    Lower plasma pantoprazole level predicts Helicobacter pylori treatment failure in patients with type 2 diabetes mellitus
    (Wiley, 2015) Sapmaz, Ferdane; Kalkan, Ismail H.; Suslu, Incilay; Demirci, Huseyin; Atasoy, Pinar; Guliter, Sefa
    ObjectiveWe aimed to compare the plasma pantoprazole level (PPL) between patients with type 2 diabetes mellitus and non-diabetic patients during Helicobacter pylori (H. pylori) eradication treatment and to explore the role of PPL in predicting the treatment success rates. MethodsThis study included 40 diabetic and 40 non-diabetic treatment-naive H.pylori-infected patients. Bismuth-based standard quadruple treatment for H.pylori eradication was used for 14 days in both groups. PPL was measured using the square-wave voltammetry method. ResultsH.pylori eradication rate (60.0% vs 87.5%, P=0.005) and PPL (0.25 0.03 g/mL vs 0.34 +/- 0.03 g/mL, P < 0.001) was significantly lower in the diabetic group compared with the controls. Patients with treatment failure had lower PPL than those with successful treatment (P<0.001). The receiver operating characteristics curve demonstrated that PPL had a significant predictive value for the outcome of H.pylori eradication. ConclusionType 2 diabetic patients had lower PPL than the non-diabetic controls, which led to their lower H. pylori eradication rates.

    A very rare cause of markedly elevated CA 19.9: Autoimmune hepatitis
    (Taylor & Francis Ltd, 2016) Sapmaz, Ferdane; Kalkan, Ismail H.; Kisa, Ucler; Guliter, Sefa
    Carbohydrate antigen 19.9 (CA 19.9) is a specific tumour marker of the biliary, pancreatic and gastrointestinal tracts. Autoimmune hepatitis is a chronic immune-mediated liver disorder characterised by female predominance. We report a case of approximately 30-fold increased serum CA 19.9 in a 57-year-old woman who was diagnosed with autoimmune hepatitis. She had no evidence of any malignant disease in pancreatobiliary or gastrointestinal tracts. CA 19.9 levels decreased to normal levels with immunosuppressive treatment. Markedly elevated serum CA 19.9 levels might be encountered with benign liver diseases such as autoimmune hepatitis.
