OBJECTIVE: The aim of our study was to elucidate the clinical characteristics of alcoholic-hyperlipidemic etiologically complex acute pancreatitis. PATIENTS AND METHODS: We reviewed complete data from 233 patients with acute pancreatitis treated in our hospital during the period January 2017-January 2022. They were divided into three groups according to etiology: alcoholic acute pancreatitis (AAP), hyperlipidemic acute pancreatitis (HLAP), and alcoholic-hyperlipidemic acute pancreatitis (AHAP). General clinical data, co-morbidities, laboratory results, imaging data, and disease severity were analyzed and compared between groups. RESULTS: The proportion of male individuals in the AHAP group was significantly higher than that in the HLAP group (p0.05). CONCLUSIONS: The clinical characteristics of patients in the AHAP, AAP and HLAP groups were different, and the patients in the AHAP group were more likely to have a moderate to severe disease course, with longer hospital stay. As a new AP classification concept, AHAP would offer high significance for diagnosis, treatment, and prognosis.

OBJECTIVES: Five percent of alcoholics develop an acute pancreatitis (AP). The mechanism leading to pancreatic injury is not yet understood. Microcirculatory disorders seem to play a pivotal role. The objective of this study was to compare alcoholic pancreatic injury in response to intravenous and intragastric routes of alcohol administration. METHODS: Alcohol was applied in rats intravenously (IV) or gastric via a surgical implanted feeding tube (IG). Serum alcohol concentration was maintained between 1.5‰ and 2.5‰. Four subgroups (n = 6/group) were examined in the IV/IG arm and compared with healthy controls. Pancreatic microcirculation, enzyme levels, and morphological damage were assessed after 3, 6, 12, and 24 hours. RESULTS: Microcirculatory analysis showed significantly disturbed pancreatic perfusion and increased adherent leukocytes in IV and IG animals. In IV and IG groups, serum amylase was increased without morphological signs of AP compared with healthy controls. CONCLUSIONS: Alcohol application does not induce AP in rodents, but impairs pancreatic microcirculation irrespectively of the application route. Intravenous application is commonly used and shows no disadvantages compared with the physiological intragastric application form. Therefore, the intravenous route offers a valid model, which mimics the physiological process for further studies of the influence of acute alcohol intoxication on the pancreas.

Alcoholic chronic pancreatitis (CP) is not usually diagnosed until the end stage of the disease, and hence enormous medical and social resources are consumed in the treatment of established alcoholic CP. With the aim of early diagnosis and prevention of alcoholic CP, we here propose “alcoholic pancreatopathy” as a new category of pancreatic disorder induced by alcohol intake. In addition to a history of excessive alcohol intake (>80 g/day), the presence of at least one of the following conditions establishes the diagnosis of alcoholic pancreatopathy:

Acute pancreatitis (AP) is a progressive systemic inflammatory response with high morbidity and high mortality, which is mainly caused by alcohol, bulimia, gallstones and hyperlipidemia. The early diagnosis of different types of AP and further explore potential pathophysiological mechanism of each type of AP is beneficial for optimized treatment strategies and better patient's care. In this study, a metabolomics approach based on gas chromatography-mass spectrometry (GC-MS), and random forests algorithm was established to distinguish biliary acute pancreatitis (BAP), Hyperlipidemia acute pancreatitis (HLAP), and alcoholic acute pancreatitis (AAP), from healthy controls. The classification accuracies for BAP, HLAP, and AAP patients compared with healthy control, were 0.886, 0.906 and 0.857, respectively, by using 5-fold cross-validation method. And some special metabolites for each type of AP were discovered, such as L-Lactic acid, (R)-3-Hydroxybutyric acid, Phosphoric acid, Glycine, Erythronic acid, L-Phenylalanine, D-Galactose, L-Tyrosine, Arachidonic acid, Glycerol 1-hexadecanoate. Furthermore, associations between these metabolites with the metabolism of amino acids, fatty acids were identified. Our studies have illuminated the biomarkers and physiological mechanism of disease in a clinical setting, which suggested that metabolomics is a valuable tool for identifying the molecular mechanisms that are involved in the etiology of BAP, AAP, HLAP and thus novel therapeutic targets.

Objectives The aim of this investigation was to evaluate the pancreatographic findings and dynamics of pancreatic duct diameter, as determined by secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP), in patients with acute alcoholic pancreatitis or chronic alcoholic pancreatitis and in a control group. Methods S-MRCP was performed in patients with acute alcoholic pancreatitis who did not manifest the functional and radiological (ultrasonography and computed tomography) criteria of chronic pancreatitis (n = 21), in patients with chronic alcoholic pancreatitis (n = 28) and in a control group (n = 16). The diameter of the main pancreatic duct (MPD) was monitored before secretin administration and at 3 and 10 min after secretin administration. Morphological features were also assessed before and after the administration of secretin. Results All ductal diameters were significantly larger in chronic alcoholic pancreatitis (P < 0.0001). There were no differences in MPD caliber between patients with acute alcoholic pancreatitis and the control group. The percentage of variation between basal MPD diameter and at 3 min post-secretin administration was lower in patients with chronic (35.5%) pancreatitis than in those with acute alcoholic pancreatitis (52.3%) and the control group (52.5%). There were no significant differences between patients with acute alcoholic pancreatitis and the control group in terms of the frequency of visualization of side branches, ductal narrowing, intraluminal filling defects, and ductal irregularity. One patient with acute alcoholic pancreatitis presented ductal criteria of chronic pancreatitis following the administration of secretin. Conclusions The dynamics of MPD visualized on S-MRCP in patients with acute alcoholic pancreatitis is similar to that observed in the control group and different from that observed in patients with chronic alcoholic pancreatitis. There were no significant differences between patients with acute alcoholic pancreatitis and the control group in terms of morphological pancreatographic features.

This retrospective study was conducted to assess the serum lipase / amylase ratio in acute pancreatitis for South Indian population attending the clinics of Gastroenterology and Emergency medicine in the last five years. One thousand one hundred and thirty two patients (768 males and 364 females) with acute pancreatitis (AP) were selected for the study. The diagnosis ofAP was based on clinical evaluation, Computed Tomography (CT) findings and biochemical parameters such as serum lipase and amylase. Based on the etiology, the groups were divided into alcoholic, biliary and miscellaneous AP. Based on CT findings, groups were divided into mild, moderate and severe AP. Serum lipase, amylase and lipase / amylase ratio were calculated and statistically analyzed. Serum lipase levels in alcoholic group (3226.3 +- 1384.7) were significantly lower in comparison to biliary (6064.5 +- 1640.8) group though the levels were not significantly different from miscellaneous group (2132.3 + 1210). Serum amylase values were significantly lower in alcoholic group (923.4 +- 557.5) in comparison to biliary (1736.2 +- 390.7) and there was significant difference between alcoholic and miscellaneous group (535.8 +- 477.6). The serum lipase / amylase ratio > 4 occurred in alcoholic group than with biliary and miscellaneous group. The sensitivity and specificity to predict alcoholic AP with lipase / amylase ratio at>4.0 was 84 % and59 % respectively. In conclusion the serum lipase to amylase ratio greater than 3.0 could be used to differentiate but keeping the cut off at 4.0 would be of higher sensitivity without much change in specificity. The serum lipase to amylase ratio with a cut off of 3.0 or greater is not useful to differentiate the severe AP from milder AP. Hence, serum amylase and lipase are important for evaluation of pancreatitis though it is not a gold standard for the diagnosis or assessment of severity of acute pancreatitis.
