IgA antibodies to Klebsiella pneumoniae var oxytoca and Proteus mirabilis were measured in 66 patients with ankylosing spondylitis (AS) and 31 with rheumatoid arthritis (RA) and in 51 healthy control subjects, using an immunoblotting technique. The number of antigenic bands to klebsiella on nitrocellulose membrane was higher in 28 patients with active AS than in 38 patients with inactive AS, 31 patients with RA, and 51 healthy control subjects; comparatively smaller increases were found against proteus. In two patients with AS the synovial fluid and the corresponding serum sample showed an identical antibody pattern. Increases in IgA antibodies to klebsiella in patients with AS confirm previous studies using other techniques.

One hundred and fourteen patients with acute anterior uveitis were studied for the presence of the HLA-B27 tissue type, the prevalence of spondylitis and arthritis and the occurrence of gastro-intestinal and urogenital infections or diarrhoeal illness in the history. Eighty-seven (76%) were B27+ and 27 (24%) B27-. Forty-two (48%) of the B27+ group had ankylosing spondylitis (AS); 13 (30%) of them were females. Sacroilitis (SI) with no spinal involvement was present in 21 patients (24%), 13 (61%) males and 8 (38%) females. Peripheral arthritis occurred in 6 patients. Thus, 68 (78%) of the HLA-B27+ positive patients had inflammatory spinal and/or joint disease, compared with 1 (4%) of the HLA-B27- group (p less than 0.001). The AS diagnosis was unknown previous to our examination in 31% of the males and 54% of the females, and SI was undiscovered in 61% of the males and 62% of the females. The occurrence of acute enteric infections was significantly increased in the B27+ AAU group, compared with the B27- patients and the patients reported exacerbation of AAU in connection with episodes of diarrhoea. An increased occurrence of urogenital infections was shown only in co-comparison with the males of the B-27+ AAU group. Thirty-three out of 47 AAU patients assayed by enzyme immuno-assay (EIA) for the quantification of IgM, IgA and IgG antibodies against Klebsiella pneumoniae, E coli, and Proteus mirabilis had significantly raised antibody titres against one or more of the antibodies studied, as compared to 62 healthy controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Antibodies to Salmonellae, Yersiniae, Campylobacter jejuni, Borrelia burgdorferi, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis and Chlamydia trachomatis were measured by ELISA in the sera of 99 patients with ankylosing spondylitis. Increased prevalence of IgA and IgG class antibodies against K. pneumoniae and of IgA class against E. coli was observed in ankylosing spondylitis. No clear correlation between the disease activity and occurrence of antibodies was revealed. The results are in line with the previously published findings suggesting that K. pneumoniae may have a role in the aetiopathogenesis of ankylosing spondylitis.

ELISA quantitation of antibodies to Klebsiella pneumonia, Proteus mirabilis, and Yersinia enterocolitica was conducted in 75 ankylosing spondylitis (AS), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) probands and in 262 of their first-degree relatives. The control group comprised 28 healthy donors. Sixteen (64 per cent) AS probands (12 with B27+) and 26 (30.2 per cent) their relatives (14 with B27+) were found to have high titres of antibodies to Klebsiella pneumonia. In 18 (60 per cent) active RA probands and 27 (23.7 per cent) relatives, antibodies to Proteus mirabilis were found. The obtained results suggest the presence of genetic determinants of the increased immune response to various infectious agents, at least in the AS cases. The possibility of Enterobacteriaceae acting as polyclonal stimulators is not excluded.

Antibodies to proteus species were measured in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and in healthy controls by a Coombs agglutination method. The titres to Proteus mirabilis were higher in 30 RA patients being treated with gold than in 24 patients with active AS (p less than 0.001), 28 patients with inactive AS (p less than 0.001), and 41 healthy control subjects (p less than 0.001). Control studies with Klebsiella pneumoniae var oxytoca showed high antibody titres only in active AS patients.

Antibodies to Klebsiella, but not to other bacteria, have been shown to be present in patients with active ankylosing spondylitis (AS) by seven different techniques. Antibodies to Proteus, but not to E. coli or Klebsiella, have been shown to be present in patients with active rheumatoid arthritis (RA) by three different techniques. It is suggested AS and RA are forms of reactive arthritis, to Klebsiella and Proteus respectively, probably mediated by cross-reactivity to HLA antigens.

Antibodies to Klebsiella oxytoca and Proteus mirabilis in 21 active ankylosing spondylitis (AS), 13 active rheumatoid arthritis (RA), 19 inactive RA patients and 18 healthy controls were measured using enzyme-linked immunosorbent assay (ELISA). Elevated anti-Klebsiella antibodies were demonstrated in active AS patients compared to active RA (p less than 0.01), inactive RA patients (p less than 0.001) and controls (p less than 0.005). When measuring antibodies to Proteus, active RA patients showed higher levels of antibodies compared to active AS patients (p less than 0.005) and healthy controls (p less than 0.05). Further investigations are required to assess the role of Klebsiella and Proteus microorganisms in AS and RA respectively.

IgM, IgG and IgA class serum antibodies against the whole Klebsiella pneumoniae, Escherichia coli and Proteus mirabilis bacteria, as well as against K. pneumoniae and E. coli lipopolysaccharides (LPSs) were studied earlier in two separate patient populations of 99 and 85 patients with ankylosing spondylitis (AS) and in 102 healthy blood donors by enzyme immunoassay. In this study the patients were divided into groups according to the presence or absence of peripheral arthritis. The patients with peripheral type AS had increased levels of IgM and IgA class antibodies against K. pneumoniae, whereas the patients with axial type AS had increased levels of IgG and IgA class antibodies to K. pneumoniae, as well as IgA class antibodies against E. coli and P. mirabilis bacteria. Sulphasalazine treatment decreased the IgM and IgA class antibodies in peripheral AS and IgA class antibodies in axial AS against K. pneumoniae LPS. The antibody levels were also decreased against E. coli and P. mirabilis bacteria in the sera of patients with axial AS. The immunological findings in patients with peripheral and axial form of AS were different from each other and thus may reflect different aetiopathogenetic mechanisms for these two types of AS.

IgM, IgG and IgA class serum antibodies against the whole Klebsiella pneumoniae, Escherichia coli and Proteus mirabilis bacteria, as well as against K. pneumoniae and E. coli lipopolysaccharides (LPSs) were studied earlier in the sera of 98 patients with ankylosing spondylitis (AS) and in 102 healthy blood donors by enzyme immunoassay. In this study the patients were divided into groups according to the clinical picture, i.e. presence or absence of iritis and enthesitis. The previous major finding of increased IgA class antibody levels against the whole K. pneumoniae bacteria in AS patients when compared to the healthy controls was not specifically associated with any single patient group in the present study. However, the patients with iritis had higher levels of IgA class antibodies to LPS of K. pneumoniae and E. coli when compared to the patients without iritis. In addition, the patients without enthesitis had higher level of IgG class antibodies against whole K. pneumoniae bacteria compared to the patients with enthesitis. The increased IgA class antibody levels against K. pneumoniae and E. coli LPS in AS patients with iritis may reflect an inflammatory process in the gut area. Furthermore, there were certain other differences in the immunological parameters between the AS patients with and without iritis or enthesitis and the possibility that they reflect different mechanisms involved in the disease processes cannot be excluded.

The bacteria Proteus, Serratia, Escherichia and Pseudomonas possess sequences resembling the rheumatoid arthritis susceptibility sequence EQRRAA, but antibodies were elevated only to Proteus in 66 RA patients (P<0.001) when compared to 61 active ankylosing spondylitis patients and 60 controls.
