Abstract
As the loss of HBsAg during treatment of chronic hepatitis delta (CHD) is mandatory for definitive clearance and durable response, the optimal target of therapy should be complete response (CR), defined as loss of HDV RNA and HBsAg, plus development of anti-HBs. The optimal treatment duration of CHD is not well established. We present 2 cases of patients with CHD cirrhosis who were treated with prolonged Peg-IFNα-2a + tenofovir disoproxil fumarate until HBsAg loss, and who achieved CR after 46 and 55 months of treatment respectively. A personalized approach and prolonged treatment duration determined by HBsAg loss may increase the likelihood of CR in CHD.

Abstract
We report an acute Coxsackievirus B3 (CVB3)-induced meningo-cerebellitis in an immunocompetent adult patient. CVB3 has a global distribution and is the most common Enteroviruses cause of myocarditis and sudden cardiac death. To our knowledge, CVB3 is exceedingly rare as causes of meningo-encephalitis in immunocompetent adults, whereas some cases have been reported in neonates due to perinatal acquired infections or in immunocompromised patients.

Abstract
Major 5'terminally deleted (5'TD) group-B enterovirus (EV-B) populations were identified in heart biopsies of patients with fulminant myocarditis or dilated cardiomyopathy suggesting that these 5'TD forms are key drivers of host-cell interaction in EV cardiac infections. To date, early emergence of EV-B 5'TD forms and its impact on type 1 IFN response during acute myocarditis remains unknown. Using quantitative RACE-PCR assay, we identified major EV-B 5'TD RNA populations in plasma or heart samples of acute myocarditis cases. Deletions identified within the 5' non-coding region of EV-B populations only affected secondary-structural elements of genomic RNA domain I and were distinguished in two major groups based on the extent of RNA structural deletions. Proportions of these two respective EV-B 5'TD population groups were positively or negatively correlated with IFN-β levels in plasma samples of myocarditis patients. Transfection of synthetic CVB3/28 RNAs harboring various 5'terminal full-length or deleted sequences into human cultured cardiomyocytes demonstrated that viral genomic RNA domain I possessed essential immunomodulatory secondary-structural elements responsible for IFN-β pathway induction. Overall, our results highlight the early emergence of major EVB-TD populations which deletions affecting secondary-structures of RNA domain I can modulate innate immune sensing mechanisms in cardiomyocytes of patients with acute myocarditis.

Abstract
BACKGROUND Autopsies, including minimally invasive autopsies, are a powerful tool for determination of the cause of death. When a patient dies from an infection, microbiology is crucial to identify the causative organism. Post-mortem microbiology (PMM) aims to detect unexpected infections causing sudden deaths; confirm clinically suspected but unproven infection; evaluate the efficacy of antimicrobial therapy; identify emergent pathogens; and recognize medical errors. Additionally, the analysis of the thanatomicrobiome may help to estimate the post-mortem interval. AIMS The aim was to provide advice in the collection of PMM samples and to propose sampling guidelines for microbiologists advising autopsy pathologists facing different sudden death scenarios. SOURCES A multidisciplinary team with experts in various fields of microbiology and autopsies on behalf of the ESGFOR (ESCMID - European Society of Clinical Microbiology and Infectious Diseases - study group of forensic and post-mortem microbiology and in collaboration with the European Society of Pathology) developed this narrative review based on a literature search using MedLine and Scopus electronic databases supplemented with their own expertise. CONTENT These guidelines address measures to prevent sample contamination in autopsy microbiology; general PMM sampling technique; protocols for PMM sampling in different scenarios and using minimally invasive autopsy; and potential use of the evolving post-mortem microbiome to estimate the post-mortem interval. IMPLICATIONS Adequate sampling is paramount to identify the causative organism. Meaningful interpretation of PMM results requires careful evaluation in the context of clinical history, macroscopic and histological findings. Networking and closer collaboration among microbiologists and autopsy pathologists is vital to maximize the yield of PMM.

Abstract
A young man presented with a history of myocarditis with palpitations and dizziness. He had implantation of a loop recorder that showed repetitive short episodes of VT. In addition, there were fragmented potentials immediately following the large and sharp electrograms (EGMs) before as well as after episodes of VT suggesting an Epsilon wave. This signal can be observed in multiple cardiac conditions including coronary artery disease. It was originally recorded on the epicardium as well as on the endocardium. However, in ARVD it can be defined as an electric signal observed after the end of the QRS complex in the right as opposed to the left precordial leads (difference ≥ 25 ms). It can also be an aid to the diagnosis of patients with ARVD who have other signs or symptoms suggesting ARVD including episodes of myocarditis. This potential consists of a slurring at the end of the QRS complex or an independent potential after the return to the isoelectric line. It can be better observed by increasing amplification of the ECG tracing as well as double speed using the Fontaine lead system. Epsilon wave too small to be recorded on the standard ECG can be extracted by Signal Averaging ECG SAECG).

Abstract
PURPOSE To investigate the contribution of microbial analysis in the diagnosis and management of severe microbial keratitis. MATERIAL AND METHOD This is a monocentric retrospective study at the University Hospital of Reims from January 2012 to December 2014. Corneal scrapings with infectious keratitis were subjected to routine bacterial and fungal culture. PCR was also performed to detect various viral DNA (VZV, CMV, EBV, HSV 1 & 2, adenovirus) and Acanthamoeba sp. DNA. All contact lens cases were analyzed if available. RESULTS One hundred and six patients were hospitalized, including 30 contact lens wearers (28.3%). Sixty-four bacterial cultures were positive (68%). Twenty-five different bacterial species were identified with a majority of gram-positive bacteria (67.92%). Among contact lens wearers, the initial VA was better than non-wearers (P=0.0004) and 37% of bacteria identified (a plurality) were gram positive. Of 11 contact lens case analyzed, in only one case (3.3%) did the result correlate with the corneal culture. Only 9 samples from the 323 viral DNA extractions and real time PCR were positive (2.8%); 7 were HSV1. No prior antiviral therapy had been started. Fungal culture was positive in 2 of the 97 corneal samples taken and 63.6% of the contact lens cases (7/11 cases). Only one of the 40 Acanthamoeba sp. PCR's was positive. CONCLUSION The systematic performance of microbiological investigations is a good diagnostic approach given the polymorphism of clinical presentations of corneal ulcers, which can sometimes be extremely misleading. Culture of contact lens cases appears ineffective for the detection and determination of the causative microorganism. The high incidence of Staphylococcus in bacterial keratitis and the prevalence of infections with gram-positive bacteria in contact lens wearers were noted.

Abstract
7551 Background: The HRS derive from germinal-center B-cells, potential sites for latency and reactivation of JCV in immunosuppressed individuals. Replication of human polyomaviruses (JC, BK, SV40) and EBV was assessed in Hodgkin (HL) and B cell non-Hodgkin (B-NHL) lymphomas. Methods: FISH, immunohistochemistry for oncogenic proteins, PCR and DNA sequencing to identify polyomaviruses and EBV on involved nodes and in PBL before, during and after treatment (N = 73 HL, 91 B-NHL). Controls were 30 healthy donors, 70 solid tumors and 14 acute leukemia patients. Results: using FISH, JCV and EBV DNA were detected in all lymphoma nodes. High genome copy number of JCV and EBV were present in 60% and 63%, respectively, in HL patients versus 11% and 14% in B-NHL patients (P < 10−6; P < 10−5). Using nest-PCR, JCV DNA sequencing after laser capture microdissection identified the presence and specificity of JCV sequences in HRS. T antigen and LMP1 co-expression, in 34% of HRS, was associated with early HL relapse (P < 10−4), particularly in young patients (P < 10−5). Only in HL patients PBL, genome copy number of JCV increased significantly during treatment (42%). Rogue cells (cultured lymphocytes with multiple complex chromosomal aberrations indicative of genomic instability) appeared in 40% of patients, and correlated with relapse (p < 10−4). The same JCV sequences were found in tumor cells and PBL of HL patients. Co-genomic replication of EBV and JCV was highly correlated in lymph nodes and in PBL in HL. Conclusions: JCV genomic replication was detected for the first time in HRS, and associated to rogue cell emergence in PBL. Co-detections of JCV and EBV genomic replication in HRS and PBL are associated with relapse, especially in young patients. HRS and PBL JCV/EBV infections are linked and worth further studies. No significant financial relationships to disclose.

Abstract
The detection of traces of semen in cervicovaginal secretions (CVS) from sexually active women practicing unprotected sex is a prerequisite for the accurate study of cervicovaginal immunity. Two semen markers, the prostatic-specific antigen (PSA) and the Y chromosome, were detected in parallel in CVS obtained by a standardized vaginal washing of consecutive women attending the principal medical center for sexually transmitted diseases of Bangui, Central African Republic. PSA was detected by immunoenzymatic capture assay in the cell-free fraction of CVS, and the Y chromosome was detected by a single PCR assay of DNA extracted by silica from the cell fraction (Y PCR). Fifty (19%) cell-free fractions of the 264 beta-globin-positive CVS samples were positive for PSA, and 100 (38%) cell fractions of the CVS samples were positive for the Y chromosome. All the 50 (19%) PSA-containing CVS samples were also positive for the Y chromosome. Fifty (19%) CVS samples were positive only for the Y chromosome, with no detectable PSA. The remaining 164 (62%) CVS samples were both PSA and Y chromosome negative. These findings demonstrate that CVS from sexually active women may contain cell-associated semen residues unrecognized by conventional immunoenzymatic assays used to detect semen components. The detection of cell-associated male DNA with a highly sensitive and specific procedure such as Y PCR constitutes a method of choice to detect semen traces in female genital secretions.

Abstract
Two commercially available hypersensitive assays for human immunodeficiency virus type 1 (HIV-1) RNA quantitation, AMPLICOR HIV-1 Monitor Test 1.5 and Quantiplex HIV RNA 3.0, were compared to detect and quantify HIV-1 RNA in the cell-free fraction of cervicovaginal secretions collected by vaginal washing. Three panel specimens were used: pooled cervicovaginal secretions spiked with HIV-1 subtype A or HIV-1 subtype B and cervicovaginal lavages from HIV-positive and HIV-negative women. Compared to the AMPLICOR HIV-1 Monitor Test 1.5 assay, the Quantiplex HIV-1 3.0 assay yielded higher estimates of HIV-1 RNA concentrations in several tested samples spiked with HIV-1 RNA subtype A, as well as subtype B, particularly samples containing low amounts of HIV-1 RNA. The sensitivity and specificity of the AMPLICOR HIV-1 Monitor Test 1.5 assay were 93 and 100%, respectively; the sensitivity and specificity of the Quantiplex HIV RNA 3.0 assay were 97 and 50%, respectively. In conclusion, in quantifying HIV-1 RNA in cervicovaginal secretions, the Quantiplex HIV RNA 3.0 may lack specificity, and the AMPLICOR HIV-1 Monitor Test 1.5 assay, although highly specific, may lack sensitivity.

Abstract
A Herpes Consensus allows the simultaneous detection of 6 human herpesviruses: herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), human cytomegalovirus (HCMV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), and human herpes virus 6 (HHV-6). This technique was used first to examine retrospectively 100 DNA extracts from 95 CSF and 5 aqueous fluids, prepared by treatment by saturated NaCl followed by ethanol precipitation (n = 63) or by simple boiling (n = 37) and stored at -80 degrees C, and secondly to test prospectively 38 CSF samples for which two DNA extracts were prepared with commercially available DNA extraction kits. In all cases, the results were compared with those of an "in-house" PCR. Concordant results between both PCR and the Herpes Consensus techniques were obtained in 61 of 63 DNA extracts prepared by treatment by saturated NaCl (97%) and in only 31 of 37 boiled samples (84%). Both commercially available methods of DNA extraction examined appear to be suitable for Herpes Consensus PCR, although they cannot remove completely PCR inhibitors that must be sought in case of negative results. This preliminary study shows that the Herpes Consensus method should be of value for rapid diagnosis of herpesvirus infections on condition that it is performed on purified DNA extracts.

Abstract
BACKGROUND There are still discrepancies in the association of enterovirus and myocardial disease, partially due to lack of data on the detection of virus antigens in tissues. It is desirable to localize enteroviral antigens so as to establish a link between the two and to study mechanisms of virus persistence. METHODS AND RESULTS Nineteen fixed explanted or postmortem myocardial samples were obtained from patients with myocarditis or dilated cardiomyopathy (DCM). Control samples were collected from 11 subjects who had died accidentally or of noncardiovascular disease. Viral antigen was detected by an improved immunohistochemical technique using an enterovirus group-specific antibody to viral capsid protein VP1. Nine of 11 myocarditis cases (81.8%) and 6 of 8 DCM cases (75%) were positive. Signals were localized in the cytoplasm of myocytes. Intense immunostaining was observed in acute myocarditis, whereas VP1 was detected in scattered myocytes in chronic myocarditis or DCM. Enteroviral RNA was detected in 6 of 11 myocarditis samples (54.5%) and 3 of 8 DCM samples (37.5%) by the reverse transcription-nested polymerase chain reaction, correlating with antigen detection (kappa=0.6+/-0.21). Neither viral antigen nor RNA was detected in any controls. CONCLUSIONS Our findings demonstrate a direct link between enterovirus infection and some myocarditis or DCM cases. The pattern of VP1 detection may correlate with disease stage and severity. The data suggest that viral protein synthesis may be involved in persistent enterovirus infection in the pathogenesis of DCM.

Abstract
Ninety-eight samples from 80 cases of spontaneous abortions after fetal death or hydrops fetalis from 12,000 pregnant women were examined using PCR. DNA was extracted from amniotic fluid, fetal blood, ascitic fluid and fetal biopsies or placenta specimens using QIA amp kits (QIAGEN). A 270-bp length fragment located within the B19 gene NS1 was amplified using PCR followed by electrophoresis and southern-blot hybridization assay using a horseradish peroxidase-labelled probe and chemiluminescence detection. This assay was able to detect 1 to 10 DNA copies in a 10 microliters sample. Parvovirus B19 was identified in 11 cases (14% of fetal hydrops; 1 case for 1,100 pregnancies). Amniotic fluid was the most common and reliable sample to assess the diagnosis. Gestational age ranged from 17 to 28 weeks (mean 23 weeks). IgM antibodies were detected in 3 maternal sera, 2 patients of which reported an exposure to B19 infection during pregnancy. In 2 cases, intrauterine blood transfusions led to the cessation of symptoms and to birth of normal babies.

Abstract
Human parvovirus B19 primary infection during pregnancy is responsible for 27% of non autoimmune hydrops fetalis. Parvovirus B19 antigen detection and parvovirus B19 IgM and IgG antibody determination using enzyme immunoassays are not reliable for diagnostic purposes and lack of specificity. Parvovirus B19 DNA detection in amniotic fluid, fetal blood, ascitic fluid, and fetal biopsies or placenta specimens seems to be the best method for the diagnosis. Ninety-seven samples from 70 cases of spontaneous abortions after fetal death or hydrops fetalis were examined using PCR. A 270-bp length fragment of the NSI gene was amplified using PCR followed by electrophoresis, by Dot-blot hybridization assay using a biotinylated probe and by Southern-blot hybridization assay using a horseradish peroxidase-labelled probe followed by chemiluminescent assay. The Southern-blot hybridization assay was the longest test but the most sensitive. The parvovirus B19 genome was identified in 10 cases. In two cases, intrauterine blood transfusions led to the cessation of symptoms and to the birth of normal babies.

Abstract
Thirteen laboratories participated in blind tests of a panel of 20 coded cerebrospinal fluid specimens (7 uninfected samples, 3 samples infected with 1 50% tissue culture infective dose [TCID50]/0.1 ml [nonenterovirus strains], and 10 samples infected with 10, 1, or 0.1 TCID50/0.1 ml [three different enterovirus serotypes]) on the Amplicor enterovirus PCR assay (Roche Diagnostic Systems). The panel was also evaluated by in-house PCR (two nested-PCR and three one-step PCR assay) or tissue culture (eight laboratories). The viral load was shown to influence greatly the sensitivity of the assay. The average sensitivity of the Amplicor test ranged from 67 to 98% for viral titers of 1 to 10 TCID50/0.1 ml, respectively; titers of 0.1 TCID50/0.1 ml resulted in a sensitivity of only 16%. The overall specificity of the Amplicor test was 98%. The Amplicor assay compared favorably to the five in-house PCR tests (no significant difference in either sensitivity or specificity) and was much more sensitive than tissue culture (P < 0.001), even for high viral loads. It was easy to perform, rapid (about 6 h), well-standardized, and appeared to be suitable for the diagnosis of enterovirus meningitis on a routine basis in laboratories trained in molecular biology techniques.

Abstract
The pathogenesis of CVB3-induced chronic myocarditis remains unknown. Activated monocytes and macrophages may maintain ongoing inflammation during a persistent CVB3 infection and possibly represent the major mechanism leading to chronic myocarditis. We decided to study the activation status of cells by studying TNF alpha secretion in vitro using whole blood culture in CVB3-induced murine chronic myocarditis. Seven DBA/2 +/+ mice and 18 NMRI nu/nu mice were inoculated intraperitoneally with 5x10(5) pfu of CVB3, and mice were mock-infected. Thirty-one days post-infection, all mice were sacrificed, blood samples were obtained from the heart, and the heart was removed. Enteroviral genomic detection by RT-PCR, virus isolation and histological analysis of heart samples were performed. Heparinized whole blood (25 microliters) was cultured for 4 hr and 24 hr in sterile 96 well-plate containing 225 microliters RPMI in the presence or the absence of activators (LPS + PHA). The TNF alpha levels in the whole blood from mock-infected DBA/2 (n = 4) and NMRI nu/nu mice (n = 5) were not different. A moderate increase of TNF alpha was observed in three out of five DBA/2 mice with negative CVB3 that had no histological abnormalities in myocardium. An increased level of TNF alpha was found in the sole DBA/2 mouse with positive CVB3 detection and chronic myocarditis. An increased level of TNF alpha was found in one out of nine NMRI nu/nu mice with positive CVB3 detection and chronic myocarditis and in one out of seven mice with positive CVB3 detection exempt of lesions in myocardium. In other infected mice, the level of TNF alpha was normal. Enteroviral genome was not detected in the blood from infected mice at 31 days post-infection. The increased TNF alpha level in some mice may be designed for a beneficial inflammatory and immune response, however, an exaggerated release may be associated with an adverse effect. The normal TNF alpha level in whole blood cultures from mice with chronic myocarditis does not exclude enhanced cytokine production at infected loci such as myocardial tissue. This is the first report to use whole blood cultures to study the production of cytokines in virus-induced disease in a small animal model.

Abstract
Enteroviruses are suspected to be etiologic agents in myocarditis and cardiomyopathy. The prevalence of enteroviral (EV) heart infection in patients with chronic cardiomyopathy was determined through detection of specific EV genomic sequences using reverse transcription and polymerase chain reaction (RT-PCR) followed by slot blotting. Endomyocardial biopsies from the explanted hearts of 19 patients with dilated cardiomyopathy (DCM) and 14 patients with chronic coronary disease (CCD) were examined. EV genome was detected in 11 of 19 patients with DCM and in 8 of 14 patients with CCD. Ventricular biopsies from the control group, which included 35 healthy heart patients and 33 patients with myocardial infarction, were negative by EV RT-PCR. The percentage of patients showing presence of EV-RNA was almost similar in the DCM (57.9%) and CCD (57.1%) groups. The present study demonstrates that enterovirus RNA sequences persist in the myocardium in a significant proportion of patients suffering from end-stage ischaemic and dilated cardiac diseases and supports the hypothesis of a possible direct link between EV infection and the pathogenesis of chronic heart disease.

Abstract
Enteroviral RNA (EV-RNA) was detected in endomyocardial tissue by means of retrotranscription and polymerase chain reaction (RT-PCR) followed by slot-blot hybridization. The myocardial biopsy specimens studied were taken at the time of heart transplantation from 15 patients with dilated cardiomyopathy (DCM) and from 10 patients with ischemic cardiomyopathy (ICM). Specimens from 18 (72%) of the 25 patients were positive for EV-RNA, whereas no control specimens (myocardial specimens from 29 healthy organ donors and atrial specimens from 15 patients with acute myocardial infarction treated by anatomic bypass) yielded evidence of EV-RNA. The rates of EV-RNA detection for the two groups requiring heart transplantation did not differ significantly (66.7% vs. 80.0%; chi 2 test). Our findings support a link between enteroviral infection in both DCM and ICM and suggest a pathogenic role for the enteroviruses.
