...stand if the treatment has to be repeated often-as it usually does. And all transfusions carry the risk of hepatitis infection or severe allergic reactions. It was not until 1965 that a Stanford University physiologist, Judith Graham Pool, developed a technique of freezing, thawing and centrifuging fresh plasma to concentrate the AHF. (The rest of the plasma could still be broken down into a dozen other life-saving fractions...
...frozen state, this cryoprecipitate kept indefinitely and could be quickly processed for intravenous infusion in a solution averaging ten to 20 times the potency of plasma. But infusion took up to an hour, and the hemophiliac usually had to go into a hospital to get it. The material could be extracted from only the freshest of plasma. Even the short delay between collection by a mobile blood unit and delivery at a blood center was long enough to destroy or damage...
...blood scientist at the University of North Carolina, collaborated with Dr. Edward Shanbrom of the Hyland (Los Angeles) division of Baxter Laboratories to perfect a new AHF six or seven times as strong as Dr. Pool's cryoprecipitate. The new preparation, 30 to 50 times as active as plasma, has just gone on the market...
...done in the doctor's office or an out-patient clinic. One of the first and most grateful beneficiaries of the new treatment system is David M. Raatz, a California attorney who lives in Monrovia and practices in San Marino. At 26, Raatz has had gallons of plasma and concentrates to stanch the bleeding that recurs most commonly in his ankles, knees and elbows. He never used to know when he would be able to appear in court when a case was called; at best, he might have to hobble in on crutches...
...Shanbrom foresees a day when patients will enjoy still greater convenience. Some batches of AHF concentrate have been made 1,000 times more potent than plasma. Eventually, Brinkhous is confident, this will become the standard AHF, so safe and stable that hemophilia victims will be able to carry it around and inject it themselves, into muscle, just as diabetics now do with insulin...
