Key result

Carriers of APOC3 variant alleles had a significantly higher prevalence of nonalcoholic fatty liver disease compared with wild-type homozygotes (38% vs 0%; P<0.001).

Why the study?

Are APOC3 variant alleles associated with nonalcoholic fatty liver disease and insulin resistance in healthy men?

Population

258 healthy men, comprising an initial cohort of 95 Asian Indian men and a validation cohort of 163…

Overview

APOC3 variants were associated with higher NAFLD prevalence; hypothesis-generating and should not yet change practice or screening.

Type

Observational (n=258)

Structured PICO

Are APOC3 variant alleles associated with nonalcoholic fatty liver disease and insulin resistance in healthy men?

P
Population
258 healthy men (95 Asian Indian and 163 non-Asian Indian) assessed for APOC3 genotypes, insulin resistance, and nonalcoholic fatty liver disease.
E
Exposure
Carriers of APOC3 variant alleles (C-482T, T-455C, or both)
C
Comparator
Wild-type homozygotes for APOC3
O
Outcome

Main Result

Absolute Event Rate: 38% vs 0%

p-value: p=<0.001

APOC3 gene variants (C-482T and T-455C) are strongly associated with nonalcoholic fatty liver disease, hypertriglyceridemia, and insulin resistance in healthy men.

Cite This Study

Petersen et al. (2010) conducted an observational in Nonalcoholic fatty liver disease (n=258). APOC3 variant alleles (C-482T, T-455C, or both) vs. Wild-type homozygotes was evaluated on Prevalence of nonalcoholic fatty liver disease (p=<0.001). Carriers of APOC3 variant alleles had a significantly higher prevalence of nonalcoholic fatty liver disease compared with wild-type homozygotes (38% vs 0%; P<0.001).
