ABSTRACT

Introduction

Thyrotoxicosis is one of the most common endocrine disorders seen in clinical practice. This study aims to determine the etiologies and treatment modalities of thyrotoxicosis in Africa.

Areas covered

The study design is a systematic review with a meta-analysis. Medical databases and the gray literature were systematically searched following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies done in Africa on the etiology and treatment of thyrotoxicosis were selected.

Expert opinion

In Africa, it is still believed that autoimmune diseases, generally, are not as common as what is seen in the western world. The frequency of Graves’ disease is reportedly lower in Africa. The treatment of thyrotoxicosis depends on the cause. Therefore, it is of substantial importance to establish the etiology following the diagnosis of the clinical syndrome.

Article highlights

  • Graves’ disease is the most common cause of thyrotoxicosis in Africa

  • The second most common cause of thyrotoxicosis in Africa is toxic multinodular goiter

  • Thionamides are the most common treatment modality for thyrotoxicosis in Africa

  • About one in five relapses on thionamides treatment following remission.

  • Thyroidectomy and radioablative therapy are the second and third most common modalities for treating thyrotoxicosis in Africa, respectively.
