Perhaps you could consider the high-density lipoprotein cholesterol ratio (MHR) as a NAFLD novel inflammatory biomarker.

If you are looking for novel biomarkers and have some clinical samples available, you could use proteomics approach. One of the is what Sengenics offers, a discovery platform to screen for autoantibodies to ~1800 antigens involved in rheumatology & infectious diseases, oncology, neurology and endocrinology. Feel free to email me directly if you would like to learn more - [email protected]
There are other technologies for novel biomarker discovery within proteomics, such as Olink - for protein measurements. I hope this helps.
