Hemorrhagic Fever with Renal Syndrome Complicated with Acute Pancreatitis and Capillary Cholangitis: A Case Report.

Hemorrhagic fever with renal syndrome (HFRS), caused by hanta viruses (HTNV), can be complicated by severe complications. Seventeen percent of the HFRS patients with abdominal pain had acute pancreatitis (AP). The reported prevalence of AP among HFRS patients has a conspicuous high mortality rate. Of note, acute capillary cholangitis (ACC) among HFRS patients presenting with abdominal pain appears extremely rare, particularly independent of HFRS patients complicated with AP. The main pathophysiological mechanism of HFRS complicated with AP and ACC may be that it preferentially damages the microvascular and induces plasma leakage. To date, the management of severe HFRS cases is mainly based on supportive treatment, including extracorporeal blood purification and mechanical ventilation. Here, we describe an exceptionally rare case of a 34-year man who developed HFRS with AP and ACC while improving from HTNV infection via antiviral and supportive treatment.
