Introduction: The pathogenesis of functional dyspepsia is complex and not well understood. Therefore, in this disease there should be considered involvement of different pathogenic factors, including intestinal bacteria.Aim: To evaluate the results of the hydrogen breath test in relation to the clinical picture of functional dyspepsia.Material and methods: The study included 40 healthy subjects (group I), 72 patients with postprandial distress syndrome (PDS, group II), and 84 patients with epigastric pain syndrome (EPS, group III). The diagnosis of functional dyspepsia was based on Rome Criteria IV. The urea breath test (13C-UBT) and lactulose hydrogen breath test (LHBT) were performed in all subjects. Patients with a positive urea breath test were excluded from the study. Patients with a positive LHBT test were assigned to antibiotic therapy (1200 mg daily for 14 days). Before treatment and 6 weeks after the end of antibiotic therapy the LHBT was performed, and severity of dyspeptic symptoms was assessed using a 10-points visual analogue scale.Results: A positive LHBT test was found in 35 (48.6%) patients in the group with PDS, and in 40 (47.6%) patients with EPS (p > 0.05). A positive correlation between the results of the LHBT test and severity of dyspeptic symptoms was found in both group (p < 0.001). After treatment with rifaximin the mean LHBT result and the index of severity of dyspeptic complaints were significantly decreased (p < 0.001).Conclusions: Quantitative and/or qualitative changes in the gut microbiota may be the cause of functional dyspepsia.

Background Dyspeptic syndrome is particularly common in postmenopausal women in the form of epigastric pain. The aim of the study was to assess the role of melatonin in chronic dyspepsia in this group of women, and examine the role of Helicobacter infection. Methods The study comprised 152 subjects including 30 healthy women (Group I), 60 women with asymptomatic H.pylori infection (Group II), and 64 women with H. pylori infection with chronic dyspepsia (Group III). Endoscopic examination was performed, as well as histological assessment of gastric end duodenal mucosa, urease breath test (UBT-13C), and immunoenzymatic assessment of serum 17-β-estradiol, follicle stimulating hormone and melatonin, and urinary 6-sulfatoxymelatonin. In Group III, 14-day antibacterial treatment was introduced with pantoprazole, amoxicillin and levofloxacin followed a six-month treatment with placebo in 32 women (Group IIIa), and melatonin 1 mg/morning and 3 mg/at bedtime in the other 32 women (Group IIIb). Results No significant differences were found between serum level of female hormone. Serum melatonin levels were similar between Group I (12.5 ± 2.72 pg/ml) and Group II (10.5 ± 3.73 pg/ml; p > 0,05). The level was significantly lower in Group III (5.72 ± 1.42 pg/ml; p < 0.001). Eradication of H.pylori was obtained in 75.0% women in Group IIIa, and in 84.3% in Group IIIb (p > 0.05). After six months, dyspeptic symptoms resolved in 43.7% patients in Group IIIa and 84.3% in Group IIIb (p < 0.001). Conclusion Melatonin supplementation is useful in treating H. pylori-associated dyspepsia, particularly in postmenopausal women with lower levels of this hormone.

The clinical picture and risk factors are decisive in differential diagnosis. It was proved that patients with metabolic syndrome have increased incidence of malignant tumours. The visceral adipose tissue releases active proteins that promote oncogenesis. We are presenting a case of 34-year-old male with metabolic syndrome suffering from pain in left iliac fossa with accompanying variable stool pattern. At first, the sigmoid diverticulosis was suspected. Patient's condition after the treatment has improved. The ambulatory, partial colonoscopy revealed a cauliflower-like, balloting, wide-base growth in the sigmoid that narrowed its lumen. The biopsy did not reveal atypical growth characteristics. Because of tumour type and enlarged regional lymph nodes seen in abdomen CT scan, the segmental colon resection and end-to-end anastomosis was performed in the area of sigmoid-rectal junction. Macroscopically, there were no visible metastases in the operation field. The surgery and postoperative period ran without any complications. On histopathological examination, the removed tumour was a well differentiated liposarcoma (WDL) stemming unusually from adipose tissue of colonic submucosa in an obese male. WDL is a hard to diagnose tumour, especially in early stages of its growth. In the presented case, the tumour was completely resected.

Superior mesenteric artery syndrome (SMAS) is a rare disease caused by the acute angle of branching of the superior mesenteric artery from the aorta. Material and methods. There were 63 patients (56 women and 7 men) with low body weight, who reported recurrent persistent abdominal pain, nausea, post-prandial vomiting, significant weight loss. All of them had abdominal ultrasonography performed with measurement of the angle of branching of SMA from the aorta. CBC, total bilirubin, AST, ALT, GT, ALP, amylase, lipase, albumins, iron, sodium, potassium, GFR, lipid profile, TSH, urinalysis were ordered. Additionally, esophagogastroduodenoscopy with Hp. test and esophageal impedance measurement in correlation with the reported ailments was performed. Results. Acid reflux impedance was diagnosed in 10 patients. There were >55 acid reflux episodes per day and a positive reflux sign (SI) for heartburn and nausea. Abnormal impedance recording of acid reflux was diagnosed in 17 patients. They had >21 episodes of non-acid reflux per day. Positive reflux sign (SI) was not confirmed for any non-acid reflux-related symptoms. Conclusions. It is justified to perform impedance pH monitoring in this group of patients as it allows to modify the therapy. The most important dietary recommendations are weight gain and understanding the cause of the disease.
