The aim of this study is to explore if an already established diet with anti-inflammatory effect in paediatric inflammatory bowel disease would have an anti-inflammatory effect in children with JIA. The diet is called specific carbohydrate diet.
Aims of this study is to identify the mechanisms of the dissociation between the inflammatory activity and the joints destruction in patients with rheumatoid arthritis (RA) in remission but presenting a progression of the bone erosions. 160 total patients will be enrolled. Males and females RA patients in clinical remission or not, osteoarthritis patients and patients hospitalized for any other orthopedics pathology (used as controls) will be enrolled. From RA patients with bone erosion, OA patients and controls whole blood will be collected; from RA patients without bone erosion whole blood will be collected. From whole blood mononuclear cells will be isolated and plasma will be harvested. From both RA and OA patients synovial fluid will be collected along with mononuclear cells present in this fluid and from both RA and OA patients candidate for total articular replacement fragments of synovial membrane, cartilage, bone and bone marrow will be collected during surgery as waste material. The nuclear cells isolated from whole blood, synovial fluid and bone marrow will be characterized using a panel of markers. Protein arrays on plasma samples obtained from RA, OA patients and controls will be performed to identify a panel of acute phase proteins, cytokines and chemokines present at systemic levels and to highlight analogies and differences in the systemic protein profile. The synovial fluid will be used to identify the proteins present in the synovial fluid of RA and OA patients. The main identified target will be quantified and used as markers of erosion progression, to develop intra-articular pharmacological therapies and to suggest the therapeutic doses of drugs. The same kind of analysis will be performed even on tissues obtained from surgical patients (RA and OA patients) to establish the pathways involved and the tissue specific targets to be stimulated, i.e. with trophic factors, to promote the tissue homeostasis after switching-off the autoimmune and inflammatory processes.
The high resolution chest scan is the gold standard for the screening of interstitial lung disease, but this remains an onerous examination, and irradiating. Ultrasound could be used to detect these disorders with a very good sensitivity and specificity. This exam offers the advantage of being non radiating, inexpensive, and accessible to the rheumatologist who already uses it in their daily practice. The investigators want to assess the lung ultrasound performance compared with the gold standard. Patients will be included during a regular follow-up consultation with their referent rheumatologist. If there is an indication of first line biotherapy or targeted therapy the doctor will propose to the patient to participate in the study, give him the information leaflet, collect orally non-opposition, and will complete a survey for evaluation of the general health and potential risk factors for interstitial lung.
Several prior studies have shown that dose reduction of Tumor Necrosis Factor (TNF)-inhibitors like adalimumab is possible in substantial number of rheumatic disease patients without an increase in disease activity. Biologic therapy is expensive, and is associated with patient burden as dose dependant risk for serious infections . A dose reduction will decrease the risk of side effects and result in substantial cost savings. Currently, most clinicians use Disease Activity Score in 28 joints (DAS28) and the Clinical Disease Activity Index (CDAI) to monitor dose tapering strategies. Although this approach is cost-effective, it might be improved by information on the extent of drug levels, as several studies have shown that adalimumab drug levels are associated with clinical outcome. Therefore, a study comparing dose reduction strategy using drug concentration with dose reduction strategy using disease activity is timely
Patients with chronic inflammatory diseases (CID) followed in gastroenterology, dermatology and rheumatology have physiopathological, epidemiological and therapeutic focal points. The pathologies concerned are inflammatory bowel diseases (IBD - Crohn's disease [MC] and ulcerative colitis [RCH]), chronic inflammatory skin diseases (psoriasis or Verneuil's disease) and chronic inflammatory rheumatic diseases (rheumatoid arthritis [RA] and spondyloarthritis [SpA] including psoriatic arthritis [PsA]). Presenting one of these diseases is associated with a higher risk of having a second inflammatory pathology, whether the latter is ophthalmological, dermatological, rheumatological or gastroenterological. An association of extra-articular manifestations is observed in 10 to 30% of patients with SpA, and an association of extra-intestinal manifestations is observed in approximately 30% of patients with IBD. No common database for chronic systemic inflammatory diseases currently exists in France.
This will be a prospective, observational, single-arm, registry study based on data received from Chinese Registry of rheumatoid arthritis (CREDIT) database to register 200 Chinese RA patients treated with golimumab in one year. Patient characteristic, clinical effectiveness and drug adherence of golimumab will be evaluated.
The purpose of this study is to learn whether changing diet impacts psoriatic arthritis (PsA).
The primary objective of this study is to evaluate the safety, tolerability and pharmacokinetic (PK) profiles of multiple abdominal subcutaneous injection of GB224 in combination with oral methotrexate in Chinese patients with moderate and severe active rheumatoid arthritis in two dose groups; the secondary objectives are to preliminarily evaluate the clinical efficacy such as ACR20 at week 32, ACR20, ACR50 and ACR70 at weeks 12 and 24, ACR50 and ACR70 at week 32, and DAS28 at weeks 12, 24 and 32 of multiple abdominal subcutaneous injection of GB224 in combination with oral methotrexate in Chinese patients with moderate and severe active rheumatoid arthritis in two dose groups as well as to preliminarily understand the immunogenicity and changes in pharmacodynamic variable (IL-6) of multiple abdominal subcutaneous injection of GB224 in combination with oral methotrexate in Chinese patients with moderate and severe active rheumatoid arthritis in two dose groups.
This study compares the similarity of the proportion of subjects who achieved ACR20 at week 30 in the two groups.
