[Chlamydia trachomatis infection in mother and child; the importance of a complete history and efficient...

Area of Science:

• Pediatrics
• Infectious Diseases
• Neonatal Medicine

Background:

• Infants presenting with persistent cough pose diagnostic challenges for general practitioners and pediatricians.
• Maternal health history and condition are crucial in diagnosing infant respiratory illnesses.

Observation:

• A 4-week-old infant with persistent cough and dyspnea was hospitalized.
• The infant's mother presented with abdominal pain and elevated inflammatory markers, with a history of ectopic pregnancy.
• The infant developed purulent conjunctivitis, and initial diagnoses included viral bronchiolitis or whooping cough.

Findings:

• Chlamydia trachomatis (C. trachomatis) polymerase chain reaction (PCR) testing was positive in both the infant and mother.
• C. trachomatis pneumonia was confirmed as the cause of the infant's severe respiratory symptoms.

Implications:

• Chlamydia trachomatis pneumonia is an important, often overlooked, cause of infant cough.
• Comprehensive patient history and inter-specialist communication are vital for accurate diagnosis and management.
• This case highlights the need to consider atypical pathogens in infant respiratory infections.
