Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are part of a growing health burden across the globe with disparate rates and outcomes between ethnic groups within the United States. While these disparities have been presented in the context of specific geographic sub-regions of the United States, no comparison has been made to determine whether these effects are truly geographically limited within the United States via a large cohort study.
To determine if disparities in outcomes associated with MASLD/MASH in Hispanic patient populations were geographically determined or if consistent amongst a United States national cohort of patients.
Given the inclusion of University of Texas Medical Branch (UTMB) within the well-studied Southeast Texas sub-region and the disparity of outcomes experienced by Hispanic patients within this region, we set out to determine if this effect was comparable in the wider United States cohort available through the TriNetX platform.
Data collection was performed exclusively through the TriNetX database system, a global federated healthcare research network with formation of two cohorts, a UTMB-only cohort and a United States national cohort. Selection was made for those diagnosed with MASH and further subdivided into those who identified as Hispanic vs non-Hispanic.
Disparities are seen in outcomes such as rates of liver fibrosis/cirrhosis, incidence of hepatocellular carcinoma, all-cause mortality, and rates of type 2 diabetes mellitus (T2DM) within the national and UTMB Hispanic cohorts when compared to the non-Hispanic cohorts, while all-cause mortality in the US cohort was lower in Hispanic/Latino patients and . all-cause mortality within the UTMB cohort was not statistically significant.
Hispanic patients do have disparity of outcomes associated with MASLD/MASH, especially in connection with rates of T2DM. This disparity is not limited to a single geographic location, like Southeast Texas, but is observed in the United States national population cohort also.
Next step, we will investigate whether cardiometabolic criteria or risk factors as listed in the 2023 American Association for the Study of Liver Diseases guidelines occur with greater frequency in the Southeast Texas Hispanic population in comparison to other ethnic groups and whether this offers a possible explanation for the disparity in outcomes observed in similar studies.
