A 15-year old Black teenager came to a clinic at the University of Alabama's School of Medicine in Tuscaloosa requesting oral contraceptives (OCs). The physical examination indicated that she was in good health and the physician prescribed an OC (1 mg norethindrone and .035 mg ethinyl estradiol). 21 months later she returned complaining of yellow eyes for 3 weeks. The oral mucosa was also jaundiced. She had considerably high levels of bilirubin and alkaline phosphatase. She had no hepatitis virus antibodies. 5 months later she returned for the physical examination required to renew the OC prescription. She did not have jaundice at this time. 10 months later she complained of malaise and muscular pain. Her alkaline phosphatase level was high, but her bilirubin level was normal. She had mild hepatosplenomegaly without focal defects. After reviewing her medical records, the physician diagnosed intrahepatic cholestasis and discontinued her OC prescription. Liver function tests were normal within 3 months. 14 months later, she returned complaining of malaise and reported taking OCs obtained at another clinic 3 months earlier. The physician advised her about the complications of OCs and about other contraceptive methods. The same physician also examined a 32-year-old Black woman who had intermittent epigastric and right-upper quadrant abdominal pain for 2 weeks. Eating worsened the pain, which lasted for up to 15 minutes. She had used an OC for 12 years. Ultrasound revealed a 4.2 cm hypoechoic mass in the left upper lobe of the liver. The physician discontinued the OCs. The tumor regressed over 12 months. Active liver disease is a contraindication to OC use. Women who had cholestatic jaundice while pregnant or have first degree relatives with cholestatic jaundice of pregnancy should not use OCs. Physicians may introduce OCs to closely monitored women with a history of liver disease whose liver function tests are normal. Women with a family history of biliary excretion defects should not use OCs.

The impact of dengue on liver function was studied by biochemical tests on 125 male and 145 female patients diagnosed with this disease during an outbreak that extended from November 1987 to December 1988. Abnormal levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, alkaline phosphatase, and gamma-glutamyl transpeptidase (G-GT) were observed in 93.3%, 82.2%, 7.2%, 16.3% and 83.0% of the patients, respectively. The elevation of transaminases was mild to moderate in most cases, but was 10-fold greater than the normal upper limit for AST and ALT in 11.1% and 7.4% of the patients, respectively. Initially, the level of AST was greater than that of ALT, increasing to maximum levels nine days after the onset of symptoms, then decreasing to normal levels within two weeks. Results of the biochemical tests did not differ significantly between the cases with and without hepatitis B or hepatitis C virus infection, but significantly higher elevations of AST, ALT, and G-GT were observed in patients with episodes of bleeding. Liver biopsies of two patients showed features of lobular hepatitis. Of the five fatal cases, three died of hepatic failure. It is concluded that dengue fever may cause hepatic injury and transaminase elevation similar to that in patients with conventional viral hepatitis. In epidemic or endemic areas, dengue fever infection should be considered in the differential diagnosis of hepatitis.

The examination of 5-cholestasis indicating enzymes was carried out in patients with viral B hepatitis. The changes in activity of such enzymes: alkaline phosphatase, its liver isoenzyme, gamma glutamyltranspeptidase, 5'nucleotidase, leucine aminopeptidase and alanine aminopeptidase were estimated as for being useful in discovering the states of cholestasis. Already in the first week of observation all examined enzymes showed the highest level of activity, only in the case of FZ and FW, however the difference between the patients with and without cholestasis were markedly static. In the following weeks the differences in average activities between group with and without cholestasis were present in the case of 5'N and LAP. The activity of GGTP and AAP were high in both groups of patients. And so alkaline phosphatase is the enzyme which discovers the states of cholestasis in viral B hepatitis quickly and markedly.

Pneumocystis carinii infection of the liver is being reported with increasing frequency in patients with acquired immune deficiency syndrome (AIDS). The clinical picture typically resembles hepatitis. We report such an occurrence in a patient with persistent elevation of alkaline phosphatase and gamma-glutamyl transpeptidase with relatively normal transaminases who was found to have P. carinii on antemortem liver biopsy. The differential diagnosis of abnormal alkaline phosphatase and gamma-glutamyl transpeptidase in patients with AIDS should include P. carinii.

Triggered by a case of ischaemic hepatitis (shock liver) in a patient with severe respiratory insufficiency, we tried to gather information about clinical characteristics and incidence. To our surprise, this information could be found neither in major critical care, medical or gastroenterology textbooks nor in textbook indices or works on differential diagnosis. From Sept. 1989 to May 1990 we studied all possible cases of ischaemic hepatitis in a 390 bed general hospital, to establish incidence. Using computerised data from the clinical chemistry laboratory, all patients with grossly abnormal liver function tests were identified. In this nine-month period 27 adult patients had a peak ALAT level of > 500 U/l: 8 of these suffered from ischaemic hepatitis, using the criteria described by Gibson et al. In another 5 this diagnosis was suspected but could not be ascertained before death (30% and 18% of all cases). In all these cases ASAT, ALAT, LDH levels were 8-100 times normal, but bilirubin, alkaline phosphatase, gamma-glutamyl transferase and prothrombin time were only slightly abnormal. With correction of the underlying disorder enzyme levels returned to normal very rapidly, in 5-10 days. Ischaemic hepatitis could easily be distinguished from other causes such as alcoholic, viral or drug-induced hepatitis. Ischaemic hepatitis was the most frequent cause of severely elevated ASAT, ALAT and LDH in hospitalised patients. The diagnosis can easily be made on clinical characteristics and the typical biochemical pattern. An elaborate work-up or invasive procedure is redundant. Prognosis per se is excellent but depends on the underlying disorder.

Activities of arginase, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase were determined in sera obtained in a group of healthy women, women with verified carcinoma of the breast, benign mastopathy, a group of patients with carcinoma of various organs and a group of patients with acute viral hepatitis. Preoperative values of serum arginase activity in patients with breast carcinoma were up to 4-fold those found in healthy women. Sensitivity of the test was 86%. After the surgery, the activity decreased abruptly during the first week and normalised within 15-30 days. In benign diseases of the breast, the activity of arginase was normal. Serum arginase activity is raised in both benign and malignant liver diseases, however, the quotients alanine aminotransferase/arginase, aspartate aminotransferase/arginase and alkaline phosphatase/arginase differ significantly. Thus, use of alanine aminotransferase/arginase quotient implies a high degree of confidence in differentiating between increased arginase activity in mammary carcinoma (alanine aminotransferase/arginase = 0.572 +/- 0.278) and high arginase activity in hepatitis (alanine aminotransferase/arginase = 12.226 +/- 1.822).

The present study examined the preventive effects of green tea extract on D-galactosamine (GalN)-induced hepatic injury in rats, an animal model of viral hepatitis. A single i.p.-injection of GalN (700 mg/kg) to male Wistar rats caused fulminant hepatitis by 48 hr as assessed by marked increases in the serum aspartate aminotransferase (GOT), alanine aminotransferase (GPT) and alkaline phosphatase (ALP) activities; decreases in the serum protein and cholesterol levels and the amount of liver microsome P-450; and marked changes in organ weights. The lecithin: cholesterol acyltransferase (LCAT) activity markedly increased at 8 hr and markedly decreased at 24 hr after the GalN injection. In the experiment, animals were orally administered green tea extract at doses of 50, 100 or 200 mg/kg five times each before and after the GalN injection. Treatment with green tea extract significantly prevented the increases in the GOT, GPT and ALP activities in a dose-related manner. It also significantly prevented the decreases in serum albumin and total cholesterol, although not in a dose-related manner. A tendency to prevent the increase in LCAT activity and the decrease in liver microsome P-450 was also noted. Little effect was found on the other abnormal changes in the serum lipids and proteins and the organ weights. These results suggest that green tea may have an ameliorating effect on hepatic dysfunction.

Recent reports of transmission by intravenous gamma-globulin preparations of A, B, C and non-A non-B hepatitis (NANBH), including several cases that progressed to severe liver damage and death, have raised concerns about the safety of intravenous gamma-globulins. To assess this issue 15 patients treated with high-dose "intravenous immunoglobulin" (IVIG) for Graves' Ophthalmopathy had serial determination of glutamic pyruvic transaminase (GPT), glutamic oxalacetic transaminase (GOT), gamma glutamyltranspeptidase (gamma-GT), alkaline phosphatase and bilirubin that were performed regularly at interval of 3 weeks during IVIG treatment and 6 months after the end of the treatment. Hepatitis A, B, C and HIV markers were determined before, during and 6 months after the end of the treatment. The standard dosage was 400 mg per Kg body weight IVIG (3 cycles of 5 days and 12 of 1 day, every 21 days). Transient minor elevations were observed for GPT, for GOT, for gamma-GT and alkaline phosphatase. None of the elevations were considered indicative of NANBH or of any chronic hepatic disease. Transient presence of hepatitis A, B and C antibodies were observed in 6 patients. All patients remained negative for hepatitis B antigens throughout the study. HIV antibodies resulted always negative in all patients. In conclusion this study suggests the hepatitis and HIV safety of IVIG.

It is not known whether the histopathology of the liver allograft can be predicted from biochemical measurements in serum with the same confidence as in the native liver. To answer this question we compared the histopathological diagnoses in 170 biopsy specimens from 70 adult transplant recipients obtained during the first 180 days, with the concentrations of the serum bilirubin and the activities of AST, ALT and alkaline phosphatase measured at the same time. The most frequent diagnosis was cholestasis (n = 45), which was mild, moderate or severe and which may have been complicated by rejection (n = 28) or ischemia (n = 14). Hepatitis (n = 14), ischemia with rejection (n = 6) and spotty focal necrosis (n = 6) were diagnosed less frequently. Fifteen biopsy specimens were reported as histopathologically normal. In general, biochemical measurements discriminated poorly between different histopathological diagnoses. The histopathologically normal liver often showed an abnormal pattern of enzymes and an increase in the serum bilirubin level. As a result histopathologically normal biopsy specimens were indistinguishable biochemically from those with hepatitis. When two pathological conditions were found to coexist (e.g., cholestasis with either rejection or ischemic necrosis, or ischemic necrosis with rejection), the effect on the serum biochemistry was usually not additive and in some instances returned the biochemical abnormalities toward normal. With the exception of the serum bilirubin level, which increased with the severity of uncomplicated cholestasis, we could not identify a specific pattern of biochemical changes corresponding to a given histopathological diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Administration of trimethoprim-sulfadiazine in a dog was associated with vomiting, inappetence, and icterus, and high values of alanine transaminase, aspartate transaminase, alkaline phosphatase, gamma-glutamyltransferase, and total bilirubin concentration. The clinical signs and biochemical abnormalities resolved after discontinuation of the treatment. Histologic examination of sections from a liver biopsy specimen revealed moderate, predominantly portal hepatitis with cholestasis.
