Abstract
Myalgia is a common symptom in patients with Dengue fever. However, acute rhabdomyolysis is a rare manifestation. The precise mechanism of Dengue-associated rhabdomyolysis has not been determined, it is thought likely to be caused by myotoxic cytokines released in response to viral infection, such as TNF and IFN-α. Here we report a case of a 13-year-old boy with Dengue fever, presenting with red urine on day 5 of illness. Together with a decreased platelet count (26 G/L), we initially suspected hematuria but the urinalysis showed no red blood cells. We then thought of rhabdomyolysis causing myoglobinuria, so we ordered diagnostic tests with the following results: CK 1353 U/L, GOT 361 U/L, GPT 90 U/L. The patient was given intravenous fluids and oral oresol to control urine output. Urine color faded and blood CK concentration returned to normal after 13 days. Rhabdomyolysis is rare in dengue fever but requires proper diagnosis and management to prevent acute kidney injury - a life-threatening complication.
