Present knowledge of the HL-A system as it relates to lymphoproliferative disease is reviewed briefly. Preliminary results from a current study demonstrate an elevated frequency of Aw33 and depressed frequency of B17 associated with non-Hodgkin's lymphoma-leukemia. In somewhat weaker association, Aw24 and Aw33 are elevated in follicular-center-cell lymphomas, while Bw44 is depressed. It is concluded that more specific subclassification of the lymphomas according to immunologic concepts may aid in correlating the disease with HL-A type as it has for Hodgkin's disease.

In this report we analyzed interrelations between cell quantity in lymphocyte subsets and lymphocyte immunogenetic (HLA) markers in 30 untreated patients with Hodgkin's disease (HD). We defined percentage and the absolute number of peripheral blood lymphocyte subsets expressing CD3, CD4, CD8, CD16, CD25 and CD72 markers for HD patients referring to their HLA phenotype (A, B, Cw loci and DRB1). HD patients had decreased absolute number of all the lymphocyte subsets. This was apparently associated with reduced number of peripheral blood lymphocytes, since their subset shares remained similar to those of healthy volunteers. HD patients had different HLA repertoire: some displayed simultaneous exertion of four antigens in A and B loci ("full house" patients) and others - reduced HLA repertoire ("non-full house" patients). Simultaneous analysis of lymphocyte subset rearrangements and HLA expression revealed that "full house" patients had no significant rearrangements in lymphocyte subsets, except reduced CD4(+) and increased CD25(+) lymphocytes. The reduction of expressed HLA alleles interrelated with reliable decrease of CD3(+), CD4(+), CD16(+) cells. Expression of such HLA alleles as A1, A2, B13, B16, B17, B21, B27, DR2 and DR4 also interrelated with significant decrease in some lymphocyte subsets, of which CD4(+) cells prevailed. The most distinct reduction of lymphocyte subsets interrelated with expression of B17 and DR2 HLA loci. Hence, in HD patients pathological rearrangements of lymphocyte subsets are strictly associated with their HLA expression.
