beta-hemolytic streptococcal infection appearing as persistent fetal circulation
American Journal of Diseases of Children (1960)
|August 1, 1982
Summary
Beta-hemolytic streptococcal infection is a newly identified cause of persistent fetal circulation (PFC) in neonates. This severe condition, often presenting with respiratory distress, has a high mortality rate, with only one survivor in this study.
Area of Science:
- Neonatology
- Pediatric Cardiology
- Infectious Diseases
Background:
- Persistent fetal circulation (PFC) is a critical condition in neonates characterized by the failure of circulatory transition after birth.
- Neonatal intensive care units (NICUs) manage complex cases, including those with respiratory distress and hypoxemia.
Observation:
- A retrospective study identified six neonates with beta-hemolytic streptococcal infection among 60 diagnosed with PFC over four years.
- These infants presented with respiratory distress, cyanosis, apnea, and progressive acidosis with hypoxemia.
Findings:
- Cardiac catheterization or contrast echoangiography confirmed PFC in affected neonates.
- Treatment involved mechanical ventilation, antibiotics, and supportive care, including tolazoline hydrochloride.
- The mortality rate was exceptionally high, with only one of the six infants surviving.
Implications:
- Beta-hemolytic streptococcal infection should be recognized as a potential cause of PFC.
- Early identification and management of streptococcal infections may be crucial for improving outcomes in neonates with PFC.
- Further research is warranted to understand the pathogenic mechanisms linking streptococcal infections to PFC.
