RESUMEN
Introducción: la disfunción sexual (DS) es la alteración en una o varias de las fases de la actividad sexual. Puede culminar en frustración, dolor y disminución de la frecuencia de las relaciones sexuales. Objetivos: determinar la frecuencia de DS y analizar los factores asociados en pacientes con lupus eritematoso sistémico (LES). Materiales y métodos: se realizó un estudio de corte transversal. Se incluyeron pacientes femeninas con LES, entre 18 y 50 años, se excluyeron aquellas con síndrome de Sjögren, menopausia, depresión severa y analfabetas. Se evaluaron variables demográficas y de la enfermedad. Se aplicó la escala Depression Anxiety Stress Scale (DASS-21) y el Índice de Función Sexual Femenina (Female Sexual Function Index, FSFI). Se comparó con un grupo control sano. Resultados: se evaluaron 60 mujeres con LES y 63 controles. La prevalencia de DS en LES fue de 71,7% y hubo diferencias significativas en todos los dominios de la función sexual. El score total del FSFI en pacientes con LES fue menor al comparar con los controles. Según la escala DASS-21, estrés, ansiedad y depresión se observaron en al menos la mitad de mujeres lúpicas, sin embargo, no se encontró asociación entre estas variables y DS. Conclusiones: la prevalencia de DS en pacientes con LES fue elevada. Depresión, ansiedad y estrés no fueron determinantes en la presencia de DS.
Introduction: sexual dysfunction is the alteration in one or several phases of sexual activity. It can culminate in frustration, pain and a decrease in the frequency of sexual intercourse. Objectives: determine the frequency of sexual dysfunction and analyze associated factors in patients with SLE. Materials and methods: a descriptive cross-sectional study was conducted. We included patients with SLE, between 18 and 50 years of age, Secondary Sjogren's syndrome, menopause, severe depression and illiterate patients were excluded. Demographic and disease-related variables were studied. The Depression Anxiety Stress Scale (DASS-21), and the Female Sexual Function Index (FSFI) were applied. Results: sixty women with SLE and 63 controls were evaluated. The prevalence of SD in SLE was 71.7% and there were significant differences in all domains of sexual function. The total FSFI score in patients with SLE was lower when compared to controls. According to the DASS-21 scale, stress, anxiety and depression were observed in at least half of lupus women, however no association was found between these variables and SD. Conclusions: the prevalence of SD in patients with SLE was high. Depression, Anxiety, and Stress were not determinants in the presence of SD.

OBJECTIVE: The aim of this study was to determine the prevalence of depression among rheumatoid arthritis (RA) Argentinean patients and its association with sociodemographic and clinical factors. METHODS: We performed a cross-sectional study of consecutive adults with RA. Sociodemographic data, comorbidities, RA disease activity, and current treatment were assessed. The following instruments were used to evaluate quality of life (EQ-5D-3 L [EURO Quality 5-dimension 3 lines], QOL-RA [Quality of Life-Rheumatoid Arthritis]), functional capacity (HAQ-A [Health Assessment Questionnaire-Argentinean version]), and depression (PHQ-9 [Patient Health Questionnaire 9]; scores 5-9: mild, 10-14: moderate, 15-19: moderate-severe, and ≥20: severe depression, a cutoff value ≥10 is diagnostic of major depression). RESULTS: Two hundred fifty-eight patients were included, with a median disease duration of 9 years (interquartile range, 3.6-16.7 years). The m PHQ-9 score was 6 (interquartile range, 2-12.3 years). The prevalence of major depression was 33.8%. The frequency of mild, moderate, moderate/severe, and severe depression was 66 (25.6%), 42 (16.3%), 27 (10.5%), and 18 (7%), respectively. Patients with major depression had worse functional capacity (HAQ-A: mean ± SD, 1.6 ± 0.8 vs. 0.7 ± 0.7; p < 0.0001), poorer quality of life (QOL-RA: mean ± SD, 5.4 ± 1.8 vs. 7.3 ± 1.6; p < 0.0001), greater pain (visual analog scale: mean ± SD, 56.2 ± 27.5 mm vs. 33.4 ± 25.7 mm; p < 0.0001), higher disease activity (Disease Activity Score in 28 joints: mean ± SD, 4.3 ± 1.4 vs. 3.3 ± 1.3; p < 0.0001), higher frequency of comorbidities (67% vs. 33%; p = 0.017), and lower frequency of physical activity (22% vs. 35%; p = 0.032). In the multivariate analysis, patients with moderate and severe depression had worse functional capacity (odds ratio, 2.1; 95% confidence interval, 1.6-4.3; p < 0.0001) and quality of life (odds ratio, 0.7; 95% confidence interval, 0.5-0.8; p < 0.0001), independently of disease activity. CONCLUSIONS: A third of RA patients in this Argentinean cohort had major depression. In those patients, depression was associated with worst functional capacity and quality of life.

The aim of this study was to determine the prevalence and incidence of Systemic Lupus Erythematosus (SLE) in Tucumán, Argentina. METHODS: The study included inpatient and outpatient charts from four public hospitals and private practice rheumatology clinics, all of them members of the Tucumán Rheumatology Society. Patients older than 16 years with diagnosis of SLE between January 2005 and December 2012 were included. Prevalence and annual incidence were calculated as the number of cases per 100.000 inhabitants during the period 2005 to 2012. RESULTS: Three hundred fifty-three patients were identified. The mean age at diagnosis was 30.5 ± 11.7 years, 93.5% women, 83% mestizos. Prevalence was 24.3 cases/100.000 inhabitants (CI 95% 22.6-28.8) and age-adjusted (≥16 years) of 34.9 cases/100.000 inhabitants (CI 95% 32.8-41.1). The annual incidence in 2005 was 1.8 cases/100.000 inhabitants (95% CI 1-2.9) and 2012 of 4.2 cases/100.000 inhabitants (95% CI 2.9-5.8). Mortality was 9.1%, with infections being the most frequent cause (14/32). CONCLUSION: The prevalence of SLE in the province of Tucumán was 34.9 cases/100.000 inhabitants.

To validate the Quality of Life-Rheumatoid Arthritis Scale II (QOL-RA II) in an Argentinean cohort of patients with rheumatoid arthritis (RA). Patients ≥ 18 years old, with a diagnosis of RA according to ACR-EULAR 2010 criteria, were included in a cross-sectional study. Sociodemographic data, comorbidities, RA characteristics, disease activity, and current treatment were registered. Questionnaires were administered, including EQ-5D-3 L, QOL-RA II, HAQ-A, and PHQ-9. The QOL-RA II was re-administered in 20 patients to evaluate reproducibility. Four hundred and thirty patients were included. Median QOL-RA was 6.6 (IQR 5.3-8). Mean time to complete it was 1.7 ± 0.57 min and to calculate it was 12 ± 1.7 s. It showed very good reliability (Cronbach's alpha 0.97), reproducibility (ICC, 0.96), and good correlation between the different items and the total questionnaire, without evidence of redundancy. Besides, QOL-RA II presented good correlation with EQ-5D-3L (Rho, 0.6) and moderate with DAS28 (Rho, 0.38), and CDAI (Rho, 0.46). Worse quality of life was observed in patients not doing physical activity, unemployed, and current smokers. Patients with higher disease activity had a significant poorer quality of life. Adjusting by age, sex and disease duration, unemployment, higher disease activity, disability, and the presence of depression were independently associated to worse quality of life. QOL-RA II demonstrated good construct validity, reproducibility, and reliability. It was easy to complete and calculate and does not require a license for its use, thus making it the optimal tool for assessing the quality of life in Spanish-speaking patients with RA. Key Points ⢠The evaluation of quality of life is very important in patients with Rheumatoid Arthritis. ⢠Most of the questionnaires used to assess the quality of life require a license to use. ⢠QOL-RA II is a valid and simple questionnaire to evaluate the quality of life of patients with RA and does not require a license for its use.

La depresión es una de las comorbilidades más frecuentemente reportadas en pacientes con Artritis Reumatoidea (AR). Su presencia se asocia a mayores costos de salud, mayor mortalidad y reduce las probabilidades de alcanzar una buena respuesta al tratamiento. Objetivo: Evaluar la prevalencia de depresión en pacientes argentinos con AR y establecer su relación con diferentes factores sociodemográficos y clínicos. Material y métodos: Se incluyeron pacientes ≥18 años de edad, con diagnóstico de AR según criterios ACR-EULAR 2010. Se consignaron datos sociodemográficos, comorbilidades, características clínicas, actividad de la enfermedad y tratamiento actual. Se administraron los cuestionarios EQ-5D-3L, QOL-RA, HAQ-A y PHQ-9. Los valores de PHQ-9 de 5-9, 10-14, 15-19 y ≥20 determinan la presencia de depresión leve, moderada, moderada/severa y severa, respectivamente y un valor de corte ≥10, depresión mayor. Análisis estadístico: Test T de Student, ANOVA y Chi². Regresión lineal múltiple. Resultados: Se incluyeron 258 pacientes, con un tiempo mediano (m) de evolución de la enfermedad de 9 años (RIC 3,6-16,7). La m de depresión valorada por PHQ-9 de 6 (RIC 2-12,5). La prevalencia de depresión mayor fue de 33,8%. Sesenta y seis (25,6%), 42 (16,3%), 27 (10,5%) y 18 (7%) pacientes presentaron depresión leve, moderada, moderada/severa y severa, respectivamente. Los pacientes con depresión mayor mostraron menor capacidad funcional (HAQ-A X1,6±0,8 vs X0,7±0,7, p <0,0001), peor calidad de vida (QOL-RA X5,4±1,8 vs X7,3±1,6, p <0,0001), más dolor (EVN X56,2±27,5 mm vs X33,4±25,7 mm, p <0,0001), mayor actividad de la enfermedad (DAS28-ERS X4,3±1,4 vs X3,3±1,3, p <0,0001), mayor frecuencia de desempleo (71% vs 29%, p=0,015 ) y de comorbilidades (67% vs 33%, p=0,017) y menor frecuencia de actividad física (22% vs 35%, p=0,032). En el análisis multivariado, peor capacidad funcional (OR: 2,1, IC 95%: 1,6-4,3, p <0,0001) y calidad de vida (OR: 0,7, IC 95%: 0,5-0,8, p <0,0001) se asociaron independientemente a la presencia de depresión mayor. Conclusiones: La prevalencia de depresión mayor medida por PHQ-9 en esta cohorte argentina de pacientes con AR fue de 33,8%. La presencia de depresión tiene un impacto negativo sobre la capacidad funcional y la calidad de vida de estos pacientes, independientemente de la actividad de la enfermedad.
Depression is one of the most frequent comorbidity in patients with Rheumatoid Arthritis (RA). It's presence is associated with higher healthcare costs, mortality rate and reduced odds of achieving a good treatment response. Objective: To determine the prevalence of depression in Argentinean patients with RA and to establish its relationship with different sociodemographic and clinical factors. Material and methods: Consecutive patients ≥18 years old, with a diagnosis of RA according to ACR-EULAR 2010 criteria were included. Sociodemographic data, comorbidities, RA characteristics, disease activity and current treatment were registered. Questionnaires were administered: EQ-5D-3L, QOL-RA, HAQ-A and PHQ-9. PHQ-9 scores of 5-9, 10-14, 15-19, ≥20 represent mild, moderate, moderate/severe and severe depression, respectively and a cut-off value ≥10, major depression. Statistical analysis: Student's T, ANOVA and Chi² tests. Multiple logistic regression. Results: 258 patients were included, with a median (m) disease duration of 9 years (IQR 3.6-16.7). The m PHQ-9 score was 6 (IQR 2-12.3). The prevalence of major depression was 33.8%. 66 (25.6%), 42 (16.3%), 27 (10.5%) and 18 (7%) patients presented mild, moderate, moderate/severe and severe depression, respectively. Patients with mayor depression had worse functional capacity (HAQ-A X 1.6±0.8 vs X 0.7±0.7, p <0.0001), poorer quality of life (QOL-RA X 5.4±1.8 vs X 7.3±1.6, p <0.0001), greater pain (NVS X 56.2±27.5 mm vs X 33.4±25.7 mm, p <0.0001), higher disease activity (DAS28-ESR X 4.3±1.4 vs X 3.3±1.3, p <0.0001), higher frequency of unemployment (71% vs 29%, p=0.015 ) and comorbidities (67% vs 33%, p=0.017) and lower frequency of physical activity (22% vs 35%, p=0.032). In the multivariate analysis, patients with moderate and severe depression had worse functional capacity (OR: 2.1, 95% CI: 1.6-4.3, p <0.0001) and quality of life (OR: 0.7, 95% CI: 0.5-0.8, p <0.0001), independently of disease activity. Conclusion: The prevalence of mayor depression in this Argentinean cohort of patients with RA was 33.8%. The presence of depression had a negative impact on functional capacity and quality of life regardless of disease activity.

Artritis Reumatoide , DepresiónRESUMEN
Recientemente, validamos el cuestionario Quality of Life-Rheumatoid Arthritis Scale (QOL-RA) y detectamos la presencia de algunas limitaciones. Por esta razón, con la autorización de la autora, cambiamos dos preguntas y desarrollamos una nueva versión en español: el QOL-RA II. Objetivo: Validar el QOL-RA II en una cohorte argentina de pacientes con Artritis Reumatoidea (AR). Material y métodos: Estudio de corte transversal. Se incluyeron pacientes ≥18 años de edad, con diagnóstico de AR según criterios ACR-EULAR 2010. Se consignaron datos sociodemográficos, comorbilidades, características clínicas y actividad de la enfermedad. Se administraron los cuestionarios EQ-5D-3L, QOL-RA II, HAQ-A y PHQ-9. A 20 pacientes se les re-administró el cuestionario a los 7 días de haber completado el primero para evaluar reproducibilidad. Análisis estadístico: Test T de Student, ANOVA, Chi². Correlación de Spearman. Alpha de Cronbach. Coeficiente de correlación intraclase. Regresión Logística Multinomial con modelo factorial completo. Regresión lineal múltiple. Resultados: Se incluyeron 430 pacientes, con un tiempo mediano (m) de evolución de 9 años (RIC: 4-16). La m del QOL-RA II fue 6,7 (RIC: 5,3-8). El tiempo promedio para completarlo fue de 1,7±0,57 minutos y para su cálculo de 12±1,7 segundos. Solo 9 (2,1%) pacientes no contestaron alguna pregunta. El cuestionario presentó excelente confiabilidad (α de Cronbach 0,97), reproducibilidad (CCI: 0,96) y buena correlación entre los diferentes ítems y el cuestionario total, sin evidencia de redundancia. QOL-RA II presentó además, buena correlación con EQ-5D-3L (Rho: 0,6), HAQ-A (Rho: 0,55) y PHQ-9 (Rho: 0,56) y moderada con los índices de actividad de la enfermedad DAS28-ERS (Rho: 0,38) y CDAI (Rho: 0,46). Se evidenció peor calidad de vida en aquellos pacientes que no realizaban actividad física (X 6,4±1,9 vs. 7±1,8, p <0,0001), en los desocupados (X 6,1±1,9 vs. 7±1,8, p <0,0001) y en los tabaquistas (X 6,2±1,7 vs. 6,7±1,9, p=0,03). Se observó una tendencia significativa a empeorar la calidad de vida a mayor actividad de la enfermedad. Ajustando por edad, sexo y tiempo de evolución de la enfermedad, las variables que se asociaron significativamente a peor calidad de vida fueron la desocupación, la mayor actividad de la enfermedad, la discapacidad funcional y la presencia de depresión. Conclusión: El QOL-RA II demostró buena validez de constructo, reproducibilidad. Fue fácil de completar y calcular. No se observó redundancia entre las preguntas ni influencia por la edad ni el tiempo de evolución de la enfermedad.
We have recently validated the Quality of Life-Rheumatoid Arthritis Scale (QOL-RA). We have found some limitations, that is why, with the author's permission, we have changed two questions and developed a new Spanish version, QOL-RA II. Objective: To validate the QOL-RA II in an Argentinean cohort of patients with Rheumatoid Arthritis (RA). Material and methods: Cross-sectional study. Patients ≥18 years old, with a diagnosis of RA according to ACR-EULAR 2010 criteria were included. Sociodemographic data, comorbidities, RA characteristics, disease activity current treatment were registered. Questionnaires were administered: EQ-5D-3L, QOL-RA, HAQ-A and PHQ-9. The QOL-RA II was re-administered in 20 patients to evaluate reproducibility. Statistical analysis: Student's T, ANOVA and Chi² tests. Spearman correlation. Cronbach's alpha. Reproducibility using ICC. Multinomial logistic regression with completed factorial model. Multiple linear regression. Results: 430 patients were included, with a median (m) disease duration of 8.9 years (IQR: 4-16). QOL-RA was m 6.6 (IQR: 5.3-8). Mean time to complete it was 1.7±0.57 minutes and to calculate it 12±17 seconds. Only 2.1% of the questionnaires presented missing answers. It showed very good reliability (Cronbach's alpha 0.97), reproducibility (ICC: 0.96) and good correlation between the different items and the total questionnaire, without evidence of redundancy. Besides, QOL-RA II presented good correlation with EQ-5D-3L (Rho: 0.6), HAQ-A (Rho: 0.55) and PHQ-9 (Rho: 0.56) and moderate with DAS28-ESR (Rho: 0.38) and CDAI (Rho: 0.46). Worse quality of life was observed in patients not doing physical activity (X 6.4±1.9 vs. 7±1.8, p <0.0001), unemployed (X 6.1±1.9 vs. 7±1.8, p <0.0001) and current smokers (X 6.2±1.7 vs. 6.7±1.9, p=0.03). Patients with higher disease activity had a significant poorer quality of life. Adjusting by age, sex and disease duration, unemployment, higher disease activity, disability and the presence of depression were independently associated to worse quality of life. Conclusions: QOL-RA II demonstrated good construct validity, reproducibility and reliability. It was easy to complete and calculate. There were no redundancy between questions and it was not influenced by age and disease duration.

El autocuestionario QOL-RA es una herramienta diseñada para valorar la calidad de vida de los pacientes con Artritis Reumatoidea (AR). No requiere licencia para su uso. Objetivo: Validar el cuestionario QOL-RA en una cohorte de pacientes con AR en Argentina. Material y métodos: Estudio de corte transversal. Se incluyeron pacientes ≥18 años de edad con diagnóstico de AR según criterios ACR-EuLAR 2010. Se consignaron datos sociodemográficos, comorbilidades, características de la enfermedad. Se completaron los cuestionarios QOL-RA, EQ 5D-3L, HAQ-A, PHQ-9. Se midió el tiempo para completar y calcular el QOL-RA. Análisis estadístico: Estadística descriptiva. Test T de Student, ANOvA, Chi2. Correlación de Spearman. Alpha de Cronbach. Coeficiente de correlación intraclase. Regresión Logística multinomial con modelo factorial completo. Regresión Lineal múltiple. Resultados: Se incluyeron 258 pacientes, 85,7% eran mujeres, con una edad mediana de 54 años (RIC 45-62). La mediana del QOL-RA fue 6,75 (RIC 5,4-8,1), presentando buena correlación con EQ 5D-3L (Rho: 0,63), HAQ-A (Rho: -0,56), PHQ9 (Rho: -0,54), SDAI (Rho: -0,45) y DAS28-ERS (Rho: -0,44). Peor calidad de vida se asoció con la presencia de comorbilidades (x6,4 ± 2 vs 7 ± 1,7, p=0,01) y no realizar actividad física (x6,7 ± 1,9 vs 7,1 ± 1,7, p=0,004). El tiempo para completar el cuestionario fue de x1,7 ± 0,42 minutos y para calcularlo de x12± 2,1 segundos. La confiabilidad y la reproducibilidad fueron buenas. Sin embargo, 4,3% de los cuestionarios presentaban alguna pregunta faltante y se observó redundancia entre las preguntas 3 y 6. En el análisis de regresión lineal múltiple usando QOL-RA como variable dependiente y ajustando para edad y tiempo de evolución, las variables que se asociaron independientemente a peor calidad de vida fueron: la discapacidad funcional, la actividad de la enfermedad y la presencia de depresión y comorbilidades. Conclusión: El cuestionario QOL-RA demostró buena validez de constructo, reproducibilidad y confiabilidad. Es fácil de completar y calcular. Sin embargo, dada la redundancia entre dos preguntas proyectamos cambiar una de ellas y re-testearlo

UNLABELLED: The objective of the study was to evaluate work disability and its main associated factors in patients with early arthritis. Argentine Consortium for Early Arthritis (CONAART) is the first early arthritis cohort in Argentina. Patients with one or more swollen joints and less than 2 years of symptoms duration were followed up prospectively in 13 departments of rheumatology. Social, demographic, familiar, clinical, and laboratory data were recollected. At first year and every year, X-rays of hands and feet were performed and working status and pharmaco-economic data were recollected. Work status (employed, unemployed, retired) and type of work were assessed by direct interview using a predesigned questionnaire. Eight hundred forty-eight patients were included, rheumatoid arthritis (RA) = 483 (57 %)and undifferentiated arthritis (UA) = 365 (43 %), 694 (81.8 %) were women, median age was 46 years (interquartile range (IQR) 35-55.7) and median symptoms duration 7 months (IQR 3-12). Patients with RA had significantly higher disease activity, worse functional capacity and quality of life, and more severe radiological damage compared to UA patients. However work disability (unemployed patient) was comparable between groups (RA = 21 % versus UA = 18.6 % p = NS). In both groups, unemployed patients had higher disease activity score of 28 joints (DAS28), worse Health Assessment Questionnaire (HAQ) values, and less years of formal education (p value <0.005 in all comparisons). Radiological damage was greater in unemployed patients but this difference did not reach statistical significance. In multivariate analysis, disease activity was the main variable associated with unemployment in both groups. Joint involvement was the main cause of work disability in this cohort of patients with early arthritis, independently of the final diagnosis. KEY MESSAGES: 1. Work disability is higher in patients with inflammatory arthritis as compared to the general population. 2. Prevalence of work disability is comparable among patients with undifferentiated and rheumatoid arthritis. 3. Disease activity is the main disease variable associated with work disability.

Our objective was to analyze the effects of cigarette smoking on disease activity, functional capacity, radiographic damage, serology and presence of extraarticular manifestations in patients with rheumatoid arthritis and undifferentiated arthritis. This is a cross-sectional study of 1,305 patients (729 with rheumatoid arthritis and 576 with undifferentiated arthritis) from CONAART, the Argentine Consortium for Early Arthritis that includes patients older than 16 years with <2 years of disease. Sociodemographic data, clinical characteristics of the disease and smoking history were collected. In patients with rheumatoid arthritis the disease activity score of 28 joints was 5.4 ± 1.3 in current smokers, 5.2 ± 1.4 in former smokers and 5.1 ± 1.4 in never smokers (p = 0.011). The simple erosion narrowing score was higher in current smokers and former smokers than in never smokers (M 14.0, R Q 6.0-21.0; M 15.0, R Q 7.0-24.0; M 10.0, R Q 5.0-17.0; p = 0.006). Current smokers had higher rheumatoid factor titer (M 160.0, R Q 80.0-341.0) than former smokers (M 146.8, R Q 6.03-255.5) and never smokers (M 15.0, R Q 9.0-80.0) (p = 0.004). The variable independently associated with tobacco exposure was simple erosion narrowing score (OR = 1.03, 95 % CI 1.00-1.05; p = 0.012). In patients with undifferentiated arthritis, an association between smoking status and parameters of activity or radiographic damage was not observed. Neither was tobacco exposure related to the presence of extraarticular manifestations or to the degree of disability in any of the two groups of patients. No relation was found between disease activity and severity, and number of packs smoked per year. Tobacco.
