Dengue Myositis: Case report

Abstract

Background: We present a case of 36-year-old man from Bangkok. He had high grade fever for two days, intermittently associated with myalgia, headache with postorbital aching pain, fatigue and vomiting. On physical examination, he was febrile and the others were unremarkable. Diagnosis of dengue fever was confirmed with positive of NS1 antigen. The patient was admitted to hospital for supportive treatment. On the fifth day of hospitalization, the patient was raising his creatinine phosphokinase (CPK) with an absolute value of 832 u/L. The diagnosis was a Dengue myositis. He had improved after receiving symptomatically treatment. The CPK level declined to 183 u/L over next 5 days and the patient was discharged. Conclusion: We reported Dengue myositis which is a rare disease and under-recognized by many physicians. We suggested that patients with Dengue fever should aware for Dengue myositis and checked their serum CPK level for early detection and prevention of rhabdomyolysis.
