Background:

A large multicentre multinational inception cohort was established to study risk factors for atherosclerosis (AS) in SLE. This study describes survival, mortality and causes of death during the first 10 years of observation of the SLICC inception cohort.

Methods:

Patients enter the cohort within 15 months of SLE diagnosis (>=4 ACR criteria). Clinical and laboratory features of SLE and comorbidities are gathered in a standardized protocol at yearly intervals. Deaths are recorded as they occur and the cause of death is determined according to the ICD9 code. Demographic and disease related factors present at enrolment were compared in patients who died and in survivors using descriptive statistics, Kaplan-Meier curve as well as life table analysis.

Results:

Since 2000, 1593 patients have been entered into the cohort (89.4%F, age at SLE 34.6y, mean followup of 3.7 years). 30 patients have died during the course of follow-up. Survival was 99.6% at 1 year, 98.4% at 3 years and 97.5% at 5 years (figure 1)

Causes of death included coronary artery disease (CAD) in 7, SLE in 9, infection in 9, 1 from other causes and 4 unknown. Patients who died were older at diagnosis, more often had CAD, and had higher SLICC/ACR damage index scores at enrolment and a decreased physical components score (PCS) of the SF-36 at enrolment. Patients who died were also more likely to have used corticosteroids (HR=6.4 p=0.01) and immunosuppressives(HR=2.4 p=0.02) and less likely to have used antimalarials(HR=0.3 p=0.001) at enrolment.

Conclusion:

This multinational inception cohort of SLE patients demonstrates the improved survival noted among patients with SLE. Causes of death in the first 10 years of observation of the SLICC inception cohort with an average followup of 3.7 years include CAD, SLE and sepsis. Even early on in the course of SLE, CAD is an important cause of death. Older age, history of CAD, early damage and impaired physical function, use of corticosteroids and immunosuppressives are associated with mortality.
