Supportive Care During Pediatric Hematopoietic Stem Cell Transplantation: Prevention of Infections. A Report From Workshops on Supportive Care of the Paediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT)

Specific protocols define eligibility, conditioning, donor selection, graft composition and prophylaxis of graft vs. host disease for children and young adults undergoing hematopoietic stem cell transplant (HSCT). However, international protocols rarely, if ever, detail supportive care, including pharmaceutical infection prophylaxis, physical protection with face masks and cohort isolation or food restrictions. Supportive care suffers from a lack of scientific evidence and implementation of practices in the transplant centers brings extensive restrictions to the child's and family's daily life after HSCT. Therefore, the Board of the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) held a series of dedicated workshops since 2017 with the aim of initiating the production of a set of minimal recommendations. The present paper describes the consensus reached within the field of infection prophylaxis.

Male Gonadal Function After Pediatric Hematopoietic Stem Cell Transplantation : A Systematic Review

Male gonadal dysfunction is a frequent late effect after pediatric hematopoietic stem cell transplantation (HSCT) that can lead to disturbances in pubertal development, sexual dysfunction, and infertility. However, no systematic review exists regarding prevalence and risk factors in relation to different treatment regimens. We aimed to sys-tematically evaluate the current evidence regarding the prevalence of male gonadal dysfunction after pediatric HSCT, related risk factors, and the diagnostic value of surrogate markers of spermatogenesis in this patient group. We searched PubMed and Embase using a combination of text words and subject terms. The eligibility screening was conducted using predefined criteria. Data were extracted corresponding to the Leydig cell compartment involved in testosterone production and the germ cell compartment involved in spermatogenesis, respectively. Subsequently, data synthesis was performed. Of 2369 identified records, 25 studies were eligible. The studies were heterogeneous in terms of included diagnoses, gonadotoxic therapy, follow-up time, and definitions of gonadal dysfunction. The data synthesis revealed a preserved Leydig cell function in patients treated with non -total body irradiation (TBI) regimens, whereas the evidence regarding the impact of TBI conditioning on Leydig cell function was conflicting. Based on surrogate markers of spermatogenesis and only limited data on semen quality, the germ cell compartment was affected in half of the patients treated with non-TBI regimens and in nearly all patients treated with TBI conditioning. Testicular irradiation as part of front-line therapy before referral to HSCT led to complete Leydig cell failure and germ cell failure. Evidence regarding the impact of diagnosis, pubertal stage at HSCT, and chronic graft-versus-host disease is limited, as is the evidence of the diagnostic value of surrogate markers of spermatogenesis. Testicular irradiation as part of front-line therapy and TBI conditioning are the main risk factors associated with male gonadal dysfunction after pediatric HSCT; however, impaired sper-matogenesis is also observed in half of the patients treated with non-TBI regimens. Methodological shortcomings limit existing evidence, and future studies should include semen quality analyses, follow-up into late adulthood, and evaluation of the cumulative exposure to gonadotoxic therapy.

Male Sexual Function after Allogeneic Hematopoietic Stem Cell Transplantation in Childhood: A Multicenter Study

There are many known endocrine complications after allogeneic hematopoietic stem cell transplantation (HSCT) in childhood including increased risk of biochemical hypogonadism. However, little is known about sexuality in adulthood following childhood HSCT. In this multicenter study, sexual functions and possible risk factors were assessed comprehensively in two national cohorts (Finland and Denmark) of male adult survivors of childhood HSCT. Compared to a healthy control group (n = 56), HSCT survivors (n = 97) reported less sexual fantasies, poorer orgasms, lower sexual activity with a partner and reduced satisfaction with their sex life, even in the presence of normal erectile functions and a similar frequency of autoerotic acts. Of the HSCT survivors, 35% were cohabitating/married and 66% were sexually active. Risk factors for poorer self-reported sexual functions were partner status (not cohabitating with a partner), depressive symptoms, CNS and testicular irradiation. Sexual dysfunction increased by age in the HSCT group with a pace comparable to that of the control group. However, because of the lower baseline level of sexual functions in the HSCT group, they will reach the level of clinically significant dysfunction at a younger age. Hence, male survivors of childhood HSCT should be interviewed in detail about their sexual health beyond erectile functions

Physical Fitness and Frailty in Males after Allogeneic Hematopoietic Stem Cell Transplantation in Childhood: A Long-Term Follow-Up Study

Purpose and methods: To analyze physical fitness, physical activity and the prevalence of frailty in male long-term survivors of pediatric allogeneic hematopoietic stem cell transplantation (HSCT). We performed a Nordic two-center study of 98 male survivors (mean age 28.7 years, range 18.5–47.0) treated with pediatric allogeneic hematopoietic stem cell transplantation (HSCT) 1980–2010 in denmark or finland. physical fitness was evaluated by the dominant hand grip-strength, timed up-and-go, sit-to-stand, gait speed and two-minute walk tests. Results: Survivors presented significantly lower muscle strength and muscle endurance in the dominant hand-grip strength (median Z-score −0.7, range −4.3–3.9) and sit-to-stand tests (median Z-score −1.5, range −3.5–2.5) compared to age and sex matched normative values of the tests. However, mobility and gait speed were not affected on a group level. The prevalence of frailty (pre-frail 20% or frail 10%) was high among the survivors. In multiple regression analysis, chronic graft-versus-host disease, shorter stature, higher body fat mass and hazardous drinking predicted prefrail/frail status. Common cardiovascular risk factors, such as increased levels of serum triglycerides, higher resting heart rate and diastolic blood pressure, were associated with lower physical fitness. Conclusion: Low muscle strength and a high incidence of frailty were observed in survivors of pediatric HSCT. There is a predominant risk of cardiovascular and metabolic diseases in the long-term

Physical Fitness and Frailty in Males after Allogeneic Hematopoietic Stem Cell Transplantation in Childhood : A Long-Term Follow-Up Study

Simple Summary The prevalence of frailty is increased among young adult childhood cancer survivors and is associated with early morbidity and mortality. The aim of our study was to analyze physical fitness, physical activity and the prevalence of frailty in male long-term survivors of pediatric allogeneic hematopoietic stem cell transplantation. We observed significantly lower muscle strength and muscle endurance in the hand-grip and sit-to-stand tests compared to the age and sex matched normative reference values of the tests. Furthermore, 30% of the survivors were considered pre-frail or frail. Chronic graft-versus-host disease, shorter stature, higher body fat mass and hazardous drinking predicted prefrail/frail status. Common cardiovascular risk factors were associated with poor physical fitness and low physical activity level. These results indicate a need for cardiometabolic follow up as well as health education in the decades following HSCT.
