    ABSTRACT: To assess the sequence and type of active joints in a cohort of newly diagnosed juvenile idiopathic arthritis (JIA) patients with full access to current treatment at first visit and during a follow-up period of 5-years, in order to identify an index joint/group of joints for magnetic resonance imaging in JIA. Patient charts of all consecutive newly diagnosed JIA patients with a follow-up duration of at least 5 years were analyzed. Patients were derived from two tertiary pediatric rheumatology centers. Patient characteristics and data concerning the presence of joints with arthritis and the use of medication were recorded. Findings from 95 JIA patients [39 (41 %) oligoarticular and 56 (59 %) polyarticular] were analyzed. At first visit, distribution of active joints among patients was as follows: knee (n = 70, 74 %), ankle (n = 55, 58 %), elbow (n = 23, 24 %), wrist (n = 23, 24 %), metacarpophalangeal (MCP) (n = 20, 21 %), proximal interphalangeal (PIP) (n = 13, 14 %), hip (n = 6, 6 %), shoulder (n = 5, 5 %), and distal interphalangeal (DIP) (n = 4, 4 %) joints. After a follow-up period of 5 years, the cumulative percentage of patients with specific joint involvement changed into: knee (n = 88, 93 %), ankle (n = 79, 83 %), elbow (n = 43, 45 %), wrist (n = 38, 40 %), MCP (n = 36, 38 %), PIP (n = 29, 31 %), shoulder (n = 20, 21 %), hip (n = 17, 19 %), and DIP (n = 9, 10 %) joints. Despite changes in treatment strategies over the years, the knee remains the most commonly involved joint at onset and during follow-up in JIA, followed by the ankle, elbow, and wrist. For the evaluation of outcome with MRI, the knee appears the most appropriate joint in JIA.

    ABSTRACT: The purpose of this study was to determine the effects of an oral preparation containing hyaluronic acid on osteoarthritic knee joint pain and function as well as changes in inflammatory cytokines, bradykinin, and leptin. We also used heavy water to determine the turnover rates of glycosaminoglycans in synovial fluid. This was a double-blind, randomized, placebo-controlled study of 40 subjects over a period of 3 months. Visual analog scale, Western Ontario McMaster pain, and WOMAC function scores were recorded. Serum and synovial fluid were measured by enzyme-linked immunosorbent assays for inflammatory cytokines, bradykinin, and leptin. In 20 subjects, terminal heavy water ingestion was used for spectral analyses of serum and joint fluid samples. There were statistically significant improvements in pain and function. Both serum and synovial fluid samples showed significant decreases for a majority of inflammatory cytokines, leptin, and bradykinin in the oral hyaluronic acid preparation group. Heavy water analyses revealed a significant decrease in hyaluronic acid turnover in the synovial fluid of the treatment group. A preparation containing hyaluronic acid and other glycosaminoglycans holds promise for a safe and effective agent for the treatment for patients with knee osteoarthritis and who are overweight. Further studies will be required to see whether this is a disease-modifying agent.

    ABSTRACT: The Ankylosing Spondylitis Work Instability Scale (AS-WIS) is a recently developed 20-item measure to assess work instability in AS. This study aimed to adapt the AS-WIS to Turkish and to test its reliability and validity. After the translation process, 132 AS patients were assessed by the AS-WIS, Bath AS Disease Activity Index, Bath AS Functional Index and the AS Quality of Life Questionnaire. Reliability was tested by internal consistency, person separation index (PSI) and intra-class correlation coefficient (ICC); internal construct validity by Rasch analysis; external construct validity by associations with comparator scales and cross-cultural validity by comparison with the original UK data. Reliability of the Turkish AS-WIS was good with Cronbach’s α and PSI of 0.88 and test–retest ICC of 0.91. Data showed good fit to Rasch model [mean item fit: −0.477 (SD 1.047), Chi-square interaction: 60.9 (df = 40, p = 0.018)]. There was no differential item functioning by age, gender, disease duration or work type. The scale was strictly unidimensional. 51 % of the patients were at moderate risk, and 9 % were at high risk of having to give up their work. External construct validity was confirmed by expected correlations with comparator scales, and a clear gradient of disease activity and functional status across increasing levels of risk. Cross-cultural validity showed some differences in item locations, but this cancelled out at the test level. Turkish version of the AS-WIS is reliable, valid and available for use in routine clinical setting to identify patients who are at risk of having to give up their current job.

    ABSTRACT: Performance of rheumatoid arthritis (RA) classification by the 2010 American College of Rheumatology (ACR)/European League against Rheumatism (EULAR) criteria, compared to the 1987 ACR criteria, has not been assessed in population-based cohorts in which disease identification is by mailed questionnaire. Women followed in the Nurses’ Health Study and Nurses’ Health Study II cohorts self-reported new doctor-diagnosed RA on biennial questionnaires. Two RA experts reviewed medical records of 128 new RA self-reports to obtain individual 1987 and 2010 criteria and arrived at a consensus opinion. We compared agreement in classification by the two criteria sets (kappa), and calculated sensitivity and specificity, with reviewers’ opinion as gold standard. Ninety-eight (77 %) participants were classified as RA by reviewers’ consensus opinion; 98 (77 %) fulfilled 1987 criteria, while 79 (63 %) fulfilled 2010 criteria. Seventy-two (56 %) were classified as RA by both sets, 21 (16 %) by neither, 26 (20 %) by only 1987 criteria, and 9 (7 %) by only 2010 criteria. Kappa for concordance was 0.36 (95 % CI 0.20–0.53). Compared to reviewer’s opinion, sensitivity and specificity were 0.93 and 0.77 for 1987 criteria, and 0.79 and 0.87 for 2010 criteria. Participants fulfilling 1987 criteria only were more likely to be seronegative. In these prospective population-based cohorts, significant discordance between 1987 ACR and 2010 ACR/EULAR criteria for classifying RA exists. Using the 2010 ACR/EULAR criteria alone had decreased sensitivity, and seronegative RA cases would be excluded in particular. Combined use of both will be necessary to maximize inclusion and allow sensitivity analyses.

    ABSTRACT: We described the recent spatial distribution of Rheumatoid arthritis in Turkey, and assessed the role of environmental variables in this distribution. We developed an observed RA incidence grid map by using geo-referenced Rheumatoid arthritis case data (2011) from the centres of 81 provinces and the kriging method with a spherical variogram model in geographic information systems (GIS). We also modelled Rheumatoid arthritis incidence in GIS by using complementary spatial database including the grid map layers of 14 environmental variables of Turkey. We conducted principle component analysis (PCA) and multiple regression to investigate relationships among variables and develop a model, respectively. The produced model was run in GIS to obtain a predicted (model) RA map. We tested the reliability of the model map by residual statistics, and found the model map dependable. Observed and model incidence maps revealed the geographic distribution of Rheumatoid arthritis cases in Turkey. The mean temperature, minimum temperature, maximum temperature, water vapour pressure, elevation, potential evapotranspiration, latitude, distance to seas, sunshine fraction, precipitation, longitude and aspect variables were found to have significant impacts on Rheumatoid arthritis. Consequently, the model incidence map established a good background to predict Rheumatoid arthritis cases following environmental changes.

    ABSTRACT: In Behçet’s disease, deep venous thrombosis occurs primarily in the lower extremities. Total recanalization rate is low, so thrombotic segment could be detected by imaging afterward. For disclosing vein involvement, leg swelling is commonly queried in the history taking in those patients. However, there are no data about the presence of “silent” thrombosis in patients with BD. We aimed at investigating the integrity of venous vessels in BD, without any known vascular event by using Doppler ultrasonography (DU). Patients having past events revealed in the vascular questionnaire or physical findings attributable to vascular disease were excluded. Various degree of venous insufficiency was detected in 74 patients in BD (74%), 24 out of 33 patients (72%) in AS and in 8 out of 34 (25%) in HC group. All were at the lower extremities, and there is no difference in the frequency between BD and AS, while both were significantly higher than in HC (P=0.001, and 0.004, respectively). Six patients with BD (6%) have chronic venous thrombi at the lower extremities and none in either AS and HC. As a non-invasive method, DU of lower extremities may disclose “silent” thrombosis. Venous insufficiency in those patients should be considered cautiously as an indicator of vein involvement. KeywordsBehçet’s disease–Deep-vein thrombosis–Doppler ultrasonography

    ABSTRACT: The objective of the study is to evaluate the short- and long-term effect of intraarticular sodium hyaluronate (SH) application in patients diagnosed with supraspinatus tendinitis (ST) that have shoulder pain on the clinical symptoms of the patients through comparison with conventional physiotherapy methods. A total of 24 patients were included in the study and were randomized into two groups.SH injection and physical therapy modalities (PTM) were administered to Group I and Group II, respectively. Home exercise programs were recommended to all of the patients in both groups. The patients were evaluated using the pain severity [Visual Analog Scale (VAS)], range of motion and functional evaluation (FE) parameters pertaining to pre-treatment, 3rd week, 3rd month and 4th year post-treatment. Patient’s global effectiveness (PGE) evaluation was performed in the 3rd month and 4th year of the treatment. There were no statistically significant differences for Group I’s resting VAS value between pre-treatment controls and controls in the 3rd week and 3rd month, no statistically significant differences were detected for Group II in passive flexion between pre-treatment and the 4th year, also in passive external rotation between pre-treatment and 3rd week (P>0.05). A statistically significant recovery was detected in both groups in all the other evaluation parameters (P<0.05). When evaluation was performed among groups, active abduction in the control in the 3rd month, VAS by movement and a statistically significant difference in favor of Group I in FE were determined (P<0.05). No statistically significant differences were found among groups in PGE (P>0.05). It was concluded that physical therapy modalities and SH application supplemented by home exercise programs were similar effects in short- and long term for ST which causes pain in shoulder and SH application may be a better alternative with regard to effectiveness and side effects for other treatment methods applied intraarticulary.

    ABSTRACT: In light of research carried out in recent years, it seems that aldosterone may produce a complex proinflammatory effect. Theoretically, excessive aldosterone release may stimulate the development and/or progression of autoimmune disorders. In this article, we report a case of a female in whom primary aldosteronism coexisted with Hashimoto’s thyroiditis. Surgical removal of an aldosterone-producing tumor improved thyroid function and decreased thyroid autoimmunity. We describe in details diagnostic and treatment strategies applied in our patient and their impact on the course and outcome of thyroiditis. We also present monocyte and lymphocyte cytokine release in the index subjects before and after surgical treatment. We conclude that primary aldosteronism may exacerbate the clinical course of autoimmune thyroiditis and probably also of other autoimmune disorders.
