    ABSTRACT: The epidemiologic, clinical and prognostic characteristics of Stenotrophomonas maltophilia bacteremias for a six-year period (January 1993 to December 1998) were reviewed. Twenty episodes of S. maltophilia bacteremia were include, which represented 0.62% of all bacteremias caused by gram-negative rods during that period. Seventy percent of bacteremias were clinically significant. The most common predisposing factors were the previous use of antimicrobial agents and the presence of vascular catheters. In most cases (57%), the origin of bacteremia was the intravascular catheter. The course of patients was favorable and all patients cured.

    ABSTRACT: OBJECTIVE: The primary objective of this review was to analyse the differences in efficacy between the administration of intermittent and continuous/expanded perfusion of piperacillin-tazobactam. Secondary objectives were to analyse the differences in safety, pharmacokinetic/pharmacodynamic parameters, and cost-effectiveness between the two forms of administration. METHOD: We performed two different independent bibliographic searches. We encountered a total of 38 articles, and the final number included in the study was 6. We analysed the articles and collected the following variables: design, treatment administered to each group, total number of patients and number of patients in each study, variables collected in each study, and results. RESULTS: We encountered significant differences in the primary variable in two of the six studies favouring continuous/expanded perfusion. The study by Lodise et al found differences (P=.04) in mortality (31.6% for intermittent perfusion vs 12.2% for continuous/expanded perfusion). The study by Lorente et al found differences (P=.001) in terms of clinical recovery (56.5% for intermittent perfusion vs 89.2% for continuous/expanded perfusion). As for secondary variables, we only found differences in one of the studies in relation to cost-effectiveness, in favour of the group who underwent continuous/expanded perfusion method. CONCLUSION: The analysed data suggest that continuous/expanded perfusion would be at least as effective as intermittent perfusion, and that it could be more effective in severe patients with infections from more resistant micro-organisms such as Pseudomonas aeruginosa. Additionally, this form of administration is more cost-effective, at least in theory.

    ABSTRACT: To study the infectious complications, mortality, and associated factors in heart transplant recipients. Prospective study of the first 69 heart transplantations performed from January 1991 until December 1996 in a university hospital. Description of clinical features of infectious complications during the first year after transplantation. Univariate and multivariate analyses of the risk factors associated with mortality and development of infectious complications. Seventy-three percent of patients had at least one infectious complication; the incidence was 1.13 episodes per patient-year. The etiology of complications was bacterial (50%), viral (31%), Pneumocystis carinii (5%), fungal (4%), and protozoal (4%). The opportunist organisms accounted for 42% of cases. Pneumonia was the most common complication (28%), followed by mucocutaneous herpetic reactivation (19%), bacteremia (13%), urinary tract infection (13%), cytomegalovirus disease (11.5%), pleural empyema (5%) and surgical wound infection (5%). Nosocomial pneumonia accounted for 50% of cases. Gram-negative rods accounted for 41% of pneumonia cases. A total of 62.5% of deaths were directly related to infectious complications. Factors independently associated with mortality were hospital origin at transplantation (RR = 4.5 [2-9], p = 0.034), development of infectious complications in the post-heart transplantation period (RR = 3.2 [1.2-12], p = 0.04) and a more prolonged hospital stay at ICU (p = 0.0004). The factor which was independently associated with the development of infectious complications was one or more severe episodes of acute rejection (RR = 1.5 [1.1-2.2], p = 0.04). Patients who developed infectious complications had a more prolonged accumulated annual hospital stay (p = 0.004) than those without infectious complications. Infectious complications are very common, prolong hospital stay, and are the first cause of mortality during the first year after transplantation. Bacteria are the most common etiology and pneumonia is the most common infection.
