Management of immune-mediated glomerular diseases in the elderly

Abstract

The management of immune-mediated nephropathies in the elderly presents unique challenges due to age-related physiological changes, comorbidities, and frailty. This review addresses the clinical workup, diagnostic evaluation, and treatment strategies for this rapidly growing patient population. We highlight the inadequacies of current classification systems and the lack of evidence-based guidelines tailored to individuals ≥75 years. The review discusses the specific considerations in diagnosing and treating common conditions such as minimal change disease, focal and segmental glomerulosclerosis, membranous nephropathy, ANCA-associated vasculitis, infection-related and post-infectious glomerulonephritis, and anti-GBM disease. Managing these diseases requires a nuanced approach due to age-related changes in the immune system and the presence of multiple comorbidities. Immunosuppressive therapy, including corticosteroids, rituximab, and cyclophosphamide, remains a cornerstone of treatment, but the choice and dosage of drugs must be carefully balanced to avoid severe side effects. Comorbidity management, regular monitoring of kidney function, and a patient-centered approach are crucial for improving outcomes and quality of life. A multidisciplinary team can provide comprehensive care, addressing all aspects of the patient’s health. Supportive care, the role of kidney biopsy, and the balance between immunosuppressive therapy and the risk of complications are emphasized. Collaborative, individualized care approaches are recommended to improve outcomes and quality of life for elderly patients with immune-mediated kidney diseases. Future research should focus on including older patients in clinical trials to establish robust, age-specific guidelines.
