Summary

Lupus nephritis (LN) develops in 30-60% of systemic lupus erythematosus (SLE) patients and remains a leading cause of morbidity, with 10-30% progressing to end-stage renal disease within 15 years. The International Society of Nephrology/Renal Pathology Society (ISN/RPS) classifies LN histologically, with proliferative forms (Classes III/IV) carrying the poorest prognosis.

Conditions

Interventions

OTHER

renal biopsy

Renal biopsy specimens will be evaluated by light microscopy and will be pathologically classified according to the 2003 International Society of Nephrology/ Renal Pathology Society classification (ISN/RPS Classification) as minimal mesangial (class I), mesangial proliferative LN (class II), focal LN (class III), diffuse LN (class IV), membranous LN (class V) and advanced sclerosis (class VI)

DIAGNOSTIC_TEST

serum anti-alpha-actinin antibodies

Serum sample should be collected into a serum separator tube. After clotting for 2 hours at room temperature or overnight at 4°C, and then centrifuging at 1000 × g for 20 minutes. Assay freshly prepared serum immediately or store samples in aliquot at -20°C or -80°C for later use. Avoid repeated freeze-thaw cycles.

DIAGNOSTIC_TEST

CBC, serum creatinine and urea, estimated GFR, ESR, CRP, urine analysis, ANA, anti dsDNA, C3 & C4, serum albumin, 24-hrs urinary protein, and U. ACR

Laboratory tests including, complete blood count (CBC, serum creatinine and urea and estimated GFR according to CKD-EPI and KDIGO;2024, urine analysis, C-reactive protein (CRP), Erythrocyte Sedimination Rate (ESR), anti-nuclear antibodies (ANA), serum albumin, serum complement (C3 and C4) ,anti-double stranded deoxyribonucleic acid (anti-dsDNA), 24-hrs urinary protein and urinary albumin:creatinine ratio (U. ACR).
