Análise de prevalência e evolução das manifestações neuropsiquiátricas moderadas e graves em pacientes com Lúpus eritematoso sistêmico internados no Serviço de Reumatologia do Hospital Geral de Fortaleza

Abstract

Objective: Evaluate the prevalence and therapy outcome of moderate and severe neuropsychiatric manifestations (NPM) in patients with systemic lupus erythematosus admitted at the Hospital Geral de Fortaleza. Methods: During two years, 110 patients with consecutive hospitalizations suffering from systemic lupus erythematosus, according to the American College of Rheumatology criteria, were evaluated for moderate and severe NPM. The following parameters were studied in these patients: cause of admission, presence of auto-antibodies, cerebral spinal fluid, radiological imaging, retrospective study of medical records and treatment. Results: The prevalence of NPM was 16.4% (18/110), being seventeen women and one man; the mean age was 29 years; during the hospitalization term, only 33% (6/18) of the patients had an NPM. The occurrence of the first NPM was in 11% (2/18) of the cases before diagnosis, in 33% (6/18) during diagnosis and in 56% (10/18) after diagnosis. The mortality rate was 11% (2/18). The most common NPM's were: seizures and headache (50%), psychosis (22%), cerebrovascular disease (17%), syncope and major depression (11%). Treatment outcome: 28% (5/18) of the patients responded to oral corticoids, 17% (3/18) had a pulse of methylprednisolone and 56% (10/18) were treated with cyclophosphamide. Conclusion: The prevalence of NPM in the patients of this study was on the lowest limit reported by the related literature. With no controlled clinical trials, the approach to these patients is based on case reports and the professional experience of the service.
