Liver enzymes trending down on GLP-1 — anyone have experience?

Posting this because the summary going around does not say what the paper says, and the difference matters for how people here are using it.

The liver data is among the strongest non-weight findings in the class. The semaglutide MASH programme reported a large advantage over placebo on MASH resolution, with a substantial minority also achieving fibrosis improvement — and fibrosis is the endpoint that predicts outcomes. Mechanistically it is reduced hepatic lipogenesis, increased fatty-acid oxidation, less hepatic inflammation, and possibly a direct effect on stellate-cell activation.

Where I think it is weakest: the comparator does most of the work in how this gets reported, and it is not the comparator most people think they are citing.

What I am after is whether normalised enzymes tell you anything about fibrosis, and what the right follow-up measurement is. Happy to be told the question itself is wrong.

Note on sourcing:
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

Liver enzyme update related to liver and MASH: I had mildly elevated ALT/AST at baseline (likely NAFLD). After 9 months on GLP-1 therapy:

MarkerBaselineCurrentNormal Range
ALT72297-56 U/L
AST652510-40 U/L
GGT92379-48 U/L
ALP1128444-147 U/L

FibroScan also improved — liver stiffness from 8.5 kPa to 6.2 kPa. The evidence for GLP-1 agonists in NAFLD/NASH is very promising.

ATTAIN trial (survodutide) context for liver and MASH: survodutide, a GLP-1/glucagon dual agonist, showed -18.7% body weight at 46 weeks in the Phase 3 ATTAIN trial. NASH resolution was achieved in ~60% of patients[1].

This is relevant to liver and MASH because survodutide's glucagon agonism specifically targets hepatic lipid metabolism — making it potentially the best-in-class agent for NASH/MAFLD comorbid with obesity.

Liver imaging follow-up for liver and MASH: FibroScan at baseline showed CAP score 336 dB/m (moderate steatosis) and stiffness 8.8 kPa (possible fibrosis). Diagnosed with NAFLD.

After 10 months: CAP dropped to 229 dB/m (minimal steatosis) and stiffness normalized to 5.7 kPa. Hepatologist says the liver is essentially healing itself as the metabolic stress resolves.

GLP-1 agonists may become first-line NASH therapy. The Phase 3 data on semaglutide for NASH is very promising.

Second this. Posting only so the count is not one.
