Does decision tree analysis predict oral ulcer activity-related factors in patients with Behçet's syndrome?

OBJECTIVES: The study aimed to identify the interactions among treatment protocols and oral ulcer activity related factors in patients with Behçet's syndrome (BS) using the Classification and Regression Tree (CART) algorithm. METHODS: In this cross-sectional study, 979 patients with BS were included from16 centres in Turkey, Jordan, Brazil and the United Kingdom. In the CART algorithm, activities of oral ulcer (active vs. inactive), genital ulcer (active vs. inactive), cutaneous involvement (active vs. inactive), musculoskeletal involvement (active vs. inactive), gender (male vs. female), disease severity (mucocutaneous and musculoskeletal involvement vs. major organ involvement), smoking habits (current smoker vs. non-smoker), tooth brushing habits (irregular vs. regular), were input variables. The treatment protocols regarding immunosuppressive (IS) or non-IS medications were the target variable used to split from parent nodes to purer child nodes in the study. RESULTS: In mucocutaneous and musculoskeletal involvement (n=538), the ratio of IS use was higher in patients with irregular toothbrushing (ITB) habits (27.1%) than in patients with regular toothbrushing (RTB) habits (14.2%) in oral ulcer activity. In major organ involvement (n=441), male patients with ITB habits were more likely treated with IS medications compared to those with RTB habits (91.6% vs. 77.6%, respectively). CONCLUSIONS: Male BS patients on IS who have major organ involvement and oral ulcer activity with mucocutaneous and musculoskeletal involvement have irregular toothbrushing habits. Improved oral hygiene practices should be considered to be an integral part for implementing patient empowerment strategies for BS.

Assessment of the effects of loneliness, perceived social support, and depression on medication adherence in patients with ankylosing spondylitis.

PURPOSE: This study aims to investigate the effects of loneliness, perceived social support, and depression on medication adherence of patients with ankylosing spondylitis (AS). DESIGN AND METHODS: This cross-sectional study was conducted with 119 AS patients. Data were collected using the Morisky-Green-Levine Medication Adherence Scale, the UCLA Loneliness Scale (ULS), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Beck Depression Inventory (BDI). FINDINGS: Nonadherent patients were younger (P = .033), scored higher on the ULS (P = .015), and BDI (P = .024) scales, and lower on the MSPSS scale (P = .039) and on family support (P = .002). PRACTICAL IMPLICATIONS: The biopsychosocial aspects of patients with AS should be managed holistically to improve their medication adherence.

The assessment of tocilizumab therapy on recurrent attacks of patients with familial Mediterranean fever: A retrospective study of 15 patients.

AIM: Interleukin-6 receptor antagonist, tocilizumab (TCZ), is known to be effective in the treatment of amyloidosis in patients with familial Mediterranean fever (FMF). But there are limited data about the effect of TCZ on frequency of attacks. In the current study, we aimed to find out whether TCZ therapy could decrease the frequency of recurrent attacks of FMF or not. MATERIALS AND METHODS: The recorded files of 15 patients who had received intravenous TCZ for the improvement of amyloidosis associated with FMF, were evaluated retrospectively. Data of demographic and clinical characteristics of patients were archived from those files. RESULTS: Three female and 12 male patients received TCZ due to amyloidosis were included to the study. The mean age was 42.07 ± 14.37 years. All of the patients were in full compliance with colchicine treatment. According to international severity scoring system for FMF, all of the patients had severe disease. The frequency of attacks recorded was evaluated during TCZ treatment, and it was reported that one patient had no response, six patients had decreased attack frequency and eight patients had no attacks. DISCUSSION: Tocilizumab is found to be efficient on improvement of amyloidosis and decreasing the frequency of recurrent attacks in patients with FMF. Besides, TCZ is well tolerated among the patients. Further and prospective studies with larger sample are needed to support these results.

Predictive factors for work-day loss in Behçet's syndrome: A multi-center study.

OBJECTIVE: The aim of this multi-center study was to assess predictive factors for work-day loss as an indirect cost element in Behçet's syndrome (BS). METHODS: In this cross-sectional, multi-center study, 834 BS patients (F/M: 441/393, age mean: 38.4 ± 10.9 years) were included. Data were collected by a questionnaire regarding treatment protocols, disease duration, smoking pattern, frequency of medical visits during the previous year and self-reported work-day loss during the previous year. RESULTS: Work-day loss was observed in 16.2% of patients (M/F: 103/32). The percentages of being a smoker (81.8%), using immunosuppressive (IS) medications (82%), and having disease duration <5 years (74%) were higher in male patients with work-day loss (P < .05). The majority of males (90.9%) had more than four clinic visits during the previous year. Moreover, the mean work-day loss (30.8 ± 57.7 days) was higher in patients with vascular involvement (56.1 ± 85.9) than those without (26.4 ± 50.6 days) (P = .046). In addition, increased frequency of ocular involvement (25.9%) was also observed in patients with work-day loss compared to others (8.6%) (P = .059). CONCLUSION: Work-day loss was associated with both vascular and ocular involvement. Close associations were observed among male gender, early period of the disease, frequent medical visits, being a smoker and treatment with IS medications in patients with work-day loss.

Oral ulcer activity assessment with the composite index according to different treatment modalities in Behçet's syndrome: a multicentre study.

OBJECTIVES: The aim of this multicentre study was to understand patients' needs and to evaluate the oral ulcer activity with the Composite Index (CI), according to different treatment modalities in Behçet's syndrome (BS). METHODS: BS patients (n=834) from 12 centres participated in this cross-sectional study. Oral ulcer activity (active vs. inactive) and the CI (0: inactive vs. 1-10 points: active) were evaluated during the previous month. The effects of treatment protocols [non-immunosuppressive: non-IS vs. immunosuppressive: (ISs)], severity (mild vs. severe), disease duration (<5 years vs. ≥5 years) and smoking pattern (non-smoker vs. current smoker) were analysed for oral ulcer activity. RESULTS: Oral ulcer activity was observed in 65.1% of the group (n=543). In both genders, the activity was higher in mild disease course with non-IS treatment group compared to severe course with ISs (p<0.05). As a resistant group, patients with mild disease course whose mucocutaneous symptoms were unresponsive to non-IS medications were treated with ISs in a limited period and achieved the highest CI scores in females. Oral ulcer activity and poor CI score were associated with disease duration less than 5 years compared to others in male patients (p<0.05). CONCLUSIONS: Oral ulcer activity pattern is affected by both the combination of disease course, treatment protocols and disease duration. CI scores reflected the oral clinical activity and CI might be a candidate scale to evaluate the efficacy of treatments during the follow-up of oral ulcer activity in BS.

Methodology of a new inflammatory arthritis registry: TReasure

Background/aim: The TReasure registry, created in 2017, is an observational multicenter cohort that includes inflammatory arthritis patients. This article reviews the methodology and objectives of the TReasure registry established to collect data from rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients. Methodology: Fifteen rheumatology centers in Turkey will contribute data to the TReasure database. The actual proprietor of the database is the Hacettepe Rheumatology Association (HRD) and Hacettepe Financial Enterprises. Pharmaceutical companies that operate in Turkey (in alphabetical or er), Abbvie, Amgen, BMS, Celltrion Healthcare, Novartis, Pfizer, Roche, and UCB, support the TReasure registry. TReasure is a web-based database to which users connect through a URL (https://www.trials-network.org/treasure) with their unique identifier and passwords provided for data entry and access. TReasure records demographic and clinical features, comorbidities, radiology and laboratory results, measures of disease activity, and treatment data. Discussion: TReasure will provide us with various types of data, such as a cross-sectional view of the current nationwide status of the patients currently receiving these treatments, and retrospective data as much as allowed by the participating centers' records. Finally, a high-quality prospective dataset will be built over the ensuing years from patients with a new diagnosis of RA or SpA.

A patient-reported outcome measures-based composite index (RAPID3) for the assessment of disease activity in ankylosing spondylitis.

A single questionnaire regarding to disease activity for all rheumatic diseases may present advantages to introduce quantitative measurement into routine care. The aim of this study was to evaluate the correlation of routine assessment of patient index data 3 (RAPID3) with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Score (ASDAS). A total of 341 consecutive AS patients who met the modified New York classification criteria were included. All patients completed BASDAI and RAPID3 at each visit, and their physicians completed physician global assessment. ASDASs were calculated using defined formulas. Proposed RAPID3 severity categories were compared to BASDAI and ASDAS categories. Spearman's rho correlation test and kappa statistics were used to analyze statistical significance. The median age of AS patients was 34.0 (21.0-69.0) years and the median disease duration 10.0 (2.0-35.0) years. Median scores for RAPID3, BASDAI, ASDAS-CRP, and ASDAS-ESR were 13.0 (0.0-27.3), 4.7 (0.0-9.7), 3.0 (0.4-5.8), and 2.5 (0.5-6.3), respectively. RAPID3 was strongly correlated with BASDAI and ASDAS-ESR (r = 0.842, r = 0.815; p < 0.001, respectively). Among the 209 patients with high disease activity according to BASDAI, 83.3 % had high or moderate severity according to RAPID3 (kappa 0.693; p < 0.001). Among the 133 patients with moderate, high, and very high disease activity on ASDAS-CRP, 91.7 % had high or moderate severity according to RAPID3 (kappa 0.548; p < 0.001). RAPID3 is as informative as BASDAI and ASDAS in our cohort of AS patients. We therefore suggest that RAPID3 may be used to assess the patient status quantitatively in AS patients, as part of routine care.

Patient-driven assessment of disease activity in Behçet's syndrome: cross-cultural adaptation, reliability and validity of the Turkish version of the Behçet's Syndrome Activity Score.

OBJECTIVES: The Behçet's Syndrome Activity Score (BSAS) is the first patient reported outcome measure developed to assess the global disease activity in patients with Behçet's syndrome (BS). We aimed to evaluate the reliability and validity of the Turkish version of BSAS for measuring disease activity in BS. We further investigated the performance of Routine Assessment of Patient Index Data (RAPID)3, a patient-reported index originally developed for rheumatoid arthritis, in BS patients. METHODS: Patients seen consecutively at a tertiary Rheumatology Centre were requested to complete BSAS and multidimensional health assessment questionnaire (MDHAQ). Besides, all attending physicians filled the Behçet's Disease Current Activity Form (BDCAF). Descriptive statistics and Pearson correlation coefficients were calculated accordingly for the reliability and validity assessments of BSAS. RESULTS: A total of 104 patients completed all three assessments. The test-retest reliability of BSAS has a good level (ICC=0.84, 95% CI [0.69-0.94]). The mean scores for BSAS, BDCAF and RAPID3 were 39±20.8, 3.2±1.4 and 9.2±5.6, respectively. BSAS was correlated with BDCAF moderately (r=0.587), while it was moderately correlated with RAPID3 (r=0.648). The correlation between the RAPID3 and BDCAF was moderate (r=0.403), but lower as compared to the correlations between the other instruments. CONCLUSIONS: We found that the BSAS has modest correlation with BDCAF and is a reliable and valid patient reported measure of disease activity that can be used to assess patients with BS. An outcome score composed of only patient-derived observations may have the additional advantage of being easier to use in a routine care setting. Demonstration of a moderate level of correlation between RAPID3 and BDCAF (close to the level of weak relationship), suggests that RAPID3 likely needs more investigations before recommending its use in BS.

Value of DWI in visual assessment of activity of sacroiliitis in longstanding ankylosing spondylitis patients.

OBJECTIVE: To test contrast to noise ratios (CNRs) of both diffusion-weighted (DW) images and contrast enhanced images in terms of the visual assessment of activity in sacroiliitis of ankylosing spondylitis (AS) patients. MATERIALS AND METHODS: The study included 21 patients with AS. All patients were examined with STIR, FST1/Gd and DWI (b = 0,600). A total of 54 hyperintense lesions on STIR were noted in their sacroiliac joints divided into four quadrants. CNRs were calculated for all of the sequences above. A second group of patients (n = 7) with normal sacroiliac joints (SIJs) served as controls. A total of 56 CNR measurements from apparently normal subchondral bone marrow in this control group were done as well. The differences between scores were tested for significance (SPSS version 17.0) using Wilcoxon's test in which p values lower than 0.01 were considered statistically significant. RESULTS: In the first group with sacroiliitis, mean CNRs for STIR, FST1/Gd, DWI were 32.97, 30.16 and 24.47, respectively. Mean CNRs in the second group with normal SIJs were calculated as 3.52 , 2.99 and 3.96, respectively . There was a statistically significant difference between the CNR measurements of the first and the second group (p = 0.000). Hyperintense lesions on STIR were depicted as "active" in the first group. Except for four lesions that were not included into the study, all of these hyperintense lesions were enhanced after contrast media administration. All of the "active" lesions were observed on DWI as well, at b = 600. No statistically significant difference between CNRs of contrast enhanced images and DWI and of contrast enhanced images and fluid sensitive sequences were found in the first group with sacroiliitis (p > 0.01). CONCLUSION: The CNRs are highest on STIR, followed by contrast enhanced images and DWIs. In terms of DWI and contrast enhanced images, there is no statistically significant difference between these two. Hence, contrast enhanced imaging can be replaced by DWI for visual analysis of active sacroiliitis, which is easy to apply without adverse affects of contrast media.
