Active clinical trials for "Fibrosis"

We hypothesized that the multi-disciplinary assessment of interstitial lung disease patients would lead to a more accurate diagnosis and consequently alterations in treatment regimens that may lead to improved outcomes.

The purpose of this study is to determine whether urinary connective tissue growth factor (uCTGF) can predict the onset of fibrosis in transplanted kidneys.

Liver transplant is the goal treatment for every patient with end-stage chronic liver disease. Quality of life improves after transplant because the main complications of end-stage liver disease disappear, but due to immunosuppression other alterations appear such as metabolic alterations, weight gain, among others. Body composition and nutritional status can be affected do to post-transplant pharmacologic therapy.

This national multicenter prospective study is aimed to study the diagnositic performance of STE/STQ elastography in liver fibrosis and prognosis in patients with chronic hepatitis B infection.

Hepatopulmonary Syndrome is a respiratory complication of liver cirrhosis defined as a triad: hypoxemia (PaO2 < 80 mmHg in room air), chronic liver disease and intrapulmonary vasodilatations. Its prevalence varies between 4 and 32%. Numerous treatments have been tried but the only efficient therapy to cure the syndrome is liver transplantation. Without transplantation it is associated with a higher mortality which is the reason why hepatopulmonary syndrome patients have a higher priority to transplantation. However it appears in some restricted studies that hepatopulmonary syndrome is associated with more postoperative complications (infections, vascular and biliary complications, prolonged length of mechanical ventilation…). The investigators hypothesised that hepatopulmonary syndrome patients have more postoperative complications after liver transplantation than non hepatopulmonary syndrome patients matched on age, MELD (Model for End-Stage Liver Disease) score, comorbidities, perioperative transfusion and noradrenaline doses.

It is an observational study of non alcoholic fatty liver disease (NAFLD) patients with a calculated sample size of 90. Liver biopsy proved NAFLD patients will be recruited in this study for 2 years follow-up. Patients will be assessed at baseline, at every six months for blood count, liver function test, fasting blood-glucose, fasting insulin, ferritin, liver ultrasonography, and liver stiffness.

Background: With the advances in treatment and clinical care, individuals with human immunodeficiency virus (HIV) infection have experienced an increase in life expectancy. Liver disease is common among HIV-infected patients due to the shared routes of transmission of HIV and viral hepatitis. Nonalcoholic fatty liver disease (NAFLD) is the most common cause of elevated aminotransferases in HIV-monoinfected adults without HBV or HCV. Vibration-controlled transient elastography (VCTE) has been shown to have good sensitivity and specificity for assessment of liver fibrosis in HIV and viral hepatitis coinfected patients, as well as in HIV-negative NASH population. Controlled attenuation parameter (CAP), a novel physical parameter developed using the postulate that fat affects ultrasound propagation, measures the ultrasound attenuation at the center frequency of the FibroScan®. Study design: This is a prospective observational study. Objective: The aim of this study is to evaluate the liver steatosis and fibrosis in HIV-infected patients by noninvasive methods of VCTE and CAP. Methods: Patient number: 200 Inclusion criteria: Age: 20-65 years Males and females with HIV infection diagnosed by infection doctors Willing and able to comply with the study requirements Willing and able to provide written informed consent to participate in the study Exclusion criteria: Pregnancy Unable to complete the noninvasive procedure of VCTE and CAP Unwilling to provide written informed consent to participate in the study

The association of T1-mapping (both native and ECV) and strain analysis of LV and RV by CMR will be assessed. Results from strain analysis will be investigated in terms of their prognostic value.

The main purpose of the present study is to compare the diagnostic performance of three non-invasive stiffness imaging methods (TE, SWE and MRE) in a consecutive cohort of patients with chronic viral C hepatitis or co-infected by HCV+ Human Human Immunodeficiency Virus (HIV).

This is a small pilot / feasibility study (Approximately 50 patients) to assess the possibility of clinical implementation of MRI assessment of patients with cystic fibrosis and primary ciliary dyskinesia. Patients will undergo their standard CT imaging and lung function investigations and additionally will undergo MRI examination. Reports from CT (the current gold standard) and MRI will be assessed for concordance and patient acceptability and examination implementation costs will also be assessed. Novel MRI-based potential markers of CF and PCD disease state will also be assessed.
