[Polyneuropathy during treatment with carbimazole].

Area of Science:

• Neurology
• Endocrinology
• Pathology

Background:

• Thyrotoxicosis is a condition of excess thyroid hormones.
• Carbimazole is a common antithyroid medication used to treat thyrotoxicosis.

Observation:

• A patient undergoing carbimazole treatment for thyrotoxicosis developed polyneuropathy.
• Neurological examination revealed symptoms consistent with nerve damage.

Findings:

• Electrophysiological studies indicated a mixed axonal and demyelinative neuropathy.
• A neuromuscular biopsy confirmed nerve damage and revealed associated microvasculitis.

Implications:

• This case highlights a potential adverse effect of carbimazole.
• The findings suggest a link between carbimazole, polyneuropathy, and microvasculitis.
• Further research is needed to understand the underlying physiopathological mechanisms.
