Varicella zoster virus reactivation following COVID-19 vaccination in patients with autoimmune inflammatory rheumatic diseases: A cross-sectional Chinese study of 318 cases.

Recently, varicella-zoster virus (VZV) reactivation has been observed after the administration of coronavirus disease 2019 (COVID-19) vaccines. Autoimmune inflammatory rheumatic diseases (AIIRDs) patients are at a higher risk for VZV reactivation for immunocompromised status. The study aimed to investigate the adverse events (AEs), especially VZV reactivation, following vaccination against  severe acute respiratory syndrome coronavirus-2 in a Chinese cohort of AIIRD patients. A cross-sectional survey using an online questionnaire was conducted among AIIRD patients and healthy controls (HCs). Multivariate logistic regression was used to identify potential factors associated with VZV reactivation. 318 AIIRD patients and 318 age and sex-matched HCs who got COVID-19 inactivated vaccines were recruited. The main AIIRDs are rheumatoid arthritis (31.8%) and systemic lupus erythematous (23.9%). Most of patients (85.5%) had stable disease and 13.2% of them had aggravation after vaccination. Compared to HCs, patients had higher rates of rash (p = 0.001), arthralgia (p < 0.001) and insomnia (p = 0.007). In addition, there were 6 (1.9%) AIIRD patients and 5 (1.6%) HCs reported VZV reactivation after the COVID-19 vaccination (p = 0.761). Multivariate logistic regression analysis illustrated that diabetes mellitus (odd ratio [OR], 20.69; 95% confidence interval [CI], 1.08-396.79; p = 0.044), chronic hepatitis B virus infection (OR, 24.34; 95% CI, 1.27-466.74; p = 0.034), and mycophenolate mofetil (OR, 40.61; 95% CI, 3.33-496.15; p = 0.004) independently identified patients with VZV reactivation. Our findings showed that the inactivated COVID-19 vaccination was safe for AIIRD patients though some patients could suffer from VZV reactivation.

Efficacy and safety of glycyrrhizic acid preparation treating comorbid liver injury in COVID-19: A systematic review.

Background: No specific drug for COVID-19 has been found, and many studies have found that different degrees of liver injury often occurred after infection with COVID-19. Glycyrrhizic acid preparation (GAP) has been frequently used clinically, often combined with conventional treatments such as antiviral therapy, to improve the prognosis of COVID-19 and patients' liver function. Aims: To critically review and analyze clinical evidence on the efficacy and safety of GAP in the treatment of COVID-19 alone and COVID-19 with comorbid liver injury. Methods: A systematic literature review was performed following a sensitive searching strategy that examines all articles published in "WHO COVID-19 Research Database," "Cochrane Library," "VIP," "CNKI," "Wanfang," and "CBM" from 2020 to July 2022. Articles were evaluated by peer reviewers and used Joanna Briggs Institute (JBI) critical appraisal tools to complete the assessment of the risk of bias. Results: Ten clinical studies were finally included, involving 598 patients with COVID-19, of whom 189 were confirmed to be with comorbid liver injury. The main GAPs used are diammonium glycyrrhizinate and magnesium isoglycyrrhizinate, which have shown efficacy in improving liver function, inhibiting inflammation, and enhancing immunity. We are still seeking more related research. Conclusion: Glycyrrhizic acid preparations (mainly diammonium glycyrrhizinate and magnesium isoglycyrrhizinate) have a considerable clinical effect on improving liver function in patients with COVID-19 alone or with comorbid liver injury. Further studies on the use of GAP in the treatment of COVID-19 with comorbid liver injury and its mechanism are still needed.

Comparison of the respiratory tract microbiome in hospitalized COVID-19 patients with different disease severity.

Little is known about the characteristics of respiratory tract microbiome in Coronavirus disease 2019 (COVID-19) inpatients with different severity. We conducted a study that expected to clarify these characteristics as much as possible. A cross-sectional study was conducted to characterize respiratory tract microbial communities of 69 COVID-19 inpatients from 64 nasopharyngeal swabs and 5 sputum specimens using 16S ribosomal RNA gene V3-V4 region sequencing. The bacterial profiles were analyzed to find potential biomarkers by the two-step method, the combination of random forest model and the linear discriminant analysis effect size, and explore the connections with clinical characteristics by Spearman's rank test. Compared with mild COVID-19 patients, severe patients had significantly decreased bacterial diversity (p-values were less than 0.05 in the alpha and beta diversity) and relative lower abundance of opportunistic pathogens, including Actinomyces, Prevotella, Rothia, Streptococcus, Veillonella. Eight potential biomarkers including Treponema, Leptotrichia, Lachnoanaerobaculum, Parvimonas, Alloprevotella, Porphyromonas, Gemella, and Streptococcus were found to distinguish the mild COVID-19 patients from the severe COVID-19 patients. The genera of Actinomyces and Prevotella were negatively correlated with age in two groups. Intensive care unit admission, neutrophil count, and lymphocyte count were significantly correlated with different genera in the two groups. In addition, there was a positive correlation between Klebsiella and white blood cell count in two groups. The respiratory tract microbiome had significant differences in COVID-19 patients with different severity. The value of the respiratory tract microbiome as predictive biomarkers for COVID-19 severity deserves further exploration.

The COVID‐19 vaccine: Attitudes and vaccination in patients with autoimmune inflammatory rheumatic diseases

Background We examined attitudes toward the COVID‐19 vaccine, potential factors underlying these attitudes, and ways to increase vaccination willingness in autoimmune inflammatory rheumatic diseases (AIIRD) patients. Methods A multicenter, web‐based, observational survey using an online questionnaire was conducted among AIIRD patients aged ≥18 years from May 24, 2021, to June 3, 2021. Participants were 3104 AIIRD patients (2921 unvaccinated and 183 vaccinated). Results Of the unvaccinated patients, 32.9% were willing to receive the COVID‐19 vaccine, 45.0% were uncertain, and 14.8% were unwilling. When vaccination was recommended by physicians, patients' willingness increased to 93.8%. Participants' main concerns were that the vaccine may aggravate AIIRD disease (63.0%) and may cause vaccine‐related adverse events (19.9%). Female patients were less likely to be vaccinated. However, patients who had children aged ≤18 years were more willing to be vaccinated. In addition, vaccination willingness was higher in patients with trust in the safety and efficacy of the COVID‐19 vaccine. Notably, 183 (5.9%) patients were vaccinated. The major vaccination side effects were injection reaction, myalgia, and fatigue. At a median follow‐up of 88 (38, 131) days, patients' disease activities were stable. Conclusions The findings show that AIIRD patients were unwilling to receive the COVID‐19 vaccine because of fears of potential disease exacerbation and additional adverse events. Sociodemographic characteristics and concerns about COVID‐19 disease and vaccines had a significant effect on vaccination willingness. Key points The percentage of patients willing to receive the COVID‐19 vaccine greatly increased when vaccination was recommended by a physician. Gender, marital status, age of the patients' children, smoking, trust in the safety and efficacy of the vaccine, and previous vaccinations had significant effects on the willingness of patients with AIIRDs to receive the COVID‐19 vaccine. The data from vaccinated patients indicated no aggravation of AIIRD or additional adverse events. The population characteristics of AIIRD patients with different attitudes towards COVID‐19 vaccine.

Pediatric asthma control during the COVID-19 pandemic: A systematic review and meta-analysis.

BACKGROUND: With the onset of the coronavirus disease 2019 (COVID-19) pandemic, many experts expected that asthma-associated morbidity because of severe acute respiratory syndrome coronavirus 2 infection would dramatically increase. However, some studies suggested that there was no apparent increasing in asthma-related morbidity in children with asthma, it is even possible children may have improved outcomes. To understand the relationship between the COVID-19 pandemic and asthma outcomes, we performed this article. METHODS: We searched PubMed, Embase, and Cochrane Library to find literature from December 2019 to June 2021 related to COVID-19 and children's asthma control, among which results such as abstracts, comments, letters, reviews, and case reports were excluded. The level of asthma control during the COVID-19 pandemic was synthesized and discussed by outcomes of asthma exacerbation, emergency room visit, asthma admission, and childhood asthma control test (c-ACT). RESULTS: A total of 22,159 subjects were included in 10 studies. Random effect model was used to account for the data. Compared with the same period before the COVID-19 pandemic, asthma exacerbation reduced (odds ratio [OR] = 0.26, 95% confidence interval [CI] = [0.14-0.48], Z = 4.32, p < 0.0001), the odds of emergency room visit decreased as well (OR = 0.11, 95% CI = [0.04-0.26], Z = 4.98, p < 0.00001). The outcome of asthma admission showed no significant difference (OR = 0.84, 95% CI = [0.32-2.20], Z = 0.36, p = 0.72). The outcome of c-ACT scores were not analyzed because of the different manifestations used. Overall, c-ACT scores reduced during the pandemic. CONCLUSION: Compared to the same period before the COVID-19 pandemic, the level of asthma control has been significantly improved. We need to understand the exact factors leading to these improvements and find methods to sustain it.

Experience of comprehensive interventions in reducing occupational exposure to COVID-19.

IMPORTANCE: The infection of medical personnel with COVID-19 was a disaster for both patients and doctors. However, some effective measures can prevent medical staff from becoming infected. This article introduces those measures and thus provides a reference for other hospitals. OBJECTIVE: In order to reduce the risk of occupational exposure and of the infection of medical staff, this article analyzed the factors, causes and experience of medical personnel on their occupational exposure to COVID-19. Some effective and targeted intervention measures can be implemented in order to avoid the occupational exposure of medical staff to COVID-19. EVIDENCE REVIEW: In this single-center case series involving 196 medical personnel, occupational exposure to COVID-19 was present. Nursing staff accounted for 67.35% of those cases. The relationships with an exposure source were found to be as follows: doctors and patients (87.24%), colleagues (10.20%), and roommates (2.55%). Occupational exposure was found to be present in the clinical department, radiology department, central sterile supply department, as well as in the outpatient clinics and operating rooms. The non-surgical departments accounted for 72.96% and direct contact accounted for 84.69% while failure to wear surgical masks (84.18%) and operating on the patient without wearing goggles/face shield (8.16%) were the main causes of occupational exposure. The occurrence of occupational exposure to COVID-19 declined to 0.19% after an extensive and comprehensive intervention program. CONCLUSIONS AND RELEVANCE: Some effective measures such as hand hygiene, wearing surgical masks in and around the hospital, reasonable use of goggles/face screens, raising awareness of protective measures, minimizing the number of elective operations, strengthening training as well as many other control measures were instrumental in reducing occupational exposure. For any medical institution there is room for improvement in terms of personal protection to reduce occupational exposure.
