title: [Chlamydia pneumoniae infection associated with autoimmune hemolytic anemia due to warm antibodies].
abstract: Chlamydia pneumoniae has often been implicated in respiratory tract infections concomitant with other pathogens. Although this agent has also been associated with other nonrespiratory diseases, to our knowledge it has never been described with autoimmune hemolytic anemia. We present a case of pneumonia in which C. pneumoniae was found in association with another important respiratory pathogen, Legionella, and with hemolytic autoimmune IgG to warm antibodies, an entity that has not been reported previously with this or any other germ of the genus Chlamydia.
