Background Lupus nephritis (LN) is a very severe manifestation of lupus. There is no consensus on which treatment goals should be achieved to protect kidney function in children with LN. Methods We retrospectively analyzed trends of commonly used laboratory biomarkers of 428 patients (<= 18 years old) with biopsy-proven LN class >= III. We compared data of patients who developed stable kidney remission from 6 to 24 months with those who did not. Results Twenty-five percent of patients maintained kidney stable remission while 75% did not. More patients with stable kidney remission showed normal hemoglobin and erythrocyte sedimentation rate from 6 to 24 months compared to the group without stable kidney remission. eGFR >= 90 ml/min/1.73m(2) at onset predicted the development of stable kidney remission (93.8%) compared to 64.7% in those without stable remission (P < 0.00001). At diagnosis, 5.9% and 20.2% of the patients showed no proteinuria in the group with and without stable kidney remission, respectively (P = 0.0001). dsDNA antibodies decreased from onset of treatment mainly during the first 3 months in all groups, but more than 50% of all patients in both groups never normalized after 6 months. Complement C3 and C4 increased mainly in the first 3 months in all patients without any significant difference. Conclusions Normal eGFR and the absence of proteinuria at onset were predictors of stable kidney remission. Significantly more children showed normal levels of Hb and erythrocyte sedimentation rate (ESR) from 6 to 24 months in the group with stable kidney remission.
