Permanent alopecia after haematopoietic stem cell transplantation (HSCT) is distressing and few studies have investigated this late effect. The aim of the study was to assess the percentage of patients with alopecia and investigate risk factors for alopecia. Patients who underwent allogeneic HSCT before age 19 years, from January 1990 to January 2013, who were at least 2 years after transplant and in follow-up in our clinic were included. Alopecia was defined as clinically apparent decreased hair density. Possible risk factors considered for alopecia after HSCT included: gender, age, diagnosis, donor type, conditioning regimen: cranial irradiation (TBI/cranial radiotherapy) and/or chemotherapy, which chemotherapeutic agents were used and acute/chronic GvHD. The percentage of permanent alopecia in our cohort was 15.6% (41/263 patients). All patients had diffuse alopecia except for one with alopecia totalis. In multivariate analysis, a conditioning regimen with busulphan and busulphan plus fludarabine (odds ratio (OR) 5.7 (confidence interval (CI): 2.5-12.7) and OR 7.4 (CI: 3.3-16.2), respectively, was the main risk factor and associated with alopecia independent of acute/chronic GvHD. Neither TBI nor other alkylating chemotherapy, including treosulfan, was associated with alopecia. In conclusion, permanent alopecia after HSCT is associated with busulphan and GvHD and occurs in 16% of patients.

Fifty-three adults who had received SCT as children responded to questionnaires on health-related quality of life (HRQoL) (Swedish HRQoL survey (SWED-QUAL)), sense of coherence (SOC), anxiety and depression (HAD) and a health and symptom inventory. Late effects were classified following the Common Terminology Criteria for Adverse Events (CTCAE) v. 3.0. HRQoL was below norm in 9 of 13 SWED-QUAL domains. Poorest domains (P

Chronic kidney disease (CKD) has been related to allogeneic haematopoietic cell transplantation (HCT) as a late effect caused by a variety of factors. We retrospectively evaluated the development of CKD in 230 patients, aged 34 (5-65) years, who had undergone allogeneic HCT for haematological disease, using sibling or unrelated donors and myeloablative or reduced conditioning regimens. Pre-HCT glomerular filtration rate (GFR) was within normal limits (108±28 mL/min/1.73 m(2)) in patients who did not develop CKD and 95±24 mL/min/1.73 m(2) in those with CKD postHCT, while the GFR 12 months post transplant declined to 104±26 and 69±19 mL/min/1.73 m(2), respectively. CKD incidence was 20.4%, with a median time of development of 6 (3-18) months post transplant. On multivariate analysis, risk factors for CKD were the presence of chronic GVHD (cGVHD; P=0.001), unrelated donor transplantation (P=0.008), post-transplant event of acute kidney injury (AKI) (P=0.002) and older age (P=0.002). In long-term survivors stable significant predictors for CKD were older age at transplantation, cGVHD and AKI. CKD did not influence non-relapse mortality. In our study, cGVHD emerges as an important cause of kidney injury in HCT survivors, regardless of administration of nephrotoxic agents.

Infertility is a major late effect in patients receiving haematopoietic stem cell transplantation (HSCT). The aim of this study was to determine the proportion of patients having fertility impairment after allogeneic HSCT in childhood/adolescence and to identify the potential risk factors. Treatment and fertility data of paediatric patients with malignant and non-malignant diseases treated with allogeneic HSCT between 2000 and 2005 were collected from seven European centres. Data were obtained for 138 female and 206 male patients after a median follow-up of 6 years (range 3-12). The patients' median age was 13 years (range 4-28) at the time of HSCT and 19 (range 12-35) years at the time of the enquiry. Seven children were born to the overall group, all at term and healthy. Fertility impairment was suspected in 69% males and 83% females. Start of treatment at age 13 years was a risk factor in females (odds ratio (OR) 4.7; 95% confidence interval (CI), 1.5 to 14.9), whereas pre-pubertal therapy was a risk factor in males (OR 0.4; 95% CI, 0.2 to 0.8). The major treatment-related risk factors were BU in females (OR 47.4; 95% CI, 5.4 to 418.1) and TBI in males (OR 7.7; 95% CI, 2.3 to 25.4). In light of the significant proportion of HSCT patients reviewed with impaired fertility, fertility conservation procedures should be considered for all patients undergoing HSCT, particularly those receiving TBI or BU-based preparative regimens.

We present a set of tests for physical performance used for annual prospective follow-up after a pediatric transplant. Of the 103 eligible patients transplanted at a mean age of 8.8 years, 94 were included. The results were divided into early, performed 1 (n=46) or 2 (n=12) years post transplant, and late tests (n=66), performed 4-16 (mean 6) years post transplant. A total of 30 patients had tests both at early and late time points (paired tests). The control subjects included 522 healthy age- and gender-matched schoolchildren. Using their test results, the s.d. score (SDS) was calculated for each patient and for each test individually. Both in the early and late tests, patients had the mean SDS for each test significantly lower (P

Ovarian function and sex hormone production with special focus on androgens (testosterone, androstenedione, dehydroepiandrosterone and its sulfate, DHEAS) was followed up during 1.5–20 (mean 9) years after bone marrow transplantation (BMT) in 24 female subjects aged 16–33 (mean 21) years at the last follow-up. All patients had received TBI and high-dose chemotherapy as the preparative regimen. A total of 24 female patients with conventionally treated pediatric hematologic malignancies served as controls. Four of 24 transplanted patients had spontaneous menstruation several years post transplantation, but in only one of them were serum FSH levels normal. Androgen levels of the BMT patients were lower than those of the conventionally treated patients. Subnormal testosterone levels were observed in 43% of BMT patients and subnormal DHEAS levels in 34% of BMT patients, the latter being a constant finding during glucocorticoid therapy for chronic GVHD (cGVHD). These results indicate that ovarian damage is a common late effect in patients transplanted at a young age, still having a seemingly normal pubertal development. Ovarian damage and cGVHD with glucocorticoid therapy are strongly associated with subnormal androgen levels. The clinical consequences of these changes and possible benefits of putative androgen replacement therapy remain to be elucidated.
