Active clinical trials for "Hematologic Diseases"

Clostridium difficile causes ~453,000 infections and ~29,300 deaths per year in the US, making it the most common hospital acquired infection in the country. C. difficile is an anaerobic bacterium that has the capacity to inhabit the colon of humans and other mammals. Initially thought to be a commensal, it was later found to be associated with antibiotic induced enterocolitis. Since then, it has gradually become one of the most important healthcare associated pathogens. C. difficile infection (CDI) causes colitis, which is inflammation of the colonic mucosa with a spectrum of severity from mild to more protracted diarrhea, abdominal pain, fever, toxic megacolon, sepsis, and in some instances death. Mortality occurs despite the existence of three antibiotic options. CDI is also associated with higher hospital readmission rates, and associated healthcare costs in the US are estimated at 4.8 billion dollars annually. Due to the significance of C. difficile in healthcare, hospital level C. difficile rates are publically reported and closely scrutinized by the Centers for Medicare and Medicaid. Standard infection control bundles are proving to be insufficient for controlling the national C. difficile problem. Better understanding of the biological steps preceding clinical infection and reversal of the underlying gut dysbiosis will allow us to curtail our C. difficile epidemic. The present study aims to manipulate the gut microbiota to halt the biological progression of C. difficile. CDI is a serious problem in hematology-oncology patients. The incidence of CDI in the hematology-oncology population is much higher than in other populations and hematology-oncology inpatient units frequently have the highest incidence of CDI cases within an institution. Additionally, hematology-oncology patients have high rates of C. difficile colonization upon hospitalization and more than 50% of patients detected with C. difficile colonization before bone marrow transplantation end up diagnosed with hospital associated CDI. This finding is not trivial as CDI treatment with oral vancomycin causes major and prolonged perturbations of their intestinal microbiota, which has been associated with higher mortality. In addition to the usual complications of CDI, a higher incidence of graft-versus-host-disease has been described in patients with CDI.

To determine how long blood transfusions are needed for primary stroke prevention. Also, to determine the duration of risk associated with abnormal transcranial Doppler ultrasound (TCD) and to determine the specificity of the stroke risk model developed in STOP 1 in patients with abnormal TCD measurements.

To assess the outcomes of NRM when administering pharmacologic pretransplant immunosuppression (PTIS) followed by pretransplant reduced toxicity conditioning (RTC) and an allogeneic stem cell transplant (allo-SCT) and post-transplant graft-versus-host disease prophylaxis based on post-transplant cyclophosphamide (PT-Cy) in patients with inherited blood disorders.

This study aims to examine the effect of ginger beverage consumption on platelets activity in apparently healthy Saudi adult volunteers. As for the Saudi population, consumption of powdered ginger dissolved in hot water is a common practice. Accordingly, in this study, it is tempting to speculate the effect of this form of ginger consumption, given in separate time points per day, on platelet aggregation profile by using platelet aggregation analogues. If positive results were obtained, the herb could provide natural protection against the development of platelet aggregation complications and could be a potential alternative to aspirin, used for improving blood circulation and hematological pathophysiologies in diseased individuals.

The goal of this clinical research study is to find the dose of EZN-2232 that can be given to MBL deficient pediatric cancer patients undergoing chemotherapy. The pharmacokinetics, pharmacodynamics, and safety of the study drug will also be studied.

This protocol, UMCC 2012.047, was a pilot study initially intended for 12 subjects. After completing enrollment of the planned 12 subjects, we are extending the study to an additional 25 subjects. The trial will examine the safety and efficacy of the addition of vorinostat, the study drug, to standard medications to try to prevent or lower the risk of graft versus-host disease (GVHD) for recipients of unrelated (matched) donor, blood or marrow stem cell transplants. The transplant regimens, chosen according to current institutional policy, will depend upon the recipients underlying disease (their blood cancer or other blood disorder), previous therapy, and current health issues. GVHD prophylaxis (preventive drug intervention) will be the local institutional standard for post-transplant immunosuppression, including tacrolimus and methotrexate, plus vorinostat. Vorinostat will be given twice daily orally beginning 10 days prior to the recipient's transplant and continue for up to 100 days after transplant.

The purpose of the study is to determine whether oral contraceptives, desmopressin acetate, and/or tranexamic acid are effective in the treatment of women with menorrhagia who are diagnosed with a bleeding disorder.

HSCT associated thrombotic microangiopathy(TA-TMA) is a heterogeneous, fatal disorder seen within 100 days post-transplant and presents with thrombocytopenia, hemolysis, acute renal failure, mental status changes and involvement of other organs. N-Acetylcysteine (NAC) is a small, simple molecule that began as a generic drug almost 40 years ago. It has since been approved by the FDA for many indications. The investigators conducted an prospective clinical trial to evaluate the safety and efficiency of NAC in patients with TA-TMA.

in this study , effectiveness of supragingival irrigators containing chlorhexidine is compared with routine oral health measures in patients with blood dyscrasia whom can not use effective oral health measures(e.g brushing ) due to their systemic condition(e,g,neutropenia ,thrombocytopenia,..)

The purpose of this study is to see how long lenalidomide therapy can maintain or improve the disease response obtained after induction therapy that does not include lenalidomide, pomalidomide or thalidomide; and consequently reduce worsening of disease and to evaluate the activity of lenalidomide. Patients will receive lenalidomide or be under observation. All patients will attend regular clinic visits to evaluate their disease and health. Patients will have the option to participate in additional biomarker correlative studies in addition to their participation in the main study.
