Risk of Infection with Replacement Products

The use of cryoprecipitate, some factor VIII concentrates, and fresh-frozen plasma carries several important risks. For example, transmission of hepatitis B virus (HBV), HCV, and HIV may occur.45 In the 1980s, more than 90% of multiply transfused patients with hemophilia became HIV positive musik4d, with the subsequent development of acquired immunodeficiency syndrome (AIDS).

Many of these patients have died from the disease. The advent of sterile concentrates together with rigid donor testing begun in 1985, and the availability of recombinant products, has greatly reduced the risk of HIV infection through blood product administration lucky77slot. AIDS cases associated with hemophilia B has been less common, probably because of the rarity of this condition.

A look at hemophilia mortality rate from 1900 to 1990 reveals the terrible impact of HIV infection wayang88. Survival increased from 1970, when factor VIII replacement first became available, to 1980, with a median life expectancy of 68 years.

However, from 1980 to 1990, this decreased to 49 years. Most of this effect was caused by infection with HIV from contaminated blood products.45 During the 1970s and 1980s, more than 90% of patients treated with plasma-derived clotting factor concentrates became infected with mpo999. This exposure rate has been greatly reduced on the basis of donor screening for HCV antibodies since the later 1980s, viral inactivation procedures started in 1985, and the use of ultrapure concentrates.

Lastly comment

As a result of the earlier contaminated blood pool, however, more than 80% of adult patients with hemophilia are infected with HCV. More than 25% of adult patients with hemophilia have biopsy-demonstrated cirrhosis, and HCV infection is the second leading cause of death in this population. Confection with HIV increases the risk for liver failure 1xbitc.
