Pegylated interferon and ribavirin in re-treatment of responder-relapser HCV patients.

BACKGROUND: The re-treatment of patients who relapse after a course of standard interferon and ribavirin with pegylated interferon alfa-2b plus ribavirin is an open issue. AIMS: To evaluate efficacy and safety of treatment with pegylated interferon alfa-2b plus ribavirin and the role of early HCV-RNA assessment as a predictor of sustained response. PATIENTS: Between May 2001 and December 2002, 242 consecutive patients with chronic hepatitis C were enrolled in an open, regional, multicentre study. Seventy-eight of them were responder-relapsers to a previous course of combination therapy. METHODS: Patients were treated with pegylated interferon alfa-2b (1 microg/kg/week) plus ribavirin (800-1200 mg daily). Qualitative HCV-RNA was performed at week 2. Genotypes 1-4 were treated for 48 weeks, while genotypes 2 and 3 were treated for 24 weeks. RESULTS: We obtained an overall sustained virological response rate of 41.0% (78.6% for patients with genotypes 2-3). CONCLUSION: This treatment schedule prove to be safe and effective in relapsers with genotype non-1 while genotype 1-4 patients had a low rate of sustained virological response. Qualitative virological assessment after 2 weeks may identify patients who are more likely to reach sustained virological response, but it is not a valid tool for a stopping rule approach.

Seasonal patterns of hospital treatment for inflammatory bowel disease in Italy.

AIM: It is still debated whether clinical flare-ups of chronic inflammatory bowel disease follow a seasonal pattern, and the various reports are based on general practitioners' records or hospital discharge charts. There are, however, no specific figures for treatment in hospital gastroenterology units, which serve as a reference point for these disorders. This study was therefore designed to investigate whether there is a seasonal pattern in admissions for inflammatory intestinal disease in Italy, differing from what is generally known about gastrointestinal pathologies, since there are no nation-wide figures on the subject. METHODS: The RING (Ricerca Informatizzata in Gastroenterologia) project is an observational study collecting hospital discharge forms from 22 centers in Italy. RESULTS: From winter 2000 to autumn 2003, the 22 gastroenterology units participating in the RING project discharged 32,357 patients following ordinary hospital admissions. Of these, 2,856 (8.8%) had a main diagnosis of inflammatory bowel disease: 1,541 Crohn's disease, and 1,315 ulcerative colitis. No seasonal patterns were detected for either category, or when the analysis was done by age, sex and site of disease. CONCLUSIONS: The most serious flare-ups of inflammatory bowel disease, i.e. those requiring routine hospital treatment, do not appear to follow any seasonal pattern, regardless of the site of the disease or the patient's age or sex.

[Intraoperative use of radiofrequency thermoablation of liver tumors: considerations on indications and related therapeutic aspects]. / L'impiego intraoperatorio della termoablazione a radiofrequenza di neoplasie epatiche: considerazioni su indicazioni ed aspetti terapeutici associati.

PURPOSE: To evaluate the usefulness of intraoperative radiofrequency thermoablation of liver tumours in association or not with hepatic resection. MATERIALS AND METHODS: 21 patients were treated between January 1998 and December 2001, there were 4 hepatocellular carcinoma and 17 metastasis. In 13 cases radiofrequency was associated to hepatectomy, in 3 cases to resection of extraepatic disease and in 5 cases were performed alone. 23 lesions were treated by radiofrequency (range 1-3); the mean dimension was 26 millimetres (range 8-70). A clamping of the liver pedicle was always done. RESULTS: There were no operative deaths, 3 (14.3%) patients developed complications related to radiofrequency (2 biliary leakages, 1 hepatic abscess). 14 (66.7%) patients were alive after a mean follow up of 14.5 months, 2 of all (9.5%) had a recurrence in the site previously treated with thermoablation. Association between hepatectomy and radiofrequency increased the number of curative liver resections from 10.1% to 16.3% (in case of colorectal metastasis). DISCUSSION: Intraoperative radiofrequency is useful to increase the number of curative hepatectomies, to treat liver masses which demonstrate unresectable or found by ultrasonography at the operating time and even to reach tumours difficult to manage by percutaneous approach. In any case the aim is to obtain the absence of macroscopic neoplastic disease (RO status). It is a safe and effective therapeutic strategy, anyway all procedures and indications are still not completely cleared. CONCLUSIONS: Intraoperative thermoablation of liver tumour is safe and effective and increases therapeutic the number of curative hepatectomies. Further progresses may improve the efficacy and extend the indications of this strategy.
