Pancreatic enzyme replacement therapy

BACKGROUND: Exocrine pancreatic insufficiency (EPI) can be associated with all types of diabetes. Pancreatic enzyme replacement therapy (PERT) has short and long-term benefits in subjects with EPI, but its effects on diabetes control are uncertain. We aimed to study the effects of PERT initiation on glycemic control in subjects with diabetes and EPI from any cause. METHODS: In this retrospective study, we compared subjects with EPI and diabetes who were prescribed PERT with subjects with diabetes who had a fecal elastase-1 concentration dosage, but did not receive PERT...

Lactate dehydrogenase A (LDHA) serves as a key regulator of the Warburg Effect by catalyzing the conversion of pyruvate to lactate in the final step of glycolysis. Both the expression level and enzyme activity of LDHA are upregulated in cancers, however, the underlying mechanism remains incompletely understood. Here, we show that LDHA is post-translationally palmitoylated by ZDHHC9 at cysteine 163, which promotes its enzyme activity, lactate production, and reduces reactive oxygen species (ROS) generation. Replacement of endogenous LDHA with a palmitoylation-deficient mutant leads to reduced pancreatic cancer cell proliferation, increased T-cell infiltration, and limited tumor growth; it also affects pancreatic cancer cell response to chemotherapy...

BACKGROUND: Disconnected pancreatic duct syndrome (DPDS) is a common cause of recurrent pancreatic fluid collections (PFCs), often requiring repeat drainage. Following initial drainage with lumen apposing metal stents (LAMS), replacement with transmural double pigtail stents (DPS) has been shown to be a viable drainage modality mitigating the risk of recurrence. The sparsity of literature on the consequences of this strategy requires further investigation. We analyze our outcomes of long-term transmural drainage with DPS in patients with DPDS and assess the safety and efficacy of this technique...

INTRODUCTION: Chemotherapy combined with immune checkpoint inhibitors (ChIM) is used to treat advanced pancreatic ductal adenocarcinoma (PDAC). However, the efficacy of ChIM is similar to that of chemotherapy alone. METHODS: To assess potential factors affecting the effectiveness of ChIM, we analyzed the clinical data of 359 patients with PDAC who visited the hospital during June 2017 to December 2022. RESULTS: Surgical resection, diabetes, and ChIM were risk factors for pancreatic exocrine insufficiency (PEI)...

Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical treatment option for patients with chronic pancreatitis who have not responded to other therapies. TP offers pain relief whereas IAT preserves beta cell mass to reduce endocrine insufficiency. During the surgical procedure, the entire pancreas is removed. Islet cells from the pancreas are then isolated, purified, and infused into the liver via the portal vein. Successful TPIAT relieves pain for a majority of patients but is not without obstacles, specifically gastrointestinal, exocrine, and endocrine challenges...

BACKGROUND: Pancreatic enzyme replacement therapy (PERT) is the standard treatment for exocrine pancreatic insufficiency (EPI). However, many individuals are inadequately treated, with gaps in clinical dosing, guidelines, and tools to aid individual titration. METHODS: A systematic review identified research and guidelines on PERT dosing recommendations across conditions, systematically reviewing and synthesizing total PERT intake, meal/snack guidelines, and changes over time to provide an up-to-date look at the most common doses used in studies and guidelines...

INTRODUCTION: Pancreatic exocrine insufficiency (PEI) is common after gastric resection for cancer or ulcers but is under-recognized and undertreated. Although pancreatic enzyme replacement therapy (PERT) is the mainstay of PEI management, robust evidence supporting its use after gastric surgery is limited. AREAS COVERED: In the absence of guideline recommendations specific for patients with pancreatic insufficiency after gastrectomy, a panel of experts from different geographical regions convened in a virtual meeting to discuss their approach to patient management...

OBJECTIVE: Preparation for transition from pediatric to adult cystic fibrosis (CF) care is essential for successful self-management in adulthood. The primary objective of this study was to determine if education improved performance on follow-up assessments to increase knowledge for transition into adult care. The secondary objective of this study was to identify areas of greatest educational opportunity for adolescent CF patients. METHODS: A knowledge assessment containing 13 multiple-choice questions was given to patients between 14 and 19 years of age...

For children with diminished quality of life and chronic pain caused by acute recurrent or chronic pancreatitis who are undergoing total pancreatectomy with islet autotransplantation, postoperative nutrition support has several unique characteristics. Surgical complications may lead to delays in nutrition support initiation or require modifications to the regimen. Early postoperative dysmotility requires the use of temporary enteral nutrition until this improves. The resultant complete exocrine pancreatic insufficiency necessitates lifelong pancreatic enzyme replacement therapy and fat-soluble vitamin supplementation...

BACKGROUND: Untreated pancreatic exocrine insufficiency (PEI) results in substantial patient harm. Upper gastrointestinal surgery (bariatric metabolic surgery and oesophagogastric resection) affects the delicate physiology of pancreatic exocrine function and may result in PEI. The aim of this study was to assimilate the literature on incidence, diagnosis, and management of PEI after bariatric metabolic surgery and oesophagogastric resection. METHODS: A systematic review of PubMed, MEDLINE, and Embase databases identified studies investigating PEI after non-pancreatic upper gastrointestinal surgery...

Being an underdiagnosed and under or insufficiently treated condition, surgical pancreatic exocrine insufficiency (PSP) is the condition in which pancreatic enzymes are insufficient for digestion because of gastrointestinal (GI) surgery involving the upper GI tract, biliary ducts, or the pancreas, and and leading to potential malnutrition and deterioration in quality of life. Age, obesity, history of tobacco use, family history of diabetes, surgery due to a malignant tumor, presence of steatorrhea, jaundice, weight loss, and intraoperative findings of hard pancreatic texture have been associated with a higher risk of PSP...

OBJECTIVES: This study aimed to provide patients insights on the management of exocrine pancreatic insufficiency (EPI) with pancreatic enzyme replacement therapy (PERT). MATERIALS AND METHODS: A survey of 75 members of Inspire's Pancreatitis or Pancreatic Cancer Support communities was conducted. Eligibility included having EPI secondary to chronic pancreatitis, pancreatic cancer, pancreatic surgery, or acute pancreatitis, and current/past PERT experience. RESULTS: Patients were 73% female, 57% aged 50 to 69 years, and 85% White, with PERT prescribed by a gastroenterologist/pancreatologist for 64%...

BACKGROUND: Pancreatic cancer is relatively rare and aggressive, with digestion and malabsorption issues often leading to significant weight loss. Recruitment of people with this malignancy into studies can be challenging, and innovative methods need to be explored to improve recruitment rates. AIM: To describe a mixed media methodology and the outcomes used to recruit patients to participate in a binational survey. METHODS: The details of the mixed media method used to identify and recruit people with pancreatic cancer are described...

Pancreatic exocrine insufficiency (PEI) is common amongst pancreatic cancer patients and is associated with poorer treatment outcomes. Pancreatic enzyme replacement therapy (PERT) is known to improve outcomes in pancreatic cancer, but the mechanisms are not fully understood. The aim of this narrative literature review is to summarise the current evidence linking PEI with microbiome dysbiosis, assess how microbiome composition may be impacted by PERT treatment, and look towards possible future diagnostic and therapeutic targets in this area...

Exocrine pancreatic insufficiency (EPI) is a malabsorptive syndrome caused by insufficient secretion of digestive enzymes from pancreatic acini. The most common causes of EPI in dogs and cats are pancreatic acinar atrophy and chronic pancreatitis. EPI is diagnosed by measurement of species-specific immunoassays for serum trypsin-like immunoreactivity, the concentration of which directly reflects the mass of functioning pancreatic acinar tissue. EPI is treated by pancreatic enzyme replacement therapy, nutritional management (low-residue diets with moderate fat content), and supplementation of cobalamin...

AIM: To analyze the effect of etiological factors such as tobacco and alcohol and pancreatic enzyme replacement therapy (PERT) in the progression of CP. MATERIAL AND METHODS: Patients with a diagnosis of CP were recruited and grouped according to variables such as tobacco, alcohol and PERT. They were followed for 18 months. Subsequently, different variables and analytical parameters involved in the progression of the disease were analyzed...

BACKGROUND: The finding of pancreatic cystic lesions (PCL) on incidental imaging is becoming increasingly common. International studies report a prevalence of 2.2-44.7% depending on the population, imaging modality and indication for imaging, and the prevalence increases with age. Patients with PCL are at risk of developing pancreatic cancer, a disease with a poor prognosis. This publication summarizes recommendations for the diagnosis and management of PCL and post-operative pancreatic exocrine insufficiency (PEI) from a group of local specialists...

BACKGROUND: High daily doses of pancreatic enzyme replacement therapy (PERT) were historically associated with risk of fibrosing colonopathy (FC) in people with cystic fibrosis (pwCF), leading to development of PERT dosing guidelines and reformulated products. This study quantified incidence of FC in pwCF treated with PERT following those measures. METHODS: This large prospective cohort study included eligible pwCF enrolled in the Cystic Fibrosis Foundation Patient Registry with ≥1 clinic visit in 2012-2014 and follow-up through 2020...
