Abstract
Objective: We assessed the prevalence of erythrocytic changes in patients with SLE, at Cuiabá University General Hospital (UNIC-HGU). Methods: blood samples from 40 female patients were collected and processed (ABX Pentra 80 automation – flow cytometry). Descriptive statistical analyses were performed using IBM SPSS 2.0 statistical software. Results: 42.5% of the 40 patients showed lowered concentrations of hemoglobin. The hematocrit and hemoglobin dosage averages of the anemic patients were respectively of 29.7% and 9.9 gdL, while those without anemia showed 41.1% of hematocrit average and hemoglobin average dosage of 13,7gdL. Normocytic and normochromic anemia was the most prevalent, founded in 64.7% of the anemic patients, with normal hematimetric indices. In cases of macrocytic anemia, hematimetric changes, such as increased RDW, policromasy and reticulocytosis observed in some patients suggest hemolytic processes, commonly observed in these patients. Conclusion: Anemia was found in 42% of the patients and careful observation of the erythrocytic changes is an important tool in the follow up of LES patients

Summary
RESUMO Objetivo: Determinar as alterações eritrocitárias em pacientes com Lupus Eritematoso Sistêmico (LES), atendidos no Hospital Geral Universitário (HGU) Cuiabá/MT. Resultados: Dos 40 pacientes analisados, 42,5% apresentaram anemia. As médias dos valores de hematócrito e dosagem de hemoglobina nos pacientes com anemia foram respectivamente de 29,7% e 9,9 g/dL, ao passo que naqueles nos quais não se observou quadro anêmico a média de hematócrito foi de 41,1% e a de dosagem de hemoglobina 13,7g/dL. A anemia normocítica normocrômica foi a mais encontrada (64,7%) sendo observados, nessa situação, índices hematimétricos (VCM, HCM, CHCM e RDW) dentro dos valores de normalidade. As anemias macrocíticas e microcíticas tiveram a mesma representação percentual (17,6%). Alterações hematimétricas, tais como, RDW aumentado, policromasia e reticulocitose observadas em alguns pacientes sugerem a possibilidade de processos hemolíticos comumente observados nessa patologia.
