[Gastroenterologist diagnosting left atrial myxoma in patient with gastroesophageal reflux disease].

The authors presents the clinical case of the left atrial myxoma diagnosed by gastroenterologist in patient with gastroesophageal reflux disease.

[Fecal calprotectin as a biomarker effectiveness of various interventions in patients with inflammatory bowel disease].

Among the chronic diseases of the gastrointestinal tract of the special place occupied by inflammatory bowel disease (IBD), in which the lining of the intestine produces a significant number of neutrophils, which has prompted researchers and clinicians use a protein derived from neutrophils as a biomarker for the assessment of the intestinal wall and the effectiveness of treatment in patients IBD. One of these proteins is calprotectin (CP), which can be considered as a biomarker of activation, destruction and loss of neutrophil cells, to a lesser extent-- the activated monocytes and macrophages. Various studies have shown that the concentration of fecal calprotectin (FCP) correlates well with endoscopic and histological parameters of intestinal inflammation.

[Calprotectin concentration in stool samples as a determinant of the activity degree of inflammatory process in inflammatory bowel diseases].

At IBD in the exacerbation phase was detected the increase of fecal calprotectin (FC) level in 98% of patients. With increasing of clinical disease activity in patients with UC as well as CD was marked a significantly increased content of calprotectin in stool samples, which was accompanied by increase of indicators of inflammation acute phase: rising RRF, leukocytosis, an increase of frequency of stool with blood and mucus, fever and abdominal pain. In the phase of exacerbation the increase in concentration of CRP depends on the degree of inflammatory activity, rather than on lesion localization.

[Analysis of total cost of treatment of patients with inflammatory bowel diseases].

The article stresses that among the chronic diseases of the digestive tract occupy a special place inflammatory bowel disease (IBD)--UC and BC with multiple complications and the onset of early disability of patients. IBD is a serious issue of gastroenterology, since their etiology remains unknown, and specific treatment hasn't yet been developed. Finally, the prevalence and social significance of IBD also occupy a leading place among the diseases of the digestive organs, since they are characterized by recurrent course and have adverse medical and social prognosis.

[Pharmacoeconomic analysis of treatment of certain diseases of the digestive system].

The article provides data of the pharmacoeconomic analysis (cost/effectiveness) of treatment of peptic ulcer, ulcerative colitis, Crohn's disease, gastroesophageal reflux disease, biliary sludge and cholelithiasis. It was shown that the most appropriate treatment scheme is one that characterized by lower costs per unit of effectiveness. Analysis of cost/effectiveness can give an economic assessment of clinical efficacy, compare alternative treatments and help to choose the method by which the efficiency increases faster than the level of costs.
