Use of hematological parameters in evaluation of treatment efficacy in cutaneous leishmaniasis

Öz Objective: In the present study we investigated the role of hematological parameters, including neutrophil/lymphocyte ratio and platelet/lymphocyte ratio, mean platelet volume and platelet distribution width in the evaluation of treatment efficacy in adult patients diagnosed with cutaneous leishmaniasis.Methods: The study group included 45 adult patients diagnosed with cutaneous leishmaniasis and treated as inpatients in the dermatology clinic between 2011 and 2014. A group of 45 healthy adults served as a control group.Results: Pre- and post-treatment white blood cell count, neutrophils, and lymphocytes were significantly reduced among the patient group relative to the control group. Platelet distribution width, red cell distribution width, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio were significantly elevated among the patients compared to the healthy subjects. Pre-treatment white blood cell, lymphocyte and platelet counts were significantly elevated compared to post-treatment counts among the patient cohort. Treatment was associated with reduced eosinophil count, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio relative to pre-treatment status.Conclusion: Routine hematological testing results such as platelet/lymphocyte ratio, white blood cell count, neutrophil count, red cell distribution width, platelet distribution width, and mean platelet volume may be clinically significant markers of the inflammatory state useful in the evaluation of early treatment efficacy among patients with cutaneous leishmaniasis.
