Henoch-Schönlein purpura (HSP) is a commonest systemic vasculitis in childhood. The long-term prognosis of HSP is determined by the degree of renal involvement. The aim of this study is to search novel clinically applicable biomarkers to evaluate renal involvement in HSP patients. 20 bio-indexes in urine samples were simultaneously screened by antibody array assay. We indicated that urinary lev...

Henoch-Schönlein purpura (HSP) is a common systemic small vessel vasculitis in children with disorder autoimmune responses. T follicular helper (TFH) cells play crucial roles in regulating immune responses. The aim of our study was to investigate the probable role of TFH cells in the pathogenesis of children with HSP. In this study, the frequency of circulating CXCR5(+)CD4(+)TFH cells with indu...

Pulmonary-renal syndrome refers to patients with DAH (or pathologic pulmonary purpura on physical examination implies a small-vessel, cutaneous vasculitis ( 10).. The ANCA-associated vasculitides, WG, CSS, and MPA, are grouped. . The syndrome is characterized by a triad of (1) asthma, (2) hypereosinophilia, and . Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatos...

Henoch-Schönlein purpura (HSP) is the most common form of childhood vasculitis. Various viral and bacterial infections, drugs, vaccines, food allergy and even insect bites have been considered as triggering factors in pathogenesis of HSP. Epstein-Barr virus (EBV) infection, which is associated with HSP, have been rarely reported. Herein we present HSP patient possibly caused by EBV infection. A...

Henoch-Schönlein purpura is a small vessel vasculitis with multi-system manifestations that commonly affects children. We describe a case of new onset Henoch-Schönlein purpura in a previously healthy 42-year-old female who required an emergency laparotomy for small bowel perforation.

We compared the production of three chemokines; interferon-gamma-inducible protein-10 (IP-10), monocyte chemoattractant protein-1 (MCP-1) and growth-related onco-gene-alpha(Gro-alpha) that attracts monocytes or neutrophils, or both, in peripheral blood at acute stage of Kawasaki disease (n=29), Henoch-Schönlein purpura (n=15) and acute febrile illnesses (n=12). The production of the chemokines ...

Henoch-Schönlein purpura (HSP) is an immune complex-mediated systemic vasculitis. Its genetic etiology remains unknown. CD18, the subunit of integrin beta2 in leukocytes, has essential roles in the expression and function of ITGB2, mediating immune responses. CD18 has been proved to be associated with some systemic vasculitides, such as microscopic polyangiitis and Churg-Strauss syndrome. We ai...

OBJECTIVE To study the influence of deletion/insertion polymorphism in the 16th intron of the angiotensin converting enzyme (ACE) gene on clinical manifestations of Henoch-Schönlein purpura nephritis. STUDY DESIGN Cross sectional study. ACE gene polymorphism was determined in patients (4-15 years old at onset) with Henoch-Schönlein purpura nephritis (n = 40) and compared with that in patients...

BACKGROUND Matrix metalloproteinase-9 (MMP-9) is an enzyme implicated in the pathogenesis of renal diseases. Renal involvement is the principal cause of morbidity and mortality in children with Henoch-Schönlein purpura (HSP). OBJECTIVES The aim of this study was to evaluate whether serum and urinary MMP-9 levels are associated with renal involvement in HSP. PATIENTS AND METHODS We evaluated...

AIM To evaluate the clinical significance of soluble thrombomodulin and antiendothelial cell antibodies (AECA) in children with Henoch-Schönlein purpura. METHODS Binding of serum AECA to bovine glomerular endothelial cells was evaluated by enzyme linked immunosorbent assay, cytotoxicity against glomerular endothelial cells by spectrophotometric assay, and soluble thrombomodulin concentrations...
