E.1.1.1 | Medical condition in easily understood language |
Liver cirrhosis is a chronic disease with progressive loss of liver function and generalized circulatory changes leading to development of comoplications including renal failure. |
Skrumpelever er en kronisk sygdom med progredierende tab af lever funktion og generelle kredsløbsændringer, som medfører udvikling af komplikationer inklusiv nyresvigt. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Many patients with cirrhosis will die of renal failure - the hepatorenal syndrome, which has a median survival of less than 1 month. Hepatorenal syndrome is treated with terlipressin, which increases blood pressure and improves renal function. However, terlipressin also causes a decline in cardiac function, which is unfortunate, since the renal function relies on a sufficient cardiac output. This may explain why only half of the patients respond to this treatment. We aim to investigate if renal function in patients with cirrhosis and ascites can be improved by combining terlipressin with dobutamin - a drug that increases cardiac function. Dobutamin increases cardiac output primarily by increasing heart rate. |
En stor del af patienter med skrumpelever vil dø af nyresvigt – det hepatorenale syndrom, hvor middeloverlevelsen er under 1 måned. Dette nyresvigt behandler man med stoffet terlipressin, som øger blodtrykket og bedrer nyrernes funktion. Terlipressin kan imidlertid også svække hjertets pumpeevne, hvilket er uheldigt, da nyrernes funktion er afhængig af hjertets pumpevne – dets minutvolumen. Dette er måske forklaringen på at kun knap halvdelen af patienterne responderer på denne behandling. Vi ønsker derfor at undersøge, om man ved at øge hjertets pumpeevne med stoffet dobutamin i kombination med terlipressin kan bedre nyrefunktionen hos patienter med skrumpelever og ascites. Dobutamin er et stof, der øger hjertets minutvolmen, primært ved at hæve pulsen.

E.5 End points |
E.5.1 | Primary end point(s) |
Primary end points: Glomerular filtration rate (GFR), and effective renal blood flow (ERPF) |
Primære endpoints er glomerulær filtrations rate (GFR), og effektive renale blodgennemstrømning (ERPF).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
End points are evaluated 3 times during the trial: 1) Baseline (0-60 min) 2) Period 1 (60-150 min): patients receive either dobutamine, terlipressin or placebo (natriumchloride) 3) Period 2 (150-240 min): Patients receiving dobutamine in period 1 receive terlipressin, patients receiving terlipressin in period 1 receive dobutamin. The placebo group continue with natriumchloride |
End points evalueres 3 gange under forsøget: 1) Baseline (0-60 min) 2) Periode 1 (60-150 min): patienter gives enten dobutamin, terlipressin eller placebo (natriumklorid) 3) Periode 2 (150-240 min): patienter som fik dobutamin i periode 1 gives terlipressin, patienter som fik terlipressin i periode 1 gives dobutamin. Placebogruppen fortsætter med natriumklorid. |
|
E.5.2 | Secondary end point(s) |
Secondary end points are: clearance of water, sodium, and lithium (CH2O, CNa, CLi), osmolar clearance, concentrations of hormones (renin, noradrenaline, aldosterone, proANP, proBNP), and cardiac variables (cardiac output, cardiac index, heart rate, mean arterial pressure). The study is of pathophysiological nature with one day of investigations, therefore we do not use classical end points such as treatment failure or death. The study is not confirmatory, hence several end points are applied. |
Sekundære endpoints er clearance af natrium og vand, (CNa, CH2O) samt clearance af lithium, osmolær clearance, hormonkoncentrationer (renin, noradrenalin og aldosteron, proANP, proBNP), samt hjerteparametre (minutvolumen, cardiac index, hjertefrekvens og middelarterieblodtryk). Studiet udføres som et patofysiologisk endagsstudie og opererer derfor ikke med klassiske endpoints som død, treatment failure og lignende. Dette er ikke et konfirmatorisk studie, hvorfor der opereres med flere endpoints. |
