Impacto económico de los inhibidores en hemofilia tipo A pediátrica / Economic impact of inhibitors in pediatric hemophilia type A

Resumen Introducción: Pocos estudios han evaluado el impacto económico de los inhibidores en hemofilia tipo A en México, especialmente en población pediátrica. Objetivo: Determinar el impacto económico que conlleva el desarrollo de inhibidores en pacientes pediátricos con hemofilia tipo A. Método: Se evaluaron de forma retrospectiva los pacientes con hemofilia tipo A atendidos en un servicio de hematología pediátrica entre diciembre de 2015 y noviembre de 2017, y se determinaron los costos directos e indirectos a partir de la presencia o ausencia de inhibidores. Resultados: El análisis de costos de la población estudiada (n = 24) mostró que el diagnóstico, seguimiento, profilaxis, tratamiento y hospitalización de estos pacientes tuvo un costo de $6 883 187.4 anuales por paciente, de los cuales más de 95 % dependió del uso de factores hemostáticos. El costo anual por paciente en el grupo con inhibidores tuvo un costo de $5 548 765.0, en comparación con $1 334 422.4 del grupo sin inhibidores, 4.2 veces superior. Conclusiones: Se trata del primer estudio nacional que muestra que el desarrollo de inhibidores en pacientes pediátricos con hemofilia tipo A eleva más de cuatro veces la erogación económica derivada de esta enfermedad.

Abstract Introduction: Few studies have assessed the economic impact of inhibitors in hemophilia A in Mexico, especially in the pediatric population. Objective: To determine the economic impact entailed by the development of inhibitors in pediatric patients with hemophilia A. Method: Patients with hemophilia A under the care of a pediatric hematology department between December 2015 and November 2017 were retrospectively assessed. Direct and indirect costs were determined based on the presence or absence of inhibitors. Results: The cost analysis of the study population (n = 24) showed that diagnosis, follow-up, prophylaxis, treatment and hospitalization of these patients had an annual cost of $ 6 883 187.4 per patient, out of which more than 95 % depended on the use of hemostatic factors. Annual cost per patient in the group with inhibitors was $ 5 548 765.0 in comparison with $ 1 334 422.4 in the group without inhibitors, 4.2 times higher. Conclusions: This is the first national study to show that the presence of inhibitors in pediatric patients with hemophilia A increases the cost of the disease more than four times.

Low cost locally prepared fibrin glue for clinical applications: reported of 145 cases. Committee of Bangkok International Hemophilia Training Center.

Fibrin glue (FG) is one of the blood products known to be very useful for local hemostatic measure and as a medically valuable tool for adhesion, sealing, anastomosis, repair microvascular and nerve grafts in medical and surgical procedures. Before 1996, FG was used to a limited extent in Thailand due to the high cost. Technology for locally prepared FG was transferred to Bangkok International Hemophilia Training Center of the World Federation of Hemophilia (IHTC-WFH) in July 1996 by Prof. Uri Martinowitz and the late Prof. Henri Horoszowski. Since then FG has been widely used and proved to be very useful in Thailand. This paper reports 145 cases using low cost locally prepared FG at Ramathibodi Hospital during November 1996 to December 1997. A total of 145 cases with age range from 5 months to 73 years, which included 55 pediatrics and 90 adults, 100 males and 45 females. The amount of FG used was 1-80 ml per case. Clinical procedures included dental surgery (46), open heart surgery (35), ENT (28), orthopedic (13) including 2-3 joint correction in one session in 2 hemophiliacs, neurology (11), plastic repair (7), liver (2) and severe bleeding in dengue hemorrhagic fever (3). Forty-seven cases had hemostatic disorders. The result of local hemostatic, adhesive and sealant effect of FG was satisfactory with no complications. In open heart surgery, the amount of content in chest drain decreased and none required reopen-surgery to stop bleeding. Dental surgery was performed in 43 patients with bleeding disorders i.e. hemophilia, idiopathic thrombocytopenic purpura, leukemia, severe thrombocytopenia, patients on anticoagulant, etc. Only 3 cases (7%) required blood component compared to all of the 50 no-FG controlled cases (100%) that required blood component therapy. FG has proved to be very useful in many aspects i.e. minimizing blood product usage, decreasing medical workload, reducing medical cost and increasing patients' convenience and satisfaction in particular.
