Influenza B virus triggering macrophage activation syndrome in an infant

We report a 10-month-old female infant with fever, convulsions, and hepatosplenomegaly. Laboratory data of bicytopenia, low erythrocyte sedimentation rate, and elevated liver enzymes suggested MAS. This was supported by the presence of hyperferritinemia with hypertriglyceridemia. MAS was triggered by influenza B virus. She responded to treatment with immunoglobulin and steroid.
