Iron deficiency anemia in children presenting with lymphoreticular malignancies and the effect of induction therapy.

There is scant information regarding iron deficiency in children with malignant disorders. Serum iron status of children with lymphoreticular malignancies (LRMs) at onset and at the end of induction therapy, compared to the normal population, was evaluated. Prospective cohort study conducted between July 2002 and March 2004. Previously untreated children recently diagnosed with LRM were studied. Age-matched controls were enrolled from follow-up and growth monitoring clinics. Hematological (complete blood counts and red cell indices) parameters and markers of iron status (serum iron, serum ferritin, total iron binding capacity) were estimated at presentation and at the end of remission induction therapy, that is, 5 weeks after initial evaluation. Bone marrow iron store were only assessed in cases. Thirty-five children (31 with acute lymphoid leukemia, 2 with acute myeloid leukemia, and 2 with non-Hodgkin lymphoma; 27 boys and 8 girls; 2 to 12 years of age) were evaluated in the study cohort. Anemia was documented in 80% of children with LRM. Iron deficiency was an important etiological factor. In the majority of cases therapy resulted in significant improvement towards normalization of deranged hematological parameters. This phenomenon could be attributed to enhanced quantity and quality of erythropoietic activity and red cell transfusions. The observation suggests that therapeutic iron supplements are not indicated in the majority of children on therapy for malignant disorders. Various hematological and body iron status parameters should be assessed on a case-by-case basis.

Effect of maternal low dose aspirin on neonatal platelet function.

OBJECTIVE: To evaluate the effect of maternal low dose aspirin ingestion in platelet function of newborn. DESIGN: Prospective randomized placebo controlled study. METHODS: 25 neonates born to mothers receiving low dose aspirin and 25 matched neonates with no maternal exposure to aspirin were studied. 2 ml of EDTA and 4.5 ml of citrate blood was collected from umbilical vein using double clamped umbilical stump for hemogram, coagulation profile and platelet functions. RESULTS: The platelet counts (10(9)/l) of study and control groups were 186.4 +/- 22.76 (116-225) and 205.28 +/- 17.34 (176-225), respectively. There was no significant difference in coagulation parameters. Prothrombin time index (PTI) was 86.24 +/- 6.623 and 87 +/- 6.43, respectively in the study and control group while PTTK (sec) was 55.88 +/- 20.54 and 52.12 +/- 11.82 in study and control subjects, respectively. The platelet aggregation studies (platelet function) with various platelet agonists in study and control group did not show any significant difference. Clinically, none of the babies had bleeding. CONCLUSIONS: Use of low dose aspirin in pregnant women was found to be safe and had no adverse effects on platelet functions of newborn.
