Case ReportsRuxolitinib treatment for GvHD in patients with myelofibrosis.
Jak1/2 inhibitor ruxolitinib is a promising agent for treating steroid-refractory GvHD after allogeneic hematopoietic stem cell transplantation (SCT) to produce quick and durable responses. However, optimal dose and tapering schedule of ruxolitinib remain to be determined. Discontinuation of ruxolitinib in myelofibrosis often induces 'withdrawal syndrome' characterized by acute relapse of the disease, but this issue is not well addressed in the treatment of GvHD. ⋯ Withdrawal syndrome developed in one patient, who died of recurrence of GvHD shortly after discontinuation of ruxolitinib. Slow tapering or maintenance with low-dose ruxolitinib inhibited GvHD flare. Our experience calls attention that initiation at low-dose of ruxolitinib may be safe and careful tapering schedule is required to avoid withdrawal syndrome in patients with GvHD after SCT for myelofibrosis.

Comparative StudyComparable outcomes between younger (⩽40 years) and older (>40 years) adult patients with severe aplastic anemia after HLA-matched sibling stem cell transplantation using fludarabine-based conditioning.
Allogeneic stem cell transplantation from HLA-matched siblings (MSD-SCT) for elderly patients with severe aplastic anemia (SAA) is not a widely accepted first-line treatment. Recently, fludarabine, lower-dose cyclophosphamide and antithymocyte globulin conditioning (Flu/lower-dose Cy/ATG) with lower toxicities has been investigated. To determine whether this regimen can overcome the negative effects of age, we analyzed 117 adult patients with SAA who received MSD-SCT using Flu/lower-dose Cy/ATG, and compared outcomes between 63 younger age group (YAG; ⩽40 years) and 54 older age group (OAG; >40 years) patients. ⋯ The incidences of acute grade II-IV (9.5% vs 9.3% at day 100; P=0.42) and chronic GVHD (8.1% vs 9.5% at 5 years; P=0.80), secondary graft failure (20.8% vs 7.9% at 5 years; P=0.11) and transplant-related mortality (5.4% and 11.1% at 5 years; P=0.91) were not significantly different between the YAG and OAG. In addition, failure-free (73.7% vs 81.0% at 5 years; P=0.73) and overall survival rates (93.7% vs 88.9% at 5 years; P=0.20) were comparable. Our results suggest that MSD-SCT using Flu/lower-dose Cy/ATG may be a feasible first-line treatment even in older patients with SAA.

Case ReportsDisseminated cryptococcal infection in allogeneic stem cell transplant patients: a rare cause of acute kidney injury.
Hematopoietic stem cell transplantation (HSCT) can be lifesaving for some of the deadliest hematologic diseases. However, immunosuppression, polypharmacy and risk of infectious complications associated with HSCT can increase morbidity and mortality for recipients. ⋯ Kidney biopsy showed round to cup-shaped organisms with occasional budding, consistent with Cryptococcus and thrombotic microangiopathy. We discuss our findings and a literature review of disseminated cryptococcal infection with renal involvement after HSCT.
