Active clinical trials for "Mycoses"

The purpose of this study is to try to find out how critically ill patients receiving the anti fungal medication, posaconazole, process it in their body. Investigators would like to study if the recommended doses of posaconazole achieve adequate concentrations in the patients blood to treat fungal infections.The disease process in critically ill patients can profoundly influence the concentration of anti fungal medication in the blood. The process by which a drug travels through the body in blood, how it is broken down and removed by the body is called pharmacokinetics (PK). This information is important to know because if antifungal levels are low in the blood, the fungal infection has an opportunity to become resistant to the antifungal medication which can lead to the medication being less effective against the fungal infection potentially exposing future patients with infection to a limited range of effective antifungals. Investigators can measure the PK by taking blood samples at specific times after the anti fungal medication is given. This study will enroll 8 patients who are admitted to the intensive care unit and are being treated with an antifungal medication for a fungal infection. Patients will be consented and given a single dose of posaconazole and serial blood samples will be collected just prior to the dose and at 15, 45,75 minutes during the infusion and at 3, 5, 8, 12, 18, 24, 30 36 and 48 hours . Information about the patients stay in the ICU will also be collected including blood pressure, temperature, blood test results.

This randomized phase III trial studies how well levofloxacin works in preventing infection in young patients with acute leukemia receiving chemotherapy or undergoing stem cell transplant. Giving antibiotics may be effective in preventing or controlling early infection in patients receiving chemotherapy or undergoing stem cell transplant for acute leukemia. It is not yet known whether levofloxacin is effective in preventing infection.

This randomized phase III trial studies how well caspofungin acetate works compared to fluconazole or voriconazole in preventing fungal infections in patients following donor stem cell transplant. Caspofungin acetate, fluconazole, and voriconazole may be effective in preventing fungal infections in patients following donor stem cell transplant. It is not yet known whether caspofungin acetate is more effective than fluconazole or voriconazole in preventing fungal infections in patients following donor stem cell transplant.

This study will examine the phototoxicity, a reaction to light that is like exaggerated sunburn, which occurs in people who take medications such as voriconazole, a medication used to fight fungus. Sunscreens might protect the skin from the reaction. Although phototoxicity from voriconazole is not completely understood, it may be related to how that medication is metabolized in the liver by enzymes called cytochrome P450 enzymes-and mainly by one known as 2C19. A way to evaluate phototoxicity is through microarrays, which measure how much each gene is expressed in cells from tissues such as skin. Patients ages 8 and older who are scheduled to begin taking or who currently take voriconazole may be eligible for this study. Also, patients ages 18 to 45 in good health who have skin tone known as Type 2, which usually burns and tans only slightly following sun exposure, may be eligible. All patients will visit the Dermatology Clinic. They will complete two questionnaires, on medical history and medications, as well as the skin response to sunlight, and donate about 3 teaspoons of blood. Patients who are scheduled to take voriconazole will visit the clinic four times, that is, two visits 2 consecutive days before beginning the medication and two visits on 2 consecutive days after taking it for at least 7 days. Each visit will take 1 to 2 hours. Patients about to take voriconazole will have a blood test and undergo a physical exam of the skin test site, on the buttocks. Researchers will take photographs of the specific site and do tests to measure skin reaction to ultraviolet (UV) light. UV light will be shined on 15 small areas of the skin, each 1 x 1 centimeters. After 24 hours, any redness that occurs on the skin will be checked. Afterward, patients will begin taking voriconazole according to directions by the researchers. At 10 or more days later, patients will visit the clinic. Sunscreen will be applied and 1 hour later after administration of voriconazole, a blood sample will be drawn to check the level of medication. Then UV light will be shined on 23 areas of skin 1 x 1 centimeters. More photographs will be taken of test sites to record changes in skin redness. On the next day, the skin response will be evaluated. Participants in the control group will be asked to avoid UV radiation by wearing hats and clothing, and using sunscreen. They will be given the doxycycline, an antibiotic, and undergo procedures with UV light shined on small areas of the skin, on the buttocks. Control participants will have 7 study days, with visits lasting from 1 to 3 hours and probably not exceeding 8 hours. They will have two shave biopsies on Study Day 2 and on Study Day 7 to determine how the skin has responded to UV light exposures. ...

RATIONALE: Voriconazole may be effective in preventing systemic fungal infections following chemotherapy. PURPOSE: Phase II trial to study the effectiveness of voriconazole in preventing systemic fungal infections in children who have neutropenia after receiving chemotherapy for leukemia, lymphoma, or aplastic anemia or in preparation for bone marrow or stem cell transplantation.

In the proposed study, NM-IL-12 will be evaluated as immunotherapy to increase antitumor efficacy against CTCL, while reducing skin-related toxicity, when combined with low-dose TSEBT therapy. Determination of the maximum tolerated dose (MTD) for NM-IL-12 is not planned in this study, rather, a pre-defined starting dose will be explored; this dose is based on two safety and tolerability studies of NM-IL-12 in healthy volunteers.

This is a multi-center, prospective, open, observational and optimal clinical research to evaluate the clinical effectiveness and safety of different doses of micafungin sodium for injection in patients with hematological tumors.

Epstein Barr Virus (EBV) or Cytomegalovirus (CMV) infection results in significant morbidity and mortality in hematopoietic stem cell transplantation (HSCT) patients. HSCT patients often face opportunistic infections due to the immunosuppressive state during transplantation. Antimicrobial drugs are usually used for prophylactic purposes and for treatment after early detectable infections. Unfortunately, some patients develop resistance to such drug treatment. In addition to HSCT patient, immune compromised patient may also be victim to opportunistic infections. Many infections can be effectively managed by functional immune recovery. In this study, the safety and efficacy of microbial-specific cytotoxic T lymphocytes (CTLs) will be investigated.

Patients with cutaneous CD30 positive lymphoma will receive systemical and topical treatment with their own genetically modified T cells. Treatment evaluation consists of assessment of safety and preliminary evidence of response.

Recruitment of at least 10 adult patients (men and women) among individuals affected and admitted to the hospitals identified for the clinical study. All patients shall be between 18 and 75 years of age, with confirmed diagnosis of cryptococcosis or aspergillosis . During therapy (14 days) and examination (28 days), the patients will be subject to 7 doctor's visits (day 1,3,7,10,14,21, and 28).
