Bone marrow transplantation was performed on a 15 year old girl with
chronic myelogenous leukemia
. The bone marrow was obtained from her younger sister, who was human leukocyte antigen haplo-identical but major ABO incompatible. As a result, the condition of pure red cell aplasia (PRCA) persisted over a long period of time. In order to overcome major
ABO incompatibility
, erythrocytes were eliminated from the bone marrow graft before transplantation, and methotrexate and cyclosporine (CsA) were used to prevent graft-versus-host disease (GVHD). Administration of erythropoietin proved ineffective. B19 parvovirus infection could not be detected during that time. Agglutinin titers decreased to less than fourfold in parallel with the recovery of erythrocytes. Reports on similar PRCA have been limited to cases of transplantation with
ABO incompatibility
and cases where CsA was administered to prevent GVHD. This suggests that
ABO incompatibility
and CsA might be related to the development of PRCA.

Between February 1971 and October 1980, 34 patients with leukemia or aplastic anemia received bone marrow transplants from HLA-identical siblings whose lymphocytes did not react in a mixed leukocyte culture. The donors of 10 patients were ABO-incompatible, and for five pairs the
ABO incompatibility
was major. Plasma exchanges followed by a red blood cell exchange transfusion reduced the anti-A titres to 1:4 or less in these patients. The
ABO incompatibility
had no adverse effect on the results of marrow transplantation. Twenty-two patients, including 16 of the 20 who received their transplant after Jan. 1, 1980, are still living. Seven of the 15 patients with acute leukemia have survived 89 to 466 days, and 4 of the 6 with
chronic myelogenous leukemia
(
CML
) have survived 117 to 545 days. Of the 13 patients with aplastic anemia, 11 are alive up to 8 years after transplantation. Marrow transplantation, when possible, is the treatment of choice for young patients with acute leukemia in remission and for patients with aplastic anemia. Marrow transplantation may also prove to be effective in patients with
CML
.

We observed massive hemolysis after allogeneic peripheral blood stem cell transplantation with minor
ABO incompatibility
(the donor was group O and the recipient group A). The patient was a 21-year-old man diagnosed as having Philadelphia chromosome-positive
chronic myelogenous leukemia
. On day 7 post-transplant, there was abrupt onset of massive hemolysis necessitating supportive treatment with transfusions. During the allogeneic peripheral blood stem cell transplantation the patient had received 2 x 10(8) CD3 positive cells/kg and 7.8 x 10(7) CD19 positive cells/kg donor lymphocytes with stem cells. The present case shows that in allogeneic peripheral blood stem cell transplantation with
ABO incompatibility
, severe hemolysis occurs early after transplantation presumably due to the transfusion of a large number of lymphocytes.

We evaluated the feasibility of allogeneic transplantation of CliniMACS-selected peripheral CD34+ cells from siblings (four patients: AML-M4, M2, CLL, MDS); nonoptimal related donors (two patients: AML-M4,
CML
); and unrelated donors (two patients:
CML
, ALL, both without engraftment after preceding URDBMT). All patients had high-risk of aGVHD and/or graft failure due to multiple transplantation risk factors. Conditioning treatment was myeloablative (n=7) or nonmyeloablative (n=1). Immunosuppression consisted of CsA (n=8), Mtx (n=5), ATG (n=4). Selected CD34+ cells were transplanted (average 3.91 x 10(6)/kg, range 1.29 to 7.27 x 10(6)/kg) together with 0.01 to 0.5 x 10(7) CD3+ cells/kg to assure proper engraftment. The remaining CD34-negative fraction was cryopreserved for further CD3+ cell add-back. Average recovery and purity of CD34+ cells following CliniMACS selection were 74% and 97%. No severe complications were observed in the first 100 days. Regeneration times were satisfactory in seven of eight patients (87.5%) with ANO > 0.5 g/L and Plt > 50 g/L reached on average on days +26 and +32 (range 15 to 29 and 15 to 67), respectively. In three patients (37.5%) T-lymphocytes were added-back one to three times (due to low numbers of initially transfused CD3+ cells in two patients, in one patient with PRCA caused by
ABO incompatibility
). One to four additional transplantations of nonselected peripheral cells were performed on days +28 to +270 in consequence of infections (CMV-two patients; parvovirus-one patient), poor regeneration and residual disease (one patient) and prolonged transfusion dependency (one patient). Severe aGVHD grade III or IV developed in three patients (37.5%) following the nonselected cells transplantation. Finally, five patients (62.5%) are alive and in remission (median follow-up 815 days). We conclude that allogeneic transplantation of selected peripheral CD34+ cells (CliniMACS) with controlled add-back of CD3+ cells is an effective, well, tolerated procedure in high-risk patients.

ABO incompatibility
is not a contraindication for allogeneic bone marrow transplantation, but this procedure requires an extra effort for erythrocyte or plasma depletion in certain well established conditions. Some acute or delayed immunohematological complications such as acute or chronic hemolysis and pure red cell aplasia may be encountered. In this study the outcome and transplant related complications of ABO incompatible and identical cases, who have received allogeneic peripheral blood stem cells from their HLA identical siblings were compared with each other. Ninety-one patients (
CML
36, AML 37, other 18) were analyzed retrospectively including 51 (60.4%) ABO identical patients and 36 (39.6%) ABO mismatched (MM) patients, who have a bi-directional MM (n= 5), major MM (n= 16), minor MM (n= 9) and Rh MM (n= 6). Median follow up was 13 (0.5-43.0) months. We did not observed any significant differences between two groups (identical vs non-identical) in terms of acute hemolysis preceding stem cell infusion, peritransplant transfusion demand, acute- and chronic graft versus host disease. There was no change in estimated disease free survival and overall survival durations. We did not observed any influence of ABO/Rh incompatibility on short term outcome in allogeneic peripheral blood stem cell transplantation in our series and did not recommend further manipulation of the infused stem cells.
