methacetin has been researched along with Hepatitis B in 1 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: A member of the class of acetamides that is paracetamol in which the hydrogen of phenolic hydroxy group has been replaced by a methyl group.
Hepatitis B: INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.

| 13C-Methacetin Breath Test for the Prediction of Outcome in in Acute Liver Injury or Acute Liver Failure[NCT02786836] | Phase 2/Phase 3 | 76 participants (Actual) | Interventional | 2016-06-10 | Completed | ||

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
| Intervention | percentage per hour (Mean) | |
|---|---|---|
| Day 1 or 2 MBT/transplant free survival at Day 21 | Day 1 or 2 MBT & Day 21 non-TFS | |
| 13C-Methacetin Breath Test (MBT) | 1.4 | 0.2 |
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
| Intervention | percentage per hour (Mean) | |
|---|---|---|
| Mean Peak PDR for TFS subjects at Day 21 | Mean Peak PDR for non-TFS subjects at Day 21 | |
| 13C-Methacetin Breath Test (MBT) | 10.2 | 1.9 |
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)
Timeframe: The first MBT reading either on Day 1 or Day 2 and Day 21
| Intervention | percentage per hour (Mean) | |
|---|---|---|
| Day 1 or 2 MBT & Day 21 TFS | Day 1 or 2 MBT & Day 21 non-TFS | |
| 13C-Methacetin Breath Test (MBT) | 9.1 | 2.3 |
