During episodes of acute anterior uveitis, patients had a T-lymphopenia and a temporary increase in B-lymphocytes. The T-lymphopenia was not present in patients investigated early in their first attacks, and it persisted after the patients recovered clinically. In household contacts of patients with uveitis, there was a temporary T-lymphopenia. A similar degree of T-lymphopenia was present in patients with ankylosing spondylitis who had not had uveitis, but not in their household contacts. In patients with spondylitis, there was no greater reduction of T-cells when they had episodes of uveitis. In all groups of subjects studied, T-lymphopenia could be abolished, in vitro, with thymosin, a bovine thymic-hormone estract. The finding of T-lymphocyte depletion in the contacts of uveitis patients, as well as in the patients themselves, suggests that there may be lateral transmission of an infective agent (or agents) in the households during (or before) attacks of uveitis.

The ocular and systemic characteristics of 160 patients with anterior uveitis and seronegative juvenile rheumatoid arthritis are reviewed. Chronic uveitis occurred in 131 patients, 76% of whom were girls. Both eyes were involved in 70% of the cases. Band keratopathy occurred in 41% of the eyes, cataract in 42%, and secondary glaucoma in 19%. Only 11 patients had uveitis before the onset of arthritis. Notable correlations included a pauciarticular onset of arthritis in 95% of the patients, and positive tests for antinuclear antibody in 82%. Of 29 patients with acute anterior uveitis, 27 were boys. The inflammation responded well to therapy, and serious complications did not occur. At follow-up 21 patients had typical ankylosing spondylitis, and five had sacroiliitis. The incidence of positive results of tests for HLA-B27 antigen was 94%.

As part of a larger study undertaken to determine whether the presence of faecal Klebsiella aerogenes was significantly associated with the clinical activity of ankylosing spondylitis, thirteen patients with ankylosing spondylitis and acute non-granulomatous anterior uveitis (ANGAU) were examined. The faeces of eleven of these thirteen patients were found to contain Klebsiella aerogenes. This association shows a statistical significance of P less than 0.01, and suggests that Klebsiella aerogenes may have an aetiological role in the development of anterior uveitis in HLA B27 positive patients. The possible mechanism of this association and its potential clinical significance are discussed.

The radiological manifestations of 200 patients with ankylosing spondylitis were appraised, and correlated with the patient's sex, anterior uveitis, and HLA B27. Radiological findings in female patients were no different from male patients. Only syndesmophyte formation in the spine was found significantly more frequently in patients with uveitis and HLA B27. Osteoporosis of the spine correlated strongly with a later age of onset, longer duration of the disease, older age at the time of study, Romanus lesions, syndesmophytes, spinal fusion, osteitis pubis, and widespread radiological destructive peripheral joint disease. Syndesmophytes were most frequently present at the dorso-lumbar junction. Spondylodiscitis was present in 8 patients and was most commonly present in the thoracic spine.

The clinical features of ankylosing spondylitis (AS) were compared in 63 HLA-B 27 positive (+) and 15 B27 negative (-) individuals with this disease. There were no differences in age at onset, functional class, degree of deformity, pain, severity of X-ray changes, or frequency of peripheral joint involvement or of reconstructive orthopedic surgery. These data demonstrated that skeletal manifestations of AS were essentially the same in B27(+) and (-) patients, and provide no evidence for the speculation that AS in B27(-) patients is milder or is a different disease from that occurring in B27(+) patients. On the other hand, acute anterior uveitis was found to be significantly more common in B27(+) patients, a fact suggesting that the "uveitis of AS" may in fact be an independent condition occurring in B27(+) individuals, rather than a manifestation of AS per se.

The histocompatibility antigen HLA-B27 was identified in 12 out of 33 patients with acute non-granulomatous anterior uveitis. This is a frequency of 36.36%, compared with 4.72% in controls. Seven patients had in addition evidence of systemic disease, including ankylosing spondylitis, sacroiliitis, Reiter's disease, Still's disease, and rheumatoid arthritis. Five of these were HLA-B27 positive, which suggests that the uveitis in many of these cases has a similar aetiology to the uveitis in those with rheumatic disease. It appears that the more severe cases of acute anterior uveitis are related more frequently to the presence of HLA-B27.

The tiysue antigen HLA-B27 was present in 92.6% of 95 Swiss patients with classical ankylosing spondylitis. This tissue antigen is present in only 7.7% of healthy Swiss blood donors. 36% of all patients had one or several acute attacks of anterior uveitis. This usually follows the onset of joint symptoms. In 4% of the 95 patients the iritis was the first symptom. The combination of acute uveitis and ankylosing spondylitis with the tissue antigen HLA-B27 indicates that not only the spondylitis, but also the uveitis is in many cases genetically determined.

The occurrence of acute anterior uveitis in ankylosing spondylitis was compared in 53 HLA-B 27 positive and 12 HLA-B 27 negative patients with this disease. Uveitis was found in HLA-B 27 positive patients only. These results suggest that uveitis and ankylosing spondylitis are independent diseases occurring on their own and strongly associated with HLA-B 27.

HLA-B27 is a transplantation antigen found in a high proportion of patients with ankylosing spondylitis. Recently, an association has been shown to exist between HLA-B27 and acute uveitis, even in the absence of ankylosing spondylitis. We have examined the HLA antigen profile of 45 patients with acute nongranulomatous anterior uveitis and have confirmed this relation. In addition, using 90mtechnetium stannous pyrophosphate we have been able to demonstrate abnormal bone scan in 19 of 30 patients studied. Such abnormalities are limited to the sacroiliac joints but are otherwise the same as those seen in overt ankylosing spondylitis. Seven of the 19 patients did not have HLA-B27. These factors suggest that acute anterior uveitis may often represent a manifestation of a spondylitic diathesis even in the complete absence of any suggestive symptomatic or radiologic change and, in some cases, even though the antigenic marker HLA-B27 may be absent.

51 (30 men and 21 women) of 90 consecutive patients with acute non-granulomatous anterior uveitis were HL-A 27 positive. This frequency of 55-7 per cent compares with 8-2 per cent in controls. Twenty-three patients (18 men and 5 women) had in addition evidence of systemic disease, including ankylosing spondylitis, sacroiliitis and Reiter's syndrome, sometimes associated with psoriasis. Twenty-eight of 63 patients without evidence of systemic disease were HL-A 27 positive, suggesting that the uveitis in many of these cases has a similar aetiology to those with rheumatic disease. The uveitis associated with HL-A 27 is typically unilateral, associated with mechanical ptosis, and a painful diffusely red, photophobic, and lacrimating eye, generally lasting 3 weeks or more. Protein extravasation into the aqueous is considerable, cells are usually present in the aqueous and anterior vitreous, and keratic precipitates are never mutton fat in appearance. Recurrent episodes are characteristic. The association with HL-A 27 suggests that many if not most cases of non-granulomatous anterior uveitis have a close aetiological relationship to ankylosing spondylitis and Reiter's syndrome and it is likely that infective agents, leading to an unusual immunologically mediated inflammatory response in predisposed individuals, are involved. Ten patients with granulomatous anterior uveitis were HL-A 27 negative.
