Distal sensory polyneuropathy among HIV-infected patients at Parakou University Hospital, Benin, 2011

Abstract : Distal sensory polyneuropathy (DSP) is the most frequent neurological complication among HIV patients, and its risk increases with use of highly active antiretroviral therapy (HAART). We aimed to assess the prevalence of DSP and the factors associated with it among HIV-infected outpatients treated at Parakou University Hospital. This cross-sectional study took place from April 15 to July 15, 2011, and included 262 patients. All patients underwent a neurological examination by two neurologists with training and clinical experience in these examinations and in the Brief Peripheral Neuropathy Screening (BPNS), which was the primary tool used here. Data from nutritional status (body mass index: BMI), social and demographic information, HAART status, and CD4 count were recorded. The factors associated with DSP were studied with multivariate analysis, using a logistic regression model and a significance level of 0.05. The study included 60 men (22.9 %). Patients' ages ranged from 16 to 74 years and averaged 36.8±10 years. All patients but one patient were infected by HIV type 1 only; that one was coinfected by types 1 and 2. The mean BMI was 22.5+/-4.2 kg/m2. In all, 213 (81.3 %) received HAART, and the mean CD4 count was 355.0 cells/mm3+/-236.1. The prevalence of DSP was 42.4 %. The factors associated with it on univariate analysis were age, marital status, HAART status, duration of HIV infection, and duration of HAART. Only advanced age (OR 1.8, 95 % CI 1.1-5.3) and HAART use (OR 2.3, 95 % CI 1.5-4.9) were associated with DSP in the multivariate analysis. The main symptoms were paresthesia (numbness:75.7%; burning: 39.6%; pins and needles sensation 32.4 %) and pain (23.4 %). Vibration perception at the toes was missing or reduced for 84.4 %. According to the sensory symptoms grade, 93.7 % of patients were classified in Grades 2 or 3. This study showed that the prevalence of DSP is high and that it is associated with age and HAART.
