methacetin and Liver Cirrhosis

methacetin has been researched along with Liver Cirrhosis in 36 studies

methacetin: RN given refers to parent cpd
methacetin : A member of the class of acetamides that is paracetamol in which the hydrogen of phenolic hydroxy group has been replaced by a methyl group.

Liver Cirrhosis: Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules.

Trial Outcomes

Cumulative Percent Dose Recovery 20 (cPDR20) Value

The relationship between the cPDR (cumulative PDR of metabolized 13C-Methacetin 20 minutes after ingestion) in single time points of MBT measurements and TFS and non-TFS (death/transplant) at Day 21. (NCT02786836)
Timeframe: The first MBT reading either on Day 1 or Day 2 and Day 21

Interventionpercentage per hour (Mean)
Day 1 or 2 MBT/transplant free survival at Day 21Day 1 or 2 MBT & Day 21 non-TFS
13C-Methacetin Breath Test (MBT)1.40.2

Peak Percent Dose Recovery (PDR) Value

Peak PDR is the maximal percent dose recovery (PDR) rate which reflects the maximum rate of metabolism of 13C-methacetin measured as the change in 13CO2 / 12CO2 (normal carbon dioxide) ratio after ingestion of 13C-methacetin normalized using the patient's height and weight. The distributions of mean PDR Peak values were compared between TFS (transplant free survival) and non-TFS (death/transplant) at Day 21. (NCT02786836)
Timeframe: Days 1 and 21

Interventionpercentage per hour (Mean)
Mean Peak PDR for TFS subjects at Day 21Mean Peak PDR for non-TFS subjects at Day 21
13C-Methacetin Breath Test (MBT)10.21.9

Peak Percent Dose Recovery (PDR) Value

This outcome is similar to the peak PDR defined in the primary outcome but as a secondary we are looking at Day 1 or Day 2 peak PDR values. Peak PDR is the maximal percent dose recovery (PDR) rate which reflects the maximum rate of metabolism of 13C-methacetin measured as the change in 13CO2 / 12CO2 ratio after ingestion of 13C-methacetin normalized using the patient's height and weight. The distributions of mean PDR Peak values were compared between TFS and non-TFS (death/transplant) at Day 21. (NCT02786836)
