[Articular chondrocalcinosis. Association with B15 antigen].

Antigens of HLA loci A, B and DR were determined in 35 elderly patients with primary articular chondrocalcinosis and compared with a control population. The B15 antigen was present in 13 out of 35 patients, i.e.

[Articular chondrocalcinosis in elderly patients and parathyroid hormone levels].

Serum parathyroid hormone was assayed in 16 elderly patients with primary, roentgenographically proved, articular chondrocalcinosis. Mean value, i.e.

[HLA and rheumatoid arthritis].

In a study on the frequency of the HLA A, B, C and DR antigens seen in 100 controls and 31 patients with rheumatoid arthritis, the authors found a significant increase in the DR4 antigen in rheumatoid arthritis. (50% as against 25%; X2 = 8,5; 0,04 greater than Pc greater than 0,008; RR = 3,43). The other antigens on loci A, B.

[Medical treatment of osteoarticular tuberculosis].

The authors report 45 personal cases observed over the last ten years, from a series of 520 cases collected during a multi-centre enquiry of the French Society of Rheumatology and a review of the literature; they discuss the present tendencies in the treatment of bone and joint tuberculosis. Antibiotic and chemotherapy uses drugs which are more and more effective, easier and easier to manipulate, ensuring in almost all cases a lasting cure with frequent conservation of joint function, shortening the natural course of the disease, and preventing or curing its complications. The role of surgery thus becomes more restricted, the period of rest may be shortened and it may becomes less strict in many cases; on the other hand, physiotherapy is becoming more important in this treatment.
