ABSTRACT

Coronaviruses are a family of viruses that infect mammals and birds. Coronaviruses cause infections of the respiratory system in humans, which can be minor or fatal. A comparative transcriptomic analysis has been performed to establish essential profiles of the gene expression of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) linked to cystic fibrosis (CF). Transcriptomic studies have been carried out in relation to SARS-CoV-2 since a number of people have been diagnosed with CF. The recognition of differentially expressed genes demonstrated 8 concordant genes shared between the SARS-CoV-2 and CF. Extensive gene ontology analysis and the discovery of pathway enrichment demonstrated SARS-CoV-2 response to CF. The gene ontological terms and pathway enrichment mechanisms derived from this research may affect the production of successful drugs, especially for the people with the following disorder. Identification of TF-miRNA association network reveals the interconnection between TF genes and miRNAs, which may be effective to reveal the other influenced disease that occurs for SARS-CoV-2 to CF. The enrichment of pathways reveals SARS-CoV-2-associated CF mostly engaged with the type of innate immune system, Toll-like receptor signaling pathway, pantothenate and CoA biosynthesis, allograft rejection, graft-versus-host disease, intestinal immune network for IgA production, mineral absorption, autoimmune thyroid disease, legionellosis, viral myocarditis, inflammatory bowel disease (IBD), etc. The drug compound identification demonstrates that the drug targets of IMIQUIMOD and raloxifene are the most significant with the significant hub DEGs.

ABSTRACT

BACKGROUND: In Germany, the first case of coronavirus disease 2019 (COVID-19) was registered on 28 January 2020. By February 2021, the third wave of the pandemic began. So far, only few data are available on the SARS-CoV-2 prevalence and the clinical impact of an infection in patients with cystic fibrosis (CF). METHODS: From February 2020 until March 2021, we screened 156 CF patients for anti-SARS-CoV-2 IgG antibodies (serology) and the presence of SARS-CoV-2 in deep throat saliva or nasopharyngeal swabs (molecular testing). From patients with confirmed SARS-CoV-2 infection, we recorded symptoms and collected clinical data. RESULTS: In total, 13 patients (8.3%) were tested positive for SARS-CoV-2 infection, most of them during the second and the beginning third wave of the pandemic. Ten positive tested patients described symptoms linked to COVID-19. The most common symptom was cough followed by fatigue and headache. SARS-CoV-2 infection did not impair lung function. No positive tested patient needed to be hospitalized. CONCLUSIONS: SARS-CoV-2 infections in patients with CF are not as rare as initially anticipated, as frequent testing revealed. However, infected patients did not experience more severe clinical courses or worse clinical outcome. Our observation is in line with published reports indicating that individuals with CF are not at higher risk for severe COVID-19.

ABSTRACT

BACKGROUND: We have recently reported reduced physical activity (PA) in people with cystic fibrosis (pwCF) with and without lung transplantation (LTX) during a 6-week stringent lockdown in Switzerland. This follow-up study explores the impact of coronavirus-2019 disease (COVID-19) related pandemic restrictions on individuals' therapy regimens and health-related aspects in pwCF. METHODS: We conducted a cross-sectional web-based national survey in Spring 2021. The survey included questions on daily PA, airway clearance and inhalation therapy, questions on COVID-19-compatible symptoms, diagnostic tests and vaccination status, and enquired health-related aspects covering the pandemic period between March 2020 to April 2021. RESULTS: 193 individuals with CF (53% female; 25% LTX recipients) participated. Among pwCF, 10 reported COVID-19 (n = 2 LTX recipients), two subjects were hospitalized, no invasive ventilation required, no deaths. The clinical course was generally mild. Overall, 46% reported less PA during the pandemic, mostly due to closed fitness facilities (85%), lack of motivation (34%), and changes in daily structures (21%). In contrast, 32/193 (17%) pwCF were able to increase their PA levels: 12 (38%) and 11 (34%) reported undertaking home-based training and outdoor activities more frequently; 6 (19%) reported an increase in routine PA, and another 3 (9%) started new activities. Among pwCF without LTX, 5% and 4% reported to undertake less airway clearance and inhalation therapy, respectively. CONCLUSIONS: Our study reveals unfavorable consequences of COVID-19 pandemic restrictions on PA of pwCF with unknown long-term consequences for their overall physical fitness and lung health. Strategies to overcome this undesirable situation are needed; increased uptake of telehealth PA programs and virtual exercise classes to promote PA participation might be one promising approach along with vaccination of pwCF and their close contacts.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has accelerated the transition to telehealth, including the use of home spirometry in cystic fibrosis. Evaluating the accuracy and precision of longitudinal home spirometry is a requisite for telehealth-based research. This secondary analysis of a CF study (eICE) evaluates whether there are cross-sectional or longitudinal differences between home and clinic spirometry. METHODS: Participants age ≥14 years with ppFEV1>25 were recruited from 2011-2015, issued a home spirometer, and asked to complete spirometry efforts twice per week for one year. Clinic spirometry was collected at baseline and every three months. Cross-sectional differences between clinic spirometry and the closest home spirometry measurement were analyzed. Longitudinally, we apply 5 methods to analyze the precision of home spirometry, and differences between clinic vs. home data. RESULTS: Home spirometry is estimated to be 2.0 (95% CI: 0.3, 3.5) percentage points lower than clinic spirometry cross-sectionally. Longitudinally, the estimates of 12-month change in home spirometry varied by analysis method from -2.6 to -1.0 ppFEV1/ year, with precision markedly different. However, home spirometry change estimates were qualitatively similar to the clinic results: -3.0 ppFEV1/year (95% CI: -4.1, -1.9). CONCLUSIONS: To leverage the potential cost, feasibility and convenience of home spirometry, the differences with clinic spirometry must be acknowledged. Significantly lower ppFEV1 in home devices shows that direct comparison to clinic spirometers may induce a spurious change from baseline, and additional variability in home devices impacts statistical power. The effect of coaching, setting, and equipment must be understood to use and improve home spirometry in CF.

ABSTRACT

BACKGROUND: Cystic Fibrosis Related Diabetes (CFRD) is a frequent comorbidity of patients with Cystic Fibrosis (CF). A worsening of clinical conditions appears before CFRD. It has been demonstrated a decline in pulmonary function and nutritional status also in patients with prediabetes. Few trials show that insulin may be beneficial in prediabetic CF patients, to date guidelines do not recommend for this condition. CASE PRESENTATION: We report a case of a patient treated with insulin glargine at 13 years, due to glycemic intolerance, and with Lumacaftor/Ivacaftor at 15 years. A reduction of pulmonary exacerbations was observed after glargine therapy, also confirmed after the starting of Lumacaftor/ Ivacaftor in this patient. Pulmonary function improved only after the first year of glargine therapy, then a deterioration appeared due to the natural history of CF lung damage. During the COVID-19 lockdown, poor adherence to care contributed to diabetes mellitus onset needing high insulin requirements. After two weeks the patient returned to prediabetic condition and his previous dose of glargine. CONCLUSIONS: our case highlights firstly that insulin glargine has contributed to preserve him from further clinical worsening due to prediabetes in the years before pandemic, secondly the negative impact of COVID-19 lockdown on the clinical course of a chronic disease as CF.

ABSTRACT

Systemic pools of ATP are elevated in individuals homozygous for cystic fibrosis (CF) as evidenced by elevated blood and plasma ATP levels. This elevated ATP level seems to provide benefit in the presence of advanced solid tumors (Abraham et al., Nature Medicine 2(5):593-596, 1996). We published in this journal a paper showing that IV ATP can elevate the depleted ATP pools of advanced cancer patients up to levels found in CF patients with subsequent clinical, biochemical, and quality of life (QOL) improvements (Rapaport et al., Purinergic Signalling 11(2): 251-262, 2015). We hypothesize that the elevated ATP levels seen in CF patients may be benefiting CF patients in another way: by improving their survival after contracting COVID-19. We discuss here the reasoning behind this hypothesis and suggest how these findings might be applied clinically in the general population.

ABSTRACT

Background: Cystic fibrosis (CF) is a potentially mortal disease characterized by a chronic pulmonary disease with persistent airway infection. Children with this disease are more susceptible to respiratory infections due to the limitation in mucociliary transport and anatomical disruption of the bronchial tree. SARS-CoV-2 causes COVID-19, a respiratory illness related to exacerbations of chronic pulmonary pathologies in children, such as CF and asthma. There are not enough case reports on pediatric patients with SARS-CoV-2 infection and CF, for which we share our experience. Case report: A 22-month-old male patient diagnosed with CF presented in the hospital with cough, fever, and increased respiratory work. The patient received supplemental oxygen and antibiotic and antiviral therapy. Positive results for type B influenza and RT-PCR (reverse transcription-polymerase chain reaction) for SARS-CoV-2 were obtained. Due to the persistence of respiratory difficulty, high-flow therapy was initiated, with a good response. After an episode of hypoxemia, bradycardia, and increased respiratory work secondary to accumulated secretions, orotracheal intubation and invasive mechanical ventilation were performed. The patient evolved with clinical and gasometric improvement. After 10 days of in-hospital antibiotic management with adequate clinical evolution, the patient was discharged to complete oral treatment and home isolation. Conclusions: We present a case of chronic respiratory disease and SARS-CoV-2 infection with severity criteria in a pediatric patient. The evolution was favorable with timely support management and antibiotic therapy in a third-level hospital.


Introducción: La fibrosis quística es una afección potencialmente mortal caracterizada por enfermedad pulmonar crónica con infección persistente de las vías aéreas. Los niños con esta enfermedad son más susceptibles a infecciones respiratorias debido a la limitación en el transporte mucociliar y la distorsión anatómica del árbol bronquial. El SARS-CoV-2 (coronavirus tipo 2 del síndrome agudo respiratorio grave) es el virus causante de la COVID-19, enfermedad respiratoria que puede estar relacionada con exacerbaciones de patologías pulmonares crónicas en niños, como la fibrosis quística y el asma. No hay suficientes reportes de casos de pacientes pediátricos con infección por SARS-CoV-2 y fibrosis quística, por lo cual se comparte la presente experiencia. Caso clínico: Paciente de sexo masculino de 22 meses de edad con diagnóstico de fibrosis quística que presentó tos, fiebre y aumento en el trabajo respiratorio. A su ingreso se inició manejo con oxígeno suplementario y tratamiento antibiótico y antiviral. Se obtuvo prueba positiva para influenza tipo B y para SARS-CoV-2 por RT-PCR (reacción en cadena de la polimerasa de transcriptasa inversa). Ante un episodio de hipoxemia, bradicardia y mayor trabajo respiratorio, requirió intubación orotraqueal y ventilación mecánica invasiva. El paciente evolucionó con mejoría clínica y gasométrica. Después de 10 días de manejo antibiótico intrahospitalario, con adecuada evolución clínica, egresó para completar tratamiento por vía oral y aislamiento en casa. Conclusiones: Se presenta el caso de un paciente pediátrico con enfermedad respiratoria crónica de base e infección por SARS-CoV-2 con criterios de gravedad. El paciente evolucionó favorablemente con el manejo de soporte oportuno y terapia de antibióticos en un hospital de tercer nivel.

ABSTRACT

We report the case of a man affected by cystic fibrosis who developed a severe SARS-CoV-2 related pneumonia in March 2020. In addition to lopinavir/ritonavir and hydroxychloroquine, he was treated with two doses of tocilizumab, displaying a significant clinical improvement. This is the first case described in the literature of an adult patient affected by cystic fibrosis who received tocilizumab for COVID-19, with documented total recovery, also assessed by a spirometry.

ABSTRACT

Cystic fibrosis (CF) is an autosomal recessive disease which involves the mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. CF involves in the inflammatory processes and is considered as a multisystem disorder that is not confined to lungs, but it also affects other vital organs that leads to numerous co-morbidities. The respiratory disorder in the CF results in mortality and morbidity which is characterized by series of serious events involving mucus hypersecretion, microbial infections, airways obstruction, inflammation, destruction of epithelium, tissue remodeling and terminal lung diseases. Mucins are the high molecular weight glycoproteins important for the viscoelastic properties of the mucus, play a significant role in the disease mechanisms. Determining the functional association between the CFTR and mucins might help to identify the putative target for specific therapeutic approach. In fact, furin enzyme which helps in the entry of novel COVID-19 virus into the cell, is upregulated in CF and this can also serve as a potential target for CF treatment. Moreover, the use of nano-formulations for CF treatment is an area of research being widely studied as they have also demonstrated promising outcomes. The in-depth knowledge of non-coding RNAs like miRNAs and lncRNAs and their functional association with CFTR gene expression and mutation can provide a different range of opportunity to identify the promising therapeutic approaches for CF.

ABSTRACT

BACKGROUND: We aim to assess the anxiety and depressive symptoms related to the COVID-19 pandemic in children with chronic lung disease and their parents and also to evaluate parents' coping strategies. METHODS: Parents of children aged 4-18 years, with chronic lung disease (study group n = 113) and healthy control (n = 108) were enrolled in the study. General Health Questionnaire-12, specific COVID-19 related anxiety questions, The Coping Orientation to Problems Experienced inventory, coronavirus-related psychiatric symptom scale in children-parental form were used to analyze the psychiatric effects of COVID-19. Parents were also asked about how online education affected their family life and children. All data were compared between children/parents in the study and control groups. Risk factors related with anxiety scores of children were also analyzed. RESULTS: Talking about the pandemic, concern about coronavirus transmission, taking precaution to prevent coronavirus transmission, making pressure to protect from COVID-19 were significantly higher in parents within the study group (p < .05). Parents in the study group used more problem-focused coping than parents in the control group (p = .003). Anxiety symptoms score was higher in children of the study group (p = .007). Parents in the study group found online education more useful than parents in the control group. CONCLUSION: Children with chronic lung diseases and their parents have more anxiety due to COVID-19 pandemic and these parents use more mature coping strategies to manage the stress of the pandemic. Longitudinal and larger studies should be done in all aspects of online education in children with chronic lung diseases.

ABSTRACT

BACKGROUND: Severe acute respiratory syndrome - coronavirus-2 (SARS-CoV-2) has caused a pandemic threatening the life of people with chronic respiratory diseases including cystic fibrosis (CF). This study was designed to investigate health-related aspects of individuals with CF, with and without lung transplantation (LTX), their communication with their specialist healthcare providers during the pandemic, potential changes in peoples' individual therapy regimes and daily physical activity levels. METHODS: A web-based survey was conducted among Swiss adults with CF with and without LTX, study period from March 16th, 2020 - the day the "extraordinary situation" was officially declared in Switzerland introducing stringent measures protecting the public - until May 16th, 2020. RESULTS: 327 individuals (25% LTX recipients) were included, 45 individuals reported coronavirus-2019 disease (COVID-19) like symptoms. Of 28 subjects tested, only three subjects were tested positive, all with mild symptoms, no hospitalization required. Almost half of the survey respondents (45%) reported undertaking less physical activity during the lockdown, while 79% and 91% of participants reported no change in traditional airway clearance and inhalation therapies, respectively. Distress regarding a potential SARS-CoV-2 infection or worsening of lung disease were no major concerns for subjects. CONCLUSIONS: Our study reveals that the direct impact of SARS-CoV-2 on clinical outcomes of individuals with CF was mild although people with chronic lung diseases like CF are considered a high-risk population; overall, this is reassuring. However, strict lockdown measures substantially affected peoples' physical activity levels, a vital cornerstone of CF therapy; and this is worrisome.
