Real-world Effectiveness and Safety of JAK Inhibitors in Rheumatoid Arthritis: A Single-centre Study / Efectividad y seguridad en el mundo real de los inhibidores de JAK en la artritis reumatoide: Estudio unicéntrico

Background/objective: To assess the effectiveness and safety of Baricitinib and Tofacitinib in rheumatoid arthritis (RA) patients in “real world” conditions. Methods: A single centre retrospective study was performed including RA patients who had initiated treatment with Baricitinib or Tofacitinib from September-2017 to January-2020. Demographic, clinical, laboratory, efficacy and safety variables were collected from baseline and at months 1, 3, 6, 12, 18 and 24. Effectiveness was evaluated by changes from the baseline in DAS28, SDAI, HAQ and acute phase reactants. Safety analysis included adverse events due to any cause, including infection or intolerance. Infection was considered severe if it implied hospitalization. Statistical analysis consisted in Bayesian mixed ordinal regression models including the monotonic effect of each visit and Kaplan–Meier survival curves. Results: Overall, 98 patients were included. A significant reduction of disease activity scores was noted in both groups. No difference between either treatment was detected in terms of effectiveness even in first line, after bDMARD failure, in monotherapy nor combined therapy. A total of 54 adverse events were recorded of which 18 were considered relevant. The incidence of infection, including Herpes Zoster, was similar in both groups. No patients in either group suffered any tuberculosis, thromboembolic event, malignancy, death or cardiovascular adverse events. Survival analysis did not show any difference between groups. Conclusion: Baricitinib and Tofacitinib are both comparable in terms of effectiveness and safety in real world conditions.(AU)

Antecedentes/objetivo: Evaluar la efectividad y seguridad de baricitinib y tofacitinib en los pacientes con artritis reumatoide (AR) en condiciones del «mundo real». Métodos: Se realizó un estudio retrospectivo unicéntrico que incluyó a los pacientes de AR que habían iniciado tratamiento con baricitinib o tofacitinib de septiembre de 2017 a enero de 2020. Se recopilaron las variables demográficas, clínicas, de laboratorio, de eficacia y seguridad a nivel basal, y transcurridos uno, 3, 6, 12, 18 y 24 meses. La efectividad se evaluó mediante los cambios desde el punto basal en cuanto a DAS28, SDAI, HAQ y los reactantes de fase aguda. El análisis de seguridad incluyó los episodios adversos debido a cualquier causa, incluyendo infección o intolerancia. Se consideró infección grave cuando se produjo hospitalización. El análisis estadístico consistió en modelos mixtos de regresión ordinaria de Bayes incluyendo el efecto monotónico de cada visita y las curvas de supervivencia de Kaplan-Meier. Resultados: En total se incluyeron 98 pacientes. Se observó una reducción significativa de la actividad de la enfermedad en ambos grupos. No se detectó diferencia alguna entre ninguno de los tratamientos en términos de efectividad incluso en primera línea, tras el fallo de bDMARD, en monoterapia ni en terapia combinada. Se registró un total de 54 episodios adversos, de los cuales se consideraron relevantes 18. La incidencia de la infección, incluyendo herpes zoster, fue similar en ambos grupos. Ningún paciente de cualquiera de los grupos padeció episodios adversos tales como tuberculosis, episodio tromboembólico, malignidad, muerte ni episodios adversos de tipo cardiovascular. El análisis de supervivencia no reflejó diferencia alguna entre los grupos. Conclusión: Baricitinib y tofacitinib son comparables en términos de efectividad y seguridad en condiciones del mundo real.(AU)

18 F-FDG PET/TC en pacientes con polimialgia reumática: despistando vasculitis / 18 F-fluorodeoxyglucose positron emission tomography/computed tomography in patients with polymyalgia rheumatica: Screening for vasculitis

OBJETIVO: La polimialgia reumática (PMR) puede asociarse a vasculitis de grandes vasos (VGV). Este trabajo pretende evaluar el papel de 18F-FDG PET/TC en el diagnóstico de VGV asociado a PMR. MATERIALES Y MÉTODO: Estudio retrospectivo de pacientes con PMR. Se recogieron datos clínicos, analíticos, reactantes de fase aguda (RFA) (PCR, VSG), y a quienes tenían clínica persistente, elevación de RFA, precisaban dosis elevadas de corticoterapia o cuadros atípicos de PMR (febrícula, pérdida de peso, etc.) se realizó 18F-FDG PET/TC. RESULTADOS: Veintitrés pacientes se incluyeron; el 48% (11) de los cuales tuvieron VGV asociada a PMR. La localización fue heterogénea pero en su mayoría involucró a la aorta. En cuanto al tratamiento, se añadieron fármacos modificadores de la enfermedad a más del 80% de los pacientes con VGV. Los pacientes con VGV tenían niveles de PCR elevados comparado con aquellos con PMR aislada. CONCLUSIONES: La VGV en PMR no es infrecuente, tanto la clínica como los valores de PCR elevados deben hacer sospechar la posibilidad de VGV asociada. El estudio de imagen 18F-FDG PET/TC es una herramienta útil identificando VGV asociada a PMR

OBJECTIVE: Polymyalgia rheumatica (PR) can be associated with large vessel vasculitis (LVV). We evaluate the diagnostic role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) and its impact on the treatment of LVV associated with PR. MATERIALS AND METHODS: Retrospective study of patients diagnosed with PR. Data was collected from health records. Blood analysis included acute-phase reactants (APR), C-reactive protein (CRP) and erythrocyte sedimentation rate. An 18F-FDG PET/CT scan was performed in those patients whose symptoms persisted, in those with elevated APR, those who required higher doses of steroids or those who had atypical features of PR (low-grade fever, weight loss, among others). RESULTS: Twenty-three were eligible; 48% (n = 11) of the patients were diagnosed with LVV associated with PR. The site was heterogeneous, but mostly involved the aorta. In 80% of the patients with LVV, a disease-modifying antirheumatic drug was added to their treatment. Elevated CRP values were associated with the likelihood of presenting LVV. CONCLUSIONS: LVV is not uncommon, clinical features and elevated CRP levels should raise suspicion of LVV associated with PR. 18F-FDG PET/CT is useful in identifying LVV associated with PR
