ABSTRACT

Management of systemic lupus erythematosus patients is challenging because of disease heterogeneity. Although treatment of renal nephritis is more standardized, treating non-renal lupus activity remains controversial. Our objective was to identify non-renal, non-neurologic persistent active systemic lupus erythematosus patients in our cohort and described therapeutic behaviors in them. All systemic lupus erythematosus patients (American College of Rheumatology and/or Systemic Lupus Erythematosus International Collaborating Clinics criteria) seen at a university hospital between 2000 and 2017 were included and electronic medical records manually reviewed. Persistent lupus activity was defined as a patient with a Systemic Lupus Erythematosus Disease Activity Index score ≥ 6 (without renal and central nervous system manifestations) despite being on a stable treatment regimen for ≥ 30 days. Stable treatment could include prednisone alone (7.5-40 mg/d) or combined with antimalarial drugs and immunosuppressant therapies. A total of 257 lupus patients were included, 230 females (89.5%, 95% confidence interval 85.1-92.7), mean age at diagnosis 29.9 years (SD 16.4). After a median cohort follow-up of 5.7 years (interquartile range 2.4-10.2), 14 patients (5.4%, 95% confidence interval 3.2-9.0) showed persistent non-renal non neurologic lupus activity, with a median disease duration of 11.3 years (interquartile range 3.6-19.4). At that time, 12/14 (85.7 %, 95% confidence interval 52.6-97.0%) had low complement and 11/14 (78.6 %, 95% confidence interval 46.5-93.9%) had positive antiDNA antibodies. The main reasons for being refractory were mucocutaneous disease (50%, 95% confidence interval 23.5-76.5) and arthritis (42.9%, 95% confidence interval 18.5-71.2). Therapeutic choices after being refractory were: only increasing corticosteroid dose in one patient, starting rituximab in four, belimumab in eight, and in one mycophenolate and rituximab; with good response in all of them. In conclusion, 5.4% of systemic lupus erythematosus patients in our cohort were considered to have non-renal non neurologic persistent lupus activity, with mucocutaneous and arthritis the main manifestations. In total, 92.8% of these patients started a biologic treatment at this point (rituximab or belimumab).

ABSTRACT

AIM: The aim of this study was to identify factors predictive of serious infections over time in patients with systemic lupus erythematosus (SLE). METHODS: A multi-ethnic, multi-national Latin American SLE cohort was studied. Serious infection was defined as one that required hospitalization, occurred during a hospitalization or led to death. Potential predictors included were sociodemographic factors, clinical manifestations (per organ involved, lymphopenia and leukopenia, independently) and previous infections at baseline. Disease activity (SLEDAI), damage (SLICC/ACR Damage Index), non-serious infections, glucocorticoids, antimalarials (users and non-users), and immunosuppressive drugs use; the last six variables were examined as time-dependent covariates. Cox regression models were used to evaluate the predictors of serious infections using a backward elimination procedure. Univariable and multivariable analyses were performed. RESULTS: Of the 1243 patients included, 1116 (89.8%) were female. The median (interquartile range) age at diagnosis and follow-up time were 27 (20-37) years and 47.8 (17.9-68.6) months, respectively. The incidence rate of serious infections was 3.8 cases per 100 person-years. Antimalarial use (hazard ratio: 0.69; 95% confidence interval (CI): 0.48-0.99; p = 0.0440) was protective, while doses of prednisone >15 and ≤60 mg/day (hazard ratio: 4.18; 95 %CI: 1.69-10.31; p = 0.0019) and >60 mg/day (hazard ratio: 4.71; 95% CI: 1.35-16.49; p = 0.0153), use of methylprednisolone pulses (hazard ratio: 1.53; 95% CI: 1.10-2.13; p = 0.0124), increase in disease activity (hazard ratio: 1.03; 95% CI: 1.01-1.04; p = 0.0016) and damage accrual (hazard ratio: 1.22; 95% CI: 1.11-1.34; p < 0.0001) were predictive factors of serious infections. CONCLUSIONS: Over time, prednisone doses higher than 15 mg/day, use of methylprednisolone pulses, increase in disease activity and damage accrual were predictive of infections, whereas antimalarial use was protective against them in SLE patients.

ABSTRACT

Objetivo: Actualizar los resultados del registro BIOBADASAR sobre seguridad, duración y causas de interrupción del tratamiento luego de 8 años de seguimiento. Métodos: BIOBADASAR es un registro de seguridad de terapias biológicas establecido por la Sociedad Argentina de Reumatología. Se presenta la descripción de BIOBADASAR 3.0, una cohorte compuesta por 53 centros de Argentina seguidos prospectivamente desde agosto de 2010 hasta enero de 2018. Resultados: Se registraron 4656 pacientes, 6234 tratamientos [3765 casos (terapia con biológicos) y 2469 controles (terapia no biológicos)]. Se interrumpió el tratamiento en el 44,6% en los casos vs. 27,9% en los controles. Causa principal de discontinuación fue por ineficacia (40% casos vs. 32% controles). Se presentaron 3154 eventos adversos (2230 en casos vs. 924 en controles), de los cuales el 13,6% fueron graves (9,8% en casos y 3,7% en controles). El evento adverso (EA) más frecuente en ambos grupos fueron las infecciones (43,56% en casos vs. 34,31% en los controles, RR: 3,42; IC 95%: 3,02-3,88), y de ellas las de vías aéreas superiores (14,5%). Las neoplasias se presentaron en 78 casos vs. 45 en controles (RR: 1,98; IC 95%: 1,37-2,86). Conclusiones: En este sexto reporte no se observan tendencias diferentes sobre seguridad, duración y causas de interrupción del tratamiento respecto a informes previos. Las infecciones fueron el principal EA y la ineficacia, seguido por EA y la pérdida de pacientes las principales causas de suspensión del tratamiento. El advenimiento de nuevos agentes biológicos y la necesidad de control en seguridad a largo plazo, fortalece el uso de este tipo de registro.


Objective: Update the results of the BIOBADASAR registry on safety, duration and causes of treatment interruption after 8 years of follow-up. Methods: BIOBADASAR is a safety record of biological therapies established by the Argentine Society of Rheumatology. The description of BIOBADASAR 3.0 is presented, a cohort of 53 centers in Argentina followed prospectively from August 2010 to January 2018. Results: 4656 patients were registered, 6234 treatments [3765 cases (therapy with biologicals) and 2469 controls (non-biological therapy)]. Treatment was interrupted in 44.6% in cases vs. 27.9% in controls. Main cause of discontinuation was due to inefficiency (40% cases vs. 32% controls). There were 3154 adverse events (2230 in cases vs. 924 in controls), of which 13.6% were tombs (9.8% in cases and 3.7% in controls). The most frequent adverse event (AE) in both groups were infections (43.56% in cases vs. 34.31% in controls, RR: 3.42, 95% CI: 3.02-3.88), and the upper airway pathways (14.5%). Neoplasms were published in 78 cases versus 45 controls (RR: 1.98, 95% CI: 1.37-2.86). Conclusions: In this article, there are no different trends regarding safety, duration and causes of interruption of treatment compared to previous reports. Infections were the main causes of treatment discontinuation. The advent of new biological agents and the need for control over long-term security, strengthens the use of this type of registration.

ABSTRACT

OBJECTIVE: The objective of this report is to determine the impact of remission and low disease activity state (LDAS) on damage accrual and mortality in systemic lupus erythematosus (SLE) patients. PATIENTS AND METHODS: Visits from the Lupus in Minority populations: Nature vs. Nurture (LUMINA) cohort were categorized into remission (Systemic Lupus Activity Measure (SLAM) score = 0 and prednisone ≤ 5 mg/day and no immunosuppressants), LDAS ((not on remission), SLAM score ≤ 3, prednisone ≤ 7.5 mg/day, no immunosuppressants), or neither: active. Remission and LDAS visits were combined because of the relatively small number of remission visits. Their impact on damage accrual and mortality were examined by Poisson and logistic multivariable regressions adjusting for variables known to affect these outcomes. RESULTS: A total of 3879 visits for 558 patients (28% Caucasian, 37% African descent, 35% Hispanic) were studied. These visits corresponded to 71 in remission, 585 in LDAS, and 3223 active. The longer the percentage of time the patients were in remission/LDAS, the less damage accrual observed (rate ratio 0.1773 (95% confidence interval (CI) 0.1216 to 0.2584) p < 0.0001). A trend was observed in terms of mortality although statistical significance was not reached (odds ratio 0.303 (95% CI 0.063 to 1.456), p = 0.1360). CONCLUSIONS: The longer the patient's state on Remission/LDAS, the less damage accrual that occurs. The protective effect on mortality was not statistically significant.

ABSTRACT

OBJECTIVES: The objective of this study was to examine whether early discoid lupus erythematosus (DLE) would be a protective factor for further lupus nephritis in patients with systemic lupus erythematosus (SLE). METHODS: We studied SLE patients from GLADEL, an inception longitudinal cohort from nine Latin American countries. The main predictor was DLE onset, which was defined as physician-documented DLE at SLE diagnosis. The outcome was time from the diagnosis of SLE to new lupus nephritis. Univariate and multivariate survival analyses were conducted to examine the association of DLE onset with time to lupus nephritis. RESULTS: Among 845 GLADEL patients, 204 (24.1%) developed lupus nephritis after SLE diagnosis. Of them, 10 (4.9%) had DLE onset, compared to 83 (12.9%) in the group of 641 patients that remained free of lupus nephritis (hazard ratio 0.39; P = 0.0033). The cumulative proportion of lupus nephritis at 1 and 5 years since SLE diagnosis was 6% and 14%, respectively, in the DLE onset group, compared to 14% and 29% in those without DLE (P = 0.0023). DLE onset was independently associated with a lower risk of lupus nephritis, after controlling for sociodemographic factors and disease severity at diagnosis (hazard ratio 0.38; 95% confidence interval 0.20-0.71). CONCLUSIONS: Our data indicate that DLE onset reduces the risk of further lupus nephritis in patients with SLE, independently of other factors such as age, ethnicity, disease activity, and organ damage. These findings have relevant prognosis implications for SLE patients and their clinicians. Further studies are warranted to unravel the biological and environmental pathways associated with the protective role of DLE against renal disease in patients with SLE.

ABSTRACT

In a previous systematic literature search, we demonstrated that the frequencies of antiphospholipid antibodies (aPL) in general-population patients with pregnancy morbidity (PM), deep vein thrombosis (DVT), myocardial infarction (MI), and stroke (ST) are 6%, 10%, 11%, and 14%. To determine the association between aPL and clinical outcomes, we conducted a follow-up analysis of the 120 studies included in the original paper. Based on the analysis of 81 studies, a significant difference in the frequency of aPL criteria tests between patients and controls emerged considering all the outcomes together (10% versus 3%). In particular, a significant difference was reported for overall PM, pregnancy loss (PrL), late PrL, severe preeclampsia (PEC), ST, MI, and DVT. No difference emerged for early PrL, intrauterine growth restriction (IUGR), PEC, eclampsia (EC), and HELLP. A positive association was found in more than half of the studies for overall PrL, severe PEC, HELLP, ST, MI, and DVT and in less than half for early and late PrL, PEC, EC, and IUGR. The positive association between aPL and clinical outcomes included in the antiphospholipid syndrome classification criteria is not supported by every study, being particularly inconsistent for early PL, IUGR, PEC, EC, and HELLP.

ABSTRACT

The need for comprehensive published epidemiologic and clinical data from Latin American systemic lupus erythematosus (SLE) patients motivated the late Dr Alarcón-Segovia and other Latin American professionals taking care of these patients to spearhead the creation of the G: rupo L: atino A: mericano D: e E: studio del L: upus (GLADEL) cohort in 1997. This inception cohort recruited a total of 1480 multiethnic (Mestizo, African-Latin American (ALA), Caucasian and other) SLE patients diagnosed within two years from the time of enrollment from 34 Latin American centers with expertise in the diagnosis and management of this disease. In addition to the initial 2004 description of the cohort, GLADEL has contributed to improving our knowledge about the course and outcome of lupus in patients from this part of the Americas. The major findings from this cohort are highlighted in this review. They have had important clinical implications for the adequate care of SLE patients both in Latin America and worldwide where these patients may have emigrated.

ABSTRACT

OBJECTIVES: To assess the prevalence of the main causes of morbi-mortality in the antiphospholipid syndrome (APS) during a 10-year-follow-up period and to compare the frequency of early manifestations with those that appeared later. METHODS: In 1999, we started an observational study of 1000 APS patients from 13 European countries. All had medical histories documented when entered into the study and were followed prospectively during the ensuing 10 years. RESULTS: 53.1% of the patients had primary APS, 36.2% had APS associated with systemic lupus erythematosus and 10.7% APS associated with other diseases. Thrombotic events appeared in 166 (16.6%) patients during the first 5-year period and in 115 (14.4%) during the second 5-year period. The most common events were strokes, transient ischaemic attacks, deep vein thromboses and pulmonary embolism. 127 (15.5%) women became pregnant (188 pregnancies) and 72.9% of pregnancies succeeded in having one or more live births. The most common obstetric complication was early pregnancy loss (16.5% of the pregnancies). Intrauterine growth restriction (26.3% of the total live births) and prematurity (48.2%) were the most frequent fetal morbidities. 93 (9.3%) patients died and the most frequent causes of death were severe thrombosis (36.5%) and infections (26.9%). Nine (0.9%) cases of catastrophic APS occurred and 5 (55.6%) of them died. The survival probability at 10 years was 90.7%. CONCLUSIONS: Patients with APS still develop significant morbidity and mortality despite current treatment. It is imperative to increase the efforts in determining optimal prognostic markers and therapeutic measures to prevent these complications.

ABSTRACT

OBJECTIVES: The objective of this paper is to assess the predictors of time-to-lupus renal disease in Latin American patients. METHODS: Systemic lupus erythematosus (SLE) patients (n = 1480) from Grupo Latino Americano De Estudio de Lupus (GLADEL's) longitudinal inception cohort were studied. Endpoint was ACR renal criterion development after SLE diagnosis (prevalent cases excluded). Renal disease predictors were examined by univariable and multivariable Cox proportional hazards regression analyses. Antimalarials were considered time dependent in alternative analyses. RESULTS: Of the entire cohort, 265 patients (17.9%) developed renal disease after entering the cohort. Of them, 88 (33.2%) developed persistent proteinuria, 44 (16.6%) cellular casts and 133 (50.2%) both; 233 patients (87.9%) were women; mean (± SD) age at diagnosis was 28.0 (11.9) years; 12.2% were African-Latin Americans, 42.5% Mestizos, and 45.3% Caucasians (p = 0.0016). Mestizo ethnicity (HR 1.61, 95% CI 1.19-2.17), hypertension (HR 3.99, 95% CI 3.02-5.26) and SLEDAI at diagnosis (HR 1.04, 95% CI 1.01-1.06) were associated with a shorter time-to-renal disease occurrence; antimalarial use (HR 0.57, 95% CI 0.43-0.77), older age at onset (HR 0.90, 95% CI 0.85-0.95, for every five years) and photosensitivity (HR 0.74, 95% CI 0.56-0.98) were associated with a longer time. Alternative model results were consistent with the antimalarial protective effect (HR 0.70, 95% CI 0.50-0.99). CONCLUSIONS: Our data strongly support the fact that Mestizo patients are at increased risk of developing renal disease early while antimalarials seem to delay the appearance of this SLE manifestation. These data have important implications for the treatment of these patients regardless of their geographic location.

ABSTRACT

OBJECTIVE: The objective of this paper is to examine the role of place of residency in the expression and outcomes of systemic lupus erythematosus (SLE) in a multi-ethnic Latin American cohort. PATIENTS AND METHODS: SLE patients (< two years of diagnosis) from 34 centers constitute this cohort. Residency was dichotomized into rural and urban, cut-off: 10,000 inhabitants. Socio-demographic, clinical/laboratory and mortality rates were compared between them using descriptive tests. The influence of place of residency on disease activity at diagnosis and renal disease was examined by multivariable regression analyses. RESULTS: Of 1426 patients, 122 (8.6%) were rural residents. Their median ages (onset, diagnosis) were 23.5 and 25.5 years; 85 (69.7%) patients were Mestizos, 28 (22.9%) Caucasians and 9 (7.4%) were African-Latin Americans. Rural residents were more frequently younger at diagnosis, Mestizo and uninsured; they also had fewer years of education and lower socioeconomic status, exhibited hypertension and renal disease more frequently, and had higher levels of disease activity at diagnosis; they used methotrexate, cyclophosphamide pulses and hemodialysis more frequently than urban patients. Disease activity over time, renal damage, overall damage and the proportion of deceased patients were comparable in rural and urban patients. In multivariable analyses, rural residency was associated with high levels of disease activity at diagnosis (OR 1.65, 95% CI 1.06-2.57) and renal disease occurrence (OR 1.77, 95% CI 1.00-3.11). CONCLUSIONS: Rural residency associates with Mestizo ethnicity, lower socioeconomic status and renal disease occurrence. It also plays a role in disease activity at diagnosis and kidney involvement but not on the other end-points examined.

ABSTRACT

BACKGROUND: Nephropathy associated with antiphospholipid antibodies (aPL) has been proposed as a risk factor of worse renal prognosis in patients with systemic lupus erythematosus (SLE). The purpose of the current study was to evaluate the prevalence of aPL-associated nephropathy (aPLN) among patients with lupus nephritis and to describe their functional renal outcome. METHODS: A total of 79 renal biopsies from 77 patients followed at the Hospital Clinic, Spain were analysed. Each renal biopsy was evaluated by a pathologist who was blinded to the aPL status. Thrombotic microangiopathy (TMA), fibrous intimal hyperplasia (FIH), fibrocellular arterial occlusion (FAO), focal cortical atrophy (FCA), and tubular thyroidization as lesions suggestive of aPLN were identified. RESULTS: aPLN was found in nine (11.4%) biopsies. TMA was found in three (33.3%) cases whereas chronic aPLN, represented by FIH and FCA, was found in four (44.4%) and three (33.3%) cases, respectively. A significant association between the presence of aPL and aPLN was found (p = 0.003). Patients with lupus anticoagulant (LA) plus IgG anticardiolipin antibodies (aCL) showed an increased prevalence of aPLN (OR: 3.61, 95% CI 1.28-5.14; p = 0.002). Creatinine levels were significantly increased in patients with aPLN compared with those with aPL without aPLN (p = 0.038). However, no significant difference in complete remission, partial remission, not response, and established renal damage between groups was observed at the end of follow-up. CONCLUSIONS: The aPL have an important role in the pathogenesis of renal lesions in SLE patients. Prospective studies are needed to address the role of aPLN in the long-term outcome of SLE patients with positive aPL.

ABSTRACT

OBJECTIVE: To examine the predictors of time to premature gonadal failure (PGF) in patients with systemic lupus erythematosus from LUMINA, a multiethnic US cohort. METHODS: PGF was defined according to the SLICC Damage Index (SDI). Factors associated with time to PGF occurrence were examined by univariable and multivariable Cox proportional hazards regression analyses: three models according to cyclophosphamide use, at T0 (model 1), over time (model 2) and the total number of intravenous pulses (model 3). RESULTS: Thirty-seven of 316 women (11.7%) developed PGF (19 Texan-Hispanics, 14 African-Americans, four Caucasians and no Puerto Rican-Hispanics). By multivariable analyses, older age at T0 (hazards ratio (HR) = 1.10-1.14; 95% CI 1.02-1.05 to 1.19-1.23) and disease activity (Systemic Lupus Activity Measure-Revised) in all models (HR = 1.22-1.24; 95% CI 1.10-1.12 to 1.35-1.37), Texan-Hispanic ethnicity in models 2 and 3 (HR = 4.06-5.07; 95% CI 1.03-1.25 to 15.94-20.47) and cyclophosphamide use in models 1 and 3 (1-6 pulses) (HR = 4.01-4.65; 95% CI 1.55-1.68 to 9.56-13.94) were predictors of a shorter time to PGF. CONCLUSIONS: Disease activity and Texan-Hispanic ethnicity emerged as predictors of a shorter time to PGF while the associations with cyclophosphamide use and older age were confirmed. Furthermore, cyclophosphamide induction therapy emerged as an important determinant of PGF.
