Prothrombin time, serum albumin, aminotransferases and liver size were evaluated in 40 consecutive cases of kwashiorkor. Eleven (27.5%) of the 40 patients died. Eight out of the 11 patients who died had a prolonged prothrombin time of more than 3 s above the control compared to only 4 out of the 29 who survived (p = 0.005). Mean serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) albumin, globulin and liver size were abnormal but similar in both groups. These results may indicate a predictive mortality value of prothrombin time in kwashiorkor.

It is common for general practitioners (GPs) to refer patients suspected of impaired liver function for laboratory tests (alkaline phosphatase, lactate dehydrogenase, bilirubin, prothrombin, aspartate aminotransferase). In a prospective multipractice study over a six-month period, including 30 GPs, 55 patients were recorded as having, for the first time, a high level of alkaline phosphatase (AP) as an isolated finding, 14 with an increase of aspartate aminotransferase (ASAT), eight with an increase of both AP and ASAT, three with an increase of ASAT, AP, and bilirubin, two with an isolated increase of lactate dehydrogenase (LDH), one with an increase of ASAT, AP, and bilirubin, combined with a low prothrombin (PP), and, finally, one patient with a low prothrombin in isolation. In most cases the tests were requested because of unspecific symptoms. The most common causes of abnormal test results were neoplasms, alcoholic liver disease, and heart failure. Thirty patients were referred to hospital for further investigations. During the same study period, 50 patients with known abnormal liver function tests were recorded, and the most common causes of these abnormalities were neoplasms, rheumatoid arthritis, and alcoholic liver disease.

Hydrated sodium calcium aluminosilicate (HSCAS), an anticaking agent for mixed feed, was added to the diets of growing wethers (mean body weight, 34.0 kg) and was evaluated for its ability to diminish the clinical signs of aflatoxicosis. The experimental design consisted of 4 treatment groups of 5 wethers each, consuming concentrations of 0 g of HSCAS and 0 g of aflatoxin (AF)/kg of feed (control; group 1); 20 g of HSCAS/kg (2.0%; group 2), 2.6 mg of AF/kg (group 3); or 20 g of HSCAS (2.0%) plus 2.6 mg of AF/kg (group 4). Wethers were maintained in indoor pens, with feed and water available ad libitum for 42 days. Lambs were observed twice daily and weighed weekly, and blood samples were obtained every 2 weeks for hematologic and serum biochemical analyses and for measurement of mitogen-induced lymphocyte-stimulation index. At the termination of the study, wethers were euthanatized and necropsied. Body weight gain was diminished significantly (P less than 0.05) by consumption of 2.6 mg of AF/kg of feed, whereas body weight of lambs consuming HSCAS plus AF did not differ from that of control wethers. The AF-alone treatment increased serum aspartate transaminase and gamma-glutamyltransferase activities, prothrombin time, and cholesterol, uric acid, and triglyceride values and decreased albumin, glucose, and urea nitrogen values, and urea-to-creatine ratio.(ABSTRACT TRUNCATED AT 250 WORDS)

A 49 year old female was started on disulfiram. Six weeks later she was given naproxen because of epicondylitis. After 5 days' treatment with naproxen she complained of nausea, anorexia and jaundice. At admission, bilirubin was 452 mumol/l, aspartate aminotransferase (ASAT) 1925 U/I, alanine aminotransferase (ALAT) 2815 U/I and prothrombin time measured as Normotest was 27%. The patient developed a fulminant hepatitis and died in hepatic coma almost four weeks after the introduction of naproxen. Postmortem examination disclosed a small liver (1,100 g) and histological examination showed massive necrosis and collapse of the lobules. The naproxen was the most probable cause of death, but it is impossible to exclude disulfiram as causative agent.

Indocyanine green clearance was measured in 23 symptomatic patients with primary biliary cirrhosis who were followed up for 6 months. Ten patients either died (n = 4) from their primary biliary cirrhosis or underwent liver transplantation (n = 6) during the follow-up period. Indocyanine green clearance and other liver function test results were compared between the survivors (n = 13) and those who had died or undergone transplantation (n = 10). Indocyanine green clearance, bilirubin, bile acids, albumin, and prothrombin ratio differed significantly between the two groups, whereas age, alkaline phosphatase, globulin, and aspartate aminotransferase did not. Indocyanine green clearance gave better discrimination between the two groups than the other liver function tests, including bilirubin. There was a close correlation between indocyanine green clearance and bilirubin in patients who died or were transplanted. Further studies are necessary to define whether indocyanine green clearance is clinically useful in selecting patients for transplantation and in the timing of intervention.

The effects of soman poisoning on hematological (counts of red blood cells (RBC), white blood cells (WBC), and platelets and measurement of hematocrit) and coagulation parameters (prothrombin time, activated partial thromboplastin time, thrombin time and concentrations of fibrinogen, factor V, factor VII, and factor XI) and serum biochemistry (concentration of albumin, protein, calcium, cholesterol, triglycerides, blood urea nitrogen (BUN), magnesium, and creatinine and activities of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, cholinesterase, creatinine phosphokinase (CPK), hydroxybutyrate dehydrogenase, and amylase) were determined at 1, 2, 4, 24, and 48 hours after poisoning of rabbits. There were significant (p less than 0.05) decreases in the RBC counts in all treatment groups that were measured initially at 4 hours and were reflected by parallel decreases in the hematocrit values. These changes were probably due to an increase in the hemolysis of the RBC rather than a decrease in the production of RBC. There were minor changes in the coagulation parameters. Generally, the fibrinogen content increased. The activated partial thromboplastin time decreased significantly (p less than 0.05) 24 and 48 hours after soman (50 micrograms/kg) poisoning. Blood cholinesterase values were significantly reduced in all treatment groups at all time periods. The CPK activity was increased after 4 and 24 hours in the 20 and 50 micrograms/kg soman groups. There were minor changes in the other biochemistry values, but none that showed a dose-response relationship; thus, they were considered to be of limited significance with regard to the toxic manifestations of soman exposure.(ABSTRACT TRUNCATED AT 250 WORDS)

Colchicine treatment was used in this randomized placebo-controlled trial in patients with severe acute alcoholic hepatitis [serum bilirubin greater than or equal to 5 mg/dL (85.5 mumol/L) mean, 17.5 +/- 7.5 mg/dL (299.25 +/- 128.25 mumol/L)]. Hospitalization mortality and morbidity and the effect on biochemical test results were the end points of the treatment. Patients in the two groups were evenly matched by demographics and laboratory test results. Mean time to study entry was less than 7 days from admission. The duration of the trial was 30 days. Thirty-six patients (24 men, 12 women) received colchicine (1 mg orally every morning) and 36 (25 men, 11 women) received an identical placebo. Seven (19%) colchicine-treated and six (17%) control patients died during the index hospitalization after a mean of 17.4 +/- 10.8 and 17.8 +/- 5.3 days, respectively (NS). During a 4-month follow-up period from entry into the trial, there were two additional deaths in each group. No differences between placebo- and colchicine-treated patients were observed in any of the laboratory parameters (serum bilirubin, aspartate transaminase, alanine transaminase, prothrombin activity, albumin, white blood cell count, hemoglobin, and creatinine) that were followed up over the 30-day treatment period. The frequency of complications did not differ statistically between the two groups. This study showed no effect of colchicine treatment on mortality and morbidity of severe alcoholic hepatitis. Colchicine cannot be recommended for the treatment of patients with alcoholic hepatitis.

Effects of dietary aflatoxin (AF) and T-2 toxin, singly and in combination, were evaluated in growing crossbred (Yorkshire x Landrace x Hampshire) pigs. The experimental design consisted of 4 treatment groups of 6 barrows each fed diets containing 0 mg of AF and T-2/kg of feed (controls; group 1), 2.5 mg of AF/kg of feed (group 2), 10 mg of T-2/kg of feed (group 3), or 2.5 mg of AF plus 10 mg of T-2/kg of feed (AF + T-2; group 4) ad libitum for 28 days (7 to 11 weeks of age). Production performance, and serum biochemical, and hematologic evaluations were made weekly. Body weight and body weight gain were depressed by all toxin treatments, but the effect of AF and T-2 toxin in combination was less than additive. Liver and kidney weights, as a percentage of body weight, were increased by AF treatment, and heart weight, as a percentage of body weight, was increased by T-2 treatment. Treatment with T-2 toxin induced necrotizing contact dermatitis on the snout, buccal commissures, and prepuce. Consumption of AF resulted in increased serum activities of alkaline phosphatase, aspartate transaminase, cholinesterase, and gamma-glutamyltransferase, and decreased serum concentrations of urea nitrogen, cholesterol, albumin, total protein, calcium, potassium, magnesium, and phosphorus. Consumption of T-2 toxin resulted in increased serum triglyceride concentration and decreased serum iron concentration. Treatment with AF induced lower serum unsaturated iron-binding capacity and high RBC count, PCV, hemoglobin concentration, WBC count, and prothrombin time.(ABSTRACT TRUNCATED AT 250 WORDS)

Scarcity of small donors results in a high mortality rate for children on liver transplant waiting lists. To alleviate this problem, we have recently started to reduce the size of livers from older donors to use in children. In the last year, a total of 20 liver transplants were performed in 17 patients, including seven reduced-size liver transplants (RSLT) in six children. Mortality on the waiting list has been reduced to negligible amounts compared with a mortality rate of 25% before starting RSLT in patients with acute liver failure or those whose weight was less than 10 kg. Children undergoing RSLT weighed 10.8 +/- 8.5 kg compared with 20.9 +/- 20.3 for all others (NS). Cold ischemia time was significantly longer in the RSLT group (9.5 +/- 3.0 v 6.0 +/- 2.8 hours, P less than .05) as was intraoperative blood loss (9.4 +/- 9.4 v 3.0 +/- 3.5 blood volumes). There was no significant difference in postoperative aspartate aminotransferase and prothrombin time between the two groups. Four children received a RSLT as a primary procedure and three have survived with good liver function. Two patients were retransplanted with RSLT after a failed first transplant and both died of nonhepatic complications. This compares with 11 of 13 survivors in the whole liver transplant group. Causes of death in children who died after RSLT include cytomegalovirus sepsis (2) and myocardial infarction(1).(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatic dysfunction was observed in 34 patients with nontraumatic rhabdomyolysis. The serum levels of lactic dehydrogenase were markedly elevated in all patients. The peak values occurred within 72 h of hospitalization. There was no significant difference among patients with (9,044 +/- 1,154 U/l) and without acute renal failure (ARF; 9,125 +/- 3,067 U/l). Similarly, marked elevation in both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were observed within 72 h after admission to the hospital. They were significantly higher in patients with ARF (ALT: 4,718 +/- 785 vs. 2,496 +/- 927 U/l, p less than 0.01; AST: 3,635 +/- 820 vs. 1,352 +/- 624 U/l, p less than 0.01). Hyperbilirubinemia was noted in 13 of 22 (60%) patients with ARF and in 5 of the 12 (41%) of those without ARF. Serum levels of bilirubin ranged from 2.6 to 14.3 mg/dl. Prothrombin time was prolonged in 4 of 12 (33%) without ARF and in 14 of 22 (63%) of patients with ARF. This abnormality lasted from 1 to 13 days. The magnitude and duration of hyperbilirubinemia and abnormal prothrombin time were similar in patients with and without ARF. Hepatic dysfunction appears to occur in about 25% of patients with rhabdomyolysis. The pathogenesis of these abnormalities is not well defined and may be multifactorial. Hyperpyrexia, hypotension and proteases released from injured muscle may each or all be contributory. These hepatic derangements are reversible.
