Tenofovir-emtricitabine-efavirenz in HIV-I-infected adults in Senegal: a 96-week pilot trial in treatment-naive patients.

We report the results of a pilot open-label trial of a tenofovir (TDF)/emtricitabine (FTC)/efavirenz (EFV) combination conducted in Dakar, Senegal. Forty HIV-1-infected patients, naive of antiretroviral treatment and without active opportunistic disease, were included and followed through 96 weeks. At weeks 48 and 96, respectively, 82.5% and 85% of patients had HIV-1 RNA <400 copies/mL (72.5% and 77.5% with HIV-1 RNA <50 copies/mL). Between baseline and week 96, the mean (SD) CD4 count increased from 126 (102) to 338 (155) cells/mm(3). The mean (SD) creatinine clearance decreased from 92 (36) to 73 (19) mL/min (P = .001). Treatment adherence was at least 94% at all scheduled visits. The efficacy and tolerability of a TDF/FTC/EFV combination were high and similar to those observed in Northern countries. This drug combination can be recommended in limited-resource countries, as did the World Health Organization (WHO) and should be made readily available as a fixed-dose combination.

[Peripheral neuropathies and antiretroviral drugs. Preliminary results]. / Neuropathies peripheriques et traitements antiretroviraux. Etude clinique, électrophysiologique et neuropathologique des biopsies neuro-musculaires chez 18 patients vih séropositifs. Résultats préliminaires.

INTRODUCTION: In order to appreciate the antiretroviral drugs impact in the HIV positive patients with peripheral neuropathy, a clinical, electrophysiological and neurpathological study of nerve biopsies was performed. PATIENTS AND METHODS: A group of 8 HIV seropositive patients with peripheral neuropathy was compared with an other group of 10 HIV seropositive patients treated with multiple antiretroviral drugs. Electrophysiological examination with motor nerve conduction velocity (MNCV) mesure of the median and the sciatic popliteal nerve was followed by nerve biopsy. Nerve fragments carried out the neuropathological technics for morphological examination. RESULTS: Eighteen seropositive HIV patients (16 HIV-1 and 2 HIV-2) were included in this study. Six patients among them had motor and sensitive neuropathy of the four limbs and 2 patients had sensitive neuropathy associated with pyramidal signs. In fine, 1 patient had sensitive neuropathy with distal amyotrophy of the four limbs. Slow MNCV was observed in all the patients and more severe in the lower limbs. Nerve were unexciting in the lower limbs in 2 patients. Nerve biopsy showed severe axonal loss in all the patients treated but one. They associated axonal lesion in 5 cases and myelinated lesions in 2 cases. Two patients non treated had normal nerve biopsy. Axonal loss was mild in 2 cases and very severe in one case associated with non inflammatory demyelinated lesions. CONCLUSION: we observed more severe and more frequent nerve lesions in treated patients than in no treated patients, as at the clinical, electrophysiological and neuropathological examination. Antiretroviral drugs cause more frequently pain motor and sensitive neuropathies at usual posologies. The occurence of recrudescence of pain peripheral neuropathy under antiretroviral treatment allows to reconsider drugs posologies.

AIDS caused by HIV1 and HIV2 infection: are there clinical differences? Results of AIDS surveillance 1986-97 at Fann Hospital in Dakar, Senegal.

OBJECTIVE: To compare the clinical manifestations observed in AIDS patients infected with HIV2 and HIV1 infection. METHODS: The medical records of AIDS patients hospitalized between January 1986 and July 1997 at the Department of Infectious Diseases of Fann Hospital, Dakar, were reviewed. RESULTS: 599 hospitalizations (76%) were HIV1 seropositive patients, 137 (17%) were HIV2 seropositive patients and 54 (7%) were patients serologically dually reactive to HIV1 and HIV2. There was no significant difference in medium CD4 lymphocyte count between patients with HIV1 and HIV2 infection. Chronic diarrhoea and diarrhoea caused by bacterial infections were more frequently observed in HIV2-infected individuals. Oral candidiasis and chronic fever were more often noted in patients with HIV1 infection. Bacterial and cryptococcal meningitis was only observed among patients with HIV1 infection. CONCLUSIONS: Certain clinical differences were observed comparing AIDS patients with HIV1 and those with HIV2 infection. As there is no clear physiopathological explanation for these differences, additional studies with larger numbers of AIDS patients are needed to determine whether these differences are real.
