BACKGROUND AND AIMS: NAFLD prevalence is increasing worldwide.
AIM: to assess whether severity of hepatic, metabolic and cardiovascular (CV) disease changed over time.
METHODS: 422 NAFLD patients (388 biopsy proven and 34 clinical cirrhosis) diagnosed between 1990 and 2021 and subdivided according to decade of presentation. Metabolic parameters, early atherosclerosis (carotid plaques at Doppler ultrasound), severity of liver damage (NAS score, NASH, significant fibrosis (≥2) and cirrhosis) and PNPLA3 genotyping were assessed.
RESULTS: No difference in age, sex and prevalence of dyslipidemia and hypertension was found across decades (p for trend), whereas a higher prevalence of diabetes (p = 0.02), obesity (p<0.001), histological severe steatosis (p<0.001), NASH (p<0.001), fibrosis ≥2 (p<0.001), cirrhosis (p<0.001) and carotid plaques (p = 0.05) was observed in the last decade compared to the others. A higher prevalence of PNPLA3 GG polymorphism was found over time (p = 0.02). In the whole cohort, age, metabolic alterations and PNPLA3 G homozygosity were independent risk factors for hepatic fibrosis and carotid plaques, independently of the decade considered.
CONCLUSION: Over the past 10 years compared to previous decades, NAFLD patients presented to observation with more severe liver disease and subclinical atherosclerosis, paralleling the spread of diabetes and obesity. PNPLA3 unfavorable genotype became more prevalent over time.
