Low Childhood Cholesterol Absorption Predisposes to Gallstone Disease: The Cardiovascular Risk in Young Finns Study

Objectives: Unraveling pathogenesis of gallstones could help to diminish its enormous disease burden. We hypothesized that certain properties of childhood cholesterol metabolism predict gallstone disease in adulthood.

Methods: Childhood serum cholestanol and plant sterols (surrogates for cholesterol absorption), cholesterol precursors (surrogates for cholesterol synthesis), lipids, demographics, and dietary habits were compared between individuals diagnosed with gallstone disease subsequently in adulthood (n = 95) and control subjects (n = 190) matched for age, sex, and body mass index in 1980. Subjects were participants of prospective Cardiovascular Risk in Young Finns Study.

Results: In 1980, at mean age of 11.4 years gallstone cohort was characterized by 5.8% lower cholestanol (P = 0.038), and 11.2% to 12.2% (P range = 0.003-0.008) lower plant sterols campesterol, sitosterol, and avenasterol compared with controls. Mean lathosterol/sitosterol ratio was 16.3% higher in gallstone compared with control cohort (P = 0.028). Female gallstone group had 5.4% lower mean cholestanol compared with controls (P < 0.05), and, respectively, those of campesterol, sitosterol, and avenasterol were 12.7% to 14.0% lower (P < 0.05 for each). Body mass index was inversely related to cholestanol and sitosterol (r range = -0.161 to -0.208, P < 0.05 for each) in controls, but not among patients with gallstone. In whole study population, surrogates of cholesterol absorption (eg, campesterol, P = 0.018) and low dietary intake of vegetables (P = 0.009) were significant predictors of gallstones in logistic regression model.

Conclusions: Cholesterol metabolism trait characterized by low serum levels of surrogate markers of cholesterol absorption precedes adult gallstone disease already in childhood. Low serum cholestanol and plant sterol ratios during normal Western diet may have role as predictive biomarkers for gallstones.
