Plain English Summary

Background and study aims
Paediatricians worldwide are seeing rapidly increasing numbers of children with a wide spectrum of inflammatory syndromes temporally associated with the SARS-CoV-2 (COVID-19) pandemic. These emerging disorders appear to represent unusual responses to COVID-19 driven by children’s immune systems, with overlapping features with Kawasaki Disease (KD), a rare paediatric inflammatory disorder.
Currently, paediatricians around the world are managing these patients with treatments that they judge to be best for their patients with the resources they have available; these include a range of anti-inflammatory and immunomodulatory treatments. Furthermore, many centres will not have certain treatments available due to a worldwide shortage of many agents as a result of their use in COVID-19 patients. This has raised urgent questions for children, families and their clinicians, including: are there clinical or blood markers which predict disease severity? Do the available anti-inflammatory and immunomodulatory treatments improve the outcomes including reducing the risk of coronary artery aneurysms? What are the risks and benefits of these treatments? What is the risk of long-term complications, e.g. coronary artery aneurysm, and how does this relate to syndrome and severity?
The aim of this study is to collect anonymised data on all patients with this emerging condition using an online case report form. Capturing the patient’s clinical findings, inflammatory markers, treatments and outcomes will allow a careful analysis of these data to advance the understanding of these disorders and their complications and rapidly provide answers on the questions as to which patients to treat, which treatments work and which may be harmful.

Who can participate?
Clinicians from across the world are welcome to join the study and enrol any patient with a suspected inflammatory condition associated with SARS-CoV-2 onto the online database. Detailed inclusion criteria will be sent to prospective project partners.

What does the study involve?
The study involves the collection of non-identifiable routinely collected clinical data on confirmed or suspected cases of a new inflammatory syndrome associated with COVID-19 from across the UK and globally. A secure online database system (REDCap) will be used for data collection. If a centre wants to take part in the study, they will nominate a lead for their institution, who will be provided with an individual REDCap account and a user guide for entering data onto the REDCap database. Doctors caring for patients in emergency departments, wards or intensive care units will identify patients meeting the study criteria. The relevant patients can then be enrolled onto the REDCap database and data entered retrospectively. Data will then be analysed by the study management team to address the primary and secondary objectives.

What are the possible benefits and risks of participating?
Each clinical site that joins the study will become part of an international “BATS consortium” and the data submitted to the online database will be used to address essential questions regarding a new inflammatory syndrome associated with COVID-19. Project partners will have access to records entered from their site only. There are no risks involved with participating.

Where is the study run from?
Imperial College London (UK)

When is the study starting and how long is it expected to run for?
May 2020 to November 2024

Study acronymBATS
Study hypothesisAdministration of drugs to regulate or suppress the immune system (immunomodulators, e.g. immunoglobulin, steroids, anti-TNF, IL1-inhibitors, IL6- inhibitors, ciclosporin) will result in more rapid resolution of fever and inflammation, prevent disease progression, reduce the need for intensive care or organ support and reduce the risk of children developing coronary artery aneurysms and other long-term complications.

ConditionA spectrum of new inflammatory syndromes associated with COVID-19 (SARS-CoV-2 infection)
InterventionThe researchers will study routinely collected non-identifiable data from patients presenting to hospitals worldwide with clearly defined clinical phenotypes.

Study size:
The researchers anticipate recruitment of at least 1800 in total (150 cases from the UK, 50 from the host site). In the last month, since the establishment of a case definition in the UK (RCPCH 1 May 2020), over 100 cases have been reported across the UK and numbers are continuing to rise.

Recruitment process:
Study information including clear guidance on which patients to enrol on the database and how to use the database will be disseminated across UK NHS hospital and internationally, through existing consortia and collaborations as well as international societies. If a centre wants to take part in the study, they will nominate a lead for their institution, who will be provided with user log-in details and a user guide for entering data onto the REDCap database. Paediatric doctors caring for children in emergency departments, wards or intensive care units will identify patients meeting the study criteria. The relevant patients can then be enrolled onto the REDCap database and data entered retrospectively.

Collection of clinical data:
Data will be collected systematically on any patients meeting the study criteria using an online case report form. Patients will be anonymised and identified only by the clinician reporting the case. The severity of each patient’s clinical findings, inflammatory markers and organ dysfunction will be recorded on a daily basis before and after initiation of immunomodulating agents, or during observation (if no specific treatment given). Outcomes including, time in intensive care units, duration of organ support, or death along with the presence of coronary artery aneurysms and any other long term complications will be recorded.

Clinical data recorded for routine clinical care will be entered retrospectively onto the database. There will be no follow up. The database will be open for 2 years for data entry.
Intervention typeOther
Primary outcome measureCurrent primary outcome measures as of 08/04/2021:
