BACKGROUND The magnitude of the therapeutic effects of intra-articular injection of hyaluronic acid on osteoarthritis of the knee is still in question. The aim of this meta-analysis was to elucidate the therapeutic efficacy and safety of intra-articular injection of hyaluronic acid for osteoarthritis of the knee. METHODS We conducted a meta-analysis of(More)
CD4(+) CD25(+) regulatory T cells (Tregs) are critical in maintaining self-tolerance and preventing organ-specific autoimmunity. Their role in paediatric systemic lupus erythematosus (SLE), an autoimmune disease characterized by inappropriate regulation of hyperactivated B and T cells, has not been clearly defined. Using flow cytometry to determine cell(More)
BACKGROUND Henoch-Schönlein purpura (HSP) primarily affects children, but age at onset is thought to be important in determining disease severity and outcome. This study compared the clinical and laboratory data from children and adults with HSP. METHODS This retrospective 5-year study enrolled 65 children and 22 adult HSP patients attending a medical(More)
Henoch–Schönlein purpura (HSP) is an IgA-mediated systemic small vessel vasculitis of childhood. It is characterized by the symptoms including nonthrombocytopenic purpura, abdominal pain, hematuria/proteinuria, and arthargia/arthritis. We conducted a retrospective study of 261 patients diagnosed with HSP from December 1991 to December 2001. Of the 261(More)
Macrophage activation syndrome (MAS) belongs to secondary hemophagocytic lymphohistiocytosis (HLH) syndrome. It is usually associated with rheumatic diseases. We retrospectively reviewed our hospital’s medical records of 102 HLH/MAS patients from the past 20 years. Demographics, clinical data, treatment, and outcomes were analyzed. Among 102 patients, eight(More)
Loosening of total hip arthroplasty (THA) caused by periprosthetic osteolysis induced by ultra-high molecular weight polyethylene (UHMWPE) particles is a major clinical problem. We investigated whether there are differences between loosened THA patients and primary THA patients in (1) receptor activator of nuclear factor-kappaB ligand (RANKL) expression on(More)
IgA nephropathy (IgAN) is the most common glomerulonephritis in the world. The hallmark of IgAN is underglycosylation in the hinge region of IgA1. Increasing evidence supports the underglycosylated IgA-containing immune-complex including IgG antibodies against the glycans of the hinge region of IgA1 are key factors for mesangial deposition and then trigger(More)
Many cytokines, including transforming growth factor-β (TGF-β) and tumor necrosis factor-α (TNF-α), are involved in the inflammatory process of Henoch-Schönlein purpura (HSP). The objective of this study was to investigate whether TGF-β C-509T and TNF-α G-308A polymorphisms are associated with childhood HSP. The loci of interest were amplified from genomic(More)
Kikuchi-Fujimoto disease (KFD) is a rare cause of cervical lymphadenitis which mostly affects Asian women but is sometimes observed in the pediatric population. This study analyzed the clinical manifestations and disease course in children with KFD. Retrospective chart review and telephone interview were used to collect data for 13 children (8 boys and 5(More)
Henoch-Schönlein purpura is one of the most common types of systemic vasculitis in children. Although recurrence is frequent, most cases are benign and self-limited. Standard treatment consists of supportive care and nonsteroid antiinflammatory drugs and/or steroid. Here we report 2 cases of Henoch-Schönlein purpura, both of which had a prolonged and(More)
