A Haemophilic Dengue Patient with Pleural Effusion and Earache.

About 2.5 billion people are living at a higher risk of dengue fever in hundreds of tropical and sub-tropical countries. Treatment of dengue fever is quite complicated and challenging because of the lack of effective treatment approaches. We herein report a rare case of a 25-year-old female with a past medical history of haemophilia A, suffering from dengue fever, pleural effusion, earache, myalgia, headache, and vomiting. Dengue was confirmed by the non-structural protein 1 (NS1) antigen and immunoglobulin M (IgM) antibody test. She had low blood pressure (80/60 mmHg), frequent vomiting, and low platelet count during hospitalization. Moreover, a genetic disorder like haemophilia with plasma leakage and earache made the patient's condition worse. However, by repeated platelet infusion, the platelet counts elevated and the patient was discharged from the hospital after nine days. Complete recovery was achieved after 27 days. This is a rare case of dengue; physicians should be aware of the severity of the disease and its management tactics. More discussion and research need to be carried out to develop an effective and optimized treatment and management options to reduce the mortality and morbidity due to dengue fever with a co-morbid disease.
