Insulin-like growth factor II is secreted primarily by the liver and is reported to be transcribed in many primary hepatocellular carcinoma (PHC) cell lines. We have studied diagnostic significance of serum IGF-II in chronic liver diseases using specific enzyme immunoassay. Serum IGF-II levels (mean +/- SE) were decreased in chronic hepatitis (538 +/- 51 ng/ml; N = 29), liver cirrhosis (427 +/- 45; 50) and PHC (260 +/- 41; 17) compared to controls (830 +/- 49; 57). Serum IGF-II was not different from controls in any of nonhepatic diseases such as diabetes (1032 +/- 97; 19) pancreatic cancer (1413 +/- 282; 8), chronic pancreatitis (999 +/- 126; 17), peptic ulcer (1186 +/- 43; 11), irritable bowel syndrome (1002 +/- 109; 12), gastrointestinal tract cancer (1250 +/- 216; 21) and chronic renal failure (733 +/- 135; 14). In liver diseases serum IGF-II showed a significant correlation with liver function test (negative with retention of indocyanine green and total bile acids; positive with albumin, thrombo-test, and cholinesterase). These results suggest that serum IGF-II reflects a reduced production of IGF-II in the liver and that it can be an index for the residual capacity of liver function.

Studies were performed to investigate the relationship between serum interleukin-6 (IL-6) and the nutritional status in chronic hemodialysis patients. Serum IL-6 in 45 patients (21 men and 24 women), each with chronic renal failure and having undergone hemodialysis for more than 3 years, was measured before and after a dialysis session. The nutritional status of each patient was evaluated by measuring body mass index (BMI), body weight loss for 3 years, midarm muscle area (MAMA), serum albumin, prealbumin, and insulin-like growth factor-1. Serum IL-6 was significantly higher in the patients undergoing hemodialysis (11.7 +/- 2.8 pg/mL) than in healthy volunteers (< 0.6 pg/mL). There was no further increase in serum IL-6 after a dialysis session when the extracellular water volume was corrected by the ultrafiltrate volume. Predialytic serum IL-6 was significantly correlated with serum albumin (r = -0.4, P = 0.006), cholinesterase (r = -0.51, P = 0.001), body weight change for 3 years (r = -0.48, P = 0.001) and MAMA r = -0.39, P = 0.05). With the patients divided into two groups, a high serum IL-6 (>10 pg/mL) group and low serum IL-6 (<10 pg/mL) group, the body weight loss for 3 years (-4.60% +/- 1.39% v 0.76 +/- 0.75%, P < 0.01) was significantly higher, and the serum albumin level (3.66 +/- 0.10 g/dL v 3.96 +/- 0.05 g/dL, P < 0.05) was significantly lower in those patients with high serum IL-6 than in those with low serum IL-6. The results of a multiple regression analysis indicated that the serum IL-6 level was dependent on the duration of hemodialysis, age, and the dialysis membrane properties. These results suggest that the nutritional status in chronic hemodialysis patients was affected, at least in part, by the circulating IL-6 level. Multiple factors, such as long-term hemodialysis, aging, and the use of a regenerated cellulose membrane dialyzer, were associated with this increased level of IL-6.

Aim of the study was to evaluate serum levels of insulin-like growth factor binding protein-3 in patients with liver cirrhosis and to compare serum IGFBP-3 levels with other liver function tests. Fifty-one patients with liver cirrhosis were selected for our study. We measured IGFBP-3 (1.67+/-1.06 mg/l, mean+/-SD), albumin (32+/-8 g/l), prealbumin (0.22+/-0.14 g/l), AST (2.29+/-2.38 microkat/l), ALT (2.11+/-4.83 microkat/l) and cholinesterase (mean 78.6+/-45.2 microkat/l) in the serum. There was a significant positive correlation of serum IGFBP-3 with serum albumin and serum cholinesterase. The correlation coefficient was much lower between serum IGFBP-3 and serum prealbumin. There was no significant correlation between serum AST, ALT and IGFBP-3. Serum IGFBP-3 proves to be a better marker for the hepatic synthetic capacity than serum albumin or cholinesterase.

In the present work, we tested the hypothesis that target-derived insulin-like growth factor-1 (IGF-1) prevents alterations in neuromuscular innervation in aging mammals. To explore this hypothesis, we studied senescent wild-type mice as a model of deficient IGF-1 secretion and signaling and S1S2 transgenic mice as a tool to investigate the role of sustained overexpression of IGF-1 in striated muscle in neuromuscular innervation. The analysis of the nerve terminal in extensor digitorum longus muscles from senescent mice showed that the decrease in the percentage of cholinesterase-stained zones (CSZ) exhibiting nerve terminal branching, number of nerve branches at the CSZ, and nerve branch points was partially or completely reversed by sustained overexpression of IGF-1 in skeletal muscle. Target-derived IGF-1 also prevented age-related decreases in the postterminal alpha-bungarotoxin immunostained area, as well as the reduction in the number and length of postsynaptic folds, and area and density of postsynaptic folds studied with electron microscopy. Overexpression of IGF-1 in skeletal muscle may account for the lack of age-dependent switch in muscle fiber type composition recorded in senescent mice. In summary, the use of the S1S2 IGF-1 transgenic mouse model allowed us to provide morphological evidence for the role of target-derived IGF-1 in spinal cord motor neurons in senescent mice.
