Pneumonia in pregnancy.

Pneumonia complicating pregnancy requires a prompt diagnosis and the institution of adequate supportive and antimicrobial therapy. In a patient with a classic presentation of pneumonia, the most likely pathogens are Streptococcus pneumoniae and Haemophilus influenzae. In a patient with an atypical presentation of pneumonia, Mycoplasma pneumoniae and Chlamydia pneumoniae are frequently encountered. In a patient suffering from acquired immunodeficiency syndrome (AIDS), Pneumocystis carinii is the most frequent pathogen. The antimicrobial therapy, therefore, has to be tailored to the sensitivity patterns of these pathogens in the community. Hospitalization is recommended for the pregnant patient diagnosed with pneumonia to ensure effective supportive care and minimize the risk of preterm labor and delivery.
