Prevalence, Incidence and Characteristics of NAFLD/NASH in Type 1 Diabetes Mellitus (NAFLDIA1)

3 de marzo de 2022 actualizado por: Christophe De Block, University Hospital, Antwerp

Prevalence, Incidence and Characteristics of NAFLD/NASH in Type 1 Diabetes Mellitus Obtained Via a Non-invasive Screening Protocol

Nonalcoholic fatty liver disease (NAFLD) is a condition characterized by intrahepatic fat accumulation. It is closely related to insulin resistance. To date, it remains unclear whether NAFLD is common in patients with type 1 diabetes or if NAFLD translates into an increased health burden in this population. Screening for NAFLD is challenging due to the limitations of non-invasive diagnostic tools.

Liver biopsy remains the gold standard but is not suited for routine screening or clinical studies. Therefore, there is a great demand for accurate non-invasive screening tools that can not only diagnose but also stage NAFLD. This study aims to generate a large cohort of thoroughly characterized type 1 diabetes patients screened for NAFLD using multiple non-invasive tools including MRI, ultrasound, controlled attenuation parameter, and score panels. We aim to generate a biobank to promote a research collaboration network in the field of non-invasive diagnosis of NAFLD.

A secondary endpoint is to investigate the potential correlation between the presence of NAFLD and the occurrence of micro-or macrovascular complications in patients with diabetes.

Descripción general del estudio

Descripción detallada

This study aims to characterize and follow a thoroughly characterized cohort of adult type 1 diabetes patients free from secondary liver disease due to excessive alcohol usage, viral hepatitis, alfa-1 antitrypsin deficiency, Wilson's disease or steatogenic or hepatotoxic drug use.

The investigators will screen for NAFLD and fibrosis using multiple non-invasive techniques including

  • ultrasound
  • controlled attenuation parameter
  • fatty liver index
  • human steatosis index
  • transient elastography
  • FIB-4
  • NAFLD fibrosis score
  • NASH algorithm based on multiple parameters

Subjects will be screened for microvascular and microvascular complications with:

  • ECG
  • microfilament examination
  • 24hour urine collection for microalbuminuria
  • serum kidney test (creatinine, eGFR)
  • fundoscopy
  • peripheral arterial pulsation palpation

The investigators will subsequently thoroughly characterize various metabolic and anthropometric parameters and document any microvascular or macrovascular complications.

The patients will be annually rescreened for both NAFLD-related as cardiovascular variables. Therefore this study will assess the correlation between NAFLD, cardiovascular risk, and type 1 diabetes in a prospective manner.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Prevalence of NAFLD in type 1 diabetes: percentage of patients with indices of liver steatosis and/or NASH and/or fibrosis.
Periodo de tiempo: one year
Determination of the cross-sectional prevalence of NAFLD in a cohort of type 1 diabetes patient (population size approximately 1000 subjects) according to ultrasound criteria, FLI≥60, HSI≥36, controlled attenuation parameter >215dB/m (M-probe) or ≥250 dB/m (XL probe) and MRI-PDFF >5% hepatocyte steatosis (reference method). All measures will be performed in a combined and standardized protocol to explore their diagnostic accuracy (see outcome 4).

Incidence of NAFLD in type 1 diabetes.
Periodo de tiempo: five years
Incidence of NAFLD in type 1 diabetes determined by new cases of NAFLD according to ultrasound criteria, FLI≥60, HSI≥36, controlled attenuation parameter >215dB/m (M-probe) or ≥250 dB/m (XL probe) or MRI-PDFF >5% hepatocyte fat infiltration (reference method)

Periodo de tiempo: five years
The investigators will compare the abovementioned non-invasive tools to diagnose and grade liver steatosis and fibrosis with the predefined gold standard (MRI-PDFF for steatosis and magnetic resonance elastography for fibrosis). Correlations and agreement statistics will be performed for each index. Using regression analysis, a new specific algorithm will be developed based on cohort-specific cutoffs. Using longitudinal data, a prediction score will be determined to predict NAFLD occurrence or NAFLD progression.
