    Background: Elevated alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (tBil) may reflect congestion and liver dysfunction in acute heart failure (AHF), while lower ALT also associates with sarcopenia. Objectives: The purpose of this study was to assess ALT, AST, and tBil levels in AHF patients during high-intensity care (HIC) vs usual care (UC) follow-up. Methods: ALT, AST, and tBil were measured 1 to 2 days predischarge in 1,062 AHF patients, and again after 90 days of either HIC or UC according to the STRONG-HF (Safety, Tolerability and efficacy of Rapid Optimization, helped by NT-proBNP testinG, of Heart Failure therapies) protocol. The primary endpoint was 180-day all-cause death or HF hospitalization. Results: Median (Q1-Q3) baseline ALT, AST, and tBil were 21 (15-32) U/L, 23 (17-32) U/L, and 14(10-21) umol/L, respectively. Patients with lower ALT had lower body mass index. Patients with lower ALT, but not tBil or AST, were more likely to have edema, elevated jugular venous pressure, and orthopnea, and use more diuretics prerandomization. A nonsignificant inverse association between ALT and the primary outcome (HR: 0.82 [95% CI: 0.66-1.01] per log-unit, P = 0.06) was observed. Greater reductions of ALT, AST, and tBil to 90 days were associated with greater improvement of edema, rales, NYHA functional class, and N-terminal pro-B-type natriuretic peptide. After 90 days, the HIC group had a greater reduction in AST and tBil than the UC group, while nonsignificant for ALT. The treatment effect of HIC over UC on the primary outcome was consistent across the baseline ALT, AST, and tBil range (all P interaction >0.10), but patients with lower ALT experienced greater health status improvement from HIC. Conclusions: Lower ALT was associated with lower body mass index and more congestion in AHF, supporting previous studies suggesting ALT as a sarcopenia marker. The beneficial effect of HIC on health status was greater in low baseline ALT patients.

    HLA-B*35:01 and Green Tea Induced Liver Injury
    (Wiley, 2021-06) Hoofnagle, Jay H.; Bonkovsky, Herbert L.; Phillips, Elizabeth J.; Li, Yi-Ju; Ahmad, Jawad; Barnhart, Huiman; Durazo, Francisco; Fontana, Robert J.; Gu, Jiezhun; Khan, Ikhlas; Kleiner, David E.; Koh, Christopher; Rockey, Don C.; Seeff, Leonard B.; Serrano, Jose; Stolz, Andrew; Tillmann, Hans L.; Vuppalanchi, Raj; Navarro, Victor J.; Medicine, School of Medicine
    Background and aims: Herbal supplements, and particularly multi-ingredient products, have become increasingly common causes of acute liver injury. Green tea is a frequent component in implicated products, but its role in liver injury is controversial. The aim of this study was to better characterize the clinical features, outcomes, and pathogenesis of green tea-associated liver injury. Approach and results: Among 1,414 patients enrolled in the U.S. Drug-Induced Liver Injury Network who underwent formal causality assessment, 40 cases (3%) were attributed to green tea, 202 to dietary supplements without green tea, and 1,142 to conventional drugs. The clinical features of green tea cases and representation of human leukocyte antigen (HLA) class I and II alleles in cases and control were analyzed in detail. Patients with green tea-associated liver injury ranged in age from 17 to 69 years (median = 40) and developed symptoms 15-448 days (median = 72) after starting the implicated agent. The liver injury was typically hepatocellular (95%) with marked serum aminotransferase elevations and only modest increases in alkaline phosphatase. Most patients were jaundiced (83%) and symptomatic (88%). The course was judged as severe in 14 patients (35%), necessitating liver transplantation in 3 (8%), but rarely resulting in chronic injury (3%). In three instances, injury recurred upon re-exposure to green tea with similar clinical features, but shorter time to onset. HLA typing revealed a high prevalence of HLA-B*35:01, found in 72% (95% confidence interval [CI], 58-87) of green tea cases, but only 15% (95% CI, 10-20) caused by other supplements and 12% (95% CI, 10-14) attributed to drugs, the latter rate being similar to population controls (11%; 95% CI, 10.5-11.5). Conclusions: Green tea-related liver injury has distinctive clinical features and close association with HLA-B*35:01, suggesting that it is idiosyncratic and immune mediated.
