title: Pericarditis, pleural effusion, and pneumonitis with transient mitochondrial antibodies.
abstract: Four women with fever, arthromyalgias, pericarditis, pleural effusion, high erythrocyte sedimentation rates, and lymphopenia had mitochondrial antibodies in the serum in the absence of antinuclear antibody. Their illness lasted 5-12 weeks and the antibody test results became negative on remission. Absence of specific bacteriological findings, normal antistreptolysin O titres, resistance to antibiotics, and good response to steroids suggested that these cases represented a milder and less persistent form of the syndrome resembling systemic lupus erythematosus described by German authors.
