    In Behcet's disease (BD) and Brucellosis, joint involvement is very common and it may share similarities with rheumatoid arthritis (RA). Anti-cyclic citrullinated peptides (CCP) are evaluated as more specific autoantibodies than rheumatoid factor (RF) in RA. The aim of this study is to determine whether anti-CCP antibodies are useful in the differential diagnosis of RA from other arthritis or not. 153 serum samples were used in the study; 34 from RA patients, 26 from brucellar arthritis, 20 from BD with arthritis, 41 from BD without arthritis and 32 from healthy controls. In vitro quantitative, anti-CCP levels were measured by using fluoroenzyme-immunoassay (FEIA) method. Among RA patients, 73.5% were anti-CCP-positive and 70.5% were RF-positive. While there was a statistical difference in the anti-CCP and RF positivity rates between RA and brucellar arthritis patients, BD patients and healthy controls (p = 0.0001), there was no statistical difference between BD patients with arthritis and BD patients without arthritis. Also none of the Brucellar arthritis patients was positive for anti-CCP antibodies, one of them were positive for RF. Our results indicate that anti-CCP antibodies are not associated with brucellar arthritis or BD with joint involvement and since they show high specificity and good sensitivity for RA, they can be evaluated as a better marker than RF especially for the differentiation of RA from other types of arthritis such as BD and brucellar arthritis.

    (TURKISH LEAGUE AGAINST RHEUMATISM, 2013) Kutsal, Yesim Gokce; Savas, Serpil; Inanici, Fatma; Ozdemir, Oya; Karahan, Sevilay; Dogan, Asuman; Hizmetli, Sami
    Objectives: This study aims to identify the frequency of clinical risk factors associated with osteoporosis in postmenopausal women. Patients and methods: In this cross-sectional, observational, multicenter study, a total of 730 postmenopausal women were assessed for risk factors associated with osteoporosis. The assessment included a standardized questionnaire which recorded the following clinical risk factors: family and personal histories of fractures, prolonged immobilization, sun exposure, lifelong sedentary lifestyle, smoking history, low calcium intake in childhood and adulthood, excessive caffeine intake, high sodium intake, inadequate protein intake, number of pregnancies, age at menopause, the presence of premature menopause, primary and secondary amenorrhea, medical conditions, and chronic use of prescription drugs. Results: The most frequent clinical risk factors for osteoporosis were inadequate sun exposure (53.3%), current sedentary lifestyle (52.9%), low calcium intake in adulthood (45.1%) and childhood (41.9%), and sedentary lifestyle in adolescence (27.9%). A total of 707 patients (96.5%) described more than one risk factor, while 74.3% of the patients reported one clinical risk factor at least for secondary osteoporosis. Conclusion: Adequate sun exposure and proper intake of dietary calcium beginning in childhood combined with lifelong daily physical activity may play a role in preventing osteoporosis in postmenopausal women. In addition, physicians should be aware of the high probability of secondary osteoporosis in this patient group.
