ABSTRACT

Objective: The scientific community knows little about the long-term influence of coronavirus disease 2019 (COVID-19) on olfactory dysfunction (OD). With the COVID-19 pandemic ongoing worldwide, the risk of imported cases remains high. In China, it is necessary to understand OD in imported cases. Methods: A prospective follow-up design was adopted. A total of 11 self-reported patients with COVID-19 and OD from Xi'an No. 8 Hospital were followed between August 19, 2021, and December 12, 2021. Demographics, clinical characteristics, laboratory and radiological findings, and treatment outcomes were analyzed at admission. We surveyed the patients via telephone for recurrence and sequelae at the 1-, 6-, and 12-month follow-up. Results: Eleven patients with OD were enrolled; of these, 54.5% (6/11) had hyposmia and 45.5% (5/11) had anosmia. 63.6% (7/11) reported OD before or on the day of admission as their initial symptom; of these, 42.9% (3/7) described OD as the only symptom. All patients in the study received combined treatment with traditional Chinese medicine and Western medicine, and 72.7% (8/11) had partially or fully recovered at discharge. In terms of OD recovery at the 12-month follow-up, 45.5% (5/11) reported at least one sequela, 81.8% (9/11) had recovered completely, 18.2% (2/11) had recovered partially, and there were no recurrent cases. Conclusions: Our data revealed that OD frequently presented as the initial or even the only symptom among imported cases. Most OD improvements occurred in the first 2 weeks after onset, and patients with COVID-19 and OD had favorable treatment outcomes during long-term follow-up. A better understanding of the pathogenesis and appropriate treatment of OD is needed to guide clinicians in the care of these patients.

ABSTRACT

AIMS: In order to determine acute cardiac involvement in patients with COVID-19, we quantitatively evaluated tissue characteristics and mechanics by non-invasive cardiac magnetic resonance (CMR) in a cohort of patients within the first 10 days of the onset of COVID symptoms. METHODS AND RESULTS: Twenty-five patients with reverse transcription polymerase chain reaction confirmed COVID-19 and at least one marker of cardiac involvement [cardiac symptoms, abnormal electrocardiograph (ECG), or abnormal cardiac biomarkers] and 25 healthy age- and gender-matched control subjects were recruited to the study. Patients were divided into those with elevated (n = 8) or normal TnI (n = 17). There were significant differences in global longitudinal strain among patients who were positive and negative for hs-TnI, and controls [-12.3 (-13.3, -11.5)%, -13.1 (-14.2, -9.8)%, and -15.7 (-18.3, -12.7)%, P = 0.004]. Native myocardial T1 relaxation times in patients with positive and negative hs-TnI manifestation (1169.8 ± 12.9 and 1113.2 ± 31.2 ms) were significantly higher than the normal (1065 ± 57 ms) subjects, respectively (P < 0.001). The extracellular volume (ECV) of patients who were positive and negative for hs-TnI was higher than that of the normal controls [32 (31, 33)%, 29 (27, 30)%, and 26 (24, 27.5)%, P < 0.001]. In our study, quantitative T2 mapping in patients who were positive and negative for hs-TnI [51 (47.9, 52.8) and 48 (47, 49.4) ms] was significantly higher than the normal [42 (41, 45.2) ms] subjects (P < 0.001). CONCLUSION: In patients with early-stage COVID-19, myocardial oedema, and functional abnormalities are a frequent finding, while irreversible regional injury such as necrosis may be infrequent.

ABSTRACT

OBJECTIVE: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. METHODS: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( OR) and 95% confidence interval (95% CI) of the associations between comorbidities (cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19. RESULTS: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. CONCLUSION: Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

ABSTRACT

OBJECTIVE: Previous studies mainly reported the clinical characteristics of novel coronavirus 2019 (COVID-19) infections, but the research on clinical characteristics and treatment outcomes of COVID-19 patients with stroke is still rare. METHODS: A multi-center retrospective study was conducted at 11 hospitals in 4 provinces of China, and COVID-19 patients with stroke were enrolled from February 24 to May 4, 2020. We analyzed epidemiological, demographic, and clinical characteristics of cases as well as the laboratory test results, treatment regimens and outcomes, and the clinical characteristics and therapeutic outcomes were compared between severe and nonsevere patients, and by age group, respectively. RESULTS: A total of 27 patients [mean age: 66.41 (SD 12.1) years] were enrolled. Among them, 9 (33.3%) were severe patients and 18 (66.7%) were nonsevere patients; 17 (63.0%) were female; 19 (70.4%) were aged 60 years and above. The most common symptoms were fever [19 (70.4%)], fatigue [12 (44.4%)] and cough [11 (40.7%)], respectively. Abnormal laboratory findings of COVID-19 patients with stroke included high levels of C-reactive protein [19 (73.1%)], D-dimer [14 (58.3%)], blood glucose [14 (53.8%)], fibrinogen [13 (50.0%)], and decreased lymphocytes [12 (44.4%)]. Comparing to nonsevere cases with stroke, severe patients with stroke were likely to be older, susceptible to receiving oxygen inhalation, and had more complications (p < 0.05). In addition, there were significant differences in lymphocytes, neutrophils, lactate dehydrogenase, C-reactive protein, creatine kinase between the severe cases and nonsevere cases (p < 0.05). The older patients had a decreased platelet count and elevated fibrinogen, compared with the younger (p < 0.05). All patients (100%) received antiviral treatment, 12 (44.4%) received antibiotics treatment, 26 (96.3%) received Traditional Chinese Medicine (Lung cleansing & detoxifying decoction), and oxygen inhalation was in 18 (66.7%). The median duration of hospitalization was 16 days. By May 4, 2020, a total of 26 (96.3%) patients were cured and discharged, and 1 (3.7%) patients died. CONCLUSION: COVID-19 patients with stroke had poor indicators of coagulation system, and severe and older patients might have a higher risk of complications and unfavorable coagulation system. However, the overall treatment outcome is favorable.

ABSTRACT

Qingfei Paidu Decoction is a traditional Chinese medicine compound recommended by National Health Commission of the People's Republic of China and National Administration of Traditional Chinese Medicine for clinical therapies of coronavirus disease 2019(COVID-19). Qingfei Paidu Decoction consists of 21 traditional Chinese medicines, such as Asari Radix et Rhizoma. However, the dosage of Asari Radix et Rhizoma has been questioned by some people, because of one ancient proverb. To explore the rationality of the dosage of Asari Radix et Rhizoma in Qingfei Paidu Decoction, this study systematically examined the ancient and modern physicians' understanding of the toxicity of Asari Radix et Rhizoma, and collated the application and dosage of Asari Radix et Rhizoma in ancient prescriptions and modern clinics based on literature analysis. As a result, we found that ancient and modern physicians have different understanding on the toxicity of Asari Radix et Rhizoma and that the theory about the dosage of Asari Radix et Rhizoma is flawed. We also found that the dose of Asari Radix et Rhizoma in ancient and modern clinical applications was not constrained by ancient experience. Physicians usually increase the dosage of Asari Radix et Rhizoma in clinical therapy according to the actual conditions, and there were no adverse reactions. Additionally, according to laws and regulations concerning medical affairs, physician could increase or decrease the dosage of the drug under special circumstances. Based on the analysis of safety and effectiveness of Asari Radix et Rhizoma in Qingfei Paidu Decoction, we conclude that the dose of Asari Radix et Rhizoma in Qingfei Paidu Decoction is safe, effective and reasonable.

ABSTRACT

Coronavirus disease 2019(COVID-19) triggered a severe and complicated epidemic situation, and it is of great significance to discuss the rules and characteristics of the prescription of COVID-19 in traditional Chinese medicine. This study collected prevention and treatment approaches of traditional Chinese medicine for COVID-19 released from the National Health Committee of China, 7 provinces and municipal health committees, the Chinese Medicine Administration and Handbook of Traditional Chinese Medicine Diagnosis and Treatment of COVID-19 between January 1 and February 18, 2020, and prescriptions prepared by 3 masters of Chinese medicine and 4 well-known Chinese medicine experts. These information were selected according to the inclusion and exclusion criteria, and EpiData 3.0 software was used to establish the "Traditional Chinese Medicine Prescription Library for the Prevention and Treatment of COVID-19" and the "Common Database of Traditional Chinese Medicine for the Prevention and Treatment of COVID-19". A total of 93 effective Chinese medicine prescriptions and a total of 157 kinds of constituent medicines were collected. Data analysis was performed by SPSS 18.0 software. The results showed that: ①most of the medicines are with cold and warm properties, 69 with cold medicines, accounting for 43.95%, 57 with warm medicines, accounting for 36.31%, and less with hot medicines, taking up 1.27%; ②there are many pungent, bitter and sweet medicines, and the distribution of medicinal flavors is different at different disease stage. The pungent medicines are mostly found in the early stage, the bitter drugs are the main flavor in the middle and severe stage, and the sweet medicines are mostly used in the recovery stage; ③the meridian of the drug is more concentrated at the lung, stomach, and heart, and most of drugs are into the lung meridian, accounting for 24.55%; these medicines are mostly into the lungs and stomach in the initial and middle stages, and into the heart and kidney in severe stages; ④oral drugs are mostly non-toxic, among which only 6 kinds are toxic, namely Armeniacae Semen Amarum, Dryopteridis Crassirhizomatis Rhizoma, Paridis Rhizoma, Pinelliae Rhizoma, Aconiti Lateralis Radix Praeparaia; ⑤most of the drugs have five types of functions: treating exterior syndromes, resolving dampness, clearing heat, replenishing deficiency, resolving phlegm, cough, and asthma. In the early stage, both drugs for treating exterior syndromes and heat clearing drugs were equally used, accounting for 18.81% each. In the middle stage, drugs resolving phlegm, cough, and asthma drugs are more often used, accounting for 29.61%. In the severe stage, heat clearing drugs are mostly used, accounting for 33.33%. During the recovery period, tonic deficiency drugs are used the most, accounting for 36.47%. The medical characteristics and efficacy of Chinese medicine in preventing and treating COVID-19 are closely related to the understanding of the etiology of Chinese medicine and the location and pathogenesis of the disease. Staged medication and local conditions need attention during the identification and treatment of COVID-19 clinical syndromes.
