The Effect of Hydroxychloroquine Treatment in Hashimoto's Thyroiditis

Overview[ - collapse ][ - ]

Purpose Hashimoto's thyroiditis is an autoimmune thyroid disease, which induced chronic inflammation of thyroid gland and destroys thyroid tissue. Hydroxychloroquine is used as disease modifying anti-rheumatic drug (DMARD) for treatment of several autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis(RA) for more than one century. The purpose of this study is to evaluate whether hydroxychloroquine is effective in treatment of Hashimoto's thyroiditis.

Current Primary Outcome Measures
  • Anti-TPO antibody [Time Frame: 6th month after medical treatment] [Designated as safety issue: No]Check anti-TPO antibody 6 months after medical treatment as inflammatory marker

Official TitleThe Effect of Hydroxychloroquine Treatment in Hashimoto's Thyroiditis
Brief Summary
Hashimoto's thyroiditis is an autoimmune thyroid disease, which induced chronic inflammation
of thyroid gland and destroys thyroid tissue.

Hydroxychloroquine is used as disease modifying anti-rheumatic drug (DMARD) for treatment of
several autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid
arthritis(RA) for more than one century.

The purpose of this study is to evaluate whether hydroxychloroquine is effective in
treatment of Hashimoto's thyroiditis.
Detailed Description
Hashimoto's thyroiditis is an autoimmune thyroid disease, and when the disease progresses,
thyroid function finally declined to hypothyroidism.

There was no medical treatment recommended for patients with Hashimoto's thyroiditis, but
currently at euthyroid state. Levothyroxine replacement therapy starts if patients become
hypothyroid state.

Hashimoto's thyroiditis is a T-cell mediated autoimmune thyroid disease. The major
auto-antigens include thyroid peroxidase (TPO) and thyroglobulin. Anti-TPO antibodies induce
antibody-dependent cell-mediated cytotoxicity (ADCC) and cause destruction of thyroid
tissues.

Antimalarial agents like hydroxychloroquine have several pharmacologic effects which may be
involved in the treatment of rheumatic diseases, but the role of each is not known. These
include interaction with sulphydryl groups, interference with enzyme activity (including
phospholipase, nicotinamide adenine dinucleotide hydrogen-cytochrome C reductase,
cholinesterase, proteases and hydrolases), DNA binding, stabilisation of lysosome membranes,
inhibition of prostaglandin formation, inhibition of polymorphonuclear cell chemotaxis and
phagocytosis.

This study is to investigate the treatment effect of hydroxychloroquine on autoantibodies
and disease progression of Hashimoto's thyroiditis.
