The biological actions of LIGHT, a member of the tumor necrosis factor superfamily, are mediated by the interaction with lymphotoxin-beta receptor (LTbetaR) and/or herpes virus entry mediator (HVEM). Previous study demonstrated high-level expressions of LIGHT and HVEM receptors in atherosclerotic plaques. To investigate the role of LIGHT in the functioning of macrophages and vascular smooth muscle cells (VSMC) in relation to atherogenesis, we determined the effects of LIGHT on macrophage migration and VSMC proliferation. We found LIGHT through HVEM activation can induce both events. LIGHT-induced macrophage migration was associated with activation of signaling kinases, including MAPKs, PI3K/Akt, NF-kappaB, Src members, and FAK. Proliferation of VSMC was also shown relating to the activation of MAPKs, PI3K/Akt, and NF-kappaB, which consequently led to alter the expression of cell cycle regulatory molecules. Down-regulation of p21, p27, and p53, and inversely up-regulation of cyclin D and RB hyper-phosphorylation were demonstrated. In conclusion, LIGHT acts as a novel mediator for macrophage migration and VSMC proliferation, suggesting its involvement in the atherogenesis.

The clinical value of aciclovir, oral or topical, in the episodic treatment of recurrent herpes virus infection is limited. Betadine (povidone-iodine) could provide a cheap, effective alternative for managing symptomatic recurrences. We describe a case where povidone-iodine was used successfully to treat a recurrence of genital herpes simplex and review the literature supporting povidone-iodine in the treatment of genital tract infections.

We report on a patient from a London clinic, (a Jamaican heterosexual man known to have herpes) who has donovanosis and syphilis in a single genital ulcer. The case highlights the importance of careful clinical examination of genital ulcers.

Of the 1418 patients with STDs, who attended the STD clinic between January 1996 to December 2000, 50 (3.4%) were children below 14 years of age. Boys (29) were more than girls (21). Syphilis was the most common STD found in these children (46.8%), followed by vulvo-vaginal candidiasis (19.2%), condylomata acuminata (10.6%), gonorrhoea (8.5%), herpes progenitalis (6.4%), chancroid (4.3%), perianal candidosis and perianal molluscum contagiosum (2.1 % each). Three children had more than one STD. A history of sexual abuse could be elicited in 30 children (60%), none of the children were positive of HIV. All children with symptoms pertaining to their genitourinary system should be evaluated thoroughtly for sexual abuse.

The objectives of this study were to assess the nature and effect of stigma on disclosure of diagnosis to sexual partners among those with problematic disease. Data from questionnaires and semistructured interviews were collected and analysed. Data regarding anxiety were also collected using a validated tool. Ethical approval was received from the Chelsea and Westminster Healthcare National Health Service (NHS) Trust. Disclosure of diagnosis tended to occur in the context of established relationships. Herpes-related stigma was associated with non-disclosure of diagnosis to sexual partners. The point prevalence of moderate to severe anxiety in this sample was 32%. The use of suppressive medication did not affect anxiety scores. In conclusion, the reaction to a diagnosis of genital herpes is influenced by a socially constructed understanding and the decision to disclose or not is influenced by this. Stigma is a barrier to disclosure of genital herpes diagnosis. Management strategies aimed at encouraging disclosure to partners must address perceived stigma.

Both herpes simplex virus type 2 (HSV-2) seroprevalence and the proportion of HSV-1 genital ulcers are increasing in industrialized countries. The consequences of these epidemiological changes, in pregnant women in France, for both the genital shedding of HSV and vertical transmission, have been poorly evaluated. The HSV-1 and HSV-2 seroprevalence and the rate of subclinical genital shedding of herpes close to delivery were evaluated in pregnant women, with no history of genital herpes, living in the East Paris suburban area. HSV-2 antibody prevalence of 26% was significantly associated with country of origin and was higher than that reported in 2002 in French women from the general population (18%). HSV-2 and HSV-1 genital reactivations were observed in 10% of HSV-2 seropositive and in 4% of HSV-1 seropositive and HSV-2 seronegative women, respectively. The high rates of HSV-2 seropositivity and subclinical herpes genital shedding observed in this study should be considered to promote a national survey in pregnant women to propose strategies to prevent the spread of HSV within the population and to the neonate.

There is very little knowledge about how herpes simplex virus (HSV) seropositivity of HIV-positive mothers could complicate the occurrence of neonatal herpetic disease, in the absence of genital ulcers, in this group of patients. We present a case of fatal disseminated neonatal herpes infection in a baby, born to a HIV-positive patient, and wish to discuss the potential need for changes in the management of this group of patients during pregnancy. Disseminated HSV disease is a rare, yet serious condition in newborns of HSV-infected mothers, and women with HIV infection have shown to frequently shed more HSV DNA in their genital secretions, even in the absence of active herpetic ulcers. This is the first case report of this rare association and, as a result, the evidence in support of our hypothesis has been extrapolated from other studies.

Kaposi's sarcoma (KS) is strongly associated with KS herpes virus infection, and inflammation plays an important role in this disease. We have shown that human KS biopsy-derived SLK cells, which are of endothelial origin and form KS-like tumors in nude mice, express the viral RNA pattern recognition receptors Toll-like receptor 3 (TLR3), retinoic acid-inducible gene-I (RIG-I), and melanoma-differentiation-associated gene 5 (MDA5). Furthermore, SLK cells have enhanced release of IL-6, IL-8 (CXCL8), RANTES (CCL5), and IP-10 (CXCL10) proteins in response to the synthetic viral RNA analog poly(I:C). SiRNA knockdowns demonstrated that TLR3 mediates this inflammatory response to poly(I:C) in SLK cells. Furthermore, knockdown of the RNA receptor RIG-I resulted in enhanced chemokine release, in a TLR3 pathway-dependent manner. Thus, exposure of KS cells to viral RNA ligands can result in a TLR3-mediated increase in the secretion of inflammatory proteins associated with KS cell growth that may contribute to disease.

The transmembrane protein gp130 acts as the signal transducing receptor subunit for interleukin-6 type cytokines, including viral interleukin-6, which is encoded by the Kaposi's sarcoma-associated herpes virus. Viral interleukin-6 has been shown to mimic human IL-6 functions, including activation of the JAK1 and STAT1/3 signaling pathways. Based on the crystal structure of three extracellular domains of gp130 in complex with viral interleukin-6, we have designed and synthesized a range of assembled peptides that mimic the sequentially discontinuous binding site of gp130 for viral interleukin-6. These peptides, which present the three binding site fragments of gp130 in a nonlinear, discontinuous fashion, were shown to inhibit the interaction of gp130 with viral interleukin-6, as well as the stimulation of viral interleukin-6-induced cell proliferation. These results validate the concept of synthetic mimicry of discontinuous protein-binding sites through assembled peptides, and the use of such molecules as modulators of protein-ligand interactions.

Primary effusion lymphoma (PEL) is a unique form of non-Hodgkin lymphoma, mainly met in severely immunocompromised, HIV-positive patients. PEL is aetiologically related to human herpes virus-8 (HHV-8) and it usually presents as a lymphomatous body cavity effusion in the absence of a solid tumour mass. Recently, cases of HIV-positive patients with HHV-8-positive solid tissue lymphomas, not associated with an effusion, have been reported (solid variant of PEL). The prognosis of PEL is reported to be poor. We report a case of an HIV-positive patient with a typical solid variant of PEL without effusion. Interestingly, his disease developed while being on stable antiretroviral therapy (ART) with high CD4 counts. He had a relatively long survival with chemotherapy and ART.
