The Expression Profile of New Complement Components in Childhood Lupus Nephritis

7. oktober 2021 opdateret af: Aya Khalifa, Assiut University
The aim of this study was to evaluate whether C4d is a better biomarker and examine whether C4d plasma levels correlate with treatment response and C4d kidney deposition in systemic lupus erythematosus (SLE) with lupus nephritis (LN).

systemic lupus wth renal affection
pt diagnosed with lupus nephritis
Kombinationsprodukt: C4d evaluation in lupus nephritis in serum and renal tissue
C4d plasma levels were analyzed by a unique assay specifically detecting C4d arising from complement activation and C4 plasma levels were quantified with competitive ELISA. SLE patients in activitity with and without lupus nephritis In patient with lupus nephritis we will evaluate the C4d after developing remission in the form of reduction of proteinurea less than .5g/g measured as PCR as complete response and less than50% reduction in proteinurea in partial response according to KIDGO guide line Percutaneous renal biopsies were performed in SLE and non-SLE patients under ultrasonographic guidance. 10% formalin-fixed tissue was embedded in paraffin. Four μm-thick sections were stained with hematoxylin and eosin (H&E), periodic acid-Schiff (PAS), periodic acid methenamine silver (PAM), masson-trichrome and polyclonal rabbit anti-human C4d antibody, Renal biopsy specimens of SLE patients were assessed using the most recent modification of the World Health Organization (WHO)
