Filter by:The primary purpose of the study is to characterize the current standard of care, clinical course, and outcomes of pregnant women and their offspring at high risk for early onset severe hemolytic disease of the fetus and newborn (EOS-HDFN).
This study is an ancillary (add-on) study to the clinical trial entitled "Effect of Nitric Oxide in Cardiac Surgery Patients With Endothelial Dysfunction", which has Clinical Trials.gov identifier NCT02836899. NCT02836899 trial randomizes cardiac surgical patients to receive either Nitric Oxide (NO) or a placebo during and after cardiac surgery. This ancillary study aims to assess the effects of Nitric Oxide on vascular responsiveness and on endothelial function during hemolysis in patients with pre-operative endothelial dysfunction undergoing cardiac surgery requiring prolonged cardiopulmonary bypass.
Diarrhea-associated hemolytic uremic syndrome (D+HUS) is defined as a prodrome of enteritis followed by thrombocytopenia (< 150,000/mm3), microangiopathic hemolytic anemia, and signs of variable degrees of renal damage (increase in serum Cr, proteinuria, and/or hematuria) . Our aim is to detect the most reliable early predictors of poor prognosis to identify children at major risk of bad outcome who could eventually benefit from early specific treatments.
Home HD (HHD) is associated with better outcome in end-stage renal disease patients compared to in-center HD, in particular in terms of quality of life. However fear of AVF cannulation is a known barrier for patient's choice and adoption of a HHD program. Providing nurse assistance for the cannulation can help developing HHD programs. The aim of this study is to evaluate the feasibility of assisted home hemodialysis, with the intervention of a nurse at home for arterio-venous fistula cannulation.
Fluid restriction is necessary among patients with chronic kidney disease. However, treatment adherence remains a challenge. Hence, this study determined the effects of a fluid distribution timetable on adherence to fluid restriction of patients with end-stage renal disease undergoing hemodialysis. This study used a single-blind, randomized-controlled pilot study design. Patients with end-stage renal disease were randomly-assigned using computer-generated sequences of randomly permuted blocks stratified according to sex to receive the fluid distribution timetable or standard care. Adherence to fluid restriction was measured using two indicators - thirst and interdialytic weight gain - and were compared using One-way RM-MANOVA and MANCOVA. Secondary outcomes included baseline patient demographic and clinical characteristics and were compared according to treatment allocation. Both groups were followed-up for four weeks, assessing outcome measures during the second hemodialysis session for each week.
Haemolytic uremic syndrome (HUS) is defined by the presence of the classic triad of non-immune microangiopathic hemolytic anemia (negative direct Coombs), thrombocytopenia and acute renal failure. Histological lesions of HUS are characterized by a systemic thrombotic microangiopathy (TMA), which mainly affects the renal vessels, with wall thickening, thrombosis and obstruction of the vascular lumen. Atypical HUS (aHUS) is a subtype of HUS in the TMA phenomena that results from the loss of regulation of the alternative complement pathway on cell surfaces and is generally considered to be from a genetic cause. Approximately 10% of HUS cases are classified as atypical HUS, which are associated with a more adverse prognosis, with a mortality rate up to 25% and progression to end stage renal disease in more than 50% of cases.
Regular physical exercise was adapted to the situation of the patient with hemodialysis to help improve the quality of life of the patient
Eculizumab is a humanized monoclonal IgG antibody against protein C5 that works to inhibit the activation of the terminal complement cascade. The Eculizumab is currently FDA approved for the treatment of Paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome (aHUS) and has been shown to improve the quality of life and overall survival in these patients. aHUS is a life-threatening disease of complement mediated thrombotic microangiopathy often triggered by an inciting event, such as an infection or immunocompromised state. Pregnancy has also been identified as an inciting event, with patients most often experiencing aHUS in the postpartum period. Due to its rare nature, pregnancy-associated aHUS is often mistaken for preeclampsia or hemolysis, elevated liver enzyme, low platelet (HELLP) syndrome. As standard treatment for preeclampsia and HELLP syndrome is completion of the pregnancy by expediting delivery of the baby. A missed diagnosis of aHUS can result in delays in treatment, including use of Eculizumab when appropriate; such delay can increase the risk of maternal morbidity and mortality. When aHUS is suspected in the postpartum period, Eculizumab could be initiated early; however, there is limited data on use of Eculizumab in this setting.
The purpose of this study is to evaluate the safety and efficacy of parsaclisib administered orally to participants with autoimmune hemolytic anemia (AIHA) who have decreased hemoglobin and evidence of ongoing hemolysis that requires treatment intervention.
Hematopoietic stem cell transplantation (HCT)-associated thrombotic microangiopathy (TMA) is an understudied complication of HCT that significantly affects transplant related morbidity and mortality. The investigators hypothesize that early intervention with complement blocker eculizumab will double survival in HCT recipients with high risk TMA, as compared to historical untreated controls. An optimal eculizumab dosing schedule can be determined for this population through eculizumab pharmacokinetic/pharmacodynamic (PK/PD) testing.
