An unusual case of “renal failure”

摘要

Myopathy is common in hypothyroidism, but a very high creatinine kinase (CK) level in the range commonly seen with inflammatory myopathy is rare. Reversible elevation of creatinine is known to occur in hypothyroidism due to a decrease in the glomerular filtration rate, but it can also occur rarely due to enhanced creatinine production. We present a case of severe hypothyroidism with massively elevated CK levels and high creatinine levels, both of which reversed on treatment of hypothyroidism.Keywords: Creatinine, creatinine kinase, hypothyroidism
