ABSTRACT
Final Senate approval by a historically narrow 50-46 vote came only after the White House and Califf's supporters lobbied hard to gain sufficient support, a success that is very different from Califf's 89-4 approval back in 2016. Pressure to help control the high cost of prescription drugs will continue to drive FDA support for developing complex generic drugs and biosimilars. There is pressure to clarify rules governing e-cigarettes;a need to address serious health problems arising from contaminated food and seafood, including significant volumes of imported products;and the safety of cosmetic products, dietary supplements, sunscreens, and other non-prescription products raise additional complex issues.
ABSTRACT
In spelling out the data expected for such authorization, agency officials emphasized the importance of fully vetting the safety and efficacy of any new coronovirus vaccine through a highly transparent process to boost public confidence in the ability of vaccines to save lives. Countering vaccine hesitancy Through the debate, officials in the Center for Biologics Evaluation and Research (CBER) emphasized that the EUA safety data requirement was already well known to vaccine manufacturers and that one aim was to assure manufacturers that FDA would hold all vaccine development programs to the same standards. Center for Biologics Evaluation and Research (CBER) Director Peter Marks further emphasized that the guidance sought to reassure the public that granting an EUA would not be a rushed decision on vaccine safety and efficacy to meet political goals, and that a vaccine EUA would require more data than for the more usual emergency authorizations for therapeutics and other medical products.
ABSTRACT
The much-anticipated meeting of FDA's Vaccines and Related Biological Products Advisory Committee (VRBPAC) last month addressed a number of critical issues related to testing and approval of vaccines to prevent COVID-19 infection, including policies and data requirements for determining that a pandemic vaccine can be considered safe and effective, particularly when based on more limited, early clinical trial data. While studies sponsored by AstraZeneca and Johnson & Johnson's Janssen unit resumed soon after the meeting, the study pauses were described by researchers as a sign that clinical trial safety systems were working as intended, as the analysts determined the adverse events were unrelated to the test vaccine candidates. The aim is to gain further information on vaccine efficacy and side effects, including rare adverse events and fuller comparisons among patient groups with differences in age, sex, comorbidities, and ethnic characteristics.
ABSTRACT
BackgroundThe COVID-19 pandemic triggered serious challenges in the treatment of chronic diseases due to the lack of access to medical attention. Patients with rheumatic diseases (RD) must have adequate treatment compliance in order to reach and maintain remission or low activity of their diseases. Treatment suspension because of non-medical reasons might lead to disease activation and organ damage.ObjectivesIdentify the frequency of biologic treatment (bDMARD) suspension in patients with RD during the COVID-19 pandemic and determine the associated factors for suspension.MethodsIn this study we included all patients registered in the Mexican Biologics Adverse Events Registry (BIOBADAMEX), that started bDMARD before March 2019 and suspended treatment during the COVID-19 pandemic. We used descriptive statistic to analyze baseline characteristics and main treatment suspension causes. We used Chi[2] and Kruskal Wallis tests to analyze differences between groups.ResultsA total of 832 patients patients registered in BIOBADAMEX were included in this study, 143 (17%) suspended bDMARD during the COVID-19 pandemic. The main causes of suspension were inefficacy in 54 (38%) patients, followed by other motives in 49 (34%) patients from which 7 (5%) was loss of medical coverage. Adverse events and loss of patients to follow up were the motive in 16 (11%) and 15 (11%) patients respectively.When we compared the group that suspended bDMARD with the non-suspenders (Table 1), we found statistical differences in patient gender, with 125 (87%) female patients that suspended bDMARD, with a median age of 52 (42-60) years, and a treatment duration of 3.8 years.ConclusionIn our study we found that 17% of patients with RD suspended bDMARD treatment during the COVID-19 pandemic and that non-medical motives such as lack of patients follow up and loss of medical coverage due to unemployment were important motives. These results are related to the effect of the pandemic on other chronic diseases.Table 1.Patients baseline characteristicsPatients that did not suspended bDMARD during pandemic (n = 689)Patients that suspended bDMARD during pandemic (n = 143)pFemale gender, n(%)549 (79.7)125 (87.4)0.02Age, median (IQR)55 (45 – 63)52 (42 – 60)0.04Body mass index, median (IQR)26.4 (23 – 30.4)27.23 (24.2 – 30.46)0.13Social security, n(%)589 (85.5)128 (89.5)0.2Diagnosis0.7- Rheumatoid arthritis444 (64.4)97 (67.8)- Juvenil idiopathic athritis29 (4.2)2 (1.4)- Ankyosing sponylitis93 (13.5)19 (13.3)- Psoriasic arthritis43 (6.2)6 (4.2)- Systemic lupus erithematosus32 (4.6)9 (6.3)- Others48 (6.9)10 (6.9)Disease duration, median (IQR)11 (7 – 19.5)12 (6 - 18)0.95Comorbidities, n(%)305 (44.3)73 (51)0.08Previos biologic, n(%)249 (36.1)60 (42)0.1Treatment at pandemic iniciation, n(%)0.8 - Etanercept a34 (4.9)5 (3.5)- Infliximab a24 (3.5)5 (3.5)- Adalimumab130 (18.9)22 (15.4)- Rituximab a61 (8.9)25 (17.5)- Abatacept76 (11)20 (14)- Tocilizumab82 (11.9)18 (12.6)- Certolizumab92 (13.4)28 (19.6)- Rituximab b7 (1)0- Golimumab36 (5.2)5 (3.5)- Tofacitinib14 (2)1 (0.7)- Infliximab b4 (0.5)2 (1.4)- Etanercept b31 (4.5)6 (4.2)- Baricitinib12 (1.7)1 (0.7)- Belimumab5 (0.7)1 (0.7)- Secukinumb8 (1.2)3 (2.1)Steroids use, n(%):254 (36.9)57 (39.9)0.2Steroids dose (mg), median (IQR)6 (5 – 10)6 (5 – 10)0.47DMARD use, n(%):538 (78.1)118 (82.5)0.1Treatment duration, median (IQR)5.06 (4.04 – 5.78)3.82 (3.35 – 4.95)0.001Suspension motive, n(%)NA- Inefficacy-54 (37.8)- Adverse event-16 (11.2)- Pregnancy-2 (1.4)- Loss of patient-15 (10.5)- Remission-7 (4.9)- Others-49 (34.2)Adverse events, n(%):102 (14.8)24 (16.8)0.3- Severe, n(%)13 (1.9)5 (3.5)0.4a original, b biosimilarREFERENCES:NIL.Acknowledgements:NIL.Disclosure of InterestsVijaya Rivera Teran: None declared, Daniel Xavier Xibille Friedmann: None declared, David Vega-Morales: None declared, Sandra Sicsik: None declared, Angel Castillo Ortiz: None declared, Fedra Irazoque-Palazuelos: None declared, Dafhne Miranda: None declared, Iris Jazmin Colunga-Pedraza: None declared, Julio Cesar Casasola: None declared, Omar Elo Muñoz-Monroy: None declared, Sandra Carrilo: None declared, Angélica Peña: None declared, Sergio Duran Barragan: None declared, Luis Francisco Valdés Corona: None declared, Estefanía Torres Valdéz: None declared, Azucena Ramos: None declared, Aleni Paz: None declared, ERICK ADRIAN ZAMORA-TEHOZOL: None declared, Deshire Alpizar-Rodriguez Employee of: Scientific Advisor in GSK México.
ABSTRACT
According to market research, the pharmaceutical packaging sector is expected to grow at a compound annual rate of 7.4% between 2022 and 2031, reaching an estimated USS178.8 billion (€171.8 billion) by the end of the forecast period (1). "Pharmaceutical waste continues to be a huge problem, so to eliminate non-biodegradable and single-use plastics from the supply chain, more research is taking place around bio-based PET [polyethylene terephthalate]. "By designing a product's primary and secondary packaging well from the outset (including investing ample resources into the process), manufacturers can reduce the amount of materials used and wasted, test new eco materials, ensure safety compliance and efficacy, and benefit from cheaper transportation costs," Quelch surmises. [...]pharma companies can benefit from a packaging supplier with a true global footprint," he says.
ABSTRACT
According to Jens Kürten, group senior director, Communication and Marketing, Gerresheimer, there are nine megatrends that will both characterize and influence the pharmaceutical packaging market. Whether the drug be injected intravenously or subcutaneously, at home or in a hospital setting, there are various needs that should be considered prior to choosing the 'best-fit' packaging, he adds. [...]packaging requirements for pharmaceuticals change over time as the lifecycle of the drug continues," Stöcker states. [...]customers request more eco-friendly options to reduce or avoid plastic. [...]it has been necessary to design the packaging for the vaccines with these specific requirements in mind to ensure the safety and efficacy of the therapeutic product are protected.
ABSTRACT
According to Jeetendra Vaghjiani, senior director of clinical development and strategic marketing at Lonza, emerging biotech companies are reliant on contract development and manufacturing organizations (CDMOs) because of their development and manufacturing capacity, expertise, and flexibility. Because of the high attrition rate associated with drug development, the better your preclinical programme, the stronger the position you can establish in terms of programme design and patient identification (2). [...]because of the relative scarcity of approvals over the past decade, companies looking to capitalize on this new market are likely to require specialized knowledge to get through the approvals process.
ABSTRACT
[...]on 25 Nov. 2020, the European Commission (EC) announced the new Pharmaceutical Strategy for Europe, which is likely to result in significant changes to the European Union (EU) regulatory framework and will have a substantial impact on both the marketing of medicinal products and the strategic business planning of pharmaceutical companies (2). (2021), the priority areas are as follows: * The performance and adequacy of the current legislation * Unmet medical needs-with a definition or set of principles for "unmet medical needs" under discussion * Incentives for innovation, including the area of unmet needs and a reflexion on regulatory data and market exclusivity * Antimicrobial resistance that includes measures to support innovation of antibiotic development * Future-proofing the regulatory framework for novel products * Improved patient access to, and affordability of, medicines in the EU * Competitiveness of the European markets to ensure affordable medicines, including considering measures to support patients' access to affordable medicines * Encouraging the repurposing of off patent medicines * Ensuring security of supply of medicinal products in the EU * Ensuring high-quality manufacture and distribution in the EU including consideration of the need to strengthen or adapt good manufacturing practice (GMP) to reflect new manufacturing methodologies * Environmental challenges (4). Availability, accessibility, and affordability of medicinal products The section on 'Prioritising unmet medical needs' in the strategy reflects the belief within EU Bianca Piachaud-Moustakis is lead writer at PharmaVision, Pharmavision.co.uk. institutions that "current incentive models neither provide an adequate solution for unmet medical needs nor appropriately incentivise investments in innovation" (2).
ABSTRACT
The landscape for bioprocessing continues to evolve, driven by many externally imposed trends that have been combined with ongoing technological changes and internal progress in bioprocessing. [...]most ongoing bioprocessing-related trends are not new and are reported after they become evident or familiar, making it difficult to cite when a specific trend starts and ends. The Top 1000+ Global Biopharmaceutical Facilities Index currently tracks over 1900 facilities worldwide with total estimated bioreactor capacity now over 17.3 million litres, including >720 facilities with an >2000 L capacity (2). * More biosimilars, biobetters, and biogenerics, with continued expansion in developed markets and capturing growing market shares in developing countries, due to an increase in prices of the originals. * Single-use bioprocessing systems will continue to rapidly displace commercialscale stainless steel-based manufacturing, both at commercial manufacturing and clinical scales. * Expansion of second-source bioprocessing facilities to combat supply chain issues due to the COVID-19 pandemic. * Flexible manufacturing facilities, including modulation, further aided by the increased adoption of single-use bioprocessing systems. [...]of this build-up and investment, non-pandemic projects continue to be shifted out to contract manufacturing organizations (CMOs).
ABSTRACT
BackgroundCOVID-19 has shaped the world over the last 3 years. Although the risk for severe COVID-19 progression in children is low it might be aggravated by chronic rheumatic disease or treatment with immunosuppressive drugs.ObjectivesWe analyzed clinical data of COVID-19 cases among paediatric patients with rheumatic diseases reported to BIKER between March 2020 and December 2022.MethodsThe main task of the German BIKER (Biologics in Pediatric Rheumatology) registry is safety monitoring of biologic therapies in JIA. After the onset of the COVID-19 pandemic, the survey was expanded with a standardized form to proactively interview all participating centers about occurrence, presentation and outcome of SARS-CoV-2 infections in children with rheumatic diseases.ResultsA total of 68 centres participated in the survey. Clinical data from 928 COVID infections in 885 patients with rheumatic diseases could be analyzed. JIA was the most common diagnosis with (717 infections), followed by genetic autoinflammation (103 infections), systemic autoimmune diseases (78 infections), idiopathic uveitis (n=25), vasculitis (n=5).In 374 reported COVID infections (40%), patients were receiving conventional DMARDs, in 331 (36%) biologics, mainly TNF inhibitors (TNFi, n=241 (26%)). In 567 reports (61%) patients used either a biologic or a DMARD, in 339 reports patients (37%) did not use any antirheumatic medication including steroid.Over the last 3 years, COVID-19 occurred in Germany in 5 distinguishable waves, calendar weeks (CW) 10-30 in 2020, CW 21/2020 – 8/2021(both predominantly wild-type variant), CW 9-27 in 2021 (Alpha variant in the majority of infections), CW 28-51 in 2021 (Delta variant), since CW 52/2021 (several Omikron variants;Robert-Koch Institute: VOC_VOI_Tabelle.xlsx;live.com))In our cohort, patients with SARS-CoV-2 infection were slightly older during the 1st and 2nd wave (mean age 12.7+/-3.5 and 12.8+/-4.3 years) compared to the 4th and 5th wave with 11.4+/-3.9 and 11.4+/-4.2 years;p=0.01.160 asymptomatic SARS-CoV-2 infections were reported, frequencies of symptoms associated with COVID-19 are shown in table 1.Five patients were hospitalized for 4-7 days. A 3½-year-old female patient succumbed during the first wave with encephalopathy and respiratory failure. The patient had been treated with MTX and steroids for systemic JIA. Genetic testing revealed a congenital immunodeficiency. No other patient needed ventilation or intensive care. One case of uncomplicated PIMS in an MTX treated JIA patient was reported.The duration of SARS-CoV-2 infection-associated symptoms was markably shorter during the 5th wave with 6.7+/-5.1 days, compared with reports from the other 4 waves (Table1).The duration of symptoms was higher in MTX treated patients (10.2+/-8.4 days) compared to patients without treatment (7.7+/-10.8;p=0.004) or patients treated with TNFi (8.2+/-4.8, p=0.002). Although patients treated with steroids also had a longer duration of symptoms (9.7+/-7.0), this was not significant.ConclusionExcept for one patient with congenital immunodeficiency who died, no case of severe COVID-19 was reported in our cohort. At the time of infection, over 60% of patients had been treated with conventional DMARDs and/or biologics. Although MTX treated patients had a slightly longer duration of symptoms, antirheumatic treatment did not appear to have a negative impact on severity or outcome of SARS-CoV-2 infection.Table 1.Characteristics and frequency of symptoms in SARS-CoV-2 infectionsN or mean (SD)1st wave N=202nd wave N=843rd wave N=384th wave N=1245th wave N=662female14532775432age at COVID-19, years12.7 (3.5)12.8 (4.3)11.8 (3.5)11.4 (3.9)11.4 (4.2)asymptomatic126132694duration of symptoms;days,11.9 (14.7)9.2 (7.0)14.1 (11.6)10.3 (7.6)6.7 (5.1)fever1218541306cough1015652245rhinitis5261344289headache4161227171sore throat61139132musculosceletal pain2751348loss of smell/taste71162113fatigue4882680dizziness122116gastrointestinal symptoms151864dyspnea1117pneumonia11bronchitis1REFERENCES:NIL.Acknowledgements:NIL.Disclosure of Inter stsAriane Klein Speakers bureau: Novartis, Toni Hospach Speakers bureau: Speaking fee Novartis and SOBI., Frank Dressler Speakers bureau: Abbvie, Novartis, Pfizer, Advisory Boards Novartis and Mylan, Daniel Windschall Grant/research support from: research funds by Novartis, Roche, Pfizer, Abbvie, Markus Hufnagel: None declared, Wolfgang Emminger: None declared, Sonja Mrusek: None declared, Peggy Ruehmer: None declared, Alexander Kühn: None declared, Philipp Bismarck: None declared, Maria Haller: None declared, Gerd Horneff Speakers bureau: Pfizer, Roche, MSD, Sobi, GSK, Sanofi, AbbVie, Chugai, Bayer, Novartis, Grant/research support from: Pfizer, Roche, MSD, AbbVie, Chugai, Novartis.
ABSTRACT
BackgroundBefore COVID pandemic, rheumatologists were not confident with telehealth for the need to adquire new technology, need of specific training and poorer reimbursement [1]. Two groups of rheumatoid arthritis (RA) patients have been identified in a study of PROMS-based telehealth use (2): the keen and the reluctant. We proposed teleconsultation followup with a whatsapp platform chatbot to our axial spondyloarthritis (AxSPA) patients with controlled disease and we asked them for preferences at the end of the study.ObjectivesTo explore the degree of acceptance of asynchronous telehealth followup with whatsapp platform chatbot among our controlled AxSPA patients under biological therapy, and to search for a patient profile more prone to telehealth consultation.MethodsA prospective study with retrospective control was performed, chosing AxSPA patients under biological therapy with stable disease, visited in our centre from 01/01 to 30/11/2021. We recruited 62 patients, but finally include 60 (2 quit for home moving or personal reasons). We offered them two teleconsultation visits (using their personal mobile), every four months, and a presential final visit one year after inclusion. The chatbot sends PROMS (BASDAI, VAS for patient global disease assessment, ASDAS, and 3 questions for extraarticular disease), and feedback and schedule for the following visits. In the case of lab test or PROMs deviation or when the patient asks for contact, he/she is phoned by nurse/doctor who solves the question and/or arranges an additional presential visit. We collect patient and disease characteristics (age, gender, educational level, employment, disease activity, duration and treatments), and patient´s satisfation and preferences in the final visit.ResultsWe included 60 patients (83,3% men), mean aged 48,22 years (SD 12,128), 36% under 45 years at inclusion. 27% had received primary, 33.9% secondary and 39% tertiary education. 83.3% were active working and only 10 patients were jobless or retired. They were Ankylosing Spondylitis (AS) (90%), HLA B27 positive (85%) with longstanding disease (mean 23 years, SD 12,8), and were receiving the first (71%), or the second (23%) biological therapy (51,7% tapered anti-TNF). 50% were never smokers and 70% presented no remarkable comorbidity;25% presented peripheral impairment, and over 40% extraarticular manifestations.At inclusion 93,3% were at remission/LDA by ASDAS/BASDAI-RCP and 4 patients were considered clinically controlled in spite of higher scores. At followup 3 patients with reduced dose needed to increase to standard dose of biological drug, with no other need of treatment change. There was no worsening from basal to final visits according BASDAI, BASFI, ASDAS-RCP or AsQOL.Patients final VAS score (1-10) assessment of telehealth consultation was very high: mean 9,14 (DS 1,498);91.7% ≥ 8 and 76.7% ≥ 9.83,3% preferred telehealth followup. There was a trend towards telehealth preferences in higher educational levels, and active working (86% vs 70%) but not statistically significant. We found no correlation with gender, age and disease characteristics tested.ConclusionAsynchronous teleconsultation seems promising, not inferior to presential consultation and preferred for follow-up by our AxSpa patients with stable disease with biological drugs. We met some "reluctant patients”, that were more inactive working and with lower educational levels, but the differences were not significant. Further reserarch is needed with this telehealth model in other age and disease populations (RA), in order to characterize the reluctant and keen patients.References[1]Muehlensiepen F, et al.

ABSTRACT
BackgroundThe use of telehealth in the control of rheumatic diseases had been scarce, but COVID pandemic forced to try alternatives to classic face-to-face consultation, and an overflow of telehealth consultations appeared, mainly synchronous (phone, video calls), and finally asynchronous. We try to demonstrate that asynchronous WhatsApp teleconsultation is a good alternative, at least for followup of patients that find it difficult to attend face-to-face visits. We chose axial spondyloarthritis (AxSPA) patients under biological therapy with controlled disease and we proposed teleconsultation with a WhatsApp platform chatbot created for this purpose. The chatbot sends PROMS (BASDAI, VAS for patient global disease assessment, ASDAs, and 3 questions for extraarticular disease), and receive feedback and schedule for the following visits.ObjectivesTo prove that teleconsultation through WhatsApp platform is not inferior to face-to-face consultation in terms of maintaining axial SPA patients disease controlled.MethodsProspective study with retrospective control of patients diagnosed of Axial SPA, fulfilling ASAS criteria and with stable disease under biological therapy for the previous year, recruited from 01 jan to 30 nov 2021. We recruited 62 patients, but two of them gave up (personal reasons, one moved to other region), so we finally include 60 patients. We offer them two teleconsultation visits with their personal mobile device, every four months, and a face-to-face final visit one year after inclusion. In the case of lab test or PROMs deviation or when the patient asks for contact (possible via WhatsApp) he/she is called up by the person in charge (nurse/doctor) that solves the question and arranges an additional presential visit if needed. We consider disease controlled if BASDAI <4, ASDAS < 2,1 or if in rheumatologist´s opinion there is no need to change treatment. We collect patient and disease information (age, gender, employment, characteristics of the disease, previous and actual treatment), activity (BASDAI, PCR, ASDAS), physical function (BASFI), and Quality of life (AsQol).Results60 patients (50 men, 83,3%) were included, mean aged 48,22 years (SD 12,128), 36% were under 45 years at the time of inclusion. They were mostly Ankylosing Spondylitis (AS) (90%;only 6 non radiographic SPA), positive HLA B27 (85%) and with longstanding disease (mean 23 years, SD 12,8), and only 6 patients less than five years. 25% had peripheral impairment (arthritis/dactylitis/enthesitis), and more than 40% presented extraarticular manifestations, mainly psoriasis (26,7%) and uveitis (21%)71,7% were under their first biological (TNF inhibitor, mostly adalimumab), 23,3% were refractory to the first, and 3 patients to at least two biologicals. 51,7% of patients were treated with tapered dose of TNF inhibitors. At inclusion 93,3 % presented remission/LDA by ASDAS/BASDAI-RCP. Only 4 patients included presented higher activity scores but were considered clinically controlled.Table 1.We did not find meaningful clinical differences between basal to final visits in BASDAI, BASFI, ASDAS-RCP or AsQOL.3 patients with reduced dose of biological drug needed to increase to standard dose with no other need to treatment adjustment.ConclusionWe consider asynchronous teleconsultation is promising, and not inferior to face to face consultation in terms of keeping disease control and quality of life, especially for follow-up in patients with stable rheumatic disease, The clinical results presented here are consistent with this considerations.AcknowledgementsGrupo INNOBIDE.Disclosure of InterestsNone Declared.
ABSTRACT
[...]ustekinumab concentrated solution and ustekinumab injection are the first IL-12/IL-23 inhibitors to be studied by EDQM for monograph development via the P4 process (13). First "horizontal standard" for biotherapeutic monographs Today, there are several TNF-alpha inhibitor products available, and manufacturers have used a wide variety of methods to assess the potency of these mAbs. Two other horizontal standards are currently being elaborated by EDQM: "Capillary Isoelectric Focusing for Recombinant Therapeutic ~ Monoclonal antibodies (2.5.44)" and "Size Exclusion Chromatography for Recombinant Therapeutic Monoclonal Antibodies (2.5.43)" (19). The final change to CGT standards is to general chapter "Raw Materials of Biological Origin for the Production of Cell-based Therapy Medicinal Products (5.2.12)."
ABSTRACT
This study aimed to evaluate if patients under biologics have a lower risk of psoriasis flares after coronavirus disease 2019 (COVID-19) vaccination than other psoriatic patients. Of 322 recently vaccinated patients admitted for psoriasis at the Dermatological Psoriasis Unit during January and February 2022, 316 (98%) had no psoriasis flares after COVID-19 vaccination (79% under biologic treatment, 21% not biologically treated) and 6 (2%) presented psoriasis flares after COVID-19 vaccination (33.3% under biologic treatment, 66.6% not biologically treated). Overall, psoriasis patients under biologic treatment, developed fewer psoriasis flares after COVID-19 vaccination (33.3%), than patients not under biologic treatment (66.6%) (p=0.0207; Fisher's exact test).

ABSTRACT
BackgroundPatients with severe asthma (SA) may be at higher risk of severe COVID-19 (C-19) illness. C-19 vaccines aim to reduce number and severity of infections. Patients with SA are often treated with maintenance oral corticosteroids (mOCS) and/or biologics- it is unknown if vaccines will generate the same protective responses in patients with SA on such therapies.AimsTo compare magnitude and range of post-vaccination (PV) antibody responses (IgG) in patients with SA on biologics, mOCS or high-dose inhaled corticosteroids (ICS) with healthy controls (HC) without asthma.To review temporal trends in PV IgG in patients with SAMethodsThe Virtus finger-prick quantitative C-19 antibody test was used to detect IgG levels 16–24 weeks post second-dose of the C-19 vaccine (123 AstraZeneca, 56 Pfizer, 5 Moderna). PV IgG levels were also measured in a subset of patients 6 weeks PV. IgG>0.2 AU was considered positive with range: very high >1.25 AU, high 0.751–1.25 AU, medium 0.401–0.75 AU and low 0.201–0.4 AU. SA was defined as per ATS/ERS criteria.ResultsPV IgG results were obtained from 127 patients with SA (84 on biologics, 13 mOCS and 46 ICS) and 57 HC. After adjusting for age, significantly fewer people with SA compared to HC had a positive PV IgG result (81% vs 95% p=0.016). Compared to HC (1.24 AU), lower median IgG levels were seen in patients on high dose ICS (1.02 AU, p=0.033) and mOCS (0.40 AU, p=0.017).Patients on biologics had high or very high IgG levels (omalizumab n=25, 0.80 AU;mepolizumab n=25, 1.07 AU;benralizumab n=34, 1.11 AU).Paired temporal measurements in 37 SA patients showed regression coefficient -0.005 (95%CI -0.006,-0.003) and can be interpreted as IgG decreases, on average, by 0.15 AU per month.ConclusionOverall, a higher proportion of patients with SA had a negative PV IgG level after receiving 2 doses of a C-19 vaccine. This was mainly seen in patients on mOCS while biologic use was not associated with reduced humoral antibody response. These results reinforce the need for booster vaccines in SA, especially in those on mOCS.
ABSTRACT
Background: Several COVID-19 vaccination rollout strategies are implemented. Real-world data from the large-scale, government-mandated Central Vaccination Center (CVC), Thailand, could be used for comparing the breakthrough infection, across all available COVID-19 vaccination profiles. Methods: This prospective cohort study combined the vaccine profiles from the CVC registry with three nationally validated outcome datasets to assess the breakthrough COVID-19 infection, hospitalization, and death among Thais individuals who received at least one dose of the COVID-19 vaccine. The outcomes were analyzed by comparing vaccine profiles to investigate the shot effect and homologous effect. Findings: Of 2,407,315 Thais who had at least one dose of COVID-19 vaccine, 63,469 (2.75%) had breakthrough infection, 42,001 (1.79%) had been hospitalized, and 431 (0.02%) died. Per one vaccination shot added, there was an 18% risk reduction of breakthrough infection (adjusted hazard ratio [HR] 0.82, 95% confidence interval [CI] 0.80-0.82), a 25% risk reduction of hospitalization (HR 0.75, 95% CI 0.73-0.76), and a 96% risk reduction of mortality (HR 0.04, 95% CI 0.03-0.06). The heterologous two-shot vaccine profiles had a higher protective effect against infection, hospitalization, and mortality compared to the homologous counterparts. Interpretation: COVID-19 breakthrough infection, hospitalization, and death differ across vaccination profiles that had a different number of shots and types of vaccines. Funding: This study did not involve any funding.

Administration of biologics is not necessary to be postponed due to SARS-CoV-2 infection.Constant-Load Exercise Versus High-Intensity Interval Training on Aerobic Fitness in Moderate-to-Severe Asthma: A Randomized Controlled Trial Aparecido da Silva et al 2596 What is already known about this topic? Bronchiectasis is expected to worsen the clinical and functional outcomes in patients with asthma, but limited data are available regarding the long-term effects of bronchiectasis on the clinical course of asthma. Data from this large, prospective study translate the OCS-sparing effect of mepolizumab in patients with severe asthma reported across randomized, placebo-controlled trials into real-world clinical effectiveness when used alongside standard of care.
