Socio-Behavioral Risk Factors Associated with Cryptosporidiosis in HIV/AIDS Patients Visiting the HIV Referral Clinic at Cape Coast Teaching Hospital, Ghana

Abstract

Objective:To identify the socio-behavioral risk factors associated with cryptosporidiosis among HIV/AIDS patients with chronic diarrhea symptoms visiting the HIV referral clinic at Cape Coast Teaching Hospital, Ghana.Methods:A cross-sectional study was conducted among 50 HIV/AIDS patients with recurrent diarrhea. Questionnaires were administered to collect social and behavioral risk factors associated withCryptosporidiumand other opportunistic protozoan parasitic infections in HIV patients. Stool samples were collected for the diagnosis of enteric protozoan pathogens using modified Ziehl-Neelsen and acid-fast staining methods. CD4+cells counts of study subjects were obtained from patients clinical records. The data obtained were analyzed using Pearson chi-square and multivariate-adjusted statistics tool on SPSS 16 for Windows.Results:Twenty-seven (54%) of the subjects were infected with enteric protozoan pathogens. The prevalences ofCryptosporidium,CyclosporaandMicrosporidiuminfections were 46%, 32% and 16%, respectively.Cryptosporidiuminfection was significantly associated with drinking water (×2=13.528, p<0.001),Cyclosporawas associated with the type of drinking water (×2=14.931, p<0.001) and toilet facilities used by the study subjects (×2=12.463, p<0.01), whilesMicrosporidiuminfection was associated with hand washing behavior (×2=12.463, p<0.01). Enteric protozoans were frequently encountered among subjects with CD4+ T-cell count <200 cells/mm3. However, coinfection ofCyclospora spp&Cryptosporidiumspp was not observed in CD4+cell count <200 and >500 cells/mm3.Multivariate analysis showed that the risk factor forCryptosporidiuminfection among HIV/AIDS patients was the source of drinking water (pipe borne water 76.2% prevalence: sachet water 25%; OR=0.10, 95%CI: 0.03-0.39, p<0.001).Conclusion:We report the risk factor for exposure ofCryptosporidiuminfection among HIV/AIDS patients for the first time in Ghana. The contamination of drinking water by protozoan parasites should be a public health concern. These results provide the stepping block to understand the transmission dynamics ofCryptosporidiumand other opportunistic pathogens in HIV/AIDS infected patients in Ghana.
