Acute Onset Hypokalemic Quadriparesis with Dengue Fever: A Case Report.

ABSTRACT

Dengue fever is an acute viral disease caused by dengue virus (DENV1- 4) and is endemic to India. It commonly presents as fever along with headache, bodyache, rashes, polyserositis, bleeding manifestations and rarely as cardiovascular, gastrointestinal, renal or neurological manifestations. Here, we report a case of dengue fever with hypokalemic quadriparesis. A 38-year-old male admitted with history of fever of 3-day duration and weakness of all four limbs of 1-day duration. His investigations showed Hb - 16.20 g/dL, platelet - 37,000/mm3, serum Na+ - 150.00 mmol/L, serum K+ - 2.50 mmol/L and positive dengue serology. Hypokalemic quadriparesis secondary to dengue fever should be considered as a differential diagnosis in a case of acute febrile illness with muscle weakness in tropical countries.
