[Infective morbidity of replacement therapy in congenital coagulation deficiencies and its effects on demand of coagulation factors]. / La morbilidad infecciosa del tratamiento sustitutivo en los déficit congénitos de coagulación y su repercusión en la demanda de los factores de coagulación.

BACKGROUND: Analysis of the infective morbidity and mortality secondary to replacement hemotherapy in the population with congenital coagulation deficiencies (CCD) and their consequences on the demand for coagulation factors. METHODS: The 46 patients with CCD diagnosed in the autonomous community (AC) of the Balearic Islands (32 with hemophilia A, 6 with hemophilia B, 4 with von Willebrand's disease 2 with factor VII, 1 with factor X, and 1 with factor XII deficiencies) were investigated for infective morbidity and use of blood products from 1982 to 1987. RESULTS: 97% of the patients had some hepatitis marker, 77% had antibodies against human immunodeficiency virus (HIV) and 17% fulfilled the criteria for the acquired immunodeficiency syndrome (AIDS). There were 7 deaths (15%). The morbidity and mortality increased with age and use of blood products. There was a 46% reduction in factor VIII use between 1982 and 1986, from a mean yearly consumption per hemophiliac patient of 33444 international units (IU) to 18080 IU. CONCLUSIONS: The study results show a high prevalence of hepatitis and HIV, an important reduction in the demand of manufactured coagulation factors and a 15% reduction in the population with CCD during the study years.
