Prothrombin complex concentrates.

Abstract

The use of the prothrombin complex products for the treatment of inhibitor patients is discussed in relation to our difficulty in identifying the effective therapeutic principle, as well as the factors responsible for thrombogenicity. It would appear that combination of factors is responsible for either or both therapeutic and thrombogenic phenomena. Possible intermediate or aggregate forms of the procoagulants are present in the products, protected from the neutralizing effects of antithrombin III.

Two new nonsense mutations in type Ia antithrombin III deficiency at Leu 140 and Arg 197.

Using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and DNA sequencing, the molecular basis of hereditary type Ia antithrombin III (AT III) deficiency was disclosed in two families. One mutation was a change from T to A in the codon of TTA for Leu 140 forming a stop codon of TAA, which was confirmed by mutated primer-mediated PCR-HindIII digestion. The application of this method demonstrated that all four affected members had the mutant allele in a heterozygous state and that none of unaffected subjects had this mutation. Another mutation in the second family was a change from C to T in the codon of CGA for Arg 197 also forming a stop codon of TGA, which was confirmed by PCR-HaeIII digestion. Based on these, it was concluded that the two new nonsense mutations in the AT III gene in a heterozygous state are the molecular basis of hereditary type Ia AT III deficiency.
