RESUMO
BACKGROUND: HIV drug resistance (HIV-DR) is rising in sub-Saharan Africa in both ART-naive and ART-experienced patients. OBJECTIVES: To estimate the level of acquired DR (ADR) and pre-treatment DR (PDR) across selected urban and rural sites in Southern Africa, in Mozambique. METHODS: We conducted two cross-sectional surveys among adult HIV patients (October 2017-18) assessing ADR and PDR. In the (ADR) survey, those on NNRTI-based first-line ART for ≥6 months were recruited (three sites). In the PDR survey, those ART-naive or experienced with ≥3 months of treatment interruption prior were enrolled (eight sites). RESULTS: Among 1113 ADR survey participants 83% were receiving tenofovir (TDF)/lamivudine (3TC)/efavirenz (EFV). The median time on ART was 4.5 years (Maputo) and 3.2 years (Tete), 8.3% (95% CI 6.2%-10.6%, Maputo) and 15.5% (Tete) had a VL ≥â1000 copies/mL, among whom 66% and 76.4% had NNRTI+NRTI resistance, and 52.8% and 66.7% had 3TC+TDF-DR. Among those on TDF regimens, 31.1% (Maputo) and 42.2% (Tete) were still TDF susceptible, whereas 24.4% and 11.5% had TDF+zidovudine (ZDV)-DR. Among those on ZDV regimens, 25% and 54.5% had TDF+ZDV-DR. The PDR survey included 735 participants: NNRTI-PDR was 16.8% (12.0-22.6) (Maputo) and 31.2% (26.2-36.6) (Tete), with a higher proportion (≥50%) among those previously on ART affected by PDR. CONCLUSIONS: In Mozambique, viral failure was driven by NNRTI and NRTI resistance, with NRTI DR affecting backbone options. NNRTI-PDR levels surpassed the WHO 10% 'alert' threshold. Replacing NNRTI first-line drugs is urgent, as is frequent viral load monitoring and resistance surveillance. Changing NRTI backbones when switching to second-line regimens may need reconsideration.
RESUMO
Clinic, epidemiological and microbiological characteristics of 128 episodes of cryptococcosis were retrospectively evaluated in 106 positive HIV patients hospitalized at the Paroissien Hospital on period 1996-2007. There were 75 male and 31 female patients, with a median age of 34 years, ranging from 20 to 68 years. Addiction to intravenous drugs was the main cause of HIV infection in 55 patients (51.9%). Cryptococcosis was detected as single episode in 85 patients (80.2%) and as relapse in 19 (17.9%). It appeared as the first marking disease in 36 patients (34.0%). Diagnosis was established in 116 episodes by CSF study (Indian ink, culture, antigen detection), in 9 cases by Cryptococcus sp. recovery from blood cultures, and in 3 cases by antigen detection in patient's serum with a latex reactive. Neurological symptomatology, with headache and fever as the most common signs, was presented by 89.6% of patients. Induction treatment was done in all cases with amphotericin B, and maintenance treatment was carried out with fluconazole. Mortality rate was 35.8%, being higher in those patients who had suffered relapses (41.3%) compared to those who presented a first episode of the mycosis (33.3%).
