Acute pancreatitis following kidney transplantation – role of viral infections

: Acute pancreatitis following renal transplantation is an unusual complication that carries a high mortality. Over the last 10 yr, five of 185 patients at our center developed acute pancreatitis. All had live related donors and were on conventional triple drug immunosuppression. Pancreatitis was classified according to the computed tomography scan based on Atlanta Classification. All five patients who developed acute pancreatitis had evidence of symptomatic or serologically active viral infection (chicken pox in two, cytomegalovirus infection in two, hepatitis E virus in one) and no patient without viral infection developed pancreatitis. Overall, 45 patients developed symptomatic or serologically active viral infection. There was a significant association between viral infection and pancreatitis (chi-square test, p < 0.001). Three patients with severe acute pancreatitis died while both patients with mild pancreatitis survived. An active search for viral infections should be made in all patients with acute pancreatitis. Specific antiviral measures may help reduce the mortality of acute pancreatitis in these patients. Consideration must be given to varicella immunization in patients with renal failure.
