Pediatric lupus: varied haematological picture and presentation

Abstract

Systemic lupus erythematosus (SLE) is a chronic, multisystem, autoimmune disease characterized by periods of increased disease activity caused by inflammation of blood vessels and connective tissue. Pediatric patients with SLE have a more severe clinical course when compared with adults. Patients commonly present with rash, fever, and arthritis, although the presentation may be unpredictable. Hematological findings are more predominant in children than adults. Thirty-nine percent of children with SLE will develop hematological abnormalities, one of the American Rheumatic Association criteria for classifying the disease. In our case series we found varied hematological picture and presentation. We present here four case reports of SLE cases with interesting hematological features. Our first case is a 13 month old female child who was initially diagnosed as Evans syndrome and 2 years later diagnosed as SLE. Second case is a 3 year old male child who had SLE with warm antibody AIHA. Third case is a 6 year old female child who presented with AIHA and was diagnosed with SLE 6 years later. Fourth case is a 6 year old female child diagnosed as SLE with aplastic anemia. Hematological findings should be carefully assessed and treated in order to decrease disease related morbidity.
