Dengue hemorrhagic fever complicated with transient diabetic ketoacidosis: a case report.

BACKGROUND: The increasing global prevalence of both dengue and diabetes may warrant closer observation for glycemic control and adapted fluid management to diminish the risk for a severe clinical presentation of dengue. Dengue illness is rarely known to precipitate diabetic ketoacidosis among diabetic patients. Both type 1 and type 2 diabetes increase the release of pro-inflammatory cytokines by various mechanisms and increase the risk of plasma leak in dengue fever. Acute pancreatitis is an atypical and rare presentation of dengue fever. We report a case of transient diabetic ketoacidosis in a previously well man which was challenging for the treating physician.

CASE PRESENTATION: A 26-year-old previously healthy Sri Lankan Sinhalese man presented to hospital with dengue hemorrhagic fever in compensated shock. He was found to have diabetic ketoacidosis and was managed with hydration and insulin infusion. Following recovery from dengue shock, his sugars normalized and ketogenesis stopped without exogenous insulin.

CONCLUSIONS: Transient hyperglycemia with ketoacidosis, such as in our patient, has not been reported in the literature. Dengue virus inducing a transient pancreatitis during the viremic phase, however, is a possibility.
