Assessing disease phenotypes in Behçet's syndrome: insights from a multiple correspondence analysis.

Introduction: Behçet's syndrome (BS) is a rare systemic vasculitis. Clinical manifestations in BS are frequently clustered rather than discrete, and the concept that distinct clinical phenotypes may exist in BS has recently emerged. The aim of the present work was to identify and analyze the disease phenotypes in a monocentric historical cohort of patients with BS.

Sleep and circadian parameters in Behçet's syndrome: a comparative analysis using actigraphy and questionnaires.

Objective: Sleep disturbances are highly prevalent in Behçet Syndrome (BS) patients. Within this population, sleep disturbances are frequently associated with active disease and comorbid fibromyalgia. However, possible sleep impairments in BS patients without these conditions remain poorly explored, along with BS patients' obstructive sleep apnea (OSAS) risk and circadian rhythm preferences.

European Reference Network (ERN) ReCONNET methodology for the cross-cultural adaptation of instruments for research and care in the context of rare connective tissue diseases (CROSSADAPT).

The traditional process of intercultural adaptation, while suitable for one or a few target languages, is not optimal for developing instruments for rare connective tissue diseases (CTDs) in multiple languages simultaneously. The European Reference Network ReCONNET presents the protocol for a novel methodology for cross-cultural adaptation of instruments for research and care in the context of rare CTDs (ReCONNET-CROSSADAPT). It is initiated by the identification of 'key-terms' that are crucial for maintaining the original meaning of the source document.

The role of tobacco smoking in anti-neutrophil cytoplasmic antibody-associated vasculitis: a systematic review.

Objectives: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of systemic pauci-immune necrotising vasculitides involving small vessels, characterised by the presence of specific ANCA autoantibodies directed to leukocyte proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA) and subdivided into three clinical entities: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). The aetiology of AAV is unknown and many genetic, epigenetic and environmental factors have been reported to be involved in pathogenesis. Smoking is widely recognised as a risk factor for the development of many autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus.

The impact of environmental factors on aetiopathogenesis and clinical manifestations of Behçet's syndrome.

Behçet's syndrome (BS) is a rare multisystem vasculitis involving blood vessels of any size. BS aetiology is still unclear to date, and the heterogeneity of clinical expression among ethnics and genders make early diagnosis challenging. However, so far, considerable efforts have been made toward the understanding of BS, leading researchers to agree that the coexistence of some environmental triggers and a genetical susceptibility both underlie BS aetiopathogenesis.
