An Interesting Case of Hypothyroidism Associated Acute Kidney Injury

Muscle involvement is common in hypothyroidism. However, hypothyroidism as a causal factor for severe rhabdomyolysis and acute kidney injury (AKI) is rarely reported. We report a case of a 56-year-old Arab male who presented with unexplained acute worsening of chronic kidney disease. The patient was detected to have hypothyroidism and rhabdomyolysis on laboratory investigations. However, thyroxine replacement led to partial recovery of renal function. CPK also improved with vigorous hydration and thyroxine replacement. Although this is a rare association, in the absence of other causes of rhabdomyolysis, hypothyroidism should be suspected in patients presenting with AKI and high creatinine phospho-kinase.
