[Cholestatic viral hepatitis A in adults. Clinical, biological and histopathological study of 9 cases].

OBJECTIVES: We report here 9 cases of acute viral hepatitis A leading to hospitalization between June 1989 and October 1992. The main feature was a marked and protracted cholestasis. RESULTS: Jaundice lasted an average of 77 +/- 39 days (range: 30-120) and total serum bilirubin concentrations were 265 +/- 184 mumol/L (range: 51-560). IgM anti-HAV was present in the serum for 6.3 +/- 5.5 months (median: 4, range: 2-19). Histopathological examination of the liver was performed in 6 patients and most showed intralobular cholestasis and portal tract inflammation associated with dystrophy and paucity of bile ducts. Acute renal failure was noted in one patient. In three patients, whose pruritus was not relieved by cholestyramine, plasma exchange was an effective therapy. CONCLUSION: These case reports confirm the severity of viral hepatitis A in adults and emphasize the importance of vaccination.

[Cystadenoma of the liver. Clinical, radiological and anatomopathological study of 5 cases, one associated with cystadenocarcinoma].

We describe the clinical, radiological and pathological features of 5 cases of cystadenoma, one associated with cystadenocarcinoma. In 3 of these patients, the presence of thick wall, endoluminal buds and septations at imaging investigations was suggestive of the diagnosis of cystadenoma or cystadenocarcinoma. In 2 of these patients, these imaging features were lacking. In 2 of these patients, partial surgical resection was performed and was followed by recurrence of the tumor. In all cases, the diagnosis was confirmed by pathology examination of the resection specimen. In conclusion, this study shows that diagnosis of cystadenoma or cystadenocarcinoma may be very difficult because of the absence of suggestive imaging features in some cases, and confirms that complete resection of the tumor, allowing pathology confirmation, is needed for the optimal treatment of cystadenoma or cystadenocarcinoma.

Hypnotic relaxation: a new sedative tool for colonoscopy?

Sedation is often justified in patients requiring colonoscopy. We investigated the potential usefulness of hypnotic relaxation in 13 women and 11 men (median age, 43 years; range, 22-67) for whom other forms of anesthesia were not available. Hypnotic relaxation resulted in moderate or deep sedation in 12 patients (nine women; p < 0.05). In the patients in whom hypnosis was successful, pain was less intense than in patients in whom hypnosis was unsuccessful (p < 0.001). In addition, all colonoscopies were completed in the successful group, versus 50% in the unsuccessful group (p < 0.05). The patients in the successful group all agreed to another examination under the same conditions, whereas only 2% in the unsuccessful group agreed (p < 0.001). Our study suggests that, in a subgroup of hypnotizable patients, hypnotic relaxation may be a safe alternative to drug sedation and merits further study.

AIDS-related cholangiopathy. Critical analysis of a prospective series of 26 patients.

Several types of biliary tract abnormality of undetermined origin have been described among AIDS patients. The aims of this study are: (1) to evaluate whether biliary tree involvement is in fact one or several homogeneous morphological entities, (2) to specify the role of CMV or Cryptosporidium sp. infection, and (3) to evaluate the possible efficacy of treatment. Since ultrasound had revealed abnormality in the biliary tree, 26 consecutive AIDS patients underwent cholangiography. Cholangiograms enabled us to distinguish between two types of biliary tract involvement: (1) gradual and regular stenosis of the terminal portion of the common bile duct associated with dilation but without irregularity of the intrahepatic biliary ducts was present in 27% of our cases, and (2) distal stenosis of the extrahepatic biliary ducts combined with diffuse irregularity of the caliber of the intrahepatic bile ducts was present in 73% of our cases. Concomitant infection by CMV or Cryptosporidium sp. was significantly more frequent when intrahepatic duct irregularities were present (94%) than when absent (14%, P < 0.001). Anti-CMV treatment and sphincterotomy were unsuccessful in treating anomalies of the intrahepatic biliary tract. Conversely, sphincterotomy caused rapid and lasting disappearance of pain in all our patients. In conclusion, biliary tract involvement in AIDS patients is of two types. CMV infection and infection by Cryptosporidium sp. are most frequent when the large intrahepatic ducts are implicated.

Grand mal seizures as a complication of treatment with pefloxacin in patients with cirrhosis. A report of three cases.

In this paper, three cases of grand mal seizures are reported as a complication of pefloxacin at usual doses (400 mg twice a day) in patients with cirrhosis. Grand mal seizures occurred from 12 h to 8 days after the onset of pefloxacin treatment. In 1 case, seizures recurred after inadvertent rechallenge with the drug. Elevated pefloxacin serum levels were demonstrated in 2 cases. Brain computed tomography in all 3 cases and cerebrospinal fluid examination showed normal results. No etiology other than pefloxacin overdose was found. After pefloxacin withdrawal, no recurrence of seizures were observed. Therefore, when pefloxacin treatment is indicated for cirrhotic patients, a reduced dosage and/or careful monitoring of pefloxacin serum levels should be recommended.

Liver disease from surreptitious administration of urethane.

We report subacute necrosis, peliosis hepatis, venoocclusive disease and hepatic angiosarcoma after long-term administration of urethane. We take this to be the 12th case of urethane-induced hepatitis and the first associated with vascular liver tumor.

Systemic lupus erythematosus and chronic intestinal pseudoobstruction.

We describe the first case of a patient with systemic lupus erythematosus in which clinical and radiological features, small bowel manometry and histological studies were consistent with the diagnosis of chronic intestinal pseudoobstruction. Our patient developed a fatal form of lupus with cerebral angiitis and tubulointerstitial lupus nephritis, with no sign of progressive systemic sclerosis or dermatopolymyositis. Postmortem examination confirmed the presence of an extensive fibrotic process in the muscularis layers, whereas the muscularis mucosae and the innervation of the digestive wall were spared.

Chronic administration of cyclosporin A induces a decrease in hepatic excretory function in man.

Chronic administration of cyclosporin A may induce cholestasis in a few patients. The purpose of this study was to examine the effect of chronic administration of cyclosporin A on serum bile acid levels, serum bilirubin concentration, and bromosulfophthalein plasmatic fractional clearance. Twenty heart-transplanted patients with normal serum alanine aminotransferase activity receiving cyclosporine A during a mean duration of 33 months (range 7-54) were compared to 20 matched kidney-transplanted patients with normal serum alanine aminotransferase receiving azathioprine for a mean duration of 34 months (range 6-72). As compared to azathioprine-treated patients, patients treated with cyclosporin A had an increase in serum bile acid levels of 32% (P < 0.01), an increase in serum bilirubin concentration of 100% (P < 0.001), and a decrease in bromosulfophthalein plasmatic fractional clearance of 60% (P < 0.001). These results suggest that cyclosporin A induces a decrease in hepatic excretory function in man.

Severe hypoxemia-associated intrapulmonary shunt in a patient with chronic liver disease: improvement after medical treatment.

A 20-yr-old woman with chronic liver disease and angioimmunoblastic lymphadenopathy presented with marked hypoxemia caused by intrapulmonary shunt. Her respiratory tract showed her to be free of angioimmunoblastic lymphadenopathy manifestations. After 12 months of treatment with cyclophosphamide and corticosteroid, the immunologic disease disappeared. Unexpectedly, hypoxia-associated intrapulmonary shunt was no longer present either. To the best of our knowledge, this is the first case of dramatic improvement, with medical therapy, of severe hypoxemia related to noncirrhotic liver disease. However, the mechanism by which this treatment caused the regression of intrapulmonary shunt is unknown.
