ABSTRACT
Background: Coronavirus disease 2019 (COVID-19) has been a global threat that pushes healthcare to its limits. Hypertension is one of the most common risk factors for cardiovascular complications in COVID-19 and is strongly associated with disease severity and mortality. To date, clinical mechanisms by which hypertension leads to increased risk in COVID-19 are still unclear. Furthermore, additional factors might increase these risks, such as the consideration of age and sex, which are of interest when in search of personalized treatments for hypertensive COVID-19 patients. Methods: We conducted a retrospective cohort study of 543 COVID-19 patients in seven provinces of China to examine the epidemiological and clinical characteristics of COVID-19 in this population and to determine risk factors of hypertensive COVID-19 patients. We also used univariable and multivariable logistic regression methods to explore the risk factors associated with hypertensive COVID-19 patients in different age and sex subgroups. Results: Among the enrolled COVID-19 patients, the median age was 47 years (interquartile range (IQR) 34.0-57.0), and 99 patients (18.23%) were over 60 years old. With regard to comorbidities, 91 patients (16.75%) were diagnosed with hypertension, followed by diabetes, coronary disease, and cerebrovascular disease. Of the hypertensive COVID-19 patients, 51 (56.04%) were male. Multivariable analysis showed that old age, comorbid diabetes or coronary heart disease on admission, increased D-dimer, increased glucose, and decreased lymphocyte count were independent risk factors associated with hypertensive COVID-19 patients. Elevated total bilirubin (odds ratio [OR]: 1.014, 95% confidence interval [CI]: 0.23-1.05; p = 0.043) and triglycerides (OR: 1.173, 95% CI: 0.049-1.617; p = 0.007) were found to be associated with elderly hypertensive COVID-19 patients. In addition, we found that decreased lymphocytes, basophil, high-density lipoprotein, and increased fibrinogen and creatinine were related to a higher risk of disease severity in male patients. The most common abnormal clinical findings pertaining to female hypertensive COVID-19 patients were hemoglobin, total bile acid, total protein, and low-density lipoprotein. Conclusions: Factors associated with increased risk of hypertensive COVID-19 patients were identified. Results to the different age and sex subgroups in our study will allow for better possible personalized care and also provide new insights into specific risk stratification, disease management, and treatment strategies for COVID-19 patients with hypertension in the future.

OBJECTIVE: To evaluate the clinical efficacy of Xuebijing combined with human immunoglobulin for the treatment of severe and critically ill patients with coronavirus disease 2019 (COVID-19). METHODS: A retrospective study was conducted. The clinical data of 65 patients with severe and critical COVID-19 admitted to Chongqing Public Health Medical Center and Chongqing Three Gorges Central Hospital from January 2020 to March 2020 during the period of supporting to combat COVID-19 by the medical team of the Second Affiliated Hospital of Chongqing Medical University and Chongqing Hospital of Traditional Chinese Medicine were analyzed. According to different treatment regimens, patients were divided into conventional treatment group (conventional antivirus, anti-infection and symptomatic support treatments), Xuebijing group (Xuebijing was applied to patients with elevated inflammatory cytokines) and combination group (Xuebijing combined with human immunoglobulin, human immunoglobulin was applied to patients with low immunity indicated by monitoring results of lymphocytes and their subsets). The improvement of blood routine examination, blood gas analysis, myocardial enzyme spectrum, liver and kidney function, lymphocytes and their subsets and cytokines as well as severity score in three groups before and after treatment were observed. Kaplan-Meier method was used to draw the 28-day survival curve of each group, and the cumulative survival rate among the groups was compared. RESULTS: Among the 65 severe and critically ill COVID-19 patients, only 20 patients received conventional treatment, 22 patients were treated with Xuebijing based on conventional treatment, and 23 patients were treated with Xuebijing combined with human immunoglobulin based on conventional treatment. Before treatment, CD4+ T cell count in combination group was higher than other two groups, and interleukin-6 (IL-6) was lower than other two groups, while other indicators showed no statistically significant differences among the three groups, suggesting that the baseline of the three groups was relatively balanced before treatment. The patients in the conventional treatment group were relieved after treatment, and it was characterized by that the acute physiology and chronic health evaluation II (APACHE II) score and lactate dehydrogenase (LDH) were significantly lower than those before treatment [APACHE II score: 5.20±2.74 vs. 6.20±1.93, LDH (µmol×s-1×L-1): 4.1±1.0 vs. 4.7±0.9, both P < 0.01], but there was still liver damage, which was manifested as higher aspartate aminotransferase (AST) than that before treatment [U/L: 30.5 (23.8, 41.5) vs. 21.0 (17.0, 34.0), P < 0.05]. In Xuebijing group, the respiratory function and immunity of patients were improved after treatment, and the improvement degree of the ratio of CD4+ T cell was more significant than that in the conventional treatment group (4.86±6.31 vs. -0.95±12.38, P < 0.05). However, the patients still lived with an "inflammatory storm" and liver damage after treatment. It was shown that IL-4 was significantly higher than that before treatment (ng/L: 2.57±1.15 vs. 1.92±1.04, P < 0.05), while albumin (ALB) decreased significantly compared with before treatment [g/L: 33.0 (30.5, 35.6) vs. 36.2 (32.1, 41.4), P < 0.01]. While the treatment of Xuebijing combined with human immunoglobulin could improve patients' respiratory function and enhance their immunity more effectively, it was shown that arterial partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2), T lymphocyte count, ratio of CD4+ T cell, CD4+ T cell count, CD8+ T cell count and CD4+/CD8+ ratio were significantly higher than those before treatment, while ALB, IL-6, APACHE II score and sequential organ failure assessment (SOFA) score were significantly lower than those before treatment. T lymphocyte count, the ratio of CD4+ T cell and IL-6 in combination group were improved more significantly than those in conventional treatment group and Xuebijing group [T lymphocyte count (×109/L): 310.68±359.28 vs. 46.54±240.01, 81.59±256.76; ratio of CD4+ T cell: 14.53±14.49 vs. -0.95±12.38, 4.86±6.31; IL-6 (ng/L): -25.53±39.05 vs. -1.75±5.45, 12.78±44.81], PaO2/FiO2 was improved more significantly as compared with the Xuebijing group [mmHg (1 mmHg = 0.133 kPa): 146.31±109.73 vs. 59.41±87.70], and the differences were statistically different (all P < 0.05). CONCLUSIONS: The combination of Xuebijing and human immunoglobulin for the treatment of patients with COVID-19 can improve patients' respiratory function, reduce "inflammatory storm", enhance immunity, and alleviate severity of patients' condition.

METHODS: In this multicenter retrospective study, patients with COVID-19 in China were included and classified into two groups according to whether they were complicated with diabetes or not. Demographic symptoms and laboratory data were extracted from medical records. Univariable and multivariable logistic regression methods were used to explore the risk factors. RESULTS: 538 COVID-19 patients were finally included in this study, of whom 492 were nondiabetes and 46 were diabetes. The median age was 47 years (IQR 35.0-56.0). And the elderly patients with diabetes were more likely to have dry cough, and the alanine aminotransferase, lactate dehydrogenase, Ca, and mean hemoglobin recovery rate were higher than the other groups. Furthermore, we also found the liver and kidney function of male patients was worse than that of female patients, while female cases should be paid more attention to the occurrence of bleeding and electrolyte disorders. Moreover, advance age, blood glucose, gender, prothrombin time, and total cholesterol could be considered as risk factors for COVID-19 patients with diabetes through the multivariable logistic regression model in our study. CONCLUSION: The potential risk factors found in our study showed a major piece of the complex puzzle linking diabetes and COVID-19 infection. Meanwhile, focusing on gender and age factors in COVID-19 patients with or without diabetes, specific clinical characteristics, and risk factors should be paid more attention by clinicians to figure out a targeted intervention to improve clinical efficacy worldwide.

BACKGROUND: A worldwide outbreak of coronavirus disease (COVID-19), since 2019, has brought a disaster to people all over the world. Many researchers carried out clinical epidemiological studies on patients with COVID-19 previously, but risk factors for patients with different levels of severity are still unclear. METHODS: 562 patients with laboratory-confirmed COVID-19 from 12 hospitals in China were included in this retrospective study. Related clinical information, therapies, and imaging data were extracted from electronic medical records and compared between patients with severe and non-severe status. We explored the risk factors associated with different severity of COVID-19 patients by logistic regression methods. RESULTS: Based on the guideline we cited, 509 patients were classified as non-severe and 53 were severe. The age range of whom was 5-87 years, with a median age of 47 (IQR 35.0-57.0). And the elderly patients (older than 60 years old) in non-severe group were more likely to suffer from fever and asthma, accompanied by higher level of D-dimer, red blood cell distribution width and low-density lipoprotein. Furthermore, we found that the liver and kidney function of male patients was worse than that of female patients in both severe and non-severe groups with different age levels, while the severe females had faster ESR and lower inflammatory markers. Of major laboratory markers in non-severe cases, baseline albumin and the lymphocyte percentage were higher, while the white blood cell and the neutrophil count were lower. In addition, severe patients were more likely to be accompanied by an increase in cystatin C, mean hemoglobin level and a decrease in oxygen saturation. Besides that, advanced age and indicators such as count of white blood cell, glucose were proved to be the most common risk factors preventing COVID-19 patients from aggravating. CONCLUSION: The potential risk factors found in our study have shown great significance to prevent COVID-19 patients from aggravating and turning to critical cases during treatment. Meanwhile, focusing on gender and age factors in groups with different severity of COVID-19, and paying more attention to specific clinical symptoms and characteristics, could improve efficacy of personalized intervention to treat COVID-19 effectively.

Objective To explore the optimal therapy time for the treatment of severe coronavirus disease 2019(COVID-19)by traditional Chinese medicine(TCM)and its influence on the therapeutic effect and prognosis. Methods The clinical data,laboratory findings,and outcomes of 64 patients with severe COVID-19 treated with TCM and western medicine in Chongqing from January 20,2020, to March 11,2020 were retrospectively analyzed.Patients were divided into early intervention group[TCM was initiated within 3 days (including day 3) after the first diagnosis of severe type/critical type COVID-19]and late intervention group[TCM was initiated after 7 days (including day 7) after the first diagnosis of severe type /critical type COVID-19].The changes in clinical parameters during the course of disease were compared between the two groups. Results On day 14,the oxygenation index was 292.5(252.0,351.0)mmHg in the early intervention group,which was significantly higher than that in the late intervention group [246.0(170.0,292.5)mmHg](P=0.005).The length of hospital stay [(18.56±1.11)d vs.(24.87±1.64)d,P=0.001],duration of ICU stay [(14.12±0.91)d vs.(20.00±1.53)d,P=0.000] and time to negativity [(16.77±1.04)d vs.(22.48±1.66)d,P=0.001] in the early intervention group were significantly shorter than those in the late intervention group.The intubation rate(7.3%)in the early intervention group was significantly lower than that in the late intervention group(30.4%)(P=0.028). Conclusion Early TCM therapy within three days after a diagnosis of severe COVID-19 can shorten the length of hospital stay,duration of ICU stay,and time to negativity and decrease intubation rate.
