S-adenosyl-L-methionine (ademethionine) has been recently proposed as a therapeutic agent for the treatment of intrahepatic cholestasis (IHC), a syndrome that overlaps with many different types of liver diseases. To obtain a global assessment of the results of the therapeutic efficacy of this compound, a meta-analysis of 6 controlled clinical trials with ademethionine in the symptomatic treatment of IHC of liver diseases and pregnancy was carried out. The therapeutic response to ademethionine treatment, for 15 to 30 days, proved to be superior to placebo, as assessed by resolution of pruritus, normalisation or 50% improvement in serum total bilirubin, serum conjugated bilirubin, alanine aminotransferase, gamma-glutamyl transpeptidase and alkaline phosphatase. At present, the therapeutic effect of ademethionine should be regarded as symptomatic, but long term studies on the effect of drug administration on the course of the disease and survival are being performed.

Primary sclerosing cholangitis is a cholestatic disease of the liver characterized by progressive fibrotic inflammation and obliteration of the extra- and/or intrahepatic bile ducts. There is no effective therapy. We, therefore, studied the safety and efficacy of ursodeoxycholic acid in patients with primary sclerosing cholangitis with or without additional ulcerative colitis. In a 1-year ursodeoxycholic acid treatment period, which preceded the controlled study period, ursodeoxycholic acid was well tolerated in 22 of 24 patients with ulcerative colitis and in all three patients without ulcerative colitis. In two patients with ulcerative colitis the dose of 750 mg ursodeoxycholic acid/day led to diarrhea, but following reduction of the dose to 500 and 250 mg/day ursodeoxycholic acid was well tolerated. After 1 year of ursodeoxycholic acid treatment, 20 patients were randomly assigned to receive either ursodeoxycholic acid 750 mg/day or placebo. All of them finished a double-blind, placebo-controlled study period. During ursodeoxycholic acid treatment, the liver enzymes improved markedly. The difference in alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyltransferase between the placebo and ursodeoxycholic acid group was significant (p < 0.05). Following ursodeoxycholic acid treatment, pruritus and fatigue improved in half of the patients but the difference between the placebo and ursodeoxycholic acid group was not significant. According to the ethical guidelines, after 3 months of placebo treatment, the controlled study had to be discontinued because of a more than twofold increase of serum transaminases in 8/10 patients on placebo. After the end of the controlled study, all patients were continuously treated with ursodeoxycholic acid for up to 4 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Seven patients with primary biliary cirrhosis were treated with rifampicin administered for 2 weeks in a daily dose 450-600 mg. Due to the treatment the itch disappeared completely in 4 and decreased significantly in 3 patients. As shown by the antipyrine test, half-life and clearance of antipyrine returned to normal suggesting cytochrome P-450 induction as a result of hydroxylation activity. There was a tendency to lowering of bilirubin, cholesterol, alkaline phosphatase, asparagine--and alanine aminotransferase against an increase in gammaglobulins. The differences were, however, insignificant. Rifampicin tolerance was satisfactory.

Fifty subjects with acute uncomplicated falciparum malaria were treated orally with a new micronized formulation of halofantrine. The dose given corresponded to one-half the normal dose for the standard formulation. Parasitemia cleared in all subjects within 78 h. There was recrudescence of falciparum malaria in seven subjects after day 14. The mean +/- standard deviation clearance times of parasitemia and fever were 49.0 +/- 14.2 and 24.3 +/- 13.2 h, respectively. Other clinical symptoms related to malaria cleared within the first 3 days. Pruritus occurred in two subjects, back pain occurred in one subject, and diarrhea occurred in one subject; all of these symptoms were mild. Hematological and biochemical indices were not adversely affected by treatment except in five subjects in whom minor and transitory increases in aspartate aminotransferase and alanine aminotransferase were observed. Micronized halofantrine appears to be a safe, well-tolerated, and effective treatment for acute falciparum malaria in semiimmune patients.

In a multicenter, double-blind clinical trial in 1,968 inpatients 1 daily subcutaneous administration of LMW heparin plus 2 placebo injections or 3 x 5,000 IU unfractionated (UF) heparin was given for 10 (8-11) days. The primary end point was the incidence of proximal deep-vein thrombosis or pulmonary embolism. Patients were assessed during the study period for development of proximal deep-vein thrombosis by compression sonography at days 1 and 10 and for pulmonary embolism by scintigraphy in symptomatic patients. Aim of the study was to demonstrate the equivalence of both treatment regimens. A total of 1,968 patients were randomized to receive UF or LMW heparin. Of these, 378 patients were excluded during the study period, so that 780 patients on UF and 810 on LMW heparin were included in the efficacy analysis. Four primary end points were observed with UF and 6 with LMW heparin, demonstrating the equivalence of treatments (p = 0.012). Additionally, pulmonary embolism was suspected as the cause of death in 6 patients who died during the study (3 per treatment group). A higher frequency of death (n = 32) was observed in the LMW-heparin group (p = 0.02) particularly documented in a part of the centers. Safety analysis showed a higher frequency of local pruritus, local erythema and subcutaneous hematoma, a higher increase in plasma levels of triglycerides, total cholesterol, alanine aminotransferase and aspartate aminotransferase, and a decrease of antithrombin III in patients receiving UF heparin. A decrease in platelet count (values ranging between 40,000 and 80,000/microliter) was observed in 4 patients with UF and in none with LMW heparin. No severe thrombocytopenia was observed. Subcutaneous LMW heparin is as effective as UF heparin for prophylaxis of thromboembolism in bedridden, hospitalized medical patients.

Benign recurrent intrahepatic cholestasis (BRIC or Summerskill-Walshe-Tygstrup-syndrome) is a rare autosomal recessive form of liver disease, which usually becomes manifest in childhood. Characteristic are recurrent episodes of jaundice and itching of different duration. Number and duration of episodic attack and asymptomatic period develop individually. For diagnosis of BRIC following criteria are proposed: At least three episodes of severe jaundice and pruritus with biochemical evidence of cholestasis, normal intra-and extrahepatic bile ducts on cholangiography, absence of a factor known to produce intrahepatic cholestasis and symptom-free intervals of several months or years. Often the diagnosis of BRIC is made very late and patients have to suffer invasive investigations (explorative laparotomy). Because of the unknown pathophysiological mechanism there is no specific treatment. We report on a 53-year-old patient with jaundice, severe pruritus, vomiting, loss of hair and weight, extreme sleeplessness and intractable cough. At the onset of the attack an increase of serum bilirubin concentration and serum alkaline phosphatase was observed, whereas aspartate and alanine aminotransferase and gamma-glutamyltransferase were normal. Histological findings of liver biopsy revealed accumulation of bile plugs in bile canaliculi. The long-term follow-up of our patient confirms that the prognosis is good.

This study sought to identify any benefit of routine liver function tests (LFTs) in chronically ill, geriatric patients and to assess which patients require evaluation for abnormal LFT levels. A retrospective chart review was carried out on 268 consecutive patients (M:F = 1.2, mean age 77 years, range 61-98 years) presenting for acute care from a long-term care facility. All were without jaundice, right upper quadrant pain, pruritus, bruising, or signs of chronic liver disease. The degree of LFT abnormality (aspartate aminotransferase, alanine aminotransferase, total bilirubin, or alkaline phosphatase) during admission was compared to the clinical diagnosis at the time of discharge. The most common diagnoses were pneumonia, urinary tract infection, and peripheral or coronary disease in 186 (60%). Thirty-seven patients (14%) had elevated LFT levels on admission. The levels normalized within 2 days in 26 of these patients, 25 of whom had a history of vascular disease (96%). Of the 11 remaining patients, 4 had coexistent vascular disease (36%), and 5 had LFT levels twice normal (none with vascular disease) and underwent abdominal ultrasound. One patient had a common bile duct stone successfully extracted. Enzyme abnormalities were due to hepatitis B or medication use in 10 of 11 patients. No patient had liver biopsy. All but one of the 268 patients were discharged without further evaluation. Over one year of follow up, no patient returned for a liver-related problem. Based on these findings, only those patients with LFT levels that are twice normal and which do not normalize within 2 days warrant further evaluation. Transient LFT abnormalities may be due to decreased liver perfusion.

One hundred and twenty scabietic patients attending the outpatient clinic of the Department of Dermatology, Mansoura University Hospital, voluntarily participated in this uncontrolled, open label study to evaluate ivermectin 20 microg/kg as a scabietic after they had given their consent. The scabietic subjects included in this study were otherwise healthy, mentally competent, aged more than 18 years, and used no topical antiscabietic treatment in the week before ivermectin treatment, or during the 4-week study period. Patients were also required to show clinical evidence of scabies, and the microscopically demonstrated presence of Sarcoptes scabiei, their eggs, or their fecal pellets (scybala). A thorough history was taken, and a physical examination was conducted that included measurement of the pulse, blood pressure, temperature, and weight. For each participant, the distribution of scabies lesions was plotted on a body diagram, and the severity of disease was recorded as mild (10 or fewer lesions), moderate (11-49 lesions), or severe (50 or more lesions). Skin scrapings were examined for mites, eggs, or scybala. Urinalysis, stool analysis, a complete blood count, prothrombin time, and serum chemistry studies (serum creatinine, alanine aminotransferase (ALT), and total bilirubin) were performed before treatment, and 2 and 4 weeks after the drug was given. Ivermectin was administered as scored 6-mg tablets with water, and the dose was designed to provide 200 micrograms/kg (ivermectin was provided by Delta Pharma, Tenth of Ramadan City, Egypt). The patients were instructed to have recently worn clothing, sheets, and towels washed in a hot cycle the day after treatment. The patients were interviewed 3 days after treatment about any symptoms or subjective evidence of adverse reactions. Follow-up examinations were carried out 2 and 4 weeks after intake of ivermectin, and all examination procedures and laboratory investigations were repeated. Cure criteria included absence of nocturnal itching as well as dermatologic evidence of scabies, and negative skin scraping. Patients showing evidence of active scabies or having new lesions during the follow-up visits were given a second dose of ivermectin. All members of the household and immediate family were treated with either topical 5% permethrin cream or 1% gamma benzene hexachloride to reduce the chance of reinfestation.

The beneficial effect of ursodeoxycholic add have been documented in adults but experience with this agent is limited in the pediatric population. The objective of this study was to evaluate ursodeoxycholic acid treatment in children with cholestatic liver disease. Twenty-four patients with intrahepatic cholestasis (neonatal hepatitis 7, Byler disease 7, idiopathic intrahepatic cholestasis 10) whose ages ranged from 1.5 months to 15 years were treated with ursodeoxycholic acid (15-20 mg/kg/day) for 12 months. Liver biopsy was performed initially on all patients and on 17 at the end of the twelve months. The outcome was evaluated by monitoring clinical and biochemical markers of cholestasis, including alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase, cholesterol, total serum tasting bile acids and total and conjugated bilirubin at entry and every three months of treatment. Pruritus was ameliorated in all patients; there was complete disappearance of itching in 16.7 percent. There were significant decreases in mean serum levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin and gamma-glutamyl transpeptidase. Liver biopsy specimens showed a significant improvement in the cholestasis but not in fibrosis. No adverse effects of therapy were noted. The improvements in the clinical and biochemical parameters and tolerability of the drug suggest that ursodeoxycholic acid is a safe and effective treatment in children with intrahepatic cholestasis.

We report a 72 years old diabetic male that, after the use of combined amoxicillin-clavulanic acid, developed pruritus and jaundice. Liver function tests showed serum total bilirubin of 4.3 mg/dL aspartate aminotransferase 140 U/l (normal < 35 U/L), alanine aminotransferase 470 U/L (normal < 40) and alkaline phosphatases of 400 U/L (normal < 100). Serology for hepatitis A, B and C viruses was negative, ERCP showed a normal biliary tree and liver biopsy disclosed a cholestatic hepatitis. Ursodeoxycholic was started to relieve pruritus. Liver function tests improved shortly thereafter, suggesting that this drug may be useful in the treatment of drug induced cholestasis.
