Abstract:
We report a case of pyelonephritis and secondary bacteraemia caused by Veillonella species during pregnancy. Veillonella is part of the normal flora from the oral cavity, gut and vagina. However, because Veillonella is usually isolated from cultures of clinical specimens as part of commensal flora, it is frequently regarded as a contaminant. In the present case, Veillonella was isolated from the patient's urine and blood samples that showed evidence of pyelonephritis and secondary bacteraemia. We found that ureteral stenting is an extremely effective therapeutic option for pregnant woman with hydronephrosis and clear signs and symptoms of urosepsis.
Insights
This case study highlights a rare pregnancy complication: pyelonephritis and bacteremia caused by Veillonella species. Ureteral stenting proved effective for treating urosepsis in this pregnant patient.
Area of Science:
- Microbiology
- Obstetrics & Gynecology
- Infectious Diseases
Background:
- Veillonella species are common commensal flora in the oral cavity, gut, and vagina.
- These bacteria are often dismissed as contaminants in clinical cultures due to their usual non-pathogenic role.
Observation:
- A pregnant patient presented with pyelonephritis and secondary bacteremia.
- Veillonella species were isolated from both urine and blood samples, confirming a significant infection.
Findings:
- The study identified Veillonella species as a causative agent of pyelonephritis and bacteremia during pregnancy.
- Ureteral stenting was found to be a highly effective treatment for hydronephrosis and urosepsis in this scenario.
Implications:
- This case expands the understanding of Veillonella's pathogenic potential, particularly in pregnant women.
- Ureteral stenting should be considered a valuable therapeutic option for managing severe urinary tract infections and sepsis in pregnancy.
