[Non-Hodgkin lymphoma: Excellent results at the expense of the high toxicity of the treatment]. / Linfoma no Hodgkin: excelentes resultados a expensas de elevada toxicidad del tratamiento.

INTRODUCTION: Lymphomas are the third malignancy in children, and within them non-Hodgkin lymphoma (NHL) accounts for just 7% of cancers in children under 15 years old. Chemotherapy is currently the treatment of choice. The objective of this study is to analyze the toxicity caused by the treatment in pediatric patients diagnosed with NHL. MATERIAL AND METHODS: A retrospective study was conducted on patients diagnosed with mature B-cell NHL, treated according to the LMB protocol 2001, from January 2007 to February 2014. Data concerning the diagnosis, treatment and toxicities that developed in the patients during the same period were collected. RESULTS: A total of 20 mature B-cell NHL cases were diagnosed: 16 Burkitt lymphomas, 2 diffuse large cell lymphomas and 2 mature leukemias. Almost two-thirds (65%) of patients were classified in a high grade stage (iii-iv) at diagnosis. Serious infectious processes, severe myelosuppression, liver abnormalities, and mucositis were the most frequent toxicities. Overall survival was 95% (19/20). One patient died of causes unrelated to the illness. CONCLUSION: Despite the excellent survival rate, most patients diagnosed with NHL mature B cells experience grade iii and iv toxicities during treatment.

Effects of parenteral nutrition formulas on plasma lipid profile in children with bone marrow transplantation.

BACKGROUND/AIMS: Children undergoing bone marrow transplantation (BMT) often require parenteral nutrition (PN). This is a comparative study of plasma lipid profiles in BMT children after fish oil or soybean PN. METHODS: A total of 14 children with BMT requiring PN for at least 10 days were recruited during 24 months. They were randomized to receive a lipid emulsion enriched with ω3 polyunsaturated fatty acid, or soybean oil. Clinical monitoring was performed. Blood samples were collected before and after administration of PN to analyze the lipid profile. RESULTS: There were no complications associated with PN. The increase in TG levels was more pronounced after administration of an enriched ω3 emulsion and the decrease in cHDL and apo A was greater after administration of soybean. The ω3 group showed an increase in eicosapentaenoic and a decrease in arachidonic acids compared to the soybean group. Both groups showed similar levels of linolenic acid. CONCLUSION: PN with soybean or ω3 emulsions for 10 days is safe in children. However, research in children are necessary in order to examine the impact of the duration of PN and the type of lipid formula used, and determine their health benefits in relation to the fatty acid profile.
