Abstract
OBJECTIVE To identify the type of infections and risk factors for infection-related mortality (IRM) after allogeneic hematopoietic stem cell transplantation (HSCT). METHODS Retrospective cohort study of patients <16 years of age treated in 2010-2019 was conducted. Unadjusted hazard ratios (HR) and adjusted hazard ratios (aHR) with 95% confidence intervals (95% CIs) were estimated using Cox regression. Cumulative incidence was calculated. RESULTS Data for 99 pediatric patients were analyzed. The myeloablative conditioning was the most used regimen (78.8%) and the hematopoietic stem cell source was predominantly peripheral blood (80.8%). Primary graft failure occurred in 19.2% of patients. Frequency of acute graft-versus-host disease was 46.5%. Total of 136 infectious events was recorded, the most common of which were bacterial (76.4%) followed by viral infection (15.5%) and then fungal infection (8.1%). The best predictors for infection subtypes where the following: a) for bacterial infection (the age groups of 10.1-15 years: aHR = 3.33; 95% CI: 1.62-6.85 and. >15 years: aHR = 3.34; 95% CI: 1.18-9.45); b) for viral infection (graft versus host disease: aHR = 5.36; 95% CI: 1.62-17.68), however, for fungal infection statistically significant predictors were not identified. Related mortality was 30% (n = 12). Increased risk for infection-related mortality was observed in patients with unrelated donor and umbilical cord stem cells recipients (HR = 3.12; 95% CI: 1.00-9.85). CONCLUSIONS Frequencies of infections and infection-related mortality appear to be similar to those reported. Unrelated donors and stem cells from umbilical cord recipients were associated with a high risk of mortality.

Norovirus and sapovirus infections after allogeneic hematopoietic stem cell transplantation: is it worth it to look for them? Leuk Lymphoma 2023; 64:1295-1303. [PMID: 37165601 DOI: 10.1080/10428194.2023.2211186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 12/26/2022] [Accepted: 04/04/2023] [Indexed: 05/12/2023]
Abstract
Norovirus (NoV) and Sapovirus (SaV) are potential causative agents of diarrhea after allogeneic HSCT but little is known in this population. We performed a retrospective analysis by RT-PCR of calicivirus (NoV and SaV), Human adenovirus (HAdV), rotavirus (RV), Aichi virus (AiV), enterovirus (EV), human parechovirus (HPeV) and Human bocavirus (HBoV) in the diarrheal stools of patients after allogeneic HSCT. 49/162 patients had positive viral assays: HAdV (17%), EV (7%), NoV (4.3%), RV and HBoV (3.1% each), SaV (1.9%), AiV (1.2%), HPeV (0.6%). Seven patients were positive for NoV and 3 for SaV. Among viruses-positive samples, the frequency of caliciviruses cases was 7% in the 6 months post-HSCT compared to 40% after (p < 0.0001). The median duration of symptom was 0.7 months but 2 cases, occurring more than one year after HSCT, were chronic, undiagnosed and strongly contributed to morbidity. Systematic testing of caliciviruses appears especially useful in late chronic diarrhea.

Abstract
PURPOSE Mucositis is a frequent and severe complication in haematopoietic stem cell transplantation (HSCT). The effectiveness of probiotics in mucositis has been indicated by several clinical trials, but the results are still controversial. To date, studies on the influence of probiotics in HSCT are limited. Therefore, we conducted this retrospective study to evaluate the impact of viable Bifidobacterium tablets on the incidence and duration of chemotherapy-/radiation-induced mucositis in patients undergoing HSCT. METHODS Clinical data of 278 patients who underwent HSCT between May 2020 and November 2021 were retrospectively analysed. They were divided into a control group (138) and a probiotic group (140) according to whether they took viable Bifidobacterium tablets. First, we analysed the baseline data of the two groups. Then, we compared the incidence, severity and duration of mucositis between the two groups by using Mann-Whitney U test, chi-square test and Fisher's exact test according to the type of data. In order to exclude the influence of confounding factors, we further evaluated the efficacy of oral probiotics in preventing oral mucositis by Binary logistic regression analysis. RESULTS The use of viable Bifidobacterium tablets markedly reduced the incidence of oral mucositis (OM) (62.9% vs. 81.2%, p = 0.001) and mainly reduced the incidence of grades 1-2 OM (74.6% vs. 58.6%, p = 0.005). There was no significant difference in the incidence of severe (grades 3-4) OM between the two groups (6.5% vs. 4.3%, p = 0.409). The median duration of OM was shorter in the probiotic group (10 vs. 12 days, p = 0.037). The incidence and duration of diarrhoea did not differ between the two groups. Moreover, the use of viable Bifidobacterium tablets had no influence on engraftment. CONCLUSIONS Our results suggested that viable Bifidobacterium tablets could effectively reduce the incidence of grades 1-2 OM and duration of OM during the transplant process without affecting the outcome of HSCT.

Abstract
Norovirus (NoV) is the leading cause of viral-related diarrhea in cancer patients, in whom it can be chronic, contributing to decreased quality of life, interruption of cancer care, malnutrition, and altered mucosal barrier function. Immunosuppressed cancer patients shed NoV for longer periods of time than immunocompetent hosts, favoring quasispecies development and emergence of novel NoV variants. While nucleic acid amplification tests (NAATs) for NoV diagnosis have revolutionized our understanding of NoV burden of disease, not all NAATs provide information on viral load or infecting genotype. There is currently no effective antiviral or vaccine for chronic NoV infections. Screening for inhibitors of NoV replication in intestinal organoid culture models and creation of NoV-specific adoptive T cells are promising new strategies to develop treatments for chronic NoV in immunosuppressed patients. Herein we summarize data on the epidemiology, clinical manifestations, diagnostic challenges, and treatment of NoV infection in patients with cancer.

Abstract
Infectious gastroenteritis is common after transplantation and can lead to increased morbidity and mortality. A wide range of organisms can lead to gastroenteritis in this patient population. Clostridioides difficile, cytomegalovirus, and norovirus are the most common pathogens. Newer diagnostic methods, especially multiplex polymerase chain reaction, have increased the diagnostic yield of infectious etiologies. In this review, we describe the epidemiology and risk factors for common infectious pathogens leading to gastroenteritis.

Abstract
BACKGROUND Acute gastroenteritis (AGE) in hematopoietic cell transplant (HCT) patients causes significant morbidity and mortality. Data regarding the longitudinal assessment of infectious pathogens during symptomatic AGE and asymptomatic periods, particularly in children, are limited. We investigated the prevalence of AGE-associated infectious pathogens in children undergoing allogeneic HCT. METHODS From March 2015 through May 2016, 31 pediatric patients at 4 US children's hospitals were enrolled and had stool collected weekly from pre-HCT through 100 days post-HCT for infectious AGE pathogens by molecular testing. Demographics, clinical symptoms, antimicrobials, vaccination history, and outcomes were manually abstracted from the medical record into a standardized case report form. RESULTS We identified a pathogen in 18% (38/206) of samples, with many detections occurring during asymptomatic periods. Clostridioides difficile was the most commonly detected pathogen in 39% (15/38) of positive specimens, although only 20% (3/15) of C. difficile-positive specimens were obtained from children with diarrhea. Detection of sapovirus, in 21% (8/38) of pathogen-positive specimens, was commonly associated with AGE, with 87.5% of specimens obtained during symptomatic periods. Norovirus was not detected, and rotavirus was detected infrequently. Prolonged shedding of infectious pathogens was rare. CONCLUSIONS This multicenter, prospective, longitudinal study suggests that the epidemiology of AGE pathogens identified from allogeneic HCT patients may be changing. Previously reported viruses, such as rotavirus and norovirus, may be less common due to widespread vaccination and institution of infection control precautions, and emerging viruses such as sapoviruses may be increasingly recognized due to the use of molecular diagnostics.

Abstract
Human astroviruses (HAstVs) were first identified in 1975 and can be classified into three clades: classic HAstVs (HAstV 1-8), MLB (MLB1-3) and VA (VA1-5), with MLB and VA were newly identified. Recombination and a high mutation rate make HAstV as one of the rapidly evolving infectious agents. This study reported a novel identified recombinant human astrovirus (Y/1-CHN) and its long existence in two immunocompromised patients with diarrhea following allogeneic hematopoietic stem cell transplantation (allo-HSCT). The identified Yu/1-CHN genome contains 6801 base pairs encoding three open reading frames, with ORF1a best hit to the HAstV1 (Pune strain, 97 % nucleotide identity), while ORF1b and ORF2 best hit to HAstV-5 (DL30 strain, 99 % nucleotide identity). Possible recombination breakpoint was predicted to be located in the boundary of ORF1a and ORF1b. Different quasispecies were found in the host, and the dN/dS ratios of the S and P domains were determined to be 1.189 and 1.444, respectively, suggesting a positive selection existed. Fecal samples collected in different clinical phases from the two patients were all positive for Yu/1-CHN, suggesting a long existence of the virus in the host. It was indicated that immunocompromised patients may a reservoir for astrovirus, their excreta should be monitored even after discharge from hospital.

Infectious Norovirus Is Chronically Shed by Immunocompromised Pediatric Hosts. Viruses 2020; 12:v12060619.

Abstract
Noroviruses are a leading cause of gastroenteritis worldwide. Although infections in healthy individuals are self-resolving, immunocompromised individuals are at risk for chronic disease and severe complications. Chronic norovirus infections in immunocompromised hosts are often characterized by long-term virus shedding, but it is unclear whether this shed virus remains infectious. We investigated the prevalence, genetic heterogeneity, and temporal aspects of norovirus infections in 1140 patients treated during a 6-year period at a pediatric research hospital. Additionally, we identified 20 patients with chronic infections lasting 37 to >418 days. Using a new human norovirus in vitro assay, we confirmed the continuous shedding of infectious virus for the first time. Shedding lasted longer in male patients and those with diarrheal symptoms. Prolonged shedding of infectious norovirus in immunocompromised hosts can potentially increase the likelihood of transmission, highlighting the importance of isolation precautions to prevent nosocomial infections.

Infect Drug Resist 2019; 12:3893-3902. [PMID: 31908501 PMCID: PMC6925545 DOI: 10.2147/idr.s224291] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Accepted: 11/05/2019] [Indexed: 12/28/2022] Open
Abstract
Objective The analysis of epidemiology, risk factors and outcome of viral infections in children and adolescents after hematopoietic cell transplantation (HCT). Methods In this multicenter nationwide study a total of 971 HCT procedures (741 allo-HCT; 230 auto-HCT) over a period of 6 years were analyzed. Results During this period 801 episodes of viral infections were diagnosed in 442 patients. The incidence of viral infections was 57.9% in allo-HCT and 4.8% in auto-HCT patients. The most frequent infections after allo-HCT were caused by cytomegalovirus (CMV), polyoma BK virus (BKV) and Epstein-Barr virus (EBV). The majority of infections occurred within the first 4 months after allo-HCT and over 80% required pharmacotherapy or symptomatic therapy. The median time of treatment of specific viral infection ranged from 7 (for EBV) to 24 (for CMV) days. The highest mortality was observed in case of CMV infection. The risk factors for viral infections were allo-HCT, acute leukemia, acute and chronic graft versus host disease (a/cGVHD), and matched unrelated donor (MUD)/mismatched unrelated donor (MMUD)-HCT. The risk factor for death from viral infection were CMV-IgG seropositivity in acute lymphoblastic leukemia recipient, and MUD/MMUD-HCT. The incidence of EBV infection requiring pre-emptive treatment with rituximab in allo-HCT children was 19.3%. In 30.8% cases of EBV infection, these episodes were preceded by other viral infection and treated with antivirals, which did not prevent development of EBV-DNA-emia with need of rituximab treatment in 81.5% cases. In 47.7% of these cases, GVHD was a factor enabling development of significant EBV-DNA-emia during antiviral therapy of other infection. Conclusion We have shown that antiviral drugs do not prevent EBV reactivation in allo-HCT pediatric patients.

Abstract
We assessed the quasispecies heterogeneity of a human astrovirus MLB2 (HAstV-MLB2-YJMGK) in immunocompromised patients following hematopoietic stem cell transplantation and performed genetic and evolutionary analyses of HAstV isolates circulating worldwide. The result showed that the virus had diversified variants and a strong positive selection in the patient, indicating that such patients may be a reservoir for astrovirus. The time to the most recent common ancestor of MLB2 and classic HAstVs was around 1800 years, and it has a decline in effective population size of HAstVs in the late 100 years.

Abstract
OBJECTIVE Predictive factors associated with clinical outcomes of chronic norovirus infection (CNI) in primary immunodeficiency diseases (PIDD) are lacking. METHOD We sought to characterize CNI using a multi-institutional cohort of patients with PIDD and CNI using the Clinical Immunology Society's CIS-PIDD Listserv e-mail group. RESULTS Thirty-four subjects (21 males and 13 females) were reported from centers across North America, Europe, and Asia. All subjects were receiving high doses (median IgG dose: 1200 mg/kg/month) of supplemental immunoglobulin therapy. Fifty-three percent had a complete absence of B cells (median B-cell count 0; range 0-139 cells/μL). Common Variable Immune Deficiency (CVID) subjects manifested a unique phenotype with B-cell lymphopenia, non O+ blood type, and villous atrophy (logistic regression model, P = 0.01). Five subjects died, all of whom had no evidence of villous atrophy. CONCLUSION While Norovirus (NoV) is thought to replicate in B cells, in this PIDD cohort of CNI, B-cell lymphopenia was common, indicating that the presence of B lymphocytes is not essential for CNI.

Abstract
PURPOSE OF REVIEW The review summarizes the epidemiology, risk factors, clinical presentation, diagnosis and management of the most important etiologic agents of infectious diarrhea in critically ill transplant recipients. RECENT FINDINGS Diarrhea, frequently caused by infectious pathogens, can cause significant morbidity and mortality in transplant recipients. Diarrhea can lead to severe dehydration, acute renal failure, medication toxicity, rejection, graft-versus-host disease and impairs patients' quality of life. Opportunistic infectious pathogens can pose significant diagnostic and therapeutic challenges in immunocompromised hosts. SUMMARY In transplant recipients, it is vital to differentiate infectious from noninfectious diarrhea to adequately manage their therapeutic approach. Supportive measures and reduction in immunosuppression are essential for the treatment management.

Abstract
Norovirus causes an estimated 18% of all cases of acute gastroenteritis worldwide and is found to be associated with mortality. To create a first overview of severe complications and chronic sequelae of norovirus infections, a systematic review of literature was performed. Of 3928 individual hits, 176 publications remained for data extraction. Study periods varied between 1974 and 2017, though strongly skewed towards the last decade (n = 122, 70%). Countries of studies were worldwide, though Africa, and Carribean, Central and South America were underrepresented. Strong evidence was found for chronic diarrhea in immunocompromised patients, affecting 9%-100% of investigated cohorts. The duration of chronic diarrhea varied from four weeks up to nine years, leading to either wasting, weight loss or failure to thrive in a third of the reported cases (224). Other complications with significant evidence were necrotizing enterocolitis (NEC) in preterm infants associated with norovirus infection (8 papers), and benign infantile convulsions with gastroenteritis (BICG; 19 papers). Studies on norovirus infection and inflammatory bowel disease (IBD) mostly concluded against this association (5 of 7). The remaining papers mentioned a large variety of possible sequelae or complications. Based on the available literature, chronic norovirus diarrhea is the major sequela of norovirus infection in primary immune deficient, oncologic and transplant patients. Norovirus infection - like other gastrointestinal pathogens - can cause a range of sequelae and complications, and should be considered in the differential diagnosis of these manifestations.

Abstract
BACKGROUND Severe infections are among the most common causes of death in immunocompromised patients admitted to the intensive care unit. The epidemiology, diagnosis and treatment of these infections has evolved in the last decade. AIMS We aim to provide a comprehensive review of these severe infections in this population. SOURCES Review of the literature pertaining to severe infections in critically ill solid organ transplant recipients. PubMed and Embase databases were searched for documents published since database inception until November 2017. CONTENT The epidemiology of severe infections has changed in the immunocompromised patients. This population is presenting to the intensive care unit with specific transplantation procedure-related infections, device-associated infections, a multitude of opportunistic viral infections, an increasing number of nosocomial infections and bacterial diseases with a more limited therapeutic armamentarium. Both molecular diagnostics and imaging techniques have had substantial progress in the last decade, which will, we hope, translate into faster and more precise diagnoses, as well as more optimal empirical treatment de-escalation. IMPLICATIONS The key clinical elements to improve the outcome of critically ill solid organ transplant recipients depend on the knowledge of geographic epidemiology, specific surgical procedures, net state of immunosuppression, hospital microbial ecology, aggressive diagnostic strategy and search for source control, rapid initiation of antimicrobials and minimization of iatrogenic immunosuppression.

Abstract
BACKGROUND Norovirus (NV) can cause chronic and severe gastroenteritis with possible lethal outcome in immunocompromised patients. The knowledge of NV infections in allogeneic hematopoietic stem cell transplantation (HSCT) recipients is limited. The aim of this study was to clarify the clinical importance of NV in a large cohort of HSCT recipients. METHODS All patients undergoing HSCT and diagnosed with NV at Karolinska University Hospital from 2006-2012 were included in the study (63 patients). Clinical data were collected from medical records, and statistics were performed using the logistic regression method. RESULTS The majority of patients (70%) had short-term symptoms (≤14 days). However, 54% of all patients required admission or prolonged hospitalization owing to the infection. In 16% of the patients the symptoms were chronic (>30 days), and in all but one of these patients the clinical picture also was severe, with malnutrition requiring long-term TPN, or serious dehydration. Severe combined immune deficiency (SCID) diagnosis was associated with chronic symptoms of NV infection (OR 30.3, CI 2.5-368). CONCLUSION NV is an important pathogen in the HSCT setting, although the infection seems to be mild in most patients. Increased knowledge is needed to further identify risk factors for a severe course of NV infection in HSCT patients.

Abstract
The development of a new laboratory-developed norovirus assay provided an opportunity to assess testing patterns, incidence, and outcomes of norovirus among hematopoietic cell transplant (HCT) recipients. Clostridium difficile and norovirus tests from 1,393 HCT recipients were compared in these analyses. In this population of high-risk patients, norovirus appeared to occur seasonally, but testing was infrequent despite a correlation with more severe disease when compared with patients with C difficile infection.

Abstract
Norovirus is an emerging pathogen causing gastroenteritis. We sought to identify factors associated with clinical outcomes in a cohort of patients with laboratory-confirmed norovirus infection. We performed a retrospective chart review of patients with positive norovirus polymerase chain reaction in stool between October 1, 2015, and May 31, 2016. 128 unique patients were identified during the study period, 64 of whom had immune deficiency, of which only 3 patients had a primary immune deficiency (common variable immune deficiency), while 61 patients had a secondary immune deficiency. 50% of patients with immune deficiency were hospitalized as compared to only 30% of the non-immune-deficient cohort (odds ratio: 2.1 (1.1-4.18, P=0.04). One-third (32.8%) of the patients had a polymicrobial stool infection, and 21.1% had concurrent Clostridium difficile infection. Initial mean total leukocyte count was higher in the hospitalized group at 8.40×109/L versus 6.31×109/L in the nonhospitalized group (P=0.049). All 13 patients presenting with fever had symptomatic resolution (P=0.002). The presence of C. difficile infection was correlated with persistent symptoms (OR 2.30 [0.95-5.58], P=0.067). The overall mortality rate among our cohort was 3.13% (4 patients). All deceased patients had secondary immune deficiency, and none had C. difficile coinfection. Presence of an immune deficiency increases the risk of hospitalization with norovirus infection. Absence of fever is associated with lower resolution and possibly may contribute to a persistent infectious state. Presence of concomitant C. difficile infection is correlated with a lower overall mortality rate.

Abstract
Norovirus is a major cause of acute gastroenteritis worldwide and has emerged as an important issue of chronic infection in transplantation patients. Since no approved antiviral is available, we evaluated the effects of different immunosuppressants and ribavirin on norovirus and explored their mechanisms of action by using a human norovirus (HuNV) replicon-harboring model and a surrogate murine norovirus (MNV) infectious model. The roles of the corresponding drug targets were investigated by gain- or loss-of-function approaches. We found that the calcineurin inhibitors cyclosporine (CsA) and tacrolimus (FK506) moderately inhibited HuNV replication. Gene silencing of their cellular targets, cyclophilin A, FKBP12, and calcineurin, significantly inhibited HuNV replication. A low concentration, therapeutically speaking, of mycophenolic acid (MPA), an uncompetitive IMP dehydrogenase (IMPDH) inhibitor, potently and rapidly inhibited norovirus replication and ultimately cleared HuNV replicons without inducible resistance following long-term drug exposure. Knockdown of the MPA cellular targets IMPDH1 and IMPDH2 suppressed HuNV replication. Consistent with the nucleotide-synthesizing function of IMPDH, exogenous guanosine counteracted the antinorovirus effects of MPA. Furthermore, the competitive IMPDH inhibitor ribavirin efficiently inhibited norovirus and resulted in an additive effect when combined with immunosuppressants. The results from this study demonstrate that calcineurin phosphatase activity and IMPDH guanine synthase activity are crucial in sustaining norovirus infection; thus, they can be therapeutically targeted. Our results suggest that MPA shall be preferentially considered immunosuppressive medication for transplantation patients at risk of norovirus infection, whereas ribavirin represents as a potential antiviral for both immunocompromised and immunocompetent patients with norovirus gastroenteritis.

Abstract
In immunocompromised patients, the NoV infection is prolonged and severe. We retrospectively studied the severity of the NoV infection in children after an ITx, the treatment, and the long-term evolution. Norovirus PCR in stools was positive for 19 children in 21 separate episodes. The infection was symptomatic in 18 cases. At diagnosis, the median weight loss was 5% (0-11) and the creatinine clearance was 75 mL/min/1.73 m2 (19-142). On 14 digestive biopsies, the pathological findings were non-specific with a constant mononuclear infiltration, showing signs of rejection in one case. Fifteen children in 17 cases were hospitalized for a median duration of 41 days (0-119) with IV infusions for 33 days (0-120). The viral shedding lasted 78 days (20-360). Nine children with severe or prolonged diarrhea received intravenous IGs and four of them additional NTZ. On follow-up, five other children developed a rejection 12 months (1-33) after NoV infection. Four uncontrolled rejections led to graft removal. Children mostly needed hospital admission and IV rehydration, but the symptoms upon presentation were moderate. Symptoms and shedding durations are prolonged as expected. The treatment efficacy cannot be assessed. The rejection induction by the NoV cannot be excluded.

Abstract
In 2017, most intensive care units (ICUs) worldwide are admitting a growing population of immunosuppressed patients. The most common causes of pre-ICU immunosuppression are solid organ transplantation, hematopoietic stem cell transplantation, and infection due to human immunodeficiency virus. In this article, the authors review the most frequent infections that cause critical care illness in each of these 3 immunosuppressed patient populations.

Abstract
Chronic infection with norovirus is emerging as a significant risk for patients with immunodeficiency - either primary or secondary to therapeutic immunosuppression. Patients with primary immunodeficiency present a range of pathological responses to norovirus infection. Asymptomatic infections occur and differentiating viral carriage or prolonged viral shedding after self-limiting infection from infection causing protracted diarrhoea can be challenging, due to relatively mild pathological changes that may mimic other causes of diarrhoea in such patients (for instance pathogenic bacteria or parasites or graft-versus-host disease). However, a subset of patients with common variable immunodeficiency (CVID) experience a severe norovirus-associated enteropathy leading to intestinal villous atrophy and malabsorption. Symptomatic infection of up to 8 years has been demonstrated with clinical and histological recovery on viral clearance. Although oral immunoglobulins and nitazoxanide have been used to treat noroviral infections associated with immunosuppression, ribavirin is the only agent to date that has been linked to viral clearance in the Noroviral enteropathy associated with CVID.

Abstract
BACKGROUND No data are available on clinical manifestations and course of norovirus gastroenteritis (NVE) in intestinal allograft (from intestinal and multivisceral transplant recipients, ITR) compared to native intestine (from other allograft recipients, nITR). METHODS This was a retrospective study of solid organ transplant recipients with NVE at two centers from January 1, 2010 to April 1, 2014. Chi-square, t-test, linear and logistic regression analyses were done to compare NVE in ITR vs nITR patients. RESULTS The ITR (45 patients) were compared to nITR (107 patients). ITR were younger (odds ratio [OR]=0.90; P<.0001), less likely to receive anti-lymphocyte induction therapy (OR=0.15; P<.0001), and had shorter time from transplant to NVE (OR=0.99; P=.008). On presentation ITR had less frequent nausea (OR=0.11; P<.0001) or vomiting (OR=0.36; P=.01), higher white blood cell count (OR=1.09; P=.001), and higher glomerular filtration rate (OR=1.02; P<.0001). ITR were less likely to receive anti-motility agents (OR=9.6; P<.0001). ITR were more likely to stay longer on intravenous (IV) fluids (OR=1.18; P<.0001); have recurrent NVE (OR=4.25; P<.0001); have longer hospital stay (OR=1.07; P<.0001); develop acute rejection (OR=5.1; P=.006); and have lower overall survival (OR=0.28; P=.006). CONCLUSIONS Compared to nITR, the ITR with NVE were significantly younger, had less nausea and vomiting at presentation, received less anti-motility agents, required more IV fluids, and had longer hospital stay. A trend was seen for lower survival with NVE in ITR.

Abstract
BACKGROUND Norovirus (NV) infection has been reported as a cause of severe chronic diarrhea in transplant recipients, but this entity remains under-recognized in clinical practice, leading to diagnostic delays. Transplant clinicians should become familiar with this syndrome in order to facilitate early detection and management. METHODS Demographic, clinical, and outcomes variables were summarized from a series of transplant recipients with positive stool NV reverse transcription polymerase chain reaction (RT-PCR) assays at Johns Hopkins in 2013-2014. Factors associated with longer duration of symptoms were compared using random forest analysis. RESULTS Thirty-one of 193 (16%) transplant recipients who were tested for NV had positive stool RT-PCRs. Symptoms included diarrhea (100%), nausea/vomiting (58%), abdominal pain (52%), and wasting (35%). Acute kidney injury occurred in 23%, and persisted in 21% after 6 months. Median duration of diarrheal symptoms was 4 months (range, <1-20) and 11/31 (35.4%) patients had relapses after improvement. Wasting, incompatible kidney transplant status, and plasmapheresis were associated with longer diarrhea durations. Treatments included nitazoxanide (in 74%), reduction of immunosuppression (58%), and intravenous immunoglobulin (32%). Six patients died, but no deaths were attributed to NV. CONCLUSIONS It is important for clinicians to recognize that NV can cause severe chronic diarrhea in transplant recipients. In this series, receipt of a human leukocyte antigen- and/or blood type-incompatible kidney transplant, and plasmapheresis were associated with longer symptom duration.

Abstract
Noroviruses are among the most common cause of diarrhea in transplant recipients. The clinical spectrum of norovirus infection after transplant is increasingly being recognized. As substantial morbidity is now associated with norovirus infections in this population; the quest for rapid diagnostic modalities and newer therapies has expanded. Transplant recipients with norovirus infection are at risk for several complications, including protracted illness with malnutrition, organ failure, and chronic viral shedding. This review summarizes the current knowledge on the epidemiology, complications, diagnosis, and treatment of norovirus infection in the transplant setting.

Abstract
Immunocompromised patients such as those undergoing solid organ or hematopoietic stem cell transplantation are at substantial risk for infection with numerous pathogens. Infections with cytomegalovirus (CMV), herpes simplex virus (HSV), Epstein–Barr virus (EBV), and human herpesvirus-6 (HHV-6) are well-described complications of transplantation. As viruses previously believed to be quiescent through widespread vaccination (e.g., measles and mumps) reemerge and molecular diagnostic techniques are refined, rare and emerging viral infections are increasingly diagnosed in transplant recipients. This chapter will review the clinical manifestations, diagnosis, and potential antiviral therapies for these viruses in the transplant population.

Abstract
Viral gastroenteritis causing diarrhea is a common complication observed in lung transplant recipients. Differently from the mild and typically self-limited disease seen in immunocompetent subjects, immunocompromised patients frequently have a more severe course. Norovirus and rotavirus are among the leading causes of severe gastroenteritis in transplant recipients. Specific treatment is unavailable, although good supportive treatment can significantly reduce morbidity. Previous studies have suggested that oral immunoglobulins may be used for the treatment of acute viral gastroenteritis after solid-organ transplantation. Herein, we conducted a retrospective chart review of 12 lung transplant recipients with norovirus-induced gastroenteritis who were treated with oral immunoglobulins for 2 days. Eleven patients were successfully treated, whereas 1 subject was only mildly improved. Four patients had at least 1 recurrence. No significant adverse effects were observed. We conclude that oral immunoglobulins may be clinically useful for lung transplant recipients with norovirus-induced gastroenteritis.

Abstract
Case reports describe significant norovirus gastroenteritis morbidity in immunocompromised patients. We evaluated norovirus pathogenesis in prospectively enrolled solid organ (SOT) and hematopoietic stem cell transplant (HSCT) patients with diarrhea who presented to Texas Children's Hospital and submitted stool for enteric testing. Noroviruses were detected by real-time reverse transcription polymerase chain reaction. Clinical outcomes of norovirus diarrhea and non-norovirus diarrhea patients, matched by transplanted organ type, were compared. Norovirus infection was identified in 25 (22%) of 116 patients, more frequently than other enteropathogens. Fifty percent of norovirus patients experienced diarrhea lasting ≥14 days, with median duration of 12.5 days (range 1-324 days); 29% developed diarrhea recurrence. Fifty-five percent of norovirus patients were hospitalized for diarrhea, with 27% requiring intensive care unit (ICU) admission. One HSCT recipient developed pneumatosis intestinalis. Three HSCT patients expired ≤6 months of norovirus diarrhea onset. Compared to non-norovirus diarrhea patients, norovirus patients experienced significantly more frequent ICU admission (27% vs. 0%, p = 0.02), greater serum creatinine rise (median 0.3 vs. 0.2 mg/dL, p = 0.01), and more weight loss (median 1.6 vs. 0.6 kg, p < 0.01). Noroviruses are an important cause of diarrhea in pediatric transplant patients and are associated with significant clinical complications.

Abstract
BACKGROUND Adenoviremia adversely affects prognosis in the post-hematopoietic stem cell transplant setting. METHODS We sought to determine retrospectively the cutoff load of adenovirus in the stool as a predictor of adenoviremia, in children who underwent an allogeneic hematopoietic stem cell transplant. The prevalence of sapovirus, norovirus and astrovirus in the stool was also studied. RESULTS The study cohort consisted of 117 patients, of which 71 (60%) had diarrhea. Adenovirus was detected in the stool in 39 of 71 (55%) patients. Age ≤10 years (P = 0.05; odds ratio: 2.57; 95% confidence interval: 0.98-6.75) and male sex (P = 0.04; odds ratio: 2.67; 95% confidence interval: 1.02-6.99) increased risk for detection of adenovirus in stool on univariate analysis. Coinfections with enteric pathogens were infrequent. Viral load >10 copies/g stool predicted adenoviremia with a sensitivity and specificity of 82%. Sapovirus, norovirus and astrovirus were detected in 3, 4 and 1 patient, respectively. CONCLUSIONS Quantitative detection of adenovirus in stool may have implications for preemptive therapy. Testing for other enteric viruses may have implications for infection control.

Abstract
Norovirus gastroenteritis (NV-GE) is a highly transmittable disease that can lead to fatal outcomes in vulnerable populations including patients after hematopoietic stem cell transplantation (HSCT). Prompt detection of NV is therefore important for HSCT recipients. Immunochromatography (IC) can be used to easily and rapidly diagnose NV-GE by detecting NV antigens. In this study, we examined 642 stool specimens in patients who developed diarrhea after allogeneic HSCT between January 2007 and June 2011. NV was detected in 10 of 350 (2.9 %) HSCT recipients. The median onset of symptoms was 36 days (range 3-93) after HSCT. The median duration of symptoms was 42 days (3-135). A second or subsequent allogeneic HSCT was associated with a higher incidence of NV-GE (P = 0.034). Of four patients who underwent colonoscopy, two showed intestinal graft-versus-host disease (GVHD) histopathology, whereas the other two showed no evidence of GVHD, and thus no need for intensified immunosuppression. None of the patients died of NV-GE. In conclusion, IC may be useful in the differential diagnosis of diarrhea after allogeneic HSCT, and could enable the appropriate adjustment of immunosuppressive drugs and prompt preventive measures.

Abstract
Norovirus, an RNA virus of the family Caliciviridae, is a human enteric pathogen that causes substantial morbidity across both health care and community settings. Several factors enhance the transmissibility of norovirus, including the small inoculum required to produce infection (<100 viral particles), prolonged viral shedding, and its ability to survive in the environment. In this review, we describe the basic virology and immunology of noroviruses, the clinical disease resulting from infection and its diagnosis and management, as well as host and pathogen factors that complicate vaccine development. Additionally, we discuss overall epidemiology, infection control strategies, and global reporting efforts aimed at controlling this worldwide cause of acute gastroenteritis. Prompt implementation of infection control measures remains the mainstay of norovirus outbreak management.

Abstract
UNLABELLED Noroviruses are the leading cause of acute gastroenteritis outbreaks worldwide. The majority of norovirus outbreaks are caused by genogroup II.4 (GII.4). Novel GII.4 strains emerge every 2 to 4 years and replace older variants as the dominant norovirus. Novel variants emerge through a combination of recombination, genetic drift, and selection driven by population immunity, but the exact mechanism of how or where is not known. We detected two previously unknown novel GII.4 variants, termed GII.4 UNK1 and GII.4 UNK2, and a diverse norovirus population in fecal specimens from immunocompromised individuals with diarrhea after they had undergone bone marrow transplantation. We hypothesized that immunocompromised individuals can serve as reservoirs for novel norovirus variants. To test our hypothesis, metagenomic analysis of viral RNA populations was combined with a full-genome bioinformatic analysis of publicly available GII.4 norovirus sequences from 1974 to 2014 to identify converging sites. Variable sites were proportionally more likely to be within two amino acids (P < 0.05) of positively selected sites. Further analysis using a hypergeometric distribution indicated that polymorphic site distribution was random and its proximity to positively selected sites was dependent on the size of the norovirus genome and the number of positively selected sites.In conclusion, random mutations may have a positive impact on driving norovirus evolution, and immunocompromised individuals could serve as potential reservoirs for novel GII.4 strains. IMPORTANCE Norovirus is the most common cause of viral gastroenteritis in the United States. Every 2 to 3 years novel norovirus variants emerge and replace dominant strains. The continual emergence of novel noroviruses is believed to be caused by a combination of genetic drift, population immunity, and recombination, but exactly how this emergence occurs remains unknown. In this study, we identified two novel GII.4 variants in immunocompromised bone marrow transplant patients. Using metagenomic and bioinformatic analysis, we showed that most genetic polymorphisms in the novel variants occur near 0 to 2 amino acids of positively selected sites, but the distribution of mutations was random; clustering of polymorphisms with positively selected sites was a result of genome size and number of mutations and positively selected sites. This study shows that immunocompromised patients can harbor infectious novel norovirus variants, and although mutations in viruses are random, they can have a positive effect on viral evolution.

Abstract
BACKGROUND Human caliciviruses (Norovirus and Sapovirus) are important acute gastroenteritis agents. The Norovirus (NoV) disease is usually self-limited; however, prolonged viral excretion and complications have been reported, mainly in immunosuppressed individuals. OBJECTIVES In this prospective study, we have monitored allogeneic stem cell transplant (ASCT) patients for human calicivirus infection. STUDY DESIGN Ten ASCT patients were monitored for NoV and sapoviruses (SaV) infection, for a period of five months to a maximum of one year. Prolonged NoV excretion and long term viral RNA in the blood were assessed by multiplex RT-PCR targeting region C of the viral capsid. Secretor status of the patients was determined by enzyme immunoassay using Ulex Europaeus agglutinin. Partial genomic sequencing and phylogenetic analysis were performed to characterize the viral genotypes. RESULTS NoV was detected in six out of ten patients (60%). Prolonged viral excretion in feces (mean of 61.6 days) and long term presence of NoV RNA in the sera (mean of 33.6 days) of the patients were observed. SaV was not detected in any of the samples. All patients had diarrhea, vomiting and fever during NoV positivity. All NoV-positive samples were characterized as GI.3 NoV. Three Nov-infected patients presented with acute intestinal graft versus host disease. CONCLUSIONS This study brings important information on NoV course of infection in ASCT patients. It also provides evidence for long term viral RNA in the blood highlighting the importance of the inclusion of NoV screening in the routine testing performed before transplantation and during follow-up of these patients.

Abstract
Acute gastroenteritis caused by noroviruses often has a duration of 2-3 days and is characteristically self-limiting. In contrast, chronic infection caused by noroviruses in immunocompromised individuals can last from weeks to years, making clinical management difficult. The mechanisms by which noroviruses establish persistent infection, and the role of immunocompromised hosts as a reservoir for noroviruses in the general human population, are not known. However, study of this patient cohort may lead to new insights into norovirus biology and approaches to treatment.

Abstract
BACKGROUND Norovirus infection is increasingly recognized as an important cause of persistent gastroenteritis in immunocompromised hosts and can be a potential cause of morbidity in these populations. CASE PRESENTATION Here, we report a case of norovirus-related chronic diarrhea occurring in a 62-year-old immunocompromised patient treated with alemtuzumab for chronic lymphocytic leukemia. Despite different therapeutic strategies including tapering of immunosuppressive therapy and immunoglobulin administration, diarrhea unfortunately did not resolve and lasted for a total of more than twelve weeks with prolonged norovirus fecal excretion. CONCLUSIONS Norovirus infection can occur in the setting of alemtuzumab treatment, even as a single agent, and should be included in the differential diagnoses of acute and chronic diarrhea in these immunocompromised patients. Although the administration of oral immunoglobulin has been described as a promising efficient therapy, this was not the case in our patient. Clinical trials are thus clearly warranted to better define risk factors and efficient therapies for norovirus infection in immunocompromised populations.

Abstract
Noroviruses (NV) are the most common cause of acute gastrointestinal illness in the United States and worldwide. The development of specific antiviral countermeasures has lagged behind that of other viral pathogens, primarily because norovirus disease has been perceived as brief and self-limiting and robust assays suitable for drug discovery have been lacking. The increasing recognition that NV illness can be life-threatening, especially in immunocompromised patients who often require prolonged hospitalization and intensive supportive care, has stimulated new research to develop an effective antiviral therapy. Here, we propose a path forward for evaluating drug therapy in norovirus-infected immunocompromised individuals, a population at high risk for serious and prolonged illness. The clinical and laboratory features of norovirus illness in immunocompromised patients are reviewed, and potential markers of drug efficacy are defined. We discuss the potential design of clinical trials in these patients and how an antiviral therapy that proves effective in immunocompromised patients might also be used in the setting of acute outbreaks, especially in confined settings such as nursing homes, to block the spread of infection and reduce the severity of illness. We conclude by reviewing the current status of approved and experimental compounds that might be evaluated in a hospital setting.

Abstract
PURPOSE OF REVIEW Recipients of both solid organ transplant and hematopoietic stem cell transplantation are at increased risk for infectious morbidity and mortality after transplantation due to on-going immunosuppression. Gastrointestinal infections have been increasingly reported in these populations. RECENT FINDINGS Increased reports of gastrointestinal infections including bacterial infection with Clostridium difficile, viral infection with norovirus and parasitic pathogens like cryptosporidium are emerging. Risk factors identified have focused on type of transplant, transplant immunosuppression regimens and exposures. Although many events are self-limiting, significant morbidity and rare mortality are reported. SUMMARY Improved diagnostic techniques have increased the reporting of several gastrointestinal infections after transplantation, affording improved understanding of the epidemiology of these diseases. Armed with this emerging data, prevention, recognition of infection and treatment strategies can be more thoroughly assessed in these at-risk populations.

Abstract
Viral infections are important causes of morbidity and mortality after allogeneic stem cell hematopoietic transplantation (allo-HSCT). Although most viral infections present with asymptomatic or subclinical manifestations, viruses may result in fatal complications in severe immunocompromised recipients. Reactivation of latent viruses, such as herpesviruses, is frequent during the immunosuppression that occurs with allo-HSCT. Viruses acquired from community, such as the respiratory and gastrointestinal viruses, are also important pathogens of post-transplant viral diseases. Currently, molecular diagnostic methods have replaced or supplemented traditional methods, such as viral culture and antigen detection, in diagnosis of viral infections. The utilization of polymerase chain reaction facilitates the early diagnosis. In view of lacking efficacious agents for treatment of viral diseases, prevention of viral infections is extremely valuable. Application of prophylactic strategies including preemptive therapy reduces viral infections and diseases. Adoptive cellular therapy for restoring virus-specific immunity is a promising method in the treatment of viral diseases.

Microbiological diagnosis of severe diarrhea in kidney transplant recipients by use of multiplex PCR assays. J Clin Microbiol 2013; 51:1841-9.

Abstract
Diarrhea is a frequent complication after kidney transplantation, ascribed to adverse effects of the immunosuppressive therapy in case of negative microbiological examination of the stools. The aim of this study was to improve the microbiological diagnosis by implementing molecular tests. Fifty-four severe diarrhea events that occurred in 49 adult kidney transplant recipients from September 2010 to November 2011 were investigated. One or several enteric pathogens were detected in 13 (23%) stool samples using classical microbiological methods versus 39 (72%) for the seven commercially available multiplex PCR assays used retrospectively (P = 0.006). Interestingly, molecular diagnosis identified 15 multiple infections compared to none using classical techniques. The primary pathogens detected were enteropathogenic Escherichia coli (EPEC) (n = 15; 38%), Campylobacter spp. (n = 15; 38%), and Norovirus (n = 14; 36%). Specificities for Campylobacter and Norovirus infection diagnosis were 75 and 100%, respectively, by comparison to reference methods. Based on molecular findings, a cyclosporine-mycophenolate mofetil combination was identified as a risk factor for developing Norovirus-induced diarrhea. Norovirus infections were also responsible for higher weight loss than all the other causes of diarrhea. In samples from asymptomatic immunocompromised and immunocompetent patients, EPEC but not Norovirus and Campylobacter infections were detected at a frequency similar to that observed in symptomatic kidney transplant recipients. In conclusion, molecular tools significantly improved the detection of single and multiple enteric infections by comparison to classical techniques and could quickly become the key element in the management of severe acute diarrhea in transplant recipients.

Abstract
Norovirus (NoV) are the most common cause of acute gastroenteritidis in humans worldwide. They are transmitted through consumption of contaminated food, or mostly by direct person-to-person contact. However, susceptibility to NoV infection is variable. NoVs recognize carbohydrate ligand, including A, B, H and Lewis histoblood group antigen (HBGAs) for attachment to human epithelial cells. Synthesis of these HBGAs requires various glycosyltransferase encoded by the ABO, FUT2, FUT3 genes. The presence of distinct carbohydrates structures dependent upon the combined polymorphism at the FUT2, FUT3 and ABO loci influences susceptibility to NoV infection. NoV-glycan interactions studies show that different strains recognize specific HBGAs. Together with herd immunity, HBGAs play a major role in the epidemiology and evolution of NoVs.
