ABSTRACT

BACKGROUND: Biologics are an effective therapy for severe asthma. Home administration of biologics by patients is likely to facilitate their accessibility. Yet little is known about patients' and health care providers' (HCPs) perceptions regarding home administration of biologics. OBJECTIVE: The aim of this study is to create more insight into the perceptions and experiences of patients and HCPs regarding home administration of biologics in the context of the treatment of severe asthma. METHODS: A qualitative international study was performed in the Netherlands, United States, Australia, and United Kingdom. In each country, 2 focus groups were held with potential/recent and long-term users of biologics at home. Prior to the focus groups, patients were prompted with themes on online forums. For triangulation purposes, interviews were held with HCPs to discuss salient findings from forums and focus groups. Data were analyzed with qualitative content analysis. RESULTS: In total, 75 patients participated in the forums, of which 40 participated in the focus groups. Furthermore, 12 HCPs were interviewed. The following overarching themes were identified: living with severe asthma; practical aspects of using biologics; the role of HCPs regarding biologics; social support from family, friends, and others; effectiveness of biologics and other treatments; side effects of biologics. CONCLUSIONS: This study showed that, for those using biologics for severe asthma, the benefits of home administration of biologics usually outweigh inconvenience and side effects. Guided practice, accessible support contact, and monitoring including social support should be central in the transition from hospital to home administration of asthma biologics.

ABSTRACT

Background Patients on immunosuppressive drugs have been excluded from COVID-19 vaccines trials, creating concerns regarding their efficacy. Aims To explore the humoral response to COVID-19 vaccines in patients with inflammatory bowel disease (IBD) Methods Effectiveness and Safety of COVID-19 Vaccine in Patients with Inflammatory Bowel Disease (IBD) Treated with Immunomodulatory or Biological Drugs (ESCAPE-IBD) is a prospective, multicentre study promoted by the Italian Group for the study of Inflammatory Bowel Disease. We present data on serological response eight weeks after the second dose of COVID-19 vaccination in IBD patients and healthy controls (HCs). Results 1076 patients with IBD and 1126 HCs were analyzed. Seropositivity for anti-SARS-CoV-2 IgG was reported for most IBD patients, even if with a lesser rate compared with HCs (92.1% vs. 97.9%;p<0.001). HCs had higher antibody concentrations (median OD 8.72 [IQR 5.2-14-2]) compared to the whole cohort of IBD patients (median OD 1.54 [IQR 0.8-3.6];p<0.001) and the subgroup of IBD patients (n=280) without any treatment or on aminosalicylates only (median OD 1.72 [IQR 1.0–4.1];p<0.001). Conclusions Although most IBD patients showed seropositivity after COVID-19 vaccines, the magnitude of the humoral response was significantly lower than in HCs. Differently from other studies, these findings seem to be mostly unrelated to the use of immune-modifying treatments (ClinicalTrials.govID:NCT04769258).

ABSTRACT

Purpose: There has been concern that asthma and chronic obstructive pulmonary disease [COPD] increase the risk of developing and exacerbating COVID-19. The effect of medications such as inhaled corticosteroids (ICS) and biologics on COVID-19 is unclear. This systematic literature review analyzed the published evidence on epidemiology and the burden of illness of asthma and COPD, and the use of baseline medicines among COVID-19 populations. Patients and Methods: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, Embase®, MEDLINE® and Cochrane were searched (January 2019-August 2021). The prevalence of asthma or COPD among COVID-19 populations was compared to the country-specific populations. Odds ratios (ORs) were estimated to compare healthcare resource utilization (HCRU) rates, and meta-analyses of outcomes were estimated from age-adjusted ORs (aORs) or hazard ratios (aHRs). Meta-analyses of COVID-19 outcomes were conducted using random effects models for binary outcomes. Results: Given the number and heterogeneity of studies, only 183 high-quality studies were analyzed, which reported hospitalization, intensive care unit (ICU) admissions, ventilation/intubation, or mortality. Asthma patients were not at increased risk for COVID-19-related hospitalization (OR = 1.05, 95% CI: 0.92 to 1.20), ICU admission (OR = 1.21, 95% CI: 0.99 to 1.1.48), ventilation/intubation (OR = 1.24, 95% CI: 0.95 to 1.62), or mortality (OR = 0.85, 95% CI: 0.75 to 0.96). Accounting for confounding variables, COPD patients were at higher risk of hospitalization (aOR = 1.45, 95% CI: 1.30 to 1.61), ICU admission (aOR = 1.28, 95% CI: 1.08 to 1.51), and mortality (aOR = 1.41, 95% CI: 1.37 to 1.65). Sixty-five studies reported outcomes associated with ICS or biologic use. There was limited evidence that ICS or biologics significantly impacted the risk of SARS-CoV-2 infection, HCRU, or mortality in asthma or COPD patients. Conclusion: In high-quality studies included, patients with asthma were not at significantly higher odds for adverse COVID-19-related outcomes, while patients with COPD were at higher odds. There was no clear evidence that baseline medication affected outcomes. Registration: PROSPERO (CRD42021233963).

ABSTRACT

Asthma is a chronic inflammatory disease of the airways characterized by varying and recurrent symptoms, reversible airway obstruction, and bronchospasm. In this paper reviews clinical important studies on asthma between March 2021 and February 2022.
A study on the relationship between asthma and chronic rhinosinusitis, bronchiectasis, and hormone replacement therapy was published, and a journal on the usefulness of fractional exhaled nitric oxide for the prediction of severe acute exacerbation was also introduced. Studies on the effect of inhaler, one of the most important treatments for asthma, and studies to control severe asthma continued, and phase 2 and 3 studies of new biologics were also published. As the COVID-19 pandemic has been prolonged, many studies have explored the prevalence and mortality of COVID-19 infection in asthma patients.

ABSTRACT

INTRODUCTION: Given the increased infectious risk associated with biologics, particularly with TNFα inhibitors, concerns were raised over the safety of these agents in relation to SARS-CoV-2 infection. Furthermore, the impact of biologics on SARS-CoV-2 vaccination was questioned. AREAS COVERED: In this review, studies conducted on patients with moderate to severe plaque psoriasis treated with biologics during the COVID-19 pandemic have been analyzed, including 1) the safety of biologics in psoriatic patients in terms of increased risk and/or worse outcome of SARS-CoV-2 infection; and 2) whether biologic agents could affect the safety and response to SARS-CoV-2 vaccines in psoriatic patients. EXPERT OPINION: Current evidence indicates that the use of biologics in psoriatic patients does not seem to be associated with an increased COVID-19 infection risk or worse outcome, with TNFα inhibitors being even protective of severe COVID-19 relative to other treatments or no treatment at all. Furthermore, biologic treatment does not seem to have a significant impact on the response and safety of vaccines in patients with psoriasis treated with biologics. However, uncertainty remains given the limitations of current studies which are often of short duration, limited sample sizes and do not stratify on specific biologic classes.

ABSTRACT

Novel biologic therapies have revolutionized the treatment of psoriasis and atopic dermatitis. Although they are generally safe, they are immunomodulatory and therefore unique considerations apply in regards to infections and vaccine administration. This review aims to provide a clear and practical guide for dermatologists or other healthcare providers to reference when caring for psoriasis or atopic dermatitis patients being treated with biologic therapies using currently available guidelines and clinical data. Vaccinations for approved biologics including TNF alpha, IL-12/23, IL-23, IL-17, and IL-4/13 inhibitors will be discussed, with a special note on current COVID-19 vaccination recommendations.

ABSTRACT

Background: The COVID-19 pandemic has led to widespread changes in medical care. However, it is still unclear to what extent the care of patients suffering from moderate-to-severe psoriasis, chronic spontaneous urticaria or atopic dermatitis has been affected. Objectives: This study was conducted to determine the impact of the SARS-CoV-2 pandemic on medical care in dermatological practices, focusing on physicians' concerns related to susceptibility to infections in combination with different treatment modalities. Materials & Methods: Dermatologists working in medical offices in the German federal states of Bavaria and Lower Saxony participated in a cross-sectional, non-interventional, questionnaire-based study investigating the influence of COVID-19 on dermatological care. The study was performed after the first wave of the coronavirus pandemic in July/August, 2020. Results: A total of 195 dermatologists participated in the study. Almost one in five practices were closed for at least one week during the pandemic. The care of patients with chronic inflammatory skin diseases was impaired, affecting diagnostic investigation. Physicians stated that the pandemic substantially influenced systemic therapy. Nearly half of physicians surveyed were concerned about increased susceptibility to infections under biological therapy. No significant differences were identified between the German federal states of Bavaria and Lower Saxony in the south and north of Germany, respectively. Conclusion: This study reveals a significant impact of the COVID-19 pandemic on the care of dermatological patients in medical offices in Germany. New management modalities and continuous education are needed to improve care in pandemic situations.

ABSTRACT

BACKGROUND: In response to the COVID-19 pandemic, the CDC issued guidance advising patients and providers to adopt social distancing practices such as home-based infusions (H-BI). METHODS: We performed a mixed methods evaluation to summarize perceptions, concerns, and experiences with H-BI among all inflammatory bowel disease patients 18-90 years of age who transitioned to home-based infliximab or vedolizumab infusions between March to July 2020 at a tertiary care center. Semi-structured interviews were conducted and analyzed using an iterative, inductive thematic approach. Baseline characteristics and outcome on safety, COVID-19 transmission, delays in infusions, and H-BI persistence were collected. RESULTS: Of the 57 participants who transitioned to H-BI, 20 (33%) responded. Four major categories and six major themes related to expectations, experience, perceived safety, and logistical factors were identified. Initial perceptions were mixed, however these resolved. One patient developed COVID-19, one patient experienced an adverse event, 12 (21%) patients experienced an infusion delay, and 6 (11%) patients transitioned from H-BI. DISCUSSION: Despite mixed initial perceptions, respondents had a positive experience with most respondents planning to continue H-BI after the pandemic resolves. Several real-world actionable barriers were identified related to scheduling, communication between stakeholders, and nursing quality. No major safety concerns were identified.

ABSTRACT

BACKGROUND: Vaccination has been effective in preventing COVID-19 infections and related mortality. However, waning immunity after two-dose vaccination prompted health authorities to recommend a third dose of COVID-19 vaccine to boost immunity. The aim of our study was to assess willingness to receive a third (booster) dose among patients with inflammatory bowel disease (IBD). METHODS: A cross-sectional study was performed at an IBD tertiary care center. Patients were recruited at the infusion room from 1 January 2022 to 31 March 2022. The primary outcome was the prevalence of a third (booster) dose of the BNT162b2 vaccine in infliximab- or vedolizumab-treated patients with IBD. The secondary outcome evaluated whether the prevalence of a third (booster) dose of the BNT162b2 vaccine differed based on type of COVID-19 vaccine, gender, age, type of biologic therapy, and citizenship. RESULTS: In total, 499 patients with IBD were included in this study. The median age was 34.5 years, and 60% had ulcerative colitis (UC). Among the study participants, 302 (60.5%) patients were vaccinated with BNT162b2, and 197 (39.5%) were vaccinated with ChAdOx1 nCoV-19. Of the total number of participants, 400 (80.2%) were receiving infliximab, and 99 (19.8%) were receiving vedolizumab. Overall, 290 (58.1%) of the included patients were willing to receive the third (booster) dose. Patients vaccinated with BNT162b2 were more likely to be willing to receive a booster dose compared to patients vaccinated with ChAdOx1 nCoV-19 (201 (66.5%) vs. 103 (52.0%), p = 0.014). Infliximab-treated patients were more likely to be willing to receive a booster dose compared to patients receiving vedolizumab (310 (77.5%) vs. 62 (62.6%), p = 0.002). There was no statistical difference in willingness to receive a booster dose in terms of age, nationality, or gender. CONCLUSIONS: The percentage of patients with IBD willing to receive or having already received a third (booster) dose of BNT162b2 vaccine was lower compared to the general population. In addition, patients who received two doses of BNT162b2 vaccines were more likely to be willing to receive a third (booster) dose compared to patients who received ChAdOx1 nCoV-19. Patients treated with infliximab were more likely to be willing to receive a third (booster) dose of COVID-19 vaccine.

ABSTRACT

Introduction: Asthma, along with inhaled steroids, was initially considered a risk factor for worse clinical outcomes in COVID-19. This was related to the higher morbidity observed in asthma patients during previous viral outbreaks. This retrospective study aimed at evaluating the prevalence of asthma among patients admitted due to SARS-CoV-2 infection as well as the impact of inhaled therapies on their outcomes. Furthermore, a comparison between patients with asthma, COPD and the general population was made. Methods: All COVID-19 inpatients were recruited between February and July 2020 from four large hospitals in Northwest Italy. Data concerning medical history, the Charlson Comorbidity Index (CCI) and the hospital stay, including length, drugs and COVID-19 complications (respiratory failure, lung involvement, and the need for respiratory support) were collected, as well as the type of discharge. Results: patients with asthma required high-flow oxygen therapy (33.3 vs. 14.3%, p = 0.001) and invasive mechanical ventilation (17.9 vs. 9.5%, p = 0.048) more frequently when compared to the general population, but no other difference was observed. Moreover, asthma patients were generally younger than patients with COPD (59.2 vs. 76.8 years, p < 0.001), they showed both a lower mortality rate (15.4 vs. 39.4%, p < 0.001) and a lower CCI (3.4 vs. 6.2, p < 0.001). Patients with asthma in regular therapy with ICS at home had significantly shorter hospital stay compared to those with no treatments (25.2 vs. 11.3 days, p = 0.024). Discussion: Our study showed that asthma is not associated with worse outcomes of COVID-19, despite the higher need for respiratory support compared with the general population, while the use of ICS allowed for a shorter hospital stay. In addition, the comparison of asthma with COPD patients confirmed the greater frailty of the latter, according to their multiple comorbidities.

ABSTRACT

INTRODUCTION: Psoriasis affects children with a considerable burden in early life. Treating pediatric psoriasis is challenging also because of the lack of updated specific guidelines. With the recent approval of several biologics for pediatric psoriasis and the ongoing COVID-19 pandemic, the management of young psoriatic patients is facing major changes. A revision of treatment recommendations is therefore needed. METHODS: In September 2021, a board of six Italian dermatologists convened to update treatment recommendations. The board issued evidence- and consensus-based statements covering relevant areas of pediatric psoriasis, namely: assessment of psoriasis severity, management of children with psoriasis, and treatment of pediatric psoriasis. To reach consensus, the statements were submitted to a panel of 24 experts in a Delphi process performed entirely via videoconference. A treatment algorithm was produced. RESULTS: There was full consensus that psoriasis severity is determined by the extension/severity of skin lesions, site of lesions, and impact on patient quality of life. Agreement was reached on the need for a multidisciplinary approach to pediatric psoriasis and the importance of patient/parents education. The relevance of vaccinations, including COVID-19 vaccination, for psoriatic children was acknowledged by all participants. Management issues that initially failed to reach consensus included the screening for psoriasis comorbidities and early treatment with biologics to prevent them and the use of telemedicine to facilitate patient follow-up. There was full consensus that topical corticosteroids are the first choice for the treatment of mild pediatric psoriasis, while phototherapy and systemic therapy are used in children with moderate-severe psoriasis. According to the proposed treatment algorithm, biologics are the first line of systemic therapy. CONCLUSIONS: Targeted systemic therapies are changing the treatment of moderate-severe pediatric psoriasis, while topical corticosteroids continue to be the first choice for mild disease. Children-centered research is needed to further improve the treatment of pediatric psoriasis.

ABSTRACT

Breakthroughs in biotechnology, globalizing intellectual property rights legislations, and growing venture capital in the past thirty years have given rise to new forms of capitalist accumulation that scholars called biocapitalism. Bioscientific knowledge under biocapitalism is increasingly parceled out from a global common to private enclosures for biotech and pharmaceutical companies, contributing to vast inequalities and fractures of global access to innovation evident in the COVID-19 pandemic. The assetization and financialization of knowledge have shifted the ground of innovation from competitive commodity production and exchanges to generating, managing, and commercializing patents and associated monopoly rights, thus raising the challenges of innovation for those developing countries specialized in production. Many Asian countries have invested heavily in biomedical sciences to enhance their knowledge assets but had limited success in translating the scientific development to a globally significant biomedical industry. This article discusses the evolution of China’s biomedical industry from a technological laggard to a recent innovation boom after a regulatory overhaul in 2015. Analyzing the patent collaborative networks of China’s biomedical industry since 2003, we found the central roles of domestic public research institutions, in contrast to multinational corporations, as cutting-edge knowledge providers. We argue that China’s path of the biomedical industry is distinct from its other technology industries that rely on multinational corporations for core knowledge. It represents a national articulation in response to global biocapitalism by situating the domestic research institutions and biomedical firms at the center of knowledge assets production and engaging globally in the science and drug regulatory systems.

ABSTRACT

Coronavirus disease 2019 (COVID-19) was first reported in late December 2019 and, since then, has rapidly taken over the globe, with the scientific world furiously working to gather more data on its eff ect on people with and without concurrent conditions. The dysregulation of the immune system noted in COVID-19 patients is said to be similar to that seen with psoriasis. The pandemic has a_ ected the management of psoriasis, not only for those under treatment but also those about to begin a new therapy. There has been an increasing number of studies in the current literature focusing on the relationship between psoriasis and COVID-19, offering different perspectives. This is a summary of available data in PubMed supplemented by a manual review of reference lists of included articles. There may be lack of robust evidence to drive approaches to the management of psoriasis during the pandemic;however, we hope that the current literature may provide some clues for safety considerations. The conclusion of this article is that each approach to treatment should be personalized, weighing the benefits and risks in each case separately. © 2021 Matrix Medical Communications.

ABSTRACT

Much of the literature involving COVID-19 and chronic inflammatory dermatological conditions have focused on the safety of immunomodulatory therapy in the setting of this highly infectious virus. While general mortality associated with the infection and vaccine has been studied in depth, the effects of the virus and vaccine on inflammatory skin disease states have not been. It is well known that psoriasis can be triggered by stress, infection, certain medications, and, although not as common, vaccinations. Further, existing literature has briefly commented on psoriasis flares after COVID vaccination, but these have not touched on flares among their patients' current therapy, nor flares after COVID infection. In this case report, we report five cases observed at our institution over the last year of either new-onset psoriasis or flares of previously well-controlled psoriasis shortly after infection with COVID-19 or COVID-19 vaccination, with no other identifiable triggers. These cases can serve to raise awareness of issues related to managing stubborn psoriatic flares and bring to the forefront conversations that are likely to arise with our patients regarding the risks and benefits of COVID vaccination and boosters. While the definitive etiology of the association between COVID and psoriasis remains unclear, it is important that the dermatologic community be aware when evaluating patients with new-onset or worsening psoriasis as we move forward in times of this COVID-19 era.

ABSTRACT

This systematic review aimed to reevaluate the available evidence of the use of biologics as treatment candidates for the treatment of severe and advanced COVID-19 disease; what are the rationale for their use, which are the most studied, and what kind of efficacy measures are described? A search through Cochrane, Embase, Pubmed, Medline, medrxiv.org, and Google scholar was performed on the use of biologic interventions in COVID-19/SARS-CoV-2 infection, viral pneumonia, and sepsis, until 11 January 2022. Throughout the research, we identified 4821 records, of which 90 were selected for qualitative analysis. Amongst the results, we identified five popular targets of use: IL6 and IL1 inhibitors, interferons, mesenchymal stem cells treatment, and anti-spike antibodies. None of them offered conclusive evidence of their efficacy with consistency and statistical significance except for some studies with anti-spike antibodies; however, Il6 and IL1 inhibitors as well as interferons show encouraging data in terms of increased survival and favorable clinical course that require further studies with better methodology standardization.

ABSTRACT

Crohn's disease (CD) leads to a poor health-related quality of life (HRQoL). This review aimed to investigate the effect of biological agents and small-molecule drugs in improving the HRQoL of patients with moderate to severe CD. We adopted a systematic protocol to search PubMed and Cochrane Central Register of Controlled Trials (CENTRAL), which was supplemented with manual searches. Eligible studies were RCTs that matched the research objective based on population, intervention, comparison and outcomes. Studies in paediatric populations, reviews and conference abstracts were excluded. Covidence was used for screening and data extraction. We assessed all research findings using RoB2 and reported them narratively. We included 16 multicentre, multinational RCTs in this review. Of the 15 studies that compared the effect of an intervention to a placebo, 9 were induction studies and 6 investigated maintenance therapy. Of these, 13 studies showed a significant (p < 0.05) improvement in the HRQoL of patients with CD. One non-inferiority study compared the intervention with another active drug and favoured the intervention. This systematic review reported a substantial improvement in the HRQoL of patients with CD using biological agents and small-molecule drugs. These pharmaceutical substances have the potential to improve the HRQoL of patients with CD. However, further large clinical trials with long-term follow-up are essential to validate these findings.

ABSTRACT

BACKGROUND: At the beginning of the pandemic, there have been considerable concerns regarding coronavirus disease 2019 (COVID-19) severity and outcomes in patients with severe asthma treated with biologics. OBJECTIVE: To prospectively observe a cohort of severe asthmatics treated with biologics for the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and disease severity during the COVID-19 pandemic. METHODS: Physicians from centers treating patients with severe asthma all over Greece provided demographic and medical data regarding their patients treated with biologics. Physicians were also asked to follow up patients during the pandemic and to perform a polymerase chain reaction test in case of a suspected SARS-Cov-2 infection. RESULTS: Among the 591 severe asthmatics (63.5% female) included in the study, 219 (37.1%) were treated with omalizumab, 358 (60.6%) with mepolizumab, and 14 (2.4%) with benralizumab. In total, 26 patients (4.4%) had a confirmed SARS-CoV-2 infection, 9 (34.6%) of whom were admitted to the hospital because of severe COVID-19, and 1 required mechanical ventilation and died 19 days after admission. Of the 26 infected patients, 5 (19.2%) experienced asthma control deterioration, characterized as exacerbation that required treatment with systemic corticosteroids. The scheduled administration of the biological therapy was performed timely in all patients with the exception of 2, in whom it was postponed for 1 week according to their doctors' suggestion. CONCLUSION: Our study confirms that despite the initial concerns, SARS-CoV-2 infection is not more common in asthmatics treated with biologics compared with the general population, whereas the use of biologic treatments for severe asthma during the COVID-19 pandemic does not seem to be related to adverse outcomes from severe COVID-19.

ABSTRACT

Therapeutic drug monitoring (TDM) of biologics-encompassing the measurement of (trough) concentrations and anti-drug antibodies-is emerging as a valuable tool for clinical decision making. While this strategy needs further validation, attention on its implementation into the clinic is warranted. Rapid testing and easy sampling are key to its implementation. Here, we aimed to evaluate the feasibility and volunteers' perception of home microsampling for quantification of adalimumab (ADM) concentrations in psoriasis patients. In addition, we compared lateral flow testing (LFT) with enzyme-linked immunosorbent assay (ELISA). Patients participating in the SUPRA-A study (clinicaltrials.gov NCT04028713) were asked to participate in a substudy where volumetric absorptive microsampling (VAMS) was performed at home. At three time points, whole blood and corresponding serum samples were collected for ADM measurement using an in-house ELISA. In addition, the patients' perspective on microsampling was evaluated via a questionnaire. LFT-obtained ADM concentrations agreed very well with ELISA results (Pearson's correlation = 0.95 and R2 = 0.89). ADM concentrations determined in both capillary (via finger prick) and corresponding venous blood VAMS samples correlated strongly with serum concentrations (Pearson's correlation = 0.87). Our preliminary data (n = 7) on rapid testing and home-based microsampling are considered promising with regard to TDM implementation for adalimumab, warranting further research.
