Summary Background There are limited data regarding the longitudinal association between MEFIB‐Index (MRE combined with FIB‐4) versus MAST‐Score (MRI‐aspartate aminotransferase) and hepatic decompensation. Aim To examine the longitudinal association between MEFIB‐Index versus MAST‐Score in predicting hepatic decompensation in patients with metabolic dysfunction‐associated steatotic liver disease (MASLD). Methods This was a longitudinal, retrospective analysis of subjects from United States, Japan, and Turkey who underwent a baseline MRE and MRI‐PDFF and were followed for hepatic decompensation. Cox‐proportional hazard analyses were used to assess the association between MEFIB‐Index versus MAST‐Score with a composite primary outcome (hepatic decompensation) defined as ascites, hepatic encephalopathy, and varices needing treatment. Results This meta‐analysis of individual participants (IPDMA) included 454 patients (58% women) with a mean (±SD) age of 56.0 (±13.5) years. The MEFIB‐Index (MRE ≥3.3 kPa + FIB 4 ≥1.6) and MAST‐Score (>0.242) were positive for 34% and 9% of the sample, respectively. At baseline, 23 patients met criteria for hepatic decompensation. Among 297 patients with available longitudinal data with a median (IQR) of 4.2 (5.0) years of follow‐up, 25 incident cases met criteria for hepatic decompensation. A positive MEFIB‐Index [HR = 49.22 (95% CI: 6.23–388.64, p < 0.001)] and a positive MAST‐Score [HR = 3.86 (95% CI: 1.46–10.17, p < 0.001)] were statistically significant predictors of the incident hepatic decompensation. MEFIB‐Index ( c ‐statistic: 0.89, standard error (SE) = 0.02) was statistically superior to the MAST‐Score ( c ‐statistic: 0.81, SE = 0.03) ( p < 0.0001) in predicting hepatic decompensation. Conclusion A combination of MRI‐based biomarker and blood tests, MEFIB‐Index and MAST‐Score can predict the risk of hepatic decompensation in patients with MASLD.

SummaryObjectiveStudies of dehydroepiandrosterone (DHEA) therapy in older adults suggest sex‐specific effects on bone mineral density (BMD) and body composition, but the ability of a single study to reach this conclusion was limited. We evaluated the effects of DHEA on sex hormones, BMD, fat mass and fat‐free mass in older women and men enrolled in four similar clinical trials.DesignPooled analyses of data from four double‐blinded, randomized controlled trials.ParticipantsWomen (n = 295) and men (n = 290) aged 55 years or older who took DHEA or placebo tablet daily for 12 months.MeasurementsTwelve‐month changes in BMD, fat mass, fat‐free mass and serum DHEA sulphate (DHEAS), (17)estradiol, testosterone and insulin‐like growth factor‐1 (IGF‐1).ResultsWomen on DHEA had increases (mean ± SD; all P < 0.001 vs placebo) in DHEAS (231 ± 164 µg/dL), testosterone (18.6 ± 20.9 µg/dL), (17)estradiol (8.7 ± 11.0 pg/mL) and IGF‐1 (25.1 ± 52.3 ng/mL), and men had increases in DHEAS (269.0 ± 177 µg/dL; P < 0.01), (17)estradiol (4.8 ± 12.2 pg/m; P < 0.01) and IGF‐1 (6.3 ± 41.4 ng/mL; P < 0.05). Women on DHEA had increases in lumbar spine (1.0% ± 3.4%) and trochanter (0.5% ± 3.8%) BMD and maintained total hip BMD (0.0% ± 2.8%); men had no BMD benefit and a decrease in fat mass (−0.4 ± 2.6 kg; all P < 0.01 vs placebo).ConclusionsDehydroepiandrosterone therapy may be an effective approach for preserving bone and muscle mass in women. Key questions are (a) the extent to which longer duration DHEA can attenuate the loss of bone and muscle in women, and (b) whether DHEA has a more favourable benefit‐to‐risk profile for women than oestrogen therapy.
