Subcorneal pustular dermatosis and monoclonal IgA.

A patient with subcorneal pustular dermatosis was found to have a circulating monoclonal IgA kappa immunoglobulin. Direct immunofluorescence studies revealed IgA kappa deposits in the subcorneal zone of the epidermis. Circulating IgA kappa reacting with the subcorneal zone of normal human epidermis was demonstrated by indirect immunofluoresence. It is speculated that IgA deposition might be implicated in the pathogenesis of subcorneal pustular dermatosis.

[Augmentation of HL-A A9 antigen in malignant melanoma, principally in metastatic or recurrent forms. Apropos of 105 cases of melanoma of which 34 were serious forms].

HLA-A and B phenotypes of 105 patients suffering from malignant melanomas were determined, with special regard for metastatic form or relapse. A highly significant increase of the HLA-A9 antigen is seen (X2 = 17.47); such data had already been shown by van Wijek [2], but other authors did not find this abnormality when studying melanomas whose histologic form was not specified.

[Study of a population carrying HLA B27 antigen compared with a population without B27, in the detection of ankylosing spondylitis].

Comparative study of 2 groups matched for age and sex, 39 subjects with B 27 and 40 subjects without B 27, chosen at random from blood donors, leads to the conclusion that the former complain of chronic low back pain and joint manifestations, and show a reduction in the range of movement of the lumbar spine, significantly more frequently than the latter. While radiological abnormalities of the sacro-iliac joints considered individually do not permit separation of those bearing the antigen from the controle, grouping them together shows that there are more cases of stage III sacro-ilitis among those with B 27. In all, 5 cases of spondylitis defined according to the New York criteria were found in this way in the group with B 27, 12.8 per cent as against 3 per cent in the controls. From these results, the incidence of rheumatic spondylitis can be estimated as between 0.8 and 1.7 per cent.

Rheumatic symptoms in Crohn's disease and the HLA system.

The study of the distribution of the HLA phenotypes among 55 patients suffering from Crohn's disease did not show any significant difference compared to a control population. On the other hand, the same study limited to patients suffering both from Crohn's disease and peripheral articular manifestations showed a significant increase in the frequency of the HLA BW17.

[Rheumatic manifestations in 80 cases of Crohn's disease].

Out of a series of 80 patients suffering from Crohn's disease, 31 presented rheumatic manifestations. In 16 subjects this took the form of synovitis closely dependent on the enteritic evolution, which developed after the alimentary symptoms, and which worsened as they did and sometimes regressed as they did following medical or surgical treatment. In combination with erythema nodosum, aphtosis, and conjunctivitis, synovitis appears to be the expression of an immune response to the enteritic lesion. Three cases of chronic polyarthitis and 6 cases of asymptomatic sacro-ileitis were also observed, and 6 cases of spondylarthritis of a minor radiological type were observed that evolved independently of the Crohn's disease. Typing according to the HLA system using 26 antigens was carried out in 44 subjects; no difference in phenotype frequency was found between a control group (blood donors) and the group of subjects with Crohn's disease alone; however, the antigen W 17 was found significantly more frequently in those subjects with peripheral arthritis and the antigen W 27 was found more frequently in those with spondylarthritis. These findings suggest, although it is not certain, the existence of genetic susceptibility to rheumatic manifestations in certain sites in patients with Crohn's disease.

Selective deficiencies in complement component : a family with hereditary C2 deficiency.

We report herein a new case of C2 deficiency in a patient with systemic lupus. The subject and one of her brothers, who shows no clinical manifestations, are hymozygous C2 deficient. All other family members are heterozygous for the C2 deficiency. Gene for C2 deficiency (C2d) was shown to be inherited with HLA-A9, B7/Bfs and HLA-A10, B27/Bfs haplotypes. This association has not previously been described.
