Henoch-Schönlein purpura (HSP) is the most common form of systemic small-vessel vasculitis in children, and HSP nephritis (HSPN) is a major complication of HSP and is the primary cause of morbidity and mortality. Previous studies have suggested that inducible nitric oxide synthase (iNOS) may play an important role in the pathogenesis of HSP. In this study, we performed a detailed analysis to investigate the potential association between iNOS polymorphisms and the risk of HSP and the tendency for children with HSP to develop HSPN in a Chinese Han population...

To investigate whether red blood cell distribution width (RDW) is a marker of the risk of Henoch-Schonlein purpura (HSP) nephritis (HSPN), a total of 669 HSP patients and 168 healthy controls were included in this retrospective study. Two hundred fifty-six (38.3%) of the patients had kidney involvement. Compared with the HSP group, RDW was significantly higher in the HSPN group (P < .001). Binary logistic regression identified that HSPN was independently associated with age, RDW, platelet, and total cholesterol (odds ratio = 1...

Heat shock proteins (HSPs) mediate a diverse range of cellular functions, prominently including folding and regulatory processes of cellular repair. A major property of these remarkable proteins, dependent on intracellular or extracellular location, is their capacity for immunoregulation that optimizes immune activity while avoiding hyperactivated inflammation. In this review, recent investigations are described, which examine roles of HSPs in protection of kidney tissue from various traumatic influences and demonstrate their potential for clinical management of nephritic disease...

Henoch-Schönlein purpura (HSP) is typically seen as a self-limiting disease in children, but can present more severely in adults, especially when there is renal involvement. Management of HSP in adults also remains a controversial topic with very few studies evaluating available therapies. In this case, HSP presenting as a combination of severe gastrointestinal involvement and a rapid decline in renal function in an adult patient directed our therapy. The patient was a 48-year-old Caucasian male with no known past medical history, who presented with a combination of purpuric rash over the lower extremities, severe abdominal pain with upper gastrointestinal bleeding and a rapidly increasing serum creatinine, with hematuria...

Henoch Schönlein purpura (HSP), also known as IgA vasculitis (IgAV), is a systemic small-vessel vasculitis that predominantly affects adolescents and is rare in adults. In many cases, the onset of HSP has been causally linked to an infectious disease. We encountered a case of HSP with severe renal involvement diagnosed by renal biopsy following bacillus Calmette-Guerin (BCG) therapy for bladder cancer. This is of clinical relevance, as intravesical BCG administration is becoming an established therapy for superficial bladder cancer and is supposed to be safe...

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...
