The authors sought serum antinuclear antibodies by the indirect immunofluorescent method in 3,260 patients, and found these antibodies in 293 of them. 90 patients had a level equal or greater than 1/50. Among the latter, 54 had some form of collagen disease. The following facts are emphasized: -- antinuclear antibodies are always present in lupus erythematosus. Their levels fall under the influence of treatment when nephritis occurs; -- their frequency is greater (13 cases out of 16) during scleroderma, with often a hazy appearance; -- they are lower during rheumatoid arthritis (23% of cases had a significant level), and their presence is not a sign of worse prognosis; -- they were absent in other forms of collagen diseases.

The detection of anti-DNA antibodies was carried out by the electroimmunodiffusion method. The results were compared to those of the immunofluorescent method for anti-nuclear factors. Positive results were obtained with the electroimmunodiffusion method in 86% of the lupus erythematosus cases, 77% of the sero-positive rhumatoid polyarthritis cases and 67% of the scleroderma cases. They are comparable to those obtained by other methods. The electroimmunodiffusion method allowed in 3 out of 54 sera to defect anti-DNA antibodies although no anti-nuclear factor was found.

The authors review the problem of infection occurring in patients with chronic inflammatory rheumatism, e.g. rheumatoid arthritis, and lupus erythematosus, treated with cytolytic drugs for immunodepressive reasons. From their investigation, it seems that there is a high frequency of bacterial and mycotic and viral infections in these patients, but controlled investigations seem to show quite definitely that the frequency of these infections depends on the disease itself. The risk does not seem to be increased by cytolytic drugs. The only exception is herpes which appears in 10 to 20% of patients treated with immunosuppressive agents, as against 2% in a controll series. The other virus diseases did not have an abnormally high frequency. The conclusions are, of course, only of value for the types of treatment used in rheumatology.

The authors report the case of a young 17 year-old girl with acute systemic lupus erythematosus who presented with purulent arthritis due to Group A hemolytic streptococcus in the knee, and perhaps other joints. She had not yet received any treatment. The purulent arthritis was cured by antibiotics. In spite of corticosteroids and immuno-suppressive agents (Chlorambucil), the patient died one year later. Spontaneous purulent arthritis is rare during systemic lupus erythematosus. We found only 8 other cases in the world literature. Contrary to our case, these were patients already treated with corticosteroid or immuno-suppressive agents. In our patient, the absence of previous treatment permitted us to incriminate the lupus itself in the onset of this infection. The conditions of onset of infection during lupus erythematosus are discussed.

It is important to study coagulation during lupus disease, not only to detect circulating anticoagulants, which may be the cause of hemorrhage, but also in order to seek chronic hypercoagulability, which is more dangerous as it may favour the development of thrombosis on inflammatory arteritis or aggravate the development of glomerular lesions. We have thus explored in this way 25 patients with systemic lupus of which 17 had histologically confirmed renal disease. 25% had hypocoagulability, but 50% had hypercoagulability which justitied treatment with heparin.

Two cases are reported of popliteal cysts simulating sural phlebitis, one in a patient with lupus, the other during the course of rheumatoid arthritis. Diagnosis is based upon the following signs: sudden onset of pain, sometimes after effort, and in the knee rather than in the calf, and more especially ecchymosis occurring in the internal supramalleolar region. The decision as to whether anticoagulant treatment should be instituted must be based on the certitude of the diagnosis, and this can be obtained in an atraumatic manner by ultrasonography of the popliteal fossa as shown by iconography.

Inflammatory rhumatisms simulating rheumatoid arthritis belong to the manifestations of the reactions of leprosy. Pathology of these arthritis variate with the type of reaction. In the present observations, it must probably be the transition from a tuberculoid leprosy to a lepromatosis form in which the immunological state looks like the lupus one.

Previous investigators have reported the presence of complement activation products in scleroderma. Using an assay consisting of isoelectric focussing followed by immunofixation (IEF/IF) for alternative pathway activation product Ba, and an ELISA for C3d that we developed for evaluating lupus plasmas, we assayed 48 plasmas from patients with diffuse cutaneous scleroderma, 16 patients with the limited CREST variant, 2 patients with mixed connective tissue disease (MCTD) and 4 patients with Raynaud's disease. Ba was not detected in any patient's plasma. Only one plasma from a patient with CREST contained elevated levels of C3d. We cannot reconcile the absence of B activation products in our patients with scleroderma with the results of the previous report, and conclude that further studies are necessary.

We present the results of a study of the physical, haematological and serological features of the progress of the SLE-like syndrome in MRL/Mp-lpr/lpr and (NZB x NZW)Fl mice. As part of this study, we have analysed the IEF spectrotypes of anti-ssDNA antibodies in the sera of these mice and shown that the anti-ssDNA response is clonally restricted, as we have previously shown in a mouse chimaera model and in human SLE. Sequential qualitative and quantitative analysis of anti-ssDNA clonotypes has revealed that the lupus mouse anti-ssDNA clones are relatively short lived, having a lifespan of only 6 to 8 weeks, contrasting sharply with the much longer lifespan previously reported for a mouse anti-DNP-secreting clone and the exceptionally long lifespan of most anti-ssDNA-secreting clones of SLE patients. The implications of these observations for our understanding of the regulation of the autoimmune response are discussed.

IEF, using 6 M urea, provides a unique opportunity to analyze the spectrotypes of antibodies in immune complexes (IC) in vivo. Using this technique, we have analyzed the clonotypes of anti-DNA antibodies expressing specific Id in the circulating IC of patients with active lupus nephritis. Serum anti-ssDNA and anti-dsDNA antibodies showed heterogeneous spectrotypes. The antibodies isolated from circulating IC had a restricted clonotype and a neutral charge and were directed mainly to ssDNA and, to a lesser extent, to dsDNA. These samples failed to form complexes with DNA when they were subjected to absorption to a DNA-coupled Sepharose column. Anti-DNA antibodies expressed specific Id, termed O-81 or NE-1, which were detected only in the IC of patients with active lupus nephritis. Anti-DNA clonotypes, including O-81 and NE-1 idiotypes, were also found in the eluates of renal glomeruli of lupus patients. These results indicate that subpopulations of anti-DNA antibodies in circulating IC are limited, and may play an important role in the pathogenesis of lupus nephritis.
