Study of Pulmonary Manifestations among Dengue Patients in Tertiary Care Hospital of North India

ABSTRACT

Introduction: Thoracic manifestations such as pleuraleffusion, pneumonia, and haemoptysis have been reportedin dengue infection. Dengue haemorrhagic fever (DHF) canresult in acute respiratory distress syndrome. Dengue shocksyndrome (DSS) is reported to be the third leading cause ofARDs in dengue endemic area. Current research aimed tostudy pulmonary manifestations among dengue hospitalizedpatients.Material and Methods: This study was conducted in 50patients of dengue confirmed by dengue serology. Respiratorymanifestations were recorded and all clinical examinationfindings were recovered. Baseline investigations includingcomplete blood count, liver profile, renal profile, arterial bloodgas analysis, dengue virus IgM and IgG and ns1 antigen, chestx-ray, ultrasound thorax and abdomen ultrasonography weredone.Results: Young age patients and patients with co-morbidityare risky to severe form of dengue fever and have a high riskof death. As regards co-morbidities, chronic chest disease andcardiac disease are mostly vulnerable to Dengue HaemorrhagicFever and Dengue Shock Syndrome. The most presentingrespiratory manifestations were Acute Respiratory DistressSyndrome followed by pneumonitis and pleural effusion.Conclusion: Incidence of pulmonary complications amongcases of Dengue is quite high and therefore can be used asan indicator of serious presentation of dengue in the patients.
