Prediction of Esophageal Varices by Liver Stiffness and Platelets in Persons With Human Immunodeficiency Virus Infection and Compensated Advanced Chronic Liver Disease.

BACKGROUND: People living with human immunodeficiency virus (PLWH) are at increased risk of cirrhosis and esophageal varices. Baveno VI criteria, based on liver stiffness measurement (LSM) and platelet count, have been proposed to avoid unnecessary esophagogastroduodenoscopy (EGD) screening for esophageal varices needing treatment (EVNT). This approach has not been validated in PLWH. METHODS: PLWH from 8 prospective cohorts were included if they fulfilled the following criteria: (1) compensated advanced chronic liver disease (LSM >10 kPa); (2) availability of EGD within 6 months of reliable LSM. Baveno VI (LSM <20 kPa and platelets >150 000/µL), expanded Baveno VI (LSM <25 kPa and platelets >110 000/µL), and Estudio de las Hepatitis Víricas (HEPAVIR) criteria (LSM <21 kPa) were applied to identify patients not requiring EGD screening. Criteria optimization was based on the percentage of EGDs spared, while keeping the risk of missing EVNT <5%. RESULTS: Five hundred seven PLWH were divided into a training (n = 318) and a validation set (n = 189). EVNT were found in 7.5%. In the training set, Baveno VI, expanded Baveno VI, and HEPAVIR criteria spared 10.1%, 25.5%, and 28% of EGDs, while missing 0%, 1.2%, and 2.2% of EVNT, respectively. The best thresholds to rule out EVNT were platelets >110 000/µL and LSM <30 kPa (HIV cirrhosis criteria), with 34.6% of EGDs spared and 0% EVNT missed. In the validation set, HEPAVIR and HIV cirrhosis criteria spared 54% and 48.7% of EGDs, while missing 4.9% and 2.2% EVNT, respectively. CONCLUSIONS: Baveno VI criteria can be extended to HEPAVIR and HIV cirrhosis criteria while sparing a significant number of EGDs, thus improving resource utilization for PLWH with compensated advanced chronic liver disease.

Clinical practice guidelines in Wilson disease.

Three guidelines in Wilson disease (WD) have been issued to date: by the American Association for the Study of Liver Diseases (AASLD) in 2003 with revision in 2008, by the European Association for the Study of the Liver (EASL) in 2012, and most recently by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) in 2018. The following review aims to compare and contrast the approach to diagnosis and management of WD outlined in each guidance. Diagnostic criteria for WD are variable, with the AASLD proposing a clinical/biochemical algorithmic approach, while EASL and ESPGHAN favor use of the Leipzig score. Screening of first-degree relatives differs in modality: clinical and genetic testing in AASLD and ESPGHAN, versus genetic testing alone in EASL. There is general consensus regarding treatment of WD, though ESPGHAN favors zinc over chelators in maintenance phase and for asymptomatic patients. Liver transplantation is indicated in cases of acute liver failure (ALF) due to WD, but not primarily for neuropsychiatric disease in all guidelines. EASL and ESPGHAN advocate for use of the revised King's score to guide transplant listing. There are limited recommendations on special circumstances including pregnancy, surgery, and malignancy risk in WD. Though current recommendations address the management of liver disease due to WD, future guidelines may include a more detailed discussion of neurological and psychiatric manifestations of WD.

Screening for Nonalcoholic Fatty Liver Disease in Inflammatory Bowel Diseases: A Cohort Study Using Transient Elastography.

Background: Inflammatory bowel disease (IBD) patients may be at risk for nonalcoholic fatty liver disease (NAFLD) due to chronic inflammation, hepatotoxic drugs, and alteration of the gut microbiota. Prospective data using accurate diagnostic methods are lacking. Methods: We prospectively investigated prevalence and predictors of NAFLD and liver fibrosis by transient elastography (TE) with associated controlled attenuation parameter (CAP) in IBD patients as part of a routine screening program. NAFLD was defined as CAP ≥248 dB/m. Significant liver fibrosis (stage 2 or higher out of 4) was defined as TE measurement ≥7.0 kPa. Predictors of NAFLD and significant liver fibrosis were determined by logistic regression analysis. Results: A total of 384 patients (mean age 42.4 years, 45.0% male, 64.6% with Crohn's disease) with no significant alcohol intake were included. Prevalence of NAFLD and significant liver fibrosis was 32.8% and 12.2%, respectively. Independent predictors of NAFLD were older age (adjusted odds ratio [aOR], 1.45; 95% confidence interval [CI], 1.15-1.82), higher body mass index (BMI; aOR, 1.31; 95% CI, 1.20-1.42) and higher triglycerides (aOR, 1.45; 95% CI, 1.01-2.09). Significant liver fibrosis was independently predicted by older age (aOR, 1.38; 95% CI, 1.12-1.64) and higher BMI (aOR, 1.14; 95% CI, 1.07-1.23). Extrahepatic diseases were more common in IBD patients with NAFLD compared with those without, namely chronic kidney disease (10.3 vs 2.3%; P < 0.001) and cardiovascular diseases (11.3 vs 4.7%; P = 0.02). Conclusions: NAFLD diagnosed by TE with CAP is a frequent comorbidity in IBD patients and is associated with extrahepatic diseases. Noninvasive screening strategies could help early diagnosis and initiation of interventions, including weight loss, correction of dyslipidemia, and linkage to care. 10.1093/ibd/izy200_video1izy200.video15794817619001.
