Active clinical trials for "Pancreatitis, Chronic"

This investigation develops an online, patient self-assessment system, called "CarePrep" to support the care and clinical research of patients with chronic pancreatic disease and chronic pancreatic pain. This web-based assessment presents patients with questions that address medical, psychological, social, behavioral, and quality-of-life issues that are relevant to pancreatic disease. Patients will be given the opportunity to enter and track their symptoms over the Internet from home or clinic. The system is also designed to gather clues to identify neuropathic pain, which occurs when the nervous system fails to properly regulate pain signals. Any of these factors can contribute to chronic pain and may point the way to more effective treatment. The broad objective of this study is to extend CarePrep to cover a full range of topics that are relevant to chronic pancreatic disease. The study team will refine this content based on the system's accuracy in real clinical settings and direct efforts to maximize its feasibility.

Clinical course of chronic pancreatitis is still unpredictable, due to the lack of clinical classification. There is no model to assess disease severity or progression or predict patient outcomes. So we need to validate an objective predictive model - Chronic Pancreatitis Prognosis Score (COPPS) for classification, prognostication and management in Chronic Pancreatitis (CP)

Pancreatoduodenectomy carries high morbidity rates even in high-volume centers. Postoperative complications often preclude or delay adequate oral nutrition and nutritional support may be required. However, the role of perioperative nutritional supplementation in well-nourished patients remains controversial. The purpose of this study is to compare the influence of early enteral and oral nutrition on postoperative course and complications after pancreatoduodenectomy. 96 patients undergoing pancreatoduodenectomy will be randomized to receive early enteral nutrition (EN group) or early oral nutrition (PerOs group). The EN group will receive standard enteral diet administered through a nasojejunal tube. Enteral nutrition will be started on the 1st postoperative day and increased daily by 20-40 ml up to the estimated level. The PerOs group will receive oral diets beginning from the 2nd postoperative day and oral intake will be advanced as tolerated.

The phenomenon that oral glucose elicits a higher insulin response than does intravenous (iv) glucose, even at identical plasma glucose (PG) profiles (isoglycemia), is called the incretin effect. In type 2 diabetes mellitus (T2DM) the incretin effect has been shown to be markedly reduced or even abolished. It is not known whether the reduced incretin effect in T2DM is a primary event leading to T2DM or if it is merely a consequence of the diabetic state. To answer this question the investigators plan to estimate the incretin effect in 8 patients with secondary diabetes mellitus (DM) to chronic pancreatitis (CP) and compare it to the incretin effect of 8 patients with CP and normal glucose tolerance (NGT). Eight patients with T2DM and 8 healthy control subjects are studied for comparison. The incretin effect is measured by a 50-g oral glucose tolerance test and an isoglycemic intravenous glucose infusion.

To prospectively define the natural history and the clinical, laboratory and histomorphometric features of chronic pancreatitis (CP) of varying etiology. To identify clinical and laboratory parameters that correlate with the pathophysiologic state in patients with CP. To quantify the behavioral abnormalities associated with CP. To determine psychological and behavioral correlates of CP disease progression and outcomes.

The aim of the study is to assess the accuracy of real-time perfusion imaging pattern of pancreatic focal lesions visualized by contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) for the differential diagnosis between chronic pseudotumoral pancreatitis and pancreatic cancer in a prospective multicenter design. The study will include patients with focal pancreatic masses evaluated by CEH-EUS and EUS-FNA. The diagnosis is usually unknown in the moment of the initial evaluation, the patients being included based on a suspicion of focal pancreatic masses after transabdominal ultrasound, CT or MR examinations. However, after a complete evaluation, a final diagnosis will be reached based on the combination of EUS-FNA cytology/pathology, surgical pathology and minimum 12 months follow-up.

Treatment strategy of chronic pancreatitis (CP) patients with large pancreatic radiolucent stone (≥ 5mm) has not been established. We aimed to figure out clinical features and efficacy of endotherapy for large pancreatic radiolucent stone.

The investigators will enroll a total of 628 patients under 18 years of age with ARP or CP. Included in the total are the 357patients in the INSPPIRE 1 database who are planned to be reenrolled under this protocol over the next 4 years. Patient questionnaires and physician surveys will be applied at the time of enrollment and annually thereafter as long as possible. At the first study visit after turning 18 years of age, the patient will sign the informed consent to continue in the study. Specifically, the investigators will define the demographics of the pediatric ARP and CP cohort, describe risk factors, presence of family history of acute and chronic pancreatitis, diabetes and pancreatic cancer and assess disease burden and sequelae.

The aim of the study is to compare the safety and efficacy of the basket catheter with that of the balloon catheter for endoscopic extraction of pancreatic stones.

The purpose of this study is to define the prevalence of low bone density (osteopenia/osteoporosis) in patients with chronic pancreatitis. Secondary aims include investigating the prevalence of hypogonadism (low sex hormones) in patients with chronic pancreatitis and determining if hypogonadism and/or use of narcotic pain medications are risk factors for low bone density in this patient population. Hypothesis: Patients with chronic pancreatitis are at increased risk of low bone density (osteopenia/osteoporosis), and hypogonadism (low sex hormone levels) and narcotic pain medication use are independent risk factors for the development of low bone density in this patient population. The outcome measures include: i) Prevalence of low bone density (osteopenia/osteoporosis) in patients with chronic pancreatitis (as determined by DXA scan and fracture history). ii) Prevalence of hypogonadism (low sex hormones) in patients with chronic pancreatitis (as determined by sex hormone levels and clinical history). iii) Identification of hypogonadism and/or opioid use as risk factors for low bone density in patients with chronic pancreatitis (as determined by univariate and multivariate analysis of multiple risk factors). After obtaining written consent from potential subjects, a questionnaire will be performed outlining risk factors for low bone density. Dual X-ray absorptiometry (DXA scan) will be performed to evaluate for low bone density and a blood test will be performed to evaluate for low sex hormones, low levels of vitamin D, and other risk factors for low bone density.
