HLA antigens and bronchogenic carcinoma in the Greek population.

The distribution of HLA antigens was studied in 85 Greek patients with bronchogenic carcinoma. Fifty-seven specific HLA antisera were used to determine 27 HLA-A and B antigens, with the two-stage standard NIH microlymphocytotoxicity assay. The results were compared with those in a control group, consisting of 400 healthy individuals. In the whole group of patients there was a significantly higher frequency of HLA-AW19 and HLA-A29 (p less than 0.003 and p less than 0.006 respectively) and a lower frequency of HLA-A2 and HLA-A3 (p less than 0.014 and p less than 0.006 respectively) than in the control population. In patients with squamous cell carcinoma there was a significantly higher frequency of HLA-AW19 and lower frequency of HLA-A2 (p less than 0.02 and p less than 0.05 respectively). In small cell carcinoma patients there was a significantly lower frequency of HLA-A3 (p less than 0.04) than among the controls. In patients with adenocarcinoma no significant change of HLA antigen frequencies was observed when compared to the controls.

Adenocarcinoma

HLA-B27 frequency in Greek patients with acute anterior uveitis.

The histocompatibility antigen HLA-B27 was identified in 12 out of 33 patients with acute non-granulomatous anterior uveitis. This is a frequency of 36.36%, compared with 4.72% in controls. Seven patients had in addition evidence of systemic disease, including ankylosing spondylitis, sacroiliitis, Reiter's disease, Still's disease, and rheumatoid arthritis. Five of these were HLA-B27 positive, which suggests that the uveitis in many of these cases has a similar aetiology to the uveitis in those with rheumatic disease. It appears that the more severe cases of acute anterior uveitis are related more frequently to the presence of HLA-B27.

Acute Disease

Thymoma associated with pure red cell aplasia, immunoglobulin deficiency and an inhibitor of antigen-induced lymphocyte transformation.

A case of thymoma associated with pure red cell aplasia and hypogammaglobulinaemia is described in which the anaemia was of abrupt onset, following removal of the tumour. Tests of immunological function showed abnormalities of both humoral and cellular immunity. The patient was found to have a serum inhibitor of antigen-induced lymphocyte transformation which disappeared after immunosuppressive therapy at the same time that erythroblasts reappeared in the marrow. It is suggested that the triad of thymoma, pure red cell aplasia and immunoglobulin deficiency are manifestations of 'pluripotent' stem cell failure; in this case the inhibitor of lymphocyte transformation may have been related to the factor which also inhibited red cell maturation.
