简要总结
Background:
Hematopoietic stem cell transplant (HSCT) is a common treatment for many cancers and other illnesses. But many people who have HSCT go on to develop liver dysfunction. Researchers want to know more about how and why this happens. In this natural history study, they will try to learn what factors lead to liver dysfunction; how underlying liver disease may affect the results of HSCT; and how HSCT may contribute to liver dysfunction.
Objective:
To understand the links between HSCT and liver dysfunction.
Eligibility:
Adults aged 18 years or older and children 3 to 17 years who are being evaluated for HSCT.
Design:
This study involves 11 visits in 4 years. Most visits will be in the first year.
Before and after their HSCT, participants will undergo these tests:
Physical exam, including blood tests and a test of heart function. Participants will provide stool samples.
Liver biopsies. Samples of liver tissue will be removed. This may be done either by inserting a needle through the right side of the chest, or with a thin tube threaded to the liver from a vein in the neck. Adult participants will undergo this procedure 2 times: once before the HSCT and once about a year later.
Imaging scans. Participants will lie on a bed that moves into either a cylinder or a donut-shaped machine.
Ultrasound. Participants will lie still. A probe that uses sound waves will be slid over their skin to get pictures of the liver.
Fibroscan exam. This is like an ultrasound that uses a special probe to measure the toughness of the liver.

详细描述
Study Description:
Liver dysfunction is common in patients that have undergone hematopoietic stem cell transplant (HSCT) and is associated with increased mortality. We aim to study the natural history of liver dysfunction in HSCT, what factors contribute to the development of liver dysfunction, and how underlying liver disease affects complications and outcomes of HSCT. We hypothesize that those patients with underlying liver disease or those who develop liver disease have increased morbidity and mortality compared to those without liver disease.
Objectives:
Primary Objective:
To determine whether, at 3 months (Visit 7) after transplant, patients with liver disease at transplant are more likely to have died or have a total bilirubin >=4 mg/dL than those without liver disease at transplant.

结局指标
主要结局
Mortality rate
时间窗: 91 days after transplant
To determine whether, at 91 days after transplant, patients with liver disease at transplant are more likely to have died or have a total bilirubin \>=4 than those without liver disease at transplant.
Death or total bilirubin >=4 at 91 days after the transplant
时间窗: 91 days after transplant
To determine whether, at 91 days after transplant, patients with liver disease at transplant are more likely to have died or have a total bilirubin \>=4 than those without liver disease at transplant.
次要结局
