Ulinastatin in Severe Acute Pancreatitis

Summary

This study aims to evaluate the effect of ulinastatin in the treatment and prevention of organ failure in severe acute pancreatitis.

Description

About 20% of patients with acute pancreatitis have a severe course, and 10-15% of those with severe acute pancreatitis (SAP) die. Despite improvements in intensive care treatment during past few decades, effective therapies for acute pancreatitis are still limited.

Early deaths (within the first week) due to severe acute pancreatitis are generally caused by massive inflammatory responses which result in multiple organ failure. Although the exact mechanisms which trigger the inflammatory processes are not completely understood, it is generally accepted that autodigestion and activated leukocytes play important roles in the pathogenesis of acute pancreatitis. Activation of digestive enzymes causes pancreatic injury and results in an inflammatory response that is out of proportion to the response of other organs to a similar insult. The acute inflammatory response itself causes substantial tissue damage and may progress beyond the pancreas to a systemic inflammatory response syndrome, multi organ failure, or death.

UTI is a multivalent Kunitz-type serine protease inhibitor that is found in human urine and blood, it can stabilize lysosome membrane and inhibit lysosome function, inhibit the various enzymes and inflammatory response. Previous study proved that it protects against SIRS pathophysiology and subsequent organ damage induced via the modulation of the proinflammatory mediator, as well as chemokines. UTI has been widely used for the treatment and prevention of multiple organ failure in China, but there is few randomized, placebo controlled trial on ulinastatin. A large multicenter, randomized study is warranted. In this study, we aim to evaluate the effect of ulinastatin in the treatment and prevention of organ failure in severe acute pancreatitis with regular treatment in an add-on trial.

Medical and Biotech [MESH] Definitions

INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

C-type lectins that restrict growth of bacteria in the intestinal epithelia and have bactericidal activity against gram-positive and gram-negative bacteria. They also regulate proliferation and differentiation of KERATINOCYTES following injury. Human pancreatitis-associated protein-1 (Reg3a) is overexpressed by pancreatic ACINAR CELLS in patients with CHRONIC PANCREATITIS. It is also highly expressed by pancreatic, bladder, and gastrointestinal cancer cells and may serve as a diagnostic biomarker.

Acute or chronic INFLAMMATION of the PANCREAS due to excessive ALCOHOL DRINKING. Alcoholic pancreatitis usually presents as an acute episode but it is a chronic progressive disease in alcoholics.

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
