Abstract

We determined the incidence of and risk factors for distal sensory polyneuropathy (DSP) in individuals on HAART. Sixty-one HIV-positive subjects on HAART for at least 6 months and neuropathy free were retrospectively selected. The study included subjects who had previously tolerated d-drugs without developing DSP. Neuropathy incidence over 4 years was calculated. Cox proportional hazards models were used to determine risk factors associated with incident DSP. Nineteen subjects developed DSP over a mean follow-up of 2.4 years. Subjects never treated with a d-drug developed DSP at a rate of 21 cases per 100 person-years (95% CI, 8.9-33.7). Subjects with a history of d-drug treatment but not on a d-drug at enrollment developed DSP at a rate of 17 cases per 100 person-years (95% CI, 2.1-31.8). Those on d-drug treatment developed DSP at a rate of 25 cases per 100 person-years (95% CI, 8.7-41.6). Multivariable analysis identified age [hazard ratio (HR) = 1.09; p < 0.01] and low CD4(+) nadir [hazard ratio (HR) = 0.79; p = 0.03] as significant risk factors. Current or prior history of treatment with d-drug was not a significant risk factor for incident DSP in subjects who had previously tolerated d-drug treatment without developing a toxic DSP. Age and low CD4(+) are risk factors for incident DSP. However, current or prior history of d-drug treatment is not a significant risk factor for incident DSP in subjects who had previously tolerated d-drug treatment without developing a toxic DSP.
