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.

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.

Joint Damage and Low Lean Body Mass in a Cohort of Peruvian Patients With Rheumatoid Arthritis.

OBJECTIVES: To determine the association between radiologic joint damage (JD) and a lower lean body mass (LBM) in rheumatoid arthritis (RA) patients. METHODS: A cross-sectional study from a single center established RA cohort. JD and appendicular LBM (arms and legs) were measured with the Sharp/van der Heijde (SvdH) score and dual x-ray absorptiometry expressed as kg/m 2 , respectively. A univariable analysis was used to determine the association between JD an LBM; then, a multivariable regression model was performed to evaluate the persistence of this association, adjusted by age, gender, disease duration, socioeconomic status (by the Graffar method), tobacco use, anticitrullinated protein antibody levels, Disease Activity Score in 28 joints for RA with erythrocyte sedimentation rate, glucocorticoid use (as prednisone equivalent), disease-modifying antirheumatic drug use, body mass index, and disability (by the multidimensional Health Assessment Questionnaire). RESULTS: Two hundred forty-seven patients were included; the average (SD) age was 63.0 (12.8) years, disease duration 20 (15.00) years, the total SvdH was 66 (86.75), and the aLBM was 13.6 (3.82) kg/m 2 . In the univariable analysis, a lower appendicular LBM was associated with higher SvdH score on the female population, in terms of the total ( B = -8.6, p < 0.01), bone erosion (-4.4, p < 0.01), and joint space narrowing (-4.2, p < 0.01) scores; this correlation remained in the multivariable analysis in terms of total SvdH ( B = -9.5, p < 0.01), bone erosion (-5.2, p < 0.01), and joint space narrowing (-4.3, p < 0.01). CONCLUSIONS: A lower LBM in female patients was associated with more severe JD independently of other variables examined. Strategies aimed at preserving LBM could have a favorable impact on the course of disease.

Characteristics associated with poor COVID-19 outcomes in individuals with systemic lupus erythematosus: data from the COVID-19 Global Rheumatology Alliance.

AIM: To determine characteristics associated with more severe outcomes in a global registry of people with systemic lupus erythematosus (SLE) and COVID-19. METHODS: People with SLE and COVID-19 reported in the COVID-19 Global Rheumatology Alliance registry from March 2020 to June 2021 were included. The ordinal outcome was defined as: (1) not hospitalised, (2) hospitalised with no oxygenation, (3) hospitalised with any ventilation or oxygenation and (4) death. A multivariable ordinal logistic regression model was constructed to assess the relationship between COVID-19 severity and demographic characteristics, comorbidities, medications and disease activity. RESULTS: A total of 1606 people with SLE were included. In the multivariable model, older age (OR 1.03, 95% CI 1.02 to 1.04), male sex (1.50, 1.01 to 2.23), prednisone dose (1-5 mg/day 1.86, 1.20 to 2.66, 6-9 mg/day 2.47, 1.24 to 4.86 and ≥10 mg/day 1.95, 1.27 to 2.99), no current treatment (1.80, 1.17 to 2.75), comorbidities (eg, kidney disease 3.51, 2.42 to 5.09, cardiovascular disease/hypertension 1.69, 1.25 to 2.29) and moderate or high SLE disease activity (vs remission; 1.61, 1.02 to 2.54 and 3.94, 2.11 to 7.34, respectively) were associated with more severe outcomes. In age-adjusted and sex-adjusted models, mycophenolate, rituximab and cyclophosphamide were associated with worse outcomes compared with hydroxychloroquine; outcomes were more favourable with methotrexate and belimumab. CONCLUSIONS: More severe COVID-19 outcomes in individuals with SLE are largely driven by demographic factors, comorbidities and untreated or active SLE. Patients using glucocorticoids also experienced more severe outcomes.

Very low prevalence of ultrasound-detected tenosynovial abnormalities in healthy subjects throughout the age range: OMERACT ultrasound minimal disease study.

OBJECTIVES: This study aimed to determine the prevalence of ultrasound-detected tendon abnormalities in healthy subjects (HS) across the age range. METHODS: Adult HS (age 18-80 years) were recruited in 23 international Outcome Measures in Rheumatology ultrasound centres and were clinically assessed to exclude inflammatory diseases or overt osteoarthritis before undergoing a bilateral ultrasound examination of digit flexors (DFs) 1-5 and extensor carpi ulnaris (ECU) tendons to detect the presence of tenosynovial hypertrophy (TSH), tenosynovial power Doppler (TPD) and tenosynovial effusion (TEF), usually considered ultrasound signs of inflammatory diseases. A comparison cohort of patients with rheumatoid arthritis (RA) was taken from the Birmingham Early Arthritis early arthritis inception cohort. RESULTS: 939 HS and 144 patients with RA were included. The majority of HS (85%) had grade 0 for TSH, TPD and TEF in all DF and ECU tendons examined. There was a statistically significant difference in the proportion of TSH and TPD involvement between HS and subjects with RA (HS vs RA p<0.001). In HS, there was no difference in the presence of ultrasound abnormalities between age groups. CONCLUSIONS: Ultrasound-detected TSH and TPD abnormalities are rare in HS and can be regarded as markers of active inflammatory disease, especially in newly presenting RA.

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.

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.

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.

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.

Let's Talk About Lupus. Overview of an Innovative, High-Reach, Online Program to Fill the Education Gaps of Latin Americans Living With Lupus.

BACKGROUND/OBJECTIVE: The Latin American population living with lupus lacks reliable and culturally competent health education resources. We describe a Spanish and Portuguese online program to educate Latin American people about lupus. METHODS: An extensive network of Latin American stakeholders participated in the program design, implementation, dissemination, and evaluation. Patients and rheumatologists selected core topics. Rheumatologists prepared the content using evidence-based data. Adaptations were conducted to meet the audience's health literacy and cultural values. Social media was used to post audiovisual resources and facilitate users' interactions with peers and educators, and a Web site was created to offer in-depth knowledge. RESULTS: The most massive outreach was through Facebook, with more than 20 million people reached and 80,000 followers at 3 months, between the Spanish and Portuguese pages. Nearly 90% of followers were from Latin America. A high engagement and positive responses to a satisfaction survey indicate that Facebook users valued these resources. The Spanish and Portuguese Web sites accumulated more than 62,000 page views, and 71.7% of viewers were from Latin American. CONCLUSIONS: The engagement of patients and stakeholders is critical to provide and disseminate reliable lupus education. Social media can be used to educate and facilitate interactions between people affected by lupus and qualified health care professionals. Social media-based health education has extensive and scalable outreach but is more taxing for the professional team than the Web site. However, the Web site is less likely to be used as a primary education source by Latin American people because they value social interactions when seeking lupus information.

Health-Related Quality of Life and fatigue are associated with a higher work productivity impairment in systemic lupus erythematosus patients: Data from the Almenara Lupus Cohort.

Objectives: This study aims to determine the factors associated with absenteeism, presenteeism, and overall work impairment in patients with systemic lupus erythematosus (SLE).Methods: A total of 133 consecutive working patients with SLE were assessed between October 2017 and December 2018, using a standardized data collection form. Sociodemographic, disease, and work-related variables were collected. Work productivity and activity impairment (WPAI) was assessed with the respective questionnaire; absenteeism and presenteeism due to overall health and symptoms during the past 7 days were scored. Linear regression models were performed to determine the factors associated with absenteeism, presenteeism, and overall work impairment. Potential factors included were age at diagnosis, gender, socioeconomic status, educational level, SLEDAI, SLICC/ACR damage index (SDI), FACIT-Fatigue, and the domains of the LupusQoLResults: The mean age at diagnosis was 32.2 years (11.8); 121 (91.7%) were female. Nearly all patients were Mestizo. The mean percent of time for absenteeism was 5.0 (12.9), it was 28.5 (26.4) for presenteeism, and it was 31.3 (27.2) for overall work impairment. In the multiple regression analysis, factors associated with absenteeism were disease duration (B = -0.34; SE = 0.12; p = 0.007), pain (B = -0.14; SE = 0.06; p = 0.046), intimate relationship (B = -0.07; SE = 0.03; p = 0.046), and emotional health (B = 0.16; SE = 0.06; p = 0.006); factors associated with presenteeism were physical health (B = -0.43; SE = 0.14; p = 0.002) and FACIT (B = -0.87; SE = 0.30; p = 0.005); and factors associated with overall work impairment were pain (B = -0.40; SE = 0.11; p = 0.001) and FACIT-Fatigue (B = -0.74; SE = 0.28; p = 0.010).Conclusion: A poor HRQoL and higher levels of fatigue were associated with a higher percentage of absenteeism, presenteeism, and overall work impairment in SLE patients.

A longitudinal multiethnic study of biomarkers in systemic lupus erythematosus: Launching the GLADEL 2.0 Study Group.

Introduction: After more than 20 years of sustained work, the Latin American Group for the Study of Lupus (GLADEL) has made a significant number of contributions to the field of lupus, not only in the differential role that race/ethnicity plays in its course and outcome but also in several other studies including the beneficial effects of using antimalarials in lupus patients and the development of consensus guidelines for the treatment of lupus in our region. Methods: A new generation of "Lupus Investigators" in more than 40 centers throughout Latin America has been constituted in order to continue the legacy of the investigators of the original cohort and to launch a novel study of serum and urinary biomarkers in patients with systemic lupus erythematosus. Results: So far, we have recruited 807 patients and 631 controls from 42 Latin-American centers including 339 patients with SLE without renal involvement, 202 patients with SLE with prevalent but inactive renal disease, 176 patients with prevalent and active renal disease and 90 patients with incident lupus nephritis. Conclusions: The different methodological aspects of the GLADEL 2.0 cohort are discussed in this manuscript, including the challenges and difficulties of conducting such an ambitious project.

Demographic and Clinical Features of ANCA-Associated Vasculitides in a Peruvian Tertiary Center.

AIM: The aim of this study was to identify the demographic and clinical features of patients with ANCA-associated vasculitides (AAVs) in a Peruvian tertiary referral hospital. METHODS: Medical records of patients with AAV according to classification criteria or diagnosed by an experienced rheumatologist, and covering the period between January 1990 and December 2019, were reviewed. Granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), and renal-limited vasculitis (RLV) were included. Demographic factors (age at diagnosis, sex), disease duration, clinical manifestations (per organ involvement), creatinine level at diagnosis (milligram per deciliter), ANCA status, diagnosis, 2009 Five Factor Score, disease categorization, and treatment were recorded. RESULTS: Two hundred twelve patients were included. Their female-to-male ratio was 1.9:1 (139 [65.6%]/73 [34.4%]), and their mean (SD) age at diagnosis was 59.2 (12.5) years. One hundred fifty-eight patients (74.5%) had MPA, 42 (19.8%) GPA, 7 (3.3%) RLV, and 5 (2.4%) EGPA. Neurological, lung, and renal involvements were the most frequently affected systems. Myeloperoxidase preferentially occurred in MPA (82.5%), whereas proteinase 3 did occur in GPA (79.5%). Microscopic polyangiitis patients were older (61.1 [11.5] years). Female sex predominated in MPA and RLV (2.4:1 and 6:1, respectively), but the opposite was the case for EGPA (1:4). Ear-nose-throat and ocular involvement were more frequent in GPA (both p's < 0.001), and neurological and cardiovascular involvement were more frequent in EGPA (p < 0.001 and p = 0.002, respectively). CONCLUSIONS: This is one of the largest series of AAV patients in Latin America. Overall, female sex predominated. Microscopic polyangiitis was the most frequent AAV, and myeloperoxidase-ANCA was the most frequent antibody in Peruvian AAV population.

Survival in ANCA-Associated Vasculitides in a Peruvian Center: 28 Years of Experience.

AIM: The aim of this study was to identify demographic and clinical risk factors for mortality in patients with antineutrophil cytoplasmic antibodies-associated vasculitides (AAVs) in a Peruvian tertiary referral hospital. METHODS: Medical records of patients with AAV according to classification criteria or diagnosed by an experienced rheumatologist, covering the period between January 1990 and December 2018, were reviewed. Granulomatosis with polyangiitis, microscopic polyangiitis, eosinophilic granulomatosis with polyangiitis, and renal-limited vasculitis were included. Potential predictors of mortality were demographic factors, clinical manifestations, antineutrophil cytoplasmic antibodies status, diagnosis, disease categorization, the 2009 Five Factor Score (FFS), and treatment. Cox regression models were used to determine the risk factors for mortality. Univariable and multivariable analyses using a backward selection method were performed. RESULTS: One hundred ninety-six patients were included; female-to-male ratio was 2:1. The median (interquartile range) age at diagnosis and follow-up were 60.0 (51.0-68.0) and 4.8 (1.3-11.6) years, respectively. One hundred forty-eight patients (75.5%) had microscopic polyangiitis, 37 (18.9%) granulomatosis with polyangiitis, 5 (2.6%) eosinophilic granulomatosis with polyangiitis, and 6 (3.0%) renal-limited vasculitis. Overall survival rates at 1, 5, and 10 years were 83.4%, 68.2%, and 51.7%, respectively. Ocular involvement was protective (hazards ratio [HR], 0.36; 95% confidence interval [CI], 0.17-0.74; p = 0.006), whereas renal (HR, 2.09; 95% CI, 1.33-3.28; p = 0.001) and lung involvement (HR, 2.07; 95% CI, 1.31-3.28; p = 0.002) and the 2009 FFSs were predictive of mortality (2009 FFS = 1: HR, 2.46; 95% CI, 1.50-4.04; p < 0.001; 2009 FFS = 2: HR, 3.07; 95% CI, 1.54-6.10; p = 0.001; 2009 FFS = 3: HR, 13.29; 95% CI, 3.69-47.88; p < 0.001). CONCLUSIONS: Ocular involvement was protective, whereas 2009 FFS ≥ 1 and renal and lung involvement were predictive factors of mortality in Peruvian AAV patients.

Age at diagnosis and health-related quality of life are associated with fatigue in systemic lupus erythematosus patients: Data from the Almenara Lupus Cohort.

OBJECTIVE: To define the factors associated with fatigue in Mestizo patients with Systemic Lupus Erythematosus (SLE). METHODS: This is a cross-sectional study of SLE patients from a single center cohort. Visits were performed every six months. For these analyses, the first visit between October 2017 and December 2018 was included. Demographic and clinical characteristics as well as treatment were recorded at every visit. Fatigue was ascertained with the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-FT), Health-Related Quality of Life (HRQoL) with the LupusQoL, disease activity with the Systemic Lupus Erythematosus Disease Activity Index -2 K (SLEDAI-2K), and damage with the Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology damage index (SDI). Prednisone use was recorded as current daily dose. Immunosuppressive drugs and antimalarial use were recorded as current, past or never. Univariable and multivariable analyses were performed using linear regression models. For the multivariable analyses, model selection followed a backward elimination procedure. RESULTS: Two hundred and twenty-six patients were evaluated. The mean (SD) age at diagnosis was 35.6 (13.1) years, 211 (93.4%) were female; and disease duration was 11.0 (7.3) years. The mean SLEDAI and SDI were 2.4 (3.5) and 1.3 (1.5), respectively. The mean FACIT-FT was 33.1 (10.8). On the multivariable analysis, age at diagnosis and some domains of HRQoL (physical health, emotional health and fatigue) remained associated. CONCLUSIONS: Age at diagnosis is negatively associated with fatigue whereas HRQoL domains like physical health, emotional health and fatigue are positively associated with fatigue.

Reliability of Visual Analog Scale and Numeric Rating Scale for the Assessment of Disease Activity in Systemic Lupus Erythematosus.

OBJECTIVE: To determine the reliability of SLE patients' disease activity measurements. METHODS: This was a cross-sectional study conducted (August 2016-December 2017) at 2 main public Peruvian hospitals, 1 with a comprehensive lupus care program. Patients assessed their disease activity with a visual analog scale (VAS) (0-100 mm) or a numerical rating scale (NRS) (0-4) before and after their physician's (MD's) assessment. Demographic and disease-related characteristics were recorded. Reliability of patients' disease activity before and after MD's assessment was determined using Spearman rank correlation. Factors possibly associated with this variability were examined with Spearman rank correlation and Mann-Whitney U test. RESULTS: Two hundred forty, mostly Mestizo, SLE patients were included; mean (SD) age and disease duration (diagnosis) were 34.9 (12.9) years and 10.1 (7.0) years, respectively. The Mexican version of the Systemic Lupus Erythematosus Disease Activity Index was 1.9 (2.7), and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index was 1.2 (1.5). The correlations between NRS and VAS before and after the MD's assessment were ρ = 0.839; p < 0.001; and ρ = 0.872; p < 0.001, respectively. Visual analog scale and NRS were higher before than after the MD's assessment (VAS 29.3 [26.5] and 26.5 [24.9], p = 0.052; and NRS (1.5 [1.2] and 1.3 [1.1], p = 0.003); only the comprehensive program explained this variability (p = 0.043). The reliability of VAS and NRS was ρ = 0.917 and ρ = 0.861, p < 0.001, before and after for the comprehensive program and ρ = 0.710 and ρ = 0.785, p < 0.001, for before and after for the regular program. CONCLUSIONS: Both VAS an NRS are highly reliable. Patients scored higher before than after their physicians' assessment but that these differences were smaller for the patients in the comprehensive care program than in the regular one.

Peripheral CD4+CD28null T-cells as predictors of damage in systemic lupus erythematosus patients.

OBJECTIVES: To determine whether the CD4+CD28null T-cells subpopulation predicts the occurrence of damage in SLE. METHODS: This longitudinal study was conducted in consecutive SLE patients seen every six months in our Rheumatology Department since 2012. Patients in whom CD4+CD28null T-cells had been measured and who had at least one subsequent visit were included in the study. Survival analyses (univariable and multivariable Cox-regression models) were performed to determine the risk of overall and domain damage (as per the SLICC Damage Index - SDI) as a function of the frequency of this T-cell subpopulation. The multivariable model was adjusted for pertinent confounders. All analyses were performed using SPSS 21.0. RESULTS: One hundred and nineteen patients were evaluated; their mean (SD) age was 43.5 (11.9) years, 113 (95.0%) were female. Disease duration was 7.8 (7.0) years, the SLEDAI 5.3 (4.1) and the SDI 1.0 (1.4). The percentage of CD4+CD28null T-cells was 17.4 (14.0). The mean follow-up was 2.1 (0.8) years, and the mean number of visits per patient 3.5 (1.1). Forty-six (38.7%) patients increase at least one SDI point. In the univariable and multivariable analyses, the percentage of CD4+CD28null predicted the occurrence of lung damage [HR: 1.042 (CI95%: 1.001-1.085); p=0.047 and HR: 1.099 (CI95%1.020-1.184); p=0.013, respectively] but neither the total SDI score nor all other SDI domain scores were predicted by the percentage of CD4+CD28null cells. CONCLUSIONS: In SLE patients, CD4+CD28null T-cells predict the occurrence of new lung damage, independently of other risk factors but not of overall damage or damage on other domains.

A better self-efficacy is predictive of better health-related quality of life (HRQoL) in patients with systemic lupus erythematosus: data from the Almenara Lupus Cohort.

OBJECTIVE: To determine the possible predictive value of self-efficacy on health-related quality of life (HRQoL) in patients with SLE. METHODS: Patients with SLE from the Almenara Lupus Cohort were included. Self-efficacy was ascertained with the six domains from the Patient-Reported Outcomes Measurement Information System (PROMIS) self-efficacy for managing chronic conditions. For PROMIS domains, a score of 50 is the average for a clinical population (people with a chronic condition), a higher score indicates that the respondent has greater self-efficacy. HRQoL was ascertained with the physical and mental component summary (PCS and MCS) measures of the Short-Form 36 (SF-36). Generalised estimating equations were performed, using as outcome the PCS or MCS in the subsequent visit, and the self-efficacy domain in the previous visit; multivariable models were adjusted for possible confounders. The confounders were measured in the same visit as the self-efficacy domain. RESULTS: Two-hundred and nine patients for a total of 564 visits were included; 194 (92.8%) patients were women and mean age at diagnosis was 36.4 (14.0) years. In the multivariable models, a better PCS was predicted by a better self-efficacy for managing symptoms, managing medications and treatments and managing social interactions and general self-efficacy; a better MCS was predicted by a better self-efficacy for managing daily activities, managing symptoms, managing medications and treatments and managing social interactions. CONCLUSION: A better self-efficacy is predictive of subsequent better HRQoL, even after adjustment for possible confounders. These results should encourage clinicians to develop strategies to improve self-efficacy in patients with SLE.
