RESUMO

BACKGROUND AND AIM: Telehealth interventions may improve access to care, disease-specific, and quality outcomes in chronic liver diseases (CLDs). We aimed to systematically evaluate outcomes of telehealth interventions in CLDs. MATERIALS AND METHODS: We used key terms and searched PubMed/EMBASE from inception to January 10, 2022. Two authors independently screened abstracts. Disagreements were resolved by a third reviewer. We included any type of CLD, including posttransplant patients, and extracted outcomes as defined by authors for each etiology of CLD (sustained virological response in HCV or weight loss in NAFLD). Meta-analysis was not performed because of the heterogeneity of data. Quality assessment was performed using the Newcastle-Ottawa Scale for observational studies and the Cochrane Risk of Bias tool for clinical trials. RESULTS: Of 4250 studies screened, 43 met the inclusion criteria. Of these, 28 reported HCV treatment outcomes. All studies showed no statistically significant differences between sustained virological response rates in TH groups compared with control groups or historic cohorts. Eight studies evaluating liver transplant-related processes and outcomes demonstrated improved rates of transplant evaluation and referrals and decreased short-term readmission rates. Three randomized controlled trials and 1 observational study on NAFLD showed improved weight loss outcomes. One retrospective study showed reduced mortality risk in CLD patients with at least 1 TH encounter. CONCLUSIONS: TH interventions in patients with CLDs consistently show equivalent or improved clinical outcomes compared with traditional encounters. TH in CLDs can bridge the gap in access while maintaining the quality of care for underserved populations.

RESUMO

BACKGROUND: Clinical guidelines reserve endoscopic surveillance after a gastric intestinal metaplasia (GIM) diagnosis for high-risk patients. However, it is unclear how closely guidelines are followed in clinical practice. We examined the effectiveness of a standardized protocol for the management of GIM among gastroenterologists at a US hospital. METHODS: This was a preintervention and postintervention study, which included developing a protocol and education of gastroenterologists on GIM management. For the preintervention study, 50 patients with GIM were randomly selected from a histopathology database at the Houston VA Hospital between January 2016 and December 2019. For the postintervention study, we assessed change in GIM management in a cohort of 50 patients with GIM between April 2020 and January 2021 and surveyed 10 gastroenterologists. The durability of the intervention was assessed in a cohort of 50 GIM patients diagnosed between April 2021 and July 2021. RESULTS: In the preintervention cohort, GIM location was specified (antrum and corpus separated) in 11 patients (22%), and Helicobacter pylori testing was recommended in 11 of 26 patients (42%) without previous testing. Gastric mapping biopsies were recommended in 14% and surveillance endoscopy in 2%. In the postintervention cohort, gastric biopsy location was specified in 45 patients (90%, P <0.001) and H. pylori testing was recommended in 26 of 27 patients without prior testing (96%, P <0.001). Because gastric biopsy location was known in 90% of patients ( P <0.001), gastric mapping was not necessary, and surveillance endoscopy was recommended in 42% ( P <0.001). One year after the intervention, all metrics remained elevated compared with the preintervention cohort. CONCLUSIONS: GIM management guidelines are not consistently followed. A protocol for GIM management and education of gastroenterologists increased adherence to H. pylori testing and GIM surveillance recommendations.

RESUMO

INTRODUCTION: There are limited longitudinal data on the cost of treating patients with cirrhosis, which hampers value-based improvement initiatives. METHODS: We conducted a retrospective cohort study of patients with cirrhosis seen in the Veterans Affairs health care system from 2011 to 2015. Patients were followed up through 2019. We identified a sex-matched and age-matched control cohort without cirrhosis. We estimated incremental annual health care costs attributable to cirrhosis for 4 years overall and in subgroups based on severity (compensated, decompensated), cirrhosis complications (ascites, encephalopathy, varices, hepatocellular cancer, acute kidney injury), and comorbidity (Deyo index). RESULTS: We compared 39,361 patients with cirrhosis with 138,964 controls. The incremental adjusted costs for caring of patients with cirrhosis were $35,029 (95% confidence interval $32,473-$37,585) during the first year and ranged from $14,216 to $17,629 in the subsequent 3 years. Cirrhosis complications accounted for most of these costs. Costs of managing patients with hepatic encephalopathy (year 1 cost, $50,080) or ascites ($50,364) were higher than the costs of managing patients with varices ($20,488) or hepatocellular cancer ($37,639) in the first year. Patients with acute kidney injury or those who had multimorbidity were the most costly at $64,413 and $66,653 in the first year, respectively. DISCUSSION: Patients with cirrhosis had substantially higher health care costs than matched controls and multimorbid patients had even higher costs. Cirrhosis complications accounted for most of the excess cost, so preventing complications has the largest potential for cost saving and could serve as targets for improvement.

RESUMO

BACKGROUND & AIMS: Guidelines recommend hepatocellular carcinoma (HCC) surveillance in patients with chronic HBV infection. Several HCC risk prediction models are available to guide surveillance decisions, but their comparative performance remains unclear. METHODS: Using a retrospective cohort of patients with HBV treated with nucleos(t)ide analogues at 130 Veterans Administration facilities between 9/1/2008 and 12/31/2018, we calculated risk scores from 10 HCC risk prediction models (REACH-B, PAGE-B, m-PAGE-B, CU-HCC, HCC-RESCUE, CAMD, APA-B, REAL-B, AASL-HCC, RWS-HCC). We estimated the models' discrimination and calibration. We calculated HCC incidence in risk categories defined by the reported cut-offs for all models. RESULTS: Of 3,101 patients with HBV (32.2% with cirrhosis), 47.0% were treated with entecavir, 40.6% tenofovir, and 12.4% received both. During a median follow-up of 4.5 years, 113 patients developed HCC at an incidence of 0.75/100 person-years. AUC values for 3-year HCC risk were the highest for RWS-HCC, APA-B, REAL-B, and AASL-HCC (all >0.80). Of these, 3 (APA-B, RWS-HCC, REAL-B) incorporated alpha-fetoprotein. AUC values for the other models ranged from 0.73 for PAGE-B to 0.79 for CAMD and HCC-RESCUE. Of the 7 models with AUC >0.75, only APA-B was poorly calibrated. In total, 10-20% of the cohort was deemed low-risk based on the published cut-offs. None of the patients in the low-risk groups defined by PAGE-B, m-PAGE-B, AASL-HCC, and REAL-B developed HCC during the study timeframe. CONCLUSION: In this national cohort of US-based patients with HBV on antiviral treatment, most models performed well in predicting HCC risk. A low-risk group, in which no cases of HCC occurred within a 3-year timeframe, was identified by several models (PAGE-B, m-PAGE-B, CAMD, AASL-HCC, REAL-B). Further studies are warranted to examine whether these patients could be excluded from HCC surveillance. LAY SUMMARY: Risk prediction models for hepatocellular carcinoma (HCC) in patients infected with hepatitis B virus (HBV) could guide HCC surveillance decisions. In this large cohort of US-based patients receiving treatment for HBV, most published models discriminated between those who did or did not develop HCC, although the RWS-HCC, REAL-B, and AASL-HCC performed the best. If confirmed in future studies, these models could help identify a low-risk subset of patients on antiviral treatment who could be excluded from HCC surveillance.

RESUMO

BACKGROUND & AIMS: There is controversy regarding the benefits of direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) infection for patients with a history of hepatocellular carcinoma (HCC). We performed a multicenter cohort study to compare overall survival between patients with HCV infection treated with DAAs and patients who did not receive DAA treatment for their HCV infection after complete response to prior HCC therapy. METHODS: We conducted a retrospective cohort study of patients with HCV-related HCC who achieved a complete response to resection, local ablation, transarterial chemo- or radioembolization, or radiation therapy, from January 2013 through December 2017 at 31 health care systems throughout the United States and Canada. We used Cox proportional hazards regression to determine the association between receipt of DAA therapy, modeled as a time-varying covariate, and all-cause mortality, accounting for informative censoring and confounding using inverse probability weighting. RESULTS: Of 797 patients with HCV-related HCC, 383 (48.1%) received DAA therapy and 414 (51.9%) did not receive treatment for their HCV infection after complete response to prior HCC therapy. Among DAA-treated patients, 43 deaths occurred during 941 person-years of follow-up, compared with 103 deaths during 526.6 person-years of follow-up among patients who did not receive DAA therapy (crude rate ratio, 0.23; 95% confidence interval [CI], 0.16-0.33). In inverse probability-weighted analyses, DAA therapy was associated with a significant reduction in risk of death (hazard ratio, 0.54; 95% CI, 0.33-0.90). This association differed by sustained virologic response to DAA therapy; risk of death was reduced in patients with sustained virologic response to DAA therapy (hazard ratio, 0.29; 95% CI, 0.18-0.47), but not in patients without a sustained virologic response (hazard ratio, 1.13; 95% CI, 0.55-2.33). CONCLUSIONS: In an analysis of nearly 800 patients with complete response to HCC treatment, DAA therapy was associated with a significant reduction in risk of death.

RESUMO

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

RESUMO

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

RESUMO

In the United States, centers performing liver transplant (LT) are primarily evaluated by patient survival within 1 year after LT, but tight clustering of outcomes allows only a narrow window for evaluation of center variation for quality improvement. Alternate measures more relevant to patients and the transplant community are needed. We examined adults listed for LT in the United States, using data submitted to the Scientific Registry of Transplant Recipients. Intention-to-treat (ITT) survival was defined as survival within 1 year from listing, regardless of transplant. Mixed effects/frailty models were used to assess center variation in ITT survival. Between January 2010 and December 2016, there were 66,428 new listings at 113 centers. Overall, median 1-year ITT survival was 79.8% (interquartile range [IQR], 76.1%-83.4%), whereas 1-year waiting-list (WL) survival was 75.8% (IQR, 71.2%-79.4%), and 1-year post-LT survival was 90.0% (IQR, 87.9%-91.8%). Higher rates of ITT mortality were correlated with increased WL mortality (correlation, r = 0.76), increased post-LT mortality (r = 0.31), lower volume centers (r = -0.34), and lower transplant rate ratio (r = -0.25). Similar patterns were observed in the subgroup of WL candidates listed with Model for End-Stage Liver Disease (MELD) ≥25: median 1-year ITT survival was 65.2% (IQR, 60.2%-72.6%), whereas 1-year post-LT survival was 87.5% (IQR, 84.0%-90.9%), and 1-year WL survival was 36.6% (IQR, 27.9%-47.0%). In mixed effects modeling, the transplant center was an independent predictor of ITT survival even after adjustment for age, sex, MELD, and sociodemographic variables. Center variation for ITT survival was larger compared with post-LT survival. The measurement of ITT outcome offers a complementary method to assess center performance. This is a first step toward understanding differences in program quality beyond patient and graft survival after LT.

RESUMO

Health care delivery is increasingly evaluated according to quality measures, yet such measures are underdeveloped for cirrhosis. The Practice Metrics Committee of the American Association for the Study of Liver Diseases was charged with developing explicit process-based and outcome-based measures for adults with cirrhosis. We identified candidate measures from comprehensive reviews of the literature and input from expert clinicians and patient focus groups. We conducted an 11-member expert clinician panel and used a modified Delphi method to systematically identify a set of quality measures in cirrhosis. Among 119 candidate measures, 46 were identified as important measures to define the quality of cirrhosis care, including 26 process measures, 7 clinical outcome measures, and 13 patient-reported outcome measures. The final process measures captured care processes for ascites (n = 5), varices/bleeding (n = 7), hepatic encephalopathy (n = 4), hepatocellular cancer (HCC) screening (n = 1), liver transplantation evaluation (n = 2), and other care (n = 7). Clinical outcome measures included survival, variceal bleeding and rebleeding, early-stage HCC, liver-related hospitalization, and rehospitalization within 7 and 30 days. Patient-reported outcome measures covered physical symptoms, physical function, mental health, general function, cognition, social life, and satisfaction with care. The final list of patient-reported outcomes was validated in 79 patients with cirrhosis from nine institutions in the United States. Conclusion: We developed an explicit set of evidence-based quality measures for adult patients with cirrhosis. These measures are a tool for providers and institutions to evaluate their care quality, drive quality improvement, and deliver high-value cirrhosis care. The quality measures are intended to be applicable in any clinical care setting in which care for patients with cirrhosis is provided.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) commonly coexists with Crohn's disease (CD); however, it remains unclear if it is more prevalent than would be expected as ultrasound surveys of CD patients report a very wide range of prevalence (9%-40%).1-3 To address this uncertainty, we performed a prospective, cross-sectional survey of NAFLD in CD patients by generating magnetic resonance proton density fat fraction (MR-PDFF) maps as compared with 2 control populations. MR-PDFF provides a quantitative, sensitive and specific (97% and 100%, respectively) radiographic surrogate for liver fat.4.

RESUMO

Patients with cirrhosis seek improvement in their symptoms, functioning, quality of life, and satisfaction with the care they receive. However, these patient-reported outcomes (PROs) are not routinely measured for clinical care, research, or quality improvement. The members of the American Association for the Study of Liver Diseases Practice Metrics Committee, charged with developing quality indicators for clinical practice, performed a scoping review of PROs in cirrhosis. The aim is to synthesize a comprehensive set of PROs for inclusion into a standard patient-centered outcome set. We searched Medline, Embase, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and the Cochrane Trial Library since inception, with final searches run between April 20 and June 1, 2017. Studies were included if they reported the construction and/or validation of a PRO instrument for patients with cirrhosis or if they assessed the clinical (case-mix) variables determining responses to established PRO scales. Eleven studies were selected that yielded 259 items specific to patients with cirrhosis. After removing duplicates, 152 unique items were isolated. These items were consolidated into seven domains: physical symptoms, physical function, mental health, general function, cognition, social life, and satisfaction with care. The seven domains included 52 subdomains (e.g., physical domain, abdominal pain subdomain). Twelve variables were identified that independently modified established PRO scales. These included clinical factors (severity of liver disease and its complications, medication burden, and comorbidities), specific PROs (cramps, pruritis), and surrogate outcome measures (falls, hospitalization). CONCLUSION: This scoping review identified and categorized a large existing set of PRO concepts that matter to patients with cirrhosis; these outcomes may now be translated into usable measures both for the assessment of the quality of cirrhosis care in clinical practice and to perform research from the patient's perspective.

RESUMO

In 2006, derivation of the donor risk index (DRI) highlighted the importance of donor factors for successful liver transplantation. Over the last decade, the DRI has served as a useful metric of donor quality and has enhanced our understanding of donor factors and their impact upon recipients with hepatitis C virus, those with low Model for End-Stage Liver Disease (MELD) score, and individuals undergoing retransplantation. DRI has provided the transplant community with a common language for describing donor organ characteristics and has served as the foundation for several tools for organ risk assessment. It is a useful tool in assessing the interactions of donor factors with recipient factors and their impact on posttransplant outcomes. However, limitations of statistical modeling, choice of donor factors, exclusion of unaccounted donor and geographic factors, and the changing face of the liver transplant recipient have tempered its widespread use. In addition, the DRI was derived from data before the MELD era but is currently being applied to expand the donor pool while concurrently meeting the demands of a dynamic allocation system. A decade after its introduction, DRI remains relevant but may benefit from being updated to provide guidance in the use of extended criteria donors by accounting for the impact of geography and unmeasured donor characteristics. DRI could be better adapted for recipients with nonalcoholic fatty liver disease by examining and including recipient factors unique to this population.

RESUMO

Elastography techniques, such as two-dimensional magnetic resonance elastography (2D-MRE) are increasingly used for the non-invasive assessment of liver fibrosis in patients with nonalchoholic fatty liver disease (NAFLD). Loomba et al. demonstrate that 3D-MRE (shear wave frequency 40 Hz) had even greater diagnostic accuracy than the commercially available 2D-MRE (shear wave frequency 60 Hz) in diagnosing advanced fibrosis (area under the receiver operator curve, AUROC 0.981 vs. 0.921, P<0. 05) using liver biopsy as reference standard. Despite limitations, MRE serves as an important tool in risk stratification for patients with NAFLD.

RESUMO

BACKGROUND: Both obesity and inflammatory bowel disease (IBD) are highly prevalent in Western societies. IBD, including Crohn's disease (CD) and ulcerative colitis (UC), has been historically associated with cachexia and malnutrition. It is uncertain how obesity, a chronic pro-inflammatory state, may impact the course of IBD. AIM: The aim of this study was to report the prevalence of obesity in patients with IBD in a metropolitan US population and to assess the impact of obesity on disease phenotypes, treatment, and surgical outcomes in IBD patients. METHODS: We reviewed the medical records of patients identified from the IBD registries of the Dallas Veterans Affairs Medical Center and Parkland Health and Hospital Systems who were seen from January 1, 2000, to December 31, 2012. RESULTS: Of 581 identified IBD patients, 32.7 % were obese (BMI ≥ 30) and 67.6 % were non-obese (BMI < 30). There were 297 (51.1 %) patients with CD and 284 (48.9 %) patients with UC. The rate of obesity was 30.3 % among CD patients and 35.2 % among UC patients. Overall, obese patients were significantly less likely to receive anti-TNF treatment, undergo surgery, or experience a hospitalization for their IBD than their non-obese counterparts (55.8 vs. 72.1 %, p = .0001). CONCLUSION: Obesity is highly prevalent in our IBD patients, paralleling the obesity rates in the US population. Clinical outcomes were significantly different in obese versus non-obese patients with IBD. Despite the plausible mechanisms whereby obesity might exacerbate IBD, we have found that obesity (as defined by BMI) is a marker of a less severe disease course in IBD.

RESUMO

PURPOSE OF REVIEW: Primary biliary cirrhosis (PBC) was first described in the 1950s as a clinical syndrome of progressive cholestatic liver disease resulting from chronic inflammatory destruction of the intrahepatic bile ducts. In the 1980s, the autoimmune nature of the disease was appreciated with the discovery of disease-specific loss of immune tolerance to the pyruvate dehydrogenase complex and subsequent development of antimitochondrial antibodies and autoreactive T cells. Then, in the 1990s, multiple clinical trials demonstrating the efficacy of ursodiol as a treatment for PBC were published, although it has been clear that ursodiol is not a cure and only delays progression in some patients. RECENT FINDINGS: The study of PBC in the 2000s has been buoyed by two basic science advances: rapid sequencing technologies that have led to genome wide association studies, and elucidation of the role of nuclear hormone receptors in the regulation of bile salt metabolism, which has led to novel therapies under study for cholestatic diseases. SUMMARY: Today's clinician should be able to determine which patients with PBC are likely to progress despite treatment with ursodiol and understand the putative new bile acid and immunosuppressant treatment strategies under development, as well as be aware of the recently described genetic factors at play in the development of PBC.

RESUMO

BACKGROUND: Cardiovascular disease commonly affects advanced liver disease patients. They undergo cardiac interventions to improve cardiac outcomes. Cirrhosis increases complication risk, including bleeding, renal and respiratory failure, and further decompensation, including death, posing a clinical dilemma to proceduralists. Predicting outcomes is crucial in managing patients with cirrhosis. Our aim was to systematically review clinical parameters to assess the mortality and complication risk in patients with cirrhosis undergoing cardiac interventions. METHODS: We searched cirrhosis and cardiovascular intervention terminology in PubMed and Excerpta Medica Database (EMBASE) from inception to January 8, 2023. We included studies reporting clinical scores (e.g. Model for End-stage Liver Disease (MELD), Child-Pugh-Turcotte (CPT), cardiovascular interventions, mortality, and morbidity outcomes). We independently abstracted data from eligible studies and performed qualitative summaries. RESULTS: Eight studies met the inclusion criteria. Procedures included tricuspid valve surgery, catheterization-related procedures, aortic valve replacement (AVR), pericardiectomy, and left ventricular assist device (LVAD) placement. MELD primarily predicted mortality (n = 4), followed by CPT (n = 2). Mortality is significantly increased for MELD > 15 after tricuspid valve surgery. Albumin, creatinine, and MELD were significantly associated with increased mortality after transcatheter AVR (TAVR), although specific values lacked stratification. CPT was significantly associated with increased mortality after cardiac catheterization or pericardiectomy. In LVAD placement, increasing MELD increased the unadjusted odds for perioperative mortality. CONCLUSIONS: Our systematic review showed that clinical parameters predict mortality and morbidity risk in patients with cirrhosis undergoing cardiac procedures.

RESUMO

BACKGROUND: Given the success of direct-acting antivirals (DAAs) in treating hepatitis C (HCV), interest is growing in utilizing solid organs from allografts with active HCV to expand donor availability. AIM: To review post-transplant outcomes and patient survival in HCV-negative recipients receiving solid organ transplants (SOT) from viraemic, that is, HCV+/NAT+ (nucleic acid testing) allografts. METHODS: A literature search was conducted on PubMed and EMBASE from 01/01/2007 to 4/17/2021 for articles matching eligibility criteria. Two authors independently screened titles and abstracts. Disagreements were solved by a third independent reviewer. Methodological quality assessment was done using a modified Newcastle-Ottawa scale (NOS). Data synthesis was done qualitatively using median, ranges and percentages. RESULTS: Thirty-five studies were included (or 852 SOTs): 343 kidney, 233 heart, 204 liver, and 72 lung transplants from viraemic allografts. Of the recipients eligible for sustained virological response at 12 weeks (SVR12) calculation, 100% achieved cure from HCV. No deaths/graft failures were reported to be related to HCV transmission. Seven SOT recipients had viral relapse, with all seven patients treated successfully. Four patients developed fibrosing cholestatic hepatitis with complete resolution post-treatment. CONCLUSIONS: Transplanting viraemic organs into uninfected individuals can become the standard of care for patients who do not have contraindications to DAAs.

RESUMO

BACKGROUND: Crohn's disease (CD) patients have more than double the risk of nonalcoholic fatty liver disease (NAFLD) compared with the general population after considering traditional risk factors. NAFLD remains underappreciated because routine imaging and liver biochemistries are neither sensitive nor specific for the diagnosis. Here we developed a Clinical Prediction Tool for NAFLD in CD (CPN-CD) using readily accessible parameters to diagnose NAFLD, as determined by magnetic resonance proton density fat fraction (PDFF). METHODS: A total of 311 consecutive CD patients who underwent magnetic resonance enterography from June 1, 2017, to May 31, 2018, were screened for NAFLD, defined as a PDFF >5.5% after excluding other liver diagnoses. CPN-CD was derived using binary multivariate logistic regression and internally validated with a 10-fold cross-validation. CPN-CD was compared with the Hepatic Steatosis Index (HSI) by the C-statistic and categorical Net Reclassification Improvement (NRI). RESULTS: CPN-CD included age, sex, ethnicity/race, serum alanine aminotransferase, body mass index, known cardiometabolic diagnoses, CD duration, and current use of azathioprine/6-mercaptopurine. At <20% risk, NAFLD could be excluded with a sensitivity of 86% (negative predictive value, 86%). At ≥50% risk, NAFLD was diagnosed with a specificity of 87% (positive predictive value, 75%). CPN-CD exhibited good discrimination (C-statistic 0.85) compared with fair discrimination of the HSI (C-statistic, 0.76). CPN-CD was superior to the HSI by net reclassification improvement (+0.20; P < 0.001) and decision curve analysis. CONCLUSIONS: CPN-CD outperforms HSI in detecting NAFLD in patients with CD. Future directions include external validation, outcome validation, and testing generalizability to patients with ulcerative colitis.
