ABSTRACT

Life-long hepatitis B immunoglobulin (HBIG) administration is a main component of prophylactic strategy to prevent hepatitis B virus (HBV) reinfection after liver transplantation (LT). Long-term effects of HBIG treatment are known only for intravenous (IV) and intramuscular formulations. To evaluate safety and efficacy of self-administered SC HBIG, 135 LT patients receiving a 48-week treatment were analyzed. The dose of HBIG was 500 IU or 1000 IU if body weight was <75 kg or ≥75 kg, respectively. Patients were switched from the monthly IV HBIG treatment to weekly SC HBIG 2-3 weeks after the last IV dosage. All patients were able to SC self-injection after a single training. The treatment was effective in maintaining trough anti-HBs levels >100 IU/L. No severe drug-related side effects occurred. Fifteen injection-site small hematomas and four cases of mild itch occurred. At the end of the study, anti-HBs median titer was 232 IU/L (115-566 IU/L) and 97.8% of patients had an anti-HBs level >150 IU/L. Due to high mean level of anti-HBs titers observed during this study, individualized treatment schedules should be further investigated. In conclusion, SC HBIG for long-term prophylaxis of post-LT HBV reinfection resulted safe, well accepted, and effective in maintaining adequate anti-HBs levels.

ABSTRACT

BACKGROUND AND STUDY AIMS: Ingestion of foreign bodies is a common occurrence. Few papers in the literature report experience and outcome at tertiary centers. The aim of this paper is to report the management and the outcomes in 414 patients admitted for suspected ingestion of foreign body between May 1995 and December 1999. METHODS: A plain radiographic film of the neck, chest or abdomen was obtained in the case of radiopaque objects, and in order to rule out suspected perforation: in such cases a computed tomography (CT) study was also performed. All patients were asked to give their informed consent, which was refused by three patients. Anesthesia was always used, either conscious sedation (86.8 %), or general anesthesia in the case of poor patient tolerance (13.2 %). All patients underwent an endoscopic procedure within six hours of admission. A flexible scope was used in all patients and a wide range of endoscopic devices was employed. RESULTS: Foreign bodies were found in 64.5 % of our patients. Almost all were found in the esophagus. The types of foreign body were very different, but they were chiefly food boluses, bones or cartilages, dental prostheses or fish bones. In three patients (1.1 %) it was impossible to endoscopically remove the foreign body, which was located in the cervical esophagus: all these three patients required surgery. No complications relating to the endoscopic procedure were observed, but 30.7 % of patients had an underlying esophageal disease, such as a stricture. Only eight patients required a second endoscopic procedure, performed by a more experienced endoscopist. CONCLUSION: Foreign body ingestion represents a frequent reason for emergency endoscopy. The endoscopic procedure is a successful technique which allows the removal of the foreign bodies in almost all cases without significant complications. Surgery is rarely required.

ABSTRACT

BACKGROUND: Biliary tract complications are frequent after orthotopic liver transplantation. Late biliary tract complications occurring after T-tube removal mostly include stones and strictures which may be associated with sepsis and worsening of the liver function. Endoscopic retrograde cholangiopancreatography (ERCP) has a role in the diagnosis and therapy of these complications. The aim of our study was to report our experience of endoscopic diagnosis and treatment of late biliary tract complications in liver-transplanted patients. METHODS AND RESULTS: One hundred and thirty-six adult liver-transplanted patients have been followed since 1988. Seventeen patients (12.5%) needed a total of 30 ERCP because of evidence of clinical and/or biochemical cholestasis: eight with biliary stricture; six with biliary stones; one with both stricture and stones; and two with normal ERCP findings. Interventional endoscopic procedures included 14 sphincterotomies, six stone removals, seven biliary balloon dilatations, seven biliary stent placements, 11 biliary stent replacements, seven nasobiliary catheter placements and one mechanical lithotripsy. No complications were seen. In all cases, ERCP was able to identify the location, entity and dimension of the late biliary tract complication, thus allowing a therapeutic strategy to be used. Two patients had medical cholestasis. Forty-seven per cent of patients with late biliary tract complications could definitely be cured by ERCP alone. The ERCP improved the patients' condition to allow subsequent surgery in five patients (33%). CONCLUSIONS: These results confirms that ERCP is a valuable diagnostic tool and should be considered as the first step in the non-surgical management of late biliary tract complications after orthotopic liver transplantation.

ABSTRACT

The role of clinical (biliary pain and/or jaundice), laboratory (discriminant function (DF) calculated using AST, ALT, AlkPh and GGT serum values) and ultrasonographic (US)(dilation and/or stone of common bile duct (CBD)) findings in identification of the biliary etiology of acute pancreatitis (AP) was studied in 60 patients. AP biliary etiology was defined by ERCP executed in the early phase of the disease (lithiasis and/or stenosis of CBD; endoscopic features of forced papilla in patients with gallstone). US showed the best values of sensitivity (84.6%) and diagnostic efficacy (76.7%); DF showed the best results of specificity (62.5%) and of test positive predictive value (92.8%). The statistical evaluation (McNemar test) showed a significant increase of sensitivity for US vs clinical findings and of specificity for DS vs clinical findings (p less than 0.05). The sensitivity, specificity, accuracy, test negative and positive predictive value were improved to 96.1, 87.5, 96.6, 77.1 and 92% by the combination of US and DF. Therefore the association of US and DF can provide the best non invasive method in rapidly detecting CBD pathology as an etiological factor in AP and then the enough accurate indication to early operative ERCP.

ABSTRACT

A case of acute steatosis in pregnancy featuring unusually severe cholestasis is discussed with details of the successful outcome for mother and foetus. The correspondence between clinical picture, histological and ultrasound findings is reported together with a detailed review of the latest reports in the literature and what they reveal about the true incidence of the disease, the variability of the clinical picture, whether and when it is better for both mother and child to interrupt.
