Abstract
Enzymatically isolated pancreatic islets are the most commonly used ex vivo testbeds for diabetes research. Recently, precision-cut living slices of human pancreas are emerging as an exciting alternative because they maintain the complex architecture of the endocrine and exocrine tissues, and do not suffer from the mechanical and chemical stress of enzymatic isolation. We report a fluidic pancreatic SliceChip platform with dynamic environmental controls that generates a warm, oxygenated, and bubble-free fluidic pathway across singular immobilized slices with continuous deliver of fresh media and the ability to perform repeat serial perfusion assessments. A degasser ensures the system remains bubble-free while systemic pressurization with compressed oxygen ensures slice medium remains adequately oxygenated. Computational modeling of perfusion and oxygen dynamics within SliceChip guide the system's physiomimetic culture conditions. Maintenance of the physiological glucose dependent insulin secretion profile across repeat perfusion assessments of individual pancreatic slices kept under physiological oxygen levels demonstrated the culture capacity of our platform. Fluorescent images acquired every 4 hours of transgenic murine pancreatic slices were reliably stable and recoverable over a 5 day period due to the inclusion of a 3D-printed bioinert metallic anchor that maintained slice position within the SliceChip. Our slice on a chip platform has the potential to expand the useability of human pancreatic slices for diabetes pathogenesis and the development of new therapeutic approaches, while also enabling organotypic culture and assessment of other tissue slices such as brain and patient tumors.

Abstract
SCOPE Consuming goat milk is known to benefit high-fat diet-fed and streptozocin (STZ)-induced diabetic rats, but the underlying mechanisms are unknown. This study is conducted to investigate the metabolic effects of a goat milk diet (a form of goat milk powder) on glucose homeostasis and pancreatic conditions in a mouse model of Type 2 diabetes mellitus (T2DM) induced by STZ. METHODS AND RESULTS T2DM mice are fed with a goat-milk-based diet containing 10.3% w/w goat milk powder for 10 weeks for investigating the in vivo effects; a β-cell line MIN6 cells are used to test the in vitro effects of digested goat milk (DGM). Goat milk diet improves the deleterious effects of STZ on fasting glucose levels and glucose tolerance, accelerates pancreatic structure recovery, and alters blood metabolites in mice. Based on the significant differences observed in metabolites, the key pathways, metabolite regulatory enzymes, metabolite molecular modules, and biochemical reactions are identified as critical integrated pathways. DGM promotes the cell activity, glucose transportation, and AKT activation in cultured STZ-treated MIN6 cells in vitro. CONCLUSIONS Goat milk diet improves glucose homeostasis and pancreatic conditions of T2DM mice, in association with improved blood metabolite profiles and activation of pancreatic AKT pathway.

Int J Endocrinol 2022; 2022:7764963. [PMID: 36213198 PMCID: PMC9536940 DOI: 10.1155/2022/7764963] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 05/19/2022] [Accepted: 06/30/2022] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Exocrine pancreatic insufficiency (EPI) is common in patients with type 2 diabetes. However, the prevalence of EPI varies significantly in different studies. Untreated EPI in these patients can adversely affect their nutrition and metabolism. The aim of this study is to estimate the pooled prevalence of EPI in patients with type 2 diabetes and to explore the potential risk factors. METHODS A systematic search was performed in PubMed, Web of Science, and Embase, which included studies meeting inclusion criteria from 1960 to 1 April 2022. Relevant articles were searched using the combination of Medical Subject Heading (MeSH) terms of "Type 2 diabetes" and "pancreatic exocrine insufficiency." The Stata 16.0 software was used for data analyses. The random-effects model was used to estimate the pooled prevalence rates and 95% CI using "metaprop program." RESULTS The pooled prevalence of EPI was 22% (95% CI: 15%-31%) in patients with type 2 diabetes and 8% (95% CI: 4%-14%) of them developed severe pancreatic insufficiency. In the subgroup analyses, the prevalence of EPI in type 2 diabetes was correlated with geographic location. The prevalence in Asian countries (35%, 95% CI: 22%-49%) is higher than in Europe (18%, 95% CI: 10%-29%) and Australia (9%, 95% CI: 4%-16%). Furthermore, patients with higher insulin requirements, who are more likely to be insulin-deficient, have a higher prevalence of EPI. The pooled prevalence was 27% (95% CI: 17%-37%) in type 2 diabetes with higher insulin requirement (1 group) and 15% (95% CI: 1%-40%) in patients with lower insulin requirement (2 group). In addition, the morbidity of severe EPI in the higher insulin requirement group (12%, 95% CI: 7%-19%) was sextuple as much as the lower insulin requirement group (2%, 95% CI: 0%-13%). EPI was more common in subjects younger than 60 compared with elderlies (25% vs. 19%). CONCLUSION The prevalence of EPI in type 2 diabetes may be overestimated. Furthermore, the higher prevalence may be closely related to β-cell function. Endocrine disease therapy would potentially represent a novel therapeutic approach for patients with type 2 diabetes and EPI.

Two sides of the pancreas: Exocrine insufficiency is correlated with endocrine dysfunction in type 2 diabetes. Clin Chim Acta 2021; 523:81-86. [PMID: 34529982 DOI: 10.1016/j.cca.2021.09.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 09/07/2021] [Accepted: 09/09/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Recently, numerous studies validated frequent pancreatic exocrine dysfunction in patients with diabetes. However, the prevalence of pancreatic exocrine insufficiency (PEI) in diabetes mellitus (DM) varies widely among studies. This study aims to determine the prevalence of PEI in Chinese people with type 2 DM (T2DM) by measuring the fecal elastase-1 (FE-1) levels and further identify potential factors that influence pancreatic exocrine function in patients with T2DM. METHODS A total of 85 patients with T2DM without known exocrine pancreatic disorders or digestive system diseases were recruited. Fecal samples were submitted to measure FE-1 levels, and blood samples were collected to investigate pancreatic endocrine function and metabolic biomarkers in all participants. The multiple logistic regression analysis was established to evaluate the influencing factors of PEI in patients with T2DM. The potential predictors of PEI were examined using receiver operating characteristic (ROC) curves. RESULTS The prevalence of PEI measured by low FE-1 in T2DM was 18.8%. The Spearman correlation demonstrated that the FE-1 level was inversely correlated with DM duration (r = - 0.360, P = 0.001) and glycated hemoglobin (HbA1c) level (r = - 0.228, P = 0.036). A highly significant positive association was observed between FE-1 and fasting C-peptide (FCP) levels (r = 0.451, P < 0.001). Furthermore, the multiple logistic regression analysis showed that FCP was an independent influencing factor of PEI (OR = 0.204, P = 0.024, 95% CI: 0.051-0.813). The ROC analysis indicated that the FCP level had a predictive value for low FE-1 (AUC = 0.793, P < 0.001) with an optimal cutoff value of 1.20 ng/ml. CONCLUSION Chinese patients with T2DM show high PEI prevalence. FCP may be a potential predictor of pathological exocrine function in T2DM. The exocrine and endocrine functions of patients with T2DM in clinical practice should be evaluated. Further studies are needed to clarify the internal association between exocrine and endocrine pancreases.

Abstract
BACKGROUND AND AIMS We aimed to estimate the prevalence of exocrine pancreatic insufficiency (EPI) related fat malabsorption & to correlate it with measures of autonomic neuropathy in patients with T2DM from India. METHODS Patients with T2DM (cases; n = 118) and normo-glycaemic individuals (controls; n = 82) underwent anthropometry and biochemical evaluation at baseline. The 72-hours fecal fat excretion was estimated by the Van de Kamer's titration method. Autonomic neuropathy was evaluated using an automated analyzer. RESULTS The prevalence of EPI related fat malabsorption in cases was 45% (n = 53; 72 hours mean fecal fat level = 22.7 ± 5.6 g/day). Dysfunctions in the parasympathetic nervous system (PNS; 86.7%; p < 0.05), sympathetic nervous system (SNS; 92.4%; p < 0.05), and both; PNS + SNS (83.1%; p < 0.05) were significant. Amongst measures of PNS dysfunction, there was a significantly higher percentage of abnormal expiration: inspiration ratio (45.3%) and the 30:15 ratio (84.9%) (p < 0.05) in patients with T2DM and EPI related fat malabsorption. CONCLUSION In this cross-sectional cohort of Asian Indian patients with T2DM (n = 118), EPI related fat malabsorption correlates significantly with autonomic dysfunction in patients with T2DM. However, these preliminary data need to confirmed in trials with more robust design.

Abstract
Obesity is a growing health burden worldwide, increasing the risk for several diseases featuring the metabolic syndrome - type 2 diabetes mellitus, dyslipidemia, non-alcoholic fatty liver disease and cardiovascular diseases. With the increasing epidemic of obesity, a new pathologic condition has emerged as a component of the metabolic syndrome - that of non-alcoholic fatty pancreas disease (NAFPD). Similar to non-alcoholic fatty liver disease (NAFLD), NAFPD comprises a wide spectrum of disease - from deposition of fat in the pancreas - fatty pancreas, to pancreatic inflammation and possibly pancreatic fibrosis. In contrast with NAFLD, diagnostic evaluation of NAFPD is less standardized, consisting mostly in imaging methods. Also the natural evolution of NAFPD and its association with pancreatic cancer is much less studied. Not least, the clinical consequences of NAFPD remain largely presumptions and knowledge about its metabolic impact is limited. This review will cover epidemiology, pathogenesis, diagnostic evaluation tools and treatment options for NAFPD, with focus on practices for clinicians.

Abstract
The exocrine structure is significantly affected by diabetes because of endocrine structure-function disorder within the pancreas. Exocrine pancreatic dysfunction (EPD) is the general name of the malabsorption process resulting from inadequate production, release, decreased activation, and/or insufficient degradation of enzymes required for digestion from pancreatic acinar cells. It is important to diagnose patients early and correctly, since there may be both macro- and micro-nutrient deficiency in EPD. In this paper, EPD, the diabetes-EPD relationship, and the predictive, effective factors affecting the emergence of EPD are briefly explained and summarized with contemporary literature and our experienced based on clinical, lab, and radiological findings.
