Effects of Isotretinoin on the Platelet Counts and the Mean Platelet Volume in Patients with Acne Vulgaris

Abstract EN

Aim.

The aim of this study was to evaluate the platelet counts and the mean platelet volume in patients who received isotretinoin for the treatment of acne vulgaris.

Method.

A total of 110 patients were included in this retrospective study.

Complete blood count parameters were recorded prior to and three-months following the treatment.

Results.

Both platelet counts and the mean platelet volume were significantly decreased following the treatment.

No significant differences were noted on the levels of hemoglobin, hematocrit, and white blood cell count.

Conclusion.

Platelet counts and mean platelet volume significantly decreased following isotretinoin treatment.

Since the decrease of platelet counts and the mean platelet volume was seen concomitantly, it is concluded that the effect of isotretinoin was through the suppression of bone marrow.
