The hepatoma-specific band of serum gamma-glutamyl transferase II (GGT II) and other three markers were evaluated in 77 patients with primary hepatocellular carcinoma (PHC). The positive rate of GGT II (87%) was much higher than that of the increased alpha-fetoprotein (AFP greater than or equal to 400 ng/ml, 54.5%), the increased alpha-1-antitrypsin (AAT greater than or equal to 400 mg/dl, 64.9%) and alkaline phosphatase isoenzyme I (ALP I, 13.0%). In patients with AFP less than 400 ng/ml, the positive rate of GGT II was 95.2%, higher than that of ALP I (22.8%) and AAT (60.0%). The positive rate of GGT II was positively correlated to the volume of PHC (r = 0.324, P less than 0.05), but even in patients with small PHC (less than or equal to 65 cm3), the positive rate of GGT II (78.6%) was higher than that of AFP (50.0%) and AAT (28.6%). The ALP I positivity was only seen in patients with larger PHC. Follow-up study showed that GGT II, like AFP, might occur before liver tumor could be detected by B-mode ultrasonography and computerized tomography. Therefore, GGT II is a valuable marker of PHC, especially in patients whose AFP was negative or slightly increased; GGT II may be useful for relatively early diagnosis of PHC.

The authors reported on a three month long EPREX (human recombinant erythropoietin) therapy of 5 hemodialysis patients for the treatment of their anemia. The drug was administered in bolus form 2 or 3 times a week after dialysis in a dose of 50 to 150 IU/bodyweight increased gradually in every (or every second) week. Hgb ad Htk values were determined once a week while erythrocyte, leukocyte, thrombocyte and reticulocyte count once a month. Serum iron, TIBC, serum ferritin, BUN, serum creatinine, urea, serum ions, liver function assays, serum lipids and amylase were also established. Hgb, Htk levels and reticulocyte count have significantly increased in the 4th week of treatment already, severe anemia ceased with improved appetite, general condition and physical strength. Serum urea and LDH levels significantly increased while SGOT decreased. No significant change in leukocyte and thrombocyte count, serum Na, K, Ca, P, Cl, BUN, creatinine, total protein level, serum albumin, bilirubin, alkaline phosphatase, GGT, GPT, amylase and blood sugar as well as serum lipid level were observed. No adverse reactions occurred during the treatment. After the three gradually decreased and within 6 weeks they had to be transfused again. In three patients the need for transfusion has significantly grown after the treatment. The authors consider EPREX a highly efficient drug in the treatment of anemia in dialysis patients.

The systemic administration of interleukin-2 (IL-2) can lead to significant antitumor responses in some patients with metastatic cancer in whom standard therapy has failed. A limitation of this immunotherapy is the toxicity associated with IL-2 infusion. To assess toxicity, we determined aspartate aminotransferase (AST; EC 2.6.1.1), alanine aminotransferase (ALT; EC 2.6.1.2), gamma-glutamyltransferase (GGT; EC 2.3.2.2), lactate dehydrogenase (LD; EC 1.1.1.27), alkaline phosphatase (ALP; EC 3.1.3.1), creatine kinase (CK; EC 2.7.3.2), total bilirubin (TBI), direct bilirubin (DBI), creatinine, urea nitrogen, and C-reactive protein in serum from 21 patients before and during five consecutive days of IL-2 treatment. Ten patients were followed for an additional five days after the end of IL-2 therapy. The IL-2 infusion caused liver toxicity and prerenal azotemia, as evidenced by significant increases (P less than 0.05) of all analytes except CK by day 1. There was a progressive increase in the results (except CK) for these tests until IL-2 treatment was stopped. Seven tests related to liver function (AST, ALT, GGT, LD, ALP, DBI, and TBI) showed increases, but the test results indicated significant improvement and moved toward the baseline value five days after the end of IL-2 therapy. Concentrations of creatinine and urea nitrogen in serum were normal three days after the cessation of IL-2 therapy.

Forty-two patients with small cell lung cancer were treated with a combination of carboplatin, ifosfamide and etoposide. Vincristine was given on day 14 of each course, the courses being repeated every 28 days for a maximum of six. Thoracic radiotherapy was given 4 weeks after the last course of chemotherapy but no prophylactic cranial radiotherapy was administered. Thirty patients had clinically limited state disease, the remaining patients having contralateral neck lymphadenopathy and/or pleural effusions. Elevated enzyme levels (alkaline phosphatase, LDH, ALT, GGT) were noted in 69% of patients. Twenty-four patients (57%) achieved a complete response (CR) when assessed one month after the end of treatment. A further 21% of patients had a partial response (PR). Median duration of CR was 14 months and of PR 8 months. Cerebral metastases were the sole site of relapse in 13% of the CR patients. Myelosuppression was severe with a median nadir of neutropenia of 0.2 x 10(9) cells 1-1. However, 74% of the patient group received all six courses of chemotherapy and only 16 courses (7%) were delayed because of toxicity. There were three deaths associated with treatment-related neutropenia. The median survival of the total group was 14 months, with an actuarial 2 year survival of 37% and a minimum follow-up of 18 months. [A recent analysis, March 1989, demonstrated a 33%, 2 year actual survival.]

To establish the prevalence of liver enzyme alterations in the course of serious infections of diverse origin, 112 patients were studied retrospectively for the levels of GOT, GPT, LDH, GGT, alkaline phosphatase (FA) and bilirubin (BIL). Cases in which the values might be altered due to causes other than the infectious process were previously excluded. The prevalence of affectation of each of the parameters was the following: GGT, 39.1%; LDH, 33.3%; FAL, 30.1%; GOT, 29.5%; GPT, 24.8%; BIL, 18.3%. Seventy percent had at least one of these values changed. No significant differences were found in the incidence or intensity of the analytic alterations in function of the origin of the of infection, which suggests that these modification are nonspecific. Bilirubin levels were found to be significantly higher in the patients who died. On realizing the linear correlation analysis between the diverse parameters studied, a good correlation was found between them, suggesting a common pathogenetic mechanism.

A considerable body of evidence suggests that the nephrotoxic potential of aminoglycoside antibiotics may be associated with the degree of membrane binding and subsequent membrane damage in the renal tubules. In this study, we isolated functional basolateral and luminal membrane vesicles from rat renal cortex, incubated each membrane type in the presence of 1 mM concentrations of either neomycin, netilmicin, gentamicin, hydroxygentamicin, or amikacin, and monitored the activities of the marker enzymes alkaline phosphatase (ALP) and lambda-glutamyltransferase (GGT) (luminal) or ouabain-sensitive Na+,K+-ATPase (basolateral) to determine if there were any selective drug-related alterations of enzyme activities. While none of the five aminoglycosides had any substantive effect upon enzyme activities of luminal vesicles, all five drugs inhibited the basolateral marker enzyme. Neomycin produced the greatest inhibition, hydroxygentamicin and amikacin the least, and gentamicin and netilmicin were intermediate in the inhibition of the enzyme. These results are in accordance with the known relative nephrotoxicity of these same drugs and indicate the usefulness of isolated renal membrane vesicles for in vitro toxicological studies of novel aminoglycosides.

Some biochemical, pathohistological and ultrastructural changes in liver after the action of single intraperitoneal administration of furosemide (Furantryl-Pharmachim) in a dose of 300 mg/kg of body mass were studied in male white rats of Wistar strain. The results from the performed experiments established increased activity of serum enzymes GOT, GPT, GGT, alkaline phosphatase as well as low values of serum cholinesterase. Pathohistologic and electron microscopy examination discovered liver damage with typical congestive changes mainly--manifested local erythremia and a reduced fluid content of the blood in the liver with blockage in the sinusoidal pole of hepatocytes; there were also focal micronecrosis, considerable reduction of glycogen and slight centrolobular steatosis. The possibility is discussed for usage of hepatotoxicity, induced by furosemide, in examining the effects of some drugs with potential hepatoprotective activity.

We have studied in rats the influence of renal ischemia on urinary excretion of three brush border membrane enzymes (gamma glutamyl transferase, alkaline phosphatase and leucine aminopeptidase) and of a lysosomal one (N-acetyl-B-D-glucosaminidase). Urines were collected over 24 hours periods during three days before and after a 45 minutes renal artery clamping. Urinary GGT, PAL and LAP excretion were significantly increased on the first day after renal ischemia, but returns to normal values on the second day. Urinary NAG activity increases on the first day, but contrary to the latter enzymes, reached to normal values only on the third day. Enzymuria seems to be a useful marker of tubular injury occurring after a temporary renal ischemia in the rat.

A double-blind study was done giving 10 mg of copper/day as copper gluconate or placebo capsules for 12 wk. The seven subjects receiving copper gluconate had no change in the level of copper in the serum, urine, or hair. There was also no change in the levels of zinc or magnesium. There was also no significant change in levels of hematocrit, triglyceride, SGOT, GGT, LDH, cholesterol, or alkaline phosphatase. The side effects of nausea, diarrhea, and heartburn were the same in the subjects receiving copper gluconate and subjects receiving placebo capsules.

Health examinations of 108 workers exposed to vinyl chloride monomer (VCM) at a Japanese chemical plant were carried out in 1979. The polymerization of vinyl chloride was started at the plant in 1949. In this study, the highest concentration of VCM in autoclaves was determined to be 250 ppm in 1961. However, the workers at the plant had been exposed to higher concentrations of VCM several times before 1960. More recent VCM exposure was considered negligible. Examinations assessed data on age, height, weight, obesity index, sake consumption, VCM exposure concentration, latent period, cumulative exposure, ICG (indocyano green test), serum bilirubin, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), A1-P (alkaline phosphatase), GGT(gamma-glutamyl transpeptidase), ZTT (zinc turbidity test), LDH (lactate dehydrogenase), cholesterol, TTT (thymol turbidity test), A/G (albumin globulin ratio), and thrombocytes. Variation in VCM exposure did not affect tests of pigment excretion from the liver, such as ICG; thrombocytes; and enzyme activity (such as GPT); nor bilirubin or flocculation reaction in serum.
