BPSU - Juvenile-onset Systemic Lupus Erythematosus (JSLE)

Surveillance of Juvenile-onset Systemic Lupus Erythematosus (JSLE) commenced in September 2017. This study aims to determine the incidence of JSLE in children and young people (CYP) in the UK and Ireland. The data will be analysed to better understand the epidemiology and clinical features of the disease and how children and young people are accessing care.

JSLE or ‘childhood lupus’ is a rare multisystem illness where the immune system attacks many parts of the body. JSLE can be very variable in how it manifests, with some children and young people having a mild disease and others having a very severe disease (e.g. developing kidney failure or brain abnormalities). If it starts in childhood or adolescence it is generally much more severe, and requires more use of steroids and other potent medications which suppress the immune system (immune-suppressant medications) than in adults.

Although we say around 15-20% of cases start in childhood, there is a great lack of strong studies examining the actual number of cases of JSLE in the UK and Republic of Ireland.  This means that the overall burden of illness caused by JSLE is unknown.
