Answer

In a multi-ethnic international cohort of patients enrolled within 15 months (mean, 6 months) after SLE diagnosis and assessed annually, lupus nephritis occurred in 700 of 1827 patients (38.3%). Lupus nephritis was frequently the initial presentation of SLE; it was identified at enrollment in 80.9% of cases. Patients with nephritis were younger, more frequently men and of African, Asian, and Hispanic race/ethnicity. [19]

In a study of a large Spanish registry, lupus nephritis was histologically confirmed in 1092 of 3575 patients with SLE (30.5%). The mean age at lupus nephritis diagnosis was 28.4 years. The risk for lupus nephritis development was significantly higher in men, in younger individuals, and in Hispanics. Patients receiving antimalarials had a significantly lower risk of developing lupus nephritis. [20]
