What are the data for the use of sglt2 inhibitors in lupus nephritis?
10 answers
The use of Sodium-glucose co-transporter 2 (SGLT2) inhibitors in lupus nephritis (LN) is an emerging area of interest, primarily due to their established cardio- and nephroprotective effects in chronic kidney disease (CKD) and diabetes. However, the application and efficacy of SGLT2 inhibitors in LN, an autoimmune condition affecting the kidneys, require careful consideration of the available evidence. Initial studies have highlighted the potential nephroprotective benefits of SGLT2 inhibitors in LN, noting their ability to reduce proteinuria, a key marker of kidney damage. Despite these promising findings, major clinical trials on SGLT2 inhibitors have historically excluded LN patients, leaving a gap in comprehensive efficacy and safety data. Experimental studies have shown increased expression of SGLT2 in LN, suggesting a mechanistic basis for the potential benefits of these inhibitors in this condition. A trial assessing the effect of Dapagliflozin in patients with inactive Lupus Nephritis with residual proteinuria is underway, aiming to provide more definitive evidence on the efficacy of SGLT2 inhibitors in reducing proteinuria among LN patients. This is crucial as proteinuria is strongly associated with the progression to end-stage renal disease in LN, highlighting the importance of interventions that can mitigate this risk. Safety profiles of SGLT2 inhibitors in SLE patients, including those with LN, have been generally acceptable, with a phase I/II trial showing a manageable safety profile but calling for further research to explore long-term effects. The renoprotective effects of SGLT2 inhibitors, demonstrated in broader CKD populations, including non-diabetic CKD, suggest a potential benefit in LN, although specific studies in LN are needed to confirm this. Mechanistically, SGLT2 inhibitors have shown anti-inflammatory effects in rodent models, reducing levels of inflammatory markers, which could be beneficial given the inflammatory nature of LN. Real-world experiences with SGLT2 inhibitors in non-diabetic CKD, such as IgA nephropathy, have shown good compliance and no serious adverse events, indicating a potential for safe use in LN. Advocacy for the exploration of SGLT2 inhibitors in LN is based on their strong nephroprotective potential and the need for effective treatments to manage kidney and cardiovascular health in LN patients. In summary, while the data on the use of SGLT2 inhibitors in lupus nephritis is promising, particularly in terms of nephroprotection and reduction of proteinuria, comprehensive clinical trials are needed to fully understand their efficacy, safety, and long-term benefits in this specific patient population.
