A nursing sister developed Australia-antigen-positive hepatitis 101 days after the blood of an Australia-antigen-positive patient was accidentally introduced into her eye. There may be important implications for those caring for patients with Australia-antigenemia or undertaking laboratory investigations on their blood.
polyarteritis nodosa is a multisystem necrotizing vasculitis of small and medium size muscular arteries in which involvement of the renal and viserat arteries is characteristic. the etiology is unknown but hepatitis b antigenemia is found in 30% of patients. drug exposures and hypersensitivity reactions are other possible causes. excellent therapeutic results have been reported in classic polya...
BACKGROUND The performance of serum biomarkers for the early detection of invasive aspergillosis expectedly depends on the timing of test results relative to the empirical administration of antifungal therapy during neutropenia, although a dynamic evaluation framework is lacking. METHODS We developed a multi-state model describing simultaneously the likelihood of empirical antifungal therapy ...
Temozolomide chemotherapy has become part of the therapy used to treat glioblastoma multiforme and refractory anaplastic astrocytoma. Temozolomide frequently produces profound lymphopenia. We report 2 cases of cytomegalovirus disease that occurred in patients receiving temozolomide therapy and review 4 additional cases reported in the literature. Narrow monitoring with cytomegalovirus antigenem...
Fatal empyema thoracis caused by Schizophyllum commune with cross-reactive cryptococcal antigenemia.
We report a fatal case of Schizophyllum commune empyema thoracis with cross-reactive cryptococcal antigenemia. In vitro testing confirmed the ability of the fungus to cause a positive cryptococcal antigen latex agglutination system (CALAS) test result. Such a result may lead to delay in diagnosis and treatment, as most strains of S. commune are resistant to fluconazole.
OBJECTIVES The present study aimed to evaluate the dynamics of CD28 and CD57 expression in CD8+ T lymphocytes during cytomegalovirus viremia in bone marrow transplant recipients. METHODS In a prospective study, blood samples were obtained once weekly once from 33 healthy volunteers and weekly from 33 patients. To evaluate the expression of CD57 and CD28 on CD8+ T lymphocytes, flow cytometry a...
A quantitation procedure for hepatitis B core antigen (HBcAg) in serum without prior removal of antibodies to HBcAg is described. The virus nucleoprotein core was released from hepatitis B virus (HBV) particles by treatment with Nonidet P-40 detergent and allowed to form immune complexes with homologous antibodies to HBcAg present in the sera of HBV-infected individuals. After precipitation wit...
BACKGROUND AND OBJECTIVES Although alemtuzumab (campath-1H) has been successfully used in patients with untreated or previously treated chronic lymphocytic leukemia (CLL), a variable incidence of cytomegalovirus (CMV) reactivation has been described. No prospective reports currently provide results of the use of oral ganciclovir as pre-emptive therapy in patients with CMV reactivation during al...
Development of an inhalational Bacillus anthracis exposure therapeutic model in cynomolgus macaques.
Appropriate animal models are required to test medical countermeasures to bioterrorist threats. To that end, we characterized a nonhuman primate (NHP) inhalational anthrax therapeutic model for use in testing anthrax therapeutic medical countermeasures according to the U.S. Food and Drug Administration Animal Rule. A clinical profile was recorded for each NHP exposed to a lethal dose of Bacillu...
The current strategy for interrupting transmission of lymphatic filariasis (LF) is annual mass drug administration (MDA), at good coverage, for 6 or more years. We describe our programmatic experience delivering the MDA combination of ivermectin and albendazole in Plateau and Nasarawa states in central Nigeria, where LF is caused by anopheline transmitted Wuchereria bancrofti. Baseline LF mappi...
