Background : Secukinumab is a monoclonal antibody against interleukin 17 approved for patients with axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), and psoriasis. Treating axSpA and PsA patients with a history of malignancy is a challenge. While initial results on the applicability of secukinumab in this patient group are positive, the number of studies on this topic remains limited. This study aimed to investigate the drug's survival time and the efficacy and safety of secukinumab treatment in this specific patient group. Methods : This retrospective study included 30 patients with a history of malignancy who were followed up in rheumatology outpatient clinics in 12 centers throughout Turkey and treated with secukinumab between May 2018 and March 2024 with a diagnosis of axSpA and PsA. Results: The mean follow-up time was 29.8 ± 19.3 months. The drug retention rate was 89.7% after 12 months and 80.6% after 24 months. The most common tumor in our study was papillary thyroid carcinoma ( n = 5, 16.7%). During follow-up, local tumor recurrence was observed in a patient with urothelial carcinoma of the bladder. Conclusions : In the largest cohort reported to date, treatment with secukinumab in axSpA and PsA patients with a history of malignancy was not shown to cause oncologic recurrence except for one local tumor recurrence. Drug retention rates were also high, and disease activation and function improved compared to baseline. Therefore, secukinumab could be a safe and effective option for this patient group.

Background/objectives: Our aim was to validate the performance of the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria for antiphospholipid syndrome (APS), published in 2023, in an APS cohort., Methods: A total of 193 patients, 83 with APS (secondary APS, n = 45; primary APS, n = 38) and 110 without APS (systemic lupus erythematosus (SLE), n = 100; others, n = 10), were included in this study. The performance (sensitivity, specificity and area under the curve (AUC)) of the 2023 ACR/EULAR classification criteria for APS was evaluated and the agreement with the revised Sapporo criteria was compared using the kappa test., Results: In our cohort, the sensitivity and specificity of the 2023 ACR/EULAR classification criteria for APS were 73% and 94%, respectively (AUC: 0.836, 95% CI: 0.772-0.899), while the sensitivity and specificity of the revised Sapporo criteria were 66% and 98%, respectively (95% CI: 0.756-0.888). The performance of the two sets of criteria in our cohort was significantly consistent and significant ( p < 0.001). When the sensitivity, specificity and ROC curve analysis were performed again by excluding livedo racemosa, the sensitivity of the new criteria in our cohort was 62% and the specificity was 100% (AUC: 0.813, 95% CI: 0.746-0.881)., Conclusions: Although the newly published criteria broaden the scope of APS classification by including clinical findings other than thrombosis and obstetric criteria, their sensitivity in our cohort was low. On the other hand, we found that the specificity of the criteria in our cohort reached 100% when livedo findings were excluded., Competing Interests: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article.

Objectives: Post-thrombotic syndrome (PTS) is a frequent and important consequence of deep vein thrombosis (DVT) for Behcet`s disease (BD) patients. Although various clinical scales are used to diagnose PTS, Villalta scale was accepted as the standard tool to diagnose and grade the severity of PTS. Poor quality of life (Qol) in the general population was defined for patients with PTS, however, studies in BD patients with PTS is limited. Our aim was to compare the performance of different scales to assess venous disease in BD patients with a history of DVT and to assess the relationship with quality of life. Methods: Patients with BD ( n = 194, M/F:157/37, age:39.1 ± 9.5 years) with a DVT history were investigated. Villalta, VCSS,CEAP scale and SF 36,Veines scales were used to assess venous disease and QoL respectively. Results: Among BD patients, 120 (61.9 %) patients were classified as having PTS by Villalta and of patients 18% had severe PTS. Half of patients with CEAP score <4 were classified as having PTS. Also, 42% of patients with CEAP>4 and almost two third of VCSS classified severe CVD patients was grouped in severe PTS by Villalta scale. VCSS and Villalta classified PTS patients had decreased disease specific and general Qol scores compared to the patients without PTS. Also, severe PTS group (by VCSS) had decreased veines QoL scores and PCS compared to mild/moderate group. Conclusion: BD patients with DVT have a high risk of PTS. Our results show that both Villalta scale and VCSS should be used to assess venous disease BD patients with DVT. However, VCSS classified severity of PTS can show better correlation with venous disease -specific QoL., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Aim: This study aimed to evaluate the effect of the use of remineralization agents before the application of resin infiltration on the treatment of initial enamel lesions., Materials and Methods: Eighty buccal enamel samples were prepared from human molars, and artificial initial lesions were formed after 96 h of incubation with a demineralizing solution. The samples were randomly divided into 8 groups (n = 10) including a remineralizing agent (Tooth Mousse, Medical Mineral Gel, Remin Pro), resin infiltration (ICON), and a combined treatment of both. Remineralizing agents were applied in pH cycle for 7 days. Baseline, demineralization, and after-treatment fluorescence (FluoreCam and DIAGNOdent Pen), surface microhardness (HMV-2T), surface roughness (M300C), OCT (Maestro-2) and ultrasonic system (Novascope 4500) data were obtained for all groups. The sample surfaces were examined under SEM/EDX (SU3500) at x1000. Data were statistically analyzed using the Two-Way Robust ANOVA and Bonferroni tests (p < 0.05)., Results: There was no statistically significant difference between the groups for microhardness, roughness, OCT, DIAGNOdent Pen, ultrasound, and FluoreCam size/intensity values (p = 0.582; p = 0.963; p = 0.884; p = 0.923; p = 0.051; p = 0.268; p = 0.793 respectively). The effect of the treatment procedure showed a significant difference (p < 0.001), except for the roughness values (p = 0.984). The lowest Calcium (Ca) ratio (%atomic) was observed in the RI group in the EDX analysis., Conclusion: Remineralizing agents and resin infiltration methods may be used in combination or alone in the treatment of initial enamel lesions. Combining remineralizing agents with resin infiltration does not alter the efficacy of the treatment., (© 2024. The Author(s).)

Patients with axial spondyloarthritis (axSpA) who receive immunosuppressive therapy are at risk of infection due to impaired immune function and immunosuppressive medication. Vaccination plays a crucial role in preventing infections in this population. However, vaccination rates and factors influencing vaccination uptake in axSpA patients still need to be adequately studied. This study was designed to determine the vaccination rates of vaccines covered by health insurance in this particular group in Turkey and attitudes towards vaccines and infections. This survey included 199 patients with axSpA who visited our outpatient clinic in June, July, and August 2023 and received biologic and targeted synthetic disease-modifying antirheumatic drugs. The mean age of the participants was 43.7 ± 0.7 years, and the majority were male (66.3%). The majority of the patients were vaccinated against COVID-19 (85.4%), followed by hepatitis B (41.2%), influenza (20.1%), and pneumococcal pneumonia (10.5%). While awareness of COVID-19 vaccination was widespread (100%), knowledge of other vaccines was lower (hepatitis B 80.9%, influenza 70.3%, pneumococcal 60.3%, respectively). Educational interventions targeting patients and healthcare professionals are needed to improve vaccination rates in this population. Our findings emphasize the need for strategies to increase vaccination rates in axSpA patients receiving immunosuppressive therapy. Removing barriers to vaccination and raising awareness of the importance of vaccination are critical to optimizing vaccination practices in this vulnerable population.

Purpose: This study aimed to evaluate the enamel remineralization efficacy of enamel matrix derivative (EMD), experimental bioactive glass (BAG), and fluoride varnish in vitro., Methods and Materials: Artificial initial caries lesions were developed on fifty human enamel specimens using demineralization solution (pH 4.5, 37°C, 96 hours). Specimens were randomly assigned to five groups (n=10): I-5% NaF varnish (Enamelast), II-experimental 58S5 BAG+37% phosphoric acid (PA), III-EMD (Emdogain) + Ethylenediaminetetraacetic Acid (EDTA), IV-EMD+37% PA, V-Control (untreated). All remineralization agents were applied with pH cycling for seven days. The specimens were scanned by spectral domain optical coherence tomography (SD-OCT) at baseline, at demineralization, and after pH cycling. Lesion depths were measured using image analysis software (ImageJ). Lesions were evaluated using surface microhardness (SMH) and two fluorescence methods (FluoreCam and DIAGNOdent Pen [DDPen]). The data were statistically analyzed by Kruskal Wallis, Friedman, and Wilcoxon tests (α=0.05)., Results: According to SD-OCT results, fluoride varnish was found to be the most effective agent in reducing lesion depth (p=0.005). All agents increased the SMH values after pH cycling. No significant difference was found among fluoride varnish, BAG, and EMD+PA groups. These SMH values were significantly higher than EMD+EDTA and control groups (p<0.001). All groups showed lower DDPen scores compared with the control group (p<0.001), however, no significant difference was found among the remineralization agents. In FluoreCam assessment, size and intensity values of all treated groups showed improvement. However, there was no significant difference between the treatment groups in terms of FluoreCam size measurements (p=0.186)., Conclusion: 58S5 BAG and EMD+PA have remineralization capacity as effective as fluoride varnish. EMD+PA showed better SMH and lesion intensity results than EMD+EDTA., (©Operative Dentistry, 2024.)

Objective: In our study, we analyzed the efficacy and safety data of patients with systemic lupus erythematosus (SLE) after switching to biosimilar rituximab (RTX)., Patients and Methods: Twenty-two patients who switched to RTX were included in the study. Efficacy data were analyzed using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score, and safety data were analyzed using the frequency of side effects., Results: The mean treatment duration of originator RTX was 35.6 ± 23.0 months, and the median treatment duration of biosimilar RTX was 17 months. The SLEDAI-2K score, approximately three months after the first dose of biosimilar RTX, was significantly lower (p = 0.027). A statistically significant difference was found between the SLEDAI-2K score assessed at the follow-up visit three months after the last dose of originator RTX and the SLEDAI-2K score obtained approximately three months after the first dose of biosimilar RTX (p = 0.011) and the calculated median SLEDAI-2K score was significantly lower than the SLEDAI-2K score assessed after administration of originator RTX. The side effect frequency that developed during the treatment of originator RTX was 15.3 per 100 patient-years. The most common side effect was infection, which was 15.3 per 100 patient-years. The most frequent infection was urinary tract infection. The side effect frequency during treatment of biosimilar RTX was 39 per 100 patient-years, and the most frequent infection was pneumonia., Conclusions: In our study, SLEDAI-2K scores demonstrated that no efficacy loss was experienced after switching to CT-P10 molecule, which is a biosimilar RTX. It was observed that switching to biosimilar RTX did not decrease treatment efficacy in the patient group diagnosed with SLE and biosimilar RTX was found to be safe.

Objectives: This study aims to investigate the effect of age on disease activity and biological treatment in patients with ankylosing spondylitis (AS)., Patients and Methods: A total of 811 AS patients registered in the TURKBIO registry database between 2011 and 2019 were categorized according to their age at the time of entry into the registry and assigned to one of two groups: young patients, defined as <60 years of age (n=610), and those aged ≥60 years (n=201) were recorded as elderly patients. Demographic, clinical, and laboratory characteristics, along with disease activity markers and other follow-up parameters, as well as current and prior treatments, were electronically recorded during each visit using open-source software., Results: The mean age of the elderly patients was 67±5.8 years, while the mean age of the younger patients was 49.2±10.9 years. Male predominance was lower in the older AS group compared to the younger AS group (p=0.002). During follow-up period, 397 patients (comprising 318 young and 79 elderly individuals) had a history of using at least one biological disease-modifying agent (bDMARD). There was no significant difference between the groups in terms of DMARD and bDMARD-use distributions. First tumor necrosis factor inhibitor (TNFi) retention rates were found to be similar in both groups over 10 years of follow-up. Adverse events were found to be similar in young (19.9%) and elderly (26.8%) AS patients., Conclusion: Research in the TURKBIO cohort reveals that both older and younger patients with AS exhibited similar disease activity levels with comparable treatment approaches. Moreover, the results of TNFi treatments in elderly patients were the same as those observed in younger patients, with no notable increase in safety concerns., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2024, Turkish League Against Rheumatism.)

Familial Mediterranean fever (FMF) is characterized by recurrent episodes of fever and serositis. Blood-based biomarkers determined in FMF patients during attack-free periods could be used to predict the risk of amyloidosis and the severity of the disease. The recently defined pan-immune-inflammation value (PIV) comprises four distinct subsets of blood cells and serves as an easily accessible and cost-effective marker. The objective of this study was to assess the role of PIV in predicting amyloidosis and moderate-to-severe disease. Clinical characteristics and laboratory values during the attack-free period were retrospectively analyzed in 321 patients over 18 years of age diagnosed with familial Mediterranean fever (FMF). In our tertiary adult rheumatology outpatient clinic, disease severity and laboratory markers were evaluated during the first attack-free interval. At baseline, patients with amyloidosis were excluded. Patients were categorized based on the presence of amyloidosis and the severity of the disease. When focusing on amyloidosis in receiver operating characteristic (ROC) analysis, optimal cut-off values for pan-immune-inflammation value (PIV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio were determined as ≥518.1, ≥2.3, and ≥127.2, respectively. In multivariate analysis, PIV, C-reactive protein (CRP), and the presence of the M694V homozygous mutation emerged as independent risk factors for both amyloidosis and moderate-to-severe disease. Additionally, NLR was identified as an independent risk factor for amyloidosis, while red blood cell distribution width was associated with moderate-to-severe disease. In patients with FMF, especially in the presence of the M694V homozygous mutation, CRP and PIV may be useful in predicting both amyloidosis and moderate-to-severe disease.

Background/objectives: YouTube is increasingly being used as an educational tool and is a substantial source of information. This study aimed to assess the quality of the most viewed YouTube videos pertaining to familial Mediterranean fever (FMF)., Methods: A search on YouTube was conducted on January 13, 2022, using the keywords: "familial Mediterranean fever treatment," "familial Mediterranean fever colchicine," and "familial Mediterranean fever colchicine opacalcium." Two rheumatologists independently evaluated the relevance and accuracy of the videos. Redundant or irrelevant videos were excluded. The educational value of YouTube videos was assessed using the Global Quality Scale (GQS). Comparative analyses of video parameters across different cohorts were performed. To assess the reliability and quality of the videos, a modified version of the DISCERN scale and the GQS were employed., Results: Out of the 59 videos reviewed, 43 (72.9%) were of high quality, 10 (16.9%) were of medium quality, and 6 (10.2%) were of low quality. Upon comparing parameters among groups, no significant disparities were observed in terms of daily views, daily favorites, daily dislikes, or daily comments ( p  > 0.05). GQS scores for usefulness and modified DISCERN scores showed significant differences among groups ( p  < 0.001). Additionally, both GQS and modified DISCERN scores exhibited moderately negative correlations ( r  =  - .450 and r  =  - .474, respectively) and high statistical significance ( p  < 0.001 for both) with utility assessment., Conclusion: YouTube is a valuable repository of high-quality videos for FMF patients. Healthcare providers should guide their patients to high-quality video sources to supplement their educational material., Competing Interests: The authors declare there are no competing interests., (©2024 Coşkun et al.)

Introduction: Idiopathic granulomatous mastitis (IGM) is a rarely seen chronic and benign disease of the breast. IGM usually emerges in women between 30 and 45 years of age and within the first 5 years after lactation. There is no consensus on the treatment of the disease. Steroids, immunosuppressive agents such as methotrexate and azathioprine, antibiotics, and surgical and conservative treatments can be preferred. In the present study, it was aimed to demonstrate the treatment options and follow-up data of the patients with IGM and to investigate the effective factors on recurrence if developed in the follow-up period., Materials and Method: The data of 120 patients diagnosed with idiopathic granulomatous mastitis were evaluated for this cross-sectional retrospective study. The demographic, clinical, treatment, and follow-up features of the patients were obtained from the file records., Results: The median age value of the 120 female patients included in the study was 35 (24-67) years. Of the patients, 45%, 79.2%, 49.2%, and 15% had a past history of surgical intervention, steroid use, methotrexate use, and azathioprine use, respectively. Recurrent lesion developed after the treatment in 57 (47.5%) patients. The recurrence rate was 66.1% in the patients who underwent surgical intervention in the initial treatment. There was a statistically significant difference between the patients with and without recurrence regarding the presence of abscess, the presence of recurrent abscess, and having surgical intervention as the initial treatment in the past history. The rate of having surgery was statistically significantly higher compared with the administration of steroid therapy alone and the combination of steroid and immunosuppressive therapy in the initial treatment of the patients who developed recurrence. The rate of having surgery together with the administration of steroid and immunosuppressive therapy was statistically significantly higher than the administration of steroid and immunosuppressive therapies., Discussion: Our study showed that surgical intervention and the presence of abscess increased recurrence in the treatment of IGM. Key Points • This study has shown that surgical intervention and the presence of abscess increase recurrence. • A multidisciplinary approach to the treatment of IGM and management of the disease by the rheumatologists may be critical., (© 2023.

Tocilizumab (TCZ) is a recombinant humanized monoclonal antibody that targets the IL-6 receptor. TCZ found to be efficacious and has a good tolerated safety profile in rheumatoid arthritis (RA) patients. The aim of this study was to describe the disease activity and retention rate in Turkish RA patients who were prescribed TCZ as first-line biologic treatment in a real-world setting. Secondary data obtained from adult RA patients' files was used in a multicenter and retrospective context. Clinical Disease Activity Index (CDAI), Disease Activity Score in 28 joints with ESR (DAS28-ESR), and retention rates of TCZ were evaluated at related time points. 130 patients (87.7% female) with a mean age of 53 years (SD; 15.0) were included in the study. Mean RA duration was 14 years and median duration of follow-up was 18.5 months. Number of patients with ongoing TCZ treatment at 6, 12, and 24 months were 121 (93%), 85 (65%), and 46 (35%), respectively. Remission rates at 6, 12, and 24 months per CDAI (< 2.8) and DAS28-ESR (< 2.6) scores were 61.5, 44.6, 30%, and 54.6, 40.8, 27.7%, respectively. Both CDAI and DAS28-ESR scores significantly improved at 6, 12 and 24 months (p < 0.001 for both). At 24 months, 23 patients (17.6%) discontinued TCZ, of whom majority (17/23) were due to unsatisfactory response. Retention rates of TCZ at 6, 12, and 24 months were 93, 84.3, and 72.2%, respectively. In this real-world study, TCZ as a first-line biologic therapy was found to be efficacious and showing high retention rates. These real-world study results are in line with previous randomized studies., (© 2022. The Author(s).)

This study aimed to compare Tuberculin Skin Test (TST) and QuantiFERON®-TB Gold In-Tube (QFT-GIT) test in rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients scheduled for biological and targeted synthetic disease modifying anti-rheumatic drugs (DMARDs) in a Bacillus Calmette-Guérin-vaccinated population. Adult RA (n = 206) and SpA (n = 392) patients from the TReasure database who had both TST and QFT-GIT prior to initiation of biological and targeted synthetic DMARDs were included in the study. Demographic and disease characteristics along with pre-biologic DMARD and steroid use were recorded. The distribution of TST and performance with respect to QFT-GIT were compared between RA and SpA groups. Pre-biologic conventional DMARD and steroid use was higher in the RA group. TST positivity rates were 44.2% in RA and 69.1% in SpA for a 5 mm cutoff (p < 0.001). Only 8.9% and 15% of the patients with RA and SpA, respectively, tested positive by QFT-GIT. The two tests poorly agreed in both groups at a TST cutoff of 5 mm and increasing the TST cutoff only slightly increased the agreement. Among age, sex, education and smoking status, pre-biologic steroid and conventional DMARD use, disease group, and QFT-GIT positivity, which were associated with a 5 mm or higher TST, only disease group (SpA) and QFT-GIT positivity remained significant in multiple logistic regression. TST positivity was more pronounced in SpA compared to that in RA and this was not explainable by pre-biologic DMARD and steroid use. The agreement of TST with QFT-GIT was poor in both groups. Using a 5 mm TST cutoff for both diseases could result in overestimating LTBI in SpA., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Objective: The coronavirus disease 2019 pandemic has been resulting in increased hospital occupancy rates. Rheumatic patients cannot still reach to hospitals, or they hesitate about going to a hospital even they are able to reach. We aimed to show the effect of the first wave of coronavirus disease 2019 pandemic on the treatment of biological disease-modifying anti-rheumatic drugs in patients with rheumatoid arthritis or spondyloarthritis., Methods: Patients were divided into three groups as follows: pre-pandemic (Pre-p: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within 6 months before March 11, 2020); post-pandemic A (Post-p A: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the first 6 months after March 11, 2020); post-pandemic B (Post-p B: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the second 6 months)., Results: The number of rheumatoid arthritis patients in the Post-p A and B groups decreased by 51% and 48%, respectively, as compared to the Pre-p group similar rates of reduction were also determined in the number of spondyloarthritis patients. The rates of tofacitinib and abatacept use increased in rheumatoid arthritis patients in Post-p period., Conclusion: The number of rheumatoid arthritis and spondyloarthritis patients starting on biological disease-modifying anti-rheumatic drugs for the first time decreased during the first year of the coronavirus disease 2019 pandemic.

Objective: This study aims to examine the efficacy and safety of the antitumor necrosis factor (TNF) drugs in ankylosing spondylitis (AS) patients with chronic kidney disease., Methods: In this study, 24 male patients with a glomerular filtration rate (GFR) of <60 mL min􏰁1 1.73 m􏰁2 were included among 863 patients who were followed-up once in 3 months regularly from 2010 to 2018years. Twenty-four patients were chosen for the control group among 420 male patients whose renal functions were normal using random sampling. We examined C-reactive protein, erythro- cyte sedimentation rate, serum creatinine, and GFR values, and also the measurements of Bath Anky- losing Spondylitis Disease Activity Index (BASDAI) were recorded at the beginning of the treatment with anti-TNF agents and in the 3rd, 6th, 9th, 12th, and final visit months., Results: Eleven (45.9%) of the patients included in the study were in the routine dialysis program. The initial anti-TNF treatments were etanercept (62.5%), infliximab (16.7%), adalimumab (16.7%), and goli- mumab (4.1%). Treatment was effective in 22 (91.7%) of the patients. When the values of the two groups' patients were compared at the beginning of the treatment, there was a substantial reduction regarding BASDAI (P < .001). Pleural effusion, infective endocarditis, septic arthritis, and prosthesis infection were major side effects (n 1⁄4 4). The mortality rate of the 24 patients was 29.2% (n 1⁄4 7)., Conclusion: This study demonstrated that anti-TNF drug treatment is effective and safe in patients with AS who have chronic kidney disease.

Objective: TURKBIO registry, established in 2011, is the first nationwide biological database in Turkey. This study aimed to provide an overview of TURKBIO data collected by June 2018., Methods: The registry included adult patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), nonradiographic axial spondyloarthritis (nr-AxSpA), and psoriatic arthritis (PsA). Demographic and clinical features, disease activity markers, and other follow-up parameters, current and previous treat- ments, and adverse events were registered electronically at each visit using open-source software. The registration of patient-reported outcome measures was carried out electronically by the patients using touch screens., Results: TURKBIO registry included a total of 41,145 treatment series with biologicals. There were 2,588 patients with axSpA (2,459 AS and 129 nr-axSpA), 2,036 with RA, and 428 with PsA. The total number of patients, including those with other diagnoses, was 5,718. In the follow-up period, the number of patients and also visits steadily increased by years. The yearly mean number of visits per patient was found to be 2.3. Significant improvements in disease activity and health assessment parameters were observed following the biological treatments. Biologics were often given in combination with a con- ventional synthetic disease-modifying antirheumatic drug in patients with RA. Infections were the most commonly seen adverse events, followed by allergic reactions. Tuberculosis was observed in 12 patients, malignancy in 18, and treatment-related mortality in 31., Conclusion: TURKBIO provided a valuable real-life experience with the use of biologics in rheumatic diseases in Turkey.

Purpose: Spondyloarthritis (SpA) is a group of diseases with overlapping skeletal and extra-articular features. Acute anterior uveitis (AAU) is the most common extra-articular manifestation of SpA. The relation between AAU and SpA is well defined in the current literature. Our study aims to analyze the frequency and factors associated with AAU in different forms of SpA in a large nationwide cohort of Turkish SpA patients., Design: Retrospective cohort study., Methods: The data were obtained from the TReasure database, which compiles data from records of the web-based Rheumatoid Arthritis (RA) and SpA patients treated with biological disease-modifying anti-rheumatismal drugs from different regions of Turkey. The clinical characteristics of SpA and uveitis are recorded., Results: Data of the 4,297 SpA patients were included in the study. Overall, 475 of 4,297 patients (11.0%) had experienced 1 or more episodes of uveitis. SpA patients with older age (P < .001), a smoking history (P = .004), delayed diagnosis (P = .001), longer disease duration (P < .001), arthritis (P < .001), positive HLA-B27 (P < .001), a family history of SpA (P < .001), and radiographic damage (presence of sacroiliitis, syndesmophytes, bamboo spine, hip involvement) (P < .001 for all) more commonly had uveitis. On the other hand, uveitis was less prevalent in patients with psoriasis and psoriatic arthritis (P < .001 for both)., Conclusion: Uveitis may be the key feature leading to SpA diagnosis. Patients with radiographic damage and long disease duration have an increased risk for uveitis in both male and female SpA patients. Patients with uveitis should be referred to a rheumatologist for a thorough evaluation of SpA., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objective: Fasting may lead to some problems in patients who have to use drugs on a regular and continuous basis. The objective of this study is to identify rheumatology patients' attitudes toward Ramadan and fasting., Method: The descriptive and cross-sectional study was conducted with 374 patients. The study data were collected using a questionnaire form. SPSS was used and percentage and Chi-square analyses were performed., Results: It was determined that 56.1% fasted during Ramadan. When asked about the effect of fasting on the disease, 88.4% of those who fasted answered "it had no effect", and 80.1% of those that did not fast said "it affected negatively" (P < .05). It was determined that 41.9% of the fasting patients did not visit the doctor during Ramadan, 52.9% continued using their drugs without any change, and 73.3% did not ask for information on fasting. The rate of patients who were informed by the doctor without any request for information was found to be only 9% (P < .05)., Conclusion: It was determined that more than half of the rheumatology patients fasted, the majority of these patients thought that it would not affect their disease, and the rate of request for information from the doctor was low. It is considered that a drug program could be prepared for fasting individuals who are willing to fast, in which drugs are taken between the İftar and Suhur times, and patients can safely fast without any additional risk to their disease., (© 2020 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Ankylosing spondylitis (AS) is a highly heritable immune-mediated arthritis common in Turkish and Iranian populations. Familial Mediterranean Fever (FMF) is an autosomal recessive autoinflammatory disease most common in people of Mediterranean origin. MEFV, an FMF-associated gene, is also a candidate gene for AS. We aimed to identify AS susceptibility loci and also examine the association between MEFV and AS in Turkish and Iranian cohorts. We performed genome-wide association studies in 1001 Turkish AS patients and 1011 Turkish controls, and 479 Iranian AS patients and 830 Iranian controls. Serum IL-1β, IL-17 and IL-23 cytokine levels were quantified in Turkish samples. An association of major effect was observed with a novel rare coding variant in MEFV in the Turkish cohort (rs61752717, M694V, OR = 5.3, P = 7.63×10(-12)), Iranian cohort (OR = 2.9, P = 0.042), and combined dataset (OR = 5.1, P = 1.65×10(-13)). 99.6% of Turkish AS cases, and 96% of those carrying MEFV rs61752717 variants, did not have FMF. In Turkish subjects, the association of rs61752717 was particularly strong in HLA-B27-negative cases (OR = 7.8, P = 8.93×10(-15)), but also positive in HLA-B27-positive cases (OR = 4.3, P = 7.69×10(-8)). Serum IL-1β, IL-17 and IL-23 levels were higher in AS cases than controls. Among AS cases, serum IL-1β and IL-23 levels were increased in MEFV 694V carriers compared with non-carriers. Our data suggest that FMF and AS have overlapping aetiopathogenic mechanisms. Functionally important MEFV mutations, such as M694V, lead to dysregulated inflammasome function and excessive IL-1β function. As IL-1 inhibition is effective in FMF, AS cases carrying FMF-associated MEFV variants may benefit from such therapy., Competing Interests: The authors have declared that no competing interests exist.

Objective: The aim of this study is to evaluate the effects of different fiber insertion techniques and thermomechanical aging on the fracture resistance of endodontically treated mandibular premolar teeth restored using bulk-fill composites., Materials and Methods: Eighty human mandibular premolar teeth were randomly divided into eight groups: Group IN, Group BF, Group PRF1, Group PRF2, Group IN-TMA, Group BF-TMA, Group PRF1-TMA ,and Group PRF2-TMA. Group IN (intact) and Group IN-TMA (intact but subjected to thermomechanical aging) served as control groups. In the other six groups, endodontic treatment was performed and standardized mesio-occluso-distal (MOD) cavities were prepared. In BF, PRF1, and PRF2, the cavities were restored with bulk-fill composite only, bulk-fill/Ribbond, and bulk-fill/additional Ribbond, respectively. In BF-TMA, PRF1-TMA, and PRF2-TMA, the teeth were subjected to thermomechanical aging after the restorations. All of the teeth were fractured on the universal testing machine. Fracture surfaces were analyzed with a stereomicroscope., Results: Control groups showed significantly higher fracture strengths than tested groups ( P <0.05). No statistically significant difference was observed among the tested groups ( P >0.05). Most of the favorable fractures were seen in PRF1, PRF2, and PRF2-TMA. Most of the unfavorable fractures were seen in BF-TMA., Conclusions: Although fiber insertion with different techniques did not increase the fracture strength of teeth restored with bulk-fill composites, it increased the favorable fracture modes. Thermomechanical aging did not change the fracture strength of the groups.

Objective: The purpose of this study was to determine the fracture strength of endodontically treated mandibular premolar teeth restored with composites and different reinforcement techniques., Methods and Materials: Forty-eight freshly extracted human mandibular premolar teeth were randomly divided into four groups: group IN, group CR, group FRC, and group PRF. Group IN consisted of teeth with intact crowns and served as the control group. In the other three groups, endodontic treatment was performed and standard mesio-occluso-distal (MOD) cavities were prepared. Then cavities were restored with hybrid resin composite only, flowable composite and hybrid resin composite, and Ribbond, flowable composite and hybrid resin composite in groups CR, FRC and PRF, respectively. All of the teeth were subjected to fracture by means of a universal testing machine, and compressive force was applied with a modified stainless-steel ball at a crosshead speed at 0.5 mm/min., Results: The highest values were observed in group IN, while the lowest values were determined in group CR. There was not any statistically significant difference between group CR and group FCR ( p>0.05). When groups CR, FCR, and PRF were compared, group PRF showed significantly better fracture strength than did groups CR and FCR ( p<0.05). It was determined that there was not any significant difference between group IN and group PRF ( p>0.05)., Conclusions: Polyethylene ribbon fiber considerably increases the fracture strength of mandibular premolar teeth with MOD cavities restored with composite.

Patients with primary Sjogren's syndrome (pSS) may go undiagnosed or be misclassified due to the insidious nature and wide spectrum of the disease. The available several classification criteria emphasize glandular findings. We aimed to analyze the efficiency of various classification criteria sets in patients diagnosed on the clinical basis by expert opinion and to compare those pSS patients who fulfilled these criteria with those who did not. This is a multicenter study in which 834 patients from 22 university-based rheumatology clinics are included. Diagnosis of pSS was made on the clinical basis by the expert opinion. In this study, we only interviewed patients once and collected available data from the medical records. The European criteria, American-European Consensus Group (AECG) and American College of Rheumatology (ACR) Sjogren's criteria were applied. Majority of the patients were women (F/M was 20/1). The median duration from the first pSS-related symptom to diagnosis was significantly shorter in men (2.5 ± 2.3 vs 4.3 ± 5.9 years) (p = 0 < 0.016). When the European, AECG and ACR Sjogren's criteria were applied, 666 patients (79.9%) satisfied at least one of them. In total, 539 patients (64.4%) satisfied the European, 439 (52.6%) satisfied the AECG, and 359 (43%) satisfied the ACR criteria. Among the entire group, 250 patients (29.9%) satisfied all and 168 (20.1%) met none of the criteria. The rates of extraglandular organ involvements were not different between patients who met at least one of the criteria sets and those who met none. There is an urgent need for the modification of the pSS criteria sets to prevent exclusion of patients with extraglandular involvements as the dominant clinical features.

Objective: Rheumatoid factor (RF) positivity that may occur in a number of patients with hepatitis B (HBV) infection poses challenges in terms of differential diagnosis with rheumatoid arthritis (RA). On the other hand, antibodies to cyclic citrullinated peptide (anti-CCP) may prove to be an important marker for differential diagnosis of the two conditions. This study aimed to assess anti-CCP and RF positivity among patients with hepatitis B and rheumatoid arthritis., Material and Methods: Anti-CCP and RF seropositivity was assessed in 61 patients with HBV infection (32 patients with chronic hepatitis, 29 patients with inactive HBV carrier status) and 40 patients with RA as the control group., Results: RF positivity was found in 18.7% and 34.4% of the patients with chronic hepatitis B and inactive HBV carrier status, respectively. On the other hand, only one patient with chronic HBV had low positive anti-CCP. RF was positive in 24 (60%) and anti-CCP was positive in 26 (65%) patients among the 40 patients with RA., Conclusion: Anti-CCP may be helpful in the differential diagnosis between RA and chronic HBV infection or inactive HBV carrier status.

Polymyalgia rheumatica (PMR) is an inflammatory disease of individuals aged over 50 years. Because of the concomitant malignancy possibility and the high prevalence of constitutional symptoms seen in this condition, patients with classical clinical picture often experience delay in diagnosis and treatment and are exposed to a wide list of laboratory and imaging procedures. In this study, we aimed to explore the adventure these patients experience from symptom onset to rheumatology clinic. A total of 106 PMR patients (84 women, 22 men) mean age 70.1 ± 8 were analyzed retrospectively. The time period from the onset of symptoms and referral to rheumatology specialists was explored. Diagnostic methods applied to these patients, antibiotic use and hospitalization during this period were recorded. The interval between the onset of the symptoms and admission to rheumatology unit was 13 ± 13 months. In this period, abdominal computed tomography (29.2 %), chest computed tomography (21.7 %), cranial magnetic resonance imaging (18.9 %) and whole-body scintigraphy (3.8 %) were applied to the patients. About 30 % of the patients were hospitalized for a mean period of 7 ± 3 days before referral to rheumatology unit, and 30 % of the patients were given antibiotics. In order to reduce the delay in the diagnosis of PMR and prevent unnecessary and expensive diagnostic methods, education of clinicians about the diagnosis of PMR may be beneficial.

Objective: Neutrophil lymphocyte ratio (NLR) has emerged as a valuable and reliable method for follow-up of systemic inflammatory disease. We herein aimed to evaluate the role of NLR in the clinical follow-up of inflammation and also to compare its relationship with other measures, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)., Material and Methods: A total of 35 active ankylosing spondylitis (AS) and 38 healthy volunteers were included in the study. The patient group was enrolled for treatment with one anti-tumor necrosis factor (TNF) drug. Total blood count, ESR, CRP, and BASDAI score were obtained before and 3 months following the treatment. NLR was found with a mathematical calculation of the ratio of neutrophils with lymphocytes., Results: The mean NLR value of the control group and patients was 1.90±0.89 and 2.67±1.17, respectively (p<0.05). After a 3-month course of treatment, the patient group had a mean NLR value of 1.8±0.7, which was significantly lower than pretreatment values (p<0.001). The post-treatment mean ESR, CRP, and BASDAI scores were significantly lower than mean baseline scores (p<0.001, p=0.007, p<0.001, respectively). Also, NLR was found to be correlated with BASDAI, ESR, and CRP (r=0.388, p<0.001; r=0.455, p<0.0001; and r=0.3389, p<0.005, respectively)., Conclusion: Neutrophil lymphocyte ratio could be a reliable and easily accessible method for follow-up of patients with AS.
