Pharmacokinetics, Safety, and Tolerability of Intravenous Posaconazole Solution Followed by Oral...
Fungal InfectionThe purpose of this study is to collect pharmacokinetic (PK) information related to how well intravenous Posaconazole (POS IV), is distributed in the body and to determine the safety and tolerability of this new formulation. In addition, the PK, safety, and tolerability of switching from taking POS IV to taking Posaconazole Oral Suspension (POS Oral) will be evaluated. The data collected in this study will be compared to data collected in previous studies. Individuals who have been diagnosed by their physicians with a blood disease or cancer that can affect their infection-fighting white blood cells will be asked to participate in the trial. Since these blood diseases and their treatments can weaken the immune system, they may put these individuals at a high risk for getting a serious fungal infection of their internal organs or blood (invasive fungal infection). As these fungal infections can be hard to detect early and can be life-threatening, many physicians believe that individuals diagnosed with these diseases should receive antifungal therapy to try to lower their risk of getting this type of infection. Enrollment into this study will take place in several stages (cohorts). The determination of which cohort an individual will be asked to participate in is based on which cohort is open at the site at the time the individual is approached to consider study participation.

Invasive CandidiasesInvasive fungal infection is detecting candida species in blood, cerebrospinal fluid, or urine. Clinical signs of invasive candidiasis may include lethargy, temperature instability, feeding intolerance, apnea, hypotension, respiratory distress, abdominal distension, and thrombocytopenia. Fungal infection has been associated with an increased risk of retinopathy of prematurity and chronic lung disease. Preterm and low birth weight infants have an immature immune system that predisposes them to infections with bacteria, viruses, and fungi. These infants usually require prolonged admission in the neonatal unit and there is often a need for the administration of broad-spectrum antibiotics which predisposes them to colonization with fungi that may invade to cause systemic disease8. Other risk factors for the development of invasive fungal infection include endotracheal intubation, abdominal surgery, the presence of a central venous catheter, administration of H2 antagonists, and steroids. Infection with Candida species is the third most common cause of bloodstream infection in premature infants. Mortality in preterm infants due to invasive candidiasis is around 20% and can be as high as 50% in infants weighing <1500g at birth. Invasive candidiasis is the second most common infectious cause of death in extremely preterm infants. The present study was conducted to determine the incidence of invasive candidiasis among preterm and very low birth weight infants in our neonatal unit and to evaluate the efficacy of prophylactic fluconazole in preventing invasive fungal infection. Based on the results of the present study institutional guidelines may be designed in our neonatal unit relating to antifungal prophylaxis in preterm and very low birth weight infants.
Comparison of Two Treatments to Prevent Invasive Fungal Infections in Patients Who Have Received...
CandidiasisThe purpose of this study is to compare the safety and effectiveness of 2 treatments to prevent invasive fungal infections (IFI), which are infections caused by yeasts and molds that are common in patients with weak immune systems or transplant patients. AmBisome, a new treatment, will be compared to fluconazole, the traditional treatment for fungal infections caused by the yeast Candida. Treatment will only be given to liver transplant patients who are found to be at high risk for IFI. Liver transplant patients who are at low risk for IFI will be monitored but will receive no study medication. IFIs are found mainly in a high risk group of liver transplant patients, and are not common in those with low risk. If IFI preventive therapy is focused on the high risk group, there may be a lesser chance of Candida becoming resistant (able to grow despite the presence of drugs used to kill it). Treating only the high risk group will also save money.
Efficacy of Itraconazole as Secondary Prophylaxis in Patients Undergoing Allogeneic Stem Cell Transplantation...
Invasive Fungal InfectionInvasive fungal infections (IFI) remain the major cause of death among neutropenic patients receiving chemotherapy for leukemia, or submitted to stem cell transplantation. Patients with a history of invasive fungal infection (IFI) are at high risk of developing relapse and fatal complications. Prompt intensive antifungal therapy, have improved responses and survival, allowing an increase of antifungal treatments, including secondary antifungal prophylaxis. Few studies have addressed the role of previous IFI in the feasibility of stem cell transplant, or the secondary prophylaxis with antifungal drugs in preventing recurrence of infection after transplantation. However, given the lack of prospective studies, the role of secondary antifungal prophylaxis remains unclear. Itraconazole is a wide-spectrum triazole antifungal agent active against Candida albicans, non-albicans, Aspergillus spp., Blastomyces dermatitidis, Blastomyces coccidioides, Cryptococcus neoformans, Sporothrix schenkii, Paracoccidioides brasiliensis, Histoplasma spp. and various kinds of yeast fungi and mycetes. The role of itraconazole IFI prophylaxis treatment has been proved by many interventional studies. In this prospective, multicentric study of secondary prophylaxis, itraconazole will be given at standard dose to patients undergoing allogeneic stem cell transplantation or chemotherapy with prior invasive fungal infection, to assess the efficacy and safety of itraconazole secondary prophylaxis.
Liposomal Amphotericin B (Ambisome) Versus Oral Voriconazole for the Prevention of Invasive Fungal...
Acute Myelogenous LeukemiaMyelodysplastic SyndromeThe goal of this clinical research study is to compare the effectiveness of liposomal amphotericin B given three times per week , versus liposomal amphotericin B given once per week, versus oral voriconazole in the prevention of fungal infections in patients with acute myeloid leukemia (AML) or myelodysplastic syndromes MDS who are receiving chemotherapy. The safety of these treatments will also be studied and compared.
