Abstract
INTRODUCTION Letermovir is a cytomegalovirus (CMV) terminase complex inhibitor approved for prophylaxis of CMV infection and disease in adult CMV-seropositive allogeneic hematopoietic cell transplantation (allo-HCT) recipients (R+). We report pharmacokinetics (PK), safety, and efficacy of letermovir in adolescent (12-18 years) allogeneic HCT recipients from an ongoing clinical study. METHODS In this phase 2b, multicenter, open-label study (NCT03940586), 28 adolescents received 480 mg letermovir [240 mg with cyclosporin A (CsA)] once daily orally or intravenously. Blood was collected for intensive (n = 14) plasma concentrations of letermovir. Intensive PK data were used for dose confirmation. Target exposure range 34,400-100,000 h × ng/mL for pediatric median exposures was based on model-predicted phase 3 population PK simulations in adult HCT recipients. RESULTS All participants were CMV-seropositive (body weight 28.7-95.0 kg). Of 12 PK-evaluable participants, 8 receiving 480 mg letermovir without CsA and 4 receiving 240 mg letermovir with CsA achieved exposures comparable to the adult exposure range. Exposure above the target but below the adult clinical program maximum was observed in 1 patient. Safety was consistent with previously described safety in adults. The proportion of participants with clinically significant CMV infection through week 24 post-HCT was comparable (24%) to that in the pivotal phase 3 study in adults (37.5%). CONCLUSIONS Administration of adult letermovir doses in this adolescent cohort resulted in exposures within adult clinical program margins and was associated with safety and efficacy similar to adults. Results support a letermovir dose of 480 mg (240 mg with CsA) in adolescent allo-HCT recipients.

Abstract
INTRODUCTION Pre-emptive therapy for cytomegalovirus (CMV) reactivation has been used in allogeneic hematopoietic stem cell transplantation (allo-HSCT). It is unclear if this strategy has poorer clinical outcomes in CMV-endemic areas and if more aggressive prophylaxis is required. METHODS We retrospectively analyzed the patterns and survival after CMV reactivation in patients undergoing pre-emptive therapy following allo-HSCT and assessed high-risk patients who could benefit from aggressive CMV prophylaxis in endemic areas. RESULTS Of the 292 patients who underwent allo-HSCT, 70.5% (donor+ or recipient+) were CMV seropositive. CMV reactivation occurred in 139 patients (47.6%), with a median of 31.5 days from day 0 of allo-HSCT. The overall survival of patients with CMV reactivation who received pre-emptive therapy did not differ from those without reactivation. Of the 139 patients with CMV reactivation, 78 (56.1%) underwent ≥2 rounds of pre-emptive therapy. In multivariate analysis, the risk of CMV reactivation was higher in patients with multiple myeloma, with CMV seropositivity of the recipient and donor, administered with a higher dose of anti-thymocyte globulin (ATG), and with acute graft-versus-host disease (aGVHD) ≥ grade 2. CONCLUSION Although half of the patients with allo-HSCT were administered with pre-emptive therapy for CMV, CMV reactivation did not affect their survival, indicating the advantages of pre-emptive therapy, even in CMV-endemic areas. The cost-effectiveness of more aggressive CMV prophylaxis should be re-evaluated in patients at a high risk for CMV reactivation.

Abstract
Graft failure is a group of complications after allogeneic hematopoietic stem cell transplantation, which occurs according to different data up to 30%. The group of complications includes primary and secondary graft failure, primary, secondary and transient poor graft function and graft rejection. Diagnostic difficulties consist in the lack of unified diagnostic criteria accepted in the transplantation community and in the dual interpretation of these complications according to the foreign literature. The purpose of this literature review was to identify the most common criteria of different types of graft failure and determine the tactics of diagnosis and treatment. In this review we analyzed data from various literature sources, gave definitions of graft failure and poor graft function. We analyzed the literature data on the methods used to treat these conditions.

Abstract
Human cytomegalovirus (HCMV) remains a major public health burden worldwide. The anti-HCMV activity of glucuronomannan oligosaccharides (Gs) and sulphated glucuronomannan oligosaccharides (SGs) was investigated. Among these Gs and SGs, G4S1 and G6S1 (higher sulphated glucuronomannan tetramer and hexamer) showed satisfactory anti-HCMV activity starting at 50 μg/mL and 10 μg/mL, respectively. The results of the morphology, western blotting, qPCR and TCID50 assay showed that they prevented lytic cytopathic changes, inhibited the expression of IE1/2 and UL44, and reduced the UL123 copy number and virus titre significantly. It was interesting to note that degree of sulphation and polymerization was more important for anti-HCMV activity. Moreover, the anti-HCMV activities of G4S1 and G6S1 were stable when stored at 4 °C, -20 °C, and -80 °C for at least three months and mainly occurred in the early stage of HCMV infection through the negative charge of the sulphate groups and the interaction between SGs and the host cells.

Abstract
OBJECTIVES The human cytomegalovirus is a notorious pathogen in the pediatric transplant setting. Although studies on factors in complicity with cytomegalovirus infection abound, the roles of age, sex, allogeneic hematopoietic stem cell transplant modality, and type of underlying disease (malignant vs nonmalignant) with regard to cytomegalovirus infection and viral load in children are seldom explored. Our aim was to examine the significance of these factors on cytomegalovirus infection and viral load in Serbian pediatric recipients of allogeneic hematopoietic stem cell transplant. MATERIALS AND METHODS Thirty-two pediatric recipients of allogeneic hematopoietic stem cell transplant to treat various malignant and nonmalignant disorders were prospectively monitored for cytomegalovirus infection. The real-time quantitative polymerase chain reaction was used for pathogen detection and quantitation. Demographic and virologic parameters were statistically analyzed with SPSS statistics software (version 20). RESULTS Cytomegalovirus DNA was detected in 23 patients (71.9%). Infection occurred significantly more often (P = .015) in patients with haploidentical donors. The opposite was noted for matched sibling grafts (P = .006). Viral load was higher in female patients (P = .041) and children with malignant diseases (P = .019).There was no significant relationship between viral infection or load and medical complications. CONCLUSIONS Transplant recipients presented with a high incidence of cytomegalovirus viremia. The modality of allogeneic hematopoietic stem cell transplant was associated with the frequency of cytomegalovirus infection. Age, sex, type of underlying disease, and medically relevant events were not conducive to occurrences of viremia. Notably, we observed substantial viral loads in female patients and patients with neoplastic diseases. Studies comprising larger populations are needed to better understand these results.

Abstract
Human cytomegalovirus (HCMV) is the most frequent cause of opportunistic viral infection following transplantation. Viral factors of potential clinical importance include the selection of mutants resistant to antiviral drugs and the occurrence of infections involving multiple HCMV strains. These factors are typically addressed by analyzing relevant HCMV genes by PCR and Sanger sequencing, which involves independent assays of limited sensitivity. To assess the dynamics of viral populations with high sensitivity, we applied high-throughput sequencing coupled with HCMV-adapted target enrichment to samples collected longitudinally from 11 transplant recipients (solid organ, n = 9, and allogeneic hematopoietic stem cell, n = 2). Only the latter presented multiple-strain infections. Four cases presented resistance mutations (n = 6), two (A594V and L595S) at high (100%) and four (V715M, V781I, A809V, and T838A) at low (<25%) frequency. One allogeneic hematopoietic stem cell transplant recipient presented up to four resistance mutations, each at low frequency. The use of high-throughput sequencing to monitor mutations and strain composition in people at risk of HCMV disease is of potential value in helping clinicians implement the most appropriate therapy.

[PMID: 32524342 DOI: 10.1007/s12275-020-9528-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 04/20/2020] [Accepted: 05/06/2020] [Indexed: 12/31/2022]
Abstract
Human cytomegalovirus (hCMV) is a ubiquitous herpesvirus, which results in the establishment of a latent infection that persists throughout the life of the host and can be reactivated when the immunity is low. Currently, there is no vaccine for hCMV infection, and the licensed antiviral drugs mainly target the viral enzymes and have obvious adverse reactions. Thus, it is important to search for compounds with anti-hCMV properties. The present study aimed to investigate the suppressive effects of piceatannol on hCMV Towne strain infection and the putative underlying mechanisms using human diploid fibroblast WI-38 cells. Piceatannol supplementation prevented the lytic changes induced by hCMV infection in WI-38 cells. Furthermore, piceatannol suppressed the expression of hCMV immediate-early (IE) and early (E) proteins as well as the replication of hCMV DNA in a dose-dependent manner. Moreover, hCMV-induced cellular senescence was suppressed by piceatannol, as shown by a decline in the senescence-associated β-galactosidase (SA-β-Gal) activity and decreased production of intracellular reactive oxygen species (ROS). p16INK4a, a major senescence-associated molecule, was dramatically elevated by current hCMV infection that was attenuated by pre-incubation with piceatannol in a dose-dependent manner. These results demonstrated that piceatannol suppressed the hCMV infection via inhibition of the activation of p16INK4a and cellular senescence induced by hCMV. Together, these findings indicate piceatannol as a novel and potent anti-hCMV agent with the potential to be developed as an effective treatment for chronic hCMV infection.

Abstract
Graft-versus-host disease (GVHD) and cytomegalovirus (CMV)-related complications are leading causes of mortality after unrelated-donor hematopoietic cell transplantation (UD-HCT). The non-conventional MHC class I gene MICB, alike MICA, encodes a stress-induced polymorphic NKG2D ligand. However, unlike MICA, MICB interacts with the CMV-encoded UL16, which sequestrates MICB intracellularly, leading to immune evasion. Here, we retrospectively analyzed the impact of mismatches in MICB amino acid position 98 (MICB98), a key polymorphic residue involved in UL16 binding, in 943 UD-HCT pairs who were allele-matched at HLA-A, -B, -C, -DRB1, -DQB1 and MICA loci. HLA-DP typing was further available. MICB98 mismatches were significantly associated with an increased incidence of acute (grade II-IV: HR, 1.20; 95% CI, 1.15 to 1.24; P < 0.001; grade III-IV: HR, 2.28; 95% CI, 1.56 to 3.34; P < 0.001) and chronic GVHD (HR, 1.21; 95% CI, 1.10 to 1.33; P < 0.001). MICB98 matching significantly reduced the effect of CMV status on overall mortality from a hazard ratio of 1.77 to 1.16. MICB98 mismatches showed a GVHD-independent association with a higher incidence of CMV infection/reactivation (HR, 1.84; 95% CI, 1.34 to 2.51; P < 0.001). Hence selecting a MICB98-matched donor significantly reduces the GVHD incidence and lowers the impact of CMV status on overall survival.

Abstract
CONTEXT - Graft-versus-host disease of the gastrointestinal tract is a common complication of hematopoietic stem cell transplant associated with significant morbidity and mortality. Accurate diagnosis can be difficult and is a truly clinicopathologic endeavor. OBJECTIVES - To assess the diagnostic sensitivity of gastrointestinal graft-versus-host disease using the 2015 National Institutes of Health (NIH) histology consensus guidelines and to analyze histologic findings that support the guidelines. DESIGN - Patients with allogeneic hematopoietic stem cell transplants were identified via a retrospective search of our electronic medical records from January 1, 2005, to January 1, 2011. Endoscopies with available histology were reviewed by 2 pathologists using the 2015 NIH guidelines. The clinical diagnosis was used as the gold standard. A nontransplant set of endoscopic biopsies was used as a control. RESULTS - Of the 250 total endoscopies, 217 (87%) had a clinical diagnosis of gastrointestinal graft-versus-host disease. Use of the NIH consensus guidelines showed a sensitivity of 86% and a specificity of 65%. Thirty-seven of 58 (64%) cases with an initial false-negative histopathologic diagnosis were diagnosed as graft-versus-host disease on our review. CONCLUSIONS - Use of the NIH histology consensus guidelines results in a high sensitivity and specificity, thereby decreasing false-negatives. Additionally, use of the NIH guidelines aids in creating uniformity and diagnostic clarity. Correlation with clinical and laboratory findings is critical in evaluating the differential diagnosis and to avoid false-positives. As expected, increased apoptosis with decreased inflammation was associated with a pathologic diagnosis of graft-versus-host disease and supports the NIH guidelines.

Abstract
CONTEXT - Transplant-associated thrombotic microangiopathy is a serious complication of hematopoietic stem cell transplant that may progress to multi-organ dysfunction. Transplant-associated thrombotic microangiopathy may involve the intestinal vasculature (intestinal transplant-associated thrombotic microangiopathy [iTMA]), causing patients to experience debilitating symptoms of ischemic colitis, including disproportionately severe abdominal pain and gastrointestinal bleeding, requiring heavy narcotic use and frequent transfusion support. Pathophysiology remains poorly investigated but may include endothelial damage mediated by inflammatory markers and the complement system. Endoscopy of hematopoietic stem cell transplant patients often produces biopsy samples, in which mucosal lamina propria capillaries are sufficient for an evaluation of iTMA features. OBJECTIVE - To provide a detailed review of histologic features of iTMA. DATA SOURCES - We conducted a systematic review of studies assessing histologic features of iTMA. Studies were identified by PubMed search and included a cohort study performed by our group. CONCLUSIONS - The histologic hallmark of iTMA is endothelial cell injury that leads to hemorrhage and thrombosis of the capillaries. Histologic features include endothelial cell swelling, endothelial cell separation, perivascular mucosal hemorrhage, intraluminal schistocytes, intraluminal fibrin, intraluminal microthrombi, loss of glands, and total denudation of mucosa. Identification of features consistent with iTMA has immediate implications for clinical management that could potentially improve outcome and survival.

Abstract
Sepedonium sp. is a saprophytic fungus that inhabits soil and plant material. Few cases of infection with this fungus have been reported. We describe a case of a child who received haploidentical stem cell transplantation. The patient developed Sepedonium sp. infection after graft failure accompanied by cytomegalovirus infection. This was associated with two genotypes corresponding to a gB1 and gB3 mixture, which suggested involvement of two strains. Throughout the clinical course, immunosuppression and subsequent development of the fungal infection was observed. Our findings add to the available evidence regarding the potential for acquisition of fungal infection from the environment in patients at high risk because of immunosuppression. To the best of our knowledge, this is the first case of Sepedonium sp. infection following graft failure accompanied by previous cytomegalovirus infection in a patient with hematopoietic stem cell transplantation.

Abstract
Hematopoietic stem cell transplantation (HSCT) associated immunocompromised state carries high risk of infectious complications. Mannose-binding lectin (MBL) is an acute phase protein involved in innate immune response. Serum MBL level is genetically determined and quite stable. According to literature, significant association was shown between low MBL concentrations and serious infections. The association between serum MBL level and frequency and severity of infections was studied in 186 patients following autologous HSCT. Double-monoclonal antibody sandwich enzyme-linked immunosorbent assay was used to determine MBL antigen level in sera. MBL levels were measured around 100 days following transplantation, in a period without active infection. Twenty-one patients (11%) were MBL deficient. The median time of first infection and number of infections during the first year post-transplantation were not significantly different between patients with MBL deficiency and those without MBL deficiency. The occurrence and number of infections after HSCT correlated with the MBL/C-reactive protein ratio. The number of severe infections was not higher among those with MBL deficiency. The occurrence of infections after the pre-engraftment period during the first year post-transplantation was significantly different in patient groups separated by MBL cut-off level. The MBL/C-reactive protein ratio might be a useful marker of infectious complications. MBL measurement may be helpful in antibiotic treatment. In case of MBL deficiency, earlier and more intensive treatment may be indicated.

Abstract
Cytomegalovirus (CMV) is a well-established cause of morbidity and mortality in pediatric recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT). CD8⁺ T-cells are important for controlling CMV infection. We conducted a prospective pilot study to investigate the clinical utility of measuring the CMV-specific T-cell immune response using the QuantiFERON-CMV assay (QF-CMV) in pediatric allo-HSCT recipients. Overall, 16 of 25 (64%) patients developed CMV infection. QF-CMV was evaluated in these 16 patients during the early and late phases of the first CMV infection post allo-HSCT. Whereas the initial QF-CMV results during the early phase of CMV infection did not correlate with the course of the corresponding infection, the QF-CMV results post resolution of the first CMV infection correlated with the recurrence of CMV infection until 12 months post allo-HSCT; no recurrent infections occurred in the four QF-CMV-positive patients, while recurrent infections manifested in five of eight QF-CMV-negative (62.5%) and all three QF-CMV-indeterminate patients (P=0.019). In spite of the small number of patients examined, this study supports the potential application of monitoring CMV-specific T-cell immunity using the QF-CMV assay to predict the recurrence of CMV infection in pediatric allo-HSCT recipients.

Abstract
INTRODUCTION Cytomegalovirus (CMV) is a member of the Herpesviruses family. CMV infection rarely causes serious disease in otherwise healthy individuals, however, infection/reactivation among immunocompromised patients, including those undergoing hematopoietic stem cell transplantation (HSCT), can be critical and is associated with high rates of morbidity and mortality. The detection of CMV in blood using real-time polymerase chain reaction (qPCR) methods is the most sensitive and specific technique providing for a well-determined preemptive treatment cutoff. AIM This study compares the performance of two new CMV qPCR platforms, COBAS(®) Ampliprep/COBAS(®) TaqMan(®) (Roche Molecular Diagnostics) and Artus RotorGene (QIAGEN). METHODS A total of 99 patients referred for CMV testing at AUBMC were tested using the Artus CMV RG PCR kit and the COBAS AmpliPrep/COBAS TaqMan CMV kit as per the manufacturers' recommendations. RESULTS The difference between the two methods was within the allowable error for 97 out of 99 specimens (98%), with a correlation coefficient r = 0.80. CONCLUSION The Artus CMV RG PCR Kit and the COBAS AmpliPrep/COBAS TaqMan CMV kit are both acceptable assays that can be used for the sensitive detection and quantitation of CMV mainly in peripheral blood specimens.

Abstract
The enumeration of antigen-specific T cells is increasingly relevant in clinical and research settings. This information is useful for evaluating immune responses to treatment, monitoring the efficacy of anticancer vaccines, and for detecting self-reactive T cells in autoimmune disorders. Quantifying antigen-specific T cells can be accomplished via IFNγ ELISpot assay, the measurement of intracellular cytokine production by flow cytometry, or by lymphocyte proliferation assays in response to antigen. While robust, these technologies are labor-intensive and can take several days to obtain results. New technology has led to more powerful tools for quickly and accurately measuring antigen-specific T cells by flow cytometry via fluorescently-labeled TCR-specific multimers. In this study, we evaluated the use of an assay based on Dextramer reagents for enumerating cytomegalovirus (CMV) antigen-specific T cells (CASTs). Assay performance characteristics were assessed by establishing Dextramers' sensitivity (median=0.4; range=0.1-1.4 CASTs μl(-1) ), determining their specificity (100%), evaluating assay robustness with different leukocyte sources and assay reproducibility via interlaboratory and interinstrument investigations. Furthermore, the levels of CASTs in 95 peripheral blood samples from 62 unique blood and marrow transplants recipients correlated well between Dextramers and Tetramers (R(2) =0.9042).

Abstract
We report a retrospective analysis of Cytomegalovirus (CMV) infection: incidence, recurrence, resistance, and subsequent disease of 81 children who underwent allogenic hematopoietic stem cell transplantation (HSCT). The recipient and/or donor's CMV serology was positive prior to transplant [recipient (R+) and/or donor (D+)]. CMV was monitored by RT-PCR starting from the first week post transplant. Forty patients showed CMV infection (49, 5%). Of them 10 manifested CMV disease leading to four deaths. In univariate analysis, factors associated with CMV infection were CMV R+ P < .01, CMV R+/D+ pair P < .01, nonbone marrow (BM) stem cell source P < .05, nonirradiation conditioning regimen P < .05, Antithymocyte globulin (ATG) P < .01. Factors associated with CMV resistance were: >1 HLA allele mismatch P < .05, CMV R +/D-pair P < .01, CMV D-P < .01, non-BM P < .05, nongenoidentical transplant P < .01. CMV disease was influenced by >1 HLA allele mismatch (P < .001), non-BM (P < .01). On multivariate analysis, CMV R+/D- (P < .05), corticosteroids ≥2 mg/kg P < .01, ATG P < .01 and non-BM (P < .05) were independent factors for CMV infection. CMV R+ transplant is associated with more CMV infection and resistance to preemptive treatment. Prolonged immune suppression (IS) worsens outcome of CMV infection and should be shortened whenever possible.

Abstract
Cytomegalovirus (CMV) infection is 1 of the leading causes of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (aHSCT), mainly within the first 100 days after transplantation. We aimed to characterize CMV infection in a cohort of 305 patients with different malignancies undergoing aHSCT at the Portuguese Institute of Oncology of Porto between January 2008 and December 2012. In total, 184 patients (60.3%) developed CMV infection, mainly viral reactivations rather than primary infections (96.2% versus 3.8%, respectively). The majority of patients (166 of 184) developed CMV infection ≤100 days after transplantation, with median time to infection of 29 days (range, 0 to 1285) and median duration of infection of 10 days (range, 2 to 372). Multivariate analysis revealed that CMV infection was increased in donor (D)-/recipient (R)+ and D+/R+ (odds ratio [OR], 10.5; 95% confidence interval [CI], 4.35 to 25.4; P < .001) and in patients with mismatched or unrelated donors (OR, 2.54; 95% CI, 1.34 to 4.80; P = .004). Cox regression model showed that the risk of death was significantly increased in patients >38 years old (OR, 1.89; 95% CI, 1.14 to 3.12; P = .0137), who underwent transplantation with peripheral blood (OR, 3.02; 95% CI, 1.33 to 6.86; P = .008), with mismatched or unrelated donor (OR, 2.16; 95% CI, 1.48 to 3.13; P < .001), and who developed CMV infection (OR, 1.76; 95% CI, 1.07 to 2.90; P = .025). Moreover, patients who developed CMV infection had a significantly reduced median post-transplantation survival (16 versus 36 months; P = .002).

Abstract
The present study was conducted to investigate Epstein-Barr virus (EBV) reactivation after hematopoietic cell transplantation (HCT) in Korean children living in an area of a high seroprevalence against EBV and to determine the impact of recipient age on EBV reactivation. Medical records of 248 children and adolescents who had received allogeneic HCT were retrospectively reviewed. The trends of EBV reactivation and post-transplant lymphoproliferative disorders (PTLDs) were evaluated and compared between younger (≤10 years old) and older (11-20 years old) groups. EBV reactivation occurred in 177 cases (71.4 %) and high-level EBV reactivation, defined as a virus DNA titer of 300,000 copies/mL or higher, occurred in 21 cases (8.5 %). PTLD was diagnosed in five cases (2.0 %), and one of these patients died. The EBV reactivation rate was not significantly different between the two age groups; however, high-level reactivation and PTLD were more significantly frequent in the older than in the younger group (P = 0.030 and P = 0.026, respectively). In conclusion, older children and adolescents are more likely to experience high-level EBV reactivation and PTLDs, and higher EBV DNA titers than those previously reported may be a predictor of PTLD in areas with a high seroprevalence against EBV.

Abstract
The respiratory tract is a common site of infection in cancer patients and is associated with substantial moribidity and mortality in this population. Cancer, chemotherapy, and radiation can all cause noninfectious pulmonary infiltrates and respiratory symptoms that can masquerade as a respiratory tract infection. Cancer patients are at a particular risk for infection by a wide variety of different viruses, fungi, and bacteria that can be difficult to treat. Although noninvasive diagnostics have significantly improved recently, patients with severe pneumonia and those not responding to usual therapy should be candidates for aggressive diagnostic testing and tissue sampling. Initial therapy should be carefully chosen and individually tailored to account for the individual patient's underlying risk factors for multi-drug-resistant pathogens, viral pathogens, or fungi. Once diagnostic testing returns, therapy should be altered to appropriately narrow the spectrum of coverage.

Abstract
Antiviral therapy for cytomegalovirus (CMV) plays an important role in the clinical management of solid organ and hematopoietic stem cell transplant recipients. However, CMV antiviral therapy can be complicated by drug resistance associated with mutations in the phosphotransferase UL97 and the DNA polymerase UL54. We have developed an amplicon-based high-throughput sequencing strategy for detecting CMV drug resistance mutations in clinical plasma specimens using a microfluidics PCR platform for multiplexed library preparation and a benchtop next-generation sequencing instrument. Plasmid clones of the UL97 and UL54 genes were used to demonstrate the low overall empirical error rate of the assay (0.189%) and to develop a statistical algorithm for identifying authentic low-abundance variants. The ability of the assay to detect resistance mutations was tested with mixes of wild-type and mutant plasmids, as well as clinical CMV isolates and plasma samples that were known to contain mutations that confer resistance. Finally, 48 clinical plasma specimens with a range of viral loads (394 to 2,191,011 copies/ml plasma) were sequenced using multiplexing of up to 24 specimens per run. This led to the identification of seven resistance mutations, three of which were present in <20% of the sequenced population. Thus, this assay offers more sensitive detection of minor variants and a higher multiplexing capacity than current methods for the genotypic detection of CMV drug resistance mutations.

Abstract
Human cytomegalovirus (HCMV) is a significant cause of morbidity and mortality in organ transplant recipients. The use of granulocyte-colony stimulating factor (G-CSF)-mobilized stem cells from HCMV seropositive donors is suggested to double the risk of late-onset HCMV disease and chronic graft-versus-host disease in recipients when compared to conventional bone marrow transplantation with HCMV seropositive donors, although the etiology of the increased risk is unknown. To understand mechanisms of HCMV transmission in patients receiving G-CSF-mobilized blood products, we generated a NOD-scid IL2Rγ(c)(null)-humanized mouse model in which HCMV establishes latent infection in human hematopoietic cells. In this model, G-CSF induces the reactivation of latent HCMV in monocytes/macrophages that have migrated into organ tissues. In addition to establishing a humanized mouse model for systemic and latent HCMV infection, these results suggest that the use of G-CSF mobilized blood products from seropositive donors pose an elevated risk for HCMV transmission to recipients.

Abstract
This retrospective study reviews the results of our experience with the occurrence of CMV DNAemia in islet cell transplanted cynomolgus monkeys subjected to different immunosuppressive protocols, including induction treatment with thymoglobulin (TMG), with a combination of thymoglobulin and fludarabine (FLUD), with cyclophosphamide, or with daclizumab. CMV DNA in the peripheral blood (CMV DNAemia) of 47 monkeys was quantified by real-time PCR on a weekly to biweekly basis. As compared to other immunosuppressive regimens, and in association with greater decreases in WBC, lymphocyte, CD3+CD4+, and CD3+CD8+ lymphocyte counts, frequent CMV DNAemia occurred earlier (within the first month posttransplant), and was of greater severity and duration in recipients of TMG ± FLUD. Treatment of recipients with alternative induction agents that resulted in less dramatic reductions in WBC and lymphocyte counts, however, resulted in occurrence of CMV DNAemia after postoperative day 60. The frequency, average intensity, duration, and area under the curve (AUC) for CMV DNAemia in animals receiving TMG ± FLUD were 75–100%, 4.02 ± 1.75 copies/ng DNA, 23.0 ± 5.3 days, and 367.0 ± 121.1 days x copies/ng DNA, respectively; corresponding values in animals receiving other treatments (0–44%, 0.19 ± 0.10 copies/ng DNA, 0.5 ± 0.3 days, and 75.4 ± 40.2 days x copies/ng DNA, respectively) were significantly different. The value of WBC, T and B cells at the nadir of cell depletion greatly affects the occurrence of CMV DNAemia. No animals developed CMV DNAemia within the next 3 weeks when the lowest value of WBC, lymphocyte, CD3+, CD3+CD4+, CD3+CD8+, or CD20+ cells was above 4500, 1800, 300, 200, 150, or 300 cells/μl, respectively. Oral valganciclovir prophylaxis did not completely prevent the appearance of CMV DNAemia.

Abstract
Infection with cytomegalovirus (CMV) remains a significant cause of morbidity and mortality following allogeneic bone marrow transplantation (allo-BMT). The manifestations of CMV infection can range from neurological and haematological abnormalities to diminished graft survival and, in extreme cases, death. Many clinical studies have shown a direct correlation between cytomegalovirus infection and increased morbidity and mortality post allo-BMT, yet the exact mechanism is not well understood. Although driven primarily by T cell responses, the role of complement activation in acute and chronic graft-versus-host disease (GVHD) has also become more evident in recent years. The present studies were performed to examine the effects of murine cytomegalovirus (MCMV) infection on decay accelerating factor (DAF) and MCMVs role in exacerbating morbidity and mortality post-allo-BMT. Mice infected previously with a sublethal dose of MCMV (1 × 10⁵ plaque-forming units) have reduced expression of DAF on lung tissues and lymphocytes following allo-BMT. More importantly, mortality rates post-allo-BMT in recipient DAF knock-out mice receiving wild-type bone marrow are increased, similar to wild-type MCMV-infected recipient mice. Similarly, DAF knock-out mice showed greater intracellular interferon (IFN)-γ production by lung CD8 T cells, and infection with MCMV further exacerbated both intracellular IFN-γ production by CD8 T cells and mortality rates post-allo-BMT. Together, these data support the hypothesis that MCMV infection augments morbidity and mortality post-allo-BMT by reducing surface DAF expression.

Abstract
A prospective analysis of active Human Cytomegalovirus infection (HCMV) was conducted on 33 pediatric renal or hematopoietic stem cell post-transplant patients. The HCMV-DNA positive samples were evaluated for the prevalence of different gB subtypes and their subsequent correlation with clinical signs. The surveillance of HCMV active infection was based on the monitoring of antigenemia (AGM) and on a nested polymerase chain reaction (N-PCR) for the detection of HCMV in the patients studied. Using restriction analysis of the gB gene sequence by PCR-RFLP (Restriction Fragment Length Polymorphism), different HCMV strains could be detected and classified in at least four HCMV genotypes. Thirty-three pediatric recipients of renal or bone marrow transplantation were monitored. Twenty out of thirty-three (60.6%) patients demonstrated active HCMV infection. gB1 and gB2 genotypes were more frequent in this population. In this study, we observed that gB2 had correlation with reactivation of HCMV infection and that patients with mixture of genotypes did not show any symptoms of HCMV disease. Future studies has been made to confirm this.

Abstract
CMV infection is one of the major causes of morbidity and mortality after HSCT. The aim of this single center retrospective study was to analyze risk factors for CMV infection in pediatric patients who underwent HSCT. We retrospectively reviewed the medical records of 117 pediatric patients who underwent allogeneic HSCT at Asan Medical Center between December 2000 and January 2007. After HSCT, CMV antigenemia was detected by identifying CMV pp65 early antigen in white blood cells. The incidence of CMV antigenemia was 24% (28/117) at a median of 38 days (range: 19-123 days) after HSCT. In multivariate analysis, CMV antigenemia occurred significantly more often in CMV seropositive recipients, patients who received grafts from alternative donors, T-cell depleted grafts, patients on ATG-containing conditioning regimens, or patients who received steroid for acute GVHD (p < 0.05). CMV antigenemia tend to develop earlier in patients who received ATG-containing conditioning regimens (p = 0.09). A second episode of CMV antigenemia was observed in three out of 28 patients (11%). The incidence of CMV disease was 5.9% (7/117) at a median of 97 days (range: 34-120 days). Manifestation of CMV disease included retinitis in two, pneumonitis in two, hepatitis in one, hepatitis with colitis in one, and gastritis in one. Six of the 12 patients (50%) with HG antigenemia (CMV pp65 antigen positivity > or =40 cells) developed clinical CMV disease, a rate that was significantly higher than seen in patients with LG antigenemia (6.25%; p < 0.01). We recommend that patients with these risk factors should carefully undergo regular evaluations for CMV infection. We also suggest that earlier and more aggressive preemptive treatment and serial follow-up of CMV disease is necessary in patients with HG-antigenemia.

Abstract
Infectious complications remain an important cause of death in hematopoietic stem cell transplant (HSCT) recipients. We undertook a 20-year (1988-2007) retrospective review of all autopsies performed on HSCT recipients in our institution, with emphasis on infections, especially fungal infections, as the cause of death. Of the 2,943 autopsies performed in our institution from 1988 to 2007, 395 (13.4%) involved HSCT recipients (117 pediatric; 278 adult). Of the patients, 298 had received allogeneic, 46 autologous, 41 umbilical cord blood, and 3 autologous plus allogeneic types, and 7 were unknown HSCT types. The most common causes of death were pulmonary complications, occurring in 247 (62.5%) of 395 cases. In 178 cases (45.1%), microorganisms (viral, bacterial, and/or fungal) were documented at autopsy in one or more organs and contributed to the cause of death. Fungal infections were found in 23.5% of cases, but their frequency as a cause of death decreased throughout this study, from 30.3% in the 1988-1992 period to 10.9% in the 2003-2007 period.

Abstract
This study investigated the impact of pretransplant cytomegalovirus (CMV) serostatus and posttransplant CMV reactivation and disease on umbilical cord blood transplant (UCBT) outcomes. Between 1994 and 2007, 332 patients with hematologic malignancies underwent UCBT and 54% were CMV seropositive. Pretransplant recipient CMV serostatus had no impact on acute or chronic graft-versus-host disease (aGVHD, cGVHD), relapse, disease-free survival (DFS), or overall survival (OS). There was a trend toward greater day 100 treatment-related mortality (TRM) in CMV-seropositive recipients (P=.07). CMV reactivation occurred in 51% (92/180) of patients with no difference in myeloablative (MA) versus reduced-intensity conditioning (RIC) recipients (P=.33). Similarly, reactivation was not influenced by the number of UCB units transplanted, the degree of HLA disparity, the CD34(+) or CD3(+) cell dose, or donor killer cell immunoglobulin-like receptor (KIR) gene haplotype. Rapid lymphocyte recovery was associated with CMV reactivation (P=.02). CMV reactivation was not associated with aGVHD (P=.97) or cGVHD (P=.65), nor did it impact TRM (P=.88), relapse (P=.62), or survival (P=.78). CMV disease occurred in 13.8% of the CMV-seropositive patients, resulting in higher TRM (P=.01) and lower OS (P=.02). Thus, although recipient CMV serostatus and CMV reactivation have little demonstrable impact on UCB transplant outcomes, the development of CMV disease remains a risk, associated with inferior outcomes.

Abstract
OS is a variant of SCID characterized by generalized erythroderma, alopecia, eosinophilia, and elevated IgE levels. It is fatal unless treated with allogeneic HSCT, which is the only curative approach. However, treatment related complications and graft rejection are major obstacles to the success of treatment. In this report, we describe a patient with OS, complicated by prolonged cytomegalovirus infection, successfully treated by reduced intensity conditioning allogeneic HSCT from sibling donor.

Abstract
Pulmonary complications resulting in high morbidity and mortality occur in a substantial proportion of hematopoietic stem cell transplantation (HSCT) recipients. We investigated the incidence, causes, and risk factors of pulmonary complications, early after HSCT in pediatric patients, and patient outcomes by retrospective analysis of patients who underwent HSCT at Seoul National University Children's Hospital between September 2003 and June 2007. A total of 145 patients were evaluated of whom 15 (10.3%) developed pulmonary complications. Eight patients were suspected to have infection-related pulmonary complications and 7 had noninfectious causes. In a multivariate analysis of allogeneic transplantation recipients, detection of cytomegalovirus antigenemia was significantly associated with the development of both pulmonary complications and acute respiratory distress syndrome. Eleven (73.3%) of the 15 patients developed acute respiratory distress syndrome, required mechanical ventilation and eventually died. Early use of methylprednisolone in 3 patients decreased the oxygenation index. Sixteen patients died due to treatment-related complications early after HSCT, and pulmonary complications accounted for a substantial portion of the mortality. Thus, improvement of prophylaxis and management for pulmonary complications is crucial to improve the overall outcome of HSCT. More aggressive prophylaxis and treatment of cytomegalovirus infection and judicious use of methylprednisolone at the appropriate time could be the means for such improvement.

Abstract
Pulmonary complications after allogeneic hematopoietic stem-cell transplantation (HSCT) remain 1 of the most important causes of morbidity and mortality. This study evaluates the change over time of incidence, aetiology and risk factors for death related to pneumonia within 3 months after HSCT. 997 patients who underwent HSCT were studied retrospectively. Most patients (83%) had a haematological malignancy. The majority (89%) had an HLA-A, -B, and -DR matched related or unrelated donor. Conditioning consisted of cyclophosphamide and total-body irradiation or busulfan and graft-versus-host disease prophylaxis of cyclosporin and methotrexate in most cases. Death related to pneumonia occurred in 56 (5.6%) patients. Cytomegalovirus (37%) was the main pathogen involved, especially during the first 2 decades studied. In the multivariate risk factor analysis, we found that death from pneumonia was significantly associated with receiving a T-cell depleted graft (p<0.001), bacteraemia (p=0.001), and y of transplantation (p<0.001). In patients receiving a transplant during the last decade, the incidence of death related to pneumonia was 2.8% compared to 8.9% during the first decade. We conclude that the rate of mortality related to pneumonia has decreased over time, possibly as a result of improved diagnostic, prophylactic and therapeutic methods and treatment.

Abstract
BACKGROUND Little is known about the clinical importance of cytomegalovirus (CMV) antigenemia for intrauterine-CMV-infected newborns. The aims of the present study were to evaluate the diagnostic accuracy of CMV antigenemia during the neonatal period and its association with clinical manifestations. METHODS CMV antigenemia was analyzed using neonatal blood from 25 patients suspected of having intrauterine infection because of abnormal clinical manifestations in the mother, fetus, and newborn. Neonatal urine samples were collected for diagnosis of intrauterine infection. The diagnostic accuracy of the antigenemia analysis was evaluated by comparing it with the results of urinary CMV analyses. The clinical manifestations of antigenemia-positive and -negative infected newborns were compared in the infected newborns. RESULTS Fifteen newborns were congenitally infected and 10 were uninfected as diagnosed on virus isolation from neonatal urine. Six of 15 infected newborns were positive for CMV antigenemia. CMV antigenemia had a positive predictive value of 100%, a negative predictive value of 52.6%, a sensitivity of 40%, and a specificity of 100%. CMV retinitis and pneumonitis were more prevalent among antigenemia-positive newborns (4/6) than antigenemia-negative newborns (0/9; P < 0.05). CONCLUSIONS Antigenemia was significantly associated with retinitis and pneumonia, but it was not sensitive enough to diagnose intrauterine CMV infection.

Abstract
Pulmonary complications are among the most common and serious sequelae seen in hematopoietic stem cell transplantation (HSCT) recipients. This two-part review addresses the incidence and impact of pulmonary complications in pediatric HSCT patients. In this first part we review the available data for the use of diagnostic modalities in this population, including flexible bronchoscopy with bronchoalveolar lavage (BAL) and open lung biopsy (OLB). We also review the many infectious pulmonary complications that may occur in pediatric HSCT recipients, utilizing the traditional chronologic divisions of neutropenic phase (0-30 days following HSCT), early phase (30-100 days), and late phase (>100 days).

Abstract
OBJECTIVE This study was designed to investigate the effect of allogeneic haematopoietic stem cell transplantation (HSCT) on cytomegalovirus (CMV) shedding in the saliva by nested polymerase chain reaction (nested PCR) and its impact on patient survival. PATIENTS AND METHODS One hundred and twenty-four HSCT patients and 124 healthy volunteers were included in the study. Oral swabs were taken before, after 100 days and 1 year of HSCT at the buccal mucosa. Nested PCR was used to detect CMV in the saliva. Time of death after HSCT was displayed, by means of the Kaplan-Meier method, for the following parameters: age and gender of the patient, donor gender, primary disease, stem cell source, platelet number, chronic graft vs host disease (cGVHD) of salivary glands and oral mucosa, and oral CMV shedding. Cox proportional hazards model was used for multivariate survival analysis. RESULTS While none of the individuals in the control group showed positive swabs for CMV, the frequency of positive CMV oral swabs in patients at day + 100 after HSCT (45.2%) was statistically higher than before (7.2%) and 1 year after HSCT (17.5%). The presence of CMV was not associated with cGVHD and did not have any impact on post-transplant survival. CONCLUSIONS The present study shows that oral CMV shedding occurs after HSCT, especially at day +100 post-transplant. Identification of CMV in the saliva might be important for the early diagnosis of CMV infection in allo-HSTC.

Abstract
Cytomegalovirus (CMV) poses a threat to the therapy of hematopoietic malignancies by hematopoietic stem cell transplantation, but efficient reconstitution of antiviral immunity prevents CMV organ disease. Tumor relapse originating from a minimal residual leukemia poses another threat. Although a combination of risk factors was supposed to enhance the incidence and severity of transplantation-associated disease, a murine model of a liver-adapted B-cell lymphoma has previously shown a survival benefit and tumor growth inhibition by nonlethal subcutaneous infection with murine CMV. Here we have investigated the underlying antitumoral mechanism. Virus replication proved to be required, since inactivated virions or the highly attenuated enhancerless mutant mCMV-DeltaMIEenh did not impact the lymphoma in the liver. Surprisingly, the dissemination-deficient mutant mCMV-DeltaM36 inhibited tumor growth, even though this virus fails to infect the liver. On the other hand, various strains of herpes simplex viruses consistently failed to control the lymphoma, even though they infect the liver. A quantitative analysis of the tumor growth kinetics identified a transient tumor remission by apoptosis as the antitumoral effector mechanism. Tumor cell colonies with cells surviving the CMV-induced "apoptotic crisis" lead to tumor relapse even in the presence of full-blown tissue infection. Serial transfer of surviving tumor cells did not indicate a selection of apoptosis-resistant genetic variants. NK cell activity of CD49b-expressing cells failed to control the lymphoma upon adoptive transfer. We propose the existence of an innate antitumoral mechanism that is triggered by CMV infection and involves an apoptotic signal effective at a distant site of tumor growth.

Abstract
PURPOSE Extracorporeal membrane oxygenation (ECMO) is a means of respiratory and hemodynamic support for patients failing conventional therapies. Children requiring hematopoietic stem cell transplantation who develop complications during therapy may require ECMO. Such patients pose medical and ethical challenges for clinicians considering initiation of ECMO. The authors review the outcomes of these patients and propose recommendations. METHODS The Extracorporeal Life Support Organization Registry was queried for all patients younger than 18 years with an International Classification of Diseases, Ninth Revision, or Current Procedural Terminology code related to bone or stem cell transplant. RESULTS Nineteen children in the registry met inclusion criteria. The median age was 9.6 years (7 months to 17.5 years). Initiation of ECMO was for pulmonary support (n = 17), cardiac support (n = 1), or cardiopulmonary resuscitation (n = 1). The median duration of ECMO support was 5.1 days (range, 30 hours to 42 days). Pulmonary infections included 3 parainfluenza, 2 Pneumocystis carinii, 1 influenza A, and 1 respiratory syncytial virus. Overall, 15 (79%) died during their ECMO run, whereas only 4 (21%) survived to come off ECMO. Furthermore, of those who survived their ECMO run, only one patient survived to discharge from the hospital. Risk factors for death on ECMO include development of renal complications and development of multiorgan dysfunction. CONCLUSION Patients who require ECMO for cardiopulmonary support after hematopoietic stem cell transplantation have a poor prognosis. Clinicians must be cautious in presenting this option to parents and present them with appropriate expectations in this high-risk population.

Abstract
Human cytomegalovirus (HCMV) and human herpesvirus-6 (HHV-6) are two closely related viruses, which belong to the Herpesviridae family. Following primary infection, they are thought to persist for life as latent forms in mononuclear cells. HCMV and HHV-6 can cause considerable morbidity in immunocompromised individuals, such as transplant patients. A sensitive and specific LightCycler multiplex real-time PCR assay based on fluorescence energy transfer (known as FRET) was developed. This assay, by using two sets of hybridization probes specific for HHV-6 (A and B) and HCMV, can differentiate reliably and quantify simultaneously both viruses in order to diagnose reactivation processes. The assay was optimized and the lower limit of detection for both viruses was determined to be 10 viral genome copies per reaction. Both viruses were quantified in 83 peripheral blood mononuclear cells (PBMCs) and 87 polymorphonuclear leukocytes (PMNLs) collected from 32 transplant recipients. This multiplex real-time quantitative PCR was finally compared with two other quantitation and detection assays used daily in laboratory (PCR DIG detection and antigenemia for HCMV, TaqMan Assay for HHV-6). This technique can be useful for the differentiation and quantitation of HCMV and HHV-6 for monitoring transplant patients.

Abstract
We studied the clinical profile of infections among 221 pediatric patients who underwent 230 allogeneic transplants between 1986 and June 2004. All patients developed febrile neutropenia. There were 283 documented infections, which included bacterial (36.9%), viral (45.7%), fungal (11.1%) and other infections (6.3%) including tuberculosis. Bacterial and fungal infections were more common in the first 30 days following BMT, while viral infections were more common >30 days after BMT. Bacterial pathogens were predominantly gram-negative organisms (72.7%), when compared with gram-positive organisms (27.3%). Common gram-negative organisms included NFGNB, Pseudomonas, Escherichia coli and Klebsiella while coagulase negative Staphylococci was the main gram-positive organism. Bacteremia (61.2%) was the main source positive cultures and was mainly because of gram-negative organisms (81%), predominantly NFGNB and Pseudomonas. Exactly 103/221(43.7%) transplants had 128 documented viral infections commonly because of Cytomegalovirus, Herpes group of viruses and transfusion related hepatitis. Thirty of 221 (13.5%) of transplants had 30 documented fungal infections with the majority being because of aspergillus (90%). Tuberculosis was seen in 1.7% of transplants while catheter infections were seen in 21 patients (9.1%). Infection related mortality was seen in 12% predominantly because of CMV or fungal infections. A sub group analysis (pre-1998 vs. post-1998) revealed higher incidences of gram-negative infections, bacteremia and bacterial infection related mortality in the pre-1998 era when compared with the recent times. The profile and mortality of infections in this series from India is not significantly different from reports from the West.
