    Hemos estudiado un total de 38 pacientes afectos con S铆ndrome de Sj枚gren, de ellos 13 corresponden a formas primarias (sin otra conectivopat铆a asociada) y 25 secundarios a Artritis Reumatoide. Hemos eliminado del estudio los pacientes con enfermedad pulmonar previa conocida, h谩bito tab谩quico y otras conectivopat铆as a fin de unificar la patolog铆a. Se encontraron un total de 17 pacientes con algunas alteraci贸n en las pruebas funcionales respiratorias (44,7%), que clasificaron de la siguiente forma: 10 pacientes con patrones obstructivos (6 de ellos exclusivamente con obstrucci贸n de v铆a a茅rea peque帽a 鈥搈enor de 2 mm-), 6 pacientes con restricci贸n respiratoria y un paciente con insuficiencia respiratoria mixta de predominio restrictivo. Entre los afectados desde el punto de vista respiratorio predominan aquellos con A.R. asociada, con un claro predominio de las mujeres en todos los grupos. Se compararon todos los grupos afectados entre si y con el grupo sin afectaci贸n pulmonar, no encontr谩ndose ning煤n dato cl铆nico, anal铆tico, radiol贸gico o inmunol贸gico distintivo de ninguno de ellos, salvo que el grupo restrictivo mostr贸 una PO2 significativamente menor que el resto. Importa destacar la baja expresividad radiol贸gica de todos los casos, lo que nos hace proponer el estudio funcional respiratorio como rutinario en estos pacientes. Hemos encontrado una alta incidencia de signos y s铆ntomas del aparato locomotor entre nuestros pacientes con S.S.P., hecho tal vez condicionado por haber sido diagnosticados todos ellos en la Secci贸n de Reumatolog铆a. CONCLUSIONES. 1. Hemos encontrado alteraci贸n de las pruebas funcionales respiratorias en 17 pacientes de los 38 estudiados (44,7%) con S.S. y sin afectaci贸n pulmonar previa conocida. 2. En los pacientes con S.S. asociado a Artritis Reumatoide se dio alteraci贸n de las pruebas funcionales respiratorias en el 56% de los casos, cifra superior a la que se encuentra en la literatura para pacientes con A.R. sin S.S. asociado. 3. Los pacientes que mostraron alguna alteraci贸n en las pruebas de funci贸n respiratoria se agruparon de la siguiente forma: 10 pacientes con obstrucci贸n al flujo a茅reo (4 con obstrucci贸n puro y 6 con obstrucci贸n de v铆as a茅reas menores de 2 mm. exclusivamente); 6 pacientes con restricci贸n respiratoria pura y 1 con insuficiencia respiratoria mixta de predominio restrictivo. 4. Los pacientes con S铆ndrome de Sj枚gren asociado a Artritis Reumatoide presentan con m谩s frecuencia enfermedad pulmonar (56%) que los que tienen un S铆ndrome de Sj枚gren aislado (23%). 5. Se ha encontrado un claro predominio femenino en los pacientes con S铆ndrome de Sj枚gren, tanto en los que tienen afectaci贸n respiratoria como en los que no la tienen. 6. La comparaci贸n entre pacientes con alteraciones funcionales respiratorias y sin alteraciones, no arroja significaci贸n estad铆stica en cuanto a la edad, tiempo de evoluci贸n de la A.R. o tiempo de evoluci贸n del S.S. As铆 mismo tampoco existen diferencias en cuanto al estad铆o radiol贸gico o funcional de la A.R. o grado de afectaci贸n en la biopsia labial. 7. Los par谩metros anal铆ticos (VSG elevada, hiperproteinemia, anemia, ANA positivos), en general, est谩 m谩s alterados en el grupo con afectaci贸n pulmonar, aunque no alcanza significaci贸n estad铆stica. 8. No encontramos correlaci贸n entre la cl铆nica respiratoria, radiolog铆a pulmonar y pruebas funcionales respiratorias, siendo de destacar la escasa expresividad de la radiolog铆a pulmonar en todos nuestros casos. 9. Los pacientes con alteraci贸n funcional respiratoria de tipo Obstructivo fueron los m谩s numerosos entre los afectados (10 de 17), no existiendo ning煤n dato cl铆nico, anal铆tico, radiol贸gico o inmunol贸gico distintivo del grupo. 10. Los pacientes con Restricci贸n pulmonar, as铆 mismo, no presentaron ning煤n dato cl铆nico, anal铆tico, radiol贸gico o inmunol贸gico peculiar, salvo el de predominar tambi茅n entre los pacientes con A.R. y tener una PO2 significativamente menor que el resto de los grupos. 11. Estimamos oportuno el estudio de la funci贸n respiratoria en los pacientes con S铆ndrome de Sj枚gren a煤n en los casos con estudios radiol贸gicos pulmonares negativos, dada la baja expresividad radiol贸gica de la patolog铆a intersticial en fases iniciales. 12. En cuanto a la afectaci贸n del aparato Locomotor entre nuestros pacientes con S铆ndrome de Sj枚gren, se encontraba presente en el 50% de los casos, algunos de ellos con diagn贸stico de Poliartritis sin filiar, lo que nos hace proponer la b煤squeda sistem谩tica de s铆ntomas de sequedad entre los pacientes con s铆ndromes articulares mal definidos

    Switching TNF antagonists in patients with chronic arthritis: An observational study of 488 patients over a four-year period

    The objective of this work is to analyze the survival of infliximab, etanercept and adalimumab in patients who have switched among tumor necrosis factor (TNF) antagonists for the treatment of chronic arthritis. BIOBADASER is a national registry of patients with different forms of chronic arthritis who are treated with biologics. Using this registry, we have analyzed patient switching of TNF antagonists. The cumulative discontinuation rate was calculated using the actuarial method. The log-rank test was used to compare survival curves, and Cox regression models were used to assess independent factors associated with discontinuing medication. Between February 2000 and September 2004, 4,706 patients were registered in BIOBADASER, of whom 68% had rheumatoid arthritis, 11% ankylosing spondylitis, 10% psoriatic arthritis, and 11% other forms of chronic arthritis. One- and two-year drug survival rates of the TNF antagonist were 0.83 and 0.75, respectively. There were 488 patients treated with more than one TNF antagonist. In this situation, survival of the second TNF antagonist decreased to 0.68 and 0.60 at 1 and 2 years, respectively. Survival was better in patients replacing the first TNF antagonist because of adverse events (hazard ratio (HR) for discontinuation 0.55 (95% confidence interval (CI), 0.34-0.84)), and worse in patients older than 60 years (HR 1.10 (95% CI 0.97-2.49)) or who were treated with infliximab (HR 3.22 (95% CI 2.13-4.87)). In summary, in patients who require continuous therapy and have failed to respond to a TNF antagonist, replacement with a different TNF antagonist may be of use under certain situations. This issue will deserve continuous reassessment with the arrival of new medications. 漏 2006 Gomez-Reino and Loreto Carmona; licensee BioMed Central Ltd

    Environmental and societal factors associated with COVID-19-related death in people with rheumatic disease: an observational study

    Published by Elsevier Ltd.Background: Differences in the distribution of individual-level clinical risk factors across regions do not fully explain the observed global disparities in COVID-19 outcomes. We aimed to investigate the associations between environmental and societal factors and country-level variations in mortality attributed to COVID-19 among people with rheumatic disease globally. Methods: In this observational study, we derived individual-level data on adults (aged 18-99 years) with rheumatic disease and a confirmed status of their highest COVID-19 severity level from the COVID-19 Global Rheumatology Alliance (GRA) registry, collected between March 12, 2020, and Aug 27, 2021. Environmental and societal factors were obtained from publicly available sources. The primary endpoint was mortality attributed to COVID-19. We used a multivariable logistic regression to evaluate independent associations between environmental and societal factors and death, after controlling for individual-level risk factors. We used a series of nested mixed-effects models to establish whether environmental and societal factors sufficiently explained country-level variations in death. Findings: 14 044 patients from 23 countries were included in the analyses. 10 178 (72路5%) individuals were female and 3866 (27路5%) were male, with a mean age of 54路4 years (SD 15路6). Air pollution (odds ratio 1路10 per 10 渭g/m3 [95% CI 1路01-1路17]; p=0路0105), proportion of the population aged 65 years or older (1路19 per 1% increase [1路10-1路30]; p<0路0001), and population mobility (1路03 per 1% increase in number of visits to grocery and pharmacy stores [1路02-1路05]; p<0路0001 and 1路02 per 1% increase in number of visits to workplaces [1路00-1路03]; p=0路032) were independently associated with higher odds of mortality. Number of hospital beds (0路94 per 1-unit increase per 1000 people [0路88-1路00]; p=0路046), human development index (0路65 per 0路1-unit increase [0路44-0路96]; p=0路032), government response stringency (0路83 per 10-unit increase in containment index [0路74-0路93]; p=0路0018), as well as follow-up time (0路78 per month [0路69-0路88]; p<0路0001) were independently associated with lower odds of mortality. These factors sufficiently explained country-level variations in death attributable to COVID-19 (intraclass correlation coefficient 1路2% [0路1-9路5]; p=0路14). Interpretation: Our findings highlight the importance of environmental and societal factors as potential explanations of the observed regional disparities in COVID-19 outcomes among people with rheumatic disease and lay foundation for a new research agenda to address these disparities.MAG is supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (grant numbers K01 AR070585 and K24 AR074534 [JY]).
