Levothyroxine treatment in pediatric benign thyroid nodules

Area of Science:

• Pediatric Endocrinology
• Thyroidology
• Clinical Therapeutics

Background:

• Benign thyroid nodules are common in children and adolescents.
• The efficacy of levothyroxine therapy for these nodules is not well-established.
• Understanding treatment effects is crucial for pediatric thyroid management.

Purpose of the Study:

• To evaluate the effectiveness of levothyroxine therapy in pediatric patients with benign thyroid nodules.
• To assess the impact of treatment on nodule size, palpability, and associated symptoms.

Main Methods:

• Retrospective analysis of 78 euthyroid children and adolescents with benign thyroid nodules.
• Comparison between a levothyroxine-treated group (n=36) and a non-treated group (n=42).
• Follow-up over 2.4 ± 1.3 years, monitoring clinical, laboratory, and sonographic features.

Main Results:

• Levothyroxine treatment resulted in a significant reduction in nodule diameter (p=0.039).
• Nontreated patients showed an increase in nodule size (p=0.024).
• 30.6% of treated patients experienced >50% nodule size reduction; palpable nodules decreased significantly (p<0.001).

Conclusions:

• Levothyroxine therapy is effective in reducing the size of benign thyroid nodules in pediatric patients.
• Treatment correlates with decreased nodule size and palpability.
• Further research may confirm levothyroxine as a beneficial treatment option for pediatric benign thyroid nodules.
