Abstract
FUNDAMENTOS: As manifestações mucocutâneas são comuns em pacientes com lúpus eritematoso sistêmico,podendo assumir espectro bastante variado. OBJETIVOS: Estudar a prevalência de lesões mucocutâneas no lúpus eritematoso sistêmico e verificar suas possíveis associações com auto-anticorpos. MÉTODOS: Submeteram-se 113 pacientes com lúpus eritematoso sistêmico a anamnese dirigida para envolvimento mucocutâneo e exame ectoscópico. Seus prontuários foram examinados para dados demográficos e perfil de auto-anticorpos como anti-Ro/SS-A, antiLa/SS-B, antiDNA e anti-Sm. RESULTADOS: Os achados mais prevalentes foram os de fotossensibilidade (83,1%), alopecia (65,4%), eritema em vespertílio(54,3%) e fenômeno de Raynaud (53,9%). Em 46,9% existia algum tipo de queixa mucocutânea no momento do diagnóstico da doença. Encontrou-se associação entre a ocorrência de lúpus cutâneo subagudo e presença do anti-Ro/SSA (p = 0,03), do fenômeno de Raynaud e o anticorpo anti-Sm (p = 0,05) e do eritema em vespertílio e o anticorpo antiDNA (p = 0,03). CONCLUSÃO: Os achados mucocutâneos estão presentes na maioria dos pacientes com lúpus sistêmico, existindo em aproximadamente metade deles no momento do diagnóstico. As lesões mais comuns foram fotossensibilidade, alopecia, eritema em vespertílio e fenômeno de Raynaud.
BACKGROUND: Mucocutaneous manifestations are very common in systemic lupus erythematosus and vary widely. OBJECTIVES: To study the prevalence of mucocutaneous lesions in systemic lupus erythematosus and to verify their possible association with autoantibodies. METHODS: One hundred and thirteen patients with systemic lupus erythematosus underwent clinical history directed to skin disorders and ectoscopic examination. Their charts were reviewed for demographic data and autoantibody profile (anti-Ro/SS-A, anti-La/SS-B, anti-DNA and anti-Sm). RESULTS: The most prevalent findings were photosensitivity (83.1%), alopecia (65.4%), butterfly rash (54.3%) and Raynaud’s phenomenon (53.9%). In 46.9% of patients there was mucocutaneous complaint upon diagnosis. We found an association between subacute cutaneous lupus and anti-Ro/SS-A (p=0.03), Raynaud’s phenomenon and anti-Sm(p=0.05), butterfly rash and anti-DNA (p=0.03). CONCLUSION: Mucocutaneous lesions are present in most systemic lupus patients and in almost half of them they are present at diagnosis. The most common findings were photosensitivity, alopecia, butterfly rash and Raynaud’s phenomenon.
