ABSTRACT Pancreatic necrosis is a serious complication of acute pancreatitis. The identification of simple laboratory tests to detect subjects at risk of pancreatic necrosis may direct management and improve outcome. This study focuses on the association between routine laboratory tests and the development of pancreatic necrosis in patients with acute pancreatitis.
In a cohort of 185 patients with acute pancreatitis prospectively enrolled in the Severity of Acute Pancreatitis Study, patients with contrast-enhanced computerized tomography performed were selected (n=129). Serum hematocrit, creatinine, and urea nitrogen on admission and peak values within 48 h of admission were analyzed. The volume of intravenous fluid resuscitation was calculated for each patient.
Of 129 patients, 35 (27%) had evidence of pancreatic necrosis. Receiver operating characteristic curves for pancreatic necrosis revealed an area under the curve of 0.79 for admission hematocrit, 0.77 for peak creatinine, and 0.72 for peak urea nitrogen. Binary logistic regression yielded that all three tests were significantly associated with pancreatic necrosis (P<0.0001), with the highest odds ratio, 34.5, for peak creatinine. The volume of intravenous fluid resuscitation was similar in patients with and without necrosis. Low admission hematocrit (< or =44.8%) yielded a negative predictive value of 89%; elevated peak creatinine (>1.8 mg/dl) within 48 h yielded a positive predictive value of 93%.
We confirm that a low admission hematocrit indicates a low risk of pancreatic necrosis (PNec) in patients with acute pancreatitis. In contrast, an increase in creatinine within the first 48 h is strongly associated with the development of PNec. This finding may have important clinical implications and warrants further investigation.

    ABSTRACT: The incidence of acute pancreatitis (AP) is increasing. AP is one of the gastrointestinal diseases that most frequently requires hospital admission in affected individuals. In the last few years, considerable scientific evidence has led to substantial changes in the medical and surgical treatment of this disease. New knowledge of the physiopathology of AP indicates that its severity is influenced by its systemic effects (organ failure), especially if the disease is persistent, and also by local complications (fluid collections or necrosis), especially if these become infected. Treatment should be personalized and depends on the patient's clinical status, the location of the necrosis, and disease stage.

    ABSTRACT: Acute pancreatitis remains a clinical challenge, despite an exponential increase in our knowledge of its complex pathophysiological changes. Early fluid therapy is the cornerstone of treatment and is universally recommended; however, there is a lack of consensus regarding the type, rate, amount and end points of fluid replacement. Further confusion is added with the newer studies reporting better results with controlled fluid therapy. This review focuses on the pathophysiology of fluid depletion in acute pancreatitis, as well as the rationale for fluid replacement, the type, optimal amount, rate of infusion and monitoring of such patients. The basic goal of fluid epletion should be to prevent or minimize the systemic response to inflammatory markers. For this review, various studies and reviews were critically evaluated, along with authors' recommendations, for predicted severe or severe pancreatitis based on the available evidence.

    ABSTRACT: Abstract None of the definitions of severity used in acute pancreatitis (AP) is ideal. Many of the scoring systems used to predict and measure its severity are complex, cumbersome and inaccurate. Aim to evaluate the usefulness of the most commonly used early markers for predicting severity, necrosis and mortality in patients with AP, and the need for surgery or Intensive Care Unit (ICU) admission. Material&methods Prospective study was performed from March 2009 to August 2010 based on patients diagnosed with AP seen consecutively at a secondary hospital. The early prognostic markers used were Apache II score ≥8 and Ranson’s score ≥3, RCP>120mg/l and Ht>44% in the first 24 hours. Results 131 patients were prospectively enrolled. Median age was 63 years, 60% were men. The most frequent etiology of AP was biliary (68%). Fifteen patients were admitted to the ICU (11.6%) and five (3.9%) required surgery. Twelve patients (9.2%) had necrosis on CT. Four patients (3%) died, all of them in the Severe AP group. Only hematocrit>44 was predictor of mortality in univariate analysis. Conclusion hematocrit ≥ 44% was a significant predictor of mortality. The other indicators present limitations for predicting severity, necrosis and mortality, especially in the first 24 hours.
