Background: Dengue is globally the most common arboviral disease. As the primary immunopathological target in dengue is the endothelium, presentations beyond the typical triad of fever, myalgias, and thrombocytopenia are increasingly encountered. Severe systemic organ involvement can occur even without evidence of dengue hemorrhagic fever (DHF). These manifestations of dengue have been termed the “expanded dengue syndrome” by WHO. Aim: To observe the types and frequency of organ involvement in patients admitted with acute dengue fever. Methods: This is a retrospective cross-sectional study. Records of patients above 18 years admitted with acute dengue fever from December 2016 to December 2017 were reviewed. Patients fulfilling WHO criteria for probable or confirmed acute dengue fever were included. Patients with definite laboratory evidence of other systemic infections and patients with autoimmune or hematological disease were excluded. Data were obtained for 129 patients and analyzed using IBM-SPSS-21. Frequencies of clinical manifestations and organ involvement were noted. Results: Gastrointestinal manifestations occurred in 89% of patients. Transaminitis, organomegaly, and serositis were common. About 19% had pulmonary involvement, and 9% of patients had neurological features. Renal dysfunction, dyselectrolytemia, ophthalmic, muscular, and lymphoreticular abnormalities were also seen. Conclusion: Systemic involvement in dengue is not uncommon, and organ dysfunction can occur in the absence of severe DHF. Recognition of myriad range of organ involvement is crucial for optimal management.
