Risk factors for ICU admission and ICU survival after allogeneic hematopoietic SCT.
A considerable number of patients undergoing allogeneic hematopoietic SCT (HSCT) develop post-transplant complications requiring intensive care unit (ICU) treatment. Whereas the indications and the outcome of ICU admission are well known, the risk factors leading to ICU admission are less well understood. We performed a retrospective single-center study on 250 consecutive HSCT patients analyzing the indications, risk factors and outcome of ICU admission. ⋯ SAPS II score underestimated the mortality rate. In conclusion, acute GvHD and HLA mismatch were identified as risk factors for ICU admission following allogeneic HSCT. Both, short- and long-term survival of patients admitted to the ICU remains dismal and depends on the number of organ failures.

Clinical TrialCardiopulmonary fitness in patients undergoing hematopoietic SCT: a pilot study.
Hematopoietic cell transplantation (HCT) is a life-saving treatment for patients with high-risk hematological malignancies. Prognostic measures to determine fitness for HCT are needed to inform decision-making and interventions. VO(2peak) is obtained by measuring gas exchange during cycle ergometry and has not been studied as a prognostic factor in HCT. ⋯ Patients with pre-HCT VO(2peak) <16 mL/kg/min had higher risk of mortality post HCT (entire cohort: hazard ratio (HR) 9.1 (1.75-47.0), P=0.01; allogeneic HCT patients only: HR 6.70 (1.29-34.75), P=0.02) and more hospitalized days before Day 100 (entire cohort: median 33 vs 19, P=0.003; allogeneic HCT patients only: median 33 vs 21, P=0.004). VO(2peak) pre-HCT is feasible and might predict symptom severity, HRQOL and mortality. Additional studies are warranted.

Multicenter StudyCosts of autologous and allogeneic hematopoietic cell transplantation in the United States: a study using a large national private claims database.
There is a lack of multi-center cost-identification studies for hematopoietic cell transplantation (HCT). We used a single longitudinal administrative claims database representing a national, commercially insured population to evaluate the feasibility of identifying HCT recipients and to establish a cohort of autologous and allogeneic HCT recipients to study inpatient and outpatient direct medical costs from transplant hospitalization through first 100 days post-transplantation. Using ICD-9 procedure and diagnosis codes, we identified 3365 patients who had received their first transplant in the United States between 2007 and 2009 (autologous, 1678, allogeneic, 1320, graft source not specified, 367). ⋯ Costs were greater among pediatric (< or =20 years) compared with adult (>20 years) recipients and this difference was more pronounced with allogeneic HCT. Using a claims database representing a national HCT population, we highlight the high costs associated with autologous and allogeneic HCT. Our study lays the foundation for using claims data for future research on economic aspects of HCT.

Foscarnet against human herpesvirus (HHV)-6 reactivation after allo-SCT: breakthrough HHV-6 encephalitis following antiviral prophylaxis.
High incidences of human herpesvirus (HHV)-6 encephalitis have recently been reported from several Japanese SCT centers. To evaluate the effect of low-dose foscarnet (PFA) in preventing HHV-6 infection among recipients of unrelated BM or cord blood (CB), we examined consecutive cohorts without prophylaxis against HHV-6 (cohort 1, n=51) and with PFA prophylaxis (cohort 2, PFA 50 mg/kg/day for 10 days after engraftment, n=67). Plasma real-time PCR assay was performed weekly. ⋯ Breakthrough HHV-6 encephalitis occurred following PFA prophylaxis in three patients, and incidence of HHV-6 encephalitis did not differ between cohort 1 (9.9%) and cohort 2 (4.5%, P=0.24). In conclusion, 50 mg/kg/day of PFA does not effectively suppress HHV-6 reactivation and cannot prevent all cases of HHV-6 encephalitis. To effectively prevent HHV-6 encephalitis, alternative approaches based on the pathogenesis of HHV-6 encephalitis will probably be required.
