FABP1 and metabolic dysfunction-associated steatotic liver disease: Hence, higher plasma FABP1 and stages 3 and 4 of CKD classes in grade 2 or 3 of NAFLD and the positive association between an elevated FABP1 level and creatinine and the negative association with eGFR and albumin in our patients with T2DM may suggest that the higher plasma FABP1 in grade 2 or 3 of NAFLD may be induced by renal dysfunction and elevations in FABP1 level may represent chronic or acute compensatory mechanisms to counteract oxidative stress and inflammation from diabetic nephropathy.
