[27] highlighted the risk factors for LN relapses, encompassing antiphospholipid syndrome, higher baseline proteinuria, low C3 complement, higher Systemic Lupus Erythematosus Diseases Activity Index (SLEDAI) at inclusion, lower eGFR, lower serum albumin, lower hemoglobin levels, and lower leucocyte, lymphocyte, and eosinophil counts. This evidence concerns the gene C3 and systemic lupus erythematosus.
