This study is to determine whether a compound, nitric oxide, made within the body, is the factor responsible for the changes in blood pressure and renal (kidney) functions that may occur during the course of cirrhosis. Patients with cirrhosis (liver scarring which causes poor liver function) will be eligible to participate. A group of healthy subjects will also be studied to compare the effects of the treatment to patients with cirrhosis and to confirm safety. A total number of 30 patients with cirrhosis and 10 healthy subjects will be enrolled in the study.

Study Design: | Treatment, Open Label |
Upon admission, the patients will be physically examined and started on a special diet that will continue throughout the study. During the first four days of the study, the weight, heart rate and blood pressure of the patients will be measured every morning and 24-hour urine will be collected. On day 5, intravenous lines will be inserted in the patient's arms. One line will be used to draw blood samples and the other line will be used to infuse medications. Blood samples will be taken to measure liver and kidney function, nitric oxide, and other hormones that participate in the regulation of body fluids and blood pressure. Inulin and paraaminohippurate infusions (substances used routinely in the study of kidney function) will be started and blood and urine samples will then be taken at periodic intervals. Ninety minutes after the initiation of inulin and PAH infusions, L-NMMA (an investigational drug expected to increase the blood pressure and improve the kidney functions) will be infused. Blood and urine samples will be collected every 30 minutes. These procedures will take 4 hours. A total amount of about 10 tablespoons of blood will be drawn during the study. The patients will be discharged from the GCRC the next morning and restarted on their regular medications.
