    Factors predictive of high disease activity early in the course of SLE in patients from a Latin-American cohort
    (W.B. Saunders, 2017) Pimentel-Quiroz, V.R.; Ugarte-Gil, M.F.; Pons-Estel, G.J.; Soriano, E.R.; Saurit V.; Sato, E.I.; Lavras Costallat, L.T.; Molina J.F.; Iglesias-Gamarra, A.; Reyes-Llerena, G.; Neira O.J.; Barile L.A.; Silveira, L.H.; Segami, M.I.; Chacón-Díaz, R.; Wojdyla, D.; Alarcón, G.S.; Pons-Estel, B.A.
    Aims: To determine the factors predictive of disease activity early in the course of SLE (baseline visit). Methods: Patients from GLADEL, a multi-national, multi-ethnic, Latin-American lupus cohort were included. Disease activity was evaluated at baseline with the SLEDAI score. Demographic characteristics (age at diagnosis, gender, ethnicity, marital status, educational level, medical coverage and socioeconomic status) were assessed. Disease duration was defined as the time between the fourth ACR criterion and baseline. Time to criteria accrual was defined as the interval between the first and fourth ACR criterion. Use of glucocorticoids was recorded as the highest dose received before the baseline visit. Antimalarials and immunosuppressive drugs were recorded as use or not use. Univariable and multivariable analysis were performed. Model selection was based on backward elimination. Results: One thousand two hundred sixty-eight patients were included; 1136 (89.6%) of them were female. Mean age at diagnosis was 29.2 (SD: 12.3) years. Five hundred sixty-five (44.6%) were Mestizo, 539 (42.5%) were Caucasians and 164 (12.9%) were African-Latin-Americans. The mean SLEDAI at baseline was 10.9 (SD: 8.4). Longer time between first and fourth ACR criterion, medical coverage, a dose of prednisone between 15 and 60. mg/d, and the use of antimalarials were factors protective of disease activity, while Mestizo and African-Latin-American ethnicities were predictive factors. Conclusions: Mestizo and African-Latin-American ethnicities were predictive whereas antimalarial use, medical coverage, and longer time to criteria accrual were protective of higher disease activity early in the disease course. © 2017 Elsevier Inc.

    The number of flares patients experience impacts on damage accrual in systemic lupus erythematosus: Data from a multiethnic Latin American cohort
    (BMJ Publishing Group, 2015) Ugarte-Gil, M.F.; Acevedo-Vásquez, E.; Alarcón, G.S.; Pastor-Asurza, C.A.; Alfaro-Lozano, J.L.; Cucho-Venegas, J.M.; Segami, M.I.; Wojdyla, D.; Soriano, E.R.; Drenkard, C.; Brenol, J.C.; De Oliveira E Silva Montandon, A.C.; Lavras Costallat, L.T.; Massardo, L.; Molina-Restrepo, J.F.; Guibert-Toledano, M.; Silveira, L.H.; Amigo, M.C.; Barile-Fabris, L.A.; Chacón-Díaz, R.; Esteva-Spinetti, M.H.; Pons-Estel, G.J.; McGwin, G. Jr.; Pons-Estel, B.A.
    Purpose: To determine the association between the number of flares systemic lupus erythematosus (SLE) patients experience and damage accrual, independently of other known risk factors. Methods: SLE patients (34 centres, nine Latin American countries) with a recent diagnosis (≤2 years) and ≥3 evaluations were studied. Disease activity was ascertained with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and damage with the SLICC/ACR Damage Index (SDI). Flare was defined as an increase ≥4 points in the SLEDAI between two study visits. An ambidirectional case- crossover design was used to determine the association between the number of flares and damage accrual. Results: 901 patients were eligible for the study; 500 of them (55.5%) experienced at least one flare, being the mean number of flares 0.9 (SD: 1.0). 574 intervals from 251 patients were included in the case-crossover design since they have case and control intervals, whereas, the remaining patients did not. Their mean age at diagnosis was 27.9 years (SD: 11.1), 213 (84.9%) were women. The mean baseline SDI and SLEDAI were 1.3 (1.3) and 13.6 (8.1), respectively. Other features were comparable to those of the entire sample. After adjusting for possible confounding variables, the number of flares, regardless of their severity, was associated with damage accrual (SDI) OR 2.05, 95% CI 1.43 to 2.94, p<0.001 (OR 2.62, 95% CI 1.31 to 5.24, p=0.006 for severe and OR 1.91, 95% CI 1.28 to 2.83, p=0.001 for mild-moderate). Conclusions: The number of flares patients experience, regardless of their severity, increases the risk of damage accrual, independently of other known risk factors. © 2015, BMJ Publishing Group.
