Imunomodulation in Acute Pancreatitis- How Can Cytokines, B and T Cells Predict the Outcome of the Disease

Acute pancreatitis is an acute inflammatory pathology of the pancreas with activation of both innate and adaptive immune system, including T and B lymphocytes and release of inflammatory cytokines. We aim to characterize the circulating profile of T and B cells, its regulatory populations and B cell maturation, as well as inflammatory cytokines, in a prospective way of 50 patients with acute pancreatitis admitted to Hospital da Luz Lisboa. Blood samples will be collected at hospital admission, 48h, one month and 6 months after hospitalization of patients, relating these values to the severity of acute pancreatitis. Patients with acute pancreatitis in the previous 6 months, diabetes mellitus, pregnant women, uncontrolled comorbidity and terminal neoplasms will be excluded. A control group of 30 ambulatory individuals observed at the Hospital da Luz Lisboa will be recruited. Laboratory evaluation will be performed at the Immunology Laboratory of NOVA Medical School.
