Item Open Access Breakthrough invasive fungal infections: Who is at risk?(Mycoses, 2020-10) Jenks, Jeffrey D; Cornely, Oliver A; Chen, Sharon C-A; Thompson, George R; Hoenigl, MartinThe epidemiology of invasive fungal infections (IFIs) in immunocompromised individuals has changed over the last few decades, partially due to the increased use of antifungal agents to prevent IFIs. Although this strategy has resulted in an overall reduction in IFIs, a subset of patients develop breakthrough IFIs with substantial morbidity and mortality in this population. Here, we review the most significant risk factors for breakthrough IFIs in haematology patients, solid organ transplant recipients, and patients in the intensive care unit, focusing particularly on host factors, and highlight areas that require future investigation.Item Open Access Bronchoalveolar lavage Aspergillus Galactomannan lateral flow assay versus Aspergillus-specific lateral flow device test for diagnosis of invasive pulmonary Aspergillosis in patients with hematological malignancies.(The Journal of infection, 2019-03) Jenks, Jeffrey D; Mehta, Sanjay R; Taplitz, Randy; Law, Nancy; Reed, Sharon L; Hoenigl, MartinItem Open Access Clinical characteristics and outcomes of invasive Lomentospora prolificans infections: Analysis of patients in the FungiScope® registry.(Mycoses, 2020-05) Jenks, Jeffrey D; Seidel, Danila; Cornely, Oliver A; Chen, Sharon; van Hal, Sebastiaan; Kauffman, Carol; Miceli, Marisa H; Heinemann, Melina; Christner, Martin; Jover Sáenz, Alfredo; Burchardt, Alexander; Kemmerling, Björn; Herbrecht, Raoul; Steinmann, Joerg; Shoham, Shmuel; Gräber, Sandra; Pagano, Livio; Deeren, Dries; Slavin, Monica A; Hoenigl, MartinOBJECTIVES:Invasive fungal infections caused by Lomentospora prolificans are associated with very high mortality rates and can be challenging to treat given pan-drug resistance to available antifungal agents. The objective of this study was to describe the clinical presentation and outcomes in a cohort of patients with invasive L prolificans infections. METHODS:We performed a retrospective review of medical records of patients with invasive L prolificans infection in the FungiScope® registry of rare invasive fungal infections. Patients diagnosed between 01 January 2008 and 09 September 2019 were included in for analysis. RESULTS:The analysis included 41 patients with invasive L prolificans infection from eight different countries. Haematological/oncological malignancies were the most frequent underlying disease (66%), disseminated infection was frequent (61%), and the lung was the most commonly involved organ (44%). Most infections (59%) were breakthrough infections. Progression/deterioration/treatment failure was observed in 23/40 (58%) of patients receiving antifungal therapy. In total, 21/41 (51%) patients, and 77% of patients with underlying haematological/oncological malignancy, had a fatal outcome attributed to invasive fungal infection. Combination antifungal therapy was frequent (24/40) and associated with improved survival. In particular, treatment regimens including terbinafine were significantly associated with higher treatment success at final assessment (P = .012), with a positive trend observed for treatment regimens that included voriconazole (P = .054). CONCLUSIONS:Lomentospora prolificans infections were associated with mortality rates of 77% and above in patients with underlying haematological/oncological malignancies and those with disseminated infections. While combination therapy is the preferred option for now, the hope lies with novel antifungals currently under development.Item Open Access Clinical effectiveness of posaconazole versus fluconazole as antifungal prophylaxis in hematology-oncology patients: a retrospective cohort study.(Cancer Med, 2014-06) Kung, Hsiang-Chi; Johnson, Melissa D; Drew, Richard H; Saha-Chaudhuri, Paramita; Perfect, John RIn preventing invasive fungal disease (IFD) in patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS), clinical trials demonstrated efficacy of posaconazole over fluconazole and itraconazole. However, effectiveness of posaconazole has not been investigated in the United States in real-world setting outside the environment of controlled clinical trial. We performed a single-center, retrospective cohort study of 130 evaluable patients ≥18 years of age admitted to Duke University Hospital between 2004 and 2010 who received either posaconazole or fluconazole as prophylaxis during first induction or first reinduction chemotherapy for AML or MDS. The primary endpoint was possible, probable, or definite breakthrough IFD. Baseline characteristics were well balanced between groups, except that posaconazole recipients received reinduction chemotherapy and cytarabine more frequently. IFD occurred in 17/65 (27.0%) in the fluconazole group and in 6/65 (9.2%) in the posaconazole group (P = 0.012). Definite/probable IFDs occurred in 7 (10.8%) and 0 patients (0%), respectively (P = 0.0013). In multivariate analysis, fluconazole prophylaxis and duration of neutropenia were predictors of IFD. Mortality was similar between groups. This study demonstrates superior effectiveness of posaconazole over fluconazole as prophylaxis of IFD in AML and MDS patients. Such superiority did not translate to reductions in 100-day all-cause mortality.Item Open Access Efficacy and safety of ex vivo cultured adult human mesenchymal stem cells (Prochymal™) in pediatric patients with severe refractory acute graft-versus-host disease in a compassionate use study.(Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2011-04) Prasad, Vinod K; Lucas, Kenneth G; Kleiner, Gary I; Talano, Julie An M; Jacobsohn, David; Broadwater, Gloria; Monroy, Rod; Kurtzberg, JoannePreliminary studies using directed-donor ex vivo expanded human mesenchymal stem cells (hMSCs) have shown promise in the treatment of acute graft-versus-host disease (aGVHD). However, their production is cumbersome and standardization is difficult. We describe the first experience of using a premanufactured, universal donor, formulation of hMSCs (Prochymal) in children (n = 12; 10 boys; 9 Caucasian; age range: 0.4-15 years) with treatment-resistant grade III and IV aGVHD who received therapy on compassionate use basis between July 2005 and June 2007 at 5 transplant centers. All patients had stage III or IV gut (GI) symptoms and half had additional liver and/or skin involvement. Disease was refractory to steroids in all cases and additionally to a median of 3 other immunosuppressive therapies. The hMSCs (8 × 10(6)cells/kg/dose in 2 patients and 2 × 10(6)cells/kg/dose in the rest) were infused intravenously over 1 hour twice a week for 4 weeks. Partial and mixed responders received subsequent weekly therapy for 4 weeks. HLA or other matching was not needed. The hMSCs were started at a median of 98 days (range: 45-237) posttransplant. A total of 124 doses were administered, with a median of 8 doses (range: 2-21) per patient. Overall, 7 (58%) patients had complete response, 2 (17%) partial response, and 3 (25%) mixed response. Complete resolution of GI symptoms occurred in 9 (75%) patients. Two patients relapsed after initial response and showed partial response to retreatment. The cumulative incidence of survival at 100 days from the initiation of Prochymal therapy was 58%. Five of 12 patients (42%) were still alive after a median follow-up of 611 days (range: 427-1111) in surviving patients. No infusional or other identifiable acute toxicity was seen in any patient. Multiple infusions of hMSCs were well tolerated and appeared to be safe in children. Clinical responses, particularly in the GI system, were seen in the majority of children with severe refractory aGVHD. Given the favorable results observed in a patient population with an otherwise grave prognosis, we conclude that hMSCs hold potential for the treatment of aGVHD, and should be further studied in phase III trials in pediatric and adult patients.Item Open Access One-unit versus two-unit cord-blood transplantation for hematologic cancers.(The New England journal of medicine, 2014-10) Wagner, John E; Eapen, Mary; Carter, Shelly; Wang, Yanli; Schultz, Kirk R; Wall, Donna A; Bunin, Nancy; Delaney, Colleen; Haut, Paul; Margolis, David; Peres, Edward; Verneris, Michael R; Walters, Mark; Horowitz, Mary M; Kurtzberg, Joanne; Blood and Marrow Transplant Clinical Trials NetworkBackground
Umbilical-cord blood has been used as the source of hematopoietic stem cells in an estimated 30,000 transplants. The limited number of hematopoietic cells in a single cord-blood unit prevents its use in recipients with larger body mass and results in delayed hematopoietic recovery and higher mortality. Therefore, we hypothesized that the greater numbers of hematopoietic cells in two units of cord blood would be associated with improved outcomes after transplantation.Methods
Between December 1, 2006, and February 24, 2012, a total of 224 patients 1 to 21 years of age with hematologic cancer were randomly assigned to undergo double-unit (111 patients) or single-unit (113 patients) cord-blood transplantation after a uniform myeloablative conditioning regimen and immunoprophylaxis for graft-versus-host disease (GVHD). The primary end point was 1-year overall survival.Results
Treatment groups were matched for age, sex, self-reported race (white vs. nonwhite), performance status, degree of donor-recipient HLA matching, and disease type and status at transplantation. The 1-year overall survival rate was 65% (95% confidence interval [CI], 56 to 74) and 73% (95% CI, 63 to 80) among recipients of double and single cord-blood units, respectively (P=0.17). Similar outcomes in the two groups were also observed with respect to the rates of disease-free survival, neutrophil recovery, transplantation-related death, relapse, infections, immunologic reconstitution, and grade II-IV acute GVHD. However, improved platelet recovery and lower incidences of grade III and IV acute and extensive chronic GVHD were observed among recipients of a single cord-blood unit.Conclusions
We found that among children and adolescents with hematologic cancer, survival rates were similar after single-unit and double-unit cord-blood transplantation; however, a single-unit cord-blood transplant was associated with better platelet recovery and a lower risk of GVHD.

Extension of allograft access to racial and ethnic minorities, rapid graft availability, flexibility of transplantation date, and low risks of disabling chronic graft-versus-host disease (GVHD) and relapse are significant advantages of CBT, and multiple series have reported a low risk of late transplantation-related mortality (TRM) post-transplantation. Nonetheless, early post-transplantation morbidity and TRM and the requirement for intensive early post-transplantation management have slowed the adoption of CBT. Targeted care strategies in CBT recipients can mitigate early transplantation complications and reduce transplantation costs. Herein we provide a practical "how to" guide to CBT for hematologic malignancies on behalf of the National Marrow Donor Program and the American Society of Blood and Marrow Transplantation's Cord Blood Special Interest Group. It shares the best practices of 6 experienced US transplantation centers with a special interest in the use of cord blood as a hematopoietic stem cell source. We address donor search and unit selection, unit thaw and infusion, conditioning regimens, immune suppression, management of GVHD, opportunistic infections, and other factors in supportive care appropriate for CBT. Meticulous attention to such details has improved CBT outcomes and will facilitate the success of CBT as a platform for future graft manipulations.Item Open Access Phase I/II Study of Stem-Cell Transplantation Using a Single Cord Blood Unit Expanded Ex Vivo With Nicotinamide.(Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2019-02) Horwitz, Mitchell E; Wease, Stephen; Blackwell, Beth; Valcarcel, David; Frassoni, Francesco; Boelens, Jaap Jan; Nierkens, Stefan; Jagasia, Madan; Wagner, John E; Kuball, Jurgen; Koh, Liang Piu; Majhail, Navneet S; Stiff, Patrick J; Hanna, Rabi; Hwang, William YK; Kurtzberg, Joanne; Cilloni, Daniela; Freedman, Laurence S; Montesinos, Pau; Sanz, GuillermoPurpose
Increasing the number of hematopoietic stem and progenitor cells within an umbilical cord blood (UCB) graft shortens the time to hematopoietic recovery after UCB transplantation. In this study, we assessed the safety and efficacy of a UCB graft that was expanded ex vivo in the presence of nicotinamide and transplanted after myeloablative conditioning as a stand-alone hematopoietic stem-cell graft.Methods
Thirty-six patients with hematologic malignancies underwent transplantation at 11 sites.Results
The cumulative incidence of neutrophil engraftment at day 42 was 94%. Two patients experienced secondary graft failure attributable to viral infections. Hematopoietic recovery was compared with that observed in recipients of standard UCB transplantation as reported to the Center for International Blood and Marrow Transplant Research (n = 146). The median time to neutrophil recovery was 11.5 days (95% CI, 9 to 14 days) for recipients of nicotinamide-expanded UCB and 21 days (95% CI, 20 to 23 days) for the comparator ( P < .001). The median time to platelet recovery was 34 days (95% CI, 32 to 42 days) and 46 days (95% CI, 42 to 50 days) for the expanded and the comparator cohorts, respectively ( P < .001). The cumulative incidence of grade 2 to 4 acute graft-versus-host disease (GVHD) at day 100 was 44%, and grade 3 and 4 acute GVHD at day 100 was 11%. The cumulative incidence at 2 years of all chronic GVHD was 40%, and moderate/severe chronic GVHD was 10%. The 2-year cumulative incidences of nonrelapse mortality and relapse were 24% and 33%, respectively. The 2-year probabilities of overall and disease-free survival were 51% and 43%, respectively.Conclusion
UCB expanded ex vivo with nicotinamide shortens median neutrophil recovery by 9.5 days (95% CI, 7 to 12 days) and median platelet recovery by 12 days (95% CI, 3 to 16.5 days). This trial establishes feasibility, safety, and efficacy of an ex vivo expanded UCB unit as a stand-alone graft.Item Open Access Plerixafor (a CXCR4 antagonist) following myeloablative allogeneic hematopoietic stem cell transplantation enhances hematopoietic recovery.(J Hematol Oncol, 2018-03-04) Green, Michael MB; Chao, Nelson; Chhabra, Saurabh; Corbet, Kelly; Gasparetto, Cristina; Horwitz, Ari; Li, Zhiguo; Venkata, Jagadish Kummetha; Long, Gwynn; Mims, Alice; Rizzieri, David; Sarantopoulos, Stefanie; Stuart, Robert; Sung, Anthony D; Sullivan, Keith M; Costa, Luciano; Horwitz, Mitchell; Kang, YubinBACKGROUND: The binding of CXCR4 with its ligand (stromal-derived factor-1) maintains hematopoietic stem/progenitor cells (HSPCs) in a quiescent state. We hypothesized that blocking CXCR4/SDF-1 interaction after hematopoietic stem cell transplantation (HSCT) promotes hematopoiesis by inducing HSC proliferation. METHODS: We conducted a phase I/II trial of plerixafor on hematopoietic cell recovery following myeloablative allogeneic HSCT. Patients with hematologic malignancies receiving myeloablative conditioning were enrolled. Plerixafor 240 μg/kg was administered subcutaneously every other day beginning day +2 until day +21 or until neutrophil recovery. The primary efficacy endpoints of the study were time to absolute neutrophil count >500/μl and platelet count >20,000/μl. The cumulative incidence of neutrophil and platelet engraftment of the study cohort was compared to that of a cohort of 95 allogeneic peripheral blood stem cell transplant recipients treated during the same period of time and who received similar conditioning and graft-versus-host disease prophylaxis. RESULTS: Thirty patients received plerixafor following peripheral blood stem cell (n = 28) (PBSC) or bone marrow (n = 2) transplantation. Adverse events attributable to plerixafor were mild and indistinguishable from effects of conditioning. The kinetics of neutrophil and platelet engraftment, as demonstrated by cumulative incidence, from the 28 study subjects receiving PBSC showed faster neutrophil (p = 0.04) and platelet recovery >20 K (p = 0.04) compared to the controls. CONCLUSIONS: Our study demonstrated that plerixafor can be given safely following myeloablative HSCT. It provides proof of principle that blocking CXCR4 after HSCT enhances hematopoietic recovery. Larger, confirmatory studies in other settings are warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT01280955.Item Open Access Pre-engraftment syndrome after myeloablative dual umbilical cord blood transplantation: risk factors and response to treatment.(Bone marrow transplantation, 2013-07) Kanda, J; Kaynar, L; Kanda, Y; Prasad, VK; Parikh, SH; Lan, L; Shen, T; Rizzieri, DA; Long, GD; Sullivan, KM; Gasparetto, C; Chute, JP; Morris, A; Winkel, S; McPherson, J; Kurtzberg, J; Chao, NJ; Horwitz, MEHigh fevers and/or rashes prior to neutrophil engraftment are frequently observed after umbilical cord blood (UCB) transplantation, and the condition is referred to as pre-engraftment syndrome (PES). Few studies have evaluated the risk factors for and treatment response to PES. Therefore, we retrospectively characterized PES in 57 consecutive engrafted patients (≥ 12 years old) who received myeloablative dual UCB transplantation. All patients received TBI (≥ 13.2 Gy)-based myeloablative conditioning. Tacrolimus (n=35) or CYA (n=22) combined with mycophenolate mofetil was used as GVHD prophylaxis. PES was defined as the presence of non-infectious fever (≥ 38.5 °C) and/or rash prior to or on the day of neutrophil engraftment. The incidence (95% confidence interval) of PES was 77% (66-88%). The incidence of PES was significantly higher in patients who received CYA as a GVHD prophylaxis than those who received tacrolimus (P<0.001), and this association was confirmed in the multivariate analysis. The occurrence of PES did not impact OS or tumor relapse, although it may have increased non-relapse mortality (P=0.071). The incidence of acute GHVD or treatment-related mortality was not influenced by the choice to use corticosteroids to treat PES. This study suggests that use of CYA for GVHD prophylaxis increases the risk of PES following dual UCB transplantation.Item Open Access Prevalence and Etiology of Community-acquired Pneumonia in Immunocompromised Patients.(Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2019-04) Di Pasquale, Marta Francesca; Sotgiu, Giovanni; Gramegna, Andrea; Gramegna, Andrea; Radovanovic, Dejan; Terraneo, Silvia; Reyes, Luis F; Rupp, Jan; González Del Castillo, Juan; Blasi, Francesco; Aliberti, Stefano; Restrepo, Marcos I; GLIMP InvestigatorsBackground
The correct management of immunocompromised patients with pneumonia is debated. We evaluated the prevalence, risk factors, and characteristics of immunocompromised patients coming from the community with pneumonia.Methods
We conducted a secondary analysis of an international, multicenter study enrolling adult patients coming from the community with pneumonia and hospitalized in 222 hospitals in 54 countries worldwide. Risk factors for immunocompromise included AIDS, aplastic anemia, asplenia, hematological cancer, chemotherapy, neutropenia, biological drug use, lung transplantation, chronic steroid use, and solid tumor.Results
At least 1 risk factor for immunocompromise was recorded in 18% of the 3702 patients enrolled. The prevalences of risk factors significantly differed across continents and countries, with chronic steroid use (45%), hematological cancer (25%), and chemotherapy (22%) the most common. Among immunocompromised patients, community-acquired pneumonia (CAP) pathogens were the most frequently identified, and prevalences did not differ from those in immunocompetent patients. Risk factors for immunocompromise were independently associated with neither Pseudomonas aeruginosa nor non-community-acquired bacteria. Specific risk factors were independently associated with fungal infections (odds ratio for AIDS and hematological cancer, 15.10 and 4.65, respectively; both P = .001), mycobacterial infections (AIDS; P = .006), and viral infections other than influenza (hematological cancer, 5.49; P < .001).Conclusions
Our findings could be considered by clinicians in prescribing empiric antibiotic therapy for CAP in immunocompromised patients. Patients with AIDS and hematological cancer admitted with CAP may have higher prevalences of fungi, mycobacteria, and noninfluenza viruses.Item Open Access Randomized, double-blind trial of fluconazole versus voriconazole for prevention of invasive fungal infection after allogeneic hematopoietic cell transplantation.(Blood, 2010-12) Wingard, John R; Carter, Shelly L; Walsh, Thomas J; Kurtzberg, Joanne; Small, Trudy N; Baden, Lindsey R; Gersten, Iris D; Mendizabal, Adam M; Leather, Helen L; Confer, Dennis L; Maziarz, Richard T; Stadtmauer, Edward A; Bolaños-Meade, Javier; Brown, Janice; Dipersio, John F; Boeckh, Michael; Marr, Kieren A; Blood and Marrow Transplant Clinical Trials NetworkInvasive fungal infection (IFI) is a serious threat after allogeneic hematopoietic cell transplant (HCT). This multicenter, randomized, double-blind trial compared fluconazole (N = 295) versus voriconazole (N = 305) for the prevention of IFI in the context of a structured fungal screening program. Patients undergoing myeloablative allogeneic HCT were randomized before HCT to receive study drugs for 100 days, or for 180 days in higher-risk patients. Serum galactomannan was assayed twice weekly for 60 days, then at least weekly until day 100. Positive galactomannan or suggestive signs triggered mandatory evaluation for IFI. The primary endpoint was freedom from IFI or death (fungal-free survival; FFS) at 180 days. Despite trends to fewer IFIs (7.3% vs 11.2%; P = .12), Aspergillus infections (9 vs 17; P = .09), and less frequent empiric antifungal therapy (24.1% vs 30.2%, P = .11) with voriconazole, FFS rates (75% vs 78%; P = .49) at 180 days were similar with fluconazole and voriconazole, respectively. Relapse-free and overall survival and the incidence of severe adverse events were also similar. This study demonstrates that in the context of intensive monitoring and structured empiric antifungal therapy, 6-month FFS and overall survival did not differ in allogeneic HCT recipients given prophylactic fluconazole or voriconazole. This trial was registered at www.clinicaltrials.gov as NCT00075803.Item Open Access Umbilical cord blood expansion with nicotinamide provides long-term multilineage engraftment.(The Journal of clinical investigation, 2014-07) Horwitz, Mitchell E; Chao, Nelson J; Rizzieri, David A; Long, Gwynn D; Sullivan, Keith M; Gasparetto, Cristina; Chute, John P; Morris, Ashley; McDonald, Carolyn; Waters-Pick, Barbara; Stiff, Patrick; Wease, Steven; Peled, Amnon; Snyder, David; Cohen, Einat Galamidi; Shoham, Hadas; Landau, Efrat; Friend, Etty; Peleg, Iddo; Aschengrau, Dorit; Yackoubov, Dima; Kurtzberg, Joanne; Peled, TonyBackground
Delayed hematopoietic recovery is a major drawback of umbilical cord blood (UCB) transplantation. Transplantation of ex vivo-expanded UCB shortens time to hematopoietic recovery, but long-term, robust engraftment by the expanded unit has yet to be demonstrated. We tested the hypothesis that a UCB-derived cell product consisting of stem cells expanded for 21 days in the presence of nicotinamide and a noncultured T cell fraction (NiCord) can accelerate hematopoietic recovery and provide long-term engraftment.Methods
In a phase I trial, 11 adults with hematologic malignancies received myeloablative bone marrow conditioning followed by transplantation with NiCord and a second unmanipulated UCB unit. Safety, hematopoietic recovery, and donor engraftment were assessed and compared with historical controls.Results
No adverse events were attributable to the infusion of NiCord. Complete or partial neutrophil and T cell engraftment derived from NiCord was observed in 8 patients, and NiCord engraftment remained stable in all patients, with a median follow-up of 21 months. Two patients achieved long-term engraftment with the unmanipulated unit. Patients transplanted with NiCord achieved earlier median neutrophil recovery (13 vs. 25 days, P < 0.001) compared with that seen in historical controls. The 1-year overall and progression-free survival rates were 82% and 73%, respectively.Conclusion
UCB-derived hematopoietic stem and progenitor cells expanded in the presence of nicotinamide and transplanted with a T cell-containing fraction contain both short-term and long-term repopulating cells. The results justify further study of NiCord transplantation as a single UCB graft. If long-term safety is confirmed, NiCord has the potential to broaden accessibility and reduce the toxicity of UCB transplantation.Trial registration

Gamida Cell Ltd.Item Open Access Unlicensed Umbilical Cord Blood Units Provide a Safe and Effective Graft Source for a Diverse Population: A Study of 2456 Umbilical Cord Blood Recipients.(Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2020-04) Ballen, Karen; Logan, Brent R; Chitphakdithai, Pintip; Kuxhausen, Michelle; Spellman, Stephen R; Adams, Alexia; Drexler, Rebecca J; Duffy, Merry; Kemp, Ann; King, Roberta; Babic, Aleksandar; Delaney, Colleen; Karanes, Chatchada; Kurtzberg, Joanne; Petz, Lawrence; Scaradavou, Andromachi; Shpall, Elizabeth J; Smith, Clayton; Confer, Dennis L; Miller, John PUmbilical cord blood (UCB) transplantation (UCBT) is a curative procedure for patients with hematologic malignancies and genetic disorders and expands access to transplantation for non-Caucasian patients unable to find a fully matched unrelated donor. In 2011, the US Food and Drug Administration required that unrelated UCBT be performed using either licensed UCB or unlicensed UCB under the Investigational New Drug (IND) program. The National Marrow Donor Program manages an IND under which 2456 patients (1499 adults and 957 children, 564 with malignant diseases and 393 with nonmalignant diseases) underwent single or double UCBT between October 2011 and December 2016. The median patient age was 31 years (range, <1 to 81 years), and 50% of children and 36% of adults were non-Caucasian. The median time to neutrophil engraftment (ie, absolute neutrophil count ≥500/mm3) was 22 days for adults, 20 days for pediatric patients with malignant diseases, and 19 days for pediatric patients with nonmalignant diseases, with corresponding rates of engraftment at 42 days of 89%, 88%, and 90%. In these 3 groups of patients, the incidence of acute graft-versus-host disease (GVHD) grade II-IV was 35%, 32%, and 24%; the incidence of chronic GVHD was 24%, 26%, and 24%; and 1-year overall survival (OS) was 57%, 71%, and 79%, respectively. In multivariate analysis, younger age, lower Hematopoietic Cell Transplantation-Specific Comorbidity Index, early-stage chemotherapy-sensitive disease, and higher performance score were predictive of improved OS for adults. In a subset analysis of children with malignancies undergoing single UCBT, the use of either licensed UCB (n = 48) or unlicensed UCB (n = 382) was associated with similar engraftment and survival. The use of unlicensed UCB units is safe and effective and provides an important graft source for a diverse population.Item Open Access Using Interleukin 6 and 8 in Blood and Bronchoalveolar Lavage Fluid to Predict Survival in Hematological Malignancy Patients With Suspected Pulmonary Mold Infection.(Frontiers in immunology, 2019-01) Rawlings, Stephen A; Heldt, Sven; Prattes, Juergen; Eigl, Susanne; Jenks, Jeffrey D; Flick, Holger; Rabensteiner, Jasmin; Prüller, Florian; Wölfler, Albert; Neumeister, Peter; Strohmaier, Heimo; Krause, Robert; Hoenigl, MartinBackground: Molds and other pathogens induce elevated levels of several cytokines, including interleukin (IL)-6 and IL-8. The objective of this study was to investigate the prognostic value of IL-6 and IL-8 as well as fungal biomarkers in blood and bronchoalveolar lavage fluid (BAL) for overall survival in patients with underlying hematological malignancies and suspected mold infection. Methods: This cohort study included 106 prospectively enrolled adult cases undergoing bronchoscopy. Blood samples were collected within 24 h of BAL sampling and, in a subset of 62 patients, serial blood samples were collected up until 4 days after bronchoscopy. IL-6, IL-8, and other cytokines as well as galactomannan (GM) and β-D-glucan (BDG) were assayed in blood and BAL fluid and associations with overall mortality were assessed at the end of the study using receiver operating characteristic (ROC) curve analysis. Results: Both blood IL-8 (AUC 0.731) and blood IL-6 (AUC 0.699) as well as BAL IL-6 (AUC 0.763) and BAL IL-8 (AUC 0.700) levels at the time of bronchoscopy were predictors of 30-day all-cause mortality. Increasing blood IL-6 levels between bronchoscopy and day four after bronchoscopy were significantly associated with higher 90-day mortality, with similar findings for increasing IL-8 levels. In ROC analysis the difference of blood IL-8 levels between 4 days after bronchoscopy and the day of bronchoscopy had an AUC of 0.829 (95%CI 0.71-0.95; p < 0.001) for predicting 90-day mortality. Conclusions: Elevated levels of IL-6 and IL-8 in blood or BAL fluid at the time of bronchoscopy, and rising levels in blood 4 days following bronchoscopy were predictive of mortality in these patients with underlying hematological malignancy who underwent bronchoscopy for suspected mold infection.
