Öğe Changes in Serum Levels of ADMA, SDMA and L-NMMA with Helicobacter Pylori Eradication(AVES, 2017) Baldane, Süleyman; Korkmaz, Hüseyin; İpekci, Süleyman Hilmi; Sözen, Mehmet; Abuşoğlu, Sedat; Akar, Tarık; Ünlü, AliObjective: Increased asymmetric dimethylarginine (ADMA) levels are associated with reduced nitric oxide (NO) levels in many systems, particularly the cardiovascular system, and cause adverse effects. The objective of this study is to evaluate the effect of eradication therapy in patients infected with Helicobacter pylori (H. pylori) on the serum level of ADMA and other metabolic products of methylarginine. Methods: Patients who were found positive both in urea breath tests and stool antigen tests were considered to have H. pylori infection. These patients received eradication therapy for 14 days (twice daily pantoprazole 40 mg, twice daily amoxicillin 1000 mg, and twice daily clarithromycin 500 mg). Blood samples were taken to measure serum ADMA, symmetric dimethylarginine (SDMA), and N-monomethyl-Larginine (L-NMMA) levels before eradication therapy and 3 months after the therapy for patients for whom eradication was achieved. Results: A total of 23 of the 45 patients included in the study were female, whereas 22 were male. The mean age of the patients was 32.4 +/- 8 years. Significant reductions in the serum ADMA, SDMA, and L-NMMA levels of the patients were observed post-eradication therapy versus pre-eradication therapy. Conclusion: This study demonstrated significant reductions in serum ADMA, SDMA, and L-NMMA levels with H. pylori eradication. Further extensive long-term studies are needed to evaluate the positive effects that reduced serum ADMA, SDMA, and L-NMMA levels after H. pylori eradication can have on all systems, particularly the cardiovascular system.Öğe Examining the relationship between Vitamin D levels and Helicobacter pylori infection and its effect on the hypothalamic-pituitary-adrenal axis in dyspeptic patients(Ondokuz Mayis Universitesi, 2015) Korkmaz, Hüseyin; İpekci, Süleyman Hilmi; Baldane, Süleyman; Sözen, Mehmet; Abuşoğlu, Sedat; Kebapcılar, LeventThe purpose of this study was to determine whether or not Helicobacter pylori (H. pylori) infection affects the hypothalamic-pituitary-adrenal (HPA) axis and to evaluate the association between vitamin D levels with H. pylori infected and eradicated patients. The glucagon stimulation test (GST) was used to assess the HPA gland axis. An H. pylori infection was diagnosed based on the rapid urease test and histology. All infected patients received triple eradication therapy. Three months after the treatment, 14C urea breath test was reinstituted, and GST was repeated in patients who were negative for H. pylori. Of the 43 patients, 20 (46%) were found to have a lower mean value of peak cortisol than normal responses to the GST in the H. pylori-infected subjects. In 29 subjects, H. pylori infection was successfully eradicated. Twelve (41%) out of 29 subjects were defined as having a blunted GST response and 17 (%59) subjects had normal HPA axis response to GST in the H. pylori-eradicated subjects. A significant correlation between low 25-hydroxyvitamin D3 (25(OH)D3) level and low peak cortisol response to GST was identified in the H. pylori-infected subjects. After H. pylori eradication, the positive correlation between 25(OH)D3 level and high peak cortisol response to GST was also identified. Mean 25(OH)D3 levels were lower in the H. pylori-infected subjects than in the H. pylori-eradicated subjects. Our results indicate an increased prevalence of blunted glucocorticoid response to GST in patients with infected H. pylori. Vitamin D deficiency is also common in the H. pylori-infected subjects and associated with blunted glucocorticoid response. These findings suggest that H. pylori eradication increases the cortisol response to GST. Vitamin D supports adrenal/cortisol production whereby a deficiency can result blunted glucocorticoid response to GST in patients with infected H. pylori. © 2015 OMU.Öğe Gestasyonel diabetes mellitus tanısında bir biyobelirteç olarak serum prokalsitonin düzeyi(2018) Baldane, Süleyman; İpekci, Süleyman Hilmi; Kebapcılar, Ayşegül; Abuşoğlu, Sedat; Öztürk, Bahadır; Ünlü, Ali; Çelik, Çetin; Kebapcılar, LeventAmaç: Bu çalışmanın amacı gestasyonel diabetes mellitus hastalarında ve sağlıklı gebelerde serum prokalsitonin düzeylerini karşılaştırmak ve prokalsitonin düzeyinin diğer metabolik parametreler ile ilişkisini değerlendirilmesidir.Gereç ve Yöntem: Endokrinoloji Bilim Dalı polikliniğine başvuran 142 gebe çalışmaya dahil edildi.

Bu sonuç kronik düşük-dereceli inflamasyonun gestasyonel diabet mellitus patogenezinde önemli role sahip olduğu bilgisini desteklemektedir.

METHODS: A total of 76 pregnant women were included in the study. Thirty-five of the pregnant women were included in GDM group according to the results of oral glucose tolerance tests (OGTT) and 41 of them were included in the control group. RESULTS: In the group with GDM, SFRP4 value was found to be significantly higher than that of the control group (5.59 +/- 3.32 ng/mL vs 4.05 +/- 2.15 ng/mL; p = 0.017). Women with GDM had significantly higher serum prorenin levels compared with control group [737 (427-1339) pg/mL vs. 535 (376-725) pg/mL; p = 0.009]. There was a significant positive association between prorenin and SFRP4 levels in GDM (r = 0.91; p < 0.001) and control groups (r = 0.42; p = 0.002) and whole pregnancies (r = 0.75; p = 0.002). CONCLUSION: We have shown that prorenin and SFRP4 were significantly elevated in GDM patients when compared to healthy control group. Furthermore, we found that there was a positive correlation between prorenin and SFRP4 (Tab. 1, Fig. 2, Ref. 38).

Methods We carried out a cross-sectional study by enrolling 81 pregnant women with GDM and 38 pregnant women without GDM. Results Maternal and cord blood neopterin levels were higher in women with GDM. There was a significant positive association between fasting blood glucose levels and maternal serum neopterin levels. The results of 50-g oral glucose challenge tests revealed a correlation between maternal and cord neopterin levels. Pregnancies complicated by GDM exhibited lower fetal Apgar scores than those of control subjects. The levels of cord blood neopterin were inversely correlated with an fetal Apgar score of 1 min in patients with GDM. Conclusions Patients with GDM had higher maternal and cord blood neopterin levels, and the cord blood neopterin levels are inversely associated with lower Apgar scores in women with GDM. The neopterin levels might be potential predictors of low fetal Apgar scores in women with GDM.
