Abstract
BACKGROUND Asunaprevir is a selective NS3 protease inhibitor with in vitro activity against HCV genotypes 1 and 4. METHODS In this Phase IIa double-blind study, treatment-naive HCV genotype-1-infected patients in the United States and France were randomly assigned 1:1:1:1 to placebo or asunaprevir 200 mg twice daily, 600 mg twice daily or 600 mg once daily in combination with pegylated interferon (PEG-IFN)-α2a and ribavirin for 48 weeks. The primary efficacy end point was undetectable HCV RNA at weeks 4 and 12 (extended rapid virological response [eRVR]). Other end points included safety and undetectable HCV RNA at 24 weeks post-treatment (24-week sustained virological response [SVR24]). RESULTS A total of 47 patients were randomized and treated. eRVR was achieved by 75% (9/12), 75% (9/12) and 92% (11/12) of patients in the asunaprevir 200 mg twice-daily, 600 mg twice-daily and 600 mg once-daily groups, respectively, versus 0% (0/11) in the placebo group. Corresponding SVR24 rates were 83% (10/12), 83% (10/12) and 92% (11/12) in the asunaprevir groups and 46% (5/11) in the placebo group. There was no virological breakthrough in any asunaprevir group. Following the 12-week analysis, the 600 mg doses were reduced to 200 mg twice daily because of a greater frequency of transaminase elevations at the 600 mg dose. The most common grade 3-4 laboratory abnormalities were consistent with those reported for PEG-IFN and ribavirin. CONCLUSIONS Asunaprevir plus PEG-IFN and ribavirin achieved higher response rates than placebo plus PEG-IFN and ribavirin, with a tolerable adverse event profile at the 200 mg twice-daily dose. This dose is being evaluated in the Phase IIb and Phase III studies.

Abstract
UNLABELLED Faldaprevir (BI 201335) is a potent, hepatitis C virus (HCV) NS3/4A protease inhibitor. In all, 290 noncirrhotic HCV genotype (GT)-1 patients with prior null (<1 log10 viral load [VL] drop at any time on treatment) or partial response (≥1 log10 VL drop but never undetectable on treatment) were randomized 2:1:1 to receive 48 weeks of peginterferon alfa-2a and ribavirin (PegIFN/RBV) in combination with faldaprevir 240 mg once daily (QD) with 3 days PegIFN/RBV lead-in (LI), 240 mg QD without LI, or 240 mg twice daily (BID) with LI. Patients in the 240 mg QD/LI group achieving maintained rapid virologic response (mRVR; VL <25 IU/mL [Roche TaqMan] at week 4 and undetectable at weeks 8 to 20) were rerandomized to cease all treatment at week 24 or continue PegIFN/RBV up to week 48. Sustained virologic response (SVR) rates were 32%, 50%, and 42% in prior partial responders, and 21%, 35%, and 29% in prior null responders in the faldaprevir 240 mg QD/LI, 240 mg QD, and 240 mg BID/LI groups, respectively. In the 240 mg QD/LI group, a significantly higher proportion of mRVR patients rerandomized to 48 weeks' treatment achieved SVR compared with those assigned to 24 weeks treatment (72% versus 43%; P = 0.035). Rates of gastrointestinal disorders, jaundice, dry skin, and photosensitivity were increased at 240 mg BID compared with the 240 mg QD dose. Faldaprevir discontinuations owing to adverse events occurred in 6%, 4%, and 23% of patients in the 240 mg QD/LI, 240 mg QD, and 240 mg BID/LI groups, respectively. CONCLUSION Faldaprevir 240 mg QD with PegIFN/RBV was safe and tolerable and produced substantial SVR rates in prior null and partial responders. The 240 mg QD dose is currently undergoing phase 3 evaluation.

Abstract
BACKGROUND Faldaprevir (BI 201335) and deleobuvir (BI 207127) are direct-acting antiviral agents under development for the treatment of chronic HCV infection. This article describes the final results of the Phase Ib SOUND-C1 study that evaluated the interferon-free oral combination of faldaprevir, deleobuvir and ribavirin in 32 treatment-naive patients infected with HCV genotype 1. METHODS Patients were randomized to receive deleobuvir 400 mg (n=15) or 600 mg (n=17) three times daily plus faldaprevir 120 mg once daily and weight-based ribavirin for 4 weeks. Interferon-free therapy was followed by response-guided faldaprevir plus pegylated interferon-α2a/ribavirin to week 24 or 48. RESULTS At week 4, 73% (11/15) and 100% (17/17) of patients in the deleobuvir 400 mg and 600 mg groups achieved HCV RNA<25 IU/ml, respectively. During interferon-free treatment, virological breakthrough was reported in one patient and re-increase of HCV RNA in one patient. Both patients were successfully treated with interferon-containing therapy. The rate of sustained virological response 24 weeks after completion of treatment was 73% (11/15) in the deleobuvir 400 mg group and 94% (16/17) in the 600 mg group. During faldaprevir plus pegylated interferon-α2a/ribavirin treatment, the most common adverse events were pruritus (38% of patients), rash (31%) and asthenia (31%); these were severe in approximately 3% of patients. CONCLUSIONS Potent antiviral activity and favourable safety of the treatment regimen were demonstrated. Furthermore, the results suggest that patients with breakthrough at week 4 may be rescued with an interferon-containing regimen. Clinical trials.gov number NCT01132313.

Abstract
Hepatitis C virus (HCV) infected patients often take multiple co-medications to treat adverse events related to HCV therapy, or to manage other co-morbidities. Drug-drug interactions associated with this polypharmacy are relatively new to the field of HCV pharmacotherapy. With the advent of the direct-acting antivirals telaprevir and boceprevir, which are both substrates and inhibitors of the cytochrome P450 (CYP) 3A iso-enzyme, knowledge and awareness of drug-drug interactions have become a cornerstone in the evaluation of patients starting and continuing HCV combination therapy. In our opinion, an overview of conducted drug-drug interaction studies and a list of contraindicated medications is not enough for the clinical management of these drug-drug interactions. Knowledge of pharmacokinetic profiles and concentration-effect relationships is key for the interpretation of these data, and insight into how to manage these interactions (e.g., dose adjustments, safe alternatives and therapeutic drug monitoring) is of equal importance. This review provides a practical overview of the safe and effective management of these clinical challenges.

Abstract
PURPOSE The European Committee for Human Medicinal Products (CHMP) requested a multinational study with the aim to investigate the risk of acute liver failure (ALF) leading to registration for transplantation in patients exposed to non-steroidal anti-inflammatory drugs (NSAIDs). The method of this multinational, multicentre, retrospective case-population study, named SALT (Study of Acute Liver Transplant), is documented here. METHODS This was a multicentre, multinational retrospective case-population study performed in France, Italy, Portugal, Greece, Ireland, the Netherlands and the UK. The study period was 3 years (1 January 2005-31 December 2007). Cases were patients ≥ 18 years of age with ALF at the time of registration on the transplant list for liver transplantation who had been exposed to an NSAID within 30 days preceding the initial symptoms of liver disease (index date). Exposure was defined as exposure to any NSAID. Per country rates of NSAID-exposed transplantation-registered ALF were computed as the ratio of the number of cases identified in the country to total population exposure. Overall and per-drug sales for NSAIDs and for paracetamol were obtained from Intercontinental Marketing Services (IMS) Health for all participating countries. Population exposure was measured as the defined daily dose and as estimated annual number of patients exposed (primary endpoint) with 95 % confidence intervals. RESULTS The study protocol was approved by the CHMP. Of the 57 eligible liver transplant centres, 54 agreed to participate in the study. All national authorizations were received with relevant administrative burden, mainly due to bureaucracy. CONCLUSION The present study created a multinational research network to estimate population-based absolute rates of drug-exposed ALF leading to registration on the transplantation list. This study design was chosen to obtain a fast response to a public health issue, namely, that of an increased risk of a rare, very serious adverse reaction. This model could be used to study other drug-related issues in ALF.

Abstract
BACKGROUND & AIMS Beyond 5 years, poorer survival, related to alcohol relapse, is observed in patients with liver transplant for alcohol-related liver disease (ALD). However, alcohol consumption has been significantly understudied in non-ALD transplant recipients. We aimed at analyzing the impact of alcohol consumption on long-term survival irrespective of the indication for transplantation. METHODS This observational study included consecutive adult recipients of a primary liver graft between 1991 and 2007 in our hospital, who survived >6 months. Patients without ALD as primary indication, but with a history of excessive alcohol consumption before transplantation, were classified as secondary indication ALD. We studied the impact on survival of excessive consumption of alcohol after transplantation and several other variables. RESULTS The 441 patients had mean follow-up of 81.7 months. Among the 281 patients with excessive alcohol consumption before transplantation, 206 had ALD as primary indication. After transplantation, alcohol consumption was reported by 32.3% of the study population, 43.7% in primary indication ALD, and 24.3% in non-ALD patients. Survival was 82% at 5 years and 49% at 10 years for patients with excessive alcohol relapse, compared with 86% and 75%, respectively, for patients without persistent excessive alcohol relapse. By multivariable analysis, the independent risk factors of death were: excessive alcohol relapse, age >51 years, post-transplantation diabetes mellitus, cyclosporine-based immunosuppression, and non-hepatic cancer. CONCLUSIONS Excessive alcohol consumption has a negative impact on long-term survival after liver transplant, irrespective of the primary indication. Death is mainly due to recurrence of liver disease and non-hepatic cancer.

Abstract
BACKGROUND & AIMS Blood tests and transient elastography (Fibroscan™) have been developed as alternatives to liver biopsy. This ANRS HCEP-23 study compared the diagnostic accuracy of nine blood tests and transient elastography (Fibroscan™) to assess liver fibrosis, vs. liver biopsy, in untreated patients with chronic hepatitis C (CHC). METHODS This was a multicentre prospective independent study in 19 French University hospitals of consecutive adult patients having simultaneous liver biopsy, biochemical blood tests (performed in a centralized laboratory) and Fibroscan™. Two experienced pathologists independently reviewed the liver biopsies (mean length=25±8.4 mm). Performance was assessed using ROC curves corrected by Obuchowski's method. RESULTS Fibroscan™ was not interpretable in 113 (22%) patients. In the 382 patients having both blood tests and interpretable Fibroscan™, Fibroscan™ performed similarly to the best blood tests for the diagnosis of significant fibrosis and cirrhosis. Obuchowski's measure showed Fibrometer® (0.86), Fibrotest® (0.84), Hepascore® (0.84), and interpretable Fibroscan™ (0.84) to be the most accurate tests. The combination of Fibrotest®, Fibrometer®, or Hepascore® with Fibroscan™ or Apri increases the percentage of well classified patients from 70-73% to 80-83% for significant fibrosis, but for cirrhosis a combination offers no improvement. For the 436 patients having all the blood tests, AUROC's ranged from 0.82 (Fibrometer®) to 0.75 (Hyaluronate) for significant fibrosis, and from 0.89 (Fibrometer® and Hepascore®) to 0.83 (FIB-4) for cirrhosis. CONCLUSIONS Contrarily to blood tests, performance of Fibroscan™ was reduced due to uninterpretable results. Fibrotest®, interpretable Fibroscan™, Fibrometer®, and Hepascore® perform best and similarly for diagnosis of significant fibrosis and cirrhosis.

Abstract
BACKGROUND & AIMS Therapeutic regimens are being developed for patients with hepatitis C virus (HCV) infection that do not include the combination of peginterferon alfa and ribavirin. We investigated the antiviral effect and safety of BI 201335 (an inhibitor of the NS3/4A protease) and BI 207127 (an inhibitor of the NS5B non-nucleoside polymerase) with ribavirin. METHODS Thirty-two treatment-naïve patients with chronic HCV genotype 1 infection were randomly assigned to groups that were given 400 mg or 600 mg BI 207127 3 times daily plus 120 mg BI 201335 once daily and 1000 to 1200 mg/day ribavirin for 4 weeks. The primary efficacy end point was virologic response (HCV RNA level <25 IU/mL at week 4). Thirty-two patients received treatment; 31 completed all 4 weeks of assigned combination therapy. RESULTS In the group given BI 207127 400 mg 3 times daily, the rates of virologic response were 47%, 67%, and 73% at days 15, 22, and 29; a higher rate of response was observed in patients with genotype-1b compared with genotype-1a infections. In the group given BI 207127 600 mg 3 times daily, the rates of virologic response were 82%, 100%, and 100%, respectively, and did not differ among genotypes. One patient in the group given 400 mg 3 times daily had virologic breakthrough (≥1 log(10) rebound in HCV RNA) at day 22. The most frequent adverse events were mild gastrointestinal disorders, rash, and photosensitivity. There were no severe or serious adverse events; no patients discontinued therapy prematurely. CONCLUSIONS The combination of the protease inhibitor BI 201335, the polymerase inhibitor BI 207127, and ribavirin has rapid and strong activity against HCV genotype-1 and did not cause serious or severe adverse events.

Abstract
BACKGROUND Current therapy options for patients with chronic hepatitis C virus (HCV) infection genotype 1 are effective in <50%. Danoprevir (ITMN-191/RG7227) is a potent, selective, and orally active inhibitor of the HCV NS3/4A serine protease. METHODS The safety and antiviral efficacy of danoprevir was examined over 14 days in combination with pegylated interferon α-2a (180 μg once weekly) and ribavirin (1000-1200 mg/day) in a double-blind, placebo-controlled, phase 1b, multiple ascending dose study consisting of 6 dose cohorts (400 mg, 600 mg, and 900 mg twice daily and 100 mg, 200 mg, and 300 mg 3 times daily). RESULTS Danoprevir in combination with pegylated interferon α-2a and ribavirin was safe and generally well tolerated. The median change in HCV RNA level from baseline to the end of treatment with danoprevir at 400 mg, 600 mg, and 900 mg twice daily was -4.7 log(10) IU/mL, -5.4 log(10) IU/mL, and -5.3 log(10) IU/mL, respectively, and at 100 mg, 200 mg, and 300 mg 3 times daily was -5.5 log(10) IU/mL, -5.7 log(10) IU/mL, and -5.6 log(10) IU/mL, respectively. Placebo administered in combination with standard of care resulted in median decrease in HCV RNA level of -2.6 log(10) IU/mL (with twice daily regimen) and -2.0 log(10) IU/mL (with 3 times daily regimen). CONCLUSIONS Our study showed substantial antiviral efficacy of danoprevir in combination with pegylated interferon α-2a and ribavirin. Exploration of the safety and antiviral efficacy of danoprevir in longer clinical studies is warranted.

Abstract
BACKGROUND & AIMS Education of patients with chronic hepatitis C has been proposed to increase response to therapy with peginterferon and ribavirin. We performed a prospective study to determine the effects of systematic consultation by a nurse on patient adherence and the efficacy of therapy. METHODS We analyzed data from 244 patients who received either systematic consultation after each medical visit from a nurse who used a standard evaluation grid and provided information about the disease and treatment (group A [GrA], n = 123) or the conventional clinical follow-up procedure (group B [GrB], n = 121). Treatment lasted 24 to 48 weeks. RESULTS Characteristics of each group were similar at baseline, including prior treatment (42.6% in GrA and 36.0% in GrB). Overall, GrA had significantly better adherence to treatment than GrB (74.0% vs 62.8%), especially among patients who received 48 weeks of treatment (69.7% vs 53.2%; P < .03). Significantly more patients in GrA had a sustained virologic response, compared with GrB overall (38.2% vs 24.8%; P < .02), as well as treatment-naive patients (47.1% vs 30.3%; P < .05), and those with genotypes 1, 4, or 5 infections (31.6% vs 13.3%; P < .007). There were no differences between GrA and GrB in response of patients with genotypes 2 or 3 infections or advanced fibrosis. Prognostic factors for a sustained virologic response (based on bivariate and multivariate analyses) were virologic response at week 12 (odds ratio [OR], 1.9; P < .0001), genotypes 2 or 3 (OR, 2.9; P < .0001), therapeutic education (OR, 2.5; P < .02), and lack of previous treatment (OR, 2.3; P < .005). CONCLUSIONS Therapeutic education by a specialized nurse increases the response of patients with hepatitis C to therapy, particularly in difficult-to-treat patients.

Abstract
BACKGROUND The most specific indicator of a drug-induced liver injury signal in a clinical trial database is believed to be the occurrence of subjects experiencing drug-associated elevations in both serum ALT and serum total bilirubin (TB) without a significant elevation in serum alkaline phosphatase (ALP). eDISH (evaluation of Drug-Induced Serious Hepatotoxicity) is a recently described tool that organizes liver laboratory data by graphically displaying peak serum ALT and TB levels for each subject, and can also provide direct links to the pertinent clinical and laboratory data for each subject. OBJECTIVE To illustrate the usefulness of the eDISH approach in the presentation of liver safety data by using phase III clinical trial data for rivaroxaban. METHODS Four randomized, active-controlled studies were conducted worldwide in subjects undergoing elective hip or knee replacement surgery to compare the efficacy and safety of the anticoagulant rivaroxaban, an oral, direct Factor Xa inhibitor, with the low-molecular-weight heparin, enoxaparin. Liver laboratory assessments, including ALT, AST, TB and ALP, were performed frequently during the studies. Data were incorporated into eDISH and linked data for selected subjects were analysed. RESULTS In the pooled analysis of the four studies, a total of 12 262 subjects (6131 rivaroxaban, 6131 enoxaparin) received at least one dose of study drug and had at least one central and/or local laboratory assessment during the study. A total of 143 (2.33%) rivaroxaban subjects and 223 (3.64%) enoxaparin subjects experienced a peak ALT >3 × upper limit of normal (ULN) but did not experience an elevation of TB >2 × ULN; these subjects are displayed in the right lower quadrant of the eDISH plot, termed the 'Temple's Corollary quadrant'. There were ten rivaroxaban and ten enoxaparin subjects with a peak ALT >3 × ULN and a peak TB >2 × ULN; these subjects were displayed in the right upper quadrant of the eDISH plot, termed the 'Hy's Law quadrant'. eDISH allowed efficient examination of the relevant data for each of these subjects. CONCLUSIONS The eDISH approach is an efficient and effective way to organize and examine large liver safety databases for randomized controlled clinical trials. It greatly facilitates a systematic and transparent examination of the relevant liver safety laboratory data. We believe eDISH should become a standard approach for assessing and studying liver safety issues in clinical trials.

Abstract
BACKGROUND & AIMS Danoprevir is a potent and selective inhibitor of the hepatitis C virus (HCV) NS3/4A serine protease. The present study assessed the safety, pharmacokinetics, and antiviral activity of danoprevir in a randomized, placebo-controlled, 14-day multiple ascending dose study in patients with chronic HCV genotype 1 infection. METHODS Four cohorts of treatment-naïve (TN) patients (100 mg q12 h, 100 mg q8 h, 200 mg q12 h, 200 mg q8 h) and one cohort of non-responders (NR) to prior pegylated interferon alfa-ribavirin treatment (300 mg q12 h) were investigated. RESULTS Danoprevir was safe and well tolerated; adverse events were generally mild, transient and were not associated with treatment group or dose level. Danoprevir displayed a slightly more than proportional increase in exposure with increasing daily dose and was rapidly eliminated from the plasma compartment. Maximal decreases in HCV RNA were: -3.9 log(10)IU/ml and -3.2 log(10)IU/ml in TN receiving 200 mg q8 h and 200 mg q12 h, respectively. End of treatment viral decline in these two cohorts was within 0.1 log(10)IU/ml of the viral load nadir. HCV RNA reduction in NR was more modest than that observed in upper dose TN cohorts. The overall incidence of viral rebound was low (10/37) and was associated with the R155K substitution in NS3 regardless of the HCV subtype. CONCLUSIONS Danoprevir was safe and well tolerated when administered for 14 days in patients with chronic HCV genotype 1 infection. Treatment resulted in sustained, multi-log(10) IU/ml reductions in HCV RNA in upper dose cohorts. These results support further clinical evaluation of danoprevir in patients with chronic HCV.

Abstract
BACKGROUND/AIM Insulin resistance (IR) is a major predictor of treatment failure in patients with hepatitis C virus (HCV) infection treated with peginterferon/ribavirin. The aim of this study was to evaluate the short-term effect of an HCV protease inhibitor monotherapy on IR in parallel with an antiviral effect. PATIENTS/METHODS In a phase 1b placebo-controlled study, four cohorts of treatment-naïve patients with genotype 1 HCV received danoprevir (ITMN-191/RG7227), a protease inhibitor, or placebo (8/2 patients in each cohort respectively) in a gelatin capsule every 12 h (100, 200 mg) or 8 h (100, 200 mg) for 14 days. A fifth cohort including prior non-responders to peginterferon/ribavirin was similarly randomised to receive placebo or 300 mg danoprevir every 12 h. IR was assessed with the homeostasis model (HOMA-IR) at baseline and days 7, 14 and 15. RESULTS Serum HCV-RNA and HOMA-IR correlated significantly (Spearman rho=0.379, p<0.0001). At baseline, mean±SD serum HCV-RNA level and mean±SD HOMA-IR score were 6.2±0.5 log(10) IU/ml and 3.8±1.9, respectively. At the end of 14 days of monotherapy the mean±SD decrease in viral load was 2.2±1.3 log(10) IU/ml (p<0.0001) in patients who received the active drug (n=40). In parallel, the mean±SD HOMA-IR score also decreased in these patients by 1.6±1.1 (p<0.0001), with a close correlation between the extent of HOMA-IR improvement and the decrease in viral load. By contrast, serum HCV-RNA and HOMA-IR remained unchanged in patients who received placebo (n=10; 6.3±0.5 log(10) IU/ml and 3.8±2.5, respectively). CONCLUSION HCV protease inhibitor may restore insulin sensitivity in patients with genotype 1 HCV. The place of insulin sensitisers remains to be determined in the era of triple therapy.

Abstract
BACKGROUND & AIMS Nonalcoholic steatohepatitis (NASH) is a prevalent liver disease associated with increased morbidity and mortality. Ursodeoxycholic acid (UDCA) may have antioxidant, anti-inflammatory, and antifibrotic properties and may reduce liver injury in NASH. To date, no studies have assessed the efficacy and safety of high-dose UDCA (HD-UDCA) in patients with NASH. METHODS We conducted a 12-month, randomized, double-blind, placebo-controlled multicenter trial to evaluate the efficacy and safety of HD-UDCA (28-35 mg/kg per day) in 126 patients with biopsy-proven NASH and elevated alanine aminotransferase (ALT) levels. The primary study end point was reduction in ALT levels from baseline in patients treated with HD-UDCA compared with placebo. Secondary study end points were the proportion of patients with ALT normalization, relative reduction in the scores of serum markers of fibrosis and hepatic inflammation, and safety and tolerability. RESULTS HD-UDCA significantly reduced mean ALT levels -28.3% from baseline after 12 months compared with -1.6% with placebo (p<0.001). At the end of the trial, ALT levels normalized (≤35 IU/L) in 24.5% of patients treated with HD-UDCA and in 4.8% of patients who received placebo (p=0.003). Both results were not accounted for by changes in weight during the trial. HD-UDCA significantly reduced the FibroTest® serum fibrosis marker (p<0.001) compared with placebo. HD-UDCA also significantly improved markers of glycemic control and insulin resistance. There were no safety issues in this population. CONCLUSIONS Treatment with HD-UDCA was safe, improved aminotransferase levels, serum fibrosis markers, and selected metabolic parameters. Studies with histologic end points are warranted.

Abstract
AIM: To evaluate the prevalence of breast tumors in adult females with chronic hepatitis C virus (HCV) infection.
METHODS: Prospective, single-center study, based on female outpatients consulting in a liver unit, for 1 year. The study group included females with present and/or past history of chronic infection by HCV. Patients with spontaneous recovery were excluded. Chronic hepatitis had been proved by liver biopsy in the majority of cases and/or biological markers of inflammation and fibrosis. The control group included female patients with other well documented chronic liver diseases: chronic hepatitis B, alcoholic liver disease, autoimmune hepatitis, hemochromatosis, non alcoholic liver disease, chronic cholangitis. Participating patients were prospectively questioned during consultation about past breast history and follow-up by mammography.
RESULTS: Breast carcinoma was recorded in 17/294 patients with HCV infection (5.8%, 95% CI: 3.1-8.4) vs 5/107 control patients (4.7%, 95% CI: 0.67-8.67). Benign tumors of the breast (mastosis, nodules, cysts) were recorded in 75/294 patients with HCV infection (25.5%, 95% CI: 20.5-30.5) vs 21/107 (19.6%, 95% CI: 12.1-27.1) in the control group. No lesion was noted in 202 patients with HCV (68.7%, 95% CI: 63.4-74) vs 81 control patients (75.7%, 95% CI: 67.6-83.8). Despite a trend to an increased prevalence in the group with HCV infection, the difference was not significant compared to the control group (P = NS). In patients over 40 years, the results were, respectively, as follows: breast cancer associated with HCV: 17/266 patients (6.3%, 95% CI: 3.4-9.3) vs 5/95 patients (5.2%, 95% CI: 0.7-9.7) in the control group; benign breast tumors: 72/266 patients with HCV infection (27%, 95% CI: 21.7-32.4) vs 18/95 patients (18.9%, 95% CI: 11-26.8) in the control group; no breast lesion 177/266 (66.5%, 95% CI: 60.9-72.2) in patients with HCV infection vs 72/95 (75.7%, 95% CI: 67.1-84.4) in the control group. The differences were not significant (P = NS).
CONCLUSION: These results suggest that chronic HCV infection is not a strong promoter of breast carcinoma in adult females of any age.

Abstract
BACKGROUND Despite great progress in understanding the mechanisms underlying genetic hemochromatosis, data on the prevalence and the penetrance of the disorder are conflicting. DESIGN AND METHODS A registry of patients with genetic hemochromatosis was established in the South of France and a regional health network was developed to allow the inclusion of all the diagnosed patients. C282Y homozygous patients classified in stages 2 (biological iron overload), 3 and 4 (clinical manifestations of iron overload, stage 4 being the more severe) according to the classification of the French National Authority for Health were included in the registry over a 6-year period. RESULTS A total of 352 symptomatic C282Y homozygotes were identified, resulting in a total prevalence of 1.83 per 10,000 (95% CI: 1.63 to 2.02) in subjects over 20 years and 2.40 per 10,000 (95% CI, 2.15 to 2.65) among subjects of European descent. Among Europeans, the total calculated penetrance was 15.8% in stage 2 or higher, 12.1% in stage 3 or 4 and 2.9% in stage 4. The penetrance was slightly higher in males (18.7%) than in females (13.2%). It was 19.9% for individuals over 40 years of age (24.1% and 16.3% in males and females, respectively) with a maximum of 31% in subjects between 50 and 54 years old. Among 249 patients with complete records, 24% were in stage 2, the majority (58%) were in stage 3, and 18% in stage 4. There was a higher proportion of males, and excessive alcohol intake was more prevalent in stage 4 than in stages 2 and 3 combined. CONCLUSIONS A French Mediterranean regional hemochromatosis registry with strict inclusion criteria is a useful tool for characterizing the history of this disease, particularly for the most severely affected patients, as defined by the disease severity classification. The total prevalence of symptomatic C282Y homozygotes in the region was found to be low. However, clinical penetrance (stages 3 and 4) was not negligible.
