Introdução: Devido ao uso indiscriminado de antibióticos, infecção por Clostridium difficile (ICD) tem aumentado significativamente em frequência e severidade ao longo dos anos, acarretando em maior morbidade e mortalidade além de maiores custos hospitalares. Objetivo: O objetivo deste estudo é avaliar os fatores de risco e fatores associados à pior prognóstico por colite Clostridium difficile em pacientes adultos internados. Desenho do estudo: Estudo de caso-controle retrospectivo Métodos: Em um Hospital terciário, durante o período de 1° de janeiro de 2010 a 31 de julho de 2012, foram comparados 75 pacientes com colite por Clostridium difficile documentada com 75 controles correspondentes com diarreia de origem nosocomial devido a outras etiologias. Foram identificados pacientes com ICD aqueles cuja pesquisa de toxinas A ou B, exame imunoenzimático VIDAS®, foi positiva ou aqueles com exames negativos ou indeterminados para estas toxinas com colonoscopia compatível com colite por Clostridium difficile. Todas variáveis clínicas e microbiológicas com P <0,10 na análise univariada, foram incluídos na análise de regressão logística múltipla afim de avaliar potenciais fatores de risco e fatores de pior prognóstico associados a colite por C. difficile entre pacientes com diarréia internados. Na análise multivariada, variáveis independentes permaneceram se P < 0,05. Resultados: Uso prévio de antibióticos (OR, 13.3; 95% CI, 1.40-126.90), presença de distensão abdominal (OR, 3.85; 95% CI, 1.35-10.98) e leucócitos fecais (OR, 8.79; 95% CI, 1.41-54.61) diante a apresentação de diarreia foram de preditores de infecção por Clostridium difficile. Por outro lado, presença de anorexia esteve negativamente associado com ICD (OR, 0.15; 95% CI, 0.03-0.66). Em relação a análise multivariada, alimentação por sonda naso-entérica (SNE) mostrou-se o único fator independente associado a pior prognóstico, este avaliado como: pacientes admitos em unidade de terapia intensiva (UTI), mortalidade hospitalar e falência de tratamento (OR, 3.75; 95% CI, 1.24-11.29). Conclusão: Uso de antibiótico foi fator de risco para colite por Clostridium difficile observado neste estudo. O uso de suporte nutricional por SNE foi o único fator associado a pior prognóstico.Background: Due to the indiscriminate use of antibiotics, Clostridium difficile infections (CDI) is increasing in frequency and severity over the years, resulting in increased morbidity and mortality as well as higher hospital costs. Objective: The aim of this study was to evaluate factors associated with Clostridium difficile infection among adult patients with hospital-acquired diarrhea and factors associated with poor prognosis. Study design: Retrospective case-control study. Methods: In a terciary hospital, during the period of january 1° 2010 to 31 july 2012, were compared 75 patients with documented Clostridum difficile colitis with 75 matched controls with hospital-acquired diarrhea secondary to an etiology other than Clostridium difficile. Patients with colits were identified by a positive toxins A or B, an immunoenzymatic test VIDAS®, or by a negative or indeterminate test for these toxins with colonoscopy compatible with Clostridium difficile colitis. All clinical and microbiological variables with a P value <0.10 in the univariate analysis were included in the stepwise multiple logistic regression to identify potential factors associated with C. difficile etiology among patients with hospital-acquired diarrhea and factors associated with poor prognosis among those patients with documented C.difficile colitis. In the multivariate model, independent variables remained in the model if the P value was < 0.05. Results: Previous antibiotic treatment (OR, 13.3; 95% CI, 1.40-126.90), presence of abdominal distension (OR, 3.85; 95% CI, 1.35-10.98) and fecal leukocytes (OR, 8.79; 95% CI, 1.41-54.61) at the onset of diarrhea were predictors of CDI. On the other hand, presence of anorexia was negatively associated with C.difficile etiology (OR, 0.15; 95% CI, 0.03-0.66). Upon multivariate analysis, enteral tube feeding was the only factor independently associated with a composite endpoint which included in-hospital mortality, ICU admission and treatment failure (OR, 3.75; 95% CI, 1.24-11.29). Conclusion:.Previous antibiotic use was risk factor for clostridium difficile colits. In this study tube feeding was the only factor associated with poor prognosis

Clinical Study Outcomes and Risk Factors Associated with Clostridium difficile Diarrhea in Hospitalized Adult Patients

Background. The epidemiology of Clostridium difficile infection has changed over time. Therefore, it is essential to monitor the characteristics of patients at risk of infection and factors associated with poor prognosis. Objective. To evaluate factors associated with C. difficile infection and with poor prognosis in those with documented C. difficile colitis. Methods. A retrospective case-control study of 75 patients with documented C. difficile colitis and 75 controls with hospital-acquired diarrhea of other causes. Stepwise multiple logistic regression was used to identify factors associated with C. difficile infection among patients with hospital-acquired diarrhea. Results. Previous antibiotic treatment (odds ratio (OR), 13.3; 95% confidence interval (CI), 1.40-126.90), abdominal distension (OR, 3.85; 95% CI, 1.35-10.98), and fecal leukocytes (OR, 8.79; 95% CI,) are considered as predictors of C. difficile colitis; anorexia was negatively associated with C. difficile infection (OR, 0.15; 95% CI, 0.03-0.66). Enteral tube feeding was independently associated with a composite outcome that included in-hospital mortality, intensive care unit admission, and treatment failure (OR, 3.75; 95%CI,. Conclusions. Previous antibiotic use and presence of fecal leukocytes in patients with hospital-acquired diarrhea are associated with C. difficile colitis and enteral tube support with complications associated with C. difficile colitis
