Detection of 1,3-β-d-glucan (BDG) in serum has been evaluated for its inclusion as a mycological criterion of invasive fungal infections (IFI) according to EORTC and Mycoses Study Group (MSG) definitions. BDG testing may be useful for the diagnosis of both invasive aspergillosis and invasive candidiasis, when interpreted in conjunction with other clinical/radiological signs and microbiological markers of IFI. However, its performance and utility vary according to patient population (hematologic cancer patients, solid-organ transplant recipients, intensive care unit patients) and pretest likelihood of IFI. The objectives of this article are to provide a systematic review of the performance of BDG testing and to assess recommendations for its use and interpretation in different clinical settings.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy with aggressive behavior and poor prognosis. We present the first retrospective analysis mapping its incidence and therapeutic outcomes in patients diagnosed and treated from 2000 to 2017 in the Czech Republic. The cohort comprised 14 patients (10 males, 4 females) with a median age at diagnosis of 39 years (range, 5-68 years). Initially, skin involvement was noted in 10 (71%) patients and bone marrow infiltration was present in 9 (64%). The first complete remission was achieved in 6/14 (43%) patients after acute lymphoblastic leukemia/lymphoma induction therapy and in 3/14 (21%) patients after acute myeloid leukemia regimen. Nine patients underwent allogeneic hematopoietic cell transplantation, with two patients achieving the first complete remission only after allogeneic transplantation. Patients undergoing allogeneic hematopoietic cell transplantation had longer overall survival than those treated without transplantation (the median survival over the period 16.4 vs. 8.1 months). Relapse of the disease was a significant predictor of mortality (p=0.05). Over the study period, patients' survival ranged from 3.3 to 44.2 months, with a median overall survival of 13 months. Our results revealed an effectivity of allogeneic hematopoietic cell transplantation on complete remission achievement in refractory/relapsed disease. The study aimed to present the actual data from the Czech Republic and thus contribute to a global understanding of BPDCN.

Therapy-related acute promyelocytic leukemia (t-APL) is relatively rare, with limited data on outcome after treatment with arsenic trioxide (ATO) compared to standard intensive chemotherapy (CTX). We evaluated 103 adult t-APL patients undergoing treatment with all-trans retinoic acid (ATRA) alone (n=7) or in combination with ATO (n=24), CTX (n=53), or both (n=19). Complete remissions were achieved after induction therapy in 57% with ATRA, 100% with ATO/ATRA, 78% with CTX/ATRA, and 95% with CTX/ATO/ATRA. Early death rates were 43% for ATRA, 0% for ATO/ATRA, 12% for CTX/ATRA and 5% for CTX/ATO/ATRA. Three patients relapsed, two developed therapy-related acute myeloid leukemia and 13 died in remission including seven patients with recurrence of the prior malignancy. Median follow-up for survival was 3.7 years. None of the patients treated with ATRA alone survived beyond one year. Event-free survival was significantly higher after ATO-based therapy (95%, 95% CI, 82-99%) as compared to CTX/ATRA (78%, 95% CI, 64-87%; P=0.042), if deaths due to recurrence of the prior malignancy were censored. The estimated 2-year overall survival in intensively treated patients was 88% (95% CI, 80-93%) without difference according to treatment (P=0.47). ATO when added to ATRA or CTX/ATRA is feasible and leads to better outcomes as compared to CTX/ATRA in t-APL.

Reduced-intensity conditioning (RIC) is widely used for allogeneic stem cell transplantation (SCT). Here we present our long-term experience with RIC regimen consisting of fludarabine (30 mg/m2/day on days -10 to -5), busulfan (4mg/kg/day on days -6 and -5) and antithymocyte globulin (ATG Fresenius, 10 mg/kg/day on days -4 to -1) (Flu-Bu-ATG) in a cohort of 71 patients with various hematological malignancies including chronic myeloid leukemia (24 patients), acute myeloid leukemia (19 patients), lymphoma (20 patients), multiple myeloma (3 patients), myelodysplastic syndrome (3 patients), and myelofibrosis (2 patients). The median age was 50 years. The overall response rate was 87%, including 83% CR and 4% PR. The incidence of acute and chronic GVHD was 35% and 52% and the cumulative incidence of non-relapse mortality at 1 year and 4 years was 8% and 14%. With the median follow-up of 55.0 months, the 2- and 4-year event-free survival (EFS) was 49.0% and 40.3%, and the overall survival (OS) was 73.2% and 62.6%, respectively. Gender, age at SCT, type of donor, disease status at SCT, previous autologous transplantation, and complete chimerism by day +100 did not significantly influence EFS and OS. In a multivariate analysis, no presence of chronic GVHD (p=0.029, HR: 2.5),and diagnosis other than CML (p=0.018, HR: 4.6), and CD34+ dose < 5x106/kg (p=0.010, HR: 2.8) were significant predictors of poor OS. Flu-Bu-ATG protocol is a RIC regimen that combines effective disease control with low non-relapse mortality and acceptable toxicity profile. Keywords: reduced-intensity conditioning, fludarabine, busulfan, antithymocyte globulin.
