Severe hypocalcemia is common in acute leukemia patients with infections. This condition indicates a poor prognosis and requires careful monitoring and treatment.

Area of Science:

Oncology
Internal Medicine
Clinical Pathology

Background:

Acute leukemia patients are susceptible to metabolic disturbances.
Severe hypocalcemia can be a critical complication in these patients.

Purpose of the Study:

To investigate the incidence and clinical significance of severe hypocalcemia in adults with acute leukemia.
To identify risk factors and outcomes associated with hypocalcemia in this population.

Main Methods:

Retrospective analysis of 54 adult acute leukemia patients over 20 months.
Monitoring of serum calcium levels, infection status, and clinical outcomes.

Main Results:

Eighteen patients (33%) developed severe hypocalcemia (mean lowest serum calcium 6.3 mg/100 ml).

Hypocalcemia was symptomatic in most patients and associated with severe gram-negative infections.

Hypocalcemia was linked to increased mortality and complications like respiratory arrest.

Conclusions:

Frequent serum calcium monitoring is crucial for acute leukemia patients, especially during infection.
Severe hypocalcemia is a marker of poor prognosis, necessitating vigilant observation and management.
Caution with certain antibiotics and prompt calcium administration are recommended.
