Abstract
In contrast to transplant recipients, there is a paucity of data regarding frequency and clinical significance of viraemia in children receiving conventional chemotherapy. In a prospective observational study, we assessed the frequency of and clinical impact of viraemia with cytomegalovirus (CMV), Epstein-Barr virus (EBV), adenovirus, human herpesvirus-6 (HHV6) and herpes-simplex virus 1/2 (HSV1/2) in paediatric cancer patients at diagnosis, at a routine examination during intensive chemotherapy, and during febrile neutropenia (FN). Seventy-nine patients (median age 6 years; 66 children with haematological malignancies) were included in the study. Overall, 362 blood samples were analysed, 72 from the time at diagnosis (11.1% with positive PCR result), 118 during a regular control after chemotherapy (11.0% positive), and 159 during FN (8.8% positive). The overall positivity rate was 9.6% (CMV 3.3%, HHV6 2.7%, HSV 2.2%, EBV 0.8% and adenovirus 0.3%). There were no significant differences between FN episodes with and without viraemia in terms of duration of fever or neutropenia/lymphopenia, severity of mucositis (> II0), incidence of diarrhea and ICU admission. Our results indicate that viraemia in paediatric cancer patients generally does not have a major clinical impact, and may help in the decision regarding the indication of routine evaluation for viraemia in febrile neutropenic, but otherwise asymptomatic children.

Abstract
Acute lymphoblastic leukemia is predominately a childhood disease and around two third of cases are of B-cell phenotype. Cytomegalovirus is an important cause of morbidity and mortality in allogeneic hematopoietic progenitor cell transplant; however, it is rare in patients with B-cell acute lymphoblastic leukemia in non-transplant settings. In this study, we evaluated 72 patients of acute precursor (pre) B-cell acute lymphoblastic leukemia at Shaukat Khanum Memorial Cancer Hospital and Research Center, out of which three were positive for Cytomegalovirus.

Abstract
Cytomegalovirus (CMV) reactivation is well known in post-transplant immunocompromised children. However, the incidence in non-transplant patients is significantly less, and only scarce case reports are available in the literature regarding CMV disease in children with solid tumors. We present a 3-year-old male child with multisystem refractory Langerhans cell histiocytosis, who had very high CMV viremia and disseminated CMV infection with secondary hemophagocytic lymphohistiocytosis and was successfully treated without organ damage and sequelae. Although routine screening is not recommended, CMV viremia/disease needs to be considered in non-transplant immunocompromised children with multisystem involvement with unexplained cytopenia.

Abstract
BACKGROUND Cytomegalovirus infection represents a significant cause of morbidity and mortality after hematopoietic stem cell transplantation. This study aimed to evaluate the incidence of viremia and disease due to cytomegalovirus and the risk factors in pediatric patients with hematopoietic stem cell transplantation in our institution. METHODS This was a retrospective cohort of patients under 19 years of age who underwent allogeneic hematopoietic stem cell transplantation due to any indication between 2012 and 2019. The analysis included the diagnosis of cytomegalovirus viremia or disease during post-transplant follow-up, evaluation of risk factors, and outcomes. The statistical analysis included univariate and multivariate analyses, and the cumulative incidence of cytomegalovirus viremia was determined by the Kaplan-Meier method using STATA 14 statistical software. RESULTS A total of 182 transplants were included. At 100 days, the cumulative incidence of cytomegalovirus viremia was 70.5%, and that of cytomegalovirus disease was 4.7%. Overall survival at 2 years was 74%, and event-free survival was 64%. The remaining demographic characteristics were not predictors of infection. There was no association between viremia and relapse or survival of the patients. Higher mortality was noted in cytomegalovirus disease. CONCLUSIONS During the study period, the incidence of cytomegalovirus disease was similar to that of other pediatric reports, but the incidence of viremia was higher. Pre-emptive therapy has diminished disease rates and death due to infection. Viral load cutoff points should be standardized to guide treatment and avoid myelotoxicity.

Abstract
INTRODUCTION Cytomegalovirus (CMV) infections in developing countries are experienced at an early age. This study was performed to investigate the frequency of reactivation and risk factors of infection acquired at an early age of nontransplant acute lymphoblastic leukemia (ALL) patients receiving immunosuppressive therapy with weekly monitoring of CMV levels in Turkey. MATERIALS AND METHODS This was a retrospective, single-center study of 172 pediatric patients (102 boys and 70 girls) with ALL. All patients were monitored routinely for CMV-DNA at the initial presentation of leukemia and twice a week during chemotherapy. The CMV immunoglobulin (Ig)M/IgG titers were measured at admission. RESULTS CMV seropositivity at baseline was 90,11%. The overall prevalence of CMV infection (viremia) was 70.34%, 116 of whom were seropositive for CMV IgG and 5 of whom were negative for CMV at the time of ALL diagnosis. Reactivation was more common than de novo CMV infections (P=0.000). CMV seropositivity at the beginning of the leukemia diagnosis was found to be an independent predictor for developing CMV infection (P=0.001). A total of 60 CMV infection episodes were treated with antivirals. Four of these included organ involvement. The duration of CMV-DNA viremia episodes was longer in patients with CMV-DNA ≥1000 copies/mL (n=45) than in those with lower CMV-DNA levels (P=0.002). Infection was shown not to be associated with chemotherapy phase. CONCLUSION This study suggests the importance of monitoring for CMV infections in developing countries because of frequent reactivations in seropositive ALL patients. It should be kept in mind that low CMV-DNA levels may also lead to organ involvement.

Abstract
Introduction Cytomegalovirus (CMV) predisposes to several clinical complications and is a major cause of morbidity and mortality in immunocompromised patients, including patients with hematological malignancies (HM). The present study was carried out to determine the distribution of CMV glycoprotein B, N, and O (gB, gN, and gO) genotypes and their potential effect on its viral load and on clinical outcomes in a cohort of Tunisian non-hematopoietic stem cell transplant (HSCT) patients with HM undergoing chemotherapy. Methods CMV viral load was evaluated by real-time quantitative PCR. The gB, gN, and gO genotypes of the CMV strains were analyzed by multiplex nested PCR and sequencing. Results This prospective study involved 60 clinical isolates obtained from 60 non-HSCT patients with HM undergoing chemotherapy. Mixed CMV gB, gN, and gO genotypes were the predominant glycoprotein genotypes in 31%, 41.4%, and 46.4% of patients, respectively. Mixed gB genotypes were associated with higher initial levels of CMV load (p = 0.001), increased rate of fever (0.025), and co-infection with other herpesviruses (HHVs) (p = 0.024) more frequently than in single gB genotype. Mixed gN genotypes were more associated with severe lymphopenia (ALC < 500/µL) (p = 0.01) and increased risk of death (p = 0.042) than single gN genotype. Single gO2b genotype had also a more unfavorable outcome (p = 0.009) than the other single gO genotype. Mixed gO genotypes were associated with female gender (p = 0.015), acute leukemia disease (p = 0.036), initial high level of CMV viral load (at least 1000 copies/mL) (p = 0.029), skin rash (p = 0.01) more frequently than in single gO genotype. The gO1a/gN3b linkage was associated with an increased initial viral load (p = 0.012). Conclusion Infection with mixed CMV genotypes was common and multiple gB, gN, and gO genotypes were associated with clinical manifestation and higher viral load.

Abstract
Purpose The aim of this study was to describe the clinical features, course, and clinical outcomes of eyes with cytomegalovirus (CMV) retinitis in immunosuppressed patients of different etiologies. Methods This was a retrospective observational study from a single ophthalmic tertiary care center. The patients included referrals from the nodal cancer center and the local human immunodeficiency virus (HIV) treatment clinic. Demographics, history, visual acuity, ocular features, treatment protocol, and final visual outcome of patients who were diagnosed with CMV retinitis in the period of five years from 2014 to 2019 were studied. Results CMV retinitis was diagnosed in 25 eyes of 14 patients. Age of the patients ranged from 11-54 years. Ten (71.43%) patients were male and four (29.57%) were female. Eight of them had acute lymphoblastic leukemia (ALL), four were suffering from HIV infection and one patient each had lymphoma and history of a kidney transplant. The treatment for CMV retinitis ranged from two to sixty weeks depending on disease activity and systemic condition. Three of the patients were on maintenance therapy for ALL at the time of reactivation. Conclusion Duration of treatment for CMV retinitis in patients of ALL was longer as compared to the other etiologies, and in recurrences, it needed to be continued till the completion of maintenance therapy for ALL. It is prudent to advise regular ophthalmic screening of all immunocompromised patients, as they are at a high risk of developing CMV retinitis. Patients of ALL, especially while on maintenance therapy, should be monitored for possible development or reactivation of CMV retinitis.

Abstract
Among acute lymphoblastic leukemia (ALL), 40% of affected patients are diagnosed after the age of 20. Compared to pediatricians, adult hemato-oncologists are less familiar with complex pediatric ALL regimens and have perceived that pediatric ALL regimens are too toxic in the adult population. Meanwhile, multiple retrospective analyzes showed the superiority of pediatric regimens among the older adults and young adolescents (AYAs) group over adult regimens. A series of prospective studies have made it apparent that pediatric-inspired ALL regimens are feasible in AYAs, with manageable toxicities and potentially more encouraging results. However, the complications in the adult population are still to be explored. Although cytomegalovirus (CMV) viremia and infections are increasingly recognized in pediatric ALL cases, we generally do not experience it frequently in adult cases with conventional strategies. Herein we represent a 38-year-old man diagnosed with ALL and treated with pediatric inspired GRAALL-2003 protocol. Following a successful induction phase, he had pancytopenia, deep lymphopenia, fever and diarrhea in the 9th month of maintenance therapy. With increased serum ferritin and triglyceride levels, he had features of macrophage activation syndrome. The bone marrow biopsy did not reveal any relapse or hemophagocytosis. We detected highly increased levels of CMV DNA (657.262 copies/mL) in blood analysis.

Abstract
Systemic viral diseases frequently occur in allogeneic hematopoietic stem cell transplantation, but data in children receiving chemotherapy for acute leukemia are scarce. We therefore collected and analyzed the published data on symptomatic infection from cytomegalovirus, herpes simplex virus, varicella zoster virus, parvovirus B19, or adenovirus in pediatric acute leukemia. Reports on 68 children were identified, of whom 16 patients have died from the infection. Further studies have to (1) evaluate the true incidence of these infections in pediatric acute leukemia, (2) their impact on outcome, and (3) whether a subpopulation of patients could benefit from screening and prophylactic strategies.

Abstract
BACKGROUND Concurrent cytomegalovirus (CMV) in inflammatory bowel disease (IBD)-related colitis is an important scenario associated with high rates of colectomy and other morbidity. Due to the low incidence of CMV, testing of all patients is associated with an unacceptably high consumption of resources and delay in treatment. Therefore, several predictive scores have been developed to identify patients at risk for a CMV infection. METHODS We performed a retrospective single center study in a German University hospital including all IBD patients with available data on CMV-PCR analysis in whole blood between 2010 and 2018 and evaluated 2 prognostic scores for CMV infection for their diagnostic accuracy. RESULTS In the study, 907 patients with IBD and CMV-PCR were identified. Of them, 21 patients (2.3 %) had a positive CMV-PCR (≥ 1000 copies/mL), 14 of them in ulcerative colitis and 7 in Crohn's disease. The Berlin Score identified 667 patients (73.1 %) as potentially CMV-positive, resulting in a positive predictive value of 2.5 % and a negative predictive value of 98.3 %. In contrast, the Münster Score identified 60 patients as potentially CMV-positive, resulting in a PPV of 20 % and an NPV of 99.4 %. CONCLUSIONS Scoring systems can help to identify patients at risk for a CMV infection and minimize resource consumption and delay in treatment. Due to low incidence, a 2-step-algorithm, consisting of the Münster Score followed by a CMV-PCR if the score indicates a CMV infection, is preferable.

Abstract
Background Human herpesviruses (HHVs) remain latent after primary infection and can be reactivated in response to immunosuppression and chemotherapy. Little is known about their incidence, potential relationships, risk factors and clinical impact in non-transplant leukemia patients. This study investigated prospectively incidence, risk factors, clinical impact and possible association of HHVs-(1–7) infections in patients with newly diagnosed acute leukemia. Methods Study design involved longitudinal sampling before chemotherapy and in different phases of chemotherapy: post-induction, post-remission, and post-salvage during 2016–2018. A total of 734 plasma samples from 95 patients were analyzed by a qualitative, multiplex PCR for HHVs detection and a quantitative real-time PCR was used for cytomegalovirus (CMV) quantification. HHVs-(1–6) IgG and IgM antibodies were tested using immunoassays. Risk factors were analyzed by binary logistic regression and relationships between viruses were analyzed using the Chi-square or Fisher’s exact test as appropriate. Results The overall seroprevalences of HHV-(1–6) IgG were high (> 80%). At least one herpes viral agent was detected in 60 patients (63.3%). CMV was the most commonly detected virus in the different phases of chemotherapy (19.4%), followed by HHV-6 (9.7%), HHV-7 (5.2%) and EBV (2.7%). HSV-1/2 and VZV DNA were not detected. Twenty-seven patients (28.4%) had more than one virus detected in the follow-up, with 23 who were co-infected. CMV/HHV-6 was the most frequent co-infection (69.5%, 16/23). HHV-6 infection (p = 0.008) was identified as a risk factor for CMV infection while salvage treatment (p = 0.04) and CMV infection (p = 0.007) were found to be independent risk factors for HHV-6 infection. CMV co-infection was associated with severe lymphopenia with an absolute lymphocyte count (ALC) (< 500/μL) (p = 0.009), rash (p = 0.011), pneumonia (p = 0.016) and opportunistic infections [bacteremia, p < 0.001 and invasive fungal infection, (p = 0.024)] more frequently than CMV mono-viral infections. Conclusions Our data suggest that co-infection with HHVs, especially CMV and HHV-6, may contribute to the development of serious clinical manifestations with profound lymphopenia, pneumonia rash and increased risk for bacterial and fungal co-infections. These findings may suggest the synergistic effect of HHVs associated infection.

Abstract
BACKGROUND Cytomegalovirus (CMV) disease is underrecognized in children with retinoblastoma. This study investigated rates of CMV infection and disease in this specific population receiving chemotherapy. METHODS From a cohort of 164 patients with retinoblastoma diagnosed from 2011 to 2018, 107 patients were evaluated for CMV infection determined by antigenemia assay or real-time PCR. Preemptive CMV screening was implemented in 2013. CMV disease was diagnosed by tissue biopsy, culture, or ophthalmic examination. RESULTS Thirty-seven and 70 patients before and after the screening strategy, respectively, were included. Before screening, 10/37 (27%) were diagnosed with CMV infection during chemotherapy. Among them, 5 (50%) developed CMV disease (hepatitis, pneumonia, and retinitis) and one patient died of CMV pneumonia. During screening, 18/70 (26%) were documented with 36 episodes of CMV infection and 9 patients received 25 preemptive antiviral therapies. Age at chemotherapy tended to be younger in patients with CMV infection, and fewer were seronegative prior to chemotherapy. Patients who started chemotherapy at <12 months of age received preemptive therapies significantly more often than those started at ≥12 months. Two (11%) out of 18 patients with CMV infection developed CMV retinitis and colitis, and there were no fatal cases. Preemptive therapy along with active CMV screening significantly reduced the risk of developing CMV disease, from 14% to 2.9% (P = 0.047). CONCLUSIONS Children with retinoblastoma can experience significant morbidity and even mortality from CMV infection during chemotherapy in Korea. Preemptive screening and appropriate antiviral therapy can reduce the development of CMV disease and subsequent mortality.

Analysis of Ganciclovir-Resistant Cytomegalovirus Infection Caused by the UL97 Gene Mutation in Codons 460 and 520 in Pediatric Patients: A Case Series. Open Forum Infect Dis 2019; 6:ofz480. [PMID: 32528998 PMCID: PMC7275293 DOI: 10.1093/ofid/ofz480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Accepted: 10/31/2019] [Indexed: 11/14/2022] Open
Abstract
Background Drug-resistant cytomegalovirus (CMV) infection has been increasingly recognized. However, there are limited data in pediatric patients. In this study, the prevalence and factors associated with CMV infection with UL97 mutations in pediatric patients treated with ganciclovir but not responding to treatment were evaluated. Methods This retrospective study was conducted from January 2013 to December 2017. All patients who were suspected of having ganciclovir-resistant CMV infection and had never had ganciclovir prophylaxis were included. Genotypic assay for UL97 mutations in codons 460 and 520 conferring ganciclovir resistance was performed. Factors associated with the presence of UL97 mutations were analyzed. Results Of 34 patients included, 10 patients (29.4%) had a genotypically confirmed UL97 mutation. The median age (interquartile range [IQR]) was 3 (0.85–8.68) years. Ganciclovir resistance was tested at a median time (IQR) of 22.5 (14.3–31) days after initiation of ganciclovir. All resistant isolates harbored a UL97 mutation in codon 460. Compared with patients infected with CMV without UL97 mutation, those infected with UL97 mutation strains were younger (median age [IQR], 3.02 [0.85–8.68] vs 10.45 [2.7–16.4] years) and had a higher maximum viral load (median [IQR], 5.06 [4.74–6.05] vs 4.42 [4.03–4.87] copies/mL). Six of 10 (60%) patients were successfully treated with high-dose ganciclovir (7.5 mg/kg twice daily). Conclusions UL97 mutation ganciclovir-resistant CMV infection was not uncommon in the pediatric population. Screening for this mutation should be considered in patients experiencing virological worsening while ganciclovir is given, even if patients have not previously received ganciclovir prophylaxis.
