Insights
Bacterial sepsis co-infection in dengue fever affects over 10% of pediatric patients, particularly young children. Early sepsis screening and antibiotics are crucial for severe dengue cases, especially those in shock.
Area of Science:
- Infectious Diseases
- Pediatrics
- Critical Care Medicine
Background:
- Dengue fever is a prevalent arthropod-borne viral illness globally.
- Concurrent bacterial sepsis in dengue fever patients is an underrecognized complication.
- Understanding sepsis risk factors in dengue is critical for patient management.
Purpose of the Study:
- To investigate the incidence and characteristics of bacterial sepsis in children with dengue fever.
- To identify clinical indicators associated with sepsis in pediatric dengue patients.
Main Methods:
- Retrospective cohort study involving 124 pediatric patients (3 months to 18 years) with dengue fever.
- Analysis of patient demographics, clinical presentation, hospital stay, and laboratory markers, including PCT.
- Comparison of characteristics between dengue patients with and without concurrent sepsis.
Main Results:
- The incidence of concurrent sepsis in pediatric dengue patients was 10.4% (13/124).
- Sepsis was more common in children aged 0-5 years (53.8%) and associated with longer hospital stays (53.8%), shock (76.9%), and elevated PCT (100%).
- Blood cultures were positive in 5 out of 13 sepsis cases.
Conclusions:
- Young children with dengue fever, especially those presenting with shock, are at higher risk for sepsis.
- Elevated procalcitonin (PCT) is a significant indicator of sepsis in dengue patients.
- Routine antibiotic use in dengue is not recommended, but early sepsis screening and treatment are vital for high-risk pediatric cases.
Abstract:
Dengue fever is the most common arthropod borne infection worldwide. Bacterial sepsis in dengue fever is not widely recognised. This is a retrospective cohort study of children who had sepsis coexisting along with Dengue fever. One hundred and twenty-four patients aged between three months and eighteen years admitted in two private hospitals in North India were studied. Thirteen children had concurrent sepsis (13/124, 10.4%). Children between 0 and five years (7/13, 53.8%, p = 0.019), having longer hospital stay (7/13, 53.8%, p = 0.00029), shock (10/13, 76.9%, p = 0.00001), and increased PCT (13/13, 100%, p < 0.001) were some indicators of sepsis in these patients. Blood cultures were positive in five children. It is a matter of speculation as to why these patients of dengue are more susceptible to sepsis. Increased vascular permeability may increase the chances of bacterial contamination. Antibiotics should not be used routinely in dengue fever. However, young children presenting with severe symptoms especially shock should be screened for sepsis, and appropriate antibiotics should be started early.
