Terapia biológica, sobrevida y seguridad en padecimientos reumáticos. Resultados del Registro Nacional Biobadamex 1.0 / Patient survival and safety with biologic therapy. Results of the Mexican National Registry Biobadamex 1.0

Mediante registro multicéntrico ambispectivo de 2.047 pacientes con diversas afecciones reumáticas bajo terapia biológica (TxB), incluyendo un grupo control de pacientes con artritis reumatoide (AR) sin TxB, se reporta la supervivencia en la terapia y eventos adversos asociados a su uso. Los diagnósticos más frecuentes son: AR 79,09%; espondilitis anquilosante (EA) 7,96%; artritis psoriásica (APso) 4,40%; lupus eritematoso sistémico (LES) 3,37% y artritis idiopática juvenil (AIJ) 1,17 por ciento. Un análisis de 1.514 casos de la muestra total reportó que la tasa de incidencia para cualquier evento adverso es de 178/1.000 pacientes-año en TxB vs. 109/1.000 pacientes-año en controles con un riesgo relativo (RR) de 1,6 (IC del 95%, 1,4-1,9); para eventos adversos graves un RR de 15,4 (IC del 95%, 3,7-63,0 p < 0,0001). La supervivencia global de TxB es del 80% a 12 meses, el 61% a 24 meses, el 52% a 36 meses y el 45% a 48 meses. La tasa de mortalidad estandarizada (TME) es de 0,23 (IC del 95%, 0,0-49,0) para TxB vs. 0,00 (IC del 95%, 0,0-0,2) para controles. Se concluye que la TxB se asocia a un mayor riesgo de presentar eventos adversos, especialmente infecciosos, en comparación con pacientes sin TxB. La mortalidad de los pacientes expuestos a TxB no es mayor que la esperada para la población general ajustada a edad y sexo (AU)

This work reports patient treatment survival and adverse events related to Biologic Therapy (BT), identified by a multicenter ambispective registry of 2047 rheumatic patients undergoing BT and including a control group of Rheumatoid Arthritis (RA) patients not using BT. The most common diagnoses were: RA 79.09%, Ankylosing Spondilytis 7.96%, Psoriatic Arthritis 4.40%, Systemic Lupus Erythematosus 3.37%, Juvenile Idiopathic Arthritis 1.17%. A secondary analysis included 1514 cases from the total sample and was performed calculating an incidence rate of any adverse events of 178 × 1000/ BT patients per year vs. 1009 x 1000/control group patients per year with a 1.6 RR (IC95% 1.4-1.9). For serious adverse events the RR was: 15.4 (95% CI 3.7-63.0, P<.0001). Global BT survival was 80% at 12 months, 61% at 24 months, 52% at 36 months and 45% at 48 months. SMR: 0.23 (95%CI 0.0-49.0) for BT vs. 0.00 (95%CI 0.0-0.2) for the control group. In conclusion, BT was associated to a higher infection risk and adverse events, compared to other patients. Mortality using BT was not higher than expected for general population with same gender and age (AU)

[Relapsing polychondritis: clinical and therapeutic analysis of 15 Mexican cases]. / Policondritis recidivante: análisis de 15 casos.

BACKGROUND: relapsing polychondritis (RP) is a rare multisystem disease of unknown etiology, characterized by recurrent episodes of inflammation and cartilage destruction. The aim was to present fifteen cases, analyzed in a clinical and therapeutic perspective. METHODS: fifteen cases from three different cities of Mexico, diagnosed with Damiani criteria, were included. Clinical features, treatment given and outcome were recorded. RESULTS: nine men and six women with mean age of 52.4 years met the criteria for RP; the average change was 86.7 months. The dominant clinical manifestations were: 83 % auricular chondritis, 66 % dysphonia, 60 % arthritis and 53 % with eye involvement. Treatment included: 93 % received corticosteroids, 60 % received methotrexate, 46 % received no steroidal anti-inflammatory treatment, 46 % received immunosuppressant therapy, and two cases received biologic therapy. The clinical course showed 34 relapses in 12 cases. Complications included hoarseness in seven cases, tracheal stenosis in six case, and hearing loss in three cases. There were five deaths, three from respiratory complications, one from renal failure and another from a cerebral vascular event. CONCLUSIONS: the fifteen cases with RP presented were characterized by multisystem clinical courses and serious respiratory complications. The diagnostic and therapeutic situations merited highly medical specialized approaches.
