RESUMO

Objective:To investigate the relationship between the changes of inflammatory cytokine levels and prognosis of patients with critical coronavirus disease 2019 (COVID-19) undergoing invasive mechanical ventilation (IMV).Methods:A retrospective study was conducted. The clinical date of critical COVID-19 patients undergoing IMV who were hospitalized in Wuhan Union Hospital, Tongji Medical College of Huazhong University of Science and Technology from February 4th to March 25th in 2020 were collected. At the same time, the inflammatory cytokine levels including interleukins (IL-2, IL-4, IL-6, IL-10) and tumor necrosis factor-α (TNF-α) at 48 hours before IMV and 48 hours after IMV of all the patients, as well as the 48 hours after weaning or right before death were recorded. Multivariate unconditional Logistic regression analysis was used to screen the independent risk factors of death during hospitalization.Results:Among the 43 patients, 13 patients improved and 30 died. Compared with the survival group, the patients in the non-survival group were older (years old: 67.6±7.3 vs. 58.5±11.9, P < 0.05), with higher rates of hypertension, diabetes and coronary heart disease (53.3% vs. 15.4%, 63.3% vs. 23.1%, 26.7% vs. 0%, all P < 0.05), and the time from onset to admission to hospital, admission to ICU and IMV were longer (days: it was 9.17±5.00 vs. 5.07±2.49, 17.10±7.11 vs. 12.23±5.05, and 17.90±7.46 vs. 12.61±5.60, respectively, all P < 0.05). The IL-6 and TNF-α levels on 48 hours after IMV in the non-survival patients increased significantly as compared with those before 48 hours and the surviving patients. Especially, the IL-6 levels increased significantly as compared with those at 48 hours after IMV and 48 hours after weaning in the surviving patients [ng/L: 800.00 (194.25, 2 000.00) vs. 22.03 (6.66, 28.21), 3 204.00 (1 264.88, 5 000.00) vs. 5.00 (3.98, 12.27), both P < 0.01]. The IL-10 level before death in the non-survival patients increased significantly as compared with that at 48 hours after weaning in the surviving patients [ng/L: 55.89 (26.07, 100.14) vs. 3.53 (2.76, 12.36), P < 0.05]. There were no significant differences in the levels of IL-2 and IL-4 between the two groups at every time point. The variables of age, basic diseases, the IL-6 level after IMV were included in the multivariate unconditional Logistic regression analysis, which showed that age [odds ratio ( OR) = 0.821, 95% confidence interval (95% CI) was 0.695-0.968], hypertension ( OR = 0.027, 95% CI was 0.002-0.378), diabetes mellitus ( OR = 0.054, 95% CI was 0.005-0.611), coronary heart disease ( OR = 0.042, 95% CI was 0.002-0.968) and the IL-6 level after IMV ( OR = 0.902, 95% CI was 0.819-0.994) were independent risk factors for death during hospitalization in patients with critical COVID-19 undergoing IMV (all P < 0.05). Conclusions:The levels of inflammatory cytokine including IL-6, IL-10, and TNF-α increased significantly with aggravation in critical COVID-19 patients undergoing IMV, especially IL-6. IL-6 was an independent risk factor for death of critical COVID-19 patients undergoing IMV.

RESUMO

Objective To study the epidemiological characteristics of the acute toxicosis cases in a general hospital of a metropolis. Methods The prospective study was performed from Jan. 1st, 2005 to Dec. 31st, 2006 in acute toxicosis patients admitted during that period. The data analyzed included sex, age, occupation, onset time, poisoning cause, variety of poisons, way of poisoning, emergency diagnosis, emergency treatment, etc. Results There were 315 poisoning patients treated during the study period, accounting for 2.33‰ of the total patients visiting in the emergency department. Among these poisoning patients, the sex ratio (males vs females) was 1∶0.84. The age of most of the patients ranged from 20 to 29 (35.9%) years old. Alcohol was the major cause of poisoning (38.4%), followed in order by poisoning due to drugs (20.6%), food poisoning (18.1%), chemical poisoning (10.2%) and pesticide poisoning (5.7%). There was predominant time of the occurrence of poisoning in a year, but it was more frequent in January, February, June, July, November and December. 85.1% of patients were poisoned by oral route. The occupation of patients was mainly technical personnel (21.0%), followed in order by farmers and the laborers, self-employed businessmen, persons taking care of household chores and the unemployed, etc. 98.1% of patients survived in the hospital. Mortality rate was 1.9%. Conclusions Young persons and technical personnel constitute the high-risk group of patients with poisoning. The main poisons were alcohol, drugs, food and other chemical poisons. The main route of poison intake was the digestive tract. There is no obvious seasonal regularity.
