title: Sex and the PASI: patients affected by a mild form of psoriasis are more predisposed to have a more severe form of erectile dysfunction.
abstract: BACKGROUND
  Psoriasis is a multi-systemic disease involving the skin and joints, but it is also characterized by endothelial dysfunction, which may cause sexual impotence and erectile dysfunction (ED), an embarrassing disease frequently neglected by dermatologists.
  
  
  OBJECTIVE
  The principal objective was assessing the relationship between the severity of psoriasis and the severity of ED. We also investigated whether severity of psoriasis was related to International Index of Erectile Function-5 (IIEF-5) score, whether genital lesions worsened the IIEF-5 score, whether ED was related to factors such as diabetes, smoking and hypertension, and finally the overall the psychological factors felt by the patient.
  
  
  METHODS
  We administered two questionnaires (one of which was the IIEF-5, a validated score to assess erectile dysfunction) to three groups of patients: 60 with mild psoriasis, 60 with severe psoriasis (assessed by Psoriasis Area Severity Index, PASI) and a control group including 60 patients without the disease.
  
  
  RESULTS
  In the group of mild psoriasis, the patients who suffered from ED were the 56.67%, while in the group of severe psoriasis, ED affected the 46.68% of subjects. In the control group, ED was reported by the 23.33% of patients. The average IIEF-5 score was 18.81 for patients with mild psoriasis and 20.31 for patients with severe form. The difference in the average IIEF-5 scores between psoriatic (mild and severe cases) and control group was not statistically significant. Most patients with sexual dysfunction had also genital lesions; diabetes, smoking and hypertension were not related to lower IIEF-5 scores. The overall psychological profile of psoriatic patients was worse than that of the controls.
  
  
  CONCLUSIONS
  We concluded that ED was related to psoriasis, in particular to mild forms. Moreover, since ED is a marker of cardiovascular events, also related to negative impact on the quality of life, physicians should always investigate the presence of ED in clinical practice.
