Is Lymphocyte Subtype Important for Acute Pancreatitis Severity?

Pancreatitis is a common complication especially in patients with gallbladder stones, most patients with biliary pancreatitis may recover spontaneously without sequelae, but in 10-20% of patients, the disease is severe and mortality rates of up to 30% are detected in these patients. In patients with severe pancreatitis, aggressive fluid replacement, organ damage follow-up, appropriate antibiotherapy, and endoscopic sphincterotomy and radiological interventions may be of great benefit. In the evaluation of acute biliary pancreatitis, many scoring systems have been established (Atlanta, Ranson, APACHE, BISAP etc.) from past to present to determine morbidity and mortality of the disease. There are limited number of studies in the literature about the immune parameters in the evaluation of acute pancreatitis. In a studies, serum inflammatory markers such as IL-1, IL-6 and CD4, CD8 T lymphocyte and Treg population were evaluated.Treg cells are reported to be an independent prognostic factor in determining the severity of acute pancreatitis. In patients diagnosed with acute biliary pancreatitis, determination of the course of the disease at the time of diagnosis is extremely important for treatment and survival. In this study, the investigators aimed to evaluate the correlation between morbidity and mortality of acute biliary pancreatitis with lymphocyte subtypes via Flow-cytometry.
