During the COVID-19 pandemic, a small minority of children have been presenting to acute paediatric services with a new syndrome, Paediatric Inflammatory Multisystem Syndrome temporally associated with SARS-Cov-2 (PIMS-TS). Children with PIMS-TS present with symptoms of inflammation caused by the immune system going into overdrive - this is likely to be in response to the virus. More severe cases involve inflammation and damage to the heart.
The focus of this project is to identify children with milder forms of PIMS-TS who are at risk of progression to more severe disease. Being able to predict the disease course of PIMS-TS at an early stage is important as it will allow clinicians to decide which patients should be treated with immunosuppressants, which have been shown to reduce the severity of the illness but have side effects.
Early data suggests that children with PIMS-TS have elevated biomarkers associated with an over-reaction of the body's immune system (also known as a 'cytokine storm') reaction. This study will explore whether children presenting with milder PIMS-TS have elevated 'cytokine storm' blood profiles and whether these profiles differ between children who continue to have a mild disease course compared to those who develop severe disease.
During the COVID-19 pandemic a minority of children have presented to acute services with clinical features of a new syndrome known as Paediatric Inflammatory Multisystem Syndrome temporally associated with SARS-Cov-2 (PIMS-TS). This high inflammatory state, likely triggered by the virus, has overlapping features of Kawasaki's and Toxic Shock Syndrome.
The focus of this study is to identify which children presenting with mild PIMS-TS symptoms will go on to develop severe disease requiring intensive care unit (ICU) admission. This is important as data suggests that early aggressive treatment with immunosuppression can lead to a relatively quick resolution in symptoms. The results of this study could allow clinicians to be selective in treating patients in whom the benefits of treatment outweigh the risks.
Early data suggests a 'cytokine storm' is involved in the PIMS-TS disease process. This proposed observational study will investigate whether children presenting to the non-ICU setting with features of PIMS-TS have raised cytokine storm biomarkers and whether these may be used to predict which children go onto develop severe disease.
The proposed study will include up to 15 hospitals across East of England. NHS clinical care teams will identify patients meeting the inclusion criteria and upload anonymised data into a secure web-based study database. Data will be retrieved for retrospective cases from 1st March 2020 and prospective data entered up until September 2021.
One hundred children presenting to acute (non-ICU) paediatric services with symptoms of PIMS-TS during the study period will be included.
The primary objective of the study is to describe the 'cytokine storm' biomarker profiles of children aged between 3 months to 16 years presenting with PIMS-TS to the non-ICU setting, focussing on those biomarkers which are readily accessible to district general hospitals (Pro-Beta Natriuretic peptide [BNP], ferritin, and CRP).
The secondary aims of the study are to:
