Herpes simplex virus 1 (HSV-1) has extensive interactions with the host DNA damage response (DDR) machinery that can be either detrimental or beneficial to the virus. Proteins in the homologous recombination pathway are known to be required for efficient replication of the viral genome, while different members of the classical non-homologous end-joining (c-NHEJ) pathway have opposing effects on HSV-1 infection. Here, we have investigated the role of the recently-discovered c-NHEJ component, PAXX (Paralogue of XRCC4 and XLF), which we found to be excluded from the nucleus during HSV-1 infection...

Resolution of virus infections depends on the priming of virus-specific CD8(+) T cells by dendritic cells (DC). While this process requires MHC class I-restricted antigen presentation by DC, the relative contribution to CD8(+) T cell priming by infected DC is less clear. We have addressed this question in the context of a peripheral infection with herpes simplex virus type 1 (HSV). Assessing the endogenous, polyclonal HSV-specific CD8(+) T cell response, we found that effective in vivo T cell priming depended on the presence of DC subsets specialized in cross-presentation while Langerhans cells and plasmacytoid DC were dispensable...

Neuromyelitis optica is a severe autoimmune demyelinating disease; however, the trigger for autoimmunity in an individual patient is unclear. Here, we report the case of a 48 year old female presenting with longitudinally extensive transverse myelitis in the cervical region of the spinal cord two weeks post herpes zoster infection in right C6 dermatome. Though post herpetic myelitis was provisionally diagnosed, serological evaluation revealed aquaporin-4 antibody positivity, confirming the diagnosis of neuromyelitis optica spectrum disorder...

Multiple Sclerosis (MS) is an autoimmune disease in which lymphocytes target putative myelin antigens in the CNS, causing inflammation and neurodegeneration. Fingolimod (FTY720) is an immunosuppressive drug used as a second line therapy for relapsing forms of MS due to its safety profile and good response to treatment. Despite its safety, there are still concerns about the possibility of Fingolimod being linked to the development of opportunistic infections like disseminated varicella zoster infections and herpes simplex encephalitis...

INTRODUCTION: Limited studies and differential risk behaviours among men who have sex with men(MSM) in Africa calls for population specific studies. We present results from the largest integrated bio-behavioural survey among MSM in Africa to inform programming. METHODS: This was a cross-sectional study utilizing respondent driven sampling to recruit MSM aged 18 and above. Data on socio-demographic characteristics and HIV-related risks were collected and all participants were tested for HIV, Herpes Simplex Virus Type-2 (HSV-2), Hepatitis-B Virus (HBV) and Syphilis...

Tofacitinib (Xeljanz(®)) is a potent, selective JAK inhibitor that preferentially inhibits Janus kinase (JAK) 1 and JAK3. In the EU, oral tofacitinib 5 mg twice daily is indicated for the treatment of moderate to severe active rheumatoid arthritis (RA) in adult patients who have responded inadequately to, or who are intolerant of, one or more DMARDs. Several clinical studies of ≤ 24 months' duration showed that tofacitinib monotherapy (as first- or second-line treatment) and combination therapy with a conventional synthetic DMARD (csDMARD; as second- or third-line treatment) was effective in reducing signs and symptoms of disease and improving health-related quality of life (HR-QOL), with benefits sustained during long-term therapy (≤ 96 months)...

BACKGROUND: Recently, we published data suggesting a mutualistic relationship between HSV-1 and Candida. albicans; in particular: (a) HSV-1 infected macrophages are inhibited in their anti-Candida effector function and (b) Candida biofilm protects HSV-1 from inactivation. The present in vitro study is aimed at testing the effects of Candida biofilm on HSV-1 sensitivity to pharmacological and physical stress, such as antiviral drugs (acyclovir and foscarnet) and laser UVA1 irradiation...

BACKGROUND: Varicella zoster virus (VZV) causes varicella and herpes zoster. These vaccine preventable diseases are common globally. Most available data on VZV epidemiology are from industrialised temperate countries and cannot be used to guide decisions on the immunization policy against VZV in Africa. This systematic review aims to review the published data on VZV morbidity and mortality in Africa. METHODS: All published studies conducted in Africa from 1974 to 2015 were eligible...

OBJECTIVES: To evaluate efficacy/safety of baricitinib for rheumatoid arthritis (RA) in Japanese subpopulations from four phase 3 studies, and assess whether results in these subpopulations are consistent with the overall study populations. METHODS: Subgroup analyses (394 patients) of four phase 3 randomized controlled trials: RA-BEGIN [no or limited treatment with disease-modifying antirheumatic drugs (DMARDs)], RA-BEAM [inadequate response (IR) to methotrexate], RA-BUILD [IR to conventional synthetic DMARDs (csDMARDs)], and RA-BEACON (IR to tumor necrosis factor inhibitors receiving csDMARDs)...

BACKGROUND: Peripheral blood progenitor cell (PBPC) mobilization with chemotherapy in addition to Granulocyte-Colony Stimulating Factor (G-CSF) improves cell collection compared to G-CSF alone; however, it is associated with increased risk of neutropenic fever (NF). METHODS: We analyzed risk factors for post-priming NF and NF association with autologous stem cell transplant outcomes. Between 1998 and 2008, 593 adult patients with lymphoma underwent PBPC mobilization with etoposide and G-CSF...

INTRODUCTION: Amenamevir (ASP2151) is a nonnucleoside human herpesvirus helicase-primase inhibitor that was approved in Japan for the treatment of herpes zoster (shingles) in 2017. This article reports the results of two clinical trials that investigated the effects of renal and hepatic impairment on the pharmacokinetics of amenamevir. METHODS: These studies were phase 1, open-label, single-dose (oral 400 mg), parallel-group studies evaluating the pharmacokinetics, safety, and tolerability of amenamevir in healthy participants and participants with moderate hepatic impairment and mild, moderate, and severe renal impairment...

A 15-year-old healthy boy developed acute, rapidly progressing visual loss in left eye following herpes zoster dermatitis, with a combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO), along with optic perineuritis. Laboratory tests were negative. Despite an empirical, intensive antiviral treatment with systemic corticosteroids, and vision could not be restored in the affected eye. Herpes zoster dermatitis, in an immunocompetent individual, may be associated with a combined CRAO and CRVO along with optic perineuritis, leading to profound visual loss...

Prashant Garg, Paavan Kalra, Joveeta Joseph
The purpose of the study is to describe epidemiology, clinical features, diagnosis, and treatment of Acanthamoeba keratitis (AK) with special focus on the disease in nonusers of contact lenses (CLs). This study was a perspective based on authors' experience and review of published literature. AK accounts for 2% of microbiology-proven cases of keratitis. Trauma and exposure to contaminated water are the main predisposing factors for the disease. Association with CLs is seen only in small fraction of cases. Contrary to classical description experience in India suggests that out of proportion pain, ring infiltrate, and radial keratoneuritis are seen in less than a third of cases...

OBJECTIVES: To describe the epidemiology of neonatal herpes and its risk factors, clinical and paraclinic manifestations, propose guidelines for a newborn at risk of neonatal herpes, describe treatment modalities, describe post-natal transmission and its prevention. METHODS: Bibliographic search from Medline, Cochrane Library databases and research of international clinical practice guidelines. RESULTS: Neonatal herpes is rare (about 20 cases per year in France) and mainly due to HSV 1 (level of evidence LE3)...

OBJECTIVE: To provide guidelines for the management of woman with genital herpes during pregnancy or labor and with known history of genital herpes. METHODS: MedLine and Cochrane Library databases search and review of the main foreign guidelines. RESULTS: Genital herpes ulceration during pregnancy in a woman with history of genital herpes correspond to a recurrence. In this situation, there is no need for virologic confirmation (Grade B). In case of recurrent herpes during pregnancy, antiviral therapy with acyclovir or valacyclovir can be administered but provide low efficiency on duration and severity of symptoms (Grade C)...
