Evaluation of hematological parameters in patients using systemic isotretinoin with diagnosis of acne vulgaris

Abstract

ObjectivesOral isotretinoin is the most effective treatment option in patients with acne. However, it can cause various hematologic and biochemical abnormalities. This study aimed to evaluate hematologic abnormalities during oral isotretinoin treatment in patients with acne. Material and MethodsIn this cross-sectional study, the hematologic and inflammatory parameters of 138 patients with acne using 0.3-1 mg/kg/day oral isotretinoin for at least 6 months were retrospectively analyzed. ResultsIn the study, the female-to-male ratio was 2.83, and the mean age of the patients was 23.1 +/- 5.8 years. At the third and sixth months of isotretinoin treatment, there was a statistically significant decrease in the neutrophil count compared to the pre-treatment values (p = 0.003 and p = 0.032, respectively). The platelet count showed the most statistically significant increase (p < 0.001) at the first month of treatment. The most statistically significant decrease in the neutrophil-to-lymphocyte ratio (NLR) was observed at the third month of treatment (p < 0.001). No significant changes were observed in hemoglobin, hematocrit, white blood cell count, mean corpuscular volume, and mean platelet volume. ConclusionsThere was a decrease in neutrophils and NLR and an increase in platelets during isotretinoin treatment, and these changes were usually mild. However, it would be appropriate to monitor blood counts during treatment in patients with neutropenia or thrombocytosis.
