RESUMO
OBJECTIVES: We aimed to evaluate the effect of daily 5 mg tadalafil on the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio (PLR) in patients with erectile dysfunction (ED). PATIENTS AND METHODS: 30 subjects with ED were given tadalafil as well as 30 subjects with ED who were not receiving tadalafil were recruited. 30 healthy individuals served as controls. RESULTS: Receiver operating characteristic curve (ROC) showed that the best cut off point of pre-treatment and post treatment NLR in the ED treatment group was found <1.51, <1.51, sensitivity of 68.3%, 58.3%, specificity of 53.3%, 53.3%, lower bound of 0.558, 0.517, upper bound of 0.789, 0.757, total accuracy of 67.4%, 63.7% and p 0.003, 0.0025, respectively. Additionally, the best cut off point of pre-treatment and post treatment PLR in the ED treatment group was found <5.89, <5.99, sensitivity of 65%, 63.3%, specificity of 63.3%, 53.3%, lower bound of 0.515, 0.435, upper bound of 0.755, 0.687, total accuracy of 63.5%, 56.1% and p 0.027, 0.341, respectively. CONCLUSION: Daily 5 mg Tadalafil supplementation significantly improves erectile function through decreasing these markers as well as depression and anxiety.
