Rare progression to renal failure imposes a burden on children with IgA vasculitis (Henoch-Schönlein purpura, HSP). An abnormal urinalysis on day 7 (7d-UA) may be a surrogate marker for persistent nephritis, but this has not been established. We retrospectively analyzed the risk factors for persistent nephritis in a cohort of 138 children. Of 35 children with abnormal 7d-UA, 24 (69%) had an abnormal urinalysis 6 months after the diagnosis of HSP, which was significantly more than 6 of 103 children (6%) with normal 7d-UA (P < 0...

The aim of the present study was to examine the role and mechanism of interleukin-10 (IL-10)-producing regulatory B cells (B10 cells) in the pathogenesis of Henoch-Schönlein purpura nephritis (HSPN). We examined the percentage of B10 cells, CD19(+)CD24(hi)CD38(hi) B cells, CD19(+)CD24(hi)CD27(+) B cells, Th17 cells, and T regulatory (Treg) cells within the peripheral blood mononuclear cell (PBMC) population in healthy subjects and HSP/HSPN patients. The percentage of B10 cells and CD19(+)CD24(hi)CD38(hi) B cells was reduced in HSPN patients and that of CD19(+)CD24(hi)CD27(+) B cells was decreased only in HSPN patients with hematuria and proteinuria or massive proteinuria...

Henoch-Schonlein purpura is an immunoglobulin A (IgA)-immune complex mediated leukocytoclastic vasculitis that classically manifests with palpable purpura, abdominal pain, arthritis, and hematuria or proteinuria. The condition is much more predominant in children (90% of cases) and commonly follows an upper respiratory infection. We present a case of recurrent Henoch-Schonlein purpura (HSP) complicated by nephritis in an adult female initially categorized as IgA nephropathy (IgAN). We review the pathophysiologic basis of HSP nephritis as the variant of HSP accompanied by renal involvement and its pathogenetic commonality with IgA nephropathy...

Henoch-Schonlein purpura (HSP) is the most common vasculitis in children. Vasculitic processes can involve the lung. Although diffuse alveolar hemorrhage may be seen as one of the manifestation of HSP, it is not a frequent presentation. Here we reported the case of a 10-year-old girl with HSP nephritis who developed pulmonary hemorrhage. The patient was treated successfully with intravenous methylprednisolone. A review of the literature revealed that young age may be a good prognostic sign and that immunosuppressive drugs and supportive management are essential in the treatment...

BACKGROUND: A small percentage of children with Henoch-Schönlein purpura (HSP) develop a chronic form of the disease that often requires prolonged corticosteroid therapy. Disease modifying anti-rheumatic agents (DMARDs) or biologics have been successfully used to treat those refractory cases. Azathioprine is a DMARD that has been reported to be effective in HSP nephritis and in adult cutaneous leukocytoclastic vasculitis, a condition with cutaneous histology similar to HSP. CASE PRESENTATION: A description of 6 cases with relapsing HSP without significant renal involvement, treated with azathioprine are reported...

Koebner's phenomenon occurs rarely in connection with Henoch-Schönlein purpura (HSP). We report two children with HSP who developed Koebner's phenomenon on the second day after the onset of rash. The first was an 11-year-old girl with rheumatic heart disease who presented with abdominal pain for 1 month and subsequently developed rash and nephritis. The second patient was a 7-year-old girl who presented with rash and polyarthritis. To the best of our knowledge, Koebner's phenomenon in childhood HSP has not been reported...

Although kidney disease is much less common in children than in adults, clinicians must remain alert for the renal conditions that occur in this population because prompt diagnosis and management are essential. Acute postinfectious glomerulonephritis occurs as an uncommon sequela of streptococcal and other infections. Management is focused on providing supportive measures, including management of fluid-electrolyte imbalance and hypertension, until the patient recovers. Immunoglobulin (Ig) A nephropathy is a primary glomerulonephritis related to abnormal IgA glycosylation...

Previous studies suggested that interleukin-17 and Th17 cell play an important role in the pathogenesis of childhood Henoch-Schonlein purpura (HSP). The purpose of our study is to elucidate whether the IL17A and IL17F gene polymorphisms are susceptibility genes for the development of HSP in Chinese children. A total of 148 HSP patients and 202 controls were enrolled for analyzing the single nucleotide polymorphisms (SNP) of IL17A (rs2275913, rs8193037 and rs3819025) and IL17F (rs763780 and rs9463772). TaqMan Real-Time polymerase chain reaction method was used in SNP genotyping...

BACKGROUND: Henoch-Schönlein purpura (HSP) or IgA-associated vasculitis is related to immune disturbances. Polymorphisms of the heat shock protein 70-2 gene (HSP70-2) and the tumor necrosis factor-a gene (TNF-α) are known to be associated with immune diseases. The purpose of this study was to investigate the likely association of HSP70-2 (+1267A/G) and TNF-α (+308A/G) gene polymorphisms with HSP in children. METHODS: The polymerase chain reaction restriction fragment length polymorphism method was used to detect the HSP70-2 and TNF-α polymorphisms in 205 cases of children with HSP and 53 controls; and the association of these polymorphisms with HSP and HSP nephritis (HSPN) was analyzed...

AIM: Mutations of the inverted formin 2 gene (INF2), which encodes a member of the formin family, cause autosomal dominant focal segmental glomerulosclerosis (FSGS) and Charcot-Marie-Tooth (CMT) disease-associated FSGS. However, their role in idiopathic FSGS remains unclear. This study investigated INF2 localization in the normal adult kidney and its expression in children with idiopathic nephrotic syndrome. METHODS: We generated a rabbit polyclonal antibody against the conjugated peptide from human INF2 and studied the glomerular expression of INF2 and synaptopodin using normal human adult kidney tissues and tissues from children with glomerular diseases such as minimal change disease (MCD), FSGS, IgA nephropathy (IgAN), non-IgA mesangial proliferative glomerulonephritis (non-IgAN), and Henoch-Schönlein purpura nephritis (HSPN)...
