ResumoA multisociety Delphi consensus statement on new fatty liver disease nomenclatureJournal of HepatologyVol. 79Issue 6PreviewThe principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favour of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria.

They also introduced a set of simple and appropriate "positive" criteria for diagnosing the disease, independent of alcohol intake or other liver diseases. These criteria apply to both adults and children as the disease is a continuum across the lifespan. We were among the other societies and stakeholders that endorsed this proposal for a multitude of reasons,4Shiha G. Alswat K.

A group of experts under the umbrella of three liver societies proposed using the term metabolic dysfunction-associated steatotic liver disease" (MASLD) and adopted diagnostic criteria from the definition of MAFLD.12Rinella M.E. Lazarus J.V. Ratziu V. et al.A multi-society Delphi consensus statement on new fatty liver disease nomenclature.Ann Hepatol. 2023; 101133PubMed Google Scholar As regional leaders, whose utmost priority is our patients, we spent several months analysing the new data and views on this proposal to determine our regional stance on it. Consequently, under the umbrella of the African Middle East Association of Gastroenterology (AMAGE), we, the undersigned, comprising over 100 signatories representing multiple stakeholders and regional key opinion leaders from over 31 countries, have decided to continue using the name MAFLD as an overarching term and its definition for fatty liver diseases associated with metabolic dysregulation as the official terminology in our region. We made this decision based on: 1) Emerging evidence suggesting that MAFLD more accurately reflects the underlying pathogenesis of the disease and is better at identifying those at high risk of disease outcomes than the proposed MASLD criteria. At a minimum, the MASLD criteria did not lead to any significant improvements that can justify the confusion that could be caused by this change.13Chen L. Tao X. Zeng M. Mi Y. Xu L. Clinical and histological features under different nomenclatures of fatty liver disease: NAFLD, MAFLD, MASLD and MetALD.J Hepatol. 2023; Google Scholar,14Zhao Q. Deng Y. Comparison of mortality outcomes in individuals with MASLD and/or MAFLD.J Hepatol. 2023; Abstract Full Text Full Text PDF Scopus (7) Google Scholar Additionally, numerous studies have demonstrated that the MASLD criteria lack granularity and specificity15Tanaka M. Mori K. Takahashi S. et al.Metabolic dysfunction–associated fatty liver disease predicts new onset of chronic kidney disease better than fatty liver or nonalcoholic fatty liver disease.Nephrol Dial Transplant. 2023; 38: 700-711Crossref PubMed Scopus (20) Google Scholar,16Anirvan P. Khatua C.R. Panigrahi M.K. Singh S.P. Definition of metabolic dysfunction: shifting goalposts.J Clin Exp Hepatol. 2023; Google Scholar. Therefore, the MAFLD definition is the only one that maintains the right balance between sensitivity and specificity. This finding is expected to have significant implications for health policy and cost-effective analysis. 2) The proposed change from MAFLD to MASLD is based on the argument that the term "fatty" can be stigmatising. However, multiple studies and statements have refuted this claim. This point has been accurately illustrated by liver patients' spokespeople, who have also highlighted that "in some cultures being fat is regarded as a sign of good health".17Shiha G. Korenjak M. Casanovas T. et al.MAFLD 2022: an ELPA/ALPA/EASO-ECPO joint statement on disease stigma.J Hepatol. 2022; 77: 1717-1719Abstract Full Text Full Text PDF PubMed Scopus (12) Google Scholar A recent study also showed that the perception of NAFLD stigma varies significantly among patients, providers, geographic locations, and sub-specialties. Only 8% of patients perceived stigma compared to 38% of doctors.18Younossi Z.M. AlQahtani S.A. Alswat K. et al.Global survey of stigma among physicians and patients with nonalcoholic fatty liver disease.J Hepatol. 2023; Abstract Full Text Full Text PDF Scopus (12) Google Scholar Another study demonstrated that the term "fatty" is not necessarily stigmatising in all cultures.19Méndez-Sánchez N. Pal S.C. Fassio E. Díaz-Ferrer J. Prado-Robles J.A. MAFLD: perceived stigma—a single-center Mexican patient survey.Hepatol Int. 2023; 17: 507-508Crossref PubMed Scopus (6) Google Scholar We point out that "steatotic" and "fatty" have the same translation in the languages spoken in our region. We believe that the findings collectively weaken the argument for changing "fatty" to "steatotic". These findings can be a sufficient basis to avoid any abrupt changes in the nomenclature of fatty liver disease. Studies have shown that the transition to MAFLD has positive implications in increasing disease awareness among patients and healthcare providers. It also increases attention to MAFLD at conferences across countries and health systems.20Fouad Y. Gomaa A. Semida N. Ghany W.A. Attia D.

Abdel Salam S. AbdAllah M. Attia D. The change from NAFLD to MAFLD expands fatty liver information flow.Hepatol Res. 2022; 52: 488-489Crossref PubMed Scopus (2) Google Scholar In conclusion, after considering the proposal for a new definition of fatty liver disease, the experts from the Middle East and North Africa, as well as Sub-Saharan Africa, have decided not to endorse the proposed definition. They have instead opted to continue using the existing definition of liver disease (MAFLD) as before. The Asian Pacific Association for the Study of the Liver (APASL) has also taken the same decision. Further studies to confirm the validity of the proposed MASLD definition are needed.
