Validity and reliability of the Duruöz Hand Index in patients with psoriatic arthritis.

OBJECTIVE: The Duruöz Hand Index (DHI) is a valuable scale developed for evaluating hand functions of patients with rheumatoid arthritis and subsequently proven to be valid and reliable in various diseases. This study aims to investigate the validity and reliability of the DHI in patients with psoriatic arthritis (PsA). METHODS: Patients diagnosed with PsA according to CASPAR criteria were enrolled. The demographic, clinical, and functional characteristics of patients were evaluated. Functional assessment was performed with DHI, Hand Functional Index, Health Assessment Questionnaire, and VAS-disability scale. C-reactive protein level, patients' and physicians' global VAS, swelling and tenderness of the hand joints, gross grip strength and thumb strength, and disease activity assessments were recorded as non-functional parameters related to active disease status. Reliability was assessed by internal consistency (with Cronbach's-a) and test-retest intraclass correlation coefficient. Face, content, convergent, and divergent validities were applied. RESULTS: One hundred and forty-four patients (74.3% female) were included in this study. The Cronbach's alpha coefficient was 0.963, and for the test-retest reliability of the DHI, the intraclass correlation coefficient was 0.904 (p < 0.001). DHI showed good correlations with the functional disability scales (Hand Functional Index, Health Assessment Questionnaire, VAS-disability), indicating its convergent validity and moderate to non-significant correlations with the non-functional parameters supporting its divergent validity. CONCLUSIONS: Despite the occurrence of significant deformities and functional loss in PsA patients, there is a noticeable absence of specific tools tailored for PsA. Considering the intricacies associated with skin, nail, tendon, entheseal involvement, and arthritis, there is a need for straightforward tools in both clinical practice and studies involving patients with PsA. The DHI is a valid and reliable scale to evaluate the functional disability of hands in patients with PsA.

Prevalence of cardiovascular diseases and traditional cardiovascular risk factors in patients with rheumatoid arthritis: a real-life evidence from BioSTAR nationwide registry.

Patients with rheumatoid arthritis (RA) have increased morbidity and mortality due to cardiovascular (CV) comorbidities. The association of CV diseases (CVD) and traditional CV risk factors has been debated, depending on patient and RA characteristics. This study aimed to find the prevalence of CVD and CV risk factors in patients with RA. A multi-center cross-sectional study was performed on RA patients using the BioSTAR (Biological and Targeted Synthetic Disease-Modifying Antirheumatic Drugs Registry) in September 2022. Socio-demographic, clinical, and follow-up data were collected. Myocardial infarction, ischemic heart disease, peripheral vascular disorders, congestive heart failure, ischemic stroke, and transient ischemic attack were regarded as major adverse cardiovascular events (MACEs). CVD was defined as the presence of at least one clinical situation of MACE. Group 1 and Group 2 included patients with and without CVD. Prevalence rates of CVD and traditional CV risk factors were the primary outcomes. Secondary outcomes were the differences in the clinical characteristics between patients with and without CVD. An analysis of 724 patients with a mean age of 55.1 ± 12.8 years diagnosed with RA was conducted. There was a female preponderance (79.6%). The prevalence rate of CVD was 4.6% (n = 33). The frequencies of the diseases in the MACE category were ischemic heart disease in 27, congestive heart failure in five, peripheral vascular disorders in three, and cerebrovascular events in three patients. The patients with CVD (Group 1) were significantly male, older, and had higher BMI (p = 0.027, p < 0.001, and p = 0.041). Obesity (33.4%) and hypertension (27.2%) were the two CV risk factors most frequently. Male sex (HR = 7.818, 95% CI 3.030-20.173, p < 0.001) and hypertension (HR = 4.570, 95% CI 1.567-13.328, p = 0.005) were the independent risk factors for CVD. The prevalence of CVD in RA patients was 4.6%. Some common risk factors for CVD in the general population, including male sex, older age, and hypertension, were evident in RA patients. Male sex and hypertension were the independent risk factors for developing CVD in patients with RA.

Cross-sectional analysis of cardiovascular disease and risk factors in patients with spondyloarthritis: a real-life evidence from biostar nationwide registry.

The association between spondyloarthritis and cardiovascular (CV) diseases is complex with variable outcomes. This study aimed to assess the prevalence rates of CV diseases and to analyze the impact of CV risk factors on CV disease in patients with spondyloarthritis. A multi-center cross-sectional study using the BioSTAR (Biological and Targeted Synthetic Disease-Modifying Antirheumatic Drugs Registry) database was performed on patients with spondyloarthritis. Socio-demographic, laboratory, and clinical data were collected. Patients with and without major adverse cardiovascular events (MACE) were grouped as Group 1 and Group 2. The primary outcome was the overall group's prevalence rates of CV disease and CV risk factors. The secondary outcome was the difference in socio-demographic and clinical characteristics between the groups and predictive risk factors for CV disease. There were 1457 patients with a mean age of 45.7 ± 10.9 years. The prevalence rate for CV disease was 3% (n = 44). The distribution of these diseases was coronary artery disease (n = 42), congestive heart failure (n = 4), peripheral vascular disorders (n = 6), and cerebrovascular events (n = 4). Patients in Group 1 were significantly male (p = 0.014) and older than those in Group 2 (p < 0.001). There were significantly more patients with hypertension, diabetes mellitus, chronic renal failure, dyslipidemia, and malignancy in Group 1 than in Group 2 (p < 0.05). Smoking (36.7%), obesity (24.4%), and hypertension (13.8%) were the most prevalent traditional CV risk factors. Hypertension (HR = 3.147, 95% CI 1.461-6.778, p = 0.003), dyslipidemia (HR = 3.476, 95% CI 1.631-7.406, p = 0.001), and cancer history (HR = 5.852, 95% CI 1.189-28.810, p = 0.030) were the independent predictors for CV disease. A multi-center cross-sectional study using the BioSTAR (Biological and Targeted Synthetic Disease-Modifying Antirheumatic Drugs Registry) database was performed on patients with spondyloarthritis. Socio-demographic, laboratory, and clinical data were collected. Patients with and without major adverse cardiovascular events (MACE) were grouped as Group 1 and Group 2. The primary outcome was the overall group's prevalence rates of CV disease and CV risk factors. The secondary outcome was the difference in socio-demographic and clinical characteristics between the groups and predictive risk factors for CV disease. There were 1457 patients with a mean age of 45.7 ± 10.9 years. The prevalence rate for CV disease was 3% (n = 44). The distribution of these diseases was coronary artery disease (n = 42), congestive heart failure (n = 4), peripheral vascular disorders (n = 6), and cerebrovascular events (n = 4). Patients in Group 1 were significantly male (p = 0.014) and older than those in Group 2 (p < 0.001). There were significantly more patients with hypertension, diabetes mellitus, chronic renal failure, dyslipidemia, and malignancy in Group 1 than in Group 2 (p < 0.05). Smoking (36.7%), obesity (24.4%), and hypertension (13.8%) were the most prevalent traditional CV risk factors. Hypertension (HR = 3.147, 95% CI 1.461-6.778, p = 0.003), dyslipidemia (HR = 3.476, 95% CI 1.631-7.406, p = 0.001), and cancer history (HR = 5.852, 95% CI 1.189-28.810, p = 0.030) were the independent predictors for CV disease. The prevalence rate of CV disease was 3.0% in patients with spondyloarthritis. Hypertension, dyslipidemia, and cancer history were the independent CV risk factors for CV disease in patients with spondyloarthritis.

The validity and reliability of the Turkish version of the Arthritis Impact Measurement Scale 2-Short Form (AIMS2-SF) for rheumatoid arthritis.

The objective of this study is to investigate the validity and reliability of the Turkish version of the Arthritis Impact Measurement Scale 2-Short Form (AIMS2-SF). Subjects fulfilling the ACR 2010 classification criteria for RA were enrolled into the study. Scale reliability was investigated using test-retest reliability (intra-class correlation coefficient-ICC) and internal consistency approaches (Cronbach's α). Spearman's rank correlation coefficients evaluated relationships between quantitative parameters and validity. Construct validity was assessed by correlating AIMS2-SF with clinical parameters and functional parameters including, Nottingham Health Profile (NHP), Health Assessment Questionnaire (HAQ), Beck Depression Inventory (BDI) and Duruöz Hand Index (DHI). One hundred and sixteen patients (105 females and 11 males) were recruited. The mean age ± standard deviation (SD) was 52.45 ± 11.48 years. Cronbach's α was 0.88 and the ICC was 0.91. There were significant correlations (rho and p values) with parameters directly related to health-related quality of life (HRQoL); NHP subscales (energy levels: 0.54, pain: 0.62, emotional reaction: 0.50, sleep 0.44, social interaction: 0.51, physical activity: 0.61; p < 0.0005), HAQ (0.60, p < 0.0005), BDI (0.63, p < 0.001) and DHI (0.63, p < 0.0005). Poor or non-significant correlations were found for parameters not directly related to QoL, such as age (0.07, p = 0.45) and disease duration (0.12, p = 0.21); however, disease activity (0.43, p < 0.0005) and NRS pain (0.46, p < 0.0005) were correlated with AIMS2-SF as moderate. The Turkish AIMS2-SF version is a reliable and valid tool that may be used to evaluate QoL for RA. The scale can be easily used in daily practice.

Clinical and functional impact of central sensitization on patients with familial Mediterranean fever: a cross-sectional study.

This study aimed to investigate the frequency of CS and its clinical and functional effects on familial Mediterranean fever (FMF). A hundred FMF patients were included in this study. The presence of CS was investigated by the central sensitization inventory (CSI). In addition to the detailed clinical features of patients and genetic mutations, quality of life, disability, sleep disorders, depression, anxiety, and fibromyalgia frequency were examined to evaluate the negative effects of CS on the individual. Patients were divided into groups according to the presence and severity of CS, and their results were compared. Correlation and multivariate regression analysis were performed to investigate the association of CS  with selected demographic and clinical parameters. The mean CSI was 37.72 (SD: 19.35), and thirty-eight (38%) patients had CS. Sacroiliitis occurred in 11 patients (11%), amyloidosis in 3 (3%), and erysipelas-like erythema in 11 (11%). The most prevalent genetic mutation was M694/any compound heterogeneous (35.7%), followed by M69V homogeneous (30%). Regarding comparing the patients with and without CS, the number of attacks, disease activity, daily colchicine dose, and all investigated comorbidities were significantly higher in the patients with CS (p < 0.05). In regression analysis, gender, colchicine dose and sleep disturbance were detected as related parameters with CS (OR (95% CI): 6.05 (1.39; 26.32), p: 0.017, OR (95% CI): 6.69 (1.65; 27.18), p: 0.008, OR (95% CI): 1.35 (1.35; 1.59), p: 0.001, respectively). Concomitant pain sensitization appears to be related to FMF patients' clinical and functional characteristics. These results suggest taking into consideration CS in the management of FMF patients.

Familial Mediterranean fever: perspective on female fertility and disease course in pregnancy from a multicenter nationwide network.

The aim of this study was to analyze the pregnancy process, especially the Familial Mediterranean fever (FMF) disease course and attack types during pregnancy, and to examine the relationship between disease-related factors and female infertility in FMF patients. The study, which was planned in a multicenter national network, included 643 female patients. 435 female patients who had regular sexual intercourse were questioned in terms of infertility. Pregnancy and delivery history, FMF disease severity and course during pregnancy were evaluated. The relationship between demographic and clinical findings, disease severity, genetic analysis results and infertility was investigated. 401 patients had at least 1 pregnancy and 34 patients were diagnosed with infertility. 154 patients had an attack during pregnancy. 61.6% of them reported that attacks during pregnancy were similar to those when they were not pregnant. The most common attack symptoms were fever, fatigue and abdominal pain-peritonitis (96%, 87%, and 83%, respectively) in the pregnancy period. The disease-onset age, disease activity score, gene mutation analyses, and regular colchicine use (> 90%) were similar between the fertile and infertile groups, while the frequency of previous appendectomy and alcohol consumption rates were higher in individuals with infertility. Our results indicated no significant change in the frequency and severity of attacks during pregnancy. The low rate of infertility (7.8%) in our patients was noted. It has been suggested that the risk of FMF-related infertility may not be as high as thought in patients who are followed up regularly and received colchicine.

Beyond expectations: disease duration and psychological burden in psoriatic arthritis.

This study aims to investigate the relationship between disease duration and psychological burden in PsA and to identify the risk factors associated with psychological distress. Patients with PsA who met CASPAR classification criteria enrolled by Turkish League Against Rheumatism (TLAR)-Network. Patients were categorized into three groups based on disease duration: early stage (< 5 years), middle stage (≥ 5, < 10 years), and late stage (≥ 10 years). All patients underwent clinical and laboratory assessment using standardized protocol and case report forms. The associations between psychological variables and clinical parameters were assessed by a multivariate analysis. Of the 1113 patients with PsA (63.9% female), 564 (%50.7) had high risk for depression and 263 (%23.6) for anxiety. The risk of psychological burden was similar across all PsA groups, and patients with a higher risk of depression and anxiety also experienced greater disease activity, poorer quality of life, and physical disability. Multivariate logistic regression revealed that female gender (OR = 1.52), PsAQoL (OR = 1.13), HAQ (OR = 1.99), FiRST score (OR = 1.14), unemployment/retired (OR = 1.48) and PASI head score (OR = 1.41) were factors that influenced the risk of depression, whereas the current or past enthesitis (OR = 1.45), PsAQoL (OR = 1.19), and FiRST score (OR = 1.26) were factors that influenced the risk of anxiety. PsA patients can experience a comparable level of psychological burden throughout the course of their disease. Several socio-demographic and disease-related factors may contribute to mental disorders in PsA. In the present era of personalized treatment for PsA, evaluating psychiatric distress can guide tailored interventions that improve overall well-being and reduce disease burden.

Evaluation of hepatitis serology and frequency of viral reactivation in patients with inflammatory arthritis receiving biologic agents: a multicenter observational study.

To evaluate of hepatitis serology and reactivation frequency in patients with rheumatic disease receiving biologic agents. Our study included patients with inflammatory rheumatic diseases from 23 centers, who were followed up with biological therapy. Demographic and clinical characteristics of the patients, duration of drug use and hepatitis serology and the state of viral reactivation were analyzed. A total of 4060 patients, 2095 being males, were included in our study. Of the patients, 2463 had Ankylosing Spondylitis (AS), 1154 had Rheumatoid Arthritis (RA), 325 had Psoriatic Arthritis (PsA), and 118 had other inflammatory rheumatic diseases. When the viral serology of the patients was evaluated, 79 patients (2%) who were identified as HBs Ag positive, 486 (12%) patients who were HBs Ag negative and anti-HBc IgG positive and 20 patients (0.5%) who were anti-HCV positive. When evaluated on a disease-by-disease basis, the rate of HBsAg was found to be 2.5% in RA, 2% in AS and 0.9% in PsA. Viral reactivation was detected in 13 patients while receiving biologic agents. HBs Ag was positive in nine patients with reactivation and negative in four patients. Anti-HBc IgG, however, was positive. Six of these patients had AS, four had RA, and three had PsA. The development of hepatitis reactivation in 11.4% of HBs Ag positive patients and 0.82% of anti-HBc IgG positive patients due to the use of biologic agents is an important problem for this group of patients. Antiviral prophylaxis is recommended to be started especially in patients who are HBs Ag positive and who are using biologic agents due to viral reactivation. Therefore, it is important to carry out hepatitis screenings before biologic agent treatment and to carefully evaluate the vaccination and prophylaxis requirements.

Diagnostic delay in psoriatic arthritis: insights from a nationwide multicenter study.

This study aimed to investigate the duration of diagnostic delay in patients with psoriatic arthritis (PsA) and identify potential contributing factors using a comprehensive, population-based approach. Data were obtained from the Turkish League Against Rheumatism (TLAR)-Network, involving patients who met the CASPAR criteria. Diagnostic delay was defined as time interval from symptom onset to PsA diagnosis, categorized as ≤ 2 years and > 2 years. Temporal trends were assessed by grouping patients based on the year of diagnosis. Various factors including demographics, clinical characteristics, disease activity, quality of life, physical function, disability, fatigue, and well-being were examined. Logistic regression models were used to identify factors associated with diagnostic delay. Among 1,134 PsA patients, mean diagnostic delay was 35.1 months (median: 12). Approximately 39.15% were diagnosed within 3 months, and 67.02% were diagnosed within 24 months. Patients experiencing longer delays had higher scores in Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), patient's global assessment (PtGA) and physician's global assessment (PhGA). Diagnostic delay has decreased over time, with median delay falling from 60 to 24 months throughout pre-2010 and 2015-2019 terms. Several factors were identified as significant contributors to delayed diagnosis, including lower levels of education (OR = 2.63), arthritis symptoms preceding skin manifestations (OR = 1.72), low back pain at first visit (OR = 1.60), symptom onset age (OR = 0.96), and psoriasis subtype (OR = 0.25). Timely diagnosis of PsA is crucial for effective management and improved outcomes. Despite recent improvements, about one-third of PsA patients still experience delays exceeding 2 years. By identifying influential factors such as education level, arthritis symptoms preceding skin manifestations, initial visit symptoms, age of symptom onset, and psoriasis subtype, healthcare practitioners may create specific techniques to help in early detection and intervention.

Associations of Polypharmacy With Clinical Parameters, Function, and Health-Related Quality of Life in Psoriatic Arthritis.

OBJECTIVE: The aim of this study was to assess predictors of polypharmacy and its effect on health-related quality of life in patients with psoriatic arthritis (PsA). METHODS: This cross-sectional study was performed between February and December 2019. The number of medications was grouped into minor (2-4) and major (≥5) polypharmacy. Functional status and quality of life were assessed using the Health Assessment Questionnaire and Short-Form 36, respectively. Clinical and demographic characteristics, physical function, and quality of life of the polypharmacy group were compared. Predictive factors for major polypharmacy were evaluated using a logistic regression analysis. RESULTS: The mean age of the 100 patients (70 females and 30 males) with PsA was 48.43 ± 12.94 years. The proportion of patients with major polypharmacy was 19%. The physical function subscale of Short-Form 36 was lower in the major polypharmacy group ( p = 0.009). Univariable analysis revealed that sex, body mass index, disease duration, disease activity, psoriasis severity, dactylitis, enthesitis, PsA subtypes, smoking, and Health Assessment Questionnaire were not associated with major polypharmacy ( p > 0.10). In the multivariable model, the number of comorbidities (odds ratio, 3.151; 95% confidence interval, 1.828-5.429; p < 0.001) and age ≥60 years (odds ratio, 4.864; 95% confidence interval, 1.159-20.418; p = 0.031) were significantly associated with major polypharmacy. CONCLUSIONS: The number of comorbid diseases and age ≥60 years were the factors associated with major polypharmacy in patients with PsA. Although physical function was not associated with polypharmacy, patients with major polypharmacy had poorer quality of life.

Seasonal residual activity in adult familial Mediterranean fever: a longitudinal observational study.

Although it is assumed that cold exposure triggers inflammation in patients with familial Mediterranean fever (FMF), seasonal differences in FMF have not yet been investigated. This study aims to investigate the association of seasonal changes with the frequency of attacks, disease severity, and subclinical inflammation in FMF. This longitudinal study examined adult patients with FMF on an established treatment followed up for at least 1 year in Istanbul. Clinical characteristics, medications, intraseasonal attacks counts, arthralgia and arthritis, disease severity, and the subclinical inflammation parameters were recorded covering four seasons. Friedman's and Cochran's Q tests were used to analyze changes in the above-mentioned data over seasons. Additionally, all attacks experienced in each season were added, and interseasonal differences were compared with the Chi-square goodness-of-fit test. Data for 240 observations (60 patients) were analyzed. The mean age and disease duration were 39.78 (SD 11.91) and 10 (IQR 6-22.75) years, respectively. The comparison of medians for four seasons did not show any statistical differences in terms of attack frequency, disease severity parameters, markers of subclinical inflammation, and the presence of arthralgia and arthritis. The total number of intraseasonal attacks experienced by patients differed among the seasons (p = 0.023), with a higher count in winter. Adult individuals with established FMF are more likely to experience attacks in winter than summer, but this difference may not be seen in the general parameters of disease activity/severity. This result supports the notion that there is a pronounced residual activity in winter.

Spondyloarthritis in familial Mediterranean fever: a cohort study.

Familial Mediterranean fever (FMF) and spondyloarthritis (SpA) may show several common signs. This study aimed to evaluate the frequency of SpA and its manifestations in FMF, the impact of SpA on FMF, and the associations of non-episodic findings (heel enthesitis, protracted arthritis, and sacroiliitis) with the FMF features. Demographic, clinical, imaging, and genetic data were retrieved from medical records of the patients with adult FMF. To identify patients who met the classification criteria for SpA, data including rheumatologic inquiry were recorded. Patients with SpA and those who did not meet the criteria were compared in terms of FMF features. Regression analyses were performed to determine the factors that were most associated with sacroiliitis, enthesitis, and protracted arthritis. Of the 283 patients with FMF, 74 (26.1%) met the SpA criteria (64 axial, 10 peripheral); and 65 (22.9%) patients had sacroiliitis, 27 (9.5%) protracted arthritis, and 61 (21.6%) heel enthesitis. Patients with SpA were older and had more FMF severity, and heel pain rate than those without; however, genetic features, CRP, resistance to colchicine, and heel enthesitis did not differ. A meaningful number of patients without SpA had also displayed heel enthesitis, protracted arthritis, inflammatory back pain, heel pain, family history of SpA, and elevated CRP. Age was found to be the main predictor of heel enthesitis and protracted arthritis was linked with FMF severity. A significant number of patients with FMF meet the peripheral SpA classification criteria as well as axial SpA. SpA and its shared manifestations with FMF may have an impact on FMF.

Canakinumab is effective in patients with familial Mediterranean fever resistant and intolerant to the colchicine and/or anakinra treatment.

As an autosomal recessive autoinflammatory disease, treatment of Familial Mediterranean fever (FMF) has still gaps. Clinical studies are proving the safety and efficacy of colchicine in patients with FMF. However, there are very limited data on colchicine-resistant patients treated with canakinumab. This study presents the real-life experience of two rheumatology clinics choosing canakinumab in adult patients with FMF resistant to standard therapy. Treatment-resistant FMF patients with validated diagnoses enrolled from two rheumatology clinics. A special database was generated for the study and patients' demographic characteristics, FMF attack characteristics, adverse events seen during treatment, family history, MediterraneanFeVer (MEFV) mutations, and laboratory results recorded. Patients with missing dates were excluded from the analysis. PRAS score is used to assess the disease activity. A total of thirty colchicine and/or anakinra-resistant patients were enrolled to study. Twenty-one patients were female (70%) and the average disease duration was 21 years. The time from colchicine to anakinra was 4.27 years and the time to canakinumab was 1.52 years. Abdominal pain (100%), fever (93.3%), chest pain (56.7%) were the most prevailed findings. Morning stiffness, myalgia, low back pain, chest pain was the predominant musculoskeletal findings. Median colchicine dose was 2 mg/day (min-max 0.5-3 mg/day). The most common side effect during anakinra treatment, apart from treatment unresponsiveness, was injection site reactions. Before canakinumab treatment, the mean number of attacks was 8.3 in the 24 weeks, 4.33 in the third month of canakinumab treatment, and 1.56 at the last visit (p < 0.001). Also, the mean duration of attacks was 67.20 h before canakinumab treatment, this period decreased to 18.27 h after six months of canakinumab treatment (p < 0.001). Canakinumab is effective and tolerable to reduce attacks in resistant patients with FMF. Laboratory findings and clinical observation reveals that canakinumab can be another treatment option for colchicine and/or anakinra non-responders. Further studies with larger patients are required to validate recent findings with canakinumab.

Validity and psychometric characteristics of the self-administered comorbidity questionnaire in patients with psoriatic arthritis.

The study aimed to translate and cross-culturally adapt the self-comorbidity questionnaire (SCQ) into Turkish and investigate the validity and reliability of SCQ and its modified version (mSCQ) in psoriatic arthritis (PsA). Psoriatic arthritis quality of life (PsAQoL) and short form 36 (SF-36) were used to assess the quality of life. The physical disability was evaluated with the health assessment questionnaire (HAQ). The reliability of the SCQ scale was assessed by test-retest reliability. For construct validity, the correlations of SCQ with the HAQ, SF-36, PsAQoL, age, body mass index (BMI), disease duration, disease activity in psa (DAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Psoriasis Area and Severity Index (PASI), dactylitis and enthesitis were evaluated. The mSCQ was also used by removing the items related to rheumatic conditions. For the test-retest reliability of the Turkish version of SCQ, the intraclass correlation coefficient was 0.965, p < 0.001. The SCQ and mSCQ had significant correlations with HAQ, PsAQoL, some subscales of SF-36, and age (p < 0.05), but not with disease duration, BASDAI, PASI and dactylitis (p > 0.05). Although SCQ had a low correlation with DAPSA (rho = 0.262, p = 0.031), mSCQ was not correlated with DAPSA (p > 0.05). mSCQ was significantly correlated with BMI (rho = 0.233, p = 0.016), but SCQ was not (p > 0.05). The Turkish version of SCQ had adequate reliability and validity, and the mSCQ improved the validity of the scale in patients with PsA.

Assessment of autonomic dysfunction with the COMPASS-31 and its relationship with disease activity and cardiovascular risks in patients with psoriatic arthritis.

This study aimed to evaluate the autonomic dysfunction as assessed by the Composite Autonomic Symptom Score-31 (COMPASS-31) as well as its relationship with disease activity and cardiovascular risks in patients with psoriatic arthritis (PsA). This cross-sectional observational study involved 118 PsA patients (85 females, mean age 45.6 years) and 64 healthy subjects. Cardiovascular risks were recorded including body mass index (BMI), hypertension (HT), diabetes mellitus (DM), dyslipidemia, metabolic syndrome (MetS), and 10-year Framingham Risk scores (FRS) were calculated. PsA was assessed with regard to disease activity, quality of life, and function. Autonomic dysfunction was evaluated using the COMPASS-31 consisting of six subdivisions including orthostatic, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor functions. The mean disease duration was 63.3 months. The mean total COMPASS-31 score was significantly higher in PsA patients than in controls (24.4 vs 11.1; p < 0.001), as were all sub-domain scores. COMPASS-31 scores were significantly lower in patients with DAPSA-REM and MDA. The COMPASS-31 total score showed significant correlations with scores of pain, global assessment, fatigue, function, quality of life, DAPSA, and BASDAI (p < 0.05).The presence of HT, dyslipidemia, MetS, and abdominal obesity did not significantly affect the total COMPASS-31 and sub-domain scores, except for the secretomotor scores being significantly higher in patients with abdominal obesity and MetS (p < 0.05). COMPASS-31 scores were not significantly different across the FRS risk groups. The symptoms of autonomic dysfunction are prevalent in PsA patients. High disease activity and pain have negative effects on autonomic function, and also functional impairment, fatigue, and poor quality of life are associated with autonomic dysfunction. However, the COMPASS-31 was found to be insufficient to demonstrate a clear relationship between autonomic dysfunction and cardiovascular risk.

Perspective of sarcoidosis in terms of rheumatology: a single-center rheumatology clinic experience.

Sarcoidosis may present with many rheumatological symptoms as well as mimic and/or may occur concomitantly with many other rheumatic diseases. We examined the demographic, clinical and laboratory characteristics of patients diagnosed with sarcoidosis in the rheumatology department. This study planned as retrospective cross-sectional study. Medical records of patients who applied to our rheumatology outpatient clinic due to complain of musculoskeletal problems and then diagnosed sarcoidosis were retrospectively investigated. Joint findings, extrapulmonary involvements, and coexisting rheumatic disease were evaluated. Fifty-six patients (41.21 ± 7.83 years, 75% female) were included. The duration of the disease was 49.61 ± 29.11 months, and the follow-up period was 26.66 ± 13.26 months. All patients had pulmonary system involvement. Arthralgia was present in 91.10% of 56 patients and arthritis in 89.29% of patients. Examining the subtypes of the arthritis findings, mono-arthritis was found in 31/50 (62%) patients, oligo-arthritis in 15/50 (30%) patients, and polyarthritis in 4/50 (8%) patients. A total of 11 (19.60%) patients were diagnosed with uveitis. Excision of the mediastinal LAP was performed in a total of 37 patients (66.1%) and became the most commonly employed method. Considering the treatment distribution of the patients under followed-up, it is seen that non-steroidal anti-inflammatory treatments were used in 15 (26.8%) patients, corticosteroids in a total of 40 (71.4%) patients, methotrexate in a total of 15 patients (26.8%), azathioprine in six (10.7%) patients, hydroxychloroquine in 14 (25%) patients, and infliximab in one (1.8%) patient. As sarcoidosis is a mimicking disease, a good differential diagnosis should be made to avoid misdiagnosis and in order not to be late in diagnosis and treatment. Physicians, especially rheumatologists, should remember sarcoidosis more frequently as the disease may overlap with other rheumatological diseases and may occur with many rheumatological manifestations.

Real-life data on tapering or discontinuation of canakinumab therapy in patients with familial Mediterranean fever.

This study aimed to investigate the disease characteristics of familial Mediterranean fever (FMF) patients undergoing dose optimisation and discontinuation of canakinumab therapy. A total of 61 patients diagnosed with FMF and using canakinumab for the resistant disease were enrolled on this retrospective study. Patients' characteristics, disease activity, treatment response, dose optimisation, dose intervals, attack-free periods, drug-free periods and side effects were noted. Dose intervals were extended in patients who achieved remission without being bound by any protocol at the discretion of the rheumatology physician who followed up with the patients in the outpatient clinic. The drug was discontinued in some patients whose dose intervals were 2 months or longer and remained in remission for 6 months or longer. A total of 57 patients (56% female, median age 32.4 years) were included. The mean attack frequency before canakinumab was 3.4/6 months, while it was 1.2 at the last post-treatment visit (p < 0.001). The median duration of canakinumab use was 46 months. After the first 6 months, the dosing interval was extended in 22 patients, and then treatment was discontinued in 12 of them who did not have an attack in the last 6 months. Three of the 12 patients whose treatment was discontinued started monthly treatment again after their attacks recurred. In the remaining ten patients, dose intervals were extended to 8-12 weeks after 6 months of monthly treatment. Nine patients are still being followed up without attacks and receive only colchicine therapy. Canakinumab is a safe and effective treatment, dose intervals may be extended, and follow-up without medication may be possible for eligible patients. However, there is a need for a consensus on dose optimisation or tapering.

Impact of obesity on quality of life, psychological status, and disease activity in psoriatic arthritis: a multi­center study.

This article aims to evaluate the possible effect of obesity on quality of life, psychological status, and other clinical variables in Psoriatic arthritis (PsA). PsA patients have been recruited by the Turkish League Against Rheumatism-Network from various centers in Turkey in this cross-sectional study. Patients with a body mass index (BMI) ≥ of 30 kg/m2 were considered obese. Differences among patients with regard to obesity status were assessed with health-related quality of life measures (PsA Quality of Life Questionnaire [PsAQoL]), psychological status (Hospital Anxiety and Depression Scale [HADS]), and disease activity parameters (the Disease Activity index for PSoriatic Arthritis [DAPSA], Disease Activity Score 28-C-reactive protein [DAS28-CRP], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI], Psoriasis Area and Severity Index [PASI]), physical functions (Ankylosing Spondylitis Functional Index [BASFI], Health Assessment Questionnaire [HAQ], and Health Assessment Questionnaire for the spondyloarthropathies [HAQ-S]). Pain was assessed using visual analog scale of pain (VAS-P), and fatigue was evaluated using visual analog scale of fatigue (VAS-F) and Functional Assessment of Chronic Illness Therapy (FACIT). A total of 1033 patients with PsA, 650 (62.9%) non-obese and 383 (37.1%) obese were included in the study. The PsAQoL, HADS-Anxiety, HADS-Depression, DAPSA, DAS28-CRP, BASDAI, BASFI, HAQ and HAQ-S scores of the obese group were higher than the non-obese group (p < 0.05). VAS-P and PASI scores were similar between group of patients with and without obesity. Obese patients had higher median scores of VAS-F and FACIT than non-obese patients (p < 0.05). Linear regression analysis showed that BMI affects the quality of life, depression, and disease activity. Consequently, obesity has significant associations with higher disease activity, lower QoL, risk of anxiety, depression, and fatigue. Therefore, obesity should also be taken into account in the management of PsA patients.

Central sensitization in axial spondyloarthritis: An explorative study with quantitative sensory testing and clinical scales.

OBJECTIVES: To evaluate the central sensitization (CS) and the related parameters in patients with axial spondyloarthritis (axSpA). METHODS: Quantitative sensory testing (QST) which consists of pressure pain threshold (PPT), temporal summation (TS), and conditioned pain modulation (CPM) were applied to the participants. Disease activity, functional status, sleep quality, pain, depression, and fatigue were assessed. Patients were divided as the ones with and without CS according to the central sensitization inventory (CSI) and the results were compared. RESULTS: One hundred patients and 50 controls were recruited. Sixty axSpA patients had CS. When QST results were compared between the patient and control groups, all PPT scores were found lower (p < 0.05) in patients. Regarding the comparison of the patients with and without CS, sacroiliac, and trapezius PPT scores were found lower in the patients with CS (p < 0.05). There was no significant difference between groups in TS values (p > 0.05). All investigated comorbidities were found to be significantly more frequent (p < 0.001) in the patients with CS. CONCLUSIONS: CS and related comorbidities were found to be increased in axSpA patients. This increase should be taken into consideration in the management of these patients.

PsART-ID inception cohort: clinical characteristics, treatment choices and outcomes of patients with psoriatic arthritis.

OBJECTIVES: Our aim is to understand clinical characteristics, real-life treatment strategies, outcomes of early PsA patients and determine the differences between the inception and established PsA cohorts. METHODS: PsArt-ID (Psoriatic Arthritis- International Database) is a multicentre registry. From that registry, patients with a diagnosis of PsA up to 6 months were classified as the inception cohort (n==388). Two periods were identified for the established cohort: Patients with PsA diagnosis within 5-10 years (n = 328), ≥10 years (n = 326). Demographic, clinical characteristics, treatment strategies, outcomes were determined for the inception cohort and compared with the established cohorts. RESULTS: The mean (s.d.) age of the inception cohort was 44.7 (13.3) and 167/388 (43.0%) of the patients were male. Polyarticular and mono-oligoarticular presentations were comparable in the inception and established cohorts. Axial involvement rate was higher in the cohort of patients with PsA ≥10 years compared with the inception cohort (34.8% vs 27.7%). As well as dactylitis and nail involvement (P = 0.004, P = 0.001 respectively). Both enthesitis, deformity rates were lower in the inception cohort. Overall, 13% of patients in the inception group had a deformity. MTX was the most commonly prescribed treatment for all cohorts with 10.7% of the early PsA patients were given anti-TNF agents after 16 months. CONCLUSION: The real-life experience in PsA patients showed no significant differences in the disease pattern rates except for the axial involvement. The dactylitis, nail involvement rates had increased significantly after 10 years from the diagnosis and the enthesitis, deformity had an increasing trend over time.
