Renal Survival in Patients with Lupus Nephritis in Assiut University Hospital: a Single-center Study

Systemic lupus erythematous is a chronic multifactorial autoimmune disease that affects many organs including kidney. Lupus nephritis is a common manifestation characterized by heterogeneous clinical and histopathological finding and often associate with poor progression and despite potent anti-inflammatory and immunosuppressive therapies still end in CKD or ESRD for too many patient. lupus nephritis is an immune complex GN that develop as a frequent complication of SLE. The pathogenesis of lupus nephritis involve a variety of pathogenic mechanisms, intra renal pathomechanisn of SLE related nephritis immune complex formation and classical complement pathway activation. Lupus nephritis doesn't develop in the absence of antinuclear antibodies. Circulating polyclonal autoantibodies bind to intrarenal nucleosomes and other autoantigen, which lead to local complement activation , cell injury and subsequent cytokine and chemokine secretion . The current management of lupus nephritis remain based on steroids, cyclophosphamide, azathioprine ,mycophenolate mefetile which are all unselective immunosuppressive drugs, these drugs have proven to be efficient in reducing lupus nephritis disease activity but the long term outcomes of lupus nephritis have not further improved during the last 30 years . Identification of renal survival is mandatory for certain purposes i.e, evaluation of efficacy of different treatment strategies among our patients and factors associated with the survival data as compared with other specialized centers.
