Filter by:In this ancillary study on the FoxTreg cohort, the study investigators will select variables to input and thus develop two models (Linear Discriminant Analysis and Decision Tree). The aim of this study is to validate the method in terms of repeatability, reproducibility, control of pre-analytical conditions and sample conservation, to complete the screening of IgA glycosylation in individuals of the FoxTreg cohort and to refine the glycopeptide signature to predict renal involvement.
About 20% children with allergic purpura develop nephritis syndrome or nephrotic syndrome, 1% to 7% to kidney failure or end-stage renal disease. Children with serious damage to health, significantly reduced quality of life and caused heavy economic burden to the family . As the pathogenesis of HSPN is complex, it is difficult to formulate an exact individualized treatment plan.
The study aims to explore the therapeutic value and mechanism of Interleukin-2 on children with Henoch-schönlein purpura.
The purpose of this study is to determine the optimum dosage and application method of Glycosides Of Tripterygium Wilfordii Hook(GTW) for Henoch-Schönlein Purpura Nephritis(HSPN) in children, and develop into the normal treatment protocols for Henoch-Schönlein Purpura Nephritis in children.
This study seeks to understand the journey that patients eventually are diagnosed with vasculitis experience in the period prior to their formal diagnosis by a healthcare provider. Data elements of interest include average time from the onset of the first symptoms to the time a diagnosis of vasculitis is confirmed. Other aims include identifying factors associated with the time to diagnosis. These factors will be divided into: a) intrinsic factors, or so-called "patient-related factors", such as the type of vasculitis symptoms, patient demographics, socioeconomic status, patients' beliefs regarding the etiology of their symptoms, and other factors, and b) extrinsic factors, or "professional/health system factors", such as healthcare access, referral patterns, testing patterns, and other factors. Understanding such factors can guide future efforts to shorten delays in diagnosis and thereby improve outcomes. All analyses will be done for the population of patients with vasculitis as a whole and by individual types of vasculitis.
Henoch-Schönlein purpura (HSP) is the most common vasculitis in children, with an incidence of approximately 10:100 000 children and a slight male predominance (male-to-female ratio of 1.5:1). Henoch-Schönlein purpura nephritis (HSPN) is the principal cause of morbidity for HSP and 1%-7% of HSPN patients may progress to renal failure or end-stage renal disease. Immunosuppressive therapy has become the standard treatment in children with HSPN, however the use of these drugs are still mainly in an off-label manner in clinical practice. Tacrolimus, a calcineurin inhibitor, has been recently suggested in the treatment of HSPN in children. However, the evidence-based clinical data are still limited. Given the potential benefits and unmet need in clinical practice, the purposes of this pilot study were to assess effectiveness and safety of tacrolimus in HSPN children and evaluate the potential impact of CYP3A5.
Henoch-Schonlein purpura nephritis(HSPN) is one of the most common secondary glomerulonephritis in children. A large, prospective, multicenter cohort study is being conducted in three institutions. Eligible Henoch-Schönlein purpura nephritis children will be classified as the experimental group (n=300) and the control group (n=300) based on the interventions they receive. Patients taking Chinese herbal formula will be in the experimental group, and those taking Western medicine will be in the control group. The entire study will last 60 weeks, including a 12-week observation period and a followup at 12 months.
Henoch-Schönlein (HS) purpura is a common cause of renal glomerular injury in children. This condition is responsible for 10-15% of glomerulonephritis in children. The outcome is generally favorable, but up to 5% of patients develop kidney failure. The outcome of patients with kidney biopsy is less favorable with 7-50% of them progressing to chronic renal failure. Prevalence of HS is difficult to determine from literature. Annual incidence is estimated at 6.1 / 100,000 children in the Netherlands and up to 20.4 / 100 000 children in the United Kingdom. The proportion of children with HS who develop renal disease is difficult to determine because the numbers reported in the literature are variable and depend greatly on the type of the reporting center, whether or not specialized in pediatric nephrology. Thus the proportion of renal disease varies from 20% to 100% of children with a HS. The treatment of HS nephropathy (HSN) usually depends on the severity of histological lesions but histological classification is discussed and there is currently no consensus. Randomized studies are scarce and often do not allow to draw clear conclusions. A meta-analysis suggested a positive effect of corticosteroids on renal prognosis of severe forms but in this study the definition of renal disease was very heterogeneous. The only classification of the HSN recognized is from the International Study Group of Kidney Disease in Childhood (ISKDC) which is the following: grade I: minimal glomerula abnormalities, grade II: pure proliferation, grade III: crescents/ segmental lesions <50%,grade IV: crescents/ segmental lesions 50 to 75%, grade V: crescents/ segmental lesions > 75%, grade VI: pseudomesangiocapillary. However, this classification is questioned because it ignores other significant histological lesions such as interstitial fibrosis, tubular lesions, glomerular and interstitial inflammation, the appearance of crescents (segmental or totally encompassing the glomerulus, fibrous or cellular), segmental sclerosis, fibrosis and arteriolar appearance in immunofluorescence. There is currently no consensus on the criteria indicating the initiation of corticosteroid therapy whether oral or intra venous bolus. Some patients with severe clinical and / or histological initial presentation can evolve to remission spontaneously while others who have more moderate initial symptoms will evolve later to kidney failure. The management is therefore heterogeneous. In France, some centers perform a kidney biopsy almost always before starting treatment (or in the days following the start of treatment), while in other centers's treatment decision is based on the biology resulting from the glomerular disease, kidney biopsy being performed possibly in a second time in case of failure of the initial treatment. Principal objective of the study: assessment of the interest for the long term outcome of performing early a kidney biopsy (before the establishment of treatment or within 15 days after the start of treatment) in children with HSN compare to kidney biopsy performed later (depending on the response to initial therapy) or not performed. Secondary objective: assessment of the impact of early kidney biopsy (before the establishment of treatment or within of 15 days after the start of treatment) on the initial treatment HSN : does it modify or not the treatment started right before it (decided on clinical and biological criteria).
