Filter by:Behçet's syndrome (BS) is an idiopathic, chronic, multi-systemic inflammatory disorder characterized by ocular disease, skin lesions, vascular, neurological and gastrointestinal involvement. A recent study showed a peculiar dysbiosis of gut microbiota (GM) in BS patients, with specific changes in the profiles of short-chain fatty acids, especially butyrate. Over the last few years, a growing interest on the role of GM in metabolic disturbances has been manifested. Diet is one of the major factors driving the GM composition and functionality. In this context, the influence of diets generally recognized healthy on GM has been explored, but consistent data on autoimmune and inflammatory diseases are not available. The aim of this intervention study is to investigate whether a lacto-ovo-vegetarian diet enriched in substrates with potential for butyrate production or a Mediterranean diet supplemented with oral butyrate could be beneficial for GM and metabolic risk profile in BS.
Although Behçet's Disease (BD) has no FDA-approved therapies, numerous clinical reports suggest that oral ulcers of BD may resolve when treated with systemic ingested pentoxifylline (PTX). The investigators here propose to investigate the therapeutic potential of PTX dissolved in muco-adherent formulation and directly applied to the oral lesions. This 60 patient proof of concept trial is designed to meet regulatory requirements for safety concerns while at the same time exploring the potential efficacy and clinical utility of this product. The investigators hypothesize that application of topical PTX will accelerate the healing of these lesions in a clinically meaningful way, and further hypothesize that topical PTX can become a valuable adjunct to any other systemic therapy for BD.
The aim of our study was to assess serum endocan levels in patients with Behcet disease and to correlate it with various disease clinical and laboratory parameters of disease activity as well as carotid intima media thickness.
In the literature, the relationship between fibromyalgia and disease activity has been assessed in a few studies without discrimination between women and men.In this study, it was aimed to evaluate the relationship between fibromyalgia and disease activity in women with Behçet's disease.
There are few studies in the literature regarding increased frequency of neuropathic pain and sleep disturbance and decreased quality of life in Behçet's disease. Frequency of central sensitization was not investigated in patients with Behçet's disease before. In this study, it is aimed to investigate the frequency of central sensitization, neuropathic pain, sleep disorder and quality of life and their relation to each other in Behcet's disease.
In various studies, the incidence of fibromyalgia in Behçet's patients is widely distributed. It was aimed to investigate the frequency and severity of fibromyalgia in Behcet disease in province Bursa.
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.
Behçet's disease (BD) is a systemic vasculitis of arterial and venous vessels of any size, involving young patients (from 15 to 45 years). BD significantly increases morbidity and mortality. Therapeutic management of BD depends on the clinical presentation and organ involved. Although colchicine, nonsteroidal antiinflammatory agents and topical treatments are often sufficient for mucocutaneous and joint involvement, more aggressive approach with immunosuppressive agents is warranted for severe manifestations. Early recognition and vigorous use of immunosuppressives with high dose steroids have changed the prognosis of patients with severe BD. BD is a severe systemic vasculitis leading to blindness in up to 20% at 4 years and a 5-year mortality rate of 15% in patients with major vessel or neurological involvement. Cyclophosphamide has been used for life-threatening BD for 40 years. However, the outcome of severe complications of BD is poor. The European League Against Rheumatism (EULAR) recommendation for the management of BD advocated cyclophosphamide plus glucocorticoids for life-threatening manifestations (i.e neurological and/or major vessel involvement). TNFa antagonists have been used with success in severe and/or resistant cases. In addition, the incidence of blindness in BD has been dramatically reduced in the recent years with the use of anti-TNF. However, there is no firm evidence or randomized controlled trials directly addressing the best induction immunosuppressive therapy in severe BD manifestations. The investigators therefore aimed to assess the best induction therapy in severe and difficult to treat BD patients. The investigators hypothesize that up to 70% of the patients with life-threatening manifestations of BD receiving these compounds [anti-TNFa or cyclophosphamide] will achieve a complete remission of BD at 6 months and with less than 0.1 mg/kg/day of prednisone. ITAC, is the first randomized prospective, head to head study, comparing infliximab, to cyclophosphamide in severe manifestations of BD. There is no firm evidence or randomized controlled trials directly addressing the best induction immunosuppressive therapy in severe BD. Cyclophosphamide failed to demonstrate sustainable remission over 70 % of life threatening BD cases. There is little published information on use of immunosuppressants other than cyclophosphamide for severe BD. TNFa antagonists have been used with success in severe and/or resistant cases. TNFa expression correlates with BD activity and other immunological data provide a strong rationale for targeting BD with biologics. Despite a strong rationale, these compounds are not yet approved in BD, which guarantees the innovative nature of this study that aims selecting or dropping any arm when evidence of efficacy already exists.
A dietary intervention trial will be performed on patients affected by Behçet's syndrome. Three different diets will be compared, analyzing their effects on the gut microbiota composition, on endogenous butyrate production and on the general symptoms in Behçet's patients.
Behcet's disease is an important cause of retinal vasculitis and vision loss in Egypt. Fluorescein angiography is the standard method of diagnosis of retinal vasculitis. OCT angiography (OCT-A) is a recently developed method that can be used in the evaluation of retinal circulation. In this study, we will test the utility of OCT-A in diagnosis and follow up of retinal vascular changes in cases diagnosed with Behcet's disease that visit the outpatient uveitis clinic of Assiut University hospital, a major tertiary center in southern Egypt, over a one year duration. Also, correlation of OCT-A changes with visual acuity and hence prognosis will be described.
