The purpose of this study is to better understand genetic susceptibility to infections and the interactions of specific genetic polymorphisms of innate immune receptors with microbial and fungal organisms. The goals of this study are: 1. Find out if some people are more likely to get severe infections, than others. To do this we will compare patients with leukemia who develop severe infections to patients who do not develop infections. 2. Find out if some people are more likely to develop lymphoma than others. To do this we will compare patients with lymphoma to people without lymphoma who are of the same sex and similar age and ethnic background to the patients with lymphoma.
Short-daily hemodialysis is increasingly becoming a preferred alternative to the conventional intermittent (three times per week) hemodialysis schedule. Studies have shown that short-daily dialysis improves a patient's quality of life, high blood pressure, anemia and calcium-phosphorus balance. Infection, however, will likely remain a persistent problem for dialysis patients regardless of the frequency of treatments. There is currently a wealth of information to guide doctors on how much and how frequently to give an antibiotic for patients who receive intermittent (thrice weekly) hemodialysis. However, there is very little information on how to prescribe antibiotics for patient's receiving short-daily hemodialysis. This study will develop drug dose guidelines for patients receiving short-daily hemodialysis for three frequently used antibiotics, vancomycin, levofloxacin and gentamicin. These guidelines will assist doctors so that patients receive the most effective dose and frequency of an antibiotic to treat their infection. The following is the study hypothesis which will be tested with two-sided, one sample t-tests comparing the AUC observed to historical measures8. 1) Vancomycin, levofloxacin and gentamicin are removed to a greater extent by short-daily hemodialysis than intermittent hemodialysis. The following are the specific aims: 1. Determine the interdialytic pharmacokinetics of vancomycin, gentamicin, and levofloxacin by short-daily HD. 2. Determine the extent of vancomycin removal when administered during the last hour of short-daily HD. 3. Develop drug-dosing guidelines for vancomycin, gentamicin and levofloxacin for patients receiving short-daily HD.
The objective of the study is to compare two different doses of Peg-INF-α-2A (90 or 180 ug/wk) for their ability to maintain viral control when initiated 5 weeks before ART (antiretroviral therapy) interruption in HIV positive, ART-suppressed subjects (viral load <50 copies/ml) as determined by observing the percentages of viral load measurements <400 copies/ml between the two arms over a 24-week period, corresponding to the Pegasys monotherapy period (exclusive of dual ART/Pegasys 5-week period). Primary analysis will be an "intent to treat" analysis and will address the hypothesis that two different doses of Peg-INF-α-2A (90 and 180 ug/week) will be similarly effective at inhibiting viral replication.
In this project we will study the capacity for single nucleotide polymorphisms (SNP) in TLR4 gene to induce varying levels of inflammatory chemokine and cytokine production.
The purpose of this proposal is clinical validation of an electrochemical biochip for rapid pathogen identification and antibiotic susceptibility determination.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus, sirolimus, antithymocyte globulin, and methotrexate before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well sirolimus, tacrolimus, and antithymocyte globulin work in preventing graft-versus-host disease in patients undergoing a donor stem cell transplant for hematological cancer .
The primary objective of this study is to determine the incidence of severe RSV LRTI requiring hospitalization among infants born < 35 weeks gestational age for one year of follow-up.
