Persistent Chlamydia Pneumoniae serology is related to decline in lung function in women but not in men

Chlamydia pneumoniae (C pn) infection causes an acute inflammation in the respiratory system that may become persistent, but little is known about the long-term respiratory effects of C pn infections. Aim: To estimate the long term respiratory effects of C pn with change in forced expiratory volume in one second (FEV1) and forced expiratory capacity (FVC) as a main outcome variable.
