  • Title: Human immunodeficiency virus-associated myopathy: analysis of 11 patients.
    Author: Simpson DM, Bender AN.
    Journal: Ann Neurol; 1988 Jul; 24(1):79-84. PubMed ID: 2843080.
    Abstract:
    Neuromuscular disorders reported in association with human immunodeficiency virus (HIV) infection include several forms of peripheral neuropathy and polymyositis. We report 11 patients with HIV-associated myopathy. Five patients with acquired immunodeficiency syndrome (AIDS), 2 with AIDS-related complex, and 4 otherwise asymptomatic HIV-infected patients developed progressive proximal muscle weakness. Serum creatine phosphokinase levels were elevated and electromyography revealed abnormal spontaneous activity and myopathy in most patients. All 8 muscle biopsy specimens showed fiber necrosis. Four had inflammatory infiltrates, and nemaline rod bodies were prominent in 3. Immunosuppressant therapy in 5 patients resulted in improvement. Attempts at viral localization in 4 muscle biopsy specimens were unsuccessful. These findings suggest a distinct association between HIV infection and myopathy with features atypical for polymyositis.
