[Electrolytic changes in children with acute lymphoblastic leukemia during remission induction]

Area of Science:

• Pediatric Oncology
• Clinical Chemistry
• Hematology

Background:

• Water-electrolyte balance disturbances are frequent early complications in children with acute lymphoblastic leukemia (ALL).
• These imbalances can arise from the leukemia itself or its treatment regimens.

Purpose of the Study:

• To investigate the incidence and types of water-electrolyte balance alterations in pediatric ALL patients during remission induction therapy.
• To assess the impact of specific chemotherapy agents on electrolyte levels.

Main Methods:

• A cohort of thirteen pediatric ALL patients (aged 1.5-14 years) received standard remission induction therapy.
• Blood samples were collected pre-treatment and on days 2 and 6 of therapy.
• Assays included sodium, potassium, calcium, phosphate, magnesium, albumin, urea nitrogen, creatinine, and uric acid.

Main Results:

• Significant alterations observed: hyponatremia (4/13), hypokalemia (9/13), hypomagnesemia (9/13), hypocalcemia (11/13), hypophosphatemia (9/13), hypouricemia (3/13), and hyperuricemia (3/13).
• No patients developed acute renal insufficiency.
• Electrolyte abnormalities were noted during the early phase of treatment.

Conclusions:

• Pediatric ALL treatment, including agents like epirubicin and methotrexate, is associated with a high prevalence of water-electrolyte imbalances.
• These findings highlight the need for vigilant monitoring of electrolyte status in children undergoing ALL therapy.
• The observed abnormalities may be multifactorial, related to both the disease and its management.
