Purpose: The aim of this study was to examine the psychometric properties of the Turkish versionof the Compliance Questionnaire on Rheumatology (CQR-T) for patients with Behçet’s disease (BD). Method:A sample of 105 Turkish patients with BD participated in this study. The scale was cross-culturally adapted through a process including translation, comparison with versions in other languages, back translation, and pretesting. Construct validity was evaluated by factor analysis, and criterion validity was evaluated using the Morisky Medication Adherence Scale. Results: The CQR-T demonstrated acceptable internal consistency (Cronbach’s α = .832), adequate test–retest reliability (intraclass correlation coefficient = .630), and correlations with Morisky Medication Adherence Scale scores (r = −.389, p< .001), indicating convergent validity. Conclusion:The CQR-T was found to be a valid and reliable instrument for evaluating the compliance of Turkish BD patients with prescribed medications. Implications for Practice: The CQR-T might be a helpful tool in two ways: for determining the level of compliance of patients with BD and for adjusting their management and follow-up based on the results.

Angiogenesis is controlled by a variety of angiogenesis stimulators and inhibitors. The increased power Doppler (PD) signals determined by ultrasonography is an indirect marker of synovial vascularity in arthritis. We aimed to investigate relationship between ultrasonographic findings and synovial angiogenesis modulators. Thirteen Behcet's disease (BD), 15 spondyloarthropathy, 21 rheumatoid arthritis (RA), and 15 osteoarthritis (OA) patients with knee arthritis were included. Cumulative effusion, synovial hypertrophy, and PD signal scores were calculated in arthritic joints. In synovial fluid samples, angiogenesis inhibitors (angiostatin, thrombospondin-1, and endostatin) and stimulators [bFGF (basic fibroblast growth factor), angiopoietin-1] were studied. The comparisons between groups were made by Kruskal-Wallis test, and correlation analysis was calculated with Pearson and Spearman tests. Effusion scores were significantly higher in inflammatory arthritis than in OA. Synovial hypertrophy scores were higher in RA and spondylarthritis than in OA and BD. PD scores were not different between the groups. Synovial angiostatin and bFGF levels were significantly higher in patients with inflammatory arthritis than in OA. Cumulative effusion scores were positively correlated with angiopoietin-1, angiostatin, and bFGF and negatively correlated with thrombospondin-1 levels. Synovial hypertrophy scores were positively correlated with angiostatin and bFGF levels and negatively correlated with thrombospondin-1. No correlation was found between PD scores and modulators of angiogenesis. In large joints like knee, detecting PD signals alone was not sufficient to assess the angiogenesis. However, cumulative activity scores were positively correlated with angiogenesis stimulators. Therefore, when investigating the angiogenesis, PD technique should be added to gray-scale examinations.

Objective: The aim of the study was to evaluate the influence of dental and periodontal treatments to the course of oral ulcers in patients with Behcet’s disease (BD). Methods: Fifty-eight consecutive BD patients with oral ulcers were studied. Twenty-nine patients were in the intervention group (F/M: 15/14, mean age: 39.6 ± 6.9 years) and 29 (F/M: 15/14, 39.4 ± 10.6 years) were followed with a conventional treatment approach. In addition to oral hygiene education, dental and periodontal treatments were carried out in the intervention group, whereas the control group was only given oral hygiene education. Patients were evaluated in the pre-treatment observation period (1 month), treatment period (1 month) and 6 months after treatment. Results: An increase in the number of new oral ulcers (4.1 ± 3.5) was observed within 2 days during the treatment compared with 3–30 days during treatment month (2.3 ± 1.2) ( P = 0.002). However, 6 months after the treatment, the number of oral ulcers (1.9 ± 1.5) was significantly lower compared with the pre-treatment observation (4.8 ± 3.2) ( P = 0.000) and treatment periods (6.4 ± 2.3) in the intervention group ( P = 0.05), whereas a similar oral ulcer presence was observed in the control group (2.8 ± 2.4, 3.7 ± 2.3 and 4.8 ± 4.3, respectively) ( P > 0.05). Dental and periodontal indices were also better in the intervention group during the 6-month follow-up. Conclusion: Our results suggest that, in BD patients, dental and periodontal therapies could be associated with a flare-up of oral ulcers in the short term, but may decrease their number in longer follow-up. They also lead to a better oral health. [ABSTRACT FROM AUTHOR]

Behçet’s disease (BD) activity is characterised by sustained, over-exuberant immune activation, yet the underlying mechanisms leading to active BD state are poorly defined. Herein, we show that the human cathelicidin derived antimicrobial peptide LL37 associates with and directs plasma extracellular vesicles (EV) to immune cells, thereby leading to enhanced immune activation aggravating BD pathology. Notably, disease activity was correlated with elevated levels of circulating LL37 and EV plasma concentration. Stimulation of healthy PBMC with active BD patient EVs induced heightened IL1β, IFNα, IL6 and IP10 secretion compared to healthy and inactive BD EVs. Remarkably, when mixed with LL37, healthy plasma-EVs triggered a robust immune activation replicating the pathology inducing properties of BD EVs. The findings of this study could be of clinical interest in the management of BD, implicating LL37/EV association as one of the major contributors of BD pathogenesis.

Muscular involvement in Behçet's disease is rare and there are only a few case reports in the literature. The causes of elevated muscle enzymes in a patient with Behcet's disease are many, including myositis, drug-induced myopathy, metabolic myopathy, and the disease itself. We herein have defined an algorithmic approach to a patient with Behcet's disease and elevated muscle enzymes and report a case of coexisting of lipid storage myopathy. [ABSTRACT FROM AUTHOR]
