The usefulness of hepatic artery infusion (HAI) with floxuridine is limited by the severe biliary and hepatic toxicity of floxuridine. This prompted the SAKK to evaluate the effectiveness, toxicity and feasibility of HAI with fluorouracil (FU) and mitomycin (MMC) administered by an external portable pump. Of 28 patients treated, partial responses were obtained in 14 (50%, 95% confidence interval: 30% to 70%) and stabilization in 11 (39%, 21% to 60%), for a median duration of 12.6+ months. Median survival was 19.5+ months. Grade I-II toxicity (WHO) consisted of nausea (46%), leucopenia (32%) thrombocytopenia (21%) and abdominal discomfort (25%). Two patients developed gastro-duodenal ulcers and two others grade III leucopenia. No life-threatening side effects, especially no sclerosing cholangitis or chemical hepatitis, were observed. In conclusion, HAI with FU and MMC is a valid alternative to floxuridine HAI in metastatic colorectal cancer confined to the liver.

Intra-arterial hepatic chemotherapy (IAHC) with adriamycin (ADM) has not increased its therapeutic index. For our preclinical studies, we selected pirarubicin (THP), an ADM derivative with faster cellular uptake. In rabbits with VX2 tumor in the liver we compared plasmatic and cellular pharmacokinetics of ADM and THP after i.v. and IAH therapy. For ADM, there were no differences in plasma and heart concentrations, with only a slight increase in tumoral levels after IAH compared to i.v. administration; on the other hand, with IAH THP, there was important reduction in systemic exposure with a major increase in tumoral drug distribution. In the phase I study, involving nine patients with implanted catheters, the starting dose of THP was 30 mg/m2 with a 10 mg/m2 intrapatient escalation every 3 weeks in the absence of toxicity. Pharmacokinetics were compared for i.v. and IAH administration in seven patients. The limiting toxicity was neutropenia and the maximal tolerated dose (MTD) ranged from 50 to 110 mg/m2. Moderate nausea-vomiting (grade 1-2) and alopecia (grade 1) occurred at the MTD. No arterial occlusion, gastroduodenal ulcer, hepatitis, or sclerosing cholangitis were seen. In the phase II study, in colorectal cancer patients (CRC) with metastasis confined to the liver, patients were enrolled until June 1990. THP (40 min infusion every 3 weeks) was initiated at 60 mg/m2 with 10 mg/m2 increment until grade 2 hematotoxicity. The median MTD was 85 mg/m2 (range of 60-120 mg/m2), and the median number of cycles was 7 (range of 2-11) with cumulated doses from 180 to 1,030 mg/m2. Grade 2-4 neutropenia was reached in 15 patients. Other toxicities included two arterial occlusions, one episode of gastritis, but no hepatic toxicity and no heart failure. Antitumor effect (in 18 patients) included 1 CR, 5 PR, 3 MR, 6 NC, and 3 PD. The median survival was 18+ months and 1-year survival was 73% +/- 12%. Seven patients had extrahepatic progression at this time. In conclusion, besides 5-FU or Fudr, THP is active in IAHC (probably in relation with high local extraction) on CRC liver metastases usually unresponsive to ADM. It can be given in an outpatient setting with minimal toxicity.

The authors report a case of toxic hepatitis in a woman of 22 years of age in the third trimester of her first pregnancy treated by methyldopa for hypertension of pregnancy which was diagnosed at 33 weeks of amenorrhoea. The prodromal symptoms were mild and consisted of nausea, vomiting and rise in temperature and this phase was associated with febrile jaundice without pruritus and it was only associated with coagulation disorders in the third stage of labour. This was a case of mixed cytolytic hepatitis (ASAT x 3N) and cholestasis (x 1.5N). The outcome was fatal. The patient died three days after delivery following haematemesis and renal failure as well as hepatic encephalopathy. The main diagnostic feature was acute hepatic stasis in spite of the absence of pruritus and the presence of a raised temperature after hematolytic, viral and obstructive causes had been eliminated. Histology confirmed that there was toxic hepatitis. This aetiology was suggested by the timing of the symptoms after MD (methyldopa) had been taken. Elkington described methyldopa hepato-toxicity in 1969. Fatal cases in the literature were in patients who were over 40 years of age. Methyldopa is used in pregnant women because of its safety as far as the fetus is concerned. Mechanism by which it causes toxic hepatitis is a combination of abnormal metabolism (the cytochrome P450 chain produces an antigen) and an immune reaction in response to this antigen and these explain why such severe and potentially fatal forms of the condition exist.(ABSTRACT TRUNCATED AT 250 WORDS)

A patient with systemic lupus erythematosus presenting abdominal pain, nausea, vomiting and severe mucocutaneous vasculitis had significant elevation of serum amylase and hepatic enzymes levels during a flare-up of the disease. Clinical and laboratory alterations disappeared after therapeutic increase of corticosteroids given to the patient a fact that suggested etiologic correlation between systemic lupus erythematosus, hepatitis and pancreatitis.

A Phase I study of recombinant interferon-gamma (rIFN-gamma) was conducted to determine the toxicity and pharmacokinetics of this lymphokine in acquired immunodeficiency syndrome (AIDS) patients with Kaposi's sarcoma (KS). Sixteen patients with AIDS/KS were entered into a fixed-dose trial at either 0.001, 0.01, 0.1, or 1.0 mg/m2 of rIFN-gamma. rIFN-gamma was initially administered either as a single 24-hr continuous iv infusion or as a single im injection, followed 4 days later by a 10-day course of daily therapy by the same route. Following a 1-week washout period, this sequence of administration was then repeated, with the drug given by the alternate route. Pharmacokinetic analysis of the 1.0-mg/m2 group revealed that peak serum levels of up to 153 U/ml occurred 2-4 hr after im injection and that steady-state levels of up to 40 U/ml were reached approximately 7-12 hr after beginning iv infusion. Dose-related toxicities in this trial included fever, headache, fatigue, nausea, and hepatitis, all of which were most severe at the two highest doses. Dose-dependent depression of the total white blood-cell (WBC) count, affecting both granulocytes and lymphocytes, was the most common laboratory abnormality. Natural killer (NK)-cell activity was slightly enhanced at a dose of 0.1 mg/m2 but suppressed at 1.0 mg/m2 of drug; monocyte-mediated cytotoxicity, in contrast, was significantly increased only at the highest dose. No dose-related changes were noted in KS lesions, HLA-DR expression by peripheral blood mononuclear cells, lymphocyte blastogenesis, or the ability to culture cytomegalovirus (CMV) from body fluids. We conclude that a maximally tolerated dose (MTD) for this drug is in the range of 0.1-1.0 mg/m2 and that at least modest evidence of systemic immunomodulation may be seen when rIFN-gamma is given at doses at or near this MTD.

The authors reviewed the liver histopathology and the clinical features of eight patients with liver metastases from colorectal cancer who were treated by hepatic arterial infusion chemotherapy (HAIC) via an implantable pump (Infusaid). Before HAIC, these patients had no evidence of hepatitis, and results of liver biopsies performed on three patients showed only minor morphologic alterations. All the liver tumors responded to HAIC, but all patients developed hepatitis. Clinical findings included nausea, vomiting, abdominal pain and jaundice. Serum transaminases, alkaline phosphatase and bilirubin levels were increased. Clinical observations suggested that 5-fluoro-2'-deoxyuridine (FUDR), the predominant drug given, was the hepatotoxic agent. Toxic effects were hepatocyte necrosis, steatosis, cholestasis, central vein sclerosis, and alterations in the portal triad. In addition, central vein lesions like those in veno-occlusive disease, and micronodular cirrhosis resembling that induced by alcohol, were encountered. Although individual susceptibility to FUDR appeared to vary, portal triad fibrosis was present in all eight cases and, together with central vein sclerosis and cirrhosis, appeared to be related to the dose and duration of HAIC.

A phase II study with cyproterone acetate (CPA) was done as the primary treatment in female breast cancer patients. Twenty-three patients, mean age 64 years, range 52-75 years, were entered and treated with CPA 400 mg daily. Twenty patients were evaluable and responses were sparse. There was one partial and one complete remission, 17 patients were stable and one patient progressed within 3 months. Side-effects were frequent: five patients complained of nausea, three had severe weight loss, one suffered from depression and seven showed disturbed liver function tests. Six patients had to stop treatment for side-effects, while two other patients were taken off treatment because they developed an acute necrotizing hepatitis. The hepatitis recovered after drug withdrawal in both patients. The serum levels of CPA, cortisol, androstenedione, DHAS, LH, FSH and prolactin were measured during CPA treatment. The levels of cortisol and androstenedione did not change, while LH, FSH and DHAS were suppressed. The DHAS showed an inverse relation to serum CPA concentrations. The prolactin levels rose uniformly. The therapeutic effect of CPA in postmenopausal patients with advanced breast cancer is disappointing, and inferior to that of other progestins. Side-effects are frequent, possibly as a result of the high dosage used in this study. The hormonal changes are different from those of other progestins, which may explain the different efficacies.

Differential diagnosis of viral hepatitis begins with a check for darkened urine and bile in the urine. These hallmarks of conjugated hyperbilirubinemia immediately rule out prehepatic liver disease. Next, studies are done for the elevated transaminase levels that are characteristic of hepatitis infection, and a thorough history is taken to rule out drug- and toxin-induced hepatitis that may mimic acute viral hepatitis. Elevated alkaline phosphatase is a good marker of cholestasis. Ultrasonography can clarify this diagnosis. The classic presenting symptoms of viral hepatitis are jaundice, nausea, vomiting, malaise, anorexia, and dull right upper quadrant pain. However, serologic studies are needed to detect the presence of specific viral agents.

Flecainide was given to a patient in a dose of 150 mg twice daily to convert a newly developed atrial fibrillation; concomitant therapy was unchanged. After the fourth dose the patient complained of upper abdominal pain and nausea. GOT and GPT, normal at admission to the hospital, became markedly elevated and reached a maximum of 960 IU/I (GOT) and 993 IU/I (GPT) one day later, although the enzymes which indicate cholestasis remained at a normal level or did not increase. On the assumption of a drug-induced allergic reaction, flecainide was withdrawn, after which liver enzymes rapidly returned to control values. Although neither a reexposition with flecainide nor a liver biopsy was obtained, a flecainide-induced hepatitis seems probable.

Dapsone (4-4-diaminodiphenyl-sulfone) is a member of the sulfone group of antibiotics used in the treatment of leprosy and various dermatitidies and more recently employed in the management of local reactions to the bite of the brown recluse spider, Loxosceles reclusa. A dapsone hypersensitivity syndrome, consisting of fever, headache, nausea, vomiting, lymphadenopathy, hepatitis, hemolysis, leukopenia, and mononucleosis, has been described in patients treated with the drug for leprosy. A case report of the hypersensitivity syndrome occurring in a patient being treated with dapsone for a brown recluse spider bite is presented.
