[Interleukin 2 and rheumatoid polyarthritis].
The dysimmune state associated with rheumatoid arthritis was approached by the study of a T lymphocyte function, the production of helper factor: Interleukin 2 (I12). This production was measured in 11 patients in comparison with 9 controls. The I12 activity is significantly higher in the patient group. Several mechanisms may be involved in this over-production. The radiosensitive T suppressor function, which was also investigated in this study, was the same in the two groups, so can not explain this overproduction. However, the radiosensitive suppressor function is very variable in the patients, suggesting a clinical correlation which could not be confirmed in this small group of subjects.
[Long-term study of 150 mg. Bi-Profenid in patients followed at the Department of Rheumatology of Cochin Hospital].
The effectiveness and tolerance of Bi-Profenid 150 mg (two tablets a day) was evaluated in 37 patients under long-term treatment by retrospective analysis of case records. Mean duration of therapy was 15.5 months. Over this period improvement in the usual surveillance criteria was recorded. In 6 patients the "therapeutic follow-up test" allowed to decrease dosage to one tablet a day. Conversely, attempts at discontinuing the drug were followed by recurrence of pain. Tolerance was evaluated as excellent in 89% of cases and the only recorded side-effects were gastrointestinal.

[Plasma androgens in women with disseminated lupus erythematosus].
Plasma androgen levels were determined by radio-immunoassay in 19 female patients (aged 14 to 42 years) with systemic lupus erythematosus (SLE). In 11 patients studied in the active phase of the disease, prior to any corticosteroid therapy, mean (+/- SEM) plasma concentrations (ng/ml) of the following androgens were significantly reduced as compared with controls (12 normal women aged 19-37 years): testosterone (0.119 +/- 0.021 vs 0.330 +/- 0.034, p less than 0.001), dihydrotestosterone (0.078 +/- 0.013 vs 0.150 +/- 0.014, p less than 0.01), dehydroepiandrosterone (1.60 +/- 0.16 vs 4.30 +/- 0.50, p less than 0.001), dehydroepiandrosterone sulfate (480 +/- 102 vs 1020 +/- 92, p less than 0.001), and androstenedione (0.69 +/- 0.22 vs 1.45 +/- 0.18, p less than 0.02). In 8 patients studied while in post-therapeutic remission, six months to seven years after corticosteroid withdrawal, plasma concentrations of the same androgens (except androstenedione) were also significantly reduced as compared with controls, although to a lesser degree. In neither of the two patient groups were cortisol and estradiol levels significantly different from controls. Our results suggest that low plasma androgen levels could be a permanent disorder in female SLE patients, at least in severe forms of the disease.
[Problems posed by pregnancy in women with lupus nephropathy].
The influence of lupus nephropathy on pregnancy and reciprocally was retrospectively studied in a series of 131 pregnancies observed from 1962 to 1981 in 45 systemic lupus erythematosis (SLE) women with renal involvement. Renal biopsy showed proliferative lupus glomerulonephritis in 27. The incidence of live births, corrected for induced abortions, was 87% in 89 pregnancies started before, and 89% in 32 started after the clinical onset of SLE; it was only 63% in 10 cases where lupus nephritis developed during gestation. Relapse or exacerbation of disease activity occurred in 15 (47%) of 32 pregnancies antedated by the onset of SLE, with irreversible renal failure in two cases. Clinical exacerbation of SLE was observed in 13 (76%) of 17 cases where SLE was clinically active at the time of conception, and in only 2 of 15 cases where lupus nephritis was in stable clinical remission for at least 5 months prior to conception. Our data suggest that a successful outcome of pregnancy, without SLE exacerbation, may be expected, even in the more severe forms of lupus nephritis, when gestation begins after a sustained, complete clinical remission.

[Eosinophilic arthritis and general review of the significance of articular eosinophilia].
The authors report two cases of eosinophilic arthritis in allergic patients, which constitute the 9th and 10th reported cases. This condition consists of episodes of mildly painful, mildly incapacitating monoarthritis, essentially involving the knee, which last 2 to 15 days. These monoarthritis occur in young allergic patients; there are no allergic manifestations during the episode of arthritis and there is apparently no provoking allergen, but examination reveals intense dermographism. Apart from the presence of eosinophil polymorphonuclear cells in the synovial fluid, one can also find Charcot-Leyden crystals (one of the two cases in this study). The histological examination of the synovial membrane in one of these patients revealed an infiltration of eosinophil polymorphs. A raised serum IgE is always found. Including these two cases, the authors have found 11 out of 4277 specimens of joint fluid which show articular eosinophilia. The nine other cases consisted of one haemarthrosis, two post-arthrographic effusions, one filarial arthritis, one psoriatic rheumatism, one Gougerot-Sjögren syndrome and three cases of unclassifiable arthritis. Data from the literature show that articular eosinophilia is a rare phenomenon, that it does not constitute a simple local reflection of a blood hypereosinophilia and that it can consist of the cases found in this study.
[Lymphocytic arthritis. 54 cases, of which 25 appear to be idiopathic].
The authors studied rheumatological disorders possibly accounting for significant articular lymphocytosis (greater than or equal to 90 percent). A precise diagnosis was established in 29 of 54 cases: haemophilic arthritis (3 cases), villonodular synovitis (3 cases), tubercular arthritis (1 case), rubella (1 cases), aseptic arthritis of Osler's endocarditis (2 cases), necrosis of the inner condyl (1 case), Gougerot-Sjögren syndrome (1 case), classical rheumatoid polyarthritis (8 cases), probable (7 cases). The other 25 patients suffered from: polyarthritis (7 cases), oligoarthritis (1 case), biarthritis (8 cases) and monoarthritis (9 cases) of undetermined etiology. Besides articular lymphocytosis, clinical radiological and histological study of these patients indicates that this is a distinct rheumatological entity.

[Effect of hormonal contraception on the course of lupus nephropathy].
Influence of oral contraceptive therapy on SLE activity was evaluated in 33 female patients with lupus nephropathy. Estroprogestative preparations containing either 50 micrograms (18 cases) or 30 micrograms (11 cases) of ethinylestradiol were used in 29 courses in 28 patients. Onset or exacerbation of clinical SLE activity occurred within 3 months after starting hormonal therapy in 13 cases, an overall incidence of lupus flare-up of 44 percent, involving major renal histological lesions in 5 cases. In contrast, of 16 patients receiving pure progestogen contraceptive therapy with either discontinuous normal dosage progestogens (9 cases) or continuous low-dose norsteroids (7 cases), only one developed clinical or immunological evidence of lupus exacerbation within 3 months of hormonal therapy. We conclude that oral contraceptive therapy using estrogens, even at low dosage, is associated with a high risk of SLE exacerbation. Pure progestogens, which have proven effective and devoid of such unfavorable effects, should be preferred in these patients when hormonal contraception is needed.

Lupus nephropathy and pregnancy. Report of 104 cases in 36 patients.
The reciprocal influence of lupus nephropathy on the outcome of pregnancy and of pregnancy on the course of renal involvement was studied retrospectively in a series of 106 pregnancies observed during the past two decades in 36 patients with lupus nephropathy. The overall incidence of live births, corrected for induced abortions, was 54 (84%) in 64 pregnancies that began before clinical onset of systemic lupus erythematosus (SLE), 20 (87%) in 23 pregnancies that began after onset of SLE, and only four (57%) in seven cases where SLE was first manifested during or after gestation. Relapse or exacerbation of disease activity occurred in 12 (46%) of 26 pregnancies antedated by clinical onset of SLE, more frequently during gestation than post partum, with two cases (8%) of irreversible deterioration of renal function; clinical exacerbation of lupus disease was observed in 11 (66%) of 15 cases where SLE was clinically active at the time of conception, and in only one (9%) of 11 cases where SLE nephritis was in stable clinical remission for at least five months before conception. The data indicate that successful outcome of pregnancy may be expected even in the more severe forms of lupus nephritis if gestation begins after a sustained, complete clinical remission.
