[Lupus nephritis - does a lot help a lot?]

Lupus nephritis (LN) is a frequent and often serious manifestation of systemic lupus erythematosus, which can lead to the need for renal replacement therapy. Its timely diagnosis and treatment is therefore of crucial importance. The use of targeted immunomodulating therapies and the consistent use of nephroprotective measures in the treatment of LN can now significantly improve the renal prognosis and reduce glucocorticoid-associated toxicity. Recent study data have shown that the combination of different immunomodulating therapies including calcineurin inhibitors or belimumab is superior to therapy with single agents in terms of clinically relevant renal endpoints. This multi-target therapy has now also been included in several recently updated international guidelines. In the future, CAR-T cell therapy could be a promising prospect for patients with refractory lupus nephritis.
