Osteoporosis in psoriatic arthritis: Risk factors, insufficiency fractures and its association with the disease activity.

OBJECTIVE: The prevalence of osteoporosis (OP) and insufficiency fractures in psoriatic arthritis (PsA) remains controversial. The aim of this study was to describe the prevalence of OP and insufficiency fractures in a representative cohort of patients with PsA, and to analyse its association with general risk factors and characteristics of the psoriatic disease in our geographical area. METHODS: Multi-centric, descriptive study of patients with PsA. We recorded clinical characteristics, as well as protective and risk factors for OP and insufficiency fractures. Hip and lumbar densitometry and lateral X-ray of the spine were evaluated. Descriptive statistics for OP and risk factors were calculated. The patients with OP were compared to those without by univariate analyses, and results were adjusted by age and sex. The association of OP and fractures with clinical characteristics was analysed by logistic regression. RESULTS: 166 patients (50 men; 116 women) were included. OP was present in 26.5%, and it was more frequent in women and patients above 50 years old. Insufficiency fractures occurred in 5.4% of the total sample. In the logistic regression, OP was associated with age over 50 [OR 3.7; 95% CI (1.2-11.6); p=.02]. No association with clinical parameters was found. The most frequent risk factors among patients with OP were vitamin D insufficiency, sedentary behaviour, low calcium intake, and active smoking. In the logistic regression, OP was associated with early menopause [OR 11.7; 95% CI (1.29-106.0); p=.029] and sedentary behaviour [OR 2.3; 95% CI (1.0-5.2); p=.049]. CONCLUSIONS: In patients with PsA, OP is more frequent in women and patients over 50 years old. A sedentary lifestyle and early menopause may add extra risk for OP. Type, duration disease, and treatments are not associated with OP or insufficiency fractures.

Objetivo: El objetivo de este estudio fue describir la prevalencia de osteoporosis (OP) y fracturas por insuficiencia en una cohorte representativa de pacientes con artritis psoriásica (APs) y analizar su asociación con factores de riesgo generales y características de la enfermedad psoriásica en nuestra área geográfica. Métodos: Estudio multicéntrico y descriptivo de pacientes con APs. Se registraron las características clínicas, así como los factores protectores y de riesgo de OP y fracturas por insuficiencia. Se evaluó la densitometría de cadera y lumbar y la radiografía lateral de columna. Se calcularon las estadísticas descriptivas de la OP y los factores de riesgo. Los pacientes con OP se compararon con los que no la tenían mediante análisis univariantes, y los resultados se ajustaron por edad y sexo. La asociación de la OP y las fracturas con las características clínicas se analizó mediante regresión logística. Resultados: Se incluyeron 166 pacientes (50 hombres; 116 mujeres). La OP estaba presente en el 26,5% y era más frecuente en mujeres y pacientes mayores de 50 años. Se produjeron fracturas por insuficiencia en el 5,4% de la muestra total. En la regresión logística la OP se asoció con la edad superior a 50 años (OR: 3,7; IC 95%: 1,2-11,6; p=0,02), con la menopausia precoz (OR: 11,7; IC 95%: 1,29-106,0; p=0,029) y el comportamiento sedentario (OR: 2,3; IC 95%: 1,0-5,2; p=0,049). Conclusiones: En pacientes con APs la OP es más frecuente en mujeres y en aquellos mayores de 50 años. Un estilo de vida sedentario y una menopausia precoz pueden añadir un riesgo adicional de OP. El tipo, la duración de la enfermedad y los tratamientos no se asocian a las fracturas OP ni a las fracturas por insuficiencia.(AU)

Use of benzodiazepines and antidepressants in patients who attend a Rheumatology clinic / Prevalencia de consumo de benzodiacepinas y antidepresivos en los pacientes que acuden por primera vez a la consulta de reumatología

ABSTRACT Introduction: During the last decades, benzodiazepines (BZD) and antidepressants (ADP) have been among the most prescribed therapies in all developed countries. They have side effects, and BZD carry a risk of abuse and dependence disorders. The purpose of this study was to evaluate the prevalence of BZD and ADP among patients who attend a Rheumatology clinic, as well as the indication for these drugs. Methods: The study included patients who were referred for the first time to the Rheumatology clinic. Demographical data, reason for referral, and final diagnosis were recorded. The indication for ADP and/or BZD was recorded, as well as the duration of treatment. Sample size was estimated for a 0.05% alpha risk. Univariate and multivariate analyses were performed in order to study the relationships with the demographical or clinical characteristics. Results: A total of 350 patients were included (women 77.1%, men 22.9%). Most of them (73.4%) had been referred for musculoskeletal pain. More than a third (36.6%) of patients were on BZD and/or ADP. The most frequent reasons for their prescription were anxiety, depression, and insomnia. The final diagnosis in the clinic was a non-inflammatory condition in 82%, and an inflammatory one in 18%. In the univariate analyses, the use of BZD/ADP was associated with female gender (p<.001), unemployment (p<.001) and non-inflammatory final diagnosis (p < .001). In the multivariate analyses, the use of BZD and/or ADP was associated with female sex (p = .002 [OR 3.4, 95% CI; 1.6-7.4]), and a non-inflammatory final diagnosis, specifically fibromyalgia (p = .007 [OR 16.1, 95% CI; 2.2-120.7]). Conclusion: Use of BZD and ADP is high and associated with non-inflammatory disease.

RESUMEN Introducción: Durante las últimas décadas, las benzodiacepinas (BZD) y los antidepresivos (ADP) han estado entre las terapias más prescritas en todos los países desarrollados. Estos fármacos tienen efectos secundarios y las BZD pueden ocasionar abuso y problemas de dependencia. El objetivo de este estudio fue evaluar la prevalencia de consumo de BZD y ADP entre los pacientes que acuden a una consulta de reumatología por primera vez, así como la indicación para ellos. Métodos: Se incluyeron pacientes remitidos por primera vez a la consulta de reumatología. Se registraron los datos demográficos, el motivo de la derivación y el diagnóstico final. Con respecto al tratamiento con ADP y/o BZD, se registraron su duración y la indicación de la prescripción. El tamaño de la muestra se estimó para un riesgo alfa de 0,05%. Se realizaron análisis univariantes y multivariantes para estudiar las asociaciones con características demográficas o clínicas. Resultados: Se incluyeron 350 pacientes (mujeres 77,1%, hombres 22,9%). La mayoría de ellos habían sido remitidos por dolor musculoesquelético (73,4%). Más de un tercio (36,6%) de los pacientes estaban en tratamiento con BZD y/o ADP. Las causas más frecuentes para su prescripción fueron ansiedad, depresión e insomnio. El diagnóstico final fue patología no inflamatoria en el 82% de los casos e inflamatoria en el 18% de estos. En el análisis univariante, el uso de BZD y/o ADP se asoció con el sexo femenino (p< 0,001), el desempleo (p< 0,001) y el diagnóstico de patología no inflamatoria (p< 0,001). En el análisis multivariante, el uso de BZD y/o ADP se asoció con el sexo femenino (p=0,002 [OR 3,4; IC 95% 1,6-7,4]) y el diagnóstico de patología no inflamatoria, específicamente con la fibromyalgia (p = 0,007 [OR 16,1; IC 95% 2,2-120,7]). Conclusión: El consumo de BZD y ADP es frecuente y está asociado con patología no inflamatoria.

RENACER study: Assessment of 12-month efficacy and safety of 168 certolizumab PEGol rheumatoid arthritis-treated patients from a Spanish multicenter national database.

OBJECTIVE: To assess effectiveness and safety of certolizumab PEGol (CZP) in rheumatoid arthritis (RA) patients after 12 months of treatment and to detect predictors of response. METHODS: Observational longitudinal prospective study of RA patients from 35 sites in Spain. Variables (baseline, 3- and 12-month assessment): sociodemographics, previous Disease Modifying Anti-Rheumatic Drug (DMARD) and previous Biological Therapies (BT) use; TJC, SJC, ESR, CRP, DAS28, SDAI. Response variables: TJC, SJC, CRP, ESR, and steroids dose reductions, EULAR Moderate/Good Response, SDAI response and remission, DAS28 remission. Safety variables: discontinuation due to side-effects. Descriptive, comparative and Logistic regression analyses were performed. RESULTS: We included 168 patients: 79.2% women, mean age 54.5 years (±13.2 SD), mean disease duration 7.5 years (±7.3 SD). Mean number of prior DMARD: 1.4 (±1.2 SD), mean number of prior BT was 0.8 (±1.1). Mean time on CZP was 9.8 months (±3.4 SD). A total of 71.4% were receiving CZP at 12-month assessment. Baseline predictors of response: lower prior number DMARD; low number prior BT; higher CRP, ESR, TJC, SJC, DAS28 and SDAI (p < 0.05) scores. A 25/46.4% Moderate/Good Response, a 20% SDAI remission, and a 44% DAS28 remission were observed. We observed 48 discontinuations (28.6%), 31 due to partial or complete ineffectiveness, and 17 due to side-effects. CONCLUSIONS: CZP showed benefit in severe RA patients, with significant reduction of all effectiveness parameters, despite the high prevalence of previous BT exposure in our series. We found CRP, ESR, prior DMARD/BT number, TJC, SJC, DAS28, and SDAI as baseline predictors of response. CZP was mostly well tolerated.
