Spondyloarthropathies are rare in Africa and there is little data regarding HLA association. We prospectively studied 19 patients with spondyloarthropathy, recording clinical details and performing tissue typing (ABC loci). There were 9 patients with ankylosing spondylitis (8 males), all had severe spinal disease but none had ocular or cardiac involvement and HLA-B27 antigen was not found in any of the 7 patients tested; only one patient possessed a B7 crossreacting antigen. The 10 patients with Reiter's syndrome (8 males) had typical clinical features but again the HLA-B27 tissue type was not found. B7-CREG antigen was found in 7 of the 10 patients with Reiter's syndrome.

Patients with juvenile spondyloarthropathy who carry HLA B27 antigen or have a family history of ankylosing spondylitis may have marked tarsometatarsal arthritis. This may be associated with hindfoot involvement and result in a supination deformity. Spontaneous fusion with complete obliteration of the tarsometatarsal joints may occur.

The case is reported of a 42 year old white woman meeting currently used diagnostic criteria for both ankylosing spondylitis and systemic lupus erythematosus (SLE). As found in a previously described similar case of a black man, HLA typing showed antigens associated with both SLE and seronegative spondyloarthropathy. This case thus supports the hypothesis that the two diseases occur together only when this rare combination of HLA antigens is present.

In a Yupik Eskimo population, the prevalence, incidence and clinical features of rheumatoid arthritis (RA) were similar to those described for the United States population in general. More frequent than RA were seronegative spondyloarthropathic disorders, many of which could not be classified by existing disease criteria. Of the adult patients with spondyloarthropathy only half could be classified as having Reiter's syndrome (RS), ankylosing spondylitis (AS) or psoriatic spondylitis. The remaining patients had many signs and symptoms consistent with spondyloarthropathy, but they either did not meet the diagnostic criteria for any specific disease or had features pathognomonic of more than one. The clinical manifestations of the patients who did not meet standard disease definitions are summarized and compared to those of the patients with RS, AS and psoriatic spondylitis. Because of the many shared features, we believe that these as yet unclassified disease states belong with AS and RS in a single spondyloarthropathic disease spectrum and should be defined and recognized as such.

The present study describes the profile of seronegative spondarthritides (SSA) in young servicemen. SSA was diagnosed in 63 patients from a prospective study on spondyloarthropathy. The SSA group consisted of ankylosing spondylitis (AS, 40 patients), Reiter's syndrome (RS, 6) and SSA undifferentiated (SSA-U, 17). The chief clinical and radiological features of the group were due to sacro-iliitis/spondylitis, peripheral arthritis and enthesopathy. Except for RS, extra-articular features were sparse. Mucosal lesions were not evident. Radiologically, sacro-iliitis varied from 24% in SSA-U to 100% in AS, and was disproportionately less when compared to its clinical extent. Dominant lower limb arthritis (poly and oligo) was seen in AS (40%), SSA-U (88.2%) and RS (100%). HLA A and B were typed in patients and controls. HLA AI had a significant negative association (p less than 0.05) with AS and the SSA group, and its relative risk (R) was consistently low (0.2-0.3). HLA B27 was present in 65.7%, 73%, 67%, 41% and 9% of the SSA group, AS, RS, SSA-U and controls respectively (p less than 0.05). Significant R values of A and B loci antigens in disease groups are presented. When compared with available Indian literature, this study highlights the variability and overlap in the disease. Disease markers currently available have limitations in defining the various subsets of SSA.

We have generated several human alloreactive cytolytic T lymphocyte (CTL) clones specific for HLA B27 expressed on cells of normals or of patients with ankylosing spondylitis (AS). These clonal T cell reagents were used to test the recognition of panels of target cells from B27+AS+, B27+AS- and B27- individuals. None of these CTL clones distinguished differences between B27+AS+ and B27+AS- cells. Three clones recognized subtypes of HLA B27 and two of these were cytolytic with group-reactive epitopes of other HLA antigens. The results suggest that there are no immunogenic disease-specific epitopes of HLA B27 in B27-linked spondyloarthropathy.

A 53-year-old man affected by ankylosing spondylitis associated with psoriasis developed bilateral tarsal tunnel syndrome caused by synovitis of the accompanying sheaths of the tendons that run through the 'fibro-osseous tunnel'. This report confirms the hypothesis that the tarsal tunnel syndrome may be a clinical manifestation of seronegative spondyloarthropathy.

In order to evaluate the frequency of subclinical gut involvement in the seronegative spondylarthropathies, ileocolonoscopy with biopsies of the colon, ileocecal valve and ileum were performed on 211 patients with ankylosing spondylitis (AS), reactive arthritis (ReA) and undifferentiated spondylarthropathies. Inflammatory gut lesions were detected in a large number of these patients. It was concluded that the group of undifferentiated spondylarthropathies could be split into fairly equal subgroups: one subgroup suffering from subclinical inflammatory bowel disease associated with peripheral joint symptoms, a second subgroup presenting a form of enterogenic ReA, and a third subgroup in which no relation with the gut could be demonstrated. Ankylosing spondylitis, which has to be considered as a form of undifferentiated seronegative spondylarthropathy, could be subdivided into the same subgroups. These findings confirm the existence of subclinical gut involvement in patients with seronegative spondylarthropathies.

A prospective endoscopic and histologic study of terminal ileum and colorectum in 211 patients with seronegative spondylarthropathy revealed macroscopic inflammatory lesions varying from erythema to superficial erosions in 30% of the patients and microscopic inflammation in 61%. Two types of inflammation were observed: an acute inflammation resembling an infectious enterocolitis and a chronic inflammation. In idiopathic reactive arthritis both types of inflammation were equally present, whereas chronic inflammation predominated in patients with ankylosing spondylitis. In 32% of patients with chronic inflammation, the lesions particularly resembled early Crohn's disease. Repeat ileocolonscopy on 19 patients demonstrated a parallel evolution of joint symptoms and histologic lesions. All patients with acute inflammation went into clinical and histologic remission, whereas lesions persisted in patients with Crohn-like inflammation. In patients with chronic inflammation, remission and persistence were observed equally. This study identified a group of patients with seronegative spondylarthropathy which, even in the absence of gastrointestinal symptoms, showed evidence of gut inflammation, probably inducing an increased gut permeability with transgression of the oral tolerance and absorption of provocative antigens into the circulation. It is also possible that both diseases reflect a common underlying process.

The postulated role of infectious agents, genetic susceptibility of the host to infection and their interaction in the pathogenesis of ankylosing spondylitis, other spondyloarthropathies, and the associated primary (non-arthritic) diseases are reviewed. Compared with a local control population there is a significantly increased prevalence of non-secretors amongst different groups of patients with spondyloarthropathy: ankylosing spondylitis, reactive arthritis and psoriatic arthropathy. No differences between secretor and non-secretor patients with respect to serum and salivary IgA levels, the occurrence of eye lesions or peripheral joint disease have been found. There is no evidence that ankylosing spondylitis or other spondyloarthropathies are associated with any particular ABO blood group. The association between non-secretion and ankylosing spondylitis strengthens the hypothesis that ankylosing spondylitis has an infective aetiology. It also suggests several pathogenetic mechanisms which may be relevant to the initial host-parasite interactions in the spondyloarthropathies.
