Hepatol Int 2022; 16:1318-1329. [PMID: 36074319 DOI: 10.1007/s12072-022-10402-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Accepted: 07/09/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND The increasing number of direct-acting antiviral (DAA) regimens along with limited number of subjects and co-medications involved in clinical trials results in drug-drug interactions (DDIs) with DAAs is to be determined. We aimed to examine the prevalence and degree of DDIs between DAAs and other co-medications in a territory-wide cohort of chronic hepatitis C virus (HCV) patients. METHODS DDIs were assigned to three risk categories: Category 1-no clinically significant DDI; category 2-potential clinically significant interaction (monitoring and caution required); category 3-contraindicated (should not be co-administered). RESULTS Of 2981 patients (mean age 59.3 ± 12.3 years; male 60.6%), 810 (48.8%) had genotype 1 and 552 (33.2%) genotype 6 HCV among the 1661 patients with HCV genotype tested; 769 (25.8%) received sofosbuvir/velpatasvir, 510 (17.1%) sofosbuvir/ledipasvir, and 865 (29.0%) glecaprevir/pibrentasvir. More than one-fourth (26.3%) of the patients have polypharmacy (≥ 3 co-medications) in all patients, 27.0% in patients received sofosbuvir/velpatasvir, 25.1% in elbasvir/grazoprevir, and 21.2% in glecaprevir/pibrentasvir. 2037 (68.3%) patient experienced DDI (Category 2: 53.1%; Category 3: 15.2%). The commonest drugs leading to DDIs were calcium channel blockers (31.5%) and proton pump inhibitors (23.0%) in category 2; statins (10.2%), antiplatelet/anticoagulants (3.0%) and antipsychotics (2.9%) in category 3. Changing medication was the most common response from physicians in both category 2 and 3 DDIs. CONCLUSION The commonest co-medications leading to contraindication during DAA treatment were statins and antipsychotics. Category 2 and 3 DDIs are often managed by appropriate dose adjustments or temporary discontinuation of relevant co-medications. Careful assessment for potential DDI before DAA use is mandatory to avoid potential harmful effects.

Abstract
BACKGROUND Universal vaccination of newborns with hepatitis B virus (HBV) vaccine is the most important strategy to prevent chronic HBV infection and its complications of which hepatocellular carcinoma (HCC) as the deadliest. AIMS To evaluate the impact of universal HBV vaccination on the prevalence of chronic HBV infection, and the incidences of HCC and hepatic events in young adults born before and after the introduction of the universal HBV vaccination programme in 1988 in Hong Kong METHODS: This was a territory-wide retrospective observational cohort study of consecutive adult subjects born in 1970-2002 with hepatitis B surface antigen (HBsAg) checked. Subjects born during the vaccination era (1988-2002) were included in the vaccinated cohort; subjects born between 1970 and 1987 were included in the unvaccinated cohort. RESULTS We included 695,925 subjects for HBV prevalence analysis. Chronic HBV infection dropped from 14.3% in subjects born in 1970, to 6.7% in subjects born in 1988. In total, 53,960 vaccinated and 318,290 unvaccinated subjects who had available clinical data were included for event analysis. HCC and hepatic events occurred in 44 (0.1%) and 75 (0.1%) of the vaccinated subjects and in 1305 (0.4%) and 1806 (0.6%) of the unvaccinated subjects, respectively. All incidence rates remained numerically lower in vaccinated subjects after adjustment for age, gender and antiviral treatment, but failed to reach statistical significance due to very low incidence rates. CONCLUSIONS Universal HBV vaccination markedly reduces the prevalence of chronic HBV infection and may contribute to the decreased incidences of HCC and hepatic events.

Abstract
World Health Organization (WHO) calls for global hepatitis strategy to eliminate viral hepatitis by 2030. Yet many high-income countries were unable to achieve HCV elimination by 2030. Apart from the tremendous efforts and resources from the governments, many non-government organizations (NGOs) have been working very hard to contribute to HCV elimination. In Hong Kong, the Center for Liver Health of The Chinese University of Hong Kong (CUHK) has been working very closely with various NGOs to educate and screen subjects who previously use intravenous drugs. In this review article, we discussed in details the New Life New Liver Program, and the barriers to HCV elimination, with special highlight the role of NGOs in overcoming the barriers.

Wang Y, Cheng G, Lau G. Achieving WHO target of HCV control in Hong Kong: challenges and strategies. Glob Health Med 2021; 3:276-282. [PMID: 34782869 DOI: 10.35772/ghm.2021.01075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 07/26/2021] [Accepted: 08/03/2021] [Indexed: 11/08/2022]
Abstract
With the introduction of effective directly acting antiviral agents (DAAs) therapy, control and elimination of hepatitis C virus (HCV) infection is becoming a feasible goal. In Hong Kong, HCV prevalence in general population is 0.3%-0.5% over the past decades. However, like other high-income areas/countries, high prevalence of HCV infection has been found in several population groups, such as people who inject drugs (PWID), patients undergoing dialysis, and human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/ AIDS) patients. Based on the epidemiological study using data retrieved from the Hong Kong HCV Registry from January 2005 to March 2017, the estimated territory-wide diagnosis rate and treatment rate of HCV infection were only 50.9% and 12.4%, respectively. Although these rates was comparable to many developed countries/areas, the performances remained substantially below 90% and 80%, the 2030 targets proposed by World Health Organization (WHO). In recognition of the challenges, the Hong Kong Government set up the Steering Committee on Prevention and Control of Viral Hepatitis (SCVH) which formulated the Hong Kong Viral Hepatitis Action Plan 2020-2024. The Action Plan adopts four key strategies, as described in the WHO framework for global action, namely, awareness, surveillance, prevention and treatment. With the effective implementation of the Action Plan, especially in targeted screening of high-risk populations and more generalized use of the highly efficacious DAAs for all diagnosed HCV subjects, the goals of reducing HCV transmission and HCV-related morbidity and mortality can be achieved in Hong Kong by 2030.

Abstract
BACKGROUND AND AIMS We compared risk of acute liver injury and mortality in patients with COVID-19 and current, past, and no HBV infection. APPROACH AND RESULTS This was a territory-wide retrospective cohort study in Hong Kong. Patients with COVID-19 between January 23, 2020, and January 1, 2021, were identified. Patients with hepatitis C or no HBsAg results were excluded. The primary outcome was mortality. Acute liver injury was defined as alanine aminotransferase or aspartate aminotransferase ≥2 × upper limit of normal (ULN; i.e., 80 U/L), with total bilirubin ≥2 × ULN (i.e., 2.2 mg/dL) and/or international normalized ratio ≥1.7. Of 5,639 patients included, 353 (6.3%) and 359 (6.4%) had current and past HBV infection, respectively. Compared to patients without known HBV exposure, current HBV-infected patients were older and more likely to have cirrhosis. Past HBV-infected patients were the oldest, and more had diabetes and cardiovascular disease. At a median follow-up of 14 (9-20) days, 138 (2.4%) patients died; acute liver injury occurred in 58 (1.2%), 8 (2.3%), and 11 (3.1%) patients with no, current, and past HBV infection, respectively. Acute liver injury (adjusted HR [aHR], 2.45; 95% CI, 1.52-3.96; P < 0.001), but not current (aHR, 1.29; 95% CI, 0.61-2.70; P = 0.507) or past (aHR, 0.90; 95% CI, 0.56-1.46; P = 0.681) HBV infection, was associated with mortality. Use of corticosteroid, antifungal, ribavirin, or lopinavir-ritonavir (adjusted OR [aOR], 2.55-5.63), but not current (aOR, 1.93; 95% CI, 0.88-4.24; P = 0.102) or past (aOR, 1.25; 95% CI, 0.62-2.55; P = 0.533) HBV infection, was associated with acute liver injury. CONCLUSION Current or past HBV infections were not associated with more liver injury and mortality in COVID-19.

[PMID: 34099979 PMCID: PMC8135402 DOI: 10.1093/ofid/ofab205] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 04/19/2021] [Indexed: 02/07/2023] Open
Abstract
Background Liver injury in patients with coronavirus disease 2019 (COVID-19) is common and prognostic. Direct viral tropism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for angiotensin-converting enzyme 2 receptors in hepatocytes may be one of the mechanisms of liver injury. We aimed to determine the role of viral persistence of SARS-CoV-2, based on cycle threshold (Ct) value, in liver injury in COVID-19. Methods This was a territory-wide retrospective cohort study of all public hospitals in Hong Kong. Laboratory-confirmed COVID-19 was identified. Serial liver biochemistries and Ct values of SARS-CoV-2 RNA were analyzed. Results We identified 7622 COVID-19 patients (mean age, 47 years; 48.2% male) diagnosed from March 24 to January 1, 2021, who had serial liver biochemistries and Ct values. A total of 1363 (17.9%) COVID-19 patients had alanine transferase (ALT)/aspartate aminotransferase (AST) elevations with 2 temporal patterns—early (within first 14 days of symptom onset) and late (>14 days from symptom onset). COVID-19 patients with ALT/AST elevations had a lower Ct value at admission (23 vs 25; P < .001), day 5 (24 vs 26; P < .001), and day 20 (31 vs 32; P < .001) after admission, compared with those without ALT/AST elevations. COVID-19 patients with ALT/AST elevations had a longer duration from first positive to first negative reverse transcription polymerase chain reaction test for SARS-CoV-2 (13 vs 9 days; P < .001). ALT/AST elevation and presence of diabetes were independent risk factors of viral persistence. Conclusions Liver injury in COVID-19 is linked to a higher SARS-CoV-2 viral load during the early phase of infection, signifying a possible direct viral injury to the liver. Prolonged viral persistence of SARS-CoV-2 is associated with liver injury.

Abstract
BACKGROUND The burden of hepatitis C virus (HCV) infection among people who use drugs (PWUDs) is considerable. We aimed to screen for HCV infection using the fingerstick dried blood spot (DBS) test and to describe the cascade of hepatitis C care among PWUDs in Madrid, Spain. We also evaluated the prevalence of hepatitis B virus (HBV) and hepatitis D virus (HDV) in this population. METHODS We carried out a prospective study and collected samples and epidemiological data using a mobile unit. Viral infections were tested by immunoassay and RT-PCR assay. PWUDs with a positive result were contacted and referred to a specialized health center to confirm and treat the HCV infection. RESULTS We studied 529 PWUD samples; 49.7% were from persons who had previously used injection drugs (IDUs). Of these, 152 (28.7%) were positive for HCV antibodies, 122 (23.1%) for HCV RNA, 23 (4.3%) for HBsAg, and two (0.4%) for HDV antibodies (8.7% of those with hepatitis B). People who inject drugs (PWID) more frequently had positive HCV antibody titers (52% vs. 7.3%; p<0.001) and a positive HCV RNA test result (40.2% vs. 7.3%; p<0.001) than non-PWID. The time from sample collection to test results was 19 days. The next 104 individuals (85.2%) with active HCV infection were contacted to report their HCV test results. Of these, 63 (51.6%) had an appointment, 62 (50.8%) were evaluated in the hospital, and 56 (45.9%) started HCV therapy. CONCLUSION HCV screening using fingerstick DBS was an excellent tool for determining HCV prevalence and other chronic hepatitis viruses (HBV and HDV) in PWUDs. However, linkage to care was limited, mainly with respect to the initiation of HCV therapy.

Abstract
Background Because of high-risk behaviours, sedentary lifestyle and side effects of medications, psychiatric patients are at risk of viral hepatitis, alcohol-related liver disease and non-alcoholic fatty liver disease. We aimed to study the incidence of hepatocellular carcinoma (HCC) and cirrhotic complications in psychiatric patients. Methods We identified consecutive adult patients in all public hospitals and clinics in Hong Kong with psychiatric diagnoses between year 2003 and 2007 using the Clinical Data Analysis and Reporting System, which represents in-patient and out-patient data of approximately 80% of the 7.4-million local population. The patients were followed for liver-related events (HCC and cirrhotic complications) and deaths until December 2017. Age- and sex-standardized incidence ratio (SIR) of HCC in psychiatric patients to the general population was estimated by Poisson model. Results We included 105,763 psychiatric patients without prior liver-related events in the final analysis. During a median (interquartile range) follow-up of 12.4 (11.0–13.7) years, 1461 (1.4%) patients developed liver-related events; 472 (0.4%) patients developed HCC. Compared with the general population, psychiatric patients had increased incidence of HCC (SIR 1.42, 95% confidence interval [CI] 1.28–1.57, P < 0.001). The SIR was highest in patients with drug-induced (SIR 3.18, 95% CI 2.41–4.11, P < 0.001) and alcohol-induced mental disorders (SIR 2.98, 95% CI 2.30–3.81, P < 0.001), but was also increased in patients with psychotic disorders (SIR 1.39, 95% CI 1.16–1.65, P < 0.001) and mood disorders (SIR 1.16, 95% CI 1.00–1.34, P = 0.047). Liver disease was the fifth most common cause of death in this population, accounting for 595 of 10,614 (5.6%) deaths. Importantly, 569 (38.9%) patients were not known to have liver diseases at the time of liver-related events. The median age at HCC diagnosis (61 [range 26–83] years) was older and the median overall survival (8.0 [95% CI 5.0–10.9] months) after HCC diagnosis was shorter in this cohort of psychiatric patients than other reports from Hong Kong. Conclusions HCC, cirrhotic complications, and liver-related deaths are common in psychiatric patients, but liver diseases are often undiagnosed. More efforts are needed to identify liver diseases in the psychiatric population so that treatments and screening for HCC and varices can be provided to patients in need.
