Hyperthyroidism in end-stage renal disease.

We report the 2nd patient to have hyperthyroidism while on maintenance hemodialysis. This case is instructive because the diagnosis of hyperthyroidism in uremic patients is difficult due to similar signs and symptoms. This case report describes, for the first time, the unique interaction between hemodialysis and thyrotoxic heart disease. Paroxysmal atrial fibrillation and severe hypotension interfered with all hemodialyses. Only the correction of the hyperthyroid state and withdrawal of all beta-blocking agents allowed resumption of normal hemodialysis. The delayed gastric emptying and hypercalcemia ultimately resolved with return to the euthyroid state and did not recur during 10 months of follow-up.
