Treatment of severe hypothyroidism in a patient with progressive renal failure leads to significant improvement of renal function.
The case of a 41-year-old patient with end-stage renal failure and diabetes mellitus Type 1 who was being prepared for renal replacement therapy is described. After severe hypothyroidism was diagnosed, thyroid hormone substitution therapy was started. Subsequently, a substantial decline in serum creatinine was observed. Creatinine clearance rose from 19 to 40 ml/min and renal replacement therapy was no longer imminent. Several studies have described the pathophysiology of diminished renal function in hypothyroidism. Few studies or case reports have shown amelioration of end-stage renal failure as seen in our patient. The etiology is presumed to be multifactorial, in which hemodynamic effects and a direct effect of thyroid hormone on the kidney play an important role. Diagnosing signs of hypothyroidism and therapy with thyroid hormone in progressive renal failure could be very important in delaying the need for renal replacement therapy.
