Here we reported two patients who presented with panuveitis and were transferred from ophthalmologists to rheumatologists, for both the patients had oral and genital ulcers. They were misdiagnosed with Behcet's disease at first glance. Two young males presented with acute uveitis with history of recurrent oral and genital ulcers. They initially presented with symptoms and signs resembling Behcet's disease and were treated with systemic steroids with suboptimal responses. Routine laboratory test revealed syphilis and human immunodeficiency virus (HIV) infection...

BACKGROUND: Cytomegalovirus (CMV) has a role in chronic rejection and graft loss in kidney transplant (KTx) and lung transplant (LTx) recipients. In addition, donor CMV seropositivity is an independent risk factor for renal graft loss. The anti-CMV response might modulate this risk. Expression of programmed cell death 1 (PD-1), a receptor involved in viral-specific T-cell exhaustion, is influenced by a single nucleotide polymorphism called PD-1.3 (wild-type allele G, variant allele A)...

Breast milk is considered ideal food for premature infants, but it can also be the main source of cytomegalovirus (CMV) infection in premature infants. CMV infection may cause serious clinical symptoms, such as sepsis-like syndrome, thrombocytopenia, neutropenia, jaundice, hepatitis, and pneumonitis. This article reviews the research advances in symptoms, treatment strategies, prognosis and the prevention of breast milk-acquired CMV infection in premature infants.

Cycloadditions of N-substituted C-(diethoxyphosphoryl)nitrones to N-allylated quinazoline-2,4-diones functionalized at N3 with substituted benzoyl or benzyl groups proceeded with moderate to good diastereoselectivities (d.e. 28-68%). The synthesized isoxazolidine phosphonates were assessed for the antiviral activity against a broad range of DNA and RNA viruses. Compounds trans-13c, cis-13c/trans-13c (86:14), cis-15b/trans-15b (87:13) and trans-15d/cis-15d (95:5) exhibited the highest activity toward both TK(+) and TK(-) VZV strains (mean EC50 values in the range of 3...

Congenital cytomegalovirus (CMV) infection causes severe disabilities and developmental delays. Women's awareness of CMV is low. Only about half of healthcare providers report counseling women about behaviors to reduce CMV risk and public health education is limited. Routine CMV counseling is not recommend. Providers may lack time to counsel women; other conditions may take priority for counseling; there may be a perception that women are reluctant to follow advice. This cross-sectional descriptive study examined women's attitudes toward CMV prevention behaviors...

OBJECTIVES: Gastrointestinal infections by cytomegalovirus (CMV) and adenovirus may complicate hematopoietic stem cell transplantation (HSCT). Although CMV and adenovirus produce recognizable cytopathic changes, these changes may be subtle or focal. The value of viral immunohistochemistry in detecting infection in HSCT recipients when cytopathic changes are not identified has not been demonstrated. METHODS: H&E-stained sections from gastrointestinal biopsy specimens were reviewed by three pathologists...

BACKGROUND: Gancyclovir-resistant (GanR) cytomegalovirus (CMV) remains an issue, especially in solid organ transplant (SOT) recipients. Some mutations in UL54 and UL97 confer this resistance. Long-lasting high-dose drug exposure, high viral load, together with lack of sufficient compliance with treatment may account for these mutations. The aim of this study was to detect UL97 and UL54 putative mutations conferring ganciclovir-resistance in renal organ transplant recipients with high CMV load...

Tumor stromal cells play a critical role in the progression of diffuse-type gastric cancer (DGC). The aim of this study was to clarify where tumor stromal cells originate from and which factor(s) recruits them into the tumor stroma. Immunodeficient mice with bone marrow transplantation from the cytomegalovirus enhancer/chicken β-actin promoter-enhanced green fluorescent protein mice were used for the in vivo experiments. An in vitro study analyzed the chemotaxis-stimulating factor from DGC cells using bone marrow-derived mesenchymal cells (BM-MCs)...

Endometritis is nowadays rare in developed countries and typically shows a subclinical or mild course; therefore, there are probably more cases of endometritis than diagnosed but they lack clinical relevance. In the fertile period of life it can be the reason for vaginal bleeding and infertility. The most common causes for non-specific endometritis are residual placental tissue after abortion or childbirth, intrauterine interventions, lesions within the uterine cavity, such as endometrial polyps, endometrial hyperplasia and neoplasms, intrauterine devices (IUD) and cervical stenosis...

BACKGROUND: Beta-catenin has been implicated in cell-cell communication in a wide variety of developmental and physiological processes. Defective Wnt signaling could result in various cardiac and vascular abnormalities. Little is known regarding Wnt/frizzled pathway in cardiomyocyte apoptosis. METHODS: In this study, the role of β-catenin in apoptosis was investigated in H9c2 cardiomyocytes and primary cardiomyocytes isolated in diabetic Wistar rats. The cardiomyocytes were transfected with porcine cytomegalovirus (pCMV)-β-catenin plasmid in order to overexpress β-catenin...

Elimination of virus-infected cells by cytotoxic lymphocytes is triggered by activating receptors, among which NKG2D and DNAM-1/CD226 play an important role. Their ligands, that is, MHC class I-related chain (MIC) A/B and UL16-binding proteins (ULBP)1-6 (NKG2D ligand), Nectin-2/CD112, and poliovirus receptor (PVR)/CD155 (DNAM-1 ligand), are often induced on virus-infected cells, although some viruses, including human CMV (HCMV), can block their expression. In this study, we report that infection of different cell types with laboratory or low-passage HCMV strains upregulated MICA, ULBP3, and PVR, with NKG2D and DNAM-1 playing a role in NK cell-mediated lysis of infected cells...

Human cytomegalovirus infection (HCMV) has been recently considered as a factor for tumorigenesis. The current study used meta-analytical techniques to explore the prevalence of HCMV in tumor tissues and the relationship between human cytomegalovirus and colorectal cancer (CRC) risk. 11 studies detecting HCMV DNA in tumor tissues were included in meta-analysis. The prevalence rate and odds ratio (OR) were two main parameters. The overall prevalence of human cytomegalovirus DNA in tumor tissues were 27.5% (95% CI = 17...

Because of the widespread use of immunosuppressive drugs, CMV infection is one of the most important causes of morbidity and mortality in patients with haematological malignancies worldwide. The aim of the study was to retrospectively analyse the epidemiology of CMV infection in haematological patients. Between 2008 and 2014, 1238 quantitative CMV DNA detections from plasma specimens were performed. These specimens were collected from 271 patients with haematological malignancy. Patients were grouped on the basis of underlying diseases (lymphoid and myeloid malignancies and other haematological diseases)...

Background: Staff in children's hospitals may run an increased risk of cytomegalovirus (CMV) contact infection leading to a congenital CMV fetopathy during pregnancy. The main risk factor is close contact with inapparent carriers of CMV among infants (<3 years). We therefore examined CMV seroprevalence (SP) and possible risk factors for CMV infection among staff at a children's hospital. Method: In 2014, staff at a metropolitan children's hospital were offered a CMV antibody test in the context of occupational health screening...
