The spondyloarthropathies of childhood present a diagnostic and therapeutic challenge. It is important to differentiate this group of arthritides from JRA because the nature and frequency of extra-articular complications are quite different, as is the prognosis and the therapeutic approach. JAS is the prototype of the spondyloarthropathies and probably accounts for greater than 75 per cent of all children with diseases included in this category. Unlike adult-onset ankylosing spondylitis, axial skeleton disease (sacroiliac, lumbar spine) is infrequent at onset of JAS and may not develop for months or years after the onset of arthritis in peripheral joints (particularly those of the lower extremity). Enthesitis, the inflammation of the insertion of tendon, capsule, ligament, or fascia to bone, is an important clinical diagnostic feature of this group of diseases. Extra-articular disease, such as rash in psoriatic arthritis, erythema nodosum, weight loss of abdominal pain (in the arthropathies of inflammatory bowel disease), urethritis, conjunctivitis, or Reiter's syndrome help to differentiate these spondyloarthropathies from JAS. Laboratory studies are of little assistance in differentiating JRA from the spondyloarthropathies except that in the latter group, RF is absent and HLA-B27 is frequently present. The high frequency of ANA in JRA contrasts with its corresponding low frequency in JAS. The long-term follow-up of chronic arthritis in childhood has demonstrated the variable and evolving nature of these conditions, and stresses the importance of continually questioning the accuracy of the diagnosis.

Radiologic assessment of the sacroiliac joints should be part of every inflammatory bowel disease patient's workup; ankylosing spondylitis is 10 to 20 times more common in ulcerative colitis patients than in normal persons. Iritis, which occurs in 10 to 20% of ulcerative colitis patients, often precedes bowel symptoms. It may be necessary to use long-term, low-dose steroid therapy to control frequently recurring iritis.

Two-dimensional echocardiographic findings of subaortic fibrous ridging, aortic leaflet thickening, and aortic root dilatation and thickening are described in a group of 36 patients with rheumatoid variant diseases. The group consisted of 25 patients with ankylosing spondylitis, nine patients with Reiter's syndrome, and two patients with inflammatory bowel disease and spondylitis. No patient had clinical or laboratory evidence of aortic regurgitation or heart block. Subaortic fibrous ridging or marked leaflet thickening was noted in 11 of 36 patients; in contrast, no such changes were found in an age-matched control group of 29 men. The subgroup of patients with subaortic fibrous ridging or leaflet thickening (11 patients) had significantly longer disease duration (28.1 versus 17.7 years) and higher incidence of aortic root echo-density (82 versus 36 percent) than the remaining patients. It is concluded that a significant portion of patients with ankylosing spondylitis or Reiter's syndrome have echocardiographic evidence of aortic root involvement prior to the clinical onset of aortic regurgitation.

Sacroiliac uptake ratios based on 99Tcm methylene diphosphonate images were calculated in 14 patients with ankylosing spondylitis, 23 patients with non-specific backache, 33 patients with inflammatory bowel disease (ulcerative colitis 19, Crohn's disease 14) and 33 control subjects. Twenty-eight of the control subjects were patients referred from a breast cancer clinic. In the control subjects, and in 20 patients with inflammatory bowel disease who did not have back pain, sacroiliac ratios decreased significantly with increasing age (p less than 0.001 and p less than 0.01 respectively). Sacroiliac uptake ratios were significantly higher in ankylosing spondylitis than in patients with non-specific backache. Seven of the 14 patients with ankylosing spondylitis had higher sacroiliac ratios than any recorded in the control subjects. Eleven patients with inflammatory bowel disease had abnormally high sacroiliac uptake ratios; ten of these patients had back pain. Increased sacroiliac joint uptake in such patients may reflect early sacroiliitis. No relationship was detected between sacroiliac uptake and the activity of the bowel disease. Sacroiliac uptake ratios were significantly higher in the inflammatory bowel disease patients suffering from back pain than in age and sex matched patients with (a) inflammatory bowel disease but no back pain or (b) non-specific backache.

Spondyloarthritis (Sp) is newly defined as arthritis that is clinically, pathologically, and genetically related to and predisposed to ankylosing spondylitis (AS) and Reiter's syndrome (RS) rather than to rheumatoid arthritis (RA). A diagnosis of Sp does not necessarily imply arthritis of the spine and does not depend on the demonstration of roentgenographic sacroiliitis that, in this conceptualization, is recognized not as the essential hallmark, but rather merely as a diagnostic "way station" on a continuum of disease, which may (but need not necessarily) begin with RS or be complicated during its course by AS or RS. Spondyloarthritis is distinctively characterized morphologically and clinically by disproportionate inflammation at the entheses, the sites of attachment of tendons and ligaments to bone. Family history or presence of enthesopathic pain, psoriasis, inflammatory bowel disease, uveitis, recurrent urethritis, prostatitis or cervicitis, keratoderma blennorrhagicum, HLA-B27, and asymmetric pauciarticular lower lower extremity arthritis without rheumatoid factor or rheumatoid nodules suggests a diagnosis of Sp rather than RA.

Of 12 patients with inflammatory bowel disease (IBD) and ankylosing spondylitis (AS) or sacroiliitis (SI), only 4 (32%) had HLA-B27. Family studies revealed 3 B27-negative relatives with AS, 1 with SI, 1 with SI and IBD, and 1 with IBD alone. HLA haplotypes did not segregate with disease. These data suggest a non-HLA linked genetic predisposition to IBD which also confers susceptibility to spondylitis, even in the absence of expression of bowel disease.

The erythrocyte sedimentation rate (ESR) was examined annually for 15 years in 1,000 asymptomatic men aged 18-33 years at entry into the study in 1968. The upper limit of the normal (mean + 2 SD) increased from 8 mm in the first hour in persons aged 18 years to 18 mm in those age 45. An increase in the ESR above the age adjusted upper limit of normal on at least three of four consecutive annual examinations was observed in 44 (4.4%) cases. The elevated ESR was associated with a diagnosed disorder in 10 of these 44 cases: myocardial infarctions (four), ankylosing spondylitis (three), inflammatory bowel disease (one), psoriasis (one), and "benign" monoclonal gammopathy (one). A persistently elevated ESR increased the likelihood of disease in general from 3.8% to 22.7% and of myocardial infarction from 0.7% to 9.1%. In eight patients the elevation of the ESR preceded the clinical manifestations by 2-10 years. It is concluded that a persistent moderate elevation in ESR detected in a young adult in the course of screening examinations is a risk factor for the development of disease.

The results of segregation analyses in 75 families where the proband had ankylosing spondylitis, are presented. Of the 278 adult, living first degree relatives, approximately 85% cooperated in the study. Clinical and radiographical examinations were performed and HLA typing was conducted. The results were in agreement with our hypothesis that ankylosing spondylitis is part of a syndrome where different genetic factors interact. Such known factors are HLA B27 associated disease susceptibility, susceptibility to psoriatic arthropathy and susceptibility to entero-arthropathy. Radiographical sacro-iliitis was restricted to HLA B27 positive relatives, and was more frequently found in relatives to probands with psoriasis than in relatives to probands without psoriasis. Environmental factors (intestinal bacteria) are known to trigger the disease at least in some persons, and we have postulated that all or most of them have the predisposition to develop disease. Thus, the syndrome has a multifactorial etiology. The phenotypic expressions of the different genetic predispositions involved, include sacro-iliitis, psoriasis, acute anterior uveitis, peripheral arthropathy and inflammatory bowel disease. We suggest the descriptive name HEREDITARY MULTIFOCAL RELAPSING INFLAMMATION (HEMRI) for this syndrome. Ankylosing spondylitis, psoriatic arthropathy and entero-arthropathy may be regarded as clinical sub-types of the syndrome.

The major histocompatibility complex on the sixth chromosome controls expression of a complex series of cell surface antigens which comprise the human leukocyte antigen (HLA) system. These markers, beyond their importance in human organ transplantation, have been demonstrated to occur with an increased prevalence in certain disease states. The group of conditions showing the closest association with specific HLA antigens are the "spondyloarthropathies." These include ankylosing spondylitis (AS), Reiter's syndrome (RS), psoriatic arthritis (PsA), and the arthritis of inflammatory bowel disease (AIBD). Clinical and radiographic studies were made of 310 unrelated caucasoid patients with seronegative arthritis. HLA-A, B, C, and DR typing were performed using the microdroplet lymphocyte cytotoxicity test. Statistically increased prevalences of A26, B27, and Bw38 were observed, while B27 was associated with spinal involvement regardless of diagnosis (90 percent in AS p less than 0.0001). Experiments found A26 (23 percent p less than 0.001) and Bw38 (38 percent p less than 0.0001) in patients with PsA. Spondyloarthritis patients with spinal involvement who lacked B27 frequently had B7. The HLA DR typing for seven specificities was carried out in 196 patients. It was found that DRw4 (52 percent p less than 0.03) and DRw7 (39 percent p less than 0.04) were increased in the PsA patients. This study further confirms the close association of HLA antigens and the spondylarthropathies.

Data of 46 patients with juvenile chronic arthritis were evaluated. All of them were under the age of 16 at the time of study. Patients with juvenile ankylosing spondylitis, psoriatic arthritis, and arthritis associated with inflammatory bowel disease were excluded from this series. Twenty-six patients had pauciarticular, 9 had systemic, 8 had polyarticular, and 3 patients had seropositive 'adult type' JCA. In all patient groups IgG, IgM, IgA, and C3 levels were significantly higher than in the control group. None of the controls but 13 of 46 patients had high IgE levels. IgA and IgG values were significantly higher in the seropositive subgroup than in the pauciarticular subgroup. There was no other positive correlation between levels of immunoglobulins, C3, and clinical features of disease. Platelet counts were significantly higher in patients with active disease. In the control group 4 out of 10 children had 'hidden' rheumatoid factor. All these children with positive findings were young.
