Abstract
Distal renal tubular acidosis (dRTA) may rarely occur in the course of autoimmune diseases. We present a patient who was followed up with Graves' disease and vitiligo and who was diagnosed with dRTA upon detection of hypopotasemia. A 9.2-year-old girl presented with complaints of sweating, palpitations, and hand tremors. The patient had vitiligo on examination and was diagnosed with Graves' disease per clinical and laboratory findings. The patient, who received methimazole and was followed up as a euthyroid, was found to have hypokalemia in biochemical examinations performed at the age of 13 years. While investigating the etiology of hypokalemia, the patient was diagnosed with dRTA. Since she had two autoimmune pathologies, it was thought that the dRTA might be of autoimmune origin. Checking serum potassium levels in the follow-up of patients with Graves' disease may allow early diagnosis and treatment of accompanying dRTA.
