Abstract

We evaluate the correlation between the plasma level of C-reactive protein (CRP) in patients with erectile dysfunction (ED) and hypertension and to set up whether the CRP level affected by the treatment of vardenafil 10 mg orally once daily. A total of 116 male patients with ED and hypertension were enrolled in this prospective study. The patients were divided into two groups, group 1 (ED patients with Not controlled hypertension) and group 2 (ED patients with controlled hypertension). All patients completed the International Index of Erectile Function (IIEF) scores, performed a penile color Doppler ultrasound examination and high sensitivity (hs-CRP) levels. The patients were given vardenafil 10 mg once daily for 3 months and reassessed again. According to the IIEF-EF domain score, there were statistically significant differences between the two groups (P = 0.012) with a median value 10.0 (4.0–14.5) and 15.0 (9.0–16.5) between group 1 and group 2, respectively. Regarding to the severe (score < 11), moderate (score 11–16) and mild (score 17–25) there were statistically significant differences between the two groups (0.023), (0.001) and (0.001), respectively. The hs-CRP showed statistically significant difference between the two groups (P = 0.050) with a median value 2.4 (1.5–3.1) and 1.8 (1.1–2.4) between group 1 and group 2, respectively. The peak systolic velocity (PSV) and end diastolic velocity (EDV) showed statistically significant differences between the two groups (P = 0.011) and (P = 0.046), respectively. After treatment, there were improvements in the IIEF-EF domain score, severe (score<11), moderate (score 11–16), mild (score 17–25), PSV and EDV in both groups and these improvement were more obvious in (group 2) than (group 1) with a statistically significant differences between the two groups (P<0.05) (except in moderate (score 11–16), no statistically significant difference). The hs-CRP showed statistically significant differences between the two groups after treatment (P = 0.049) with a median 2.1 (1.6–2.9) and 1.2 (0.9–2.4) between group 1 and group 2, respectively. Serum hs-CRP was significantly elevated in patients with ED and not controlled hypertension than in ED patients with controlled hypertension. ED patients with controlled blood pressure gave better results with penile duplex than those with not controlled blood pressure. Serum hs-CRP level could be a marker for an endothelial condition in men with ED and hypertension.
