Abstract
Backgrounds: The COVID-19 pandemic has brought numerous challenges. One of them is multisystem
inflammatory syndrome in children (MIS-C), developing two to six weeks after acute SARS-CoV-2
infection. This study aimed to describe the clinical characteristics of patients who met the criteria for MIS-
C, and compare them with the features of Kawasaki disease (KD) and toxic shock syndrome (TSS).
Methods: This retrospective study was conducted at the Children's Clinical University Hospital in Riga,
Latvia, and involved children with MIS-C, KD or TSS. Clinical data was collected from medical records and analysed using descriptive
parametric and non-parametric statistics. A statistically significant difference between groups was
assumed where p value Results: In all, 81 children were included in the study: 39 (48.1%) with KD (mean age 3.9 (SD 3.7) years;
23 boys (59%)), 29 (35.8%) with MIS-C (mean age 9.8 (SD 4.5) years; 16 boys (55.2%)) and 13 (16.1%)
with TSS (mean age 11.3 (SD 5.2) years; 5 boys (38.5%)). The time from symptom onset to diagnosis
was shorter in TSS compared with MIS-C and KD (pKD, with more frequent gastrointestinal symptoms (e.g., abdominal pain, vomitting, diarrhoea),
neurological manifestations (e.g., headache, meningism/photophobia, hyperaesthesia) and cardiac
involvement at onset (i.e., valvular insufficiency, pericardial effusions, systolic dysfunction)(pMeanwhile, cervical lymphadenopathy, synovitis and arthralgia were significantly more common in KD
compared with MIS-C and TSS (pConclusions/Learning Points: Children with MIS-C display specific clinical features when compared
with those with KD and TSS. The overlapping signs and symptoms of these childhood diseases make an
appropriate diagnosis challenging.
