Diabetes Mellitus Increases the Risk of Hepatocellular Carcinoma After Direct-Acting Antiviral Therapy: Systematic Review and Meta-Analysis

ABSTRACT: Background: Hepatitis C virus (HCV)-infected patients treated with direct-acting antivirals (DAAs) are still at risk of developing hepatocellular carcinoma (HCC) after sustained virologic response (SVR). This study aimed to investigate the role of diabetes mellitus (DM) as a potential predictive risk factor in developing de novo HCC in HCV-infected patients after DAA treatment. Methods: This study was registered on PROSPERO under registration number CRD42021230457. We performed a systematic search in four medical databases from inception through November 3rd, 2020. Studies were eligible if they reported on HCV-infected patients treated with DAAs and compared the frequency of de novo HCC in patients with and without DM. We calculated pooled odds ratios, unadjusted (UHR), and adjusted hazard ratios (AHR) with 95% confidence intervals (CIs) in meta-analysis. Results: We included 30 articles in our systematic review and meta-analysis. DM proved to be a significant risk factor of HCC in DAA-treated HCV patients in unadjusted (UHR = 1.44, CI: 1.15–1.79) and adjusted analyses (AHR = 1.31, CI: 1.06–1.62). In the group of patients achieving SVR after DAA therapy, DM increased the risk of HCC in unadjusted (UHR = 1.3, CI: 1.09–1.51) analysis; however, in adjusted results, the risk was non-significant (AHR = 1.07, CI: 0.89–1.28). In patients with advanced liver fibrosis, DM was a risk factor for HCC in adjusted (AHR = 1.36, CI: 1.03–1.8), but not in unadjusted analysis (UHR = 1.11, CI: 0.8–1.42). Conclusions: DM is an independent risk factor of de novo HCC after DAA treatment in HCV-infected patients.

Project description:Background & aimsDirect-acting antivirals (DAAs) are effective against hepatitis C virus and sustained virologic response is associated with reduced incidence of hepatocellular carcinoma (HCC). However, there is controversy over the use of DAAs in patients with active or treated HCC and uncertainty about optimal management of these patients. We aimed to characterize attitudes and practice patterns of hepatology practitioners in the United States regarding the use of DAAs in patients with HCC.MethodsWe conducted a survey of hepatology providers at 47 tertiary care centers in 25 states. Surveys were sent to 476 providers and we received 279 responses (58.6%).ResultsProvider beliefs about risk of HCC recurrence after DAA therapy varied: 48% responded that DAAs reduce risk, 36% responded that DAAs do not change risk, and 16% responded that DAAs increase risk of HCC recurrence. However, most providers believed DAAs to be beneficial to and reduce mortality of patients with complete response to HCC treatment. Accordingly, nearly all providers (94.9%) reported recommending DAA therapy to patients with early-stage HCC who received curative treatment. However, fewer providers recommended DAA therapy for patients with intermediate (72.9%) or advanced (57.5%) HCC undergoing palliative therapies. Timing of DAA initiation varied among providers based on HCC treatment modality: 49.1% of providers reported they would initiate DAA therapy within 3 months of surgical resection whereas 45.9% and 5.0% would delay DAA initiation for 3-12 months and >1 year post-surgery, respectively. For patients undergoing transarterial chemoembolization (TACE), 42.0% of providers would provide DAAs within 3 months of the procedure, 46.7% would delay DAAs until 3-12 months afterward, and 11.3% would delay DAAs more than 1 year after TACE.ConclusionsBased on a survey sent to hepatology providers, there is variation in provider attitudes and practice patterns regarding use and timing of DAAs for patients with HCC. Further studies are needed to characterize the risks and benefits of DAA therapy in this patient population.

Project description:Background & aimsThere is controversy over the effects of direct-acting antiviral (DAA) therapies for hepatitis C virus (HCV) infection on hepatocellular carcinoma (HCC) recurrence and tumor aggressiveness. We compared HCC recurrence patterns between DAA-treated and untreated HCV-infected patients who had achieved a complete response to HCC treatment in a North American cohort.MethodsWe conducted a retrospective cohort study of patients with HCV-related HCC with a complete response to resection, local ablation, transarterial chemo- or radioembolization, or radiation therapy from January 2013 through December 2017 at 31 health systems throughout the United States and Canada. Cox regression was used to examine the association between DAA therapy and time to recurrence after a complete response, with DAA therapy analyzed as a time-varying exposure. We also estimated the association between DAA therapy and risk of early HCC recurrence (defined as 365 days after complete response).ResultsOf 793 patients with HCV-associated HCC, 304 (38.3%) received DAA therapy and 489 (61.7%) were untreated. HCC recurred in 128 DAA-treated patients (42.1%; early recurrence in 52 patients) and 288 untreated patients (58.9%; early recurrence in 227 patients). DAA therapy was not associated with HCC recurrence (hazard ratio 0.90, 95% confidence interval 0.70-1.16) or early HCC recurrence (hazard ratio 0.96, 95% confidence interval 0.70-1.34) after we adjusted for study site, age, sex, Child-Pugh score, α-fetoprotein level, tumor burden, and HCC treatment modality. In DAA-treated and untreated patients, most recurrences were within the Milan criteria (74.2% vs 78.8%; P = .23). A larger proportion of DAA-treated than untreated patients received potentially curative HCC therapy for recurrent HCC (32.0% vs 24.6%) and achieved a complete or partial response (45.3% vs 41.0%) but this did not achieve statistical significance.ConclusionIn a large cohort of North American patients with complete response to HCC treatment, DAA therapy was not associated with increased overall or early HCC recurrence. HCC recurrence patterns, including treatment response, were similar in DAA-treated and untreated patients.

Project description:IntroductionType 2 diabetes mellitus (DM) and diabetic kidney disease are increasing. Hepatitis C infection (HCV) occurs in 1% of the world population and can induce several kidney diseases. DM prevalence is increased in individuals with HCV; however, kidney diseases in those with both DM and HCV have not been assessed. Direct-acting antiviral agents (DAAs) became available for HCV treatment in 2014; it is unknown if DAAs altered the spectrum of kidney disease in patients with DM and HCV.MethodsCase review identifying patients with kidney biopsy and clinical history of DM and HCV between 2009-2013 (pre-DAA) and 2016-2020 (post-DAA), excluding kidney transplant, hepatitis B, HIV, and inadequate biopsy, identified 245 biopsies. Biopsies were evaluated for diabetic glomerulosclerosis (DGS) class, global and focal segmental glomerulosclerosis (FSGS), other glomerular diseases, interstitial fibrosis/tubular atrophy (IFTA), interstitial nephritis, acute tubular injury and degree of arterial and arteriolar sclerosis. Kidney disease differences in pre-DAA versus post-DAA eras and in mild versus severe DGS were assessed by χ2 and Fisher's exact tests.ResultsThe most common non-DGS lesions were non-collapsing FSGS (41%), HCV-related IgM dominant immune complex glomerulonephritis (IgM-ICGN, 18%), IgA nephropathy (9%), and membranoproliferative glomerulonephritis (MPGN, 7%). Collapsing FSGS was more common pre-DAA versus post-DAA (8% vs. 1%, p = 0.03). Biopsies from patients with HCV and DM were reduced in post-DAA (0.7%) versus pre-DAA (1.3%) (p < 0.0001). Post-DAA there were less MPGN (2% vs. 10%, p = 0.02) and more advanced DGS (85% vs. 61%, p = 0.0002), non-collapsing FSGS (57% vs. 31%, p < 0.0001), IFTA (2.0 vs. 1.6, p = 0.0002), and vascular sclerosis (2.1 vs. 1.6, p < 0.0001).ConclusionPost-DAA there were reduced biopsies and MPGN, with more severe DGS class, non-collapsing FSGS, IFTA, and chronic vascular changes. This suggests a modulating effect of DAAs on HCV-related kidney pathology with DM and chronic changes driving indications for kidney biopsy.
