    Assessment of the New 2012 EULAR/ACR Clinical Classification Criteria for Polymyalgia Rheumatica: A Prospective Multicenter Study
    (J Rheumatol Publ Co, 2016) Ozen, Gulsen; Inanc, Nevsun; Unal, Ali Ugur; Bas, Seda; Kimyon, Gezmis; Kisacik, Bunyamin; Onat, Ahmet Mesut
    Objective. To assess the performance of the new 2012 provisional European League Against Rheumatism (EULAR)/ American College of Rheumatology (ACR) polymyalgia rheumatica (PMR) clinical classification criteria in discriminating PMR from other mimicking conditions compared with the previous 5 diagnostic criteria in a multicenter prospective study. Methods. Patients older than 50 years, presenting with new-onset bilateral shoulder pain with elevated acute-phase reactants (APR), were assessed for the fulfillment of the new and old classification/diagnostic criteria sets for PMR. At the end of the 1-year followup, 133 patients were diagnosed with PMR (expert opinion) and 142 with non-PMR conditions [69 rheumatoid arthritis (RA)]. Discriminating capacity, sensitivity, and specificity of the criteria sets were estimated. Results. Discriminating capacity of the new clinical criteria for PMR from non-PMR conditions and RA as estimated by area under the curve (AUC) were good with AUC of 0.736 and 0.781, respectively. The new criteria had a sensitivity of 89.5% and a specificity of 57.7% when tested against all non-PMR cases. When tested against all RA, seropositive RA, seronegative RA, and non-RA control patients, specificity changed to 66.7%, 100%, 20.7%, and 49.3%, respectively. Except for the Bird criteria, the 4 previous criteria had lower sensitivity and higher specificity (ranging from 83%-93%) compared with the new clinical criteria in discriminating PMR from all other controls. Conclusion. The new 2012 EULAR/ ACR clinical classification criteria for PMR is highly sensitive; however, its ability to discriminate PMR from other inflammatory/noninflammatory shoulder conditions, especially from seronegative RA, is not adequate. Imaging and other modifications such as cutoff values for APR might increase the specificity of the criteria.

    Incidence of Cyclophosphamide-induced Urotoxicity and Protective Effect of Mesna in Rheumatic Diseasesle
    (J Rheumatol Publ Co, 2015) Yilmaz, Neslihan; Emmungil, Hakan; Gucenmez, Sercan; Ozen, Gulsen; Yildiz, Fatih; Balkarli, Ayse; Kimyon, Gezmis
    Objective. To assess bladder toxicity of cyclophosphamide (CYC) and uroprotective effect of mesna in rheumatic diseases. Methods. Data of 1018 patients (725 women/293 men) treated with CYC were evaluated in this retrospective study. All of the following information was obtained: the cumulative CYC dose, route of CYC administration, duration of therapy, concomitant mesna usage, and hemorrhagic cystitis. Cox proportional hazard model was used for statistics. Results. We identified 17 patients (1.67%) with hemorrhagic cystitis and 2 patients (0.19%) with bladder cancer in 4224 patient-years. The median time for diagnosis to hemorrhagic cystitis was 10 months (4-48) and bladder cancer was 8 years (6-10.9). There were 583 patients (57.2%) who received mesna with intravenous CYC therapy. We observed similar incidence rate for hemorrhagic cystitis in both patient groups concomitantly treated with or without mesna [9/583 (1.5%) vs 8/425 (1.8%) respectively, p = 0.08]. Cumulative CYC dose (HR for 10-g increments 1.24, p < 0.001) was associated with hemorrhagic cystitis. Conclusion. Cumulative dose was the only risk factor for hemorrhagic cystitis in patients treated with CYC. No proof was obtained for the uroprotective effect of mesna in our cohort.

    Subclinical Atherosclerosis in Systemic Sclerosis: Not Less Frequent Than Rheumatoid Arthritis and Not Detected With Cardiovascular Risk Indices
    (Wiley, 2016) Ozen, Gulsen; Inanc, Nevsun; Unal, Ali U.; Korkmaz, Fatmanur; Sunbul, Murat; Ozmen, Mustafa; Akar, Servet
    Objective. To determine the frequency of subclinical atherosclerosis in patients with systemic sclerosis (SSc; scleroderma) compared to healthy subjects (HS) and rheumatoid arthritis (RA) patients and to determine the ability of cardiovascular (CV) risk indices in detecting SSc patients with subclinical atherosclerosis. Methods. A total of 110 SSc patients (102 females and 8 males, mean +/- SD age 50.5 +/- 11.9 years), 110 age-and sex-matched RA patients, and 51 HS without CV disease were examined with ultrasonography (US). Carotid intima-media thickness (cIMT) >0.90 mm and/or carotid plaques were used as the gold standard for subclinical atherosclerosis (US+). Systematic Coronary Risk Evaluation (SCORE), QRisk II, and 2013 American College of Cardiology (ACC)/American Heart Association (AHA) CV risk indices were calculated. Results. Twenty-one (19.1%) SSc patients, 24 (21.8%) RA patients, and 3 (5.9%) HS had subclinical atherosclerosis (SSc versus RA: P=0.62, SSc versus HS: P=0.029). cIMT in SSc was higher compared to HS (0.68 +/- 0.15 mm versus 0.61 +/- 0.10 mm; P=0.008) but similar to RA patients (0.66 +/- 0.14 mm; P=0.82). Subclinical atherosclerosis in SSc was associated with age (odds ratio [OR] 1.07, P=0.013), elevated erythrocyte sedimentation rate (OR 3.4, P=0.045), and pulmonary arterial hypertension (OR 4.27, P=0.012). Concerning CV risk indices, of the 21 US+ SSc patients only 0, 3 (14.2%), and 6 (28.6%) were classified as high CV risk according to SCORE, QRisk II, and ACC/AHA risk indices, respectively. Conclusion. Subclinical atherosclerosis in SSc patients is more frequent than in HS, but is as frequent as in RA patients in which accelerated atherosclerosis is clearly defined. CV risk indices for the general population are considerably insufficient to detect SSc patients with atherosclerosis.
