Aggressive or Moderate Fluid Resuscitation in Acute Pancreatitis.

BACKGROUND: Early aggressive hydration is widely recommended for the management of acute pancreatitis, but evidence for this practice is limited. METHODS: At 18 centers, we randomly assigned patients who presented with acute pancreatitis to receive goal-directed aggressive or moderate resuscitation with lactated Ringer's solution. Aggressive fluid resuscitation consisted of a bolus of 20 ml per kilogram of body weight, followed by 3 ml per kilogram per hour. Moderate fluid resuscitation consisted of a bolus of 10 ml per kilogram in patients with hypovolemia or no bolus in patients with normovolemia, followed by 1.5 ml per kilogram per hour in all patients in this group. Patients were assessed at 12, 24, 48, and 72 hours, and fluid resuscitation was adjusted according to the patient's clinical status. The primary outcome was the development of moderately severe or severe pancreatitis during the hospitalization. The main safety outcome was fluid overload. The planned sample size was 744, with a first planned interim analysis after the enrollment of 248 patients. RESULTS: A total of 249 patients were included in the interim analysis. The trial was halted owing to between-group differences in the safety outcomes without a significant difference in the incidence of moderately severe or severe pancreatitis (22.1% in the aggressive-resuscitation group and 17.3% in the moderate-resuscitation group; adjusted relative risk, 1.30; 95% confidence interval [CI], 0.78 to 2.18; P = 0.32). Fluid overload developed in 20.5% of the patients who received aggressive resuscitation and in 6.3% of those who received moderate resuscitation (adjusted relative risk, 2.85; 95% CI, 1.36 to 5.94, P = 0.004). The median duration of hospitalization was 6 days (interquartile range, 4 to 8) in the aggressive-resuscitation group and 5 days (interquartile range, 3 to 7) in the moderate-resuscitation group. CONCLUSIONS: In this randomized trial involving patients with acute pancreatitis, early aggressive fluid resuscitation resulted in a higher incidence of fluid overload without improvement in clinical outcomes.

Addressing Profiles of Systemic Inflammation Across the Different Clinical Phenotypes of Acutely Decompensated Cirrhosis.

Background: Patients with acutely decompensated cirrhosis (AD) may or may not develop acute-on-chronic liver failure (ACLF). ACLF is characterized by high-grade systemic inflammation, organ failures (OF) and high short-term mortality. Although patients with AD cirrhosis exhibit distinct clinical phenotypes at baseline, they have low short-term mortality, unless ACLF develops during follow-up. Because little is known about the association of profile of systemic inflammation with clinical phenotypes of patients with AD cirrhosis, we aimed to investigate a battery of markers of systemic inflammation in these patients. Methods: Upon hospital admission baseline plasma levels of 15 markers (cytokines, chemokines, and oxidized albumin) were measured in 40 healthy controls, 39 compensated cirrhosis, 342 AD cirrhosis, and 161 ACLF. According to EASL-CLIF criteria, AD cirrhosis was divided into three distinct clinical phenotypes (AD-1: Creatinine<1.5, no HE, no OF; AD-2: creatinine 1.5-2, and or HE grade I/II, no OF; AD-3: Creatinine<1.5, no HE, non-renal OF). Results: Most markers were slightly abnormal in compensated cirrhosis, but markedly increased in AD. Patients with ACLF exhibited the largest number of abnormal markers, indicating "full-blown" systemic inflammation (all markers). AD-patients exhibited distinct systemic inflammation profiles across three different clinical phenotypes. In each phenotype, activation of systemic inflammation was only partial (30% of the markers). Mortality related to each clinical AD-phenotype was significantly lower than mortality associated with ACLF (p < 0.0001 by gray test). Among AD-patients baseline systemic inflammation (especially IL-8, IL-6, IL-1ra, HNA2 independently associated) was more intense in those who had poor 28-day outcomes (ACLF, death) than those who did not experience these outcomes. Conclusions: Although AD-patients exhibit distinct profiles of systemic inflammation depending on their clinical phenotypes, all these patients have only partial activation of systemic inflammation. However, those with the most extended baseline systemic inflammation had the highest the risk of ACLF development and death.

Diastolic dysfunction is a predictor of poor outcomes in patients with cirrhosis, portal hypertension, and a normal creatinine.

UNLABELLED: We investigated left ventricular diastolic dysfunction (LVDD) and its relationship with circulatory function and prognosis in cirrhosis with portal hypertension and normal creatinine. Conventional and tissue Doppler (TDI) echocardiography, systemic and hepatic hemodynamics, and the activity of endogenous vasoactive systems (AEVS) were measured prospectively in 80 patients. Plasma renin activity (PRA; >4 ng/mL/hour) was used as a surrogate of effective arterial blood volume. Patients were followed up for 12 months. Thirty-seven patients had LVDD (19 with grade 1 and 18 with grade 2). Left ventricular hypertrophy, left atrial volume, AEVS, and natriuretic peptide levels were significantly greater in patients with LVDD than without LVDD. Patients with grade 2 LVDD, compared to grade 1 LVDD and without LVDD, had significantly lower mean arterial pressure and higher Model for End-Stage Liver Disease (MELD) score, E-wave transmitral/early diastolic mitral annular velocity (E/e' ratio), cardiopulmonary pressures, PRA, and natriuretic peptide levels. Systolic and cardiac chronotropic function were significantly lower in patients with grade 2 LVDD than without LVDD. LVDD was more frequent in patients with ascites and increased PRA than patients without ascites or with ascites but normal PRA. Fourteen patients with LVDD developed hepatorenal syndrome (HRS) type 1 on follow-up. Survival was different according to degree of LVDD (without LVDD: 95%; grade 1 LVDD: 79%; grade 2 LVDD: 39%; P < 0.001). Independent predictive factors of mortality were MELD score and E/e' ratio. CONCLUSION: LVDD occurs simultaneously with other changes in cardiac structure and function and is associated with an impairment of effective arterial blood volume. LVDD is a sensitive marker of advanced cirrhosis, type 1 HRS development, and mortality.

Severe rhabdomyolysis due to rosuvastatin in a liver transplant subject with human immunodeficiency virus and immunosuppressive therapy-related dyslipidemia.

Statins are relatively safe first-line agents to use in the setting of dyslipidemia associated with immunosuppressive therapy in subjects undergoing liver transplantation, and also in HIV-infected patients with dyslipidemia due to antiretroviral drugs, especially ritonavir-boosted protease inhibitors. Rosuvastatin, a new statin, has demonstrated higher potency than previously released statins and is not extensively metabolized by the liver P450 system; therefore, the probability of deleterious pharmacokinetic interactions with commonly used immunosuppressants and antiretroviral drugs is reduced. We present the first case of severe rhabdomyolysis in a liver transplant patient receiving rosuvastatin for the treatment of immunosuppressive therapy-related grade IV dyslipidemia, an HIV-infected subject on protease inhibitor-sparing HAART, that resolved after rosuvastatin withdrawal, probably related to interactions between calcineurin inhibitors and hepatic rosuvastatin uptake transporters such as organic anion transporting polypeptides (OATPs).

Optimized protocol for diagnosis of acute ileitis.

BACKGROUND & AIMS: Suspected acute ileitis (AI) is a poorly defined clinical condition with multiple causes; its diagnostic protocol has not been standardized properly. We performed a prospective evaluation of the incidence and causes of AI to create a standard protocol for diagnosis. METHODS: The definition of AI included abdominal pain, diarrhea, fever, and at least 1 confirmatory imaging method (abdominal computed tomography scan or ultrasound) showing pathologic changes in the terminal ileum that indicated ileal inflammation. We studied all patients with a presumptive diagnosis of AI seen in the Emergency Room at the Ramón y Cajal Hospital in Madrid, from March 2005 to May 2007, according to a pre-established protocol. Sixty-six patients with primary AI were followed up for at least 6 months. RESULTS: An infectious cause was found in 33.3% of cases; the most frequently detected microorganism was Yersinia spp. A gynecologic condition was identified in 9.1% of cases initially diagnosed as AI, representing 13.95% of the cases among female patients. Crohn's disease was identified in 12.1% of patients. The diagnostic protocol led to negative results in 33.4% of the patients; 6.1% of patients did not complete the study. The initial diagnosis did not change among any of the patients during the follow-up period. CONCLUSIONS: This protocol led to a definitive diagnosis of AI in more than 60% of potential cases. The most common cause was acute infection. About 10% of cases were of gynecologic origin and about 12% of patients presented with Crohn's disease.
