研究概览
简要总结
Randomized, open label study of intravenous terlipressin infusion vs. bolus for the treatment of variceal hemorrhage. 24 hour regimen consisting of intravenous terlipressin will be used either at a rate of 0.5mg/hour or 2mg bolus every 4 hourly. Participants will be randomized into intervention and control arm using block randomization by computer generated random numbers. Efficacy will be assessed by clinical improvement in symptoms and signs of GI bleed. To assess safety, frequency and degree of adverse reactions will be observed. Periodic assessments until 5 days will be done consisting of physical examination, safety assessments, vital signs and lab tests.
详细描述
Randomized, open label trial, conducted on patients admitted with acute variceal hemorrhage at The Aga Khan University Hospital, Karachi (AKUH). Patients will be followed in clinic after discharge to assess survival for 6 weeks.
Intravenous terlipressin will be obtained from Clinical Trials Unit, AKUH pharmacy in standard IV infusion form. Following complete clinical and laboratory evaluation, assessing the patient for eligibility, informed consent will be obtained from all the participants who are willing to be part of this study. After obtaining the informed consent, study participants will be randomized into the intervention arm (continuous infusion of Terlipressin) or the control arm (bolus form of Terlipressin). Participants who are randomized to the intervention arm will be administered a continuous infusion of Terlipressin at a rate of 0.5mg/hour for the first 24 hours. Participants randomized into the control group will be administered a bolus form of Terlipressin at a rate of 2mg every six hourly for the first 24 hours respectively. In case of weekends/public holidays intravenous terlipressin will be obtained from the main pharmacy of AKUH.
The trial will be conducted in in-patient units of AKUH where eligible patients are admitted. It may include emergency room, special care unit and general ward. Moreover, patients will be followed up by phone calls and in outpatient's clinics to assess survival six weeks post discharge.

结局指标
主要结局
Reduction in tachycardia, measured through heart rate (>100 bpm) being displayed in the electronic monitors in wards, emergency room and out-patient clinics
时间窗: 6 weeks (Overall length of follow-up)
It will be assessed by trained research coordinator as; the number of study participants with 20% reduction in tachycardia as compared to the baseline between the two arms.
Improvement in mean arterial pressure, being displayed in the electronic monitors in wards, emergency room and out-patient clinics
时间窗: 6 weeks (Overall length of follow-up)
It will be assessed by trained research coordinator as; the number of study participants with 20% improvement in mean arterial pressure as compared to the baseline between the two arms. Adverse events related to terlipressin, such as hyponatremia, diarrhea, abdominal pain; arterial hypertension should be reported to the primary gastroenterologist between the two arms.
In-patient hospital mortality, assessed through medical records.
时间窗: Admission of patient till death in the hospital
It will be assessed through medical records, by a trained research coordinator as the number of study participants dying within the hospital between the two arms.
Failure to control bleeding as assessed by physiological parameters in the blood
时间窗: Admission of patient till discharge from the hospital
It will be assessed by a trained research coordinator as the number of participants having fresh hematemesis and 3 gm drop in hemoglobin (9% drop in hematocrit) within a 24 hours' time period between the two arms.
Incidence of Treatment-Emergent Adverse Events (Safety and Tolerability)
时间窗: 6 weeks (Overall length of follow-up)
It will be assessed by trained research coordinator as; the number of participants having experienced any adverse events such as hyponatremia, diarrhea, abdominal pain, arterial hypertension, 5 days after having terlipressin drug, between the two arms.
次要结局
- Prolong hospital stay (> 5 days) as assessed through medical records and pre-designed questionnaire(5 days after admission till being discharged from the hospital)
- Out of hospital mortality assessed through telephonic interviews from patient's caregiver(5 weeks after being discharged from the hospital)
- Failure to control bleeding as assessed by physiological parameters in the blood(5 weeks after being discharged from the hospital)
