The prevalence of anti-endothelial cell antibodies (AECA) of IgA, IgG and IgM classes was studied by means of enzyme-linked immunosorbent assays (ELISA) in 466 patients with autoimmune/inflammatory disorders. The reference limits in the ELISAs for the AECA were determined from a random population sample of 249 subjects. The frequency of AECA was highest in patients with SLE (n = 42), 14.6% mainly of IgG class, and the presence of AECA correlated with disease activity in these patients. In the RA patient group (n = 200), 9.5% had AECA, mostly of IgA type. We found no association between the presence of AECA and extra-articular manifestations of RA or survival rate. In patients with undefined connective tissue disease (n = 57), ankylosing spondylitis (n = 109), and psoriatic arthritis (n = 58), the frequency of AECA corresponded to that of the random population sample. In a cohort of samples sent to the laboratory for determination of anti-nuclear antibodies (ANA) there was a correlation between the presence of ANA and AECA. Our findings indicate that RA patients are characterized by IgA class AECA, whereas SLE patients have IgG class AECA also correlating to disease activity.

Ninety four Finnish conscripts were affected by a Yersinia enterocolitica epidemic in 1973. Thirteen years later 75 men completed a questionnaire about their present health. One half had no health problems, and the most common complaints in the other subjects were musculoskeletal disorders. Sixteen men wanted to be re-examined. In three cases a chronic connective tissue disease was diagnosed. Two men had ankylosing spondylitis. The most notable results of this study were (a) the fairly low number of late complications, (b) the close correlation between complications and the HLA-B27 antigen, and (c) the correlation between raised yersinia antibody titres and the late complications. The nature of the primary causative agent may affect the development of late complications.

In this study is presented the experience of 294 patients with different connective tissue diseases such as: a) rheumatoid arthritis, b) systemic lupus erythematosus, c) ankylosing spondylitis, d) progressive systemic sclerosis, e) dermatomyositis-polymyositis and f) mixed connective tissue disease. All these patients were studied prospectively during the last eight years through non-invasive methods to detect cardiovascular complications. The connective tissue diseases can provoke inflammation and fibrosis in any of the diverse cardiac structures, with the consequent complications. These alterations are frequent, with a high degree of morbidity, and have a direct relationship with the severity and chronicity of the primary connective tissue disease. Some of these patients respond favorably to cardiological and anti-inflammatory management, while others are refractory to such treatments. The prognosis of the observed complications in these patients depends in great part on the development of the basic rheumatic disease. This kind of patients should be studied systematically from the cardiological view point, so as to detect these complications as early as possible.

Serum IgG antibodies to native and denatured human type II collagen (Col II) were measured using an enzyme linked immunosorbent assay (ELISA). One hundred and thirty one patients with various forms of arthritis such as rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PSA). Reiter's Syndrome (RS), osteoarthritis (OA), and gout, 60 with autoimmune connective tissue disease, and 37 with the chronic inflammatory conditions--graft versus host disease and leprosy--were studied. With the exception of RS, PSA, OA, and gout, significant levels of Col II antibodies were detected in each disease group. Blocking studies with types I and II collagen on selected serum samples confirmed the specificity to native Col II, though some cross reactivity was apparent with denatured collagen. The patients with RA who were Col II antibody positive tended to fall into stage III of disease progression. There was, however, no correlation with rheumatoid factor, erythrocyte sedimentation rate, or disease duration and this, together with the finding that Col II antibodies are present in a wide array of diseases, makes their role in the pathogenesis of RA questionable. They may arise as a secondary disease perpetuating mechanism in some patients, or in turn may be an epiphenomenon secondary to generalised disturbed immunoregulation or B cell hyperreactivity, or both, that characterises these clinical conditions.

Among 173 consecutive open lung biopsies, nine gave a histopathological diagnosis of bronchiolitis. Seven of these patients had some connective tissue disorder (CTD), six of whom are presented in this report; two had classical and one possible rheumatoid arthritis (RA), one ankylosing spondylitis, one scleroderma, and one developed classical RA four years after biopsy. Four of the patients were smokers, most suffered from breathlessness and cough. In terms of lung function three patients had obstruction, one both restriction and obstruction and three a decreased diffusion capacity. For control purposes peripheral lung tissue was studied histologically from 24 consecutive smoking patients without CTD who underwent a lobectomy for cancer. Intraluminal plugs and mucosal lymphoplasmocytic infiltration of the bronchiolar walls were more prevalent and abundant in the CTD patients than in the controls (p less than 0.02 and p less than 0.001 respectively). Two CTD patients also showed some obliterative bronchiolitis. Corticosteroids were effective in one out of four patients treated. One patient improved and the others did not show any progression during the follow up. The results suggest that smoking alone does not explain the lesions of the small airways found in CTD patients, and that bronchiolitis may be specifically associated with the basic disorder in such cases.

The prognosis 3 years after the onset of the disease was studied in 107 patients with definite rheumatoid arthritis, 161 with probable RA or non-specific arthritis, 84 with either ankylosing spondylitis, Reiter's disease or reactive arthritis, 14 with psoriatic arthritis and 10 with a systemic connective tissue disease. Prognosis was measured by clinical involvement of joints, radiological erosions in joints, deterioration in joint function, ESR, and working ability. A total of 44% of all patients were symptomless after 3 years. The prognosis was best in patients with an "HLA B 27-associated" disease and non-specific arthritis, and worst in RA. Two patients died during the follow-up of systemic connective tissue disease and one committed suicide with an overdose of hydroxychloroquine. Two HLA B27-positive patients developed systemic amyloidosis.

Fibrodysplasia ossificans progressiva (FOP) is a rare hereditary connective tissue disorder. Patients with FOP develop progressive ossification of muscle and connective tissue associated with pain and disability. Onset is typically in childhood, and congenital anomalies of the feet are an early sign of this condition. Pain and stiffness of the spine or an inflammatory mass are common presenting features of FOP. Involvement of the spine often leads to complete fusion mimicking ankylosing spondylitis. Studies of twins and families suggest that FOP is a genetically inherited autosomal dominant trait with complete penetrance but variable expressivity. While radionuclide imaging and computed tomography are very sensitive for new bone formation and greatly assist the diagnosis of FOP, unfortunately, effective therapy is unavailable. We present twins with FOP and review the clinical, radiographic, and genetic manifestations of this disorder.

Juvenile chronic arthritis (JCA) is the most common connective tissue disease affecting the articular structures in children. This paper examines radiographic findings in the foot and ankle of patients with JCA. In addition, the importance of foot and ankle radiographs in distinguishing juvenile-onset ankylosing spondylitis from two other subclasses of JCA are discussed.

We report the case of a 45-year-old Caucasian woman suffering from ankylosing spondylitis and undifferentiated connective tissue disease in whom the prevailing clinical features were retinal vasculitis and inflammatory low back pain. HLA typing revealed the concomitant presence of B27 and DR2 antigens. We hypothesise that the uncommon coexistence of ankylosing spondylitis and connective tissue disease in the same patient could be due to the exceptional association of HLA- B27 with the DR2 antigen.

The possible role of infectious microorganisms in the disease process of both arthritis and autoimmunity continue to attract both basic and clinical researchers. However, proving a causal role for these suspects is a very difficult and complicated task. This article provides an update on various mechanisms in which microbes may play roles as inciting or perpetuating factors in the pathogenesis of connective tissue disease. It also focuses on current theories that specific microorganisms may play a role in rheumatoid arthritis and ankylosing spondylitis.
