Active clinical trials for "Fibrosis"

Alcohol is the common precipitating factor for both cirrhosis of liver as well as alcohol related chronic pancreatitis. However, in real life clinical setting, clinicians do not frequently see many cases of symptomatic pancreatitis in patients who present with features of cirrhosis of liver. On the contrary, in some patients presenting with alcohol related chronic pancreatitis, evidence of cirrhosis of liver is observed on imaging without other clinical features of cirrhosis.

Due to providing valuable clinical information while being minimally invasive, blood-based testing will most likely be a prerequisite for future large-scale screening of high-risk populations. As a variety of pathological processes, including carcinogenesis, may cause changes in both the concentration and the structure and spatial arrangement of body biomolecules, the spectroscopic analysis of blood-based derivatives appears to be an appropriate tool for the early detection thereof. The differences observed in the spectral response of healthy individuals and patients may also be specific to a particular type/stage of the disease and, thus, may serve as a reliable diagnostic marker. In order to find sufficiently specific and sensitive biomarkers of early stages of degenerative and cancerous diseases, the co-applicant group at the Department of Analytical Chemistry, University of Chemistry and Technology Prague (UCT Prague), developed a unique approach for the spectroscopic analysis of blood plasma. Using the highly specialized, structure-sensitive methods of chiroptical spectroscopy (electronic circular dichroism - ECD, Raman optical activity - ROA) combined with conventional infrared (IR) and Raman spectroscopy, the first pilot studies yielded promising results with respect to the identification of spectral markers for pancreatic cancer, colon cancer and type 1 diabetes mellitus. In addition, metabolomics appears to be a very progressive approach to finding potentially suitable molecules to distinguish between healthy and cancer-affected individuals. Therefore, the investigators believes that this multimodal approach will allow for the identification of hepatocellular carcinoma (HCC). In our research, the focus will be on the identification of novel biomarkers in blood plasma that would exhibit sufficient sensitivity and specificity to detect early and potentially curable HCC stages, and that would be potentially useful for routine screening of this disease in well-defined at-risk groups.

The objective of this study is to determine what influences the patient and caregiver perception of care, and if this perception associates with the percentage of and what quality metrics are being met and outcomes. The investigators also plan to capture the cost of providing quality metrics and the cost of monitoring adherence to quality metrics.

Retrospective inclusion of lung cancers developed in a context of idiopathic pulmonary fibrosis, diagnosed and / or treated in participating centers. The cases are recovered retrospectively from the records of the pulmonology and pathology departments of our various partners.

Inflammatory aortitis probably represents a heterogeneous group, and the clinical experience accumulated over the last ten years, shared by the experts of the subject, is that the initial clinical, biological or radiological characteristics should make it possible to differentiate them and dismember the Nosological field. This will be an essential first step before studying prognosis, risk factors, and therapeutic options. The search for diagnostic criteria on a large series, similar to the study of classification of vascularites of the ACR in 1990, should make it possible to homogenize the diagnoses for the different teams working on the subject, and to begin work Collaborations, which alone can improve patient care in the future.

Hepatocellular carcinoma (HCC) has become the second most common cause of cancer death in the world, estimated responsible for nearly 745,000 deaths in 2012 (9.1% of all cancer deaths).

The aims of this study were divided into three parts: To develop a new software to carry out the functional-three- dimensional-reconstruction of the liver by 99mTc-GSA-SPECT scintigraphy To probe a new dynamic model of the metabolism of the 99mTc-GSA. To evaluate the liver function by 99mTc-GSA-SPECT scintigraphy before surgical treatment. Study design: Collectivity type: Prospective，randomized, controlled, multi-central clinical study. Patients: The subjects were from different hospitals including: Peking Union Medical College Hospital (PUMCH). Study arrangement: This study was consisted of three parts:

Patients with decompensated liver cirrhosis exhibit numerous hemodynamic and microvascular changes, i.e., low systemic blood pressure and peripheral vasodilatation. In addition, alterations of tissue oxygenation are described in these patients. Near-infrared spectroscopy (NIRS) has been proposed as a tool to quantify microvascular dysfunction, for example in patients with sepsis (1) or after trauma (2). NIRS is a non-invasive technique that uses the differential absorption properties of oxygenated and desoxygenated hemoglobin to evaluate skeletal muscle oxygenation (3). Up to the investigators' knowledge no data exist on NIRS measurements in patients with decompensated liver cirrhosis. Aims of this study are to evaluate: Are there any changes in NIRS parameters in patients with decompensated liver cirrhosis in comparison to other critically ill patients (matched to SAPS II Score) or healthy individuals? Is there a correlation with common accepted prognostic scores (MELD Score or indocyanin green clearance) in decompensated liver cirrhosis patients and initial NIRS parameters? Does the NIRS trend within the first three days of ICU care in decompensated liver cirrhosis patients receiving fluid replacement therapy correlate with the course of disease?

This is a multi-center cross-sectional study in which the Real-time Tissue Elastography® measurements will be collected prospectively from patients with chronic hepatitis B or C virus presenting for liver biopsy.

The CTP score is one of the best proved severity score in predicting mortality in patients with cirrhosis. Portal hypertension and variceal bleed are significant causes of morbidity and mortality in patients with cirrhosis. The recently published CTPK score included variceal variceal bleed status to the CTP score which improved the accuracy of CTP score in predicting short term mortality. CTPK score needs prospective validation.
