Inflammatory bowel disease (IBD) is a chronic condition affecting primarily the gastrointestinal tract and characterized by growing incidence worldwide. Complex diagnostic process of IBD as well as evaluation of disease activity and intestinal complications that are crucial for the therapeutic decisions, require repetitive, invasive, expensive, time-consuming and poorly tolerated tests. In contrast to endoscopy and computed tomography, ultrasound elastography (UE) is non-invasive, non-radiating and non-contrasting dependent tool which might be utilized in IBD patients for the assessment of the intestinal changes. Therefore, we performed the systematic review to evaluate the possible application of the ultrasound elastography for assessment of the intestinal changes in IBD. After the search of three databases: PubMed, World of Knowledge and Scopus, we identified 12 papers which were included in the final analysis. The majority of the studies were focused on the evaluation of the symptomatic ileal/ileocolonic strictures in Crohn’s disease patients that required surgical resection. Only one study concerned ulcerative colitis. The authors evaluated different UE techniques: strain elastography (SE), acoustic radiation force impulse (ARFI) and shear wave elastography (SWE). Results were expressed with semi-quantitative color mapping and strain measurement. Histological scores of inflammation and fibrosis in Crohn’s disease were used as a reference test in the majority of studies. Ultrasound elastography seems to be a promising novel imaging technique supporting evaluation of the intestinal strictures in Crohn’s disease patients in respect to fibrosis detection as well as differentiation between fibrosis and inflammation. However, further research is needed to establish the position of ultrasound elastography in IBD management.

Background. Non-alcoholic fatty liver disease (NAFLD) is becoming the most common cause of chronic liver disease worldwide, affecting up to 30% of population. Non-alcoholic fatty liver disease can lead to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and hepatocellular carcinoma. Age, obesity, insulin resistance, type 2 diabetes, and dyslipidemia are important risk factors for developing hepatic steatosis. Concomitant diseases, especially cardiovascular, are discussed as important causes of death in NAFLD patients.Objectives. The objective of this study was to conduct a retrospective comparison of the frequency of concomitant diseases in NAFLD patients and controls, especially metabolic syndrome and cardiovascular disease (CVD). Material and methods.A total of 1,058 (558 NAFLD patients and 500 controls). Diagnosis of NAFLD was established with ultrasound examination in the absence of other causes of fatty liver. The control group included patients with no history of liver disease, normal liver image in ultrasound examination and normal liver laboratory tests.Results. Overweight and/or obesity were diagnosed in 80.8% of patients in the study group and 40.8% in the controls (p < 0.001). Metabolic syndrome was present in 48.7% patients in the study group compared with 14.4% controls, (p < 0.001). In the study group, we found higher prevalence of hypertension (56. 1% vs 37%; p < 0.001), type 2 diabetes mellitus (24.4% vs 8.6%; p < 0.001), decreased concentration of serum HDL (35. 1% vs 19.5%; p < 0.001), elevated serum triglycerides (36.5% vs 15.4%; p < 0.001). Cardiovascular disease was found in 13.6% of individuals in the study group and in 15% controls (NS, p = 0.32). The most frequent concomitant gastrointestinal disease present in the study group was gastroesophageal reflux disease (GERD) (31.9% vs 22.8%; p < 0.001) followed by colonic diverticulosis (23.7% vs 15.8%; p < 0.005).Conclusions. Metabolic syndrome with its components is more common in NAFLD patients compared to matched controls. Additionally, NAFLD patients are more often affected by GERD and colonic diverticulosis but not by CVD.

Inflammatory bowel diseases (IBD) are chronic and relapsing disorders usually requiring numerous medical imaging. IBD patients might be exposed to a large dose of radiation. As a cumulative effective dose (CED) ≥ 50 mSv is considered significant for stochastic risks of cancer, it is important to monitor the radiation exposure of IBD patients. In the present work, we aimed to quantify the mean CED in IBD patients and identify factors associated with exposure to high doses of diagnostic radiation. A retrospective chart view of patients with IBD hospitalized between 2015 and 2019 was performed. A total of 65 patients with Crohn’s disease (CD) and 98 patients with ulcerative colitis (UC) were selected. Of all imaging studies performed, 73% were with doses of ionizing radiation. Mean CED (SD) amounted to 19.20 (15.64) millisieverts (mSv) and 6.66 (12.39) mSv, respectively, in patients with CD and UC (p < 0.00001). Only 1.84% of the patients received CED ≥ 50 mSv. We identified three factors associated with CED in the IBD patients: number of surgical procedures, and number and length of hospitalization. CD patients with strictures or penetrating disease and UC patients with extensive colitis were more likely to receive higher radiation doses.
