This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
Clinicians observed a cluster of children with unexplained inflammation requiring admission to United Kingdom (UK) paediatric intensive care units (PICUs) in April 2020. Despite multiple guidelines, which treatments are effective in Paediatric Inflammatory Multisystem Syndrome Temporally associated with SARS-CoV-2 (PIMS-TS) is unknown.Methods:
Multicentre observational study of children (<18 years) admitted to UK PICUs between 1 April and 10 May 2020, fulfilling the case definition of PIMS-TS. Routinely collected, de-identified data was analysed. Linear mixed effects models were used to analyse the effect of steroids, intravenous immunoglobulin (IVIG), and biologic agents on C-reactive protein (CRP), platelet counts,and lymphocyte counts. The content of UK clinical guidelines was collated.Findings:
Over the six week study period 59/78 (76%) children received IVIG, 57/78 (73%) steroids, and 17/78 (22%) a biologic agent. We found no evidence of a difference in response in clinical markers of inflammation between patients with PIMS-TS who were treated with IVIG, steroids or biologics, compared to those who were not. Despite a progression to near universal treatment with immunomodulators, the proportion of patients with coronary artery abnormalities increased. Guidelines universally advised or considered the use of IVIG, steroids, and biologics.Interpretation:
We were unable to identify any short term benefit from any of the treatments, or treatment combinations administered. Despite a lack of evidence, worldwide treatment guidelines for PIMS-TS have become very similar. Clinicians treating PIMS-TS should continue to have equipoise and participate in robust clinical trials of all treatments currently being utilised for this important condition.Funding:
NoneDeclaration of Interests All authors have completed the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest, and have no conflicts of interest to disclose.Ethics Approval Statement The project was classified as a service evaluation by the Nottingham Research and Innovation team (Nottingham Clinical Effectiveness Team ref 20- 235C), and ethics approval was not required. The study team analysed routinely collected de-identified data submitted by clinicians from the individual PICUs as a local service evaluation. Clinicians obtained informed parental consent if required locally.
