A prospective study of renal function was undertaken on an unselected group of 8 children with chronic progressive liver disease on whom a renal biopsy was performed subsequently at the time of orthotopic liver transplantation. Two patients had abnormal urinalyses and 2 elevated urinary albumin/creatinine ratios. The remainder had no clinical evidence of renal dysfunction. All had normal serum creatinine concentrations. Glomerular abnormalities were present in all renal biopsies and were of two types: hepatic glomerulosclerosis (n = 5) and minor glomerular abnormalities (n = 3). IgM immunofluorescence was present in all biopsies and IgA in 6. Elevated serum immunoglobulin levels were observed in all patients, with IgM elevation in 6, IgA in 4 and IgG in 6. C3 and/or C4 were reduced in 5 patients and increased circulating immune complexes containing IgM were noted in 4. The clinical significance of these cirrhosis-associated glomerular abnormalities can only be established by long-term follow-up studies after orthotopic liver transplantation.

The effects of oral BCAA supplementation on fasting levels of prolactin and estradiol were retrospectively analyzed in frozen plasma samples of patients with cirrhosis and chronic hepatic encephalopathy, taking part in a 3-month randomized, double-blind trial. Twenty-five patients had received 0.24g of BCAA per kg body weight, 24 had received an equinitrogenous amount of casein, in addition to a diet providing 0.7-1.0 g/kg of protein. Thirty-eight were males, 11 post-menopausal women. Fasting prolactin did not show any change in the BCAA group, where mental state significantly improved. In the casein group plasma prolactin increased by nearly 50% during the 3-month period. Similarly, estradiol concentrations were unchanged during BCAA supplementation, and increased during casein treatment. The analysis of variance demonstrated significant differences between the 2 treatments. Liver function tests and nutritional parameters (albumin, transferrin, urinary creatinine) supported a superiority of BCAA over casein. These data suggest that the favorable effects of BCAA on mental state are not mediated by changes in cerebral neurotransmission, but are due mainly to maintained liver function, possibly related to improved nutrition.

The serum levels of the 7S domain of type IV collagen were measured with a radio-immunoassay in 42 patients with primary biliary cirrhosis (asymptomatic: n = 28; symptomatic: n = 14), 10 patients with chronic active hepatitis, 10 patients with liver cirrhosis and 10 healthy female controls. Serum levels of the 7S domain of type IV collagen were: 4.28 ng/mL (3.88-4.72 ng/mL; mean and range of mean +/- s.d.) in healthy controls; 5.97 ng/mL (5.07-7.02 ng/mL) in patients with chronic active hepatitis; 8.23 ng/mL (6.40-10.58 ng/mL) in patients with liver cirrhosis; and 6.79 ng/mL (4.76-9.67 ng/mL) in patients with primary biliary cirrhosis. Patients with liver cirrhosis and primary biliary cirrhosis had higher levels of serum 7S domain of type IV collagen than healthy controls (P < 0.001, respectively). Serum levels of the 7S domain of type IV collagen in patients with asymptomatic primary biliary cirrhosis, 5.83 ng/mL (4.55-7.48 ng/mL) were significantly lower than those in symptomatic primary biliary cirrhosis, 9.18 ng/mL (6.53-12.91 ng/mL; P < 0.001). Serum levels of the 7S domain of type IV collagen increased significantly along with advancement of the histological stages of primary biliary cirrhosis. Serum levels of the 7S domain of type IV collagen in the paired sera of eight patients with asymptomatic primary biliary cirrhosis (mean interval 30 months, range 12-48 months) showed significant rises during the intervals (P < 0.05), while serum levels of albumin and total bilirubin did not change significantly during these intervals.(ABSTRACT TRUNCATED AT 250 WORDS)

Of the many information obtainable from the urine of diabetic patients, urinary C-peptide (CPR), albumin and anti-diuretic hormone (ADH) were representatively described using my clinical and experimental data. C-peptide excretion in 24h collection of urine is a good estimate of insulin secretion from the pancreas and thus low in IDDM patients and even in NIDDM patients at a later stage, but high in pathological conditions including Graves' disease, obesity, liver cirrhosis and Cushing's syndrome. Urinary albumin excretion in small amounts (microalbuminuria) is usually observed in diabetic patients who have been under a poor control state of diabetic hyperglycemia for over 5 years and provides a good tool for monitoring early diabetic nephropathy. The grade of microalbuminuria (30-300 mg/day) is positively correlated with the HbA1 level in diabetic patients, showing that microalbuminuria is reversible along with an improvement of diabetic control at least in an early phase of diabetic nephropathy. As the albumin level measured in a spot urine sample correlates well with the value in the 24h collection of urine, the albumin measurement is conveniently feasible with a spot urine sample at every patient's visit. The amount of ADH excreted in urine is 7-10% of that secreted from the posterior pituitary. The excretion of ADH in a day was in the urine of diabetic patients positively correlated with HbA1, urinary osmolarity and concentration of sodium in urine, although the pathological meaning of the observed ADH hypersecretion in the development of diabetic complications is currently unknown.

We conducted a prospective study of renal histology and function in 18 consecutive nonalcoholic patients who underwent orthotopic liver transplantation (OLT). Despite well-preserved renal function, all patients had abnormal renal biopsies. Four patterns of glomerular injury were identified: minor glomerular abnormalities (eight patients), hepatic glomerulosclerosis (seven), membranoproliferative glomerulonephritis (one), and IgA nephropathy (one). In one patient there was insufficient tissue to allow classification. There was a trend toward lower plasma bilirubin and higher plasma albumin in patients with minor glomerular abnormalities than in the group of patients with more severe forms of glomerular injury (29 v 82 mumol/L, 35.5 v 30 g/L; P = 0.1, 0.1 greater than P greater than 0.05, respectively). Glomerular changes persisted in the three patients who died within 7 weeks post-OLT. IgM immunofluorescence was present in all biopsies and IgA in 11. IgM-containing circulating immune complexes occurred in five patients, suggesting a pathogenic role for IgM immune complex deposition. The significance of cirrhosis-associated glomerular abnormalities is not yet known. They may contribute to the hepatorenal syndrome and the renal dysfunction that occurs in up to 94% of patients post-OLT.

The medical treatment of ascites in cirrhosis is based on sodium restriction and the administration of diuretics. Because the natriuretic potency of spironolactone is greater than that of loop diuretics (i.e., furosemide) in patients with marked sodium retention, spironolactone is the basic drug for the treatment of ascites. The simultaneous administration of spironolactone and furosemide increases the natriuretic effect of each drug and diminishes their effects on potassium metabolism. Recent studies indicate that large-volume paracentesis associated with intravenous albumin infusion is more effective than diuretic therapy in eliminating the ascitic fluid; is associated with a lower incidence of complications (hepatic encephalopathy, renal impairment, and hyponatremia); and considerably reduces the duration of hospital stay. Therapeutic paracentesis associated with intravenous albumin infusion is therefore the treatment of choice for cirrhotic patients with tense ascites. The mobilization of the ascitic fluid by paracentesis without plasma volume expansion is constantly associated with a deterioration of effective circulating blood volume and may induce renal impairment and severe hyponatremia. Dextran 70 and polygeline appear as effective as albumin in preventing these abnormalities. Cirrhotic patients treated with paracentesis require the administration of diuretics to avoid reaccumulation of ascites. Peritoneovenous shunt, a prosthesis capable to correct most abnormalities involved in the accumulation of fluid in the abdominal cavity, is an effective treatment of ascites in cirrhosis. It is especially indicated in patients who do not respond to diuretics and develop repeated episodes of ascites despite adequate treatment. The use of peritoneovenous shunting is limited by the high incidence of complications induced by the procedure, however. In addition, approximately 40% of patients develop an obstruction of the prosthesis within the first postoperative year.

The concentrations of human plasma albumin (HPA) and alpha-1-acid glycoprotein (AAG) were measured in the serum obtained from 84 healthy subjects, 56 umbilical cords, 41 patients with renal failure, 65 patients maintained on chronic hemodialysis and 46 patients with liver cirrhosis. Severity of liver dysfunction was assessed with the use of Pugh et al. [1973] classification. Of the cirrhotic patients, 12, 22 and 12 patients were classified as mild, moderate and severe liver dysfunction, respectively. The coefficient of variation of AAG was greater than HPA in all groups of subjects, and the variability of HPA and AAG is increased in patients compared to healthy subjects. As the liver dysfunction progresses, HPA concentration decreases whereas, the average AAG concentration is not changed in mild, moderate and severe liver dysfunction. The coefficients of variation for HPA and AAG in moderate and severe liver disease is over twice those for healthy subjects. The concentration of HPA is normally distributed in all groups of subjects, with the exception of the cord serum. The frequency distribution of AAG was normal in healthy subjects whereas, it was asymmetric, being positively skewed, in newborn, in renal and liver patients. The wide interindividual variability and the not-normal frequency distribution of AAG in liver or renal patients make its mean of little value in defining a group. Neither HPA nor AAG correlated with the clearance of creatinine in renal patients. In liver disease, HPA and AAG did not correlate with GPT and GOT activities, prothrombinic activity and bilirubin concentration. HPA did not correlate with AAG in any group.

We have analyzed the indications and results of shunt operation versus orthotopic liver transplantation (OLT) in 22 patients with Budd-Chiari syndrome (BCS). The underlying cause of the syndrome was similar between the two groups and was related to myeloproliferative disorders or the use of birth control pills in 18 of 22 patients. The results of biopsies of the liver showed centrilobular congestion and necrosis in all candidates who underwent shunting and the presence of fibrosis and cirrhosis in the OLT candidates. The indications for shunts included symptoms related to portal hypertension only and well-preserved synthetic hepatic function. Ten patients were treated with 12 shunt procedures, including mesoatrial (eight patients) and side to side portacaval shunt (four patients). Significant complications after shunt procedure included fulminant (one of ten patients) and progressive (one of ten patients) hepatic failure requiring urgent OLT; one death occurred because of pulmonary sepsis. Indications for OLT were signs of end stage liver expressed by severe portal hypertension and variceal bleeding (four of 14 patients), progressive encephalopathy (seven of 14 patients) and poor synthetic function (bilirubin greater than 3 milligrams per deciliter in eight of 14 patients and albumin less than 3.0 grams per liter, or both, in ten of 14 patients). Fourteen patients were treated with 16 OLT, three patients had retransplantation for primary nonfunction graft (two of 14 patients) or chronic rejection (one of 14 patients). There were two early deaths in the group. With a follow-up period between two months to five years, 12 of 14 patients undergoing OLT are alive, fully functional and have normal liver function tests. Seven of ten patients who had shunts are alive, six are able to maintain normal activity and one has progressive end stage hepatic disease and is not a candidate for OLT. However, the hepatic function continues progressively to be abnormal. Various options are available for the treatment of the syndrome. Portosystemic decompression is effective and should be considered at the early stage of the disease, prior to the development of significant hepatic failure. However, few of the patients will continue to have slow, but progressive hepatic failure and may require OLT. The only effective treatment for end stage hepatic disease secondary to the BCS is OLT.

We have investigated the influence of variation of the concentrations of serum albumin and immunoglobulins on serum fructosamine concentration in 33 patients with nephrotic syndrome, and 18 patients with cirrhosis of the liver. Protein alterations were evident in these patients and they were compared with 109 normal subjects, 43 patients with type II diabetes mellitus and nine diabetic patients with nephrotic syndrome. The mean serum fructosamine concentration in diabetic patients (2.76 +/- 0.53 mmol/L) was significantly increased (P less than 0.001) by comparison with normal subjects (1.93 +/- 0.20 mmol/L) and the other patients studied. Patients with diabetic nephropathy had higher (P less than 0.01) serum fructosamine concentrations (2.23 +/- 0.54 mmol/L) than non-diabetic patients with the nephrotic syndrome (1.57 +/- 0.37 mmol/L) but remained with the normal range. Positive correlations were observed between fructosamine and immunoglobulins G and M in nephrotic and cirrhotic patients. Serum immunoglobulin A was also directly correlated with serum fructosamine in patients with cirrhosis of the liver. An inverse correlation between albumin and fructosamine in serum of patients with cirrhosis of the liver was also noted. We conclude that the fructosamine assay is not useful in the assessment of glycemic control in patients with cirrhosis of the liver, nephrotic syndrome or in any other clinical situation in which protein metabolism is altered.

It has been reported that hepatoma (HCC) cells produce abnormal proteins such as erytropietin, fibrinogen, prothrombin, and, recently, antithrombin III (AT III). In a preliminary report, we reported increased AT III levels in patients bearing HCC independent of their clinical liver status. The present study was performed to assess antithrombin III levels and other serological data present in patients with cirrhosis and in patients with cirrhosis and clinical findings of neoplastic disease. In 70 well-matched patients (47 with cirrhosis and 23 with cirrhosis and proven HCC) serum total cholesterol, albumin, prothrombin, alkaline phosphatase, AFP, aminotransferases, and AT III were determined. Together with AFP and alkaline phosphatase, patients with HCC had higher values of AT III (88 +/- 7%) and total cholesterol (184 +/- 17 mg/100 ml), as compared with cirrhotic patients (AT III 56 +/- 3.6%; total cholesterol 113 +/- 5 mg/100 ml) (P less than 0.001). No difference was observed between these two groups for albumin, prothrombin, and aminotransferases. In HCC patients, AT III levels were related to the total cholesterol level (R2 = 0.317), whereas in the cirrhotic patients it correlated with the prothrombin level (R2 = 0.274). These data suggest that in HCC patients a greater rate of synthesis of AT III occurs, whereas in cirrhotic patients lower levels of AT III occur due to impaired synthesis or increased catabolism of the protein. The serial determination of AT III in cirrhotic patients as a means of detecting neoplastic transformation is suggested.
