Multisystem inflammatory syndrome in children
Overview
Board takeaway: Suspected MIS-C needs prompt medical assessment; emergency signs require emergency services and elective dental care is deferred.
What is multisystem inflammatory syndrome in children?
MIS-C is a rare but serious inflammatory illness associated with SARS-CoV-2 infection, often developing weeks after infection. It can involve the heart, gastrointestinal tract, skin, eyes, blood, and other systems. Hospital surveillance criteria are not a substitute for clinical assessment of a sick child.
Which findings should raise concern for MIS-C?
Ongoing fever with abdominal pain, vomiting or diarrhea, rash, red eyes, dizziness, or substantial lethargy warrants prompt medical contact. Cardiac dysfunction, coronary involvement, and shock can occur. Respiratory symptoms need assessment even when gastrointestinal and mucocutaneous findings predominate.
What oral findings can occur in MIS-C?
Red or cracked lips, oral mucosal erythema, and a strawberry tongue may resemble Kawasaki disease. Oral findings are nonspecific and must be interpreted with systemic symptoms. Pale, gray, or blue lips may signal compromised circulation or oxygenation rather than a local oral lesion.
What should the dental team do if MIS-C is suspected?
Stop elective treatment and arrange prompt medical assessment. Trouble breathing, persistent chest pain or pressure, new confusion, inability to wake, severe abdominal pain, or pale/gray/blue skin or lips requires emergency care. Do not wait for a formal case-definition checklist before escalating an unstable child.
How should dental care resume after MIS-C?
Confirm recovery and residual cardiac or other organ disease with the medical team. Review antiplatelet or anticoagulant medication, bleeding risk, steroid exposure, and any established adrenal insufficiency. Plan sedation or anesthesia from current cardiopulmonary status. Endocarditis prophylaxis requires a separate indication; prior MIS-C alone does not establish one.
What treatment and prognosis apply to MIS-C?
Hospital treatment may include immune-directed therapy and support for circulation and affected organs. Many children recover with care, but follow-up evaluates persistent cardiac or other complications. The dental plan must respond to documented recovery rather than an assumed fixed waiting interval.
