Öğe Clinical characteristics, disease activity, functional status, and quality of life results of patients with psoriatic arthritis using biological and conventional synthetic disease-modifying antirheumatic drugs(Turkish League Against Rheumatism, 2021) Keskin, Yasar; Nas, Kemal; Kilic, Erkan; Sargin, Betul; Kasman, Sevtap Acer; Alkan, Hakan; Sahin, NilayObjectives: This study aims to compare the clinical characteristics, disease activity, and quality of life (QoL) of patients with psoriatic arthritis (PsA) who use biological and conventional synthetic disease-modifying antirheumatic drugs (DMARDs) in a nationwide cohort throughout Turkey. Patients and methods: A total of 961 patients (346 males, 615 females; mean age: 46.9+/-12.2 years; range, 18 to 81 years) with PsA according to the classification criteria for PsA were included in the study. The patients demographic and clinical characteristics, physical examination results, Disease Activity Score 28, Disease Activity Index for Psoriatic Arthritis and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Psoriasis Area and Severity Index, Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Metrology Index, Hospital Anxiety and Depression Scale, Health Assessment Questionnaire, Psoriatic Arthritis Quality of Life (PsAQoL), and Short Form-36 scores were all recorded. Results: Of the patients, 23% underwent biological DMARD (bDMARD) monotherapy, 42% underwent conventional synthetic DMARD (csDMARD) monotherapy, 10% underwent a csDMARD combination therapy, and 10% underwent a combination bDMARD and csDMARD treatment. The Visual Analog Scale (VAS pain), patient global assessment, physician global assessment, and BASDAI scores were found to be lower among patients using combination treatment of csDMARD and bDMARD, while the swollen joint count was found to be lower among patients using bDMARD. The PsAQoL score was found to be the lowest among patients not using any medication and the highest among those using bDMARD. Conclusion: In our study, patients with PsA were successfully treated with both csDMARD and bDMARD monotherapy. When the biological treatments used for PsA were compared with csDMARD, it was found that biological treatments had a positive effect on both disease activity and the QoL. Combinations of csDMARDs and bDMARDs were preferred in cases in which the disease activity was still high or increased. Because of the highest efficacy of the combined treatment, we highly suggest increasing the number of patients on combined treatment.Öğe The effect of gender on disease activity and clinical characteristics in patients with axial psoriatic arthritis(Taylor & Francis Ltd, 2021) Nas, Kemal; Kilic, Erkan; Tekeoglu, Ibrahim; Keskin, Yasar; cevik, Remzi; Sargin, Betul; Acer Kasman, SevtapObjectives In this study, we aimed to evaluate the effect of gender on clinical findings, disease activity, functional status and quality of life in patients with axial involvement in Turkey. Methods Patients with PsA who met the CASPAR classification criteria were enrolled consequently in this cohort. Turkish League Against Rheumatism (TLAR)-Network was formed with the participation of 25 centres. The demographic variables, fatigue, diagnostic delay, the beginning of peripheral arthritis, enthesitis, dactylitis and spine involvement, inflammatory low back pain, BASFI, HAQ, HAQ-s, visual analogue scale-pain (VAS-pain), anxiety, depression and disease activity parameters (ESR, DAS28, BASDAI) were recorded. Axial involvement was assessed according to clinical and radiological data according to modified New York (MNYC) or Assessment of SpondyloArthritis international Society (ASAS) criteria. Results A total of 1018 patients with PsA were included in this study. Of the 373 patients with axial involvement, 150 were male (40.2%) and 223 (59.8%) were female. Spondylitis was detected in 14,7% of men and 21,9% of women in all patients. Pain score (VAS) (p < .002), fatigue (p < .001), ESR (p < .001), DAS28 (p < .001), BASDAI score (p < .001), PsAQoL (p < .001), HAQ score (p < ,01), HAQ-S score (p < .001), anxiety (p < .001), depression (p < .024), FACIT (p < .001) and FiRST (p < .001) scores were statistically significantly worse in women than males with axial PsA. However, quality of life was better (p < .001) and PASI score (p < .005) were statistically worse in male patients than in female patients with axial involvement. Conclusion This study has shown that the burden of disease in axial PsA has significant difference between genders. Disease activity, physical disability, functional limitation, depression and anxiety scores were higher in female patients, while quality of life were better and PASI score were higher in male patients. Therefore, we suggest that new strategies should be developed for more effective treatment of axial PsA in female patients.Öğe THE EFFECT OF GENDER ON DISEASE ACTIVITY, FUNCTIONAL INDEX AND QUALITY OF LIFE IN PATIENTS WITH AXIAL SPA. THE DATA OF TLAR-NETWORK PSA STUDY(Bmj Publishing Group, 2019) Nas, Kemal; Kilic, Erkan; Tekeoglu, Ibrahim; Cevik, Remzi; Sargin, Betul; Kasman, Sevtap Acer; Alkan, Hakan[Abstract Not Availabe]Öğe Enthesitis and its relationship with disease activity, functional status, and quality of life in psoriatic arthritis: a multi-center study(Springer Heidelberg, 2020) Sunar, Ismihan; Ataman, Sebnem; Nas, Kemal; Kilic, Erkan; Sargin, Betul; Kasman, Sevtap Acer; Alkan, HakanPsoriatic arthritis (PsA) is an inflammatory arthritis with distinct phenotypic subtypes. Enthesitis is assigned as a hallmark of the disease, given its significant relations to disease activity and quality of life. Our objective is to evaluate the prevalence of enthesitis and its association with some clinical parameters, particularly quality of life, using data from a national registry. Patients with PsA meeting ClASsification criteria for Psoriatic Arthritis (CASPAR) were enrolled by means of a multi-centre Turkish League Against Rheumatism (TLAR) Network Project. The following information was recorded in web-based case report forms: demographic, clinical and radiographic data; physical examination findings, including tender and swollen joint counts (TJC and SJC); nail and skin involvement; Disease Activity Score-28 for Rheumatoid Arthritis with Erythrocyte Sedimentation Rate (DAS 28-ESR); Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); Maastricht Ankylosing Spondylitis Enthesitis Score (MASES); Psoriasis Area Severity Index (PASI); Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI-s); Health Assessment Questionnaire (HAQ); Bath Ankylosing Spondylitis Functional Index (BASFI); Health Assessment Questionnaire for the spondyloarthropathies (HAQ-s); Psoriatic arthritis quality of Life scale (PsAQoL); Short Form 36 (SF-36); Hospital Anxiety Depression Scale (HADS); Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); and Fibromyalgia Rapid Screening Tool (FiRST) scores. The patients were divided into two groups, namely with and without enthesitis, based on the triple Likert-type physician-reported statement of 'active enthesitis', 'history of enthesitis' or 'none' in the case report forms. Patients with active enthesitis were compared to others in terms of these clinical parameters. A total of 1130 patients were enrolled in this observational study. Of these patients, 251 (22.2%) had active enthesitis according to the clinical assessment. TJC, HAQ-s, BASDAI, FiRST and PsAQoL were significantly higher whereas the SF-36 scores were lower in patients with enthesitis (p < 0.05). Chronic back pain, dactylitis, and tenosynovitis were more frequent in the enthesopathy group (59.4%/39%, 13.1%/6.5% and 24.7%/3.4%, respectively). Significant positive correlations between the MASES score and the TJC, HAQ, DAS 28-ESR, BASDAI, FiRST and PsAQoL scores, and a negative correlation with the SF-36 score were found. When linear regression analysis was performed, the SF-36 MCS and PCS scores decreased by - 9.740 and - 11.795 units, and the FiRST scores increased by 1.223 units in patients with enthesitis. Enthesitis is an important involvement of PsA with significant relations to quality of life determined with PsAQoL and SF-36 scores. Our study found higher frequency of dactylitis and chronic back pain, and worse quality of life determined with SF-36 and PsAQoL scores in patients with enthesitis.Öğe Familial mediterranean fever: assessment of clinical manifestations, pregnancy, genetic mutational analyses, and disease severity in a national cohort(Springer Heidelberg, 2020) Bodur, Hatice; Yurdakul, Fatma Gul; Cay, Hasan Fatih; Ucar, Ulku; Keskin, Yasar; Sargin, Betul; Gurer, GulcanThe aims of this study were to investigate the main clinical and laboratory features, including pregnancy and genetic analysis, of Turkish Familial Mediterranean Fever (FMF) patients and to analyze the relationships between genotypic features, age of disease onset, clinical findings, and disease severity. A study was planned within a national network of 22 different centers. Demographics, clinical and laboratory findings, attack characteristics, drugs, pregnancy and birth history, disease severity, and gene mutation analyses were evaluated. Disease severity, assessed using a scoring system developed by Pras et al., was evaluated in relation to gene mutations and age of disease onset. A total of 979 patients (643 females and 336 males; mean age: 35.92 +/- 11.97 years) with FMF were included in the study. Of a total of 585 pregnancies, 7% of them resulted in preterm birth and 18.1% resulted in abortions. During pregnancy, there was no FMF attack in 61.4% of patients. Of the MEditerranean FeVer (MEFV) mutations, 150 (24.3%) cases were homozygous, 292 (47.3%) cases were heterozygous, and 175 (28.4%) were compound heterozygous. Patients with homozygous gene mutations had more severe disease activity, earlier age of disease onset, higher rates of joint and skin involvement, sacroiliitis, and amyloidosis. Patients with compound heterozygous genotype displayed severe disease activity in close resemblance to patients with homozygous mutation. In addition, patients with compound heterozygous mutations had higher rates of protracted febrile myalgia and elevated fibrinogen levels. In 63.9% of compound heterozygous patients, age of onset was < 20 years, with greater disease severity, and high rates of attack frequency and colchicine resistance. Our results suggest that indicators for disease severity include early onset of disease and homozygous gene mutations. Furthermore, patients with compound heterozygous mutations displayed significant presentations of severe disease activity.Öğe Familial Mediterranean fever: Health-related quality of life and associated variables in a national cohort(Turkish League Against Rheumatism, 2021) Bodur, Hatice; Yurdakul, Fatma Gul; Duruoz, Mehmet Tuncay; Cay, Hasan Fatih; Ucar, Ulku; Keskin, Yasar; Sargin, BetulObjectives: This study aims to evaluate the effectivity of Familial Mediterranean Fever Quality of Life (FMF-QoL) Scale for the measurement of QoL in patients with FMF and to perform correlations between related clinical variables in Turkish patients. Patients and methods: This multicenter prospective study performed between December 2017 and November 2018 included 974 FMF patients (334 males, 640 females; median age: 35; range, 26 to 45 years). Sociodemographic characteristics and clinical features were recorded. All participants were asked to complete the FMF-QoL Scale, Short Form-36 (SF-36), Hospital Anxiety and Depression Scale (HADS), Health Assessment Questionnaire (HAQ), and Functional Assessment of Chronic Illness Therapy (FACIT) Scale. Results: The median FMF-QoL Scale score was 26. Higher FMF-QoL Scale scores were shown to be related to female sex, illiteracy or primary education, monthly low-income (US$<300), smoking, late-onset FMF (>20 years), a higher number of attacks per month (>1/month), and severe disease. FMF-QoL Scale scores were correlated negatively with subscales of SF-36, and positively with HADS-anxiety and HADS-depression scores, HAQ and FACIT. Conclusion: Female sex, smoking, lower educational status, more severe disease, fatigue, and functional impairment were associated with poor QoL. FMF-QoL Scale was noted as a valid and simple patient-reported outcome instrument and correlated with the SF-36 scale.Öğe A Gender-based Analysis of Disease Activity and Its Relationship with Anxiety, Depression, Fatigue, and Fibromyalgia in Psoriatic Arthritis(Wiley, 2019) Duruoz, Mehmet Tuncay; Gezer, Halise Hande; Nas, Kemal; Kilic, Erkan; Sargin, Betul; Kasman, Sevtap Acer; Alkan, Hakan[Abstract Not Availabe]Öğe Gender-related differences in disease activity and clinical features in patients with peripheral psoriatic arthritis: A multi-center study(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021) Duruoz, Mehmet Tuncay; Gezer, Halise Hande; Nas, Kemal; Kilic, Erkan; Sargin, Betul; Kasman, Sevtap Acer; Alkan, HakanObjective: This study sought to compare disease activity, clinical features, and patient-reported outcomes concerning anxiety, depression, fatigue, function, quality of life, and fibromyalgia between female and male patients with peripheral PsA in a Turkish population. Methods: This multi-center Turkish League Against Rheumatism (TLAR) Network study included 1038 patients (678 females, 360 males) diagnosed with peripheral PsA according to the CASPAR criteria. The demographic and clinic parameters of the patients were recorded. Disease activity was evaluated using the scores of DAS28 and cDAPSA. Remission, minimal disease activity (MDA), and very low disease activity (VLDA) were determined. Health Assessment Questionnaire (HAQ), Short-Form-36 (SF-36), Hospital Anxiety and Depression Scale (HAD), fatigue VAS (0-10), and Fibromyalgia Rapid ScreeningTool (FiRST) were used. Disease activity and patient-reported outcomes were compared in male and female patients, and the predictors of MDA for both genders were analyzed. Results: The patients' mean age was 47.6 years (SD: 12) for females and 46.3 years (SD: 12.3) for males. In terms of DAS28 and cDAPSA, female patients had significantly higher disease activity scores, while male patients had significantly higher remission rates (P<0.05). There was a significant difference in the rate of MDA in favor of males (P<0.05), but not in VLDA. The incidences of dactylitis, enthesitis, tenosynovitis, and inflammatory bowel disease were similar in male and female patients, except for spondylitis, which was higher in males (P<0.05). Overall, although there was no significant between-group difference in age and disease duration, female patients had significantly higher BMI and late-onset disease (P<0.05). Female patients had higher HAD, HAQ, and FiRST and lower SF-36 scores than males (P<0.05). In both male and female patients, the disease activity score of cDAPSA was significantly correlated with the scores of FiRST, HAD, VAS-F, and HAQ(P< 0.05). In regression analysis, tender joint count, swollen joint count, PASI, pain VAS, and enthesitis were the MDA predictors in both genders. Conclusion: In patients with peripheral PsA, males are more likely to develop spondylitis while other extraarticular manifestations are similar. Female patients appear to have lower rates of remission and MDA and higher levels of disease activity. Female patients experience a more severe course of PsA, with higher levels of pain and fatigue, lower quality of life, and increased functional limitations. The predictors of MDA, i.e., tender joint count, swollen joint count, PASI, pain VAS, and enthesitis are similar between the two genders. (C) 2021 Societe francaise de rhumatologie.

This study aimed to evaluate fatigue and its relationship with disease parameters, functional disability, anxiety, depression, quality of life, and correlation with disease activity as determined by various scales. A total of 1028 patients (677 females, 351 males) with PsA who met the CASPAR criteria were included [Turkish League Against Rheumatism (TLAR) Network multicenter study]. The demographic features and clinical conditions of the patients were recorded. Correlations between fatigue score and clinical parameters were evaluated using the Disease Activity Score 28 (DAS28), Disease Activity in Psoriatic Arthritis (DAPSA), Clinical DAPSA (cDAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Fibromyalgia Rapid Screening Tool (FiRST), minimal disease activity (MDA), and very low disease activity (VLDA). Fatigue was assessed with the Functional Assessment of Chronic Illness Therapy (FACIT-F) and a 10-point VAS (VAS-F). The mean age of the patients was 47 (SD: 12.2) years, and the mean disease duration was 6.4 (SD: 7.3) years. The mean VAS-F score was 5.1 (SD: 2.7), with fatigue being absent or mild, moderate, and severe in 12.8%, 24.6%, and 62.5% of the patients, respectively. Fatigue scores were significantly better in patients with DAS28 remission, DAPSA remission, cDAPSA remission, MDA, and VLDA (p < 0.001). Fatigue scores significantly increased with increasing disease activity levels on the DAS28, DAPSA, and cDAPSA (p < 0.001). VAS-F scores showed correlations with the scores of the BASDAI, BASFI, PsAQoL, HAD-A, FiRST, pain VAS, and PtGA. FiRST scores showed fibromyalgia in 255 (24.8%) patients. FACIT-F and VAS-F scores were significantly higher in patients with fibromyalgia (p < 0.001). In regression analysis, VLDA, BASDAI score, FiRST score, high education level, HAD-Anxiety, and BMI showed independent associations with fatigue. Our findings showed that fatigue was a common symptom in PsA and disease activity was the most substantial predictor, with fatigue being less in patients in remission, MDA, and VLDA. Other correlates of fatigue were female gender, educational level, anxiety, quality of life, function, pain, and fibromyalgia.Öğe The impact of nail psoriasis on disease activity, quality of life, and clinical variables in patients with psoriatic arthritis: A cross-sectional multicenter study(Wiley, 2023) Cengiz, Gizem; Nas, Kemal; Keskin, Yasar; Kilic, Erkan; Sargin, Betul; Kasman, Sevtap Acer; Alkan, HakanAim Nail involvement is common in psoriatic arthritis. This study assesses clinical characteristics, nail psoriasis prevalence, and impact of nail psoriasis on disease activity in patients with psoriatic arthritis (PsA). Method This cross-sectional multicenter study was conducted by the Turkish League Against Rheumatism using PsA patients recruited from 25 centers. Demographic and clinical characteristics of PsA patients, such as disease activity measures, quality of life, and nail involvement findings were assessed during routine follow-up examinations. Patients were divided into two groups according to the presence or absence of nail psoriasis and compared using the chi(2) test or Fisher exact test for categorical variables and the t-test or Mann-Whitney U test for continuous variables. Results In 1122 individuals with PsA, 645 (57.5%) displayed nail psoriasis. The most frequent features of fingernails were ridges (38%), followed by pitting (21%) and onycholysis (19%). More females were present in both groups (with and without nail psoriasis; 64% vs 67%, P < 0.282). Patients with nail psoriasis were older, indicated more pain and fatigue, experienced greater swelling, tender joint counts, and skin disease severity, and had a higher disease activity score compared with those without nail psoriasis (all P < 0.05). Conclusion We demonstrate an increased prevalence of nail psoriasis observed in patients with psoriatic arthritis. Patients with nail involvement experience increased disease activity, lower quality of life, and diminished mental and physical status compared with those without nail involvement.Öğe Impact of obesity on quality of life, psychological status, and disease activity in psoriatic arthritis: a multi-center study(Springer Heidelberg, 2022) Gok, Kevser; Nas, Kemal; Tekeoglu, Ibrahim; Sunar, Ismihan; Keskin, Yasar; Kilic, Erkan; Sargin, BetulThis 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/m(2) 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.Öğe Inconsistencies of the Disease Activity Assessment Tools for Psoriatic Arthritis: Challenges to Rheumatologists(Elsevier France-Editions Scientifiques Medicales Elsevier, 2022) Gezer, Halise Hande; Duruoz, Mehmet Tuncay; Nas, Kemal; Kilic, Erkan; Sargin, Betul; Kasman, Sevtap Acer; Alkan, HakanObjective: Currently, concerning the evaluation of psoriatic arthritis (PsA), there is no agreement on a standardized composite index for disease activity that includes all relevant domains. The present study sought to assess the rates of remission (REM)/low disease activity (LDA) and disease states [minimal disease activity (MDA), very low disease activity (VLDA)] as defined by diverse activity scales (DAPSA, DAS28-ESR) in an attempt to display discrepancies across these assessment tools for peripheral PsA. Methods: The study involved 758 patients (496 females, 262 males; mean age 47,1 years) with peripheral PsA who were registered to the Turkish League Against Rheumatism (TLAR) Network. The patients were assessed using the DAS28-ESR, DAPSA, MDA, and VLDA. The overall yield of each scale was assessed in identifying REM and LDA. The presence or absence of swollen joints was separately analysed. Results: The median disease duration was 4 years (range 0-44 years). According to DAPSA and DAS28-ESR, REM was achieved in 6.9% and 19.5% of the patients, respectively. The rates of MDA and VLDA were 16% and 2.9%, respectively. Despite the absence of swollen joints, a significant portion of patients were not considered to be in REM (296 (39.1%) patients with DAS28-ESR, 364 (48%) with DAPSA, and 394 (52%) with VLDA). Conclusion: Patients with peripheral PsA may be assigned to diverse disease activity levels when assessed with the DAS28-ESR, DAPSA, MDA and VLDA, which would inevitably have clinical implications. In patients with PsA a holistic approach seems to be necessary which includes other domains apart from joint involvement, such as skin involvement, enthesitis, spinal involvement, and patient-reported outcomes.
