INTRODUCTION There are data suggesting that the diagnostic usefulness of faecal calprotectin (FC) may vary depending on the Crohn's disease (CD) location. The aim of the study was to compare the diagnostic usefulness of FC in CD patients with different disease locations. MATERIAL AND METHODS We prospectively enrolled 120 CD patients in the study. Disease(More)
The aim of the study was to define the relationship between the concentration of PAHs in sewage sludge at a particular location and their amount in various plant materials growing on it. The credibility of the results is enhanced by the fact that sewage sludge from two separate sewage-treatment plants were selected for their influence on the content of PAHs(More)
The aim of the study was to assess the role of magnetic resonance enterography (MRE) in predicting one-year efficacy of anti-tumor necrosis factor antibodies--infliximab (IFX), adalimumab (ADA) in Crohn's disease (CD) patients primarily responding to therapy. We performed retrospective analysis among 61 CD patients who had undergone a successful IFX/ADA(More)
Etiological factors of bone metabolism disorders in inflammatory bowel diseases have been the subject of interest of many researchers. One of the questions often raised is vitamin D deficiency. Calcitriol acts on cells, tissues and organs through a vitamin D receptor. The result of this action is the multi-directional effect of vitamin D. The reasons for(More)
INTRODUCTION Crohn's disease (CD) promotes the development of osteopaenia/osteoporosis, the cytokine background of which is not fully known. AIM Evaluation of bone mineral density (BMD), the prevalence of osteopaenia and osteoporosis, and the determination of the levels of selected interleukins (IL), osteoprotegerin (OPG), and s-RANKL proteins in patients(More)
The study was focused on two goals: (i) the confirmation of the existence of a general relation between the content of polycyclic aromatic hydrocarbons (PAHs) in sewage sludge and in plants growing in it, regardless of the type and content of sewage sludge, and (ii) if so, the answer to the question whether the uptake of PAHs by plants depends on their(More)
INTRODUCTION Fecal calprotectin is a useful diagnostic marker in the assessment of Crohn's disease (CD) activity. However, the clinical picture of CD is diverse and its phenotypes change with disease duration: in the early phase, an inflammatory activity dominates and, with time, an increasing percentage of patients develop strictures and fistulas.

BACKGROUND Diagnosis and monitoring of Crohn's disease (CD) is difficult and time-consuming. In recent years, diagnostic usefulness of fecal calprotectin has been proven. However, data on the utility of other fecal markers are scarce. AIMS To evaluate the usefulness of fecal lactoferrin (FL) in the assessment of CD activity. METHODS The group consisted(More)
Magnetic resonance enterography (MRE) is a useful tool in assessing the transmural and extraintestinal lesions in Crohn’s disease (CD). However, the influence of anti-tumor necrosis factor (anti-TNF) therapy on MRE features of CD severity remains unknown. The purpose of the study was to assess the short- and long-term changes in MRE features of CD activity(More)
Down-regulation of immune-mediated angiogenesis seems to be an important mechanism in anti-tumor necrosis factor α (anti-TNFα) therapy for Crohn's disease (CD). However, it remains to be established whether the baseline pro-angiogenic activity as reflected by the level of vascular endothelial growth factor (VEGF) could be of predictive value for successful(More)
