Serum apelin levels in patients with thyroid dysfunction.

Area of Science:

• Endocrinology
• Metabolic Research
• Molecular Biology

Background:

• Adipocytes are crucial endocrine cells producing adipocytokines, which regulate various physiological functions.
• Apelin is an important adipocytokine involved in metabolic and hormonal regulation.
• Thyroid dysfunction is associated with alterations in metabolism, body weight, and adipose tissue function.

Purpose of the Study:

• To investigate serum apelin levels in individuals with different thyroid hormone states.
• To explore the relationship between apelin and thyroid dysfunction.

Main Methods:

• Cross-sectional study involving patients with thyrotoxicosis, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, and healthy controls.
• Measurement of serum apelin, free T3 (FT3), free T4 (FT4), and TSH levels.
• Recording of body mass index (BMI).

Main Results:

• No statistically significant differences in demographic characteristics (age, BMI) were observed between the groups.
• Mean serum apelin levels showed a trend towards being higher in thyrotoxicosis (4.6±1.9 ng/ml) and hypothyroidism (4.8±2.5 ng/ml) groups compared to the control group (3.4±1.4 ng/ml).
• Despite observed variations, no statistically significant differences in mean serum apelin levels were found across all study groups (P>0.05).

Conclusions:

• Serum apelin levels do not significantly differ between individuals with various thyroid dysfunction states and healthy controls.
• Further research may be needed to elucidate the precise role of apelin in thyroid pathophysiology.
