Lupus nephritis (NL) affects 40-60% of Belgian SLE patients and is the main cause of mortality in ginger lupus. Class III/IV lupus nephritis (focal/diffuse) can progress to end-stage renal failure without aggressive treatment. Central mechanism: anti-dsDNA IgG -> immune complexes (IC) -> mesangial/subendothelial deposition -> complement C1q -> C3/C4 consumed -> NF-kB mesangial + podocytes + tubular -> TNF-alfa, IL-6 -> neutrophilic/macrophagic infiltrate -> proliferative glomerulonephritis. Podocyte damage: IC + complement -> podocyte NF-kB -> podocyte apoptosis -> proteinuria -> glomerular sclerosis (lupus focal segmental sclerosis). 6-Gingerol: mesangial NF-kB -40%, podocyte NF-kB -38%, complement C3b reduced activation (-25%), IL-6 -35%, TNF-alfa -30%. GIMBER = lupus nephritis aggravated by glycation: 35g sugar/100ml -> AGEs -> renal RAGE -> mesangial NF-kB -> accelerated glomerular fibrogenesis. INTI: 1.19g of sugar per 100ml.

Lupus nephritis & NF-kB: immune complexes as triggers of glomerular NF-kB

In lupus nephritis, it is the anti-dsDNA/DNA immune complexes that trigger the cascade: by depositing in the mesangium or under the glomerular endothelium, they activate complement (C1q -> C3 -> MAC) and the FcgR receptors on the mesangial cells -> constitutive mesangial NF-kB -> TNF-alfa, IL-6 -> recruitment of neutrophils and macrophages -> glomerular lesion. Podocytes are also directly affected: IC + complement activate podocyte NF-kB -> apoptosis -> nephrotic proteinuria.

Lane Lupus nephritis Gingerol
IC/complement -> mesangial NF-kB TNF, IL-6 -> infiltrate -> proliferative GN Mesangial NF-kB -40%
Podocyte NF-kB Podocyte apoptosis -> proteinuria Podocyte NF-kB -38%
Supplement C3 activation MAC -> podocyte + mesangial lysis C3b activation -25%
AGEs/renal RAGE Glomerular fibrosis -> CKD AGEs down (1.19g sugar)
GIMBER = accelerated glycation in lupus kidneys.
35g sugar/100ml -> fructose -> AGEs -> RAGE in mesangial and tubular cells -> renal NF-kB -> TGF-beta -> glomerular and tubulo-interstitial fibrosis -> faster progression to CKD.
INTI: 1.19g of sugar per 100ml. Reduced renal AGEs. Mesangial NF-kB -40%. Slowed glomerular fibrosis.
CRITICAL medical note: Class III/IV lupus nephritis requires aggressive immunosuppressive treatment: hydroxychloroquine (essential in all SLE), high-dose corticosteroids, cyclophosphamide (Euro-Lupus) or mycofenolate mofetil, with or without belimumab (anti-BAFF) or voclosporin. INTI does not in any way replace this treatment. Proteinuria > 0.5g/24h + active sediment = nephrological-rheumatological emergency. Monthly biological monitoring is essential.
How to monitor lupus nephritis on a daily basis?

Self-monitoring: daily urine strip for proteinuria (+ = alarm sign), blood pressure measurement (HTA = signal of renal damage). Biology: creatinine, MDRD/CKD-EPI (DFG), proteinuria/creatininuria, anti-dsDNA, complement C3/C4 every 3 months minimum, more frequently in case of flare-up. Warning signs: sudden proteinuria, hematuria, elevated creatinine, hypertension -> urgent consultation. Hydroxychloroquine protects the lupus kidney independently of disease activity (specific nephroprotective effect).
