HIV polymyositis tương tự như bệnh ở bệnh nhân không nhiễm HIV và có thể cải thiện với corticosteroid hoặc thuốc ức chế miễn dịch. Một số bệnh nhân với các rối loạn lãng phí HIV, có thể đáp ứng oxandrolone. Tiên lượng phụ thuộc vào nguyên nhân cụ thể viêm cơ. Đối với một hội chứng không liên quan đến virus HIV | 379 drugs patients may require surgical drainage of the abscess or removal of the parasite. HIV polymyositis is similar to disease in non-HIV patients and may improve with corticosteroids or immunosuppressive medications. Some patients with the HIV wasting disorder may respond to oxandrolone. The prognosis depends on the specific cause of the myositis. For a non-HIV Prognosis related viral syndrome the disease is usually self-limiting and prognosis is good. Where there is HIV infection or opportunistic infection the prognosis is poor. Removal of isolated parasites coupled with anti-protozoal medications may be all that is required to treat parasitic myositis. Banker BQ 1994 Parasitic myositis in myology.

B Normal dystrophin staining. C Loss of dystrophin staining in DMD Distribution Proximal muscles are more affected than distal muscles. Infants may have generalized hypotonia and be described as floppy . Time course Progressive disorder resulting in significant disability in most children. Onset age DMD starts at age 3-5 years with symmetric proximal greater than distal weakness in the arms and legs. By 6-9 years they characteristically exhibit a positive Gower s sign and by 10-12 years patients often fail to walk. Clinical syndrome DMD results in a progressive muscular weakness .
