Fibromyalgia (FM) is a syndrome characterized by chronic widespread pain and the presence of specific tender points. The prevalence of FM has been estimated at 2-7 % of the general global population. The presence of FM in several rheumatic diseases with a structural pathology has been reported as 11-30 %. The objectives of this study were to determine the prevalence of FM and to evaluate the possible relationship between FM existence and disease activity among rheumatic diseases. The study group included 835 patients--197 rheumatoid arthritis (RA), 67 systemic lupus erythematosus (SLE), 119 ankylosing spondylitis (AS), 238 osteoarthritis (OA), 14 familial Mediterranean fever (FMF), 53 Behçet's disease (BD), 71 gout, 25 Sjögren's syndrome (SS), 20 vasculitis, 29 polymyalgia rheumatica (PMR), and two polymyositis (PM)--with or without FM. Recorded information included age, gender, laboratory parameters, presence of fatigue, and disease activity indexes. The prevalence of FM in patients with rheumatologic diseases was found to be 6.6 % for RA, 13.4 % for SLE, 12.6 % for AS, 10.1 % for OA, 5.7 % for BD, 7.1 % for FMF, 12 % for SS, 25 % for vasculitis, 1.4 % for gout, and 6.9 % for PMR. One out of two patients with PM was diagnosed with FM. Some rheumatologic cases (AS, OA) with FM were observed mostly in female patients (p = 0.000). Also, there were significant correlations between disease activity indexes and Fibromyalgia Impact Questionnaire scores for most rheumatologic patients (RA, AS, OA, and BD) (p < 0.05; respectively, r = 0.6, 0.95, 0.887, and 1). Concomitant FM is a common clinical problem in rheumatologic diseases, and its recognition is important for the optimal management of these diseases. Increased pain, physical limitations, and fatigue may be interpreted as increased activity of these diseases, and a common treatment option is the prescription of higher doses of biologic agents or corticosteroids. Considerations of the FM component in the management of rheumatologic diseases increase the likelihood of the success of the treatment.

Objectives. NLR (neutrophil-lymphocyte ratio) and PLR (platelet-lymphocyte ratio) are prognostic markers of diff erentiated thyroid cancers. In our study, we evaluated NLR, PLR and C-reactive protein (CRP) for predicting the occurence of diff erentiated thyroid cancer. Th is is the fi rst study that compares NLR and PLR to C-reactive protein indiff erantiated thyroid cancer not only papillary cancer but also folliculer cancer.Methods. Th is study includes 51 papillary carcinoma, 42 papillary microcarcinoma and 31 folliculer carcinoma patients attending to our outpatient Endocrinology Clinic at Erzurum Region Training and Research Hospital between 2009 and 2014. Th e control group include 50 age, sex and body mass index matched healty subjects. Blood counts and CRP were measured at the day before surgery. Th yroglobulin was measured aft er 6 months of operation.Results. Th ere were positive correlations between tumor diameter, age, white blood cell (WBC) and thyroglobulin levels. Th ere were also positive correlation between NLR, PLR and CRP levels.Conclusion. In our study, we found out that higher NLR and PLR was associated with higher levels of thyroglobulin which indicates worse survival. CRP levels were also associated with poorer tumor profi le but the determining rate was lower according to ROC analysis

Higher nesfatin-1 levels in PCOS women compared to control group may suggest a possibility that nesfatin-1 may play some role in the PCOS.

Fibromyalgia is a syndrome characterised by chronic widespread pain at multiple tender points, as well as joint stiffness and systemic symptoms. The aetiology and pathogenesis of fibromyalgia still remain unclear, although many contributory factors have been suggested. The presence of some common features between fibromyalgia and cardiovascular risk factors (e.g. depression and sleep disturbance) led to question of whether there is there a relationship between fibromyalgia and cardiovascular disease and/or atherosclerosis. Mean platelet volume, which is a determinant of platelet activation, is a newly emerging independent risk factor for cardiovascular disease.The present study was designed to evaluate levels of mean platelet volume in patients with fibromyalgia; the study population consisted of 283 individuals with this syndrome, who were compared with 72 healthy controls. Erythrocyte sedimentation rate, C-reactive protein, white blood cell count, platelet count and mean platelet volume levels were retrospectively recorded via the computerised patient database. The levels of mean platelet volume were significantly higher in the fibromyalgia group than in the control group (8.09 ± 0.84 fl and 7.73 ± 0.65 fl, respectively, p < 0.001). There were no statistical differences between groups with regard to platelet count and other parameters. These results suggest that an early atherosclerosis marker, mean platelet volume, is elevated in patients with fibromyalgia. This indicates increased platelet activation and therefore a higher risk of future cardiovascular disease.

Objective. Th e neutrophil-lymphocyte ratio (NLR), determined from peripheral blood, is accepted as an available and practical indicator of the systemic infl ammation. In this study, we aimed to determine whether the NLR was higher in euthyroid chronic autoimmune thyreotidis (CAT) patients compared to a healthy control group.Methods. A total of 112 patients were enrolled in this study, including 59 patients with euthyroid CAT on any form of therapy and 53 healthy controls. Th e CAT patients were similar in age to the healthy control group (mean 33.9±12.8 years versus 30.2±12.4 years, p=0.10). Measurements were available for the white blood cells (WBC), neutrophils, lymphocytes, platelets, C-reactive protein (CRP), thyroid peroxidase immune antibody (anti-TPO), and anti-thyroglobulin immune antibody (anti-TG). Th e NLR and platelet-lymphocyte ratio (PLR) were calculated. Diff erences between the CAT and control groups were tested using the student's t-test and the correlations were determined using Pearson's correlation coeffi cients.Results. Th ere were no diff erences between the CAT and control groups for WBCs (7.9±0.3 and 7.4±0.2, respectively; p=0.1) or neutrophils (5.5±0.3 and 5.4±1.1; p=0.9), but lymphocytes were higher in the CAT group (3.1±0.5 vs. 2.04±0.1; p=0.05) as was the NLR (4.0±0.7 vs. 2.0±0.1; p=0.01). Th e NLR was positively correlated with CRP (r=0.6, p<0.001), anti-TPO (r=0.3, p<0.001), anti-TG (r=0.3, p=0.006), WBCs (r=0.4, p<0.001), and the PLR (r=0.73, p<0.001). Th e PLR was also higher in the CAT than the control group (p=0.02).Conclusions. In this study, we found that NLR values were higher in euthyroid CAT patients than in a healthy control group and that NLR correlated with autoantibodies used to diagnose the disease.

The aim of this study was to assess mean platelet volume (MPV) and its relationship with disease activity in patients with Behçet's disease. Thirty-six patients with an age of 38.9 ± 11 (mean ± SD) years and 40 controls aged 36.5 ± 12 (mean ± SD) years were enrolled the study. Demographic data, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), MPV, clinical findings such as oral aphthae, genital aphthae, erythema nodosum, acne, central nervous system involvement, uveitis, arthritis and arthralgia were all recorded. The MPV value in patients with Behçet's disease was 8.06 ± 1.0 (mean ± SD) and the MPV value of the control participants was 7.45 ± 0.6 (mean ± SD). MPV was statistically higher in patients with Behçet's disease than in the controls (P = 0.003). There were also significant differences between patients and controls according to ESR and CRP values (P < 0.001 and P = 0.001, respectively). MPV was positively correlated with arthralgia (P < 0.001, r = 0.438), arthritis (P = 0.008, r = 0.307), erythema nodosum (P = 0.002, r =  0.354), central nervous system involvement (P = 0.002, r = 0.357), acne (P = 0.008, r = 0.312), genital aphthae (P < 0.001, r = 0.401) and oral aphthae (P = 0.001 r = 0.377). MPV can be easily obtained from the patients. It was a cheap and practical method. In the future, MPV may be used as a new marker to detect the activation of BD.
