68-year-old woman with hepatitis C and abnormal kidney function.

A 68-year-old woman with a history of hepatitis C (contracted from a blood transfusion in 1974) complicated by cirrhosis and portal hypertension came to the Mayo Clinic in Rochester, Minn, for evaluation for possible liver transplantation. Her symptomatic ascites had been treated initially with furosemide and spironolactone, but this treatment regimen was limited because of an increase in her creatinine level. During evaluation, hypertension (an average blood pressure of 180/90 mm Hg on 6-hour ambulatory monitoring) and abnormal renal function were noted. She was referred to our institution for further evaluation of her blood pressure and abnormal urinalysis results.
