Challenges and opportunities in access to care for systemic lupus erythematosus patients across Europe and worldwide.

SLE presents significant challenges for patients and health-care professionals (HCPs), both across Europe and worldwide. Improving health-care outcomes for patients with SLE requires a comprehensive understanding of patient disease pathways. In particular, the geographical distance between SLE patients and specialized care centres, combined with the scarcity of rheumatologists, exacerbates delays in diagnosis and management. Also, the initial SLE symptoms can often be non-specific, and providing guidelines for primary HCPs and other non-specialists is extremely important. Improvement in access to treatment is also important, with several recently approved therapies for SLE not being available in several European countries and many low- and middle-income countries (LMICs). Furthermore, in the LMICs in which these treatments are available, they are not always covered by the health-care system, making their access almost impossible for those of lower socio-economic status. A number of provisions are already in place within the European Union, to improve access to care for patients with rare and complex diseases, including those with SLE. In particular, European Reference Networks (ERNs), such the ERN for Autoimmune Diseases ReCONNET, are virtual networks involving HCPs across Europe with the aim of improving the care of patients with rare and complex diseases that require highly specialized treatment and a concentration of knowledge and resources. In addition, lupus patient organizations such as Lupus Europe play a crucial role in raising awareness of SLE and advocating for improved access to care. Together, we can work towards a future where all people living with lupus receive the comprehensive and timely care they deserve.

Low Disease Activity Early in the Course of Systemic Lupus Erythematosus.

In patients with systemic lupus erythematosus (SLE), remission and low disease activity (LDA) have been shown to be protective of damage accrual, mortality, and flares; they have also been shown to be associated with a better health-related quality of life.1 However, the large majority of published studies include patients with long-standing disease.

Unveiling the Link Between Antiphospholipid Antibodies and Cognitive Dysfunction in the Almenara Lupus Cohort.

OBJECTIVE: Cognitive dysfunction is a prevalent manifestation of systemic lupus erythematosus (SLE). There is evidence for the role of antiphospholipid (aPL) antibodies on its etiopathogenesis. Our objective was to identify the association between aPL antibodies and cognitive dysfunction in SLE patients. METHODS: This cross-sectional study included 135 patients evaluated from March 2015 to October 2017 at one center. Cognitive deficit was measured using the NEUROPSI test. Disease activity and damage were ascertained using the SLEDAI-2K (SLE Disease Activity Index 2000) and the SDI (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), respectively; aPL antibodies were measured by enzyme-linked immunosorbent assay. The association between cognitive dysfunction and aPL antibodies was evaluated using univariable and multivariable linear regression models adjusted for age, sex, education, socioeconomic status, disease duration, SLEDAI-2K, SDI, mean current dose of prednisone, time of exposure to glucocorticoids, and drug use (immunosuppressants, hydroxychloroquine, aspirin, and warfarin). RESULTS: One hundred thirty-one patients (97.1%) were women; their mean (SD) age was 46.6 (12.5) years; 59 patients (43.7%) had positivity for at least 1 aPL antibody. IgM anticardiolipin (aCL) was positive in 24.5%, IgG in 13.5%, IgM aß2GP1 in 16.8%, IgG anti-ß2 glycoprotein in 24.6%, and the lupus anticoagulant in 5.3%. Ninety patients (66.7%) had some cognitive dysfunction. In the univariable analysis, a significant correlation between the NEUROPSI score and IgM aCL antibodies was found (B = -20.87 [SE, 3.2]; p < 0.001), which remained significant in the multivariable model (B = -13.89 [SE, 3.14]; p < 0.001). CONCLUSIONS: IgM aCL antibodies are associated with cognitive dysfunction in patients with SLE. Larger and longitudinal studies are needed to assess the impact of these findings.

Rituximab as Treatment for Lupus Nephritis: Data From the Peruvian ALMENARA Lupus Cohort.

OBJECTIVE: The aim of this study was to evaluate the response to rituximab (RTX) as treatment for lupus nephritis (LN) in a Latin American Lupus cohort. METHODS: The medical records from LN patients from a single-center cohort spanning between January 2012 and December 2020 were reviewed. Demographic factors (age at diagnosis and baseline, gender), disease duration, previous and concomitant treatments, serum creatinine, and 24-hour proteinuria (24-HP) levels at baseline, and 6th and 12th months were obtained. Complete response (CR) or responder status was defined according to the LUNAR, AURORA-1, and BLISS-LN trials. RESULTS: Thirty-six patients received RTX as induction treatment; 32 (88.9%) were women. Their age at baseline and disease duration were 32.6 (11.7) and 7.6 (6.5) years, respectively. The time between renal biopsy and RTX use was 2.64 (4.41) years. At baseline, serum creatinine and 24-HP levels were 1.5 (1.5) mg/dL and 3.4 (2.8) g, respectively. At months 6 and 12, serum creatinine levels were 1.6 (1.6) and 1.6 (1.5) mg/dL, and 24-HP were 2.2 (2.2) and 1.6 (1.5) g, respectively. According to LUNAR and AURORA-1 criteria, CR at 6th and 12th months were 6/34 (17.6%) and 8/30 (26.7%) and 6/34 (17.6%) and 7/31 (22.6%) patients, respectively. According to BLISS-LN criteria, responders at 6th and 12th months were 9/34 (26.5%) and 10/31 (32.3%) patients, respectively. CONCLUSIONS: CR and responder status were reached in less than one third of LN patients treated with RTX, regardless of the criteria used to define them. However, serum creatinine levels did not increase, and there was a decrease in proteinuria levels during the follow-up.

The Lupus Foundation of America-Rapid Evaluation of Activity in Lupus Clinician-Reported Outcome Predicts Damage in Patients With Systemic Lupus Erythematosus. Data From the Almenara Lupus Cohort.

OBJECTIVE: To evaluate the predictive value of the LFA-REAL ClinRO (Lupus Foundation of America Rapid Evaluation of Activity in Lupus clinician-reported outcome) on damage accrual in systemic lupus erythematosus patients. METHODS: Data from a prevalent lupus cohort were used. The LFA-REAL ClinRO includes 9 domains: mucocutaneous (global and 3 subdomains), musculoskeletal (global and 2 subdomains), cardiorespiratory, neuropsychiatric, renal, hematological, constitutional, vasculitis, and other (it allows for other or rare manifestations). For each domain, a 0- to 100-mm visual analog scale is used, and global domains are included except for the mucocutaneous and musculoskeletal domains where the subdomains are included; it allows for 3 manifestations under "other," so the score ranges from 0 to 1400 (sum of 14 in the visual analog scale). Damage was assessed with the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index. Generalized estimating equations were performed, being the outcome the increase in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index; confounders from the previous visit were included; adjusted multivariable models were done. Incidence rate ratios per 10-unit increase in the LFA-REAL ClinRO were reported. Similar models were performed to evaluate the impact of the SLEDAI-2K (SLE Disease Activity Index) and physician global assessment on damage to determine which measure would better predict damage accrual. RESULTS: Three-hundred thirty-one patients and 1425 visits were included, 1.9 (SD 1.2) years of follow-up. Disease duration at baseline was 10.7 (7.4) years. The mean LFA-REAL ClinRO was 18.2 (SD 30.7). During the follow-up visits, 63 (17.9%) patients accrued damage once; 4 (1.1%) accrued damage twice. The LFA-REAL ClinRO was predictive of damage accrual even after adjustment for possible confounders (incidence rate ratio 1.10 (95% confidence interval 1.04-1.16; p < 0.001). Similar results were obtained using the SLEDAI-2K and the physician global assessment. CONCLUSION: The LFA-REAL ClinRO is predictive of damage accrual, even after adjusting for possible confounders.

Performance of the 2019 American College of Rheumatology/European League Against Rheumatism Classification Criteria for IgG4-Related Disease in a Latin American Cohort.

BACKGROUND/OBJECTIVE: The 2019 American College of Rheumatology/European League Against Rheumatism Classification Criteria (2019 AECC) for IgG4-related disease (IgG4-RD) is considered a significant advancement in the study of this condition. Most studies evaluating their performance have focused on White and Asian patients, leaving a knowledge gap regarding Latin American populations. Therefore, this study aimed to assess the performance of the 2019 AECC for IgG4-RD in a cohort of Latin American patients. METHODS: A multicenter medical records review study was conducted, involving centers from Argentina, Chile, Mexico, Peru, and Uruguay. Data on IgG4-RD patients and mimicker conditions were collected through a standardized online form. The criterion standard for diagnosing IgG4-RD was based on the fulfillment of the Comprehensive Diagnostic Criteria for IgG4-RD and/or the Consensus Statement on Pathology. The 2019 AECC was retrospectively applied. RESULTS: We included 300 patients, with 180 (60%) having IgG4-RD and 120 (40%) having mimicker conditions. The 2019 AECC had a sensitivity of 66.7% and a specificity of 100%. Sensitivity increased to 73.3% when disease-specific autoantibody items were removed, without affecting specificity. The true-positive cases had more involved organs, a higher availability of biopsy results, and were more likely to belong to the Mikulicz/systemic and proliferative phenotypes. CONCLUSIONS: The use of the 2019 AECC for IgG4-RD in a Latin American population confirms its high specificity in excluding those without the disease. The presence of concomitant autoimmune diseases and clinically nonsignificant disease-specific autoantibodies excludes a significant number of patients from fulfilling the criteria.

Improving access to SLE therapies in low and middle-income countries.

SLE increases disease burden in those affected with it, and that is particularly the case in low- and middle-income countries. The 2019 Addressing Lupus Pillar of Health Advancement project is a multiphase initiative whose objective is to recognize, hierarchize and establish approaches for diligent SLE research, care and access to healthcare. Lack of access to high-cost medications that have been shown to be efficacious in the short term and that potentially reduce damage in SLE is a complex issue. In this review, we highlight opportunities and plans of action to diminish costs and improve access to therapies, which should be recognized and executed, preferably within regional strategies with multiple stakeholders (including supranational organizations, governments, the pharmaceutical industry, medical societies and the general population) connected with and grounded in structured and clear cost-effectiveness analysis.

The Rise and Rise of Lupus.

Despite how difficult the early diagnosis of systemic lupus erythematosus (SLE) is, which is mainly due to the heterogeneity and non-specificity of its clinical manifestations, SLE is currently being diagnosed more frequently than in past decades. In fact, there has been an increase in the incidence and prevalence of SLE over the last four decades; this can be explained by a number of reasons including a better knowledge of the pathogenesis of the disease which allows its earlier diagnosis, the rising ethnic and racial diversity of the world population, the use of the 2019 EULAR/ACR criteria that allows classifying patients earlier, and improvements in survival over the last decades, which results in an increase in the prevalent cases of SLE. In this article, we will also review the genetic, environmental, and lifestyle factors, that are reported to increase the risk of developing SLE and how preventive strategies through a clinical care pathway may prevent or delay the development of SLE and improve these patients' outcomes.

Predictors of severe hemolytic anemia and its impact on major outcomes in systemic lupus erythematosus: Data from a multiethnic Latin American cohort.

OBJECTIVE: To determine the predictors of the occurrence of severe autoimmune hemolytic anemia (AIHA) and its impact on damage accrual and mortality in SLE patients. METHODS: Factors associated with time to severe AIHA (hemoglobin level ≤7 g/dL) occurring from the onset of SLE symptoms were examined by Cox proportional hazards regressions. The association of severe AIHA with mortality was examined by logistic regression analyses while its impact on damage was by negative binomial regression. RESULTS: Of 1,349 patients, 49 (3.6%) developed severe AIHA over a mean (SD) follow-up time of 5.4 (3.8) years. The median time from the first clinical manifestation to severe AIHA was 111 days (IQR 43-450). By multivariable analysis, male sex (HR 2.26, 95% CI 1.02-4.75, p = 0.044), and higher disease activity at diagnosis (HR 1.04, 95% CI 1.01-1.08, p = 0.025) were associated with a shorter time to severe AIHA occurrence. Of the SLEDAI descriptors, only hematologic (leukopenia and/or thrombocytopenia) showed a certain trend toward significance in the multivariable analysis (HR 2.36, 95% CI 0.91-6.13, p = 0.0772). Severe AIHA contributed neither to damage nor to mortality. CONCLUSIONS: Severe AIHA occurs during the early course of SLE. Male sex and higher disease activity at diagnosis emerged as independent predictors of a shorter time to severe AIHA occurrence. Although not statistically significant, hematological abnormalities at SLE diagnosis could predict the occurrence of severe AIHA in a shorter time. Damage and mortality did not seem to be impacted by the occurrence of severe AIHA.

The association between lupus serology and disease outcomes: A systematic literature review to inform the treat-to-target approach in systemic lupus erythematosus.

INTRODUCTION: Serological markers such as anti-double stranded (ds)DNA antibodies and complement fractions C3/C4, are integral components of disease activity assessment in patients with systemic lupus erythematosus (SLE). However, it remains uncertain whether treatment should aim at restoration of serological abnormalities. OBJECTIVES: To analyze and critically appraise the literature on the prognostic impact of active lupus serology despite clinical disease quiescence. METHODS: A systematic literature review was performed in PubMed and EMBASE using the PICOT(S) (population, index, comparator, outcome(s), timing, setting) system to identify studies evaluating the association of serum anti-dsDNA, C3 and C4 levels assessed at the time of clinical remission or during the disease course, against the risk for impending flares and organ damage. Risk of bias was determined by the Quality in Prognosis Studies and ROB2 tools for observational and randomized controlled studies, respectively. RESULTS: Fifty-three studies were eligible, the majority having moderate (70.6%) or high (11.8%) risk of bias and not adequately controlling for possible confounders. C3 hypocomplementemia during stable/inactive disease was associated with increased risk (2.0 to 3.8-fold) for subsequent flare in three out of seven relevant studies. Three out of four studies reported a significant effect of C4 hypocomplementemia on flare risk, including one study in lupus nephritis (likelihood ratio-positive 12.0). An increased incidence of flares (2.0 to 2.8-fold) was reported in 11 out of 16 studies assessing the prognostic effect of high anti-dsDNA, and similarly, the majority of studies yielded significant relationships with renal flares. Six studies examined the effect of combined (rather than individual) serological activity, confirming the increased risk (2.0 to 2.7-fold) for relapses. No consistent association was found with organ damage. CONCLUSION: Notwithstanding the heterogeneity and risk of bias, existing evidence indicates a modest association between abnormal serology and risk for flare in patients with stable/inactive SLE. These findings provide limited support for inclusion of serology in the treat-to-target approach but rationalize to further investigate their prognostic implications especially in lupus nephritis.

Addressing health disparities as a function of ethnicity in systemic lupus erythematosus patients.

Systemic lupus erythematosus (SLE) is an autoimmune disorder with significant health disparities, as it disproportionately and more severely affects vulnerable and disadvantaged population groups in the United States and around the world, that is, women, ethnic minorities, individuals living in poverty, less educated, and lacking medical insurance. Both, genetic and non-genetic factors, contribute to these disparities. To overcome these health disparities and reduce poor outcomes among disadvantaged SLE populations, interventions on non-genetic amendable factors, especially on social health determinants, are necessary.

The SLICC-FI Predicts Damage Accrual in SLE Patients. Data From the Almenara Lupus Cohort.

OBJECTIVE: To evaluate the Systemic Lupus International Collaborating Clinics Frailty Index (SLICC-FI) as a predictor of damage accrual in a primarily Mestizo SLE patient cohort. METHODS: Patients from a single-center prevalent cohort were included. Damage accrual was defined as the increase in the SLICC/American College of Rheumatology (ACR) damage index (SDI) scores between the baseline and the last visits. The SLICC-FI was measured at baseline. Univariable and multivariable Cox regression models were performed to determine the association between the baseline SLICC-FI (per 0.05 increase) and the increase in the SDI, adjusted for possible confounders. Alternative analyses using negative binomial regression models including the difference between the last and the first SDI as outcome were performed. RESULTS: Of the 265 patients included, 248 (93.6%) were female with mean (SD) age of 35.1 (13.6) years at diagnosis. At baseline, mean (SD) SLE disease duration was 7.3 (6.5) years, SDI was 1.0 (1.2) and the SLICC-FI was 0.22 (0.05). After a mean (SD) of 5.2 (2.2) years of follow-up, the SDI increased in 126 (47.5%) patients, and the final mean (SD) SDI score was 1.7 (1.7). Higher SLICC-FI scores at baseline predicted greater damage accrual in the univariable analysis [Hazard Ratio (HR) =1.38, (CI95% 1.16-1.65); p < 0.001] and in the multivariable model, after adjustment for possible confounders [HR = 1.30 (CI95% 1.02-1.66); p = 0.033]. CONCLUSION: SLICC-FI predicts the occurrence of damage accrual in a prevalent SLE Latin-American cohort with short or long disease duration, supporting the relevance of this index in the evaluation of SLE patients.

Metabolic syndrome predicts new damage in systemic lupus erythematosus patients: Data from the Almenara Lupus Cohort.

OBJECTIVES: This study aims to determine whether the MetS predicts damage accrual in SLE patients. METHODS: This longitudinal study was conducted in a cohort of consecutive SLE patients seen since 2012 at one single Peruvian institution. Patients had a baseline visit and then follow-up visits every 6 months. Patients with ≥ 2 visits were included. Evaluations included interview, medical records review, physical examination, and laboratory tests. Damage accrual was ascertained with the SLICC/ACR damage index (SDI) and disease activity with the SLEDAI-2K. Univariable and multivariable Cox-regression survival models were carried out to determine the risk of developing new damage. The multivariable model was adjusted for age at diagnosis; disease duration; socioeconomic status; SLEDAI; baseline SDI; the Charlson Comorbidity Index; daily dose; and time of exposure of prednisone (PDN), antimalarials, and immunosuppressive drugs. RESULTS: Two hundred and forty-nine patients were evaluated; 232 of them were women (93.2%). Their mean (SD) age at diagnosis was 35.8 (13.1) years; nearly all patients were Mestizo. Disease duration was 7.4 (6.6) years. The SLEDAI-2K was 5.2 (4.3) and the SDI, 0.9 (1.3). One hundred and eight patients (43.4%) had MetS at baseline. During follow-up, 116 (46.6%) patients accrued at least one new point in the SDI damage index. In multivariable analyses, the presence of MetS was a predictor of the development of new damage (HR: 1.54 (1.05-2.26); p < 0.029). CONCLUSIONS: The presence of MetS predicts the development of new damage in SLE patients, despite other well-known risk factors for such occurrence.

Relationship between care model and disease activity states and health-related quality of life in systemic lupus erythematosus patients.

OBJECTIVE: To assess whether the care model (comprehensive vs regular) has any impact on the clinical outcomes of systemic lupus erythematosus patients. METHODS: Between August 2019 and January 2020, we evaluated SLE patients being cared for at two Peruvian hospitals to define the impact of care model on disease activity state and health-related quality of life (HRQoL). Disease activity was ascertained with the SLEDAI-2K and the Physician Global Assessment (PGA) which allows to define Lupus Low Disease Activity State (LLDAS) and Remission. HRQoL was measured with the LupusQoL. The association between care model and disease activity (Remission and LLDAS) state was examined using a binary logistic regression model. The association with HRQoL was examined with a linear regression model. All multivariable analyses were adjusted for possible confounders. RESULTS: 266 SLE patients were included, 227 from the comprehensive care model and 39 from the regular care model. The regular care model was associated with a lower probability of achieving remission (OR 0.381; CI: 95% 0.163-0.887) and LLDAS (OR 0.363; CI: 95% 0.157-0.835). Regular care was associated with a better HRQoL in two domains (pain and emotional health). We found no association between the care model and the other HRQoL domains. CONCLUSION: A comprehensive care model was associated with the probability of achieving remission and LLDAS but had no apparent impact on the patients' HRQoL.

Impact of COVID-19 pandemic on patients with rheumatic diseases in Latin America.

The objective of our study was to describe knowledge, attitudes and practices of Latin-American rheumatology patients regarding management and follow-up of their disease during COVID-19 pandemic. A cross-sectional observational study was conducted using a digital anonymous survey. Rheumatic patients ≥ 18 years from non-English-speaking PANLAR countries were included. Our survey included 3502 rheumatic patients living in more than 19 Latin-American countries. Median age of patients was 45.8(36-55) years and the majority (88.9%) was female. Most frequently self-reported disease was rheumatoid arthritis (48.4%). At least one anti-rheumatic treatment was suspended by 23.4% of patients. Fear of contracting SARS-Cov2 (27.7%) and economic issues (25%) were the most common reasons for drug discontinuation. Self-rated disease activity increased from 30 (7-50) to 45 (10-70) points during the pandemic. Communication with their rheumatologist during the pandemic was required by 55.6% of patients, mainly by telephone calls (50.2%) and social network messages (47.8%). An adequate knowledge about COVID-19 was observed in 43% of patients. Patients with rheumatic diseases in Latin America were negatively affected by the COVID-19 pandemic. An increase in self-rated disease activity, a reduction in medication adherence, and hurdles for medical follow-up were reported. Teleconsultation was perceived as a valid alternative to in-person visits during the pandemic.

ANCA-Associated Vasculitis in Latin America: A Systematic Literature Review: About Their Epidemiology and Their Clinical Features.

ABSTRACT: Most of the existing literature, including epidemiological studies and clinical trials, on antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) include North American (mainly United States and Canada), European, and Asian populations. Few studies have focused on multiethnic populations such as the one from Latin America. Racial and ethnic differences in the incidence of AAV could partially explain the comparatively low number of AAV studies originating in Latin America. However, given the racial/ethnic diversity as well as socioeconomic differences existing in this region, better reporting of AAV presentations and outcomes in Latin America could highlight valuable gaps on the understanding and treatment of these patients. Recently, larger case series and studies have provided better clinical information regarding AAV patients in Latin American countries; however, further information is needed to address gaps such as risk factors, genetic profiles, clinical features, and predictors of clinical outcomes. For these reasons, we have performed a systematic literature review to enhance our understanding of AAV patients in Latin America. We have included 11 articles focused on the epidemiological and clinical features of AAV in Latin America; some similarities and differences with AAV in other regions are shown in these articles. We have identified differences in their prevalence across Latin American countries, which may reflect reporting bias or true ethnic differences among the countries. Our findings should encourage further investigation into AAV in Latin America; such studies will hopefully lead to the optimal management of these patients.

Controversies in Systemic Lupus Erythematosus: Are We Treating Our Patients Adequately?

ABSTRACT: Systemic lupus erythematosus (SLE) is characterized by great clinical heterogeneity. The objectives of its management are to make a timely diagnosis and to initiate treatment as promptly as possible so organ damage can be avoided while at the same time exposure to potentially toxic drugs is minimized so that its overall course and outcome improve. In reviewing the current literature, it became quite clear that there are specific topics in which controversies do exist. These include how to treat patients with incomplete lupus erythematosus, the real possibility of abandoning altogether the use of oral glucocorticoids, and the pros and cons of the use of cyclophosphamide and mycophenolate mofetil for the induction treatment of lupus nephritis. Herein we discuss different points of view regarding these still unresolved issues; these comments represent a debate that took place during the PANLAR Virtual Congress (Pan American League of Associations for Rheumatology) and that was organized by the PANLAR Lupus study group, GLADEL (Grupo Latino Americano De Estudio del Lupus) on September 19, 2020.

Predictors of Remission and Low Disease Activity in Rheumatoid Arthritis Patients: Results From the Follow-up of a Real-World Peruvian Cohort.

BACKGROUND: Clinical remission is the goal in rheumatoid arthritis (RA) management; however, this can be difficult to achieve in several parts of the world. Our objective was to determine predictors of remission and remission/low disease activity (LDA) in RA. METHODS: A longitudinal real-setting RA cohort was followed up (January 2016-2020). Predictors examined were sex, age at diagnosis, disease duration, socioeconomic status, tobacco use, rheumatoid factor titer, comorbidities (Charlson index), Simple Disease Activity Index (SDAI) score, disability (Multidimensional Disease Health Assessment Questionnaire), health-related quality of life (Short Form-36 questionnaire), glucocorticoid dose, biological/target synthetic disease-modifying antirheumatic drugs, and conventional DMARD (c-DMARD) use. Univariable and multivariable generalized estimating equation models were done to determine predictors of remission (at a given visit) and sustained remission (2 consecutives visits), using the SDAI definition (0 or <3.3). Similarly, remission/LDA (SDAI <11) predictors were examined. RESULTS: Five hundred thirty RA patients included the following: 160 patients (30.2%) achieved remission in at least 1 visit, and 126 patients (23.77%) achieved sustained remission. On the multivariable analysis glucocorticoid dose (odds ratio [OR], 1.060; 95% confidence interval [CI], 1.027-1.094; p = 0.004) and current (OR, 2.293; 95% CI, 1.811-2.903; p < 0.001) or past (OR, 1.383; 95% CI, 1.127-1.698; p = 0.002) use of c-DMARDs predicted remission/LDA in at least 1 visit, whereas the SDAI (OR, 0.951; 95% CI, 0.942-0.959; p < 0.001), Multidimensional Disease Health Assessment Questionnaire (OR, 0.648; 95% CI, 0.549-0.764; p < 0.001), and age at diagnosis (OR, 0.994; 95% CI, 0.990-0.998; p = 0.004) were negative predictors. As to sustained remission/LDA, current (OR, 2.012; 95% CI, 1.458-2.776: p < 0.001) or past (OR, 1.517; 95% CI, 1.155-1.993; p = 0.003) use of c-DMARDs, having a better Short Form-36 questionnaire physical component summary (OR, 1.022; 95% CI, 1.014-1.029; p < 0.001), and older age at diagnosis (OR, 1.013; 95% CI, 1.003-1.022; p = 0.008) predicted it, whereas SDAI (OR, 0.949; 95% CI, 0.933-0.965; p < 0.001) and medium low/low socioeconomic status (OR, 0.674; 95% CI, 0.500-0.909; p = 0.010) were negative predictors. CONCLUSION: During follow-up of this real-world RA cohort, c-DMARD use predicted remission and remission/LDA. In contrast, disease activity was a negative predictor.

Performance of the 2017 American College of Rheumatology/European League Against Rheumatism Provisional Classification Criteria for Antineutrophil Cytoplasmic Antibody-Associated Vasculitis in a Peruvian Tertiary Care Center.

AIM: To validate the new classification criteria for antineutrophil cytoplasmic antibody-associated vasculitis in a real-life Peruvian cohort of antineutrophil cytoplasmic antibody-associated vasculitis patients. METHODS: We reviewed medical records from a Peruvian tertiary care center from January 1990 to December 2019. Antineutrophil cytoplasmic antibody-associated vasculitis was diagnosed based on the 1990 American College of Rheumatology (ACR) criteria, the 2012 Chapel Hill Consensus Conference definitions, the European Medicines Agency (EMEA) algorithm, and the clinical acumen of the treating rheumatologists. We classified all patients using the "former criteria" (the 1990 ACR criteria for granulomatosis with polyangiitis [GPA] and eosinophilic GPA [EGPA] and the 1994 Chapel Hill Consensus Conference definition for microscopic polyangiitis [MPA]), the EMEA algorithm, and the "new criteria" (the 2017 ACR/European League Against Rheumatism Provisional Criteria). The level of agreement (using Cohen κ) was calculated using the clinical diagnosis as the criterion standard. RESULTS: We identified 212 patients, 12 of whom were excluded. One hundred fifty-four (77%) had MPA, 41 (20.5%) GPA, and 5 (2.5%) EGPA. The new criteria performed well for MPA (κ = 0.713) and EGPA (κ = 0.659), whereas the EMEA algorithm performed well for GPA (κ = 0.938). In the overall population, the new criteria showed better agreement (κ = 0.653) than the EMEA algorithm (κ = 0.506) and the former criteria (κ = 0.305). CONCLUSIONS: The 2017 ACR/European League Against Rheumatism Provisional Criteria showed better agreement for the clinical diagnosis of all the patients overall and had the best performance for MPA and EGPA. The EMEA algorithm had the best performance for GPA.

Rheumatology Training in Latin America: A Collaborative Study by the Pan American League of Associations for Rheumatology.

BACKGROUND/OBJECTIVE: Demand for rheumatology care has steadily increased in recent years. The number of specialists in this field, however, seems insufficient. No recent studies have diagnosed the attributes of rheumatology training in Latin America. METHODS: This is a descriptive cross-sectional study. We obtained data on each country through local rheumatologists of the Pan-American League Against Rheumatism, who acted as principal investigators for participating countries. Our sample was analyzed and described through means and standard deviations or through frequencies and percentages, depending on the variable. RESULTS: Countries with the most rheumatology-training programs were Brazil (n = 50), Argentina (n = 18), and Mexico (n = 15). Ecuador, Honduras, and Nicaragua do not have rheumatology-training programs. The countries with the most available slots for rheumatology residents were Brazil (n = 126) and Argentina (n = 36). To be admitted into rheumatology training, candidates were required to have completed graduate studies in internal medicine in 42.1% of the programs. In 8 countries (42.1%), residents are not required to pay tuition; the median cost of tuition in the remaining countries is US $528 (interquartile range, US $2153). CONCLUSIONS: Conditions associated with rheumatology training in Latin America vary. Significant differences exist in income and tuition fees for residents, for example, and 4 countries in Latin America do not currently offer programs. Information collected in this study will be useful when comparing the status of rheumatology services offered in Latin America with those in other countries. Most countries require a wider offering of rheumatology-training programs, as well as more available slots.
