Objectives: The aim of this study was to elucidate the role of dopamine receptor D2 / ankyrin repeat and protein kinase domain containing 1 (DRD2/ANKK1) TaqIA allelic polymorphism in the HPVinduced cervical carcinogenesis. Methods: 1. Effect on the risk of cervical precancer: After an 8year followup, out of 214 women with persisting highrisk HPV infection, 102 developed highgrade cervical dysplasia or cervical intraepithelial neoplasia (CIN) grade III, while 112 did not. The subjects were genotyped for the DRD2/ANKK1 TaqIA polymorphism by PCRRFLP, and the allelic distributions were compared between groups with and without highgrade dysplasia. 2. Prognostic value: Two hundred and thirty nine women with cervical precancer/cancer were followed for 5 years. Complete remission was achieved at 182 women. To assess the prognostic value of the TaqIA polymorphism, genotype frequencies were compared between patients reaching and not reaching complete remission. Results: The frequency of A1/A1+A1/A2 genotypes was higher among women who developed highgrade cervical dysplasia (OR: 1.87, 95% CI: 1.053.33; p=0.034) than in the other group. Occurrence of the A1 allele was more frequent among women who did not reach complete remission (OR: 2.00, 95% CI: 1.073.74; p=0.030) than in women with complete remission. Conclusions: This is the first report on the possible involvement of DRD2/ANKK1 TaqIA polymorphism in cervical carcinogenesis. The A1 allele seems to increase the risk of cervical precancer, and it may also be associated with a worse prognosis in women with HPVinduced cervical cancer. The results need further validation in largescale molecular epidemiological studies., József Cseh, Zsuzsa Orsós, Emese Pázsit, Erika Marek, András Huszár, István Ember, István Kiss, and Literatura
The condition of the protective barrier of the stomach in patients with duodenal ulcer associated and non-associated with H. pylori infection has been studied. The state of gastric mucosal barrier was studied in 72 patients with peptic ulcer disease association with H. pylori and 26 patients without H. pylori by determining the content of insoluble glycoproteins and its fractions in the basal portion of the gastric juice. In a comparative perspective the state of these indicators were studied depending on the association with H. pylori and the severity of the disease. In patients with H. pylori, damages of protective mucus barrier are characterized by the significant shortage of fucose, which is considered to be the main component of the insoluble glycoproteins. In patients without H. pylori, status of mucosal barrier is characterized by uniform and less significant reduction in the content of fractions of insoluble glycoproteins. In this patients the reduction of insoluble glycoproteins is not dependent on the frequency of exacerbation. The content of fucose in the mucous gel of gastric juice is a diagnostic criterion for determining the frequency of recurrence of the disease in patients with H. pylori infection., Abdujalol Vahabovich Yakubov, Nargiza Ihsanovna Pulatova, and Literatura
