Are anti-Chlamydia pneumoniae antibodies prognosis indicators for peripartum cardiomyopathy?
GROUND: The authors recently pointed out an epidemiological relation between specific anti-Chlamydia pneumoniae antibodies and peripartum cardiomyopathy in Niamey (Republic of Niger). DESIGN: In this work, they studied the prognosis value of such specific antibodies. METHODS: The serological status for specific IgG, IgA and IgM anti-C. pneumoniae antibodies of 50 African women (age, mean+/-SD = 30.2 +/- 7 years) hospitalized in Niamey, with peripartum cardiomyopathy, was determined at the time of diagnosis. The diagnosis was categorized as ‘complete remission’ (13 patients, age = 29.3 +/- 6.5 years, observation delay = 27 months), ‘incomplete remission’ (27 patients, age = 30.7 +/- 7.6 years, observation delay = 14 months) and ‘deceased’ (10 patients, age = 30.3 +/- 6.2 years, observation delay = 13 months). The control group comprised 27 African women (age = 25.2 +/- 4.6 years), living in the same area. The Mann-Whitney and Fisher’s exact tests were used for the statistical comparison
