To evaluate the T helper 17 (Th17) axis and its relation to tumor necrosis factor (TNF) alpha blockage and disease activity in ankylosing spondylitis (AS). The study included 127 AS patients (100M/27F) and 38 (27M/11F) controls. Spinal mobility was assessed by the bath ankylosing spondylitis metrology index (BASMI). Patients were also evaluated with the bath ankylosing spondylitis functional (BASFI) and bath ankylosing spondylitis disease activity index. Cytokines including IL-6, IL-12, TGF-β, IL-17A, and IL-23 were measured in serum sample using commercially available ELISA kits. Cytokines including IL-6, IL-12, TGF-β, IL-17, and IL-23 were significantly higher in the AS patients than the controls (P < 0.05). The Th-17-related cytokines were not different between patients treated with anti-TNF and conventional therapies (P > 0.05). Cytokines were also similar between patients with active and inactive disease (P > 0.05). On correlation analysis, IL-17 was correlated with IL-23 and IL-12 (P < 0.05) and IL-23 showed correlations with IL-12 and BASMI (P < 0.05). We found serum levels of Th-17-related cytokines to be significantly increased in the sera of AS patients. Disease activity and treatment type did not affect the level of these cytokines.

Background/Aim:Galectins affect diverse physiological and pathophysiological processes such as development, inflammation, and tumor growth. We aimed to compare serum galectin-3 levels in three patient groups with chronic hepatitis B and C virus (HBV, HCV), cirrhosis secondary to HBV or HCV, and hepatocellular carcinoma (HCC) secondary to HBV or HCV and evaluate the role of galectin-3 during HCC progression.Patients and Methods:Nineteen patients with hepatocellular cancer, 22 patients with cirrhosis, and 24 patients with chronic hepatitis B and C were included in this study. Serum galectin-3 levels in different liver diseases were assessed by enzyme-linked immunosorbent assay.Results:The mean galectin-3 levels were 4.61 ng/mL (±2.32) in HCC patients, 5.68 ng/mL (±2,2) in cirrhotic patients, 1.98 ng/mL (±1.50) in chronic viral hepatitis group. There were no statistical differences between HCC and cirrhotic patients (P = 0.5), but lower in chronic hepatitis group statistically compared with cirrhosis and HCC (P < 0.001, P = 0.002, respectively). In case of cirrhotic patients, galectin-3 levels were significantly higher in patients with cirrhosis secondary to HCV compared with HBV (P = 0.03). When we evaluated galectin-3 levels in HCC patients, it was found to be 3.92 ng/mL in HCC secondary to hepatitis B and 5.37 ng/mL in HCC secondary to hepatitis C.Conclusion:Serum galectin-3 levels in patients with chronic HBV or HCV may guide us about progression to cirrhosis or HCC and prognosis of the disease. Especially, galectin-3 levels may be more pronounced in case of HCV.

We aimed to evaluate some of the vascular biomarkers in newly diagnosed, colchicine naive familial Mediterranean fever (FMF) patients. Our primary aim was to investigate the effect of regular colchicine treatment on these variables. Twenty-four (12 males [M] and 12 females [F], 33.3 ± 13.4 years) newly diagnosed FMF patients were included in the study. These patients were started on colchicine treatment following the initial assessment and were studied again no earlier than 2 months. Five patients were lost to follow-up, and assessment of the on-treatment patients was performed on the remaining 19 patients (8 M and 11 F, 33.6 ± 11.8 years). There were 19 healthy subjects (11 M and 8 F, 32.2 ± 7.2 years) who served as a control group. Cellular adhesion molecules (CAMs; soluble intercellular adhesion molecule-1 [sICAM-1] and soluble CD146 [sCD146]), plasminogen activator inhibitor-1 (PAI-1), fetuin-A and hs-CRP were studied. Examinations were performed on attack-free periods. The levels of hs-CRP, fetuin-A, sICAM-1, and PAI-1 were significantly higher in newly diagnosed patients compared to those of controls (P < 0.05). All studied parameters were significantly downregulated after regular colchicine therapy (P < 0.05). Comparison of on-treatment data with controls showed that the levels of the vascular biomarkers, except sCD146, were similar between the groups (P > 0.05). On-treatment sCD146 was found significantly lower than the controls (P < 0.05). In regression analysis, none of the independent variables in the model significantly predicted the vascular biomarkers (P > 0.05). Administration of therapeutic doses of colchicine markedly reduces vascular injury parameters and normalizes the values in FMF.

High insulin and leptin levels, important factors that were previously shown to be related to breast cancer outcome, and insulin resistance may be increased in taxane based chemotherapy regimen. These data may have broad implications for diet and lifestyle strategies for the prevention and treatment of cancers.

Circulating EMP and PMP, known to be indicators and mediators of vascular injury, were not significantly altered in men with AS who did not have classical cardiovascular risk factors. Significantly downregulated MP in patients receiving biological agents suggested that anti-TNF treatment may have a beneficial effect on vascular function in AS.
