1. Effects of chronic anticoagulant therapy in heart patients and anticonvulsant therapy in epileptics on gamma-glutamyl transpeptidase activity in serum were investigated. 2. The enzyme was elevated in 22% of 18 patients receiving anticoagulants. In these patients prothrombin time was also abnormally high. 3. 84% of 65 epileptics exhibited elevated gamma-glutamyl transpeptidase activity, 67% of which were not associated with elevated alkaline phosphatase or aspartate aminotransferase activities. In these latter cases, involvement of the liver was not apparent. 4. Possible relationships of anticonvulsant mediated enzyme induction or hepatic toxicity to elevated gamma-glutamyl transpeptidase activity in serum in epileptics is discussed.

Diabetes mellitus is satisfactorily controlled in the rat by hepatic implantation of isolated, isologous pancreatic islets. The transplanted islets appear to be viable for at least 6 months after implantation, and hepatic function studies (serum bilirubin, alkaline phosphatase, glutamic-oxalacetic transaminase, prothrombin time) and microscopic examination indicate that they do not interfere with hepatic function.

In 90 patients with known extra-hepatic malignancy the liver was examined for metastases. The diagnostic value of clinical information, blood examinations, 99mTc scintiscan, and laparoscopy for the diagnosis of the liver metastases was evaluated. Clinical data (age, sex, time since onset of symptoms and localisation of primary tumor) are of no diagnostic value. The most reliable blood tests are alkaline phosphatase (AP) and GOT. The probability of liver metastastases rises with increasingly abnormal values of AP and GOT. However, the probability is not much greater in cases with highly abnormal values than in cases with only moderate elevation of AP and GOT. Diagnostic accuracy of AP is optimal by using a cutoff point of 76 U/l (sensitivity 79%, specificity 64%). Bilirubin, prothrombin time, haemoglobin and blood sedimentation rate are of very little value. Combinations of AP with these blood tests does not improve diagnostic accuracy. Therefore, it is not useful to determine more blood tests than AP alone. Informed reading of liver scans has a specificity of 75% and a sensitivity of 91%. Blind reading of scans has a sensitivity of 94% and a specificity of 95%. This diagnostic accuracy cannot be improved by additional blood tests. Laparscopy has a sensitivity of 85% and a specificity of 95%. Scanning and laparoscopy are complementary methods. When optimal diagnostic accuracy is required both methods should be used.

The effect of corticosteroid (or ACTH) therapy on 4 patients with idiopathic granulomatous hepatitis is described. All patients presented with spiking fever and chills and none had jaundice. Only 1 patient had an enlarged tender liver and 3 had splenomegaly. The erythrocyte sedimentation rate was increased in all cases while the white blood cell count was typically normal. Impairment in liver function was insignificant and consisted of a mild elevation of SGOT and alkaline phosphatase activities and prolonged prothrombin time. All patients presented a diagnostic challenge. The diagnosis was established by routine liver biopsies in 3 cases and by laparotomy in the 4th. The etiology could not be established. All patients reacted dramatically to prednisone (or ACTH) after failure of other therapeutic regimens. The disease has, however, been present for 5 years in 1 patient and 10 years in another, Relapses occur after cessation of therapy.

A long term study was carried out to determine the possible toxic effects of therapeutic doses of a suspension of benorilate on bone marrow, liver and kidneys in 33 patients with rheumatoid arthritis. 14 were male and 19 femal patients. 11 of the male and 14 of the female patients presented a positive rheumatoid factor. The duration of the treatment was first limited to 6 months. In 20 of the 33 patients duration of treatment was extended to 7 and 91/2 months. Three patients interrupted treatment after respectively 2, 3 and 5 months. Benorilate was given in a daily dosage varying from 6-8-12 g (as a suspension containing 40% benorilate). The following parameters were used to determine the effect of the drug on bone marrow: Hemoglobin, erythrocyte count, leucocyte count, thrombocyte count. Tests were done at regular intervals to determine a possible toxic effect on the kidney: urea nitrogen, uric acid, creatinine and urineanalysis were performed at regular intervals. To determine any possible hepatic toxicity, SGOT, SGPT, alkaline phosphatase and prothrombin time were done at regular intervals. On the basis of the laboratory results, no toxicity could be demonstrated in bone marrow, liver and kidneys when benorilate was given in therapeutic doses for the treatment of rheumatoid arthritis. Rare temporary abnormal laboratory values are not statistically significant and can be considered part of systemic involvement secondary to rheumatoid arthritis. The combination of the two active substances of benorilate decreases to a minimum on the one hand the above mentioned side effects and on the other potentiates the therapeutic and especially the analgetic effect. After resorption, the preparation is hydrolized in the plasma to acetylic salicylic acid and paracetamol. The hydrolysis takes place in the gastrointestinal tract which probably explains why the drug is so well tolerated.

A double-blind clinical trial with zinc sulfate, 0.2 g three times daily, and a placebo was performed in 30 patients with biopsy-proven alcoholic liver cirrhosis. The disease was in a stable phase, and none of the patients showed evidence of a decompensated liver function. Parameters of liver function, taste acuity, dark adaptation and of zinc and vitamin A metabolism were followed for six weeks. In the zinc-treated group of 16 patients, serum zinc rose from a normal mean value of 13.3 to 17.4 mumol/l, whereas the mean serum vitamin A level remained practically unaltered within the normal range, 1.89 at the entry and 1.83 mumol/l at the end of the study. Plasma prothrombin and serum alkaline phosphatase levels of the zinc group increased and serum bilirubin and serum carotene decreased significantly. The dark adaptation did not change, but the taste function was significantly improved during zinc treatment. The results indicate that zinc supplementation causes alleviation of certain abnormalities of cirrhotics, which deserves further attention.

The effects of three widely spaced levels of bacterial contamination of reagent water on several chemistry, radioimmunoassay, and coagulation procedures were studied. These included determinations of lactate dehydrogenase, creatine kinase, aspartate transaminase, alkaline phosphatase, blood urea nitrogen, total protein, thyroid-stimulating hormone, digoxin, thrombin time, activated partial thromboplastin time, and prothrombin time. Statistical analyses included calculations of means and coefficients of variation, and analysis of variance, as well as correlation coefficients for test results versus logarithm of bacterial contamination. Statistically and clinically significant differences occurred together only for an elevated level of creatine kinase.

In a multicentre, cooperative study into the treatment of extensive psoriasis with a new aromatic retinoid (Ro 10--9359) trichogram, liver function tests and the light erythema threshold were investigated. In some of the patients hair loss occurred, usually in the fifth to eighth week after a total dose of 1.9 g retinoid. In all cases this improved an average of six weeks after dose reduction or cessation of treatment. The trichogram in 27 patients showed a diffuse toxic hair loss. In 70% the effluvium was telogenic, in 22% telogen-dystrophic. GPT, GOT, alkaline phosphatase and prothrombin index showed no significant alterations during retinoid treatment. However, in individual cases there was a rise in GOT and GPT up to 80 U/l. Furthermore there was a statistical tendency in rising bilirubin levels. Finally there was no evidence for an increase in light sensitivity after three weeks of retinoid treatment. Measurement of the erythema threshold showed rather more a reduction in light sensitivity under treatment.

The observation of a non-metastatic reactive hepatopathy associated with a hypernephroma in a 39-year-old man who had had fever for 4 months led to a review of the literature and an analysis of basically three aspects of the disorder: a) The various manifestations of carcinoma of the kidney, which include a large number of paraneoplastic clinical symptoms (polycythemia, anemia, prolonged fever, hypercalcemia, hypertension, nefropathy, loss of salt, peripheral neuropathy, and amyloidosis); b) an alteracion of hepatic function known since 1961 which is characterized by an abnormal retention of sulfobromophthalein, increase of alkaline phosphatase, prothrombin decrease, dysproteinemia with hypoalbuminemia, and alpha2-globulin increase. It may or may not be accompanied by enlargement of the liver. c) Criteria of operability of the primary tumor.

Admission serum triiodothyronine (T3) values in 124 patients hospitalized for alcoholic liver disease were correlated with clinical and laboratory indices of liver function and commonly used determinants of thyroid function. Patients with low admission serum T3 levels had significant alterations in serum albumin, bilirubin, prothrombin time, and alkaline phosphatase associated with clinical signs of portal hypertension and collateral circulation, with little difference in serum glutamic-oxaloacetic transaminase, serum gamma glutamyl transpeptidase, or serum ornithine carbamyl transferase. This group also had a significant decrease in free T3 index despite an increase in T3 uptake; the slight reduction in total thyroxine (T4) was associated with an increase in free T4 index and no change in serum thyrotropin (TSH). For patients with alcoholic liver disease, low admission serum T3 and free T3 index values when accompanied by normal serum T4, free T4 index, and TSH levels appear to be indicative of severe liver dysfunction and increased mortality risk.
