Seventeen cases of Wegener's granulomatosis have been reviewed in search of articular involvement. Articular symptoms were present in 13 cases (76 p. cent), and were inaugural in 9 cases (53 p. cent). Six of these patients experienced arthralgias, which were most often migratory, and were inaugural in 3 cases. Seven patients had arthritides, which were inaugural in 6 cases; they were fixed and additive in 6 of these 7 cases, making up a distal polyarthritis in 3 patients, and an oligoarthritis in the 3 other ones; they were transient and migratory in 1 case. The 3 cases of distal polyarthritis were inaugural and fulfilled the ARA criteria for rheumatoid arthritis; two of them were accompanied by nodules which were quite identical to rheumatoid ones. There was no axial involvement. Joint involvement was not destructive and had a favourable course under disease treatment. Myalgias were present in 3 cases, one of which simulated Horton's disease. Biological manifestations chiefly consisted of marked inflammatory changes. Antineutrophil cytoplasm antibodies were present in 11 out of 16 patients in whom they were searched; among 6 of these patients who had active disease, they were present in 5. The antibody level decreased as treatment reduced disease activity and suppressed joint involvement. Joint involvement in Wegener's granulomatosis seems to be the inconstant hallmark of disease activity. It requires no specific treatment.

Three aspects of the action of oxygenated free radicals were studied in 10 controls and 20 patients with rheumatoid arthritis, 11 not treated and 9 treated with D-penicillamine. Free radical production was evaluated in whole blood, malondialdehyde was measured in plasma, the concentration of antiradicular enzymes (copper and manganese superoxide dismutase, catalase and glutathion peroxydase) in hemolysate, platelets and plasma and copper superoxide dismutase activity in a chloroform erythrocyte extract. Only patients treated with D-penicillamine showed a significant decrease in the concentration of platelet anti-radicular enzymes and plasma manganese superoxide dismutase. The involvement of oxygenated free radicals in the pathophysiology of rheumatoid arthritis and in the mechanism of action of D-penicillamine in this pathology is discussed.

Cytokines play a role in the chronicity of inflammation, the formation of lesions and the persistence of the immune response observed in rheumatoid arthritis (RA). The dysregulation of the cytokines observed in RA is of great immunopathological importance. There is an increase in the macrophage-derived cytokines such as interleukin 1, the tumor necrosis factor alpha and interleukin 6. At the same time, there is a decrease in the lymphocyte-derived cytokines such as interleukin 2, interferon gamma and interleukin 4. Certain growth factors (transforming growth factor beta, platelet derived growth factor, granulocyte macrophage-colony stimulating factor) also play a role in RA. The study of the role of these various cytokines in the formation and maintenance of articular and extra-articular lesions in RA is carried out.

While rheumatoid arthritis apparently did not exist in the Old World prior to the eighteenth century, a symmetrical erosive arthritis, indistinguishable from contemporary rheumatoid arthritis is clearly documented in the 1,000 year before present Fort Ancient-Anderson Village site. As lesions compatible with a diagnosis of rheumatoid arthritis have not been noted in the Old World prior to 1785, observation of 35 pre-Columbian cases of compatible lesions, suggests the likelihood that rheumatoid arthritis is a New World disease that subsequently spread to the Old World. Study of the geographical patterns and timing of distribution of rheumatoid arthritis and of New World organic items may provide an opportunity to identify the responsible pathogens or allergens.

In France, about 3,000 children under 16 years of age suffer from juvenile chronic arthritis (JCA), whose management presents a problem. JCA covers several nosological entities. In 20% of the cases, a systemic form affecting the articulations in an inconstant way, and starting in the very young child, is observed. In 30% of the cases, a form with a polyarticular start is observed. This group is very heterogeneous and includes in particular early seropositive rheumatoid arthritis (RA), the little girls' polyarthritis with presence of antinuclear antibodies, and the little boys' rheumatisms HLA B27. Finally, in 50% of the cases, an oligoarticular form is observed, also expressed in greatly varying ways. In all cases, the evolution is unpredictable and the management of these children is different from that of adults. It must be noted that the treatments used in adults are rarely applied to children as JCA is a pathology which is quite different from RA. Several types of treatment can be administered by general route: non-steroidal antiinflammatory drugs (NSAIDs) and mainly aspirin, since few NSAIDs have a paediatric licence in France. However, the risks of intolerance at doses reaching up to 100 mg/kg are not negligible. Some NSAIDs can be used in older children. The slow acting drugs are dangerous in the systemic form of JCA. Their indication seem to be more appropriate in the polyarticular forms. In the oligoarticular forms, slow acting drugs are rarely proposed. Corticosteroids are prescribed in aspirin-resistant systemic forms only. Besides the complications observed in adults, the growth is stopped in a constant way.(ABSTRACT TRUNCATED AT 250 WORDS)

Methotrexate, an antifolate cytotoxic drug, is used in anticancer chemotherapy as well as an immuno suppressive in rheumatoid arthritis. It is responsible for numerous secondary effects, amongst which is a characteristic acute pneumonia known since 1969. This pneumonitis has been described in detail, up to the present time in 78 cases gathered in this review. The prevalence of this complication is estimated at around 7%. This pneumonia may occur whatever the age, indication for which methotrexate is prescribed, the route of administration of the product (including the intra-thecal route) and the dose. It includes dyspnoea, fever, (sometimes quite marked) and frequently an acute reversible respiratory failure. Radiologically the opacities are usually diffuse interstitial and symmetrical with a basal predominance with sometimes some confluence and occasionally a pleural reaction. In a small number of cases a transient mediastinal adenopathy has been described. Respiratory function tests show a rapidly developing restrictive syndrome accompanied by hypoxia and hypocapnia. Broncho-alveolar lavage is characterised by hypercellularity with a frank and apparently transitory lymphocytosis. Histologically the most frequent lesion sighted is an extensive acute granulomatous reaction with or without oedema. Most often the outcome is favourable (75% of cases). However 6 deaths due to respiratory failure have been reported. Even though there has not been any formal test, steroid therapy in high dosage seems to accelerate recovery. Progress to an irreversible pulmonary fibrosis is possible but rare. The mechanism of this drug related acute pneumonia is not known but would seem to resemble that of other granulomatosis. Besides this rapidly progressive pneumonitis, methotrexate is responsible for a very small number of cases of severe pulmonary oedema and of acute painful pleurisies.

The concentrations of sex hormones were studied in 45 women with rheumatoid arthritis (RA). The patients were classified into two groups. Group I (premenopausal) consisted of 26 women and group II (postmenopausal) included 19 women. The two groups were compared with 40 control women (20 premenopausal and 20 postmenopausal). Age and weight were comparable in the 2 groups (controls and patients). The average plasma concentrations of oestradiol, progesterone and androgens were comparable in group I (patients with RA) and the control group (premenopausal women). On the other hand, the plasma concentration of androgens was statistically significantly higher in patients in group II by comparison with the postmenopausal controls. It thus seems that a hyperandrogenic situation may occur in menopausal women with RA, and this might have a beneficial clinical effect on the disease.

This study involved the screening for dermal microcirculatory abnormalities using periungueal capillaroscopy in a group of 80 cases of rheumatoid arthritis, so-defined in terms of ARA criteria. Excessive erythrocyte aggregation and/or pericapillary edema were detected in 74% of cases and were statistically correlated with ESR, reflecting an inflammatory syndrome. Capillary neogenesis, probably in reaction to subclinical cutaneous vascularity, was detected in 59% of cases (86% of subjects presenting extra-articular rheumatism). In 28% of cases this was accompanied by spontaneous hemorrhage, suggesting a progressive condition. Stigmata of cutaneous atrophy were present in 54% of subjects. These findings demonstrate the frequency of subclinical cutaneous damage in rheumatoid disease and suggest the possibility of the clinical usefulness of capillaroscopy, a non-invasive technic, in the follow-up of this disease.

Eight immunological parameters were explored in 257 patients with various rheumatic diseases including 107 rheumatoid arthritis (RA). IgG and IgM antibodies (AB) reactive with the Stratum Corneum (SC) of rat oesophagus or with the SC of human skin were assayed by 1/2 quantitative indirect immunofluorescence, IgG and IgM auto AB to epidermal keratins by a specific ELISA, and total serum G and M immunoglobulins by radial immunodiffusion. At the threshold we chose (99 p. cent specificity), IgG anti SC of rat oesophagus, were found in 50 of 107 (46.7 p. cent) RA patients: 52.5 p. cent in sero + and 39.6 p. cent in sero - ones. The other parameters, separately considered, had no diagnosis value. In Paget disease serum IgM and IgG and all the AB of M isotype were found to be broken down. In all the groups, the isotype AB were found strongly correlated to each other and to serum IgM. The RA sera with specific AB to the rat oesophagus SC, also labeled human skin SC but these labeling were unrelated to the anti-keratins auto AB level. On the contrary, the anti SC AB of G isotype, detectable on human skin in psoriatic rheumatism did not label rat oesophagus. These results confirm the diagnosis value of IgG AB to SC of rat oesophagus, usually called anti-keratins, who appear as a marker for RA. This work shows the relevance of associating specific immunochemical techniques to immunofluorescence, in order to unravel the antigenic complexity of tissular substrata.

Rheumatoid arthritis is a disease determined and influenced by many factors genetic, environmental, endocrine, psychological and immunological. Immunological mechanisms (hyperexpression of class II HLA antigens, cytokinin anomalies, functional deficiencies of certain lymphocyte categories, polyclonal activation of B lymphocytes with production of antibodies) suffice to maintain between them the immune response, synovial inflammation, and lesions of bone and cartilage. Progress in understanding these diverse pathogenic factors in RA will eventually lead more selectively targeted treatments to supercede the present empirical use of basic treatments.
