Acute kidney injury in patients hospitalized with COVID-19 in Wuhan, China: a single-center retrospective observational study / 南方医科大学学报

OBJECTIVE@#To assess the predictors and outcomes of acute kidney injury (AKI) among patients with coronavirus disease 2019 (COVID-19).@*OBJECTIVE@#This retrospective observational study was conducted among patients with a confirmed diagnosis of COVID-19 admitted to Hankou Hospital between January, 5 and March 8, 2020. We evaluated the association of AKI with the demographic and biochemical parameters and clinical outcomes of the patients using univariate regression analysis.@*OBJECTIVE@#Atotal of 287 COVID-19 patients, including 55 with AKI and 232 without AKI, were included in the analysis. Compared with the patients without AKI, the patients with AKI were older, predominantly male, and were more likely to have hypoxia and pre-existing hypertension and cerebrovascular diseases. The patients with AKI also had higher levels of white blood cells, D-dimer, aspartate aminotransferase, total bilirubin, creatine kinase, lactate dehydrogenase, procalcitonin, C-reactive protein, a higher prevalence of hyperkalemia, lower lymphocyte counts, and higher chest computed tomographic scores. The incidence of stage 1 AKI was 14.3% and that of stage 2 or 3 AKI was 4.9%. The patients with AKI had much higher mortality rate than those without AKI.@*OBJECTIVE@#AKI is an important complication of COVID-19. An older age, a male gender, multiple pre- existing comorbidities, lymphopenia, increased infection indicators, elevated D-dimer, and impaired heart and liver functions are all potential risk factors ofAKI. COVID- 19 patients with AKI that progresses into stages 2 or 3 AKI have a high mortality rate. Prevention of AKI and monitoring kidney function is critical in the care of COVID-19 patients.

Clinical characteristics and outcomes of adult critically ill patients with COVID-19 in Honghu, Hubei Province / 南方医科大学学报

OBJECTIVE@#To explore the clinical characteristics and outcomes of adult critically ill patients with COVID-19 and identify the risk factors correlated with in-hospital deaths.@*METHODS@#This study was conducted among 20 confirmed adult cases of COVID-19 in the Intensive Care Unit (ICU) of Honghu People's Hospital in Jingzhou City, Hubei Province. According to the final outcome, the patients were divided into survivor group and death group with 10 patients each. The demographic data, clinical manifestations and signs, laboratory findings, treatment measures and clinical outcomes were obtained from electronic medical records to compare the clinical characteristics and outcomes between the two groups. Univariate logistic analysis was used to analyze the risk factors associated with in-hospital death.@*RESULTS@#The mean age of patients with confirmed COVID-19 was 70 ± 12 years, and 40% of them were male. The patients were admitted to ICU 11 ± 9 days after symptom onset. The most common symptoms on admission were cough (19 cases), fatigue or myalgia (18 cases), fever (17 cases) and dyspnea (16 cases). Eleven (55%) of the patients had underlying diseases, among which hypertension was the most common (11 cases), followed by cardiovascular disease (4 cases) and diabetes (3 cases). Six (30%) of the patients received invasive mechanical ventilation and continued renal replacement therapy but eventually died. Acute cardiac injury was the most common complication (19 cases). Half of the patients died between the 2nd and 19th day after ICU admission. Compared with dead patients, the surviving patients had a lower average body weight (61.70±2.36 68.60±7.15 kg, =0.01) and a higher Glasgow Coma Index (14.69 ± 0.70 12.70 ± 2.45, =0.03), and were less likely to develop shock (2 10, =0.001) or acute respiratory distress syndrome (2 10, =0.001).@*CONCLUSIONS@#Critically ill patients with COVID-19 are generally older. A higher body weight and a lower lymphocyte count are potentially associated with a greater likeliness of fatality in ICU patients with COVID-19.

Correlation Between the Total Serum IgE Level of Asthmatic Diseases in Infants and the Development of Asthma / 药物流行病学杂志

Objective:To study the total serum IgE level of infant's asthmatic diseases in acute attacks and its effect on the development of wheezing.Method:The serum IgE levels of 964 children(younger than two years old)diag- nosed as asthmatic bronchitis or bronehiolitis were measured by immune dispersion nephelometer.Result:78.9% childrens had high E levels(females took up 25.9% and males,74.1%),asthmatic bronchitis accounted for 92.3% of the total and bronehiolitis,60.3%.Of the 328 infants involved in our research,76 were diagnosed as asthma at last,which accoun- ted for 23.2%.Conclusion:78.9% infants had a high level of IgE in an acute phase.There was a prominent relativity be- tween IgE and the development of asthma.The increased IgE level of asthmatic bronchitis was obviously higher than that of the bronchiolitis.There appeared to be a connection between the IgE level and the occurrence of asthmatic bronchitis to- gether with the development of asthma.
