Impact of the COVID-19 pandemic on the quality of care for juvenile idiopathic arthritis patients: insights from Thailand

BACKGROUND

The COVID-19 pandemic has significantly impacted individuals with chronic conditions. This investigation assessed the quality of care provided to pediatric and adolescent patients with juvenile idiopathic arthritis (JIA) during the pandemic in Thailand.

METHODS

This cross-sectional analysis enrolled JIA patients aged ≤ 18 years at an academic tertiary care facility from April 2022 to March 2023. Retrospective reviews were performed, complemented by patient and caregiver questionnaires to assess the pandemic's impact on care quality.

RESULTS

Seventy JIA patients (37 males, 33 females) with a mean age of 13.5 ± 3.1 years were included. A total of 41.4% of the caregivers reported negative impacts on JIA care due to the pandemic and the lockdown, and 31.4% of the patients experienced pandemic-related anxiety. A comparison between the pandemic and prepandemic periods revealed a higher incidence of active disease, although the difference was statistically nonsignificant (37.1% vs 14.2%, p = 0.106). Nonadherence significantly predicted active disease status (adjusted OR 15.04, 95% CI 2.48-91.15, p = 0.03). COVID-19 vaccinations were administered to 85.7% of patients; 52.8% of whom contracted mild COVID-19. Most patients (71.4%) postponed clinic visits; 36% due to lockdowns and 28% due to concerns about COVID-19 exposure in healthcare settings. The majority of patients received telephone JIA management advice from rheumatologists during the lockdown (91.4%).

CONCLUSIONS

The COVID-19 pandemic and associated lockdown measures affected the care of JIA patients, impacting both physical and mental health. Nonadherence was a critical factor in disease flare-ups. Telemedicine is indispensable for patient care.

Fatal hemophagocytic lymphohistiocytosis with intravascular large B-cell lymphoma following coronavirus disease 2019 vaccination in a patient with systemic lupus erythematosus: an intertwined case

Hemophagocytic lymphohistiocytosis (HLH) has been recognized as a rare adverse event following the coronavirus disease 2019 (COVID-19) vaccination. We report a case of neuropsychiatric symptoms and refractory HLH in a woman with systemic lupus erythematosus (SLE) after receiving her COVID-19 vaccine treated with belimumab, later found to have intravascular large B-cell lymphoma (IVLBCL) at autopsy. A 61-year-old woman with SLE was referred to our hospital because of impaired consciousness and fever. One month prior to consulting, she received her second COVID-19 vaccine dose. Afterward, her consciousness level decreased, and she developed a high fever. She tested negative for SARS-CoV-2. Neuropsychiatric SLE was suspected; therefore, glucocorticoid pulse therapy was initiated on day 1 and 8. She had thrombocytopenia, increased serum ferritin levels and hemophagocytosis. The patient was diagnosed with HLH and treated with etoposide, dexamethasone and cyclosporine. Despite treatment, the patient died on day 75; autopsy report findings suggested IVLBCL as the underlying cause of HLH. Differentiating comorbid conditions remains difficult; however, in the case of an atypical clinical presentation, other causes should be considered. Therefore, we speculate that the COVID-19 vaccination and her autoimmune condition may have expedited IVLBCL development.

A community-engaged approach to translate a Vaccine Hesitancy Scale into Haitian Creole

OBJECTIVE

Accurately translated health materials are needed to achieve equity in vaccine uptake among U.S. individuals with non-English language preferences. Verbatim translations may not capture the cultural and linguistic vernacular required to understand vaccine hesitancy. We leveraged a community-engaged approach to translate the Vaccine Hesitancy Scale (VHS) into Haitian Creole.

METHODS

Following the "WHO Guidelines on Translation and Adaptation of Instruments" and a community-engaged framework, a validated 10-question Vaccine Hesitancy Scale (VHS) underwent forward translation, expert panel review, back translation, and focus group pilot testing.

RESULTS

Haitian Creole-speaking translators included two community leaders, one community partner, one study team member, and 13 Haitian, greater Boston-based community members who participated in a focus group to pretest the survey. After four iterations, a linguistic and cultural translation of the VHS was created.

CONCLUSION

A community-engaged framework strengthened community partnerships and resulted in a culturally relevant Haitian Creole vaccine hesitancy scale.

Immunogenicity and safety of BNT162b2 vaccination in adolescents with systemic lupus erythematosus

OBJECTIVES

We evaluated the immunogenicity and safety of BNT162b2 vaccination in adolescents with systemic lupus erythematosus (adoSLE) receiving either high- or low-dose immunosuppressant (High-IS and Low-IS).

METHODS

Patients aged 12-18 years diagnosed with SLE were enrolled. High-IS was defined as >7.5 mg/day prednisolone or with other immunosuppressant, while Low-IS was defined as only ≤7.5 mg/day of prednisolone and no immunosuppressant. Two doses of BNT162b2 vaccination were given 4 weeks apart, followed by a booster (third) dose at 4-6 months later. Anti-spike receptor binding domain (anti-RBD) IgG against Wuhan, neutralising antibody (NT) against Wuhan and Omicron variants, and cellular immune response by IFN-γ-ELISpot assay were evaluated following vaccination. Adverse events (AEs) and SLE flare were monitored.

RESULTS

A total of 73 participants were enrolled, 40 and 33 in the High-IS and Low-IS group, respectively. At 4 weeks following the 2nd dose, overall anti-RBD IgG seropositivity was 97.3%, with no difference between the groups (p = .498). AdoSLE on High-IS had lower anti-RBD IgG (p < .001), Wuhan NT (p < .001), and IFN-γ-ELISpot (p = .022) than those on Low-IS. A 3rd dose induced significantly higher antibody responses than after the 2nd dose (p < .001) in both groups and established seroconversion against Omicron variants, with persistent lower antibody levels in High-IS group. SELENA-SLEDAI scores within 12 weeks after 2-dose vaccination was higher than before vaccination (3.1 vs 2.5; p < .036); however, the occurrence of disease flare by SELENA-SLEDAI flare index was not different after vaccination compared to before vaccination, consistent across groups. Non-severe AEs occurred similarly in both groups.

CONCLUSION

AdoSLE on High-IS induced lower SARS-CoV-2 vaccine immune responses than Low-IS. Vaccination can increase disease activity and requires close monitoring for disease flare.

COVID vaccine-induced lupus nephritis: Case report and review of the literature

Vaccines offer an effective strategy to prevent infectious diseases with minimal adverse effects. On rare occasions, vaccination can disrupt the immune response leading to induction of autoimmune diseases. We describe a case of new-onset lupus nephritis following COVID-19 vaccination with the first dose of the Pfizer vaccine. Her symptoms and lab values improved with steroids, hydroxychloroquine, and mycophenolate mofetil.

Understanding COVID-19 vaccine hesitancy in vasculitis patients

Objective

To identify the factors that impact COVID-19 vaccine decision-making in vaccine-hesitant vasculitis patients, and compare their perceptions with other rheumatology patients, given existence of data suggesting rheumatology patients may have disease-specific factors that influence their COVID-19 vaccine decision-making.

Methods

This cross-sectional study surveyed adult rheumatology patients from the Kaye Edmonton Clinic Rheumatology Clinic, in Canada, between June and August 2021, using an anonymous online questionnaire. Survey responses were analyzed for statistical differences using chi-square analysis.

Results

The COVID-19 Vaccine Perceptions Survey had a response rate of 70.9%. Of the total 231 respondents, 103 patients were diagnosed with vasculitis. At the time of the survey, 10.6% of vasculitis patients refused to receive a COVID-19 vaccine compared to 6.3% for other rheumatology patients. Compared to other rheumatology patients, vaccine-hesitant vasculitis patients were significantly more concerned about almost every aspect of available COVID-19 vaccines [e.g., safety (p < 0.001), components (p < 0.001)], and feared that they could contract SARS-CoV-2 from a vaccine (p < 0.001). These vaccine-hesitant patients were also significantly less pleased with the government's pandemic response, less confident in healthcare team-provided information (p < 0.001), and more likely to report that healthcare providers had no role in their COVID-19 vaccine decision-making (p < 0.001).

Conclusion

Vaccine-hesitant vasculitis patients may have multiple considerations influencing COVID-19 vaccine hesitancy, including vaccine and disease-specific concerns, along with unfavorable perceptions of the healthcare system (government and healthcare providers). Healthcare providers can address some of these concerns by initiating patient-centered discussions around immunizations to help support educated decision-making.

Understanding Stakeholders' Perspectives to Increase COVID-19 Vaccine and Booster Uptake Among Black Individuals With Rheumatic Conditions

OBJECTIVE

Disparities in COVID-19 vaccine and booster uptake persist. This study aimed to obtain perspectives from community and physician stakeholders on COVID-19 vaccine and booster hesitancy and strategies to promote vaccine uptake among Black individuals with rheumatic and musculoskeletal conditions.

METHODS

We invited community leaders and physicians in greater Boston and Chicago to participate in semi-structured interviews using a moderator guide developed a priori. Participants were queried about how to best address vaccine hesitancy, strategies to target high-risk populations, and factors to identify future community leaders. Interviews were audio recorded, transcribed verbatim, and analyzed thematically using Dedoose.

RESULTS

A total of 8 physicians and 12 community leaders participated in this study between November 2021 and October 2022. Qualitative analyses revealed misinformation/mixed messaging and mistrust, with subthemes including conspiracy theories, concerns regarding vaccine development and function, racism and historical injustices, and general mistrust of health care systems as the top cited reasons for COVID-19 vaccine hesitancy. Participants also shared demographic-specific differences, such as race, ethnicity, age, and gender that influenced the identified themes, with emphasis on COVID-19 vaccine access and apathy. Strategies for community-based vaccine-related information dissemination included personal storytelling with an iterative and empathetic approach, while recognizing the importance of protecting community leader well-being.

CONCLUSION

To increase vaccine uptake among Black individuals with rheumatic conditions, strategies should acknowledge and respond to racial/ethnic and socioeconomic injustices that engender vaccine hesitancy. Messaging should be compassionate, individually tailored, and recognize heterogeneity in experiences and opinions. Results from these analyses will inform a planned community-based intervention in Boston and Chicago.

Necrotizing pancreatitis, microangiopathic hemolytic anemia and thrombocytopenia following the second dose of Pfizer/BioNTech COVID-19 mRNA vaccine

Implementing vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a major asset in slowing down the coronavirus disease 2019 (COVID-19) pandemic. For mRNA vaccines, the main severe adverse events reported in pharmacovigilance systems and post-authorization studies were anaphylaxis and myocarditis. Pancreatitis after Pfizer/BioNTech COVID-19 vaccination has been reported only in 10 patients.We report a 31-year-old female with a history of borderline personality disorder, intravenous drug abuse, allergic asthma, eating disorder, psoriatic arthritis treated with tofacitinib, neurogenic bladder disturbance, cholecystectomy, recurrent thoracic herpes zoster, vaginal candida infections and urinary tract infections, who developed pancreatitis associated with thrombotic microangiopathy and hemolytic-uremic syndrome 10 days after the second vaccination, whereas the first has been well tolerated. She was treated by plasma exchange, and eventually by transgastric drainage with implantation of a plastic stent to remove fluid abdominal retentions. She was discharged after 19 days. Since then her condition has improved continuously. Computed tomography after 12 months did not reveal retentions anymore.As other causes of pancreatitis have been excluded, this case of acute pancreatitis, microangiopathic hemolytic anemia and thrombocytopenia, temporally associated with the Pfizer-BioNTech COVID-19 vaccine, suggests a causal link.

Clinical scenarios-based guide for tofacitinib in rheumatoid arthritis

Tofacitinib was the first Janus kinase inhibitor to be approved for the treatment of rheumatoid arthritis (RA), and there is a large body of data to inform the efficacy and safety of this drug for patients at different places in their treatment journeys and with diverse demographics and characteristics. Here, we summarize tofacitinib clinical efficacy and safety data from some clinical trials, post hoc analyses, and real-world studies, which provide evidence of the efficacy of tofacitinib in treating patients with RA at various stages of their treatment journeys, and with differentiating baseline characteristics, such as age, gender, race, and body mass index. In addition, we review the safety data available from different patient subpopulations in the tofacitinib clinical development program, real-world data, and findings from the ORAL Surveillance post-marketing safety study that included patients aged ⩾50 years with pre-existing cardiovascular risk factors. The available efficacy and safety data in these subpopulations can enable better discussions between clinicians and patients to guide informed decision-making and individualized patient care.

Outcomes in children with rheumatic diseases following COVID-19 vaccination and infection: data from a large two-center cohort study in Thailand

Introduction

Vaccination against coronavirus disease 2019 (COVID-19) is effective in protecting patients from severe COVID-19 infection. Disease flare-up following immunization in children with rheumatic disorders may result in patient reluctance to receive the vaccine. Underlying rheumatic diseases or the use of immunosuppressive drugs may influence the outcomes of COVID-19 vaccination and infection. We aimed to describe outcomes in children with rheumatic diseases following COVID-19 immunization and infection.

Methods

This retrospective study was performed at two large academic centers in Thailand. During the COVID-19 pandemic, all patients were routinely queried about COVID-19-related conditions. We included patients with rheumatic diseases aged <18 years who received at least one dose of a COVID-19 vaccine or had a history of COVID-19 infection with more than 6 months of recorded follow-up after the last vaccine dose or COVID-19 illness. Demographic information and data on clinical symptoms, disease activity, treatment, outcomes, and COVID-19 vaccination and infection were collected.

Results

A total of 479 patients were included. Most (229; 47.81%) patients had juvenile idiopathic arthritis, followed by connective tissue diseases (189; 39.46%), vasculitis syndromes (42; 8.76%), and other rheumatic diseases (19; 3.97%). Approximately 90% of patients received at least one dose of COVID-19 vaccination, and half of the patients had COVID-19 infection. Among patients, 10.72% and 3.27% developed a flare after COVID-19 vaccination and COVID-19 illness, respectively. Flare severity after COVID immunization and infection was mainly mild to moderate. The predictor of flare after COVID-19 vaccination was the use of prednisolone ≥10 mg/day before vaccination (hazard ratio: 2.04, 95% confidence interval: 1.05-3.97, p = 0.037). Inactive disease before receiving the COVID-19 vaccination was a predictor of inactive status after a flare (hazard ratio: 2.95, 95% confidence interval: 1.04-8.40; p = 0.043). Overall, 3.36% and 1.61% of patients experienced a new onset of rheumatic disease after receiving the COVID-19 vaccine and after COVID-19 infection, respectively.

Conclusion

The COVID-19 vaccine is recommended for children with rheumatic disease, particularly those who are in stable condition. After COVID-19 vaccination, patients-especially those with active disease before vaccination or those receiving concurrent prednisolone doses of ≥10 mg/day-should be closely monitored.

Management of Patients with Systemic Sclerosis-Associated Interstitial Lung Disease: A Focus on the Role of the Pharmacist

Interstitial lung disease (ILD) is a common manifestation of systemic sclerosis (SSc), which becomes fibrosing and progressive in some patients. Regular monitoring of patients with SSc-ILD is important to assess progression and inform treatment decisions. Therapy for SSc-ILD may include immunomodulatory and antifibrotic therapies. Therapeutic decisions should be made on a case-by-case basis, ideally following multidisciplinary discussion. Most patients with SSc-ILD have several organ manifestations of SSc or comorbidities and are taking a complex medication regimen. Patients with SSc are particularly susceptible to gastrointestinal side-effects of medications due to the gastrointestinal manifestations of the disease. Pharmacists play an important role in the management of patients with SSc-ILD by assisting patients with access to medications, optimizing medication regimens, and advising on alternative dosage forms. Pharmacists can also contribute to patient education to help patients better understand their treatment and how to prevent and manage potential side effects.

Humoral and cellular immune responses in persons with rheumatoid arthritis after a third dose of mRNA COVID-19 vaccine

OBJECTIVE

Disease-modifying anti-rheumatic drugs (DMARDs) that treat rheumatoid arthritis (RA) may reduce immune responses to COVID-19 vaccination. We compared humoral and cell-mediated immunity before and after a 3rd dose of mRNA COVID vaccine in RA subjects.

METHODS

RA patients that received 2 doses of mRNA vaccine enrolled in an observational study in 2021 before receiving a 3rd dose. Subjects self-reported holding or continuing DMARDs. Blood samples were collected pre- and 4 weeks after the 3rd dose. 50 healthy controls provided blood samples. Humoral response was measured with in-house ELISA assays for anti-Spike IgG (anti-S) and anti-receptor binding domain IgG (anti-RBD). T cell activation was measured after stimulation with SARS-CoV-2 peptide. Spearman's correlations assessed the relationship between anti-S, anti-RBD, and frequencies of activated T cells.

RESULTS

Among 60 subjects, mean age was 63 years and 88% were female. 57% of subjects held at least 1 DMARD around the 3rd dose. 43% (anti-S) and 62% (anti-RBD) had a normal humoral response at week 4, defined as ELISA within 1 standard deviation of the healthy control mean. No differences in antibody levels were observed based on holding DMARDs. Median frequency of activated CD4 T cells was significantly greater post- vs. pre-3rd dose. Changes in antibody levels did not correlate with change in frequency of activated CD4 T cells.

CONCLUSION

Virus-specific IgG levels significantly increased in RA subjects using DMARDs after completing the primary vaccine series, though fewer than two-thirds achieved a humoral response like healthy controls. Humoral and cellular changes were not correlated.

Short- and mid-term outcomes in systemic lupus erythematosus patients presenting with disease exacerbation after SARS-CoV-2 mRNA vaccination: A cohort study from Puerto Rico

OBJECTIVE

To determine if SARS-CoV-2 mRNA vaccination has an impact on the clinical course of systemic lupus erythematosus (SLE).

METHODS

Puerto Ricans with SLE who received mRNA COVID-19 vaccines were studied. Demographic parameters, clinical manifestations, disease activity (per Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), disease damage (per Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), emergency room visits, hospitalizations, and pharmacologic therapy were determined. Baseline variables (prior to vaccination) were compared between patients with and without exacerbation after SARS-CoV-2 vaccination. Among those with exacerbation, clinical outcomes were determined up to 1 year after vaccination.

RESULTS

Of the entire cohort (n = 247), 14 (5.7%) had post-vaccination exacerbations. Photosensitivity, oral ulcers, anti-Ro antibodies, higher SLEDAI score, and corticosteroids exposure were associated with post-vaccination flares. Among those with post-vaccination flares, 10 (71.4%) had major organ involvement. No significant differences were observed for mean SLEDAI scores, emergency room visits, hospitalizations, disease damage, and exposure to immunosuppressive drugs before and after SARS-CoV-2 mRNA vaccination. At 12 months of follow-up, all patients were fully controlled without evidence of active disease.

CONCLUSION

In our group of SLE patients, 5.7% had a disease flare after SARS-CoV-2 mRNA vaccination. Most had exacerbations involving major organs/systems. Mucocutaneous manifestations, anti-Ro antibodies, disease activity, and corticosteroids were associated with flares. Awareness of these factors and the possibility of a major lupus flare after vaccination with COVD-19 vaccines is critical to provide timely and effective therapy.

B Cell Reconstitution is Associated With COVID-19 Booster Vaccine Responsiveness in Patients Previously Seronegative Treated With Rituximab

OBJECTIVE

To assess factors associated with serologic response to the coronavirus 2019 (COVID-19) booster vaccine in patients with autoimmune rheumatic diseases treated with rituximab (RTX) who were previously serologically unresponsive to the initial vaccine series.

METHODS

A retrospective chart review of patients treated with RTX who failed to demonstrate a serologic response to the first SARS-CoV-2 vaccination series and subsequently received an mRNA vaccine booster was performed. Serologic response ≥ 4 weeks after the booster was the primary outcome. Fisher exact tests, t tests, and Wilcoxon rank-sum tests were used for comparisons.

RESULTS

In 31 patients who were previously seronegative, 68% seroconverted following a booster of the COVID-19 vaccine. B cell reconstitution was significantly different between those with positive (median 1.79, IQR 0.65-3.00) and negative (median 0, IQR 0-0) serologic responses to the booster. The days from last RTX dose were also statistically different among seroconverters (median 301, IQR 251-368) vs nonseroconverters (median 188, IQR 169-245). Demographic characteristics were not associated with serologic positivity. Positive predictive value of B cell presence was 90.9% (95% CI 70.8-98.9) and negative predictive value was 100% (95% CI 59-100) for serologic response to the mRNA booster vaccine. Positive predictive value of time ≥ 6 months from last RTX dose to booster was 78.3% (95% CI 56.3-92.5) and the negative predictive value was 62.5% (95% CI 24.5-91.5).

CONCLUSION

Detectable B cells and longer time from last RTX exposure were associated with the development of anti-SARS-CoV-2 spike protein antibodies following the booster vaccine. These findings should be considered in timing boosters in patients treated with RTX.

Humoral response to mRNA-based COVID-19 vaccine in patients with immune thrombocytopenia

Data for COVID-19 vaccine response in patients with immune thrombocytopenia (ITP) are very limited. In a study of 28 patients with ITP, anti-severe acute respiratory syndrome coronavirus 2 spike antibody titres were measured after vaccination. The seroconversion rate for ITP patients was 91.3%, comparable to that in healthy controls (HCs). However, the antibody titre in ITP patients was significantly lower than that in HCs and declined with ageing. Furthermore, the antibody titre in ITP patients who received a minimum prednisolone dose of at least 5 mg/day at any time-point at or after initial vaccination was lower than that in other patients.

Axial spondyloarthritis and COVID-19: course, interactions, outcomes, and the role of vaccination

The review analyzes data on the course and outcomes of axial spondyloarthritis (axSpA) accumulated over the previous 2.5 years of the COVID-19 pandemic. The issues of clinical and immunological efficacy of vaccination against COVID-19 in this disease are considered. It was noted that the presence of axSpA, as well as treatment with tumor necrosis factor-á inhibitors and non-steroidal anti-inflammatory drugs, did not significantly increase the risk of COVID-19 infection and did not worsen its outcomes, apart from an increase in the incidence of venous thromboembolism. At the same time, it is assumed that anticytokine therapy for SpA may protect against severe COVID-19 course.The data presented suggest that the benefits of vaccination in SpA far outweigh the potential harms associated with the development of adverse events. It has been shown that in patients with SpA, vaccination does not affect the activity of the inflammatory process, and biologic disease modifying antirheumatic drugs have almost no significant effect on the post-vaccination response.

Post-mRNA vaccine flares in autoimmune inflammatory rheumatic diseases: Results from the COronavirus National Vaccine registry for ImmuNe diseases SINGapore (CONVIN-SING)

BACKGROUND

Studies of flares of autoimmune inflammatory rheumatic diseases (AIIRD) after COVID-19 mRNA vaccination are limited by small sample size, short follow up or at risk of selection bias.

METHODS

A national retrospective cohort study of consecutive AIIRD patients ≥12 years old, across 8 hospitals who received at least one dose of a COVID-19 mRNA vaccine. Patients were included from the date of 1st vaccine dose and censored at the time of flare or on the date of the clinic visit at least 3 months from cohort entry, whichever came first. Predictors of flare were determined by Cox proportional hazards analysis.

FINDINGS

4627 patients (73% Chinese, 71% female) of median (IQR) age 61 (48, 70) years were included; 42% Rheumatoid arthritis, 14% Systemic lupus erythematosus and 11% Psoriatic arthritis. 47% were in remission, 41% low disease activity, 10% moderate disease activity and 1% in high disease activity. 18% patients flared, of which 11.7% were within the 3-month period of interest. 11.8% patients improved. Median (IQR) time-to-flare was 60 (30, 114) days. 25% flares were self-limiting, 61% mild-moderate and 14% severe. Older patients (53-65 years and >66 years) had a lower risk of flare [HR 0.6 (95% CI 0.5-0.8) and 0.7 (0.6-0.8) respectively]. Patients with inflammatory arthritis and with active disease had a higher risk of flare [HR 1.5 (1.2-2.0) and 1.4 (1.2-1.6), respectively]. Treatment with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), immunosuppression and prednisolone was also associated with an increased risk of flare [HR 1.5 (1.1-2), 1.2 (1.1-1.4) and 1.5 (1.2-1.8) for prednisolone ≤7.5 mg respectively].

INTERPRETATION

There was a moderately high rate of AIIRD flares after mRNA vaccination but also improvement in several patients. Severe flares and hospitalisation were rare. Thus, vaccination remains safe and highly recommended.

Impact of BNT162b2 mRNA anti-SARS-CoV-2 vaccine on interferon-alpha production by plasmacytoid dendritic cells and autoreactive T cells in patients with systemic lupus erythematosus: The COVALUS project

OBJECTIVE

To evaluate the specific response of SLE patients to BNT162b2 vaccination and its impact on autoimmunity defined as in vivo production of interferon-alpha (IFNα) by plasmacytoid dendritic cells (pDCs) and autoreactive immune responses.

METHODS

Our prospective study included SLE patients and healthy volunteers (HV) who received 2 doses of BNT162b2 vaccine 4 weeks apart. Subjects under immunosuppressive drugs or with evidence of prior COVID-19 were excluded. IgG anti-Spike SARS-CoV-2 (anti-S) antibodies, anti-S specific-B cells, anti-S specific T cells, in vivo INF-α production by pDCs, activation marker expression by pDCs and autoreactive anti-nuclear T cells were quantified before first injection, before second injection, and 3 and 6 months after first injection.

RESULTS

Vaccinated SLE patients produced significantly lower IgG antibodies and specific B cells against SARS-CoV-2 as compared to HV. In contrast, anti-S T cell response did not significantly differ between SLE patients and HV. Following vaccination, the surface expression of HLA-DR and CD86 and the in vivo production of IFNα by pDCs significantly increased in SLE patients. The boosted expression of HLA-DR on pDCs induced by BNT162b2 vaccine correlated with the overall immune responses against SARS-CoV-2 (anti-S antibodies: r = 0.27 [0.05-0.46], p = 0.02; anti-S B cells: r = 0.19 [-0.03-0.39], p = 0.09); anti-S T cells: r = 0.28 [0.05-0.47], p = 0.016). Eventually, anti-SARS-CoV-2 vaccination was associated with an overall decrease of autoreactive T cells (slope = - 0.00067, p = 0.015).

CONCLUSION

BNT162b2 vaccine induces a transient in vivo activation of pDCs in SLE that contributes to the immune responses against SARS-CoV-2. Unexpectedly BNT162b2 vaccine also dampens the pool of circulating autoreactive T cells, suggesting that vaccination may have a beneficial impact on SLE disease.

COVID-19 severity and vaccine breakthrough infections in idiopathic inflammatory myopathies, other systemic autoimmune and inflammatory diseases, and healthy controls: a multicenter cross-sectional study from the COVID-19 Vaccination in Autoimmune Diseases (COVAD) survey

OBJECTIVES

We aimed to compare the spectrum and severity of COVID-19 and vaccine breakthrough infections (BIs) among patients with IIMs, other systemic autoimmune and inflammatory diseases (SAIDs), and healthy controls (HCs).

METHODS

This is a cross-sectional study with data from the COVAD study, a self-reported online global survey that collected demographics, COVID-19 history, and vaccination details from April to September 2021. Adult patients with at least one COVID-19 vaccine dose were included. BIs were defined as infections occurring > 2 weeks after any dose of vaccine. Characteristics associated with BI were analyzed with a multivariate regression analysis.

RESULTS

Among 10,900 respondents [42 (30-55) years, 74%-females, 45%-Caucasians] HCs were (47%), SAIDs (42%) and IIMs (11%). Patients with IIMs reported fewer COVID-19 cases before vaccination (6.2%-IIM vs 10.5%-SAIDs vs 14.6%-HC; OR = 0.6, 95% CI 0.4-0.8, and OR = 0.3, 95% CI 0.2-0.5, respectively). BIs were uncommon (1.4%-IIM; 1.9%-SAIDs; 3.2%-HC) and occurred in 17 IIM patients, 13 of whom were on immunosuppressants, and 3(18%) required hospitalization. All-cause hospitalization was higher in patients with IIM compared to HCs [23 (30%) vs 59 (8%), OR = 2.5, 95% CI 1.2-5.1 before vaccination, and 3 (18%) vs 9 (5%), OR = 2.6, 95% CI 1.3-5.3 in BI]. In a multivariate regression analysis, age 30-60 years was associated with a lower odds of BI (OR = 0.7, 95% CI 0.5-1.0), while the use of immunosuppressants had a higher odds of BI (OR = 1.6, 95% CI 1.1-2.7).

CONCLUSIONS

Patients with IIMs reported fewer COVID-19 cases than HCs and other SAIDs, but had higher odds of all-cause hospitalization from COVID-19 than HCs. BIs were associated with the use of immunosuppressants and were uncommon in IIMs.

Appraising SARS-CoV-2 infections after full mRNA COVID-19 vaccination in patients with systemic lupus erythematosus (SLE)

The 2019 Coronavirus disease (COVID-19) vaccine is a major weapon in the fight against the severe acute respiratory syndrome brought about by coronavirus 2 (SARS-CoV-2). The vaccine significantly reduces the risk and severity of infection by SARS-CoV-2. Patients with systemic lupus erythematosus (SLE) need protection from vaccine-preventable diseases including COVID-19. SLE patients have higher rates of severe infections due to immunosuppressive therapies and multiple immunologic defects - both of which are capable of blunting the immune responses after vaccination. In the management of COVID-19, recommendations have been developed to guide adjustments and/or continuation of immunosuppressive therapies for an effective immune response following vaccination with mRNA-based or viral vector-delivered vaccines. Monoclonal antibodies have also become available since December 2021. Here we present three cases of SLE patients who contracted COVID-19 after vaccination. One was managed in ambulatory settings and two required inpatient hospital admission.

Understanding the Attitudes and Willingness of Adult Chinese Patients with Rheumatic Diseases Towards COVID-19 Vaccination

BACKGROUND

The SARS-CoV-2 pandemic has imposed substantial health and economic burdens on the societies. COVID-19 vaccination is the most effective method of controlling the epidemic. This study assessed the attitude, willingness, and related factors of adult patients with rheumatic diseases (RDs) in China towards COVID-19 vaccination and identified their reasons for being vaccinated.

METHODS

 A cross-sectional survey was administered to patients with rheumatic diseases from July 18 to August 18, 2021, using an online questionnaire. Logistic regression analysis was performed to examine the data.

RESULTS

We analyzed data drawn from 464 participants who provided valid responses. A total of 324 (69.83%) RD patients were not willing to be vaccinated, of which 76.97% believed that COVID-19 vaccination might exacerbate the diseases symptoms. Logistic regression analysis showed that a combination of experiencing systemic damage, being in the acute attack stage of the disease, and fear of the adverse impact of vaccination on rheumatism, etc., were the predominant factors affecting the intentional vaccination rate in adult patients with rheumatic diseases (p < 0.05).

CONCLUSION

The COVID-19 intentional vaccination rate was relatively low in adult Chinese patients with RD. Public health education and the dissemination of government scientific data for patients with RD should be enhanced to increase COVID-19 vaccination rates.

Safety of the BNT162b2 mRNA COVID-19 vaccine in children and adolescents with juvenile idiopathic arthritis: a tertiary-center early experience

Background

Research on the COVID-19 vaccination in patients with underlying rheumatic disorders in pediatric age is lacking. We studied possible adverse events of the mRNA BNT162b2 vaccine against SARS-CoV-2 (Pfizer-BioNTech) in children and adolescents with juvenile idiopathic arthritis (JIA), and also if there is a risk of flaring of the underlying JIA. We reported 36 JIA patients aged 5–18 years old received 2 doses of the COVID-19 vaccine (72 doses). Patients were followed before and after vaccination, and any related adverse event was recorded. JIA disease activity was assessed using Juvenile Arthritis Disease Activity Score-10 (JADAS-10) before and after vaccination.

Results

Among 72 doses of the vaccine received, local adverse events (AEs) were reported by majority of the patients (66.7%); most commonly reported local AE was pain at the site of injection. Systemic AEs were revealed by (65.3%), most commonly reported systemic AEs were tiredness, myalgia, and headache. Almost all the reported AE were mild to moderate and resolved within 1–2 days and were also more frequently noted after the second dose. No flaring of the underlying primary rheumatic disease after vaccination. No one of the study group revealed serious adverse events.

Conclusions

This is one of the early studies reporting that mRNA COVID-19 vaccine seems to be safe in children and adolescents with JIA. Almost all the reported adverse events were mild to moderate and transient. Also, no serious adverse events or flaring of the primary disease were reported.

Rheumatic disease patient decision-making about COVID-19 vaccination: a qualitative analysis

BACKGROUND

Although patients with rheumatic and musculoskeletal diseases (RMDs) are at increased risk for adverse outcomes of COVID-19 illness compared to healthy controls, they also have lower rates of willingness to be vaccinated. Previous research has identified reasons for vaccine hesitancy among patients with RMDs (such as concerns about side effects and flares), but little is known about what these reasons mean in the context of patients' lives, or how vaccine decision making is experienced from a patient perspective. Our objective was to describe decision-making about COVID-19 vaccination among RMD patients.

METHODS

Participants in a RMD registry were invited to complete monthly online surveys regarding COVID-19 vaccination from March-June 2021. We qualitatively analyzed comments from two open-ended survey questions reporting general experiences with vaccination and side effects. Comments were coded for attitudes towards COVID-19 vaccination, vaccine access, rheumatologic medication management around vaccination, and vaccine side effects. Themes were identified for the process and context of COVID-19 vaccine decisions, patient motivations for receiving or avoiding vaccination, and consistency of peri-vaccine medication management with current ACR guidelines.

RESULTS

We analyzed 710 comments from 537 respondents. Commenting respondents had a mean age of 64 years, were 87% female, 94% white, and 93% received/intended to receive ≥ 1 dose of a COVID-19 vaccine. Desire for protection and a return to normal routines motivated some commenters to get vaccinated, while concerns about vaccine side effects motivated others to delay or avoid vaccination. Several commenters reported disease flares following vaccination. Some commenters did not consult their providers about vaccination and failed to withhold immunomodulatory medications during vaccination, while others withheld medications more conservatively than recommended by current ACR guidelines, either on their own or directed by their provider.

CONCLUSIONS

While most commenters were vaccine-accepting, challenges to COVID-19 vaccine uptake in the RMD population may include fears of side effects, including worsened RMD symptoms, and perceptions that vaccination is unnecessary. Addressing these concerns and beliefs may be critical for promoting vaccination in this population.

New-onset inflammatory arthritis after COVID-19 vaccination: A systematic review

AIM

To analyze the clinical patterns of new-onset inflammatory arthritis after COVID-19 vaccination among patients without pre-existing rheumatic or autoimmune diseases.

METHOD

Case reports and series of new-onset inflammatory arthritis after COVID-19 vaccination were collected before April 2022. Clinical characteristics including diagnosis, age, gender, vaccine types, time interval between events, joint involvement (poly- or oligo-/monoarthritis), and laboratory data reflecting inflammatory status were sorted and P values between these parameters are calculated with independent sample Student's t test or 2 × 2 Fisher's exact test.

RESULTS

Among 39 cases with new-onset post-vaccination arthritis including 25 females and 13 males (1 unknown), the most common diagnosis is adult-onset Still's disease (AoSD, 10 cases), and the most common vaccine types are BNT162b2 (16 cases) and AZD-1222 (or ChAdOx1-nCoV19, 15 cases). Sub-analysis reveals that post-vaccination polyarthritis is more common among females (P = .016, by 2 × 2 Fisher's exact test, compared with male patients) and older patients (P = .006, by Student's t test). The C-reactive protein level is significantly higher in cases with post-vaccination inflammatory polyarthritis than oligoarthritis (P = .029), as well as in cases with AoSD than other causes of post-vaccination arthritis (P = .004). However, serum level of erythrocyte sedimentation rate in patients with post-vaccination AoSD are independent of other clinical variables in the analysis.

CONCLUSION

New-onset post-vaccination polyarthritis are more common in females and older patients. Although COVID-19 vaccines may lead to inflammatory arthritis, the benefits of vaccination substantially outweigh the potential risks of such serious adverse effects due to their rarity.

Postvaccination anti-S IgG levels predict anti-SARS-CoV-2 neutralising activity over 24 weeks in patients with RA

OBJECTIVES

To correlate immune responses following a two-dose regimen of mRNA anti-SARS-CoV-2 vaccines in patients with rheumatoid arthritis (RA) to the development of a potent neutralising antiviral activity.

METHODS

The RECOVER study was a prospective, monocentric study including patients with RA and healthy controls (HCs). Assessments were performed before, and 3, 6, 12 and 24 weeks, after the first vaccine dose, respectively, and included IgG, IgA and IgM responses (against receptor binding domain, S1, S2, N), IFN-γ ELISpots as well as neutralisation assays.

RESULTS

In patients with RA, IgG responses developed slower with lower peak titres compared with HC. Potent neutralising activity assessed by a SARS-CoV-2 pseudovirus neutralisation assay after 12 weeks was observed in all 21 HCs, and in 60.3% of 73 patients with RA. A significant correlation between peak anti-S IgG levels 2 weeks after the second vaccine dose and potent neutralising activity against SARS-CoV-2 was observed at weeks 12 and 24. The analysis of IgG, IgA and IgM isotype responses to different viral proteins demonstrated a delay in IgG but not in IgA and IgM responses. T cell responses were comparable in HC and patients with RA but declined earlier in patients with RA.

CONCLUSION

In patients with RA, vaccine-induced IgG antibody levels were diminished, while IgA and IgM responses persisted, indicating a delayed isotype switch. Anti-S IgG levels 2 weeks after the second vaccine dose correlate with the development of a potent neutralising activity after 12 and 24 weeks and may allow to identify patients who might benefit from additional vaccine doses or prophylactic regimen.

Immunogenicity of inactivated COVID-19 vaccine in patients with autoimmune inflammatory rheumatic diseases

Progress has been made in COVID-19 vaccine development, with encouraging safety and efficacy data. The purpose of this study was to investigate the immunogenicity of inactivated COVID-19 vaccine in patients with autoimmune inflammatory rheumatic diseases (AIIRD). Patients with AIIRD (n = 101) were included in this study. All patients received 2 doses of inactivated COVID-19 vaccine. Serum anti-S1/RBD protein IgG was detected 2-16 weeks after the second vaccination. Seropositivity was defined as IgG ≥ 1.00 bound antibody unit S/CO. Immunogenicity of inactivated COVID-19 vaccine was assessed by seropositivity rate and the levels of serum IgG antibody against anti-S1/RBD protein, compared with the general population (n = 46). There was no difference by statistical significance in the seropositivity rate between patients with AIIRD (82.2%) and SLE (86.1%) and the control group (93.5%), p > 0.05. The level of anti-S1/RBD protein IgG antibodies in patients with AIIRD (median [IQR], 8.8 [2.2-17.3]) and SLE (median [IQR], 9.6 [2.4-20.4]) was comparable to that in the control group (median [IQR], 7.2 [3.1-14.2]), p > 0.05. Patients treated with glucocorticoids(GCs) (median dose, [IQR]: 2.5 mg/day [IQR 2.5-5.0]) or hydroxychloroquine(HCQ) or GCs + HCQ without other immunomodulatory medications, had an appropriate immunogenic response(88.1%) with high levels of anti-S1/RBD protein IgG(median [IQR], 12.1 [6.5-20.4]). Neither of patients treated with rituximab had positive serum antibodies, which was statistically significant, compared with the control group (p < 0.01). Compared with the control group, methotrexate(MTX) and iguratimod(IGU) was significantly reduced the level of anti-S1/RBD protein IgG antibodies. Inactivated COVID-19 vaccine had appropriate immunogenicity in patients with AIIRD. Immunogenicity of inactivated COVID-19 vaccine was severely impaired by rituximab, and also suppressed by MTX and IGU, while low doses of GC and HCQ had negligible effect.

Humoral immune response against BNT162b2 mRNA COVID-19 vaccine in patients with rheumatic disease undergoing immunosuppressive therapy: A Japanese monocentric study

We investigated serum total antibody titers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein receptor-binding domain after BNT162b2 mRNA vaccination against coronavirus disease 2019 (COVID-19) in Japanese patients taking various immunosuppressive medications for rheumatic disease. In 212 outpatients with rheumatic diseases at Kagawa University Hospital and 43 healthy volunteers (controls), all of whom had received 2 doses of BNT162b2 vaccine, serum antibody titers of SARS-CoV-2 spike protein were analyzed at least 14 days after the second dose. Many of the patients were taking immunosuppressive agents to manage their rheumatic disease. The antibody titers against SARS-CoV-2 spike protein in these patients were significantly lower than those in controls. The analysis of therapeutic agents revealed that the antibody titers in patients treated with rituximab were much lower than those in controls. In patients treated with tacrolimus, baricitinib, azathioprine, mycophenolate mofetil, abatacept, tumor necrosis factor inhibitors, cyclosporine, interleukin-6 inhibitors, methotrexate, or glucocorticoids, antibody titers were moderately lower than those of controls. Interleukin-17 and interleukin-23 inhibitors did not impair the humoral response. In addition, the combination of methotrexate with various immunosuppressive agents reduced titers, although not significantly. In Japanese patients with rheumatic disease, many immunosuppressants impaired the immune response to the BNT162b2 vaccine. The degree of decline in antibody titers differed according to immunosuppressant. When used concomitantly with other immunosuppressants, methotrexate may impair the immune response to the BNT162b2 vaccine. However, immunomodulatory treatments such as interleukin-17 and -23 inhibitors may not attenuate this response in patients with rheumatic disease.

COVID-19 outcomes in giant cell arteritis and polymyalgia rheumatica versus rheumatoid arthritis: A national, multicenter, cohort study

Objectives

To determine whether giant cell arteritis and polymyalgia rheumatica (GCA/PMR) represent independent risk factors for worse outcomes in COVID-19.

Methods

Observational, national, French, multicenter cohort (NCT04353609) comprising patients aged ≥18 years with confirmed diagnoses of either GCA, PMR or rheumatoid arthritis (RA) having presented COVID-19; those under rituximab were excluded. Primary endpoint was COVID-19 severity in GCA/PMR patients as compared to RA. We also aimed to describe the evolution of GCA/PMR patients following COVID-19. Multinomial logistic regression models were performed, with and without adjustment on pre-specified confounding factors (i.e., age, sex, body mass index, arterial hypertension, diabetes and cardiovascular disease). Unadjusted and adjusted multinomial odds-ratio (OR/aOR) and their 95% confidence intervals (CIs) were calculated as effect size using RA as reference group.

Results

Between April 15, 2020, and August 20, 2021, 674 patients [45 (6.6%) GCA, 47 (7.0%) PMR, 582 (86.4%) RA; 62.8 years, 73.2% female] were included. Compared to RA patients, those with GCA/PMR were older and more frequently presented hypertension, diabetes and cardiovascular disease. Severe COVID-19 and death occurred in 24 (26.1%) and 16 (17.8%) patients with GCA/PMR, respectively. Unadjusted analyses revealed higher odds of severe COVID-19 [OR = 3.32 (95% CI 1.89–5.83; p < 0.001)] and death [OR = 3.20 (95%CI 1.67–6.13; p < 0.001)] for GCA/PMR compared to RA. After model adjustment, these odds were attenuated.

Conclusion

Patients with GCA/PMR were more likely to have severe COVID-19 and higher mortality compared to those with RA. This worse prognosis is mostly due to well known risk factors for the general population rather than vasculitis per se.

COVID-19 and rheumatic diseases: A mini-review

Joint pain and arthralgia can be manifestations of COVID-19, and studies evaluating long COVID symptoms identified the persistence of these disorders. Moreover, some case reports highlighted the development of new inflammatory arthritis in patients with COVID-19, suggesting a possible relation. Viral infections and rheumatic diseases share a documented relationship; they have been associated with genetic and environmental risk factors responsible for some of them. There is crosstalk between viruses and the immune system during the development of several rheumatic diseases. Moreover, infections may participate in the pathogenesis of autoimmune rheumatic diseases and contribute to patient mortality. Therefore, it is crucial to provide a clearer insight into the interaction between viral infections and rheumatic diseases. Here, we provide a mini-review of the current literature with the aim of shedding light on the relationship between COVID-19 and rheumatic or musculoskeletal diseases, which is still unclear. Specifically, we examined several aspects: risk for the rheumatic population of acquiring the virus or developing severe symptoms, similarities of COVID-19 and arthritis, the possible rheumatic consequence of COVID-19, of rheumatic drugs and vaccines, and COVID-19 prevention in rheumatic patients through vaccination.

Single-center experience of COVID-19 vaccine in patients with inflammatory rheumatic disease: Real-life data

Background/Aim: Patients with rheumatic disease are at high risk of infection complications, and vaccines are essential to prevent these diseases. Moreover, biologic disease-modifying/targeted synthetic anti-rheumatic drugs (b/tsDMARDs) have been shown to reduce the immunogenicity of vaccines, although their effectiveness, side effects, and effects on disease activity are not yet clear. In this study, we aimed to investigate the incidence of post-vaccine side effects, disease exacerbation, and COVID-19 infection despite vaccination in patients with inflammatory rheumatic disease; the difference in vaccination effects between patients who received and did not receive b/tsDMARD treatments. Methods: Patients received b/tsDMARD (i.e., biologic group (BG)) (n = 194) who were admitted to the rheumatology outpatient clinic, were included in this study. All patients with inflammatory rheumatological disease, who did not receive b/tsDMARD (n = 185), but who applied to the rheumatology outpatient clinic during this time, were included in the non-biologic group (NG). Patients followed were included and evaluated cross-sectionally. Clinical and demographic characteristics, as well as type of COVID-19 vaccination, post-vaccine side effects, COVID-19 infection status before and after vaccination, and post-vaccine rheumatological disease exacerbation, were also evaluated. Results: In BG, 92.2% of patients were vaccinated, but for NG, 82.7% were vaccinated against COVID-19 patients with BG, 46.2% were vaccinated with CoronaVac vaccine alone, 51.4% with Pfizer/BioNTech BNT162b2 vaccine alone, and 37.4% with a combination of CoronaVac and BNT162b2 vaccines. In the NG, 53.8% of patients were vaccinated with CoronaVac vaccine alone, 48.6% with BNT162b2 vaccine alone, and 36.2% with a combination of CoronaVac and BNT162b2 vaccines. There was a significant difference between groups, according to vaccine types (P = 0.040), as this difference was due to a larger number of patients vaccinated with the CoronaVac + BNT162b2 combination for BG. Adverse effects were detected in 99 patients (55.9%) with BG and 95 patients (62.5%) with NG post-vaccination. There was no difference between BG and NG vaccines (CoronaVac, BNT162b2, or their combination) for adverse effects (P > 0.05 for all). The vaccine with the most common adverse events was BNT162b2, for both BG and NG. The most common side effect was arm pain, significantly higher in BG (P = 0.014). Fever and rash were more common for NG (P = 0.017). Disease exacerbation was not observed with BG, whereas it was detected in 5 (1%) patients for NG that was different (P = 0.021). SARS-COV-2 infection was also significantly less common for BG vs. NG (15.3% vs. 20.3%) (P = 0.017). Despite COVID-19 vaccinations, 56 patients with BG and 62 patients with NG had COVID-19 (P = 0.005). Conclusion: Standardized vaccination comparisons could not be achieved, as patients using b/tsDMARD were vaccinated for fewer COVID-19 infections. Additionally, COVID-19 vaccines are well-tolerated in patients with rheumatological disease, with vaccine-related disease activity at 1%, only seen in those not using b/tsDMARDs.

New Onset and Exacerbations of Psoriasis Following COVID-19 Vaccines: A Systematic Review

BACKGROUND

Vaccination has been promoted to control viral transmission in response to the coronavirus disease 2019 (COVID-19) pandemic. Cases of new-onset or exacerbation of psoriasis, an immune-mediated inflammatory disease, were reported following COVID-19 vaccination. However, a comprehensive review examining the association between COVID-19 vaccination and the occurrence or exacerbation of psoriasis has yet to be performed.

OBJECTIVE

The aim of this systematic review is to investigate the demographics, clinical variables, and outcomes associated with psoriasis following COVID-19 vaccination.

METHODS

A systematic literature search was conducted using the PubMed, Embase, Web of Science, and Cochrane databases from database inception to April 25, 2022. The review included studies with relevant terms, including 'psoriasis,' 'psoriasis vulgaris,' 'guttate psoriasis,' 'pustular psoriasis,' 'palmoplantar pustulosis,' 'psoriatic erythroderma,' 'psoriatic arthritis,' 'COVID-19,' and 'vaccine.' We included all studies reporting at least one patient who developed new-onset psoriasis or experienced a psoriasis flare following at least one dose of any COVID-19 vaccine. A flare was defined as the worsening of disease conditions after vaccination according to the study by Gregoire et al. The appraisal tool described by Murad et al. was used to assess the quality of case reports and series, whereas the National Institute of Health quality assessment tool was used to assess observational studies.

RESULTS

The initial search yielded 367 results, including 7 studies reporting new-onset psoriasis, 32 studies reporting psoriasis flares, and 4 studies reporting both. The most commonly observed psoriasis subtype was plaque-type psoriasis. mRNA vaccines, including those produced by Moderna and BioNTech/Pfizer, were frequently associated with subsequent psoriasis episodes. First, second, and third vaccine doses were associated with psoriasis incidents, with the second dose most frequently associated with psoriasis flares. Delayed onset was observed, ranging from 2 to 21 days in the new-onset group and from 1 to 90 days in the flare group. Most patients experienced favorable outcomes, with improvement or resolution occurring within 3 days to 4 months.

CONCLUSIONS

Both new-onset psoriasis and psoriasis flares were reported as cutaneous adverse events following COVID-19 vaccination. Psoriatic patients may require regular follow-up before and after COVID-19 vaccination.

Glucocorticoids' treatment impairs the medium-term immunogenic response to SARS-CoV-2 mRNA vaccines in Systemic Lupus Erythematosus patients

Limited data exists on SARS-CoV-2 sustained-response to vaccine in patients with rheumatic diseases. This study aims to evaluate neutralizing antibodies (nAB) induced by SARS-CoV-2 vaccine after 3 to 6 months from administration in Systemic Lupus Erythematosus (SLE) patients, as a surrogate of sustained-immunological response. This cross-sectional study compared nAB titre of 39 SLE patients and 37 Healthy individuals with no previous SARS-CoV-2 infection, who had all received a complete regimen of a mRNA SARS-CoV-2 vaccine within the last 3 to 6 months. We included four lines of SLE treatment including Not-treated, Hydroxychloroquine, immunosuppressive drugs and biological therapy. Glucocorticoids were allowed in all groups. Healthy and Not-treated individuals showed the highest levels of nAB. Treated patients presented lower nAB titres compared to Healthy: a 73% decrease for First-Line patients, 56% for Second-Line treatment and 72% for Third-Line. A multivariate analysis pointed to Glucocorticoids as the most associated factor with declining nAB levels (75% decrease) in treated SLE. Furthermore, a significant reduction in nAB titres was observed for Rituximab-users compared to Healthy subjects (89% decrease). Medium-term response of SLE patients to SARS-CoV-2 mRNA vaccines is negatively impacted in Glucocorticoids and Rituximab users. These findings might help to inform recommendations in vaccination protocols for SLE patients.

Humoral and cellular immune response to mRNA SARS-CoV-2 BNT162b2 vaccine in adolescents with rheumatic diseases

BACKGROUND

Data about safety and efficacy of the mRNA SARS-CoV-2 vaccine in adolescents with rheumatic diseases (RD) is scarce and whether these patients generate a sufficient immune response to the vaccine remains an outstanding question.

OBJECTIVE

To evaluate safety and humoral and cellular immunity of the BNT162b2 vaccine in adolescents 12 to 18 years with RD and immunosuppressive treatment compared with a healthy control group.

METHODS

Adolescents from 12 to 18 years with RD followed at Hospital La Paz in Madrid (n = 40) receiving the BNT162b2 mRNA vaccination were assessed 3 weeks after complete vaccination. Healthy adolescents served as controls (n = 24). Humoral response was measured by IgG antiSpike antibodies, and cellular response by the quantity of IFN-γ and IL-2 present in whole blood stimulated with SARS-CoV-2 Spike and M proteins.

RESULTS

There were no differences in spike-specific humoral or cellular response between groups (median IFN-γ response to S specific protein; 528.80 pg/ml in controls vs. 398.44 in RD patients, p 0.78, and median IL-2 response in controls: 635.68 pg/ml vs. 497.30 in RD patients, p 0.22. The most frequent diagnosis was juvenile idiopathic arthritis (26/40, 65%) followed by Lupus (6/40, 15%). 60% of cases (23/40) received TNF inhibitors and 35% (14/40) methotrexate. 40% of patients (26/64) had previous SARS-CoV-2 infection, 9 in the control group and 17 in the RD patients without differences. Of note, 70% of infections were asymptomatic. A higher IFN-γ production was found in COVID-19 recovered individuals than in naive subjects in both groups (controls: median 859 pg/ml in recovered patients vs. 450 in naïve p 0.017, and RD patients: 850 in recovered vs. 278 in naïve p 0.024). No serious adverse events or flares were reported following vaccination.

CONCLUSIONS

We conclude that standard of care treatment for adolescents with RD including TNF inhibitors and methotrexate did not affect the humoral and the cellular immunity to BNT162b2 mRNA vaccination compared to a healthy control group. The previous contact with SARS-CoV-2 was the most relevant factor in the immune response.

COVID-19 Outcomes and Vaccination in Patients with Spondyloarthritis

The rapid transmission of the highly infectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), led to widespread infection throughout the world. Concerns and challenges regarding COVID-19 illness have emerged for patients with immune-mediated inflammatory diseases, such as spondyloarthritis (SpA), who receive treatment with biologic or targeted synthetic disease-modifying antirheumatic drugs (DMARDs), because this population is vulnerable to infections and has a high prevalence of risk factors associated with severe COVID-19 illness. Available data on COVID-19 indicate that patients with SpA who are treated with DMARDs have SARS-CoV-2 infection rates comparable with those in the general population, with similar increased risk associated with older age and comorbidities. Novel vaccines against SARS-CoV-2 are approved or authorized for emergency use by the US Food and Drug Administration, and others are in development to prevent infection and serious illness. This review provides an overview of SpA, the mechanism of action for the SARS-CoV-2 infection, the clinical course of COVID-19, and the vaccines approved for, or in development against, SARS-CoV-2. Detailed information on the use of established vaccines in patients with SpA receiving DMARDs is provided, along with recommendations for COVID-19 vaccination. Available evidence has shown COVID-19 vaccination in patients with SpA, among other rheumatic diseases, to be safe and effective with most DMARD use; however, there is evidence of potential interference with some therapies used in SpA. Healthcare providers should educate patients to provide the knowledge and confidence to receive a COVID-19 vaccine, since the potential benefit outweighs the low risk of vaccine-related adverse events.

Safety and immunogenicity of inactivated COVID-19 vaccination in adult rheumatic patients in South China: a prospective study

Patients with rheumatic diseases (RD) are considered to be a high-risk population for infection with the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The effectiveness of inactivated COVID-19 vaccinations (ICVs) was described as more effective than 95%. Despite this, no data on the immunogenicity and safety of the ICV in Han race stable RD patients in China. In this study, we sought to assess the safety and immunogenicity of the ICVs in RD patients in South China. A total of 80 adult stable RD patients were recruited. Following 14–35 days of immunization, cheiluminescence immunoassays (CLIA) were utilized to detect antibodies titers. An investigation into the relative parameters on the immunogenicity response to vaccination was carried out using logistic regression analysis. Compared to the HC group, the positive response of IgG and Nab in RD patients were lower than those in healthy control (HC) (P = .040 and P < .0001, respectively) after two doses of ICV were inoculated. The use of methotrexate (P = .016) and prednisolone (P = .018), and the level of red blood cell distribution width-C (RDW-C) (P = .035) and C-reactive protein (P = .015) were independently associated with lower rises in the magnitude of COVID-19 vaccine antibodies. No vaccine-related serious adverse reactions were observed in either group. After receiving two doses of ICVs, the production of protective antibodies in stable RD patients treated with immunosuppressive agents may decrease. It was discovered that ICVs were safe and well tolerated by RD patients.

What is the context?

There are currently no accessible data on the efficacy and safety of inactivated COVID-19 vaccinations in South China RD patients who are receiving immunosuppressive medications.

What is new?

Inactivated COVID-19 vaccinations were immunogenic in stable RD patients in our investigation. No significant adverse reactions to the vaccination were seen in either group. No disease flares were observed in our study.

What is the impact?

Inactivated COVID-19 vaccinations are immunogenic and safe in stable RD patients in China, according to the findings of this study. The use of methotrexate or prednisolone, the RDW-C level, and the CRP level may all have an effect on the development of protective antibodies following vaccination.

Vaccines in adults with autoimmune inflammatory rheumatic disease: What are the knowledge and attitudes of physicians?

Objectives

The aim of this study was to evaluate the knowledge and practices about vaccination in adults with autoimmune inflammatory rheumatic diseases (AIRD) among primary care physicians (PCPs), internal medicine specialists (IMSs), and rheumatologists and to emphasize the importance of vaccination.

Patients and methods

Between March 2021 and April 2021, a total of 310 IMSs, PCPs, and rheumatologists (132 males, 178 females; mean age: 37.4±9.5 years; range, 24 to 64 years) were included. A web-based questionnaire was used in the study.

Results

Of the physicians, 87.7% were aware of that patients with AIRD were among adults with vaccination indications, but 53.9% reported that they knew about recommended vaccines, and 53.2% recommended vaccines to their patients. The most common reasons for not recommending vaccination were reservations about the drugs used (22.3%) and lack of information (17.7%). Those with longer practice as physicians and older physicians had less knowledge about the vaccine than the other participants. While 59.7% of the participants thought that the vaccination plans of the patients should be made by the rheumatologist, the rate of PCPs who did not prefer to apply the planned vaccines in the first step was 50.7%. A total of 50% of the participants did not recommend the administration of the COVID-19 vaccine in a primary healthcare institution to those receiving immunosuppressive therapy.

Conclusion

Considering that one of the major obstacles to adult vaccination is the physician's refusal to recommend it, our study highlights the missing points in the vaccination knowledge and approach of physicians. Providing advice on adult vaccination and immunization of risky groups to more physicians and periodic training to prevent loss of knowledge after graduation may contribute to an increase in the vaccination rate of adults with AIRD.

The Flare of Rheumatic Disease After SARS-CoV-2 Vaccination: A Review

As the coronavirus disease 2019 (COVID-19) pandemic continues worldwide, vaccination has been considered an effective measure to protect people from the COVID-19 and end the pandemic. However, for patients with rheumatic diseases (RD), concern for the induction of RD flare may combat the enthusiasm for vaccination. In general, current evidence doesn’t support the increased risk of disease flare after COVID-19 vaccination. However, the disease flare of RDs may be triggered by COVID-19 vaccinations, especially for patients with high disease activity. Most of these flares after vaccination are mild and need no treatment escalation. Considering the benefits and risks, RD patients are recommended to receive the COVID-19 vaccination but should be vaccinated when the RDs are in stable states.

Immunogenicity of the third and fourth BNT162b2 mRNA COVID-19 boosters and factors associated with immune response in patients with SLE and rheumatoid arthritis

Objectives

To evaluate the safety and immunogenicity of third and fourth BNT162b2 boosters in patients with SLE and rheumatoid arthritis (RA).

Methods

Patients with SLE and RA aged 18–65 years who completed a series of inactivated, adenoviral vector, or heterogenous adenoviral vector/mRNA vaccines for at least 28 days were enrolled. Immunogenicity assessment was done before and day 15 after each booster vaccination. The third BNT162b2 booster was administered on day 1. Patients with suboptimal humoral response to the third booster dose (antireceptor-binding domain (RBD) IgG on day 15 <2360 BAU/mL) were given a fourth BNT162b2 booster on day 22.

Results

Seventy-one patients with SLE and 29 patients with RA were enrolled. The third booster raised anti-RBD IgG by 15-fold, and patients with positive neutralising activity against the Omicron variant increased from 0% to 42%. Patients with positive cellular immune response also increased from 55% to 94%. High immunosuppressive load and initial inactivated vaccine were associated with lower anti-RBD IgG titre. Fifty-four patients had suboptimal humoral responses to the third booster and 28 received a fourth booster dose. Although anti-RBD IgG increased further by sevenfold, no significant change in neutralising activity against the Omicron variant was observed. There were two severe SLE flares that occurred shortly after the fourth booster dose.

Conclusions

The third BNT162b2 booster significantly improved humoral and cellular immunogenicity in patients with SLE and RA. The benefit of a short-interval fourth booster in patients with suboptimal humoral response was unclear.

Antibody titers after a third dose of the SARS-CoV-2 BNT162b2 vaccine in immunocompromised adults in Greece: Is a fourth dose necessary?

Real‐world data suggest that protection against COVID‐19 declines a few months after vaccination, particularly in the elderly and immunocompromised individuals. Our study aimed to analyze the humoral response induced by a third supplemental dose of BNT162b2 vaccine in a mixed group of immunocompromised individuals by determining anti‐spike (anti‐S) IgG antibody titers at baseline (pre‐third vaccine dose) and 4 weeks after the dose. Serum samples were obtained from a total group of 85 immunocompromised individuals (history of cancer: n = 20, lymphoma: n = 4, leukemia: n = 3, transplant recipients: n = 4, autoimmune disease: n = 42, inflammatory disease: n = 6, autoimmune diabetes type 1: n = 6) all of whom had previously received a two‐dose schedule of the vaccine. The average number of days between second and third dose was 139.6145 (±41.39071). The overall IgG GMCs 4 weeks postvaccination were increased by more than 35 times (fold change = 35.30, p < 0.001). Fold changes were not significantly correlated with underlying condition, age, sex nor with days between second and third dose. Considering the predominance of omicron variants in the current period and the results of studies showing a decrease in the effectiveness of the third dose after 10 weeks we highly recommend a fourth dose to this vulnerable population group.

Serological Response to BNT162b2 Anti-SARS-CoV-2 Vaccination in Patients with Inflammatory Rheumatic Diseases: Results From the RHEUVAX Cohort

Objective

In the light of the current COVID-19 epidemic and the availability of effective vaccines, this study aims to identify factors associated with non-response to anti-SARS-CoV-2 vaccines as immunological alteration associated with immune rheumatic diseases (IRD) and immunosuppressive medications may impair the response to vaccination.

Methods

Volunteers in the health profession community with IRD, age, and sex-matched controls (CTRL) who underwent vaccination with two doses of BNT162b2 were recruited for this study. Anti-Trimeric Spike protein antibodies were assayed eight ± one weeks after the second vaccine dose. Univariate and logistic regression analyses were performed to identify factors independently associated with non-response and low antibody titers.

Results

Samples were obtained from 237 IRD patients (m/f 73/164, mean age 57, CI 95% [56-59]): 4 autoinflammatory diseases (AI), 62 connective tissue diseases (CTD), 86 rheumatoid arthritis (RA), 71 spondylarthritis (SpA) and 14 vasculitis (Vsc). 232 CTRL were recruited (m/f 71/161, mean age 57, CI 95% [56-58]). Globally, IRD had a lower seroconversion rate (88.6% vs 99.6%, CI 95% OR [1.61-5.73], p&lt;0.001) and lower antibody titer compared to controls (median (IQR) 403 (131.5-1012) versus 1160 (702.5-1675), p&lt;0.001). After logistic regression, age, corticosteroid (CCS), Abatacept and Mycophenolate Mofetil (MMF) use were associated with non-response. Lower antibody titer was associated with the use of MMF, ABA, CCS, Rituximab, tumor necrosis factor inhibitor, JAK inhibitors, and higher age.

Conclusion

The response to anti-SARS-CoV-2 vaccines is often impaired in IRD patients under treatment and may pose them at higher risk of severe COVID-19. Specific vaccination protocols are desirable for these patients.

The COVID-19 vaccine: Attitudes and vaccination in patients with autoimmune inflammatory rheumatic diseases

Background

We examined attitudes toward the COVID‐19 vaccine, potential factors underlying these attitudes, and ways to increase vaccination willingness in autoimmune inflammatory rheumatic diseases (AIIRD) patients.

Methods

A multicenter, web‐based, observational survey using an online questionnaire was conducted among AIIRD patients aged ≥18 years from May 24, 2021, to June 3, 2021. Participants were 3104 AIIRD patients (2921 unvaccinated and 183 vaccinated).

Results

Of the unvaccinated patients, 32.9% were willing to receive the COVID‐19 vaccine, 45.0% were uncertain, and 14.8% were unwilling. When vaccination was recommended by physicians, patients' willingness increased to 93.8%. Participants' main concerns were that the vaccine may aggravate AIIRD disease (63.0%) and may cause vaccine‐related adverse events (19.9%). Female patients were less likely to be vaccinated. However, patients who had children aged ≤18 years were more willing to be vaccinated. In addition, vaccination willingness was higher in patients with trust in the safety and efficacy of the COVID‐19 vaccine. Notably, 183 (5.9%) patients were vaccinated. The major vaccination side effects were injection reaction, myalgia, and fatigue. At a median follow‐up of 88 (38, 131) days, patients' disease activities were stable.

Conclusions

The findings show that AIIRD patients were unwilling to receive the COVID‐19 vaccine because of fears of potential disease exacerbation and additional adverse events. Sociodemographic characteristics and concerns about COVID‐19 disease and vaccines had a significant effect on vaccination willingness.

The percentage of patients willing to receive the COVID‐19 vaccine greatly increased when vaccination was recommended by a physician.

Gender, marital status, age of the patients' children, smoking, trust in the safety and efficacy of the vaccine, and previous vaccinations had significant effects on the willingness of patients with AIIRDs to receive the COVID‐19 vaccine.

The data from vaccinated patients indicated no aggravation of AIIRD or additional adverse events.

Attitudes towards and safety of the SARS-CoV-2 inactivated vaccines in 188 patients with systemic lupus erythematosus: a post-vaccination cross-sectional survey

Vaccination is key in mastering the COVID-19 pandemic. Data on attitudes towards and safety of the SARS-CoV-2 inactivated vaccines in patients with systemic lupus erythematosus (SLE) are limited. A post-vaccination cross-sectional survey was conducted to obtain data on attitudes towards and safety of the SARS-CoV-2 inactivated vaccines in SLE patients compared to healthy controls. A post-vaccination cross-sectional survey was conducted in 188 patients with SLE and in 190 healthy controls who had received at least one dose of SARS-CoV-2 inactivated vaccine to find out post-vaccination adverse event (AE) or SLE flares. A total of 188 patients with SLE and 190 healthy controls vaccinated with the two-dose regimen SARS-CoV-2 inactivated vaccine were enrolled in the study. The two groups were matched in age, sex, medical background, income, and education level. All the SLE patients were in disease remission or with low disease activity with a median age of 35 years, a sex constituent ratio of 87.4% female, and a median disease duration of 4 years. SLE patients had much more concerns about vaccination safety (44.7% vs. 15.8%, P < 0.001), and were much less willing to get vaccinated (57.4% vs. 88.4%, P < 0.001). SLE patients had more mild adverse events after the first vaccine dose (43.6% vs. 25.3%, P = 0.008), and less mild adverse events after the second vaccine dose (19.8% vs. 34.9%, P = 0.024), compared with healthy controls. The AEs were minor and there were no serious or major adverse events in both groups. In patients with SLE, the post-vaccination disease activity remained stable. One previously undiagnosed female progressed into symptomatic SLE after one week of vaccination. Although SLE patients had concerns about the safety of the SARS-CoV-2 vaccines, the inactivated vaccination was safe in patients with stable SLE.

Dose-Dependent Impairment of the Immune Response to the Moderna-1273 mRNA Vaccine by Mycophenolate Mofetil in Patients with Rheumatic and Autoimmune Liver Diseases

The purpose of this study was to evaluate the efficacy and safety of the Moderna-1273 mRNA vaccine for SARS-CoV-2 in patients with immune-mediated diseases under different treatments. Anti-trimeric spike protein antibodies were tested in 287 patients with rheumatic or autoimmune diseases (10% receiving mycophenolate mofetil, 15% low-dose glucocorticoids, 21% methotrexate, and 58% biologic/targeted synthetic drugs) at baseline and in 219 (76%) 4 weeks after the second Moderna-1273 mRNA vaccine dose. Family members or caretakers were enrolled as the controls. The neutralizing serum activity against SARS-CoV-2-G614, alpha, and beta variants in vitro and the cytotoxic T cell response to SARS-CoV-2 peptides were determined in a subgroup of patients and controls. Anti-SARS-CoV-2 antibody development, i.e., seroconversion, was observed in 69% of the mycophenolate-treated patients compared to 100% of both the patients taking other treatments and the controls (p < 0.0001). A dose-dependent impairment of the humoral response was observed in the mycophenolate-treated patients. A daily dose of >1 g at vaccination was a significant risk factor for non-seroconversion (ROC AUC 0.89, 95% CI 0.80−98, p < 0.0001). Moreover, in the seroconverted patients, a daily dose of >1 g of mycophenolate was associated with significantly lower anti-SARS-CoV-2 antibody titers, showing slightly reduced neutralizing serum activity but a comparable cytotoxic response compared to other immunosuppressants. In non-seroconverted patients treated with mycophenolate at a daily dose of >1 g, the cytotoxic activity elicited by viral peptides was also impaired. Mycophenolate treatment affects the Moderna-1273 mRNA vaccine immunogenicity in a dose-dependent manner, independent of rheumatological disease.

Safety of COVID-19 vaccines and disease flares after vaccines in children with rheumatic disease

OBJECTIVES

Wide spread availability of safe and effective vaccines for COVID-19 in all countries is the best hope to end the COVID-19 pandemic. However, in developing countries, the hesitancy of the society about vaccination is an important problem in terms of public health. This study aimed to investigate the acceptability and tolerability of COVID-19 vaccines in the pediatric population diagnosed with rheumatic disease, as well as the attitudes towards these vaccines.

METHODS

This is an observational, cross sectional, single center study. Pediatric patients with at least one diagnosis of rheumatic disease were included in this study to investigate patient and family acceptability and safety of COVID-19 vaccines.

RESULTS

A total of 228 patients with rheumatic disease were included in this study. Ninety nine (43.4%) of the patients were juvenile idiopathic arthritis. One hundred and five (46%) of the patients were using biological agent treatment for their rheumatic disease, whereas 123 (54%) of the patients were not. No serious adverse effect related to the COVID-19 vaccine were observed in any of the patients. No disease activation was observed in any of them.

CONCLUSION

There are only a few studies evaluating of the safety and disease flare of COVID-19 vaccines in children with rheumatic disease. Although this study has some limitations, such as the small sample size of patients with different diagnoses, it appears that there is no increase in COVID-19 vaccination-related harms in the patients with rheumatic disease.
