    The evaluation of paraoxonase 1 activity in patients with gestational diabetes
    (Acta Medica Mediterranea, 2013) Atay A.E.; Sakar M.N.; Culcu N.S.N.; Simsek H.; Akbas H.; Acar M.; Isik B.
    Material and methods: Sixty five patients with GDM and 66 healthy pregnants were enrolled. Paraoxonase activity, insulin levels, HOMA-IR, demographic features and anthropometric measurements were evaluated. Results: The mean paraoxonase activity was significantly diminished in patients with GDM (p:0,004). Insulin level and HOMA-IR were significantly higher in GDM patients (p:0,004 and p:0,001; respectively). The mean interval between present and previous pregnancy was significantly shorter in patients group (p:0,004). There was a significant correlation between PON1 activity and serum LDL, HDL levels and weight gained during pregnancy (p:0,001,p<0,001 and p:0,002; respectively) but not with weight and parity. However HOMA-IR was significantly correlated with weight and parity (p:0,001 and p:0,002; respectively). Discussion: Diminished PON1 activity and enhanced oxidative stress accompany to insulin resistance in the pathogenesis of GDM. Oxidative stress is associated with weight gained during first 2 trimesters of pregnancy rather than obesity.

    Risk of Helicobacter pylori infection in newborn babies of Helicobacter pylori-positive pregnant women
    (1998) Dursun M.; Goral V.; Simsek H.; Yukselen V.; Hascelik G.; Canoru F.
    Helicobacter pylori (H.pylori) is one of the rare organisms that can maintain its life in acidic condition of stomach. A number of studies indicate that it is closely inked to mainly duodenal ulcer as well as peptic ulcer, non-ulcer dyspepsy, gastric cancer and MALT lymphoma. The aim of our study was to determine whether newborn infants of H.pylori-positive mothers are at risk of H.pylori infection A total of 48 mother and their newborn babies were included in the study. Soon after the birth, blood specimens were taken from both mothers and babies. Anti-H.pylori IgG was examined from the blood of the mothers by ELISA. The blood of babies of mothers with anti- H.pylori IgG-positive was investigated for both anti-H.pylori IgG and anti- H.pylori IgA. In 36 (75.0%) of 48 women included in the study, anti-H.pylori IgG antibody was found as positive. In addition, anti-H.pylori IgG was determined to be positive in 32 (89.0%) of 36 babies whose mothers were positive for anti-H.pylori IgG. These 32 babies whose anti-H.pylori IgG was positive were examined for anti-H.pylori IgA. In 3 babies (9.4%), it was found to be positive (p<0.01). In conclusion, owing to IgG's feature of being able to transmit through the placenta, it is clear that the presence of anti- H.pylori IgG in the serum of babies whose mothers are positive for anti- H.pylori IgG antibody cannot be an indicator of H.pylori infection. Determination of anti-H.pylori IgA antibody as positive is important and statistically significant (p<0.01). According to the results of this study, it can be said that at least the possibility of vertical transmission may exist.
