ABSTRACT

Antecedentes: El presente artículo muestra la evidencia y recomendaciones de la eficacia y seguridad de las terapias hasta hoy aprobadas y disponibles en México para el tratamiento de la osteoporosis en su etapa severa o establecida, con la finalidad de establecer una postura terapéutica acerca de la eficacia y seguridad para esta etapa del padecimiento, de acuerdo con las cédulas descriptivas del Cuadro Básico y Catálogo de Medicamentos del Sector Salud en México. Métodos: Se realizó una revisión sistemática y narrativa de la evidencia de teriparatida y denosumab, desde su perfil farmacológico, efectividad y seguridad derivado de ensayos clínicos, además de un análisis de las recomendaciones generales de las principales guías de práctica clínica nacionales e internacionales. Resultados: La evidencia establece que teriparatida y denosumab pertenecen a clases terapéuticas distintas, con mecanismos de acción biológicamente opuestos e indicaciones de uso claramente diferenciadas en sus respectivas cédulas, por lo cual no son sustituibles ni intercambiables en la terapia de osteoporosis severa. Ambas representan la mejor opción disponible hasta el momento para esta etapa del padecimiento. Son similares en su eficacia de prevención de nuevas fracturas vertebrales por fragilidad, con un RR de 0,35 (IC 95%: 0,22-0,55) para teriparatida, y de 0,32 (IC 95%: 0,26-0,41) para denosumab. La reducción absoluta del riesgo es mayor con teriparatida 9,3% (21 meses) que con denosumab 4,8% (36 meses). Conclusiones: Nuestros resultados concuerdan con las recomendaciones disponibles en las principales guías de práctica clínica nacionales e internacionales, por lo que son propuestas ambas terapias como consecutivas y nunca como sustitutivas.(AU)


Background: This article presents evidence and recommendations regarding the efficacy and safety of the approved and available therapies in Mexico to treat severe or established osteoporosis with the aim of developing a position regarding therapeutics in this stage of the disease, according to the descriptive cards of the National Drug Formulary of the National General Health Council of Mexico. Methods: We performed a systematic and narrative review of the evidence of teriparatide and denosumab, from their pharmacological profile, effectiveness, and safety derived from clinical trials, as well as an analysis of the general recommendations of the national and international clinical practice guidelines. Results: The evidence establishes that teriparatide and denosumab belong to different therapeutic classes, with biologically opposed mechanisms of action and indications of use, which are clearly differentiated in their respective national codes, therefore these drugs cannot be substitutable or interchangeable in severe osteoporosis therapy. Both represent the best options currently available for this stage of the disease; being similar in their efficacy in preventing new vertebral fragility fractures, with an RR of .35 (CI 95%; .22-.55) for teriparatide, and .32 (CI 95%: .26-.41) for denosumab. The absolute risk reduction is higher with teriparatide 9.3% (21 months) compared with denosumab at 4.8% (36 months). Conclusions: Our results agree with the recommendations available in national and international clinical practice guidelines, with both therapies proposed as a sequential, but not a substitute, treatment.(AU)

ABSTRACT

BACKGROUND: Anthracyclines are effective drugs in pediatrics cancer treatment. However, anthracycline-induced cardiotoxicity (AIC) is a serious adverse drug reaction that affects the survival in patients treated for childhood cancer. CLINICAL CASES: Case 1: Nine-year-old girl with stage IV Hodgkin lymphoma with 12 epirubicin doses and a cumulative dose of 576 mg/m2. After last chemotherapy dose, the patient was admitted with systemic inflammatory response, asthenia and adinamia. Echocardiography: LVEF of 22%, SF 11% and moderate mitral regurgitation. Patient died 2 days after diagnosed with dilated cardiomyopathy secondary to anthracyclines. Case 2: Fifteen-year-old girl with stage IV Burkitt lymphoma with two epirubicin doses and a cumulative dose of 90 mg/m2. After the last cycle, the patient developed several infectious foci. Echocardiography: LVEF of 49%, SF 20% and dilated left ventricle with septal flattening. Patient died 13 days after diagnosis of dilated cardiomyopathy by anthracyclines. CONCLUSION: AIC is a problem in pediatric patients receiving anthracyclines, monitoring is essential to detect the onset of cardiac damage to provide an intervention to prevent heart failure progress.


Introducción: las antraciclinas son fármacos eficaces en el tratamiento de pacientes pediátricos con cáncer. Sin embargo, la cardiotoxicidad inducida por antraciclinas (CIA) es una reacción adversa grave que afecta la sobrevida de niños y jóvenes. Casos clínicos: el caso 1 estuvo constituido por una paciente de nueve años con linfoma de Hodgkin estadio IV con 12 ciclos de quimioterapia con epirrubicina y una dosis acumulada de 576 mg/m2. Después del último ciclo de quimioterapia, la paciente ingresó con respuesta inflamatoria sistémica, astenia y adinamia. El ecocardiograma reportó una FEVI de 22 %, FA de 11 % e insuficiencia mitral moderada. La paciente falleció dos días después con diagnóstico de cardiomiopatía dilatada secundaria a antraciclinas. El caso 2 fue el de una paciente de 15 años con linfoma no Hodgkin tipo Burkitt estadio IV, con dos ciclos de quimioterapia con epirrubicina y una dosis acumulada de 90 mg/m2. Después del último ciclo, la paciente presentó diversos focos infecciosos. El ecocardiograma reportó una FEVI de 49 %, una FA de 20 % y dilatación del ventrículo izquierdo con aplanamiento septal. La paciente falleció 13 días después del diagnóstico de cardiomiopatía dilatada por antraciclinas. Conclusión: la CIA es un problema en los pacientes pediátricos que reciben antraciclinas. El monitoreo durante y después de la quimioterapia es indispensable para detectar el inicio del daño cardiaco a fin de brindar una intervención oportuna que evite la evolución a una insuficiencia cardiaca.
