A 43-year-old woman developed life-threatening refractory thrombocytop
enia following autologous peripheral blood stem cell transplantation f
or metastatic breast carcinoma. Anti-PL(A1) antibodies were demonstrat
ed in the patient's plasma. Treatment with intravenous immunoglobulin
and transfusion of PL(A1)-negative blood products restored platelet re
sponsiveness, PL(A1) alloantibodies should be considered as a possible
cause of severe refractory thrombocytopenia in marrow transplant pati
ents. It is important to make this diagnosis as the mainstay of treatm
ent is the avoidance of blood products from PL(A1)-positive donors (98
% of the population).
