Overview
Psittacosis, if left untreated presents as a flu like symptom or an atypical pneumonia in most cases. In the first week of psittacosis the symptoms mimic typhoid fever; prostrating high fevers, arthralgias, diarrhea, conjunctivitis, epistaxis and leukopenia. Headache can be so severe that suggests meningitis and some nuchal rigidity is not unusual. Towards the end of first week stupor or even coma results in severe cases. The second week is more of acute bacteremic pneumococcal pneumonia with continuous high fevers, cough and dyspnea. Some complications include respiratory failure, acute tubular necrosis, hemolytic anemia, endocarditis, hepatitis, encephalitis and in some fatal cases death.
Natural History, Complications and Prognosis
Natural History
Psittacosis presents chiefly as an atypical pneumonia. In the first week of psittacosis the symptoms mimic typhoid fever: prostrating high fevers, arthralgias, diarrhea, conjunctivitis, epistaxis and leukopenia. Headache can be so severe that suggests meningitis and some nuchal rigidity is not unusual. Towards the end of first week stupor and coma result in severe cases. The second week is more akin of acute bacteremic pneumococcal pneumonia with continuous high fevers, cough and dyspnea. If untreated it progresses as following:
- Stage of flu like syndrome
- Moderate pneumonia with X ray findings
- Severe pneumonia
- Respiratory failure and sepsis
Complications
Complications that can develop as a result of psittacosis are:
- Respiratory failure
- Acute tubular necrosis
- Hemolytic anemia[1]
- Endocarditis
- Hepatitis
- Myocarditis
- Arthritis
- Chronic follicular conjunctivitis
- Lymphoma
- Gestational psittacosis
- Encephalitis - rare but fatal
Prognosis
Psittacosis is a treatable infectious disease. With appropriate antibiotic therapy, prognosis is good. If the disease is complicated by renal failure or respiratory failure, prognosis is poor.
