, risk factors and impact of cellular immunity on intestinal parasitosis among people living with HIV at Auchi, Edo State, Nigeria.

This study was sought to determine the impact of CD4+ T-cell count and associated risk factors with intestinal parasitosis in people living with HIV (PLHIV) in Central Hospital, Auchi, Edo State, Nigeria. One hundred and seventy (170) HIV-seropositive subjects were enrolled in the study from 24 August 2015 to 22 January 2016. Sociodemographic data were assessed using structured questionnaires. Blood and stool samples were collected from every participant. CD4+ T-cell count and stool parasitology were performed. The prevalence of intestinal parasites was 44.7%. Helminthiasis (67%) was a predominant infection in the study, while 32.9% had protozoasis. Specifically, Ancylostoma duodenale (33.3%) was the most common helminth, and Trichuris trichiura (7.8%), the least. However, Strongyloides stercoralis, Ascaris lumbricoides and Hymenolepis nana were 13.7%, 31.5% and 13.7%, respectively. Cryptosporidium spp. (25.0%) was the only protozoan. Lower CD4+ T-cell count, ART naivety (OR = 2.62 p < 0.05), residence in a rural setting (OR = 0.89, p < 0.05), and farming occupation (OR = 1.70, p < 0.05) were associated with the prevalence of intestinal parasitosis among PLHIV. This study revealed a significantly high prevalence of intestinal parasitosis in ART naive PLHIV with reduced CD4+ count. Hence, it is recommended to frequently test for intestinal parasitosis and commencement of ART in all PLHIV to improve their health and longevity.
