Idiopathic neonatal hepatitis is one of the more important causes of neonatal cholestasis. It is regarded one of the clinical presentations of 'idiopathic obstructive cholangiopathy', just like extrahepatic biliary atresia. Is it not possible to discriminate between intrahepatic and extrahepatic causes of neonatal cholestasis, or between idiopathic neonatal hepatitis and metabolic, infectious, or toxic causes, by using clinical or laboratory parameters. Liver histology is slightly more helpful: giant cell formation, focal liver necrosis, and lymphocytic and neutrophilic infiltration may be found in idiopathic neonatal hepatitis. In infectious hepatitis liver pathology mostly is only a lesser part of the symptomatology. Sporadic idiopathic neonatal hepatitis has a better prognosis than familial; about 75% of children with sporadic hepatitis experience complete recovery as compared to less than 25% of children with familial hepatitis. Therapy is confined to the prevention and treatment of complications such as itching, portal hypertension and variceal bleeding, and (fat) malabsorption.

The histological appearances of liver biopsies of 13 patients who developed cholestasis following courses of flucloxacillin are presented. In most of the cases jaundice and pruritus were protracted and in nearly all cases liver function tests are yet to return to normal after mean follow-up of 18 mths. One patient died after 7 mths of jaundice and another shows clinical evidence of secondary biliary cirrhosis. Biopsies typically showed hepatocellular and canalicular bile stasis with minimal or no hepatitis. Mild portal fibrosis and a patchy portal lymphocytic infiltrate were usually present. In 4 cases bile ducts were reduced in number and in 6 cases reduced in size. Bile duct epithelium showed degenerative changes but only occasional infiltration by inflammatory cells. Ductular proliferation was quite variable and in some cases--most noticeably the fatal case--was inconspicuous despite depletion of bile ducts. The appearances suggested damage not only of hepatocytes but also of bile ducts and proliferating ductules. This may explain the prolonged and occasionally irreversible hepatic disease associated with the use of flucloxacillin. Flucloxacillin should be included amongst the causes of vanishing bile duct syndrome.

Dyslipidaemia may be treated with a number of safe and effective pharmacological agents that target specific lipid disorders through a variety of mechanisms. The bile-acid sequestrants--cholestyramine and colestipol--primarily decrease LDL cholesterol by binding bile acids, thereby decreasing intrahepatic cholesterol, and by increasing the activity of LDL receptors. Nicotinic acid lowers LDL cholesterol and triglyceride by decreasing VLDL synthesis and by decreasing free fatty acid mobilization from peripheral adipocytes. The HMG-CoA reductase inhibitors--fluvastatin, lovastatin, pravastatin and simvastatin--lower LDL cholesterol by partially inhibiting HMG-CoA reductase (the rate-limiting enzyme of cholesterol biosynthesis) and by increasing the activity of LDL receptors. The fibric-acid derivatives--bezafibrate, ciprofibrate, clofibrate, fenofibrate and gemfibrozil--primarily decrease triglyceride by increasing lipoprotein lipase activity and by decreasing the release of free fatty acids from peripheral adipose tissue. Probucol decreases LDL cholesterol by increasing non-receptor-mediated LDL clearance; as an anti-oxidant, probucol also decreases LDL oxidation; oxidized LDL which is thought to lead to atherogenesis. Although these agents have been proven safe in clinical trials, like any drug, they carry the risk for adverse effects. The bile-acid sequestrants may cause constipation, reflux oesophagitis, and dyspepsia, and may bind coadministered medications such as digitalis glycosides, beta blockers, warfarin, and exogenous thyroid hormone. Nicotinic acid use is commonly associated with flushing and pruritus and may also cause non-specific gastrointestinal complaints, hepatotoxicity (hepatic necrosis, hepatitis, or elevated liver enzymes), gout, myolysis, decreased glucose tolerance and increased fasting glucose levels, and ophthalmological complications including decreased visual acuity, toxic amblyopia, and cystic maculopathy. The HMG-CoA reductase inhibitors may produce liver enzyme elevations, creatine kinase elevations and rhabdomyolysis. The combination of a reductase inhibitor and a fibrate increases the risk for rhabdomyolysis. Possible adverse effects of the fibric-acid derivatives include abdominal discomfort, nausea, flatulence, increased lithogenicity of bile, liver enzyme elevations and creatine kinase elevations. Probucol may increase the QTc interval and may cause non-specific gastrointestinal complaints.

A prospective study was conducted to determine the etiologies of isolated pruritus among out-patients attending a hospital dermatology clinic in Lome. Two hundred and twenty patients (120 men and 100 women) suffering from isolated pruritus were included in the study. The most frequent etiologies were; digestive parasitosis (n = 50), onchocercosis (n = 45), drug allergy (n = 26), food allergy (n = 10), psychological pruritus (n = 25) and hepatitis (n = 13). The etiology was not determined for 29 cases. This study shows the large contribution of parasites to the pathogenesis of pruritus in tropical Africa.

Micronized natural progesterone is often prescribed alone or in association with beta-agonists in the treatment of preterm labor in France. We observed drug-induced hepatitis in 4 such patients. The main manifestation of liver disease was pruritus. After drug withdrawal, elevated transaminase levels continued to rise for one week then normalized within 10 to 30 days. The imputability of this undesirable effect was assessed and considered to be likely. The effectiveness of micronized natural progesterone in the prevention of premature delivery and in decreasing perinatal mortality and morbidity has not yet been proven. This drug should therefore be used with care, keeping in mind the risk of hepatitis, particularly in patients presenting with pruritus.

The clinico-pathological entity of flucloxacillin-associated cholestatic hepatitis is described and the recognition and documentation of cholestasis associated with flucloxacillin and with related isoxazolyl-penicillins (cloxacillin, dicloxacillin) is examined on an international basis, with particular reference to Australia. Data were obtained from the literature, from the Australian adverse drug reaction monitoring agency and from the Collaborative Centre for International Drug Monitoring (World Health Organisation) in Sweden. Approximately 600 cases of flucloxacillin-associated cholestatic hepatitis were collected, as well as 164 cases associated with other isoxazolyl penicillins. Jaundice and pruritus may first appear several weeks after administration of the drug has ceased and typically are severe and protracted. Liver tests may be abnormal for months after symptomatic recovery. Death is uncommon. Liver pathology shows centrizonal bile stasis with portal tract inflammation and variable loss of bile ducts. Approximately 1 in 15,000 users of flucloxacillin will develop the reaction. Increasing age (> 55 years) and prolonged intake (> 14 days) are particular risk factors. Cholestasis associated with cloxacillin/dicloxacillin appears to be similar in nature but is less well defined. Recognition and reporting of the reaction have been uncommon in the United Kingdom inter alia and high in Sweden and Australia, although estimates of risk have been similar. In Australia, the remarkably high rate of reports appears to be the result of sustained publicity for the reaction. There is only a trickle of reports of cholestatic hepatitis in association with the use of cloxacillin and dicloxacillin from the USA and Canada. The high level of awareness of the reaction and consequential regulatory action so far have not resulted in a diminution of its occurrence in Australia.

In contrast to the well known chlorpromazine-induced cholestatic hepatitis, we report the case of a schizophrenic patient who presents a cytolytic hepatitis, without any prior hepatic disease. Mr G. was first hospitalized for depressive symptomatology. A pseudo-nevrotic schizophrenia was diagnosed. Pretherapeutic clinical and biological data were normal. A treatment with chlorpromazine 400 mg/day was given. At day 8, the patient was still anxious and began to be agitated. An increase to 500 mg/day of chlorpromazine posology and an addition of haloperidol 200 mg/day was implemented. At day 10, the following clinical symptoms appeared: 38.6 degrees C fever; headache; myalgia; epigastralgia and hypocondrium pain. Biological hepatitis disturbances (ALAT, 984 U/L; ASAT, 414 U/L) and hypereosinophilia with normal white cell count were found. Clinical and biological investigations were normal. Blood-culture, A, B, C hepatitis, HIV and CMV serologies were negative. Neuroleptic treatment was discontinued. Evolution to normality of the disturbances and biological data suggested a cytolytic hepatitis. Mr G... remained treated with flupentixol without side-effects. Phenothiazine-induced cholestatis is frequent, mild, and recovers spontaneously. The biological mechanism is supposed to be immunologic. Prevalence of biological hepatic disturbances is 10 to 20% with chlorpromazine in long-term treatment. More often, symptomatology is the same; jaundice, pruritus, abdominal pain, fever. Although pharmacological data suggest for a cytotoxic activity of phenothiazines, cytolytic hepatitis is poorly described. Maximum range of transaminase blood level reported in previous studies is about 400 U/l. This level is not clearly correlated with hepatic cell lysis. Few cases of hepatic necrosis have been reported. In all cases, preexistent hepatic injuries were observed. Chlorpromazine-induced cytolytic hepatitis is uncommon and cholestatic hepatitis mild. Biological hepatic parameters investigations remain necessary during neuroleptic treatment.

Coumarin is a drug which is extensively used to treat lymphedema. We report two cases of acute hepatitis probably due to coumarin. Two women, 40 year and 45 year-old, were treated with 90 mg/d of coumarin for 5 months. Clinical features included jaundice, pruritus, and diarrhea. A marked increase in serum aminotransferases was observed (ALT: 30 and 100 times the upper limit of normal, respectively). Coumarin withdrawal was rapidly followed by a favorable outcome in both cases. Rechallenge in one case induced a relapse of symptoms and liver test abnormalities. Coumarin can induce acute cytolytic hepatitis.

A patient presented with pruritus and recent elevation of aminotransferases. The case fulfilled most of the criteria for the diagnosis of autoimmune hepatitis and achieved clinical and complete biochemical response to steroid therapy. However, the liver biopsy specimen revealed an unusual histological pattern consisting of severe centrilobular necrosis demarcated by a thin rim of hepatitic reaction. In contrast, the portal tracts appeared almost normal. This histological appearance has not been associated with autoimmune hepatitis. This presentation and the histology may represent an early pattern of autoimmune injury to the liver.

Determining the possible association of viral hepatitis infection and degree of pruritus is the primary concern of this study. Ninety-six adequately dialyzed CAPD patients (47 male and 49 female) and 526 normal controls (266 male and 260 female) were enrolled. Blood hemoglobin, ferritin, electrolytes, calcium, phosphate, albumin, urea, creatinine, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and bilirubin were analyzed by routine methods. Serum HBsAg was examined, using a radioimmunoassay method and the anti-HCV, an enzyme immunoassay method. All cases were interviewed with a standardized questionnaire. The highest possible pruritus score (PS) was 22. The prevalences of HBsAg(+) and anti-HCV(+) were 14.6% and 17.7%, respectively. The mean PS in all 96 CAPD patients was 11.6 (range 7-22). The mean PS were 11.8 +/- 0.6 and 12.5 +/- 1.0 for patients infected with HBV and HCV, respectively. Both were significantly higher than that (10 +/- 0.9) of patients without hepatitis infection. AST and ALT were significantly higher in patients infected with viral hepatitis than those without. The other biochemical parameters were not significant. Thirty-seven (38.5%) of our 96 patients had mild pruritus (PS < or = 7) and 11 (15.9%) had severe pruritus (PS > or = 15). Of the 83.9% (26/31) patients with viral hepatitis, the grades of skin itching were moderate to severe; whereas those of the patients without viral hepatitis, 53.6% (37/69) belonged to the group of moderate to severe pruritus (p = 0.003, chi 2 test with Yates' correction). The authors recommended screening of viral hepatitis infection to be undertaken for uremic patients with unexplained skin itching.
