Abstract:
Hepatic involvement is considered a rare complication of psittacosis. Occurrence of icteric hepatitis as the cardinal manifestation of the disease has been rarely reported. We describe two members of a family infected by psittacosis, in whom icteric hepatitis was the prominent expression of the disease. The diagnosis of psittacosis was confirmed by isolation of the pathogen and by detection of serum antibodies to Chlamydia species. No serological evidence for acute TWAR infection was found. Chlamydia psittaci was also isolated from the family's parrot.
Insights
Psittacosis, a rare complication, can present as icteric hepatitis. This family case study confirms Chlamydia psittaci infection as the cause of prominent liver disease.
Area of Science:
- Infectious Diseases
- Hepatology
- Zoonoses
Background:
- Psittacosis, caused by Chlamydia psittaci, is typically known for respiratory symptoms.
- Hepatic involvement in psittacosis is uncommon, with icteric hepatitis being exceptionally rare.
Observation:
- Two family members presented with psittacosis, where icteric hepatitis was the primary clinical manifestation.
- The family's pet parrot was identified as the source of Chlamydia psittaci infection.
Findings:
- Diagnosis was confirmed through pathogen isolation and serological antibody detection for Chlamydia species.
- No evidence of TWAR (Taiwan acute respiratory agent) infection was found, ruling out other causes.
Implications:
- Highlights the potential for psittacosis to manifest primarily as severe hepatitis.
- Emphasizes the importance of considering zoonotic infections in unexplained hepatitis cases.
- Underscores the role of avian reservoirs in human psittacosis transmission.
