Dr Smith described how Factor IX concentrate was thought to carry the risk of venous thrombosis at the site of infusion (possibly fatal) when administered at a high dosage. Similarly, reports of thrombosis occurred at higher frequency in the early 1980s supposedly due to activated Factor IX. Clinicians had to choose between unheated Factor IX and run the risk of transmitting NANBH or AIDS, or buying heated Factor IX concentrate where it wasn't tested for thrombogenicity.

Dr Snape's understanding was that during the first nine months of 1985 most treatment centres continued to use the BPL unheated product, although heat-treated commercial Factor 9 products were available.

BPL were cautious to release the heated Factor IX product due to potential risk of thromboembolic sequelae being activated. This was allayed following studies in November 1984 which explains the delay in its clinical trials occurring in July 1985 and eventual widespread distribution to October 1985.

Spreadsheet shows annual consumption of Commercial Factor Concentrates mainly for Oxford but also includes data from across the country for individual years (ranging from 1976 to 1983). It reveals that untreated Factor IX continued to be used after 1985 despite it being readily available from the same year.

Dr Craske reported that most reference centres now used commercial heat-treated Factor IX. Dr Mortimer suggested Directors be recommended to only use heat-treated products now due to increased availability.

Dr Aronson, in a paper on Factor IX concentrates, referenced the high number of cases reported of icteric hepatitis in Factor IX concentrates. A survey of sera from haemophilia B patients revealed that the overwhelming majority of patients treated with Factor IX concentrates had markers indicating prior infection with HBV.

Dr Allen wrote to Dr Maycock highlighting that Cutter's product Konyne had an extraordinarily high rate of icteric hepatitis developing from it. This ranged between 50 and 90 percent. Half of these cases proved fatal and Cutter's source of blood was 100 percent from Skid-Row derelicts.

Dr Maycock replied to Dr Bidwell to state there is no objection to the final pool being increased to 500 litres. It was to be prepared from 2 or 3 subpools each of which would pass safety tests, including RIA test for HBsAg.
