Abstract: The objective of this study is to investigate the relation between serum lipids (cholesterol, LDL, HDL, triglyceride (TG)) and erectile dysfunction (ED). The experimental methods involved comparison of 100 patients with organic ED (mean age of 43.59+/-10.51 y), with 100 healthy individuals (mean age of 43.72+/-9.76 y) regarding their lipid profile from January 2000 to June 2003 (cholesterol, TG, HDL, LDL). The results showed that there was a significant difference between mean plasma cholesterol and LDL levels in the individuals suffering from ED and the control group (P=0.04 and 0.02, respectively). The TG and HDL mean plasma level differences were not significant (P=0.583 and 0.299, respectively). Odds ratios for high plasma cholesterol level (>240 mg/dl) and high plasma LDL level (>160 mg/dl) were 1.74 and 1.97. The R2 was 0.04 for both cholesterol and LDL. Applying linear regression, the coefficient for cholesterol and LDL reduced the International Index of Erectile Function questionnaire scores by -0.036 and -0.035. In conclusion, this study, the correlation of cholesterol and LDL levels with ED strongly supports the role of hyperlipidemia treatment in both the prevention and management of ED.

Abstract: OBJECTIVE: The present study focuses on testing the association of hostility with plasma homocysteine levels in a general population sample. METHOD: Four hundred and ten healthy adults (200 men and 210 women), participating in a health survey in Greece, had blood samples taken for homocysteine concentrations and also completed a multidimensional hostility questionnaire, assessing direction of hostility ('extra- and intropunitive') as well as total hostility and its ingredients, i.e. urge to act out hostility, criticism of others, delusional hostility, self-criticism and delusional guilt. Multivariate relationship was tested between hostility components and homocysteine, after statistically controlling for potential confounders such as age, gender, educational status, smoking and body mass index. RESULTS: Total hostility, delusional guilt as well as extrapunitive direction of hostility were positively related to homocysteine levels. Self-criticism was negatively related to homocysteine. CONCLUSION: The study provides further evidence that particular dimensions of hostility are associated with increased plasma homocysteine levels, thus deserving a place within the spectrum of the coronary heart disease risk factors.
