RESUMEN

A successful Hematopoietic stem cell transplantation (HSCT) is often the only hope of survival for children suffering from a range of potentially life-threatening hematological malignancies. The financial, ethical, and emotional problems faced by the matched sibling donor and their recipient siblings during the HSCT are extremely complex and challenging. Herein, the authors have attempted to pen down these in the configuration of a poem.

RESUMEN

The rapid onset and worldwide spread of the COVID-19 epidemic (caused by SARS-CoV-2 coronavirus) has been associated with a profound impact in clinical practice also in the hematologic setting. First of all, given the immunosuppressive effect of many therapies that are normally administered to patients with hematological diseases, with a consequent increased risk of contracting a more severe viral infection, it has been necessary to reconsider in each individual patient the urgency and priority of the treatments foreseen by the normal standards of care. In particular, as regards allogeneic (and to a lesser extent autologous) hematopoietic cell transplantation and CAR T-cell therapy, specific recommendations have been issued by the transplant community on the criteria to be used to decide whether or not to postpone these procedures and on the clinical management of recipients and donors exposed to COVID-19. As to cytotoxic chemotherapy and other antineoplastic therapies, criteria have been proposed to decide, in the various clinical situations, which treatments were not deferrable and which instead could be postponed or replaced by less aggressive therapies. In the outpatient clinics, various organizational solutions for telemedicine have been adopted, resorting to telephone interviews and/or Information Technology, with the aim of reducing the influx of patients while maintaining an adequate control of their clinical condition. The collection of blood by the transfusion centers has been the subject of organizational measures, in order to avoid the transmission of COVID 19 while maintaining a sufficient blood collection for clinical needs. Finally, some hematologic laboratory alterations have been identified, such as thrombocytopenia, lymphopenia and coagulation abnormalities, useful for the prognostic evaluation of infected patients.

RESUMEN

Hematopoietic stem cells donation is an essential prerequisite of allogeneic transplantation. Both family donors and matched unrelated donors should have a conscious involvement in every phase of the overall path, from selection to HSC collection. Donors also should be informed about the right to withdraw at any time as well as the extreme risk for recipient's life coming from the decision of interrupting, if the donation is not carried out once the patient's preparative regimen has commenced. We report our challenging experience about a donor who withdraws her consent to HSC donation after 3 days of mobilization with G-CSF. The possibility of withdrawal protects the donor but it also puts at risk both a chance for a transplant and the patient's life if preparative regimen has started. Can the donor really be free to withdraw the consent to HSC donation at any time even when this endangers the life of a recipient? Is this ethical? However, if the donor decides to withdraw, would we really be ready to manage promptly all the consequences coming from the consent revocation? At the moment there is not a well-defined "plan B" in case of impossibility to proceed with the transplant when conditioning has already started or has even been completed. In our opinion, because of this hard balance and such a high risk, it would be necessary to plan every time an alternative strategy which may be different according to different circumstances.

RESUMEN

Early-infantile Krabbe disease (EIKD) is an autosomal recessive, progressive, neurodegenerative disorder that usually leads to death in infancy. A study published in 2005 indicated that hematopoietic stem-cell transplantation (HSCT) was effective in the treatment for EIKD when used before the onset of symptoms. This finding suggested that newborn screening for EIKD, which would allow earlier diagnosis, might lead to earlier treatment and better outcomes. In 2006, New York was the first state to implement newborn screening for Krabbe disease; however, the results were not as good as proponents had hoped. In this paper, we present the history of efforts to diagnose and treat EIKD. Based on our findings, we question the efficacy of newborn screening for Krabbe disease. We present two arguments. First, testing itself is too imprecise. Even with the most rigorous testing standards, such as those used in New York, many of the children who are identified as being 'at risk' for EIKD remain asymptomatic. It is unclear if they will remain asymptomatic forever and, thus, whether the tests should be considered 'false positives', or whether they will eventually develop the disease. Second, we question the efficacy of early HSCT. We recommend placing a moratorium on mandatory newborn screening for EIKD. WHAT THIS PAPER ADDS: Current tests to identify which children are likely to develop Krabbe diseased are inadequate. Many children identified as being 'at risk' for early infantile Krabbe disease remain asymptomatic. Psychosine appears to be more specific than low galactosylceramidase levels for diagnosing early infantile Krabbe disease.

RESUMEN

Availability of 8/8 HLA-allele matched unrelated donors (URDs) is a barrier for ethnic and racial minorities. We prospectively evaluated receipt of 8/8 HLA-allele matched URD or either 7/8 URD or cord blood (CB) transplants by patient ancestry from 2005 to 2017. Matched URDs were given priority if they were available. Of 1312 patients, 723 (55%) received 8/8 URD, 219 (17%) 7/8 URD, 319 (24%) CB, and 51 (4%) had no 7/8 or 8/8 URD or CB graft. Europeans were more likely to receive an 8/8 URD transplant than non-Europeans (67% vs 33%) and less likely to have no URD or CB graft (1% vs 9%). Southern Europeans received 8/8 URD transplants (41%) at rates similar to those of Asians (34%) and white Hispanics (35%); Africans were the least likely (18%) to undergo 8/8 URD transplantation. CB and 7/8 URDs extended transplant access to all groups. In 742 recent patients, marked racial disparity in 8/8 URD access between groups observed in earlier years persisted with only a modest increase in the percentage of 8/8 URD transplants. Of 78 recent African patients, 46% received a CB transplant and 14% had no 7/8 or 8/8 URD or CB graft. Increasing registry size has not resolved the racial disparity in URD access, which emphasizes the importance of alternative graft sources.

RESUMEN

Many foreign parents bring their children to the United States for medical treatments that are unavailable in their own country. Often, however, parents cannot afford expensive treatments. Doctors and hospitals then face a dilemma. Is it ethically permissible to consider the patient's citizenship and ability to pay? In this Ethics Rounds, we present a case in which a child from another country needs an expensive treatment. His parents cannot afford the treatment. He has come to a public hospital in the United States. We present responses from experts in pediatrics, bioethics, and health policy.

RESUMEN

Hematopoietic cell transplantation (HCT) using an HLA-identical sibling donor offers a very high likelihood of cure with good outcomes for patients with sickle cell disease (SCD), and alternative donor HCT for SCD is an area of active clinical research. Thus, HCT is a potential option for a growing number of patients with SCD. This expanded use of HCT has raised several ethical questions. Who is eligible for HCT, in terms of both disease severity and psychosocial factors? Should affected children with matched sibling donors undergo HCT only when they have declared themselves as having significant symptomatology? Regarding donors, special ethical challenges include the use of preimplantation genetic diagnosis to conceive an HLA-identical sibling. In this review, we critically analyze various ethical challenges related to HCT for SCD, and offer recommendations to guide clinical care.

RESUMEN

Providing information to living donors is first and foremost a legal obligation as well as an ethical one, not to mention necessary to health care provision. It's been shown that quality of information concerning the procedure's practical aspects, scheduling of clinical tests and examinations, withdrawing stem cells for the donation, post-donation symptoms, and support provided by healthcare teams, directly impacts the donor's quality of experience. Taking this into consideration our group decided it was essential to create an informational support for donors in the form of a booklet to be provided in different hematopoietic stem cell transplant centers across France. In September 2016 in Lille, France, the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) organized the 7th allergenic hematopoietic stem cell transplantation clinical practices harmonization workshops. As part of these workshops, our group worked collectively to develop a basis of indispensable information to be included in the booklet and presented using clear and accessible language.

RESUMEN

Informed consent is not restricted to clinical research and must be applied to high-risk care such as hematopoietic stem cell transplantation. If standardized informed consent might improve inequalities in medical practices between different transplantation centers, it is strongly recommended that it be adapted with an honest dialogue between physicians and patients and physicians and donors. In an attempt to harmonize clinical practices among French hematopoietic stem cell transplantation centers, the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) held its sixth annual workshop series in September 2015 in Lille. This event brought together practitioners from across the country. The purpose of this paper is to highlight the French law concerning patients' rights and ethical practices for an informed consent process to be applied to care or research.

RESUMEN

The most suitable donor for younger patients who undergo hematopoietic stem cell transplantation in the research setting is frequently a minor sibling. These cases raise the question of whether minors who serve as stem cell donors for research subjects should be regarded as research subjects themselves. Regarding pediatric donors as research subjects ensures that an Institutional Review Boards reviews their involvement and determines whether it is appropriate. Yet, Institutional Review Boards must follow the US regulations for pediatric research, which were designed for patients and healthy volunteers, not for healthy donors. As a result, regarding pediatric donors as research subjects also can pose unnecessary obstacles to appropriate and potentially life-saving research. This article considers a new way to address this dilemma. The federal research regulations allow for waiver of some or all of the included requirements when they are unnecessary for a study or a class of studies. We argue that this option offers a way to ensure that the involvement of pediatric donors receives sufficient review and approval without inadvertently undermining valuable and potentially life-saving research.

RESUMEN

Mismatch of human leukocyte antigens (HLA) adversely impacts the outcome of patients after allogeneic hematopoietic stem-cell transplantation (alloHSCT). This translates into the clinical requirement to timely identify suitable HLA-matched donors which in turn curtails the chances of recipients, especially those from a racial minority, to successfully undergo alloHSCT. We thus sought to broaden the existing pool of registered unrelated donors based on analysis that eliminating the expression of the HLA-A increases the chance for finding a donor matched at HLA-B, -C, and -DRB1 regardless of a patient's race. Elimination of HLA-A expression in HSC was achieved using artificial zinc finger nucleases designed to target HLA-A alleles. Significantly, these engineered HSCs maintain their ability to engraft and reconstitute hematopoiesis in immunocompromised mice. This introduced loss of HLA-A expression decreases the need to recruit large number of donors to match with potential recipients and has particular importance for patients whose HLA repertoire is under-represented in the current donor pool. Furthermore, the genetic engineering of stem cells provides a translational approach to HLA-match a limited number of third-party donors with a wide number of recipients.

RESUMEN

Allogeneic hematopoietic cell transplantation (alloHCT) may be the only curative option for some older adults with hematologic malignancies, and its associated risks of significant morbidity and mortality warrant a clear, informed decision-making process. As older adults have not been transplanted routinely until recent years, younger people have been the prototypical group around whom the current process has developed. Yet, this process is applied to older adults who have different considerations than younger patients when making their transplant decision. Older adults do not have the open-ended lives of younger patients and are entitled to consider how to spend their remaining time. They also possess maturity and experience, and with proper knowledge, they can make informed choices rather than moving forward in the transplant process unaware. Notably, older patients face similar problems with the informed decision-making process in nephrology. Strategies such as providing education about alloHCT gradually and repeatedly during induction, presenting recent knowledge from the literature in plain language, and utilizing a team approach to patient education may help older adults make the best decision about transplant in light of their situation and values. Understanding when and how older adults decide on alloHCT is an important first step to further exploring this problem.

RESUMEN

Related donors for hematopoietic cell (HC) transplantation are a growing population in recent years because of expanding indications for allogeneic transplantation. The safety and welfare of the donor are major concerns for the transplantation community, especially for related sibling donors of young recipients who are children and, thus, not able to fully consent. Because donation of HC does not improve the donor's own physical health and carries a risk of side effects, careful assessment of medical risks specific to the individual donor, as well as consideration of ethical and legal aspects associated with donation from a child, must be considered. In addition, donor centers must balance the needs of both the donor and the recipient, understanding the inherent conflict parents may have as they can be overly focused on the very sick child receiving a transplant, rather than on the relatively less significant health or emotional problems that a sibling donor may have, which could impact risk with donation. Likewise, consideration must be made regarding the nature of the relationship of the sibling donor to the recipient and also aspects of performing research on pediatric HC donors. In this article, as members of the Donor Issues Committee of the Worldwide Network for Blood and Marrow Transplantation, we review key ethical concerns associated with pediatric donation and then give recommendations for screening potential child donors with underlying health conditions. These recommendations are aimed at protecting the physical and emotional well-being of childhood donors and arise out of the Third International Conference on Health and Safety of Donors sponsored by the Worldwide Network for Blood and Marrow Transplantation.

RESUMEN

Umbilical cord blood transplants are now used to treat numerous types of immune- and blood-related disorders and genetic diseases. Cord blood (CB) banks play an important role in these transplants by processing and storing CB units. In addition to their therapeutic potential, these banks raise ethical and regulatory questions, especially in emerging markets in the Arab world. In this article, the authors review CB banking in five countries in the region, Jordan, Saudi Arabia, Egypt, Qatar, and the United Arab Emirates, selected for their different CB banking policies and initiatives. In assessing these case studies, the authors present regional trends and issues, including religious perspectives, policies, and demographic risk factors. This research suggests strong incentives for increasing the number of CB units that are collected from and available to Arab populations. In addition, the deficit in knowledge concerning public opinion and awareness in the region should be addressed to ensure educated decision-making.
