Exogenous hepatic coma was found 102 times (group A) and a combination of exogenous and endogenous hepatic coma 50 times (group B) in 152 patients with hepatic coma. The most frequent eliciting factors in group A were too high a protein supply and gastrointestinal hemorrhage and diuretics, in group B necrotic exacerbations and infections, 2/3 of them having severe portal hypertension with ascites and esophageal varices at the same time. A typical fetor hepaticus was found in only 25% of group A and 50% in group B. 10% had a primary liver cell carcinoma. The prognosis depends largely on the stage of the coma and the treatment of the eliciting factors. Altogether 50 of the 152 hepatic coma patients died. The most frequent complication was a terminal renal failure which no longer responded to therapy.

The blood levels of 25-hydroxyvitamin D (25-HCC) in 26 patients with nephrotic syndrome (proteinuria of 6.5 g/24 h +/- 0.8 SEM) ranged between 1 and 18.6 ng/ml (8.6 +/- 1.0 SEM). This value was significantly lower (P less than 0.01) than that in normal subjects (21.8 +/- 2.3 ng/ml) and patients with chronic renal failure (24.8 +/- 2.3 ng/ml). There was inverse correlation (P less than 0.01) between levels of 25-HCC and magnitude of proteinuria and a direct relation (P less than 0.01) with serum albumin. Reduction in proteinuria was rapidly followed by a rise in blood 25-HCC toward normal. Ionized calcium levels were low in 16 of 26 nephrotic patients irrespective of degree of renal failure. In four of seven nephrotic patients with normal renal function, ionized calcium levels were low and showed an inverse relation with levels of parathyroid hormone. These data show that patients with nephrotic syndrome have low blood levels of 25-HCC probably due to its loss in urine. This derangement is probably responsible for the disorders of calcium metabolism in nephrosis.

Nine patients with bleeding from a ruptured hepatocellular carcinoma had absolute alcohol injection. Laparotomy and alcohol injection stopped the bleeding in seven patients. Injection under laparoscopic visualization was attempted in two patients and in one patient haemostatis was achieved initially. He rebled, however, 4 h later and laparotomy failed to control the bleeding. He died 2 days later because of coagulopathy and renal failure. In the second patient, bleeding was not controlled laparoscopically and immediate laparotomy and alcohol injection stopped the bleeding. The eight patients who survived left hospital between 8 and 21 days after surgery (median 10 days). In our experience, laparotomy and alcohol injection achieved good results in bleeding hepatocellular carcinoma.

We describe a modified RIA using a rabbit polyclonal antiserum directed against the first 21 amino acids of the E-domain (E-21) of proinsulin-like growth factor-II (pro-IGF-II). For standardization, we purified big IGF-II from patients with nonislet cell tumor hypoglycemia (NICTH). Under the conditions of our assay there was no significant interference from IGF-binding proteins. The big IGF-II present in the serum of a patient with NICTH displaced [125I]E-(1-21) from antibody parallel to our big IGF-II standard. We found a progressive rise in E-21 immunoactivity (IA) during childhood, with somewhat higher values in girls than in boys. In normal adults the mean E-21 IA level was 138 +/- 49 (+/- SD) micrograms/L. Women with twin pregnancies had higher E-21 IA than women with single pregnancies (302 +/- 66 compared with 120 +/- 18 micrograms/L). We found a marked elevation of E-21 IA in patients with NICTH due to sarcomas (n = 3), hepatoma (n = 2), adrenal carcinoma (n = 1), and carcinoma of the lung (n = 1). No elevation of E-21 IA was present in the serum of a hypoglycemic patient with a hypernephroma or another patient with carcinoma of the lung. Marked elevation of E-21 IA was observed in the serum of patients with renal failure receiving chronic hemodialysis. We conclude that this assay will prove useful in the diagnosis of NICTH in patients who are not azotemic and the investigation of the role of the kidney in clearing products of pro-IGF-II processing.

Sixty-six consecutive patients with unresectable hepatocellular carcinoma (HCC) were treated with transcatheter arterial chemoembolization (TACE) using aclarubicin microspheres (ACRms) in combination with cisplatin suspended in iodized oil (Lipiodol, Laboratoire Guerbert, Paris, France) (CSL). The stages of the disease were as follows: Stage I (n = 1), Stage II (n = 10), Stage III (n = 26), and Stage IV (n = 29). The effectiveness of TACE was assessed by comparing ACRms with CSL with ACRms without CSL. Of 66 patients treated with ACRms and CSL, 62 (93.9%) could be examined for response. According to response criteria, there were 31 (50.0%) partial responses and 17 (27.4%) minor responses. In 13 cases (21.0%) there was no change and in 1 case (1.6%) there was progressive disease. The cumulative survival rate was 80.7% at 1 year, 64.2% at 2 years, and 50.6% at 3 years. The rates were significantly higher than those of the group treated with ACRms. Eleven patients in the ACRms and CSL group experienced clinical complications: cholecystitis (4.5%), pancreatitis (3.0%), liver abscess (3.0%), hepatic failure (3.0%), gastrointestinal bleeding (1.5%), and renal failure (1.5%). No lethal side effects related to the therapy were observed. TACE using ACRms in combination with CSL prolongs the survival of patients with unresectable HCC.

Variceal bleeding has a high mortality, as the majority of patients have cirrhosis, with hepatic coma, renal failure, ascites and clotting deficiencies as complicating factors. Bleeding varices must therefore be treated as an emergency. Resuscitation, endoscopic diagnosis and haemostasis are the cornerstones of treatment. Once bleeding varices have been identified, attempts to stop the bleeding must be made at once as this will lessen the chances of hepatic failure developing. Endoscopic sclerotherapy at the time of diagnosis is the best available treatment at present, although profusely bleeding varices can be difficult to see and inject. In these circumstances the passage of a Sengstaken tube should stop the bleeding, allowing later sclerotherapy to be successful. If rebleeding recurs and cannot be controlled, oesophageal transection with a stapling gun may be life-saving, although the varices may later recur and long-term endoscopic follow-up will be necessary. Portacaval shunting and the distal splenorenal shunt involve arduous surgery and are followed by a significant incidence of hepatic encephalopathy; they should be reserved for those few cases when simpler measures have failed, although shunts do lead to permanent decompression of the portal system. The acute variceal bleed may also be dealt with pharmacologically. Vasopressin, used in combination with nitroglycerin to lessen the harmful side-effects, is cheaper and as effective as terlipressin or somatostatin and its synthetic analogue octreotide. Several courses of injection sclerotherapy will be required to eliminate oesophageal varices. Thereafter, long-term follow-up will be necessary to deal with any recurrence. The place of non-selective beta-blockers is still contentious, but they do reduce portal pressure and may lessen the chance of rebleeding. There is also a growing role for hepatic transplantation, which not only eliminates the varices but also restores liver function to normal and greatly reduces the risk of subsequent hepatoma development.

Non-A, non-B hepatitis, recently renamed as hepatitis C virus (HCV), accounts for over 90% of hepatitis cases worldwide associated with blood transfusions. Application of a recombinant-based enzyme immunoassay for the detection of antibodies to HCV to a sample of 500 male Saudi blood donors and 260 healthy Saudi pregnant women indicated that HVC is endemic in the Saudi population. Anti-HCV was detected in 28 (5.6%) of the blood donors and 12 (4.6%) of the pregnant women, for an overall frequency of 5.3% in healthy Saudi adults who had never received blood transfusions. This rate is at least 5 times higher than that reported for the US and Western Europe. Also assessed was the HCV rate in subsamples of Saudis considered at risk of this infection. Here, anti-HCV was detected in 22 (78.6%) hemophiliacs, 26 (33.3%) patients with thalassemia and sickle cell disease, 17 (26.1%) hemodialysis patients with renal failure, and 35 (15.9%) individuals with a sexually transmitted disease. The prevalence of anti-HBc ranged from 28% in blood donors to 46% in hemophiliacs. The significantly higher prevalence of HCV in patients with sexually transmitted diseases than in blood donors suggests that this disease is transmitted through heterosexual contact as well as blood transfusions. Given the high baseline level of HCV infection in the Saudi population and the possibility of serious sequelae (e.g., chronic active hepatitis, cirrhosis, and hepatocellular carcinoma), routine anti-HCV screening of blood donations is urged.

One hundred and one cases of hepatocellular carcinoma (HCC) treated in Maebashi Red Cross Hospital from May 1984 to August 1987 were classified according to the therapy and progression of the disease and were investigated on their prognosis. Furthermore, "long survived group" in which, patients survived for more than one year were compared with "short survived group" in which patients died within one month after non-surgical treatment. In operated patients, the prognosis was the best, but the rate of operable cases was only 13.9%. In patients with stage IV, one year survival rate was significantly low. In patients with portal trunk invasion (Vp4), or with Child C that was the poorest functional reserve of the liver, one year survival rate was also significantly low in comparison with patients with other stages or other Child's classification. In HCC patients treated with transcatheter arterial embolization (TAE), the prognosis tended to be poor as stage and portal invasion progressed, but in regard to reserve function of the liver, the prognosis was not so poor in patients of Child C significantly as in cases of A or B. The comparisons between long and short survived group were as follows. a) In 17 cases belong to long survived group, mean survival period was 24 months and the longest one was 4 years and 10 months. On the other hand, in 10 cases belong to short survived group, mean survival period was 17 days, the shortest one was 3 days. b) The main reason of inoperability in long survived group was progression of the tumor. Complications such as diabetes mellitus, advanced age and rejection of treatment by the patient were the other reasons of in operability. In almost half of the patients in short survived group, the tumor progression and low functional reserve of liver were found in 4 patients. c) In short survived group, esophageal varices were more common and functional reserve of the liver was poorer than in long survived group. In short survived group, LDH and total bilirubin were significantly higher than those of long survived group, but there was no significant differences in transaminase value and ICG retention in 15 minutes. d) In short survived group, extent of the tumor in liver and portal invasion were advanced. Three cases of this group (30%) had distant metastasis. e) In long survived group, the main reason of death was hepatic failure. Renal failure, or pulmonary complications were also found in short survived group.(ABSTRACT TRUNCATED AT 400 WORDS)

Hepatic arterial infusion chemotherapy with cisplatin (CDDP) and adriamycin (ADR) in combination with angiotensin-II (AT-II) was performed in 19 cases of hepatocellular carcinoma (HCC), 16 cases of metastatic liver tumor (MLT) and one case of cholangiocellular carcinoma. CDDP (60-120 mg) and ADR (20-50 mg) were infused into the hepatic artery with intra-arterial instillation of AT-II (0.5-1.5 microgram/min). Transcatheter arterial embolization (TAE) was additionally performed in 10 cases of HCC and 3 cases of MLT. The response rates for infusion chemotherapy combined with TAE were 44% in HCC and 67% in MLT. On the other hand, the response rates without TAE were 0% in HCC and 42% in MLT. In some cases of HCC, however, a marked decrease in serum alpha-fetoprotein levels was observed despite the lack of effectiveness evaluated by CT scan and angiography. Although minor side effects were noted such as a mild degree of leukocytopenia and/or thrombocytopenia and hepatic and/or renal dysfunction, they were only temporary with a duration of less than 3 or 4 weeks. In 4 patients with HCC without TAE treatment, however, lethal side effects occurred including pancytopenia, hepatic failure and disseminated intravascular coagulation, and they died within 2 months after infusion chemotherapy. Renal failure was not seen in either group.

Previous studies have suggested that molecular species larger than the mature calcitonin (CT) are produced by tumors of different origin. In order to study these species, we developed a monoclonal immunoradiometric assay for calcitonin precursors (CT-pr). This assay was based on both monoclonal antibody KC01 directed to the 1-11 region of katacalcin and monoclonal antibody CT08 directed to the 11-17 portion of CT. The sensitivity of this monoclonal immunoradiometric assay for CT-pr was less than 100 pg/ml. Only one of 131 healthy subjects had CT-pr serum levels greater than 100 pg/ml; this value was therefore selected as the standard serum value in healthy individuals. CT-pr was present in the serum of seven of ten patients with advanced renal failure and in that of 21 of 52 patients (40%) with benign liver disease but was undetectable in sera of patients with other benign diseases. The serum CT-pr level was correlated with that of mature CT in patients with medullary carcinoma of the thyroid. In contrast, the serum CT-pr level was frequently elevated in the absence of a detectable CT level in patients with various malignant tumors and, particularly, in those with either tumors of the neuroendocrine system (60%) or hepatocellular carcinomas (62%). CT-pr was detected in tumor extract from a patient with a hepatocellular carcinoma. Moreover, hybridization experiments with total RNA extracted from this tumor demonstrated the presence of RNAs hybridizing with complementary DNA encoding for common region, calcitonin, and katacalcin sequences. These results show that CT precursors are excreted by numerous cancers and might well be useful biological markers for the follow-up of productive tumors.
