Mechanism of action of oxidative stress in severe traumatic brain injury and its complications: recent progress / 中华创伤杂志

Severe traumatic brain injury (sTBI) is characterized by critical condition, high lethality and poor prognosis. Its development and progression will lead to the damage and death of a large number of nerve cells, eventually causing a series of serious complications. The current treatments of sTBI and its complications are not optimistic due to problems such as unclear mechanism of action, challenges in treatment, and lack of effective prevention strategies. In recent years, more research evidences have shown that oxidative stress plays an important role in the development and progression of sTBI and its related complications. Therefore, it is of great significance to clarify the relationship of oxidative stress with sTBI and its complications and to understand the way of oxidative stress participating in the development and progression of sTBI. However, relevant researches are scattered and there lacks comprehensive and systematic summaries of oxidative stress participating in sTBI and its related complications. To this end, the authors reviewed the progress of the mechanism by which oxidative stress involves in sTBI and its complications, hoping to provide references for the research, treatment and prevention of sTBI.

Objective:To investigate the correlation between serum gastrin, C-reactive protein (CRP), tumor necrosis factor α (TNF-α) and the degree of peptic ulcer bleeding.Methods:The clinical data of 90 peptic ulcer bleeding patients (test group) from April 2019 to September 2020 in Hangzhou Hospital of Zhejiang Medical and Health Group were retrospectively analyzed, including 15 cases with low-risk, 40 cases with intermediate-risk and 35 cases with high-risk of Blatchford score; 40 physical examination volunteers were selected as the control group during the same period. The serum levels of CRP and TNF-α were measured by enzyme-linked immunosorbent assay, and the serum level of gastrin was measured by radioimmunoassay. The correlation between CRP, TNF-α, gastrin and the Blatchford score was analyzed by Pearson method; the independent risk factors affecting high-risk peptic ulcer bleeding were analyzed by multivariate Logistic regression; the value of CRP, TNF-α and gastrin in predicting high-risk peptic ulcer bleeding was analyzed by the receiver operating characteristic (ROC) curve.Results:The CRP, TNF-α and gastrin in test group were significantly higher than those in control group: (19.69 ± 3.41) mg/L vs. (2.28 ± 0.64) mg/L, (26.63 ± 4.24) ng/L vs. (1.35 ± 0.31) ng/L and (149.77 ± 21.41) μg/L vs. (72.65 ± 12.39) μg/L, and there were statistical differences ( P<0.01). The hemoglobin and platelets in intermediate-risk and high-risk patients were significantly lower than those in low-risk patients: (59.21 ± 4.63) and (28.94 ± 4.69) g/L vs. (89.68 ± 5.12) g/L, (162.14 ± 12.47) and (122.05 ± 10.39) × 10 9/L vs. (213.58 ± 16.98) × 10 9/L, the indexes in high-risk patients were significantly lower than those in intermediate-risk patients, and there were statistical differences ( P<0.05); the prothrombin time, CRP, TNF-α and gastrin in intermediate-risk and high-risk patients were significantly higher than those in low-risk patients: (13.98 ± 1.29) and (16.97 ± 1.15) s vs. (11.00 ± 2.07) s, (18.87 ± 4.68) and (22.69 ± 2.96) mg/L vs. (15.45 ± 5.54) mg/L, (27.43 ± 5.05) and (31.02 ± 4.56) ng/L vs. (21.39 ± 8.54) ng/L, (140.89 ± 22.36) and (160.58 ± 25.52) μg/L vs. (121.39 ± 15.17) μg/L, the indexes in high-risk patients were significantly higher than those in intermediate-risk patients, and there were statistical differences ( P<0.05). Multivariate Logistic regression analysis result showed that hemoglobin, platelets, CRP, TNF-α and gastrin were independent risk factors for high-risk peptic ulcer bleeding ( OR = 0.224, 0.321, 3.687, 3.058 and 4.051; 95% CI 0.004 to 0.894, 0.121 to 8.547, 1.912 to 5.525, 3.012 to 10.609 and 2.012 to 7.525; P<0.05 or <0.01). Pearson correlation analysis result showed that CRP, TNF-α and gastrin were positive correlation with the Blatchford score ( r = 0.501, 0.526 and 0.542; P<0.01). ROC curve analysis result showed that the areas under the curve of CRP, TNF-α and gastrin for predicting high-risk peptic ulcer bleeding was 0.890, 0.825 and 0.901, with optimal cut-off values of 17.95 mg/L, 22.16 ng/L and 135.36 μg/L, sensitivity of 97.14%, 94.29% and 82.86%, and specificity of 80.00%, 66.67% and 86.67%. Conclusions:CRP, TNF-α and gastrin are correlated to the degree of peptic ulcer bleeding, and can be used as indexes to evaluate the bleeding degree of peptic ulcer.

Análise da utilização de inibidores de bomba de prótons em pacientes internados em um hospital universitário do interior de São Paulo / Analysis of the use of proton pump inhibitors in patients admitted to a university hospital in interior of São Paulo

Introdução: A crença de que o uso de Inibidores de Bomba de Prótons (IBPs) apresenta baixo risco de toxicidade, resultou em um aumento significativo na sua prescrição em nível mundial, esse fator juntamente com a baixa divulgação de orientações, têm contribuído para o aumento das indicações desnecessárias de inibidores de bomba de prótons em nível hospitalar, principalmente para profilaxia. Objetivo: Analisar a utilização dos inibidores de bomba de prótons em pacientes internados nas enfermarias de clínica médica de um Hospital Universitário, visando avaliar suas indicações, tempo de uso, efeitos adversos e impacto financeiro gerado pelo uso inadequado. Métodos: Foram analisados prontuários de pacientes que estiveram internados nas enfermarias de clínica médica do Hospital Municipal Universitário de Taubaté (HMUT) durante os meses de maio a julho de 2020. As indicações adequadas do uso de inibidores de bomba de prótons foram baseadas em diretrizes internacionais do American Journal of Gastroenterology e do American Society of Health-System Pharmacy. Resultados: Identificamos que 297 pacientes (79,6%) usaram inibidores de bomba de prótons em algum momento da internação. O uso desse medicamento foi adequadamente prescrito em 49,8% dos casos. Foi encontrado maior prevalência de pneumonia e diarreia nos pacientes que fizeram uso de inibidores de bomba de prótons a longo prazo. O custo anual associado as prescrições indevidas foram de R$24.736,40. Conclusão: Observamos alta prevalência de indicações incorretas dos inibidores de bomba de prótons em ambiente hospitalar, ocasionando gasto desnecessário e possíveis complicações. Faz-se necessário, portanto, elaboração de novos protocolos e maior rigidez nas indicações desses medicamentos no Hospital Municipal Universitário de Taubaté.

The controlled study of efficacy and safety of infusion of ilaprazole sodium versus esomeprazole sodium in prevention of peptic ulcer rebleeding / 中华消化杂志

Objective:To explore the efficacy and safety of intermittent infusion of ilaprazole sodium and high-dose continuous infusion of esomeprazole sodium in preventing rebleeding in patients with peptic ulcer bleeding after successful endoscopic hemostasis.Methods:This is a multi-center, interval randomized, double-blind, double-dummy, parallel controlled study. From March 3rd to June 15th, 2021, 151 patients with high risk of peptic ulcer bleeding and successfully underwent endoscopic hemostasis from 33 hospitals including the First Affiliated Hospital of Zhejiang University School of Medicine were enrolled. Patients were interval randomly divided into the trial group (74 cases) and the control group (77 cases). Patients in the trial group received intermittent intravenous infusion of ilaprazole sodium once daily (20 mg administered as a 60 min intravenous infusion on day 1, and 10 mg administered as a 30 min intravenous infusion on day 2 and 3); patients in the control group received continuous intravenous infusion of esomeprazole sodium for 72 h (esomeprazole sodium 80 mg at first dose in half an hour, and 8 mg per hour continuous intravenous infusion for 71.5 h). After intravenous infusion treatment, patients of both groups were given oral ilaprazole enteric-coated tablets, 10 mg each time, once a day for 4 d. The rebleeding rate after 72 h and within 7 d after treatment and the proportion of patients who received endoscopic retreatment or surgery due to rebleeding within 72 h after treatment were analysised based on the full analysis set (72 cases in the trial group and 75 cases in the control group); and the incidence rate of adverse reactions was observed in the two groups based on the safety analysis set (74 cases in the trial group and 76 cases in the control group). Chi-square test or Fisher exact probability test was used for statistical analysis.Results:There was no rebleeding case in the trial group within 72 h and 1 case of rebleeding within 7 d (1.39%, 1/72). In the control group, there was 1 case of rebleeding (1.33%, 1/75) within 72 h and 4 cases of rebleeding (5.33%, 4/75) within 7 d. There was no significant difference in rebleeding rate either after 72 h or within 7 d after treatment between the two groups (both P>0.05). Within 72 h of treatment, no patients in both groups needed endoscopic or surgical retreatment due to rebleeding. Adverse reactions occurred in 5 cases (6.8%, 5/74) and 6 cases (7.9%, 6/76) in the trial group and control group, respectively, which recovered spontaneously without treatment. No serious adverse reactions occurred in both groups. Conclusion:In patients with high-risk peptic ulcer bleeding with successful endoscopic hemostasis, intermittent intravenous infusion of ilaprazole sodium has similar efficacy and safety as continuous high-dose intravenous infusion of esomeprazole sodium, but the dosage of intermitten regimen is less, the administration is more convenient, and it is worthy of clinical promotion.

Correlation between the severity of peptic ulcer bleeding and Helicobacter pylori type / 中华消化杂志

Objective@#To investigate the correlation between the severity of peptic ulcer bleeding (PUB) and the serum antibody typing of Helicobacter pylori (H.pylori).@*Methods@#From January 1, 2009 to December 31, 2018, at Guangzhou First People′s Hospital, 1 444 patients diagnosed with PUB and received H. pylori serum antibody test at the same time were enrolled and divided into high-risk group (324 cases) and low-risk group (1 120 cases) according to Forrest classification, and according to recurrent bleeding, the patients were divided into recurrent bleeding group (32 cases) and non-rebleeding group (1 412 cases). Serum H. pylori specific antibodies cytotoxin-associated gene A (CagA), vacuolating cytotoxin A (VacA) and urease were detected by protein array. The correlation between H. pylori positive rate, H. pylori type, PUB and rebleeding were analyzed. Chi-square test and logistic regression analysis were used for statistical analysis.@*Results@#Among 1 444 PUB patients, there were 709 patients with gastric ulcer bleeding (GUB) and 735 patients with duodenal ulcer bleeding (DUB). Previous history of peptic ulcer disease (odds ratio (OR)=1.501, P=0.006), the maximum diameter of ulcer over 2 cm (OR=2.484, P<0.01) and H. pylori infection (OR=1.508, P=0.005) were independent risk factors of the severity of PUB. The total H. pylori positive rate was 68.49% (989/1 444), H. pylori type Ⅰ was the main type. Of which, 61.34% (549/895) were CagA and VacA double positive strains, 31.73% (284/895) were VacA single positive bacteria and CagA single positive bacteria was only 6.93% (62/895). The positive rate of H. pylori of high-risk group was higher than that of low-risk group (75.31%, 244/324 vs. 66.52%, 745/1 120), and the difference was statistically significant (χ2=8.999, P=0.004). In addition, the more serious Forrest classification, the higher the detection rate of H. pylori, and the difference was statistically significant (χ2=11.840, P=0.037). There was no significant difference in the positive rate of H. pylori between recurrent bleeding group and non-rebleeding group (81.25%, 26/32 vs. 68.20%, 963/1 412; χ2=2.469, P>0.05). According to H. pylori antibody type, H. pylori type Ⅰ infection was mainly in both high-risk group and low-risk group. The positive rate of H. pylori type Ⅰ strain of high-risk group was higher than that of low-risk group (67.28%, 218/324 vs. 60.45%, 677/1 120), and the difference was statistically significant (χ2=4.986, P=0.026). There was no statistically significant difference in the positive rate of H. pylori between GUB group and DUB group (68.41%, 485/709 vs. 68.57%, 504/735; χ2=0.005, P>0.05).@*Conclusions@#The infection of H. pylori is positively correlated with the severity of PUB, but not correlated with early ulcer rebleeding. H. pylori type Ⅰ is the main pathogenic strain of GUB and DUB, and CagA and VacA double positive strain is the most common strain.

Objective To investigate the effect of low-dose aspirin combined with rabeprazole on the healing of peptic ulcer after hemostasis with aspirin-related peptic ulcer bleeding,and to explore the independent factors associated with ulcer healing failure.Methods A total of 138 patients with acute upper gastrointestinal hemorrhage in the Department of Gastroenterology of the Second Affiliated Hospital of Fujian Medical University from June 2016 to June 2018 were enrolled.The clinical data of 138 patients with upper gastrointestinal ulcer bleeding caused by aspirin were analyzed.The patients were randomly divided into two groups.Aspirin group (n =68) received aspirin 100 mg/d plus rabeprazole 80 mg/d,while the placebo group (n =70) received rabeprazole 80 mg/d plus placebo.The patients were treated for 8 weeks.Subjects with H.pylori infection were treated with standard quadruple therapy.Follow-up endoscopy was performed at the end of 8 weeks.The primary endpoint was the healing of peptic ulcers.Results The ulcer healing rate was 79.4％ (54/68) in the aspirin group and 84.3％ (59/70) in the placebo group.There was no statistically significant difference between the two groups (x2 =0.552,P ＞ 0.05).There were 5 cases of ulcer bleeding in aspirin group and placebo group.The rehaemorrhage rate was 7.4％ (5/68) and 7.1％ (5/70),respectively.There was no statistically significant difference between the two groups(x2 =0.002,P ＞ 0.05).Among the factors affecting the healing of aspirin-associated peptic ulcer,the healing rate was significantly associated with steroid use during treatment (x2 =6.135,P =0.041) and smoking status (x2 =5.616,P =0.018).Other factors,including age,hypertension,diabetes,alcohol history,history of previous ulcer bleeding,initial Helicobacter pylori status,and ulcer location did not affect ulcer healing.Conclusion After aspirin-associated peptic ulcer bleeding,continued low-dose aspirin plus rabeprazole did not affect the healing of peptic ulcers,and the use of steroids and smoking status are independent risk factors for ulcer healing.

Massive Duodenal Bleeding after the Migration of Endovascular Coils into the Small Bowel

Among gastrointestinal emergencies, acute upper gastrointestinal bleeding remains a challenging clinical problem owing to significant patient morbidity and costs involved in management. Endoscopic hemostatic therapy is the mainstay of treatment and decreases the incidence of re-bleeding, the need for surgery, morbidity, and mortality. However, in 8%–15% of patients with upper gastrointestinal bleeding, endoscopic hemostatic therapy does not successfully control bleeding. Trans-arterial coil embolization is an effective alternative treatment for endoscopic hemostatic failure; however, this procedure can induce adverse outcomes, such as non-target vessel occlusion, vessel dissection and perforation, and coil migration. Coil migration is rare but causes severe complications, such as re-bleeding and bowel ischemia. However, in most cases, coil migration is local and involves spontaneous healing without serious complications. Here, we report the case of a patient who underwent trans-arterial coil embolization of the gastroduodenal artery with the purpose of controlling massive duodenal bleeding, resulting in a fatal outcome caused by coil migration.

Conclusion Endoscopic purse-string suture is a safe and feasible method for treatment of patients with peptic ulcer bleeding.

Factors Associated with Rebleeding in Patients with Peptic Ulcer Bleeding: Analysis of the Korean Peptic Ulcer Bleeding (K-PUB) Study

BACKGROUND/AIMS: Rebleeding is associated with mortality in patients with peptic ulcer bleeding (PUB), and risk stratification is important for the management of these patients. The purpose of our study was to examine the risk factors associated with rebleeding in patients with PUB. METHODS: The Korean Peptic Ulcer Bleeding registry is a large prospectively collected database of patients with PUB who were hospitalized between 2014 and 2015 at 28 medical centers in Korea. We examined the basic characteristics and clinical outcomes of patients in this registry. Univariate and multivariate analyses were performed to identify the factors associated with rebleeding. RESULTS: In total, 904 patients with PUB were registered, and 897 patients were analyzed. Rebleeding occurred in 7.1% of the patients (64), and the 30-day mortality was 1.0% (nine patients). According to the multivariate analysis, the risk factors for rebleeding were the presence of co-morbidities, use of multiple drugs, albumin levels, and hematemesis/hematochezia as initial presentations. CONCLUSIONS: The presence of co-morbidities, use of multiple drugs, albumin levels, and initial presentations with hematemesis/hematochezia can be indicators of rebleeding in patients with PUB. The wide use of proton pump inhibitors and prompt endoscopic interventions may explain the low incidence of rebleeding and low mortality rates in Korea.

Endoscopic Hemostatic Treatment of Peptic Ulcer Bleeding

Peptic ulcer bleeding is a common complication of peptic ulcer disease and the most common cause of upper gastrointestinal bleeding. Despite advances in drug usage and endoscopic modalities, no significant improvement is observed in the mortality rate of bleeding ulcers. The purpose of this review is to discuss various endoscopic hemostatic methods to treat peptic ulcer bleeding. Endoscopic hemostatic techniques can be classified into injection, mechanical, electrocoagulation, hemostatic powder, and endoscopic Doppler-guided hemostatic therapies (the last mentioned being a newly developed technique). Endoscopic hemostasis can be performed as mono or combination therapy using the aforementioned methods. Endoscopic hemostasis is the most important treatment for patients with peptic ulcer bleeding. Endoscopists should consider the treatment approach for peptic ulcer bleeding based on patient characteristics, the size and shape of the lesion, the endoscopist's expertise, and the resources and circumstances at each hospital. Follow-up studies are needed to evaluate the efficacy of newly developed hemostatic powder therapy and endoscopic Doppler-guided hemostasis.

Clinical control study of omeprazole and pantoprazole in treatment of peptic ulcer hemorrhage / 药物评价研究

Objective To discuss the efficacy of omeprazole and pantoprazole in treatment of peptic ulcer hemorrhage.Methods 80 patients with peptic ulcer hemorrhage were selected,they were divided into two groups randomly.The observation group (41 cases) was given pantoprazole by intravenous drip.The control group (39 cases) was given omeprazole by intravenous drip.The efficacy and safety of omeprazole and pantoprazole in treatment of peptic ulcer hemorrhage was evaluated by efficacy,pH before and after treatment,bleeding time,hospitalization and bleeding volume,and adverse reaction during treatment.Results The effective rate was 92.7％ in the observation group and 89.7％ in the control group.There was no statistical significance on effective rate between two groups.But the excellent rate of observation group was higher than that of the control group (P ＜ 0.05).Before treatment,the gastric acid was acidic.There were no statistical significance on pH value between two groups.After treatment,the pH value was increased in two groups.The pH value of observation group was higher than that of the control group (P ＜ 0.05).The hospitalization,hemostasis time and bleeding volume was shorter than that of the control group (P ＜ 0.05).During treatment,the patients given pantoprazole had less adverse reaction (P ＜ 0.05).Conclusion Pantoprazole and omeprazole are suitable for treating peptic ulcer hemorrhage.But the antacid and hemostatic effect of pantoprazole was better with high safety.It was worthy of clinical application.

Recent Developments in the Endoscopic Treatment of Patients with Peptic Ulcer Bleeding

Peptic ulcer bleeding is an internal medical emergency. Endoscopic hemostasis has been shown to improve the survival rate of patients with peptic ulcer bleeding. Although the established hemostatic modalities, including injection, thermal therapy, and mechanical therapy, are effective in controlling peptic ulcer bleeding, hemostasis can be difficult to achieve in some cases. As a result, recent, new endoscopic hemostatic modalities, including over-the-scope clips, topical hemostatic sprays, and endoscopic ultrasonography-guided angiotherapy, have been developed.

Optimal Operational Definition of Patient with Peptic Ulcer Bleeding for Big Data Analysis Using Combination of Clinical Characteristics in a Secondary General Hospital / 대한소화기학회지

BACKGROUND/AIMS: Peptic ulcer bleeding (PUB) is the most common cause of upper gastrointestinal bleeding in Korea but there has been no research done using big data. This study evaluates the optimal operational definition (OD) for big data research by analyzing clinical characteristics of PUB. METHODS: We reviewed the clinical characteristics of 92 patients with PUB confirmed on endoscopy in Wonkwang University Sanbon Hospital (January 2013 to December 2014). We calculated sensitivity and positive predictive value (PPV) to detect confirmed PUB patients using ODs developed by combining clinical features of patients with PUB. RESULTS: The mean patient age was 63 years. Men had higher prevalence of PUB than women. Bleeding gastric ulcer was proportionately common in the age range of 40s to 60s in men, while a significantly higher rate of bleeding occurred in women older than 70s. The rate of drug-induced ulcer was 28.2%, whereas the prevalence of Helicobacter pylori was 47.8%. Among the hospitalized patients with diagnostic code of PUB, we ruled out patients with endoscopic removal of gastric adenoma or peritonitis, and selected patients who had been administered intravenous proton pump inhibitor. The sensitivity in this setting was 82.6%, and PPV was 88.4%. CONCLUSIONS: PUB was more common in older patients, and there was a clear gender difference in gastric ulcer bleeding by age. With a proper OD using PUB diagnostic codes, we can identify true patients with sufficiently high sensitivity and PPV.

Diagnosis and Management of Peptic Ulcer Bleeding / 대한내과학회지

Despite the generally declining trend in the incidence of peptic ulcers, peptic ulcer bleeding remains a prevalent and clinically significant condition. Additionally, despite the development of therapeutic endoscopy and acid-suppressive therapy, the overall mortality associated with peptic ulcer bleeding has remained at about 6% to 14%. Management of acute peptic ulcer bleeding requires prompt resuscitation, risk assessment, early endoscopic evaluation, and early initiation of pharmacotherapy. Advances in therapeutic endoscopic techniques and antisecretory therapies in the past few decades have reduced the incidence of recurrent bleeding and the mortality rate associated with this disease. Strategies to prevent recurrence have been defined for various causes of peptic ulcer bleeding. This article reviews the current diagnosis and management of acute peptic ulcer bleeding.
