RESUMO
Objective:To investigate the relationship between previous bleeding history and poor prognosis of patients with acute upper gastrointestinal bleeding.Methods:This study was a prospective multicentre real-world study (Acute Upper Gastrointestinal Real-word study, AUGUR study). The data of patients with UGIB who were admitted to the emergency department of 20 tertiary hospitals in China from June 30, 2020 to February 10, 2021 were collected. According to the number of previous bleeding history, the patients were divided into three groups (0 time, 1-3 times, and≥4 times). Based on the patient’s demographic data, clinical characteristics, laboratory data, treatment, and outcomes, univariate and logistic regression analysis were performed to investigate the correlation between the number of previous bleeding and the 90-day mortality and rebleeding of patients with gastrointestinal bleeding.Results:A total of 1 072 patients with acute UGIB were included in this study. The all-cause mortality and rebleeding rate of all patients were 10.9% (117/1 072) and 11.8% (129/1 072), respectively. Among them, 712 patients (66.42%) had no previous bleeding, 297 patients (27.71%) had previous bleeding 1-3 times, and 63 patients (5.88%) had previous bleeding≥4 times. In univariate analysis, age, vital signs and consciousness on admission, history of liver cirrhosis, onset with hematemesis, admission hemoglobin, varicose veins bleeding, peptic ulcer bleeding, red blood cell infusion, tracheal intubation and the use of vasopressors after admission were risk factors for the 90-day mortality and rebleeding rate. Multivariate logistic regression analysis showed that patients with previous bleeding≥4 times had a higher risk of the 90-day mortality ( OR=2.17, 95% CI: 1.04-4.57, P=0.040) and rebleeding ( OR=2.32, 95% CI: 1.19-4.53, P=0.013). Conclusions:The history of previous bleeding≥ 4 times can be used as an independent risk factor for the 90-day mortality and rebleeding in patients with acute UGIB.
RESUMO
Objective:To summarize the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) infected with Delta variant, so as to provide further references for clinical diagnosis and treatment.Methods:A real-world study was conducted to analyze the characteristics of 166 COVID-19 patients infected with Delta variant at Guangzhou Eighth People’s Hospital, Guangzhou Medical University.Results:The study enrolled 5 asymptomatic cases, 123 non-severe cases (mild and moderate type), and 38 severe cases (severe and critical type). Among these patients, 69 (41.6%) were male and 97 (58.4%) were female, with a mean age of 47.0±23.5 years. Thirty-nine cases (23.5%) had received 1 or 2 doses of inactivated vaccine. The incidence of severe COVID-19 cases was 7.7% in 2-doses vaccinated patients, which was lower than that of 11.5% in 1-dose and 26.8% in unvaccinated patients. The proportion of severe cases in 2 dose-vaccinated patients was 7.7%, which was lower than that of 11.5% in 1-dose vaccinated patients and 26.8% in unvaccinated patients, but the difference was not significant ( P>0.05). The most common clinical symptom was fever (134 cases, 83.2%), and 39.1% of cases presented with high-grade fever (≥39 °C); other symptoms were cough, sputum, fatigue, and xerostomia. The proportion of fever in severe cases was significantly higher than that of non-severe cases (97.4% vs. 76.4%, P<0.01). Similarly, the proportion of severe cases with high peak temperature (≥39 ℃) () was also higher than that of non-severe cases (65.8% vs. 30.9%, P<0.01). The median minimal Cycle threshold (Ct) values of viral nucleic acid N gene and ORFlab gene were 20.3 and 21.5, respectively, and the minimum Ct values were 11.9 and 13.5, respectively. Within 48 h of admission, 9.0% of cases presented with decreased white blood cell counts, and 52.4% with decreased lymphocyte counts. The proportions of increased C-reactive protein, serum amyloid A, interleukin 6, and interleukin 10 were 32.5%, 57.4%, 65.3%, and 35.7%, respectively. The proportions of elevated C-reactive protein, serum amyloid A and interleukin-6 in severe cases were significantly higher than those in non-severe cases ( P<0.01). Logistic regression analysis showed that older age and higher peak temperature were associated with a higher likelihood of severe cases ( OR>3, 95% CI: 2-7, P<0.01). In terms of treatment, traditional Chinese medicine (TCM) was used in 97.6% of non-severe cases and 100% in severe cases. Other treatments included respiratory and nutritional support, immunotherapy (such as neutralizing antibodies and plasma of recovered patients). The median times from admission to progression to severe cases, of fever clearance, and of nucleic acid conversion were 5 days, 6 days and 19 days, respectively. No deaths were reported within 28 days. Conclusions:The symptoms of Delta variant infection in Guangzhou are characterized by a high proportion of fever, high peak temperature, long duration of fever, high viral load, a long time to nucleic acid conversion, and a high incidence of severe cases. The severe cases exhibit a higher percentage of elderly patients, a longer duration of fever and have a higher fever rate and a higher hyperthermia rate than non-severe cases. Age and hyperthermia are independent risk factors for progression to severe disease. The combination of TCM and Western medicine can control the progression of the disease effectively.
RESUMO
Objective To investigate the prognostic value of procalcitonin (PCT) and C-reactive protein (CRP) combined with sequential organ failure assessment (SOFA) score in elderly patients with sepsis induced by pulmonary infection. Methods A retrospective study was conducted. The elderly patients aged over 60 years old with sepsis induced by pulmonary infection admitted to Guangdong Provincial Hospital of Chinese Medicine from October 2015 to December 2018 were enrolled. The PCT, CRP and SOFA scores of patients within 24 hours after admission and 28-day prognosis were recorded. The patients were divided into groups according to the severity of the disease and 28-day prognosis. The differences in above parameters among all the groups were compared. Receiver operator characteristic (ROC) curve was drawn to analyze the prognostic value of the above indicators in elderly patients with sepsis induced by pulmonary infection alone or in combination. Results A total of 265 patients were enrolled in the study. According to the severity of the disease, the patients were divided into sepsis group (n = 194) and septic shock group (n = 71). According to the 28-day prognosis, the patients were divided into survival group (n = 186) and non-survival group (n = 79). Compared with the sepsis group, the PCT, CRP and SOFA scores of patients in the septic shock group were significantly increased [PCT (μg/L): 6.16 (1.94, 19.60) vs. 1.56 (0.34, 7.32), CRP (mg/L): 128.90 (54.93, 198.70) vs. 91.45 (30.15, 175.30), SOFA score: 9.0 (7.0, 12.0) vs. 4.0 (3.0, 5.0)] with significant differences (all P < 0.05). Compared with the survival group, the PCT, CRP and SOFA scores of sepsis patients in the non-survival group were significantly increased [PCT (μg/L): 4.80 (1.06, 19.60) vs. 1.82 (0.34, 7.24), CRP (mg/L): 135.20 (58.10, 225.50) vs. 91.45 (31.50, 172.53), SOFA score: 7.0 (4.0, 11.0) vs. 4.0 (3.0, 6.0)] with significant differences (all P < 0.01). ROC curve analysis showed that the area under the ROC curve (AUC) of PCT, CRP, SOFA score and CRP+PCT+SOFA score was 0.641, 0.607, 0.697, and 0.712, indicating that above parameters had certain predictive value for 28-day prognosis of elderly patients with sepsis induced by pulmonary infection, and the combined predictive value of them was the greatest with the sensitivity of 55.1% and the specificity of 80.1%. Conclusion PCT, CRP and SOFA score are commonly used to evaluate the prognosis of the elderly patients with sepsis induced by pulmonary infection, and the combination of them has higher evaluation value.
