Determinación de los multímeros del factor von willebrand en población mexicana

Background: Von Willebrand disease is an inherited disease in which the structure, function, and concentration of von Willebrand factor are altered, as well as the platelet von Willebrand factor endothelium interaction. In Mexico there are no epidemiological records of the disease. Only a few isolated studies have been reported from the clinical and hematological standpoint.

Methods: We studied 155 Mexican Mestizos: 75 with presumptive diagnosis of von Willebrand disease, 15 with suspected diagnosis of hemophilia A and 65 healthy donors (controls). Basic coagulation tests, special tests and classification test (analysis of multimeric composition) were carried out.

Results: There were 15 patients with clinical diagnosis of hemophilia A, 75 patients with suspected von Willebrand disease of which 50 were diagnosed as the following types and subtypes: Type 1 (62%), Type 2 (22%) [subtypes: 2A (14%), 2B (2%), and 2N (6%)] and Type 3 (16%).

Conclusion: It has been reported that analysis of von Willebrand factor is a method that meets the characteristics for the diagnosis of von Willebrand disease. It is necessary to implement this methodology to study and improve the specific diagnoses..
