Filter by:In healthy subjects, from 50 to 80 % of the serum ferritin is glycosylated [1, 2] . A decrease in the percentage of ferritin glycosylation can be observed in inflammatory diseases, malignancies, infections, or liver disease but is rarely less than 20% [3 , 4] . Percentage of glycosylated ferritin below 20% have been described in patients with adult Still's disease and haemophagocytosis lymphohistiocytic syndromes (HLH). The glycosylated ferritin has been included in the diagnostic criteria for Still's disease in adults. A cut-off of less than 20 % has a sensitivity and specificity of 72 and 69 % respectively , and 35 and 94 % when combined with a total ferritin level greater than 5 times normal value. This parameter was also suggested to be a more specific marker to confirm a diagnosis of HLH than a high ferritin level ( > 500μg / L). However, several limitations of this parameter were highlighted, some conditions making its interpretation difficult : particularly in cases of major hepatic cytolysis and severe sepsis (miliary tuberculosis, lymphoma and disease Adult Still). It is not always possible to distinguish severe sepsis, HLH syndrome and Still's disease. A fine analysis of various glycoforms components of ferritin could be used to distinguish different subgroups of patients. Few data are available on the mechanism of secretion and glycosylation of ferritin, but the investigators assume that the glycosylation patterns of ferritin may vary between different disease states and reflect distinct underlying pathophysiological mechanisms.
Approximately 600 pediatric patients prescribed Humira Injection in usual practice according to the approved Korean product label will be registered into this observational study. Baseline data will be obtained at enrollment including demographics, underlying diseases and complications especially in regard to purified protein derivative (PPD) skin test, chest X-ray. At routine visits for Humira Injection administration which will occur according to usual medical practice, concomitant medication information and adverse events information will be collected for up to 70 days after the last administration of Humira.
One of the main potential causes of these failures of BP therapy response is the development of Anti-drug Anti-body (ADAb) in some patients. ADAb may decrease the efficacy of BPs by neutralizing them or modifying their clearance and they may be associated with BP-specific hypersensitivity reactions. The prediction, prevention and cure of anti-drug (AD) immunization are thus major goals in BP development. This prospective study (ABI-RA) will assess the occurrence of ADAb using standardized and validated assay(s) and also cellular, genetic and molecular parameters in RA/JIA patients treated with adalimumab, etanercept, infliximab and rituximab or tocilizumab, to address the mechanism of immunogenicity. Patient-related factors that might predispose an individual to an immune response will be taken into account: underlying disease, genetic background, immune status, including immunomodulating therapy and dosing schedule.
Juvenile idiopathic arthritis (JIA) is considered to be a multifactorial disease caused by a combination of environmental factors and predisposing genetic factors. Twins studies found a strong heritability (strong genetic factors) but genetic studies such association studies of large cohorts of patient (GWAS or Genome Wide Association Study) have elucidated less than 20 % of the genetic basis of JIA. The vision of the genetics of multifactorial diseases has recently changed revealing a large clinical and genetic heterogeneity of these diseases. Indeed, the advent of next-generation sequencing identified non-multifactorial genetic hereditary disease related to mutations in genes having strong effect on the onset of the disease without real impact of environmental factors among the so called "multifactorial diseases" (Parkinson's, diabetes, osteoarthritis, Alzheimer's, hypertension ...)The investigators propose to study 30 families with several forms of JIA by next-generation sequencing. Identifying the genetic basis of JIA in these families will help to better understand the physiopathology of this disease and may help to the identification of novel therapeutic targets for other patients with JIA.
This study is planned to evaluate the human factor (HF)/usability of pediatric or adolescent JIA patients and the caregivers of Juvenile Idiopathic Arthritis (JIA) patients with the Methotrexate Prefilled Pen (including a label comprehension assessment and a device robustness evaluation).
The purpose of this study is to determine the optimal dosage of etanercept in patients treated for idiopathic juvenile arthritis
A randomized double blind clinical trial to assess efficacy of leflunomide in treatment of refractory juvenile idiopathic arthritis. Patients are randomly divided into two groups. In group 1 leflunomide and in group 2 placebos will be added to conventional treatment for three months. therapeutic responses will be evaluated by ACRpedi (American College of Rheumatology Pediatric) scores every 4 weeks.
Modern modular foot-orthoses systems allow an integration of the cost and efficiency benefits afforded by the use of pre-formed semi-rigid FOs components, while simultaneously allowing a high degree of individualisation of prescription. Such systems, while popular, still remain unproven. Recent studies in paediatric rheumatology have made a contribution in developing guidelines with regards to pharmacological intervention in arthritic children. In addition, specific drug therapy protocols have been published to effectively help general practitioners, physiotherapists and ophthalmologists to successfully treat children with JIA patients (BSPAR 2006; Hull 2001; NICE guidelines 2002). A Cochrane systematic review on treatment of pes planus, highlighted that children with JIA were excluded as a group from most of the studies (Ashford et al. 2005). At present little evidence exists for the podiatric management of children affected by this disabling pathology, especially for orthotic management. This research has provided evidence to support the use of readily available off-the-shelf FOs in treating JIA children.
Study Hypothesis: A virtual peer-to-peer support intervention will improve health outcomes and quality of life in adolescents with Juvenile Idiopathic Arthritis
The objective of this study is to evaluate the efficacy of using a reduced-intensity condition (RIC) regimen with umbilical cord blood transplant (UCBT), double cord UCBT, matched unrelated donor (MUD) bone marrow transplant (BMT) or peripheral blood stem cell transplant (PBSCT) in patients with non-malignant disorders that are amenable to treatment with hematopoietic stem cell transplant (HSCT). After transplant, subjects will be followed for late effects and for ongoing graft success.
