Abstract:
Stenotrophomonas maltophilia, a gram-negative bacillus well known to cause respiratory tract infections, is increasingly being reported to cause urinary tract infections (UTI). In our review of the literature comprising six articles, males were more prone to developing UTIs, with the mean age of the patients being 62.5 ±18.9 years. While several risk factors have been associated with the development of the disease, patients with underlying urological or nephrological diseases tend to develop a more severe illness. The organism was sensitive to trimethoprim-sulfamethoxazole (TMP-SMX) in the majority of cases. This systematic review also aims to shed light on the possible mechanisms of resistance adopted by the bacteria, modes of transmission, and strategies to prevent the transmission and development of the disease.
Insights
Stenotrophomonas maltophilia commonly causes respiratory infections but is increasingly linked to urinary tract infections (UTIs). This review highlights risk factors, treatment sensitivities, and resistance mechanisms for this emerging UTI pathogen.
Area of Science:
- Microbiology
- Infectious Diseases
- Urology
Background:
- Stenotrophomonas maltophilia, a Gram-negative bacillus, is a known cause of respiratory tract infections.
- There is a growing incidence of Stenotrophomonas maltophilia-associated urinary tract infections (UTIs).
Purpose of the Study:
- To systematically review the literature on Stenotrophomonas maltophilia UTIs.
- To identify patient demographics, risk factors, and clinical characteristics associated with these infections.
- To explore antimicrobial susceptibility, resistance mechanisms, transmission, and prevention strategies.
Main Methods:
- Systematic literature review of six articles.
- Analysis of patient data including age and gender.
- Evaluation of antimicrobial sensitivity patterns.
Main Results:
- Males were more frequently affected, with a mean patient age of 62.5 years.
- Underlying urological or nephrological diseases correlated with more severe illness.
- Trimethoprim-sulfamethoxazole (TMP-SMX) demonstrated sensitivity in most cases.
Conclusions:
- Stenotrophomonas maltophilia is an emerging cause of UTIs, particularly in older males.
- Prompt identification and appropriate antimicrobial selection, such as TMP-SMX, are crucial.
- Further research into resistance mechanisms and transmission is needed for effective prevention.
