One hundred and sixty-six patients with different forms of rheumatic diseases were tissue typed for 26 antigens of the A and B locus of the HLA system, using a modified KN cytotoxicity test. Among 25 patients with confirmed ankylosing spondylitis, 23 had HLA B27 (92 per cent), compared to 2.5 per cent in the normal controls. This confirms the strong association of HLA B27 with ankylosing spondylitis. Eight patients had doubtful AS, five of whom were positive for B27. In 21 patients with mechanical disorders of the spine no B27 was found. Thirty-six patients with osteoarthrosis of the knee joints did not show any significant relationship with any HLA antigens. Twenty-one patients with systemic lupus erythematosus showed an increase of HLA B13 and B17.

We carried out a prospective study of the clinical, laboratory and radiological features of 180 patients with psoriatic arthritis. We initially classified our patients into five groups as described in the publications of Moll and Wright. Thirty-seven per cent had oligoarthritis, 36% polyarthritis, 23% spondarthritis (sacroiliitis and/or spondylitis) and 4% had the mutilans form. The distal joint arthritis type did not exist as an entity and the distal interphalangeal (DIP) joints were affected in all groups. The spondarthritis form includes patients with exclusively axial manifestations and also those who in addition have peripheral arthritis (oligoarthritis, polyarthritis, DIP arthritis). Only 53% of our patients had nail involvement. We found an increase of IgA levels in patients with axial disease. This suggests a relationship between ankylosing spondylitis and psoriatic spondylitis. The HLA-B17/Cw6 association increased in the oligoarticular form. The increase of antigen B17 correlated with the spondarthritic and oligoarthritis forms whereas Cw6 was more important in the oligoarthritis form. An increase of the HLA-B27/Cw1 association and the spondarthritic form was also found. Moreover, we detected a greater incidence of the HLA-B27 antigen in patients with bilateral sacroiliitis (85%) than in patients with unilateral sacroiliitis (22%). Our work revealed that PA is not a harmless disease; 57% of our patients had erosive arthritis while 19% had ARA class III or IV functional impairment.

Seronegative arthritis is part of a multifactorial syndrome which also includes acute anterior uveitis (AAU), psoriasis, inflammatory bowel disease and forms of A-V block and aortic incompetence. The whole syndrome may be referred to as HEreditary Multifocal Relapsing Inflammation (HEMRI). Any sign may occur alone or in combinations with others. The signs may be triggered by infections, the arthritic components are then referred to as reactive arthritis. Genetic factors predetermine who is to contract disease when triggered. HLA-B27 itself is probably of major significance in ankylosing spondylitis and AAU. A genetic factor in linkage disequilibrium with HLA B13 and B17 is instrumental in familial psoriasis. Other genetic factors may determine psoriatic arthritis, and possibly also inflammatory bowel disease and juvenile arthritis. The genetic factors interact with each other and with the environmental factors when producing disease. Diagnosis should be based on demonstrated signs of disease. Classification according to genetic factors reflects etiology, disease manifestations and prognosis.

Two cases of inflammatory joint disease during attacks of aseptic palmo-plantar pustulosis are reported. Both patients had vertebral involvement: disco-vertebral erosions at several levels in one case and spondylitis and intersomatic ossification in the other. One patient also had sacroiliitis and involvement of the anterior thoracic skeleton (costoclavicular joints, costal cartilages ans xiphoid) confirmed by bone scintigraphy. The relation between this cutaneous-articular syndrome and other inflammatory joint diseases, especially ankylosing spondylitis and psoriatic arthropathy are discussed. The very unusual involvement of the anterior thoracic skeleton, the coexistence of aseptic palmo-plantar pustulosis and absence of antigens HLA B27, B13 and B17 suggest a similarity to the pustular osteoarthritis recently described by Japanese workers who grouped this condition with other spondylarthropathies.

Approximately 5% of patients with psoriasis develop chronic inflammatory joint disease which is clearly differentiated from rheumatoid arthritis by several features; absence of prevalence in females, elective involvement of distal joints of hands and feet, negative serologic tests, usually less severe outcome and absence of systemic manifestations. Conversely, psoriatic rheumatism resembles ankylosing spondylitis inasmuch as mainly sacroiliac but also vertebral involvement is common, with, in some instances, development of a typical pelvispondylitis. Thus, psoriatic rheumatism belongs to the group of seronegative spondylarthropathies. The genetic background of psoriatic rheumatism, with the exception of predominantly axial forms which are related to HLA B27, is very similar to that of isolated psoriasis, typified in particular by the frequency of HAL B17, B13 and B38. The immunologic disorders described in psoriasis and, more recently, in psoriatic rheumatism suggest that an immunologic dysfunction probably plays a significant part in the genesis of both conditions; however, the reasons why only a small proportion of patients with psoriasis develop joint disease remain obscure.

One hundred and twenty-two consecutively hospitalized patients with ankylosing spondylitis (AS) were reexamined. Ninety-two per cent were HLA B27 positive. Of the HLA B27 negative patients, 60% were found to have psoriasis, as opposed to 11% of the HLA B27 positive patients. Acute anterior uveitis (AAU) was found only in HLA B27 positive patients, and more frequently in males than in females. The genetic and clinical heterogeneity of AS, together with the overlapping clinical criteria for AS and psoriatic spondylitis, may make the term "Bechterew's syndrome" preferable. Based on these findings and previous reports, we conclude that (i) AAU is a manifestation of Bechterew's syndrome in HLA B27 positive patients, (ii) HLA B27 negative patients without any obvious accompanying manifestations may suffer from psoriatic spondylitis, and (iii) genetic predisposition to psoriasis in persons who are HLA B13, B17 and B37 negative, may interact with the genetic predisposition to Bechterew's syndrome in HLA B27 positive persons and produce Bechterew's syndrome with psoriasis or psoriasis-like skin eruptions.

One hundred and twenty-two consecutive patients hospitalized for ankylosing spondylitis (AS) were reexamined. The frequency of clinical signs and results of tests for associations are presented. Psoriasis was associated with a distal pattern of peripheral arthropathy. Spinal rigidity was predominantly seen in males. Males with phalangeal arthropathy exhibited preserved spinal mobility. This was the case also when HLA B27 positives and patients who did not have psoriasis were considered separately. HLA B27 positive patients in this group had frequently experienced acute anterior uveitis. It seems possible that the disease in such males is the result of combined predisposition to ankylosing spondylitis and psoriatic arthropathy. Hip arthropathy was frequently present in males with spinal rigidity. The associations observed confirm that AS is a heterogenous group of diseases. The term "syndrome" may be suitable for such a heterogenous group, and we prefer the term "Bechterew's syndrome" as the name of this group. When these new findings are added to the previous observations that acute anterior uveitis probably is a clinical, sex-influenced characteristic of HLA B27 positive Bechterew's syndrome, that HLA B27 negative patients with Bechterew's syndrome frequently had psoriasis and were HLA B13 and B17 negative, and that psoriasis was frequent in HLA B27 positive patients as well, we tentatively conclude that different and interacting genetic mechanisms may be involved in the etiology of Bechterew's syndrome.

The aim of the study was to compare the spondyloarthropathy of ankylosing spondylitis (AS) to that of psoriatic arthritis (PsA). Forty patients with AS and 66 patients with PsA underwent a complete assessment according to a standard protocol, including radiographic evaluation and HLA typing. A logistic regression analysis was performed controlling for age, arthritis duration, and sex. A higher frequency of inflammatory neck and back pain and stiffness (p < 0.0002), limitation of back movements (p < 0.0006), grade 4 sacroiliitis (p = 0.007), and syndesmophytes (p = 0.005) was noted in AS, while peripheral arthritis was more common and more severe in patients with PsA (p = 0.002). A lower frequency of HLA B17 (p = 0.02), and a higher frequency of HLA B27 (p = 0.0001), and Cw2 (p < 0.01) was found in AS compared to PsA. Thus, there are clinical, radiologic, and genetic differences in disease expression of the SA of AS and PsA, supporting their classification as distinct entities.
