The molecular characteristics of the humoral immune response to a serotype A Cryptococcus neoformans infection were compared with the response elicited by a cryptococcal glucuronoxylomannan-tetanus toxoid (GXM-TT) conjugate. Anticryptococcal monoclonal antibodies (mAbs) isolated from both responses have previously been shown to recognize the same antigenic determinant of cryptococcal GXM. South...
Cryptococcosis is a fungal infection caused by Cryptococcus neoformans, generally associated with immunodeficiency and immunosuppressive agents, and it is rarely reported in systemic lupus erythematosus (SLE), particularly in juvenile SLE (JSLE). From January 1983 to June 2011, 5,604 patients were followed at our University Hospital and 283 (5%) of them met the American College of Rheumatology ...
Cryptococcal meningoencephalitis represents a serious infection of the central nervous system, where reliable prognostic factors during the disease course are needed. Twenty-one patients diagnosed with cryptococcal meningoencephalitis in a German university hospital from 1999 to 2013 were analysed retrospectively. CSF parameters were analysed prior to therapy and during antifungal treatment and...
Currently, AIDS represents the most common risk factor for the development of cryptococcosis. Despite of rapid scale-up of antiretroviral therapy programs and global investement in HIV care over the past decade, the decline in incidende and mortality rates associated with cryptococcosis has not been commensurate. This article puts into context recent diagnostics studies and morphologies with sp...
BACKGROUND AND PURPOSE The high rate of neuropsychologic sequelae in CM survivors indicates that initial antifungal therapy is far from being satisfactory. This prospective cross-sectional study applied DTI on HIV-negative CM patients to determine whether microstructural changes in brain tissue are associated with subsequent cognitive symptoms. MATERIALS AND METHODS Fifteen patients with HIV-...
The murine monoclonal antibody (MAb) 18B7 [immunoglobulin G1(kappa)] is in preclinical development for treatment of Cryptococcus neoformans infections. In anticipation of its use in humans, we defined the serological and biological properties of MAb 18B7 in detail. Structural comparison to the related protective MAb 2H1 revealed conservation of the antigen binding site despite several amino aci...
Although T-cell responses are known to be critical for effective host defenses against the fungal pathogen Cryptococcus neoformans, the antigens that stimulate protective responses are poorly characterized but are thought to be comprised, at least in part, of mannoproteins. Recently, we created a panel of murine CD4(+)-T-cell hybridomas that react with C. neoformans antigens. A mannoprotein ant...
Cryptococcosis is a life-threatening fungal infection among human immunodeficiency virus (HIV)-positive patients and also occurs frequently in HIV-negative patients. A retrospective cohort study was conducted among patients with cryptococcosis. Clinical manifestations, laboratory findings, treatment, and outcomes for 149 HIV-positive and 29 HIV-negative patients were compared. Neurological invo...
