Objective: To evaluate the humoral response to and impact of SARS-CoV-2 vaccination in patients with systemic lupus erythematosus in a multicenter cohort design.

Methods: Data for this analysis were obtained from the Study of Safety, Effectiveness and Duration of Immunity after Vaccination against SARS-CoV-2 in Patients with Immune-Mediated Inflammatory Diseases (SAFER), a prospective, multicenter, phase IV, real-world study conducted across different regions of Brazil from June/2021 to March/2024. Patients aged >18 years with systemic lupus erythematosus (SLE) who received any one of the SARS-CoV-2 vaccines approved by the Brazilian health regulatory agency (CoronaVac [inactivated SARS-CoV-2 vaccine], ChAdOx-1 [AstraZeneca], or BNT162b2 [Pfizer-BioNTech]) were included.

COVID-19 on patients with immune-mediated rheumatic disease: a comparative study of disease activity, fatigue, and psychological distress over six months.

Objectives: To compare the impact of COVID-19 on the clinical status and psychological distress of patients with immune-mediated rheumatic disease (IMRD) caused by SARS-CoV-2 infection with that of noninfected IMRD controls during a 6-month follow-up period.

Methods: The ReumaCoV Brazil is a longitudinal study designed to follow IMRD patients for 6 months after COVID-19 (patients) compared with IMRD patients without COVID-19 (controls). Clinical data, disease activity measurements and current treatments regarding IMRD and COVID-19 outcomes were evaluated in all patients.

Immunogenicity and Safety According to Immunosuppressive Drugs and Different COVID-19 Vaccine Platforms in Immune-Mediated Disease: Data from SAFER Cohort.

Background/objectives: The effectiveness of COVID-19 vaccine in patients with immune-mediated inflammatory diseases (IMID) depends on the underlying disease, immunosuppression degree and the vaccine regimens. We evaluate the safety and immunogenicity of different COVID-19 vaccine schedules.

Methods: The SAFER study: "Safety and effectiveness of the COVID-19 Vaccine in Rheumatic Disease", is a Brazilian multicentric prospective observational phase IV study in the real-life.

A charter to improve care for systemic lupus erythematosus.

Objectives: To develop evidenced recommendations to allow the global systemic lupus erythematosus (SLE) advocacy community to effectively advocate for change and improve care for patients with SLE.

Methods: A Global Working Group consisting of representatives from patient advocacy groups, professional organisations, and the SLE healthcare community defined key areas of unmet need in patients with SLE. Targeted principles for each area of unmet need guided a literature review to investigate the current global situation, pre-existing advocacy efforts, and best practices from other therapy areas.

Predictors of Hospitalization in Breakthrough COVID-19 among Fully Vaccinated Individuals with Immune-Mediated Rheumatic Diseases: Data from SAFER-Study.

Breakthrough COVID-19 (occurring in fully vaccinated people) has been described. Data on its characteristics among immune-mediated rheumatic disease (IMRD) patients are scarce. This study describes breakthrough COVID-19 occurring in IMRD patients participating in the SAFER-study, a Brazilian multicentric cohort evaluating the safety, effectiveness, and immunogenicity of SARS-CoV-2 vaccines in patients with autoimmune diseases.

Safety of CoronaVac and ChAdOx1 vaccines against SARS-CoV-2 in patients with rheumatoid arthritis: data from the Brazilian multicentric study safer.

Background: Patients with immune-mediated rheumatic diseases (IMRDs) have been prioritized for COVID-19 vaccination to mitigate the infection severity risks. Patients with rheumatoid arthritis (RA) are at a high risk of severe COVID-19 outcomes, especially those under immunosuppression or with associated comorbidities. However, few studies have assessed the safety of the COVID-19 vaccine in patients with RA.

Comparative study of two laboratory techniques for the detection of HLA-B27 in patients with axial spondyloarthritis: a cross-sectional analysis.

Background: The diagnostic and prognostic relevance of Human Leukocyte Antigen B-27 (HLA-B27) in Axial Spondyloarthritis (AxSpA) is undeniable, with 70% of Ankylosing Spondylitis (AS) patients carrying the B27 gene, contrasted with a mere 4.35% in the general population. Flow cytometry (FC) and Polymerase Chain Reaction (PCR) have emerged as the predominant techniques for routine HLA-B27 typing.

Methods: This 12-month, cross-sectional, COI study of patients with SLE (ACR 1997 Classification Criteria) collected data using patient interviews (questionnaires) and medical records, covering: SLE profile, resources used, morbidities, quality of life (12-Item Short Form Survey, SF-12), and loss of productivity.

Opportunities and challenges of lupus care in Latin America, the Middle East, and Asia-Pacific: A call to action.

Lupus remains a disease with a low prioritisation in the national agendas of many countries in Latin America, the Middle East, and Asia-Pacific, where there is a dearth of rheumatologists and limited access to new or even standard lupus treatments. There is thus an important need for education, advocacy, and outreach to prioritise lupus in these regions to ensure that patients receive the care they need. This article reviews some of the specific challenges facing the care and management of people with lupus in these regions and suggests strategies for improving patient outcomes.

Life expectancy and death pattern associated with systemic lupus erythematosus diagnosis in Brazil between 2000 and 2019.

Objectives: to evaluate the main factors associated with mortality and determine the life expectancy of SLE patients between 2000 and 2019 years in Brazil.

Methods: death data related to SLE available in the Brazilian Unified Health System (SUS) (DATASUS) were evaluated in all Brazilian states. Three groups of death causes potentially associated from SLE were evaluated: cardiovascular and kidney diseases and infections.

CCR5 promoter region polymorphisms in systemic lupus erythematosus.

This study investigated the impacts of CCR5 promoter region polymorphisms on the development of systemic lupus erythematosus (SLE) by comparing CCR5 genotypes and haplotypes from SLE patients with ethnically matched controls. A total of 382 SLE patients (289 European-derived and 93 African-derived) and 375 controls (243 European-derived and 132 African-derived) were genotyped for the CCR2-64I G > A (rs1799864), CCR5-59353 C > T (rs1799988), CCR5-59356 C > T (rs41469351), CCR5-59402 A > G (rs1800023) and CCR5-59653 C > T (rs1800024) polymorphisms through polymerase chain reaction-restriction fragment length polymorphism and direct sequencing. Previous data from CCR5Δ32 analysis was included in the study to infer the CCR5 haplotypes and as a possible confounding factor in the binary logistic regression.

Challenges in the Management of Psoriatic Arthritis in Latin America: A Systematic Review.

Purpose: In 2020, the International League of Associations for Rheumatology published recommendations for managing psoriatic arthritis (PsA), aiming to adapt the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis and the European Alliance of Associations for Rheumatology recommendations to low-income countries. At that time, the paucity of clinical studies examining the management of patients with PsA in Latin America was remarked on by the international working group. Therefore, the primary objective of this systematic literature review was to investigate the main challenges in managing PsA in Latin America as described in recent publications.

Factors associated with poor outcomes in SLE patients with COVID-19: Data from .

Objectives: To evaluate factors associated with COVID-19 severity outcomes in patients with systemic lupus erythematosus (SLE).

Methods: This was a cross-sectional analysis of baseline data of a prospective, multi-stage cohort study-"The ReumaCoV Brazil"-designed to monitor patients with immune-mediated rheumatologic disease (IMRD) during the SARS-CoV-2 pandemic. SLE adult patients with COVID-19 were compared with those without COVID-19.

Vitamin D supplementation modulates autophagy in the pristane-induced lupus model.

Introduction/objectives: Clinical evidence of skeletal muscle involvement is not uncommon in systemic lupus erythematosus (SLE). Because of the poor understanding of signaling pathways involved in SLE muscle wasting, the  aim of this study was to evaluate the effects of vitamin D supplementation on skeletal muscle in mice with pristane-induced lupus.

Methods: Balb/c mice with lupus-like disease induced by pristane injection were randomized into three groups: pristane-induced lupus (PIL; n = 10), pristane-induced lupus + vitamin D supplementation (PIL + VD; n = 10) and healthy controls (CO; n = 8).

Higher IgG level correlated with vitamin D receptor in the hippocampus of a pristane-induced lupus model.

Introduction/objectives: Patients with systemic lupus erythematosus (SLE) may have neurological complications, characterizing neuropsychiatric lupus (NPSLE). Studies have investigated alternative therapies such as vitamin D, which has an effect on the immune system and brain, to control manifestations of SLE. Experimental lupus models may be a good alternative to best study the immunological mechanisms underlying the development of NPSLE, and the animal model of pristane-induced lupus (PIL) may mimic SLE symptoms in humans.

gene polymorphisms and its relation to infection in Brazilian systemic lupus erythematosus patients: A 10-years follow-up study.

Introduction: Systemic lupus erythematosus (SLE) is a multifactorial disease and MBL2 genetic variants, which are associated to differential peripheral MBL levels, potentially affect its etiology and increase infection risk in this population.

Objective: To evaluate the potential association of MBL2 polymorphisms of the coding and promoter gene region and haplotypes on hospitalization, number of admission and days of admission for major infection causes in Brazilian SLE patients. Methods: 325 SLE patients from a southern Brazilian outpatient SLE clinic were genotyped in 2006 for MBL2 gene polymorphisms from coding and promoter region (rs1800450, rs1800451, rs5030737, rs11003125, and rs7096206) and followed until 2016.

Guidelines on COVID-19 vaccination in patients with immune-mediated rheumatic diseases: a Brazilian Society of Rheumatology task force.

Objective: To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process.

Methods: A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree.
