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.

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.

Acute bone marrow aplasia associated with intravenous administration of deferoxamine (desferrioxamine).

The authors report the clinical course and fatal outcome of a case of acute bone marrow aplasia, after intravenous administration of deferoxamine (desferrioxamine) to a 16-year-old girl with homozygous beta-thalassaemia. The type of aplasia was mainly that of a megakaryocytic thrombocytopenia, but the 2 other haemopoetic series were also involved. The absence of any other toxic factors and the quite rapid onset of the bone marrow failure after this type of treatment strongly suggest that intravenous administration of high doses of deferoxamine was the potential toxic factor.

HLA antigens and Adamantiades-Behçet's disease (A-BD) in Greeks.

The distribution frequency of HLA-A and B antigens was determined in 24 Greek individuals with Adamantiades-Behçet's disease (A-BD) as well as in 280 controls. The standard NIH technique was used for tissue typing. There was an increased incidence of HLA-B5 in the patients group (75% compared to controls 32%). The calculated P corrected value was Pc less than 0.02, the relative risk (RR) was 6.23 and the aetiological fraction (EF) 0.68. This study agrees with the reported association between A-BD and HLA-B5 in other populations from the Mediterranean basin, the Middle East and Far East.

HLA antigens in diabetics with calcified shoulder periarthritis (CSP).

The distribution frequencies of HLA-A and B antigens was determined in 94 maturity onset diabetics (40 with CSP and 54 without CSP), as well as in 400 unrelated age- and sex-matched Greek controls. The standard NIH technique was used for tissue typing. There was an increased prevalence of the antigen B27 only in diabetics with CSP (35%) when compared either to the controls (6.8%) or to diabetics without CSP (9.2%). The calculated p-corrected values were Pc = 0.00027 and Pc greater than 0.005 respectively. These findings indicate that the MHC in man may control the genetic susceptibility of a subgroup of insulin-independent diabetics to develop CSP.
