IgA nephropathy and polymyositis: a rare association.

Polymyositis is a systemic and idiopathic inflammatory myopathy that, besides muscle manifestation, may occur with respiratory involvement, gastrointestinal tract and rarely renal involvement. In this latter, there are only two cases of IgA nephropathy, but both in dermatomyositis. On the other hand, we reported, for the first time, a case of IgA nephropathy in polymyositis.

[Autoimmune hepatitis and dermatomyositis: a rare association].

The association between autoimmune hepatitis and idiopathic inflammatory myopathies has been rarely described in literature. To our knowledge, there are only five reports of autoimmune hepatitis, all coursing with polymyositis. In the present work, we describe a female patient at the age of 58 with cutaneous lesions (heliotrope), progressive proximal muscle weakness of four limbs and constitutional symptoms for 12 months, and worsened two months ago.

Adult dermatomyositis: experience of a Brazilian tertiary care center.

Objective: To report the results of a retrospective cohort involving 139 patients with dermatomyositis, conducted from 1991 to 2011.

Methods: All patients met at least four of the five Bohan and Peter criteria (1975).

Results: The patients' mean age at disease onset was 41.

Analysis of metabolic syndrome in adult dermatomyositis with a focus on cardiovascular disease.

Objective: To evaluate the frequency of metabolic syndrome in dermatomyositis (DM) patients and to analyze the possible association of metabolic syndrome with traditional cardiovascular disease (CVD) risk factors and DM-related clinical and laboratory features.

Methods: The present cross-sectional single-center study included 84 DM patients and 105 healthy controls. Metabolic syndrome was diagnosed according to the National Cholesterol Education Program Adult Treatment Panel III.
