Vacuum assisted vegetation extraction for the management of large lead vegetations.

BACKGROUND: Complete device and lead removal is recommended for management of infected implantable cardiac device. Management of large lead vegetation (2 cm) is still in debate. METHODS: We report a series of patients involving percutaneous extraction of large vegetations (>2 cm) from ICD/pacing leads using the AngioVac Cannula in patients with infective endocarditis. This approach was used to debulk the ICD/pacing lead vegetations in order to minimize the risk of septic pulmonary embolism during lead explantation. CONCLUSION: AngioVac Cannula can be used safely and effectively as an adjunct

Early and late markers for the detection of early-onset neonatal sepsis.

INTRODUCTION: In this study we tested how a combination of early and late paraclinic markers could predict early onset neonatal sepsis (EONS). METHODOLOGY: The first 24 hours after the suspicion of EONS, we measured interleukine (IL)-6, IL-8, IL-10, IL-18, tumor necrosis factor-alpha (TNF-alpha), interferon gamma (INF-gamma), procalcitonin (PCT) and C-reactive protein (CRP) at 8-hour intervals on 123 neonates clinically suspected for EONS. The neonates were divided into two groups. The sepsis group: 1A with blood culture verified bacteraemia and 1B strongly suspected sepsis (29 patients). The

Dual role of TLR2 and myeloid differentiation factor 88 in a mouse model of invasive group B streptococcal disease.

Toll-like receptors (TLRs) are involved in pathogen recognition by the innate immune system. Different TLRs and the adaptor molecule myeloid differentiation factor 88 (MyD88) were previously shown to mediate in vitro cell activation induced by group B streptococcus (GBS). The present study examined the potential in vivo roles of TLR2 and MyD88 during infection with GBS. When pups were infected locally with a low bacterial dose, none of the TLR2- or MyD88-deficient mice, but all of the wild-type ones, were able to prevent systemic spread of GBS from the initial focus. Bacterial burden was highe

Prevention of perinatal group B streptococcal disease: updated CDC guideline.

Group B streptococcus is the leading cause of early-onset neonatal sepsis in the United States. Universal screening is recommended for pregnant women at 35 to 37 weeks' gestation. The Centers for Disease Control and Prevention recently updated its guideline for the prevention of early-onset neonatal group B streptococcal disease. The new guideline contains six important changes. First, there is a recommendation to consider using sensitive nucleic acid amplification tests, rather than just routine cultures, for detection of group B streptococcus in rectal and vaginal specimens. Second, the colo

Purulent pericarditis: report of 2 cases and review of the literature.

Purulent pericarditis, a localized infection within the pericardial space, has become a rare entity in the modern antibiotic era. Although historically a disease of children and young adults, this is no longer the case: the median age at the time of diagnosis has increased by nearly 30 years over the past 6 decades. Despite advances in diagnostic and treatment modalities, purulent pericarditis remains a life-threatening illness. Unfortunately, the diagnosis is made postmortem in more than half the cases. Thus, a high index of clinical suspicion is crucial. We present 2 cases of purulent perica

Reducing atelectasis attenuates bacterial growth and translocation in experimental pneumonia.

Besides being one of the mechanisms responsible for ventilator-induced lung injury, atelectasis also seems to aggravate the course of experimental pneumonia. In this study, we examined the effect of reducing the degree of atelectasis by natural modified surfactant and/or open lung ventilation on bacterial growth and translocation in a piglet model of Group B streptococcal pneumonia. After creating surfactant deficiency by whole lung lavage, intratracheal instillation of bacteria induced severe pneumonia with bacterial translocation into the blood stream, resulting in a mortality rate of almost

Activation of the NLRP3 inflammasome by group B streptococci.

Group B Streptococcus (GBS) is a frequent agent of life-threatening sepsis and meningitis in neonates and adults with predisposing conditions. We tested the hypothesis that activation of the inflammasome, an inflammatory signaling complex, is involved in host defenses against this pathogen. We show in this study that murine bone marrow-derived conventional dendritic cells responded to GBS by secreting IL-1β and IL-18. IL-1β release required both pro-IL-1β transcription and caspase-1-dependent proteolytic cleavage of intracellular pro-IL-1β. Dendritic cells lacking the TLR adaptor MyD88, but no

sCD25 as an independent adverse prognostic factor in adult patients with HLH: results of a multicenter retrospective study.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but often fatal hyperinflammatory syndrome caused by an inborn or acquired error of immunity. In adults, the underlying immunodeficiency generally arises alongside severe infections, malignancies, autoimmune diseases, and immunosuppressive treatment. To analyze risk factors and outcome in adults, we conducted a multicenter retrospective study. A total of 62 adult (age ≥18 years) patients met at least one of the following inclusion criteria: (1) ≥5 of 8 HLH-2004 criteria, (2) HScore ≥ 200 plus 4 HLH-2004 criteria, or (3) mutation compatible wit

This study uses in vitro assays and a mouse model to investigate antibacterial properties of ticagrelor to follow up findings from 2 clinical trials that showed patients taking ticagrelor for cardiovascular disease had a lower risk of infection-related death and improved lung function compared with patients treated with clopidogrel.

Novel engagement of CD14 and multiple toll-like receptors by group B streptococci.

Group B streptococcus (GBS) imposes a major health threat to newborn infants. Little is known about the molecular basis of GBS-induced sepsis. Both heat-inactivated whole GBS bacteria and a heat-labile soluble factor released by GBS during growth (GBS-F) induce nuclear translocation of NF-kappaB, the secretion of TNF-alpha, and the formation of NO in mouse macrophages. Macrophages from mice with a targeted disruption of MyD88 failed to secrete TNF-alpha in response to both heat-inactivated whole bacteria and GBS-F, suggesting that Toll-like receptors (TLRs) are involved in different aspects of

Increasing Gram-Negative Catheter-Related Bloodstream Infection in Cancer Patients.

Background: We aimed to assess the incidence, etiology and outcomes of catheter-related bloodstream infection (CRBSI) in onco-hematological patients, to assess the differences between patients with hematological malignancies (HMs) and solid tumors (STs) and to identify the risk factors for Gram-negative (GN) CRBSI. Methods: All consecutive episodes of BSI in adult cancer patients were prospectively collected (2006-2020). The etiology of CRBSI was analyzed in three different 5-year periods. Risk factors for GN CRBSI were assessed in the whole cohort and separately in patients with HMs and STs.
