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)

Catastrophic health expenses and impoverishment of households of patients with rheumatoid arthritis.

BACKGROUND: The cost of certain diseases may lead to catastrophic expenses and impoverishment of households without full financial support by the state and other organizations. OBJECTIVE: To determine the socioeconomic impact of the rheumatoid arthritis (RA) cost in the context of catastrophic expenses and impoverishment. PATIENTS AND METHODS: This is a cohort-nested cross-sectional multicenter study on the cost of RA in Mexican households with partial, full, or private health care coverage. Catastrophic expenses referred to health expenses totaling >30% of the total household income. Impoverishment defined those households that could not afford the Mexican basic food basket (BFB). RESULTS: We included 262 patients with a mean monthly household income (US dollars) of $376 (0­18,890.63). In all, 50.8%, 35.5%, and 13.7% of the patients had partial, full, or private health care coverage, respectively. RA annual cost was $ 5534.8 per patient (65% direct cost, 35% indirect). RA cost caused catastrophic expenses in 46.9% of households, which in the logistic regression analysis were significantly associated with the type of health care coverage (OR 2.7, 95%CI 1.6­4.7) and disease duration (OR 1.024, 95%CI 1.002­1.046). Impoverishment occurred in 66.8% of households and was associated with catastrophic expenses (OR 3.6, 95%CI 1.04­14.1), high health assessment questionnaire scores (OR 4.84 95%CI 1.01­23.3), and low socioeconomic level (OR 4.66, 95%CI 1.37­15.87). CONCLUSION: The cost of RA in Mexican households, particularly those lacking full health coverage leads to catastrophic expenses and impoverishment. These findings could be the same in countries with fragmented health care systems.
