A review of rheumatic diseases in the southeast coastal Indians of Alaska revealed high frequencies of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Both prevalence and incidence rates of RA were significantly higher and the peak age of incidence was younger in the southeast Alaskan Indian population than in Alaskan Eskimo groups and the United States population in general. The prevalence of SLE in the Alaskan Indian population was about twice that reported for most white populations. The frequency of seronegative spondyloarthropathic disorders was similar in the Alaskan Indian and Eskimo populations. Comparable studies of the prevalence of spondyloarthropathy in general have not been carried out in white populations. The prevalence rate of ankylosing spondylitis, one of the major types of spondyloarthropathy, did not differ significantly in the SE Indians from rates in predominantly white US populations.

Ileocolonoscopy was performed on 354 patients with spondyloarthropathies. Histologically, the population could be divided into 145 patients with normal gut histology, 88 patients with acute inflammatory lesions and 121 patients with chronic inflammatory lesions. A number of clinical, biologic, radiologic and genetic variables were determined before ileocolonoscopy. Chronic gut lesions were associated with a family history of ankylosing spondylitis (AS) and Crohn's disease, several episodes of diarrhea, an increased stool frequency, elevated inflammatory serum variables, reduced axial mobility, the presence of sacroiliitis, bamboo spine, destructive joint lesions, a diagnosis of AS and HLA-Bw62 positivity. As the frequency of HLA-Bw62 is also increased in proven Crohn's disease, this would suggest that chronic gut lesions are related to this disease. Acute inflammatory lesions were related to a higher fecal carriage of specific bacteria and to the diagnosis of undifferentiated spondyloarthropathy, especially the enterogenic forms of reactive arthritis. Consequently, these lesions also appear to be related to a bacterially induced gut inflammation. Gut histology was normal in urogenital inflammation and urogenital reactive arthritis, suggesting a different portal of entry for antigens. The 3 histologic pictures of the gut (normal, acute and chronic) inflammation seem to correlate with different clinical, biologic and radiologic manifestations of the disease concept of spondyloarthropathies.

The authors reviewed the files of male patients who have been hospitalized over a 12 year period for a rheumatoid-factor negative arthritis beginning after age 50. Polymyalgia rheumatica, psoriasis or crystal-induced arthritis were excluded. The remaining 105 observations were classified according to published criteria in rheumatoid arthritis (RA), reactive arthritis or ankylosing spondylitis (AS). Twenty-nine patients had RA and 29 had AS with equal numbers of axial and peripheral types. Four patients had reactive arthritis, one of them had also AS. Forty-four patients had "unclassified arthritis". Among the latter, 14 were B27 positive, 21 were B27 negative, 9 were not typed. Some features were more frequent in B27+ patients: an assymetrical oligoarthritis of the lower limbs with minimal signs of inflammation at synovial analysis or at synovial biopsy; frequent unilateral edema; marked, constitutional signs; very high ESR. Nine patients, all B27+, met the diagnostic criteria of spondylarthropathy. B27 typing thus appears relevant to the classification of late-onset, seronegative rhumatisms.

A survey was conducted to determine the frequency and semiological characteristics of spondylarthropathies seen during hospital consultation in Lome, Togo. Spondylarthropathy was diagnosed in 13 of 1498 consulting patients. All were male and ranged in age from 18 to 44 at the onset of the disease. 6 patients suffering from ankylosing spondylitis had bilateral sacroiliitis--5 were HIV positive and had no signs of sacroiliitis on pelvic x-rays and the remaining 2 were HIV negative and had no sacroiliitis. HLA typing was not carried out in any patient. The symptoms of ankylosing spondylitis in these patients were comparable to those of European patients. The symptoms of HIV-positive patients were reminiscent of those describing reactive arthritis in such patients. The results of this study contradict the reputed scarcity of ankylosing spondylitis and other spondylarthropathies in black Africa. HIV infection may increase the incidence of reactive arthritis and, as a consequence, that of spondylarthropathies in this region. (author's)

Classification criteria for most of the disorders belonging to the spondylarthropathy group already exist. However, the spectrum of spondylarthropathy is wider than the sum of these disorders suggests. Seronegative oligoarthritis, dactylitis or polyarthritis of the lower extremities, heel pain due to enthesitis, and other undifferentiated cases of spondylarthropathy have been ignored in epidemiologic studies because of the inadequacy of existing criteria. In order to define classification criteria that also encompass patients with undifferentiated spondylarthropathy, we studied 403 patients with all forms of spondylarthropathy and 674 control patients with other rheumatic diseases. The diagnoses were based on the local clinical expert's opinion. The 403 patients included 168 with ankylosing spondylitis, 68 with psoriatic arthritis, 41 with reactive arthritis, 17 with inflammatory bowel disease and arthritis, and 109 with unclassified spondylarthropathy. Based on statistical analysis and clinical reasoning, we propose the following classification criteria for spondylarthropathy: inflammatory spinal pain or synovitis (asymmetric or predominantly in the lower limbs), together with at least 1 of the following: positive family history, psoriasis, inflammatory bowel disease, urethritis, or acute diarrhea, alternating buttock pain, enthesopathy, or sacroiliitis as determined from radiography of the pelvic region. These criteria resulted in a sensitivity of 87% and a specificity of 87%. The proposed classification criteria are easy to apply in clinical practice and performed well in all 7 participating centers. However, we regard them as preliminary until they have been further evaluated in other settings.

A 53-year-old man with a 20-year history of ankylosing spondylitis presented with proteinuria and acute renal insufficiency. Amyloidosis was diagnosed on renal biopsy. The association of secondary amyloidosis has been described with collagen vascular diseases, however, a review of the literature reveals few cases associated with the spondyloarthropathies. We were able to find only 2 cases in the American literature. Thus, although a rare complication, amyloidosis should be considered in the differential diagnosis of proteinuria and renal insufficiency in spondyloarthropathy.

Inflammatory eye disease is well recognized in ankylosing spondylitis (AS) but the relationship between the uveitis and the spondyloarthropathy is poorly defined. The following conclusions may be drawn from a study of 1331 consecutive patients with AS: the prevalence of uveitis was 40% (535 subjects), almost half of whom had greater than 5 attacks. Family studies of sib pairs, concordant for AS, showed that uveitis occurred randomly with a concordance for uveitis/no uveitis of only 43%. A comparison of patients with (n = 535) and without (n = 796) uveitis showed no important differences. Analysis of potential trigger factors among 72 patients with recurrent disease revealed no seasonal, infective or other correlation. The removal of an intrauterine device from a woman with severe intractable bilateral uveitis was associated with remission of the eye disease. In summary, although genetic background determines susceptibility to uveitis the pattern of the disease suggests the possibility of random environmental triggers unrelated to the course of the underlying rheumatological disorder.

A set of early diagnostic (ED) criteria comprising clinical data, ESR, radiological spinal signs, and the risk factor HLA B27 was evaluated after 5 and 10 years in a follow-up of 54 patients with an initial diagnosis of possible ankylosing spondylitis (AS). After 10 years 32 patients (59%) had developed definite AS according to the New York criteria, 10 individuals (19%) had possible or undifferentiated spondylarthropathy (SA), whereas in 12 patients (22%) other diagnoses were stated. ED criteria had a high discriminatory significance for the development of AS after 5 and 10 years (P less than 0.005, P less than 0.001 respectively). In this respect they were more valuable than B27 determination alone (P less than 0.01) or the ED criteria without HLA B27 (P less than 0.05). Furthermore, patients with still possible or undifferentiated SA had a higher mean score at the first examination than individuals with other final diagnosis (P less than 0.05). Thus, the ED criteria were useful for the identification of patients developing definite AS and of individuals in the AS related group of possible or undifferentiated SA.

We previously reported elevated serum antibody levels to a peptide representing the HLA-B27 polymorphic region (B27 peptide) in HLA-B27(+) ankylosing spondylitis (AS) patients. A plasmid (pHS-2) isolated from arthritogenic Shigella flexneri strains had been shown to encode an amino acid sequence homologous to HLA-B27. Rabbit antibody to this sequence (pHS-2 peptide) strongly cross-reacted with B27 peptide and, to a much lesser extent, with Klebsiella nitrogenase peptide. Serum antibody levels to pHS-2 peptide were studied in 160 spondylarthropathy patients. 12 of 115 (10.4%) AS patients, 2 of 45 (4.4%) patients with Reiter's syndrome or reactive arthritis as well as 6 of 147 (4.1%) normal controls were shown to have elevated anti-pHS-2 peptide antibodies. Antibody levels to B27 and pHS-2 peptides were significantly correlated in 134 HLA-B27(+) patients (r = 0.333, P less than 0.001). 13 of 15 affinity-purified anti-B27 peptide antibodies from patients strongly cross-reacted with pHS-2 peptide, whereas only 3 weakly cross-reacted to nitrogenase peptide. Leucine appeared to be a critical residue for this cross-reaction. AS patients' anti-B27 peptide antibodies reacted with HLA-B27 transfected L cells. These results may suggest that pHS-2 peptide more efficiently "mimics" B27 peptide than does nitrogenase peptide. Involvement of pHS-2 in pathogenesis of spondylarthropathy through molecular mimicry mechanisms requires further study.

As in other diseases of undetermined etiology, the diagnosis of ankylosing spondylitis (AS) and related spondyloarthropathies (SpA) is based on clinical and roentgenographic features. The current criteria for diagnosis of some of these diseases are too restricted, and do not recognize the existence of a much wider disease spectrum. For example, radiographically detected sacroiliitis is extremely frequent in AS, but may not be an obligate manifestation, especially in early or atypical forms of the disease. Arthritis involving the axial skeleton, including the sacroiliac joints, can be present in some patients without evidence of erosive disease roentgenographically. The disease spectrum of Reiter's syndrome has also been broadened considerably, and "incomplete" forms of Reiter's syndrome are observed much more commonly than the classical triad of arthritis, conjunctivitis, and urethritis. The term "B27-associated reactive arthritis" has been used in recent years to refer to SpA following enteric or urogenital infections, and the disease spectrum includes the clinical picture of typical Reiter's syndrome. The clinical spectrum of psoriatic SpA has been better clarified. Some of the less well defined B27-associated clinical syndromes include seronegative oligoarthritis, polyarthritis, or dactylitis ("sausagelike" toes) of the lower extremities, and heel pain caused by calcaneal (and tarsal) periostitis. These and other undifferentiated SpA have been ignored in previous epidemiological studies because of the inadequacy of the existing classification criteria. The European Spondylarthropathy Study Group (ESSG) has completed a study aimed at developing preliminary classification criteria for the whole group of SpA patients, with the specific intention of encompassing patients with undifferentiated SpA.
