To describe Stenotrophomonas maltophilia infection in children, we reviewed the medical records of patients with isolates from nonrespiratory sites and identified 85 episodes, 51 (60%) of which represented true infection. Forty-two episodes (82.4%) were hospital acquired. Commonly associated with S. maltophilia infection were underlying illness (in 90.2% of cases), previous hospitalizations (in 78.7%), previous antibiotic exposure (in 78.4%), and the presence of a central venous catheter (in 76.5%). Polymicrobial isolates were obtained in 70.6% of episodes; Pseudomonas aeruginosa and Acinetobacter species were the most common coisolates. Bloodstream infection was the most frequent clinical syndrome (32 [63%] of 51 episodes). Fever or sepsis occurred in 22 (69%) and shock in 10 (31%) of 32 episodes. Infection at other sites was less severe. The most active antibiotics in vitro were trimethoprim-sulfamethoxazole and ticarcillin-clavulanate. The overall and attributable mortality rates were 12.5% and 6.3%, respectively. S. maltophilia appears to be an important cause of nosocomially acquired bacteremia in children. The significance in children of isolation from other sites is less clear.

We report the case of a melioidosis-like abscess of the liver caused by Stenotrophomonas (Xanthomonas) maltophilia infection in a Chinese man living in Hungary. Although this appears to be the first documentation of a liver abscess of this origin in a nonimmunocompromised patient, our case report demonstrates that this common facultative pathogen can also cause liver abscess and sepsis. After repeated negative blood cultures, histological examinations of liver biopsies suggested the possibility of chronic melioidosis, but the microbiological examination performed directly on the same specimen identified a Stenotrophomonas maltophilia infection. Surgical drainage was performed and sulphamethoxazole/trimethoprim therapy was commenced, after which the patient recovered fully. The facultative pathogen S. maltophilia, which most often causes nosocomial infections, may cause severe sepsis and liver abscess. We wish to draw attention to the fact that the antibiotic sensitivity of S. maltophilia is not necessarily the same in vivo and in vitro. This can create difficulties in both diagnosis and treatment.

Stenotrophomonas maltophilia infection is of concern in patients with cancer. Antibiotics active against S. maltophilia are rarely used in the treatment of febrile neutropenia, making it important to identify the factors influencing mortality in cancer patients with S. maltophilia infection. The objective of this study was to analyze the clinical characteristics and outcomes of cancer and hemopathic patients with S. maltophilia infection and assess the factors influencing the mortality. The microbiology laboratory records of Erciyes University, Faculty of Medicine Hospital were reviewed to retrospectively identify patients with S. maltophilia infection between January 2007 and June 2011. A total of 38 patients (25 male, 13 female) were eligible for the study. The median age of the patients was 53 years. The underlying disease was hematological malignancy and disorders in 76.3 % (29 cases), solid tumors in 15.8 % (six cases), aplastic anemia in 7.9 % (three cases), while 18.4 % (seven cases) were hematopoietic stem cell transplantation (HSCT) recipients. An indwelling central venous catheter was used in 32 cases (84.2 %). Twenty-seven patients (71.1 %) were neutropenic at the onset of infection. Nine patients (23.7 %) were receiving corticosteroid therapy. The overall 14-day mortality rate was 50 %. Three of the patients received empirical antibacterial treatment, and three HSCT recipients received trimethoprim-sulfamethoxazole prophylaxis, which is active against S. maltophilia. Severe sepsis (OR 13.24, 95 % confidence interval (CI) 1.62-108.57) and the duration of the treatment (OR 0.73, 95 % CI 0.60-0.90) were related to death based on logistic regression analysis findings. In immunocompromised hematology-oncology patients with severe sepsis, S. maltophilia should be considered as a possible cause of infection, and should be given effective empirical antibiotic treatment immediately; the antimicrobial spectrum may be narrowed according to results of antibiotic susceptibility test.
