Background. Few data are available about the very long-term outcome of patients with proliferative lupus nephritis. Methods. Ninety-three Italian patients with biopsy-proven proliferative lupus nephritis (15 with class III, 9 with class III + V, 64 with class IV and 5 with class IV + V) followed for a median follow-up of 15 years in a single renal unit were considered for this observational study. Patients were treated with an induction treatment consisting of high doses of corticosteroids plus immunosuppressive agents in the more severe cases. This treatment was repeated in the event of a renal flare. Then corticosteroids and immunosuppressive agents were reduced to the minimal effective dose for maintenance. Results. Renal survival including death was 97% at 10 years and 82% at 20 years. At the last follow-up visit, 59 patients were in complete renal remission, 18 were in partial renal remission, four patients had chronic renal insufficiency, six had entered end-stage renal disease and six patients had died. At multivariate analysis the lack of achievement of complete renal remission and the occurrence of nephritic flares were significantly correlated both with the risk of doubling plasma creatinine and death or dialysis. Those patients who entered complete renal remission had significantly less probability of developing nephritic flares. Conclusion. The long-term prognosis of Caucasian patients with proliferative lupus nephritis may be better than usually thought. Favorable factors for good long-term outcome are the achievement of complete renal remission, the absence of nephritic flares and their complete reversibility after therapy. [ABSTRACT FROM AUTHOR]

We are witnessing a revolution in the treatment of metastatic renal cell carcinoma (mRCC). Indeed, several immune-based combinations (ICI [immune checkpoint inhibitor] + ICI, or ICI + antiangiogenic agents) have been approved as first-line therapy for mRCC after demonstrating superior efficacy over the previous standard. Despite all the improvements made, safety remains a critical issue, adverse events (AEs) being the main reason for drug discontinuations or dose reductions, ultimately resulting in an increased risk of losing efficacy. Thus, a good understanding of the AEs associated with the use of immune-based combinations, their prevention, and management, are key in order to maximize therapeutic effectiveness. Among these AEs, renal ones are relatively frequent, but always difficult to be diagnosed, not to take into account that it is often difficult to determine which drug is to blame for such toxicities. Chronic kidney disease (CKD) is a common finding in patients with RCC, either as a pre-existing condition and/or as a consequence of cancer and its treatment; furthermore, CKD, especially in advanced stages and in patients undergoing dialysis, may influence the pharmacokinetics and pharmacodynamics properties of anticancer agents. Finally, managing cancer therapy in kidney transplanted patients is another challenge. In this review, we discuss the therapy management of immune-based combinations in patients with CKD, on dialysis, or transplanted, as well as their renal toxicities, with a focus on their prevention, detection and practical management, taking into account the crucial role of the consulting nephrologist within the multidisciplinary care of these patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.
