    High-dose chlorpropamide therapy can cause pure red blood cell aplasia, a rare condition. Stopping the drug led to a full recovery of hemoglobin levels in a reported case.

    Area of Science:

    • Hematology
    • Pharmacology

    Background:

    • Pure red blood cell aplasia (PRCA) is a rare anemia characterized by the selective absence of erythroid precursors in the bone marrow.
    • Drug-induced PRCA is an uncommon but serious adverse effect of certain medications.

    Observation:

    • A 70-year-old male patient developed PRCA following high-dose chlorpropamide treatment.
    • This represents the second documented instance of chlorpropamide-induced PRCA.

    Findings:

    • Discontinuation of chlorpropamide therapy resulted in a rapid and sustained normalization of hemoglobin levels.
    • The patient achieved a complete hematologic recovery after drug cessation.

    Implications:

    • Chlorpropamide should be considered a potential cause of drug-induced PRCA.

  • Awareness of this association is crucial for clinicians managing patients on chlorpropamide, particularly at high doses.
  • Prompt recognition and withdrawal of the offending agent are key to successful management of PRCA.
