Insights

Folate deficiency is common in children with acute lymphoblastic leukemia (ALL) undergoing maintenance chemotherapy in India. This deficiency increases the risk of treatment complications and mortality, highlighting the need for further research into supplementation.

Area of Science:

  • Pediatric Oncology
  • Hematology
  • Nutritional Science

Background:

  • Treatment-related toxicity and mortality are significant concerns during maintenance chemotherapy for childhood acute lymphoblastic leukemia (ALL), particularly in low- and middle-income countries (LMICs).
  • Undernutrition and micronutrient deficiencies are prevalent in children undergoing ALL treatment in LMICs.
  • This study investigates the prevalence and clinical impact of folate deficiency in North Indian children with ALL during maintenance therapy, considering antifolate drug use and high population folate deficiency rates.

Purpose of the Study:

  • To examine the prevalence of folate deficiency in children with ALL during maintenance chemotherapy.
  • To assess the clinical implications of folate deficiency, including treatment complications and mortality.
  • To explore the association between folate deficiency and adverse outcomes in this patient population.

Main Methods:

  • Assessed pre-cycle folate levels and deficiency in children with ALL.
  • Determined weight-for-age z-scores and serum albumin levels.
  • Correlated folate status with treatment complications and mortality during maintenance therapy.

Main Results:

  • Folate deficiency was identified in 29 of 52 children during maintenance chemotherapy.
  • Folate-deficient children experienced significantly higher rates of neutropenia, thrombocytopenia, febrile neutropenia, and chemotherapy dose reductions.
  • Folate deficiency was associated with increased maintenance deaths and lower survival rates, and independently linked to febrile neutropenia and mortality.

Conclusions:

  • Folate deficiency is a significant risk factor for treatment complications and adverse outcomes in children with ALL undergoing maintenance chemotherapy.
  • The potential benefits and risks of folate supplementation in deficient children require investigation through well-designed randomized trials in similar settings.

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Vitamins01:30

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...

Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...
