Study summary

SLE disease in Saudi Arabia is yet not well defined especially in a population with high consanguinity and high inbreeding coefficient . Up until now, there has been no prospective cohort study for SLE patients in Saudi Arabia. As a result, current published literature is focused on retrospective chart reviews which are subjected to many forms of bias. so the investigator proposed this prospective registry which will follow open cohort study design aiming to provide better understanding of disease presentation, course and outcomes especially if complemented by detailed immunological, molecular, genetic and microbiome data.
