Lupus eritematoso sistémico en el anciano: una presentación atípica de una enfermedad común / Systemic lupus erythematosus in the elderly: An atypical presentation of a common disease

El lupus eritematoso sistémico (LES) del anciano, también llamado lupus de aparición tardía,es una enfermedad autoinmune que aparece después de los 50-60 años, con un curso clínicoy manifestaciones clínicas que difieren del LES clásico, cuya prevalencia es en personas másjóvenes, predominantemente mujeres. Se presenta, en este artículo, el caso de un pacientemasculino de 72 años con cuadro clínico de un mes de evolución de dolor en hemitóraxderecho, tipo pleurítico asociado a disnea, además de la presencia de lesiones eritematosasy descamativas en región malar y zona de exposición solar en tórax. Se descartó origeninfeccioso y neoplásico mediante imágenes diagnósticas y laboratorios y, posteriormente,se realiza perfil inmunológico que reporta ANAS positivo, Anti-DNA positivo y complementoconsumido, con evidencia de derrame pleural derecho masivo recidivante hasta la fecha.

Systemic lupus erythematosus (SLE) in the elderly, also called late-onset lupus, is an autoimmune disease that appears after 50-60 years old, with a clinical course and clinical manifestations that differ from classic SLE, with a prevalence predominantly in younger women. In this article a case of a 72 year-old male patient who, for one month, had clinical symptoms of right chest pain, associated with dyspnea and the presence of erythematous and scaly lesions on the malar area and sun exposure in the thorax. The possibilities of infectious or neoplastic origin were dismissed using diagnostic images and laboratory tests. An immunological profile was subsequently performed, reporting positive ANAS and Anti-DNA, positive, and consumed complement, with evidence of recurrent massive right pleural effusion to date.

Clinical and immunological features of 888 Brazilian systemic lupus patients from a monocentric cohort: comparison with other populations.

Epidemiological studies with systemic lupus erythematosus (SLE) patients have been reported worldwide but, until now, a large evaluation had not been performed in Brazil. Therefore, we determined the clinical and immunological features of 888 SLE patients followed at our service from 2008 to 2012. The mean age at SLE onset and the mean disease duration were 29.9 ± 9.5 years old and 14.5 ± 8.4 years, respectively. A predominance of female gender (91.9%) and Caucasian ethnicity (69.9%) were observed. Cumulative mucocutaneous manifestations (90.7%) were most commonly identified (malar rash (83.2%), photosensitivity (76.9%)) followed by articular (87.4%), hematological (44.0%) and renal (36.9%) involvements. Antinuclear antibody was detected in all patients, followed by anti-dsDNA (35.1%), anti-Sm (21.8%) and anti-ribosomal P protein antibodies (19.8%). Additional comparison of clinical and laboratory features between genders revealed that malar rash was observed more in female SLE patients (84.5% vs. 69.4%, p = 0.001). Male lupus patients presented a higher frequency of anti-dsDNA (45.8% vs. 34.2%, p = 0.047) and a trend of more nephritis (47.2% vs. 36.0%, p = 0.059). In conclusion, we identified a high prevalence of mucocutaneous manifestations in this Brazilian SLE cohort compared to other countries, mainly malar rash that was most commonly observed in female patients. Anti-dsDNA and other specific SLE autoantibodies were also identified in a higher frequency, predominantly in the male gender.
