Clinical characteristics and laboratory indicator analysis of 67 COVID-19 pneumonia patients in Suzhou, China (preprint)

Background: Sudden exacerbations and respiratory failure are major causes of death in patients with severe coronavirus disease 2019(COVID-19) pneumonia, but indicators for the prediction and treatment of severe patients are still lacking.MethodsA retrospective analysis of 67 collected cases was conducted and included approximately 67 patients with COVID-19 pneumonia who were admitted to the Suzhou Fifth People’s Hospital from January 1, 2020 to February 8, 2020. The epidemiological, clinical and imaging characteristics as well as laboratory data of the 67 patients were analyzed.ResultsThe study found that fibrinogen(FIB) was increased in 45 (65.2%) patients, and when FIB reached a critical value of 4.805 g/L, the sensitivity and specificity、DA, helping to distinguish general and severe cases, were 100% and 14%、92.9%, respectively, which were significantly better than those for lymphocyte count and myoglobin. Chest CT images indicated that the cumulative number of lung lobes with lesions in severe patients was significantly higher than that in general patients (P<0.05), and the cumulative number of lung lobes with lesions was negatively correlated with lymphocyte count and positively correlated with myoglobin and FIB. Our study also found that there was no obvious effect of hormone therapy in patients with severe COVID-19.ConclusionsBased on the retrospective analysis, FIB was found to be increased in severe patients and was better than lymphocyte count and myoglobin in distinguishing general and severe patients. The study also suggested that hormone treatment has no significant effect on COVID-19.

Clinical features of COVID-19 patients in one designated medical institutions in Chengdu, China (preprint)

OBJECTIVE: To study the clinical characteristics of patients infected with the 2019 severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) responsible for coronavirus disease (COVID-2019).METHODS: Data were collected from 20 patients admitted to the Pidu District People’s Hospital in Chengdu from January 26, 2020 to March 1, 2020 with laboratory-confirmed SARS-Cov-2 infection. Clinical data were collected using the World Health Organization (WHO) nCoV CASE RECORDFORM Version 1.2 28JAN2020, which includes parameters such as: temperature, epidemiological characteristics, social network, history of exposure, and incubation period. If information was unclear, the team reviewed the original data and contacted patients directly if necessary.RESULTS: The median age of the 20 COVID-19 infected patients studied was 42.5 years. In this cohort, four patients became severely ill and one deteriorated rapidly during treatment. This patient was transferred to another medical center with an intensive care unit (ICU) for treatment. This patient died after admission to the ICU. Two of the twenty patients remained positive SARS-Cov-2 more than three weeks, and they were quarantined in a medical facility without medication. According to our analysis, all of the studied cases were infected by human-to-human transmission due to the lack of protective measures; transmission through contact within families requires confirmation. The most common symptoms at onset of illness were fever in 13 (65%) patients, cough in 9 (45%), headache in 3 (15%), fatigue in 6 (30%), diarrhea in 3 (15%), and abdominal pain in 2 (10%). Six patients (30%) developed shortness of breath upon admission. The median time from exposure to onset of illness was6.5 days (interquartile range 3.25–9 days), and from the onset of symptoms to first hospital admission was 3.5 (1.25–7) days.CONCLUSION: Compared with patients infected with SARS-Cov-2 in Wuhan (up to the end of February 2020), the symptoms of patients in one hospital in Chengdu, Sichuan Province, were relatively mild and patients were discharged from the hospital after only a short stay. However, the fasting blood glucose of the infected individuals was found to be slightly elevated because of the state of emergency. The dynamic changes in lymphocyte levels can predict disease status of COVID-19. They are also suggestive of changes in mean platelet volume during disease progression. This suggests that the patients had mild cases of COVID-19. However, because there is no effective drug treatment for COVID-19, it is important to detect and identify severe cases from mild cases early.

Clinical characteristics and laboratory indicator analysis of 69 COVID-19 pneumonia patients in Suzhou, China (preprint)

Background Sudden exacerbations and respiratory failure are major causes for the death of severe COVID-19 pneumonia patient and but now the detection and treatment of severe patients is still lack. Methods A retrospective analysis is conducted on 69 collected cases, which are about 69 patients with COVID-19 pneumonia who were admitted to the Suzhou Fifth People’s Hospital from January 1, 2020 to February 8, 2020. Their epidemiological, clinical and imaging characteristics as well as laboratory data of the 69 patients were analyzed. Results The study found fibrinogen increased in 45 (65.2%) patients and when the fibrinogen takes a critical value of 4.805 g/L, the sensitivity and specificity, helping distinguish general and severe classification, are 100% and 14%, respectively, which are significantly better than lymphocyte and myoglobin. Chest CT images indicate that the cumulative number of lung lobes in severe patients were significantly higher than that in general patients (P＜0.05) and the cumulative number of lung lobes in the lesions was negatively correlated with lymphocyte, and positively correlated with myoglobin and fibrinogen. Our study also found that there is no obvious effect of hormone therapy in severe patients with COVID-19. Conclusions Based on the retrospective analysis, the fibrinogen were found increased in severe patients and were better than lymphocyte and myoglobin in respect of distinguishing general and severe patients. And the study also suggested hormone treatment has no significant effect on COVID-19.
