Abstract
Purpose: The optimal treatment for infections due to Stenotrophomonas maltophilia has not been defined.
Methods: This was a multicenter, retrospective study of patients with S. maltophilia bacteremia between March 2010 to December 2023. Patients > 18 years with a positive blood culture growing S. maltophilia were included. Patients treated < 48 h or those with central line colonization were excluded. Clinical failure was defined as emergence of resistance during treatment, recurrent S. maltophilia bacteremia or death within 30 days. Outcomes for those treated with fluoroquinolone or trimethoprim-sulfamethoxazole monotherapy were compared using a propensity scored-adjusted full matching approach.
Results: 217 patients were included; 17% (37/217) patients had a history of transplant. The clinical failure rate was 16% (35/217); reasons for failure included death (n = 22), recurrent bacteremia (n = 12) or treatment-emergent resistance (n = 3). One patient each with recurrence and resistance also died within 30 days. Within 90 days, resistance developed in 15 patients. The most common treatment regimens were fluoroquinolones (n = 103) and trimethoprim-sulfamethoxazole (n = 45) as monotherapy. Use of high-dose trimethoprim-sulfamethoxazole did not improve clinical success rates. Combination therapy was employed in 10% (21/217) of patients. After applying full-matching criteria, there was no difference in rates of 30-day clinical failure (aOR = 1.02; 95% CI 0.25-3.82; P = 0.999) or mortality (aOR = 1.4; 95% CI 0.25-7.25; P = 0.727) among patients treated with fluroquinolone or trimethoprim-sulfamethoxazole monotherapy.
Conclusion: Monotherapy with fluoroquinolones or trimethoprim-sulfamethoxazole were used most commonly to treat S. maltophilia bacteremia across centers. Patient outcomes did not differ between treatment regimens and the overall rate of treatment-emergent resistance was low.
期刊介绍:
Infection is a journal dedicated to serving as a global forum for the presentation and discussion of clinically relevant information on infectious diseases. Its primary goal is to engage readers and contributors from various regions around the world in the exchange of knowledge about the etiology, pathogenesis, diagnosis, and treatment of infectious diseases, both in outpatient and inpatient settings.
The journal covers a wide range of topics, including:
Etiology: The study of the causes of infectious diseases.
Pathogenesis: The process by which an infectious agent causes disease.
Diagnosis: The methods and techniques used to identify infectious diseases.
Treatment: The medical interventions and strategies employed to treat infectious diseases.
Public Health: Issues of local, regional, or international significance related to infectious diseases, including prevention, control, and management strategies.
Hospital Epidemiology: The study of the spread of infectious diseases within healthcare settings and the measures to prevent nosocomial infections.
In addition to these, Infection also includes a specialized "Images" section, which focuses on high-quality visual content, such as images, photographs, and microscopic slides, accompanied by brief abstracts. This section is designed to highlight the clinical and diagnostic value of visual aids in the field of infectious diseases, as many conditions present with characteristic clinical signs that can be diagnosed through inspection, and imaging and microscopy are crucial for accurate diagnosis. The journal's comprehensive approach ensures that it remains a valuable resource for healthcare professionals and researchers in the field of infectious diseases.
