    Association of adverse outcomes of intrahepatic cholestasis of pregnancy with zonulin levels
    (Taylor & Francis Inc, 2021) Deniz, Cigdem Damla; Ozler, Sibel; Sayin, Fatma Kubra
    Our aim was to investigate serum zonulin levels in intrahepatic cholestasis of pregnancy (ICP) and to determine the usefulness of zonulin in ICP follow-up. A prospective case-control study was carried out which included 88 pregnant women (44 patients with ICP and 44 controls). Maternal serum samples obtained from all participants and zonulin levels were determined by enzyme-linked immunosorbent assay (ELISA). Compared with controls, women with ICP had significantly higher zonulin levels (mean 0.728 +/- 0.520 ng/mL vs. 1.303 +/- 0.63 ng/mL, p 001). According to the receiver operating characteristic (ROC) analysis performed for the predictive value of zonulin levels for ICP, the area under the curve (AUC) was 0.761 (95% CI: 0.661-0.860). Multivariable logistic regression analysis revealed serum zonulin levels was independently associated with adverse perinatal outcomes (OR = 1.278, 95% CI: 0.232-7.041), severity ICP (OR: 7.535, 95% CI: 1.597-13.553) and also unresponsiveness to treatment in ICP (OR: 4.178, 95% CI: 0.929-8.784). IMPACT STATEMENT What is already known on this subject? Zonulin is a regulator protein that increases the intestinal permeability by modulating the intercellular tight junctions (TJ). It is the only physiological protein known to control intestinal permeability and damage of the intestinal barrier is one of the causes of absorption disorders, inflammation and autoimmunity. ICP is a relatively non-threatening condition to women but is linked with a higher risk of preterm delivery, foetal distress and foetal death. What do the results of this study add? This study showed that increased levels of zonulin are associated with adverse perinatal outcomes, severity of ICP and unresponsiveness to treatment in ICP. What are the implications of these findings for clinical practice and/or further research? Focussing on preservation of intestinal permeability may be an alternative preventive strategy to reduce the adverse perinatal outcomes and severity of ICP. Further longitudinal studies are needed to verify the relationships among zonulin levels and pregnancy-related diseases.

    Associations between night eating syndrome and metabolic parameters in pregnant women
    (Galenos Yayincilik, 2019) Deniz, Cigdem Damla; Ozler, Sibel; Sayin, Fatma Kubra; Eryilmaz, Mehmet Ali
    Objective: In this study, we aimed to evaluate the incidence of night eating in pregnancy and the relationship between night eating scores and nutritional status, insulin resistance, and lipid profile in pregnant women. Materials and Methods: In this study, 148 pregnant women who presented to the Gynecology and Obstetrics Clinics at Konya Training and Research Hospital in Konya were divided into two groups according to their night eating scores. These two groups were compared in terms of their nutritional attitudes and metabolic parameters. Results: Comparisons of participants meeting night eating syndrome (NES) scores versus women without NES indicated that patients with NES exhibited fever hunger at breakfast time, more breakfast skipping (p<0.05) than those without NES. Also homeostatic model assessment insulin resistance, insulin, and high-density lipoprotein cholesterol parameters were significantly higher in pregnant women in the NES group (p<0.05). Also, correlations were found between higher night eating questionnaire total scores and higher HbA1c, insulin resistance, insulin, and more breakfast skipping. Conclusion: The results of this study suggest that night eating symptoms during pregnancy may increase and this is able to effect glucose metabolism.
