Coagulative Biomarkers Differently Predict Clinical Outcomes in Invasive Infections Caused by Neisseria Meningitidis and Streptococcus Pneumoniae.

Background: Coagulation plays a crucial role in innate immune response to invasive infections. Coagulative biomarkers might predict clinical outcomes differently, depending on etiology.

Methods: A retrospective study was conducted during a 79-month period, recruiting 90 patients with meningitis or bloodstream infection caused by Neisseria meningitidis (n = 47) or Streptococcus pneumoniae (n = 43), median age 19 and 58 years, respectively.

Safety and Efficacy of a Single Procedure of Extraction and Reimplantation of Infected Cardiovascular Implantable Electronic Device (CIED) in Comparison with Deferral Timing: An Observational Retrospective Multicentric Study.

(1) Background: Infections are among the most frequent and life-threatening complications of cardiovascular implantable electronic device (CIED) implantation. The aim of this study is to compare the outcome and safety of a single-procedure device extraction and contralateral implantation versus the standard-of-care (SoC) two-stage replacement for infected CIEDs. (2) Methods: We retrospectively included 66 patients with CIED infections who were treated at two Italian hospitals.

Pragmatic overview on acute bacterial and fungal infections of the central nervous system: a holistic update from diagnosis to treatment.

Although progress has led to a drop in infections, meningitis still represents a threat worldwide, affecting some areas more than others. As a medical emergency, it requires prompt recognition and treatment. Moreover, diagnosis relies on invasive methods, while representing a tug-of-war with timely therapeutic interventions, since delays are burdened by mortality and life-long sequalae.

D-Dimer as Biomarker for Early Prediction of Clinical Outcomes in Patients With Severe Invasive Infections Due to and .

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection; no current clinical measure adequately reflects the concept of dysregulated response. Coagulation plays a pivotal role in the normal response to pathogens (immunothrombosis), thus the evolution toward sepsis-induced coagulopathy could be individuate through coagulation/fibrinolysis-related biomarkers. We focused on the role of D-dimer assessed within 24 h after admission in predicting clinical outcomes in a cohort of 270 patients hospitalized in a 79 months period for meningitis and/or bloodstream infections due to ( = 162) or ( = 108).

Candida palmioleophila isolation in Italy from two cases of systemic infection, after a CHROMagar and Vitek system mis-identification as C. albicans.

A correct, fast, reliable identification method is pivotal in nosocomial environments to guide treatment strategies, whereas misidentification might lead to treatment failure. For routine identifications the Vitek system and CHROMagar are widely used but not always reliable, especially now with an increasing number of new emerging fungal pathogens that need careful identification. Here we describe two cases of candidemia, due to Candida palmioleophila previously misidentified as Candida albicans by using the Vitek2 system and CHROMagar.

Procalcitonin, white blood cell count and C-reactive protein as predictors of S. aureus infection and mortality in infective endocarditis.

Background: Infective endocarditis (IE) is characterized by high rates of in-hospital death, and Staphylococcus aureus infection predicts a worse prognosis. We aimed to assess if admission inflammatory biomarkers (white blood cell - WBC - count, C-reactive protein - CRP, and procalcitonin) are informative on microbiological etiology and short-term outcomes.

Methods: Data from 236 patients admitted for IE from January 2013 to June 2018 were retrieved from a multicenter registry.

Ceftobiprole for the treatment of infective endocarditis: A case series.

Objectives: Ceftobiprole is a relatively new cephalosporin with broad-spectrum activity and good tolerability. Despite its promising characteristics, to our knowledge, only two case reports, previously published also by some of us, is available concerning its administration for the treatment of infective endocarditis. Hereby we report our experience in this field.

Breakthrough pneumonia, meningitis and bloodstream infection due to during cefixime therapy.

is the main pathogen in invasive, life-threatening diseases such as bacteremia, meningitis, and pneumonia. We describe three cases of breakthrough pneumococcal severe life-threatening infections, including two meningitis and one bloodstream infection in patients treated with cefixime for otitis, sinusitis and pneumonia, respectively. Cefixime does not seem to be fully effective in treating invasive pneumococcal diseases.

Invasive listeriosis in a patient with several episodes of antibiotic associated colitis presumably due to Clostridium difficile.

A 62-year-old man developed a blood stream infection and meningitis due to Listeria monocytogenes, 20 days after an episode of pseudo-membranous colitis. The patient, hospitalized for the first time for transurethral prostatectomy, was readmitted 20 days later with watery diarrhea. Pseudo-membranous colitis was diagnosed and treated successfully, without testing for Clostridium difficile infection (CDI).

A high PCT level correlates with disease severity in Plasmodium falciparum malaria in children.

Most clinicians in developed countries have limited experience in making clinical assessments of malaria disease severity and/or monitoring high-level parasitemia in febrile patients with imported malaria. Hyperparasitemia is a risk factor for severe P. falciparum malaria, and procalcitonin (PCT) has recently been related to the severity of malaria.

Pneumococcal meningitis in childhood: a longitudinal prospective study.

After implementation of programmes for active immunization against Haemophilus influenzae b, Streptococcus pneumoniae and Neisseria meningitidis became the most common agents of bacterial meningitis in childhood. Over a 9-year period, children showing clinical and laboratory findings of meningitis on the basis of their positive cultures of blood or cerebro-spinal fluid (CSF) for S. pneumoniae were enrolled.

Four cases of meningitis by streptococci other than pneumoniae in adults: clinical and microbiological features.

Meningitis sustained by streptococci other than pneumoniae, infrequent in community medicine, is emerging as a hospital-acquired infection. We describe four cases of meningitis caused by streptococci other than pneumoniae in adults.

Toscana virus central nervous system infections in southern Italy.

Toscana virus was detected by reverse transcription-nested PCR in 5.6% of cerebrospinal fluid (CSF) samples from patients with meningitis and encephalitis during the summer in southern Italy. The central nervous system infections were associated with young adults and with a substantially benign clinical course.

Hepatitis B virus DNA quantitation and detection of core promoter, precore and polymerase mutations in chronic hepatitis B: evaluation and clinical usefulness of three new commercial assays.

Background: HBV-DNA quantitation, the HBe antigen status and the appearance of mutations in the core promoter, precore and polymerase regions are important elements in the management of chronic HBV infection.

Methods: We performed a technical evaluation of 3 new kits, affigene HBV VL, affigene HBV mutant VL and affigene HBV DE/3TC assays (Sangtec Molecular Diagnostics) in comparison with the Amplicor HBV Monitor assay (Manual Test, Roche), direct sequencing and direct sequencing/Inno-LIPA HBV DR (Innogenetics), respectively. We evaluated the clinical application of these tests in the management of patients with chronic (HBeAg positive) hepatitis B.

[Non post-operative spondylodiskitis. Our experience during the period 1990-2001].

Unlabelled: Aim of the study was to evaluate the prevalence and characteristics of non operative spondylodiskitis (SD) in our geographic area.

Methods: We evaluated retrospectively epidemiological, clinical, laboratory and radiological features of patients with non operative SD observed between 1990 and 2001 in our department of the "D. Cotugno" hospital - Naples.
