Background:
Stenotrophomonas maltophilia is a gram-negative bacteria known for causing opportunistic and nosocomial infections in humans. S. maltophilia is an emerging pathogen of concern due to it's increasing prevalence, diverse disease spectrum, intrinsic multi-drug resistance and high mortality rates in immunocompromised individuals. S. maltophilia is a rare cause of neonatal sepsis associated with significant morbidity and mortality. The bacterium's multi-drug resistance poses a considerable challenge for treatment, with various mechanisms contributing to its resistance.
Case Presentation:
We report a case involving a 40-h-old male African neonate who exhibited symptoms of neonatal sepsis. The blood culture revealed Stenotrophomonas maltophilia, which was sensitive to ciprofloxacin and gentamicin but resistant to other antibiotics. Lumbar puncture for CSF could not be done because the father declined. We treated the newborn with the empirical first-line antibiotics as per the national guideline intravenous ampicillin and gentamicin for six days, and the child recovered fully with a repeated negative blood culture.
Conclusions:
This report describes a neonatal sepsis case caused by S. maltophilia, a multi-drug resistant bacteria and a rare cause of neonatal sepsis. We report that early detection of the bacterial and antimicrobial management based on local antibiogram data may be essential for successful patient's management.
Insights
Stenotrophomonas maltophilia rarely causes neonatal sepsis, but this case highlights successful treatment with early detection and appropriate antibiotics. Prompt management is key for positive outcomes in newborns with this multidrug-resistant bacteria.
Area of Science:
- Medical Microbiology
- Neonatal Medicine
- Infectious Diseases
Background:
- Stenotrophomonas maltophilia is a multidrug-resistant, gram-negative bacterium causing opportunistic infections.
- It is an emerging pathogen with increasing prevalence and high mortality in immunocompromised individuals.
- Neonatal sepsis due to S. maltophilia is rare but associated with significant morbidity and mortality.
Observation:
- A case of neonatal sepsis in a 40-hour-old infant is presented.
- Blood cultures identified Stenotrophomonas maltophilia, exhibiting resistance to multiple antibiotics but sensitivity to ciprofloxacin and gentamicin.
- Cerebrospinal fluid analysis was not performed due to parental refusal.
Findings:
- The neonate was treated with empirical intravenous ampicillin and gentamicin for six days.
- The infant demonstrated a full recovery with subsequent negative blood cultures.
- This case underscores the successful management of a rare neonatal sepsis caused by a multidrug-resistant organism.
Implications:
- Early detection of bacterial pathogens like S. maltophilia is crucial in neonatal sepsis cases.
- Antimicrobial management guided by local antibiogram data is essential for effective treatment.
- This case contributes to understanding the management of rare multidrug-resistant bacterial infections in neonates.
