Background: Chronic granulomatous disease (CGD) is a rare genetic disorder causing recurrent infections. Over one quarter of patients develop hepatic abscesses and liver dysfunction. Recent reports suggest disease-modifying treatment with corticosteroids is effective for these abscesses. Comparison of corticosteroid therapy to traditional invasive treatments has not been performed. Methods: Records of 268 patients with CGD treated at the National Institutes of Health (NIH) from 1980 to 2014 were reviewed...

BACKGROUND: Chronic disseminated candidiasis (CDC) is a severe invasive fungal infection principally observed during neutrophil recovery in patients with acute leukemia treated with intensive chemotherapy. Its pathophysiology remains unclear. We describe the management of six children with symptomatic CDC who did not respond to antifungal therapy. METHODS: The databases of the hematology-oncology departments of two tertiary pediatric medical centers were searched for all patients diagnosed with CDC from 2003 to 2015 who responded to corticosteroids after failing antifungal therapy...

BACKGROUND: The tumor necrosis factor superfamily member LIGHT (the official gene symbol approved by NCBI Gene Database), an inflammatory factor secreted by T cells after allergen exposure, recently discovered to play crucial roles in asthmatic airway remodeling. However, it is unclear whether LIGHT could be controlled by inhaled corticosteroids, a key component of asthma management. This study was to investigate the effects and potential mechanisms of inhaled budesonide on the expressions of LIGHT and its receptors (LTβR and HVEM) of lung tissues in ovalbumin-sensitized mice...

In the United States, perinatal brain injury (PBI) is a major cause of infant mortality and childhood disability. For a large proportion of infants with PBI, central nervous system (CNS) injury begins in utero with inflammation (chorioamnionitis/CHORIO) and/or hypoxia-ischemia. While studies show CHORIO contributes to preterm CNS injury and is also a common independent risk factor for brain injury in term infants, the molecular mechanisms mediating inflammation in the placental-fetal-brain axis that result in PBI remain a gap in knowledge...

Myeloid differentiation factor 88 (MyD88) and Toll or interleukin-1 receptor-domain-containing adaptor-inducing interferon-β (IFN-β) (TRIF) are two pivotal downstream adaptors of Toll-like receptors. Activation of MyD88 or TRIF signaling in cardiac immune pathology of severe inflammation negatively influences heart function. In the present study, severe septic cardiac injury was induced in C57BL/6 mice by cecum ligation and puncture (CLP). A total of 64 mice were divided randomly into the following four groups (n=16/group; 8 for observation of survival rate, 8 for heart sample analysis): Sham, CLP, anti-MyD88-CLP and anti-TRIF-CLP...

The importance of nontargeted (systemic) effects of ionizing radiation is attracting increasing attention. Exploiting synchrotron radiation generated by the Imaging and Medical Beamline at the Australian Synchrotron, we studied radiation-induced nontargeted effects in C57BL/6 mice. Mice were locally irradiated with a synchrotron X-ray broad beam and a multiplanar microbeam radiotherapy beam. To assess the influence of the beam configurations and variations in peak dose and irradiated area in the response of normal tissues outside the irradiated field at 1 and 4 days after irradiation, we monitored oxidatively induced clustered DNA lesions (OCDL), DNA double-strand breaks (DSB), apoptosis, and the local and systemic immune responses...

Dallan McMahon, Kullervo Hynynen
Rationale: Focused ultrasound (FUS), in conjunction with circulating microbubbles (MBs), can be used to transiently increase the permeability of the blood-brain barrier (BBB) in a targeted manner, allowing therapeutic agents to enter the brain from systemic circulation. While promising preclinical work has paved the way for the initiation of 3 human trials, there remains concern regarding neuroinflammation following treatment. The aim of this study was to assess the magnitude of this response following sonication and explore the influence of MB dose...

The medical records of 44 pediatric patients who underwent allogeneic transplantation from 2011 to 2015 were retrospectively reviewed. Magnetic resonance imaging was used to measure iron concentrations in the liver, spleen, pancreas and bone. These patients were divided into two groups, 18 with non-elevated (< 100 μmol/g; Group 1) liver iron concentration before transplantation and 26 with elevated (> 100 μmol/g; Group 2) concentration . We compared transplant-related outcomes in the two groups. Iron overload was a negative prognostic risk factor for sinusoidal obstruction syndrome (OR = 17), osteoporosis (OR = 6...

Leishmania major is the causative agent of the neglected tropical disease, cutaneous leishmaniasis. In the mouse, protective immunity to Leishmania is associated with inflammatory responses. Here, we assess the dynamics of the inflammatory responses at the lesion site during experimental long-term, low-dose intradermal infection of the ear, employing noninvasive imaging and genetically modified L. major Significant infiltrates of neutrophils and monocytes occurred at 1-4 d and 2-4 wk, whereas dermal macrophage and dendritic cell (DC) numbers were only slightly elevated in the first days...

Myocardial infarction (MI) is accompanied by cardiac fibrosis, which contributes to cardiac dysfunction. Mineralocorticoid receptor (MR) antagonists have beneficial effects in patients with left ventricular (LV) dysfunction after MI. We herein investigated the role of the MR target NGAL (neutrophil gelatinase-associated lipocalin) in post-MI cardiac damages. Both higher baseline NGAL and a greater increase in serum NGAL levels during follow-up were significantly associated with lower 6-month LV ejection fraction recovery in a cohort of 119 post-MI patients, as assessed by cardiac magnetic resonance imaging...

Background Chronic granulomatous disease (CGD) is a hereditary immunodeficiency caused by mutations in genes encoding nicotinamide adenine dinucleotide phosphate oxidase enzyme complex, which lead to the inability to kill intracellular pathogens. Patients with CGD are susceptible to recurrent bacterial and fungal infections in their early lives. Although the recent survival rate has been significantly improved, early diagnosis is critical to prevent multiple organ impairment. In 1950s, CGD was first described as a disease with recurrent infections and visceral infiltration of granulomas and pigmented histiocytes...

Neutrophils are capable of releasing their DNA in response to infectious agents to form neutrophil extracellular traps (NETs) to destroy pathogens. Even though pyometra in queens and bitches is a common disease, its pathogenesis is not fully understood. The aim of this study was to assess the presence of NETs in the endometrium of queens and bitches suffering from pyometra. Pyometra and normal uteri were obtained after ovariohysterectomy from adult queens and bitches in diestrus. Uterine contents were evaluated for bacterial isolation and identification and for NETs presence...

BACKGROUND: Despite recent advances, infection remains the most common etiology of arthroplasty failure. Recent work suggests that 25-hydroxyvitamin D (25D) deficiency correlates with the frequency of periprosthetic joint infection (PJI). We endeavored to examine whether 25D3 deficiency leads to increased bacterial burden in vivo in an established mouse model of PJI and, if so, whether this effect can be reversed by preoperative 25D3 supplementation. METHODS: Mice (lys-EGFP) possessing fluorescent neutrophils were fed a vitamin D3-sufficient (n = 20) or deficient (n = 40) diet for 6 weeks...

In vivo detection and quantification of inflammation is a major goal in molecular imaging. Furthermore, cell-specific detection of inflammation would be a tremendous advantage in the characterization of many diseases. Here, we show how this goal can be achieved through the synergistic combination of nanotechnology and nuclear imaging. One of the most remarkable features of this hybrid approach is the possibility to tailor the pharmacokinetics of the nanomaterial-incorporated biomolecule and radionuclide. A good example of this approach is the covalent binding of a large amount of a neutrophil-specific, hydrophobic peptide on the surface of (68)Ga core-doped nanoparticles...

Candida spp. adhere to medical devices, such as catheters, forming drug-tolerant biofilms that resist killing by the immune system. Little is known about how C. glabrata, an emerging pathogen, resists attack by phagocytes. Here we show that upon encounter with planktonic (non-biofilm) C. glabrata, human neutrophils initially phagocytose the yeast and subsequently release neutrophil extracellular traps (NETs), complexes of DNA, histones, and proteins capable of inhibiting fungal growth and dissemination. When exposed to C...
