Latent tuberculosis infection among patients with erectile dysfunction

Area of Science:

• Urology
• Infectious Diseases
• Cardiovascular Health

Background:

• Erectile dysfunction (ED) is a common condition with multifactorial causes.
• Chronic inflammation, potentially linked to infections like latent tuberculosis infection (LTBI), may contribute to ED development via atherosclerosis.
• The prevalence of LTBI in ED patients and its specific role in high-grade ED remain understudied.

Purpose of the Study:

• To determine the frequency of LTBI among patients presenting with erectile dysfunction.
• To investigate the association between LTBI and the severity of erectile dysfunction, specifically high-grade ED.
• To explore LTBI's contribution to high-grade ED development, considering chronic inflammation and atherosclerosis.

Main Methods:

• A cohort of patients with erectile dysfunction underwent comprehensive clinical evaluation, imaging, and laboratory testing.
• Diagnostic tools included scrotal ultrasonography, tuberculin skin test, and QuantiFERON-TB Gold test to assess for LTBI.
• Multivariate analysis was employed to identify independent risk factors associated with high-grade ED.

Main Results:

• The study sample had a mean age of 47.9 years.
• Approximately 30% of patients with ED were found to have LTBI.
• Older age (≥40 years), metabolic syndrome (MS), and LTBI were independently associated with high-grade ED (p < 0.05 for all).

Conclusions:

• The prevalence of LTBI is significantly higher in patients with high-grade ED compared to those with low-grade ED.
• LTBI is identified as an independent risk factor contributing to the development of high-grade ED.
• Older age and metabolic syndrome are also confirmed as significant independent risk factors for high-grade ED.
