About

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent, underdiagnosed, health system burden and impacts on quality of life including comorbidities in the affected population. Cost-effective strategies focusing on clinical pathways to detect and refer patients to care are needed. The aim of this study is to build a stepwise algorithm combining non-invasive freely available methods (FIB-4, NFS, HFS alone or combined) and vibration-controlled transient elastography (VCTE) in diabetic patients from primary care and endocrinology units.

Full description

NAFLD is a growing health concern and liver fibrosis severity determines its prognosis. The burden of this disease has been estimated in a quarter of the European population and is even higher in diabetic patients, where it raises significantly and can reach up to 80%. The fact that only 10% of these patients will develop significant fibrosis, the strongest predictor of liver-specific morbidity and overall mortality, leads to an overwhelming situation in primary care and endocrine units, where physicians need to screen large numbers of patients to identify individuals with a high risk for developing fibrosis that should be derived to a specialized hepatology unit. New free and accurate non- invasive tests need to be available to be used in primary care and non-hepatologists units to fight against this disappointing situation.

Several non-invasive methods, based on serum and imaging biomarkers, have aimed to identify at-risk patients for NAFLD-related fibrosis, but inconclusive results and many phenotypes that are present or not in patients (diabetes mellitus, obesity and age) reduce their diagnostic accuracy. Current strategies to monitor fibrosis are, therefore, inefficient and often fail to easily distinguish patients with mild disease that can be monitored at primary care from those at risk of advanced fibrosis or cirrhosis that need to receive specialised care and that could benefit from therapeutic interventions, such as participation in clinical trials and liver cancer surveillance programs.

The majority of patients with NAFLD are followed up in the community by general practitioners without definite diagnosis, representing a challenge to identify patients at risk of significant fibrosis who might benefit from an early specific intervention. Accurate fibrosis assessment by primary care or non-hepatologists physicians is limited by a reliance on liver function tests, which correlate poorly with fibrosis, and limited access to discriminatory fibrosis tests. Thus, current management strategies are inefficient in identifying subjects for specialist referral. Patients with mild disease are often referred for NAFLD specialist review when instead the appropriate preventative interventions of lifestyle changes can be delivered effectively in primary care. Conversely, patients with advanced fibrosis or cirrhosis who will benefit from NAFLD specific interventions, including clinical trials and cirrhosis surveillance, often remain undetected until they present with complications of cirrhosis, including hepatocellular carcinoma. This ineffective management contributes to the poor outcomes associated with liver disease and the increasing trends in NAFLD- related morbidity and mortality.

NASH-PI aims to improve the management of NAFLD patients by non-hepatologist physicians through the development of a new specific stepwise NAFLD algorithm following an ETC (Education, tools and communication) process that will be based on:

  1. The development of new care pathways based on different combinations of non-invasive tests that facilitate the derivation of diabetic patients from endocrine and primary care units to specialised liver disease units.
  2. Peer-to-peer sessions with primary care physicians and diabetologists to discuss the techniques and methods available to screen and detect diabetic patients at risk of developing NAFLD-related significant fibrosis.
  3. The implementation of easy and ready to use tools, like an automatic calculation of fNITs in central labs, to allow non-hepatologist physicians detect more efficiently diabetic patients at risk of significant fibrosis.

This proposal will focus on diabetic patients to test the feasibility and accuracy of these diagnostic strategies in a close circuit from primary care and diabetic clinics to NAFLD specialized Units (NSU). Our main goal is to create a NAFLD continuum of care that improves the selection of patients with fibrosis and cirrhosis for referral to secondary care, reducing unnecessary referrals, enhancing the use of healthcare resources with immediate cost-savings, and improving patient experiences by avoiding unnecessary clinic appointments and tests. NASH-PI will improve the identification of NAFLD in diabetic patients to allow for management according to current standard of care and impact on the disease course, helping to reduce NAFLD-related morbidity and mortality and delivering more efficient patient-centered care.

536 participants in 3 patient groups

Arm A: Current management of NAFLD patients in daily clinical practice
Experimental group
Description:
It will be taken as a reference for comparisons and will include the diagnosis and referral criteria that have been used the two previous years. CONSTANTS, a study included in the EPOS European Project has already allowed us to approach the burden of this entity in clinical practice in two sites of this consortium (Mainz and Sevilla). An overall analysis will be conducted to harmonize current standard of care (Arm A) in our centres. The case records of all patients referred with a diagnosis of NAFLD will be reviewed and evaluated for evidence of advanced fibrosis/cirrhosis based on a composite of history, physical examination, imaging, transient elastography, and liver histology when available. HFS, NFS, and FIB-4 scores will be calculated, and patients with a priori low-risk of advanced fibrosis will be deemed to have no evidence of liver fibrosis and thus referred inappropriately.
Treatment:
Diagnostic Test: Derivation algorithms
Arm B: Combination of blood-based non-invasive tests (HFS, NFS, and FIB-4)
Experimental group
Description:
Patients will be assigned with the following scores: 1. 0 points if the value is under the lower cut-off (HFS \<0.12; NFS\<-1.455; FIB-4 \<1.30); 2. 1 point if the value is allocated in the grey zone (HFS 0.12-0.47; NFS -1.455-0.676; FIB-4 1.30-2.67); 3. 2 points if the value is above the higher cut-off (HFS \>0.47; NFS \>0.676; FIB-4 \>2.67). We will determine the optimal cut-offs (between 0 and 6 points) for keeping patients in non-specialized units or referring them to NSUs. * Age corrected threshold should be implemented in patients older than 65 years in NFS (from -1.455 to 0.12) and FIB-4 (from 1.30 to 2.00).
Treatment:
Diagnostic Test: Derivation algorithms
Arm C: Combination of HFS and TE
Experimental group
Description:
Patients will be classified using the blood-based non-invasive tests to determine the HFS and a transient Elastography (TE). Patients with a HFS score of \> 0.12 or TE \>8 kPa for both M and XL probe should be classified as patients with an intermediate-to-high risk of advanced fibrosis and will be referred to a specialist.

Diagnostic Test: Derivation algorithms
