Time to clearance of abdominal septic focus and mortality in patients with sepsis. / Tempo para evacuação de foco séptico abdominal e mortalidade em portadores de sepse.

OBJECTIVE: To assess the relationship between time to focus clearance and hospital mortality in patients with sepsis and septic shock. METHODS: This was an observational, single-center study with a retrospective analysis of the time to clearance of abdominal septic focus. Patients were classified according to the time to focus clearance into an early (≤ 12 hours) or delayed (> 12 hours) group. RESULTS: A total of 135 patients were evaluated. There was no association between time to focus clearance and hospital mortality (≤ 12 hours versus > 12 hours): 52.3% versus 52.9%, with p = 0.137. CONCLUSION: There was no difference in hospital mortality among patients with sepsis or septic shock who had an infectious focus evacuated before or after 12 hours after the diagnosis of sepsis.

Hypoalbuminemia as a predictor of mortality in abdominal sepsis.

BACKGROUND: A level < 35 g/L of albumin (hypoalbuminemia) has been determined as a parameter to predict mortality and morbidity. METHOD: Prospective observational study, in a period of 12 months, to patients diagnosed with sepsis of abdominal origin, they are divided into two groups based on albumin levels (cut: 3.5 g/dL) to assess mortality between both groups. RESULTS: We studied 23 patients admitted to the intensive care unit. The mean albumin was 2.77 g/dL (± 0.71). When calculating the odds ratio (OR) that was a 23-fold greater risk of dying when hypoalbuminemia presented compared to the normal albumin group (OR = 23.3; 95% CI: 1,948 to 279.42). The mean albumin for patients who died was 2.04 g/dL (± 0.31) vs. 3.03 g/dL (± 0.35) (p = 0.02; 95% CI: -1.551 to -0.416). We do not assess morbidity, however, we identify a certain tendency to a longer stay in the ICU which is accompanied by a higher risk of complications and in the end a higher risk of mortality. CONCLUSION: We conclude that hypoalbuminemia represents a predictor of mortality in patients with abdominal sepsis.

ANTECEDENTES: Un valor de albúmina < 35 g/l (hipoalbuminemia) ha demostrado ser un parámetro para predecir mortalidad y morbilidad. MÉTODO: Estudio observacional, prospectivo, en un periodo de 12 meses, en pacientes con diagnóstico de sepsis de origen abdominal a quienes se dividió en dos grupos según las cifras de albúmina (corte: 3.5 g/dl) para valorar la mortalidad en ambos grupos. RESULTADOS: Estudiamos 23 pacientes ingresados a la unidad de terapia intensiva. La media de albúmina fue de 2.77 g/dl (± 0.71). Al calcular la odds ratio (OR) identificamos un riesgo 23 veces mayor de fallecer al presentar hipoalbuminemia en comparación con el grupo con albúmina normal (OR = 23.3; intervalo de confianza del 95% [IC 95%]: 1.948 a 279.42). La media de los valores de albúmina para los pacientes que fallecieron fue de 2.04 g/dl (± 0.31) vs. a 3.03 g/dl (± 0.35) para el otro grupo (IC 95%: −1.551 a −0.416; p = 0.02)]. Aunque no valoramos la morbilidad, identificamos cierta tendencia a un mayor tiempo de estancia en la unidad de terapia intensiva, lo que se acompaña de mayor riesgo de complicaciones y de un mayor riesgo de muerte. CONCLUSIÓN: La hipoalbuminemia representa un predictor de mortalidad en los pacientes con sepsis abdominal.

Tempo para evacuação de foco séptico abdominal e mortalidade em portadores de sepse / Time to clearance of abdominal septic focus and mortality in patients with sepsis

RESUMO Objetivo: Aferir a relação entre tempo para evacuação de foco e mortalidade hospitalar em portadores de sepse e choque séptico. Métodos: Estudo observacional, unicêntrico, com análise retrospectiva do tempo para evacuação de foco séptico abdominal. Os pacientes foram classificados conforme o tempo para evacuação do foco em grupo precoce (≤ 12 horas) ou tardio (> 12 horas). Resultados: Foram avaliados 135 pacientes. Não houve associação entre tempo para evacuação do foco e mortalidade hospitalar (≤ 12 horas versus > 12 horas): 52,3% versus 52,9%, com p = 0,137. Conclusão: Não houve diferença na mortalidade hospitalar entre pacientes com sepse ou choque séptico que tiveram foco infeccioso evacuado antes ou após 12 horas do diagnóstico de sepse.

What´s new in intraabdominal candidiasis in critically ill patients, a review.

A high prevalence of invasive candidiasis has been reported in recent years. Patients admitted to an intensive care unit are at the highest risk for invasive candidiasis, mostly due to the severity of their disease, immune-suppressive states, prolonged length of stay, broad-spectrum antibiotics, septic shock, and Candida colonization. Intraabdominal candidiasis comprises a range of clinical manifestations, from just the suspicion based on clinical scenario to fever, leukocytosis, increase in biomarkers to the isolation of the responsible microorganism. In critically ill patients with IAC prompt treatment and adequate source control remains the ultimate goal.

Multicenter Prospective Cohort Study of Renal Failure in Patients Treated with Colistin versus Polymyxin B.

Nephrotoxicity is the main adverse effect of colistin and polymyxin B (PMB). It is not clear whether these two antibiotics are associated with different nephrotoxicity rates. We compared the incidences of renal failure (RF) in patients treated with colistimethate sodium (CMS) or PMB for ≥48 h. A multicenter prospective cohort study was performed that included patients aged ≥18 years. The primary outcome was renal failure (RF) according to Risk, Injury, Failure, Loss, and End-stage renal disease (RIFLE) criteria. Multivariate analysis with a Cox regression model was performed. A total of 491 patients were included: 81 in the CMS group and 410 in the PMB group. The mean daily doses in milligrams per kilogram of body weight were 4.2 ± 1.3 and 2.4 ± 0.73 of colistin base activity and PMB, respectively. The overall incidence of RF was 16.9% (83 patients): 38.3% and 12.7% in the CMS and PMB groups, respectively (P< 0.001). In multivariate analysis, CMS therapy was an independent risk factor for RF (hazard ratio, 3.35; 95% confidence interval, 2.05 to 5.48;P< 0.001) along with intensive care unit admission, higher weight, older age, and bloodstream and intraabdominal infections. CMS was also independently associated with a higher risk of RF in various subgroup analyses. The incidence of RF was higher in the CMS group regardless of the patient baseline creatinine clearance. The development of RF during therapy was not associated with 30-day mortality in multivariate analysis. CMS was associated with significantly higher rates of RF than those of PMB. Further studies are required to confirm our findings in other patient populations.
