    Economic analysis of antenatal screening for human T-cell lymphotropic virus type 1 in Brazil: an open access cost-utility model
    (2023) ROSADAS, Carolina; SENNA, Katia; COSTA, Milene da; ASSONE, Tatiane; CASSEB, Jorge; NUKUI, Youko; COOK, Lucy; MARIANO, Livia; CASTRO, Bernardo Galvao; GRASSI, Maria Fernanda Rios; OLIVEIRA, Augusto Cesar Penalva de; CATERINO-DE-ARAUJO, Adele; MALIK, Bassit; BOA-SORTE, Ney; PEIXOTO, Paula; PUCCIONI-SOHLER, Marzia; SANTOS, Marisa; TAYLOR, Graham Philip
    Background Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus that causes severe diseases, such as aggressive cancer or progressive neurological disease. HTLV-1 affects mainly people in areas with low human development index and can be transmitted from mother to child, primarily through breastfeeding. Refraining from breastfeeding is an effective intervention to reduce the risk of infection in infants. However, HTLV-1 antenatal screening is not offered globally. According to WHO, the scarcity of cost-effectiveness studies is considered one of the major barriers to the implementation of policies to prevent HTLV-1 infection. Therefore, this study aimed to assess the cost-effectiveness of antenatal screening and postnatal interventions to prevent HTLV-1 mother-to-child transmission in Brazil and to develop an open-access, editable, mathematical model that can be used by other countries and regions to assess different scenarios. Methods In this cost-utility analysis, we constructed a decision tree and a Markov model to assess the cost-effectiveness of HTLV-1 antenatal screening and postnatal interventions (ie, avoidance of breastfeeding, by suppression of lactation with cabergoline, and provision of formula feed) to reduce transmission. For our model, we used data from Brazil and we took the perspective of the public health-care system to estimate costs. Findings The implementation of both screening and interventions would result in the prevention of 1039 infections in infants every year in Brazil with an incremental cost-effectiveness ratio (ICER) of US$11 415 per quality-adjusted lifeyear (QALY). 88% of all probabilistic sensitivity analysis simulations had ICER values lower than the Brazilian costeffectiveness threshold ($18 107 center dot 74 per QALY). HTLV-1 prevalence in pregnant women, the risk of HTLV-1 transmission when breastfeeding lasts for 6 months or more, and the cost of screening tests were the variables with the largest effect on ICER. Interpretation HTLV-1 antenatal screening is cost-effective in Brazil. An open-access model was developed, and this tool could be used to assess the cost-effectiveness of such policy globally, favouring the implementation of interventions to prevent HTLV-1 mother-to-child transmission worldwide.

    Impact of Discontinuing Levofloxacin Prophylaxis on Bloodstream Infections in Neutropenic Hematopoietic Stem Cell Transplantation Patients
    (2022) GUIMARAES, Thais; BORGES, Igor Carmo; SPADAO, Fernanda de Souza; MARIANO, Livia; NASCIMENTO, Marina de Mattos; HIGASHINO, Hermes; ROSSI, Flavia; ROCHA, Vanderson; COSTA, Silvia Figueiredo
    Multidrug-resistant pathogens have emerged worldwide. We have driven the hypothesis that the non-use of fluoroquinolone prophylaxis during neutropenia could reduce antibiotic resistance in Gram-negative bacteria that cause bloodstream infections (BSIs) in hematopoietic stem cell transplantation (HSCT) patients and that this change in resistance pattern could lead to an impact on BSI mortality. This is a quasi-experimental study comparing BSI incidence, resistance patterns of bacteria that cause BSI, and BSI mortality when levofloxacin prophylaxis was routine for neutropenic HSCT patients (2016-2018) to when fluoroquinolone prophylaxis was discontinued in our center (2019). Bivariate comparisons and multivariate logistic regression models were used for analyses. A total of 310 HSCTs (66 (21%) allogeneic and 244 (79%) autologous) were performed during the study period. Sixty (19%) patients had BSIs, 30 in each evaluated period. The discontinuation of levofloxacin prophylaxis was associated with an increase in BSI incidence and a decrease in the resistance rates of causative BSI bacteria and in BSI 30-day mortality. The increase in the rate of resistant bacteria causing BSI and in BSI mortality might outweigh the benefits of a decrease in BSI incidence caused by fluoroquinolone prophylaxis in neutropenic HSCT patients. We suggest that the routine use of fluoroquinolone in this context be revisited.

    Prevalence of latent Mycobacterium tuberculosis infection in hematopoietic stem cell transplantation comparing tuberculin skin test and interferon-gamma release assay
    (2023) CASTRO-LIMA, Victor A. C.; SANTOS, Ana Paula T.; MUSQUEIRA, Priscila T.; MALUF, Natalya Z.; RAMOS, Jessica F.; MARIANO, Livia; ROCHA, Vanderson; COSTA, Silvia F.
    The aim of this study was to evaluate the prevalence of latent Mycobacterium tuberculosis infection in hematopoietic stem cell transplantation candidates, using tuberculin skin test and QuantiFERON-TB Gold-Plus, in a high-burden tuberculosis country. Adult candidates for hematopoietic stem cell transplantation performed both tests before and those submitted to transplantation were followed up for 12 months. The prevalence of latent Mycobacterium tuberculosis infection was 17.1% and a moderate agreement between QuantiFERON-TB Gold-Plus and tuberculin skin test was observed in this population. Previous tuberculosis exposure was a risk factor for latent Mycobacterium tuberculosis infection. No cases of tuberculosis were diagnosed during follow-up period.

    In the COVID-19 scenario, patients undergoing hematopoietic stem cell transplantation (HSCT) infected with SARS-CoV-2 may have an increased risk of death. Through a national multicenter study, we aimed to describe the impact of COVID-19 on the survival of HSCT recipients in Brazil. Eighty-six patients with a confirmed diagnosis of SARS-CoV-2 (92% by RT-PCR) were included. There were 24 children and 62 adults receiving an autologous (n = 25) and allogeneic (n = 61) HSCT for malignant (n = 72) and non-malignant (n = 14) disorders. Twenty-six patients died, (10 on autologous (38%) and 16 patients (62%) on allogeneic group). The estimated overall survival (OS) at day 40 was 69%. Adults had decreased OS compared to children (66% vs 79%, p = 0.03). The severity of symptoms at the time of diagnosis, ECOG score, laboratory tests (C-reactive protein, urea values) were higher in patients who died (p < 0.05). In conclusion, HSCT recipients infected with SARS-CoV-2 have a high mortality rate mainly in adults and patients with critical initial COVID-19 presentation. These findings show the fragility of HSCT recipients with SARS-CoV-2 infection. Therefore, the importance of adherence to preventive measures is evident, in addition to prioritizing the vaccination of family members and the HSCT team.

    Chronic graft-versus-host-disease treatment in Brazil: analyses of failure-free survival
    (2023) VIGORITO, Afonso Celso; MIRANDA, Eliana Cristina Martins; COLTURATO, Vergilio Antonio Rensi; FUNKE, Vaneuza Araujo Moreira; FATOBENE, Giancarlo; MARIANO, Livia; MACEDO, Maria Cristina Martins de Almeida; RIBEIRO, Lorena Bedotti; DAUDT, Liane Esteves; MOREIRA, Maria Claudia Rodrigues; BONFIM, Carmem; COLELLA, Marcos Paulo; SEBER, Adriana; RODRIGUES, Morgani; DUARTE, Fernando Barroso; MARTIN, Paul J.; FLOWERS, Mary E. D.
    Failure-free survival (FFS), defined as the absence of new systemic treatment, recurrence of original malignancy and mortality not associated with recurrence after allogeneic hematopoietic stem cell transplantation (HCT), is a robust clinical measure to interpret results of initial systemic treatment of chronic graft-versus-host disease (cGVHD). We evaluate FFS after initial treatment of cGVHD in a mixed-race cohort from a resource-constrained country. This retrospective study included 354 consecutive patients after their first HCT between January 2014 and August 2020, who received initial systemic treatment for moderate or severe cGVHD at 13 Brazilian centers. Cox regression models were used to identify risk factors for treatment failure. The overall median follow-up among survivors was 28 months (range 1-71) after initial treatment. FFS was 89% at 6 months, 71% at 1 year and 52% at 2 years. New systemic treatment was the major cause of failure. In multivariable models, prior grades II-IV acute GVHD, a National Institutes of Health severity score of 3 in liver, gastrointestinal tract or lung involvement, and onset of initial treatment of cGVHD within 12 months after transplantation were all associated with an increased risk of treatment failure. Our results could serve as a benchmark for the design of future clinical trials evaluating initial treatment of cGVHD in resource-constrained locations.

    Impact of allele-level HLA matching on outcomes after double cord blood transplantation in adults with malignancies
    (2023) FATOBENE, Giancarlo; MARIANO, Livia; VOLT, Fernanda; MOREIRA, Frederico; CONELISSEN, Jan; FURST, Sabine; DAGUINDAU, Etienne; SIRVENT, Anne; LATOUR, Regis Peffault de; RAFIL, Hanadi; RIVERA-FRANCO, Monica M.; KENZEY, Chantal; SCIGLIUOLO, Graziana Maria; CAPPELLI, Barbara; RUGGERI, Annalisa; GLUCKMAN, Eliane; ROCHA, Vanderson
    In single unrelated cord blood transplantation (UCBT), an increasing number of HLA allele mismatches (MM) has been associated with inferior overall survival (OS) and attributed to higher transplant-related mortality (TRM). Previous studies on the role of allele-level HLA matching after double UCBT (dUCBT) showed conflicting results. In this study, we report the impact of allele-level HLA matching on the outcomes of a large dUCBT cohort. We included 963 adults with hematologic malignancies, with available allele-level HLA matching at HLAA, -B, -C, and -DRB1, receiving dUCBT between 2006 to 2019. Assignment of donor-recipient HLA match was performed considering the unit with the highest disparity with the recipient. Three hundred ninety-two patients received dUCBT with 0 to 3 MM and 571 with >4 allele MM. For recipients of dUCBT with 0 to 3 MM, day-100 and 4-year TRM were 10% and 23%, respectively, compared with 16% and 36% for those with >4 MM. A higher degree of allele MM was also associated with the worse neutrophil recovery and lower incidence of relapse; no significant effect on graft-versus-host disease was observed. Patients receiving units with 0 to 3 MM had a 4-year OS of 54% compared with 43% for those receiving units with >4 MM. The inferior OS associated with higher HLA disparity was only partially mitigated by increased total nucleated cell doses. Our results confirm that allele-level HLA typing is a significant factor for OS after dUCBT, and units with >4 MM (<4/8 HLA-matched) should be avoided if possible.

    Assessment by Extended-Coverage Next-Generation Sequencing Typing of DPA1 and DPB1 Mismatches in Siblings Matching at HLA-A, -B, -C,-DRB1, and -DQ Loci
    (2019) MARIANO, Livia; ZHANG, Bing Melody; OSOEGAWA, Kazutoyo; LOWSKY, Robert; FERNANDEZ-VINA, Marcelo
    Allogeneic hematopoietic stem cell transplant from an HLA matched sibling donor is usually the preferable choice. The use of next-generation sequencing (NGS) for HLA typing in clinical practice provides broader coverage and higher resolution of HLA genes. We evaluated the frequency of DPB1 crossing-over events among patients and potential related donors typed with NGS. From July 2016 to January 2018, 593 patients and 2385 siblings were typed. We evaluated sibling matching status in 546 patients, and 44.8% of these patients had siblings that matched at HLA-A, -B, -C, -DRB1, and -DQB1 loci. In 306 patient-HLA matched sibling pairs, we found 6 pairs (1.96%) with 1 DPB1 mismatch, and 5 of these pairs included an additional mismatch in DPAl. No additional mismatches were observed at the low expression loci. Using the T cell epitope algorithm, 4 of these DP mismatches were classified as permissive, 1 as nonpermissive in the host-versus-graft direction, and 1 as nonpermissive in the graft-versushost direction. The frequency of DPB1 and DPA1 mismatches is low, and their impact in related donor transplants is not well established. Although DP typing in related transplants goes beyond guidelines, it is especially relevant for sensitized patients. NGS-based HLA typing provides full gene coverage, and its use in clinical practice can enable better donor selection. (C) 2019 American Society for Transplantation and Cellular Therapy.

    Fertility Potential and Gonadal Function in Survivors of Reduced-Intensity Hematopoietic Stem Cell Transplantation
    (2024) ROTZ, Seth J.; HAMILTON, Betty K.; WEI, Wei; AHMED, Ibrahim; WINSTON, Sameeya Ahmed; BALLARD, Sherri; BERNARD, Robyn J.; CARPENTER, Paul; FARHADFAR, Nosha; FERRARO, Christina; FRIEND, Brian D.; GLOUDE, Nicholas J.; HAYASHI, Robert J.; HOYLE, Kerry; JENSSEN, Kari; KOO, Jane; LEE, Catherine J.; MARIANO, Livia; NAWABIT, Rawan; NGWUBE, Alexander; LALEFAR, Nahal; PHELAN, Rachel; PERKINS, Laynie; RAO, Anandini; RAYES, Ahmad; SANDHEINRICH, Taryn; STAFFORD, Lauren; TOMLINSON, Kathryn; WHITESIDE, Stacy; WIEDL, Christina; MYERS, Kasiani
    The use of reduced -intensity conditioning (RIC) regimens has increased in an effort to minimize hematopoietic stem cell transplantation (HCT) end -organ toxicity, including gonadal toxicity. We aimed to describe the incidence of fertility potential and gonadal function impairment in adolescent and young adult survivors of HCT and to identify risk factors (including conditioning intensity) for impairment. We performed a multi -institutional, international retrospective cohort study of patients age 10 to 40 years who underwent first allogeneic HCT before December 1, 2019, and who were alive, in remission, and available for follow-up at 1 to 2 years post-HCT. For females, an AMH level of >.5 ng/mL defined preserved fertility potential; an AMH level of >.03 ng/mL was considered detectable. Gonadal failure was defined for females as an elevated follicle -stimulating hormone (FSH) level >30 mIU/mL with an estradiol (E2) level <17 pg/mL or current use of hormone replacement therapy (regardless of specific indication or intent). For males, gonadal failure was defined as an FSH level >10.4 mIU/mL or current use of hormone replacement therapy. A total of 326 patients (147 females) were available for analysis from 17 programs (13 pediatric, 4 adult). At 1 to 2 years post-HCT, 114 females (77.6%) had available FSH and E2 levels and 71 (48.3%) had available AMH levels. FSH levels were reported for 125 males (69.8%). Nearly all female HCT recipients had very low levels of AMH. One of 45 (2.2%) recipients of myeloablative conditioning (MAC) and four of 26 (15.4%) recipients of reduced -intensity conditioning (RIC) ( P = .06) had an AMH >.5 ng/m, and 8 of 45 MAC recipients (17.8%) and 12 of 26 RIC recipients (46.2%) ( P = .015) had a detectable AMH level. Total body irradiation (TBI) dose and cyclophosphamide equivalent dose (CED) were not associated with detectable AMH. The incidence of female gonadal hormone failure was 55.3%. In univariate analysis, older age at HCT was associated with greater likelihood of gonadal failure (median age, 17.6 versus 13.9; P < .0001), whereas conditioning intensity (RIC versus MAC), TBI, chronic graft -versushost disease requiring systemic therapy, and CED were not significantly associated with gonadal function. In multivariable analysis, age remained statistically significant (odds ratio [OR]. 1.11; 95% confidence interval [CI], 1.03 to 1.22) for each year increase; P = .012), Forty-four percent of the males had gonadal failure. In univariate analysis, older age (median, 16.2 years versus 14.4 years; P = .0005) and TBI dose ( P = .002) were both associated with gonadal failure, whereas conditioning intensity (RIC versus MAC; P = .06) and CED ( P = .07) were not statistically significant. In multivariable analysis, age (OR, 1.16; 95% CI, 1.06-1.27 for each year increase; P = .0016) and TBI >600 cGy (OR, 6.23; 95% CI, 2.21 to 19.15; P = .0008) remained significantly associated with gonadal failure. Our data indicate that RIC does not significantly mitigate the risk for gonadal failure in females or males. Age at HCT and (specifically in males) TBI use seem to be independent predictors of post -transplantation gonadal function and fertility status. All patients should receive pre-HCT infertility counseling and be offered appropriate fertility preservation options and be screened post-HCT for gonadal failure.
