Summary
Distinguishing Multisystem Inflammatory Syndrome in Children (MIS-C) from dengue in febrile children is crucial. Mucocutaneous features and high CRP suggest MIS-C, while petechiae and hepatomegaly may indicate dengue.
Area of Science:
- Pediatrics
- Infectious Diseases
- Immunology
Background:
- Multisystem Inflammatory Syndrome in Children (MIS-C) presents with overlapping symptoms to other febrile illnesses, complicating early diagnosis.
- Differentiating MIS-C from locally prevalent diseases like dengue is essential for timely and appropriate management.
Purpose of the Study:
- To compare the clinical and laboratory profiles of children admitted with MIS-C and dengue.
- To identify key features that can help distinguish between MIS-C and dengue at the onset of illness.
Main Methods:
- A retrospective study was conducted on children aged 12 years or younger admitted with either MIS-C (WHO definition) or laboratory-confirmed dengue.
- Data was collected from August 2020 to January 2021 at a tertiary care center in North India.
Main Results:
- Eighty-four children (40 MIS-C, 44 dengue) were analyzed. MIS-C cases more frequently exhibited rash, conjunctival injection, oral mucocutaneous changes, and gallop rhythm.
- Dengue cases were more associated with petechiae, myalgia, headache, and hepatomegaly. Significantly higher C-reactive protein and interleukin-6 levels were observed in MIS-C.
- Dengue patients showed higher hemoglobin, lower platelet counts, and greater elevation in aspartate and alanine aminotransferases. Hospital stay was longer for MIS-C, but PICU stay and mortality were comparable.
Conclusions:
- Mucocutaneous manifestations and significantly elevated C-reactive protein levels can help differentiate MIS-C from dengue in hospitalized children with acute febrile illness.
- The presence of petechiae, hepatomegaly, and hemoconcentration may suggest a diagnosis of dengue over MIS-C.
