Introduction. Although Peyronie's Disease (PD) was first described over 250 years ago, its precise etiology remains obscure.
Aim. Analyze a variety of potential associated factors with PD, including erectile dysfunction.
Materials and Methods. This cross-sectional study included 83 consecutive men with PD and 252 age-matched controls. All men completed the International Index of Erectile Function (IIEF) and were evaluated regarding their clinical and demographic characteristics, comorbidities, and used medications. Anthropometric measures included body mass index and waist circumference (WC). Fasting blood glucose, lipid profile, total testosterone, and dehydroepiandrosterone-sulfate were determined.
Main Outcome Measures. Clinical and laboratory characteristics associated to PD.
Results. The mean age was 59.2 ± 10 years in the cases and 59.7 ± 12 years in the controls. Marital status, current smoking, and excessive consumption of alcoholic beverages were similar between groups (P > 0.05). PD was more common among white skin color males (P = 0.001). The mean score for each IIEF domain and the androgen levels were similar in the two groups. Thiazides were the only medication associated to PD (P = 0.03). Dupuytren's disease was more frequent among individuals with PD (P = 0.001). The distribution of all other comorbidities investigated was similar between groups (P > 0.05). The characteristics WC > 102 cm and levels of low-density lipoprotein (LDL) > 130 mg/dL were more prevalent in the controls (P < 0.05). After multivariate analysis, white skin color (OR: 8.47, 95%CI: 1.98–36.24) and thiazide use (OR: 2.29, 95%CI: 1.07–4.90) were associated to PD, and LDL > 130 mg/dL (OR: 0.55, 95%CI: 0.32–0.92) and WC > 102 cm (OR: 0.53, 95%CI: 0.29–0.96) were inversely associated to PD.
Conclusions. In this study, PD was more common among white skin colored males. An inverse relationship with the presence of elevated serum levels of LDL and WC was observed. We found no association with medications other than thiazides and comorbidities other than Dupuytren's disease. Androgen serum levels and sexual dysfunction had also no association to PD.
