Peripheral neuropathy in patients with HIV infection: consider dual pathology.

Two HIV infected patients presented with peripheral neuropathy, in one patient this was originally ascribed to HIV associated mononeuritis multiplex and in the other to stavudine. Investigations confirmed these diagnoses and in both cases genetic analysis identified a second hereditary aetiology: in the first patient hereditary neuropathy with liability to pressure palsies and in the second hereditary motor and sensory neuropathy.
