Objective:
To determine the accuracy of a screening examination for distal sensory peripheral neuropathy (DSPN) performed by nonphysician clinicians and to explore the associations between DSPN and clinical features in HIV-infected persons.
Methods:
A case-control study of a volunteer sample of 226 HIV-infected individuals was performed. An interview, focusing on risks and symptoms of DSPN, and a screening neurologic examination were performed.
Results:
Compared with the neurologist's examinations, the clinicians' examination was sensitive (92 to 95%) but not as specific (71 to 84%) for the diagnosis of DSPN. After excluding 27 patients with confounders, 42 of 199 patients (21%) had DSPN. This was associated significantly with neurotoxic nucleoside antiretroviral use and with more advanced HIV disease. Of the 42 patients with DSPN, 30 (71%) had no neuropathy symptoms.
Conclusions:
A brief examination performed by trained nonphysician clinicians can be used to screen for DSPN in HIV-infected persons. Asymptomatic DSPN is common in these individuals.
