RESUMO

OBJECTIVE: Direct-acting antivirals for the treatment of hepatitis C virus (HCV) represented a paradigm shift. In 2017, sofosbuvir/velpatasvir (SOF/VEL-Epclusa®) was approved, which showed a high cure rate in all patient, contributing to HCV elimination. The analysis aimed to quantify the clinical and economic value of SOF/VEL in HCV chronic patients since its approval in Spain. METHODS: An economic evaluation was elaborated adapting a Markov model that simulated the lifetime disease progression in of all HCV chronic patients treated with SOF/VEL (30,488 patients) since its launch (5-years), compared to previous therapies. Patients entered the model and were distributed between the fibrosis states (F0-to-F4) in treated and untreated. All patients (100%) were treated with SOF/VEL regardless of their fibrosis, and 49% with previous therapies in ≥F2. The average sustained viral response (SVR) rates 98.9% SOF/VEL versus 61.0% previous therapies. All parameters for the analysis were obtained from real-life data and literature. Only direct healthcare costs associated with disease management were included. The SOF/VEL value was measured as the number of hepatic complications avoided and their associated cost, and hepatic mortality compared to previous therapies. National Health System perspective and a 3% discount rate was applied. RESULTS: SOF/VEL decreased the number of liver complications, avoiding 92% decompensated cirrhosis, 80% hepatocellular carcinomas, and 87% liver transplants, as well as 85% liver-related mortality. Their cost associated was reduced, amounting to savings of 197M€. CONCLUSION: SOF/VEL adds relevant value to the HCV treatment, reducing the clinical and economic disease burden and contributing to HCV elimination in Spain.

RESUMO

BACKGROUND & AIMS: Hepatitis B infection is the most frequent cause of chronic hepatitis and liver cancer worldwide. Active searching for individuals with chronic hepatitis B has been proposed as a strategy to achieve the elimination of this virus. The primary aim of this study was to link to specialists HBsAg-positive individuals detected in a laboratory database and to characterize individuals who were not linked to care. METHODS: We performed a retrospective-prospective evaluation of all HBsAg-positive serum samples identified in the central laboratory of the Northern Barcelona area between January 2018 and June 2022. After reviewing the patients' clinical charts, all those not linked to care were given an appointment with a specialist. RESULTS: Medical records of 2765 different HBsAg-positive serum samples were reviewed and 2590 individuals were identified: 844 (32.6%) were not linked to a specialist, 653 were candidates for linkage, and 344 attended the specialist visit. The two main reasons why they were not under specialist care were administrative issues, such as living in another region (12.1%) and lacking contact details (4.1%), and low life expectancy (2.8%). Individuals who did not attend their scheduled visit were mainly young [38.1 ± 12.9 vs. 44.0 ± 14.0 (p < .001)], non-White European [75.3% vs. 58.1% (p < .001)] and men [70.7% vs. 56.4% (p < .001)]. CONCLUSIONS: One in every three HBsAg-positive individuals in our setting was not currently under specialist care. Of particular note, half of them had never attended a specialist consultation, an essential step for evaluating the disease and starting therapy in some countries.

RESUMO

Chronic hepatitis D (CHD) is a severe form of viral hepatitis that leads to liver cirrhosis and hepatocellular carcinoma. CHD is underdiagnosed, and this study aimed to assess the impact of hepatitis D reflex testing in HBsAg-positive individuals in Spain over the next 8 years. Two scenarios were compared: the current situation (7.6% of HBsAg-positive patients tested for anti-HDV) and reflex testing for all positive samples. A decision tree model was designed to simulate the CHD care cascade. Implementing reflex testing would increase anti-HDV detection to 5498 cases and HDV-RNA to 3225 cases. Additionally, 2128 more patients would receive treatment, with 213 achieving undetectable HDV-RNA levels. The cost per anti-HDV case detected would be €132. In the median time of the analysis, liver complications (decompensated cirrhosis, HCC and liver-related deaths) would be reduced by 35%-38%, implying an estimated cost savings of 36 million euros associated with the management of such complications. By 2030, implementing anti-HDV reflex testing would reduce the clinical and economic burden of CHD by 35%-38%.

RESUMO

In 2016, the Hepatitis B and C Public Policy Association (HepBCPPA), gathered all the main stakeholders in the field of hepatitis C virus (HCV) to launch the now landmark HCV Elimination Manifesto, calling for the elimination of HCV in the EU by 2030. Since then, many European countries have made progress towards HCV elimination. Multiple programmes-from the municipality level to the EU level-were launched, resulting in an overall decrease in viremic HCV infections and liver-related mortality. However, as of 2021, most countries are not on track to reach the 2030 HCV elimination targets set by the WHO. Moreover, the COVID-19 pandemic has resulted in a decrease in HCV diagnoses and fewer direct-acting antiviral treatment initiations in 2020. Diagnostic and therapeutic tools to easily diagnose and treat chronic HCV infection are now well established. Treating all patients with chronic HCV infection is more cost-saving than treating and caring for patients with liver-related complications, decompensated cirrhosis or hepatocellular carcinoma. It is more important than ever to reinforce and scale-up action towards HCV elimination. Yet, efforts urgently need the dedicated commitment of policymakers at all governmental and policy levels. Therefore, the third EU Policy Summit, held in March 2021, featured EU parliamentarians and other key decision makers to promote dialogue and take strides towards securing wider EU commitment to advance and achieve HCV elimination by 2030. We have summarized the key action points and reported the 'Call-to-Action' statement supported by all the major relevant European associations in the field.

RESUMO

BACKGROUND: The treatment of chronic hepatitis C virus (HCV) with direct-acting antivirals has undergone a spectacular revolution and added significant value to healthcare systems and patients. The aim of the study was to evaluate the efficiency and value of Sofosbuvir (SOF)-based regimens for a target population of 85,959 chronic HCV patients treated in Spain during 2015-2019, compared to previous therapeutic strategies (peginterferon/ and ribavirin in double/triple therapy with telaprevir or boceprevir). METHODS: A previously developed lifetime Markov model was adapted to simulate the disease HCV evolution. In SOF-based regimens, all patients (100%) were treated regardless with sustained virological response (SVR) of 93-98%, obtained from real-world data. In previous therapeutic, only ≥F2 patients were treated according to clinical practice (38%) with an average SVR of 61% taken from published literature. The value was measured as clinical and economic impact in terms of avoided HCV-related mortality and liver complications; total costs and quality-adjusted life years (QALYs) applying an annual 3% discount rate. RESULTS: Compared to previous therapeutic, during lifetime, SOF-based regimens reduced decompensated cirrhosis by 89%, hepatocellular carcinoma by 77% and liver transplant by 84%, decreasing the cost associated to liver complications management in €770 million. SOF-based regimens also decreased liver-related mortality by 82%. Besides, SOF-based regimens gained 310,765/QALYs, saving €274 million (considering drugs, monitoring, and HCV management). CONCLUSION: For Spain, SOF-based regimens offer value for HCV patients in terms of lowering HCV-related liver disease burden and generating significant cost savings for the health system, contributing to the WHO goal.

RESUMO

Background and Aims: Hepatitis B virus (HBV) biomarkers have been used for a better categorization of patients, even though the lack of simple algorithms and the impact of genotypes limit their application. Our aim was to assess the usefulness of noninvasive markers for the identification of HBV inactive carriers (ICs) in a single-point evaluation and to design a predictive model for their identification. Methods: This retrospective-prospective study included 343 consecutive HBeAg-negative individuals. Clinical, analytical, and virological data were collected, and a liver biopsy was performed if needed. Subjects were classified at the end of follow-up as ICs, chronic hepatitis B and gray zone.A predictive model was constructed, and validated by 1000-bootstrap samples. Results: After 39 months of follow-up, 298 subjects were ICs, 36 were chronic hepatitis B CHB, and nine were gray zone. Eighty-nine (25.9%) individuals required a liver biopsy. Baseline HBV DNA hazard ratio (HR) 6.0, p<0.001), HBV core-related antigen (HBcrAg) (HR 6.5, p<0.001), and elastography (HR 4.6, p<0.001) were independently associated with the IC stage. The ACE score (HBV DNA, HBcrAg, elastography), obtained by bootstrapping, yielded an area under the receiver operating characteristics (AUROC) of 0.925 (95% CI: 0.880-0.970, p<0.001) for identification of ICs. The AUROC for genotype D was 0.95, 0.96 for A, 0.90 for E, and 0.88 for H/F. An ACE score of <1 had a positive predictive value of 99.5%, and a score ≤12 points had a diagnostic accuracy of 93.8%. Conclusions: Low baseline HBV DNA, HBcrAg, and liver stiffness were independently associated with the IC phase. A score including those variables identified ICs at a single-point evaluation, and might be applied to implement less intensive follow-up strategies.

RESUMO

BACKGROUND & AIMS: Achieving sustained virologic response (SVR) among patients with hepatitis C virus (HCV) leads to patient reported outcome (PRO) improvement. We aimed to assess the long-term post-SVR PRO trends in HCV patients with cirrhosis. METHODS: Patients with HCV and cirrhosis treated in clinical trials with direct acting antiviral agents (DAAs) who achieved SVR-12 were prospectively enrolled in a long-term registry (clinicaltrials.gov #NCT02292706). PROs were collected every 24 weeks using the Short Form-36v2 (SF-36), CLDQ-HCV, and WPAI-HCV. RESULTS: Pre-treatment baseline data were available for 854 cirrhotic patients who achieved SVR after DAAs. Of these, 730 had compensated (CC) and 124 had decompensated cirrhosis (DCC) before treatment- patients with DCC reported severe impairment in their PROs in comparison to CC patients (by mean -5% to -16% of a PRO range size; p < .05 for 16 out of 20 studied PROs]. After achieving SVR and registry enrollment, significant PRO improvements were noted from pre-treatment levels in 11/20 domains for those with DCC (+4% to +21%) and 19/20 PRO domains in patients with CC (+3% to +17%). Patients with baseline DCC had higher rates of hepatocellular carcinoma and mortality (P < .05). In patients with CC, the PRO gains persisted up to 168 weeks (3.5 years) of registry follow-up. In patients with DCC, the improvements lasted for at least 96 weeks but a declining trend after year 2. CONCLUSIONS: Patients with HCV cirrhosis experience severe PRO impairment at baseline with sustainable improvement after SVR. Though those with DCC experience improvement, there is a decline after 2 years.

RESUMO

Nucleoside analogues are the drugs most commonly used in the treatment of chronic hepatitis B. They act by inhibiting viral replication and have minimal impact on HBsAg loss. Nucleoside analogues are indicated in patients with chronic hepatitis, cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, and in those with extrahepatic manifestations. Real-world experience has been ongoing for more than 10 years, and the efficacy and safety results obtained are similar to those reported in clinical trials. Prolonged use is needed to maintain suppression of viral replication, prevent the development of liver cirrhosis and decompensated cirrhosis, and to decrease the risk of hepatocellular carcinoma.

RESUMO

BACKGROUND & AIMS: Recently, several risk scores for prediction of hepatocellular carcinoma (HCC) were developed in cohorts of treated Asian patients with chronic hepatitis B (CHB), but they have not been assessed in non-Asian patients. We evaluated the predictability and comparative utility of our PAGE-B and recent Asian HCC risk scores in nucleos(t)ide analogue (NA)-treated adult Caucasian patients with CHB, with or without well-documented compensated cirrhosis but not previous diagnosis of HCC. METHODS: We included 1,951 patients treated with entecavir/tenofovir and followed up for a median of 7.6 years. The c-statistic was used to estimate the predictability of PAGE-B, HCC-Rescue, CAMD, mPAGE-B, and AASL score for HCC development within 5 or 10 years. The low- and high-risk group cut-offs were used for estimation of negative (NPV) and positive predictive values (PPV), respectively. RESULTS: HCC developed in 103/1,951 (5.3%) patients during the first 5 years and in another 39/1,428 (2.7%) patients between years 5 and 10. The 3-, 5-, and 10-year cumulative HCC rates were 3.3%, 5.9%, and 9.6%, respectively. All scores offered good 5- and 10-year HCC prediction (c-statistic: 0.78-0.82). NPVs were always >99% (99.3-100%), whereas PPV ranged between 13% and 24%. CONCLUSIONS: In NA-treated Caucasian patients with CHB including compensated cirrhosis, HCC risk scores developed in NA-treated Asian patients offer good 5- and 10-year HCC predictability, similar to that of PAGE-B. PAGE-B and mPAGE-B scores are simpler in clinical practice, as they do not require an accurate diagnosis of cirrhosis, but the addition of albumin in mPAGE-B score does not seem to offer an advantage in patients with well compensated liver disease. LAY SUMMARY: Several risk scores for prediction of hepatocellular carcinoma (HCC) were recently developed in cohorts of treated Asian patients with chronic hepatitis B (CHB). In Caucasian patients with CHB treated with oral antivirals, newer Asian HCC risk scores offer good 5- and 10-year HCC predictability, similar to that of PAGE-B. For clinical practice, PAGE-B and mPAGE-B scores are simpler, as they do not require an accurate diagnosis of cirrhosis.

RESUMO

Nucleos(t)ide analogues with high barrier to resistance are regarded as the principal therapeutic option for chronic hepatitis B (CHB). Treatment with entecavir (ETV), tenofovir disoproxil (TDF) and the later released tenofovir alafenamide (TAF) is highly effective at controlling hepatitis B virus (HBV) infection and, in the vast majority of patients, is well tolerated. No significant differences in viral suppression have been described among the different regimens, although an earlier achievement in biochemical response has been suggested first under TDF and recently under TAF. High barrier to resistance NAs rarely achieve hepatitis B surface antigen sero-clearance, and therefore should be maintained life-long in most cases. This has increased concerns about treatment-related toxicity, especially in patients under TDF with additional risk factors for kidney and bone impairment. TAF has shown a better bone and kidney safety profile than TDF, although it is not yet available worldwide due to its higher cost. Emergence of adverse events should be monitored since treatment-switch to ETV/TAF seems to be effective and safe in HBV mono-infected subjects. Finally, although an effective antiviral treatment leads to a clear improvement in clinical outcome of CHB patients; the risk of developing hepatocellular carcinoma (HCC) is not completely avoided with viral suppression. Whether tenofovir-based regimens provide any additional benefit over ETV in HCC prevention remains unclear and requires further investigation.

RESUMO

The publication of the Screening Guidelines for Hepatitis C Virus Infection represents a significant milestone in the path towards eliminating this infectious condition. As early as 2015, the National Health System Plan for Tackling Hepatits C (Plan estratégico para el abordaje de la hepatitis C - PEAHC) pointed out the need to define a screening policy. The Health Ministry has managed to bring together all the actors involved, and to create a technical document that represents a benchmark in the definition of the actions needed to identify and bring treatment closer to a significant number of patients diagnosed with hepatitis C who remain untreated.

RESUMO

Hepatitis B virus (HBV) infection remains a global public health problem. HBV vaccination is the most effective tool to reduce the incidence of HBV disease. Despite there has not been new clinical developments for the treatment of chronic hepatitis B in the last few years, changing epidemiology and current insights on natural history, diagnostic tools and therapy indications make necessary an update of the former version of the consensus document of the Spanish Association for Study of the Liver on the treatment of hepatitis B infection published in 2012. The current document updates the management of chronic hepatitis B. The treatment of choice is the long-term administration of a nucleos(t)ide analogue with high barrier to resistance (entecavir, tenofovir or tenofovir alafenamide). Pegylated interferon may be an option in patients with non-advanced liver disease, but its applicability is limited due to the low efficacy and poor tolerability. All patients must be monitored for the risk of progression to advanced liver disease and development of hepatocellular carcinoma.

RESUMO

BACKGROUND: Since it is currently not possible to eradicate hepatitis B virus (HBV) infection with existing treatments, research continues to uncover new therapeutic strategies. HBV core protein, encoded by the HBV core gene (HBC), intervenes in both structural and functional processes, and is a key protein in the HBV life cycle. For this reason, both the protein and the gene could be valuable targets for new therapeutic and diagnostic strategies. Moreover, alterations in the protein sequence could serve as potential markers of disease progression. AIM: To detect, by next-generation sequencing, HBC hyper-conserved regions that could potentially be prognostic factors and targets for new therapies. METHODS: Thirty-eight of 45 patients with chronic HBV initially selected were included and grouped according to liver disease stage [chronic hepatitis B infection without liver damage (CHB, n = 16), liver cirrhosis (LC, n = 5), and hepatocellular carcinoma (HCC, n = 17)]. HBV DNA was extracted from patients' plasma. A region between nucleotide (nt) 1863 and 2483, which includes HBC, was amplified and analyzed by next-generation sequencing (Illumina MiSeq platform). Sequences were genotyped by distance-based discriminant analysis. General and intergroup nt and amino acid (aa) conservation was determined by sliding window analysis. The presence of nt insertion and deletions and/or aa substitutions in the different groups was determined by aligning the sequences with genotype-specific consensus sequences. RESULTS: Three nt (nt 1900-1929, 2249-2284, 2364-2398) and 2 aa (aa 117-120, 159-167) hyper-conserved regions were shared by all the clinical groups. All groups showed a similar pattern of conservation, except for five nt regions (nt 1946-1992, 2060-2095, 2145-2175, 2230-2250, 2270-2293) and one aa region (aa 140-160), where CHB and LC, respectively, were less conserved (P < 0.05). Some group-specific conserved regions were also observed at both nt (2306-2334 in CHB and 1935-1976 and 2402-2435 in LC) and aa (between aa 98-103 in CHB and 28-30 and 51-54 in LC) levels. No differences in insertion and deletions frequencies were observed. An aa substitution (P79Q) was observed in the HCC group with a median (interquartile range) frequency of 15.82 (0-78.88) vs 0 (0-0) in the other groups (P < 0.05 vs CHB group). CONCLUSION: The differentially conserved HBC and HBV core protein regions and the P79Q substitution could be involved in disease progression. The hyper-conserved regions detected could be targets for future therapeutic and diagnostic strategies.

RESUMO

BACKGROUND & AIMS: A recent study in Asian patients with chronic hepatitis B (CHB) reported that the incidence of hepatocellular carcinoma (HCC) was lower in patients treated with tenofovir disoproxil fumarate (TDF) than entecavir (ETV), but this finding remains controversial. We aimed to identify any differences in HCC incidence, or other patient outcomes, between patients receiving TDF or ETV in the well monitored, multicenter European PAGE-B cohort. METHODS: We included 1,935 Caucasians with CHB, with or without compensated cirrhosis, treated with ETV (n = 772) or TDF (n = 1,163) monotherapy. Mean follow-up was 7.1 ± 3.0 years from ETV/TDF onset. RESULTS: The 5-year cumulative HCC incidence was 5.4% in ETV- and 6.0% in TDF-treated patients (log-rank, p = 0.321), with no significant difference in any patient subgroup (with or without cirrhosis, naïve or experienced to oral antiviral(s) [total, with or without cirrhosis]). In multivariable Cox regression analyses, the hazard of HCC was similar between ETV- and TDF-treated patients after adjustment for several HCC risk factors. ETV- and TDF-treated patients had similar rates of on-therapy biochemical and virological remission, HBsAg loss, liver transplantation and/or death. Elastographic reversion of cirrhosis at year 5 (liver stiffness <12 kPa) was observed in 245/347 (70.6%) patients with pretreatment cirrhosis, being more frequent in TDF- than ETV- treated patients (73.8% vs. 61.5%, p = 0.038). CONCLUSION: In Caucasian patients with CHB, with or without cirrhosis, long-term ETV or TDF monotherapy is associated with similar HCC risk, rates of biochemical/virological remission, HBsAg loss and liver transplantation or death, but elastographic reversion of cirrhosis at year 5 was more frequent with TDF. LAY SUMMARY: In a large cohort of Caucasians with chronic hepatitis B treated with entecavir (ETV) or tenofovir disoproxil fumarate (TDF) monotherapy, cumulative rates of hepatocellular carcinoma did not differ (up to 12 years). Nor did rates of biochemical/virological remission, HBsAg loss and liver transplantation or death. However, elastographic reversion of cirrhosis at year 5 was more frequent in TDF- than ETV-treated patients with pretreatment cirrhosis.

RESUMO

BACKGROUND & AIMS: Check point inhibitors (CPI) have improved survival of oncology patients but adverse effects that mimic autoimmune disorders have been reported. Our aim was describe the characteristics of immune-related hepatitis (irH) and prognosis, and compared them to those of patients with autoimmune hepatitis (AIH). METHODS: This is a retrospective study including all grade ≥ 3 (severe) irH diagnosed among 414 patients treated with CPI from 2016 to 2018. RESULTS: Twenty-eight cases of severe irH were recorded: 10 on anti-CTLA-4 ± anti-PD1/PD-L1 and 18 on anti-PD1/PD-L1. Half were female, age 63 years, median time on CPI three cycles. Four (14.3%) presented acute liver injury or failure and one (3.6%) died as consequence. 94% presented normal immunoglobulin G (IgG). Six (21.4%) patients were retreated with CPI and none presented relapse or new immune-related adverse events after a median cycles of 11 (range 6-36). Subjects with irH were older and had lower IgG values than a cohort of AIH (N = 38). Presentation tended to be more severe in AIH. Twenty-five percent of irH and 84% AIH presented ANAs ≥ 1:80 (P = .001). In irH Initial dose of corticosteroids was higher (60 vs 30 mg, P < .001) but duration shorter (2.3 vs 7 months, P < .001) and frequently in monotherapy (41.7% vs 91.3%, P < .001). CONCLUSIONS: Immune-related hepatitis can lead to acute liver failure, with absence of increased values of IgG and ANAs. In contrast to autoimmune hepatitis, initial corticosteroids dose were higher, duration shorter with few requiring additional immunosuppression.

RESUMO

Management of chronic hepatitis B (CHB) is still considered a challenge in clinical practice. Patients must be carefully evaluated before starting therapy. This includes virology and laboratory assessments, an estimation of fibrosis by invasive and/or noninvasive methods, and an estimation of the risk of hepatocellular carcinoma (HCC). Nucleos(t)ide analogues (NAs) with a high barrier to resistance (tenofovir disoproxil fumarate [TDF], entecavir [ETV] and tenofovir alafenamide [TAF]) are the most frequently used treatments because of their good long-term efficacy and tolerability. None of these options has been shown to be more effective than the other, but certain factors should be considered when selecting the best therapy for specific populations. Most patients achieve a virological and biochemical response to these agents, with a low rate of emerging resistance during long-term treatment. However, the rate of hepatitis B surface antigen (HBsAg) loss is low and in most cases NAs therapy is lifelong. Safety concerns for long-term NA use have become a priority in the management of CHB, in particular, the risk of impaired kidney function and bone marrow density loss described with TDF regimens. The risk of HCC is not completely eliminated by NAs. Thus, patients at higher risk should be identified and provided with appropriate surveillance.

RESUMO

Treatment of haematological disorders in patients with chronic hepatitis B or resolved infection (anti-HBc-positive) is associated with a risk of hepatitis B reactivation. Moreover, patients with chronic hepatitis C have a higher risk of haematological malignancies than general population. An electronic alert system was developed to promote screening of hepatitis B (HBV) and C (HCV) in patients starting haematological therapies. The system included screening and linkage to care and a request for testing in those without data. From March, 2017 to March, 2018 data from 420 consecutive patients with haematological diseases were included. At first prescription before the alerts, the HCV and HBV screening rate was 60.5%. Following the alerts, an additional 115 were screened, increasing the overall screening rate to 87.9%. Anti-HBc alone was detected in 57, anti-HCV in 13, and HBsAg in 2 patients. Overall, 68% of patients with any viral hepatitis markers were previously not know, and the impact was particularly important for anti-HBc detection (47/57 unknown). Nucleoside analogues were prescribed in 28 (49.1%) anti-HBc-positive and the 2 HBsAg-positive patients. Prospective follow-up with HBV DNA and HBsAg testing showed no cases of HBV reactivation. An estimated 1.2 HBV reactivations were avoided as consequence of the alert system. In summary, an electronic alert system increased viral hepatitis screening in patients receiving haematological treatment and led to improvements in the management of these patients, including avoided HBV reactivation.

RESUMO

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) may develop in patients with chronic hepatitis (CHB) even after 5 years of oral therapy and cannot be easily predicted. We assessed predictors of HCC development and the need for HCC surveillance in this setting. METHODS: Of 1,951 adult Caucasians with CHB included in the PAGE-B cohort, 1,427 (73%) had completed >5 years of follow-up under therapy without developing HCC by year 5. Median follow-up was 8.4 years from treatment onset. Points-based risk scores were developed to predict HCC risk after year 5. RESULTS: In years 5-12, HCC was diagnosed in 33/1,427 (2.3%) patients with cumulative incidences of 2.4%, 3.2% and 3.8% at 8, 10 and 12 years, respectively. Older age or age >50 years, baseline cirrhosis and liver stiffness (LSM) ≥12 kPa at year 5 were independently associated with increased HCC risk. The HCC incidence was lower in non-cirrhotics than cirrhotics at baseline with year-5 LSM <12; among cirrhotics at baseline, it was lower in those with year-5 LSM <12 than ≥12 kPa. CAGE-B score was based on age at year 5 and baseline cirrhosis in relation to LSM at year 5 and SAGE-B score was based only on age and LSM at year 5 (c-index = 0.809-0.814, 0.805-0.806 after bootstrap validation). Both scores offered 100% negative predictive values for HCC development in their low risk groups. CONCLUSIONS: In Caucasians with CHB, the HCC risk after the first 5 years of antiviral therapy depends on age, baseline cirrhosis status and LSM at year 5. CAGE-B and particularly SAGE-B represent simple and reliable risk scores for HCC prediction and surveillance beyond year 5 of therapy. LAY SUMMARY: In Caucasians with chronic hepatitis B, the risk of hepatocellular carcinoma after the first 5 years of entecavir or tenofovir therapy depends on age, baseline cirrhosis status and liver stiffness at year 5, which can provide simple and reliable risk scores for hepatocellular carcinoma prediction and surveillance beyond year 5. In patients with cirrhosis at baseline, liver stiffness <12 kPa at year 5 is associated with lower HCC risk, but surveillance may be still required.

RESUMO

BACKGROUND: Chronic hepatitis delta is a severe liver disease with rapid progression to cirrhosis. The impact of hepatitis delta virus (HDV)-RNA on disease progression and interferon treatment in a real-world cohort has been barely explored. AIM: To assess the development of clinical events in a cohort of chronic hepatitis delta patients according to the presence or absence of HDV-RNA METHODS: Multicentre study at four academic hospitals in Spain included anti-HDV-positive patients with compensated liver disease with a follow-up ≥12 months. RESULTS: Among 2888 HBsAg-positive subjects, 151 (5.2%) tested positive for anti-HDV, and 118 were included (58% men; median age, 49 years; 73% detectable HDV-RNA and 30% cirrhosis, most often in subjects with HDV-RNA). After a median follow-up of 8 years, subjects with initially detectable HDV-RNA were more prone to developing cirrhosis (31% vs 0%, P = .002) and/or liver decompensation (28% vs 3%, P = .019). Mortality rate was 0.44 per 1000 person-months. The probability of a clinical event was 6%, 25%, and 80% according to initial baseline-event-anticipation score. HDV-RNA became undetectable in 21 (24%) subjects either due to interferon or spontaneously (48% vs 52%, P = .29). Liver decompensation was reduced in interferon-treated patients (13% vs 38%, P = .026). CONCLUSIONS: Subjects with persistently positive HDV-RNA had a worse prognosis in terms of clinical events. Baseline-event-anticipation score is useful in predicting the risk of developing liver decompensation and hepatocellular carcinoma. Interferon was beneficial in reducing liver decompensation, even in the absence of virological response.

RESUMO

IgG4-related disease is a recently-described fibro-inflammatory condition with characteristic histopathological findings in the organs involved. The most commonly affected organs are pancreas, lymph nodes, and retroperitoneum. Liver disease usually involves bile structures and therefore IgG4-related disease is considered a cause of secondary sclerosing cholangitis. One out of three patients with IgG4 sclerosing cholangitis also presents autoimmune pancreatitis, although it can be associated with manifestations in other organs. One of the main features of IgG4-related disease is its good prognosis due to the great response to glucocorticoid therapy. However, relapse of the disease is not uncommon, especially when steroid therapy is decreased or stopped. Rituximab seems to be an effective treatment to achieve remission of the disease. We report the case of a 74 year-old man diagnosed with IgG4-related disease based on increase of serum IgG4 levels, imaging and histopathological findings, with systemic involvement including sclerosing cholangitis. Despite the absence of liver fibrosis at onset, the early use of glucocorticoids and rituximab therapy, the patient presented clinical and analytical deterioration, leading to secondary biliary cirrhosis. In conclusion, this clinical case highlights the importance of prompt diagnosis and therapeutics for sclerosing cholangitis secondary to IgG4-related disease in order to avoid progression of the disease and development of liver cirrhosis, as well as the refractory, aggressive nature of the disease in some cases as this one.
