TNF gene polymorphism as a risk factor that can cause arterial hypertension in patients suffering from gastroesophageal reflux disease

Comorbidity of arterial hypertension (AH) and gastroesophageal reflux disease (GERD) is widely spread (from 20.6 % to 29 %); despite that fact, risk factors that can cause AH in patients suffering from GERD have still not been examined completely. Experts are discussing a role played by anti-inflammation cytokine of tumor necrosis factor alpha (TNFa) both in AH occurrence and GERD pathogenesis as it is its activity that is to a great extent determined by a patient having certain alleles of tumor necrosis factor (TNF) gene. Therefore, it seems vital to study TNF gene G308A polymorphism in patients with combined AH and GERD. Our research goal was to study frequency and variants of TNF gene G308A polymorphism relations with AH risk and AH phenotypic peculiarities in patients suffering from GERD. We examined 58 people who had AH (29 patients with isolated AH, average age being 53 [46; 62], and 29 patients with combined AH and GERD, average age being 56 [51; 59]). Patients from both groups were comparable in terms of sex, age, and examined factors of cardiovascular diseases risks...
