Journal Articles

Systemic lupus erythematosus (SLE) is characterized by multiorgan inflammation, neuropsychiatric disorders (NPSLE), and antinuclear antibodies. We previously identified a subset of anti-DNA antibodies (DNRAb) cross-reactive with the N-methyl-D-aspartate receptor, present in 30% to 40% of patients, able to enhance excitatory post-synaptic potentials and trigger neuronal apoptosis. DNRAb + mice exhibit memory impairment or altered fear response, depending on whether the antibody penetrates the hippocampus or amygdala. Here, we used 18F-fluorodeoxyglucose (FDG) microPET to plot changes in brain metabolism after regional blood-brain barrier (BBB) breach. In DNRAb + mice, metabolism declined at the site of BBB breach in the first 2 …

Journal Articles

Rapid eye movement sleep behaviour disorder has been evaluated using Parkinson's disease-related metabolic network. It is unknown whether this disorder is itself associated with a unique metabolic network. F-18-fluorodeoxyglucose positron emission tomography was performed in 21 patients (age 65.0 +/- 5.6 years) with idiopathic rapid eye movement sleep behaviour disorder and 21 age/gender-matched healthy control subjects (age 62.5 +/- 7.5 years) to identify a disease-related pattern and examine its evolution in 21 hemi-parkinsonian patients (age 62.6 +/- 5.0 years) and 16 moderate parkinsonian patients (age 56.9 +/- 12.2 years). We identified a rapid eye movement sleep behaviour disorder-related metabolic network …

Journal Articles

Inflammatory conditions characterized by excessive peripheral immune responses are associated with diverse alterations in brain function, and brain-derived neural pathways regulate peripheral inflammation. Important aspects of this bidirectional peripheral immune - brain communication, including the impact of peripheral inflammation on brain region-specific cytokine responses, and brain cholinergic signaling (which plays a role in controlling peripheral cytokine levels) remain unclear. To provide insight, we studied gene expression of cytokines, immune cell markers and brain cholinergic system components in the cortex, cerebellum, brainstem, hippocampus, hypothalamus, striatum, and thalamus in mice following an intraperitoneal lipopolysaccharide injection. Endotoxemia was accompanied by elevated serum levels …

Decreased Langerhans Cell Responses To Il-36 Gamma: Altered Innate Immunity In Patients With Recurrent Respiratory Papillomatosis, J. Devoti, L. Hatam, A. Lucs, A. Afzal, A. Abramson, B. M. Steinberg, V. Bonagura

Journal Articles

Recurrent respiratory papillomatosis (RRP) is a rare, chronic disease caused by human papillomaviruses (HPVs) types 6 and 11 that is characterized by the polarization of adaptive immune responses that support persistent HPV infection. Respiratory papillomas express elevated mRNA levels of IL-36 gamma, a proinflammatory cytokine in comparison to autologous clinically normal laryngeal tissues; however there is no evidence of inflammation in these lesions. Consistent with this, respiratory papillomas do not contain T(H)1-like CD4(+) T-cells or cytotoxic CD8(+) T-cells, but instead contain a predominance of T(H)2-like and T regulatory cells (Tregs). In addition, papillomas also are infiltrated with immature Langerhans cells …

Early Efficacy Trial Of Anakinra In Corticosteroid-Resistant Autoimmune Inner Ear Disease, A. Vambutas, M. Lesser, V. Mullooly, S. Pathak, G. Zahtz, L. M. Rosen, E. Goldofsky

Journal Articles

BACKGROUND. Autoimmune inner ear disease (AIED) is a rare disease that results in progressive sensorineural hearing loss. Patients with AIED initially respond to corticosteroids; however, many patients become unresponsive to this treatment over time, and there is no effective alternative therapy for these individuals. METHODS. We performed a phase I/II open-label, single-arm clinical trial of the IL-1 receptor antagonist anakinra in corticosteroid-resistant AIED patients. Given that the etiology of corticosteroid resistance is likely heterogeneous, we used a Simon 2-stage design to distinguish between an unacceptable (= 30%) response rate to anakinra therapy. Subjects received 100 mg anakinra by subcutaneous injection …

BACKGROUND & AIMS: High mobility group box 1 (HMGB1) is an abundant protein that regulates chromosome architecture and also functions as a damage-associated molecular pattern molecule. Little is known about its intracellular roles in response to tissue injury or during subsequent local and systemic inflammatory responses. We investigated the function of Hmgb1 in mice after induction of acute pancreatitis. METHODS: We utilized a Cre/LoxP system to create mice with pancreas-specific disruption in Hmbg1 (Pdx1-Cre; HMGB1(flox/flox) mice). Acute pancreatitis was induced in these mice (HMGB1(flox/flox) mice served as controls) after injection of l-arginine or cerulein. Pancreatic tissues and acinar cells were …

Hmgb1-Dna Complex-Induced Autophagy Limits Aim2 Inflammasome Activation Through Rage, L. Y. Liu, M. H. Yang, R. Kang, Y. P. Dai, X. J. Sun, X. L. Li, J. H. Li, H. C. Wang, L. Z. Cao, D. L. Tang, +3 Additional Authors

Journal Articles

High mobility group box 1 (HMGB1) is a prototype damage-associated molecular pattern (DAMP) that can induce inflammatory and immune responses alone as well as in combination with other molecules such as DNA. However, the intricate molecular mechanisms underlying HMGB1-DNA complex-mediated innate immune response remains largely elusive. In this study, we demonstrated that HMGB1-DNA complex initially induced absent in melanoma 2 (AIM2)-dependent inflammasome activation, and promoted rapid release of inflammasome-dependent early proinflammatory cytokines such as interleukin 10 (IL-1 beta). Subsequently, HMGB1 - DNA complex stimulated an ATG5-dependent cellular degradation process, autophagy, which was paralleled by a cessation of AIM2 inflammasome activation …

Molecular Mechanism And Therapeutic Modulation Of High Mobility Group Box 1 Release And Action: An Updated Review, B. Lu, C. Wang, M. Wang, W. Li, F. P. Chen, K. J. Tracey, H. C. Wang

Journal Articles

High mobility group box 1 (HMGB1) is an evolutionarily conserved protein, and is constitutively expressed in virtually all types of cells. Infection and injury converge on common inflammatory responses that are mediated by HMGB1 secreted from immunologically activated immune cells or passively released from pathologically damaged cells. Herein we review the emerging molecular mechanisms underlying the regulation of pathogen-associated molecular patterns (PAMPs)-induced HMGB1 secretion, and summarize many HMGB1-targeting therapeutic strategies for the treatment of infection- and injury-elicited inflammatory diseases. It may well be possible to develop strategies that specifically attenuate damage-associated molecular patterns (DAMPs)-mediated inflammatory responses without compromising the PAMPs-mediated …

Mirror Image Artifact Mimicking Heterotopic Pregnancy On Transvaginal Ultrasound: Case Series, R. Malhotra, R. M. Bramante, M. Radomski, M. Nelson Jan 2014

Mirror Image Artifact Mimicking Heterotopic Pregnancy On Transvaginal Ultrasound: Case Series, R. Malhotra, R. M. Bramante, M. Radomski, M. Nelson

Journal Articles

Vaginal bleeding in early pregnancy is a common emergency department complaint. Point-of-care ultrasound is a useful tool to evaluate for intrauterine ectopic pregnancy. Emergency physicians performing these studies need to be cognizant of artifacts produced by ultrasound technology, as they can lead to misdiagnosis. We present two cases where mirror-image artifacts initially led to a concern for heterotopic pregnancies but were excluded on further imaging.

Journal Articles

BACKGROUND: Some reports indicate financial concerns as a factor affecting ED patients leaving the acute care setting against medical advice (AMA). In India, no person is supposed to be denied urgent care because of inability to pay. Since a large proportion of the Indian health care system is financed by out-of-pocket expenses, we investigate the role of financial constraints for ED patients at a private hospital in India in leaving AMA. METHODS: A prospective ED-based cross-sectional survey of patients leaving AMA was conducted at a private hospital in India from 1 October 2010 to 31 December 2010. Descriptive statistics and …

Case Report: Transient Small Bowel Intussusception Presenting As Right Lower Quadrant Pain In A 6-Year-Old Male, M. J. Nelson, T. Paterson, C. Raio

Journal Articles

In children presenting to the emergency room with right lower quadrant pain, ultrasound is the preferred initial modality. In our patient, a 6-year-old male with a sudden onset of severe right lower quadrant pain, the differential is broad, including appendicitis and intussusception. In order to narrow our differential and secure the diagnosis, our first modality was ultrasonography. With the increased use of point-of-care ultrasound in the emergency department, the diagnosis of appendicitis and ileo-colic intussusception has been made more frequently. In addition, other entities such as transient small bowel intussusception may be identified. As in our case, obstruction secondary to …

Gene-Based Therapies In Parkinson's Disease, P. J. Allen, A. Feigin Jan 2014

Gene-Based Therapies In Parkinson's Disease, P. J. Allen, A. Feigin

Journal Articles

Parkinson's disease (PD) is a progressive neurological disorder characterized primarily by the degeneration of nigrostriatal dopaminergic neurons and diminution of the neurotransmitter dopamine. Though dopamine replacement therapies such as levodopa can improve the symptoms of PD, the benefits may be overshadowed by side effects and the onset of symptoms not responsive to dopaminergic treatments (e.g., autonomic symptoms, gait and balance problems, and cognitive impairment). Furthermore, no therapies have proven to slow the neurodegenerative process. Novel approaches to address these difficult problems, and others, are being sought. Over the last decade, several innovative gene therapies for PD have entered human clinical …

Near-Infrared Spectroscopy And Plasma Homovanillic Acid Levels In Bipolar Disorder: A Case Report, I. Miura, S. Kono, S. Oshima, K. Kanno-Nozaki, H. Mashiko, S. I. Niwa, H. Yabe

Journal Articles

Misdiagnosis of bipolar disorder is a serious, but not unusual problem for patients. Nevertheless, there are few biomarkers for distinguishing unipolar and bipolar disorder. Near-infrared spectroscopy (NIRS) is a noninvasive and useful method for the measurement of hemoglobin concentration changes in the cortical surface area, which enables the assessment of brain function. We measured NIRS and plasma monoamine metabolite levels in a patient with bipolar disorder. A 22-year-old man was admitted due to major depression. At admission, NIRS findings showed oxygenated hemoglobin reincrease in the posttask period, which is characteristic of schizophrenia. After treatment with paroxetine, he became manic with …

Journal Articles

Objective It is important to predict a response to an antidepressant in early time after starting the antidepressant. We previously reported that serum brain-derived neurotrophic factor (BDNF) levels in responders to treatment with antidepressants were increased, whereas, those in nonresponders were not. Therefore, we hypothesized that the changes in serum levels of BDNF from baseline (TO) to 4 weeks (T4) after treatment with selective serotonin reuptake inhibitors (SSRIs) predict the response to the treatment at 8 weeks (T8) in depressed patients. To confirm the hypothesis, we measured serum BDNF at TO, T4, and T8 during the treatment with SSRIs (paroxetine, …

Journal Articles

Copy number variants (CNVs) are risk factors in neurodevelopmental disorders, including autism, epilepsy, intellectual disability (ID) and schizophrenia. Childhood onset schizophrenia (COS), defined as onset before the age of 13 years, is a rare and severe form of the disorder, with more striking array of prepsychotic developmental disorders and abnormalities in brain development. Because of the well-known phenotypic variability associated with pathogenic CNVs, we conducted whole genome genotyping to detect CNVs and then focused on a group of 46 rare CNVs that had well-documented risk for adult onset schizophrenia (AOS), autism, epilepsy and/or ID. We evaluated 126 COS probands, 69 …

Until relatively recently, long-acting injectable (LAI) formulations were only available for first-generation antipsychotics and their utilization decreased as use of oral second-generation antipsychotics (SGA) increased. Although registry-based naturalistic studies show LAIs reduce rehospitalization more than oral medications in clinical practice, this is not seen in recent randomized clinical trials. PROACTIVE (Preventing Relapse Oral Antipsychotics Compared to Injectables Evaluating Efficacy) relapse prevention study incorporated efficacy and effectiveness features. At 8 US academic centers, 305 patients with schizophrenia or schizoaffective disorder were randomly assigned to LAI risperidone (LAI-R) or physician's choice oral SGAs. Patients were evaluated during the 30-month study by masked, …

Dopaminergic Influences On Emotional Decision Making In Euthymic Bipolar Patients, K. E. Burdick, R. J. Braga, C. B. Gopin, A. K. Malhotra

Journal Articles

We recently reported that the D2/D3 agonist pramipexole may have pro-cognitive effects in euthymic patients with bipolar disorder (BPD); however, the emergence of impulse-control disorders has been documented in Parkinson's disease (PD) after pramipexole treatment. Performance on reward-based tasks is altered in healthy subjects after a single dose of pramipexole, but its potential to induce abnormalities in BPD patients is unknown. We assessed reward-dependent decision making in euthymic BPD patients pre- and post 8 weeks of treatment with pramipexole or placebo by using the Iowa Gambling Task (IGT).

Background. Recent data suggest trait-like neurocognitive impairments in bipolar disorder (BPD), with deficits about 1 S.D. below average, less severe than deficits noted in schizophrenia. The frequency of significant impairment in BPD is approximately 60%, with 40% of patients characterized as cognitively spared. This contrasts with a more homogeneous presentation in schizophrenia. It is not understood why some BPD patients develop deficits while others do not. Method. A total of 136 patients with BPD completed the MATRICS Consensus Cognitive Battery and data were entered into hierarchical cluster analyses to: (1) determine the optimal number of clusters (subgroups) that fit the …

Multisite longitudinal neuroimaging designs are used to identify differential brain structural change associated with onset or progression of disease. The reliability of neuroanatomical measurements over time and across sites is a crucial aspect of power in such studies. Prior work has found that while within-site reliabilities of neuroanatomical measurements are excellent, between-site reliability is generally more modest. Factors that may increase between-site reliability include standardization of scanner platform and sequence parameters and correction for between-scanner variations in gradient nonlinearities. Factors that may improve both between- and within-site reliability include use of registration algorithms that account for individual differences in cortical …
