Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Degree of suppression of endogenous bile acid synthesis [Decrease in urine 3 alpha,7 alpha -dihydroxycholestanoic acid (DHCA) and 3 alpha,7alpha,12 alpha - trihydroxycholestanoic acid (THCA) bile acid intermediates and increase in FGF-19] 2. Increase in normal primary bile acids [increase in urine cholic acid (CA)] 3. Change in fat soluble vitamins levels (T= 24 weeks versus T= 42 weeks) 4. Change in weight gain (weight-for-height percentile) (T= 36 weeks versus T=72 weeks) 5. Change total body length growth rate (cm/year; only in those with remaining growth potential) 6. Feasiibility and side effects of cholic acid supplementation; diarrhea, vomiting, liver dysfunction and others Measured at 0, 24, 36, 48, 72 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Change in seizure frequency 2. Change in the obtained developmental mile stones 3. Change serum transminases and ?-glutamyltrans- peptidase levels 4. Change in fibroscan liver elasticity measurements 5. Change in liver protein synthesis 6. Change in markers of peroxisomal / mitochondrial functioning Measured at 0, 24, 36, 48, 72 weeks | — |
