Filter by:Voriconazole (VCZ), the antifungal drug active against Candida and Aspergillus is a substrate of CYP2C19, whose proportion of poor metabolizers is about ~20% in Asian population. The AUC's of VCZ differs over 4 folds by CYP2C19 genotypes of homozygotic wild type, heterozygote, and homozygotic poor metabolizers. The Asian population enrolled in the metabolism of VCZ were mainly Japanese and Chinese, without Korean subjects. The proportion of poor metabolizers in Korean population is known to be around 12% (Pharmacogenetics. 1996 Dec;6(6):547-51). The importance of CYP2C19 genotypes on the pharmacokinetics (PK) of voriconazole is well established, Hence, it is desirable to individualize the dosage regimen of VCZ according to the genotypes of patients. Fungal infection in immunocompromised patients is a life threatening condition which needs critical care. Although the PK change by genotypes are well known, its clinical implication or need for different dosage regimen by genotypes is not established, yet.
This study will examine the effectiveness of a new laboratory method for detecting pneumocystis organisms in a salt-water (saline) oral wash. Pneumocystis infection in people with weakened immunity especially patients with HIV infection or cancer, organ transplant recipients and people receiving immune suppressing therapy can cause life-threatening pneumonia. Currently, pneumocystis infection is diagnosed by sputum analysis or bronchoalveolar lavage. For the sputum analysis, patients are induced to produce a sputum sample (liquid discharge from the lung) using a saline mist; however, many hospitals lack the expertise to perform this procedure. The second method, bronchoalveolar lavage, involves inserting a flexible tube into the lung and injecting saline to produce a specimen for diagnosis. This method, however, is time-consuming and can be uncomfortable. New techniques may allow the use of an oral wash to diagnose pneumocystis, even though an oral sample contains far fewer organisms than are obtained with the current methods. This study will examine whether new techniques, such as nucleic acid amplification, may enable a simple oral wash to be used effectively for diagnosis of pneumocystis infection. Patients 3 years of age and older with weakened immunity who have acute pneumonia may be eligible for this study. In addition, people at increased risk of infection with pneumocystis, including health care professionals, family members of patients, and other patients in health care facilities, may participate. Participants will have a medical history and review of medical records to determine their health status and determine if they have had recent respiratory problems or documented PCP. They will then provide an oral wash sample. For this procedure, subjects first rinse their mouth well. Then, they vigorously swish 50 milliliters of saline for 5 to 10 seconds and immediately repeat the procedure to provide two specimens. Washes may be requested daily, weekly, monthly, or for a period of time to be specified. Participants will also have two tubes of blood drawn (total of 20 milliliters, or 4 teaspoons) to test for evidence of pneumocystis. Although no other tests are required for this protocol, participants may be asked to provide optional add'l samples, as follows: If a sputum or bronchoalveolar lavage sample is required in the course of the patient s clinical mgmt, enough material will be obtained, if possible, for research purposes as well as what is needed for routine care. An induced sputum sample may be requested just for this protocol. For this procedure, a mask with a saline mist is placed over the face, inducing a cough that, it is hoped, will produce sputum from the lungs....
This is a non-comparative, open, multisite prospective estimation study to evaluate the efficacy and safety of caspofungin in the prophylactic treatment of adults who have received an orthotopic liver transplant and are at high risk of developing an invasive fungal infection. It is expected that the proportion of high-risk liver transplant recipients who develop a documented (proven or probable per European Organization for Research and Treatment of Cancer/Mycoses Study Group [EORTC/MSG] modified criteria) invasive fungal infection during the first 100 days after the onset of prophylaxis with caspofungin will be lower than 15%. It is also expected that the incidence of serious drug-related adverse events will be less than 25%.
This is a tissue, urine, and blood banking protocol for cutaneous t-cell lymphoma (CTCL), eczema, and atopic dermatitis patients for current and future research.
The investigators designed a compassionate basis phase II study for refractory/relapsed mycosis fungoides/Sezary syndrome consisting of alemtuzumab (Campath) for primary evaluation of overall response and time to relapse. Other goals to consider are toxicity and time to new therapy.
