Premature discontinuation of interferon plus ribavirin for adverse effects: a multicentre survey in 'real world' patients with chronic hepatitis C.

BACKGROUND: Interferon-alpha plus ribavirin therapy for chronic hepatitis C is associated with adverse effects that lead to therapy discontinuation in up to 27% of patients in randomized controlled trials. AIM: To examine the causes and predictive factors for therapy discontinuation in patients treated in current clinical practice. METHODS: We retrospectively enrolled 441 consecutive patients, scheduled to receive interferon-alpha + ribavirin for chronic hepatitis C, in five centres. Patients had been treated with 3 or 6 MU interferon-alpha three times a week plus ribavirin, 800-1200 mg daily, for 6 or 12 months. RESULTS: One hundred and eight [24.5%; confidence interval (CI), 20.5-28.8%] patients failed to finish combination therapy because of adverse events. The discontinuation rate was higher during the first 6 months of treatment; anaemia was an important cause (36.1% of discontinuations); unexplained lipothymia resulted in discontinuation in 11 patients. Female gender [hazard ratio (HR) = 1.85; CI, 1.17-2.92], an interferon-alpha dose > 15 MU/week (HR = 1.79; CI, 1.12-2.86) and no previous interferon-alpha treatment (HR = 1.63; CI, 1.04-2.57) were independent factors associated with discontinuation. The simultaneous presence of these factors identified patients at high risk for discontinuation [odds ratio (OR) = 10; CI, 3.98-25.13]. CONCLUSIONS: The study identified some predictive factors for adverse event-related discontinuation, which may improve the safety profile and effectiveness of interferon-alpha + ribavirin combination therapy in chronic hepatitis C.

Tamoxifen in the treatment of hepatocellular carcinoma: 5-year results of the CLIP-1 multicentre randomised controlled trial.

BACKGROUND: In 1998, when data of a meta-analysis on tamoxifen in the treatment of hepatocellular carcinoma (HCC) had suggested a little advantage for this treatment, we published the results of a multicenter randomised controlled trial, that showed no survival benefit for tamoxifen vs. control. Here we report an updated analysis of the study results 4.5 years after the closure of enrollment. METHODS: The study had a planned sample size of 480 patients. Patients with any stage HCC were eligible, irrespective of locoregional treatment. Tamoxifen was given orally, 40 mg/die, from randomisation until death. RESULTS: 496 patients were randomised by 30 Institutions from January 1995 to January 1997. Information was available for 477 patients. As of July 2001, 374 deaths (78%) were recorded, and median survival times were 16 and 15 months (p=0.54), in the control and tamoxifen arm. Data were further analysed separately for advanced patients and for those eligible to potentially curative locoregional treatments: relative hazard of death for patients receiving tamoxifen was equal to 0.98 (95% CI 0.76-1.25) for the former group and 1.38 (95% CI 0.95-2.01) for the latter. The prognostic score recently devised by our group (CLIP score) was, as expected, strictly correlated (p<0.0001) to the locoregional treatment received and strongly correlated with prognosis. CONCLUSIONS: the update of the present study confirms that tamoxifen is not effective in prolonging survivals, both in advanced patients and in those potentially curable and that the CLIP score is able to predict prognosis.

Isolated anti-HBc in chronic hepatitis C predicts a poor response to interferon treatment.

The sustained response to interferon-alpha treatment was evaluated in 147 anti-HCV/HCV-RNA-positive, HBsAg-negative, chronic hepatitis patients, according to HCV genotypes and the presence or absence of anti-HBs and anti-HBc. These patients had been included in a controlled study on the safety, tolerability, and efficacy of three types of interferon-alpha given at a dose of 3 MU three times weekly for 52 weeks. One hundred and two patients had HCV genotype 1, 42 a non-1 HCV genotype and 3 multiple HCV genotypes; 46 were anti-HBs and anti-HBc negative (group A), 50 anti-HBs and anti-HBc positive (group B), and 51 anti-HBs negative and anti-HBc positive ("isolated" anti-HBc, group C). Serum HBV-DNA was detected by polymerase chain reaction in 15 of the 51 (29.4%) patients in group C and in none of those in groups A or B. The Sustained Response rate was higher in patients with a non-1 HCV genotype than those with HCV genotype 1 (31% vs. 17.7%, P > 0.1). Fewer patients in group C showed a sustained response than in group A or group B (7.8% vs. 30.4%, P = 0.009 and 7.8% vs 28%, P = 0.017, respectively). Moreover, the sustained response rate was high in patients with a non-1 genotype, both in group A (42.8%) and in group B (42.8%), intermediate in patients with HCV genotype 1 (23.3% in group A and 22.2% in group B) and low in group C, irrespective of HCV genotype (8.3% for genotype 1 and 7.1% for other genotypes). The data indicate that patients with HCV chronic hepatitis and isolated anti-HBc show a poor response to IFN-alpha, irrespective of the HCV genotype.

Interferon-alpha plus amantadine in chronic hepatitis C resistant to interferon alone: a pilot randomized study.

The optimal therapy for patients with chronic hepatitis C who have not responded to interferon (IFN) is still an unsolved issue. The aim of this study was to evaluate the efficacy and tolerability of a high dose of IFN-alpha2a plus amantadine for chronic hepatitis C patients who were non-responders to a previous course of IFN. Forty consecutive patients with chronic hepatitis C, genotype 1b, who had not responded to IFN-alpha, were randomized to receive: (i) IFN 4.5 MU daily plus amantadine 200 mg/day for 4 weeks and then IFN 6 MU thrice weekly plus amantadine 200 mg/day for an additional 5 months (group A) or (ii) IFN alone at the same dosage and duration (group B). After 1 month of therapy, normal alanine aminotransferase (ALT) values were observed in three of 21 (14.3%) patients in group A and in three of 19 (15.8%) in group B; serum hepatitis C virus (HCV)-RNA clearance was observed in one patient (4.8%) in group A and in six (31.6%) in group B. At the end of treatment, six patients (28.6%) in group A and three (15.8%) in group B had normal ALT levels; however, HCV-RNA in serum was detectable in all of them at levels comparable to the basal values; an ALT relapse occurred within 3 months of stopping therapy. The combination of daily IFN plus amantadine was ineffective in this setting.

Slowly progressive aphasia associated with surface dyslexia.

We report an Italian patient affected by slowly progressive aphasia (SPA) lasting since four years when he first came to our observation. During the successive four years, we documented a progressive language decline resembling transcortical sensory aphasia, associated with a reading disorder corresponding to surface dyslexia, a form extremely rare in patients with native transparent language. His performance at standard intelligence tasks remained in the normal range, without any variation. CT scan showed left temporal atrophy. We emphasize the heterogeneity of the syndrome of SPA and suggest that it can represent one of the pictures of focal cortical degenerative disease, with variable onset, progression, and evolution.

Short-term memory and verbal learning with auditory phonological coding defect: a neuropsychological case study.

A patient is described with a rarely reported linguistic syndrome: he could repeat words but not nonwords. The patient produced semantic paraphasias in repetition and could read both words and nonwords flawlessly. His basic difficulties were localized in auditory phonological coding, identifying a clinical picture called "phonemic deafness." Short-term memory and verbal learning results suggested that a standard, selective short-term memory defect can be induced by auditory phonological coding deficits as well as by "pure" short-term memory capacity limitation and other phonological deficits. Findings also provided evidence that lexical-semantic code can allow normal verbal learning.

[Huntington chorea. Clinical correlations and preliminary neuropsychological data].

One of the cardinal features of Huntington's disease (HD) is the progressive cognitive deterioration. However, studies carried out on the neuropsychological profile in HD are discordant because there are differences in study designs, stage of disease and because of the coexistence of psychiatric disorders and cultural and educational background of subjects. Aim of this study is to relate the neuropsychological assessment with duration of illness and severity of motor impairment. Fourteen patients are given a neuropsychological battery, the results were statistically related to age and schooling. The data demonstrate very slow progression of cognitive deterioration without focal impairment of cognitive functions and without correlation with the severity of disease.
