Fewer Bronchiectasis Exacerbations During the "Lockdown" for COVID-19: Can We Convert Knowledge into Action?

Increased exacerbations of bronchiectasis following recovery from mild COVID-19 in patients with non-cystic fibrosis bronchiectasis

BACKGROUND AND OBJECTIVE

Respiratory viral infection is a common trigger of bronchiectasis exacerbation. Knowledge of the intermediate to long-term effect of COVID-19 on bronchiectasis is poor.

METHODS

A retrospective cohort study of patient records was conducted to assess the frequency of bronchiectasis exacerbation following recovery from mild-to-moderate COVID-19. The exacerbation frequency at baseline, using 2019 and 2019-2021 data, was compared with that during the 1 year following recovery.

RESULTS

A total of 234 adult patient records who had a confirmed diagnosis of bronchiectasis were identified, of whom 52 (22.2%) were classified as the COVID-19 group. Patients with COVID-19 had significantly more frequent annual exacerbations of bronchiectasis (total exacerbations and hospitalizations). Compared with 2019-2021 data, the total exacerbation frequency decreased by 0.1 ± 0.51 per year among non-COVID-19 patients but increased by 0.68 ± 1.09 per year among the COVID-19 group (p < 0.001). Compared with 2019 only data, exacerbation frequency decreased by 0.14 ± 0.79 per year among non-COVID-19 patients but increased by 0.76 ± 1.17 per year in the COVID-19 group, p < 0.001. The annual frequency of hospitalization for bronchiectasis increased by 0.01 ± 0.32 per year among non-COVID-19 patients and increased by 0.39 ± 1.06 per year in the COVID-19 group (p < 0.001) compared with 2019 to 2021 data. When compared with only 2019 data, it remained unchanged at 0 ± 0.43 per year among non-COVID-19 patients but increased to 0.38 ± 1.12 per year among COVID-19 patients (p < 0.001).

CONCLUSION

Mild-to-moderate COVID-19 was associated with an increase in frequency of bronchiectasis exacerbation and frequency of hospitalizations following recovery.

Symptoms and medical resource utilization of patients with bronchiectasis after SARS-CoV-2 infection

Background

The impact of COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on patients with bronchiectasis in terms of symptoms, self-management and medical resource utilization was unknown.

Objective

To describe the impact of infection by SARS-CoV-2 on fluctuation of symptoms, self-management and medical resource utilization of patients with bronchiectasis during the pandemic of COVID-19.

Methods

This was a single-center cross-sectional questionnaire study performed in Peking University Third Hospital. An online questionnaire investigation addressing the impact of SARS-CoV-2 infection on respiratory symptoms, self-management and medical resource utilization was conducted among patients with bronchiectasis during the COVID-19 surge in December 2022 in Beijing, China.

Results

Five hundred patients with bronchiectasis, with 285 (57%) females, and a mean (± S D ) age of 57.9 ± 15.1 years, completed the telephone questionnaire. The reported prevalence of COVID-19 was 81.2% (406/500). Of the 406 COVID-19 patients, 89.2% experienced fever lasting mostly for no more than 3 days, 70.6 and 61.8% reported exacerbated cough and sputum production respectively, and 17.7% reported worsened dyspnea. Notable 37.4% of the patients with COVID-19 experienced symptoms consistent with the definition of an acute exacerbation of bronchiectasis. However, 76.6% (311/406) of the infected patients did not seek medical care but managed at home. Of the patients who visited hospitals, 26.3% (25/95) needed hospitalization and 2.1% (2/95) needed ICU admission. Multi-factors logistic regression analysis showed that younger age (p = 0.012) and not using a bronchodilator agent(p = 0.022) were independently associated with SARS-CoV-2 infection, while a history of exacerbation of bronchiectasis in the past year (p = 0.006) and daily use of expectorants (p = 0.002) were associated with emergency visit and/or hospitalization for patients with bronchiectasis after SARS-CoV-2 infection.

Conclusion

During the COVID-19 surge, the infection rate of SARS-CoV-2 in patients with bronchiectasis was high, and most of the patients experienced new-onset or exacerbated respiratory symptoms, but only a minority needed medical visits. Our survey results further underscore the importance of patients' disease awareness and self-management skills during a pandemic like COVID-19.

Treatment adherence and anxiety levels of bronchiectasis patients in the COVID-19 pandemic

It has been reported that during the coronavirus disease-2019 (COVID-19) pandemic, bronchiectasis patients were adversely affected due to their limited respiratory functions and acute exacerbations which were triggered by viral infections. The increased concern in the population during the pandemic has affected the attitudes of people toward avoiding disease and patients' treatment compliance. It is unclear whether treatment adherence and anxiety levels of bronchiectasis patients have changed during the pandemic. We aimed to evaluate treatment adherence and anxiety levels in patients with bronchiectasis. A cross-sectional survey was conducted between May and November 2021. A total of 123 patients with bronchiectasis and 110 adults without chronic diseases were included in the control group. Patient demographic information, bronchiectasis follow-up data, and COVID-19 history were recorded. Then, patients filled out "MARS-5 Index" (Medical Adherence Report Scale-5), Beck Anxiety Scale and the Effect of Events Scale (IES-R). Responses of questionnaires were statistically analyzed. Our results showed that the majority of patients with bronchiectasis had high Medical Adherence Report Scale-5 index total scores during the COVID-19 pandemic (86.2%). The total scores on the Beck Anxiety Scale of bronchiectasis patients who did not have COVID-19 were significantly higher than those who had COVID-19 (P = .04). The total scores on the IES-R were found to be significantly higher in the control group (P < .001). No significant difference was found in the total scores on the Beck Anxiety Scale between the patients and the control group. The bronchiectasis patients had high adherence to their current treatment during the COVID-19 period and were less affected by the pandemic and its psychological effects compared to the healthy population. Furthermore, individuals diagnosed with bronchiectasis who were not infected with COVID-19 demonstrated increased levels of anxiety compared to those who were infected with COVID-19 which may be due to their concern about contracting the disease.

Short and Long-Term Impact of COVID-19 Infection on Previous Respiratory Diseases

On March 11, 2020, the World Health Organization declared Coronavirus Disease 2019 (COVID-19) a pandemic. Till now, it affected 452.4 million (Spain, 11.18 million) persons all over the world with a total of 6.04 million of deaths (Spain, 100,992). It is observed that 75% of hospitalized COVID-19 patients have at least one COVID-19 associated comorbidity. It was shown that people with underlying chronic illnesses are more likely to get it and grow seriously ill. Individuals with COVID-19 who have a past medical history of cardiovascular disorder, cancer, obesity, chronic lung disease, diabetes, or neurological disease had the worst prognosis and are more likely to develop acute respiratory distress syndrome or pneumonia. COVID-19 can affect the respiratory system in a variety of ways and across a spectrum of levels of disease severity, depending on a person's immune system, age and comorbidities. Symptoms can range from mild, such as cough, shortness of breath and fever, to critical disease, including respiratory failure, shock and multi-organ system failure. So, COVID-19 infection can cause overall worsening of these previous respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, etc. This review aims to provide information on the impact of the COVID-19 disease on pre-existing lung comorbidities.

Chronic respiratory diseases other than asthma in children: the COVID-19 tsunami

Coronavirus disease 2019 (COVID-19) affects all components of the respiratory system, including the neuromuscular breathing apparatus, conducting and respiratory airways, pulmonary vascular endothelium, and pulmonary blood flow. In contrast to other respiratory viruses, children have less severe symptoms when infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A minority of children experience a post-infectious inflammatory syndrome, the pathology and long-term outcomes of which are poorly understood. The reason for the lower burden of symptomatic disease in children is not yet clear, but several pathophysiological characteristics are postulated. The SARS-CoV-2 pandemic has brought distinct challenges to the care of children globally. Proper recommendations have been proposed for a range of non-asthmatic respiratory disorders in children, including primary ciliary dyskinesia and cystic fibrosis. These recommendations involve the continuation of the treatment during this period and ways to maintain stability. School closures, loss of follow-up visit attendance, and loss of other protective systems for children are the indirect outcomes of measures to mitigate the COVID-19 pandemic. Moreover, COVID-19 has reshaped the delivery of respiratory care in children, with non-urgent and elective procedures being postponed, and distancing imperatives have led to rapid scaling of telemedicine. The pandemic has seen an unprecedented reorientation in clinical trial research towards COVID-19 and a disruption in other trials worldwide, which will have long-lasting effects on medical science. In this narrative review, we sought to outline the most recent findings on the direct and indirect effects of SARS-CoV-2 pandemic on pediatric respiratory chronic diseases other than asthma, by critically revising the most recent literature on the subject.

Exacerbation of bronchiectasis by Pseudomonas putida complicating COVID-19 disease: A case report

Novel coronavirus infection presents with greater severity in individuals with comorbid chronic lung diseases. Bronchiectasis is an illness characterized by permanent enlargement of the airways, presenting with chronic cough and sputum production and vulnerability to lung infections. Bronchiectasis is not a common comorbid disease in patients with COVID-19 disease and bronchiectasis exacerbation rates were decreased during the pandemic. However, COVID-19 disease is associated with worse outcomes in patients with bronchiectasis and patients with bronchiectasis are more susceptible to SARS-CoV-2 infection development. Pseudomonas putida is an opportunistic pathogen, causing infections mostly in immunocompromised hosts and is not a frequent bacterial colonizer in patients with bronchiectasis. This present study reports a rare case of exacerbation of bronchiectasis by Pseudomonas putida complicating COVID-19 disease in an immunocompetent 70-year-old woman. Clinicians should be aware that SARS-CoV-2 infection is probably a precipitating factor of bronchiectasis exacerbation while bronchiectasis is a risk factor for greater severity of SARS-CoV-2 infection.
