Study of Virus-specific Lymphocytic Cell Populations in Non-invasive Nasal Mucosa Samples of MIS-C Patients

Recruiting
Conditions
MIS-C Associated With COVID-19
COVID-19
Registration Number
NCT05560906
Lead Sponsor
Medical University of Warsaw
Brief Summary

The aim of the study is to make an accurate assessment of immune cells obtained from nasal mucosa and peripherial blood of MIS-C patients during the disease and the period of health.

Detailed Description

The study will consist of two parts. Initially, it will be of a cross-cutting comparative nature, when a group of healthy patients (control group) and a group of patients diagnosed with MIS-C/PIMS syndrome are compared with each other, based on nasal curettage swabs and peripheral blood, before the inclusion of systemic anti-inflammatory treatment (study group). In addition, an observation of the research group will be carried out, during which swabs and peripheral blood will be taken at two more control points.

Primary Outcome Measures
NameTimeMethod
Change in leukocyte subpopulations in nasal mucosa and peripherial blood during MIS-C and convalescence.Three clinical timepoints: (i) baseline (preferably before immunomodulatory treatment), (ii) convalescence, after major symptoms resolution (1 week +/-2 days after treatment introduction), (iii) outpatient control visit (6 weeks after hospital discharge)

The cellular subpopulations will be characterized and clustered using prepared immunomarker array.
