Spectrum of Multiorgan Dysfunction in Scrub Typhus Infection

Area of Science:

• Infectious Diseases
• Pediatrics
• Tropical Medicine

Background:

• Scrub typhus is a significant cause of febrile illness in tropical regions.
• Multiorgan dysfunction is a serious complication in pediatric febrile illnesses.
• Differentiating scrub typhus from other tropical fevers is crucial for timely management.

Purpose of the Study:

• To determine the clinical spectrum of scrub typhus in hospitalized children.
• To compare the incidence of multiorgan dysfunction in scrub typhus versus other tropical fevers.
• To identify key clinical manifestations associated with pediatric scrub typhus.

Main Methods:

• Prospective cohort study involving children aged 2 months to 14 years with acute undifferentiated fever.
• Comparison of scrub typhus IgM ELISA positive cases with IgM negative controls.
• Detailed fever workup and assessment of mortality and morbidity.

Main Results:

• Scrub typhus was diagnosed in 34% (76/224) of febrile children.
• Significantly higher incidence of multiorgan dysfunction in scrub typhus cases (OR 3.5).
• Increased rates of altered sensorium, seizures, ARDS, renal failure, meningitis, thrombocytopenia, transaminitis, and shock in scrub typhus patients.

Conclusions:

• Pediatric scrub typhus is associated with severe systemic manifestations.
• Hospitalized children with scrub typhus exhibit greater morbidity than those with other febrile illnesses.
• Early diagnosis and management of scrub typhus are vital to prevent severe outcomes.
