Perinatal mortality associated with intrauterine infection due to pseudomonads
Abstract:
Pseudomonads are common causes of nosocomial infections but are rarely implicated in perinatal disease. In a retrospective autopsy study we found that 9% of all acute congenital bacterial infections were due to Pseudomonas species. Premature rupture of membranes occurred in half the cases and clinical maternal amnionitis in two-thirds. One case was apparently nosocomial in origin. No known risk factors were implicated in any other case. Seven infants were stillborn and two died within a few hours. Congenital pneumonia, funisitis, and chorioamnionitis were found at autopsy. Intrauterine infection due to the pseudomonads poses a serious problem that has not been previously recognized.
Insights
Pseudomonas species cause serious congenital bacterial infections, leading to stillbirth or infant death. This study highlights the unrecognized threat of intrauterine pseudomonad infections.
Area of Science:
- Medical Microbiology
- Perinatal Medicine
- Infectious Diseases
Background:
- Pseudomonads are frequent causes of hospital-acquired (nosocomial) infections.
- Their role in perinatal and congenital diseases is typically considered rare.
Purpose of the Study:
- To investigate the prevalence and characteristics of congenital infections caused by Pseudomonas species.
- To determine the clinical significance of intrauterine pseudomonad infections.
Main Methods:
- Retrospective autopsy study of congenital bacterial infections.
- Analysis of cases attributed to Pseudomonas species.
Main Results:
- Pseudomonas species accounted for 9% of all acute congenital bacterial infections studied.
- Associated conditions included premature rupture of membranes (50%) and maternal amnionitis (67%).
- Infections led to stillbirth (7 infants) or early neonatal death (2 infants), with findings of congenital pneumonia, funisitis, and chorioamnionitis.
Conclusions:
- Intrauterine infections caused by pseudomonads represent a significant and previously unrecognized problem in perinatal health.
- Prompt recognition and management are crucial for affected neonates.
