The burden of mucocutaneous conditions and the association with HIV-1 infection in a rural community in Uganda
To determine the prevalence of mucocutaneous conditions and their association with HIV-1 infection in a rural community in Uganda.
In a prospective cohort study, participants were recruited from a large population study and invited to attend a clinic every 3 months for a detailed medical interview and a thorough physical examination. All findings including mucocutaneous findings were coded onto a standard questionnaire.
By the end of 1996, 436 participants had provided 1450 person years of observation (pyo); 646 pyo in HIV-positives and 804 pyo in HIV-negatives. Overall, 70% of participants had a skin condition during follow-up, and although skin conditions were significantly more common in HIV-positive subjects, the background level in HIV-negative subjects was high (77.3% and 63.6%, respectively). Herpes zoster, thin/sparse hair, maculo-papular rash and prurigo were significantly more common in the HIV-positives. Kaposi sarcoma, palmar/plantar rash and herpes zoster had positive predictive values for HIV infection of over 80%. Oral conditions were found in over 40% of participants and were significantly more common in HIV-positive subjects. Oral candidiasis and Kaposi sarcoma were significantly more frequent among HIV-positives.
HIV infection increases the already high burden of mucocutaneous diseases in this rural population. We identified some conditions that are more common in HIV and others that can be used as indicators of HIV infection.
