ABSTRACT

Introdução: Nefrite é uma manifestação freqüente no lúpus eritematoso sistêmico (LES), tendo uma prevalência de 40 a 75%. Embora esteja associada com a ocorrência de anticorpo anti-DNA, outros autoanticorpos podem estar ligados ao seu aparecimento taiscomo o fator reumatóide (FR) e os anticorpos antifospholípides (aPl).Objetivos: verificar a prevalência de nefrite lúpica local e sua associação com o a presença do FR e aPls. Métodos: Revisaram-se 187 prontuários depacientes com LES para presença de nefrite, FR e aPl . Resultados: Encontrou-se uma prevalência de 35,3% de glomerulonefrite. Houve correlação negativa entre nefrite e FR (p=0.001). Não se encontrou associação entre aparecimento de aPl e nefrite, já queo número de pacientes com glomerulonefrite que apresentaram esses testes positivos foram de 8 (32%)em 59; 5 (27,7%) em 58 e 6 (46,1%) em 29, respectivamente. Conclusão: Existe uma prevalência de 35% denefrite na população local de LES a qual tem uma associação negativa com aparecimento do FR. Presença de aPls não influíram no aparecimento da nefrite lúpica.


Summary: Nephritis is a frequent manifestation of systemic lupus erythematosus (SLE), with an averageof 40 to 75%. It’s associated with the presence of anti-DNA antibodies;other antibodies may also be involved,such as rheumatoid factor (RF), and antiphospholipid antibodies (aPl).Objectives: to verify the prevalence of lupus nephritis and its association with RF and aPl antibodies. Methods: The charts of 187 patients with SLE werereviewed for the presence of nephritis, RF and aPl. Results: A prevalence of 35.3% of nephritis was found. There was a negative correlation betweennephritis and presence of rheumatoid factor (p=0,001). No association between the presence of aPl and nephritis was found, since the number of patients with glomerulonephritis that were positive for these tests wasof 8 (32%) in 59, 5 (27,77%) in 58 and 6 (46,1%) in 29, respectively.Conclusion: There is a prevalence ofglomerulonephritis of 35% in the local SLE population, which has a negative association with rheumatoid factorpresence. Antiphospholipid antibodies aren’t associated to the occurrence of lupus nephritis.
