Programmed death-1 (PD-1) receptor system represents a part of recently reported immunoregulatory pathway. PD-1 is an immune checkpoint molecule, which plays an important role in downregulating the immune system proinflammatory activity. Until recently, PD-1 expression was not established on immune cells of the preterm infants. The study objectives were to confirm expression of the PD-1 receptors on the monocytes isolated from very low birth weight newborns (VLBW), and to analyze their expression during the first week of life and late-onset sepsis...

BACKGROUND: Inflammasomes regulate activation of caspase-1, which cleaves and activates interleukin (IL)-1β and IL-18, the cytokines that trigger pro-inflammatory and antimicrobial responses. There is very little known about inflammasome function in the subsets of monocytes (MO) isolated from preterm neonates born extremely and very prematurely. METHODS: A group of 76 very low birth weight patients without early-onset sepsis was divided into extremely preterm (<28 gestational week) or very preterm (28-32 gestational week) neonates...

Objectives: To identify the perinatal risk factors for early-onset Group B Streptococcus (EOGBS) sepsis in neonates after inception of a risk-based maternal intrapartum antibiotic prophylaxis strategy in 2004. Design: Case control study. Methods: All newborn with early onset GBS sepsis (born between 2004 and 2013) were deemed to be "cases" and controls were selected in a 1:4 ratio. Results: More than three per vaginal (PV) examinations [odds ratio (OR) 8...

Antimicrobial resistance is an important threat to international health. Therapeutic guidelines for empirical treatment of common life-threatening infections depend on available information regarding microbial aetiology and antimicrobial susceptibility, but sub-Saharan Africa lacks diagnostic capacity and antimicrobial resistance surveillance. We systematically reviewed studies of antimicrobial resistance among children in sub-Saharan Africa since 2005. 18 of 1075 articles reviewed met inclusion criteria, providing data from 67 451 invasive bacterial isolates from inconsistently defined populations in predominantly urban tertiary settings...

AIM: To describe the etiology and characteristics of early-onset conjugated hyperbilirubinemia (ECHB) presenting within 14 d of life in term neonates. METHODS: Retrospective review was performed of term infants up to 28-d-old who presented with conjugated hyperbilirubinemia (CHB) at a tertiary center over a 5-year period from January 2010 to December 2014. CHB is defined as conjugated bilirubin (CB) fraction greater than 15% of total bilirubin and CB greater or equal to 25 μmol/L...

BACKGROUND: Premature infants are at high risk of early-onset sepsis (EOS) relative to term infants, and most are administered empirical antibiotics after birth. We aimed to determine if factors evident at birth could be used to identify premature infants at lower risk of EOS. METHODS: Study infants were born at 22 to 28 weeks' gestation in Neonatal Research Network centers from 2006 to 2014. EOS was defined by isolation of pathogenic species from blood or cerebrospinal fluid culture at ≤72 hours age...

OBJECTIVE: To determine if implementation of a protocol based on a neonatal early-onset sepsis (EOS) calculator developed by Kaiser Permanente would safely reduce antibiotic use in well-appearing term infants born to mothers with chorioamnionitis in the unique setting of an Observation Nursery. STUDY DESIGN: Data obtained from a retrospective chart review of well-appearing term infants born between 2009 and 2016 were entered into the EOS calculator to obtain management recommendations...

BACKGROUND: In the U.S., intrapartum antibiotic prophylaxis (IAP) for pregnant women colonized with group B streptococcus (GBS) has reduced GBS disease in the first week of life (early-onset/EOGBS). Nonetheless, GBS remains a leading cause of neonatal sepsis, including 1000 late-onset (LOGBS) cases annually. A maternal vaccine under development could prevent EOGBS and LOGBS. METHODS: Using a decision-analytic model, we compared the public health impact, costs, and cost-effectiveness of five strategies to prevent GBS disease in infants: (1) no prevention; (2) currently recommended screening/IAP; (3) maternal GBS immunization; (4) maternal immunization with IAP when indicated for unimmunized women; (5) maternal immunization plus screening/IAP for all women...

PURPOSE OF REVIEW: The purpose of this paper is to provide recent insights in management of neurologic complications of left-sided infective endocarditis (IE). RECENT FINDINGS: Cerebral lesions observed in IE patients are thought to involve synergistic pathophysiological mechanisms including thromboembolism, sepsis, meningitis, and small-vessel cerebral vasculitis. Brain MRI represents a major tool for the detection of asymptomatic events occurring in the majority of patients...

BACKGROUND: Neonatal early onset sepsis (EOS) remains an important etiology of neonatal morbidity and mortality. Diagnosis is difficult due to a lack of sensitivity and specificity markers. In France, the management of newborn infants suspected of infection includes the analysis of gastric suction. The objective of the study was to identify early clinical signs in newborn infants with suspected neonatal sepsis to differentiate a likely infection with pathogen bacteria in the gastric suction culture (Streptococcus agalactiae or Escherichia coli) from a possible infection without such pathogen bacteria...

BACKGROUND: Many sepsis survivors develop chronic critical illness (CCI) and are assumed to be immunosuppressed, but there is limited clinical evidence to support this. We sought to determine whether the incidence of secondary infections and immunosuppressive biomarker profiles of patients with CCI differ from those with rapid recovery (RAP) after sepsis. METHODS: This prospective observational study evaluated 88 critically ill patients with sepsis and 20 healthy controls...

BACKGROUND: Sepsis is a commonly encountered and potentially life-threatening problem in neonatal intensive care units, blood culture of neonatal sepsis helps in either optimizing treatment or terminating antibiotics. MATERIALS AND METHODS: We determined the causative agent, time to positivity (TTP), and antibiogram of neonatal blood cultures collected in a tertiary care center, to investigate difference between early- and late-onset neonatal sepsis and to establish the time at which a blood culture could safely be considered negative, using the BacT/ALERT(®) 3D 60...

AIM: To evaluate the incidence, etiology, and predictors of mortality of severe hypoxic hepatitis. METHODS: We used computerized patient records to identify consecutive cases of severe hypoxic hepatitis admitted to a tertiary hospital in Singapore over a one-year period. We defined severe hypoxic hepatitis as elevation of serum transaminases more than 100 times upper limit of normal in the clinical setting of cardiac, circulatory or respiratory failure after exclusion of other causes of hepatitis...

Background/Aims: Red blood cell distribution width (RDW) is a value representing the heterogeneity in the size of red blood cell, and it is usually used in distinguishing types of anaemia. Recently, it was reported that it could reflect the burden of inflammation in diverse diseases and their prognosis. Hence, in this study, we investigated whether RDW may contribute to discriminating adult onset Still's disease (AOSD) from sepsis in serious febrile patients within 24 hours after hospitalization...

OBJECTIVE: The significance of cord blood neutropenia as a screening tool for early-onset sepsis (EOS) is unclear. The objectives were to define reference values for cord blood neutrophil count and to determine the sensitivity and positive likelihood ratio of cord neutropenia for the detection of EOS.

Fungi are of increasing importance in sepsis. However, culture-based diagnostic procedures are associated with relevant weaknesses. Therefore, culture- and next-generation sequencing (NGS)-based fungal findings as well as corresponding plasma levels of β-d-glucan, interferon gamma (INF-γ), tumor necrosis factor alpha (TNF-α), interleukin (IL)-2, -4, -6, -10, -17A, and mid-regional proadrenomedullin (MR-proADM) were evaluated in 50 septic patients at six consecutive time points within 28 days after sepsis onset...
