    (Springer, 2014) Hamidi, Cihad; Batmaz, Ibrahim; Gumus, Hatice; Penbegül, Necmettin; Cetincakmak, Mehmet Guli; Tahtasiz, Mehmet; Bilici, Aslan
    Objective To evaluate the relationship between varicocele and ankylosing spondylitis (AS) via color duplex sonography (CDS). Methods Thirty male patients (age range 18-40 years, mean age 30.27 years) with AS and 30 male healthy controls (age range 20-36 years, mean age 27.23 years) were evaluated for varicocele using CDS. Results Vein diameter in right and left pampiniform plexus (PP) in the AS group was significantly higher than in the control group (p < 0.001 and p = 0.003, respectively). The incidence of varicocele was observed as 33.3 % in the AS group and 10 % in the control group. However, the difference was statistically significant (p = 0.028). The rate of right, left, and bilateral varicocele was 3.3 % (1 patient), 23.3 % (7 patients), and 6.6 % (2 patients), respectively, in the AS group, versus 0, 10, and 0 % in the control group (p = 1.000, p = 0.166, and p = 0.492, respectively). Conclusions The incidence of varicocele in AS patients is higher than in control subjects, and the difference is statistically significant. Therefore, varicocele must be taken into consideration and investigated in patients with AS.

    Elevated serum levels of high mobility group box protein 1 (HMGB1) in patients with ankylosing spondylitis and its association with disease activity and quality of life
    (Springer Heidelberg, 2013) Oktayoglu, Pelin; Em, Serda; Tahtasiz, Mehmet; Bozkurt, Mehtap; Ucar, Demet; Yazmalar, Levent; Nas, Kemal
    This study was carried out to determine the serum levels of high mobility group box protein 1 (HMGB1) in patients with ankylosing spondylitis (AS) and to evaluate its correlation with disease activity and quality of life. According to our knowledge, it is the first trial evaluating HMGB1 levels in AS. Serum samples of 30 patients (18 males and 12 females) with AS and 29 healthy controls (HC) (15 females and 14 males) were collected. HMGB1 levels were measured by enzyme-linked immunosorbent assay, activity of disease was assessed according to the Bath AS Disease Activity Index (BASDAI), and functional status of patients was evaluated with Bath AS Functional Index (BASFI). Modified Schober, chest expansion values and AS Quality of Life Questionnaire (ASQoL) scores were noted. The serum levels of HMGB1 were obtained significantly increased in AS patients compared to HC (p < 0.05). There was no significant correlation between HMGB1 levels and ESR (p > 0.05), and CRP (p > 0.05) values. BASDAI, BASFI and ASQoL scores were also not correlated with serum levels of HMGB1 (p > 0.05). Our results suggest that HMGB1 might play an important role in the pathogenesis of AS; however, it seems not to be a good candidate for reflecting disease activity, functional abilities and the quality of life in patients with AS; on the other hand, the increased levels of HMGB1 in patients may open a new dimension for targeting this cytokine as a new therapy option in AS.

    Investigation of the Effects of Leptin on the Cardiovascular System in Patients With Systemic Sclerosis
    (Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2013) Atilgan, Zuhal Ariturk; Islamoglu, Yahya; Tekbas, Ebru; Budulgan, Mahmut; Batmaz, Ibrahim; Tahtasiz, Mehmet; Yuksel, Hatice
    Objective: Cardiac involvement in systemic sclerosis can be seen, and often remains silent. Leptin, which is often associated with hypertension and regulation of sympathetic tone, has been reported to contribute to the development of atherosclerosis, endothelial dysfunction and thrombosis by acting directly. The aim of this study was to investigate the effects of leptin on the cardiovascular system in patients with systemic sclerosis. Materials and Methods: Twenty-seven patients with systemic sclerosis and 28 healthy subjects as a control group were included in the study. Clinical and laboratory parameters, 24-hour Holter ECG and ambulatory blood pressure monitorings were recorded and serum leptin levels were measured in all subjects. Results: Mean leptin levels were lower in patients with systemic sclerosis than in controls. In 24-hour ambulatory blood pressure Holter recordings, the mean systolic and diastolic blood pressure, daytime systolic and diastolic blood pressure, systolic and diastolic blood pressure values at night were lower in patients when compared with controls. There was no relationship between leptin and heart rate variability parameters. A positive correlation was found between leptin levels and 24-hour ambulatory blood pressure parameters. Conclusion: Decreased serum leptin levels and increased mean heart rate in patients with systemic sclerosis may be the result of increased sympathetic tone.

    Metabolic Syndrome in Patients With Ankylosing Spondylitis
    (Elmer Press Inc, 2011) Batmaz, Ibrahim; Karakoc, Mehmet; Sariyildiz, Mustafa Akif; Yazici, Selma; Tahtasiz, Mehmet; Atilgan, Zuhal; Cevik, Remzi
    Background: The objective of this study is to investigate the presence of metabolic syndrome (MS) in patients with ankylosing spondylitis (AS) and to evaluate its relationship with the clinical parameters. Methods: Fifty patients who presented to the Dicle University School of Medicine, Physical Therapy and Rehabilitation Outpatient Clinic and were diagnosed with AS according to the 1984 New York criteria were enrolled in this study. The control group consisted of 44 healthy control subjects. Assessment of the MS was made according to the diagnostic criteria specified in the National Cholesterol Education Program Adult Treatment Panel III Report (NCEP ATP III). Functional status and disease activity were evaluated using the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for AS. Results: MS was observed in 6 out of the 50 AS patients (12%) and in 2 out of the 44 controls (4.5%) (P > 0.05). However, the HDL cholesterol level (P = 0.006) was found as significantly lower in AS patients than the controls. No statistically significant differences were observed in the disease duration and functional and clinical activity indices between the AS patients with and without MS. Conclusions: Although the frequency of MS was observed to be higher in patients with AS than the controls in this study, the differences were statistically insignificant between the two groups.

    Relationship of the sexual functions with the clinical parameters, radiological scores and the quality of life in male patients with ankylosing spondylitis
    (Springer Heidelberg, 2013) Sariyildiz, Mustafa Akif; Batmaz, Ibrahim; Dilek, Banu; Inanir, Ahmet; Bez, Yasin; Tahtasiz, Mehmet; Em, Serda
    The aim of this study was to explore the impact of ankylosing spondylitis (AS) and the disease-related variables on the patients' sexual function according to the International Index of Erectile Function (IIEF) scoring system. A total of 70 sexually active male AS patients and 60 healthy controls were enrolled in this study. Their demographic data were evaluated, and the pain was assessed according to the visual analogue scale (VAS). Laboratory tests were conducted in order to measure the C-reactive protein (CRP) and erythrocyte sedimentation rates (ESR) of the patients. The disease activity was evaluated using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Functional statement was evaluated with the help of the Bath Ankylosing Spondylitis Functional Index (BASFI) and with the scores obtained from the spinal measurements with the Bath Ankylosing Spondylitis Metrology Index (BASMI). The Bath Ankylosing Spondylitis Radiology Index (BASRI) was used to evaluate the radiological damage. The disease-related quality of life was measured with the Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL). The anxiety and depression level of the patients was revealed through the Hospital Anxiety and Depression Scale (HADS). In comparison with the healthy control group, patients with AS had significantly lower scores in each of the 5 domains of the IIEF (p < 0.0001). The BASDAI, BASFI, BASMI, BASRI, ASQoL, HADS scores and CRP levels were negatively correlated with IIEF (p < 0.05). Orgasmic function and sexual desire scores were significantly lower in patients with peripheral arthritis (p < 0.05). No significant correlation was observed with the disease duration, smoking status, pain (VAS), and ESR levels when the total scores and the scores from the domains of IIEF were compared. The multivariate regression analyses indicated that BASFI and BASMI were independently associated with the sexual function. The sexual function is impaired in male patients with AS. This impairment in the sexual function is especially correlated with the BASFI and BASMI among the clinical and laboratory parameters.

    Serum levels of high mobility group box 1 protein and its association with quality of life and psychological and functional status in patients with fibromyalgia
    (Wiley, 2013) Oktayoglu, Pelin; Tahtasiz, Mehmet; Bozkurt, Mehtap; Em, Serda; Ucar, Demet; Yazmalar, Levent; Mete, Nuriye
    Aim: High mobility group box 1 protein (HMGB1) is a proinflammatory cytokine. Previous studies have suggested that HMGB1 can play an important role in the pathogenesis of many rheumatic diseases. The purpose of this study was to investigate the serum levels of HMGB1 in patients with fibromyalgia (FM) and its association with quality of life and psychological and functional status in these patients. Methods: Twenty-nine patients who met the 1990 American College of Rheumatology (ACR) criteria for the classification of FM and 29 healthy controls (HC) were included in the present study. Serum samples were collected from both the patients and the HC, and HMGB1 levels were measured by enzyme-linked immunosorbent assay (ELISA). The Fibromyalgia Impact Questionnaire (FIQ) was used to assess the disease severity and functional status in patients with FM. Furthermore, the Nottingham Health Profile was used to assess quality of life in all subjects, as well as the Hospital Anxiety and Depression Scale (HADS) to assess depression and anxiety. Results: The serum levels of HMGB1 protein were positively correlated with the FIQ scores in patients with FM (P = 0.002). Mean serum levels of HMGB1 were higher in patients with FM than in HC but this difference was not statistically significant. Conclusion: HMGB1 protein might be a good laboratory-sourced candidate for the assessment of functional status and disease severity in patients with FM.
