Clinical features of elderly patients with acute pancreatitis aged ≥80 years / 临床肝胆病杂志

ObjectiveTo investigate the clinical features of elderly patients with acute pancreatitis (AP) aged ≥80 years. MethodsA retrospective analysis was performed for 3642 patients with pancreatitis who were admitted to Department of Gastroenterology in The Affiliated Hospital of Southwest Medical University from January 2013 to December 2019, and according to age, they were divided into young group (aged ＜65 years) with 2955 patients, middle-aged group (aged 65-79 years) with 558 patients, and elderly group (aged ≥80 years) with 129 patients. Related clinical data were collected and analyzed, including sex, age, etiology, predisposing factors, past medical history, disease severity, complication, and clinical outcome. The independent samples one-way ANOVA-test was used for comparison of normally distributed continuous data between groups and the least significant difference t-test was used for comparison within each group; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups; the Kruskal-Wallis H test was used for comparison of ordinal categorical variables. ResultsIn the young group, there were 1721 male patients and 1234 female patients; in the middle-aged group, there were 214 male patients and 334 female patients; in the elderly group, there were 48 male patients and 81 female patients; the middle-aged group and the elderly group had a significantly higher proportion of female patients than the young group (62.8% vs 61.6% vs 41.8%, P＜0.05). High-fat diet was the main predisposing factor for all three groups, and compared with the young group, the elderly group had a significantly lower proportion of patients with AP induced by alcohol or high-fat diet+alcohol (P＜0.05). The elderly group had a significantly higher proportion of patients with the etiology of biliary diseases than the middle-aged group and the young group (798% vs 69.2% vs 41.4%, χ2=204.127, P＜0.05), as well as a significantly lower proportion of patients with the etiology of hyperlipidemia, alcohol, or biliary diseases+hyperlipidemia (all P＜0.05). Among the 129 patients in the elderly group, 83 (64.3%) had mild AP, 23 (17.8%) had moderate-severe AP, and 23 (17.8%) had severe AP; there was a significant difference in the constituent ratio of disease severity between the elderly group and the middle-aged/young groups (H=1972.5, P＜005). The elderly group and the middle-aged group had a significantly lower proportion of patients with recurrence than the young group (both P＜0.05). There were no significant differences in local complications between the three groups (all P＞0.05), and as for systemic complications, compared with the young group, the elderly group had a significantly higher proportion of patients with pneumonia (3.9% vs 2.2%, P＜0.05), acute kidney injury (AKI) (6.2% vs 2.5%, P＜0.05), or multiple organ dysfunction syndrome (MODS) (7.8% vs 4.0%, P＜0.05). Compared with the middle-aged group and the young group, the elderly group had a significantly lower proportion of cured patients (67.4% vs 76.3% vs 820%, P＜0.05) and a significantly higher proportion of patients with improvement (23.3% vs 147%/12.7%, P＜0.05). The elderly group and the middle-aged group had a significantly higher proportion of patients withdrawn from treatment than the young group (8.5%/5.9% vs 3.4%, P＜0.05). There was 1 death in the elderly group (0.8%), 9 deaths in the middle-aged group (1.6%), and 16 deaths in the young group (0.5%), and there was no significant difference between the three groups (P＞0.05). There were no significant differences in length of hospital stay and hospital costs between the three groups (P＞0.05). ConclusionAP patients aged ≥80 years are mainly female and are often caused by biliary factors, and they are likely to develop the complications such as pneumonia, AKI, and MODS.

Value of neutrophil-lymphocyte ratio combined with apolipoprotein A-I level in predicting the severity of acute pancreatitis in the early stage after admission / 临床肝胆病杂志

ObjectiveTo investigate the value of neutrophil-lymphocyte ratio (NLR) combined with apolipoprotein A-I (ApoA-I) level in predicting the severity of acute pancreatitis (AP). MethodsA retrospective analysis was performed for 460 patients with AP who were admitted to The Affiliated Hospital of Southwest Medical University from January 2015 to December 2019, among whom 250 had mild acute pancreatitis (MAP), 166 had moderate-severe acute pancreatitis, and 44 had severe acute pancreatitis (SAP). Related clinical data were collected, including basic information, laboratory markers (neutrophil count, lymphocyte count, serum triglyceride, serum total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, ApoA-I, and apolipoprotein B), and scores (Ranson, BISAP, and MCTSI). A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups; a logistic regression analysis was performed for the variables with statistical significance in univariate analysis; a Spearman correlation analysis was performed to investigate the correlation between data. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of indices, and MedCalc software was used to investigate whether there was a significant difference in diagnostic efficiency. ResultsThere were significant differences in NLR and ApoA-I level between the groups with different severities of AP (χ2= 64.124, F=40.277, P＜0.001). On admission, NLR was positively correlated with Atlanta grading, Ranson score, MCTSI score, and BISAP score (r=0.370, 0.129, 0.260, and 0.122, all P＜0.05), and ApoA-I level was negatively correlated with Atlanta grading, Ranson score, MCTSI score, and BISAP score (r=-0.358, -0.220, -0.297, and -0.251, all P＜0.05). NLR was an independent risk factor for non-MAP (odds ratio ［OR］=1.104, 95% confidence interval ［CI］: 1.070-1.140, P＜0.001), while ApoA-I was an independent protective factor against non-MAP (OR=0.138, 95% CI: 0.070-0.264, P＜0.001); NLR was an independent risk factor for SAP (OR=1.163, 95% CI: 1.107-1.222, P＜0.001), while ApoA-I was an independent protective factor against SAP (OR=0013, 95% CI: 0.003-0.056, P＜0.001). NLR had an area under the ROC curve (AUC) of 0.700 (95% CI: 0.656-0.742, P＜0.001) in predicting non-MAP; ApoA-I had an AUC of 0.684 (95% CI: 0.640-0.726, P＜0.001) in predicting non-MAP; NLR combined with ApoA-I had an AUC of 0.748 (95%CI: 0.706-0.787, P＜0.001) in predicting non-MAP. NLR combined with ApoA-I had a better value than NLR or ApoA-I alone in predicting non-MAP (Z=3.439 and 2.462, both P＜0.05). NLR had an AUC of 0.752 (95% CI: 0.710-0.791, P＜0.001) in predicting SAP; ApoA-I had an AUC of 0.797 (95% CI: 0.757-0.833, P＜0.001) in predicting SAP; NLR combined with ApoA-I had an AUC of 0.857 (95% CI: 0.822-0.888, P＜0.001) in predicting SAP. NLR combined with ApoA-I had a better value than NLR or ApoA-I alone in predicting SAP (Z=3.171 and 2.630, both P＜0.05). ConclusionNLR combined with ApoA-I can be used as a good indicator for predicting the severity of AP in the early stage after admission.

Evaluation of the efifcacy of endoscopic tissue adhesive injection in treatment of gastric varices bleeding from liver cirrhosis / 中国内镜杂志

Astract: Objective To explore the efifcacy and safety of endoscopic tissue adhesive injection in treatment of gastric variceal bleeding from liver cirrhosis.Methods Object of study are 92 cirrhotic patients (72 male/20 female) in hospital, who had been diagnosed with gastric varices bleeding from June 2014 to May 2016. Child-Pugh score at presentation for cirrhotic patients was A-28; B-36; C-28. According to endoscopic classiifcation of gastric varices, GEV1 were detected in 80 patients, GEV2 in 12. All patients were treated with endoscopic hypertonic glucose tissue adhesive ‘sandwich’ injection.Result Successful injection rate was 100.0% in 92 patients, among which 40 patients had accepted emergency endoscopic treatment and the immediate hemostasis rate was 100.0%. 65 patients were Having gastroscope review after the injection six months, 22 patients were significantly effective, accounting for 33.8%; 38 patients were effective, accounting for 58.4%; 5 patients were invalid, accounting for 7.7%. All the patients were followed up in 1 to 24 months. The late-rebleeding rate was 2.2%. None of them were having early-rebleeding or dead; Complications the incidence of rebleeding rate which caused by removing the needles which trapped in the varices was 2.2%. The incidence of chest pain rate was 4.3%, the bloating rate was 6.5% and the ulceration rate was 15.2%. There was no complications like fever, infection, stomachache, embolism and so on.Conclusion With low rebleeding rate and light side-effect, endoscopic tissue adhesive injection in the treatment of gastric variceal bleeding caused by cirrhosis portal hypertension has really good effect.
