Utility of Point Shear-wave Elastography to Assess for Hepatic & Pancreatic Fibrosis in Pediatric...
Cystic FibrosisCystic Fibrosis Liver Disease1 moreDiagnosis of hepatic fibrosis is challenging as specific tests for detection of fibrosis in pediatric Cystic Fibrosis associated liver disease (CFALD) have not been developed and existing investigations do not correlate well with presence or severity of disease. Using a Liver biopsy it is difficult to diagnose this condition because of the patchy nature of the disease. Investigators intend to identify hepatic and pancreatic fibrosis in Cystic Fibrosis patients using Elastography and correlate this with their biochemical markers as well as histological findings of patients who have undergone liver biopsy for diagnosis of CFALD.
MRI to Characterize and Predict CF Liver Disease in PUSH Cohort
Cystic Fibrosis Liver DiseasePancreatic InsufficiencySpecific Aim 1. Determine if valid results of non-sedated MRI based assessments of liver stiffness and lipid content can be obtained in more than 90% of children and young adults with cystic fibrosis. Specific Aim 2. Determine hepatic lipid content using the HepaFat sequence and liver stiffness using MRE. Investigators will compare the results obtained by MRI with PUSH study grayscale ultrasounds in CF patients with normal, heterogeneous, homogeneous or nodular (cirrhotic) pattern on ultrasound. Specific Aim 3. Creation of an imaging core lab to centralize evaluation of MR imaging data, allow for remote image upload, electronic data storage, and remote image viewing/interpretation. This infrastructure will be utilized to standardize image post processing. Specific Aim 4. Using the longitudinal PUSH study, determine if MRI based imaging improves discrimination of subjects at risk for progression to advanced CF liver disease (development of cirrhosis) compared to using US imaging alone
Intestinal Microbiota Composition in Patients With Chronic Pancreatitis and Pancreatic Exocrine...
Chronic PancreatitisPancreatic Exocrine InsufficiencyAssessment of qualitative and quantitative composition of the intestinal microbiota in patients with CP; in patients with CP and PEI complication of mild to severe degree; patients with CP and PEI who underwent surgical intervention on the pancreas. Intergroup comparison of the microbial compositional characteristics and their analysis. Correction of enzyme replacement therapy in selected groups of patients with regard to the identified microbial characteristics. Assessment of the intestinal microbiota composition in dynamics after 6 (+1) months on the background of allocated therapy
Pancreatic Cancer Malnutrition and Pancreatic Exocrine Insufficiency in the Course of Chemotherapy...
Pancreatic CancerExocrine Pancreatic Insufficiency4 moreMalnutrition and cachexia are common in patients with advanced pancreatic ductal adenocarcinoma (PDAC) and have a significant influence on the tolerance and response to treatments. If timely identified, malnourished PDAC patients could be treated to increase their capacity to complete the planned treatments and therefore, possibly, improve their efficacy. The aim of the study is to assess the impact of nutritional status, pancreatic exocrine insufficiency (PEI), and other clinical factors on patient outcomes in patients with advanced PDAC. The nutritional status will be determined by means of Mini-Nutritional Assessment score and laboratory blood tests. PEI will be defined as the presence of typical symptoms and/or reduced fecal elastase. Analysis: chemotherapy dosing over the first 12 weeks of therapy (i.e. percent of chemotherapy received in the first 12 weeks, as defined above) PAC-MAIN will provide insights on the role of malnutrition and PEI in outcomes of PDAC.
Pancreatic Exocrine Insufficiency After Bariatric Surgery
ObesityMorbid1 moreMain proposed benefit of sleeve gastrectomy is loss of ghrelin secreting tissue. Some studies express that ghrelin augment pancreatic regeneration. Therefore we hypothesized that with sleeve gastrectomy it may result with pancreatic insufficiency.
