Henoch-Schönlein purpura (HSP) is an acute smallvessel leucocytoclastic vasculitis. HSP is the most common vasculitis in children, with an incidence of about 10 cases per 100 000 a year. In most series, boys are aff ected more often than girls. Although it can occur at any age, HSP is overwhelmingly a disease of childhood. The mean age of patients is 6 years; 75% of patients are under 8 years o...
BACKGROUND Henoch-Schönlein purpura (HSP) is the most common vasculitis in childhood; nevertheless, its etiology and pathogenesis remain unknown despite the fact that a variety of factors, mainly infectious agents, drugs and vaccines have been suggested as triggers for the disease. The aim of this study was to estimate the association of HSP with drug and vaccine administration in a pediatric p...
OBJECTIVE To describe the extrarenal symptoms and clinical course of Henoch-Schönlein purpura (HSP). DESIGN A prospective national multicentre trial with 6-month follow-up. Patients A total of 223 newly diagnosed paediatric HSP patients. RESULTS Purpura was the initial symptom in 73% of the patients and was preceded by joint or gastrointestinal manifestations in the rest by a mean of 4 days...
Case report A 14-year-old male was admitted with a five months history of recurrent purpuric papules on his buttocks and lower limbs lasting up to four days with a burning sensation. The patient had a 10 year medical history of epileptic absences treated with valproic acid 300 mg daily before the initiation of purpura. Laboratory screening for cutaneous vasculitis was unremarkable including ful...
A child showing signs of Henoch-Schönlein purpura developed a right tibiofibular vascular thrombosis. Antiphospholipid antibody tests were positive for both lupus anticoagulant and anticardiolipin antibodies. This suggests that an antiphospholipid syndrome should be considered in cases of Henoch-Schönlein purpura and antiphospholipid antibodies should be measured to determine whether prophylact...
INTRODUCTION To determine whether the PTPN22 (protein tyrosine phosphatase nonreceptor 22)/CSK (c-src tyrosine kinase) pathway is implicated in the susceptibility and clinical heterogeneity of Henoch-Schönlein purpura (HSP) in the largest series of Caucasian HSP patients ever assessed for genetic studies. METHODS A set of 329 Spanish patients diagnosed with HSP fulfilling the American College...
OBJECTIVE Pathogenesis of Henoch-Schönlein purpura (HSP) is not clearly defined. The present study was conducted to investigate the alterations in erythrocyte deformability and oxidative stress in HSP and to examine the possible relationship between erythrocyte deformability and organ involvement in this disease. METHODS Plasma malondialdehyde (MDA) levels, total antioxidant status (TAS), ery...
OBJECTIVES The aim of this report is to evaluate the plasma exchange as a choice for the management of life-threating gastrointestinal system (GIS) involvement in Henoch-Schönlein purpura (HSP) when refractory to conventional therapies. METHODS We retrospectively reviewed the medical records of HSP patients who had plasma exchange therapy due to massive GIS involvement. We reported age, gende...
Henoch-Schönlein purpura (HSP), a common allergic hemorrhagic disease, occurs frequently in children affecting kidney, joint and skin. While interleukin-8 (IL-8) plays an important role in inflammation, the association between IL-8 gene +781 C/T polymorphism and HSP remains unclear. Interleukin-8, an important chemokine related to the initiation and amplification of acute inflammatory responses...
Henoch-Schönlein purpura (HSP) is a small-vessel vasculitis of autoimmune hypersensitivity, and renin-angiotensin system (RAS) regulates vascular homeostasis and inflammation with activation of cytokine release. Thus, we aimed to investigate the association between HSP and ACE I/D and AGT M235T polymorphisms. Genotyping was determined by allele specific PCR and PCR-RFLP. We obtained a significa...
