[The role of cytokines in pathogenesis of nonspecific ulcerative colitis].

Etiology of nonspecific ulcerous colitis (NSUC) as well as its pathogenetic mechanisms remain obscure. Cytokines are presently shown to play an essential role in development of inflammation. Cytokines are produced by the cells in the inflammatory infiltrate in NSUC, therefore, changes of their level in the blood and biopsies from colon mucosa is naturally determined. Current investigations register various changes in the levels of both proinflammatory and antiinflammatory cytokines. Further studies of unknown mechanisms of cytokines action may contribute to design of new methods of NSUC management.

[Interferon status of patients with non-specific ulcerous colitis and its correction with interferon inducers].

AIM: To examine validity of using interferon inductors (amixin and cycloferon) in combined treatment of patients with non-specific ulcerous colitis (NUC). MATERIAL AND METHODS: 113 NUC patients received basic antiinflammatory therapy (glucocorticoids and preparations of 5-aminosalycylic acid). Patients of groups 1 and 2 received interferon inductors (amixin and cycloferon in tables), respectively. Patients of groups 1a and 2a received placebo. All the patients were examined clinically with evaluation of interferon status and cellular immunity before and after the treatment. Colon mucosa biopsies obtained endoscopically were studied histologically. RESULTS: Alpha- and gamma-interferon production by leukocytes was substantially suppressed in all the examinees against normal levels of serum and spontaneous interferon. The interferon inductors stimulated relief of clinical symptoms and eliminated endoscopic signs of the disease. Amixin and cycloferon normalized interferon status in 36.3 and 33.3% of the treated patients, respectively. No response was registered in 9.1 and 8.4%, respectively. Improvement was seen in 54.6 and 58.3%, respectively. CONCLUSION: Cycloferon and amixin, interferon inductors, are effective in the treatment of NUC.

[Chronotherapy approaches in the treatment of gastroduodenal ulcer].

Each patient with ulcer has his/her own 24-h biorhythm of acid production, features of food alkalization, duration of duodenogastric and gastroesophageal reflux. Pharmacological test conducted in prolonged 24-h pH-metry helps to select the most effective antisecretory drug, while analysis of 24-h biorhythm of acid production--optimal time for drug intake and number of its daily doses.

[The response to combined therapy of hepatic encephalopathy in patients with hepatic cirrhosis].

Combined therapy with gepa-merz (L-ornitine-L-aspartate) and lactulose (a synthetic disaccharide) was given to 40 patients with hepatic encephalopathy and toxic hepatic cirrhosis in decompensation. Combination of gepa-merz with lactulose was effective in the above patients. Moreover, it is an optimal one as it has a double impact on ammonia toxicity which is a basic neurotoxin in pathogenesis of hepatic encephalopathy.

[Clinico-functional evaluation of the efficacy of treating gastroesophageal reflux disease combined with bronchial asthma with omeprazole].

AIM: To investigate the prevalence of gastroesophageal reflux disease (GERD) among patients with bronchial asthma (BA) and to determine the effects of omeprazole therapy on the outcome of asthma in patients with GERD. MATERIAL AND METHODS: 117 BA patients were examined. Those who had a concomitant GERD were divided into two groups to receive outpatiently omeprazole 40 mg/day or placebo for 8 weeks. Spirometry was performed before and after the treatment. Clinical indices were calculated by daily summarizing of pulmonary (CIEI I) and gastric (CIEI II) symptoms improvement. RESULTS: The trial showed a significant correlation between CIEI I and CIEI II (r = 0.574, p < 0.001) during 8-week omeprazole therapy. The analysis of PEV and FEV1 dynamics showed a significant improvement (p < 0.05) of bronchial conduction in BA patients receiving omeprazole vs placebo. CONCLUSION: A significant correlation exists between the severity of gastroesophageal refluxes and bronchoobstructive syndrome in BA and GERD patients. Omeprazole treatment of such patients relieves BA and GERD symptoms.

[Efficiency of quamatel in combination with device sound stimulation of the gastroduodenal zone in ulcer patients].

24-hour monitoring of gastric juice pH and esophagogastroduodenoscopy with biopsy and test for H. pylori (HP) were conducted in 117 patients with ulcer before and after treatment with famotidine (quamatel, Hungary) and device sound stimulation (DSS). Combined eradication therapy (quamatel 40 mg/day, metronidazole 500 mg 4 times a day, amoxicilline 750 mg 3 times a day, DSS) eradicated HP in 100% of patients with gastric ulcer and 91.7% of patients with duodenal ulcer. Scarring of the ulcer defect occurred for 11.8 +/- 1.1 and 15.3 +/- 1.4 days, respectively. These results are better than those of monotherapy with quamatel or DSS.

[Use of ednit in the treatment of portal hypertension in patients with chronic hepatitis and liver cirrhosis].

AIM: To study ednit (ACE inhibitor) effectiveness in the treatment of portal hypertension in patients with chronic hepatitis (CH) and hepatic cirrhosis (HC). MATERIAL AND METHODS: The examination of 87 patients with active CH and 54 patients with HC at the preascytic stage included two-dimentional ultrasonic scanning of the abdominal organs with doppler fluometry of the vessels in the territory of the portal vein, tetrapolar rheohepatography, ultrasound investigation, angiography of the abdominal vessels. The patients received combined therapy with ednit in a dose 5 mg twice a day for at least 5 weeks. RESULTS: Patients with active CH and HC having portal hypertension treated with adjuvant ednit in the above dose achieved marked clinicobiochemical remission quicker, portal-hepatic circulation improved. CONCLUSION: The addition of ednit to therapy of active CH and HC with portal hypertension is effective as it lowers total peripheral vascular resistance which eventually results in a fall of pressure in the territory of the portal vein and improvement of hepatic circulation. The highest effect is reached in administration of 5 mg twice for 24 hours.

[24-hour monitoring of gastric juice pH in assessment of anti-ulcer treatment].

AIM: Comparison of various schemes of three-component eradication of duodenal ulcer (DU) using 24-h monitoring of gastric juice pH. MATERIALS AND METHODS: 62 DU patients in aggravation period have undergone 24-h monitoring of gastric juice pH and esophagogastroduodenoscopy with biopsy and H.pylori test of the treatment beginning and end. Patients of group 1 (n = 28) received ranitidin, metronidazole and amoxicillin while patients of group 2 (n = 34) took quamatel, metronidazole and amoxicillin. RESULTS: 24-h monitoring of pH of the gastric juice demonstrated that three-component therapy consisting of quamatel (20 mg/day, metronidazole (500 mg 4 times a day), amoxicillin (750 mg 3 times a day) maintains the level of intragastric acidity optimal for quick scarring of duodenal ulcer defect and led to eradication of H.pylori in 91.2% of cases. CONCLUSION: 24-h monitoring of gastric juice pH is a significant method of assessment of antiulcer treatment efficacy.

[Josamycin combination with ranitidine in therapy of gastroduodenal ulcer: clinical efficiency].

Efficacy of a novel eradication treatment with ranitidine, trichopol and jozamycin was compared to that of the standard three-component therapy and monotherapy with ranitidine in 76 patients with exacerbation of gastric and duodenal ulcer. Therapeutic monitoring of ranitidine was performed. In relation to healing of ulcer defect and eradication of Helicobacter pylori, jozamycin is not less effective and more safe than standard three-component therapy. Interaction of the scheme components increases plasma concentration of ranitidine especially in patients with concomitant hepatic and renal diseases.

[Motor and secretion function of stomach and duodenum, duodenogastric reflux in patients with duodenal ulcer].

Gastric secretion, motor function and tonicity of the stomach and duodenum, duodenogastric reflux were studied in inpatients with two clinicopathogenetic types of duodenal ulcer: observed at young age (type 1) and in later life (type 2). The examination included pH-metry with simultaneous balloon cimography, chromogastroduodenoscopy with Kongo-red, tests for Helicobacter pylori conducted on the biopsy samples. All the patients were found to have continuous acid production. High acid production was more frequently registered in males with the disease type 1, the lowest production was in females with the disease type 2. Duration of the acid inflow into the duodenum in patients with the disease type 2 was greater than that in young subjects. Mild ulcer was associated with moderate acidity in the duodenum, in severe ulcer the acidity was very high. Males with the disease 1 and 2 and females with type 2 had hyperkinetic, hypertonic gastric motor function. In duodenal ulcer prevalent is hypertonic, hyperkinetic type of duodenal motor function being most frequent among males with the disease type 2. Duodenogastric reflux occurs more often in patients with intensive acid production associated with hypotonic, hypokinetic motor type and duodenal tone.

[Clinical features of gastrointestinal diseases in patients with primary mitral prolapse].

Whether patients with mitral prolapse (MP) have specific features in the course of their gastrointestinal diseases (GD) was studied in 420 MP patients with various GD. Echocardiography and examination of the vegetative status were conducted in all the patients. On demand, esophagogastroduodenoscopy, ultrasonic investigation of the abdominal organs, multistage fraction duodenal intubation were made. The findings evidence of more severe course of GD in MP patients. This manifests in early onset, severe pain and dispeptic syndromes, marked mucosal inflammation and is explained by dysfunction of the vegetative nervous system and generalized dysplasia of the connective tissue.
