Using a histochemical method, 5'-nucleotidase activity was investigated in 80 muscle biopsy specimens, including specimens from eight patients with muscular dystrophy, 18 with nonspecific type II fiber atrophy, 15 with polymyositis, and 29 histologically normal controls. An interstitial reaction for 5'-nucleotidase was associated with an inflammatory infiltrate in 19 of 21 positive cases. Of the 15 cases of polymyositis, 14 showed an extensive interstitial reaction surrounding most of the myofibers and extending well away from the areas infiltrated by inflammatory cells. The extensive nature of this reaction makes 5'-nucleotidase activity a useful adjuvant in the diagnosis of inflammatory muscle disease.

This review is focused on recent reports of sporadic inclusion body myositis (sIBM), myopathy in patients with human immunodeficiency virus type 1 (HIV) infection, and necrotizing autoimmune myopathy with antibodies to signal recognition particle. The sIBM articles cover associations with certain genetic polymorphisms, the possible pathogenic role of anti-cytosolic 5'-nucleotidase 1A antibody, and disease-related burden and health care costs. Another article addressed the possible pathogenic role of signal recognition particle antibody in necrotizing myopathy. A series of HIV patients with overlapping features of sIBM and polymyositis are highlighted as is a report of a patient with HIV and late-onset rod-body myopathy that may have improved with immunotherapy.
