Therapeutic options in hepatitis C virus (HCV)-related vasculitis may target the viral trigger using antiviral therapy [pegylated interferon plus ribavirin (PEG-IFN/RBV)], and/or the downstream B-cell arm of autoimmunity with rituximab (RTX). To date, no study has compared the efficacy of RTX combined with PEG-IFN/RBV on biomarkers of liver insufficiency in patients with severe liver fibrosis. Twenty-eight untreated HCV-related vasculitis patients with severe liver fibrosis (Metavir F3-F4) were included: 14 patients received RTX plus PEG-IFN/RBV and 14 patients PEG-IFN/RBV. The main clinical and biological data were recorded and compared at baseline, month 3 (M3), M12 and M24 of follow-up. Baseline epidemiological, clinical, virological and immunological features were similar between the groups. The virological response did not differ between cases and controls. The alanine aminotransferase (ALT) level and HCV viral load did not increase in patients treated with RTX. Serum albumin levels increased in patients treated with RTX at M3 and M6 (108% and 111% of baseline value; P = 0.06 and P = 0.13), whereas it was stable in patients treated without RTX. FibroTest values decreased from 0.70 at baseline to 0.59 at M3 (P = 0.5) and returned to 0.69 at M24 in the RTX-PEG-IFN/RBV group, whereas they were stable in the PEG-IFN/RBV group. RTX is safe in patients with severe HCV liver fibrosis and vasculitis. No beneficial effects of RTX were evidenced on liver fibrosis progression, but we found interesting correlations with the serum albumin level, FibroTest values and B-cell count. 相似文献

Summary
We have reviewed 47 drug rash with eosinophilia and systemic symptoms (DRESS) cases associated to strontium ranelate reported up to March 2011 to the Marketing Holder. The main signs were skin rash, fever, face oedema hypereosinophilia and liver involvement. For ten patients, persistence of DRESS symptoms was reported at the latest news obtained, and DRESS was identified as the direct cause of death in one case. The maximum incidence of DRESS associated with strontium ranelate was 1/24,112 [95 % CI (1/14,859; 1/42,194)] newly treated patients in France. Because DRESS is a severe drug reaction, the occurrence of a rash in a patient treated with strontium ranelate should lead to prompt and permanent treatment discontinuation.Introduction
This study aims to describe cases of DRESS reported to the Marketing Authorisation Holder worldwide for patients receiving strontium ranelate by practitioner or by regulatory authorities.Methods
Spontaneously reported hypersensitivity events from the strontium ranelate pharmacovigilance database since marketing authorisation (2004) to March 2011 were reviewed by an expert committee. Cases of DRESS were classified as established, probable, possible or no DRESS according to expert judgement. National incidences of DRESS were estimated in relation to the number of newly treated patients.Results
Up to March 2011, 325 cases of strontium ranelate-induced hypersensitivity events were assessed from which 47 DRESS cases were confirmed. Mean age was 68.7 years and besides skin rash, the main signs and symptoms were hypereosinophilia, liver involvement, fever and face oedema. Median time to skin reaction was 33.5 days after treatment start. Most patients (62 %) recovered at the time of reporting or were recovering. For ten patients, persistence of DRESS symptoms was reported at the latest news obtained. Relapses were observed in a single case. The mortality rate was 8.5 %. The maximum incidence of DRESS associated with strontium ranelate was 1/24,112 [95 % CI (1/14,859; 1/42,194)] newly treated patients in France.Conclusion
DRESS is a well-identified and characterised adverse reaction to strontium ranelate. This risk should be integrated in the risk-benefit balance evaluation of patient treatment, and the occurrence of a rash should lead to prompt and permanent treatment discontinuation with careful follow-up. 相似文献23.

Hepatitis C virus (HCV) infection has been demonstrated to result in several adverse hepatic outcomes and has been associated with a number of important extrahepatic manifestations. The scope of extrahepatic clinical possibilities includes systemic diseases such as vasculitis and lymphoproliferative disorders, cardiovascular disease, myalgia, arthritis, and sicca syndrome. These end‐organ effects of HCV may dominate the clinical course beyond the hepatic complications and significantly worsen the long‐term prognosis of infected patients. Until several years ago, the standard of care for the treatment of HCV infection had been interferon‐alpha‐based regimens, which not only had limited effectiveness in achieving a cure but were often poorly tolerated, especially in patients with kidney disease. In those HCV‐infected patients with significant systemic manifestations, the interferon‐based regimens were problematic given their association with a wide variety of toxicities. The development of highly effective direct‐acting antiviral agents to treat HCV infection presented an opportunity to improve the HCV care cascade with the eradication of HCV in most infected patients and by reducing the burden of both hepatic and extrahepatic complications. 相似文献

BACKGROUND/AIMS: To analyze the barriers to HCV treatment in HIV-HCV co-infected patients and their evolution between 2004 and 2006. METHODS: Three hundred and eighty HIV-HCV co-infected patients were prospectively included in surveys from November 22 to 29, 2004 (2004 survey), and 416 from April 3 to 10, 2006 (2006 survey). RESULTS: Patients in 2006 compared to those in 2004 had negative HCV RNA more often (24% vs. 12%). The rate of liver biopsy was similar (56% vs. 54%) while 24% had had a non-invasive liver damage assessment. The rate of previous treatment for HCV infection was higher (48% vs. 26%). The main reasons for HCV non-treatment have changed: HCV treatment deemed questionable (44% vs. 53%), lack of liver biopsy (18% vs. 33%), physicians' conviction of poor patient compliance (20% vs. 30%). In both surveys, HCV treated patients were more often of European origin, had better control of HIV infection, and had a liver damage assessment more often. CONCLUSIONS: The care of HIV-HCV co-infected patients has changed significantly in "real life". These results underline the importance of continuing efforts to educate physicians and patients in order to increase the access of co-infected patients to HCV treatment. 相似文献

Trak-C (Ortho-Clinical Diagnostics) is an enzyme-linked immunosorbent assay-based method capable of quantifying hepatitis C virus (HCV) core antigen (CA) in serum and could be an alternative to molecular detection and quantification of HCV RNA. We have evaluated the Trak-C assay in comparison with an HCV RNA quantitative assay (Versant HCV v3.0; Bayer Diagnostics) in the follow-up of 348 treated, human immunodeficiency virus (HIV)/HCV-coinfected patients included in the ANRS HC02 RIBAVIC trial. ANRS HC02 RIBAVIC is a therapeutic, multicenter, randomized protocol comparing the efficacy of alpha interferon 2b (IFN-alpha2b) (3 million units three times a week)-ribavirin (800 mg/day) to that of pegylated IFN-alpha2b (1.5 mug/kg of body weight/week)-ribavirin (800 mg/day) during 48 weeks of treatment of HIV/HCV-coinfected patients na?ve to HCV treatment. Patients were assessed for virological analysis at day 0 and weeks 4, 12, 24, 48, and 72. Correlation of HCV RNA and HCV CA at the initiation of treatment was excellent (r = 0.92). HCV RNA and CA kinetics were similar during follow-up of HCV treatment from day 0 to week 72 whatever the group of response and genotype. The positive and negative predictive values of response to the treatment at week 4 were 59 and 94%, respectively, for HCV RNA load reduction of >2 log and 54 and 94%, respectively, for HCV CA below the threshold value (4.18 log(10) pg/ml . 10(4)). Trak-C, a new assay able to quantify CA in HIV/HCV-coinfected patients, correlates well with quantitative HCV RNA assays and is cheaper and easier to perform than molecular technology. HCV CA could be a valuable alternative test for therapeutic follow-up of coinfected patients treated with IFN plus ribavirin in developing countries. 相似文献
