Twenty patients with bilharzial periportal fibrosis (group I); 20 patients with post hepatitic cirrhosis (group II) and 20 normal controls were chosen to study the correlation between the serum level of human growth hormone (GH) and Somatomedin-C (Sm-C); and the anthropometric measurements; liver function tests and various haematological parameters. Group I showed no statistically significant difference in the mean values of serum GH before and after insulin induced hypoglycemia. The basal serum level of Sm-C showed a statistically significant decrease and highly significant decrease after insulin test. A statistically significant positive correlation was evident between the individual values of serum level of GH and Sm-C and the anthropometric measurements, haematological values and liver function tests (r = 0.41). The mean serum level of GH in group 2, showed statistically significant increase before and after insulin test. The mean serum level of Sm-C showed a statistically significant decrease before and after insulin test. A statistically significant negative correlation was found between the individual values of the serum level of GH and Sm-C and the anthropometric measurements, haematological values and liver function tests (r = 0.16).

Alcohol-like liver disease may be observed in patients with obesity or non insulin-dependent diabetes, or after treatment with such antianginal drugs as amiodarone and perhexiline maleate. In such cases cirrhosis is associated, at histology, with foci of acidophilic necroris, Mallory's bodies and inflammatory neutrophilic infiltrates. Alcohol-like liver disease is rare. It affects mostly women in their fifties and usually is clinically latent. Abnormalities of liver function tests mainly consist of increased serum aminotransferase levels. Complications of portal hypertension are uncommon. The pathogenesis of the disease remains purely hypothetical. In practice, in the absence of antianginal therapy the finding of cirrhosis in an obese and/or diabetic patient should prompt a search for excessive alcohol consumption before ascribing the cirrhosis to obesity and/or diabetes.

In order to investigate the objective index of the type of differentiation of symptoms and signs between chronic hepatitis and cirrhosis, the levels of serum Tes, ALD, HCT, INS, GR, gastrin, T3, T4, TSH were tested in the chronic hepatitis and cirrhosis of 27 cases of sthenia-syndrome and 61 cases of asthenia-syndrome. Meanwhile, 30 cases of healthy people were taken as the control. The results indicated that the levels of serum Tes, T3, T4, gastrin in the group of asthenia-syndrome (P less than 0.01, P less than 0.05). The levels of serum T4 and gastrin were increased in the group of sthenia-syndrome than in the groups of asthenia-syndrome and control (P less than 0.01). The levels of serum ALT, HCT, INS, and GR were significantly different between the group of asthenia-syndrome and that of sthenia-syndrome. This suggests that clinic symptoms were concerned with the level of serum endocrine on chronic hepatitis and cirrhosis, such as the function of genital, thyroid, adrenal gland and pancrease. The observation of the levels of serum Tes, T3, T4, ALT, INS, GR and gastrin may be an objective index to differentiate the chronic hepatitis and cirrhosis.

Hepatic insulin extraction is difficult to measure in humans; as a result, the interrelationship between defective insulin secretion and insulin insensitivity in the pathogenesis of glucose intolerance in cirrhosis remains unclear. To reassess this we used recombinant human C-peptide to measure C-peptide clearance in cirrhotic patients and controls and thus derive C-peptide and insulin secretion rates after a 75-gm oral glucose load and during a 10 mmol/L hyperglycemic clamp. Cirrhotic patients were confirmed as insulin-insensitive during a euglycemic clamp (glucose requirement: 4.1 +/- 0.1 mg/kg/min vs. 8.1 +/- 0.5 mg/kg/min; p less than 0.001), which also demonstrated a low insulin metabolic clearance rate (p less than 0.001). Although intolerant after oral glucose, the cirrhotic patients had glucose requirements identical to those of controls during the hyperglycemic clamp (cirrhotic patients: 6.1 +/- 1.0 mg/kg/min; controls: 6.3 +/- 0.7 mg/kg/min), suggesting normal intravenous glucose tolerance. C-peptide MCR was identical in cirrhotic patients (2.93 +/- 0.16 ml/min/kg) and controls (2.96 +/- 0.24 ml/min/kg). Insulin secretion was higher in cirrhotic patients, both fasting (2.13 +/- 0.26 U/hr vs. 1.09 +/- 0.10 U/hr; p less than 0.001) and from min 30 to 90 of the hyperglycemic clamp (5.22 +/- 0.70 U/hr vs. 2.85 +/- 0.22 U/hr; p less than 0.001). However, with oral glucose the rise in serum C-peptide concentration was relatively delayed, and the insulin secretion index (secretion/area under 3-hr glucose curve) was not elevated. Hepatic insulin extraction was reduced both in fasting and during the hyperglycemic clamp (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Glucose intolerance often occurs in liver cirrhosis; therefore a long-term control of plasma glucose levels appears to be important. For this purpose glycated hemoglobin A (HbA1c) determination is proposed as a suitable method, while no data are available on fructosamine test. In 98 cirrhotic patients serum fructosamine and HbA1c levels were compared with those of normal controls and among cirrhotic patients grouped in non glucose-intolerant and with non insulin-dependent (NIDDM) or insulin-dependent diabetes mellitus (IDDM). The mean HbA1c values of cirrhotic patients with normal glycemic control were significantly lower than normal, and only a few IDDM and NIDDM cirrhotic patients showed high values of HbA1c, indicating that HbA1c is often underestimated in these patients. On the contrary, serum fructosamine levels were on the average higher than normal in nondiabetic patients, but they were significantly higher in IDDM and NIDDM patients than in nondiabetics, and the 72% of NIDDM and 85% of IDDM patients had fructosamine levels higher than the upper normal value. In conclusion, in diabetic patients with liver cirrhosis fructosamine seems to be a more suitable test than HbA1c for monitoring blood glucose levels.

Sex hormone binding globulin (SHBG) is a glycoprotein possessing high affinity binding for 17 beta-hydroxysteriod hormones such as testosterone and oestradiol. It is probably synthesized in the liver, plasma concentrations being regulated by, amongst other things, androgen/oestrogen balance, thyroid hormones, insulin and dietary factors, it is involved in transport of sex steroids in plasma and its concentration is a major factor regulating their distribution between the protein-bound and free states. Its detailed role in the delivery of hormones to target tissues is not yet clear. Plasma SHBG concentrations are affected by a number of different diseases, high values being found in hyperthyroidism, hypogonadism, androgen insensitivity and hepatic cirrhosis in men. Low concentrations are found in myxoedema, hyperprolactinaemia and syndromes of excessive androgen activity. Concentrations are also affected by drugs such as androgens, oestrogens, thyroid hormones and anti-convulsants. Measurement of SHBG is useful in the evaluation of mild disorders of androgen metabolism and enables identification of those women with hirsutism who are more likely to respond to oestrogen therapy. Testosterone:SHBG ratios correlate well with both measured and calculated values of free testosterone and help to discriminate subjects with excessive androgen activity from normal individuals.

Polyamines have been known to play an important role in hepatic regeneration. In the present study, we measured the amount of urinary polyamine excretion in various liver diseases using a simple enzymatic method. Urinary polyamine excretion was elevated above the normal range in 21 out of 47 cases with fulminant hepatic failure, acute hepatitis, chronic active hepatitis, and liver cirrhosis. No change, however, was observed in 11 patients with chronic inactive hepatitis. In fulminant hepatic failure, two patients with urinary polyamine concentrations above 100 mumoles/g.cr. recovered, while two patients with concentrations of 56.2 and 26.7 mumoles/g.cr., died. In acute hepatitis, urinary polyamine excretion was significantly less in the recovery stage compared with the acute stage. When insulin and glucagon infusion therapy was performed in patients with liver cirrhosis without ascites, urinary polyamine excretion was significantly elevated after three days. These results suggest that measuring the amount of polyamine in urine is clinically useful for monitoring hepatic regeneration.

We examined the level of plasma amino acids, glucose, immunoreactive insulin (IRI) and immunoreactive glucagon (IRG) of patients in the fasted state with acute hepatitis in the actual acute stage (AHa), acute hepatitis in the convalescent stage (AHc), chronic active hepatitis (CAH), chronic persistent hepatitis (CPH) and liver cirrhosis (LC). In AHa patients, the plasma glucose (FPG), plasma alanine (Ala), tryptophan (Trp) and histidine (His) levels were significantly lower and plasma cystine (Cys) level significantly higher than the control levels. This however, was not the case in the other patients. The glutamic acid (Glu) concentration was significantly higher in AHa (p less than 0.02), CAH (p less than 0.001) and CPH (p less than 0.001) and the tyrosine (Tyr) concentration was significantly higher in AHa (p less than 0.02), CPH (p less than 0.001), CAH (p less than 0.001) and LC (p less than 0.001) than they were in the controls. The lysine (Lys) concentration was significantly raised in the AHa (p less than 0.02) and CPH (p less than 0.05) cases. The IRG level was significantly higher in AHa (p less than 0.001), in AHc (p less than 0.01) and LC (p less than 0.01). Valine (Val) showed a significant decrease in concentration in AHa (p less than 0.01) and LC (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

In this study, the side-to-side (MCS-SS) and end-to-side (MCS-ES) mesocaval shunt were performed in two groups of thioacetamide (TAA)-induced cirrhosis of rats. The anastomotic stoma was made equal to the calibre of mesenteric veins. It was found that the portal vein pressure after MCS-SS was lower than that after MCS-ES owing to the more effective drainage of both extra- and intrahepatic portal blood flow. It was also found that with MCS-SS, some inflow from the superior mesenteric vein was reserved to irrigate the liver and the content of insulin in the portal vein was not affected. The authors came to the conclusion that MCS-SS was superior to MCS-ES for less likely causing post-shunt encephalopathy and the deterioration of hepatic function.

Insulin action on carbohydrate metabolism is known to be reduced in liver cirrhosis. However, little is known about the effect of insulin on free fatty acid (FFA) metabolism in these patients. To investigate this aspect we performed a two-step insulin euglycemic clamp in 11 cirrhotic patients and 6 controls. Insulin was infused at 0.25 mU/Kg min from 0 to 100 min and at 1 mU/Kg from 100 to 200 min. The FFA lowering capacity of insulin was studied during the first step; the glucose metabolizing capacity (M) was evaluated during the second step. In the cirrhotic patients, the M value was lower than in controls (3.91 +/- 0.48 vs 7.75 +/- 1.09 mg/kg/min, respectively). During the low insulin infusion, FFA and glycerol plasma levels were decreased in both groups. However, the ability of insulin to suppress plasma FFA and glycerol was lower in cirrhotics than in controls. In fact, at 100 min, FFA were 50% of basal values in cirrhotics and 20% in controls (p less than 0.01), while glycerol plasma levels decreased to 70% of basal values in patients and to 56% in controls. The slope of the linear regression obtained between Ln-FFA concentrations vs time was significantly less in cirrhotic patients than in controls (p less than 0.001). In addition, a positive correlation was found between the M value (r = 0.70; p less than 0.01) and the slope of the Ln-FFA in each patient. These findings suggest that in cirrhotic patients the effects of insulin on both FFA and glucose metabolism are reduced.
