High baseline bilirubin and low albumin predict liver decompensation and serious adverse events in HCV-infected patients treated with sofosbuvir-containing regimens.

To conduct surveillance and determine the safety profile of new hepatitis C virus treatments in real-world clinical practice. Hepatic decompensation and other serious adverse events were investigated in an observational cohort study of 511 patients treated with regimens containing sofosbuvir, December 2013-June 2014. Among 499 previously stable patients (no history of hepatic decompensation during the previous 12 months), a nested case-control study was performed to identify predictors of decompensation/serious adverse event. Cases and controls were matched 1:5 based on treatment regimen and duration. Matched conditional logistic regression was used for analysis. Providers scored the likelihood that events were treatment-related (scale = 0-4). The cumulative incidence of decompensation/events was 6.4% for the total cohort. Among 499 previously stable patients, the incidence of decompensation/events was 4.5%; the mortality rate was 0.6%. Sixteen of the 499 experienced one or more serious complications considered to be at least potentially treatment-related, and the sustained virological response rate was 7/16 (44%). Two cases, both on sofosbuvir/simeprevir (without interferon or ribavirin), had complications consistent with autoimmune events (score 3, 'likely treatment-related'), and one experienced a flare of autoimmune hepatitis. Compared to controls, cases had higher baseline median model for end-stage liver disease scores (14 vs 8, P < 0.01). Decompensation/events was independently associated with lower baseline albumin (OR = 0.12/g/dL, P = 0.01) and higher total bilirubin (OR = 4.31/mg/dL, P = 0.01). Reduced hepatic function at baseline increased the risk of liver decompensation/events.

Clinical characteristics of human immunodeficiency virus patients being referred for liver transplant evaluation: a descriptive cohort study.

BACKGROUND: Liver transplantation (LT) is a treatment option for select human immunodeficiency virus (HIV)-infected patients with advanced liver disease. The aim of this study was to describe LT evaluation outcomes in HIV-infected patients. METHODS: All HIV-infected patients referred for their first LT evaluation at the Mount Sinai Medical Center were included in this retrospective, descriptive cohort study. Multivariable logistic regression was used to identify factors independently associated with listing. RESULTS: Between February 2000 and April 2012, 366 patients were evaluated for LT, with 66 (18.0%) listed for LT and 300 (82.0%) not listed. Fifty-one patients (13.9%) died before completing evaluation and 85 (23.2%) were too early for listing. Reasons patients were declined for listing were psychosocial (15.8%), HIV-related (10.4%), loss to follow-up (9.6%), surgical/medical (6.0%), liver-related (4.4%), patient choice (3.4%), and financial (1.6%). Listed patients were more likely to have hepatocellular carcinoma (HCC) (43.1% vs. 17.1%; P < 0.0001) and less likely to have hepatitis B (6.2% vs. 15.7%; P = 0.04) or a psychiatric history (19.7% vs. 35.2%; P = 0.02) than those not listed. In multivariable analysis, HCC (odds ratio [OR] 5.79; 95% confidence interval [95% CI]: 2.97-11.28), model for end-stage liver disease (MELD) score at referral (OR 1.06; 95% CI 1.01-1.11), and hepatitis B (OR 0.26; 95% CI 0.08-0.79) were associated with listing. CONCLUSION: MELD score and HCC were positive predictors of listing in HIV-infected patients referred for LT evaluation and, therefore, timely referrals are vital in these patients. As MELD is a predictor for death while undergoing evaluation, rapid evaluation should be performed in HIV-infected patients with a higher MELD score.

Effect of fibrosis on adverse events in patients with hepatitis C treated with telaprevir.

BACKGROUND: Data about adverse events are needed to optimise telaprevir-based therapy in a broad spectrum of patients. AIM: To investigate adverse events of telaprevir-based therapy in patients with and without advanced fibrosis or cirrhosis in a real-world setting. METHODS: Data on 174 hepatitis C-infected patients initiating telaprevir-based therapy at Mount Sinai and Montefiore medical centres were collected. Biopsy data and FIB-4 scores identified patients with advanced fibrosis. Multivariable fully adjusted models were built to assess the effect of advanced fibrosis on specific adverse events and discontinuation of treatment due to an adverse event. RESULTS: Patients with (n = 71) and without (n = 103) advanced fibrosis were similar in BMI, ribavirin exposure, gender, prior treatment history, haemoglobin and creatinine, but differed in race. Overall, 47% of patients completed treatment and 40% of patients achieved SVR. Treated patients with and without advanced fibrosis or cirrhosis had similar rates of adverse events; advanced fibrosis, however, was independently associated with ano-rectal discomfort (P = 0.03). Three patients decompensated and had advanced fibrosis. The discontinuation of all treatment medications due to an adverse event was significantly associated with older age (P = 0.01), female gender (P = 0.01) and lower platelets (P = 0.03). CONCLUSIONS: Adverse events were common, but were not significantly related to the presence of advanced fibrosis or cirrhosis. More critical monitoring in older and female patients with low platelets throughout treatment may reduce adverse event-related discontinuations.

Virological response rates for telaprevir-based hepatitis C triple therapy in patients with and without HIV coinfection.

OBJECTIVES: Pegylated-interferon/ribavirin dual therapy for hepatitis C virus (HCV) infection has a lower sustained virological response (SVR) rate in HIV/HCV-coinfected patients than in HCV monoinfected patients, but little is known about the relative effectiveness of teleprevir-based triple therapy in the two groups. METHODS: Data on 33 coinfected and 116 monoinfected patients were analysed on an intention-to-treat basis. SVR12 was defined as undetectable HCV RNA at week 12 post-end-of-treatment, severe anaemia as haemoglobin ≤ 89 g/L or a drop of ≥ 45 g/L, and advanced fibrosis/cirrhosis as Fib-4 ≥ 3.25. All coinfected patients had well controlled HIV infection. RESULTS: The groups were similar in age, gender, percentage with Fib-4 ≥ 3.25 and HCV viral load, but differed in previous treatment response, with more coinfected patients being nonresponders or treatment-intolerant (75.8% vs. 50.0% for monoinfected patients; P < 0.01). During treatment, the percentages of patients with undetectable HCV RNA were similar, but, surprisingly, this percentage tended to be higher in coinfected patients. SVR12 rates were 60.6% in coinfected patients vs. 42.2% in monoinfected patients (P = 0.06). In multivariable analysis, SVR12 was associated with HIV infection [odds ratio (OR) 3.55; P < 0.01], African American race (OR 0.37; P = 0.03) and previous treatment response (OR 0.46; P = 0.03). Rates of severe anaemia (45.5 vs. 58.6% in coinfected and monoinfected patients, respectively; P = 0.18) were similar in the two groups, but rash (15.2 vs. 34.5%, respectively; P = 0.03) and rectal symptoms (12.1 vs. 43.1%, respectively; P < 0.01) were less common in coinfected patients. CONCLUSIONS: Virological responses of coinfected and monoinfected patients did not differ significantly, but tended to be higher in coinfected patients, who had a 60.6% SVR12 rate. Telaprevir-based triple therapy is a promising option for coinfected patients with well-controlled HIV infection.
