    The Effect on Anastomotic Leakage of Serum Zn, Cu Levels and Cu-Zn Ratio
    (1997) Aydin, M.; Guler, O.; Karaayvaz, M.; Sekeroglu, R.
    This study evaluated the influence of serum Zn and Cu levels on postoperative complication, following manual anastomosis of the alimentary track. Fifty seven vases of alimentary tract malignancy were included (22 stomach and 35 esophagus). Serum 2n and Cu levels were measured preoperatively and on the third, fifth and seventh postoperative days. Postoperative serum Zn levels were low in patients with anastomotic leakage, and there were significant differences in Zn levels between those with and without anastomotic leakage. However, there was no significant change in Cu levels. In the light of these findings, we conclude that Zn plays an effective role in anastomotic healing.

    Pantoprazole May Improve Beta Cell Function and Diabetes Mellitus
    (Springer, 2014) Inci, F.; Atmaca, M.; Ozturk, M.; Yildiz, S.; Koceroglu, R.; Sekeroglu, R.; Kebapcilar, L.
    Background Proton pump inhibitors induce hypergastrinemia by suppressing gastric acidity. Gastrin has incretin-like stimulating actions on beta cells. Proton pump inhibitors have been shown to decrease glycosylated hemoglobin. Aim We aimed to observe changes in beta cell function in diabetic and non-diabetic subjects given pantoprazole for an acid-related ailment. Methods Seventy-nine male patients (38 non-diabetic and 41 type-2 diabetic receiving only metformin therapy) were followed for 12 weeks after pantoprazole 40 mg/day was given. Fasting plasma glucose, HbA1c, fasting insulin, Pancreatic B cell function (HOMA-B), proinsulin and c-peptide levels were measured before and after the treatment. Results In non-diabetic patients (n = 38), FPG decreased, whereas c-peptide, log-HOMA-B, increased significantly (p = 0.002, p = 0.03, p = 0.042, respectively) after 12 weeks of pantoprazole administration. In type 2 diabetic patients, FPG, HbA1c and weight decreased, whereas log-HOMA-B, c-peptide and log-proinsulin levels increased significantly after pantoprazole treatment (p = 0.003, p = 0.007, p < 0.001; p < 0.001; p = 0.017, p = 0.05, respectively). After pantoprazole treatment, pancreatic B-cell function was correlated with c-peptide and insulin and inversely with FBG and HbA1c levels in the whole group (r = 0.37, p = 0.001; r = 0.60, p < 0.001, r = -0.29, p = 0.011 and r = -0.28, p = 0.013, respectively). After pantoprazole treatment, HbA1c was correlated with FBG (r = 0.75, p < 0.001) and inversely with only log-HOMA-B level (r = -0.28, p = 0.013). Conclusions Pantoprazole administration seems to correlate with increased beta cell function. Pantoprazole administration improves HbA1c, HOMA-B, c-peptide and proinsulin levels. Since beta cell loss plays a significant role in the pathogenesis of type 2 diabetes, PPI-based therapies may be useful in the treatment of diabetes.
