Goodger R, Singaram K, Petrov MS. Prevalence of Chronic Metabolic Comorbidities in Acute Pancreatitis and Its Impact on Early Gastrointestinal Symptoms during Hospitalization: A Prospective Cohort Study. Biomed Hub 2021; 6:111-117. [PMID: 34950672 PMCID: PMC8647128 DOI: 10.1159/000519826] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Accepted: 09/22/2021] [Indexed: 12/25/2022] Open
Abstract
Background The prevalence of chronic comorbidities is increasing worldwide, and this has been paralleled by a growing interest in how these comorbidities affect patients with acute pancreatitis. The aim was to investigate the associations between pre-existing diabetes mellitus, obesity, metabolic syndrome, and gastrointestinal symptoms during the early course of acute pancreatitis. Methods This was a prospective cohort study of patients with a primary diagnosis of acute pancreatitis. Study groups were formed based on the presence of metabolic comorbidities (pre-existing diabetes mellitus, obesity, and metabolic syndrome). Patient-reported outcomes (nausea, bloating, and abdominal pain) were collected prospectively every 24 h (including weekends and public holidays) over the first 72 h of hospitalization. Results A total of 183 consecutive patients were enrolled. Of them, 111 (61%) had at least one major metabolic comorbidity. Patients with pre-existing diabetes mellitus and those with metabolic syndrome had worse nausea at 49-72 h of hospitalization (p = 0.017 and p = 0.012, respectively), but not at other time points. Bloating and abdominal pain did not differ between the study groupings throughout the study period. The studied patient-reported outcomes did not differ significantly between acute pancreatitis patients with and without obesity at any point in time. Conclusion More than 3 out of 5 patients hospitalized for acute pancreatitis have at least one major chronic metabolic comorbidity. The presence of metabolic comorbidities does not considerably and consistently affect early gastrointestinal symptoms in patients with acute pancreatitis.

Abstract
Background General obesity has been linked to dysregulation of the endocannabinoid system in humans. However, there is a lack of studies on the relationship between cannabis use and specific abdominal fat phenotypes. The aim was to investigate the associations between cannabis use and magnetic resonance imaging-derived fat phenotypes, as well as indices of insulin sensitivity and insulin secretion. Methods In this cross-sectional study, magnetic resonance imaging was used to quantify subcutaneous fat volume (SFV), visceral fat volume (VFV), intra-hepatic fat deposition (IHFD), intra-pancreatic fat deposition (IPFD) and skeletal muscle fat deposition (SMFD) by two independent observers. Insulin sensitivity was determined based on HOMA-IS, Raynaud index and Matsuda index, whereas insulin secretion was determined based on HOMA-β, insulinogenic index 30’ and insulinogenic index 60’. A validated questionnaire was used to ascertain participants’ cannabis use. Linear regression models were constructed, adjusting for demographics, glycated hemoglobin, physical activity, tobacco smoking and alcohol consumption. Results A total of 120 individuals were included. Cannabis use explained 9.2% of variance in IHFD, 4.4% in SMFD, 3.4% in VFV, 0.4% in SFV and 0.2% in IPFD. Regular cannabis users had significantly greater IHFD compared with never users, in both the unadjusted (P = 0.002) and all adjusted (P = 0.002; P = 0.008) analyses. The other fat phenotypes did not differ significantly between either regular or non-regular users compared with never users. Regular cannabis users had significantly greater insulin secretion (as defined by the insulinogenic index 60’) compared with never users, in both the unadjusted (P = 0.049) and all adjusted (P = 0.003; P = 0.004) analyses. Cannabis use explained 20.3% of variance in the insulinogenic index 60’, but was not significantly associated with the other indices of insulin secretion. There were no significant differences in indices of insulin sensitivity in either regular or non-regular cannabis users compared with never users. Conclusion Regular cannabis use may be a risk factor for non-alcoholic fatty liver disease (but not IPFD) and may alter the neuromodulation of insulin secretion. Further investigations are now warranted to elucidate the mechanisms underlying these associations.

Abstract
BACKGROUND AND AIM Approximately 40% of patients develop abnormal glucose metabolism after a single episode of acute pancreatitis. This study aimed to develop and validate a prediabetes self-assessment screening score for patients after acute pancreatitis. METHODS Data from non-overlapping training (n=82) and validation (n=80) cohorts were analysed. Univariate logistic and linear regression identified variables associated with prediabetes after acute pancreatitis. Multivariate logistic regression developed the score, ranging from 0 to 215. The area under the receiver-operating characteristic curve (AUROC), Hosmer-Lemeshow χ2 statistic, and calibration plots were used to assess model discrimination and calibration. The developed score was validated using data from the validation cohort. RESULTS The score had an AUROC of 0.88 (95% CI, 0.80-0.97) and Hosmer-Lemeshow χ2 statistic of 5.75 (p=0.676). Patients with a score of ≥75 had a 94.1% probability of having prediabetes, and were 29 times more likely to have prediabetes than those with a score of <75. The AUROC in the validation cohort was 0.81 (95% CI, 0.70-0.92) and the Hosmer-Lemeshow χ2 statistic was 5.50 (p=0.599). Model calibration of the score showed good calibration in both cohorts. CONCLUSION The developed and validated score, called PERSEUS, is the first instrument to identify individuals who are at high risk of developing abnormal glucose metabolism following an episode of acute pancreatitis.

Early management of acute pancreatitis: A review of the best evidence. Dig Liver Dis 2017; 49:585-594. [PMID: 28262458 DOI: 10.1016/j.dld.2017.01.168] [Citation(s) in RCA: 54] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Revised: 01/27/2017] [Accepted: 01/27/2017] [Indexed: 12/11/2022]
Abstract
In the 20th century early management of acute pancreatitis often included surgical intervention, despite overwhelming mortality. The emergence of high-quality evidence (randomized controlled trials and meta-analyses) over the past two decades has notably shifted the treatment paradigm towards predominantly non-surgical management early in the course of acute pancreatitis. The present evidence-based review focuses on contemporary aspects of early management (which include analgesia, fluid resuscitation, antibiotics, nutrition, and endoscopic retrograde cholangiopancreatography) with a view to providing clear and succinct guidelines on early management of patients with acute pancreatitis in 2017 and beyond.

Abstract
OBJECTIVES To study the effects of person-centred care provided to patients with acute coronary syndrome, using four different health-related outcome measures. Also, to examine the performance of these outcomes when measuring person-centred care. DATA AND METHOD The data used in this study consists of primary data from a multicentre randomized parallel group, controlled intervention study for patients with acute coronary syndrome at Sahlgrenska University Hospital in Gothenburg, Sweden. The intervention and control group consisted of 94 and 105 patients, respectively. The effect of the intervention on health-related outcomes was estimated, controlling for socio-economic and disease-related variables. RESULTS Patients in the intervention group reported significantly higher general self-efficacy than those in the control group six months after intervention start-up. Moreover, the intervention group returned to work in a greater extent than controls; their physical activity level had increased more and they had a higher EQ-5D score, meaning higher health-related quality of life. These latter effects are not significant but are all pointing towards the beneficial effects of person-centred care. All the effects were estimated while controlling for important socio-economic and disease-related variables. CONCLUSION The effectiveness of person-centred care varies between different outcomes considered. A statistically significant beneficial effect was found for one of the four outcome measures (self-efficacy). The other measures all captured beneficial, but not significant, effects.

Abstract
Tolerance of oral refeeding is an essential goal of nutritional management of acute pancreatitis. However, oral feeding intolerance remains one of the most common complications in patients with this disease. It often results in longer periods of hospitalization, increased treatment costs, increased risk of readmission, and reduced quality of life. The traditional practice involves keeping patients nil by mouth followed by gradual stepwise reintroduction of food. However, it does not have a solid evidence base and, hence, there is increasing interest in determining alternative strategies that may be beneficial in reducing the occurrence of oral feeding intolerance. This review focuses on the randomized controlled trials that investigated the key questions informing the nutritional management of acute pancreatitis: when to feed, what to feed and who is in charge of the decision-making.

Abstract
BACKGROUND Evidence from animal studies suggests that gastrointestinal motility is impaired in acute pancreatitis. Enteral nutrition, and more specifically nasogastric tube feeding, has emerged as a key treatment modality in patients with acute pancreatitis, but its effect on motility has not been investigated in this setting. The aim was to validate the Gastroparesis Cardinal Symptom Index (GCSI) in patients with acute pancreatitis and determine the effect of nasogastric tube feeding on GCSI. METHODS The study design was a randomized controlled trial. Patients were allocated to nasogastric tube feeding or nil per os within 24 hours of hospital admission. GCSI data from before randomization to 72 hours after randomization were analyzed. The test-retest reliability analysis was used to calculate Cronbach's α. RESULTS Seventeen patients were randomized to nasogastric tube feeding and 18 to nil per os. Overall, the total GCSI score significantly decreased over the study (F = 8.537; P = .001) but was not significantly different between the 2 study groups during hospitalization (F = 1.159; P = .322). However, patients on nasogastric tube feeding did show improved appetite compared with nil per os (F = 3.526; P = .036). The GCSI was found to be a reliable tool in the setting of acute pancreatitis (Cronbach's α = 0.852). CONCLUSIONS Nasogastric tube feeding does not appear to affect dysmotility symptoms in acute pancreatitis as measured by the GCSI, although appetite improved. Use of the simple, noninvasive, and inexpensive GCSI tool to evaluate motility is recommended in future clinical trials in pancreatology.
