Association of 25(OH)D status with calcium metabolism, inflammation, and thyroid autoimmunity in patients with type 2 diabetes mellitus
Clinical Report: Relationship Between Serum 25-Hydroxyvitamin D Levels and Calcium Regulation, Inflammatory Responses, and Thyroid Autoimmune Activity in Individuals with Type 2 Diabetes Mellitus
Overview
This study reveals a high prevalence of 25-hydroxyvitamin D deficiency in patients with type 2 diabetes mellitus (T2DM), significantly correlating with altered calcium metabolism, increased inflammatory markers, and thyroid autoimmunity. The findings suggest complex interactions between vitamin D status and thyroid autoantibodies.
Background
Vitamin D deficiency is common in individuals with T2DM and may exacerbate metabolic and immune dysfunction. Understanding the relationship between vitamin D levels and various physiological parameters is crucial for managing T2DM and associated conditions, such as autoimmune thyroid disease. This study aims to clarify these associations and their clinical implications.
Data Highlights
Parameter
Findings
Prevalence of 25(OH)D deficiency
83.7% of patients
Correlation with PTH
Higher 25(OH)D levels correlated with lower PTH (P = 0.010)
Calcium levels
Higher calcium associated with higher 25(OH)D (P<0.001)
hsCRP levels
Peaked in moderate deficiency group (2.66 mg/L, P<0.001)
T3 and fT3 levels
Peaked in insufficiency group, lowest in severe deficiency (P<0.05)
TGAb and TPOAb
TGAb positivity associated with higher 25(OH)D levels (P = 0.008), TPOAb with lower levels (P<0.001)
Key Findings
83.7% of T2DM patients exhibited 25(OH)D deficiency.
Higher 25(OH)D levels were linked to lower parathyroid hormone (PTH) levels.
Calcium levels increased with higher 25(OH)D concentrations.
hsCRP levels were highest in the moderate deficiency group.
T3 and fT3 levels were lowest in patients with severe vitamin D deficiency.
Distinct associations were observed between thyroid autoantibodies and 25(OH)D levels.
Clinical Implications
Clinicians should consider routine assessment of vitamin D levels in patients with T2DM, as deficiency may contribute to metabolic dysregulation and autoimmune activity. Addressing vitamin D deficiency could potentially improve calcium metabolism and reduce inflammatory responses in this population.
Conclusion
The study underscores the importance of monitoring and managing vitamin D levels in patients with T2DM to mitigate associated metabolic and autoimmune complications.
