Human leucocyte antigen (HLA) expression is altered in oesophageal carcinomas compared with normal tissue. It is unclear, however, whether this phenotype precedes malignant transformation or results as a consequence of it.
The purpose of research - to study the features of circadian profile of blood pressure (BP), the data of echocardiography, pH-monitoring, lipid spectrum, level of apelin and the state of the system "lipid peroxidation-antioxidant protection" in patients with a combination of arterial hypertension (AH) and gastroesophageal reflux disease (GERD) depending on the level of AH. It was examined 126 patients with combination of AH II stage, 2-3 degrees, and GERD, 70 (55.56%) men and 56 (44.44%) women, mean age 56.84 ± 1.17. The anthropometric indicators, a condition of "lipid peroxidation- antioxidant protection", the level of apelin, ambulatory blood pressure monitoring (ABPM), echocardiography, esophageal pH-monitoring were evaluated. Analysis of the results was performed using a computer program IBM SPSS Statistics 21.0 for Windows XP. According to the daily averages ABPM systolic BP/diastolic BP in the I group were 141.2 ± 0.8/90.4 ± 0.4 mm Hg., in II group - 163.3 ± 0.9/101.0 ± 0.5 mm Hg., in III group - 185.6 ± 0.8/112.1 ± 0.5 mm Hg., p = 0.001. There are only 25.39% of patients had normal indicators of the variability of BP among individuals with comorbidity. Transformation from mild AH to moderate was accompanied by a significant increase in the severity of left ventricular remodeling by type of concentric hypertrophy. The data of esophageal pH-monitoring allow us to classify the disorders as severe gastroesophageal reflux in patients with a combination of AH and GERD (DeMeester, 1993). In the group with first degree of AH the average rate of circulating apelin was 930.58 ± 56.27 pg/mL, for the patients with 2nd degree of AH - 880.56 ± 17.97 pg/ml, p>0.05, in patients with third degree of AH - 650.91 ± 12.87 pg/ml (p = 0.001). Assessment of lipid profile has allowed to establish the worse dyslipidemia in patients with 3rd degree of AH combined with GERD (atherogenic ratio - 3.11 ± 0.09). The deterioration of degree of AH combined with GERD accompanied by an increase of oxidative stress with increase of nitrites plasma and malondialdehyde concentration, and decrease of glutathione peroxidase and of SH-groups concentration. Increased degree of AH in patients with severe GERD accompanied by worsening of left ventricular remodeling, reduction of apelin levels, progression of dyslipidemia, and imbalances in the system of "lipid peroxidation-antioxidant protection."
