In an 8-h period, five members of two kindred families suddenly became ill with nausea, vomiting, and malaise. This was followed by acute liver disease, a generalized bleeding tendency, and a low platelet count. Two of the patients died four and five days after onset of illness. It was established that dimethylnitrosamine had been intentionally added to lemonade and milk that were consumed by the victims.

Despite standardization, marked interindividual variation in the severity of the disulfiram-alcohol reaction (DAR) has been observed. We studied the DAR in 51 consecutive alcoholics with (n = 16) and without (n = 35) significant alcoholic liver disease. Clinical signs of the DAR were much weaker in the patients with compared with those patients without liver disease. Because acetaldehyde is thought to be the main cause of the DAR, we studied ethanol and acetaldehyde kinetics in 13 patients (6 females, 7 males) with alcoholic liver disease (documented by biopsy, clinical and/or radiological findings, and by quantitative liver function) [galactose elimination capacity (GEC) 4.2 +/- SD 1.0 mg/min/kg; aminopyrine breath test (ABT) 0.14 +/- 0.10% dose x kg/mmol CO2] and 13 age- and sex-matched controls (alcoholics without significant liver disease, GEC 7.1 +/- 0.7; ABT 0.81 +/- 0.35). Clinical signs of acetaldehyde toxicity during the DAR (flush, nausea, tachycardia, and blood pressure drop) were absent in alcoholic liver disease, but clearly evident in controls. Blood ethanol kinetics were similar in both groups, Cmax and area under the concentration-time curve (AUC) being 6.27 +/- 1.82 and 368.9 +/- 72.9 mmol x min/liter in alcoholic liver disease, and 6.62 +/- 1.71 and 377.6 +/- 124.5 in controls, respectively. In contrast, there was a strong (p < 0.001) difference in Cmax and AUC of acetaldehyde, respective values being 33.46 +/- 21.52 and 1463.8 +/- 762.5 mumol x min/liter in alcoholic liver disease, and 110.87 +/- 56.00 and 4162.0 +/- 2424.6 in controls.(ABSTRACT TRUNCATED AT 250 WORDS)

The US Food and Drug Administration approved the contraceptive implant system, Norplant, in February 1990. It has been used in other countries for more than 15 years before the US approved it. The 6 subdermally placed capsules in the upper inner arm release 50-80 mcg levonorgestrel/day into the bloodstream, resulting in a 99.8% efficacy rate. Patient education and counseling, especially about changes in the bleeding pattern and Norplant's inability to protect against sexually transmitted diseases, are important to maintain client satisfaction and continued use of Norplant. Side effects, from most to least common, are changes in menstrual bleeding, constant bleeding, missed periods, weight gain/increased appetite, headache, oily skin or acne, weight loss/nausea, breast tenderness, nervousness or loss of appetite, and hair loss. It is rare when complications are so severe that they require removal of the implants. Contraindications to Norplant include active liver disease, active thromboembolic disease, breast cancer, pregnancy, and undiagnosed dysfunctional uterine bleeding. Antiepileptic medications, barbiturates, treatment for tuberculosis, and Butazolidin/phenylbutazone reduce Norplant's efficacy. A trained person should insert Norplant within the first 5-7 days of the menstrual cycle when it is evident there is no pregnancy. Some reports recommend that, after childbirth, it should be inserted 6 weeks postpartum to avoid hemorrhage. Yet, nurse-midwives at the Center for Addiction and Pregnancy at the Francis Scott Key Medical Center in Baltimore, Maryland, insert Norplant 24-48 hours postpartum in non-breast-feeding mothers with no increase in hemorrhage. Norplant must be removed no longer than 5 years after insertion. Certified nurse-midwives wanting to incorporate Norplant into their practices should follow the Guidelines for the Incorporation of New Procedures into Nurse-Midwifery Practice and have available a consulting physician who is familiar with and skilled in inserting Norplant. The manufacturer conducts training sessions for health professionals.

Nutritional problems are very common in patients with liver disease. The underlying liver disease will cause anorexia, nausea, and a poor appetite. In addition, alcohol acts as "cheap calories" and may be an added problem. Physicians taking care of patients with liver disease often place them on restrictive diets that compound the nutritional problem. Patients must be addressed for both the liver disease and the nutritional problems its treatment may create. One very important fact is that the majority of patients with liver disease will tolerate standard formulas that are much more "cost-effective" for the patients. How to calculate caloric and protein needs and how to select certain formulas are addressed. The results that show nutritional support is beneficial in decreasing mortality and morbidity are reviewed.

Alcohol withdrawal syndrome (AWS) may result in nausea, vomiting, diarrhea, weakness, sweating, tremors, tachycardia, hypertension, agitation, delirium, hallucinations, seizures, and death beginning 6 hours after alcohol cessation in alcoholics. Benzodiazepines are cross-tolerant with ethanol and are considered first-line therapy for treating AWS. Chlordiazepoxide and diazepam are first metabolized by hepatic oxidation, then glucuronidation. Lorazepam and oxazepam undergo only hepatic glucuronidation. Benzodiazepine oxidation is decreased in persons with liver disease and the elderly. Accumulation with resultant excessive sedation and respiratory depression may be significant when administering chlordiazepoxide or diazepam to patients with impaired oxidative metabolism. Lorazepam and oxazepam metabolism is minimally affected by age and liver disease. Chlordiazepoxide and diazepam are erratically absorbed by the intramuscular route. Lorazepam is predictably absorbed by the intramuscular route. Oxazepam is not available in parenteral form. Lorazepam appears to be the safest empiric choice among the various benzodiazepines for treating AWS in the elderly and in patients with liver disease, or those who require therapy by the intramuscular route.

Of all foodborne infectious diseases, infection with Vibrio vulnificus is one of the most severe; the case-fatality rate for V. vulnificus septicemia exceeds 50%. In immunocompromised hosts V. vulnificus infection can cause fever, nausea, myalgia, and abdominal cramps 24-48 hours after eating contaminated food; because the organism can cross the intestinal mucosa rapidly, sepsis and cutaneous bullae can occur within 36 hours of the initial onset of symptoms. Cases are most commonly reported during warm-weather months (April-November) and often are associated with eating raw oysters. During April 1993-May 1996, a total of 16 cases of V. vulnificus infection were reported in Los Angeles county. Fifteen (94%) of these patients were primarily Spanish-speaking, 12 (75%) had preexisting liver disease (associated with alcohol use or viral hepatitis), all were septicemic, and all had eaten raw oysters 1-2 days before onset of symptoms. In May 1996, three deaths related to V. vulnificus infection among primarily Spanish-speaking persons were reported to the Los Angeles County Department of Health Services (LACDHS). This report summarizes the findings of the investigations of these fatal cases and illustrates the importance of prevention strategies for persons with preexisting liver disease.

Flutamide is a nonsteroidal antiandrogen agent. Since it was marketed in February of 1989 in the USA for treatment of prostate cancer, its potential for hepatotoxicity has been reported in Western countries. Here we report the case of a 72-year-old patient who suffered from general malaise, poor appetite, nausea and jaundice after six months of flutamide therapy for the treatment of prostate cancer. He had no past history of liver disease and was not receiving other medications. Liver biochemistries revealed elevated serum alanine aminotransferase and aspartate aminotransferase concentrations of up to 1,035 U/l and 745 U/l, respectively. Serum total bilirubin concentration was elevated to 7.0 mg/dl. Serologic markers for acute viral hepatitis were all negative. Serum antinuclear antibody, antimitochondrial antibody and antismooth-muscle antibody were also negative. Percutaneous liver biopsy revealed pericentral zonal necrosis with bridging hepatic necrosis. The patient's clinical symptoms and signs began to improve after discontinuation of flutamide, and his liver function had returned to normal three months later. Roussel Uclaf causality assessment for adverse drug reaction confirmed the diagnosis of drug-induced liver injury. This case reminds us that patients who are receiving flutamide should be regularly monitored for liver function. If drug-induced liver injury is suspected, flutamide must be discontinued promptly to avoid progression of liver injury.

The liver has a central role in the metabolism of many drugs, since this organ is the main site of biotransformation of endo- and xenobiotics. Water-soluble drugs have a small volume of distribution and can be eliminated unchanged in the urine. By contrast, lipid-soluble drugs have a larger volume of distribution and require conversion to water-soluble metabolites for their elimination in urine or bile. The liver with its specific receptors, transporters and enzymes is responsible for the uptake, transformation and excretion of the lipophilic drugs. While most of the drugs are transformed into stable metabolites, other drugs form reactive, potentially toxic, metabolites producing liver cell damage. Liver injury caused by drugs may mimic almost any kind of liver disease. Clinical findings are gastrointestinal symptoms with nausea, vomiting and abdominal pain, cholestatic liver injury with jaundice and pruritus of severe inflammatory and cirrhotic liver damage with signs of liver failure, encephalopathy and cerebral edema. The morphological changes vary from hepatitis, cholestasis, fatty liver, granulomatous hepatitis, peri-/portal inflammation, to fibrosis with cirrhotic alterations and vascular lesions and tumors. The most commonly used drugs causing severe liver injury are discussed in detail. These are anabolics, oral contraceptives, antituberculous and antifungal agents, nonsteroidal anti-inflammatory drugs, ring substituted amphetamins ("designer drugs"), antiarrhythmics and antibiotics.

Twenty-four patients with chronic hepatitis B virus (HBV), antibody to hepatitis B e antigen (anti-HBe), HBV DNA positivity, and alanine transaminase (ALT) elevation who failed previous interferon alfa (IFN-alpha) therapy were included in a pilot study of combination therapy with ribavirin and IFN-alpha. The patients received daily oral ribavirin (1,000-1,200 mg according to body weight) plus 5 million units (MU) IFN-alpha2b three times a week for 12 months and were followed-up for 12 months. The median viremia level decreased significantly at the end of treatment (1.2 x 10(3) copies/mL) and follow-up (4.0 x 10(2) copies/mL) compared with the baseline (3.0 x 10(6) copies/mL; P <.05). After 12 months, 8 of 24 (33%) patients had cleared HBV DNA and 12 (50%) had normal ALT levels. At the end of the study virological and biochemical response was 50% and 21%, respectively. Thus, virological and biochemical response sustained in 5 of 24 (21%) patients retreated with ribavirin and IFN-alpha; none of them lost hepatitis B surface antigen (HBsAg). Liver histology improved in 2 of 4 sustained responders but in none of the 12 nonresponders with paired biopsies (P =.05). The response was independent of dose and duration of previous treatment, viral load, or the distribution of HBV precore wild-type/mutant variants. However, sustained responders had significantly higher necroinflammation (P =.036) and fibrosis (P =.007) scores. IFN-alpha-related side effects were mild and reversible on discontinuation. In 4 (17%) patients who suffered nausea and diarrhea the ribavirin dosage was reduced by 50% after 1 month of therapy and finally discontinued in all of them. No patient had liver disease decompensation. In summary, combination therapy with ribavirin and IFN-alpha may be efficacious to treat viremic anti-HBe-positive patients with chronic hepatitis B who have failed previous IFN therapy.

Symptoms related to fungal esophagitis were studied in patients with alcoholic liver disease who underwent upper gastrointestinal endoscopy. Data of 517 patients were studied retrospectively (group I) and 100 alcoholic liver disease patients, that were successively admitted to hospital, were enrolled in the prospective part (group II). Out of the 41 cases with fungal esophagitis found in group I, data of 38 could be evaluated. In group II 13 of the 93 evaluable patients had fungal esophagitis; according to Kodsi's grading 10 patients had grade 1., one patient grade 2. and two patients grade 2-3. oesophagitis. There was no case with grade 4. esophagitis. The rate of symptoms among the 51 patients with fungal esophagitis was: anorexia 23 (45.0%), abdominal pain 22 (43.1%), vomiting 17 (33.3%), nausea 15 (29.4%), occult gastrointestinal bleeding 12 (23.5%), weight loss 9 (17.6%), melena 7 (13.7%), bloating 6 (11.7%), acidic regurgitation 3 (5.8%), haematemesis 2 (3.9%), thoracic pain 2 (3.9%), singultus 1 (1.9%), odynophagia 0 and dysphagia 0. In 7 patients (13.7%) none of the studied symptoms could be identified. Despite the relatively high frequency of symptom free fungal esophagitis reported in the literature, the total lack of odynophagia and dysphagia in our patient group was remarkable. In the lack of deglutition disorders the other symptoms do not raise the suspicion of esophagitis. The diagnosis in such cases can be established only by endoscopy.
