The aim of this study was to assess the degree of spermatogenesis defects in sperm analysis in long-term male survivors after allogeneic hematopoietic stem cell transplantation in order to identify the risk factors related to potential infertility after hematopoietic stem cell transplantation and to provide data on longitudinal sperm recovery after hematopoietic stem cell transplantation. Here, the Late Effects Working Party of the European Group for Blood and Marrow Transplantation reports data of sperm analysis from 224 males who underwent hematopoietic stem cell transplantation. Median time between transplantation and sperm analysis was 63 months (8-275 months). At last sperm analysis, presence of any degree of spermatozoa was reported in 70 (31%) and complete azoospermia in 154 (69%) patients. In multivariate analysis, being conditioned with total body irradiation (RR 7.1; 95% CI: 3.4-14.8) and age over 25 years at transplantation (RR 2.4; 95% CI: 1.09-5.2) were significantly associated with higher risk for azoospermia. In patients not conditioned with total body irradiation, ongoing chronic graft-versus-host disease is the main adverse factor for sperm recovery (RR of 3.11; 95% CI: 1.02-9.47; P=0.045). Already established risk factors, such as total body irradiation and age older than 25 years at hematopoietic stem cell transplantation, were seen to be the most relevant adverse risk factor for sperm production after hematopoietic stem cell transplantation. Furthermore, for the first time, ongoing graft-versus-host disease has been shown to be the most relevant adverse factor for sperm recovery, particularly in patients conditioned without total body irradiation. We also introduce a useful scoring system to predict the probability of male long-term survivors' azoospermia.

Immune Thrombocytopenia Purpura (ITP) secondary to vaccinations is rare, especially after autologous hematopoietic stem cell transplantation (HSCT). A 31-yearold female received autologous HSCT for relapsed Hodgkin Disease, with platelet engraftment at Day+14. One week after receiving second scheduled vaccinations, she developed severe thrombocytopenia (3x109/L) associated with pharyngeal hematoma. Bone marrow (BM) examinations were consistent with ITP, possibly secondary to Influenza vaccine. Platelet increment was poor despite high dose corticosteroids, intravenous immunoglobulin (IVIG), Danazol and Eltrombopag. A repeated BM biopsy was in agreement with ITP. Re-treatment with tapering doses of prednisolone resulted in stable platelet counts at 120x109/L a year later.

INTRODUCTION: Hematopoietic Stem Cell Transplantation (HSCT) is a life-saving procedure for multiple types of hematological cancer, autoimmune diseases, and genetic-linked metabolic diseases in humans. Recipients of HSCT transplant are at high risk of microbial infections that significantly correlate with the presence of graft-versus-host disease (GVHD) and the degree of immunosuppression. Infection in HSCT patients is a leading cause of life-threatening complications and mortality.
AREAS COVERED: This review covers issues pertinent to infection in the HSCT patient, including bacterial and viral infection; strategies to reduce GVHD; infection patterns; resistance and treatment options; adverse drug reactions to antimicrobials, problems of antimicrobial resistance; perturbation of the microbiome; the role of prebiotics, probiotics, and antimicrobial peptides. We highlight potential strategies to minimize the use of antimicrobials.
EXPERT OPINION: Measures to control infection and its transmission remain significant HSCT management policy and planning issues. Transplant centers need to consider carefully prophylactic use of antimicrobials for neutropenic patients. The judicious use of appropriate antimicrobials remains a crucial part of the treatment protocol. However, antimicrobials' adverse effects cause microbiome diversity and dysbiosis and have been shown to increase morbidity and mortality.

INTRODUCTION: Ruxolitinib is the first approved drug for treatment of myelofibrosis, but its impact of outcome after allogeneic stem cell transplantation (ASCT) is unknown.
PATIENTS AND METHODS: We reported on 159 myelofibrosis patients (pts) with a median age of 59 years (r: 28-74) who received reduced intensity ASCT between 2000 and 2015 in eight German centers from related (n = 23), matched (n = 86) or mismatched (n = 50) unrelated donors. Forty-six (29%) patients received ruxolitinib at any time point prior to ASCT. The median daily dose of ruxolitinib was 30 mg (range 10-40 mg) and the median duration of treatment was 4.9 months (range 0.4-39.1 months).
RESULTS: Primary graft failure was seen in 2 pts (4%) in the ruxolitinib and 3 (2%) in the non-ruxolitinib group. Engraftment and incidence of acute GVHD grade II to IV and III/IV did not differ between groups (37% vs 39% and 19% vs 28%, respectively), nor did the non-relapse mortality at 2 years (23% vs 23%). A trend for lower risk of relapse was seen in the ruxolitinib group (9% vs 17%, P = .2), resulting in a similar 2 year DFS and OS (68% vs 60% and 73% vs 70%, respectively). No difference in any outcome variable could be seen between ruxolitinib responders and those who failed or lost response to ruxolitinib.
CONCLUSIONS: These results suggest that ruxolitinib pretreatment in myelofibrosis patient does not negatively influence outcome after allogeneic stem cell transplantation.
