The plasma protein binding of disopyramide (D) was determined in seven patients with
cirrhosis
, six with nephrotic syndrome, and seven healthy subjects. Plasma samples containing concentrations of 0.2 to 12.0 micrograms/ml were ultrafiltered and the free fractions were measured with fluorescence polarization immunoassay. The mean free fractions at D concentrations ranging from 1 to 6 micrograms/ml were significantly (P less than 0.01) greater in patients with
cirrhosis
than in healthy subjects. No difference was observed between patients with nephrotic syndrome and healthy subjects. The free fraction at
D 3
micrograms/ml correlated better with alpha 1-acid glycoprotein (r = -0.77) than with albumin (r = -0.46). Patients with
cirrhosis
had significantly (P less than 0.01) lower capacity constants as compared with the other two study groups. There was a significant (P less than 0.01) correlation between capacity constant and alpha 1-acid glycoprotein (r = 0.71). Our results suggest that the D therapeutic range measured as the total plasma concentration in
cirrhosis
, but not in nephrosis, should be approximately 50% lower than previously believed.

Various autonomic dysfunctions (AD) are known to occur in
cirrhosis of the liver
. The haemodynamic abnormalities of
cirrhosis
have been correlated with AD and have prognostic implications. The relevance of AD in extrahepatic portal vein obstruction (EHPVO) is not well established. We evaluated AD and cardiac indices in 30 patients, 19 male and 11 female and compared the results with those of 10 controls. The mean age of the patients and controls was 23.77 +/- 1.33 and 20.5 +/- 2.51 years, respectively. Five standard autonomic function tests were done in all the patients. Cardiac output (CO) was measured by echocardiography. Anthropometric measurements were done to determine the cardiac index (CI = Cardiac output/Body surface area) and indicized peripheral vascular resistance (iPVR) was calculated using the formula: mean arterial pressure (MAP) x 80/CI. Each autonomic function test was given a score and the results were interpreted as normal, early or definite, according to the score. AD was recorded as normal in 5, early in 11 and definite in 14 patients. None of the controls had any abnormality in autonomic function. There was a significant difference in the baseline heart rate of controls and patients (76 +/- 2.55 v. 98.9 +/- 2.96 beats/min). There was no difference in the MAP (92.65 +/- 1.71 v. 81.7 +/- 1.99 mmHg), CI (2.99 +/- 0.15 v. 3.23 +/- 0.08), iPVR (2533.59 +/- 124 v. 2176 + 104). CI, iPVR and MAP were also calculated separately in patients in the normal (N), early (E) and definite (D) AD groups. Their respective values were as follows CI: N 3.44 +/- 0.19, E 3.44 +/- 0.19,
D 3
.23 +/- 0.6; iPVR: N 2150 +/- 75.4, E 2140 +/- 180, D 2372 +/- 142; MAP: N 86 +/- 3.01, E 85.8 +/- 3.59, D 90.79 +/- 3.09. Results are expressed as mean +/- SE. Unlike in cirrhotics, cardiovascular haemodynamics are not altered in patients with EHPVO, even in the presence of AD.
