Iiv-6 Inhibits Nf-Kappab Responses In Drosophila, Cara C. West, Florentina Rus, Ying Chen, Anni Kleino, Monique Gangloff, Don B. Gammon, Neal S. Silverman Jul 2019

Iiv-6 Inhibits Nf-Kappab Responses In Drosophila, Cara C. West, Florentina Rus, Ying Chen, Anni Kleino, Monique Gangloff, Don B. Gammon, Neal S. Silverman

Neal Silverman

The host immune response and virus-encoded immune evasion proteins pose constant, mutual selective pressure on each other. Virally encoded immune evasion proteins also indicate which host pathways must be inhibited to allow for viral replication. Here, we show that IIV-6 is capable of inhibiting the two Drosophila NF-kappaB signaling pathways, Imd and Toll. Antimicrobial peptide (AMP) gene induction downstream of either pathway is suppressed when cells infected with IIV-6 are also stimulated with Toll or Imd ligands. We find that cleavage of both Imd and Relish, as well as Relish nuclear translocation, three key points in Imd signal transduction, occur …


Control Of Antiviral Innate Immune Response By Protein Geranylgeranylation, Shigao Yang, Zhaozhao Jiang, Katherine A. Fitzgerald, Donghai Wang Jul 2019

Control Of Antiviral Innate Immune Response By Protein Geranylgeranylation, Shigao Yang, Zhaozhao Jiang, Katherine A. Fitzgerald, Donghai Wang

Katherine A. Fitzgerald

The mitochondrial antiviral signaling protein (MAVS) orchestrates host antiviral innate immune response to RNA virus infection. However, how MAVS signaling is controlled to eradicate virus while preventing self-destructive inflammation remains obscure. Here, we show that protein geranylgeranylation, a posttranslational lipid modification of proteins, limits MAVS-mediated immune signaling by targeting Rho family small guanosine triphosphatase Rac1 into the mitochondria-associated endoplasmic reticulum (ER) membranes (MAMs) at the mitochondria-ER junction. Protein geranylgeranylation and subsequent palmitoylation promote Rac1 translocation into MAMs upon viral infection. MAM-localized Rac1 limits MAVS' interaction with E3 ligase Trim31 and hence inhibits MAVS ubiquitination, aggregation, and activation. Rac1 also facilitates …


Limiting Antibiotic Use In Acute Sinusitis: Partly A Matter Of Vocabulary?, Dennis J. Baumgardner Sep 2018

Limiting Antibiotic Use In Acute Sinusitis: Partly A Matter Of Vocabulary?, Dennis J. Baumgardner

Dennis J. Baumgardner, MD

In his issue introduction, the editor-in-chief of Journal of Patient-Centered Research and Reviews comments on an included article that describes the successful use of an electronic medical record best practice alert to reduce the rate of antibiotic prescription for acute sinusitis. Various methods previously tried to improve antibiotic stewardship in this illness are briefly reviewed. Borrowing on the model of acute bronchitis, it is suggested that a change in conveyed diagnostic vocabulary to “sinus cold” when describing acute sinusitis may help limit antibiotics for this predominantly viral infection.

Dengue Virus Ns2b/Ns3 Protease Inhibitors Exploiting The Prime Side, Kuan-Hung Lin, Akbar Ali, Linah Rusere, Djade I. Soumana, Nese Kurt Yilmaz, Celia A. Schiffer Jul 2017

Dengue Virus Ns2b/Ns3 Protease Inhibitors Exploiting The Prime Side, Kuan-Hung Lin, Akbar Ali, Linah Rusere, Djade I. Soumana, Nese Kurt Yilmaz, Celia A. Schiffer

Celia A. Schiffer

The mosquito-transmitted dengue virus (DENV) infects millions of people in tropical and subtropical regions. Maturation of DENV particles requires proper cleavage of the viral polyprotein, including processing of 8 of the 13 substrate cleavage sites by dengue virus NS2B/NS3 protease. With no available direct-acting antiviral targeting DENV, NS2/NS3 protease is a promising target for inhibitor design. Current design efforts focus on the nonprime side of the DENV protease active site, resulting in highly hydrophilic and nonspecific scaffolds. However, the prime side also significantly modulates DENV protease binding affinity, as revealed by engineering the binding loop of aprotinin, a small protein …

BACKGROUND:

The impact of neuraminidase inhibitors (NAIs) on influenza-related pneumonia (IRP) is not established. Our objective was to investigate the association between NAI treatment and IRP incidence and outcomes in patients hospitalised with A(H1N1)pdm09 virus infection.

METHODS:

A worldwide meta-analysis of individual participant data from 20 634 hospitalised patients with laboratory-confirmed A(H1N1)pdm09 (n = 20 021) or clinically diagnosed (n = 613) 'pandemic influenza'. The primary outcome was radiologically confirmed IRP. Odds ratios (OR) were estimated using generalised linear mixed modelling, adjusting for NAI treatment propensity, antibiotics and corticosteroids.

RESULTS:

Of 20 634 included participants, 5978 (29·0%) had IRP; conversely, …

Herpes simplex encephalitis (HSE) is the most common form of acute viral encephalitis in industrialized countries. Type I interferon (IFN) is important for control of herpes simplex virus (HSV-1) in the central nervous system (CNS). Here we show that microglia are the main source of HSV-induced type I IFN expression in CNS cells and these cytokines are induced in a cGAS-STING-dependent manner. Consistently, mice defective in cGAS or STING are highly susceptible to acute HSE. Although STING is redundant for cell-autonomous antiviral resistance in astrocytes and neurons, viral replication is strongly increased in neurons in STING-deficient mice. Interestingly, HSV-infected microglia …

R. Christopher Rustin

Background:
Zika virus (ZIKV) was declared an international public health emergency by the World Health Organization on
February 1, 2016. Due to the known and estimated range of the ZIKV mosquito vectors, southern and central US
states faced increased risk of ZIKV transmission. With the state of Georgia hosting the world’s busiest international airport, a climate that supports the ZIKV vectors, and limited surveillance (13 counties) and response capacity, the Department of Public Health (DPH) was challenged to respond and prevent ZIKV transmission. This case study describes and evaluates the state’s surveillance capacity before and after the declaration of ZIKV …

Post-Herpetic Paresis Of The Lower Extremity: An Unusual Complication Of Shingles, Leah Diane Stalnaker, Lynne J. Goebel, Md

Lynne J. Goebel

Herpes zoster, or shingles, is a disease process caused by re-activation of varicella zoster virus in the dorsal root ganglia. Most commonly, it presents with burning pain and a characteristic vesicular rash. However neurologic complications may occur, most often including neuralgia, and less commonly paresis. We present a case of post-herpetic paresis in an 86- year- old female.

BACKGROUND: Infection with dengue virus results in a wide range of clinical manifestations from dengue fever (DF), a self-limited febrile illness, to dengue hemorrhagic fever (DHF) which is characterized by plasma leakage and bleeding tendency. Although cardiac involvement has been reported in dengue, the incidence and the extent of cardiac involvement are not well defined. METHODS AND PRINCIPAL FINDINGS: We characterized the incidence and changes in cardiac function in a prospective in-patient cohort of suspected dengue cases by serial echocardiography. Plasma leakage was detected by serial chest and abdominal ultrasonography. Daily cardiac troponin-T levels were measured. One hundred and eighty …

BACKGROUND: Dengue is endemic to the rural province of Kamphaeng Phet, Northern Thailand. A decade of prospective cohort studies has provided important insights into the dengue viruses and their generated disease. However, as elsewhere, spatial dynamics of the pathogen remain poorly understood. In particular, the spatial scale of transmission and the scale of clustering are poorly characterized. This information is critical for effective deployment of spatially targeted interventions and for understanding the mechanisms that drive the dispersal of the virus.

METHODOLOGY/PRINCIPAL FINDINGS: We geocoded the home locations of 4,768 confirmed dengue cases admitted to the main hospital in Kamphaeng Phet …

BACKGROUND: The effect of prior dengue virus (DENV) exposure on subsequent heterologous infection can be beneficial or detrimental depending on many factors including timing of infection. We sought to evaluate this effect by examining a large database of DENV infections captured by both active and passive surveillance encompassing a wide clinical spectrum of disease.

METHODS: We evaluated datasets from 17 years of hospital-based passive surveillance and nine years of cohort studies, including clinical and subclinical DENV infections, to assess the outcomes of sequential heterologous infections. Chi square or Fisher's exact test was used to compare proportions of infection outcomes such …

Humans are exposed to viruses everywhere they live, play, and work. Yet people’s beliefs about viruses may be confused or inaccurate, potentially impairing their understanding of scientific information. This study used semi-structured interviews to examine people’s beliefs about viruses, vaccines, and the causes of infectious disease. We compared people at different levels of science expertise: middle school students, teachers, and professional virologists. The virologists described more entities involved in microbiological processes, how these entities behaved, and why. Quantitative and qualitative analyses revealed distinctions in the cognitive organization of several concepts, including infection and vaccination. For example, some students and teachers …

Gyongyi Szabo

Antibodies targeting receptor-mediated entry of HCV into hepatocytes confer limited therapeutic benefits. Evidence suggests that exosomes can transfer genetic materials between cells; however, their role in HCV infection remains obscure. Here, we show that exosomes isolated from sera of chronic HCV infected patients or supernatants of J6/JFH1-HCV-infected Huh7.5 cells contained HCV RNA. These exosomes could mediate viral receptor-independent transmission of HCV to hepatocytes. Negative sense HCV RNA, indicative of replication competent viral RNA, was present in exosomes of all HCV infected treatment non-responders and some treatment-naive individuals. Remarkably, HCV RNA was associated with Ago2, HSP90 and miR-122 in exosomes isolated …

Methods. A retrospective chart review of patients seen for pretravel health services in a pharmacist-run travel clinic (PTC) compared to PCPs at a University Student Health Center. Vaccine/medication recommendations were assessed for consistency with national/international guidelines. Medical/pharmacy records were queried to determine the receipt of medications/vaccinations. Results. The PTC recommended antibiotics for travelers' diarrhea were given more often when indicated (96% vs 50%, p < 0.0001), and patients seen in the PTC received their medications more …


Immunization Update, Karl M. Hess, Jeffery A. Goad Jan 2015

Immunization Update, Karl M. Hess, Jeffery A. Goad

Jeff Goad

"Immunization represents a very effective primary prevention strategy to curb the rate of vaccine preventable diseases...Pharmacists can play a leading role in vaccination by serving as an advocate, facilitator, and active immunizer. As an advocate, pharmacists provide vaccine education while motivating people to get immunized. As a facilitator, pharmacy’s can host other groups, such as the visiting nurses association, to come into the pharmacy and vaccinate. As an active immunizer, however, pharmacists serve their greatest role by giving immunizations to adolescents and adults."

Hemorrhagic Fever Viruses, Jeffery A. Goad, J Nguyen

Jeff Goad

Viral hemorrhagic fever (VHF) viruses are diverse and include arenaviruses, bunyaviruses, filoviruses, and flaviviruses. Lassa fever, South American hemorrhagic fever (HF), Rift Valley HF, Crimean-Congo HF, Ebola, Marburg, yellow fever, and dengue fever are well known examples of the hemorrhagic fever viruses. They are often difficult to diagnose and treat resulting in significant morbidity and mortality. Transmission varies from vector borne to person-to-person. The common clinical presentation includes fever, myalgia, microvascular damage, and hemorrahage as well as a history of travel to the tropics. If VHF is suspected, strict infection control procedures must be implemented to prevent the spread of …

BACKGROUND: Dengue virus is endemic in tropical and sub-tropical resource-poor countries. Dengue illness can range from a nonspecific febrile illness to a severe disease, Dengue Shock Syndrome (DSS), in which patients develop circulatory failure. Earlier diagnosis of severe dengue illnesses would have a substantial impact on the allocation of health resources in endemic countries. METHODS AND FINDINGS: We compared clinical laboratory findings collected within 72 hours of fever onset from a prospective cohort children presenting to one of two hospitals (one urban and one rural) in Thailand. Classification and regression tree analysis was used to develop diagnostic algorithms using different …

The Human/Animal Interface: Emergence And Resurgence Of Zoonotic Infectious Diseases, Michael Greger

Michael Greger, MD, FACLM

Emerging infectious diseases, most of which are considered zoonotic in origin, continue to exact a significant toll on society. The origins of major human infectious diseases are reviewed and the factors underlying disease emergence explored. Anthropogenic changes, largely in land use and agriculture, are implicated in the apparent increased frequency of emergence and reemergence of zoonoses in recent decades. Special emphasis is placed on the pathogen with likely the greatest zoonotic potential, influenzavirus A.

Homosexual and heterosexual patients with the acquired immunodeficiency syndrome were compared by risk group. Race; diagnoses; history of sexually transmitted diseases, sexual behavior, and drug use; and socioeconomic indicators differed considerably among the risk groups, suggesting different risk factors for acquisition of the syndrome. Patients in the homosexual, intravenous drug user, and Haitian risk groups differed in their serologic response to cytomegalovirus and syphilis testing, presumably due to lifestyle-related exposures. Differences in the rate of recovery of cytomegalovirus, serum levels of IgA and IgG, and antibody titers to Epstein-Barr virus were noted among patients with different diagnoses. We conclude that …

BACKGROUND: Dengue virus is endemic in tropical and sub-tropical resource-poor countries. Dengue illness can range from a nonspecific febrile illness to a severe disease, Dengue Shock Syndrome (DSS), in which patients develop circulatory failure. Earlier diagnosis of severe dengue illnesses would have a substantial impact on the allocation of health resources in endemic countries. METHODS AND FINDINGS: We compared clinical laboratory findings collected within 72 hours of fever onset from a prospective cohort children presenting to one of two hospitals (one urban and one rural) in Thailand. Classification and regression tree analysis was used to develop diagnostic algorithms using different …

Hepatitis C virus (HCV) infection is a leading cause of liver transplantation and there is an urgent need to develop therapies to reduce rates of HCV infection of transplanted livers. Approved therapeutics for HCV are poorly tolerated and are of limited efficacy in this patient population. Human monoclonal antibody HCV1 recognizes a highly-conserved linear epitope of the HCV E2 envelope glycoprotein (amino acids 412-423) and neutralizes a broad range of HCV genotypes. In a chimpanzee model, a single dose of 250 mg/kg HCV1 delivered 30 minutes prior to infusion with genotype 1a H77 HCV provided complete protection from HCV infection, …
