Sex disparities in outcomes among adults on long-term antiretroviral treatment in northern Nigeria.

BACKGROUND: There are conflicting reports of sex differences in HIV treatment outcomes in Africa. We investigated sex disparities in treatment outcomes for adults on first line antiretroviral treatment (ART) in Nigeria. METHODS: We compared clinical and immunologic responses to ART between HIV-infected men (n=205) and women (n=140) enrolled in an ART program between June 2004 and December 2007, with follow-up through June 2014. We employed Kaplan-Meier estimates to examine differences in time to immunologic failure and loss to follow-up (LTFU), and generalized estimating equations to assess changes in CD4+ count by sex. RESULTS: Men had lower baseline mean CD4+ count compared to women (327.6 cells/µL vs 413.4, respectively, p<0.01). Women had significantly higher rates of increase in CD4+ count than men, even after adjusting for confounders, p<0.0001. There was no significant difference in LTFU by sex: LTFU rate was 2.47/1000 person-months (95% CI 1.6-3.9) in the first five years for men vs 1.98/1000 person-months (95% CI (1.3-3.0) for women. There was no difference in time to LTFU by sex over the study period. CONCLUSIONS: Women achieved better long-term immune response to ART at baseline and during treatment, but had similar rates of long-term retention in care to men. Targeted efforts are needed to improve immune outcomes in men in our setting.

AIDS mortality in a tertiary health institution: A four-year review.

Africa contains 70% of adults and 80% of children living with AIDS in the world and has buried 75% of the 21.8 million worldwide who have died of AIDS since the epidemic began. Nigeria, the most populous country in Africa, has 5.8% of her adult population having HIV infection at the end of 2003. We reviewed the causes of death among AIDS patients in Aminu Kano Teaching Hospital Kano, Nigeria over four years. Four-hundred-fifty-five (9.9%) of the 4,574 adult medical admissions were due to HIV/AIDS-related diagnosis. HIV/AIDS admissions increased progressively from 45 cases in 2001 to 174 in 2004. HIV/AIDS caused 176 deaths over the period giving an HIV-related mortality of 38.7%. This also showed a gradual increase from 24 deaths in 2001 to 61 deaths in 2004. The most common causes of death were tuberculosis (33.4%), septicemia (23.8%), advanced HIV disease (9.1%), meningitis (7.4%), other pulmonary infections (5.1%) and Kaposi's sarcoma (4.5%). The present dismal situation of patients living with HIV/AIDS calls for enhanced strategies to decrease the mortality trend observed. With the introduction of affordable highly active antiretroviral therapy (HAART) in several centers in Nigeria, it is hoped that infected patients can be made to live longer.

Xanthoma disseminatum in a black African woman.

PURPOSE: To report a partial steroid response of xanthoma disseminatum in a black African woman. DESIGN: Case report and literature review. METHODS: Histopathologic study of cutaneous tumour and clinical follow-up. RESULTS: A 32-year-old black African woman with mucocutaneous xanthomatosis and dysphonia, which partially responded to treatment with steroids. CONCLUSIONS: Xanthoma dissseminatum is a rare condition for which there is no medical treatment. We reported the condition in a black African woman whose skin and CNS symptoms regressed remarkably within 22 weeks of steroid therapy.
