Filter by:This was a Phase 2, open label, single arm, multiple dose study to assess efficacy, safety, pharmacokinetics and pharmacodynamics of iptacopan when administered in addition to Standard of care (SoC) in patients with paroxysmal nocturnal hemoglobinuria (PNH) with signs of active hemolysis.
This study will be investigating how a common blood test for identifying heart damage (Troponin T) is affected by red blood cell damage in the blood sample (Haemolysis). It is already known that damage to the red blood cells during or after blood sample collection can cause falsely low test results however the exact amount is not clear. Some previous studies suggest that a much higher amount of red blood cell damage could be allowable when reporting the test results. This study will mimic the type of red blood cell damage that occurs in the hospital and determine what degree of damage or 'haemolysis' causes a significant reduction in the test result and therefore determine an allowable limit for safely reporting the test result. The results of this study may help provide an evidence based approach to improving current practice and may lead to fewer rejected blood samples, fewer repeat tests, improved A&E treatment times, general cost savings and an improved service to patients.
To evaluate the effect of hemodialysis on various ophthalmologic parameters in patients with end-stage kidney disease (ESRD).
The primary purpose of this clinical investigation is to establish the performance of the GenePOC Strep A, C/G assay on the revogene. This will be achieved by comparing the test to a conventional method for detection of Group A β-hemolytic Streptococcus (GAS) and pyogenic Group C and G β-hemolytic Streptococcus (GCS/GGS) in throat swab samples.
Group A Streptococcus (GAS) infection is a major cause of death and disability globally with a disproportionately high burden in settings of disadvantage worldwide. Acute infections due to GAS range from very common superficial skin infections (>150 million prevalent cases) and pharyngitis (over 600 million incident cases) to life-threatening invasive disease (>600,000 incident cases) such as necrotising fasciitis. Post-infectious GAS sequelae of GAS include acute rheumatic fever (ARF, ~500,000 incident cases) leading to rheumatic heart disease (RHD, ~34 million prevalent cases), and acute glomerulonephritis. The health services impact of GAS disease in all its forms is immense and strikes at every level from primary to intensive care. Controlled human infection models (CHIMs) have a long history of critical contributions to vaccine development. Data from CHIMs meeting modern scientific, regulatory, and ethical standards, are aiding efforts to control over 25 major human pathogens, including bacteria (e.g. pneumococcus, cholera), viruses (e.g. respiratory syncytial virus, influenza), and parasites (e.g. malaria, schistosomiasis). A reliable and safe controlled human infection model of GAS pharyngitis will be an important part of the global vaccine development effort. To build the model, the investigators are undertaking a dose-ranging study using an observational, dose-escalation, inpatient trial to determine the dose of GAS administered by direct oropharyngeal inoculation (bacteria 'painted' onto throat) required to reliably produce a pharyngitis attack rate of ≥ 60% in carefully screened healthy adult volunteers.
The main purpose of our study is to investigate whether haemodialysis itself affects the efficacy of antiplatelet drugs and the effects of two different types of dialysis membranes (polysulfone membranes and polyamide membranes) on antiplatelet efficacy. A total of 60 patients with ESRD and under dual-antiplatelet treatmen for at least 5 days will be enrolled and divided into the Clopidogrel group (clopidogrel 75mg qd;aspirin 100mg qd, n=30) and the Ticagrelor group (ticagrelor 90mg bid; aspirin 100mg qd, n=30). All included patients will receive haemodialysis by two different types of dialysis membrane.Platelet aggregation of venous blood from all patients will be detected by LTA and VerifyNow immediately before and after two times of haemodialysis.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of Cemdisiran in patients with aHUS.
The investigators propose a randomized study to compare bovine carotid artery (BCA) biologic grafts and expanded polytetrafluoroethylene grafts (ePTFE) for permanent hemodialysis access.
This study will provide feasibility data regarding the conduct of a clinical trail evaluating the use of early aggressive inpatient intravenous rehydration in children with Shiga Toxin producing E. coli infection.
Autoimmune hemolytic anemia is characterized by shortened red blood cell survival and a positive Coombs test. The responsible autoantibodies may be either warm reactive or cold reactive. The rate of hemolysis and the severity of the anemia may vary from mild to severe and life-threatening. Diagnosis is made in the laboratory by the findings of anemia, reticulocytosis, a positive Coombs test, and specific serologic tests. The prognosis is generally good but renal failure and death sometimes occur, especially in cases mediated by drugs.
