Plasma Bacterial Metabolites in Crohn's Disease Pathogenesis and Complications.

Background/objectives: Crohn's disease is known for being associated with an abnormal composition of the bacterial flora, dysbiosis and intestinal function disorders. Metabolites produced by gut microbiota play a pivotal role in the pathogenesis of CD, and the presence of unspecific extraintestinal manifestations.

Methods: The aim of this study was a determination of the level of bacterial metabolites in blood plasma in patients with Crohn's disease.

The burden of irritable bowel syndrome and functional dyspepsia in Poland: a cross-sectional study from West Pomeranian Voivodship.

Background: Functional gastrointestinal disorders (FGIDs), now known as disorders of gut-brain interaction (DGBIs), such as Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD), significantly impact global health, reducing quality of life and burdening healthcare systems. This study addresses the epidemiological gap in Poland, focusing on the West Pomeranian Voivodeship.

Methods: We conducted a cross-sectional study of 2070 Caucasian patients (58.

Endoscopic findings in the upper gastrointestinal tract in patients with Crohn's disease are common, highly specific, and associated with chronic gastritis.

Crohn's disease (CD) may affect the entire gastrointestinal tract including its upper part. However, this aspect is poorly addressed in scientific literature and considered a rare finding. Here we aimed to prospectively investigate the prevalence, characteristics and clinical significance of upper gastrointestinal tract involvement in patients with CD, with particular focus on stomach bamboo joint-like appearance (BJA), Helicobacter pylori status and presence of microscopic changes.

Progression risk factors of ulcerative proctitis.

Ulcerative colitis (UC) is an inflammatory bowel disease of unknown etiology. It is characterized by a chronic course with periods of aggravations and remissions. Among patients, 25-55% present with ulcerative proctitis (UP) at the time of diagnosis.

The gastric microbiota in patients with Crohn's disease; a preliminary study.

The gastric microbiota in Crohn's disease (CD) has not been studied. The purpose of the study was to evaluate differences of stomach microbiota between CD patients and controls. DNA was extracted from gastric mucosal and fluid samples, from 24 CD patients and 19 controls.

Cerebral venous sinus thrombosis in a young patient with ulcerative colitis: A case report.

Rationale: Cerebral venous sinus thrombosis (CVST) represents one of the most alarming forms of hemostatic abnormalities that may occur in patients with inflammatory bowel diseases (IBDs).

Patient Concerns: Here we report a case of a 25-year-old male with ulcerative colitis, who developed such thromboembolic complication during flare of the disease. CVST in our patient was clinically manifested by headache and nausea.

Clinical significance of endoscopic findings in the upper gastrointestinal tract in Crohn's disease.

Crohn's disease is an inflammatory disorder that can affect the entire gastrointestinal tract but typically involves the ileocecal region. Before endoscopy was widely used, involvement of the esophagus, stomach, and duodenum was thought to be rare. Recent publications demonstrated that not only are upper gastrointestinal lesions common in Crohn's disease (affecting up to 75% of the patients), but they also present characteristic endoscopic findings with potential clinical significance.

Relationship between the SNPs and Crohn's Disease Susceptibility and Phenotype in the Polish and Bosnian Populations: A Case-Control Study.

It is suggested that IL-23/IL-17 axis and single nucleotide polymorphisms (SNPs) of may have crucial role in pathogenesis of Crohn's disease (CD). Thus, we sought to assess the SNPs contribution to susceptibility and phenotype of CD. We recruited 117 CD subjects and 117 controls from Poland and 30 CD subjects and 30 controls from Bosnia and Herzegovina (B&H).

ABCB1 3435C>T and 2677G>T/A polymorphisms in Polish and Bosnian patients with Crohn's disease - A preliminary report.

The role of ABCB1 single nucleotide polymorphisms (SNPs) in the development of Crohn's disease (CD) remains unclear. Due to inconsistent results of several European population-based studies and limited information on populations from Poland and Bosnia and Herzegovina (B&H), we conducted a preliminary association study of two main ABCB1 SNPs and CD. ABCB1 3435C>T and 2677G>T/A SNPs were analyzed in Polish and Bosnian patients with CD (n = 85 and n = 30, respectively) and controls (n = 82 and n = 30, respectively) using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for 3435C>T and allele-specific PCR for 2677G>A/T SNP.

NOD2/CARD15 mutations in Polish and Bosnian populations with and without Crohn's disease: prevalence and genotype-phenotype analysis.

Data on prevalence and phenotypic consequences of nucleotide-binding oligomerisation domain 2/caspase recruitment domains 15 (NOD2/CARD15) variants in Crohn's disease (CD) population in Poland and Bosnia and Herzegovina (B&H) are nonexistent. We aimed to determine the prevalence of NOD2/CARD15 mutations and their association with disease phenotype in Polish and Bosnian patients with CD and in healthy controls. We prospectively recruited 86 CD patients and 83 controls in Poland and 30 CD patients and 30 controls in B&H, 229 in total.

[Ectopic pancreas mimicking advanced gastric malignancy--case report].

Ectopic pancreas is the most common type of ectopic tissue in gastrointestinal tract. It is typically asymptomatic, presenting as a small submucosal lesion in prepyloric region of stomach. The diagnosis is usually incidental, during gastroscopy.

[Irritable bowel syndrome--irritable bowel or irritable mind?].

Irritable bowel syndrome (IBS) is one of the most common disorders of gastrointestinal tract, affecting significant number of western population. The characteristic features are chronic and(or) recurrent abdominal pain and discomfort associated with changes in the bowel habit with or without bloating. According to Rome Criteria III there is an improved focus on the intestinal transit time which allows for better diagnosis and characterization of patients either with diarrhea, constipation predominant or mixed type IBS.

HFE gene mutations in patients with alcoholic liver disease. A prospective study from northwestern Poland.

Introduction: Hereditary hemochromatosis has been linked with C282Y and H63D mutations of the HFE gene encoding human hemochromatosis protein. It is genetic disorder of iron metabolism, leading to iron accumulation and increased liver fibrosis. The association between alcoholic liver disease (ALD) and HFE gene mutations remains unclear and requires clarification.

Frequency of mutations related to hereditary haemochromatosis in northwestern Poland.

Hereditary haemochromatosis has been linked with C282Y and H63D mutations of the HFE gene. In Europe, frequencies of these mutations are the highest in Northern European countries and gradually decrease southwards. We analysed the prevalence of HFE mutations in 1517 DNA samples, including 1000 samples from the general population (subjects registered at general practitioner practices) in northwestern Poland, and 517 samples of cord blood from the same region.
