The effect of using tadalafil 5 mg/day on neutrophil–lymphocyte and platelet–lymphocyte ratios in mild‐medium and severe erectile dysfunction patients; and comparison of clinical response
Abstract
To examine the relation between NLR (neutrophil–lymphocyte ratio) and PLR (platelet–lymphocyte ratio) rates and the severity of ED (erectile dysfunction) and the effect of tadalafil 5 mg/day on these, a total of 143 patients were retrospectively evaluated. Sixty‐three patients with ED who came for follow‐up examinations in the 1st month of the treatment were included as the study group, and 80 men who were not diagnosed with ED were as the control group. The age and Charlson Comorbidity Indexes (CCI) of the study and control groups were compared with the IIEF 5, NLR and PLR values before and after the treatment. The mean age and median CCI were higher in the severe ED group (p < 0.05). The mean NLR and PLR values were lower in the control group (p < 0.001). In the study group, the NLR and PLR values decreased with the increase in the IIEF 5 scores (p < 0.001). The ROC curve was significant for the NLR and PLR scores (AUC = 0.779, [95% CI: 0.698–0.860]; AUC = 0.754, [95% CI: 0.670–0.838] p < 0.001). Although more prospective and randomized studies are needed, the systemic inflammation decreases and the clinical symptoms improve in patients who use tadalafil 5 mg/day.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 143 participants or records.
