Filter by:Combination therapy, the association of an anti-Tumor Necrosis Factor (TNF) to an immunosuppressant, is recognized as the most effective treatment during Crohn's disease (CD). Several mechanisms have been proposed to explain the superiority of combination therapy over monotherapy, the additive effect of two effective drugs or the prevention of anti-TNF immunogenicity. As the best combination therapy is unknown, both azathioprine (AZA) and methotrexate (MTX) are used. Some retrospective studies suggest a higher effectiveness of AZA. MTX may have an advantage in terms of safety. The investigators hypothesize that AZA is more effective than MTX as combination therapy with adalimumab to improve short-term endoscopic, clinical and pharmacological outcomes in CD patients.
- Psoriasis is a chronic relapsing dermatological disease which often necessitates a long-term therapy and occurs in a significant percent of the population . It affects the skin and sometimes the nails and joints of patients . - Psoriatic patients are frequently categorized into two groups: mild or moderate to severe psoriasis, depending on the clinical severity of the lesions, the percentage of affected body surface area, and patient quality of life . - Topical drug therapy is the cornerstone in the treatment of mild to moderate psoriasis. It offers a direct targeting of affected skin by avoiding systemic adverse events . - Several topical therapies are available for the treatment of psoriasis such as topical steroid , topical vitamin D3 analogues (calcipotriol),tar, anthraline, topical tacrolimus (a non-steroidal calcineurin inhibitor) and tazarotene (a third-generation retinoid) . However, they do not provide an adequate response owing to the inadequate percutaneous absorption and poor patient compliance caused by greasiness and stickiness of some formulations, and some patients even remain untreated . - So that, patient satisfaction with available topical treatments remains modest .
Takayasu arteritis (TAK) is a rare chronic inflammatory arteritis, which lacks an effective well-accepted intervention strategy. Here we tried to classify TAK patients in 3 levels, including mild, moderate, and severe, and prescribe methotrexate and tofacitinib randomly in mild and moderate patients, to observe the relatively better treatment strategy, facilitating better intervention strategy in TAK patients.
Currently there are no guidelines for monitoring hepatic fibrosis associated with long term MTX use. Routine liver biopsies are not being done as a part of surveillance due to potential complications like bleeding and pneumothorax. Non-invasive markers like gammaglamyltransferase (GGTP), Alkaline Phosphatase (AlkPhos), Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are deranged at a late stage and may not be helpful in detecting early fibrosis. The current study will utilize a sensitive, but noninvasive, test to evaluate for hepatic fibrosis. We are attempting to screen for early detection of fibrosis due to MTX before it progresses to irreversible cirrhosis and end-stage liver disease. Based on the results of this pilot study, ultrasound elastography could be used to prospectively study a larger population to establish guidelines for monitoring safety and hepatic complications with MTX. The influence of other co-morbid factors like obesity, alcohol ingestion and smoking is critical to identifying high risk patients who may require closer monitoring. We follow close to 550 patients with IBD. If we presume that at least 20% patients are currently receiving methotrexate, we will be able to recruit enough patients for this pilot study.
Methotrexate (MTX) is the first-line treatment for rheumatoid arthritis (RA). Poor adherence of this treatment decreases the control of the disease and the effectiveness of the associated treatments. The aim would be to study the observance of patients with RA and to be able to propose adequate solutions favoring patient compliance and thus the stability of the pathology. For this purpose, 3 methods of communication have been put in place to encourage adherence: usual care by the rheumatologist, sms sending or pharmaceutical maintenance.
To investigate whether a transient discontinuation of methotrexate MTX for 2 weeks improves the vaccination response to a seasonal influenza.
In this study we aim to determine whether methotrexate influences the metabolism and vascular effects of adenosine in humans in vivo. Adenosine is an endogenous purine-nucleoside with potent anti-inflammatory effects. Also, adenosine receptor stimulation induces vasodilation, ischaemic preconditioning and many other cardiovacular effects. Previous animal studies have provided limited evidence that the anti-inflammatory effects of methotrexate are mediated by adenosine receptor stimulation. In this study, we aim to determine whether also in humans in vivo, methotretate influences endogenous adenosine. Therefore, 10 patients with inflammatory arthritis are treated with methotretxae (15 mg/week orally) for 12 weeks. Before and after treatment, vasodilation to the infusion of adenosine and dipyridamole into the brachial artery is assessed as biomarker for the endogenous adenosine concentration. Also, blood is drawn for the determination of CRP, ESR, Adenosine deaminase activity adn homocysteine.
