Influence of language barrier and cultural background in hepatitis B disease knowledge in a Chinese community of Spain.

Introduction: Hepatitis B infection (HBV) is prevalent in China. Due to language barriers and cultural differences, it is not always straightforward to evaluate disease knowledge in liver clinics. We aimed to assess the awareness on HBV and its mechanisms of transmission in HBV-infected Chinese patients and their household contacts. Methods: HBV-infected Chinese patients and their contacts were interviewed by a native Chinese nurse regarding their knowledge on HBV transmission mechanisms, use of preventive measures and vaccination status. Non-Chinese HBV-infected patients and their household contacts served as a control group. Results: In total 182 patients and 398 contacts participated with 85 (47%) patients and 240 (60%) contacts being from China. Language barrier was reported in 80% of Chinese patients and 44% of their contacts. Knowledge on parenteral and sexual HBV transmission was high in all patients (~90%) but Chinese were more aware of vertical transmission than controls (94% vs. 68%; p < 0.01). Regarding the use of preventive measures, Chinese patients were more forewarned in their use to avoid parenteral transmission (93% vs. 74%, p < 0.01). When assessing household contacts, Chinese used preventive measures more frequently than controls for parenteral and sexual transmission (79% vs. 65 and 81% vs. 48%, p < 0.05). Vaccination coverage was slightly lower in Chinese contacts compared to controls (78% vs. 86%, p = 0.05). Conclusion: Despite relevant language barriers, Chinese patients are well informed on the mechanisms of HBV transmission. Cultural differences may explain a higher use of preventive measures among the Chinese population. HBV vaccination of household contacts should be reinforced in both groups.

Post-treatment LSM rather than change during treatment predicts decompensation in patients with cACLD after HCV cure.

BACKGROUND & AIMS: Baveno VII has defined a clinically significant (i.e., prognostically meaningful) liver stiffness measurement (LSM)-decrease in cACLD by ≥20% associated with a final LSM<20 kPa, or any decrease to <10 kPa. However, these rules have not yet been validated against direct clinical endpoints. METHODS: We retrospectively analysed cACLD patients (LSM≥10 kPa) with paired liver stiffness measurement (LSM) before (BL) and after (FU) HCV-cure by interferon-free therapies from 15 European centers. The cumulative incidence of hepatic decompensation was compared according to these criteria, considering hepatocellular carcinoma and non-liver-related death as competing risks. RESULTS: 2335 patients followed for a median of 6 years were analysed. Median BL-LSM was 16.6 kPa with 37.1% having ≥20 kPa. After HCV-cure, FU-LSM decreased to a median of 10.9 kPa (<10 kPa: 1002 [42.9%], ≥20 kPa: 465 [19.9%]) translating into a median LSM-change of -5.3 (-8.8-[-2.4])kPa corresponding to -33.9 (-48.0-[-15.9])%. Patients achieving a clinically significant decrease (65.4%) had a significantly lower risk of hepatic decompensation (subdistribution hazard ratio [SHR]: 0.12 [95%CI: 0.04-0.35], p<0.001). However, these risk differences were primarily driven by a negligible risk in patients with FU-LSM <10 kPa (5y-cumulative incidence: 0.3%) compared to a high risk in patients with FU-LSM ≥20 kPa (16.6%). Patients with FU-LSM 10-19.9 kPa (37.4%) also had a low risk of hepatic decompensation (5y-cumulative incidence: 1.7%), and importantly, the risk of hepatic decompensation did not differ between those with/without an LSM-decrease ≥20% (p=0.550). CONCLUSIONS: FU-LSM is key for risk stratification after HCV-cure and should guide clinical decision-making. LSM dynamics do not hold significant prognostic information in patients with FU-LSM 10-19.9 kPa, and thus, their consideration is not of sufficient incremental value in the specific context of HCV-cure.

Anticancer drugs are the first cause of drug-induced liver injury in a reference hospital.

Drug-induced liver injury (DILI) is a challenging liver disorder for hepatologists. We aimed to assess the pattern and causes of DILI in a tertiary hospital. We registered prospectively all patients referred with suspicion of DILI from 2018 to 2023. A total of 106 patients fulfilled the diagnostic criteria (30 caused by paracetamol were excluded; total number 76). The pattern of liver injury was hepatocellular in 55 (72%). Drugs causing DILI were antineoplastic (26%), antibiotics (24%), analgesics (12%), and recreational drugs (9%). Regarding clinical outcomes, 39 (51%) required hospitalization and 7 (9%) underwent a liver transplantation or died from acute liver injury. We identified 126 additional patients with DILI due to immune check-point inhibitors who were not referred to a liver disease specialist. Antineoplastic drugs have become the first cause of DILI in hospitals. A multidisciplinary approach and specific educational tools to increase DILI awareness are needed among different specialists.

Late presentation of chronic HBV and HCV patients seeking first time specialist care in Spain: a 2-year registry review.

Chronic viral hepatitis infection affects an estimated 325 million people globally. People who initiate treatment after significant disease progression face increased risk of severe liver complications and death. Data are scarce on the characteristics and risk factors of people who present late to care in Spain and globally. Data were collected from January 2018 to December 2019 to report late presentation (LP) to specialist care at 11 large university hospitals in Spain to assess related risk factors using a multivariable logistic regression model. 2290 (CHB = 505, CHC = 1785) patients were analysed, with 581 (25.2%) presenting late. Hepatitis C patients more frequently reported LP compared to hepatitis B patients (28.1% vs 15.0%; p < 0.001). Older age (p < 0.001), being male (p < 0.001), being Spanish-born (p < 0.001), and having an unknown origin of referral (p = 0.08) were associated with a higher likelihood of LP. Advanced liver disease was identified in 533 (23%) patients and late-stage liver disease in 124 (5.4%). LP, including with irreversible liver damage, to viral hepatitis specialist care is frequent in Spain, despite being a country with unrestricted treatment access. Initiatives to reduce LP should specifically target men, older individuals, foreign-born populations for CHB, and Spanish nationals for CHC.

Clinical, Molecular and Genetic Characteristics of Early Onset Gastric Cancer: Analysis of a Large Multicenter Study.

Gastric adenocarcinoma (GC) is a common tumor with high morbidity and mortality. Only 7% of patients with GC are diagnosed before age 50 (early onset gastric cancer (EOGC)), and their characteristics have been poorly described. We aimed to describe clinical, molecular, and genetic characteristics of EOGC. A total of 309 patients with EOGC were retrospectively studied in four Spanish centers. Personal information, family history, and tumor information were registered. Germinal genetic analysis was performed in patients who met current criteria of a hereditary syndrome at the time of diagnosis. The median age at diagnosis was 44 years. The majority (73.3%) of tumors were diffuse, and 78.3% were diagnosed in an advanced stage. Familial aggregation of GC was present in 18/117 (15.4%) cases, and 5/117 (4.3%) met criteria for familial GC. MMR-IHC was performed in 126/309 (40.7%) tumors: 4/126 (3.1%) had loss of expression in MLH1/PMS2, without an associated germline mutation. Sixteen germline genetic analyses were performed, detecting a pathogenic variant in four (25%) cases: one in BRCA2, one in TP53, and two in CDH1. Most EOGC are diffuse and diagnosed in an advanced stage. In these patients, DNA MMR system deficiency is uncommon. Although familial aggregation was observed in only 15% of cases, a germline mutation was found in 25% of patients tested with clinical criteria. This demonstrates that EOGC has a marked genetic heterogeneity, reinforcing the importance of an accurate genetic counseling and enhancing the emerging use of multigene panels.

Efficacy of an accelerated double-dose hepatitis B vaccine regimen in patients with cirrhosis.

The hepatitis B (HBV) vaccine is recommended in unvaccinated adults with cirrhosis, despite its low efficacy. We aimed to evaluate the response to a double-dose/accelerated vaccine schedule in patients with cirrhosis admitted into a hepatology ward. All patients with cirrhosis admitted to the hepatology ward without exclusion criteria were offered the HBV HBVAXPRO 40mcg vaccine at months 0, 1 and 2. Non-responders received a second cycle. We evaluated 468 patients and only 19% were seroprotected against HBV. In 196 patients without exclusion criteria for HBV vaccination, the per protocol response rate (anti-HBs >10 U/ml) was 23% after a first cycle and 59% after a second cycle. The overall response per intention to treat was only 23%. We have not identified predictors of response. Only one patient had a mild adverse event. Most patients with cirrhosis admitted in the hepatology ward are unprotected against HBV. Although a second HBV vaccination cycle increases the response rate, the poor overall response reinforces the implementation of HBV vaccination before the development of cirrhosis.

Direct-acting antiviral therapy improves kidney survival in hepatitis C virus-associated cryoglobulinaemia: the RENALCRYOGLOBULINEMIC study.

BACKGROUND: Direct-acting antiviral agents (DAAs) have shown high rates of sustained virological response in chronic hepatitis C virus (HCV) infection. However, the influence of DAAs on the course of kidney involvement in HCV-associated mixed cryoglobulinaemia (HCV-MC) has been little studied. The aim of this study was to analyse the effects of antiviral treatment on kidney prognosis and evolution in patients diagnosed with HCV-MC. METHODS: The RENALCRYOGLOBULINEMIC study is an observational multicentre cohort study of 139 patients with HCV-MC from 14 Spanish centres. Clinical and laboratory parameters were measured before and after antiviral treatment. Primary endpoints were kidney survival and mortality after HCV-MC diagnosis. Secondary endpoints were clinical, immunological and virological responses after antiviral treatment. RESULTS: Patients were divided into three groups based on the treatment received: treatment with DAAs (n = 100) treatment with interferon (IFN) and ribavirin (RBV) (n = 24) and no treatment (n = 15). Patients were followed up for a median duration of 138 months (interquartile range 70-251. DAA treatment reduced overall mortality {hazard ratio [HR] 0.12 [95% confidence interval (CI) 0.04-0.40]; P < 0.001} and improved kidney survival [HR 0.10 ( 95% CI 0.04-0.33); P < 0.001]. CONCLUSIONS: Results from the RENALCRYOGLOBULINEMIC study indicated that DAA treatment in patients with HCV-MC improves kidney survival and reduces mortality.

Low risk of hepatitis B reactivation in patients with severe COVID-19 who receive immunosuppressive therapy.

A significant proportion of patients infected with SARS-CoV-2 develop severe respiratory symptoms due to an excessive immune response. Treatment of this condition may include immunosuppressive therapies, such as IL-6 receptor antagonists and corticosteroids, which pose a risk for patients with active or past hepatitis B virus (HBV) infection. In this prospective cohort study, we analysed the risk of HBV reactivation in patients with severe COVID-19 and resolved HBV infection undergoing immunosuppressive therapy. From 15th March to 30th April 2020, 600 patients with severe COVID-19 were admitted to our hospital and treated with immune modulators. Data regarding HBV infection were available in 484, of whom 69 (14%) were HBsAg negative/anti-HBc positive. For these patients, HBV reactivation prophylaxis with entecavir was strongly recommended. Complete follow-up was available in 61 patients: 72% were male, median age was 67 years, and anti-HBs was >10 IU/mL in 72%. The immunosuppressive drug most used was tocilizumab (72%). Despite HBV prophylaxis recommendation, 38 (62%) patients received entecavir and 23 (38%) did not. Baseline features of both groups were similar. At follow-up, we found no cases of HBsAg seroreversion and only 2 (3%) patients (no prophylaxis group) had detectable serum HBV-DNA (<15 IU/mL). Both were anti-HBs negative and had normal aminotransferase levels. Our data show that the risk of HBV reactivation in patients with severe COVID-19 and resolved HBV infection undergoing immunosuppressive treatment is low. However, if a systematic follow-up after hospital discharge is unfeasible in patients without anti-HBs, a short course of antiviral prophylaxis may be a safe option.

Evaluación del cumplimiento a largo plazo de los indicadores de calidad en la esofagogastroduodenoscopia / Evaluation of long-term adherence to oesophagogastroduodenoscopy quality indicators

INTRODUCCIÓN: En un estudio previo demostramos que un pequeño programa de formación mejoraba los indicadores de calidad de la esofagogastroduodenoscopia (EGD) que llegaban a los estándares recomendados. Sin embargo, desconocemos el efecto de esta formación a largo plazo. El objetivo de este estudio fue valorar la calidad de las EGD después de 3años de haber realizado un programa de mejora. MATERIAL Y MÉTODOS: Estudio comparativo de 2 cohortes: EGD posteriores a un programa de formación realizado en 2016 (grupo A) y EGD en enero-marzo de 2019 (grupo B). El grupo B se dividió en 2 subgrupos: endoscopistas que habían participado en el programa de formación previo (B1) y los que no (B2). Se utilizaron los indicadores de calidad intraprocedimiento recomendados por la ASGE-ACG. RESULTADOS: Se analizaron un total de 1.236 EGD, 600 en el grupo A y 636 en el B (439 subgrupo B1 y 197 subgrupo B2). El número de exploraciones completas fue inferior en el grupo B (566 [94,3%] vs. 551 [86,6%]; p < 0,001). Se observó una disminución significativa en prácticamente todos los indicadores de calidad que, además, no alcanzaron los estándares recomendados: retroversión gástrica (96% vs. 81%; p < 0,001); protocolo de biopsias de Seattle (86% vs. 50%; p = 0,03), descripción de la lesión en la hemorragia (100% vs. 62%; p < 0,01), toma de ≥4 biopsias en sospecha de celiaquía (92,5% vs. 18%; p < 0,001), fotodocumentación de lesión (94% vs. 90%; p < 0,05). Cuando consideramos el global de la prueba (incluyendo la actuación correcta y la fotodocumentación adecuada), también se observó una disminución significativa (90,5% vs. 62%; p < 0,001). No hubo diferencias entre los subgrupos B1 y B2. CONCLUSIONES: La mejora observada en 2016 tras un programa de formación no perdura a los 3años. Es necesario hacer programas de formación continuados para mantener la calidad de la EGD por encima de los estándares recomendados

INTRODUCTION: In a previous study we demonstrated that a simple training programme improved quality indicators of Oesophagogastroduodenoscopy (OGD) achieving the recommended benchmarks. However, the long-term effect of this intervention is unknown. The aim of this study was to assess the quality of OGDs performed 3 years after of having completed a training programme. MATERIAL AND METHODS: A comparative study of 2 cohorts was designed as follows: Group A included OGDs performed in 2016 promptly after a training programme and Group B with OGDs performed from January to March 2019, this group was also divided into 2 subgroups: subgroup B1 of Endoscopists who had participated in the previous training programme and subgroup B2 of Endoscopists who had not. The intra-procedure quality indicators proposed by ASGE-ACG were used. RESULTS: A total of 1236 OGDs were analysed, 600 from Group A and 636 from Group B (439 subgroup B1 and 197 subgroup B2). The number of complete examinations was lower in Group B (566 [94.3%] vs. 551 [86.6%]; p < 0.001). A significant decrease was observed in nearly all quality indicators and they did not reach the recommended benchmarks: retroflexion in the stomach (96% vs. 81%; p < 0.001); Seattle biopsy protocol (86% vs. 50%; p = 0.03), description of the upper GI bleeding lesion (100% vs. 62%; p < 0.01), sufficient intestinal biopsy specimens (at least 4) in suspected coeliac disease (92.5% vs. 18%; p < 0.001), photo documentation of the lesion (94% vs. 90%; p < 0.05). Regarding the overall assessment of the procedure (including correct performance and adequate photo documentation), a significant decrease was also observed (90.5% vs. 62%; p < 0.001). There were no differences between subgroups B1 and B2. CONCLUSIONS: The improvement observed in 2016 after a training programme did not prevail after 3 years. In order to keep the quality of OGDs above the recommended benchmarks, it is necessary to implement continuous training programmes

Improvement of sexuality after hepatitis C cure with direct acting antivirals.

Despite rarely assessed, sexuality is a relevant domain in Quality of Life. We prospectively evaluated the impact of direct-acting antiviral therapy on sexuality in a cohort of 186 patients with chronic hepatitis C (HCV). Sexual dysfunction was assessed by validated scales CSFQ-14/CSFQ-VAS at baseline and one year after treatment finalization. Median age was 55 years and 87% had mild liver disease. Basal prevalence of sexual dysfunction (62%) and fear of HCV transmission (25%) were high. After HCV cure, both sexual dysfunction prevalence and CSFQ-VAS improved (P = .058 and P < .01, respectively), and fear of HCV transmission dropped to 16% (P = .02). These changes were especially relevant in young men (<55), where sexual dysfunction decreased from 48.6% to 29.7% (P = .04) and among non-depressed patients in whom sexual dysfunction decreased from 54.6% to 47% (P < .01). Age and major depression remained as independent factors of sexual dysfunction persistence after HCV cure. Our data suggest that HCV eradication is associated with an improvement in sexuality, in those patients without depression.

Plasma Exchange: An Effective Rescue Therapy in Critically Ill Patients With Coronavirus Disease 2019 Infection.

OBJECTIVES: Infection by severe acute respiratory syndrome coronavirus-2 can induce uncontrolled systemic inflammation and multiple organ failure. The aim of this study was to evaluate if plasma exchange, through the removal of circulating mediators, can be used as rescue therapy in these patients. DESIGN: Single center case series. SETTING: Local study. SUBJECTS: Four critically ill adults with coronavirus disease 19 pneumonia that failed conventional interventions. INTERVENTIONS: Plasma exchange. Two to six sessions (1.2 plasma volumes). Human albumin (5%) was used as the main replacement fluid. Fresh frozen plasma and immunoglobulins were administered after each session to avoid coagulopathy and hypogammaglobulinemia. MEASUREMENTS AND MAIN RESULTS: Serum markers of inflammation and macrophage activation. All patients showed a dramatic reduction in inflammatory markers, including the main cytokines, and improved severity scores after plasma exchange. All survived to ICU admission. CONCLUSIONS: Plasma exchange mitigates cytokine storm, reverses organ failure, and could improve survival in critically ill patients with coronavirus disease 2019 infection.

Hepatitis C-related cirrhosis will be a marginal cause of hospital admissions by 2025.

BACKGROUND & AIMS: Complications of cirrhosis are the main cause of hospital admissions in liver units. In areas where HCV is prevalent, most of these admissions are attributable to HCV-related cirrhosis (HCV-cirrhosis). This study assessed the impact of direct-acting antivirals (DAA) in the profile of patients with liver disease admitted to a referral liver unit from a university hospital. METHODS: We registered hospital admissions resulting from cirrhosis to the Liver Unit of the Hospital Clinic of Barcelona, from 2011 to 2014 (pre-DAA period) and from 2015 to 2019 (post-DAA period). RESULTS: From a total of 14,865 hospital admissions, 10,053 resulted from cirrhosis (corresponding to 6,272 patients). The number and proportion of hospital admissions because of HCV-cirrhosis remained stable during the period 2011-2014 (525 per year, 48.8% of the total), but decreased progressively after 2015 (p <0.001), reaching <300 (27.1%) admissions in 2019. Similarly, HCV-cirrhosis accounted for 3,885 inpatient days per year (44.9%) during the pre-DAA period and decreased steadily after 2015 (p >0.001), reaching only 1,909 inpatient days (22%) in 2019. The figures for intensive care unit admissions followed a similar pattern. By means of a slope analysis (binomial regression model), we predicted that HCV-cirrhosis hospital admissions will be residual by 2025 (2.3%, 95% CI 0-10.9%). By contrast, we observed a significant increase in hospital admissions because of metabolic-associated fatty liver disease (5-fold) and autoimmune hepatitis (4-fold) during the study period. CONCLUSIONS: In summary, our data showed a profound reduction in HCV-cirrhosis hospitalisation burden since 2015, coincident with the wide use of DAAs in Spain. Our predictions suggest that, by 2025, HCV-cirrhosis will be a marginal cause of hospital admissions for patients with liver disease. LAY SUMMARY: Over the past few years, the wide use of antiviral drugs that cure HCV has had a significant effect on patients being admitted to hospital. Most patients with HCV and cirrhosis are treated (and often cured) in the community and, thus, the number of hospital admissions because of severe forms of HCV has decreased drastically. HCV is no longer the first cause of admission into liver units and, in only a few years from now, it is likely to be only a residual cause of hospitalisation.

Resolution of subclinical porphyria cutanea tarda after hepatitis C eradication with direct-acting anti-virals.

BACKGROUND: Hepatitis C virus (HCV) is a risk factor for porphyria cutanea tarda (PCT), a rare disease originating in the liver characterised by overproduction of porphyrins. Although hepatitis C infection is highly prevalent among patients with porphyria, only a minority of hepatitis C patients develop PCT. AIMS: To explore the presence of porphyrin abnormalities in a cohort of asymptomatic hepatitis C-infected patients and the impact of anti-viral therapy. METHODS: Eighty-four consecutive patients with HCV infection treated with direct-acting antivirals after 1 January 2018 were longitudinally evaluated for the presence of porphyrin abnormalities. Those patients with biochemical abnormalities at baseline were additionally evaluated at follow-up. Porphyrins in urine were screened by fluorometry and isomer separation was performed by liquid chromatography. RESULTS: In five patients, all of them asymptomatic, porphyrin profile abnormalities were detected: three presented significant increased urinary porphyrins with a typical PCT profile, and two showed normal levels of urinary porphyrins, but abnormal porphyria-like profiles. Urine evaluation after hepatitis C cure showed complete normalisation of the urinary porphyrins in all patients, confirming the biochemical cure of the disease. CONCLUSIONS: We document the existence of rare cases of hepatitis C-infected patients with significant uroporphyrinuria in the absence of dermatological manifestations. Anti-viral therapy normalises the biochemical disorder, preventing patients from presenting PCT associated complications.

Efficacy and safety of direct-acting antivirals in older patients with cirrhosis and high comorbidity index.

OBJECTIVE: There is scarce data with regard to the effectiveness and safety of direct-acting antivirals and possible drug-drug interactions between antiviral therapy and the multiple drugs frequently assumed by older patients. The aim is to evaluate the impact of comorbidities and drug-drug interactions on the efficacy and tolerability of direct-acting antivirals in this population. METHODS: Observational retrospective study of patients at least 65 years old receiving all-oral antiviral therapy between April 2015 and March 2016. RESULTS: Two hundred sixty-one patients were identified. Age distribution: 65-74 (73.9%), 75-79 (18.4%) and ≥80 (7.7%) years. Average age was 71 years, 38.7% were male, and 90% of patients took concomitant medication (43% patients taking ≥ 5 medicines). Predicted clinically significant drug-drug interactions were present in 72.8% of patients. The sustained viral response 12 weeks after end of treatment was 96.9%. Patients with serious adverse events received more concomitant drugs and all of them presented a clinical risk group ≥06/5. CONCLUSIONS: Direct antiviral agents are highly effective also in older patients with advanced liver disease, comorbidities and concomitant medications. Serious adverse events increased with the number of concomitant medications and the severity of comorbidity. A clinical risk group score ≥06/5 may help to decide the indication of antiviral therapy in this difficult-to-treat population.

Low seroprevalence and zero incidence rate of hepatitis E in men who have sex with men during a hepatitis A outbreak.

Hepatitis E virus (HEV) and hepatitis A virus (HAV) are both secreted in feces. Despite HEV transmission in Europe is mainly zoonotic, person-to-person transmission has not been completely excluded. Men who have sex with men (MSM) constitute a high-risk group for HAV mostly due to oral sex. We investigated the potential transmission of HEV during an acute hepatitis A (AHA) outbreak mainly affecting MSM. One hundred and two patients were diagnosed with AHA. Sixty-nine (68%) self-reported to be MSM, 75% of whom had high-risk sexual behaviors and 46% had suffered previous sexually transmitted diseases. We collected serum from 85 (83%) patients during AHA. HEV-IgG seroprevalence was not different among MSM (7%) compared with non-MSM (8%) patients. Two patients had positive anti-HEV-IgM, but all samples tested negative for HEV-RNA. These results suggest that HEV does not spread by sexual contact or person-to-person in our area.

Simplified follow-up of patients with mild chronic hepatitis C in areas with limited access to antiviral therapy.

BACKGROUND AND AIMS: In some areas of the world, antiviral therapy for chronic hepatitis C (CHC) is not available for all patients. The optimal interval for liver stiffness measures (LSM) and noninvasive scores to assess fibrosis progression has not been studied. We evaluated the usefulness of consecutive LSM, APRI, FIB-4 and Forns scores to predict disease progression. METHODS: Patients with CHC and at least two annual LSM within 3 years were followed for a minimum of 5 years. Noninvasive scores were assessed. Evolution of LSM and scores were expressed as change/year (Delta). RESULTS: 623 non-cirrhotic patients were included. Median baseline LSM was 6.6 kPa (IQR 5.4-8.4). During a median follow-up of 6 years, 61(9.7%) patients developed cirrhosis. Baseline LSM ≥ F2 and Forns ≥ 6.9 were the main predictors of cirrhosis (C-index 0.97). The addition of Delta variables did not improve its prediction. In patients with mild fibrosis (F0-1), progression to ≥F2 occurred in 80 (23%) within the first 3 years. Baseline BMI ≥ 24 kg/m2 and LSM ≥ 5.9 kPa were associated to progression. CONCLUSIONS: Baseline LSM and Forns are highly predictive of cirrhosis development. In patients with mild CHC, BMI < 24 and LSM < 5.9, the likelihood of progression is very low, allowing for a significant spacing of noninvasive assessments over time.
