Abstract
The aim of this pilot study was to analyze the Hepatitis C Virus (HCV) genotypes circulating in Senegal among Drug User (DUs), using Dried Blood Spots (DBS) as RNA source for molecular assays. Heroin and/or cocaine users (n = 506) were recruited in Dakar from April to July 2011, using a Respondent Driven Sampling (RDS) method. DBS preparation consisted of five drops of whole blood from finger applied to a Whatman paper card. HCV infection was screened by the detection of anti-HCV antibodies, using a rapid immune-chromatographic test. HCV RNA was quantified on anti-HCV positive DBS, using the Abbott RealTime HCV® Genotyping was performed on DBS with detectable viral load with Versant® HCV Genotype 2.0 Assay (LiPA) and Abbott RealTime HCV Genotype II assay®. Among the 506 participants, 120 were tested as positive for anti-HCV antibodies and their samples were analyzed for HCV RNA viral load and genotype. Out of the 120 DBS tested, HCV RNA was detected on 25 (20.8%). The median viral load was 15,058 IU/ml (ranging from 710 to 766,740 IU/ml). All positive DBS were suitable for the genotyping assay, that showed a predominance of genotype 1 (21/25) including 16 genotypes 1a and 5 genotypes 1b. HCV genotype 1 prevails in a DU population in Dakar. DBS could be useful for HCV RNA genotyping, but optimal storage conditions should required avoiding RNA impairment. Acknowledging this limitation, DBS could be a great interest for detecting and genotyping HCV viremic patients. J. Med. Virol. 89:484-488, 2017. © 2015 Wiley Periodicals, Inc.

Abstract
BACKGROUND Hemorrhagic cystitis (HC) is a common complication after hematopoietic allogeneic stem cell transplantation (HSCT) associated with intensity of the conditioning regimen, cyclophosphamide (Cy) therapy, and BK polyomavirus (BKPyV) infection. METHODS We analyzed 33 consecutive haploidentical (haplo) HSCT recipients transplanted for hematologic diseases. Eleven patients had a previous transplant. Median follow-up was 11 months. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine + mycophenolate mofetil and post-HSCT Cy. RESULTS Thirty-two of 33 patients achieved neutrophil recovery. Cumulative incidence (CI) of platelet recovery was 65%. CI grade II-IV acute GVHD was 44%. Twenty patients developed HC in a median time of 38 days. CI of HC at day 180 was 62%. BKPyV was positive in blood and urine of 91% of patients at HC onset. HC resolved in 18/20 patients. Factors associated with HC were previous transplant (P = 0.01) and occurrence of cytomegalovirus reactivation before HC (P = 0.05). Grade II-IV acute GVHD was not associated with HC (P = 0.62). CI of day 180 viral infections was 73%. Two-year overall survival (OS) was 50%; HC did not impact OS (P = 0.29). CONCLUSION The incidence of HC after haplo with post-HSCT Cy is high and is associated with morbidity, especially in high-risk patients such as those with a previous transplant history and with impaired immune reconstitution.

Abstract
BACKGROUND Consequences of latent cytomegalovirus (CMV) infection reactivation on inflammatory bowel disease (IBD) flare, as a flare-worsening factor or simple bystander, are debated. Impact of anti-viral treatment on IBD course is poorly known. AIM To assess the impact of CMV reactivation on patients hospitalised for IBD flare and the effect of anti-viral treatment on IBD flare in patients with CMV reactivation. METHODS First, a population of UC patients from Saint-Antoine hospital, in flare with positive blood CMV PCR without anti-viral treatment (n = 26), were compared to matched patients with negative blood CMV PCR in a case-control study. Secondly, a total of 110 hospitalisations between October 2003 and May 2012 for IBD flare-up with CMV reactivation (80 diagnosed on blood PCR, 33 on tissue PCR) were identified in three French referral centres. Evolution following CMV reactivation diagnosis was compared between patients receiving anti-viral treatment and those who did not. RESULTS In the case-control study, no differences were observed between the two groups regarding length of hospital stay and colectomy rate. Comparing treated and untreated patients, no differences were observed at inclusion regarding age, gender, IBD type, immunosuppressant, CRP and haemoglobin level. No differences were observed regarding CRP level decrease at 10 days and colectomy rate at 3 months. Anti-viral treatment was associated with lower serum albumin level at inclusion and longer hospitalisation. CONCLUSIONS CMV reactivation does not appear to alter the course of IBD flare. CMV treatment does not seem to impact the course of IBD. These results should be confirmed prospectively.

Abstract
Virological interactions of hepatitis B (HBV), hepatitis C (HCV) and hepatitis D (HDV) viruses in HIV-infected patients have been poorly characterized especially under treatment influences. Undetection rates of hepatitis viruses were longitudinally analyzed in a 3-year cohort of 308 HIV-HBV co-infected patients and compared using Generalized Estimating Equation models adjusted for age, HIV-RNA, CD4 cell-count and antiviral treatment. Chronic hepatitis co-infection in HIV-infected patients (age years, SD) was: 265 HBV (40.7, 8.2); 19 HBV-HCV (39.7, 4.1); 12 HBV-HDV (35.2, 9.9); 12 HBV-HCV-HDV (39.2, 5.2). At inclusion, treatment with lamivudine/tenofovir was not significantly different between co-infection groups. HBV suppression was significantly associated with HDV (aOR = 3.85, 95%CI 1.13-13.10, P = 0.03) and HCV tri-infection (aOR = 2.65, 95%CI 1.03-6.81, P = 0.04), but marginally associated with HIV-HBV-HCV-HDV (aOR = 2.32, 95%CI 0.94-5.74, P = 0.07). In quad-infection, lower HDV-undetectability (vs HIV-HBV-HDV, P = 0.2) and higher HCV-undetectability (vs HIV-HBV-HCV, P = 0.1) were demonstrated. The degree of HBV suppression varied between visits and co-infection groups [range of aOR during follow-up (vs HIV-HBV co-infection): HIV-HBV-HCV = 2.23-5.67, HIV-HBV-HDV = 1.53-15.17]. In treated co-infected patients, HDV expressed continuous suppression over HCV- and HBV-replications. Peaks and rebounds from undetectable hepatitis B, C and/or D viremia warrant closer follow-up in this patient population. HDV-replication was uncontrolled even with antiviral treatment.

Abstract
Fulminant hepatitis of unknown origin remain a significant cause of mortality, for which liver transplantation is often considered as the only therapeutic option. In retrospective studies, human herpesvirus 6 (HHV-6) infections have been associated with such diseases, but the diagnosis of HHV-6 infection of the liver is rarely established during the acute phase of liver failure. Using real-time polymerase chain reaction (PCR), we diagnosed two cases of severe acute liver failure (ALF) related to HHV-6 occurring in immunocompetent young adults. Both cases had a favourable outcome, one after valganciclovir therapy, one after liver transplantation associated with ganciclovir. Viral origin was evidenced in each case by the detection of high amounts of HHV-6 DNA in liver tissue by the PCR assay. The decrease of intrahepatic viral load after therapeutic intervention was also monitored by quantitative PCR and paralleled in the two cases the clinical improvement. Diagnosis of HHV-6 infection must be systematically evoked in case of unexplained ALF, since it might lead to specific therapeutic interventions, in addition of liver transplantation.

Abstract
OBJECTIVE To study the natural history and the current risk factors for cytomegalovirus (CMV) disease in the context of highly active antiretroviral therapy (HAART). SETTING Prospective multicentre cohort in 15 university hospitals in France. METHODS A group of 198 patients with CD4 cell count < 100 x 10(6) cells/l (or < 200 x 10(6) cells/l under HAART for at least 2 months), no previous CMV disease and CMV-positive serology were followed every 4 months clinically and for virological testing including HIV RNA and CMV blood markers (culture, pp65 antigenaemia, plasma CMV DNA and CMV late mRNA by the polymerase chain reaction). RESULTS At inclusion, median CD4 was 77 x 10(6) cells/l (0-308) and 85% of the patients received protease inhibitors. The percentage of patients receiving HAART reached 99% at 12 months. After a follow-up of 23.6 months, the incidence of CMV disease was 3.2/100 patient-years [95% confidence interval (CI) 1.3-5.0]. In univariate Cox models, all the CMV markers, a CD4 cell count remaining < 75 x 10(6) cells/l and an HIV viral load > 100,000 copies/ml were predictive for CMV disease. The hazard ratios for CMV disease were 11 for blood culture; 14 and 70 for pp65 antigenaemia of > or = 1 and > or = 100 nuclei/200,000 cells, respectively; 35 for plasma CMV DNA; 6 for CMV mRNA; 29 for CD4 < 75 x 10(6) cells/l; and 12 for HIV RNA > 100,000 copies/ml. In a stepwise multivariate analysis, only three covariates were independently associated with the occurrence of a disease: plasma CMV DNA, pp65 antigenaemia > or = 100 nuclei/200,000 cells and a CD4 count < 75 x 10(6) cells/l. CONCLUSION CMV blood markers and CD4 count < 75 x 10(6) cells/l remain risk factors for CMV disease in patients receiving HAART. Analysis of plasma CMV DNA by the polymerase chain reaction is a reproducible and standardized tool that could be used as a decision marker for initiating CMV pre-emptive therapy.

Abstract
OBJECTIVE To evaluate the efficacy and safety of the foscarnet-ganciclovir combination in induction therapy (IT) and maintenance therapy (MT) for cytomegalovirus (CMV) central neurological disorders in HIV-infected patients. DESIGN An open pilot non-comparative multicentre study. METHODS Thirty-one patients with acute CMV encephalitis (CMVe) (n = 17) or CMV myelitis (CMVm) (n = 14) during the era before highly active antiretroviral therapy (HAART) received intravenous IT with foscarnet 90 mg/kg plus ganciclovir 5 mg/kg twice a day followed by MT. The primary endpoint was clinical efficacy, assessed at the end of the induction phase. RESULTS The foscarnet-ganciclovir combination in IT resulted in a 74% (23 out of 31 patients) clinical improvement or stabilization. Eight patients did not respond clinically. Side-effects leading to drug discontinuation occurred in 10 patients during IT. Among the 23 patients who qualified for the maintenance phase, CMV disease progressed in 10, with a median time to the first relapse of 126 days (range 64-264 days). Overall, the median survival time was 3 months [95% confidence interval (CI), 2-4 months]. CONCLUSION The combination of foscarnet and ganciclovir can safely be used for CMV central nervous system (CNS) infection, with an improvement or stabilization in 74% of patients. Life-long MT with this combination is recommended as long as the immune system is profoundly impaired.

Abstract
Herpes simplex virus hepatitis (HSV hepatitis) is an uncommon and severe complication of HSV type 1 and HSV type 2 infection. HSV hepatitis affects mostly immunocompromised patients. We report the case of a young man without any previous known immunodeficiency who developed fatal HSV hepatitis in the first 8 days of oral corticotherapy given for ulcerative colitis. A prompt diagnosis was possible because HSV was recovered from peripheral blood leukocytes.

Abstract
Neurological complications are particularly common during HIV infection. Among various opportunistic diseases, cytomegalovirus (CMV) is one of the most frequent causes of central and peripheral neurological manifestations. Previously, there have been several reports of cranial nerve infection by CMV, but to our knowledge, no cases of auditory nerve involvement have been described. We report two cases in which CMV infection was revealed by involvement of the VIIIth cranial nerves. Cytomegalovirus (CMV) infection is frequent in severely immunodeficient patients infected by human immunodeficiency virus (HIV). The main targets of CMV are the retina, gastrointestinal tract and central nervous system. We describe two cases in which neurologic CMV infection was revealed by hearing loss.

Abstract
Protein tyrosine kinase (PTK) phosphorylation is involved in cellular proliferation and differentiation processes that are key factors for human immunodeficiency virus type 1 (HIV-1) regulation in infected monocytic cells. Short-term exposure of the chronically infected promyelocytic OM10 cell line with the PTK inhibitor genistein induced a dose-dependent increase in p24 antigen production in culture supernatants. This induction persisted in the presence of the reverse transcriptase inhibitor, zidovudine, and was associated with an increased transcription of HIV-1 multiply spliced and unspliced RNAs, suggesting a transcriptional mechanism targeting the integrated provirus. Genistein induced cell differentiation, apoptosis, and a G2 arrest in the OM10 cells. Cell differentiation and apoptosis were not directly involved in the observed increase in HIV-1 replication that was closely linked to genistein-induced G2 arrest. Alleviation of the G2 arrest by pentoxyfylline resulted in a concomitant reduction of HIV-1 to baseline replication. Additionally, by flow cytometry, a significant increase in the number of p24 antigen-expressing cells was observed in cells arrested in G2 compared to those located in G1 or S. Tyrosine kinase inhibition was found not to be essential for enhanced viral replication, which seemed to be related to two other properties of genistein, inhibition of topoisomerase II activity and inhibition of phosphotidylinositol turnover. These findings are consistent with the recent observation that HIV-1 Vpr induces viral replication through preventing proliferation of cells by arresting them in G2 of the cell cycle and strongly suggest that manipulation of the cell cycle plays an important role in HIV-1 pathogenesis.

Abstract
OBJECTIVE To investigate the role of the Fas-Fas ligand (FasL) interaction in HIV-1-induced apoptosis of primary CD4+ T lymphocytes. DESIGN Activated CD4+ T lymphocytes are the main target of HIV, and T-cell activation leads to the expression of Fas-FasL and enhances HIV-mediated apoptosis. Phytohemagglutinin-activated primary CD4+ T cells were infected with HIV; the process of cell death was examined, and whether the dying and dead cells were the productively infected cells. The modulation of Fas and FasL expression and its role in HIV-induced cell death was also investigated. METHODS The number of viable and dead cells was determined by trypan blue exclusion. Apoptosis was quantified using an enzyme-linked immunosorbent assay measuring the release of cytoplasmic histone-associated DNA fragments. The percentage of HIV-infected cells was determined by FACS analysis, and viral production was assessed by a p24 core antigen assay. The following three markers, HIV-gp-120, annexin-V and 7-AAD, were used to monitor the apoptotic process in HIV-negative and positive cells. Fas and FasL expression was analyzed at the RNA level by reverse transcription polymerase chain reaction and at the protein level by flow cytometry. The contribution of Fas-FasL interactions to apoptosis was examined by blocking experiments using the antagonist ZB4 anti-Fas antibody. RESULTS HIV-induced apoptosis in activated purified CD4+ T lymphocytes required infectious virus and was dose-dependent. Apoptosis in HIV-infected cultures was mostly confined to productively infected cells. The expression of Fas and FasL was not significantly modulated by infection and blocking Fas-FasL interactions did not reduce the extent of apoptosis. CONCLUSIONS HIV-induced apoptosis of activated CD4+ T cells in vitro is confined to productively infected cells and is not mediated by a Fas-FasL interaction.

Abstract
Preemptive therapy is a promising strategy for the prevention of serious cytomegalovirus (CMV) disease after bone marrow (BM) transplantation but requires relevant diagnostic tests. We compared the clinical value of a reverse transcription (RT)-PCR method, which detected a late viral mRNA in peripheral blood leukocytes (PBL), with a PCR method that detected the viral DNA in PBL and with viral culture from leukocytes and urine for the diagnosis of symptomatic CMV infection after BM transplantation. Forty-five consecutive BM recipients were prospectively tested at weekly intervals by the four methods. CMV infection, demonstrated either by the culture of CMV or by repeated detection of viral DNA, was observed in 28 patients, but only 14 developed CMV-related clinical symptoms. The clinical sensitivity and specificity of each technique for detection of symptomatic infection were, respectively, 36 and 74% for urine culture, 43 and 84% for leukocyte culture, 100 and 65% for PCR, and 71 and 94% for RT-PCR. Although PCR detection of DNA in PBL was the earliest and most sensitive technique for the diagnosis of CMV infection, RT-PCR was more predictive of the onset of CMV-related clinical symptoms. These data suggest that both molecular methods should be used for identifying BM recipients at highest risk of CMV disease.

Abstract
We successfully infected fluorescence-activated cell-sorted CD34+ cells from normal cord blood by the human cytomegalovirus (HCMV) laboratory strain Towne. An inhibitory effect of HCMV on clonogenic myeloid progenitors was observed in primary methylcellulose cultures. After an initial 7-day liquid culture of CD34(+)-infected cells, this inhibition was further amplified in secondary methylcellulose cultures, then involving both the myeloid and erythroid lineages. Under these conditions, viral DNA was detected both in erythroid and myeloid colonies using the polymerase chain reaction (PCR), but reverse transcription PCR (RT-PCR) failed to detect viral RNA. In contrast, when CD34(+)-infected cells were maintained in liquid suspension, both immediate, early, and late transcripts were detected as soon as day 3. In addition, viral production was demonstrated in the culture supernatants, thus confirming that a complete viral cycle occurred under liquid conditions. Furthermore, by resorting cells into CD34+ and CD34- fractions, we showed by RT-PCR that viral replication took place in cells still expressing CD34 antigen, whereas no RNA was found in more differentiated cells that had subsequently lost their CD34 antigen. These findings suggest that HCMV replication can occur at the early steps of progenitor differentiation and may be involved in the viral-induced myelosuppression.

Abstract
OBJECTIVES Neurologic infections caused by cytomegalovirus are common in patients with acquired immunodeficiency syndrome (AIDS). The prognosis is particularly severe when the infection is localized in the conus medullaris and/or the cauda equina. METHODS Among the 861 patients with AIDS treated in our unit from 1991 to 1993, 7 cases involving cytomegalovirus infection of the conus medullaris and/or the cauda equina were studied retrospectively. RESULTS OF THE CASE REPORTS: Clinical manifestations were nearly always the same: low back pain, motor deficiency in the lower limbs progressing to flaccid paraplegia and sphincter failure. The cerebrospinal fluid contained a high cell count with unaltered polynuclears and increased protein levels. In 6/7 patients virus cultures and search for the viral genome in the cerebrospinal fluid were positive. The clinical course was favourable in 6 patients after 3 weeks treatment with ganciclovir and/or foscarnet. Virology tests became negative in three-fourths of the patients. Nevertheless, relapse occurred after 4.2 weeks despite long-term therapy. CONCLUSION The severe clinical course of this disease and the gravity of constantly fatal relapse requires highly adapted treatment and overall health care.

Abstract
OBJECTIVE To study the predictive value of clinical criteria and polymerase chain reaction (PCR) assay of cerebrospinal fluid (CSF) for the diagnosis of cytomegalovirus (CMV)-related neurological disorders during AIDS. SETTING Four infectious diseases departments in two tertiary referral teaching hospitals in Paris, France. DESIGN AND PARTICIPANTS One-year prospective study involving 164 consecutive immunosuppressed HIV-seropositive patients undergoing lumbar puncture (LP). METHODS A tentative diagnostic classification, based on strict operational criteria and PCR assay of CSF, was performed at the time of LP. At the end of the study, tentative diagnoses and PCR results were blindly and independently compared with the firm diagnoses, based on central nervous system histology, clinical outcome and/or viral culture of CSF. RESULTS The tentative diagnosis showed CMV-related neurological disease in 38 patients, and CMV DNA was detected in 42. Among the 88 patients for whom a firm diagnosis was possible, 26 had a diagnosis of CMV-related neurological disease. The concordance between the tentative and firm diagnoses was 61%, with a kappa index of 0.40. In contrast, the sensitivity and specificity of PCR were respectively 92 and 94%, with positive and negative predictive values of 86 and 97%. The presence of CMV DNA in CSF was associated with an increased risk of death (P < 0.0001). CONCLUSIONS Unlike clinical criteria, PCR detection of viral DNA in CSF can be used reliably for antemortem diagnosis of CMV-related neurological disease, a frequent complication of AIDS in this study. This rapid method should make a major impact on the management of these patients.

Abstract
A severe multifocal neuropathy caused by cytomegalovirus (CMV-MN) can occur in the late stage of human immunodeficiency virus (HIV) infection. In a retrospective study, we identified 15 consecutive HIV-positive patients with a diagnosis of CMV-MN based on (1) markedly asymmetric neuropathy, (2) fewer than 100 CD4+ cells per mm3, (3) exclusion of other causes of neuropathy, and (4) characteristic CMV cytopathic changes on neuromuscular biopsy (2 patients), positive CSF culture for CMV (2 patients), or clinical improvement on anti-CMV therapy given for concurrent extraneurologic CMV disease (8 patients) or neuropathy (3 patients). All patients were men and had severe immunosuppression (mean CD4+ cell count, 18 per mm3). The initial symptoms were numbness and painful paresthesias showing a patchy, multifocal distribution. After a mean of 11 weeks (range, 1 to 10 months), the patients developed moderate or severe sensorimotor asymmetric neuropathy. Extraneurologic CMV infection occurred in 10 patients before diagnosis. Electrophysiologic studies showed axonal neuropathy and CMV DNA was present in CSF by the polymerase chain reaction (PCR) technique in 90% of patients tested. Fourteen patients showed a marked improvement 1 to 4 weeks after starting ganciclovir or foscarnet therapy. During follow-up on maintenance therapy (13 patients), the neuropathy relapsed in three patients and probable or confirmed CMV encephalitis occurred in five. Twelve patients died during follow-up, at a mean interval of 9.5 months after their first symptoms. These results extend the clinical spectrum of CMV-MN and show that PCR detection of CMV DNA in CSF may be a useful diagnostic marker.

Abstract
A reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect a human cytomegalovirus (HCMV) late mRNA in peripheral blood leukocytes (PBL) of 102 human immunodeficiency virus-infected individuals. The clinical value of this new technique for the diagnosis of acute HCMV disease was evaluated in comparison with viral culture and direct amplification of viral DNA (PCR). The sensitivity of the RT-PCR was slightly lower than that of the two other methods, but its specificity was 94%, compared to 55 and 32% for culture and PCR, respectively. Transcription of this late mRNA is linked to viral replication, and its detection in PBL confirms that these cells can support a complete viral cycle. The relationship between complete replicative cycles and HCMV disease makes RT-PCR a useful clinical tool.

Abstract
A polymerase chain reaction (PCR)-based method was used to detect cytomegalovirus (CMV) DNA in 82 cerebrospinal fluid (CSF) samples from 67 patients infected by human immunodeficiency virus (HIV). The test was positive for 14 patients, 8 of whom had CMV-related neurologic disease proven by viral culture of CSF or histologic examination. Encephalitis was the most frequent manifestation in patients with positive PCR results, but CMV DNA was also present in some patients with peripheral neuropathy or polyradiculomyelitis. All patients with proven CMV neurologic disease were positive by PCR. In contrast, viral culture was negative for 4 of the 8 patients and pathologic studies were available only for 5. The specificity of the PCR-based assay could not be assessed precisely because of the lack of a reference standard, but the results correlated well with clinical course and results of the other methods. These findings suggest that the PCR-based method may be a useful noninvasive tool for the rapid diagnosis of CMV-related neurologic disease.

Abstract
A rapid and simple application of the polymerase chain reaction is described for the detection of human cytomegalovirus (HCMV) mRNAs in cells infected in-vitro. The method was first used to study the transcription of two HCMV genes, and confirm the link between the transcription of one, encoding for the major capsid protein, and viral replication. The oligonucleotides chosen in this region were specific for HCMV genome and sensitivity experiments showed that a single infected cell in 5 x 10(5) can be detected. Detection of this transcript should be suitable for diagnostic purposes, permitting the distinction between latency and active infection.

Abstract
PURPOSE To determine whether Epstein-Barr virus (EBV) could be involved in the pathogenesis of Sjögren's syndrome (SS). PATIENTS AND METHODS In situ hybridization using the BamH1-W fragment of EBV DNA was performed using labial salivary gland biopsy specimens from 14 patients with SS (eight with primary SS and six with secondary SS) and 39 control subjects. Furthermore, labial salivary gland biopsy specimens from 12 patients with SS (seven with primary SS and five with secondary SS) and 24 control subjects were submitted to the polymerase chain reaction to detect EBV DNA. RESULTS In situ hybridization detected EBV DNA in epithelial cells of labial salivary gland biopsy specimens from four of eight (50%) patients with primary SS, zero of six patients with secondary SS, and three of 39 (8%) control subjects. The difference between patients with primary SS and control subjects was statistically significant (p less than 0.02). The polymerase chain reaction detected EBV DNA in six of seven (86%) patients with primary SS, three of five (60%) patients with secondary SS, and seven of 24 (29%) control subjects. The difference between patients with primary SS and control subjects was statistically significant (p less than 0.01). CONCLUSION Both newly developed techniques showed that the presence of EBV DNA was significantly increased in patients with primary SS in comparison with control subjects. In all the positive SS patients who underwent in situ hybridization, epithelial cells of the labial salivary gland were the target of EBV infection. Our results suggest that this virus may play a role in the pathogenesis of SS. We cannot yet determine whether EBV is directly responsible for the destruction of the gland, or if its presence is a secondary event following gland injury.

Abstract
Using in-situ hybridizaiton, we showed the presence of the Epstein-Barr (EB) virus genome in epidermal cells from a patient with chronic lymphocytic leukemia and unusual cutaneous lesions characterized clinically by a maculopapular eruption and histologically by epidermal cell degeneration and lymphoid cell infiltration. Such histologic changes are similar to those seen in graft-versus-host disease. The EB virus genome was mainly detected in the basal, germinative cells of the abnormal epithelium. Specimens of our patient's healthy skin were negative. The presence of EB virus DNA in skin lesions was confirmed by polymerase chain reaction adapted for analysis of paraffin-embedded tissue. These findings indicate that EB virus can infect the human epidermis and that the viral infection may produce a distinctive cutaneous disease.
