    Elevated neutrophil-lymphocyte ratio in patients with euthyroid chronic autoimmune thyreotidis
    (Institute of Experimental Endocrinology, 2016) Keskin H.; Kaya Y.; Cadirci K.; Kucur C.; Ziypak E.; Simsek E.; Carlioglu A.
    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 coefficients. 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. © 2016, Institute of Experimental Endocrinology.

    New pathway in rheumatic mitral valve disease: Cytochrome P450 and glutathione S transferase isozyme expression
    (De Gruyter Open Ltd, 2020) Simsek E.; Simsek G.; Soyal M.F.T.; Kaygin P.; Oguztuzun S.; Duzgun A.C.; Sarialtin S.
    Objective: Cytochrome P450 (CYP)1A1, glutathione S-transferase pi (GSTP1) and omega (GSTO1) isozymes were evaluated and compared in patients with the diagnosis of rheumatic mitral valve disease and ischemic mitral valve insufficiency to find out the relationship of the oxidative stress with rheumatic mitral valve disease. Materials and methods: The control group consisted of patients operated on due to ischemic mitral valve insufficiency (group I, n:14) while study group consisted of the patients operated on with the diagnosis of rheumatic mitral valve disease (group II, n:29). Mitral valve materials were stained with hematoxylin and eosin. CYP1A1, GSTP1, and GSTO1 immunohistochemical markers were studied. Results: 20.7% of GSTP1 isozyme protein expression was seen in the study group; however, no expression was detected in the control group. This finding was statistically significant in terms of GSTP1 isozyme. No statistically significant differences in the level of GSTO1 and CYP1A1 protein expression between the study and control groups were observed. Conclusion: In this study, we found out that GSTP1 isozyme may be related to rheumatic mitral valve disease. A strategy that would help prevent oxidative stress in patients with rheumatic mitral valve disease can be a so valuable means to affect disease progression. © 2020 De Gruyter. All rights reserved.
