Increased incidence of symptomatic peripheral neuropathy among adults receiving stavudine- versus zidovudine-based antiretroviral regimens in Kenya.J Neurovirol. 2012 Jun; 18(3):200-4.JN
The incidence of peripheral neuropathy (PN) among adults initiating antiretroviral therapy (ART) containing stavudine (d4T) versus zidovudine (ZDV) is not well described. We compared 1-year incidence between d4T- and ZDV-based regimens in adults initiating ART in a programmatic setting in Kenya. Of 1,848 adults on ART, 1,579 (85 %) initiated d4T-based and 269 (15 %) initiated ZDV-based regimens. One-year incidence of symptomatic PN per 100 person-years was 21.9 (n=236) among d4T users and 6.9 (n=7) among ZDV users (P=0.0002). D4T was associated with 2.7 greater risk of PN than ZDV (adjusted hazard ratio, 2.7, P=0.009). In settings with continued d4T use, such as Africa, the effects of d4T on PN compared to ZDV should be considered when choosing ART regimens.
