Multi-element analysis of metals in human pathological and unchanged thyroid glands - pilot study

Area of Science:

• Biochemistry
• Metallomics
• Endocrinology

Background:

• Elemental imbalances in thyroid tissue disrupt homeostasis, potentially leading to severe health issues and tumors.
• Metallomics typically analyzes serum, but thyroid tissue offers more direct, credible insights into elemental composition.
• Thyroid disorders encompass a range of conditions including goiters, thyroiditis, adenomas, and carcinomas.

Purpose of the Study:

• To investigate elemental composition in thyroid tissue and serum from patients with various thyroid disorders.
• To explore correlations between elemental concentrations, inflammation, glycation, and peroxidation markers.
• To establish a foundation for understanding thyroid disease pathomechanisms and risk minimization.

Main Methods:

• Analysis of elemental content (Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Zn) in thyroid tissue and serum using Inductively Coupled Plasma - Optical Emission Spectrometers (ICP-OES).
• Biochemical assessment of inflammation, glycation, and peroxidation markers (malondialdehyde, pentosidine, etc.) in patient sera.
• Comparative analysis of elemental and biochemical data across different thyroid disorder groups.

Main Results:

• Identified statistically significant correlations: Ca-Mg and Cu-Zn in control tissues (p < 0.05), and Cr-Mn in pathological tissues (p < 0.05).
• Observed potential tendencies for altered concentrations of certain elements and markers in specific patient groups.
• Highlighted preliminary relationships between elemental profiles and thyroid disease states.

Conclusions:

• Elemental homeostasis in thyroid tissue is crucial for metabolic health.
• Thyroid tissue analysis provides valuable data for understanding disease mechanisms.
• This pilot study lays the groundwork for future research into thyroid disease etiology and prevention.
