Impact of SARS-CoV-2/COVID-19 on Provision of Medical Care to Patients With Systemic Autoimmune Rheumatic Disease and the Practice of Rheumatology.

The SARS-CoV-2 pandemic has had a significant impact on the healthcare field that resulted in changes to the way safe and effective medical care is delivered. The effects range from service disruption including ambulatory clinic closure due to both patient and provider concerns, to lack of capacity in hospital services. In rheumatology, there were other effects including viral infection-related autoantibody production, concerns about the use of systemic immunosuppression in the presence of an infectious pandemic and even concerns for viral infection-induced flares of rheumatic disease. Coronavirus disease 2019 (COVID-19) led to the rapid adoption of innovative technologies that permitted the introduction and increased use of telemedicine via a number of platforms. Rapid discoveries and innovations led to the development of diagnostic and therapeutic agents in the management of COVID-19. Scientific advancement and discoveries around COVID-19 infection, symptoms, autoantibody production, chronic sequela and the repurposing of rheumatic immunosuppressive agents led to improved survival and an expanded role for the rheumatologist. Rheumatologists may sometimes be involved in the diagnosis and management of the hospitalized COVID-19 patient. In the ambulatory clinic, a rheumatologist also helps to differentiate between symptoms of long COVID and those of systemic autoimmune rheumatic disease (SARD). Rheumatologists must also grapple with the concerns related to immunosuppressive therapy and the risk of COVID-19 infections. In addition, there are concerns around vaccine effectiveness in people with SARD and those on immunosuppressive medications. Although the SARS-CoV-2 pandemic and the effects on healthcare resulted in difficulties, both patients and providers have risen to the challenge. The long-term outcome of COVID-19 for the medical system and rheumatologists in particular is not yet fully understood and will need further study. This review concentrates on the changing role of the rheumatologists, improved understanding of rheumatic disease and immunosuppressive therapies in the wake of the pandemic and how this has led to an improvement in the care of patients with COVID-19.

Risk and course of COVID-19 in immunosuppressed patients with myasthenia gravis.

BACKGROUND: Patients with myasthenia gravis (MG) are potentially prone for a severe COVID-19 course, but there are limited real-world data available on the risk associated with COVID-19 for patients with MG. Here, we investigate whether current immunosuppressive therapy (IST) influences the risk of SARS-CoV-2 infection and COVID-19 severity. METHODS: Data from the German myasthenia gravis registry were analyzed from May 2020 until June 2021 and included patient demographics, MG disease duration, comorbidities, current IST use, COVID-19 characteristics, and outcomes. Propensity score matching was employed to match MG patients with IST to those without, and multivariable binary logistic regression models were used to determine associations between IST with (1) symptomatic SARS-CoV-2 infection and (2) severe COVID-19 course, as measured by hospitalization or death. RESULTS: Of 1379 patients with MG, 95 (7%) patients (mean age 58 (standard deviation [SD] 18) presented with COVID-19, of which 76 (80%) received IST at time of infection. 32 patients (34%) were hospitalized due to COVID-19; a total of 11 patients (12%) died. IST was a risk factor for hospitalization or death in the group of COVID-19-affected MG patients (odds ratio [OR] 3.04, 95% confidence interval [CI] = 1.02-9.06, p = 0.046), but current IST was not associated with a higher risk for SARS-CoV-2 infection itself. DISCUSSION: In this national MG cohort study, current IST use was a risk factor for a severe disease course of COVID-19 but not for SARS-CoV-2 infection itself. These data support the consequent implementation of effective strategies to prevent COVID-19 in this high-risk group.

COVID vaccine recommendations in dermatologic patients on immunosuppressive agents: Lessons learned from pandemic.

Since SARS-CoV2 vaccines were approved without enough long-term monitoring due to emergent situations, some issues have been raised about timing and protocol of receiving them by patients treated by different immunosuppressive agents. Here, we present different aspects of SARS-CoV-2 vaccination in such patients in the field of dermatology. In brief, SARS-CoV-2 vaccination is recommended in all dermatologic patients, regardless of their disorders and therapeutic regimens. Nevertheless, special considerations should be given to the immunosuppressive therapy and its association with vaccination timing due to the decreased immunogenicity of vaccines in this setting. Novel biologic immunotherapies are advantageous over conventional systemic therapies not only in their safety and selective functions but also in this aspect that many of them do not affect vaccines immunogenicity.

SARS-CoV-2 vaccination and practical points in psoriasis patients: A narrative review.

SARS-CoV2 vaccines were approved without long-term monitoring due to emergent situations. This has raised some issues about timing and protocol of receiving vaccines in specific situations including patients with chronic inflammatory disorders such as psoriasis. Here, we present different aspects of SARS-CoV-2 infection and vaccination in psoriasis patients and aim to provide solutions to overcome the potential challenges. In brief, the benefits of vaccination outweigh the potential risk; vaccine-triggered de novo or flares of psoriasis is uncommon. As such, all psoriasis patients, especially those receiving systemic treatments including anti tumor necrosis factor agents, are strongly recommended to get SARS-CoV-2 vaccines. It is recommended that new immunosuppressive/immunomodulatory therapies be initiated at least 1 week after the second SARS-CoV-2 vaccine dose, if possible. In addition, in severe and active forms of psoriasis, it is better to delay vaccination until stabilization of the disease.

Systematic review of risk of SARS-CoV-2 infection and severity of COVID-19 with therapies approved to treat multiple sclerosis.

There is growing concern that multiple sclerosis (MS) patients on certain therapies may be at higher risk for severe coronavirus disease 2019 (COVID-19). We conducted a systematic literature review to examine the available data on U.S. therapies approved to treat MS and the risk of SARS-CoV-2 infection or severe COVID-19 outcomes. We conducted searches in PubMed, Embase, and the WHO COVID-19 database through May 2, 2021, and retrieved articles describing clinical data on therapies approved to treat MS and the risk of infection with SARS-CoV-2 or the effects of such therapies on clinical outcomes of COVID-19. The literature search identified a total of 411 articles: 97 in PubMed, 227 in Embase, and 87 in the WHO database. After excluding duplicates and screening, we identified 15 articles of interest. We identified an additional article through a broader secondary weekly search in PubMed. Thus, ultimately, we reviewed 16 observational studies. Available data, which suggest that MS patients treated with anti-CD20 monoclonal antibodies may be at increased risk for severe COVID-19, are subject to relevant limitations. Generally, studies did not identify increased risk for COVID-19 worsening with other therapies approved to treat MS. Based on observational data, biological plausibility, novelty of the drug-event association, and public health implications in a subpopulation with potential impaired response to the COVID-19 vaccines, this safety signal merits further monitoring.

SARS-CoV-2 serology after COVID-19 in multiple sclerosis: An international cohort study.

BACKGROUND: The MuSC-19 project is an Italian cohort study open to international partners that collects data on multiple sclerosis (MS) patients with COVID-19. During the second wave of the pandemic, serological tests became routinely available. OBJECTIVE: To evaluate the seroprevalence of anti-SARS-CoV-2 antibodies according to the use of disease-modifying therapy (DMT) in a subset of patients included in the MuSC-19 data set who had undergone a serological test. METHODS: We evaluated the association between positive serological test results and time elapsed since infection onset, age, sex, Expanded Disability Status Scale score, comorbidities and DMT exposure using a multivariable logistic model. RESULTS: Data were collected from 423 patients (345 from Italy, 61 from Turkey and 17 from Brazil) with a serological test performed during follow-up. Overall, 325 out of 423 tested patients (76.8%) had a positive serological test. At multivariate analysis, therapy with anti-CD20 was significantly associated with a reduced probability of developing antibodies after COVID-19 (odds ratio (OR) = 0.20, p = 0.002). CONCLUSION: Patients with MS maintain the capacity to develop humoral immune response against SARS-COV-2, although to a lesser extent when treated with anti-CD20 drugs. Overall, our results are reassuring with respect to the possibility to achieve sufficient immunization with vaccination.

SARS-CoV-2 (COVID-19) vaccination in dermatology patients on immunomodulatory and biologic agents: Recommendations from the Australasian Medical Dermatology Group.

As the phase III COVID-19 vaccine trials excluded patients on immunosuppressive treatments, or patients with significant autoimmunity, the Australasian Medical Dermatology Group make the following preliminary recommendations around COVID-19 vaccination in dermatology patients on immunomodulatory and/or biologic agents. Vaccination against COVID-19 is strongly encouraged for all patients on immunomodulatory drugs and/or biologic agents. There are currently insufficient data to recommend one COVID-19 vaccine or vaccine type (mRNA, recombinant, inactivated virus) over another. No specific additional risk in patients on immunomodulatory or biologic therapies has so far been identified. Data on vaccine efficacy in patients on immunomodulatory or biologic therapies are missing, so standard vaccination protocols are recommended until otherwise advised.
