Study summary

Investigate serial plasma samples of fibroblast growth factor 19 (FGF19) after oral stimulation with chenodeoxycholic acid in the same subjects before and after elective cholecystectomy

Read the detailed description

Lack of FGF19 and elevated 7-alpha-hydroxy-colestenone (C4) is associated with the bile acid diarrhoea (BAD), a disease with increasing estimated of prevalence.

BAD is occasionally triggered by cholecystectomy and FGF19 and C4 is known to be affected by cholecystectomy. The investigators are exploring if FGF19 after oral stimulation can be developed to a universal test for BAD, and need to know how the proposed test is affected by cholecystectomy.

What researchers measure

Primary outcomes

  1. Change in Stimulated Fibroblast Growth Factor 19 (FGF19) From Baseline Before Versus Post Cholecystectomy

    Change from baseline to after cholecystectomy in median chenodeoxycholic acid (CDCA) plus meal stimulated FGF19 (delta 0 min to 150 min after stimulation)

    Time frame: baseline and 3 - 5 months after cholecystectomy

Secondary outcomes

  1. Change in Chenodeoxycholic Acid (CDCA) Absorption to Plasma From Baseline Before Versus After Cholecystectomy

    Change from baseline to after cholecystectomy in median unconjugated CDCA plus meal stimulated absorption of unconjugated CDCA to measured in plasma (total area under the CDCA curve with measurement at fasting ie. t=0 minutes and subsequently at 60, 90, 120, and finally at 150minutes.

    Time frame: baseline and 3 - 5 months after cholecystectomy

  2. Change in Fasting 7-alpha-hydroxy-cholestenone (C4) From Baseline Before Versus After Cholecystectomy

    Change from baseline to after cholecystectomy in fasting C4

    Time frame: baseline and 3 - 5 months after cholecystectomy

  3. Change in Lipid Status From Baseline Before Versus After Cholecystectomy

    Change from baseline to after cholecystectomy in plasma triglycerides

    Time frame: baseline and 3 - 5 months after cholecystectomy

  4. Change in Stool Frequency From Baseline Before Versus After Cholecystectomy

    Change from baseline to after cholecystectomy in number of stools as a mean of a seven-day diary baseline versus after cholecystectomy. That is the diary results for each study participant is tallied using mean values. The tallying of these diary results is done using medians. Therefore the unit used is 'mean stools per day' and this is reported with medians

    Time frame: baseline and 3 - 5 months after cholecystectomy

  5. Change in Stool Pattern Correlated to FGF19

    Spearman correlation between change from baseline to after cholecystectomy in FGF19 and in mean number of stools

    Time frame: baseline and 3 - 5 months after cholecystectomy

  6. Change in Patient Reported Diarrhea Symptoms Correlated With Change in C4 From Baseline Before Versus After Cholecystectomy

    Correlation between patient reported frequency of diarrhea (gastrointestinal quality of life index item 31) and fasting C4 before versus after cholecystectomy

    Time frame: baseline and 3 - 5 months after cholecystectomy

  7. Change in C4 Total Area Under the Curve From Baseline Before Versus After Cholecystectomy

    Change in total AUC for C4 between visit 1 and visit 2

    Time frame: before cholecystectomy and 3-5 months after cholecystectomy

  8. Change in Fasting FGF19 From Baseline Before Versus After Cholecystectomy

    change in fasting FGF19 before versus after cholecystectomy

    Time frame: before and 3-5 months after cholecystectomy

  9. Change in Patient Reported Diarrhea Symptoms Correlated With Change in FGF19 From Baseline Before Versus After Cholecystectomy

    Correlation between patient reported frequency of diarrhea (gastrointestinal quality of life index item 31) and fasting FGF19 before versus after cholecystectomy

    Time frame: baseline and 3 - 5 months after cholecystectomy

  10. Change in Stool Consistency (Bristol Stool Type) From Baseline Before Versus After Cholecystectomy

    Change from baseline to after cholecystectomy in mean Bristol type per stool as of a seven-day diary baseline versus after cholecystectomy. The Bristol scale divides stool into seven categories from 1 (hard lumps) to 7 (completely watery stool). The diary shows pictograms with short text descriptions.

    Time frame: baseline and 3 - 5 months after cholecystectomy

Adverse events

Collected over Adverse events were registered in relation to administration of chenodeoxycholic acid both at visit 1 and visit 2 (separated by 3-5 months). Registration started at time of administration of chenodeoxycholic acid (one dose) and the registration lasted four days after this. At day three after the administration standard liver biochemistry was measured (ALT, Alk. phospatase, INR, bilirubin).. Non-serious events are listed at a 5% frequency threshold.
