RESUMO

We investigated symptoms suggestive of swallowing problems in patients with primary biliary cirrhosis, some of whom displayed features of sicca complex. A prospective study of 95 consecutive patients with primary biliary cirrhosis was conducted at a single teaching hospital using a questionnaire administered over the telephone. Some symptoms of sicca complex (dry mouth and/or dry eyes) were found in 65 patients (68.4%). Subjective xerostomia alone was present in 45 patients (47.4%). The questionnaire revealed an increase in incidence of dysphagia in xerostomia subjects, affecting 21 of 45 patients, compared with 6 of 50 non-xerostomia patients. Multivariate logistic regression analysis showed that confounding factors such as age, obesity, cigarette smoking, and medications associated with a dry mouth could not explain these findings. Twenty-eight patients complained of hoarseness, 23 of coughing, and 14 of wheezing, all of which were significantly more frequent than in the 50 patients without xerostomia. Heartburn affected 17 xerostomia patients and 15 non-xerostomia patients, indicating no difference in frequency between these two groups, even after age, obesity, cigarette smoking, and medications associated with heartburn were considered in the multivariate analysis. Acid regurgitation, nausea, and vomiting were also similar in frequency between patients with and without xerostomia. Swallowing problems, manifested primarily as dysphagia, are common in primary biliary cirrhosis patients who have subjective xerostomia.

RESUMO

OBJECTIVE: To describe the hepatotoxicity associated with ingestion of the Chinese herbal product Jin Bu Huan Anodyne Tablets (Lycopodium, serratum) and to propose possible mechanisms of injury. DESIGN: Retrospective analysis. SETTING: Academic hepatology units and private practice facilities. PATIENTS: Seven previously healthy patients. MEASUREMENTS: Clinical, laboratory, radiologic, and histologic studies. RESULTS: Acute hepatitis occurred after a mean of 20 weeks (range, 7 to 52 weeks) of Jin Bu Huan ingestion and resolved in six patients within a mean of 8 weeks (range, 2 to 30 weeks); another patient is currently improving. Hepatitis was associated with symptoms of fever, fatigue, nausea, pruritus, and abdominal pain and with signs of jaundice and hepatomegaly. Biopsy specimens showed that one patient had hepatitis with eosinophils (consistent with a drug reaction) and the other had mild hepatitis, moderate fibrosis, and microvesicular steatosis. Decreasing the Jin Bu Huan dose in one patient improved liver test results. Reusing Jin Bu Huan in two other patients caused abrupt recrudescence of hepatitis. CONCLUSION: Jin Bu Huan can cause liver injury. Although the hepatotoxic mechanisms are not defined, they may include hypersensitive or idiosyncratic reactions or direct toxicity to active metabolites. Hepatotoxicity caused by herbal products underscores the toxicity caused by herbal products underscores the importance of national surveillance programs and quality control of the manufacture of these products.

RESUMO

Ursodeoxycholic acid, a dihydroxyl bile acid normally present in human beings in minimal amounts, becomes incorporated into the bile salt pool when taken orally. In cholestasis, bile acids are retained in the liver and are hepatotoxic. Ursodeoxycholic acid is the least-known hepatotoxic bile acid, has choleretic properties and is reported to benefit patients with chronic cholestasis. In a nationwide Canadian controlled trial, 222 patients with primary biliary cirrhosis were treated with ursodeoxycholic acid (14 mg/kg/body wt/day) or placebo for 24 mo. Only patients with a diagnosis confirmed by liver biopsy and serum positive for antimitochondrial antibodies were enrolled; 88% were symptomatic on entry. The primary outcome measure was percent change in total serum bilirubin from baseline to final follow-up. Treated patients (111) and controls (111) were comparable with regard to age, gender, biochemical parameters and liver histological condition. Although treatment was not associated with any improvement in symptoms, ursodeoxycholic acid therapy caused the bilirubin to fall significantly within the first 3 mo of therapy (p < 0.001). Significant falls in serum alkaline phosphatase, aminotransferases, cholesterol and IgM levels were also noted in the treated group. Improvement in some histological features was observed but there was no difference between the groups in the number of patients who reached the endpoints of death or liver transplantation. Ursodeoxycholic acid, given to patients with primary biliary cirrhosis, leads to an improvement in serum markers of cholestasis. A larger sample size is needed to determine whether ursodeoxycholic acid therapy has a beneficial effect on the survival of patients with primary biliary cirrhosis.

RESUMO

This study reports on a group of 20 patients with an initial diagnosis of primary biliary cirrhosis (PBC) whose serum tested negative for antimitochondrial antibodies by immunofluorescence. All had a clinical history compatible with primary biliary cirrhosis, and results of biochemical, histological, and radiological investigations were consistent with this diagnosis despite the absence of antimitochondrial antibodies by immunofluorescence. For comparison, these patients were matched for sex and serum bilirubin with 20 antimitochondrial antibody positive (> 1:160) and histologically confirmed primary biliary cirrhosis patients who served as controls. Serum samples from both groups were retested blindly for antimitochondrial antibodies using immunoblotting and for antibodies to the major M2 mitochondrial autoantigens by enzyme linked immunosorbent assay (ELISA). Three antimitochondrial antibody immunofluorescence negative patients had antimitochondrial antibodies by immunoblotting and ELISA; the remaining 17 patients were confirmed negative by all methods. The antimitochondrial antibody immunofluorescence positive controls were verified by immunoblotting or ELISA, or both. All 17 patients negative for antimitochondrial antibodies had antinuclear antibodies, often in high titres, compared with 3/17 of the antimitochondrial antibody positive controls (p = 0.0001). Additionally, the antimitochondrial antibody negative group also had significantly higher smooth muscle antibody titres (p = 0.03) and lower serum IgM (p = 0.01) and aspartate aminotransferase (p = 0.03) activities than the antimitochondrial antibody positive controls. Analysis of clinical findings, histological tests, serum bilirubin, alkaline phosphatase, alanine aminotransferase, and IgG, disclosed no significant differences between the two groups. This paper describes a group of patients with the clinical and histological features of PBC but who do not fulfil the usual criteria necessary to make this diagnosis. Because they also have very high titres of antinuclear antibodies, smooth muscle antibodies, and comparatively low IgM and aspartate aminotransferase activities, we believe they are distinct from PBC and have a syndrome of autoimmune cholangitis.
