Henoch-Schönlein Nephritis Manifesting with Purpura 15 years after Diagnosis of IgA Nephropathy

Henoch-Schönlein purpura nephritis.

Henoch-Schönlein purpura (HSP) is a systemic vasculitic disorder first reported by Heberden in 1806. The association of purpura and joint pain was described by Schönlein in 1837, who termed it “peliosis rheumatica.” Henoch added a description of four children with skin lesions associated with colicky abdominal pain, gastrointestinal hemorrhage, and joint pain in 1874, and in 1899 pointed out th...

Chapter 11: Henoch-Schönlein purpura nephritis

11.1: Treatment of HSP nephritis in children 11.1.1: We suggest that children with HSP nephritis and persistent proteinuria, 40.5-1 g/d per 1.73 m, are treated with ACE-I or ARBs. (2D) 11.1.2: We suggest that children with persistent proteinuria, 41 g/d per 1.73 m, after a trial of ACE-I or ARBs, and GFR 450 ml/min per 1.73 m, be treated the same as for IgAN with a 6-month course of corticoster...

Recurrence of IgA nephropathy and Henoch-Schönlein purpura after kidney transplantation: risk factors and graft survival.

BACKGROUND IgA nephropathy (IgA) is one of the most common glomerulonephritis. Renal transplantation is the treatment of choice for patients with ESRD due to any kind of glomerulopathy, including IgA and Henoch-Schönlein purpura nephritis (H-SP), but original disease recurrence is now the third most frequent cause of allograft loss. METHODS Eighty-seven cases of glomerulonephritis as the orig...

Azathioprine treatment in two children with Henoch–Schönlein purpura nephritis

Abnormal IgA glycosylation in Henoch-Schönlein purpura restricted to patients with clinical nephritis.

BACKGROUND Glomerular deposition of IgA1 is a common feature of Henoch-Schönlein purpura, and is indistinguishable from that seen in IgA nephropathy. Serum IgA1 is abnormally O-glycosylated in IgA nephropathy, and this may contribute to mesangial IgA1 deposition and the development of glomerular injury. This altered O-glycosylation of IgA1 can be detected by its increased binding to the lectin ...
