title: [Pain therapy in HIV-associated polyneuropathy].
abstract: Only some patients with HIV-infection receive an adequate pain therapy. In later stages of HIV-infection up to 50% 6 of patients perform extraordinary doctor visits because of pain. Principally primary and secondary neuromanifestations of HIV-infection have to be differentiated. Rare forms of HIV-associated polyneuropathies represent mononeuropathy or mononeuritis multiple acute and chronic inflammatory demyelinating polyneuropathy and polyneuropathy caused by opportunistic infections. HIV-associated distal-symmetric polyneuropathy represents the most common form during HIV-infection with a prevalence up to 50%. Typical clinical symptoms and signs are pain, hyp- and dysaesthesia, diminuted deep tendon reflexes, motor deficits and autonomic disturbances. Always neurological examination and neurophysiologic investigation on the sural and peronaeal nerve are necessary for monitoring progression of polyneuropathy and as basics before starting antiretroviral therapy with neurotoxic substances. According to momentary opinion, HIV-associated distal-symmetric polyneuropathy represents no indication for antiretroviral therapy. Symptomatic therapy includes antiepileptic medication as gabapentine, antidepressive drugs as amitiptyline and additionally retarded opiates. Depressive disorders ma y accentuate pain problems a n d need psychotherapeutic and thymoleptic therapy. Special problems occur when neurotoxic substances evoke or deteriorate polyneuropathy. In these cases an individual therapeutic proceeding about continuation or discontinuation of neurotoxic medication is necessary. Symptoms of myopathy during HIV-infection are muscle pain, elevation of CK and typical changes of motor units detected by electromyography. In most cases biopsy is necessary for diagnosis of specific forms of HN-associated myopathy. HIV-associated polymyositis is treated by non-steroid analgetics, corticoids, immunoglobulines and plasmapheresis, myopathy induced by neurotoxic medication analogous to polyneuropathy.
