[Disseminated lupus erythematosus in children: guidelines about investigations during the initial evaluation and follow-up].

Childhood-onset systemic lupus erythematosus (SLE) is often severe and has a serious long-term morbidity. Pediatric guidelines about its management do not exist. The French study group of childhood-onset SLE proposes recommendations about the investigation which are needed at diagnosis and during follow-up of SLE, in order to adjust the treatment according to the severity of the disease and to avoid unnecessary investigations.

[Association of disseminated lupus erythematosus and Crohn's disease].

INTRODUCTION: Association of Crohn's disease and systemic lupus erythematosus is infrequent. We report an observation of Crohn's disease that appeared in an 18-year-old woman followed-up for systemic lupus erythematosus for four years. EXEGESIS: The patient had all the clinical, biological and histological criteria of Crohn's disease and systemic lupus erythematosus was diagnosed according to the American Rheumatism Association criteria. On the base of this observation, we discuss the digestive manifestation of systemic lupus erythematosus and extradigestive manifestations of Crohn's disease. CONCLUSION: The immunological background of both diseases was proposed to explain the mechanism of this rare association.

[Thymoma and disseminated lupus erythematosus. Two new cases and review of the literature].

INTRODUCTION: Thymoma is a tumour originating in the epithelial cells of the thymus, associated with several immunologic disorders. The association of thymoma with systemic lupus erythematosus has rarely been described. We report two cases of this association. EXEGESIS: Description of two cases and a review of the literature. Mr T. was 41 years old when the diagnosis of thymoma and lupus was made. The thymectomy did not influence the evolution of his lupus. Mrs G. had been treated because of a lupus for 8 years prior to developing a thymoma. One year later she presented with erythroblastopenia, which was only sensitive to cyclosporin. CONCLUSION: The association between lupus and thymoma has been reported in 36 cases in the literature. Thymoma is benign in 59% of the cases. The clinical presentation of lupus is nonspecific except for age, median 48 years, and sex ratio, 4:3. The clinical outcome of the lupus is not influenced by the thymectomy. Thymoma may precede lupus with a delay of several years or it may be diagnosed concurrently or several years later. This association is not accidental, though the pathogenic link between these conditions remains unknown. One could suppose that the decrease of the thymic function in the course of thymoma could enhance the expression of autoreactive T lymphocytes as well as the activation of B cells. Patients should be followed after thymectomy because autoimmune diseases, particularly lupus, may develop belatedly. On the other hand, thymoma may be suspected mainly when lupus occurs in patients around 50 years of age.

[A case of post-partum remission of acquired dyserythropoiesis, a rare cause of anemia in disseminated lupus erythematosus].

INTRODUCTION: Amongst the various causes of anemia in systemic lupus erythematosus, isolated and acquired erythrocyte dysplasia is rare and most often part of global dysmyelopoiesis. EXEGESIS: The authors report a case of acquired erythrocyte dysplastic syndrome that occurred in a 34-year-old woman in whom previous diagnosis had evidenced systemic lupus erythematosus of rather benign course. Other causes of dysmyelopoiesis were ruled out. Myeloid stem cell cultures showed selective inhibition of erythroid cells growing, with no particular effect of the patient's serum. While a corticosteroid treatment with prednisone (1 mg/kg/d) did not show any efficacy upon anemia, the patient's pregnancy was followed by prolonged correction of hemoglobin, making possible the tapering of prednisone down to 10 mg/d. CONCLUSION: Acquired erythrocyte dysplastic syndrome remains a rare cause of anemia in systemic lupus erythematosus. This case report suggests an immunological phenomenon, but the mechanisms underlying both the appearance and long-lasting remission after pregnancy remain unexplained.
