BACKGROUND: Recent in vitro and animal studies have found the proton pump inhibitor (PPI) lansoprazole to be highly active against Mycobacterium tuberculosis. Omeprazole and pantoprazole have no activity. There is no evidence that, in clinical practice, lansoprazole can treat or prevent incident tuberculosis (TB) disease. METHODS AND FINDINGS: We studied a cohort of new users of lansoprazole, omeprazole, or pantoprazole from the United Kingdom Clinical Practice Research Datalink to determine whether lansoprazole users have a lower incidence of TB disease than omeprazole or pantoprazole users...

Cytomegalovirus (CMV) is a type of herpes infection that has a characteristic feature of maintaining lifelong latency within the host cell. CMV manifestations can cover a broad spectrum from fever to as severe as pancytopenia, hepatitis, retinitis, meningoencephalitis, Guillain-Barre syndrome, pneumonia, and thrombosis. Multiple case reports of thrombosis associated with CMV have been reported. Deep vein thrombosis or pulmonary embolism is more common in immunocompetent patients while splenic infarct is more common in immunocompromised patients...

Hyperimmunoglobulin E syndrome (HIES) or Job's syndrome is a rare immunodeficiency disease with less than 200 cases reported worldwide, among which few cases are reported with lesions due to herpes simplex virus (HSV) or human papillomavirus (HPV). This case study presents a rare case of HIES with coinfection of HSV and HPV. A 12-year-old boy, previously diagnosed with HIES, presented with a large conjunctival mass lesion. The presence of HPV in the lesion was confirmed by biopsy and by using the line-probe assay method to detect the HPV genome...

Plasmacytoid dendritic cells (pDCs) were described to accumulate in the skin of patients with psoriasis and to be recruited into the dermis upon allergen challenge in atopic dermatitis. Importantly, activation of pDCs in the skin has been identified as important initiator of psoriasis development. RNase 7 is one of the major antimicrobial peptides (AMP) secreted by keratinocytes and is expressed in significantly higher amounts in lesional skin of patients with atopic dermatitis or psoriasis than in healthy individuals...

BACKGROUND: The varicelloviruses comprise a genus within the alphaherpesvirus subfamily, and infect both humans and other mammals. Recently, next-generation sequencing has been used to generate genomic sequences of several members of the Varicellovirus genus. Here, currently available varicellovirus genomic sequences were used for phylogenetic, recombination, and genetic distance analysis. RESULTS: A phylogenetic network including genomic sequences of individual species, was generated and suggested a potential restriction between the ungulate and non-ungulate viruses...

Herpes simplex virus type 1 (HSV-1) had led to kinds of clinical disorders and became an important cause of morbidity and mortality worldwide, such as herpetic gingivostomatitis in children. Previous studies reported that HSV-1 infection is common and has evolved a variety of mechanisms to evade the immune system, such as dysregulation of miRNAs. However, reports concerning the role of miRNA in HSV-1infection are limited. Here, we report that a host microRNA, miR-373, was significantly upregulated by HSV-1 infection in Hela cells and patients with herpetic gingivostomatitis and it facilitated HSV-1 replication in vitro...

A concise synthetic route to rhamnan oligosaccharides with alternating α-(1→2)/(1→3)-linkages and repeating α-(1→3)-linkages is reported. This synthesis was achieved by iterative α-glycosylation using disaccharide building blocks and through orthogonal coupling between thioglycosides of L-rhamnose. To investigate the detailed structure-activity relationship of rhamnan sulfate from Monostroma nitidum against herpes simplex virus type 2, the synthesized oligosaccharides, bearing different orthogonal protecting groups (i...

The acronym TORCH is used to refer to congenital infections, such as toxoplasmosis, other infections (such as syphillis, varicella-zoster, and parvovirus B19), cytomegalovirus, and herpes simplex virus. The classic findings in patients with TORCH infections include rash in the mother during pregnancy and ocular findings in the newborn. Zika virus has emerged as an important worldwide congenital infection. It fits well with other congenital TORCH infections since there is a rash in the mother and there are commonly ocular abnormalities in the newborn...

The Hey family (also known as Chf, Herp, Hesr, and Hrt) is a set of Hairy/Enhancer of Split-related basic helix-loop-helix type transcription factors. Hey1, Hey2, and HeyL have been identified in mammals. Although Hey proteins are known to regulate cardiovascular development, muscle homeostasis, osteogenesis, neurogenesis, and oncogenesis, their roles in tooth development have been largely obscure. Therefore, this study aimed to clarify detailed spatiotemporal expression patterns of Hey1 and Hey2 in developing molars and incisors of mice by section in situ hybridization...

Infections with Herpes simplex viruses (HSV) belong to the most common human diseases worldwide, resulting in symptoms ranging from painful, but commonly self-limiting lesions of the orofacial or genital tract to severe infections of the eye or life-threatening generalized infections. Frequent HSV-reactivations at the eye may lead to the development of herpetic stromal keratitis, which is one of the major causes of infectious blindness in developed countries. The vast majority of life-threatening generalized infections occur in immunocompromised individuals, such as transplant recipients or patients suffering from advanced human immunodeficiency virus (HIV) infection with concurrent HSV-reactivation...

The therapeutic effect of postherpetic neuralgia (PHN) is often disappointing and challenging. The role of intra-cutaneous injection of local anesthetic and steroids in preventing PHN remains unknown. The purpose of this study was to investigate the effect of a single intra-cutaneous injection of ropivacaine plus methylprednisolone on acute thoracic herpes zoster (HZ) pain intensity and duration, eruptive duration, and PHN incidence. A total of 97 patients with acute thoracic HZ diagnosed 1-7 days after the onset of the rash were randomly assigned to receive either 15 mL of 37...

INTRODUCTION: The Advisory Committee on Immunization Practices recommends a single dose of the live attenuated herpes zoster vaccine in people aged ≥60 years. Because vaccine-induced protection decreases to zero after 10 years, many vaccinated people will soon be subject to an increased risk of the disease. The study objective was to determine the cost effectiveness of a herpes zoster vaccine booster and its optimal timing among immunocompetent adults first vaccinated at aged ≥60 years...

Ruxolitinib exerts immunosuppressive activity that may increase the risk of infectious complications. We performed a systematic review of the literature with the aim of estimating the risk of infections in patients treated with ruxolitinib. Studies were identified by electronic search of MEDLINE and EMBASE database. Differences in the incidence of infectious events between ruxolitinib and comparison groups were expressed as odds ratios (ORs) and 95% confidence intervals (95% CI). Five phase III randomized clinical trials (RCTs) (3 phase IIIa with their extended phase and 2 phase IIIb), 6 phase IV studies and 28 case reports were included in this systematic review...

Kaposi 's sarcoma (KS) is a rare multifocal angioproliferative disease associated with human herpes virus 8 (HHV-8) infection, characterized by cutaneous nodules or plaques especially on the lower limbs. Some skin modifications, such as chronic lymphedema, plantar hyperkeratosis and interdigital desquamation, may be associated with consequent impairment of the local immunosurveillance and increased risk of some bacterial or mycotic infections. With the objective of evaluating if bacterial or mycotic infections in KS patients are supported by different microorganisms compared to control patients, we performed an observational retrospective study, comparing positive cultural swabs of interdigital intertrigo of KS patients with positive cultural swabs of interdigital intertrigo of patients admitted to our dermatologic unit during the last 10 years...

REVIEW
Lata Balakrishnan, Barry Milavetz
It is increasingly clear that DNA viruses exploit cellular epigenetic processes to control their life cycles during infection. This review will address epigenetic regulation in members of the polyomaviruses, adenoviruses, human papillomaviruses, hepatitis B, and herpes viruses. For each type of virus, what is known about the roles of DNA methylation, histone modifications, nucleosome positioning, and regulatory RNA in epigenetic regulation of the virus infection will be discussed. The mechanisms used by certain viruses to dysregulate the host cell through manipulation of epigenetic processes and the role of cellular cofactors such as BRD4 that are known to be involved in epigenetic regulation of host cell pathways will also be covered...
