RESUMEN
Safety of blood and blood products is a major problem all over the world. Screening for the markers of infectious diseases is an incomplete solution. One of the most important steps in improving the safety of blood and blood products is donor selection. In this study, causes of donor deferral were evaluated retrospectively in the blood center of a children's hospital. Analysis of the deferrals showed that the most commonly defined causes were recent sexual exposure in high-risk activity, recent ingestion of medication, low hemoglobin level, abnormal blood pressure, being underweight, tattoos, piercing or acupuncture in the preceding 6 months, recent history of infection and presenting for a subsequent donation too soon, elevation of transaminases, presence of the markers of the infectious diseases.

Brucella infections have a wide spectrum of symptoms especially in children, making the diagnosis a complicated process. The gold standard for the final diagnosis for brucellosis is to identify the Brucella spp. isolated from blood or bone marrow cultures. The main purpose of this work was to evaluate the factors affecting the isolation of Brucella spp. from blood cultures. In our study, the ratio of fever, presence of hepatomegaly, and splenomegaly were found to be higher in the bacteremic group. In addition, C-reactive protein levels and liver function enzymes were found to be higher in the bacteremic group. In our opinion, while evaluating the febrile child with suspected Brucella infection, we highly recommend sampling blood cultures regardless of the history of previous antimicrobial therapy and duration of the symptoms.
