Currently, the recommended induction treatment for lupus nephritis class Ⅲ/Ⅳ/V are corticosteroids combined with cyclophosphamide (CYC). Although tacrolimus has demonstrated comparable efficacy to CYC in adult patients with LN, its effectiveness and safety in the treatment of childhood lupus nephritis (cLN) have not been extensively investigated, particularly in comparison to cyclophosphamide (CYC). The objective of this study is to retrospectively assess the effect of calcineurin inhibitors (CNIs) compared to CYC as the initial induction therapy for class Ⅲ/Ⅳ/Ⅴ cLN.MethodscLN of class Ⅲ/Ⅳ/V treated initially with intravenous CYC or CNIs from January 2009 to January 2022 were included.

The CNI group had a significantly higher complete remission (CR) rate (55.2%) compared to the CYC group (17.4%) after 3 months of treatment, and this difference remained at 6 months (62.1% vs 26.1%).

The rate and risk factors of CC in LEP are not well understood. Thus, we conducted a retrospective cohort study on patients diagnosed with LEP.ObjectiveTo quantify the rate of CC and to identify the risk factors associated with its development in LEP.MethodsThis retrospective cohort study analyzed data from 27 LEP patients recruited in outpatient dermatology clinics at University of Texas Southwestern Medical Center and Parkland Health from January 2009 to December 2024. The primary outcome measure was CC development based on clinical diagnosis from a dermatologist, biopsy, or radiographic imaging. Data collected included demographics, smoking history, disease duration, medications, and lesion location. Predictor variables associated with CC development were analyzed either by Mann-Whitney U or Fisher's exact tests.Results10/27 (37%) LEP patients had CC during the evaluation period.
