BACKGROUND Patients with neutropenia and persistent fever are often treated empirically with amphotericin B or liposomal amphotericin B to prevent invasive fungal infections. Antifungal triazoles offer a potentially safer and effective alternative. METHODS In a randomized, international, multicenter trial, we compared voriconazole, a new second-generation(More)
The study presented here was performed in order to create a rule that identifies subjects at high risk for invasive candidiasis in the intensive care setting. Retrospective review and statistical modelling were carried out on 2,890 patients who stayed at least 4 days in nine hospitals in the USA and Brazil; the overall incidence of invasive candidiasis in(More)
BACKGROUND Patients with persistent fever and neutropenia often receive empirical therapy with conventional or liposomal amphotericin B for the prevention and early treatment of invasive fungal infections. Caspofungin, a member of the new echinocandin class of compounds, may be an effective alternative that is better tolerated than amphotericin B. METHODS(More)
BACKGROUND Invasive aspergillosis is an important cause of morbidity and mortality in immunocompromised patients. Current treatments provide limited benefit. Posaconazole is an extended-spectrum triazole with in vitro and in vivo activity against Aspergillus species. METHODS We investigated the efficacy and safety of posaconazole oral suspension (800(More)
Cunninghamella bertholletiae shares many of the features typical of the other agents causing zygomycoses. Those who are immunocompromised constitute the major patient population at risk; the agents as a group are aggressive, the disease is often disseminated, and the pathologic picture of vascular invasion and tissue infarction is common. Unlike other(More)
We investigated the clinical characteristics and treatment of patients with a distinctive triad of acute infusion-related reactions (AIRRs) to liposomal amphotericin B (L-AMB) via single-center and multicenter analyses. AIRRs occurred alone or in combination within 1 of 3 symptom complexes: (1) chest pain, dyspnea, and hypoxia; (2) severe abdomen, flank, or(More)
In a double blind study, oral prophylactic trimethoprim/sulfamethoxazole was evaluated for its utility in preventing serious infections in patients with hematologic malignancy. Of 58 evaluated granulocytopenic episodes in 47 patients, acute leukemia was the underlying malignancy in 46 episodes. Trimethoprim/sulfamethoxazole prophylaxis resulted in fewer(More)
Community-acquired pneumonia remains an important infectious disease problem, with more than 4 million cases occurring in the United States annually. Although Streptococcus pneumoniae remains the most commonly identified organism, a variety of bacterial and nonbacterial pathogens may be involved. Hospitalization is unnecessary in most cases, and oral(More)
Fever in the compromised host remains a significant clinical problem. Multiple potential pathogens, subtle physical findings, and a variety of noninfectious problems that may masquerade as infection contribute to this clinical challenge. A review of host defense defects along with a careful physical examination will begin to narrow the etiologic(More)
Adults with chronic granulomatous disease of childhood (CGD) have been described who remain relatively free of infection despite markedly abnormal neutrophil function. Monocyte function in four adults with this mild or atypical CGD syndrome was examined and compared to that of normal controls and to that of two patients with the more severe or classic CGD(More)
