In this report, we discuss a case series of severe leptospirosis with pancreatitis as a main complication during an unusual outbreak of leptospirosis in Anuradhapura district, Sri Lanka.,We retrospectively reviewed clinical presentation, investigations, treatment and outcome of six confirmed cases of severe leptospirosis admitted to intensive care unit (ICU) of Teaching Hospital, Anuradhapura, within a three months period from November 2014 to January 2015. All six patients were previously healthy paddy farmers presented with fever, myalgia and arthralgia. Four patients had abdominal pain, nausea and vomiting on admission. Hypotension, Neutrophilic leukocytosis and thrombocytopaenia was detected in all patients in the initial stage. Four patients had serum amylase more than 900 (range 941-2420).
