The Human Cytomegalovirus (HCMV) US12 gene family encodes a group of predicted seven-transmembrane proteins whose functions have yet to be established. While inactivation of individual US12 members in laboratory strains of HCMV does not affect viral replication in fibroblasts, disruption of the US16 gene in the low-passage TR strain prevents viral growth in endothelial and epithelial cells. In these cells, the US16-null viruses fail to express IE, E, and L viral proteins due to a defect which occurs prior to IE gene expression...

Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for clearing secretions in HE and AECOPD patients.The present study is a prospective cohort study of AECOPD and HE patients enrolled between October 2013 and August 2015 in a critical care unit of a major university teaching hospital in China...

BACKGROUND: The introduction of newborn hearing screening has led to earlier identification of children with congenital sensorineural hearing loss (SNHL). Aetiological clarification offers several benefits. There is currently a lack of agreement on which examinations should be recommended. OBJECTIVE: Descriptive review of the literature reporting investigations performed to establish the aetiology of congenital SNHL and comparison of the management policy in Swiss referral centres...

Inflammation is known to preclude tolerance after transplantation. We have previously shown that systemic inflammation in xenograft recipients (SIXR) precedes activation of coagulation in the absence of T cell responses. Accordingly, SIXR may amplify innate and adaptive immune responses against xenografts after pig-to-primate xenotransplantation, even with efficient immunosuppressive therapy. We evaluated the impact of anti-inflammatory agents on pro-inflammatory cytokines and chemokines in pig artery patch and heart xenograft recipients...

A single subcutaneous (SC) injection of plerixafor results in rapid mobilization of hematopoietic progenitors but fails to mobilize 33% of normal allogeneic sibling donors in one apheresis. We hypothesized that changing the route of administration of plerixafor from SC to intravenous (IV) may overcome the low stem cell yields and allow collection in one day. A phase I trial followed by a phase II efficacy trial was conducted in allogeneic sibling donors. The optimal dose of IV plerixafor was determined to be 0...

Sporadic inclusion body myositis, a variant of inflammatory myopathy, has features distinct from polymyositis/dermatomyositis. The disease affects men more than women, most commonly after age 50. Clinical features include weakness of the quadriceps, finger flexors, ankle dorsiflexors, and dysphagia. The distribution of weakness is similar to Becker muscular dystrophy, where we previously reported improvement following intramuscular injection of an isoform of follistatin (FS344) by AAV1. For this clinical trial, rAAV1...

Although tacrolimus (Tac) has immunosuppressive properties and exhibits promising efficacy against graft-versus-host disease (GVHD), little is known about Tac in the prophylaxis of GVHD after HLA-haploidentical hematopoietic stem cell transplantation (haplo-HSCT). In a multicenter randomized controlled trial, 174 patients received haplo-HSCT with GVHD prophylaxis involving short-term Tac (from -8days to +30days) or cyclosporine (CsA). The 100day cumulative incidences of acute GVHD (aGVHD) and grade III-IV aGVHD with the short-term Tac regimen and CsA regimen were 29...

BACKGROUND: In healthy individuals, Cytomegalovirus (CMV) infection is efficiently controlled by CMV-specific cell-mediated immunity (CMI). Functional impairment of CMI in immunocompromized individuals however can lead to uncontrolled CMV replication and severe clinical complications. Close monitoring of CMV-specific CMI is therefore clinically relevant and might allow a reliable prognosis of CMV disease as well as assist personalized therapeutic decisions. METHODS: Objective of this work was the optimization and technical validation of an IFN-γ ELISpot assay for a standardized, sensitive and reliable quantification of CMV-reactive effector cells...

BACKGROUND: Epstein-Barr virus (EBV) and human cytomegalovirus (CMV) infections are environmental risk factors affecting the outcome of cancer due to an impairment in the cell-mediated immunity. Therefore, this study aimed to detect the frequency of EBV and CMV DNA and their association with clinical characteristics and outcome of pediatric leukemic patients. METHODS: Samples of 50 immunocompromised pediatric leukemic patients and 30 apparently healthy children were subjected to the amplification of EBV DNA by one version of PCR targeting the Bam H1 W region of the genomic region of EBV, and the amplification of CMV DNA by targeting the CMV UL97 genomic region by a second round PCR...

Infection with Listeria monocytogenes during pregnancy is associated with miscarriage, preterm birth, and neonatal complications, including sepsis and meningitis. While the risk of these conditions is thought to be greatest during the third trimester of pregnancy, the determinants of fetoplacental susceptibility to infection, the contribution of gestational age, and the in vivo progression of disease at the maternal-fetal interface are poorly understood. We developed a nonhuman primate model of listeriosis to better understand antecedents of adverse pregnancy outcomes in early pregnancy...

BACKGROUND: Tyrosinemia is an inherited metabolic disorder characterized by elevated levels of tyrosine and its metabolites in plasma. Without treatment, the disease will progress to hepatic and renal failure, so that without liver transplantation will cause death in less than 10 years of age. So, early diagnosis and treatment can be life saving and crucial. It means that with early treatment starting in the neonatal period, the patient can have normal life with very few restrictions in diets containing tyrosine and phenylalanine...

It is well known that CD8(+) tumor-infiltrating lymphocytes (TILs) are correlated with positive prognoses in cancer patients and are used to determine the efficacy of immune therapies. Although it is generally assumed that CD8(+) TILs will be tumor-associated Ag (TAA) specific, it is unknown whether CD8(+) T cells with specificity for common pathogens also infiltrate tumors. If so, the presence of these T cells could alter the interpretation of prognostic and diagnostic TIL assays. We compared TAA-specific and virus-specific CD8(+) T cells in the same tumors using murine CMV, a herpesvirus that causes a persistent/latent infection, and vaccinia virus, a poxvirus that is cleared by the host...

BACKGROUND: Diarrhea, a common complication after solid organ transplant (SOT), is associated with allograft failure and death. No evidence-based guidelines exist for the evaluation of diarrhea in SOT recipients. We performed a cost analysis to derive a testing algorithm for the diagnosis of community-onset diarrhea that minimizes costs without compromising diagnostic yields. DESIGN: A cost analysis was performed on a retrospective cohort of 422 SOT admissions for community-onset diarrhea over an 18-month period...

Successful preemptive therapy for cytomegalovirus (CMV) infection after hematopoietic stem cell transplantation (HSCT) depends on the availability of a rapid and sensitive assay to guide early treatment. Currently, the antigenemia assay and the quantitative real-time PCR (qPCR) assay are widely used for this purpose, but they have distinctive concerns. This study aimed to develop and evaluate a novel CMV diagnostic test based on transcription-reverse transcription concerted reaction (TRC), an RNA-detecting technology...

AIM: The aim of this study was the characterization of a new subtype of high-grade cervical squamous intraepithelial lesion (HSIL) with enlarged cells containing bizarre nuclei: so-called bizarre cell dysplasia (BCD). METHODS: A total of 29 cervical cone biopsy samples of this type of dysplasia were studied. Multi-target polymerase chain reaction and in situ hybridization human papillomavirus (HPV) detection was performed in all cases. BCD was defined as a subtype of HSIL characterized by the presence of large dysplastic cells with abnormal, large pleomorphic nuclei or multinucleation causing nucleomegaly...

Although severe flare of ulcerative colitis (UC) is uncommon, it significantly increases the risk of preterm delivery, low birth weight and other adverse fetal outcomes. It is critical to optimize aggressive medical treatment with both mother and fetal health. Here, we present a case of a 30-year-old woman with a severe flare of UC at the 16th gestational week. The diagnosis of extensive UC was established 8 years ago. From the time she was diagnosed, she had 5 moderate flares successfully treated with oral and topical mesalamine...

T cell responses to viruses are initiated and maintained in tissue sites; however, knowledge of human antiviral T cells is largely derived from blood. Cytomegalovirus (CMV) persists in most humans, requires T cell immunity to control, yet tissue immune responses remain undefined. Here, we investigated human CMV-specific T cells, virus persistence and CMV-associated T cell homeostasis in blood, lymphoid, mucosal and secretory tissues of 44 CMV seropositive and 28 seronegative donors. CMV-specific T cells were maintained in distinct distribution patterns, highest in blood, bone marrow (BM), or lymph nodes (LN), with the frequency and function in blood distinct from tissues...
