My last lab came back with an AST/ALT ratio of 1.72. ALT 11, AST 19. Both are normal but Alt has consistently been going down since the start of Methotrexate (Alt- 11, 15, 25, 16, 30), ((Ast-19, 17,1917,22). My labs were otherwise good. I don't drink but had a very slight fatty liver at the start of Methotrexate. I'm on a low protein, low fat vegan elimination diet(Paddison Plan).

Ok, so here's the point. My alt is getting consistently lower and my AST/ALT ratio is getting higher. All info I… read more

ALT specific for liver. AST good. I’m a lab tech. Your values are good.

Thank you so very much! I have worked very hard to tackle this since spring and yes I am very fortunate. I don't take a moment of that for granted. I was in a very bad mental place last spring.

You r lucky your AST and ALT are so low. Ratio is meaningless, especially with normal AST and ALT. If you are still worried check with your PCP. If you are still worried after that check with gastroenterologist.

Your concern about liver health while on methotrexate is valid, especially with a history of fatty liver. Here's some clarification:

Your concern about liver health while on methotrexate is valid, especially with a history of fatty liver. Here's some clarification:

1. AST/ALT Ratio: While an elevated AST/ALT ratio can sometimes indicate liver fibrosis or cirrhosis, it is not diagnostic on its own, especially when both AST and ALT are within normal ranges. Your rheumatologist's approach aligns with standard practice, as isolated changes in the ratio without elevated levels are not typically concerning.

2. Methotrexate and Liver Monitoring: Methotrexate can affect the liver, but serious liver damage is rare with proper monitoring. Regular liver function tests (as you're doing) are key. Persistent abnormalities or significant trends would prompt further investigation, such as imaging (e.g., FibroScan) or additional blood tests.

3. Fatty Liver: Your history of mild fatty liver could contribute to changes in liver enzymes. However, your vegan elimination diet may help improve liver health over time. It's worth discussing whether additional monitoring, like a FibroScan, might provide reassurance.

4. Remission and Methotrexate Reduction: Being in remission is excellent news! Reducing methotrexate under your doctor's guidance is a common step, and it may further reduce any liver-related risks.

5. Discrepancy in Information: Online sources often generalize findings, which can lead to confusion. Your rheumatologist's focus on trends and overall health rather than isolated ratios is a more nuanced approach.

If you're still concerned, consider asking your doctor about non-invasive liver tests like FibroScan or discussing your lab trends in more detail. It's important to feel confident in your care plan.
