The aim of the study. To determine the frequency and character of syntropic extrahepatic lesions in cirrhotic patients depending on the hepatopulmonary syndrome severity degree.

Materials and methods. In a randomized manner with preliminary stratification by the presence of hepatopulmonary syndrome were studied 93 patients with liver cirrhosis, who underwent the comprehensive clinical-laboratory and instrumental examination.

Results. According to the obtained results, most often in patients with liver cirrhosis associated with hepatopulmonary syndrome syntropic extrahepatic lesions affected other organ systems as follows: digestive system - 100.0 % patients under investigation; hematopoietic system - 84.9 %; nervous system - 81.7 %; integumentary system and mucous membranes - 78.5 %; blood circulatory system - 76. 3 %; osteoarticular system - 67.7 %; urinary system - 22.6 %. Increased severity of hepatopulmonary syndrome significantly (p < 0.05) correlated with thein creased frequency of lesions.

Among syntropic polymorbid lesions of the integumentary system and mucous membranes, 68.8 % patients with hepatopulmonary syndrome had jaundice, 66.7 % - telangiectasia. Among lesions of the osteoarticular system osteopenia was diagnosed in 44.7 % of patients, osteoporosis - in 27.7 %. Among lesions of the circulatory system 52.7% of patients suffered from heart rhythm disorders, 49.5 % - from arterial hypotension, 20.4 % - from cirrhotic cardiomyopathy. Among lesions of the hematopoietic system anemia (76.3 %), coagulopathy (73.1 %) and thrombocytopenia (61.3 %) were diagnosed most often. Digestive system lesionsinclude esophageal veins varicosities (94.6 % of patients), hemorrhoidal veins varicosites (68.8 %), and cirrhotic gastropathy (62.4 %). Among lesions of the urinary systemin 21.5 % of patientswas diagnosed type II hepatorenal syndrome. Among the lesions of central nervous system in 81.7 % of patientswas diagnosed hepatic encephalopathy. The frequency of syndromes and nosological units increased significantly (p < 0.05) with the increase of hepatopulmonary syndrome severity.

Conclusions. 100.0 % patients with liver cirrhosis accompanied byhepatopulmonary syndromewere affected by syntropic polymorbid lesionsof the digestive system, 94.6 % of which were represented by esophageal vein varicosites. Out of 84.9 % of patients with hematopoietic lesions anemia was diagnosed in 76.3 %, coagulopathy - in 73.1 % of cases. Of total 81.7 % patients withnervous system injurieshepatic encephalopathy was diagnosed in 81.7 % patients. In 78.5 % cases of damaged skin, its appendages and mucous membranesjaundice covered 68.8 %, and telangiectasia 66.7 % of cases. In 76.3 % of cardiovascular system lesions arrhythmias were diagnosed in 52.7 %. With the increasing severity of hepatopulmonary syndrome, the frequency of the above lesions increased significantly (p < 0.05).

Introduction. Evaluating acid-reducing medications through their effect on various gastric juice parameters in peptic ulcer patients provides deeper insight into the complex mechanism of gastric secretion, which includes acidity levels, pepsin, electrolytes, bicarbonates, and mucus.

The aim of the study. To determine the prognostic value of gastric secretion parameters and their constellations for predicting parietal cell response to submaximal pentagastrin stimulation and the blocking effect of famotidine in patients with gastric and duodenal peptic ulcer disease.

Materials and methods. The study included 40 randomized Helicobacter pylori-positive patients (28 women, 12 men, aged 18-68) with endoscopically confirmed duodenal ulcer disease in the acute phase. Modified fractional probing was used to assess changes in gastric secretion.

Results. H⁺ debit in basal secretion showed a significant direct correlation with multiple parameters. Different acid responses to stimulation were associated with specific baseline parameter constellations. Weak response to H₂-blocker was confirmed in patients with hyperacidity after stimulation, combined with elevated HCl and increased total acidity in basal secretion. A strong response to H₂-blocker was confirmed in several parameter constellations, with the best predictive constellation (p < 0.01) including elevated N-acetylneuraminic acid, normal K⁺, normal pepsin debit, normal pepsin, and elevated Na⁺ in basal secretion.

Conclusions. The prognostic value of gastric secretion parameters and their constellations allows tailoring blocker dosage: higher doses for patients predicted to have a weak response and lower doses for those predicted to have a strong response to stimulation.
