Abstract
BACKGROUND N-3 polyunsaturated fatty acids (LCPUFA-ω3), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) might have beneficial effects on lean mass and fat mass synthesis. OBJECTIVE To investigate the effect of LCPUFA-ω3 supplementation on body composition changes in children with acute lymphoblastic leukemia (ALL) at remission and three months (3 mo) after supplementation. METHODS This randomized controlled trial enrolled 72 children (3-13 y) with newly diagnosed ALL (placebo group [500 mg sunflower oil]: 36 patients; LCPUFA-ω3 group [225 mg DHA, 45 mg EPA]: 36 patients). LCPUFA-ω3 was administered at 0.100 g/kg of body weight/day for 3 mo. Both groups were provided with an oral milkshake supplement. MAIN OUTCOMES AND MEASURES Body composition was measured at diagnosis, remission, and 3 months after supplementation by dual-energy X-ray absorptiometry (DXA). Red blood cell fatty acid analyses were performed with gas chromatography. Student's t test compared the percentage changes in body weight, total body fat percentage (TBFP), and lean body mass (LBM) between the groups. The Mann-Whitney U test was used to compare the groups, and the Friedman range test and Wilcoxon signed rank test were used for intratreatment comparisons. Spearman correlation coefficients were calculated for LBM and erythrocyte LCPUFA-ω3 content. RESULTS LBM decreased significantly in both groups. This loss was greater in the placebo group than in the LCPUFA-ω3 group at remission (p = 0.044) and at 3 months of supplementation (p = 0.039). There were significant and progressive increases in DHA and EPA concentrations in the LCPUFA-ω3 group (p < 0.001). LBM at remission was directly correlated with increased DHA (r = 0.487, p = 0.034) and EPA (r = 0.499, p = 0.030) erythrocytes in the LCPUFA-ω3 group. CONCLUSION At ALL diagnosis and during the first three months of treatment, 100 mg/kg of body weight/d DHA and EPA decreased LBM loss and allowed the incorporation of fatty acids into cell membranes (clinicaltriasl.gov #: NCT01051154).

Abstract
Acute lymphoblastic leukemia (ALL) has been recognized as a hematologic neoplasia that originates at the level of a primitive lymphoid stem/progenitor cell. To date, however, the biology of the hematopoietic system in this disorder is still not fully understood. In the present study, we have determined the progenitor cell content (including myeloid, erythroid and multipotent progenitors) in 14 children with ALL and followed the proliferation kinetics of these cells in Dexter-type long-term marrow cultures. We have also characterized some aspects related to the composition and function of the hematopoietic microenvironment developed in vitro. All patients included in this study showed extremely reduced levels of progenitor cells (median of 6.2% of the levels found in normal marrow). Proliferation of these cells in long-term cultures was markedly deficient, since they showed very low numbers - compared to normal cultures - and reached undetectable levels after only a few weeks. Regarding the microenvironment developed in vitro, whereas normal marrow samples contained a median of 8 fibroblastic progenitors/10(5) marrow cells and the stromal cell layers developed in culture contained a median of 341000 adherent cells per well, ALL marrow samples showed no fibroblastic progenitors and the numbers of adherent cells were 21% of those in normal cultures. Interestingly, the levels of TNFalpha and IL-6 in ALL culture supernatants were significantly increased, compared to normal cultures. Bone marrow samples from all 14 children were also analyzed once they reached a complete clinical and hematological remission. Myeloid, erythroid and multipotent progenitor cell levels were significantly increased, compared to patients at diagnosis, and proliferation of myeloid progenitors in long-term cultures was also improved. In contrast, proliferation of erythroid progenitors showed no difference to that in cultures from patients at diagnosis. The numbers of fibroblastic progenitors and adherent cells were significantly increased, compared to patients at diagnosis, and TNFalpha and IL-6 levels returned to normal. In summary, in the present study, we have demonstrated significant in vitro alterations of the hematopoietic system, both in terms of its composition and function, in pediatric patients with ALL. Importantly, most of these alterations are corrected, at least partially, after chemotherapy.

Abstract
We have characterized the proliferation kinetics of hematopoietic cells in long-term marrow cultures (LTMC) from five normal children and seven children with congenital bone marrow failure (four with Fanconi anemia [FA] and three with congenital pure red cell aplasia [PRCA]). Total nonadherent and adherent cells, as well as nonadherent progenitors, were determined weekly in the presence or in the absence of rhGM-CSF (10 ng/ml) or rhEPO (3 U/ml). As compared to normal LTMC, hematopoiesis was drastically reduced in cultures from FA patients. Myeloid and erythroid progenitor cells reached undetectable levels after only 3 and 1 weeks of culture, respectively. This was observed even in cultures supplemented with rhGM-CSF, in which no response to this cytokine occurred. In LTMC from PRCA children, the growth of erythroid and multipotent progenitors was also drastically reduced. Myelopoiesis, on the other hand, showed normal levels during the first three weeks of culture; however, from week 4, there was a significant decrease in the levels of both progenitor and mature cells, reaching undetectable levels several weeks before normal cells did. Response to rhGM-CSF and rhEPO was transient and deficient. Our results suggest that in FA, alterations at the level of primitive progenitor cells are so severe that myeloid, erythroid and multipotent progenitors are unable to proliferate in LTMC, even in the presence of rhGM-CSF. In patients with PRCA the erythroid arm of hematopoiesis is preferentially affected and addition of rhGM-CSF and/or rhEPO to these cultures had little or no effect on erythroid cell production. Interestingly, myelopoiesis in this culture system was deficient as well and response to rhGM-CSF was defective, suggesting that the myeloid lineage is also altered in congenital PRCA.
