RESUMO

OBJECTIVES: To explore the risk factors associated with cow's milk protein allergy (CMPA) in infants. METHODS: This study was a multicenter prospective nested case-control study conducted in seven medical centers in Beijing, China. Infants aged 0-12 months were included, with 200 cases of CMPA infants and 799 control infants without CMPA. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the occurrence of CMPA. RESULTS: Univariate logistic regression analysis showed that preterm birth, low birth weight, birth from the first pregnancy, firstborn, spring birth, summer birth, mixed/artificial feeding, and parental history of allergic diseases were associated with an increased risk of CMPA in infants (P<0.05). Multivariate logistic regression analysis revealed that firstborn (OR=1.89, 95%CI: 1.14-3.13), spring birth (OR=3.42, 95%CI: 1.70-6.58), summer birth (OR=2.29, 95%CI: 1.22-4.27), mixed/artificial feeding (OR=1.57, 95%CI: 1.10-2.26), parental history of allergies (OR=2.13, 95%CI: 1.51-3.02), and both parents having allergies (OR=3.15, 95%CI: 1.78-5.56) were risk factors for CMPA in infants (P<0.05). CONCLUSIONS: Firstborn, spring birth, summer birth, mixed/artificial feeding, and a family history of allergies are associated with an increased risk of CMPA in infants.

RESUMO

OBJECTIVE: To study the changes of minimal residual disease (MRD) in children with B cell acute lymphoblastic leukemia (B-ALL) of different genetic abnormalities. METHODS: Between February 2004 and April 2013, 271 newly diagnosed B-ALL pediatric patients who had finished the induction chemotherapy were enrolled in the study. The characteristics of changes in MRD in patients with different genetic abnormalities on the 15th day and at the end of the induction therapy were analyzed. RESULTS: On the 15th day of the induction chemotherapy, the MRD positive proportion in patients with hyperdiploid was higher on all the three cut-off levels of MRD≥0.1%, 1% and 10% compared to patients without hyperdiploid (P<0.05), but there was no significant difference in the MRD positive proportion on the three levels of MRD between the TEL-AML1-positive and TEL-AML1-negative groups (P>0.05). On the end of induction chemotherapy, there was no significant difference in the MRD positive proportion on the three levels of MRD between the patients with and without hyperdiploid (P>0.05), neither between the BCR-ABL-positive and negative groups. The MRD positive proportion in TEL-AML1-negative patients was significantly higher than in TEL-AML1-positive patients on all three levels of MRD (P<0.05). The MRD positive proportion on two levels of MRD≥0.01% and 0.1% in E2A-PBX1-negative patients was significantly higher than in E2A-PBX1-positive patients (P<0.05). CONCLUSIONS: Children with B-ALL of different genetic abnormalities have different MRD levels during, and at the end of, induction therapy. The prognostic significance of MRD may be related to the genetic abnormalities.
