ReviewThe role of biomarkers in the early detection of anthracycline-induced cardiotoxicity in children: a review of the literature.
Anthracycline-induced cardiotoxicity can cause serious health problems for an increasing number of children surviving childhood malignancies. Early detection of cardiac failure is critically important for the prevention and management of anthracycline-induced cardiotoxicity. ⋯ Six of 14 studies in children showed a significant relation between elevated biomarkers BNP, NT-pro-BNP, and cTnT and cardiac dysfunction. Six studies, although small, suggest that BNP, NT-pro-BNP, and cTnT might be useful markers in the early detection of anthracycline-induced cardiotoxicity.

Comparative StudyRecombinant human erythropoietin beta therapy: an effective strategy to reduce transfusion requirement in children receiving anticancer treatment.
In recent years erythropoietic agents have become important tools in the management of anemia in cancer patients, improving hemoglobin (Hb) concentrations, reducing the need for transfusion, and enhancing quality of life. In this prospective and historically controlled study, the effects of epoetin beta on Hb concentrations and red blood cell transfusion needs in children with cancer receiving chemotherapy or radiotherapy have been investigated. Epoetin beta (150 U/kg/day, 3 days a week) was given subcutaneously to 22 children with cancer when Hb concentration < or = 10 g/dL. ⋯ Epoetin beta therapy provides significant increase in Hb concentrations in children with cancer under anticancer treatment, especially after the sixth week of therapy. Administration of epoetin beta prevents profound decreases in Hb concentrations in the course of therapy and effectively reduces the need for red blood cell transfusions. Epoetin beta was found to be safe and effective in the dosage and the scheme it was used in our study.

Pulmonary function test in transfusion-dependent beta-thalassemia patients.
Beta-thalassaemia is the most common hemoglobinopathies in our region with treatment of regular blood transfusion. Iron overload and hemosiderosis can cause organ involvement. Recent studies have focused on pulmonary involvement and pathophysiology of lung damage. ⋯ The authors conclude that the lung may be considered a site for organ damage, and alteration of pulmonary function may be expected in transfusion-dependent patients in spite of no pulmonary symptoms or normal CXR. In recent years, because of new iron chelating drugs, doctors can expect thalassemic patients to have a long life-time and need to increase their quality of life. One way to do this is to evaluate the respiratory system by PFT to prevent the squeal of pulmonary disease.
