SIEDY Diagnostic Accuracy in Assessing Erectile Dysfunction in Young Men Living With HIV

Area of Science:

• Urology
• Infectious Diseases
• Cardiovascular Health

Background:

• Erectile dysfunction (ED) is a common comorbidity in men living with HIV.
• The Structured Interview of Erectile Dysfunction (SIEDY) assesses psychological, relational, and organic factors of ED.
• Dynamic penile color Doppler ultrasound (dPCDU) is a key diagnostic tool for vascular ED.

Purpose of the Study:

• To evaluate the reliability of the SIEDY questionnaire in identifying ED causes in young men with HIV.
• To compare SIEDY findings with objective vascular assessments using dPCDU.

Main Methods:

• Cross-sectional study of 50 young men (<50 years) with HIV and ED symptoms.
• Assessment using the International Index of Erectile Function-5 (IIEF-5) and SIEDY.
• Penile vascular assessment via dPCDU, with logistic regression analysis.

Main Results:

• 80% of participants had abnormal SIEDY scores, predominantly Scale 3 (psychological).
• 90% showed abnormal dPCDU findings, with increased intima-media thickness (IMT) being most common.
• No correlation between dPCDU and SIEDY Scale 1 (organic); IMT correlated with SIEDY Scales 2 (relational) and 3 (psychological).

Conclusions:

• SIEDY may underreport organic ED causes in men with HIV.
• dPCDU is essential for comprehensive ED evaluation, complementing subjective assessments.
• Integrating dPCDU into routine ED clinical practice is recommended for this population.
