Procainamide acetylation and hydrolysis, procainamide-derived p-amino-benzoic acid acetylation, and plasma hydrolysis of procaine were studied in normal volunteers and in 20 patients with chronic liver disease, Impairment of procainamide acetylation was evident in the patients, but no correlations were demonstrable between the degree of impairment and the severity of the disease. On the other hand, procainamide hydroylsis was diminished in liver disease, and as indicated by depression of serum albumin levels and plasma prothrombin activity this alteration did correlate with the degree of impairment of liver function. Procaine hydrolysis in plasma was also affected, the mean in vitro plasma half-life being prolonged in the patients with liver disease and correlating with the degree of hepatic impairment. A correlation of procainamide hydrolysis with procaine hydrolysis was also observed. Finally, acetylation of procainamide-derived p-aminobenzoic acid appeared to increase in patients with liver disease, the degree of acetylation increasing with decreasing procainamide hydrolysis capacity.

An outbreak of chronic liver disease was investigated in a kennel of dogs. Anorexia, depression, polyuria, polydipsia, icterus and a terminal hemorrhagic diathesis were noted in clinically affected dogs. Thrombocytopenia, hypofibrinogenemia, elevated fibrinogen degradation products and prolonged activated partial thrombosplastin times (PTT) and one-stage prothrombin times (PT) were associated with the hemorrhagic crisis. Aflatoxicosis was confirmed by the presence of significant levels of aflatoxicosis was confirmed by the presence of significant levels of aflatoxin B in the commercial dog food being fed. A subacute hepatitis was found on necropsy. Disseminated intravascular coagulation was suspected as the cause of the hemorrhage in these cases and treatment was instituted.

Factor VII levels have been measured in 100 patients with liver disease following parenteral vitamin K1 therapy. There was good agreement between specific factor VII measurements and the one-stage prothrombin time apart from six patients with compensated cirrhosis in whom the prothrombin time was prolonged despite the presence of normal factor VII levels. A mean activity of 58% was found in patients with cirrhosis. Cirrhotic patients with features of hepatic decompensation had a significantly lower mean level of activity (40%) than the "contrast" patients with surgical obstruction of the major bile ducts (93%). Patients with chronic active liver disease had moderate depression of factor VII levels and those with non-cirrhotic liver damage had mean activities similar to the contrast group. Factor VII levels could not be correlated with BSP retention but there was a correlation with serum albumin concentration. It is concluded that the prothrombin time using Quick test with a standardized thromboplastin showing good sensitivity to factor VII, eg, the Manchester reagent (BCT), provides a reliable index of coagulability in chronic liver disease, and specific factor VII assays are not indicated.

Considering the increasing number of liver transplantations with longer periods of transplant function, there is a growing need for quality of life research in the field. In addition to lethality, mortality and rehabilitation, parameters of 'quality of life' are to be evaluated: the patient's rating of his subjective physical symptoms, psychological condition (anxiety, depression and mental adjustment), social reintegration and life satisfaction. This paper describes our psychological support program that has been established at the Hamburg LTX center as well as the first results of the ongoing QoL research study. Using the methods developed by the Hamburg Study group on 'quality of life in surgery', 38 liver transplantation patients of the University of Chicago (cross-sectional study with control groups of patients with chronic liver disease as well as healthy individuals) and 29 patients of the University Clinic of Hamburg (longitudinal study with points of evaluation before and 2, 6, 12, 24 and 36 months after transplantation) have been evaluated. First results: (1) All successfully transplanted patients show a significant postoperative increase of their overall quality of life. (2) The psychological parameters of quality of life are only partly correlated with physical symptoms. (3) There is a high correlation between rejection crisis periods and the decrease of all quality of life parameters. (4) In both samples men have a lower quality of life than women, (5) Preoperative depression and lack of social support might be considered as being possible risk factors for long-term survival. (6) Long-term survivors rate their quality of life significantly higher than patients with chronic liver disease and--despite some persisting somatic restrictions--as high as healthy controls. (7) A psychotherapeutic support program increases the patient's compliance resulting a better adaption to the transplant procedure including rehabilitation.

During the past decade a new approach to pathogenetic studies of hepatic encephalopathy has been undertaken to identify the neurochemical alterations which characterize the syndrome. Using animal models of hepatic encephalopathy electrophysiological, behavioral, pharmacological and biochemical evidence were provided of an increased functional activity of the GABA-A receptors, including the Benzodiazepine site. These demonstrations seem to explain the increased sensitivity of patients with acute or chronic liver disease to sedative administration. The described increased tone of the GABAergic receptor complex seems to play a key role in the generalized depression of the central nervous system which characterizes hepatic encephalopathy, but other factors seem to contribute to the neuronal derangement present in this syndrome leading to an imbalance between inhibitory and excitatory receptor systems in the brain. Based on these findings a new symptomatic treatment with anti-benzodiazepine compounds which seem temporarily to counteract the symptoms of hepatic encephalopathy, was introduced.

Acute causes and chronic risk factors for the development of acute renal failure were analyzed in prospective acquired data of 261 patients in a medical ICU. The population was divided into a group requiring dialysis treatment for established renal failure (n = 95) and a collective maintaining mild renal insufficiency (n = 166). Bivariate and linear discriminant analyses revealed that, above all, variables related to bacterial infections (sepsis and administration of antibiotic agents) and pancreatitis contributed to the discrimination, followed by bleeding, volume depletion, and chronic liver disease in the discriminant function. Bivariate analysis also yielded significant results for mechanical ventilation, CNS depression, and surgery. The importance of the nephrotoxic properties of aminoglycosides may be outweighed by their role as an indicator of severe infectious disease. The overall correct classification rate of the discriminant function was 78.5%, which reflects the importance of the predictor variables, but does not allow individual predictions.

To characterize type and age distribution of malnutrition and to determine the usefulness of anthropometric indices in children with chronic liver disease (CLD), 56 children (aged 1 mo-10 y) with CLD underwent anthropometric evaluation when they were clinically stable. Mean-height Z score was depressed, whereas mean-weight Z score was closer to normal and mean-weight/height Z score was normal in patients with extrahepatic biliary atresia, idiopathic neonatal hepatitis, and other liver disorders. Patients with arteriohepatic dysplasia showed more severe depression of all three variables. In all patients, triceps skinfold (TSF) thickness Z scores were significantly more depressed than were weight/height Z scores. Depressions of midarm-circumference and midarm-muscle-area Z scores were intermediate. Mean-head-circumference Z score was depressed in children aged less than 24 mo. We conclude that acute (wasting) and chronic (stunting) malnutrition are common in childhood CLD and that weight/height values underestimate the degree of acute malnutrition compared with TSF thickness, most likely because of the inflated patient weight caused by organomegaly.

Between 1970 and 1983, we performed 1121 diagnostic laparoscopies in 1119 patients. More than 50% of the examinations were performed for malignant disease. An adequate examination was accomplished in 917 (82%) procedures. The most frequent reason for inadequate evaluation was the presence of dense intraabdominal adhesions from previous surgery. We observed 105 (9.4%) minor complications and 20 (1.8%) major complications including one death following hemorrhage from liver biopsy. Major complications included abdominal wall hematoma, perforated abdominal viscus, hemoperitoneum, bleeding from liver biopsy, and respiratory depression. We observed a trend to decreased use of laparoscopy. Ascites of unknown origin and certain specific situations in patients with chronic liver disease remain as major indications for this diagnostic technique.

Serum C(3) (beta(1C)/beta(1A)) has been measured in normal individuals and the range found is in agreement with findings of other authors (85-370 mg/100 ml). In 18 patients with acute hepatitis and massive necrosis serum C(3) was consistently reduced to below 50% of normal. In other patients with acute hepatitis the serum C(3) concentration was normal. In the majority of the 150 patients with chronic liver disease serum C(3) concentration was normal. However, 10 patients (six with active chronic hepatitis, four with cryptogenic cirrhosis) had hypocomplementaemia. The reason for the depression is not clear but could reflect either decreased synthesis or increased consumption, or a combination of the two.

Coagulation studies were carried out on 30 patients with chronic liver disease. The clotting defect was complex and involved factors V, VII, IX (Christmas factor), and prothrombin. Some patients showed a significant depression of factor IX in the presence of a normal one-stage prothrombin time. Thrombotest was found to be a good indicator of factor IX deficiency in this group of patients and may be of use as an additional liver function test. The screening of patients with liver disease for surgery or liver biopsy should assess the coagulation factors involved in both intrinsic and extrinsic thromboplastin generation.
