Infectious Diarrhoea in Antiretroviral Therapy-Naive HIV/AIDS Patients in Kenya

Journal ArticleDiarrhoea is a significant cause of morbidity and mortality in immunocompromised patients. The objectives of this study were to investigate the aetiological agents, risk factors and clinical features associated with diarrhoea in HIV/AIDS patients in Kenya. Sociodemographic, epidemiological and clinical datawere obtained for 164 HIV/AIDS patients (70 with and 94 without diarrhoea) recruited from Kenyatta National Hospital, Kenya. Stool samples were examined for enteric pathogens by microscopy and bacteriology. Intestinal protozoa and fungi were identified in 70% of patients, more frequently in those with diarrhea (p,0.001). Helminths were detected in 25.6% of patients overall, and bacterial pathogens were identified= in 51% of patients with diarrhoea. Polyparasitism was more common in patients with diarrhoea than those without (p,0.0001). Higher CD4+ T-cell count (OR ¼ 0.995, 95% CI 0.992–0.998) and water treatment (OR ¼ 0.231, 95% CI 0.126–0.830) were associated with a lower risk of diarrhoea, while close contact with cows (OR ¼ 3.200, 95% CI 1.26–8.13) or pigs (OR ¼ 11.176, 95% CI 3.76–43.56) were associated with a higher risk of diarrhoea. Multiple enteric pathogens that are causative agents of diarrhoea were isolated from stools of antiretroviral therapy-naive HIV/AIDS patients, indicating a need for surveillance, treatment and promotion of hygienic practices
