Pancreatic exocrine insufficiency (PEI) is defined as a reduction in pancreatic exocrine secretion below the level that allows the normal digestion of nutrients. Pancreatic disease and surgery are the main causes of PEI. However, other conditions and upper gastrointestinal surgery can also affect the digestive function of the pancreas. PEI can cause symptoms of nutritional malabsorption and deficiencies, which affect the quality of life and increase morbidity and mortality. These guidelines were developed following the United European Gastroenterology framework for the development of high-quality clinical guidelines. After a systematic literature review, the evidence was evaluated according to the Oxford Center for Evidence-Based Medicine and the Grading of Recommendations Assessment, Development, and Evaluation methodology, as appropriate. Statements and comments were developed by the working groups and voted on using the Delphi method. The diagnosis of PEI should be based on a global assessment of symptoms, nutritional status, and a pancreatic secretion test. Pancreatic enzyme replacement therapy (PERT), together with dietary advice and support, are the cornerstones of PEI therapy. PERT is indicated in patients with PEI that is secondary to pancreatic disease, pancreatic surgery, or other metabolic or gastroenterological conditions. Specific recommendations concerning the management of PEI under various clinical conditions are provided based on evidence and expert opinions. This evidence-based guideline summarizes the prevalence, clinical impact, and general diagnostic and therapeutic approaches for PEI, as well as the specifics of PEI in different clinical conditions. Finally, the unmet needs for future research are discussed.

This study aimed to investigate the prevalence and types of errors associated with oral medication administration via feeding tubes (FTs) in a tertiary hospital in Beijing.

A retrospective observational study was conducted at Beijing Hospital between January 2018 and December 2022. All inpatients aged of 18 and above who received at least one oral medication via FTs were included. Medical records were meticulously collected and analyzed.

A total of 7,243 patients were identified as part of the tube feeding group, representing a prevalence rate of 6.26% among hospitalized patients receiving oral medication. Compared to the general hospitalized population, patients in the tube feeding group exhibited a higher proportion of male patients (59.74% vs 48.91%), older age [(68.00±14.99) vs (59.75±16.38)], lower weight [(65.75±13.32) vs (67.82±12.72)], increased rates of being bedridden (18.06% vs 5.38%), longer hospital stay [(21.56±28.12) vs (8.88±10.38)], and a greater number of prescribed medication types [(51.21±19.37) vs (23.35±15.04)]. On average, patients in the tube feeding group were administered 8.92±6.78 types of oral medications. A significant percentage of patients in the tube feeding group experienced inappropriate medication administration, reaching 65.43%. Among these cases, the rate of inappropriate medication administration for patients receiving nasogastric tube and nasojejunal tube were 64.06% (4186/6535) and 78.11% (553/708), respectively. In total, there were 10,164 instances of inappropriate medication administration, averaging 1.40 times per patient in the tube feeding group. Inappropriate medications included enteric-coated drugs, modified-released, soft capsules, and other non-crushable drugs.

Our results Our findings highlight a significant issue of inappropriate medication administration via FTs. Ensuring the accurate administration of orally prescribed medications to patients with FTs is a complex task that requires immediate attention.

Exocrine pancreatic insufficiency (EPI) is a complex condition that disrupts normal digestion and absorption. Patients with EPI may suffer from mild to debilitating malabsorption with a constellation of symptoms that can have a significant effect on quality of life and nutrition status. Pancreatic enzyme replacement therapy (PERT) is effective and safe to treat EPI and is the standard of care for this condition. A wide variety and various forms of these products exist, as well as numerous guidelines and recommendations. Obtaining PERT for patients can oftentimes be cost prohibitive. Determining the presence and extent of EPI can be challenging and patient specific, making it difficult for practitioners. This narrative review will explore these issues, as well as several disease states potentially affected by EPI, and review current management strategies.

Most patients with pancreatic cancer at some point present with symptoms related to exocrine pancreatic insufficiency (EPI). These include diarrhea, abdominal bloating, indigestion, steatorrhea, weight loss, and anorexia. Even though up to 80% of pancreatic cancer patients eventually present with symptoms related to exocrine pancreatic insufficiency, only 21% are prescribed pancreatic enzyme replacement therapy (PERT). Its effectiveness is also highly dependent on its proper timing of administration, and patients must be thoroughly educated about this. The impact of symptoms of EPI can lead to poorer overall well-being. Pharmacists play a crucial role in properly educating patients on the correct use of pancreatic enzyme replacement therapy. PERT is a key strategy in managing the symptoms of EPI and can improve quality of life, which is a central focus in palliative care. This treatment is profoundly underutilized in the palliative care of these patients. The objective of this review is to discuss the pharmacology, pharmacokinetics, side effects, available evidence of the effectiveness of pancreatic enzyme use for patients with pancreatic cancer, and challenges, along with proposed solutions regarding its use.

Both acute and chronic pancreatitis are frequent diseases of the pancreas, which, despite being of benign nature, are related to a significant risk of malnutrition and may require nutritional support. Acute necrotizing pancreatitis is encountered in 20 % of patients with acute pancreatitis, is associated with increased morbidity and mortality, and may require artificial nutrition by enteral or parenteral route, as well as additional endoscopic, radiological or surgical interventions. Chronic pancreatitis represents a chronic inflammation of the pancreatic gland with development of fibrosis. Abdominal pain leading to decreased oral intake, as well as exocrine and endocrine failure are frequent complications of the disease. All of the above represent risk factors related to malnutrition. Therefore, patients with chronic pancreatitis should be considered at risk, screened and supplemented accordingly. Moreover, osteoporosis and increased facture risk should be acknowledged in patients with chronic pancreatitis, and preventive measures should be considered.

As operative techniques and mortality rates of pancreatectomy have improved, there has been a shift in focus to maintaining and improving the nutritional status of these patients as we continue to learn more about post-operative complications. Although pancreatic endocrine and exocrine insufficiencies are known complications of pancreatectomy, increased longevity of these patients has also led to a higher incidence of de novo fatty liver disease which differs from traditional fatty liver disease given the lack of metabolic syndrome.

To identify and summarize patterns and risk factors of post-pancreatectomy de novo fatty liver disease to guide future management.

We performed a database search on PubMed selecting papers published between 2001 and 2022 in the English language. PubMed was last accessed 1 June 2022.

Various factors influence the development of de novo fatty liver including indication for surgery (benign vs malignant), type of pancreatectomy, amount of pancreas remnant, and peri-operative nutritional status. With an incidence rate up to 75%, de novo non-alcoholic fatty liver disease (NAFLD) can develop within 12 mo after pancreatectomy and various risk factors have been established including pancreatic resection line and remnant pancreas volume, peri-operative malnutrition and weight loss, pancreatic exocrine insufficiency (EPI), malignancy as the indication for surgery, and postmenopausal status.

Since majority of risk factors leads to EPI and malnutrition, peri-operative focus on nutrition and enzymes replacement is key in preventing and treating de novo NAFLD after pancreatectomy.

Gastrointestinal (GI) symptoms are often reported by CF patients. Despite a proven relation to exocrine pancreatic insufficiency (PI), it remains unclear whether GI symptoms are related to the timing of pancreatic enzyme replacement therapy (PERT). Whereas most international recommendations suggest administration of PERT at the beginning of meals, it has not been studied whether such a proceeding is associated with lower burden of symptoms.

Thirty CF patients aged 0-17 years of age with PI were randomised to four weeks of PERT prior to meals followed by four weeks of PERT after meals or vice versa. Using the CF-specific validated CFAbd-Score, abdominal pain, dysfunctional bowel habits and Quality of Life (QoL) related to GI symptoms were assessed in relation to the timing of PERT. Data were analysed using a linear mixed model.

There was no significant difference regarding abdominal pain, bowel habits or QoL related to GI symptoms when timing of PERT was changed from prior to after meals.

No significant difference was found when administration mode of PERT changed from prior to after meals or vice versa. However, after an individual assessment, some patients may profit from changing administration mode of PERT from prior to after meals.

Pancreatic exocrine insufficiency is a finding in many conditions, predominantly affecting those with chronic pancreatitis, pancreatic cancer and acute necrotising pancreatitis. Patients with pancreatic exocrine insufficiency can experience gastrointestinal symptoms, maldigestion, malnutrition and adverse effects on quality of life and even survival.There is a need for readily accessible, pragmatic advice for healthcare professionals on the management of pancreatic exocrine insufficiency.

A review of the literature was conducted by a multidisciplinary panel of experts in pancreatology, and recommendations for clinical practice were produced and the strength of the evidence graded. Consensus voting by 48 pancreatic specialists from across the UK took place at the 2019 Annual Meeting of the Pancreatic Society of Great Britain and Ireland annual scientific meeting.

Recommendations for clinical practice in the diagnosis, initial management, patient education and long term follow up were developed. All recommendations achieved over 85% consensus and are included within these comprehensive guidelines.

Nutritional management is an integral part of multidisciplinary care for persons with cystic fibrosis. This review will look at how nutrition care has evolved over time. In addition, we will look at how some newer therapies impact nutrition care.

This clinical observation describes the enteral nutrition (EN) management of 2 toddlers at high nutrition risk due to cystic fibrosis (CF), exocrine pancreatic insufficiency, and comorbid medical conditions. The first case report describes a boy with severe malabsorption after intestinal resection. The second case report reviews a boy with CF and neuroblastoma. When pancreatic enzyme replacement therapy with EN was not effective or appropriate, use of an in-line digestive cartridge was initiated. While using the digestive cartridge, both children showed improvements in their anthropometric measures. This observation reviews the nutrition management throughout their clinical course and describes the use of a digestive cartridge with EN.

Pancreatic cancer is often diagnosed at late stages, where disease is either locally advanced unresectable or metastatic. Despite advances, long-term survival is relatively non-existent.

This review article discusses clinical factors commonly encountered in practice that should be incorporated into the decision-making process to optimize patient outcomes, including performance status, nutrition and cachexia, pain, psychological distress, medical comorbidities, advanced age, and treatment selection.

Identification and optimization of these clinical factors could make a meaningful impact on the patient's quality of life.

Malnutrition is a frequent complication in patients with chronic pancreatitis. Maldigestion as a consequence of pancreatic exocrine insufficiency is the major cause of malnutrition in these patients. Together with that, toxic habits and alterations of the gastroduodenal transit may play a relevant role. Malnutrition in chronic pancreatitis is associated with osteoporosis, sarcopenia, poor quality of life, and increased mortality. An adequate nutritional evaluation including anthropometric, biochemical, and morphologic parameters is recommended in these patients. Nutritional advice and support together with an adequate pancreatic enzyme replacement therapy are indicated.

Nutrition is integral to the care of individuals with cystic fibrosis (CF). Better nutritional status is associated with improved pulmonary function. In some individuals with CF, enteral tube feeding can be useful in achieving optimal nutritional status. Current nutrition guidelines do not include detailed recommendations for enteral tube feeding. The Cystic Fibrosis Foundation convened an expert panel to develop enteral tube feeding recommendations based on a systematic review of the evidence and expert opinion. These guidelines address when to consider enteral tube feeding, assessment of confounding causes of poor nutrition in CF, preparation of the patient for placement of the enteral feeding tube, management of the tube after placement and education about enteral feeding. These recommendations are intended to guide the CF care team, individuals with CF, and their families through the enteral tube feeding process.

To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature.

Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important.

A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included. The top-ranked articles from the primary literature were reviewed.

It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these articles.

Close attention to nutrition and growth is essential in caring for children with cystic fibrosis (CF). Growth and nutritional status should be monitored as part of routine CF care. Children with CF should achieve growth and nutritional status comparable with that of well-nourished children without CF. Children with CF are at risk for nutritional deficiencies. Optimal nutritional and growth status may be difficult to attain in this population given risk of insufficient caloric intake and likelihood of increased caloric expenditure. Various methods to attain optimal nutritional status may be used, including oral supplementation, behavioral treatment, pharmacotherapy, and enteral nutrition.

This study evaluated nutrition status to determine the impact of a novel approach using elemental nutrition compared to pancrelipase administration in patients with pancreatitis.

This retrospective study included adult patients with pancreatitis who were nil per os (NPO) and received elemental nutrition from August 2008 to 2010 (n = 24) or pancrelipase enzyme supplementation (PES) plus nonelemental enteral nutrition from August 2011 to 2013 (n = 41) at a large academic medical center. The primary outcome is the percentage of diarrhea-free days. Secondary outcomes include time-to-goal enteral nutrition from the enteral nutrition initiation and pre-albumin and albumin changes pre- and postenteral nutrition.

There were no statistically significant differences between the 2 groups in percentage of diarrhea-free days (46.80% ± 29.03% vs 53.45% ± 36.76%, p = 0.45). Additionally, there were no differences in secondary outcomes of time-to-goal enteral nutrition and pre-albumin and albumin changes pre- and postenteral nutrition.

Utilizing elemental nutrition compared to PES plus nonelemental enteral nutrition in patients with pancreatitis was not associated with a significant reduction in percentage of diarrhea-free days, time-to-goal enteral nutrition, and nutrition status. A multicenter, prospective, randomized, controlled trial is warranted to further evaluate the efficacy of elemental nutrition in patients with pancreatitis.

Despite significant advancements made in life expectancy over the past century, cystic fibrosis remains a life-threatening genetic disease that affects the gastrointestinal tract, and it has significant impact on the nutrition status of those with the disease. Nutrition management includes a high-calorie/high-fat diet, pancreatic enzyme replacement therapy, vitamin and mineral replacement, and enteral support as needed. As patients are living longer, clinicians may encounter patients with cystic fibrosis in obstetrician offices, endocrine clinics, or hospital settings, owing to lung transplantation or for treatment for distal intestinal obstruction syndrome.

Untreated pancreatic exocrine dysfunction is associated with poor quality of life and reduced survival, but is difficult to diagnose following pancreatic resection. Many factors including the extent of the surgery, the health of the residual pancreas and the type of reconstruction must be considered. Patients remain undertreated, and consequently there is much debate to whether or not pancreatic enzyme replacement therapy should be routinely prescribed following pancreatic resection.

A review of the literature was undertaken to establish the incidence of PEI and factors identifying treatment.

Forty two to forty five percent of patients undergoing pancreatico-duodenectomy (PD) experience pancreatic exocrine insufficiency pre-operatively, whilst the post-operative incidence is 56-98% in PD, and 12-80% following distal and central pancreatectomy.

Routine use of pancreatic enzyme replacement should be considered at a starting dose of 50 to 75,000 units lipase with meals and 25,000 to 50,000 units with snacks in this patient group. Patients who have had a central or distal pancreatectomy should be individually assessed for pancreatic exocrine insufficiency in the post operative period, with those undergoing extensive resection most likely to experience insufficiency. Patients who fail to respond to pancreatic enzyme replacement therapy should be referred to a specialist dietitian, be advised on dose adjustment, and undergo investigation to exclude other gastro-intestinal pathology, including small bowel bacterial overgrowth and bile acid malabsorption.

Cystic fibrosis can affect food digestion and nutrient absorption. The underlying mutation of the cystic fibrosis trans-membrane regulator gene depletes functional cystic fibrosis trans-membrane regulator on the surface of epithelial cells lining the digestive tract and associated organs, where Cl(-) secretion and subsequently secretion of water and other ions are impaired. This alters pH and dehydrates secretions that precipitate and obstruct the lumen, causing inflammation and the eventual degradation of the pancreas, liver, gallbladder and intestine. Associated conditions include exocrine pancreatic insufficiency, impaired bicarbonate and bile acid secretion and aberrant mucus formation, commonly leading to maldigestion and malabsorption, particularly of fat and fat-soluble vitamins. Pancreatic enzyme replacement therapy is used to address this insufficiency. The susceptibility of pancreatic lipase to acidic and enzymatic inactivation and decreased bile availability often impedes its efficacy. Brush border digestive enzyme activity and intestinal uptake of certain disaccharides and amino acids await clarification. Other complications that may contribute to maldigestion/malabsorption include small intestine bacterial overgrowth, enteric circular muscle dysfunction, abnormal intestinal mucus, and intestinal inflammation. However, there is some evidence that gastric digestive enzymes, colonic microflora, correction of fatty acid abnormalities using dietary n-3 polyunsaturated fatty acid supplementation and emerging intestinal biomarkers can complement nutrition management in cystic fibrosis.

Administration of pancreatic enzymes (pancrelipase) to adult patients with cystic fibrosis when receiving enteral nutrition through a feeding tube is challenging. A number of techniques for preparing and administering the drug may result in complications that include feeding tube occlusion and inadequate enzyme delivery to the patient. A series of inpatient encounters is described.

The aim of the present study was to better understand the exocrine pancreatic function of extremely preterm infants.

Pancreatic-specific elastase 1 (PSE1) activity was determined in spot stool samples of 69 preterm infants of gestational age <32 weeks and birth weight <1250 g. Assays were conducted on samples collected at 2 (N = 56), 4 (N = 46), and 6 weeks of age (N = 23).

PSE1 activity increased from week 2 (median [interquartile range] 84 [48-187] μg/g) to week 4 (164 [87-251 μg/g; P < 0.001) but not thereafter (169 [82-298] μg/g at week 6). The maturational increase in PSE1 activity was observed only in infants of gestational age <28 weeks (P < 0.001). At 2 weeks after birth, PSE1 levels were lower in infants of gestational age <28 weeks than in infants of gestational age ≥ 28 weeks (77 [43-110] vs 165 [56-300] μg/g; P = 0.019), but this difference was less pronounced at 4 weeks (153 [77-226] vs 230 [108-503] μg/g; P = 0.070) and had disappeared by 6 weeks (163 [76-258] vs 175 [85-418] μg/g; P = 0.576). In infants on full enteral feeding regimens 4 weeks after birth, PSE1 levels were associated with weight gain per unit of energy intake (Rs = 0.431; P = 0.005). This measure of weight gain was lower (P = 0.040) in infants with PSE1 levels <200 μg/g (0.110 [0.081-0.139] g/kcal, N = 25) than in those with PSE1 levels ≥ 200 μg/g (0.139 [0.117-0.157] g/kcal, N = 15). Administration of pancreatic enzymes to infants showing PSE1 excretion levels <200 μg/g did not enhance weight gain.

: Extremely preterm infants have limited exocrine pancreatic function during the first weeks of life, which may contribute to growth failure.

Pancreatic surgery is a complicated procedure leaving postoperative patients with an altered gastrointestinal (GI) anatomy and a potential for further surgical complications such as leaks and fistulas. Beyond surgical complications, these patients are prone to delayed gastric emptying, fat malabsorption, and hyperglycemia, with early satiety and poor appetite further compromising nutrition status. Many of these patients are malnourished prior to this major surgical procedure, and significant weight loss is common postoperatively. Does this affect their outcome? There seems to be a lack of consensus in this patient population regarding how to optimize nutrition and limit potential deleterious effects of this surgery. It is important to first understand the underlying disease condition and the effects to the gland, different forms of surgery with subsequent GI alterations, and common surgical and digestive complications. Once this is reviewed, existing nutrition support literature will be explored in attempts to determine the best nutrition management in this patient population.

Pancreatic exocrine insufficiency (PEI) is often observed in patients with pancreatic diseases, including chronic pancreatitis, cystic fibrosis, and tumors, or after surgical resection. PEI often results in malnutrition, weight loss and steatorrhea, which together increase the risk of morbidity and mortality. Therefore, nutritional interventions, such as low-fat diets and pancreatic enzyme replacement therapy (PERT), are needed to improve the clinical symptoms, and to address the pathophysiology of pancreatic exocrine insufficiency. PERT with delayed-release pancrelipase is now becoming a standard therapy for pancreatic exocrine insufficiency because it significantly improves the coefficients of fat and nitrogen absorption as well as clinical symptoms, without serious treatment-emergent adverse events. The major adverse events were tolerable gastrointestinal tract symptoms, such as stomach pain, nausea, and bloating. Fibrosing colonopathy, a serious complication, is associated with high doses of enzymes. Several pancrelipase products have been approved by the US Food and Drug Administration in recent years. Although many double-blind, placebo-controlled trials of pancrelipase products have been conducted in recent years, these studies have enrolled relatively few patients and have often been less than a few weeks in duration. Moreover, few studies have addressed the issue of pancreatic diabetes, a type of diabetes that is characterized by frequent hypoglycemia, which is difficult to manage. In addition, it is unclear whether PERT improves morbidity and mortality in such settings. Therefore, large, long-term prospective studies are needed to identify the optimal treatment for pancreatic exocrine insufficiency. The studies should also examine the extent to which PERT using pancrelipase improves mortality and morbidity. The etiology and severity of pancreatic exocrine insufficiency often differ among patients with gastrointestinal diseases or diabetes (type 1 and type 2), and among elderly subjects. Finally, although there is currently limited clinical evidence, numerous extrapancreatic diseases and conditions that are highly prevalent in the general population may also be considered potential targets for PERT and related treatments.

In clinical practice, the need sometimes arises to administer pancreatic enzyme replacement therapy via gastrostomy tube (G-tube) by mixing the pellets contained in the capsules with soft food. The objective of this study was to identify G-tubes that allow administration of pancrelipase gastro-resistant pellets without clogging, sticking, pellet damage or loss of enteric coating integrity.

In this in vitro study, CREON® (pancrelipase) Delayed-Release Capsules were opened and the pellets sprinkled onto a small amount of baby food of pH <4.5 (applesauce and bananas manufactured by both Gerber and Beech-Nut). The mixture was stirred gently and after 15 minutes poured into a 35 mL syringe and pushed slowly (~15 mL in 10-15 seconds) through a G-tube. Pellets were collected and the tube flushed with water. G-tubes were inspected visually for clogging/sticking and damage to pellets was assessed. If there was none with all four foods, pellet integrity (gastric resistance and lipase activity) was assessed by an in vitro dissolution method with a 2-hour gastric simulation step. The activity required to confirm integrity was ≥80% of actual US Pharmacopeia lipase activity per capsule. G-tubes initially tested were Kimberly-Clark MIC Bolus® size 14 French (Fr) and upwards and Kimberly-Clark MIC-KEY® 14 Fr and upwards. Following successful testing, assessment of Bard® Tri-Funnel 18 Fr and Bard® Button 18 Fr G-tubes was carried out.

Based on the absence of clogging, sticking and visible damage to pellets, and the maintenance of pellet integrity, administration of CREON® pancrelipase pellets was feasible through the following G-tubes: Kimberly-Clark MIC Bolus® size 18 Fr, Kimberly-Clark MIC-KEY® 16 Fr, Bard® Tri-Funnel 18 Fr and Bard® Button 18 Fr. Lipase activity met the predetermined specification and was ≥90% for all four tubes and all four foods, with no differences versus untreated pellets (i.e. pellets not mixed with baby food or pushed through a G-tube). These data apply to all CREON® pancrelipase capsule formulations, regardless of their strength in lipase units, as pellet composition, size and quality are identical.

CREON® pancrelipase pellets can be mixed with baby food of pH <4.5 and administered via the following G-tubes without clogging, sticking or visible pellet damage, and with no loss of gastric resistance or lipase activity: Kimberly-Clark MIC Bolus® size 18 Fr and larger, Kimberly-Clark MIC-KEY® 16 Fr and larger, Bard® Tri-Funnel 18 Fr and larger and Bard® Button 18 Fr and larger.
