Abstract

Background and objective: East Asian systemic lupus erythematosus (SLE) is under represented in lupus cohorts outside of East Asia. We asked whether lupus nephritis was more common and more severe in East Asians than in other ethnicities in a large United States SLE cohort.

Methods: The Hopkins Lupus Cohort, a longitudinal cohort of 2802 patients (53.5% Caucasian, 39.2% African-American, 3.2% East Asian) was studied. The SLICC/ACR Damage Index was used to assess renal outcomes. Results: East Asian patients had the same prevalence of lupus nephritis as African-Americans and both were higher than Caucasians. East Asians were not significantly different in frequency of end stage kidney disease compared with African-Americans. East Asians were more likely than Caucasians to have anti-Sm, low C3 and low C4. East Asians were more likely than African-Americans to have low C3 and low C4.

Conclusion: East Asians living in the United States were more likely to have lupus nephritis than Caucasians. Poor outcomes such as end stage kidney disease occurred at an equal frequency in East Asians as in African-Americans. Lupus nephritis was both more frequent and more severe in East Asians than in African-Americans.
