OBJECTIVES Infections caused by Klebsiella pneumoniae (Kp) carbapenemase (KPC)-producing strains of Kp have become a significant threat in recent years. To assess their outcomes and identify risk factors for 14 day mortality, we conducted a 4 year (2010-13) retrospective cohort study in five large Italian teaching hospitals. METHODS The cohort included(More)
OBJECTIVE To investigate the efficacy and safety of three regimens for primary prophylaxis of Pneumocystis carinii pneumonia (PCP) and toxoplasmic encephalitis (TE) and to evaluate their effect on survival in patients with HIV infection. DESIGN Randomized, open label, prospective trial. SETTING A single Infectious Diseases Department in Italy. (More)
Several methods to increase the sensitivity of JC virus (JCV) DNA detection in cerebrospinal fluid (CSF) for a noninvasive diagnosis of AIDS-related progressive multifocal leukoencephalopathy (PML) were investigated. When CSF collected at clinical presentation was tested, JCV DNA was detected in 8 of 19 patients with PML by standard PCR (sensitivity, 42%;(More)
Fifty-five episodes of Pneumocystis carinii pneumonia (PCP) in AIDS patients were evaluated to assess clinical and laboratory risk factors predicting the probability of surviving the acute episode of PCP and the long-term survival after PCP. Age > 45 yrs, PaO2 < 50 mmHg, AaPO2 > 50 mmHg, and LDH > 800 IU/L correlated strongly with early mortality; patients(More)
OBJECTIVES Biofilm formation (BF) by fungal isolates may dramatically complicate infection. We determined the ability of Candida parapsilosis isolates from single fungaemia episodes to form biofilms and we analysed biofilm subgroups for antifungal susceptibility and pathogenic potential. We then correlated BF with clinical characteristics and outcomes of(More)
DNA amplification by the polymerase chain reaction (PCR) is a promising method for the detection of Pneumocystis carinii in immunosuppressed patients. The sensitivity and specificity of the PCR technique has been assessed in comparison with the immunofluorescence method (IF) on bronchoalveolar lavage fluid (BALF). Results correlated in 43 (78.8%) of 52(More)
The ability of Pneumocystis carinii to induce TNF-alpha release by macrophages from adult healthy humans was investigated. Monocytes and monocytes derived macrophages produced an high amount of TNF-alpha when exposed to P. carinii cysts obtained from rats with steroid induced pneumocystosis. TNF-alpha release was P. carinii specific as shown by the(More)
