Immunology of COVID‐19: mechanisms, clinical outcome, diagnostics and perspectives – a report of the European Academy of Allergy and Clinical Immunology (EAACI)

"We also summarize known and potential SARS‐CoV‐2 receptors on epithelial barriers, immune cells, endothelium and clinically involved organs such as lung, gut, kidney, cardiovascular and neuronal system. Finally, we discuss the known and potential mechanisms underlying the involvement of comorbidities, gender and age in development of COVID‐19. Consequently, we highlight the knowledge gaps and urgent research requirements to provide a quick roadmap for ongoing and needed COVID‐19 studies."

Telemedicine allows quantitative measuring of olfactory dysfunction in COVID‐19

"For the first time, quantitative psychophysical analyses of olfaction were performed over a full course of COVID-19 in this homogenous cohort of relatively young adults, while previous studies used self-ratings, only. It is well accepted that self-ratings largely underestimate olfactory dysfunction. Usually required face-to-face contact seems to cause this systematic error, while telemedicine consultations allows safe testing for patients and staff. The comprehensive impairment without nasal symptoms supports the suggestion of a neurotropic and neuro-invasive virus that is site-specific for the olfactory system using angiotensin-converting-enzyme-receptor-2 (ACE2) for intracellular invasion."

The role of peripheral blood eosinophil counts in COVID‐19 patients

"The majority of COVID‐19 patients (71.7%) had a decrease in circulating EOS counts, which was significantly more frequent than other types of pneumonia patients. EOS counts had good value for COVID‐19 prediction, even higher when combined with NLR. Patients with low EOS counts at admission were more likely to have fever, fatigue and shortness of breath, with more lesions in chest CT and radiographic aggravation, longer length of hospital stay and course of disease than those with normal EOS counts."

Eosinopenia is associated with greater severity in patients with coronavirus disease 2019

"Based on accumulating data, patients with severe COVID-19 show a trend towards eosinopenia, which raises the concern whether eosinopenia is associated with the disease severity. Eosinophil, initially identified as a key effector cell of allergy, has now been demonstrated to possess antiviral capacities and serve to amply immune response and thus dampen inflammation. It is currently not known whether COVID-19 patients with eosinopenia are also more likely to develop into critically illness. This updated analysis aimed to investigate the association between eosinopenia and COVID-19 severity."

COVID‐19 in a patient with severe asthma treated with Omalizumab

"ircumstantial evidence suggests that patients with allergic asthma might have a lower risk to develop severe forms of COVID‐19. In addition, the anti‐IgE antibody Omalizumab was shown to enhance anti‐viral immunity. We report a case of a 52‐year‐old man with severe allergic asthma treated with Omalizumab with no evidence of an asthma exacerbation, loss of asthma control or pneumonia during symptomatic COVID‐19 disease. We hypothesize that the underlying disease (allergic asthma) or the antibody used for treatment (Omalizumab), or both, might have exerted protective effects."

Clinical characteristics of 182 pediatric COVID‐19 patients with different severities and allergic status

"Pediatric COVID‐19 patients tended to have a mild clinical course. Patients with pneumonia had higher proportion of fever and cough and increased inflammatory biomarkers than those without pneumonia. There was no difference between allergic and non‐allergic COVID‐19 children in disease incidence, clinical features, laboratory and immunological findings. Allergy was not a risk factor for developing and severity of SARS‐CoV‐2 infection and hardly influenced the disease course of COVID‐19 in children."

Clinical characteristics of COVID‐19 patients combined with allergy

"(...) we found that combined allergies might reduce the destructive power of SARS-CoV-2 infection. COVID-19 patients combined with allergy had less severe initial conditions and a lower degree of lung lesions, which might owe to the fact that T lymphocytes were less damaged by SARSCOV2. Other underlying diseases may also exist with these patients and often with the worse condition and worse prognosis."

Considerations on Biologicals for Patients with allergic disease in times of the COVID‐19 pandemic: an EAACI Statement

"Currently, there is very little evidence for an enhanced risk of patients with allergic diseases to develop severe COVID‐19 with studies focusing on severe allergic phenotypes lacking. At present, non‐infected patients on biologicals for the treatment of asthma, atopic dermatitis, chronic rhinosinusitis with nasal polyps or chronic spontaneous urticaria should continue their biologicals targeting type 2 inflammation via self‐application. In case of an active SARS‐CoV‐2 infection, biological treatment needs to be stopped until clinical recovery and SARS‐CoV‐2 negativity is established and treatment with biologicals should be re‐initiated. Maintenance of add‐on therapy and a constant assessment of disease control, apart from acute management is demanded."

Distribution of ACE2, CD147, CD26 and other SARS‐CoV‐2 associated molecules in tissues and immune cells in health and in asthma, COPD, obesity, hypertension, and COVID‐19 risk factors

"Our data suggest different receptor repertoire potentially involved in the SARS-CoV-2 infection at the epithelial barriers and in the immune cells. Altered expression of these receptors related with age, gender, obesity and smoking, as well as with the disease status might contribute to COVID-19 morbidity and severity patterns."

Is asthma protective against COVID‐19?

"(...) there are no published reports of other type 2 conditions associated with severe COVID-19. Herein, we share some clues supporting the hypothesis that type 2 conditions do not represent a risk factor, despite the most morbidity occurring due to SARS-CoV-2 induced lung damage."

Low prevalence of bronchial asthma and chronic obstructive lung disease among intensive care unit patients with COVID‐19

"In an uncontrolled study, we could not rule out the contribution of COPD to the more severe outcomes of SARS-CoV-2 infection that was shown in the previous studies. However, patients with bronchial asthma do not seem to be at increased risk of SARS-CoV-2 induced ARDS. Our findings suggest that there is no need to change standard treatment for chronic respiratory diseases during pandemic of COVID-19. Additional studies are needed to prove this hypothesis."

COVID‐19 Clinical trials: quality matters more than quantity

"Hopefully, the efforts of clinical researchers in the fight against the SARS Cov‐2 will result into the identification of effective treatments. To make this possible, clinical research should be oriented by guidelines for more harmonized high‐quality studies and by a united commitment of the scientific community to share personal knowledge and data. Allergists and clinical immunologists should have a leading role in this unprecedent challenge."

"Coronavirus disease 2019 (COVID‐19) pandemic is affecting people at any age with a more severe course in patients with chronic diseases or comorbidities, males and elderly patients. The Center for Disease Control and Prevention (CDC) initially proposed that patients with chronic lung diseases, including moderate‐severe asthma, and allergy may have a higher risk of developing severe COVID‐19 than otherwise healthy people"

Managing ocular allergy in the time of COVID‐19

"This spring, the majority of allergic patients are confined to their homes due to COVID‐19 pandemic restrictions. In the following weeks, these restrictions will be reduced andpeople will be allowed to take walks, go jogging, and return to work.Spring is the time for ocular allergy (OA) to emerge with signs and symptoms consequent to increasing pollen counts. Even when wearing a mask, the eyes may remain unprotectedleading to an increase in ocular symptoms and patients seeking treatment forOA. However, access to routine consultation may remain problematic for many patients."

Asthma and COVID‐19: is asthma a risk factor for severe outcomes?

"My recommendations to people with asthma and those treating them are most importantly to optimize asthma control with standard therapies, but if asthma control is not optimal despite appropriate use of standard therapies, to have a low threshold for starting azithromycin prophylaxis (because of its innate antiviral (IFN-boosting) property, at this time of enormous threat from COVID-19."

Intranasal corticosteroids in allergic rhinitis in COVID‐19 infected patients: An ARIA‐EAACI statement

"Some sources have suggested that “corticosteroids” should be avoided during the for SARS-CoV-2 epidemic. This advice is about the use of oral corticosteroids unless there is a clear indication for their use. Patients with asthma should not stop their prescribed inhaled corticosteroid controller medication (or prescribed oral corticosteroids). Stopping inhaled corticosteroids often leads to potentially dangerous worsening of asthma, and avoiding oral corticosteroids during severe asthma attacks may have serious consequences."

Postnatal SARS‐CoV‐2 Infection and Immunological Reaction: A Prospective Family Cohort Study

"The coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) appears milder in children but little is known about neonates and about the chains of infections after delivery.  When in early March 2020 a midwife in our large maternity and perinatal center returned from vacation in Ischgl, Austria, she triggered a COVID‐19 outbreak affecting 36 midwives, nurses and doctors. We reported previously on the successful containment of this outbreak and characterized the clinical symptoms and immunoglobulin development in staff members exposed to SARS‐CoV‐2."

African American children are at higher risk for COVID‐19 infection

"Infection by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), the viral etiology of the novel coronavirus disease 2019 (COVID‐19), was first reported in Wuhan, China in late 2019. Peculiarly, the virus has not caused significant impact on pediatric populations, unlike other coronaviruses (1). Children comprise only 1.7% of COVID‐19 positive cases in the United States (2). Furthermore, children are noted to have a milder disease course (3, 4). However, much is unknown about the age, gender and race risk factors of COVID‐19 among children. There has been recent evidence suggestive of higher rates of COVID‐19 and related fatality rates in African American adult communities around the United States(5). However, there is limited data, to our knowledge, whether any race or ethnicity group is at higher risk for COVID‐19 infection in children."

Coronavirus infection and allergies: what do we know?

"Viral infections are well-known risk factors for an exacerbation of asthma. In the study by Yang et al., 40% of the COVID-19 patients with critical symptoms had an underlying long-term disease before the infection. Another study of 140 cases from Wuhan (China) did not report allergic diseases as co-morbidities among severe cases. However, more information needs to be gathered and analyzed to create reliable reports on risk factors for severe COVID-19."

First antibody trial launched in COVID-19 patients

"The article describes the initiation of the first clinical trial (ClinicalTrials.gov LY-CoV555) that uses monoclonal antibody binding S-protein of SARS-Cov-2 virus. The antibody was designed using the most potent clones of B cells from COVID-19 patients. Before vaccine available the access to the highly specific monoclonal antibody would be very useful and might enrich treatment strategies in COVID-19."

SARS-CoV-2 receptor ACE2 is an interferon-stimulated gene in human airway epithelial cells and is detected in specific cell subsets across tissues

"Angiotensin-converting enzyme (ACE)2 receptor, an entry receptor for SARS-CoV and present on type 2 pneumocytes in the lung, ileal absorptive enterocytes, and nasal goblet secretory cells in nasal mucosa.
This paper shows, that ACE2 expression is upregulated by Type 1 IFNs. Furthermore it suggests that SARS-CoV-2 may use species-specific interferon up-regulation of ACE2, a mediator that protects tissues during lung damage, to increase infection. Hence type 1 IFNs, that drive anti-viral immunity on one hand, may paradoxically promote SARS-CoV-2 expansion by upregulating ACE2 expression on the other. As the type 1 IFN regulation in asthma might be impaired, these observations also might be related to the observed underrepresentation of severe Covid-19 among patients with asthma."

Furthermore, as the novel coronavirus SARSCoV-2 causing COVID-19 uses the ACE2 receptor for cell entry. it is notable that ACE2 is highly expressed in type II alveolar cells in the lungs, where ApoE is one of the highly co-expressed genes."

"This is a binational (Italian – Chinese) multicenter prospective study to assess cutaneous involvement in COVID-19, performed between 1.01-15.03.2020. The authors state that the dermatological manifestations could not be correlated to COVID-19 severity. Diffuse petechiae, gravity-dependent and multiple, generalized palpable purpura, and acroischemia (primarily finger/toe cyanosis, but no skin bulla nor dry gangrene) were seen in severe cases. Skin manifestations were observed in only 7.8% of the cohort, and these skin findings are generally mild and self-limiting and do not correlate with overall prognosis.”

Biologics increase the risk of SARS-CoV-2 infection and hospitalization, but not ICU admission and death: real-life data from a large cohort during RED-ZONE declaration

"Single center case-control study in Lombardia, Italy, of 1193 psoriasis patients treated with biologics compared to the Lombardia population as controls, assessing the risk of contracting COVID-19, and analysing mortality, and ICU admission rates. Furthermore severity of COVID-19 disease was reviewed.
Included psoriasis patients were adults, had moderate to severe disease and used approved anti-psoriatic monotherapy in the maintaining phase. Used medications include: TNFalpha inhibitors, IL 12/23 inhibitors, IL 17, IL 23 inhibitors and small molecules. Demographic and clinical characteristics of cases and controls were similar.
Patients under biologicals were at higher risk of testing positive for COVID 19 (OR 3.43(95% CI 2.25-5.75), more at risk of being self quarantained at home (OR 9.05) and more at risk of being hospitalized (OR 3.49) compared to controls. There was no statistical higher risk of ICU admission or death.
Authors discuss the fact that patients on biologicals might be at risk for respiratory infections, but the detrimental hyperinflammatory phase of COVID-19 as seen in the regular population occurred not in this study group and therefore might have protecte dpatients on biologicals from progression to extrapulmonary manifestations and death.
Limitations: there has not been and adjustment for, i.e. COPD patients or other patients with a known increased risk of severe COVID-19 disease. Furthermore, there hasn’t been a detailed sub analysis of which inhibitors are more or less effective at potentially preventing severe COVID-19. It is important to acknowledge that psoriatic patients on biologicals do show an increased risk of contracting mild-to-moderate COVID-19
Questions for further research include the role of the blocked interleukins in COVID-19. Does a similar pattern occur in i.e. asthma patients on asthma biologicals?"

Association of Respiratory Allergy, Asthma and Expression of the SARS-CoV-2 Receptor, ACE2

"Asthma and respiratory allergies have not been identified as risk factor for severe Covid-19 disease in case series till now. This paper describes features that could be associated with this diminished risk. In 3 different asthma/allergy cohorts, it was examined whether ACE2 (the receptor for SARS-Cov-2 entry) expression on airway cells was reduced. Allergen sensitisation and allergen exposure was strongly associated with reduced ACE2 expression in all cohorts. This might be mediated by type 2 inflammation, as IL-13 reduced ACE2 in bronchial and nasal epithelium; non-atopic asthma was not associated with this reduction. The role of biological treatment for allergic or type 2 high asthma and SARS-Cov-2 susceptibility is yet unknown. The relation between type 2 inflammatory processes and SARS-Cov-2 disease severity could identify novel therapeutic strategies.

Position statement of expert panel of the Polish Allergology Society (PTA) on the management of patients with bronchial asthma and allergic diseases during the SARS-CoV-2 pandemic

"The dynamically changing epidemiological situation related to SARS-CoV-2 infection poses challenges also for allergists. Both allergic diseases affecting many organs, especially the respiratory system, and the procedures used by allergists give rise a number of questions about
the proper procedures during the pandemic. This position statement aims to provide allergists with recommendations on the proper management of allergic patients in the current epidemiological situation.."

COVID-19: Pandemic Contingency Planning for the Allergy and Immunology Clinic

"In the event of a global infectious pandemic, drastic measures may be needed that limit or require adjustment of ambulatory allergy services. However, no rationale for how to prioritize service shut down and patient care exists. A consensus-based ad-hoc expert panel of allergy/immunology specialists from the United States and Canada developed a service and patient prioritization schematic to temporarily triage allergy/immunology services."

DGAKI statement on asthma and COVID-19

"AIT and COVID-19
March 18, 2020
Dear colleagues,

In the past few days, we have received more and more inquiries regarding the administration of allergen immunotherapy (AIT, also hyposensitization or specific immunotherapy) in times of the COVID-19 pandemic.
If possible, AIT treatments should continue. We would like to make the following recommendations:

When carrying out AIT, the product information for the AIT products must be observed and followed.
AIT in the form of subcutaneous injections (SCIT) or in the form of (sublingual) drops or tablets (SLIT) can be continued in symptom-free and healthy patients and the therapy regimen should not be interrupted.

If signs of infection such as fever, unclear cough or reduced general condition occur, AIT should be stopped and continued at a later (symptom-free) time-point . If SCIT is interrupted, the dose has to be adjusted by the treating doctor and according to the recommendations of the manufacturer. The resumption of SLIT should be carried out under medical supervision.

Prof. Dr. med. O. Pfaar, board member of DGAKI
Prof. Dr. me. Margitta Worm, President of the DGAKI"
