Öğe Do We Need to Replace GH to Correct Anemia in Hypopituitarism?(ENDOCRINE SOC, 2014) Kulaksizoglu, Mustafa; Ipekci, Suleyman Hilmi; Gonulalan, Gulsum; Ozturk, Mine; Kaya, Ahmet; Gonen, Mustafa Sait; Cakir, Mehtap[Abstract not Available]Öğe Is the Mean Platelet Volume a Predictive Marker of a Low Apgar Score and Insulin Resistance in Gestational Diabetes Mellitus? A Retrospective Case-Control Study(PREMCHAND SHANTIDEVI RESEARCH FOUNDATION, 2016) Kebapcilar, Levent; Kebapcilar, Ayse Gul; Ilhan, Tolgay Tuyan; Ipekci, Suleyman Hilmi; Baldane, Suleyman; Pekin, Aybike; Kulaksizoglu, MustafaIntroduction: Gestational diabetes is defined as various degrees of glucose intolerance diagnosed or detected for the first time during pregnancy and is the most common metabolic complication of pregnancy. Early diagnosis and adequate treatment are important to prevent complications. Preeclampsia, polyhydramnios, fetalmacrosomia, and operative delivery are some of the complications seen in pregnant women diagnosed with Gestational Diabetes Mellitus (GDM). Aim: The present study was designed to determine whether there was an association between Mean Platelet Volume (MPV) in predicting poor fetal outcome, insulin resistance, neonatal Apgar scores and gestational age for women with GDM. Materials and Methods: In this retrospective study, we enrolled 101 pregnant women with GDM together with a group of 138 healthy controls. MPV, insulin and homeostatic model assessment (HOMA-IR) values were measured at 24-28 weeks of the pregnancy. An independent samples t-test was used to compare MPV values. Multivariate linear regression models were used to establish relations between MPV values, HOMAIR, insulin levels and Apgar score. Results: There was a significant positive correlation between MPV values, HOMA-IR and Insulin levels and a negative correlation with Apgar score at 1 min and 5 min in the GDM group (r=0.227, p=0.02; r=0.206, p=0.03; r=-0.485, p<0.001; and r=-0.399, p<0.001, respectively). In the multivariate logistic regression analysis, a high MPV value was most consistently associated with a low Apgar 1 min score (beta=-0.387, p=0.003) in the GDM group. An MPV of >8.0 fL had a sensitivity of 82% and a specificity of 75% for the prediction of GDM. Conclusion: We investigated the potential of MPV values in predicting low Apgar scores and insulin resistance in women with GDM.Öğe Is there a link between premature ovarian failure and serum concentrations of vitamin D, zinc, and copper?(LIPPINCOTT WILLIAMS & WILKINS, 2013) Kebapcilar, Ayse Gul; Kulaksizoglu, Mustafa; Kebapcilar, Levent; Gonen, Mustafa Sait; Unlu, Ali; Topcu, Ali; Demirci, FatihObjective: The risk of primary ovarian insufficiency (POI) increases in association with autoimmune conditions. Adequate intake of vitamin D (vit D) and trace elements is required for the immune system to function efficiently. The aim of this study was to evaluate vit D, zinc, and copper blood levels in women with POI who had given birth to at least one child and in women with normal menstrual cycles. Methods: This was a cross-sectional, case-control study involving 63 participants divided into two groups: the study group, which is composed of 35 women with POI, and the control group, which is composed of 28 women with normal menstrual cycles. Serum concentrations of zinc, vit D, and copper were determined for each participant. Results: Women with POI had significantly higher serum copper levels and copper-to-zinc ratio but significantly lower serum vit D and zinc levels when compared with the healthy control group. Serum follicle-stimulating hormone levels were inversely correlated with zinc and vit D levels and positively correlated with the copper-to-zinc ratio and copper levels. Vit D levels were inversely correlated with follicle-stimulating hormone levels, copper-to-zinc ratio, and copper levels and positively correlated with zinc levels. Conclusions: Most women with POI are deficient in vit D. Zinc, copper, and vit D seem to correlate with hormonal status in the participants. The present study may generate hypotheses for future studies that will investigate the possible mechanisms behind alterations in trace elements and vit D deficiency in women with POI and whether these changes could be used to screen for the risk of developing POI.Öğe Treatment of recurrent hypoglycemia with plasmapheresis and steroid in nondiabetic patient(PERGAMON-ELSEVIER SCIENCE LTD, 2013) Kulaksizoglu, Mustafa; Gonen, Mustafa Sait; Kebapcilar, Levent; Sahin, Fatih; Demirci, Fatih; Topcu, AliWe recently encountered a 35-year old man who suffered from frequent hypoglycemia. His blood test revealed the presence of high and suppressed level of insulin with supressed C-peptide levels, hypothalamic-pituitary axis was normal response in hypoglycemia and negative for anti-insulin antibody. Endocrinological and imaging data eliminated the possibility of insulinoma. His symptoms responded well to the therapy of prednisolone (60 mg/day) and plasmapheresis. We followed up the patient over the subsequent 6 months without remarkable lesions. He has had no further recurrences of hypoglycemia. We believe that the antiinsulin receptor antibody might have induced hypoglycemia in this patient. (C) 2012 Elsevier Ltd. All rights reserved.
