Venous insufficiency: Differences in the content of trace elements. A preliminary report

Area of Science:

• Biochemistry
• Vascular Biology
• Trace Element Analysis

Background:

• Venous insufficiency is a prevalent clinical issue with unknown molecular causes.
• Risk factors include genetics, hormones, and prolonged standing, but trace element imbalance may also contribute.
• This study investigates trace element differences in healthy versus pathological veins.

Purpose of the Study:

• To identify differences in trace element levels between healthy and insufficient veins.
• To explore the potential role of trace elements in the molecular mechanisms of venous insufficiency.
• To provide data that may aid in developing improved treatment strategies.

Main Methods:

• Trace element content was quantified in varicose and normal vein walls.
• Inductively coupled plasma-optical emission spectrometry (ICP-OES) was employed after sample mineralization.
• Statistical analyses, including Mann-Whitney U test and Friedman ANOVA, were used for comparison.

Main Results:

• Statistically significant higher magnesium (Mg) ion levels were observed in varicose veins compared to controls (p = 0.0067).
• Differences approaching statistical significance were noted for calcium (Ca), manganese (Mn), and silicon (Si) ion levels.
• These findings indicate distinct trace element profiles in venous insufficiency.

Conclusions:

• Elevated Mg, Mn, and potentially Cu ions may be linked to oxidative stress and free radical neutralization in chronic venous insufficiency via superoxide dismutase (SOD) activity.
• The results align with existing literature and suggest a role for trace elements in venous pathology.
• Further research is warranted to confirm these preliminary findings and elucidate their clinical implications.
