[Low-dose PDE5 inhibitors for erectile dysfunction with subclinical metabolic syndrome].
2019
Objective To investigate the effects of low-dose PDE5 inhibitors on metabolic parameters and erectile function in ED patients with subclinical metabolic syndrome (SCMS). Methods Totally, 132 ED patients, aged 21-61 (mean 34.5) years, were treated in the Andrology Clinic of the First Hospital of Wenzhou Medical University from April 2017 to May 2018. According to the diagnostic criteria, we divided the patients into groups A (simple ED, n = 40), B (ED with SCMS, n = 34) and C (ED with MS, n = 58) to receive 3 months of oral administration of tadalafil at 5 mg qd at bedtime, and followed them up for 3 months after drug withdrawal. During the treatment, we advised the patients to keep a healthy diet, change bad habits, participate in regular physical exercise, and maintain psychological balance. Before and right after medication and at 3 months after drug withdrawal, we recorded the changes in the IIEF-5 scores, abdominal circumference, blood pressure and levels of fasting blood sugar (FBS), triglyceride (TG) and high-density lipoprotein (HDL) of the patients. Results The IIEF-5 scores showed statistically significant differences at different time points between groups A and C (P 0.05) or B (P > 0.05). Diastolic blood pressure was markedly lower in group B right after medication and at 3 months after drug withdrawal than before treatment ([75.62 ± 10.70] and [74.65 ± 9.90] vs [78.00 ± 11.42] mmHg, P 0.05). There were statistically significant differences in the FBS level among different time points in groups A and C (P 0.05), and so were there in the TG level among different time points in groups A and C (P 0.05). Conclusions Periodic administration of low-dose sustained-release PDE5 inhibitors with health education and lifestyle guidance may reverse ED with SCMS and improve most of the related metabolic parameters.
