Crimean-Congo hemorrhagic fever infection (CCHF) is a viral zoonosis. The pathogenesis of this disease has not been established so far, however cytokines account for its progression and outcome. The aim of the present study is to investigate the association between chemokine receptor 5 (CCR5) gene Δ32 mutation and pathogenity, severity, and mortality of CCHF. This case-control study included 133 CCHF patients diagnosed by detection of CCHV RNA positivity and 97 healthy control subjects. CCR5 gene Δ32 mutation analyzed by polymerase chain reaction (PCR) method...

The recent Middle East respiratory syndrome coronavirus (MERS-CoV), Ebola and Zika virus outbreaks exemplify the continued threat of (re-)emerging viruses to human health, and our inability to rapidly develop effective therapeutic countermeasures. Many viruses, including MERS-CoV and the Crimean-Congo hemorrhagic fever virus (CCHFV) encode deubiquitinating (DUB) enzymes that are critical for viral replication and pathogenicity. They bind and remove ubiquitin (Ub) and interferon stimulated gene 15 (ISG15) from cellular proteins to suppress host antiviral innate immune responses...

Reston virus (family Filoviridae) is unique among the viruses of the Ebolavirus genus in that it is considered non-pathogenic in humans, in contrast to the other members which are highly virulent. The virus has however, been associated with several outbreaks of highly lethal hemorrhagic fever in non-human primates (NHPs), specifically cynomolgus monkeys (Macaca fascicularis) originating in the Philippines. In addition, Reston virus has been isolated from domestic pigs in the Philippines. To better understand virus spillover events and potential adaption to new hosts, the whole genome sequences of representative Reston virus isolates were obtained using a next generation sequencing (NGS) approach and comparative genomic analysis and virus fitness analyses were performed...

BACKGROUND: Viruses belonging to the Flaviviridae and Bunyaviridae families show considerable genetic diversity. However, this diversity is not necessarily taken into account when developing diagnostic assays, which are often based on the pairwise alignment of a limited number of sequences. Our objective was to develop and evaluate a bioinformatics workflow addressing two recurrent issues of molecular assay design: (i) the high intraspecies genetic diversity in viruses and (ii) the potential for cross-reactivity with close relatives...

THE COAGULATION SYSTEM: Abnormalities in natural physiologic anticoagulants are observed in dengue infection. Laboratory values such as protein C (PC), protein S (PS), and antithrombin (AT) indicate this problem on the coagulation system in dengue. Recently, an interrelationship between dengue and the levels of natural anticoagulants has been observed. OBJECTIVE: The study conducted to find out the effect of dengue on the natural anticoagulant proteins. METHODS: A case-control study was conducted in Port Sudan Teaching Hospital from February 2013 to June 2014 for 334 cases of dengue caused by dengue virus, 217 (65%) males and 117 (35%) were females along with 101 cases of control 64 (63...

Hemorrhagic fever with renal syndrome (HFRS) is caused by Hantaan virus (HTNV) and Seoul virus infection in Asia. The clinical manifestation of HFRS is characterized by the rapid loss of renal function (acute kidney injury) and thrombocytopenia. The specific immune mechanisms that cause thrombocytopenia in HFRS are not well described. The growth arrest-specific 6 (Gas6) protein and TAM (Tyro3, Axl and Mer) receptors have been recently shown to play prominent roles in immune regulation, and high plasma levels of Gas6 may predict the severity of diseases...

Dengue virus (DENV) co-circulates as four serotypes (DENV1-4). Primary infection only leads to self-limited dengue fever. But secondary infection with another serotype carries a higher risk of increased disease severity, causing life-threatening dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). Serotype cross-reactive antibodies facilitate DENV infection in Fc-receptor-bearing cells by promoting virus entry via Fcγ receptors (FcγR), a process known as antibody dependent enhancement (ADE). Most studies suggested that enhancing antibodies were mainly specific to the structural premembrane protein (prM) of DENV...

Spontaneous subarachnoid hemorrhage (SAH) as the presenting feature of infective endocarditis (IE) is rare. It has classically been described in association with the rupture of intracranial mycotic aneurysms (ICMA). Here we describe a very rare case of non-aneurysmal spontaneous SAH in a patient with IE. The patient originally presented with a headache and low-grade fever. Neuroimaging including computed tomography (CT) and magnetic resonance imaging (MRI) of the head revealed SAH. She was eventually diagnosed with streptococcus gallolyticus (formerly streptococcus bovis) IE...

Diverticular disease is frequent amongst the elderly and immunosuppressed patients. It mainly presents as sigmoid diverticulitis, but severe complications, like bleedings, infections and colon perforation may occur, frequently due to immunosuppressive therapy. Moreover, antibiotherapy and hemostatics may not efficiently control evolution in such cases. Early diagnose and adequate treatment of colonic diverticulosis complicated with lower gastrointestinal bleeding and diverticulitis in immunocompromised patients...

In January 2016, a migrant worker who returned home to India after becoming ill in Oman was confirmed to have Crimean-Congo hemorrhagic fever (CCHF). Physicians should include CCHF in the differential diagnosis for patients with hemorrhagic signs and a history of recent travel to any area where CCHF is endemic or prevalent.

We report a case of primary central nervous system vasculitis (PCNSV) mimicking a cortical brain tumor. A 25-year-old woman presented with a 2-week history of headache and transient right hemiparesis. Brain magnetic resonance imaging (MRI) revealed a cortical-involving lesion on the left frontal lobe. The 6-cm sized lesion showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. The lesion had continual linear enhancement on the subcortical white matter and leptomeninges...

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne nairovirus of the Bunyaviridae family, causing severe illness with high mortality rates in humans. Here we demonstrate that CCHFV nucleocapsid protein (CCHFV-NP) augments mRNA translation. CCHFV-NP binds to the viral mRNA 5' UTR with high affinity. It facilitates the translation of reporter mRNA both in vivo and in vitro with the assistance of viral mRNA 5' UTR. CCHFV-NP equally favors the translation of both capped and uncapped mRNAs, demonstrating the independence of this translation strategy on the 5' cap...

In contrast to animals, Crimean-Congo hemorrhagic fever (CCHF) causes a severe disease in humans with a high mortality rate. The etiological agent, CCHF virus (CCHFV), can be transmitted by argasid and ixodid ticks, but arachnids of the genus Hyalomma, followed by Rhipicephalus and Dermacentor serve as the major vectors of this virus. The goal of the study was to assess the epidemiological situation of CCHFV infection in cattle in south-east Poland, and survey for potential tick vector species. A total of 592 bovine blood samples from animals located in the southernmost region in Poland were tested by IgG sandwich enzyme-linked immunosorbent assay...

The Old World (OW) arenavirus Lassa (LASV ) is estimated to infect several hundred thousand people yearly in West Africa, resulting in high numbers of Lassa fever (LF), a viral hemorrhagic fever (HF) disease associated with high morbidity and mortality. To date, no licensed vaccines are available to LASV infections, and anti-LASV drug therapy is limited to an off-label use of ribavirin (Rib) that is only partially effective. The development of reverse genetics has provided investigators with a novel and powerful approach for the investigation of the molecular, cell biology, and pathogenesis of LASV...
