Several case reports have suggested an association between acquired toxoplasmosis and polymyositis-dermatomyositis. Because the presence of anti-Toxoplasma IgM antibodies suggests recent infection, 58 patients with polymyositis-dermatomyositis (from two medical centers) were examined for the presence of IgM antibodies using a specific indirect immunofluorescent technique. Serum samples were also examined for antibodies using the Sabin-Feldman dye test and complement fixation methods. Of 58 patients with polymyositis-dermatomyositis, 29 (50 percent) had positive Sabin-Feldman dye test results and 14 (24 percent) had positive IgM immunofluorescent findings. This is higher than the expected frequency. None of the patients with negative Sabin-Feldman dye test results had IgM immunofluorescent antibodies. Furthermore, IgM immunofluorescent antibodies were associated with the presence and titer of both Sabin-Feldman dye test and complement fixation antibodies. Evidence that the presence of antinuclear antibody and rheumatoid factor did not influence these results is presented. Patients with muscular dystrophy and systemic lupus erythematosus (with or without myositis) did not have an increased frequency of anti-Toxoplasma IgM immunofluorescent antibodies.
