Long-term outcome of treatments for Graves disease in the children and adolescent population.

BACKGROUND

Several studies were conducted over the years to find a significant association between non-surgical therapies such as Antithyroid Drug (ATD) Therapy and Radio-iodo therapy (RIT) with Graves' disease (GD) remission and relapse. However, these investigations did not have a specific focus on the age category of children and adolescents. Hence, this Research is performed to assess the association of non-surgical therapy (ATD and RIT) with Graves' disease (GD) remission and relapse in the children and adolescent population.

DESIGN

A systematic review and meta-analysis of observational studies and clinical trials were carried out.

METHODS

A systematic search of PubMed, EMBASE, and SCOPUS from their inception till April 2022 was performed for studies stating an association between ATD therapy and GD remission and relapse in participants 1-17 years old. The random-effects model was used in the meta-analysis to provide a pooled proportion of both primary outcomes. The quality and each study were assessed using the Newcastle Ottawa Scale (NOS).

RESULT

From 6195 studies searched from the databases, only 16 relevant articles remained after a detailed evaluation. These studies, having a total of 2557 patients aged 5-17 years, were involved in the analysis with a pooled estimate showing a significant association of ATD therapy with GD remission (Estimate: 0.400, 95% Confidence interval: 0.265-0.535; I^2 = 98.16%) and with GD relapse (Estimate: 0.359, 95% Confidence interval: 0.257-0.461; I^2 = 98.26%). Subgroup analyses were conducted to assess the remission rate of different therapies suggesting that antithyroid drugs play a significant role in the remission of the patients. All included studies were classified as moderate quality.

CONCLUSION

Following meta-analysis suggested that the ATD used in the analysis is effective in remitting GD in the children and adolescents population. Nevertheless, long-term RIT therapy and thyroidectomy leads to hypothyroidism. Still, large-sample, and high-quality studies targeting ATDs' use in children and adolescents with long-term surveillance of prognosis are needed.
