Abstract
While common pancreatic diseases, such as acute pancreatitis (AP), chronic pancreatitis (CP), and pancreatic cancer (PC), may greatly impact the normal pancreatic physiology and contribute to malnutrition, the adequate nutritional approach when those conditions are present significantly influences patients' prognosis. In patients with AP, the goals of nutritional care are to prevent malnutrition, correct a negative nitrogen balance, reduce inflammation, and improve outcomes such as local and systemic complications and mortality. Malnutrition in patients with CP is common but often a late manifestation of the disease, leading to decreased functional capacity and quality of life and increased risk of developing significant osteopathy, postoperative complications, hospitalization, and mortality. Cancer-related malnutrition is common in patients with PC, and it is now well recognized that early nutritional support can favorably impact survival, not only by increasing tolerance and response to disease treatments but also by improving quality of life and decreasing postoperative complications. The aim of this review was to emphasize the role of nutrition and to propose a systematic nutritional approach in patients with AP, CP, and PC.

Abstract
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.

Abstract
PURPOSE OF REVIEW This review aims to discuss recent developments in the nutritional management in chronic pancreatitis. RECENT FINDINGS Nutritional assessment should be comprehensive and include dietary history, anthropometry, and biochemical nutritional parameters. Micronutrients should be evaluated at least yearly and dual-energy X-ray absorptiometry (DEXA) at every 2-yearly intervals. Studies on pancreatic enzyme replacement therapy (PERT) have primarily evaluated coefficient of fat excretion (CFA), coefficient of nitrogen excretion (CNA), and stool weight. Two RCTs, in which patients were treated with PERT for 7 days in a blinded manner and subsequently extended for 6-12 months in an open-label manner, showed improvement in nutritional parameters. However, two subsequent RCTs failed to show any benefit, and the most recent observational study demonstrated persistence of malnutrition even after PERT. The reason for the latter findings were nonadherence to PERT and poor oral intake of calories. Therefore, it is essential to educate the patients on adherence, counsel on taking high-protein, high-calorie diet, and supplement nutrients in those with inadequate oral intake. Other associated manifestations, such as diabetes and related complications, and anxiety/depression could also contribute to malnutrition directly or indirectly, and should, therefore, be adequately managed. SUMMARY Nutritional assessment should be performed meticulously. Nutritional therapy should not be restricted to only PERT and nutritional supplementation, but should also include dietary counselling and disease related education.

Nutritional management of chronic pancreatitis: A systematic review and meta-analysis of randomized controlled trials. J Gastroenterol Hepatol 2021; 36:588-600.

Abstract
BACKGROUND AND AIM Malnutrition is a frequent complication of chronic pancreatitis. Adequate nutritional support is imperative, but there is still uncertainty about the optimal nutritional treatment. This work systematically compiles evidence from randomized controlled trials investigating dietary interventions in chronic pancreatitis and, in a further step, contrasts those findings with existing dietary recommendations. METHODS The literature search (PubMed and Cochrane Central Register of Controlled Trials) included English and German full-text articles, which had been published in peer-reviewed journals. Two independent reviewers identified and selected studies. For meta-analysis, forest plots with 95% confidence intervals were generated using a random-effects model. RESULTS Eleven randomized controlled trials fulfilled all selection criteria. In these trials, the following dietary interventions were tested: antioxidant treatment (n = 6), vitamin D supplementation (n = 3), supplementation with oral nutritional supplements (n = 1), and symbiotics supplementation (n = 1). Studies were of good methodological quality (mean Jadad score of 3.6) but heterogeneous in terms of interventions and study populations. Only for vitamin D, there was convincing evidence for efficacy of supplementation. We found no effect for antioxidant treatment on pain relief (standardized mean difference = -0.12; 95% confidence interval -0.73 to 0.48) and limited generalizability for interventions with oral nutritional supplements and symbiotics. CONCLUSIONS Nutritional management in chronic pancreatitis remains challenging. As well-designed randomized controlled trials are scarce, in large part, recommendations can only be based on low-level evidence studies or expert opinion. For now, consumption of a balanced diet remains the cornerstone recommendation for prevention, whereas more goal-directed interventions are indicated for specific nutrient deficiencies.

Abstract
Pancreaticoduodenectomy (PD) is the commonest procedure performed for pancreatic cancer. Pancreatic exocrine insufficiency (PEI) may be caused or exacerbated by surgery and remains underdiagnosed and undertreated. The aim of this review was to ascertain the incidence of PEI, its consequences and management in the setting of PD for indications other than chronic pancreatitis. A literature search of databases (MEDLINE, EMBASE, Cochrane and Scopus) was carried out with the MeSH terms “pancreatic exocrine insufficiency” and “Pancreaticoduodenectomy”. Studies that analysed PEI and its complications in the setting of PD for malignant and benign disease were included. Studies reporting PEI in the setting of PD for chronic pancreatitis, conference abstracts and reviews were excluded. The incidence of PEI approached 100% following PD in some series. The pre-operative incidence varied depending on the characteristics of the patient cohort and it was higher (46%-93%) in series where pancreatic cancer was the predominant indication for surgery. Variability was also recorded with regards to the method used for the diagnosis and evaluation of pancreatic function and malabsorption. Pancreatic enzyme replacement therapy is the mainstay of the management. PEI is common and remains undertreated after PD. Future studies are required for the identification of a well-tolerated, reliable and reproducible diagnostic test in this setting.

Abstract
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.

Abstract
Pancreatic exocrine insufficiency (PEI) frequently occurs secondary to exocrine pancreatic disease (e.g. chronic pancreatitis, cystic fibrosis, cancer) or pancreatic/gastrointestinal surgery, resulting in the maldigestion of nutrients and consequently malnutrition. Pancreatic enzyme replacement therapy (PERT) is the cornerstone of PEI management. Despite its clinical relevance, the diagnosis of PEI in clinical practice is challenging, as the current gold standard test is cumbersome, and alternatives have limited availability or accuracy. There is a need for accurate and easily applicable diagnostic modalities. We review the prevalence of clinical symptoms and changes in anthropometric measurements and laboratory nutritional markers indicative of malnutrition in patients with PEI, and the relevance of these findings in diagnosing PEI and monitoring PERT efficacy. Based on limited available evidence, assessment of clinical symptoms, body weight, body mass index and other anthropometric parameters are not sensitive methods for PEI diagnosis, owing to high variability and multiple confounding factors, but appear useful in monitoring PERT efficacy. Limited evidence precludes strong recommendations but suggests that serum levels of vitamin E, magnesium, and plasma proteins, notably retinol binding protein, albumin, and prealbumin, may have diagnostic utility in PEI. Studies show that assessment of changes in these and other nutritional parameters is helpful in monitoring PERT efficacy. Further research is needed to confirm the diagnostic accuracy of these parameters for PEI. Until such data are available, a nutritional evaluation including circulating vitamin E, magnesium, retinol binding protein, albumin, and prealbumin may be used to evaluate the probability of PEI in clinical practice when reliable pancreatic function tests are not available.

Abstract
BACKGROUND/OBJECTIVES 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. METHODS A review of the literature was undertaken to establish the incidence of PEI and factors identifying treatment. RESULTS 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. CONCLUSIONS 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.

Abstract
Nutritional support is important because malnutrition is a major contributor to increased morbidity and mortality, decreased quality of life, increased length of hospital stay, and higher healthcare costs. Patients with gastrointestinal disease are at an increased risk of nutritional deterioration due to therapeutic dietary restriction, fasting for the diagnostic tests, loss of appetite due to anorexia or altered nutritional requirement caused by the disease itself. Therefore, it is important that gastroenterologists are aware of the nutritional status of patients and plan a treatment strategy considering patient's nutritional status. Enteral nutrition is preferred to parenteral nutrition as it is more physiologic, has fewer complications, help to prevent mucosal atrophy and maintain gut barrier function, which decrease intestinal bacterial translocation. Hence, enteral nutrition has been considered to be the most effective route for nutritional support. In this article, we will review enteral nutrition (oral nutritional supplements, enteral tube feeding) as a treatment for the patients with gastrointestinal, liver and pancreatic disease at risk of malnutrition.

Abstract
This is a medical position statement developed by the Exocrine Pancreatic Insufficiency collaborative group which is a part of the Italian Association for the Study of the Pancreas (AISP). We covered the main diseases associated with exocrine pancreatic insufficiency (EPI) which are of common interest to internists/gastroenterologists, oncologists and surgeons, fully aware that EPI may also occur together with many other diseases, but less frequently. A preliminary manuscript based on an extended literature search (Medline/PubMed, Cochrane Library and Google Scholar) of published reports was prepared, and key recommendations were proposed. The evidence was discussed at a dedicated meeting in Bologna during the National Meeting of the Association in October 2012. Each of the proposed recommendations and algorithms was discussed and an initial consensus was reached. The final draft of the manuscript was then sent to the AISP Council for approval and/or modification. All concerned parties approved the final version of the manuscript in June 2013.

Abstract
Pancreatic exocrine insufficiency (PEI) occurs when the amounts of enzymes secreted into the duodenum in response to a meal are insufficient to maintain normal digestive processes. The main clinical consequence of PEI is fat maldigestion and malabsorption, resulting in steatorrhoea. Pancreatic exocrine function is commonly assessed by conducting a 3-day faecal fat test and by measuring levels of faecal elastase-1 and serum trypsinogen. Pancreatic enzyme replacement therapy is the mainstay of treatment for PEI. In adults, the initial recommended dose of pancreatic enzymes is 25,000 units of lipase per meal, titrating up to a maximum of 80,000 units of lipase per meal. In infants and children, the initial recommended dose of pancreatic enzymes is 500 units of lipase per gram of dietary fat; the maximum daily dose should not exceed 10,000 units of lipase per kilogram of bodyweight. Oral pancreatic enzymes should be taken with meals to ensure adequate mixing with the chyme. Adjunct therapy with acid-suppressing agents may be useful in patients who continue to experience symptoms of PEI despite high-dose enzyme therapy. A dietitian experienced in treating PEI should be involved in patient management. Dietary fat restriction is not recommended for patients with PEI. Patients with PEI should be encouraged to consume small, frequent meals and to abstain from alcohol. Medium-chain triglycerides do not provide any clear nutritional advantage over long-chain triglycerides, but can be trialled in patients who fail to gain or to maintain adequate bodyweight in order to increase energy intake.

Abstract
This paper gives practical guidelines for diagnosis and treatment of chronic pancreatitis. Statements have been elaborated by working teams of experts, by searching for and analysing the literature, and submitted to a consensus process by using a Delphi modified procedure. The statements report recommendations on clinical and nutritional approach, assessment of pancreatic function, treatment of exocrine pancreatic failure and of secondary diabetes, treatment of pain and prevention of painful relapses. Moreover, the role of endoscopy in approaching pancreatic pain, pancreatic stones, duct narrowing and dilation, and complications was considered. Recommendations for most appropriate use of various imaging techniques and of ultrasound endoscopy are reported. Finally, a group of recommendations are addressed to the surgical treatment, with definition of right indications, timing, most appropriate procedures and techniques in different clinical conditions and targets, and clinical and functional outcomes following surgery.

Abstract
Newborn screening for cystic fibrosis (CF) offers the opportunity for early medical and nutritional intervention that can lead to improved outcomes. Management of the asymptomatic infant diagnosed with CF through newborn screening, prenatal diagnosis, or sibling screening is different from treatment of the symptomatically diagnosed individual. The focus of management is on maintaining health by preventing nutritional and respiratory complications. The CF Foundation convened a committee to develop recommendations based on a systematic review of the evidence and expert opinion. These guidelines encompass monitoring and treatment recommendations for infants diagnosed with CF and are intended to help guide families, primary care providers, and specialty care centers in the care of infants with CF.

Abstract
Pancreatic enzyme supplements (PES) are used in chronic pancreatitis (CP) for correction of pancreatic exocrine insufficiency (PEI) as well as pain and malnutrition. The use of porcine pancreatic enzymes for the correction of exocrine insufficiency is governed by the pathophysiology of the disease as well as pharmacologic properties of PES. Variability in bioequivalence of PES has been noted on in vitro and in vivo testing and has been attributed to the differences in enteric coating and the degree of micro-encapsulation. As a step towards standardizing pancreatic enzyme preparations, the Food and Drug Administration now requires the manufacturers of PES to obtain approval of marketed formulations by April 2010. In patients with treatment failure, apart from evaluating drug and dietary interactions and compliance, physicians should keep in mind that patients may benefit from switching to a different formulation. The choice of PES (enteric coated versus non-enteric coated) and the need for acid suppression should be individualized. There is no current standard test for evaluating adequacy of therapy in CP patients and studies have shown that optimization of therapy based on symptoms may be inadequate. Goals of therapy based on overall patient presentation and specific laboratory tests rather than mere correction of steatorrhea are needed.

Abstract
The two major forms of inflammatory pancreatic diseases, acute and chronic pancreatitis, require different approaches in nutritional management, which are presented in the present guideline. This clinical practice guideline gives evidence-based recommendations for the use of ONS and TF in these patients. It was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was discussed and accepted in a consensus conference. In mild acute pancreatitis enteral nutrition (EN) has no positive impact on the course of disease and is only recommended in patients who cannot consume normal food after 5-7 days. In severe necrotising pancreatitis EN is indicated and should be supplemented by parenteral nutrition if needed. In the majority of patients continuous TF with peptide-based formulae is possible. The jejunal route is recommended if gastric feeding is not tolerated. In chronic pancreatitis more than 80% of patients can be treated adequately with normal food supplemented by pancreatic enzymes. 10-15% of all patients require nutritional supplements, and in approximately 5% tube feeding is indicated.

Abstract
Effective treatment of malabsorption due to severe pancreatic exocrine insufficiency requires delivery of sufficient enzymatic activity into the duodenal lumen simultaneously with meal nutrients. To achieve this, modern therapeutic concepts recommend administration of 25,000 to 40,000 units of lipase per meal using pH-sensitive pancreatin microspheres. In case of treatment failure, dosage should be increased two to three times. If this still is not successful, compliance may be checked by measurement of fecal chymotrypsin, although this is not a standardized procedure. In the compliant patient, diagnosis of pancreatic exocrine insufficiency needs to be reviewed, particularly cases of celiac disease, (concomitant) bacterial overgrowth, and blind loop syndrome, as well as giardiasis, which need to be excluded or otherwise be treated specifically. Finally, additional acid suppression with application of unprotected pancreatin and/or reduced fat intake may help to control malabsorption. Still, in most patients, lipid digestion cannot be completely normalized by current standard therapy. On the one hand, this leads to loss of energy that may only partly be compensated for by increased nutrient intake. On the other hand, increased nutrient exposition of distal intestinal sites may release excessive amounts of mostly inhibitory distal intestinal neurohumoral mediators, and thereby disturb gastrointestinal secretory and motor functions. Consequently, future developments are needed for optimizing treatment.

Abstract
Treatment of steatorrhea by lipase supplementation therapy has become more successful in the last decade due to better understanding of the physiology and pathophysiology of the digestive process. Porcine lipase has been the therapeutic standard for several decades and will continue to be the treatment of choice in pancreatic exocrine insufficiency. Modern therapeutic concepts recommend administration of 25,000-40,000 units of porcine lipase per meal using pH-sensitive pancreatin microspheres. In case of treatment failure, the dose should be increased, compliance should be checked, and other reasons for malabsorption should be excluded. Still, in most patients, lipid digestion cannot be completely normalized by current standard therapy, and future developments are needed for optimizing treatment. In this article, pathophysiologic characteristics of pancreatic exocrine insufficiency, prerequisites for use of alternative lipase sources as well as currently available lipases of nonporcine origin, and new developments are discussed. Current literature suggests that bovine lipase products present a theoretical alternative but play no major role in the western world. Fungal lipase has inferior properties compared with conventional products. Bacterial lipase products show promising potential and offer future therapeutic alternatives. Moreover, human pancreatic lipase gene transfer and application of bioengineered human gastric lipase appear on the horizon.

Abstract
Malabsorption due to severe pancreatic exocrine insufficiency is one of the most important late features of chronic pancreatitis. Generally, steatorrhea is more severe and occurs several years prior to malabsorption of other nutrients because synthesis and secretion of lipase are impaired more rapidly, its intraluminal survival is shorter, and the lack of pancreatic lipase activity is not compensated for by nonpancreatic mechanisms. Patients suffer not only from nutritional deficiencies but also from increased nutrient delivery to distal intestinal sites, causing symptoms by profound alteration of upper gastrointestinal secretory and motor functions. Adequate nutrient absorption requires delivery of sufficient enzymatic activity into the duodenal lumen simultaneously with meal nutrients. The following recommendations are based on modern therapeutic concepts: 25,000 to 40,000 units of lipase per meal using pH-sensitive pancreatin microspheres, with dosage increases, compliance checks, and differential diagnosis in case of treatment failure. Still, in most patients, lipid digestion cannot be completely normalized by current standard therapy, and future developments are needed to optimize treatment.

Abstract
Severe pancreatic exocrine insufficiency leading to malabsorption of nutrients is one of the most important late features of chronic pancreatitis. In contrast to other key enzymes, pancreatic synthesis and secretion of lipase is impaired more rapidly, its intraluminal survival is shorter due to its higher susceptibility against acidic and proteolytic denaturation, and its luminal digestive action is hardly compensated by nonpancreatic mechanisms. As a consequence, steatorrhea is in general more severe and occurs several years before clinical malabsorption of protein or starch. Apart from the detrimental effects of nutrient deficiency, profound alterations of upper gastrointestinal secretory and motor functions may be an additional and hitherto underestimated consequence of increased nutrient delivery to distal intestinal sites. Effective reduction of nutrient malabsorption in pancreatic insufficiency requires delivery of sufficient enzymatic activity into the duodenal lumen simultaneously with meal nutrients. Modern enteric-coated pancreatin microsphere preparations attempt to achieve this by optimizing the size of individual microspheres and chemical properties of the coating. However, lipid digestion cannot be completely normalized in most patients by current standard therapy. In the future, acid and protease stable bacterial and fungal lipases with additional pH optima in the acidic milieu or animal or bioengineered human gastric lipase preparations may offer superior therapeutic alternatives. This review first summarizes current knowledge about secretion and luminal fate of pancreatic enzymes and their effects on nutrient digestion in health and chronic pancreatitis. Second, rationale, current standards, options, and future aspects of enzyme replacement therapy are discussed.

Abstract
OBJECTIVES We compared the nutritional benefits of a protein hydrolysate and a conventional infant formula in infants newly diagnosed with cystic fibrosis (CF). STUDY DESIGN Twenty-three infants with CF (<6 months of age) and pancreatic insufficiency were randomized to receive a hydrolysate formula (Alimentum) or a cow's milk-based formula (Similac). Each patient was monitored at 1 month and then every 3 months for 1 year. RESULTS Eighteen patients (8 Alimentum, 10 Similac) completed the study. At entry, the age distribution and clinical characteristics of each group were comparable. Energy intake with each formula was the same at 1 and 3 months, but at 6 and 12 months the hydrolysate-fed infants had higher age-adjusted energy intake. There were no differences in fecal energy or fecal fat at entry or throughout the study. Although the hydrolysate-fed infants were slightly more malnourished at diagnosis, growth velocity and nutritional status of infants with CF in each group were the same throughout the study. CONCLUSIONS The results of this randomized study fail to support the use of a hydrolyzed formula for the routine care of infants newly diagnosed with CF.

Abstract
BACKGROUND It has been suggested that some of the limitations of the Van de Kamer method for fecal fat measurement could be overcome with the Jeejeebhoy method or the near-infrared reflectance assay. METHODS To test this hypothesis, a fecal fat test was carried out with the three methods, adding butter or MCT oil to the diet of four steatorrhoic patients. An in vitro recovery study of long- and medium-chain triglycerides was also performed. RESULTS The Jeejeebhoy method measured long- and medium-chain fats more accurately than the Van de Kamer method. It found consistently higher steatorrhea values. Mean results of the near-infrared reflectance analysis resembled those of the Van de Kamer method, but with wide discordance of individual data. CONCLUSION The Jeejeebhoy method is more accurate than the Van de Kamer method for fecal fat measurement. The difference may be clinically relevant when most fecal fatty acids derive from medium-chain triglycerides. Near-infrared reflectance may be a viable proposition only when a greater degree of approximation is acceptable.
