- BACKGROUND: Previous studies on hepatitis C cascade of care have been mainly focused on diagnosis and treatment rate, while less attention has been given to patients lost to follow-up (LTFU) after diagnosis. Analyses of this latter issue on population level are missing.AIMS: In this nationwide study of people with HCV, we aimed to estimate the proportion LTFU after HCV diagnosis, characterize them, and analyze their other healthcare contacts.METHODS: Patients diagnosed with chronic HCV in the Swedish National Patient register during 2001-2011 and still alive December 31, 2013, were included. The number of cured patients without need of follow-up was estimated. Visits to HCV specialist care during 2012-2013 were analysed. For those LTFU, other specialist care contacts were studied.RESULTS: In total 29,217 patients were included, with 24,733 with need of HCV care. 61% (n=15,007) of them were LTFU from HCV care in 2012-2013 and 58% did not attend HCV care during the second year after HCV diagnosis. The departments of surgery/orthopedic or psychiatry/dependency were the most common other non-primary healthcare contacts. Predictors for LTFU were young age, male sex, low education, presence of psychiatric/dependency diagnosis, unmarried, and longer duration since diagnosis of HCV.CONCLUSIONS: This study showed that almost two-thirds of patients were LTFU after HCV diagnosis, with frequent occurrence early after diagnosis. Efforts to link patients back to HCV care, in combination with early and easy access to HCV treatment and harm reduction, are necessary to reach the HCV elimination goal.

- 2022
-
In: Liver international (Print). - Chichester, United Kingdom : John Wiley & Sons. - 1478-3223 .- 1478-3231. ; 42:7, s. 1546-1556

Journal article (peer-reviewed)abstract
- Background and Aims: The presence of advanced hepatic fibrosis is the prime marker for the prediction of liver-related complications in non-alcoholic fatty liver disease (NAFLD). Blood-based non-invasive tests (NITs) have been developed to evaluate fibrosis and identify patients at risk. Current guidelines propose monitoring the progression of NAFLD using repeated NITs at 2-3-year intervals. The aim of this study was to evaluate the association of changes in NITs measured at two time points with the progression of NAFLD.Methods. We retrospectively included NAFLD patients with NIT measurements in whom the baseline hepatic fibrosis stage had been assessed by biopsy or transient elastography (TE). Subjects underwent follow-up visits at least 1 year from baseline to evaluate the progression of NAFLD. NAFLD progression was defined as the development of end-stage liver disease or fibrosis progression according to repeat biopsy or TE. The following NITs were calculated at baseline and follow-up: Fibrosis-4 (FIB-4), NAFLD fibrosis score (NFS), aspartate aminotransferase to platelet ratio index (APRI) and dynamic aspartate-to-alanine aminotransferase ratio (dAAR).Results: One hundred and thirty-five patients were included with a mean follow-up of 12.6 +/- 8.5 years. During follow-up, 41 patients (30%) were diagnosed with progressive NAFLD. Change in NIT scores during follow-up was significantly associated with disease progression for all NITs tested except for NFS. However, the diagnostic precision was suboptimal with area under the receiver operating characteristics 0.56-0.64 and positive predictive values of 0.28-0.36 at sensitivity fixed at 90%.Conclusions: Change of FIB-4, NFS, APRI, and dAAR scores is only weakly associated with disease progression in NAFLD. Our findings do not support repeated measurements of these NITs for monitoring the course of NAFLD.

Impact on follow-up strategies in patients with primary sclerosing cholangitis
- 2023
-
In: Liver international (Print). - Chichester, United Kingdom : Wiley-Blackwell Publishing Inc.. - 1478-3223 .- 1478-3231. ; 43:1, s. 127-138
-
Journal article (peer-reviewed)abstract
- BACKGROUND & AIMS: Evidence for the benefit of scheduled imaging for early detection of hepatobiliary malignancies in primary sclerosing cholangitis (PSC) is limited. We aimed to compare different follow-up strategies in PSC with the hypothesis that regular imaging improves survival.METHODS: We collected retrospective data from 2,975 PSC patients from 27 centers. Patients were followed from the start of scheduled imaging or in case of clinical follow-up from January 1, 2000, until death or last clinical follow-up alive. The primary endpoint was all-cause mortality.RESULTS: A broad variety of different follow-up strategies were reported. All except one center used regular imaging, ultrasound (US) and/or magnetic resonance imaging (MRI). Two centers used scheduled ERCP in addition to imaging for surveillance purposes. The overall HR (CI95%) for death, adjusted for sex, age and start year of follow-up, were 0.61 (0.47-0.80) for scheduled imaging with and without ERCP; 0.64 (0.48-0.86) for US/MRI and 0.53 (0.37-0.75) for follow-up strategies including scheduled ERCP. The lower risk of death remained for scheduled imaging with and without ERCP after adjustment for cholangiocarcinoma (CCA) or high-grade dysplasia as a time-dependent covariate, HR 0.57 (0.44-0.75). Hepatobiliary malignancy was diagnosed in 175 (5.9%) of the patients at 7.9 years follow-up. Asymptomatic patients (25%) with CCA had better survival if scheduled imaging had been performed.CONCLUSIONS: Follow-up strategies vary considerably across centers. Scheduled imaging was associated with improved survival. Multiple factors may contribute to this result including early tumor detection and increased endoscopic treatment of asymptomatic benign biliary strictures.

Hepatitis C Elimination in Sweden : Progress, Challenges and Opportunities for Growth in the time of COVID-19
- 2021
-
In: Liver international. - : Wiley-Blackwell Publishing Inc.. - 1478-3223 .- 1478-3231. ; 41:9, s. 2024-2031
-
Journal article (peer-reviewed)abstract
- BACKGROUND & AIMS: In 2014, the burden of hepatitis C virus (HCV) in Sweden was evaluated, to establish a baseline and inform public health interventions. Considering the changing landscape of HCV treatment, prevention, and care, and in light of the COVID-19 pandemic, this analysis seeks to evaluate Sweden's progress toward the WHO elimination targets and identify remaining barriers.METHODS: The data used for modeling HCV transmission and disease burden in Sweden were obtained through literature review, unpublished sources, and expert input. A dynamic Markov model was employed to forecast population sizes and incidence of HCV through 2030. Two scenarios ("2019 Base" and "WHO Targets") were developed to evaluate Sweden's progress toward HCV elimination.RESULTS: At the beginning of 2019, there were 29,700 (95% UI: 19,300 - 33,700) viremic infections in Sweden. Under the base scenario, Sweden would achieve and exceed the WHO targets for diagnosis, treatment, and liver-related death. However, new infections would decrease by less than 10%, relative to 2015. Achieving all WHO targets by 2030 would require 1) expanding harm reduction programs to reach more than 90% of PWID and 2) treating 90% of HCV+ PWID engaged in harm reduction programs and ≥7% of PWID not involved in harm reduction programs, annually by 2025.CONCLUSIONS: It is of utmost importance that Sweden, and all countries, find sustainability in HCV programs by broadening the setting and base of providers to provide stability and continuity of care during turbulent times.

Serum aromatic and branched-chain amino acids associated with NASH demonstrate divergent associations with serum lipids
- 2021
-
In: Liver International. - : Wiley. - 1478-3223 .- 1478-3231. ; 41:4, s. 754-763
-
Journal article (peer-reviewed)abstract
- Background & Aims: Non-alcoholic fatty liver disease (NAFLD) has been associated with multiple metabolic abnormalities. By applying a non-targeted metabolomics approach, we aimed at investigating whether serum metabolite profile that associates with NAFLD would differ in its association with NAFLD-related metabolic risk factors. Methods & Results: A total of 233 subjects (mean ± SD: 48.3 ± 9.3 years old; BMI: 43.1 ± 5.4 kg/m2; 64 male) undergoing bariatric surgery were studied. Of these participants, 164 with liver histology could be classified as normal liver (n = 79), simple steatosis (SS, n = 40) or non-alcoholic steatohepatitis (NASH, n = 45). Among the identified fasting serum metabolites with higher levels in those with NASH when compared to those with normal phenotype were the aromatic amino acids (AAAs: tryptophan, tyrosine and phenylalanine), the branched-chain amino acids (BCAAs: leucine and isoleucine), a phosphatidylcholine (PC(16:0/16:1)) and uridine (all FDRp < 0.05). Only tryptophan was significantly higher in those with NASH compared to those with SS (FDRp < 0.05). Only the AAAs tryptophan and tyrosine correlated positively with serum total and LDL cholesterol (FDRp < 0.1), and accordingly, with liver LDLR at mRNA expression level. In addition, tryptophan was the single AA associated with liver DNA methylation of CpG sites known to be differentially methylated in those with NASH. Conclusions: We found that serum levels of the NASH-related AAAs and BCAAs demonstrate divergent associations with serum lipids. The specific correlation of tryptophan with LDL-c may result from the molecular events affecting LDLR mRNA expression and NASH-associated methylation of genes in the liver.

Genetic variants in the MTHFR are not associated with fatty liver disease.
- 2020
-
In: Liver international : official journal of the International Association for the Study of the Liver. - : Wiley. - 1478-3231. ; 40:8, s. 1934-1940
-
Journal article (peer-reviewed)abstract
- The common missense sequence variants of methylenetetrahydrofolate-reductase (MTHFR), rs1801131 (c.A1298C) and rs1801133 (c.C677T), favor the development of hyperhomocysteinemia and diminished DNA methylation. Previous studies, carried out in small series and with suboptimal characterization of the hepatic phenotype, tested the association of these genetic variants with fatty liver disease (FLD), with conflicting results. Here, we assessed the association of rs1801131 and rs1801133 with hepatic phenotype in the Liver Biopsy Cross-Sectional Cohort, a large cohort (n=1375 from Italy and 411 from Finland) of European individuals with suspect FLD associated with dysmetabolism. A total of 1786 subjects were analyzed by ordinal regression analyses. The rs1801131 and the rs1801133 variants were not associated with steatosis, inflammation, ballooning, or fibrosis. The present study suggests that changes in folate and methionine metabolism resulting from these 2 variants are not associated with a clinically significant impact on FLD in Europeans.

Journal article (peer-reviewed)abstract
- Background Bile acids (BAs) regulate hepatic lipid metabolism and inflammation. Bile salt export pump (BSEP) KO mice are metabolically preconditioned with a hydrophilic BA composition protecting them from cholestasis. We hypothesize that changes in hepatic BA profile and subsequent changes in BA signalling may critically determine the susceptibility to steatohepatitis. Methods Wild-type (WT) and BSEP KO mice were challenged with methionine choline-deficient (MCD) diet to induce steatohepatitis. Serum biochemistry, lipid profiling as well as intestinal lipid absorption were assessed. Markers of inflammation, fibrosis, lipid and BA metabolism were analysed. Hepatic and faecal BA profile as well as serum levels of the BA synthesis intermediate 7-hydroxy-4-cholesten-3-one (C4) were also investigated. Results Bile salt export pump KO MCD-fed mice developed less steatosis but more inflammation than WT mice. Intestinal neutral lipid levels were reduced in BSEP KO mice at baseline and under MCD conditions. Faecal non-esterified fatty acid concentrations at baseline and under MCD diet were markedly elevated in BSEP KO compared to WT mice. Serum liver enzymes and hepatic expression of inflammatory markers were increased in MCD-fed BSEP KO animals. PPAR alpha protein levels were reduced in BSEP KO mice. Accordingly, PPAR alpha downstream targets Fabp1 and Fatp5 were repressed, while NF kappa B subunits were increased in MCD-fed BSEP KO mice. Farnesoid X receptor (FXR) protein levels were reduced in MCD-fed BSEP KO vs WT mice. Hepatic BA profile revealed elevated levels of T beta MCA, exerting FXR antagonistic action, while concentrations of TCA (FXR agonistic function) were reduced. Conclusion Presence of hydroxylated BAs result in increased faecal FA excretion and reduced hepatic lipid accumulation. This aggravates development of MCD diet-induced hepatitis potentially by decreasing FXR and PPAR alpha signalling.

Journal article (peer-reviewed)abstract
- Farnesoid X receptor (FXR) plays a key role in bile acid and lipid homeostasis. Experimental evidence suggests that it can modulate liver damage related to nonalcoholic fatty liver disease (NAFLD). We examined the impact of the NR1H4 rs35724 G>C, encoding for FXR, on liver damage in a large cohort of patients at risk of steatohepatitis.We considered 2,660 consecutive individuals at risk of steatohepatitis with liver histology. The rs35724 G>C polymorphisms were genotyped by TaqMan assays. Gene expression was evaluated by RNASeq in a subset of patients (n=124).The NR1H4 rs35724 CC genotype, after adjusting for clinic-metabolic and genetic confounders and for enrolling centre, was protective against severity of steatosis (GG vs CC OR 0.77, 95% CI 0.62-0.95; P=.01), steatohepatitis (GG vs CC OR 0.62, 95% CI 0.47-0.83; P=.001) and severity of fibrosis (GG vs CC OR 0.83, 95% CI 0.67-0.98; P=.04). The C allele was associated with higher total circulating cholesterol (P=.01). Patients carrying the NR1H4 rs35724 C allele had significantly higher hepatic mRNA levels of FXR and were associated with higher hepatic FGFR4 and Cyp39A1 that are in turn involved in bile acid synthesis.Increased hepatic FXR expression due to the NR1H4 rs35724 C allele is linked to higher serum cholesterol but protects against steatosis, steatohepatitis and liver fibrosis. The translational relevance of these results for patient risk stratification and FXR-targeted therapy warrants further investigation.

-
In: Liver international (Print). - : Wiley-Blackwell Publishing Inc.. - 1478-3223 .- 1478-3231. ; 41:11, s. 2693-2702

Research review (peer-reviewed)abstract
- BACKGROUND: Previous studies investigating the prevalence of celiac disease (CD) in individuals with autoimmune hepatitis (AIH) have shown highly variable results. We therefore aimed to examine the prevalence of CD in individuals with AIH.METHODS: Two professional librarians searched PubMed, EMBASE, Cochrane and Web of Science Core Collection up until 7 February 2020. The search terms included 'celiac disease', 'celiac', 'transglutaminases', 'gluten', 'gliadin', 'EMA', 'TTG' and 'villous' combined with 'autoimmune', 'hepatitis', 'ANA', 'SMA' and 'LKM'. This search yielded 2419 unique publications. A systematic review based on the PRISMA guidelines resulted in 31 articles eligible for full text review. Fifteen articles were deemed relevant, with 8 being included in our main analysis. A fixed-effect inverse variance-weighted model was used, and heterogeneity was calculated.RESULTS: Our main analysis included 567 individuals with AIH from eight studies, where biopsy-verified CD (equivalent to Marsh III) was seen in 23 individuals (4.1%). The pooled prevalence of CD in AIH was 3.5% (95% CI = 1.6%-5.3%) (heterogeneity: P = .874; I2 = 0.0%), which is clearly higher than the 1% CD seen in most general populations. When also including studies where CD had been diagnosed through positive serology without biopsy (15 studies: n = 1817 individuals with AIH), the pooled prevalence of CD was 2.9% (95% CI = 2.1%-3.8%) (heterogeneity: P < .001; I2 = 66.8%).CONCLUSION: Our results demonstrate a higher prevalence of CD in individuals with AIH compared to the general population. CD screening may be considered in patients with AIH.

Journal article (peer-reviewed)abstract
- Background & Aims Mutations in the HFE gene can lead to hereditary haemochromatosis (HH) and have been suggested to increase the risk of extra-hepatic diseases, especially breast and colorectal cancer. Here we investigated long-term outcomes of Swedish patients with HFE mutations. Methods We identified 3645 patients with a homozygous p.C282Y (62%) or a compound heterozygous p.C282Y/p.H63D (38%) mutation from eight centres in Sweden between 1997 and 2017. These were matched 1:10 by age, sex and county of residence to reference individuals from the general population. We ascertained incident outcomes until the end of 2017 by linkage to national registers. Studied outcomes were HH, cirrhosis, hepatocellular carcinoma (HCC), breast cancer (in women), colorectal cancer, type 1 and 2 diabetes, hypothyroidism, Parkinson's disease and mortality. Cox proportional hazards regression was used to estimate hazard ratios for these outcomes. Results Median age at diagnosis was 52 years, 44% were females. During a mean follow-up of 7.9 years, we found an increased risk for HCC, HH, cirrhosis, type 2 diabetes, osteoarthritis and death. Excess mortality was only seen in men. No increased risk was seen for colorectal or breast cancer. Liver-related outcomes were rare, with a cumulative incidence of HFE mutation carriers in a university hospital setting had an increased risk for mortality in men, along with increased risks of cirrhosis, HCC, diabetes type 2, and osteoarthritis. In general, the absolute risk for adverse outcomes was low and no increased risk for colon or breast cancer was observed.

- BACKGROUND & AIMS: End-stage liver disease (ESLD) happens due to the development and progression of chronic liver disease. This study aims to investigate the temporal trend, patient characteristics, and outcomes of atrial fibrillation (AF) in hospitalized ESLD patients across the United States.METHODS: Nationwide Inpatient Sample from 2003 to 2014 was utilized to retrospectively study the weighted prevalence of AF in hospitalized ESLD patients. Multivariable regression models were used to assess the association between AF with clinical factors, in-hospital mortality, length of stay (LOS), and cost.RESULTS: 639,345 hospitalizations associated with ESLD were identified, of which 47,710 (7.48%) were diagnosed with AF. The prevalence of AF increased from 5.73% in 2003 to 9.75% in 2014 in ESLD and varied by age, race, income, insurance type, and hospital characteristics. Factors associated with AF included advancing age, male, white race, high income, and urban teaching hospital. AF presence was associated with significant higher in-hospital mortality (odds ratio, 1.40; 95% confidence interval, 1.35-1.45), 21% longer LOS and 22% higher cost. In addition, a significant decreasing trend in in-hospital mortality was observed (from 16.70% to 10.63% in patients with AF and from 10.74% to 7.50% in patients without AF).CONCLUSIONS: The prevalence of AF in hospitalized ESLD patients has continued to increase from 2003 through 2014. AF is associated with poor prognosis and higher health resource utilization. Innovative anticoagulation strategies through improved collaboration between cardiologists and hepatologists are required for better management of hospitalized ESLD patients comorbid with AF.

-
Journal article (peer-reviewed)abstract
- Background & Aims: Liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) is a non-invasive diagnostic biomarker of liver fibrosis. It is uncertain if LSM can predict risk for future liver-related outcomes in large, heterogenous populations. Methods: This Swedish multi-centre cohort study included patients (n = 14 414) from 16 sites who underwent LSM by VCTE between 2008 and 2020. Outcomes were ascertained from national registers. We investigated progression to cirrhosis with portal hypertension or hepatocellular carcinoma (HCC), separately. Cox regression was used to obtain hazard ratios (HRs). Harrel's C-index was used to measure discrimination of VCTE. Results: Included patients had a median age of 46 (interquartile range 34-57), median LSM of 5.9 kPa (4.6-8.0), 59% were male, and the majority had hepatitis C (50.1%). During a median follow-up of 5.9 (4.3-8.0) years, 402 patients (2.7%) developed cirrhosis with portal hypertension. In patients with an LSM >= 25 kPa, 28.7% developed cirrhosis with portal hypertension within 5 years of follow-up, while only .6% of patients with an LSM <10 kPa did. This translated to a HR of 48.3 (95% confidence interval = 37.6-62.0). VCTE had a high discriminative ability, with C-indices above .80 for most liver diseases, including .82 for MASLD. Similar findings were seen for incident HCC. Conclusions: Increased LSM by VCTE was associated with an increased risk of progression to both cirrhosis with portal hypertension, and to HCC, and had a high discriminative ability across different aetiologies of chronic liver diseases. These results support the use of VCTE to guide follow-up and treatment decisions.

Journal article (peer-reviewed)abstract
- Background and Aims Several genotypes associate with a worse histopathological profile in patients with non-alcoholic fatty liver disease (NAFLD). Whether genotypes impact long-term outcomes is unclear. We investigated the importance of PNPLA3, TM6SF2, MBOAT7 and GCKR genotype for the development of severe outcomes in NAFLD. Method DNA samples were collected from 546 patients with NAFLD. Advanced fibrosis was diagnosed by liver biopsy or elastography. Non-alcoholic steatohepatitis (NASH) was histologically defined. Additionally, 5396 controls matched for age, sex and municipality were identified from population-based registers. Events of severe liver disease and all-cause mortality were collected from national registries. Hazard ratios (HRs) adjusted for age, sex, body mass index and type 2 diabetes were estimated with Cox regression. Results In NAFLD, the G/G genotype of PNPLA3 was associated with a higher prevalence of NASH at baseline (odds ratio [OR] 3.67, 95% CI = 1.66-8.08), but not with advanced fibrosis (OR 1.81, 95% CI = 0.79-4.14). After up to 40 years of follow-up, the PNPLA3 G/G genotype was associated with a higher rate of severe liver disease (adjusted hazard ratio [aHR] 2.27, 95% CI = 1.15-4.47) compared with the C/C variant. NAFLD patients developed cirrhosis at a higher rate than controls (aHR 9.00, 95% CI = 6.85-11.83). The PNPLA3 G/G genotype accentuated this rate (aHR 23.32, 95% = CI 9.14-59.47). Overall mortality was not affected by any genetic variant. Conclusion The PNPLA3 G/G genotype is associated with an increased rate of cirrhosis in NAFLD. Our results suggest that assessment of the PNPLA3 genotype is of clinical relevance in patients with NAFLD to individualize monitoring and therapeutic strategies.

Journal article (peer-reviewed)abstract
- Background and Aims: Identifying international differences in utilization and outcomes of liver transplantation (LT) after donation after circulatory death (DCD) donation provides a unique opportunity for benchmarking and population-level insight.Methods: Adult (>= 18 years) LT data between 2008 and 2018 from the UK and US were used to assess mortality and graft failure after DCD LT. We used time-dependent Cox-regression methods to estimate hazard ratios (HR) for risk-adjusted short-term (0-90 days) and longer-term (90 days-5 years) outcomes.Results: One-thousand five-hundred-and-sixty LT receipts from the UK and 3426 from the US were included. Over the study period, the use of DCD livers increased from 15.7% to 23.9% in the UK compared to 5.1% to 7.6% in the US. In the UK, DCD donors were older (UK:51 vs. US:33 years) with longer cold ischaemia time (UK: 437 vs. US: 333 min). Recipients in the US had higher Model for End-stage Liver Disease (MELD) scores, higher body mass index, higher proportions of ascites, encephalopathy, diabetes and previous abdominal surgeries. No difference in the risk-adjusted short-term mortality or graft failure was observed between the countries. In the longer-term (90 days-5 years), the UK had lower mortality and graft failure (adj.mortality HR:UK: 0.63 (95% CI: 0.49-0.80); graft failure HR: UK: 0.72, 95% CI: 0.58-0.91). The cumulative incidence of retransplantation was higher in the UK (5 years: UK: 11.9% vs. 4.6%; p < .001).Conclusions: For those receiving a DCD LT, longer-term post-transplant outcomes in the UK are superior to the US, however, significant differences in recipient illness, graft quality and access to retransplantation were seen between the two countries.

- BACKGROUND AND AIMS: Previous studies have shown suboptimal screening for hepatitis D virus (HDV) among patients with chronic hepatitis B (CHB). This study presents the cascade of care for HDV infection in a major secondary referral centre in Southern Stockholm, Sweden.METHODS: HBsAg+ve patients attending Karolinska University Hospital (KUH) from 1992 to 2022 were identified. The prevalence of anti-HDV and/or HDV RNA positivity, interferon (IFN) therapy and maintained virological responses (MVR) after HDV treatment were assessed. Also, time to anti-HDV testing was analysed in relation to liver-related outcomes with logistic regression.RESULTS: Among 4095 HBsAg+ve persons, 3703 (90.4%) underwent an anti-HDV screening; within a median of 1.8 months (range 0.0-57.1) after CHB diagnosis. This screening rate increased over time, to 97.9% in the last decade. Overall, 310 (8.4%) were anti-HDV+ve, of which 202 (65.2%) were HDV RNA+ve. Eighty-five (42%) received IFN, and 9 (10.6%) achieved MVR at the last follow-up. The predictive factors for anti-HDV screening were Asian origin, diagnosis after the year 2012, HIV co-infection (negative factor) and HBV DNA level < 2000 IU/mL in univariable analysis, while HIV co-infection was the only remaining factor in multivariable analysis. Delayed anti-HDV test >5 years was independently associated with worsened liver-related outcomes (adjusted odds ratio = 7.6, 95% CI 1.8-31.6).CONCLUSION: Higher frequency of HDV screening than previously published data could be seen among CHB patients at KUH in a low-endemic setting. Receiving a delayed screening test seems to be associated with worse outcomes, stressing the need of a strategy for timely HDV diagnosis.

- BackgroundWhile ALPPS triggers a fast liver hypertrophy, it is still unclear which factors matter most to achieve accelerated hypertrophy within a short period of time. The aim of the study was to identify patient-intrinsic factors related to the growth of the future liver remnant (FLR).MethodsThis cohort study is composed of data derived from the International ALPPS Registry from November 2011 and October 2018. We analyse the influence of demographic, tumour type and perioperative data on the growth of the FLR. The volume of the FLR was calculated in millilitre and percentage using computed-tomography (CT) scans before and after stage 1, both according to Vauthey formula.ResultsA total of 734 patients were included from 99 centres. The median sFLR at stage 1 and stage 2 was 0.23 (IQR, 0.18–0.28) and 0.39 (IQR: 0.31–0.46), respectively. The variables associated with a lower increase from sFLR1 to sFLR2 were age˃68 years (p = .02), height ˃1.76 m (p ˂ .01), weight ˃83 kg (p ˂ .01), BMI˃28 (p ˂ .01), male gender (p ˂ .01), antihypertensive therapy (p ˂ .01), operation time ˃370 minutes (p ˂ .01) and hospital stay˃14 days (p ˂ .01). The time required to reach sufficient volume for stage 2, male gender accounts 40.3% in group ˂7 days, compared with 50% of female, and female present 15.3% in group ˃14 days compared with 20.6% of male.ConclusionsHeight, weight, FLR size and gender could be the variables that most constantly influence both daily growths, the interstage increase and the standardized FLR before the second stage.
