Abstract

BACKGROUND:

Varicocele, inguinal hernia, and clinical manifestations related to chronic venous disorders are often associated, and collagen metabolism together with metalloproteinases (MMPs) alterations may be implicated. The aim of this study was to analyze the relationship between these factors.

METHODS:

We evaluated tissue and plasma samples from patients with varicocele, inguinal hernia, and great saphenous vein reflux, who underwent surgical treatment for their conditions. We then analyzed and correlated these findings with MMP levels.

RESULTS:

Significantly higher levels of MMP-1, -2, -12, and -13 were found in patients with inguinal hernia. MMP-9 levels were higher in patients with at least two of the conditions indicated.

CONCLUSION:

MMP-9 seems to be the common thread in various clinical conditions and is related to a more general and progressive disorder of collagen metabolism.
