Table 1. Peripheral Neuropathy in HIV-Infected Patients

Diagnosis Disease Stage Clinical Symptoms Neurologic Signs Standard Therapy Experimental Therapy

DSP Late Distal symmetric numbness, tingling, and burning sensations; paresthesias or aching Stocking-glove sensory loss, depressed or absent ankle reflexes Neurotoxin withdrawal, analgesics, topical agents, anticonvulsants, tricyclic antidepressants, acupuncture rhNGF, Lidoderm (5% lidocaine gel), prouridine
IDP Early to late Progressive weakness, paresthesias Muscle weakness, mild sensory loss, areflexia Early: Corticosteroids, plasmapheresis, high-dose intravenous immunoglobulinLate: Ganciclovir, foscarnet, cidofovir (late-stage HIV disease) None
MM Early (limited)Late (progressive) Foot or wrist drop, facial weakness, focal pain Multifocal cranial and peripheral neuropathies Early: NoneLate: Ganciclovir, foscarnet, and cidofovir (singly or in combination) None
PP Late Lower extremity weakness, sphincter dysfunction, paresthesias Flaccid paraparesis; saddle distribution anesthesia; depressed ankle and knee reflexes Ganciclovir, foscarnet, and cidofovir (singly or in combination) None
AN Late to early Orthostatic dizziness, syncope, diarrhea, anhidrosis, palpitations, impotence, urinary dysfunction Orthostatic hypotension, pupillary abnormalities, sweating dysfunction, resting tachycardia Discontinuation of offending drugs, fluorocortisone, antiarrhythmic agents, fluid and electrolyte replacement None

DSP, distal sensory polyneuropathy; IDP, inflammatory demyelinating polyneuropathy; MM, mononeuritis multiplex; PP, progressive polyradiculopathy; AN, autonomic neuropathy; rhNGF recombinant human nerve growth factor.
