Position paper of the Italian Association for the Study of the Liver (AISF): The multidisciplinary clinical approach to hepatocellular carcinoma

Patients with hepatocellular carcinoma should be managed with a multidisciplinary approach framed in a network where all the diagnostic techniques and therapeutic resources are available in order to provide the optimal level of care. Given this assumption, the Coordinating Committee of the Italian Association for the Study of the Liver nominated a panel of experts to elaborate practical recommendations for the multidisciplinary management of hepatocellular carcinoma aiming to provide: (1) homogeneous and efficacious diagnostic and staging work-up, and (2) the best treatment choice tailored to patient status and tumour stage at diagnosis. The 2010 updated American Association for the Study of Liver Disease Guidelines for hepatocellular carcinoma were selected as the reference document. For each management issue, the American Association for the Study of Liver Disease recommendations were briefly summarised and discussed, according to both the scientific evidence published after their release and the clinical expertise of the Italian centres taking care of these patients. The Italian Association for the Study of the Liver expert panel recommendations are finally reported.

Early Menopause Is Associated With Lack of Response to Antiviral Therapy in Women With Chronic Hepatitis C

BACKGROUND & AIMS Chronic hepatitis C (CHC) and liver fibrosis progress more rapidly in men and menopausal women than in women of reproductive age. We investigated the associations among menopause, sustained virologic response (SVR), and liver damage in patients with CHC. METHODS We performed a prospective study of 1000 consecutive, treatment-naïve patients 18 years of age and older with compensated liver disease from CHC. Liver biopsy samples were analyzed (for fibrosis, inflammation, and steatosis) before patients received standard antiviral therapy. From women (n = 442), we collected data on the presence, type, and timing of menopause; associated hormone and metabolic features; serum levels of interleukin-6; and hepatic tumor necrosis factor (TNF)-α. RESULTS Postmenopausal women achieved SVRs less frequently than women of reproductive age (46.0% vs 67.5%; P < .0001) but as frequently as men (51.1%; P = .283). By multivariate regression analysis, independent significant predictors for women to not achieve an SVR were early menopause (odds ratio [OR], 8.055; 95% confidence interval [CI], 1.834-25.350), levels of γ-glutamyl transpeptidase (OR, 2.165; 95% CI, 1.364-3.436), infection with hepatitis C virus genotype 1 or 4 (OR, 3.861; 95% CI, 2.433-6.134), and cholesterol levels (OR, 0.985; 95% CI, 0.971-0.998). Early menopause was the only independent factor that predicted lack of an SVR among women with genotype 1 hepatitis C virus infection (OR, 3.933; 95% CI, 1.274-12.142). Baseline levels of liver inflammation, fibrosis, steatosis, serum interleukin-6 (P = .04), and hepatic TNF-α (P = .007) were significantly higher among postmenopausal women than women of reproductive age. CONCLUSIONS Among women with CHC, early menopause was associated with a low likelihood of SVR, probably because of inflammatory factors that change at menopause.

Reproductive status is associated with the severity of fibrosis in women with hepatitis C.

Introduction Chronic hepatitis C is the main cause of death in patients with end-stage liver disease. Prognosis depends on the increase of fibrosis, whose progression is twice as rapid in men as in women. Aim of the study was to evaluate the effects of reproductive stage on fibrosis severity in women and to compare these findings with age-matched men. Materials and Methods A retrospective study of 710 consecutive patients with biopsy-proven chronic hepatitis C was conducted, using data from a clinical database of two tertiary Italian care centers. Four age-matched groups of men served as controls. Data about demographics, biochemistry, liver biopsy and ultrasonography were analyzed. Contributing factors were assessed by multivariate logistic regression analysis. Results Liver fibrosis was more advanced in the early menopausal than in the fully reproductive (P<0.0001) or premenopausal (P = 0.042) group. Late menopausal women had higher liver fibrosis compared with the other groups (fully reproductive, P<0.0001; premenopausal, P = <0.0001; early menopausal, P = 0.052). Multivariate analyses showed that male sex was independently associated with more severe fibrosis in the groups corresponding to premenopausal (P = 0.048) and early menopausal (P = 0.004) but not late menopausal pairs. In women, estradiol/testosterone ratio decreased markedly in early (vs. reproductive age: P = 0.002 and vs. premenopausal: P<0.0001) and late menopause (vs. reproductive age: P = 0.001; vs. premenopausal: P<0.0001). In men age-matched with menopausal women, estradiol/testosterone ratio instead increased (reproductive age group vs. early: P = 0.002 and vs. late M: P = 0.001). Conclusions The severity of fibrosis in women worsens in parallel with increasing estrogen deprivation and estradiol/testosterone ratio decrease. Our data provide evidence why fibrosis progression is discontinuous in women and more linear and severe in men, in whom aging-associated estradiol/testosterone ratio increase occurs too late to noticeably influence the inflammatory process leading to fibrosis.

De novo malignancies following liver transplantation: results from a multicentric study in central and southern Italy, 1990-2008.

OBJECTIVE The objective of this study was to quantify incidence rates (IR) and risks of de novo tumors (except nonmelanoma skin cancers) in patients who underwent orthotopic liver transplantation (OLT) in central and southern Italy. METHODS Data were collected on 1675 patients (75.5% males) who underwent OLT in six Italian transplantation centers in central and southern Italy (1990-2008). The time at risk of cancer (person years [PY]) was computed from OLT to the date of cancer diagnosis, death, or last follow-up, whichever occurred first. The number of observed cancer cases were compared with the expected one using data from population-based cancer registries. We computed gender- and age-standardized incidence ratios (SIRs) and 95% confidence intervals (CIs). RESULTS During 10,104.3 PYs (median follow-up, 5.2 years), 98 patients (5.9% of the total) were diagnosed with a de novo malignancy (for a total of 100 diagnoses). Twenty-two of these cancers were post-transplantation lymphoproliferative disorders (PTLD; 18 non-Hodgkin lymphoma [NHL] and 2 Hodgkins lymphoma [HL]), 6 were Kaposis sarcoma (KS), and 72 were solid tumors (19 head and neck [H&N], 13 lung, 11 colon-rectum, 6 bladder, and 4 melanoma). The overall incidence was 9.9 cases/10(3) PYs, with a 1.4-fold significantly increased SIR (95% CI, l.2-1.7). Significantly increased SIRs were observed for KS (37.3), PTLD (3.9), larynx (5.7), melanoma (3.1), tongue (7.1), and H&N (4.5) cancers. CONCLUSIONS These results confirmed that OLT patients are at greater risk for cancer, mainly malignancies either virus-associated or related to pre-existent factors (eg, alcohols). These observations point to the need to improve cancer surveillance after OLT. The on-going enrollment of patients in the present cohort study will help to elucidate the burden of cancer after OLT and better identify risk factors associated with its development.

Mycophenolate mofetil in the treatment of autoimmune HCV‐associated haematological disorders showing steroid resistance or dependence

Summary. We report two cases of hepatitis C virus (HCV) associated autoimmune haematological disorders successfully treated with an unusual protocol (mycophenolate mofetil: MMF). The first case was a male patient with chronic HCV infection who developed, during interferon (IFN)/ribavirin therapy, severe autoimmune thrombocytopenia unresponsive to steroids. MMF was then administered and, simultaneously, the steroid dose was gradually reduced until withdrawal. Following this strategy, a progressive increase in platelet count and complete negativity of anti‐PLT antibodies were achieved without changes in HCV‐RNA quantitative determination. The second case was a woman with HCV liver cirrhosis with severe anaemia and Coombs test positivity partially responsive to continuous administration of steroid high doses. However, this treatment unmasked a severely painful vertebral osteoporosis. For this reason we introduced MMF and simultaneously steroid therapy was progressively reduced until withdrawal. Haemoglobin reached a normal value and the Coombs test became negative within 60 days. These case reports suggest that MMF may represent an interesting therapeutic approach for autoimmune HCV associated haematological disorders.

Hepatitis C in the elderly: A multicentre cross-sectional study by the Italian Association for the Study of the Liver

BACKGROUND The prevalence of hepatitis C virus infection increases with advancing age, but elderly hepatitis C virus patients remain an understudied population. AIM To define the virological, epidemiological and clinical profiles of Italian outpatients aged 65 years and over infected by hepatitis C virus. METHODS We evaluated 1544 anti-hepatitis C virus positive patients aged ≥65 years referred to 34 Italian outpatient specialty clinics over a two-year period. RESULTS The study population included 1134 (73%) early elderly (65-74 years) and 410 (27%) late elderly patients (≥75 years). Late elderly subjects were less likely to have their virus genotyped, their viral load assessed or a histological evaluation of liver disease. Overall, 30% of patients had advanced liver disease whose prevalence increased with increasing age. In both age groups, about 40% of patients had normal transaminase levels. Excluding patients with past infection, 51% had not received any antiviral treatment and only 25% were treated after the age of 65. Late elderly patients, women and patients with advanced liver diseases had been less frequently treated. The main reason for exclusion from treatment was age followed by the presence of comorbid conditions. CONCLUSIONS Elderly hepatitis C virus patients referred to Italian specialty clinics have advanced and underestimated liver disease. Nevertheless, they are progressively understudied in parallel with increasing age.

Triple therapy with first-generation protease inhibitors for patients with genotype 1 chronic hepatitis C: recommendations of the Italian association for the study of the liver (AISF).

The first-generation Protease Inhibitors Boceprevir and Telaprevir administered in triple therapy regimens with Peg-interferon alpha and Ribavirin have been proven effective in increasing the rate of Sustained Virological Response in both naive and treatment-experienced patients with chronic genotype-1 hepatitis C. However, at the individual level, the therapeutic advantage of triple therapy is highly variable and results from the combination of multiple factors related to the characteristics of patient, viral status and liver disease. The recommendations presented are promoted by the Italian Association for the Study of the Liver, with the aim to help the physician in the decision-making process as well as to manage patients during treatment with triple therapy.

Long-term albumin administration in decompensated cirrhosis (ANSWER): an open-label randomised trial

BACKGROUND Evidence is scarce on the efficacy of long-term human albumin (HA) administration in patients with decompensated cirrhosis. The human Albumin for the treatmeNt of aScites in patients With hEpatic ciRrhosis (ANSWER) study was designed to clarify this issue. METHODS We did an investigator-initiated multicentre randomised, parallel, open-label, pragmatic trial in 33 academic and non-academic Italian hospitals. We randomly assigned patients with cirrhosis and uncomplicated ascites who were treated with anti-aldosteronic drugs (≥200 mg/day) and furosemide (≥25 mg/day) to receive either standard medical treatment (SMT) or SMT plus HA (40 g twice weekly for 2 weeks, and then 40 g weekly) for up to 18 months. The primary endpoint was 18-month mortality, evaluated as difference of events and analysis of survival time in patients included in the modified intention-to-treat and per-protocol populations. This study is registered with EudraCT, number 2008-000625-19, and ClinicalTrials.gov, number NCT01288794. FINDINGS From April 2, 2011, to May 27, 2015, 440 patients were randomly assigned and 431 were included in the modified intention-to-treat analysis. 38 of 218 patients died in the SMT plus HA group and 46 of 213 in the SMT group. Overall 18-month survival was significantly higher in the SMT plus HA than in the SMT group (Kaplan-Meier estimates 77% vs 66%; p=0·028), resulting in a 38% reduction in the mortality hazard ratio (0·62 [95% CI 0·40-0·95]). 46 (22%) patients in the SMT group and 49 (22%) in the SMT plus HA group had grade 3-4 non-liver related adverse events. INTERPRETATION In this trial, long-term HA administration prolongs overall survival and might act as a disease modifying treatment in patients with decompensated cirrhosis.

Treatment of hepatitis C recurrence is less successful in female than in male liver transplant recipients

It has been recently suggested that the risk of graft loss after liver transplantation (LT) may increase in female HCV patients. The aim of the study was to examine gender differences in HCV therapy tolerance and outcome in LT patients treated for HCV recurrence. A retrospective study was conducted on liver recipients with HCV recurrence, who were given antiviral therapy from 2001 to 2009 in 12 transplant centers in Italy. Sustained virological response (SVR), adherence‐to‐therapy, and side effects were evaluated. A multivariate logistic regression model was used after adjusting for possible confounders. The data regarding 342 treated patients were analyzed. SVR was reported in 38.8% of patients. At baseline, male and female did not differ in HCV viral load, histology, or rate of diabetes. SVR was lower in females than in males (29.5% vs. 42.1%; P = 0.03). Adherence‐to‐therapy was also lower in females than in males 43.4% vs. 23.8%; P = 0.001); anemia was the main reason for lower adherence. In a multivariate analysis in patients Genotype 1, female gender (P < 0.04), early virological response (P < 0.0001), and adherence to therapy (P < 0.0001) were independent predictors for SVR. In conclusion, female gender represents an independent negative prognostic factor for the outcome of HCV antiviral therapy after LT.
