POST-TRANSFUSION GRAFT-VERSUS-HOSTDISEASE AFTER OPEN HEART SURGERY
StR,—Graft-versus-host disease (GVHD) can develop aftertransfusions in patients with deficient cell-mediated immunityl thatis congenital (eg, severe combined immunodeficiency disease) oracquired (eg, leukaemia or advanced carcinoma). However, weknow of no report in the English language or post-transfusionGVHD after open heart surgery.
In Japan, there have been several reports of "postoperativeerythroderma (POE)", a condition characterised by fever, rashes,agranulocytosis, and aplastic marrow, with rapid deteriorationresulting in death; most cases have followed open heart surgery 2 Atfirst, drug allergy was suspected.3 In a typical case of POE thepatient, about 10 days after a seemingly uneventful recovery fromopen heart surgery, has a fever and rash; transaminase levels rise;diarrhoea often develops; and then there is rapidly progressivepancytopenia, aplastic marrow, and erythroderma, and the patientdies from- septicaemia. These findings resemble post-transfusionGVHD, except that there seems to be no cause for the immuno-deficiency.4 Ino et al2 suggested that POE be called "GVHD likesyndrome". The incidence is 1 in every 300-400 cases of open heartsurgery in Japan.The pancytopenia in POE progresses so rapidly that it is very
difficult to get enough lymphocytes for HLA typing. However, wehave succeeded in two cases, both men with only one child. Onepatient was 68 years old and the other 44. Both receivedunirradiated fresh blood from random donors. No parents wereavailable for testing but HLA typing of the patients and their wivesand children revealed that the patients’ HLA phenotypes were notthose deduced from the child’s HLA findings (see figure). Thewives confirmed repeatedly that there was no chance that thehusband was not the father of the child. We strongly suspect that thepatient’s lymphocytes had been replaced by those of the donors.This is consistent with post-transfusion GVHD.

Although more open heart surgery is done in the United Statesthere have been no reports of POE in that country. We suspect thatfresh blood--especially when used immediately after collection,which is the common practice in Japan-increases the risk of thisdisease.

PAROXYSMAL NOCTURNAL HAEMOGLOBINURIAAND PREGNANCY
SIR,-Paroxysmal nocturnal haemoglobinuria (PNH) is a
chronic haemolytic disorder the manifestations of which include apredisposition to thromboembolism and Budd-Chiari syndrome ;2the latter may be precipitated by stress, including pregnancy.3-5Experience of pregnancy in PNH is limited but awareness of therisks involved has prompted the suggestion that conception shouldbe avoided if possible. 6We report experience with a patient who hashad two healthy babies at full term, showing that, at least in the morebenign forms of PNH, uncomplicated pregnancy is possible despitesevere thrombocytopenia.The patient was first seen in 1978 at the age of 22 with
palpitations, easy fatigue, and shortness of breath. Laboratoryfindings were: haemoglobin 4-6 g/dl, total white cell count
2-5 x 109/1 (41 % neutrophils, 1 % eosinophils, 51 % lymphocytes,7% monocytes), and platelet count 127 x 109/1. The diagnosis wasestablished by strongly positive Ham’s acid lysis and sucrose watertest. Bone-marrow aspiration and trephine biopsy showed wellmarked erythroid hyperplasia with megaloblastic haematopojesisand absent iron stores.
Coagulation screens and platelet function studies were normal.Haemoglobin was maintained at 10 g/dl with washed packed redcells and supplementary iron and folate. Treatment did not
aggravate the haemolysis.She remained well for 5 years until, in April, 1979, she was
admitted to hospital with an acute haemolytic episode associatedwith pelvic sepsis. ,
In 1981 the patient presented 2 months pregnant. There was noprogression to bone-marrow hypoplasia or evidence for leukaemictransformation. She was vaginally delivered of a full-term normalchild. Her platelet count fluctuated between 30 and 50 x 109/1.
In October, 1984, she again presented 2 months pregnant andwas delivered of a full-term normal child; on this occasion allogeneicplatelet cover was needed to control bleeding from the thrombo-cytopenia. Evaluation post partum showed that she had progressedto severe bone-marrow hypoplasia.
Despite the apparently benign nature of this patient’s clinical andhaematological syndrome, her illness is now following the well-recognised course in which normal bone marrow becomes increas-ingly hypoplastic and ultimately aplastic. Reversion to fetal typehaematopoiesis with rising HbF levels and expression of i antigenprovides further evidence for the expression of this acquired defectin haematopoiesis, and bone-marrow transplantation may yet berequired. Nevertheless, despite the usual view that pregnancy is toohazardous in patients with PNH, a poor outlook may not beinevitable.
