In 40 distal ileal and 40 colonic biopsies of arthritic patients mostly without gastrointestinal symptoms, but with histological evidence of acute or chronic inflammation of the gut, the number of immunoglobulin (Ig) containing plasma cells was studied morphometrically using a
peroxidase
antiperoxidase technique. Compared with controls, the ileal mucosal biopsies showed an increase of IgA and IgG in acute ileitis. In chronic ileitis there was an increase of IgA, IgG, and IgM similar to Crohn's disease. In colonic biopsies there was a significant increase of all immunoglobulin classes in acute inflammation. In chronic inflamed mucosa there was also an increase of all three Ig classes. The Ig distribution, however, was significantly different in acute and chronic colitis. These findings give immunohistochemical evidence of the existence of two different types of inflammation related to reactive arthritis or the peripheral joint involvement of
ankylosing spondylitis
. The Ig pattern in acute colitis is similar to that found in infectious colitis, suggesting an enterobacterial origin of the arthritis in this group of patients although bacteriological and serological investigations were negative. In the chronic type of arthritis related ileocolitis, the pattern of Ig containing cells is similar to that found in Crohn's disease but different from infectious and ulcerative colitis, which makes the hypothesis that a great number of these arthritis patients suffer from asymptomatic or subclinical Crohn's disease acceptable.

Patients suffering from rheumatoid arthritis, spondylosis, coxarthrosis,
ankylosing spondylitis
, chronic active and chronic alcoholic hepatitis were studied. The plasma vitamin E content remained unchanged. The TBA-reactive plasma substances (malondialdehyde) content of plasma increased in all patients except those with
ankylosing spondylitis
. Catalase activity of plasma increased in patients of both sexes suffering from rheumatoid arthritis and spondylosis and coxarthrosis, but decreased in the two hepatitis groups. The glutathione-
peroxidase
activity of RBC (1:9 haemolysate) increased in female rheumatoid arthritis patients and decreased in those suffering from chronic alcoholic hepatitis. The results showed that chronic inflammatory processes affect the rate of lipid peroxidation and the activity of the biological antioxidant mechanism.

Thirteen haematological parameters were measured in 44 patients with rheumatoid arthritis (RA) and 39 disease control patients with
ankylosing spondylitis
(AS). Using a 10 000 cells per sample automated differential counter the most frequent abnormalities found were monocytopenia, low numbers of large unstained cells, basophilia and increased numbers of cells with high
peroxidase
activity (HPX). The total white cell count, lymphocyte and monocyte counts, the HPX count, platelet distribution width and erythrocyte sedimentation rate were able to distinguish RA from AS at a statistically significant level. Discriminant function analysis showed that a maximum of 55% of RA patients could be correctly classified into disease state when combinations of six out of seven laboratory tests were used.

The histological features of the synovial membrane in rheumatoid arthritis (RA) are shared by other chronic inflammatory joint diseases, so that diagnostic differentiation is impossible. Examination of the immunoglobulin class in the plasma cells present in inflamed synovial membranes, however, has shown differences. Synovial membranes from 12 patients were seropositive RA, eight with seronegative RA, eight with
ankylosing spondylitis
, five with psoriatic arthritis, and three with Reiter's syndrome have been compared by
peroxidase
-antiperoxidase (PAP) staining for immunoglobulin classes on routinely paraffin wax embedded sections. There were no significant differences in the percentages of plasma cells containing IgG of IgA between the diseases studied. There were, however, significantly more plasma cells containing IgM in patients with seropositive RA (2-34%) compared with those with seronegative RA (0-10%; p less than 0.002) and with other chronic synovitides (0-9%; p less than 0.002). The results show that it is possible to distinguish seropositive RA from other chronic inflammatory joint diseases by PAP staining for immunoglobulin classes in the plasma cells present in the inflamed synovial membrane.

Antibodies to beta 2 microglobulin are found in systemic lupus erythematosus patients and are important in the lymphocytotoxic reactions of sera from such patients. In this study, beta 2 microglobulin antibodies were measured with the use of an enzyme-linked immunosorbent assay with purified beta 2 microglobulin antigen and
peroxidase
-labeled anti-human IgG or IgM. IgG antibodies to beta 2 microglobulin were found in 68% of 22 patients with
ankylosing spondylitis
. This incidence was higher than the 5% in 80 controls (P less than 0.01) and similar to the 71% incidence found in 35 patients with systemic lupus erythematosus. Eleven (27%) of 41 patients with rheumatoid arthritis had elevated levels of antibodies to beta 2 microglobulin (P less than 0.01). The mean antibody levels expressed in enzyme units were 0.125 for patients with
ankylosing spondylitis
, 0.157 for those with systemic lupus erythematosus, 0.101 for those with rheumatoid arthritis, and 0.067 for controls. IgM anti-beta 2 microglobulin was not significantly different from controls. A competitive binding assay with enzyme-labeled beta 2 microglobulin was used to determine serum beta 2 microglobulin. These values were also found to be elevated in 48% of patients in all 3 disease categories (P less than 0.01). Beta 2 microglobulin antibodies and serum beta 2 microglobulin did not correlate with each other, renal diseases or antinuclear antibodies in patients with systemic lupus erythematosus, with rheumatoid factor or severity of articular disease in patients with rheumatoid arthritis, or with peripheral arthritis or iritis in those with
ankylosing spondylitis
. Although antibodies to beta 2 microglobulin might reflect a general disturbance of immune regulation in patients with systemic lupus erythematosus, their presence in those with
ankylosing spondylitis
, a disease closely associated with a specific HLA allotype and not usually associated with formation of autoantibody, suggests that they might play a role in the pathogenesis of the latter disease.

The localisation of fibronectin in the synovial membrane of rheumatoid arthritis (RA) and other chronic inflammatory joint diseases has been studied using a
peroxidase
-antiperoxidase immunohistochemical method. Synovia were studied from seven cases of seropositive RA three cases of seronegative RA, six cases of
ankylosing spondylitis
, four cases of Reiter's syndrome and five of psoriatic arthritis. Six were small biopsies and the remaining tissues were obtained at open surgery for orthopaedic procedures or biopsies. Fibronectin was demonstrated in all of the synovia examined and was present in intimal cells, synovial giant cells, the walls of small blood vessels, basement membrane of larger vessels and deposits of fibrin. No difference in this distribution of fibronectin was found in seropositive and seronegative RA,
ankylosing spondylitis
, Reiter's syndrome or psoriatic arthritis, neither was there any difference in the amount of fibronectin at various sites.

A pituitary mass was found at necropsy of a male Macaca mulatta. Hematoxylin and eosin-stained sections were consistent with a chromophobe adenoma. Ultrastructural examination revealed the tumor to be comprised predominantly of sparsely granulated cells. The tumor cells were negative for prolactin, somatotropin, adrenocorticotropin, luteinizing hormone, and thyrotropin by the
peroxidase
anti-
peroxidase
method. Other major lesions were gynecomastia and galactorrhea, testicular atrophy,
ankylosing spondylitis
, and amyloid deposition in the liver, spleen, adrenal, and intestinal tract.

A study of cell immunity was carried out in 23 patients with
ankylosing spondylitis
, 17 HLA B27 +, 6 HLA B27 --, 5 donors of normal blood carrying HLA B27 antigen and 50 controls, 7 methods were used together for a study of the markers of the blood lymphocyte membranes: rosette E, rapid rosette E, anti HTLA + X, surface immunoglobulins, PEA gamma and BEA gamma rosettes, determination of the monocytes after
peroxidase
staining. Stimulation of lymphocytes with mitogens (PHA, Con A, PWM) were carried out. There exists an increase in blood lymphocytes carrying HTLA + X in patients with
ankylosing spondylitis
HLA B27 and also in healthy carriers of the same antigen. During
ankylosing spondylitis
with HLA B27 --, a statistically significant reduction in T lymphocytes forming E and E rapid rosettes was observed; finally, a rise in the levels of circulating immune complexes detected by the PEG --C4 method was noted. The significance of these facts is discussed.

We studied the presence of proteinase 3 (PR3),
myeloperoxidase
(
MPO
) and elastase (HLE) on the plasma membrane of neutrophils in patients with biopsy-proven Wegener's disease (WG), pANCA-positive vasculitis, control patients (SLE, rheumatoid arthritis,
ankylosing spondylitis
), sepsis patients and healthy donors. We found an overexpression of PR3 on the cell surface of neutrophils in WG, ANCA-associated vasculitis and during infection (sepsis). Thus PR3 becomes accessible to ANCA. Furthermore we detected intracytoplasmic IgG antibodies in PMN from patients with WG by immunoelectron microscopy and direct immunofluorescence. Our findings support the pathophysiological role of ANCA.

Fifty-five serum samples from patients with reactive arthritis (ReA), 40 from patients with
ankylosing spondylitis
(AS) and three from patients with chronic sacroiliac joint arthritis were analysed for the presence of ANCA of IgG class by means of enzyme immunosorbent assay using lactoferrin (Lf),
myeloperoxidase
(
MPO
) and antigen extracted from azurophil granules ('alpha-antigen') containing proteinase 3 (PR3) as substrate. IgG-ANCA were found in 31 (56%) patients with ReA. Twenty-three (42%) had anti-Lf antibodies, nine (16%) had anti-
MPO
and eight (15%) had anti-alpha-antigen antibodies, none of which reacted with PR3. Only six (14%) AS or sacroiliac joint arthritis patients had ANCA (P < 0.001). Three (7%) had anti-Lf, two (5%) anti-
MPO
and two (5%) anti-alpha-antigen antibodies. Yersinia and Salmonella bacteria were separated by SDS-PAGE and blots were incubated with serum from rabbits immunized with human Lf. The hyperimmune serum recognized a band of 78 kD from both bacteria which was not seen when preimmune serum was used. The reaction to the 78-kD antigen could be completely inhibited when anti-Lf antibodies were absorbed on Lf coupled to cyanogen bromide-activated Sepharose, possibly indicating cross-reacting epitopes in Lf and enterobacterial antigen.
