Abstract
HHV-6A and HHV-6B are found as inherited and chromosomally integrated forms (iciHHV-6A and -6B) into all germinal and somatic cells and vertically transmitted in a Mendelian manner in about 1% of the population. They were occasionally shown to be horizontally transmitted through hematopoietic stem cell transplantation. Here, we present a clinical case of horizontal transmission of iciHHV-6A from donor to recipient through liver transplantation. Molecular analysis performed on three viral genes (7.2 kb) in the recipient and donor samples supports transmission of iciHHV-6A from the graft. Transmission was followed by reactivation, with high viral loads in several compartments. The infection was uncontrollable, leading to severe disease and death, despite antiviral treatments and the absence of resistance mutations. This case highlights the fact that physicians should be aware of the possible horizontal transmission of iciHHV-6 and its consequences in case of reactivation in immunocompromised patients.

Abstract
Human herpesviruses 6A, 6B, and 7 (HHV-6A, HHV-6B, HHV-7) are genetically related to cytomegalovirus. They belong to the Roseolovirus genus and to the Betaherpesvirinae subfamily. They infect T cells, monocytes-macrophages, epithelial cells, and central nervous system cells. These viruses are ubiquitous and are responsible for lifelong chronic infections, most often asymptomatic, in the vast majority of the general adult population. HHV-6B is responsible for exanthema subitum, which is a benign disease of infants. HHV-6A and HHV-6B also cause opportunistic infections in immunocompromised patients: encephalitis, hepatitis, bone marrow suppression, colitis, and pneumonitis. Their etiological role in chronic diseases such as multiple sclerosis, cardiomyopathy, and thyroiditis is still controversial. The pathogenicity of HHV-7 is less clear and seems to be much more restricted. Chromosomal integration of HHV-6A and HHV-6B is transmissible from parents to offspring and observed in about 1% of the general population. This integration raises the question of potential associated diseases and can be a confounding factor for the diagnosis of active infections by both viruses. The diagnosis of HHV-6A, HHV-6B, and HHV-7 infections is rather based on gene amplification (PCR), which allows for the detection and quantification of the viral genome, than on serology, which is mainly indicated in case of primary infection. Ganciclovir, foscarnet, and cidofovir inhibit the replication of HHV-6A, HHV-6B, and HHV-7. Severe infections may thus be treated but these therapeutic indications are still poorly defined.

Abstract
Human herpesvirus-6 (HHV-6) is a betaherpesvirus whose genome may integrate into human chromosomes. Chromosomally integrated HHV-6 (ciHHV-6) may be transmitted vertically from parents to children. HHV-6 DNA has been detected in semen, but its integrated or extrachromosomal status has not yet been characterised. The aim of this study was to determine the prevalence of HHV-6 DNA and to search for ciHHV-6 forms in spermatozoa purified from semen obtained from subjects explored for low fertility. A total of 184 sperm samples were purified using PureSperm(®) . HHV-6 viral load and species identification were performed by real-time polymerase chain reaction. Of 179 sperm specimens analysed, three were positive for HHV-6 (1.7%). Two samples (1.1%) had viral loads of 680 232 and 2 834 075 copies per million spermatozoa, compatible with loads expected for a ciHHV-6 form. The viral load of the third positive sample (73 684 copies per million spermatozoa) was lower than would be expected for ciHHV-6 infection, implying that the HHV-6 DNA detected in spermatozoa corresponds mainly to ciHHV-6. However, viral DNA may also be detected at a low level that is not in favour of the presence of ciHHV-6. Further studies are necessary to determine the origin of detected viral genomes.

Abstract
INTRODUCTION Histiocytic necrotizing lymphadenitis (Kikuchi-Fujimoto disease) is a rare clinical entity characterized by the association of enlarged lymph nodes in the posterior cervical region and fever. The disease is more frequent in young women. CASE REPORT We report a 41-year-old African patient who presented with atypical features of Kikuchi's disease including cutaneous lupus, haemophagocytosis, and lymphocytic meningitis. The ethnic origin and the clinical presentation were initially suggestive of tuberculous meningitis. However, microbiological analyses remained negative, histological findings were suggestive of Kikuchi's disease and HHV6 DNA integration was documented in our patient. CONCLUSION Kikuchi's disease should be suspected in an African patient when lymphocytic meningitis is associated with enlarged cervical lymph nodes, hemophagocytosis and HHV6 DNA integration.

Abstract
Human immunodeficiency viruses (HIV) have a high level of genetic diversity. The outlier variants of HIV type 1 (HIV-1) group O are distantly related to HIV-1 group M. Their divergence has an impact on serological diagnosis, with a risk of false-negative results. In this study, we report 20 failure cases, involving patients with primary or chronic infection, in France and Cameroon between 2001 and 2008. Our results indicate that some assays detected group O infection much less efficiently than others. Two major reasons for these false-negative results were identified: the presence or absence of a group O-specific antigen (and the designed sequence) for the detection of antibodies and the greater envelope variability of group O than of group M strains. This study highlights the complexity of screening for these divergent variants and the need to evaluate test performance with a large panel of strains, due to the extensive diversity of group O variants.

Abstract
The unique phenomenon of human herpesvirus-6 (HHV-6) chromosomal integration (CIHHV-6) may account for clinical drawbacks in transplant setting, being misinterpreted as active infection and leading to unnecessary and potentially harmful treatments. We have investigated the prevalence of CIHHV-6 in 205 consecutive solid organ (SO) and allogeneic stem cell transplant (alloSCT) Italian patients. Fifty-two (38.5%) of 135 solid organ transplant (SOT) and 16 (22.8%) of 70 alloSCT patients resulted positive for plasma HHV-6 DNA by real-time polymerase chain reaction. Seven SOT and three alloSCT patients presented HHV-6-related diseases, requiring antivirals. Two further patients (0.9%) were identified, presenting high HHV-6 loads. The quantification of HHV-6 on hair follicles disclosed the integrated state, allowing the discontinuation of antivirals. Before starting specific treatments, CIHHV-6 should be excluded in transplant patients with HHV-6 viremia by the comparison of HHV-6 loads on different fluids and tissues. Pretransplantation screening of donors and recipients may further prevent the misdiagnosis of CIHHV-6.

Abstract
Kits for the detection of HIV infection are in vitro-diagnostic medical devices and are subject to special regulation to be marketed in the European Community. Before 1998, the Agence française de sécurité sanitaire des produits de santé was responsible for evaluating the new kits before allowing their marketing in France. The publication in the Official Journal of the European Community (L331 of December 7, 1998) of the European directive 98/79/CE of October 27, 1998 on in vitro diagnostics medical devices has changed the procedure for marketing approval of these kits in Europe. The aim of this review is to present the relevant conformity assessment procedures and its latest updates.

Abstract
BACKGROUND The emergence of human herpesvirus 6 (HHV-6) as a human pathogen led to the possibility of specific therapy against HHV-6 and the development of standardized susceptibility assays of HHV-6 to antivirals. METHODS We have developed a flow cytometry method to analyze the multiplication of the HST strain of human herpesvirus 6 (HHV-6) variant B in vitro using monoclonal antibodies specific to virus proteins. This method was subsequently used to determine the sensitivity of HST multiplication in MT4 cells to four antiviral compounds of three different classes: acyclovir (ACV) and ganciclovir (GCV), two acyclic guanosine analogs; cedofovir (CDV), an acyclic nucleoside phosphonate; and phosphonoformic acid (PFA), a pyrophosphate analog. RESULTS The 50% inhibitory concentrations (IC(50)) of ACV, GCV, CDV, and PFA determined by flow cytometry assay were 25.3, 6.4, 0.95, and 6.0 microM, respectively (5.7, 1.6, 0.3, and 1.8 microg/ml, respectively). These data together with the results of cytotoxicity assays confirmed the high efficiency and selectivity of CDV and PFA against HHV-6 B in vitro, suggested by previous results. CONCLUSIONS Our flow cytometric assay appeared as a reproducible specific method to characterize HHV-6 susceptibility to antiviral compounds. It can be considered as a convenient alternative to the other immunologic and DNA hybridization assays used for that purpose.

Abstract
BACKGROUND Human herpesviruses (HHVs) 6 and 7 are recently discovered betaherpesviruses. Although HHV-6 has been associated with disordered hematopoiesis in bone marrow transplant recipients, little information is available on the presence of both viruses in the bone marrow from healthy subjects. METHODS We detected HHV-6 and HHV-7 DNA by means of polymerase chain reaction in bone marrow and peripheral blood samples from 18 healthy subjects who underwent total hip arthroplasty. RESULTS Genomic HHV-6 and HHV-7 DNA were detected in 11% and 67% of the blood samples, respectively, and in 28% and 50% of the bone marrow samples, respectively. CONCLUSIONS Both viruses may be present in the bone marrow without hematopoiesis disorder and can be transmitted through bone marrow infusion. Therefore, the causative role of these two viruses in some bone marrow diseases cannot be inferred simply from the detection of their genome in bone marrow by means of polymerase chain reaction.

Abstract
We had previously described six distinct alleles of the glycoprotein B (gB) gene of human herpesvirus 7 (HHV-7). The genetic changes corresponding to these alleles did not affect gB gene transcription or translation in in vitro assays. The study of distinct HHV-7-positive human samples showed preferential associations of some gB alleles with some alleles of two other genes, distantly located on the HHV-7 genome, coding for the phosphoprotein p100 (p100) and the major capsid protein (MCP). Two allele combinations, corresponding to 44 and 31% of the samples studied, respectively, were interpreted as the genetic signatures of two major prototype HHV-7 variants.

Abstract
As for other herpesviruses, glycoprotein B (gB) of human herpesvirus 7 (HHV-7) is believed to play a major role in virus infection and as a target of the host immunogenic response. Using nested PCR, we amplified the whole HHV-7 gB gene from 108 human peripheral blood mononuclear cell samples and studied its variability. By means of restriction fragment length polymorphism (RFLP) analysis, three distinct patterns, designated I, II, and III, were defined and detected at frequencies of 93, 5, and 2%, respectively. Determination of the nucleotide sequence allowed us to recognize five critical positions in the gB gene with six specific combinations of point changes at these positions. These combinations were gB alleles A, B, C, D, E, and F. Alleles D and E corresponded to RFLP patterns II and III, respectively, while the other four alleles corresponded to RFLP pattern I. Identical gB alleles were detected in serial samples as well as in paired samples of blood and saliva from the same individuals, except for one case. In contrast, the distribution of gB alleles differed according to the geographical origin of the human samples: C was the most frequent allele in both African and Caribbean samples, whereas F was the most frequent allele in European ones. Although none of the allele-specific nucleotide changes induced any modification at the protein level, the definition of gB alleles provided convenient viral markers for the study of both HHV-7 infections and human population genetics.

Abstract
BACKGROUND Human herpesvirus-6 (HHV-6) has been implicated in bone marrow suppression, interstitial pneumonitis, and fatal meningoencephalitis in bone marrow transplant (BMT) recipients. METHODS We describe the case of a woman with acute myeloid leukemia in second remission who developed febrile meningoencephalitis 8 months after a second unrelated BMT. RESULTS Computed tomography and magnetic resonance images of the brain were nonspecific. Analysis of cerebrospinal fluid (CSF) revealed lymphocytosis and an increased protein level. Using polymerase chain reaction methods, HHV-6 was the only pathogen detected in CSF, peripheral blood mononuclear cells, and bone marrow. The patient was treated with ganciclovir and foscarnet for 3 months. All clinical manifestations resolved and HHV-6 polymerase chain reaction analysis of CSF became negative 40 days after the beginning of antiviral treatment. CONCLUSIONS This observation strongly suggests that HHV-6 should be sought in BMT patients with neurological complications and that HHV-6 meningoencephalitis may respond to ganciclovir and foscarnet therapy.

Abstract
Human cytomegalovirus (HCMV) is a well-known opportunistic agent that reactivates in human immunodeficiency virus (HIV)-seropositive subjects. Human herpesvirus 6 (HHV-6) and HHV-7 were discovered recently and, like HCMV, belong to the Betaherpesvirinae subfamily. We looked for the presence of HCMV, HHV-6, and HHV-7 by PCR with saliva and urine samples from 125 HIV-seropositive patients at different stages of HIV infection and with saliva and urine samples from 29 HIV-seronegative subjects. All three viruses were frequently detected in the saliva (overall rates of detection, 61, 43, and 63% for HCMV, HHV-6, and HHV-7, respectively) with no correlation with the stage of immune deficiency. In contrast, HCMV was detected in urine much more frequently than the two other herpesviruses (overall rates of detection, 37, 2, and 6.5% for HCMV, HHV-6, and HHV-7, respectively) and was associated with immune deficiency. This suggests that these three genetically related viruses differ from each other with regard to replication in the urinary tract.
