The prevalence of malnutrition and fat-soluble vitamin deficiencies in chronic pancreatitis

Nutritional parameters following first episode of pediatric acute pancreatitis

BACKGROUND AND OBJECTIVES

Acute pancreatitis (AP) carries the risk of subsequent nutritional deficiencies. The prevalence of these deficiencies following a single episode of AP in children is unknown. We aimed to determine prevalence of anthropometric and laboratory-based measures of nutritional status in children following their first (index) admission for AP.

METHODS

Prospective observational cohort study of patients ≤21 years of age with first episode of confirmed AP. Anthropometric and laboratory values were obtained at time of AP onset and at follow up time points of 3 and 12 months (m) post AP. AP attack was classified as either: mild, moderately severe or severe (which were combined in one group (SAP)).

RESULTS

181 patients met criteria and were followed prospectively with 52% male, a median age of 13.7 years (IQR 9.4-16.0) and median Body Mass Index (BMI) Z-score of 0.6 (IQR -0.5, 1.6). Most patients had mild AP (140, 77%), with 23% meeting criteria for moderate or severe (41/181). 6 (3%) had diabetes mellitus (DM) predating AP and were excluded from further analysis. BMI Z-score remained stable during the follow up period. 13% of patients developed pre-DM or DM at 3m or 12m. Nearly one third of patients had low ferritin at 3m (29%) or 12m (29%). At 12m, 8% of patients had Vitamin A deficiency. 6% of patients had low Vitamin E levels at 3m and 5% at 12m. Over half of patients at both 3m and 12m had 25 OH Vitamin D insufficiency or deficiency (56% and 56%). Prolonged International Normalized Ratio (INR) (>1.3) was seen in 9% of patients at 12m. Very low albumin (<3.5 g/dL) was found in 24% of patients at 3m and 18% at 12m (Table 1). Patients with very low albumin at 3m were younger (median 10.7 vs. 14.2 years, p = 0.04), however sex, BMI Z-score and AP severity were not associated with albumin level. Although BMI Z-score did not differ between the groups, those with SAP had a significant decrease in BMI Z-score from first attack compared to mild AP at 3m (-0.4 vs. 0.0, p = 0.0002, Figure 2). At 3m, Vitamin E deficiency in SAP versus mild AP was found in 20% vs 2% (p = 0.04) and SAP had a lower median hematocrit (35.8 vs. 37.6, p = 0.046). There were no other laboratory significant differences at 3m in mild versus SAP groups. At 12m, those with SAP were more likely to have pre-DM or DM compared to mild AP (31% vs. 7%, p = 0.002). No other significant laboratory differences occurred at 12m.

CONCLUSIONS

After the first AP attack patients experience nutritional deficiencies, including ferritin, all fat-soluble vitamins, and low albumin. SAP is associated with a decrease in BMI Z-score, increased prevalence of vitamin E deficiency at 3m, and an increase in pre-diabetes and diabetes at 12m. Serial monitoring of vitamin and mineral values post AP is warranted and further prospective studies are needed.

Levels of retinol and retinoic acid in pancreatic cancer, type-2 diabetes and chronic pancreatitis

AIMS

Retinoids participate in multiple key processes in the human body e.g., vision, cell differentiation and embryonic development. There is growing evidence of the relationship between retinol, its active metabolite- all-trans retinoic acid (ATRA) - and several pancreatic disorders. Although low levels of ATRA in pancreatic ductal adenocarcinoma (PDAC) tissue have been reported, data on serum levels of ATRA in PDAC is still limited. The aim of our work was to determine serum concentrations of retinol and ATRA in patients with PDAC, type-2 diabetes mellitus (T2DM), chronic pancreatitis (CHP) and healthy controls.

METHODS

High performance liquid chromatography with UV detection (HPLC) was used to measure serum levels of retinol and ATRA in 246 patients with different stages of PDAC, T2DM, CHP and healthy controls.

RESULTS

We found a significant decrease in the retinol concentration in PDAC (0.44+/-0.18 mg/L) compared to T2DM (0.65+/-0.19 mg/L, P<0.001), CHP (0.60+/-0.18 mg/L, P< 0.001) and healthy controls (0.61+/-0.15 mg/L, P<0.001), significant decrease of ATRA levels in PDAC (1.14+/-0.49 ug/L) compared to T2DM (1.37+/-0.56 ug/L, P<0.001) and healthy controls(1.43+/-0.55 ug/L, P<0.001). Differences between early stages (I+II) of PDAC and non-carcinoma groups were not significant. We describe correlations between retinol, prealbumin and transferrin, and correlation of ATRA and IGFBP-2.

CONCLUSION

Significant decrease in retinol and ATRA levels in PDAC compared to T2DM, healthy individuals and/or CHP supports existing evidence of the role of retinoids in PDAC. However, neither ATRA nor retinol are suitable for detection of early PDAC. Correlation of ATRA levels and IGFBP-2 provides new information about a possible IGF and retinol relationship.

Nutrition challenges following total pancreatectomy with islet autotransplantation

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. The postoperative phase can be complicated by gastrointestinal symptoms causing patients to have difficulty regaining adequate oral intake. Enteral nutrition is frequently provided as a bridge to oral diet. Patients undergoing TPIAT must be monitored for macronutrient and micronutrient deficiencies following the procedure. Exocrine insufficiency must be treated lifelong with pancreatic enzyme replacement therapy. Endocrine function must be monitored and exogenous insulin provided in the postoperative phase; however, a majority of patients undergoing TPIAT require little or no long-term insulin. Although TPIAT can be a successful option for patients with chronic pancreatitis, nutrition-related concerns must be addressed for optimal recovery.

Fat-soluble vitamin deficiency and exocrine pancreatic insufficiency among adults with chronic pancreatitis: Is routine monitoring necessary for all patients?

Chronic pancreatitis (CP) is often associated with exocrine pancreatic insufficiency (EPI), which may increase risk for fat-soluble vitamin depletion. Although vitamin D deficiency is widespread among the general population, vitamins A, E, and K deficiencies may more uniquely present in patients with CP. Yet, it is unclear whether fat-soluble vitamin status should be routinely monitored in all patients with CP or limited to those with EPI. The purpose of this review is to describe the laboratory status of vitamins A, E, and K in adult patients with CP and their association with exocrine pancreatic function. Five primary, observational studies met the inclusion criteria for qualitative synthesis. Biochemical deficiencies in fat-soluble vitamins were observed across trials but results varied with respect to whether EPI increased risk. Challenges related to the diagnosis and treatment of EPI along with potential confounders may contribute to the heterogeneity among study results. Although more studies are needed to determine the influence of pancreatic enzyme replacement therapy on fat-soluble vitamin status as well as effective vitamin repletion strategies, clinicians should consider periodically screening for deficiencies in all patients with CP regardless of EPI to avoid associated health effects of vitamin depletion.

ESPEN practical guideline on clinical nutrition in acute and chronic pancreatitis

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.

Managing complications of chronic pancreatitis: a guide for the gastroenterologist

INTRODUCTION

Chronic pancreatitis is a heterogeneous and complex syndrome that, in most cases, causes pain as a cardinal symptom and affects both the morphology and function of the pancreas, leading to several serious complications.

AREAS COVERED

The present review, based on a non-systematic PubMed search updated to June 2023, aims to present the current available evidence on the role of gastroenterologists in the diagnosis and treatment of both local and systemic complications by either endoscopic or medical treatments.

EXPERT OPINION

At diagnosis and during chronic pancreatitis follow-up, particular care is needed to consider not only the clinically manifest signs and symptoms of the disease, such as pain, jaundice, gastrointestinal obstruction, and pseudocysts, which require multidisciplinary discussion to establish the best treatment option (endoscopic or surgical), but also less evident systemic complications. Pancreatic exocrine and endocrine insufficiency, together with chronic inflammation, addiction, and dysbiosis, contribute to malnutrition, sarcopenia, and osteopathy. These complications, in turn, increase the risk of infection, thromboembolic events, and death. Patients with chronic pancreatitis also have an increased risk of psychiatric disorders and pancreatic cancer onset. Overall, patients with chronic pancreatitis should receive a holistic evaluation, considering all these aspects, possibly through multidisciplinary care in dedicated expert centers.

AGA Clinical Practice Update on the Epidemiology, Evaluation, and Management of Exocrine Pancreatic Insufficiency: Expert Review

DESCRIPTION

Exocrine pancreatic insufficiency (EPI) is a disorder caused by the failure of the pancreas to deliver a minimum/threshold level of specific pancreatic digestive enzymes to the intestine, leading to the maldigestion of nutrients and macronutrients, resulting in their variable deficiencies. EPI is frequently underdiagnosed and, as a result, patients are often not treated appropriately. There is an urgent need to increase awareness of and treatment for this condition. The aim of this American Gastroenterological Association (AGA) Clinical Practice Update Expert Review was to provide Best Practice Advice on the epidemiology, evaluation, and management of EPI.

METHODS

This Expert Review was commissioned and approved by the American Gastroenterological Association (AGA) Institute Clinical Practice Updates Committee (CPUC) and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership, and underwent internal peer review by the CPUC and external peer review through standard procedures of Gastroenterology. These Best Practice Advice statements were drawn from a review of the published literature and from expert opinion. Because systematic reviews were not performed, these Best Practice Advice statements do not carry formal ratings regarding the quality of evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: EPI should be suspected in patients with high-risk clinical conditions, such as chronic pancreatitis, relapsing acute pancreatitis, pancreatic ductal adenocarcinoma, cystic fibrosis, and previous pancreatic surgery. BEST PRACTICE ADVICE 2: EPI should be considered in patients with moderate-risk clinical conditions, such as duodenal diseases, including celiac and Crohn's disease; previous intestinal surgery; longstanding diabetes mellitus; and hypersecretory states (eg, Zollinger-Ellison syndrome). BEST PRACTICE ADVICE 3: Clinical features of EPI include steatorrhea with or without diarrhea, weight loss, bloating, excessive flatulence, fat-soluble vitamin deficiencies, and protein-calorie malnutrition. BEST PRACTICE ADVICE 4: Fecal elastase test is the most appropriate initial test and must be performed on a semi-solid or solid stool specimen. A fecal elastase level <100 μg/g of stool provides good evidence of EPI, and levels of 100-200 μg/g are indeterminate for EPI. BEST PRACTICE ADVICE 5: Fecal elastase testing can be performed while on pancreatic enzyme replacement therapy. BEST PRACTICE ADVICE 6: Fecal fat testing is rarely needed and must be performed when on a high-fat diet. Quantitative testing is generally not practical for routine clinical use. BEST PRACTICE ADVICE 7: Response to a therapeutic trial of pancreatic enzymes is unreliable for EPI diagnosis. BEST PRACTICE ADVICE 8: Cross-sectional imaging methods (computed tomography scan, magnetic resonance imaging, and endoscopic ultrasound) cannot identify EPI, although they play an important role in the diagnosis of benign and malignant pancreatic disease. BEST PRACTICE ADVICE 9: Breath tests and direct pancreatic function tests hold promise, but are not widely available in the United States. BEST PRACTICE ADVICE 10: Once EPI is diagnosed, treatment with pancreatic enzyme replacement therapy (PERT) is required. If EPI is left untreated, it will result in complications related to fat malabsorption and malnutrition, having a negative impact on quality of life. BEST PRACTICE ADVICE 11: PERT formulations are all derived from porcine sources and are equally effective at equivalent doses. There is a need for H2 or proton pump inhibitor therapy with non-enteric-coated preparations. BEST PRACTICE ADVICE 12: PERT should be taken during the meal, with the initial treatment of at least 40,000 USP units of lipase during each meal in adults and one-half of that with snacks. The subsequent dosage can be adjusted based on the meal size and fat content. BEST PRACTICE ADVICE 13: Routine supplementation and monitoring of fat-soluble vitamin levels are appropriate. Dietary modifications include a low-moderate fat diet with frequent smaller meals and avoiding very-low-fat diets. BEST PRACTICE ADVICE 14: Measures of successful treatment with PERT include reduction in steatorrhea and associated gastrointestinal symptoms; a gain of weight, muscle mass, and muscle function; and improvement in fat-soluble vitamin levels. BEST PRACTICE ADVICE 15: EPI should be monitored and baseline measurements of nutritional status should be obtained (body mass index, quality-of-life measure, and fat-soluble vitamin levels). A baseline dual-energy x-ray absorptiometry scan should be obtained and repeated every 1-2 years.

Bone health in children with recurrent and chronic pancreatitis: A multi-center cross sectional analysis

BACKGROUND/OBJECTIVES

Bone health of children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) is not well studied.

METHODS

This retrospective study was performed at three sites and included data from INSPPIRE-2.

RESULTS

Of the 87 children in the study: 46 had ARP (53%), 41 had CP (47%). Mean age was 13.6 ± 3.9 years at last DXA scan. The prevalence of low height-for-age (Z-score < -2) (13%, 10/78) and low bone mineral density (BMD) adjusted for height (Z-score < -2) (6.4%, 5/78) were higher than a healthy reference sample (2.5%, p < 0.0001 and p = 0.03, respectively).

CONCLUSION

Children with ARP or CP have lower height and BMD than healthy peers. Attention to deficits in growth and bone mineral accrual in children with pancreatic disease is warranted.

Nutritional Risks in Patients Undergoing Total Pancreatectomy Islet AutoTransplantation in the POST Consortium

BACKGROUND AND AIMS

Total pancreatectomy with islet autotransplantation (TPIAT) can relieve pain for individuals with acute recurrent or chronic pancreatitis. However, TPIAT may increase the risk of poor nutritional status with complete exocrine pancreatic insufficiency, partial duodenectomy, and intestinal reconstruction. Our study's objective was to evaluate nutritional status, anthropometrics, and vitamin levels before and after TPIAT.

METHODS

The multicenter Prospective Observational Study of TPIAT (POST) collects measures including vitamins A, D, and E levels, pancreatic enzyme dose, and multivitamin (MVI) administration before and 1-year after TPIAT. Using these data, we studied nutritional and vitamin status before and after TPIAT.

RESULTS

348 TPIAT recipients were included (68% adult, 37% male, 93% Caucasian). In paired analyses at 1-year follow-up, vitamin A was low in 23% (vs 9% pre-TPIAT, p < 0.001); vitamin E was low in 11% (vs 5% pre-TPIAT, p = 0.066), and 19% had vitamin D deficiency (vs 12% pre-TPIAT, p = 0.035). Taking a fat-soluble multivitamin (pancreatic MVI) was associated with lower risk for vitamin D deficiency (p = 0.002). Adults were less likely to be on a pancreatic MVI at follow-up (34% vs 66% respectively, p < 0.001). Enzyme dosing was adequate. More adults versus children were overweight or underweight pre- and post-TPIAT. Underweight status was associated with vitamin A (p = 0.014) and E (p = 0.02) deficiency at follow-up.

CONCLUSIONS

Prevalence of fat-soluble vitamin deficiencies increased after TPIAT, especially if underweight. We strongly advocate that all TPIAT recipients have close post-operative nutritional monitoring, including vitamin levels. Pancreatic MVIs should be given to minimize risk of developing deficiencies.

Practical guideline on obesity care in patients with gastrointestinal and liver diseases - Joint ESPEN/UEG guideline

BACKGROUND

Patients with chronic gastrointestinal disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean gastrointestinal patients. The present guideline addresses this question according to current knowledge and evidence.

OBJECTIVE

The present practical guideline is intended for clinicians and practitioners in general medicine, gastroenterology, surgery and other obesity management, including dietitians and focuses on obesity care in patients with chronic gastrointestinal diseases.

METHODS

The present practical guideline is the shortened version of a previously published scientific guideline developed according to the standard operating procedure for ESPEN guidelines. The content has been re-structured and transformed into flow-charts that allow a quick navigation through the text.

RESULTS

In 100 recommendations (3× A, 33× B, 24 × 0, 40× GPP, all with a consensus grade of 90% or more) care of gastrointestinal patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially metabolic associated liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician.

CONCLUSION

The present practical guideline offers in a condensed way evidence-based advice how to care for patients with chronic gastrointestinal diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

Pediatric-to-Adult Transfer of Care in Patients With Pancreas Disease: Recommendations for Care and Research Opportunities

Young adults who have experienced recurrent acute pancreatitis and chronic pancreatitis as children or adolescents are vulnerable to poor follow-up and disease management during the transfer from the pediatric to adult healthcare system. Although formalized transition programs for young adults have been developed and described for other disease conditions, no such program has been described for young adults with pancreatic disease. This document is the first expert opinion outlining the important aspects of a transitional care and transfer program tailored to youth with recurrent acute and chronic pancreatitis. We emphasize the unique needs of these patients as they transfer to adult health care and the need for further research. The goal of improved transitional care and transfer is to enhance the services provided to adolescents/young adults with pancreatic disease in both healthcare settings and improve continuity of follow-up care.

Utility of Fecal Elastase-1 to diagnose severe exocrine insufficiency in chronic pancreatitis: Real world experience

INTRODUCTION

Quantitative fecal fat estimation is the gold standard test to diagnose steatorrhea (fecal fat >7 g/day) in chronic pancreatitis (CP), but cumbersome and inconvenient. So, fecal elastase-1 (FE) is proposed as a good alternative but the data on the diagnostic utility of FE to diagnose steatorrhea is variable.

METHODS

This retrospective study included adult CP patients evaluated with both 24-h fecal-fat and FE tests within a 3-month period. The objective was to evaluate the diagnostic performance of FE to diagnose steatorrhea and to evaluate the FE progression over 9-month period.

RESULTS

Among the 147 included patients, the frequency of steatorrhea (fecal fat >7 g/day) was 34%. The sensitivity, specificity, and negative likelihood ratio (LR) of FE was 90%, 28.9% and 0.35 at cut-off of <100 μg/g stool to diagnose steatorrhea; and 96%, 11.3% and 0.35 at cut-off of <200 μg/g stool, respectively. The optimal cut-off of FE was <20 on receiver operating characteristic curve (sensitivity 66%; specificity 69%; positive LR 2.14). There was no statistically significant variation in FE levels over 9 months interval among a hundred patients.

CONCLUSION

Compared to FE ≥ 200 μg/g stool, FE ≥ 100 can used to exclude steatorrhea (better specificity and negative LR). FE < 20 alone cannot replace fecal fat estimation to confirm steatorrhea but to be interpreted with clinical features. Repeat FE testing for exocrine insufficiency progression can be done at least a year later.

Predictive Risk Factors of Pancreatic Exocrine Insufficiency Developed After Acute Pancreatitis: A Retrospective Cohort Study

Purpose

The aim of this study was to compare the clinical characteristics of acute pancreatitis (AP) patients between those who developed pancreatic exocrine insufficiency (PEI) and those who did not, and to investigate the predictive factors of PEI.

Patients and Methods

From October 1st 2019 to July 30th 2021, AP patients admitted at our center were included. The fecal elastase-1 assay was adopted for PEI diagnosis. The clinical characteristics, treatments, and outcomes between the patients with and without PEI were analyzed.

Results

In total, 63 males and 42 females were included. There were 27 patients with mild AP, 54 with moderately severe AP, and 24 with severe AP. The median modified computed tomography severity index (MCTSI) was 6.000(4.000, 8.000). During the follow-up, 38 patients developed PEI after AP. The univariate analysis showed that higher ASA grade (P = 0.006), more severe AP (P = 0.000), the presence of multiple organ dysfunction syndrome (P = 0.030), higher MCTSI (P = 0.000), the development of infected pancreatic necrosis (P = 0.002) and local complications (P = 0.000), higher levels of triacylglycerol (P = 0.022), video-assisted retroperitoneal debridement intervention (P = 0.015), and longer intensive care unit stay (P = 0.044) were correlated with PEI development. Furthermore, the logistic regression analyses showed that MCTSI during hospitalization is an independent risk factor for PEI development during the AP recovery period.

Conclusion

ASA grade, severity of AP, multiple organ dysfunction syndrome, MCTSI, infected pancreatic necrosis, local complications, higher levels of triacylglycerol, video-assisted retroperitoneal debridement intervention, and longer intensive care unit stay were potentially associated with PEI development during the AP recovery period. High MCTSI was independently associated with the development of PEI during the AP recovery period, which may help alert to the possibility of PEI to help with its early detection and treatment.

Impact of Sarcopenia on Patients with Localized Pancreatic Ductal Adenocarcinoma Receiving FOLFIRINOX or Gemcitabine as Adjuvant Chemotherapy

Background: Despite its toxicity, modified FOLFIRINOX is the main chemotherapy for localized, operable pancreatic adenocarcinomas. Sarcopenia is known as a factor in lower overall survival (OS). The purpose of this study was to assess the impact of sarcopenia on OS in patients with localized pancreatic ductal adenocarcinoma (PDAC) who received modified FOLFIRINOX or gemcitabine as adjuvant chemotherapy. Methods: Patients with operated PDAC who received gemcitabine-based (GEM group) or oxaliplatin-based (OXA group) adjuvant chemotherapy between 2008 and 2021 were retrospectively included. Sarcopenia was estimated on a baseline computed tomography (CT) examination using the skeletal muscular index (SMI). The primary evaluation criterion was OS. Secondary evaluation criteria were disease-free survival (DFS) and toxicity. Results: Seventy patients treated with gemcitabine-based (n = 49) and oxaliplatin-based (n = 21) chemotherapy were included, with a total of fifteen sarcopenic patients (eight in the GEM group and seven in the OXA group). The median OS was shorter in sarcopenic patients (25 months) compared to non-sarcopenic patients (158 months) (p = 0.01). A longer OS was observed in GEM non-sarcopenic patients (158 months) compared to OXA sarcopenic patients (14.4 months) (p < 0.01). The median OS was 157.7 months in the GEM group vs. 34.1 months in the OXA group (p = 0.13). No differences in median DFS were found between the GEM group and OXA group. More toxicity events were observed in the OXA group (50%) than in the GEM group (10%), including vomiting (p = 0.02), mucositis (p = 0.01) and neuropathy (p = 0.01). Conclusion: Sarcopenia is associated with a worse prognosis in patients with localized operated PDAC whatever the delivered adjuvant chemotherapy.

Progressive reduction in circulating levels of carotenoids and other micronutrients in patients with chronic pancreatitis

BACKGROUND

Although micronutrients modulate immunity and inflammation, it remains elusive whether they are implicated in the development and progression of chronic pancreatitis (CP). This study aimed to investigate differences in the circulating levels of selected carotenoids and vitamins between CP and controls and trends in the levels of these micronutrients across controls, early CP, and definite CP.

METHODS

Demographic and lifestyle data were extracted from medical records for 53 patients with CP (13 early and 38 definite) and obtained using a questionnaire for 52 controls. Plasma β-carotene, lycopene, cryptoxanthin, zeaxanthin, and α-tocopherol and serum 25(OH)D, folate, IL-6, TNF-α, and MCP-1 were measured with state-of-the-art methods.

RESULTS

The levels of all micronutrients (except folate) were significantly lower in CP than in controls. There was a progressive decrease in the levels of these micronutrients across controls, early CP, and definite CP (all p values for trend: ≤0.0012); e.g., plasma lycopene was 36.6, 21.5, and 14.5 μg/dL for controls, early CP, and definite CP, respectively. After adjustment for confounders, there were strong, inverse associations between the levels of all micronutrients (except folate) and CP (e.g., OR (95% CI) for ≥ median vs. <median: 0.10 (0.04, 0.27) for lycopene, 0.15 (0.05, 0.38) for α-tocopherol, and 0.24 (0.09, 0.64) for 25(OH)D). These associations became weaker after additional adjustment for inflammation markers (IL-6, TNF-α, and MCP-1).

CONCLUSIONS

The circulating levels of some carotenoids, α-tocopherol, and vitamin D were reduced in CP patients compared with controls and this reduction was more pronounced in definite CP than in early CP.

AGA-PancreasFest Joint Symposium on Exocrine Pancreatic Insufficiency

Exocrine pancreatic insufficiency (EPI) is a clinically defined syndrome based on the physician's assessment of a patient's maldigestion. However, current clinical definitions are inadequate in determining (1) the threshold of reduced pancreatic digestive enzyme secretion that determines "pancreatic insufficiency" in an individual patient; (2) the role of pancreatic function tests; (3) effects of differing metabolic needs, nutrition intake, and intestinal function/adaptation (4) when pancreatic enzyme replacement therapy is needed; and (5) how to monitor and titrate multiple therapies. Experts and key opinion leaders were invited to PancreasFest 2021 to discuss and help clarify mechanistic issues critical to defining EPI and to address misconceptions and barriers limiting advancements in patient care. Clinically EPI is defined as inadequate delivery of pancreatic digestive enzymes to meals to meet nutritional needs and is reversed with appropriate treatment. A new mechanistic definition of EPI was proposed that includes the disorders essence and character: (1) EPI is a disorder caused by failure of the pancreas to deliver a minimum/threshold level of specific pancreatic digestive enzymes to the intestine in concert with ingested nutrients, followed by enzymatic digestion of a series of individual snacks and meals over time to meet nutritional and metabolic needs, given (a) the specific macronutritional and micronutritional needs; (b) nutrient intake; (c) exocrine pancreatic function; and (d) intestinal anatomy, function, diseases, and adaptative capacity. (2) EPI is characterized by variable deficiencies in micronutrients and macronutrients, especially essential fats and fat-soluble vitamins, by gastrointestinal symptoms of nutrient maldigestion and by improvement or correction of nutritional state with lifestyle changes, disease treatment, optimized diet, dietary supplements, and/or administration of adequate pancreatic enzyme replacement therapy. EPI is complex and individualized and multidisciplinary approaches are needed to optimize therapy. Better pancreas function tests and biomarkers are needed to diagnose EPI and guide treatment.

Nutritional Support in Pancreatic Diseases

This review summarizes the main pancreatic diseases from a nutritional approach. Nutrition is a cornerstone of pancreatic disease and is sometimes undervalued. An early identification of malnutrition is the first step in maintaining an adequate nutritional status in acute pancreatitis, chronic pancreatitis and pancreatic cancer. Following a proper diet is a pillar in the treatment of pancreatic diseases and, often, nutritional counseling becomes essential. In addition, some patients will require oral nutritional supplements and fat-soluble vitamins to combat certain deficiencies. Other patients will require enteral nutrition by nasoenteric tube or total parenteral nutrition in order to maintain the requirements, depending on the pathology and its consequences. Pancreatic exocrine insufficiency, defined as a significant decrease in pancreatic enzymes or bicarbonate until the digestive function is impaired, is common in pancreatic diseases and is the main cause of malnutrition. Pancreatic enzymes therapy allows for the management of these patients. Nutrition can improve the nutritional status and quality of life of these patients and may even improve life expectancy in patients with pancreatic cancer. For this reason, nutrition must maintain the importance it deserves.

Optimizing nutrition in chronic pancreatitis

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.

European guideline on obesity care in patients with gastrointestinal and liver diseases - Joint European Society for Clinical Nutrition and Metabolism / United European Gastroenterology guideline

BACKGROUND

Patients with chronic gastrointestinal (GI) disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean GI patients. The present guideline addresses this question according to current knowledge and evidence.

OBJECTIVE

The objective of the guideline is to give advice to all professionals working in the field of gastroenterology care including physicians, surgeons, dietitians and others how to handle patients with GI disease and obesity.

METHODS

The present guideline was developed according to the standard operating procedure for European Society for Clinical Nutrition and Metabolism guidelines, following the Scottish Intercollegiate Guidelines Network grading system (A, B, 0, and good practice point [GPP]). The procedure included an online voting (Delphi) and a final consensus conference.

RESULTS

In 100 recommendations (3x A, 33x B, 24x 0, 40x GPP, all with a consensus grade of 90% or more) care of GI patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially fatty liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician.

CONCLUSION

The present guideline offers for the first time evidence-based advice how to care for patients with chronic GI diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

European guideline on obesity care in patients with gastrointestinal and liver diseases - Joint ESPEN/UEG guideline

BACKGROUND

Patients with chronic gastrointestinal (GI) disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean GI patients. The present guideline addresses this question according to current knowledge and evidence.

OBJECTIVE

The objective of the guideline is to give advice to all professionals working in the field of gastroenterology care including physicians, surgeons, dietitians and others how to handle patients with GI disease and obesity.

METHODS

The present guideline was developed according to the standard operating procedure for ESPEN guidelines, following the Scottish Intercollegiate Guidelines Network (SIGN) grading system (A, B, 0, and good practice point (GPP)). The procedure included an online voting (Delphi) and a final consensus conference.

RESULTS

In 100 recommendations (3x A, 33x B, 24x 0, 40x GPP, all with a consensus grade of 90% or more) care of GI patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially fatty liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician.

CONCLUSION

The present guideline offers for the first time evidence-based advice how to care for patients with chronic GI diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

Complications of chronic pancreatitis prior to and following surgical treatment: A proposal for classification

BACKGROUND

Chronic pancreatitis (CP) is a long-lasting disease frequently associated with complications for which there is no comprehensive pathophysiological classification.

AIM

The aims of this study were to: Propose a pathophysiological classification of the complications of CP; evaluate their prevalence in a surgical cohort prior to, and following surgical management; and assess the impact of the surgical treatment on the occurrence of new complications of CP during follow-up. We hypothesized that optimal surgical treatment can resolve existing complications and reduce the risk of new complications, with the exclusion of pancreatic insufficiency. The primary outcomes were prevalence of complications of CP at baseline (prior to surgical treatment) and occurrence of new complications during follow-up.

METHODS

After institutional review board approval, a prospective observational cohort study with long-term follow-up (up to 20.4 years) was conducted. All consecutive single-center adult patients (≥ 18 years of age) with CP according to the criteria of the American Pancreas Association subjected to surgical management between 1997 and 2021, were included. The prevalence of CP complications evaluated, according to the proposed classification, in a surgical cohort of 166 patients. Development of the pathophysiological classification was based on a literature review on the clinical presentation, course, and complications of CP, as well a review of previous classification systems of CP.

RESULTS

We distinguished four groups of complications: Pancreatic duct complications, peripancreatic complications, pancreatic hemorrhages, and pancreatic insufficiency (exocrine and endocrine). Their baseline prevalence was 20.5%, 23.5%, 10.2%, 31.3%, and 27.1%, respectively. Surgical treatment was highly effective in avoiding new complications in the first and third groups. In the group of peripancreatic complications, the 15-year Kaplan-Meier prevalence of new complications was 12.1%. The prevalence of pancreatic exocrine and endocrine insufficiency increased during follow-up, being 66.4% and 47.1%, respectively, at 15 years following surgery. Pancreatoduodenal resection resulted optimal results in avoiding new peripancreatic complications, but was associated with the highest rate of pancreatic exocrine insufficiency.

CONCLUSION

The proposed complication classification improves the understanding of CP. It could be beneficial for clinical decision making, as it provides an opportunity for more comprehensive judgement on patient’s needs on the one hand, and on the pros and cons of the treatment under consideration, on the other. The presence of complications of CP and the risk of development of new ones should be among the main determinants of surgical choice.

Physical activity for chronic pancreatitis: a systematic review

BACKGROUND

Chronic pancreatitis (CP) is a progressive inflammatory disorder of the pancreas. Sarcopenia is a degenerative loss of skeletal muscle mass, quality, and strength and is commonly associated with chronic pancreatitis. Regular physical activity and adequate functional fitness have been found to ameliorate the risk and effects of sarcopenia in other chronic diseases. The objective of this systematic review was to collate all the published evidence which has examined any type of physical activity as an intervention in the chronic pancreatitis patient population.

METHODS

This systematic review was conducted in accordance with the PRISMA guidelines. The search strategy was designed by the medical librarian (DM) for Embase and then modified for the other search platforms. Two of the researchers (BM) and (AM) then performed the literature search using the databases Embase, Medline, CINAHL, and Web of Science.

RESULTS

An electronic identified a total of 571 references imported to Covidence as 420 when the duplicates (151) were removed. 420 titles were screened and 390 were removed as not relevant from their titles. 30 full text papers were selected and from these, only one full text paper was deemed suitable for inclusion.

CONCLUSIONS

There is currently insufficient evidence to advise physical activity in the chronic pancreatitis population. However, given the evidence to support physical activity in many other chronic diseases this review highlights the need for urgent investigation of physical activity as an intervention on this specific patient population.

Vitamin D: A Potential Star for Treating Chronic Pancreatitis

Chronic pancreatitis (CP) is a chronic inflammatory and fibrotic disease of the pancreas. The incidence of CP is increasing worldwide but the effective therapies are lacking. Hence, it is necessary to identify economical and effective agents for the treatment of CP patients. Vitamin D (VD) and its analogues have been confirmed as pleiotropic regulators of cell proliferation, apoptosis, differentiation and autophagy. Clinical studies show that VD deficiency is prevalent in CP patients. However, the correlation between VD level and the risk of CP remains controversial. VD and its analogues have been demonstrated to inhibit pancreatic fibrosis by suppressing the activation of pancreatic stellate cells and the production of extracellular matrix. Limited clinical trials have shown that the supplement of VD can improve VD deficiency in patients with CP, suggesting a potential therapeutic value of VD in CP. However, the mechanisms by which VD and its analogues inhibit pancreatic fibrosis have not been fully elucidated. We are reviewing the current literature concerning the risk factors for developing CP, prevalence of VD deficiency in CP, mechanisms of VD action in PSC-mediated fibrogenesis during the development of CP and potential therapeutic applications of VD and its analogues in the treatment of CP.

Malnutrition Is Highly Prevalent in Patients With Chronic Pancreatitis and Characterized by Loss of Skeletal Muscle Mass but Absence of Impaired Physical Function

Background/Aims

Patients with chronic pancreatitis (CP) have an increased risk of malnutrition, a condition linked to reduced muscle mass and physical performance. We have investigated the risk factors, phenotypic presentation, and health implications associated with malnutrition in CP.

Materials and Methods

In a multicenter cross-sectional study we recruited patients with confirmed CP and healthy volunteers as a control group. Malnutrition was diagnosed according to the criteria proposed by the Global Leadership Initiative on Malnutrition. We performed detailed examinations of body composition and physical function as well as testing of routine blood parameters and markers of inflammation.

Results

We included 66 patients [mean (±SD) age: 56.0 (±14.5) years; 51 males] and an equal number of age- and sex-matched controls. Moderate malnutrition was diagnosed in 21% (n = 14) and severe malnutrition in 42% (n = 28) of patients. Besides weight loss malnourished patients showed lower fat and skeletal muscle mass compared to both non-malnourished subjects and healthy controls. Only in severe malnutrition, blood parameters reflected elevated inflammation and reduced muscle reserves. Handgrip strength in patients did not differ by nutritional status but there was a significant correlation (rho = 0.705, p < 0.001) with skeletal muscle mass. Although 20 patients (30%) had pathologically reduced skeletal muscle mass, only two individuals (3%) had sarcopenia with concomitantly reduced handgrip strength.

Conclusion

Malnutrition is a frequent complication of CP characterized by loss of skeletal muscle mass. As this condition becomes evident only at an advanced stage, regular testing for altered body composition is recommended. Suitable biomarkers and the link between loss of muscle mass and physical function require further investigation.

Vitamin D and Pancreatitis: A Narrative Review of Current Evidence

Emerging research indicates that vitamin D metabolic disorder plays a major role in both acute pancreatitis (AP) and chronic pancreatitis (CP). This has been demonstrated by studies showing that vitamin D deficiency is associated with pancreatitis and its anti-inflammatory and anti-fibrotic effects by binding with the vitamin D receptor (VDR). However, the role of vitamin D assessment and its management in pancreatitis remains poorly understood. In this narrative review, we discuss the recent advances in our understanding of the molecular mechanisms involved in vitamin D/VDR signaling in pancreatic cells; the evidence from observational studies and clinical trials that demonstrate the connection among vitamin D, pancreatitis and pancreatitis-related complications; and the route of administration of vitamin D supplementation in clinical practice. Although further research is still required to establish the protective role of vitamin D and its application in disease, evaluation of vitamin D levels and its supplementation should be important strategies for pancreatitis management according to currently available evidence.

Diagnosis and treatment of exocrine pancreatic insufficiency in chronic pancreatitis: An international expert survey and case vignette study

INTRODUCTION

Despite evidence-based guidelines, exocrine pancreatic insufficiency is frequently underdiagnosed and undertreated in patients with chronic pancreatitis. Therefore, the aim of this study is to provide insight into the current opinion and clinical decision-making of international pancreatologists regarding the management of exocrine pancreatic insufficiency.

METHODS

An online survey and case vignette study was sent to experts in chronic pancreatitis and members of various pancreatic associations: EPC, E-AHPBA and DPSG. Experts were selected based on publication record from the past 5 years.

RESULTS

Overall, 252 pancreatologists participated of whom 44% had ≥ 15 years of experience and 35% treated ≥ 50 patients with chronic pancreatitis per year. Screening for exocrine pancreatic insufficiency as part of the diagnostic work-up for chronic pancreatitis is performed by 69% and repeated annually by 21%. About 74% considers nutritional assessment to be part of the standard work-up. Patients are most frequently screened for deficiencies of calcium (47%), iron (42%), vitamin D (61%) and albumin (59%). In case of clinically steatorrhea, 71% prescribes enzyme supplementation. Of all pancreatologists, 40% refers more than half of their patients to a dietician. Despite existing guidelines, 97% supports the need for more specific and tailored instructions regarding the management of exocrine pancreatic insufficiency.

CONCLUSION

This survey identified a lack of consensus and substantial practice variation among international pancreatologists regarding guidelines pertaining the management of exocrine pancreatic insufficiency. These results highlight the need for further adaptation of these guidelines according to current expert opinion and the level of available scientific evidence.

Exocrine pancreas insufficiency in chronic pancreatitis - Risk factors and associations with complications. A multicentre study of 1869 patients

BACKGROUND/OBJECTIVES

There is scarce information about risk factors for exocrine pancreas insufficiency (EPI) in chronic pancreatitis (CP), and how it associates with other complications. The aim of the present study was to examine risk factors for EPI and associations to procedures and other CP related complications in a large, Northern European cohort.

PATIENTS AND METHODS

We retrieved cross-sectional data on demographics, status on EPI, aetiological risk factors for CP, CP related complications as well as surgical and endoscopic treatment from the Scandinavian Baltic Pancreatic Club Database. Associations were assessed by univariate and multivariate logistic regression analyses. Results are presented as odds ratios (OR) with 95% confidence intervals.

RESULTS

We included 1869 patients with probable or definitive CP in the study. Exocrine pancreas insufficiency was present in 849 (45.4%) of patients. In multivariate analyses, EPI associated with smoking aetiology (OR 1.47 (1.20-1.79), p < 0.001), and nutritional/metabolic aetiology (OR 0.52 (0.31-0.87), p = 0.01) to CP. Pancreatic or common bile duct stenting procedure and pancreatic resection were both associated with EPI (ORs 1.44 (1.15-1.80), p = 0.002 and 1.54 (1.02-2.33), p = 0.04, respectively). The presence of diabetes mellitus (OR 2.45 (1.92-3.15), p < 0.001), bile duct stenosis (OR 1.48 (1.09-2.00), p = 0.02) and underweight (2.05 (OR 1.40-3.02), p < 0.001) were all associated with presence of EPI.

CONCLUSIONS

Smoking, bile duct stenosis, previous stenting and resection procedures are all associated with EPI in patients with CP. Presence of EPI were also associated with malnutrition and diabetes mellitus. Hence, intensive nutritional surveillance is needed in these patients.

Malnutrition by GLIM criteria in chronic pancreatitis: Prevalence, predictors, and its impact on quality of life

INTRODUCTION

Malnutrition in chronic pancreatitis (CP) has prognostic value and there is limited data on the prevalence, predictors of malnutrition in CP and its effect on Quality of life (QoL).

METHODS

A retrospective study was conducted in patients with CP to assess the prevalence of malnutrition as per the Global Leadership Initiative on Malnutrition (GLIM) criteria. Multivariable-adjusted regression was used to identify independent predictors of both malnutrition and global QoL.

RESULTS

A total of 297 patients were included and the most common etiology of CP was idiopathic (75%) and alcohol (25%). The prevalence of malnutrition was 46.4% as per GLIM criteria. On univariate analysis, the risk of malnutrition was significantly higher in alcoholic etiology (p = 0.001), current alcohol consumption (p = 0.001), smokers (p < 0.001), those having higher cumulative days of pain in last 6 months (p < 0.001) and lower daily calorie intake (p = 0.019). On multivariate analysis, malnutrition was independently associated with current alcohol consumption (Odds ratio: 3.22, p = 0.017), current smokers (OR: 2.23, p = 0.042) and those having higher cumulative days of abdominal pain (OR: 1.01, p < 0.001), while higher daily calorie intake (per 100 kcal) (OR:0.94, p = 0.023) has reduced risk of malnutrition. Malnutrition (p = 0.015) and higher cumulative days of abdominal pain (p < 0.001) were independently associated with lower global QoL in patients with CP.

CONCLUSION

Malnutrition is frequent in patients with CP; and current alcohol consumption, smoking and higher cumulative days of abdominal pain independently predicts risk of developing malnutrition. Patients with malnutrition and higher cumulative days of pain has poorer quality of life.

Sarcopenia in Chronic Pancreatitis - Prevalence, Diagnosis, Mechanisms and Potential Therapies

PURPOSE OF REVIEW

To investigate the prevalence, pathogenesis, diagnosis, clinical sequelae, and management of sarcopenia to improve mortality and quality of life in those with Chronic Pancreatitis.

RECENT FINDINGS

Sarcopenia is prevalent in chronic pancreatitis and can significantly affect clinical outcomes. Sarcopenia is prevalent in chronic pancreatitis. While effects on some clinical outcomes is has been shown, there is a significant gap in knowledge regarding effects on outcomes, pathophysiology, and options for management.

IgG4-related diseases of the digestive tract

IgG4-related conditions affecting the digestive tract are part of a multi-organ fibro-inflammatory disorder termed IgG4-related disease (IgG4-RD), with autoimmune pancreatitis and IgG4-related cholangitis being the most prominent manifestations. Gastrointestinal symptoms include jaundice, weight loss, abdominal pain, biliary strictures, and pancreatic and hepatic masses that mimic malignant diseases. IgG4-RD manifestations occur less frequently elsewhere in the digestive tract, namely in the oesophagus, retroperitoneum or intestine. Evidence-based European guidelines frame the current state-of-the-art in the diagnosis and management of IgG4-related digestive tract disease. Diagnosis is based on histology (if available), imaging, serology, other organ involvement and response to therapy (HISORt criteria). Few biomarkers beyond serum IgG4 concentrations are reliable. The first-line therapy (glucocorticoids) is swiftly effective but disease flares are common at low doses or after tapering. Second-line therapy might consist of other immunosuppressive drugs such as thiopurines or rituximab. Further trials, for example, of anti-CD19 drugs, are ongoing. Although an association between IgG4-RD and the development of malignancies has been postulated, the true nature of this relationship remains uncertain at this time.

A brief review of clinical guidelines for the diagnosis and treatment of exocrine pancreatic insufficiency

In recent years, several consensus and guidelines for the diagnosis and treatment of chronic pancreatitis have been published. In 2017, the Russian and Pan-European (HaPanEU) consensus was published, in 2018 — the international consensus on minimal change pancreatitis, in 2020 — the clinical guidelines of the American College of Gastroenterology, in 2021 — the British clinical guidelines. Many of their provisions overlap. This review article analyzed the main provisions of the latest recommendations, taking into account the possibility of their adaptation to Russian clinical practice.

Yield of testing for micronutrient deficiencies associated with pancreatic exocrine insufficiency in a clinical setting: An observational study

BACKGROUND

Pancreatic exocrine insufficiency (PEI) can be difficult to diagnose and causes maldigestion symptoms and malabsorption. There has been a number of studies that have identified PEI associated micronutrient deficiencies (PEI-MD), however there is variation in both the frequency and type of PEI-MD reported, with the majority of studies including patients with PEI due to chronic pancreatitis (CP) or CP without PEI. There is a paucity of information regarding the prevalence of PEI-MD in patients with PEI without CP and the yield of testing for PEI-MD in a clinical setting in patients with suspected benign pancreatic diseases.

AIM

To prospectively assess the yield and type of PEI–MD in patients with and without PEI secondary to benign pancreatic disease.

METHODS

Patients investigated for maldigestion symptoms with Faecal Elastase-1 (FEL-1) and suspected or proven benign pancreatic disease were prospectively identified. At the time of FEL-1 testing, serum samples were taken for micronutrients identified by previous studies as PEI-MD: prealbumin, retinol binding protein, copper, zinc, selenium, magnesium and later in the study lipid adjusted vitamin E. FEL-1 was recorded, with a result < 200 µg/g considered diagnostic of PEI. Patients underwent computed tomography (CT) imaging when there was a clinical suspicion of CP, a new diagnosis of PEI recurrent, pancreatic type pain (epigastric abdominal pain radiating to back with or without previous acute pancreatitis attacks) or weight loss.

RESULTS

After exclusions, 112 patients were recruited that underwent testing for FEL-1 and PEI-MD. PEI was identified in 41/112 (36.6%) patients and a pancreatic CT was performed in 82 patients. Overall a PEI-MD was identified in 21/112 (18.8%) patients. The yield of PEI-MD was 17/41 (41.5%) if PEI was present which was significantly higher than those without 4/71 (5.6%) (P = 0.0001). The yield of PEI–MD was significantly higher when PEI and CP were seen together 13/22 (59.1%) compared to CP without PEI and PEI without CP (P < 0.03). Individual micronutrient assessment showed a more frequent occurrence of prealbumin 8/41 (19.5%), selenium 6/41 (14.6%) and magnesium 5/41 (12.2%) deficiency when PEI was present (< 0.02). The accuracy of using the significant micronutrients identified in our cohort as a predictor of PEI showed a positive predictive value of 80%-85.7% [95% confidence interval (CI): 38%-100%] and a low sensitivity of 9.8%-19.5% [95% CI: 3.3%-34.9%].

CONCLUSION

Testing for PEI-MD in patients with suspected pancreatic disease has a high yield, specifically when PEI and CP are found together. PEI-MD testing should include selenium, magnesium and prealbumin.

Pancreatitis in Children

Pediatric pancreatitis describes a spectrum covering acute pancreatitis, acute recurrent pancreatitis, and chronic pancreatitis, each with varying clinical manifestations and risk factors requiring a tailored diagnostic approach. We emphasize management strategies based on age, risk factors, recurrence, and complications. A discussion of the role of therapeutic endoscopy is reviewed and highlights the growing role of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography in children with pancreatitis. Particular diagnostic challenges in autoimmune pancreatitis are reviewed with an emphasis on differentiating this entity from alternate pancreaticobiliary pathologies. Finally, we explore a multidisciplinary approach to acute recurrent and chronic pancreatitis.

Dietary intake in patients with chronic pancreatitis: A systematic review and meta-analysis

BACKGROUND

A progressive reduction in the secretion of pancreatic enzymes in patients with chronic pancreatitis (CP) results in malabsorption and ultimate malnutrition. However, the pathogenesis of malnutrition is multifactorial and other factors such as chronic inflammation, alcohol excess and poor dietary intake all contribute. Patients may restrict their dietary intake due to poor appetite or to avoid gastrointestinal symptoms and abdominal pain. Whilst up to half of patients with chronic pancreatitis are reportedly malnourished, the dietary intake of patients with CP is relatively understudied and has not been systematically reviewed to date.

AIM

To perform a systematic review and meta-analysis of the dietary intakes of patients with CP compared to healthy controls, and to compare the dietary intake of patients with alcohol-related CP and non-alcohol-related CP.

METHODS

A systematic literature search was performed using EMBASE, MEDLINE, and Cochrane review on studies published between 1946 and August 30^th, 2019. Adult subjects with a diagnosis of CP who had undergone dietary assessment were included in the systematic review (qualitative analysis). Studies on patients with other pancreatic diseases or who had undergone pancreatic surgery were not included. Studies comparing the dietary intake of patients with CP to that of healthy controls were included in the meta-analysis (quantitative analysis). Meta-analysis was performed using Review Manager 5.3. Newcastle Ottawa Scale (NOS) was used to assess quality of studies.

RESULTS

Of 6715 studies retrieved in the search, 23 were eligible for qualitative analysis while 12 were eligible for quantitative analysis. In the meta-analysis, the total energy (calorie) intake of patients with CP was similar to that of healthy controls [mean difference (MD): 171.3; 95% confidence interval (CI): -226.01, 568.5; P = 0.4], however patients with CP consumed significantly fewer non-alcohol calories than controls [MD: -694.1; 95%CI: -1256.1, (-132.1); P = 0.02]. CP patients consumed more protein, but carbohydrate and fat intakes did not differ significantly. Those with alcohol-related CP consumed more mean (standard deviation) calories than CP patients with a non-alcohol aetiology [2642 (1090) kcal and 1372 (394) kcal, respectively, P = 0.046], as well as more protein, fat, but not carbohydrate.

CONCLUSION

Although patients with CP had similar calorie intake to controls, studies that analysed the contribution of alcohol to energy intake showed that patients with CP consumed fewer non-alcohol calories than healthy controls. A high calorie intake, made up to a large degree by alcohol, may in part contribute to poor nutritional status in CP.

Osteosarcopenia in chronic pancreatitis

Aim. To determine clinical features and some mechanisms of osteosarcopenia development in patients with chronic pancreatitis (CP). Materials and methods. A casecontrol study was conducted on the basis of the Saratov State Clinical Hospital 5 in 20152018 of patients with CP. In a study of 161 patients with CP included, the control group 30 healthy individuals. Patients were divided into groups according to the etiology of CP: 79 with toxic-metabolic CP, 82 with biliary CP. To determine the risks of low-energy fractures, 154 patients were tested with the Fracture risk assessment tool (FRAX). Along with the standard examination, 30 patients with CP dual-energy X-ray absorptiometry was performed. To assess the state of skeletal muscles, body mass index was determined, hand-held dynamometry was performed, and a set of Short Physical Performance Battery (SPPB) tests was used. Along with the assessment of traditional risk factors for osteosarcopenia gender, age, state of reproductive function in women, body mass index, functional state of the pancreas (pancreas) the quantitative content of interleukins (IL)-2, 6, 8 in in colonic biopsies was analyzed by enzyme-linked immunosorbent assay (ELISA). Results. Bone disorders, according to densitometry, was detected in 70.0% of patients with CP, in 13.3% of the control group. Presarcopenia was detected in 62 (38.5%) patients with CP, sarcopenia in 34 (21.1%), in the control group presarcopenia and sarcopenia were not detected. Sarcopenia was statistically significantly more common in toxic-metabolic CP than in biliary CP (2=11.6; p0.001). Correlations of the lumbar spine T-score and IL-6 (r=-0.29; p=0.03), IL-8 (r=-0.29; p=0.04) were revealed. Correlations between sarcopenia and the concentration of cytokines in the in the colon mucosa in CP were determined (IL-2: r=0.44; p0.001; IL-6: r=0.48; p0.001; IL-8: r=0.42; p0.001). Conclusion. The development of osteopenia and sarcopenia syndromes in CP is interrelated and associated with both traditional risk factors and an increased concentration of cytokines in the in the colon mucosa.

Computed Tomographic Sarcopenia in Pancreatic Cancer: Further Utilization to Plan Patient Management

Purpose

The presence of a sarcopenia adversely affects the prognosis of patients with pancreatic cancer. There is an emerging role for using computed tomography (CT) to calculate skeletal muscle index (SMI) and the presence of sarcopenia. The aim of this study was to assess if detecting ‘computed tomographic sarcopenia’ is feasible and can contribute to the management of patients with locally advanced pancreatic cancer (LAPC).

Methods

Patients diagnosed with LAPC referred for endoscopic ultrasound-guided biopsy (EUS-B) by our regional cancer network were identified. Age, body mass index (BMI), and Eastern Cooperative Oncology Group performance status (ECOG-PS) were noted. CT images were analysed for SMI and the presence of sarcopenia. Decision outcomes on receiving chemotherapy or not were collected from the regional oncology database.

Results

In total, 51/204 (25%) patients with LAPC who underwent EUS-B were not given chemotherapy and received best supportive care (BSC) only. The prevalence of sarcopenia (p = 0.0003), age ≥ 75 years old (p = 0.03), and ECOG-PS 2–3 (p = 0.01) were significantly higher in the patients receiving BSC only. Logistic regression analysis demonstrated that SMI was the only independent associated factor identifying patients with LAPC who were treated with BSC only and not chemotherapy after adjusting for age and ECOG-PS.

Conclusion

Our study has shown that computed tomographic skeletal muscle analysis at the time of a diagnostic CT for patients with pancreatic cancer is feasible and can detect sarcopenia and malnourished patients who are much less likely to take up chemotherapy. These patients could be triaged to oncology assessment prior to EUS-B to avoid unnecessary investigations.

Does Provider Type Affect Bone Health Surveillance in Chronic Pancreatitis?

BACKGROUND

Bone density screening (DEXA) and vitamin D serum assay (Vit-D) are recommended in chronic pancreatitis, but adherence by providers is unknown.

AIMS

Assess DEXA/Vit-D testing according to provider type.

METHODS

A retrospective cohort study of chronic pancreatitis patients followed in a tertiary hospital (August 2017-2018) was conducted. Provider type was primary care (PCP), gastroenterologist, and pancreas specialist. Chi-square test and multivariable analysis were conducted to assess the relation between provider type and DEXA/Vit-D testing. Subset analyses were performed among patients with fecal elastase < 200 mcg/g.

RESULTS

A total of 478 charts were reviewed, and 256 (53.6%) met diagnosis of chronic pancreatitis; 184 (71.9%) definite, 45 (17.6%) probable, and 27 (10.6%) borderline chronic pancreatitis. DEXA was tested in 112/256 (43%) patients; 16/57(28%) patients followed by PCP, 11/38 (28.9%) by gastroenterologists, and 85/161(52.2%) by pancreas specialists (p = 0.001). Vit-D was tested in 210/256 (82.0%) patients; 42/57(73.7%) followed by PCP, 29/38 (76.3%) by gastroenterologists, and 139/161(86.3%) by pancreas specialists (p = 0.06). Multivariate analysis assessing DEXA/Vit-D testing showed pancreas specialists were more likely to test compared to PCP (DEXA: OR 3.70, CI 1.77-7.74, p = 0.001. Vit-D: OR 3.24, CI 1.43-7.38, p = 0.005), but gastroenterologists were not. In patients with low fecal elastase, pancreas specialists were more likely to test DEXA (pancreas specialists: 62.1%, PCP: 40.0%, Gastroenterologists: 11.1%, p = 0.01) and all patients received Vit-D testing.

CONCLUSIONS

Chronic pancreatitis patients often do not receive optimal preventive care. Pancreas specialists were more likely to perform DEXA and Vit-D testing compared to PCP and gastroenterologists. More physician education is needed.

Consensus for the management of pancreatic exocrine insufficiency: UK practical guidelines

INTRODUCTION

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.

METHODS AND ANALYSIS

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.

RESULTS

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.

A retrospective cohort study of nutritional status, nutritional interventions and hospital admissions in patients with chronic pancreatitis managed at a tertiary referral centre

PURPOSE

Chronic pancreatitis (CP) is a complex disease process causing abdominal pain, diarrhoea and weight loss. The long-term nutritional implications however are not well documented. The aim of this study was to evaluate nutritional status in patients with CP over an extended time period and assess frequency and duration of CP related hospitalisation.

METHODS

Retrospective analysis of patients with known CP for nutritional status (weight, BMI, and weight changes), nutritional interventions and hospital admissions were recorded. Weight was recorded at 3 points; baseline consultation, first review and most recent consultations. Number of dietitian contacts and documented evidence of nutritional advice/interventions were recorded and grouped. Nutritional status was compared in those who had dietetic input with those who did not.

RESULTS

46 consecutive subjects (34/46 male, mean age 56.15 years, 26/46 alcohol aetiology) were followed up for a mean of 5.24 years. 38/46 lost weight from baseline to review with mean percentage weight change: baseline to review = -7.36, p < 0.0001, baseline to recent = -6.70, p = 0.003, review to recent = 1.47, p = 0.581. 23/46 were reviewed by dietitian (mean 4.65 reviews). The number of dietitian reviews were positively associated with weight gain; baseline to recent (p = 0.010) and review to recent (p = 0.011). 23/46 received nutritional advice/interventions with 11 requiring enteral feeding. 29/46 experienced unplanned CP related hospital admissions (median 3) comprising 30 median total admission days.

CONCLUSION

Patients with CP lose a significant amount of weight in a short time period which plateaus. Dietitian review is associated with improved nutritional status in CP.

Small and Large Intestine (I): Malabsorption of Nutrients

Numerous disorders can alter the physiological mechanisms that guarantee proper digestion and absorption of nutrients (macro- and micronutrients), leading to a wide variety of symptoms and nutritional consequences. Malabsorption can be caused by many diseases of the small intestine, as well as by diseases of the pancreas, liver, biliary tract, and stomach. This article provides an overview of pathophysiologic mechanisms that lead to symptoms or complications of maldigestion (defined as the defective intraluminal hydrolysis of nutrients) or malabsorption (defined as defective mucosal absorption), as well as its clinical consequences, including both gastrointestinal symptoms and extraintestinal manifestations and/or laboratory abnormalities. The normal uptake of nutrients, vitamins, and minerals by the gastrointestinal tract (GI) requires several steps, each of which can be compromised in disease. This article will first describe the mechanisms that lead to poor assimilation of nutrients, and secondly discuss the symptoms and nutritional consequences of each specific disorder. The clinician must be aware that many malabsorptive disorders are manifested by subtle disorders, even without gastrointestinal symptoms (for example, anemia, osteoporosis, or infertility in celiac disease), so the index of suspicion must be high to recognize the underlying diseases in time.

Nutritional treatment is associated with longer survival in patients with pancreatic disease and concomitant risk of malnutrition

BACKGROUND

Pancreatic diseases involve complex nutritional challenges. Despite this, conflicting evidence exists regarding the clinical relevance of detecting the risk of malnutrition and implementing systematic nutrition support for these patients. Thus, our aims were to investigate whether screening for malnutrition risk and initiating nutrition support are predictive of mortality for hospitalized patients with pancreatic diseases.

DESIGN

From 2008 to 2018, 34 prevalence surveys of nutrition were conducted at Haukeland University Hospital (HUH), Norway. Risk of malnutrition was defined by a score of ≥3 in Nutritional Risk Screening 2002 (NRS 2002). Primary outcomes included overall, one-year, and one-month mortality, and were compared according to malnutrition risk and nutrition support for adult patients with ICD-10 codes of K85: acute pancreatitis, K86: other diseases of pancreas, and C25: malignant neoplasm of pancreas. Length of hospital stay (LOS) was included as a secondary outcome.

RESULTS

Of the 283 patients investigated, risk of malnutrition was present in 61.5%. Risk of malnutrition was associated with higher overall mortality (Hazard Ratio (HR) = 1.67, 95% confidence interval (CI): 1.2-2.4, P = 0.003) and one-year mortality (HR = 1.89, 95% CI: 1.2-2.9, P = 0.004) compared to patients not at risk. Not receiving nutrition support for at-risk patients was associated with higher overall mortality (HR = 1.60, 95% CI: 1.1-2.4, P = 0.019) and one-year mortality (HR = 1.64, 95% CI: 1.04-2.6, P = 0.034) compared to patients at risk who received nutrition support. Patients at risk of malnutrition had increased LOS (20.5 nights vs 15.2 nights, P = 0.044) compared to patients not at risk of malnutrition.

CONCLUSION

This study of hospitalized patients with pancreatic disease suggests that risk of malnutrition may be associated with higher mortality rates, whereas nutrition support may decrease mortality rates.

Nutritional management of chronic pancreatitis: A systematic review and meta-analysis of randomized controlled trials

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.

Body Composition is Associated With Islet Function After Pancreatectomy and Islet Autotransplantation for Pancreatitis

CONTEXT

Body composition in total pancreatectomy with islet autotransplantation (TPIAT) has never been studied.

OBJECTIVE

Determine whether presurgical body composition is associated with islet function and insulin sensitivity after TPIAT.

METHODS

In 88 adults undergoing TPIAT (median age 41.0 years, IQR 32.8-48.0), beta-cell function and insulin sensitivity were assessed using mixed meal tolerance test and frequent sample intravenous glucose tolerance test before surgery and 12 and 18 months afterward. Body composition was measured by dual x-ray absorptiometry. Analyses used linear and logistic regression.

RESULTS

Before surgery, 8 individuals (9.1%) were underweight, 40 (45.5%) normal weight, 20 (22.7%) overweight, and 20 (22.7%) obese. Overweight/obese patients had higher area under the curve C-peptide and lower insulin sensitivity index. Baseline body weight was positively associated with first-phase insulin secretion (AIRg) at 12 months (average 38.5 [SE 17.1] mU/L/min higher per extra kg; P = 0.03) and 18 months (38.3 [18.5]; P = 0.04), while baseline lean mass was inversely associated with AIRg at 12 months (-0.05 [0.02] per extra kg; P = 0.01) and 18 months (-0.05 [0.02]; P = 0.03). Percent gynoid fat was inversely associated with disposition index at 18 months (-206.0 [97.2] per extra percent; P = 0.04). Percent body fat and percent gynoid fat were associated with glucose effectiveness index at 18 months (1.9 × 10-3 [0.9 × 10-3] per extra percent; P = 0.04 and -1.96 × 10-3 [0.8 × 10-3]; P = 0.02, respectively). Insulin independence was not significantly associated with body weight or composition.

CONCLUSIONS

Half of these chronic pancreatitis patients were overweight/obese; underweight was uncommon. Preoperative body weight and composition were associated with islet function but not insulin independence after TPIAT.

Prevalence and predictive factors of undernutrition and low bone mineral density in children with chronic pancreatitis

BACKGROUND

Malnutrition and bone disease are common in adults with chronic pancreatitis (CP). We studied the nutritional status and bone mineral density (BMD) of children with CP and the factors predicting them.

METHODS

CP children were prospectively evaluated with a detailed questionnaire, anthropometry, 25-hydroxy vitamin D, fecal elastase and BMD [total body less head (TBLH), spine and hip] by dual energy x-ray absorptiometry. Body mass index (BMI) Z score of -1 to -1.9, -2 to -2.9 and <-3 was taken as mild, moderate and severe malnutrition respectively. Low BMD and osteoporosis were defined as per International Society for Clinical Densitometry.

RESULTS

83 children (46 boys, 14[4.3-21]years) with CP were enrolled. Majority had Cambridge IV (51,62.2%) or III (15,18.3%) changes. 34(41%) had undernutrition (mild-37.3%, moderate-2.4%, severe-1.2%). Overweight and obesity were present in 3.6% and 1.2% cases. BMI had a significant correlation with haemoglobin, serum albumin, percentage body fat and BMD. A majority had low fecal elastase (69 [84.1%], <100 μg/g) and vitamin D deficiency (70[84.3%],<20 ng/ml). 9 cases had a history of fractures. 14/75(18.6%) cases had low TBLH-BMD and this group had a lower BMI (-1.3[-1.9 to 0.34] vs 0.8 [-2.1 to 5.50; p = 0.03) than patients with normal BMD. There was no difference in age, disease duration, vitamin D, fecal elastase and Cambridge grade between normal and low BMD.

CONCLUSIONS

41% CP children have undernutrition with a majority having mild undernutrition. Nearly 20% have low BMD, with osteoporosis in none. Subjects with low BMI have lower BMD and percentage body fat.

Risk of Developing Pancreatic Cancer in Patients with Chronic Pancreatitis

Background: Patients with chronic pancreatitis (CP) have an increased risk of developing pancreatic ductal adenocarcinoma (PDAC). We present data on PDAC in one of the most extensive European single-centre cohort studies of patients with CP. Methods: Retrospective analysis of prospectively collected data of patients with CP was performed. Aetiology of CP was determined according to the M-ANNHEIM classification system and only patients with definite CP > 18 years at data analysis were included. The final dataset included 581 patients with definite CP diagnosed between 2003 and 2018. Results: At CP diagnosis, there were 371 (63.9%) males and 210 (36.1%) females (median age 57 years, range 2–86). During 3423 person-years of observation, six pancreatic cancers were diagnosed (0.2% year). The mean time between diagnosis of CP and the occurrence of PDAC was 5.0 years (range 2.7–8.6). None of the cancer patients had a family history of PDAC. Diabetes mellitus (DM) was present in five of six (83.3%) patients with PDAC: in three patients before and in two after CP diagnosis. Clinical/laboratory signs of pancreatic exocrine insufficiency (PEI) were present in five of six (83.3%) patients with PDAC: in two at diagnosis of CP and in three after diagnosis. The mean survival time was 4 months after the diagnosis of PDAC (range 0.5–13). PDAC occurred significantly more often (p < 0.001) in two groups of patients without previous acute pancreatitis (AP): 2 of 20 patients (10%) with low body mass index (BMI) and PEI and in 3 of 10 (30%) patients with high BMI and DM at diagnosis of CP. Conclusions: Patients with CP have a high risk of developing PDAC, although risk is low in absolute terms. Our data suggest the possibility of defining subgroups of patients with a particularly elevated risk of PDAC. Such a possibility would open a path to personalised decision making on initiation of PDAC surveillance of patients with no previous episode of AP, (i) with low BMI and PEI, or (ii) elevated BMI and DM.

Effect of Fat-Soluble Vitamins A, D, E and K on Vitamin Status and Metabolic Profile in Patients with Fat Malabsorption with and without Urolithiasis

Patients with intestinal fat malabsorption and urolithiasis are particularly at risk of acquiring fat-soluble vitamin deficiencies. The aim of the study was to evaluate the vitamin status and metabolic profile before and after the supplementation of fat-soluble vitamins A, D, E and K (ADEK) in 51 patients with fat malabsorption due to different intestinal diseases both with and without urolithiasis. Anthropometric, clinical, blood and 24-h urinary parameters and dietary intake were assessed at baseline and after ADEK supplementation for two weeks. At baseline, serum aspartate aminotransferase (AST) activity was higher in stone formers (SF; n = 10) than in non-stone formers (NSF; n = 41) but decreased significantly in SF patients after supplementation. Plasma vitamin D and E concentrations increased significantly and to a similar extent in both groups during intervention. While plasma vitamin D concentrations did not differ between the groups, vitamin E concentrations were significantly lower in the SF group than the NSF group before and after ADEK supplementation. Although vitamin D concentration increased significantly in both groups, urinary calcium excretion was not affected by ADEK supplementation. The decline in plasma AST activity in patients with urolithiasis might be attributed to the supplementation of ADEK. Patients with fat malabsorption may benefit from the supplementation of fat-soluble vitamins ADEK.

Micronutrient deficits in patients with chronic pancreatitis: prevalence, risk factors and pitfalls

OBJECTIVE

We investigated the prevalence of micronutrient deficiencies and associated patient and disease-related risk factors in patients with chronic pancreatitis (CP).

METHODS

We enrolled 115 consecutive CP outpatients. Micro-nutritional assessments included plasma levels of fat-soluble vitamins (A, D and E) and trace elements (magnesium and zinc). Bioelectrical impedance and muscle function tests were used to characterize the macro-nutritional status (sarcopenia and phase angle). Prevalence of micro-nutritional deficiencies was estimated and associated with a number of patient and disease characteristics including presence of exocrine pancreatic insufficiency (EPI) and diabetes mellitus. In an additional analysis, we explored the association between micronutrient levels and macro-nutritional status.

RESULTS

The mean age of patients was 57.9 ± 13.0 years, 71% were men and 50% had an alcoholic aetiology. Vitamin D deficiency (22%) was the most common micronutrient deficit followed by zinc deficiency (20%) and magnesium deficiency (17%). Vitamin A deficiency (10%) and vitamin E deficiency (7%) were only seen in patients with EPI (P ≤ 0.03), while the presence of trace element deficits was associated with plasma albumin levels (P ≤ 0.006). Plasma zinc levels were decreased in sarcopenic patients (P < 0.001) and positively correlated to phase angle (coefficient 0.28; P < 0.001).

CONCLUSION

Various micronutrient deficits were observed in CP outpatients, and associated risk factors were diverse and distinct for the individual nutrients. Taken together, our findings highlight the complexity of micronutrient assessment in patients with CP and emphasise the importance of simultaneous evaluation of plasma protein levels, inflammatory activity and macro-nutritional status.
