Rhabdomyolysis and Dengue Fever: A Case Report and Literature Review

The medical literature contains only a few reports of rhabdomyolysis occurring in patients with dengue fever. We report the case of a 25-year-old Jamaican man who was admitted to a private hospital four days after the onset of an acute febrile illness with fever, myalgia, and generalized weakness. Dengue fever was confirmed with a positive test for the dengue antigen, nonstructural protein 1. He remained well and was discharged on day 6 of his illness. On day 8, he started to pass red urine and was subsequently admitted to the University Hospital of the West Indies. On admission he was found to have myoglobinuria and an elevated creatine phosphokinase (CPK) of 325,600 U/L, leading to a diagnosis of rhabdomyolysis. Dengue IgM was positive. He was treated with aggressive hydration and had close monitoring of his urine output, creatinine, and CPK levels. His hospital course was uneventful without the development of acute renal failure and he was discharged after 14 days in hospital, with a CPK level of 2463 U/L. This case highlights that severe rhabdomyolysis may occur in patients with dengue fever and that early and aggressive treatment may prevent severe complications such as acute renal failure and death.
