Acute transplant rejection induced by blood transfusion reaction to the Kidd blood group system.

Many renal transplant centres now try to avoid blood transfusion prior to renal transplantation, to avoid alloimmunization due to antibody production against donor antigens usually present on contaminating white cells. Post- or peri-operative transfusions are usually not considered to present problems, since the patient is heavily immunosuppressed. We present a patient who suffered a rare transfusion reaction, that we believe may have initiated a severe vascular rejection of a kidney transplant, probably mediated by Kidd blood group antigens.

Leucodepletion for transmissible spongiform encephalopathies.

Transmissible spongiform encephalopathies (TSEs) have been recognised around the world for many years. Creutzfeldt-Jakob disease (CJD), one of the human forms of TSE, has been studied widely and thus far has not proved a great threat to human health. The emergence of two new TSEs--bovine spongiform encephalopathy (BSE) in cattle and variant Creutzfeldt-Jakob disease (vCJD) in humans in the UK--has caused great concern.

Reducing red blood cell transfusion in elective surgical patients: the role of audit and practice guidelines.

In 1996, we prospectively audited peri-operative transfusion practice in elective surgical patients over a 3-month period. Two-unit transfusions represented 60% of all transfusions. Haemoglobin was measured infrequently prior to transfusion and the main 'trigger' for transfusion was an estimated blood loss in excess of 500 ml.

Hepatitis C lookback programme: a single hospital experience.

As part of the national Hepatitis C (HCV) Lookback Programme, HCV-infected donors donating blood after September 1991 were identified and the fate of their previous donations received at a single hospital were traced; 123 of 160 implicated blood components were traceable and transfused. Only 19 recipients were alive and traceable and were tested for HCV. Nine of the 14 recipients (64%) of HCV-positive donations and 2 of 5 recipients (40%) of HCV-indeterminate donations had evidence of HCV infection.

Impact of aprotinin on blood transfusion requirements in liver transplantation.

A retrospective study was carried out to ascertain the blood bank provision required to support a liver transplant programme and to assess the effect of intraoperative aprotinin on blood product requirements in liver transplant recipients with cirrhosis. Sixty patients with end-stage liver disease underwent 62 consecutive orthotopic liver transplants between October 1988 and January 1991. The total and intraoperative requirements of red cells, platelets and fresh frozen plasma (FFP) were analysed for three groups of liver transplant recipients, those without cirrhosis (n = 15), those with cirrhosis (n = 25) and those with cirrhosis who received intraoperative aprotinin (n = 20).
