Dengue Infection Induced Diffuse Alveolar Hemorrhage

[摘要] Background: Dengue fever is a commonly encountered arthropod-borne viral disease. The spectrum of the disease varies widely, and at times it may present with unusual complications. One such dreaded but rare complication is diffuse alveolar hemorrhage (DAH). Case Report: A 42 years old lady having no co-morbidities presented with dengue infection. The presentation included fever, gum bleed, and asthenia. The examination showed low oxygen saturation and clear chest. The discordance between clinical findings and the oxygen saturation led to a cascade of investigations, culminating in the diagnosis of DAH. She was managed symptomatically, with full recovery. Conclusion: DAH is an uncommon, life-threatening, complication of dengue infection. A high index of suspicion, prompt evaluation and early institution of appropriate therapy hold the key to successfully manage such patients.
