To investigate a potential causal link between long-term voglibose use and persistent leukopenia in a diabetic patient, highlighting the rarity of such an association.
Key Findings:
The patient's white blood cell count increased from 2.69–3.32 × 10^9/L to 3.89–3.98 × 10^9/L two weeks after switching to acarbose, indicating a positive response to the intervention.
A Naranjo score of 7 indicated a probable causal relationship between voglibose and leukopenia, suggesting a need for further investigation into drug-induced cytopenias.
Interpretation:
This case suggests that voglibose may rarely induce chronic leukopenia, particularly with prolonged use, emphasizing the need for awareness among clinicians.
Limitations:
The findings are based on a single case study, limiting generalizability.
Other potential causes of leukopenia were ruled out but may not encompass all possibilities.
Lack of long-term follow-up data post-intervention limits understanding of the sustained effects.
Conclusion:
Clinicians should consider medication review and therapeutic substitution in diabetic patients with unexplained cytopenia, along with specific monitoring strategies for white blood cell counts.
