In total, 161 Candida isolates were detected among 147 of the 331 patients (44%), independently of the time when HIV infection was diagnosed. Candida albicans strains represented 137 (85%) of the isolates, and were susceptible to all of the tested antifungal drugs. Among the non-C. albicans strains, six isolates were dose-dependently susceptible to fluconazole, nine to itraconazole, Rigosertib inhibitor and seven to ketoconazole. The isolation of Candida was significantly higher in patients with virological failure (83/147; p 0.0002) and CD4(+) T-lymphocyte counts < 200 cells/mm(3) (30/83; p 0.0003). Recovery of Candida in the oral cavity was independent of protease inhibitor (PI) usage (p 0.60). Colonized patients typically
underwent salvage therapy (p 0.003), and
had more episodes of opportunistic fungal infections (p 0.046) and malignancies (p 0.004). BIIB057 concentration Oral Candida colonization in patients under ARV therapy was associated with the immunosupressed status of HIV-infected patients, i.e. low number of CD4(+) T-cells per cubic millimetre, failure of ARV therapy (salvage therapy), and higher number of opportunistic infections and malignancies. Despite the fact that PIs have in vitro antifungal activity, the use of this class of antiretroviral agent did not influence the presence of Candida in the oral cavity of AIDS patients.”
“Study Design. A retrospective longitudinal observational study using baseline and follow-up magnetic resonance imaging (MRI).
Objective. To study the natural history
of disc degeneration, focusing on the significance of changes affecting the individual components of the intervertebral disc.
Summary of Background Data. The natural history of the degenerative disc disease is poorly understood. Focusing on the relative prevalence, temporal evolution, and interactions of pathology in the anulus fibrosus, nucleus pulposus, and the end plates can help in better understanding of this process.
Methods. MRIs of the lumbar spine in 63 patients, obtained at a mean interval of 30 months, were evaluated independently by two neuroradiologists to assess the temporal evolution of degeneration changes in 378 discs between T12 through S1 segments. In addition, a direct side-by-side comparison of two studies was also performed. Statistical analysis was performed to assess the association PLK inhibitor between the degeneration of individual disc components and to find the predictors of future degeneration.
Results. Radial anular tears and end plate defects were associated with worse nuclear degeneration at the time of the initial study. Both end plate defects and nuclear degeneration were rare in the absence of radial tears. Multiple nominal logistic regression analysis showed that radial tears and herniation at the time of the initial study, along with the duration between the two imaging studies were the significant predictors of worsening nuclear degeneration.
