Endoscopic ultrasound-guided fine needle biopsy using macroscopic on-site evaluation technique reduces the number passes yet maintains a high diagnostic accuracy: A randomized study.

BACKGROUND AND AIM: Although rapid on-site cytological evaluation (ROSE) for endoscopic ultrasound (EUS)-guided tissue acquisition (EUS-TA) may increase diagnostic yield, it is not widely available. Macroscopic on-site evaluation (MOSE) is an alternative modality although it is not standardized for EUS-guided fine-needle biopsy (FNB). We evaluated diagnostic performance of MOSE compared with conventional technique of EUS-TA using core biopsy needle. METHODS: Consecutive patients undergoing EUS-FNA for solid lesions were randomized to MOSE or conventional arms. The primary and secondary outcome measures were diagnostic accuracy, diagnostic yield, sensitivity, specificity, positive and negative predictive values, and the number of passes, respectively. The optimum parameters for macroscopic visible core (MVC, i.e., length, number) by MOSE to achieve accurate diagnosis were evaluated. RESULTS: Ninety-six patients (48 conventional and 48 MOSE) were enrolled. Mean lesion size was larger in MOSE arm (32.67 ± 7.22 vs 29.31 ± 6.98 mm, P = 0.023). Diagnostic accuracy (95.8% vs 91.6%), diagnostic yield (97.9% vs 95.8%), procedure duration, and adverse events of the two methods were similar. Median number of passes with MOSE was less (2 vs 3 P = 0.000). Area under the receiver operating characteristic curve showed that with MOSE, obtaining a total MVC length of 11.5 mm had 93.3% sensitivity, and 2.5 MVC cores (each 4 mm) had 86.7% sensitivity for malignancy diagnosis. CONCLUSIONS: EUS-FNB with MOSE, a simple reliable technique, can achieve a high and comparable diagnostic accuracy with lesser number of passes. Obtaining longer length and greater number of MVC increase the sensitivity to diagnose malignancy with MOSE.

Definitive Role of Contrast-enhanced Endoscopic Ultrasound (EUS) in the Diagnosis of Hepatocellular Carcinoma With Non-diagnostic Cross-sectional Imaging: A Case Report.

The diagnosis of hepatocellular carcinoma is usually centered around cross-sectional imaging (CSI) modalities. However, in some instances focal hepatic lesions may be missed on CSI. Endoscopic ultrasound (EUS) has an evolving role in hepatology and have been shown to be useful in diagnosing focal lesions with advantages of tissue acquisition. We report a case hepatitis B-related cirrhosis presenting with acute decompensation, wherein EUS was used to identify HCC and perform tissue acquisition as CSI was non-diagnostic.

Alcoholic Liver Disease/Non-Alcoholic Fatty Liver Disease Index for Classification of Patients with Steatotic Liver Disease.

Background: Steatotic liver disease (SLD) encompasses metabolic dysfunction-associated steatotic liver disease (MASLD) and alcohol-associated liver disease (AALD) at extremes as well as an overlap group termed MASLD with increased alcohol intake (Met-ALD). The Alcoholic Liver Disease/Non-Alcoholic Fatty Liver Disease Index (ANI) was proposed to differentiate ALD from non-alcoholic fatty liver disease (NAFLD). We analysed the performance of the ANI in differentiating within the SLD spectrum. Methods: In a cross-sectional study at a tertiary care center, 202 adults (>18 years) who were prospectively diagnosed with SLD defined by magnetic resonance imaging-proton density fat fraction >6.4% were enrolled. Alcohol consumption (AC) was recorded according to thresholds for significant AC: 140-350 g/week (or 20-50 g/day) for females and 210-420 g/week (or 30-60 g/day) for males. The ANI was calculated, and area under the receiver operating characteristic curve (AUROC) was generated. Results: Of 202 patients (47 years [interquartile range, IQR, 38 to 55], 23.75% females, 77% obese, 42.1% diabetic, 38.1% hypertensive, 28.7% statin use), 40.5% were ever-alcohol consumers; 120 (59%), 50 (24.7%), and 32 (15.8%) were MASLD (ANI, -3.7 [IQR, -7 to -1.6]; Met-ALD, - 1.45 [IQR, -2.4 to 0.28]; and AALD, 0.71 [IQR, -1.3 to 4.8], respectively; P<0.05 for all). The AUROC of the ANI for MASLD and AALD was 0.79 (0.72 to 0.84; cut-off <-3.5) and 0.80 (0.74 to 0.86; cut-off >-1.49), respectively. The ANI outperformed aspartate transaminase/alanine transaminase (AST/ALT) ratio (AUROC=0.75 [0.69 to 0.81]) and gamma glutamyl transpeptidase (GGT) (AUROC=0.74 [0.67 to 0.80]). Addition of GGT did not improve model performance (AUCdiff=0.004; P=0.33). Conclusion: AC is common in MASLD. The ANI distinguishes MASLD and AALD, with individual cut-offs within the intermediate zone indicating Met-ALD. ANI also outperforms AST/ALT ratio or GGT.

Determinants, profile and outcomes of hepatitis A virus-associated severe acute liver injury in adults.

BACKGROUND AND OBJECTIVES: Hepatitis A virus (HAV)-related hepatitis is witnessing an epidemiological transition with increasing trends in adults. While uncomplicated hepatitis remains common, evidence suggests it to be a growing cause for acute liver failure (ALF). In between the two extremes exists severe acute liver injury (s-ALI) which has a propensity to transition to ALF. We aimed at describing the clinical profile of patients with HAV-related s-ALI and identifying potential predictors of progression to ALF. METHODS: This was a single-center retrospective analysis of adult patients admitted with HAV-related s-ALI between April 2022 and December 2023. Demographic and laboratory parameters were compared between patients with only s-ALI and those with ALF. Predictors of progression from s-ALI to ALF were identified using logistic regression. RESULTS: Forty-three patients satisfied criteria of s-ALI, of which 33 (76.7%) had only s-ALI, while 10 (23.3%) had ALF. Patients with s-ALI had lesser leukocytosis (6.3 ± 3 vs. 13.2 ± 4.8), less incidence of acute kidney injury (9.1% vs. 40%) and lower model for end-stage liver disease (MELD) (20 [18-24.5] vs. 31.5 [26-42]), arterial lactate (2.1 [1.3-3.1] vs. 6.3 [5.2-8.0]), arterial ammonia (94 [72-118] vs. 299 [188-573]), procalcitonin (0.5 [0.28-1.25] vs. 3.2 [1.2-6.1]) and ferritin (482 [213-1633] vs. 5186 [1341-11,053]) compared to HAV-ALF (p < 0.05 for all). Three patients (9.09%) with s-ALI progressed to ALF of whom one (3%) died. Baseline ammonia levels (unadjusted odds ratio [OR] 1.03 [1.01-1.06]) and leukocyte count (OR 1.00 [1.00-1.01]) tended to be associated with ALF progression, although none was significant after multi-variable adjustment. Ammonia levels had an area under receiver operating curve of 0.816 (0.64-0.93) (p = 0.009) (cut-off of 144 µmol/L). Additional comorbidities did not impact overall outcomes. CONCLUSION: HAV presents as s-ALI in young adults, with almost one in 10 progressing to ALF. Baseline ammonia may be an important predictor of progression even in s-ALI, but mandates larger well-designed studies.
