RESUMO
Objectives: In 2022, Bangladesh had the highest dengue-related fatality (281). This study evaluated clinical profiles to detect early changes to predict dengue fever severity. Methods: This prospective observational study was performed in four government hospitals from June to November 2022 in Dhaka. Febrile patients admitted within 4th day of illness were recruited if they had a confirmed dengue viral infection either by by positive dengue nonstructural protein antigen or anti-dengue immunoglobulin (Ig)M antibody. Results: We divided 308 patients with confirmed dengue into two groups: 232 (74.3%) in nonsevere dengue and 76 (24.7%) in severe dengue. Men were 205 (66.6%), and the most affected age group was 21-30 years (47.7%). Patients with severe dengue reported a higher number of nausea 80.3%, coughs 57.9%, abdominal pain 56.6%, persistent vomitting 53.9%, dyspnea 35.5%, diarrhea 28.9%, and skin rash at 27.6%. In addition, the disease's febrile phase (≤4 days) showed thrombocytopenia (odds ratio [OR] 6.409, 95% CI 2.855-14.386, p <0.001), hemoconcentration (OR 3.428, 95% CI 1.030-11.405, p 0.045), and hypotension (OR 5.896, 95% CI 1.203-28.897, p 0.029) were associated severe disease. Conclusions: Hypotension, thrombocytopenia, and hemoconcentration during the febrile phase might indicate progression towards severe disease.
RESUMO
Dengue represents one of the most dangerous mosquito-borne viral diseases. Although the disease has been prevalent around the globe over the centuries, recent outbreaks of dengue have devasted the healthcare delivery system of many countries. Being a global infection, dengue virus (DENV) is endemically present mainly in Latin America and Caribbean countries as well as countries in South Asia. The recent outbreak of DENV infection has indicated an exceptional outbreak of DENV in some countries in South Asia. There has been a serious endemic of DENV during 2019. After a heterogeneous pause, another severe outbreak of DENV was reported in some Asian countries in 2023. Among the Asian countries, Bangladesh has reported an acute upsurge of DENV infection in 2023 with record numbers of fatalities. However, this pattern of DENV has not been detected in neighbors of Bangladesh, such as India or other countries in Southeast Asia. This provides an emergent task of dissecting the present DENV infection in Bangladesh from different angles to get insights for future containment of the DENV infection, not only in Bangladesh but also in other DENV endemic areas or DENV-native areas.
