Trend and treatment patterns of aplastic anemia in Korea, pure red cell aplasia and myelodysplastic syndrome in Korea: a nation-wide analysis.

Trend and treatment patterns of aplastic anemia in Korea, pure red cell aplasia and myelodysplastic syndrome in Korea: a nation-wide analysis. Int J Hematol. 2017 Jun 29;: Authors: Choi Y, Jo JC, Jeon HJ, Kim DW, Chang MH, Kim H Abstract Aplastic anemia (AA) and pure red cell aplasia (PRCA) appear to be more prevalent in Asian countries including Korea. However, there are no exact data regarding its prevalence and frequency of allogeneic hematopoietic cell transplantation (HCT) in Korea. Here, we present demographic data relating to AA/PRCA/MDS in Korea. Data were prepared by retrieval from a computerized database maintained by the National Health Insurance Service and Korea National Statistical Office. HCT data were collected from all HCT centers in Korea. The crude incidence rate of AA decreased from 2002 to 2010 and from 35 to 28 per million persons. Females were more affected by AA. The peak ages of onset of AA were in the seventh decade or older. The frequency of HCT for AA increased from 2002 to 2012 and from 69 to 131 per year. The crude incidence rates of MDS increased from 2002 to 2010, with 8-20 per million persons, and the frequency of HCT also increased, from 30 in 2002 to 132 in 2011. Even allowing for the possibility of overestimation, the crude incidence of AA is significantly higher in Korea than in western countries. PMID: 28664500 [PubMed - as supplied by publisher]

We describe conditional survival and cause-specific mortality (disease-related [DRM], non-disease-related [NDRM], and GvHD-related) after alloHCT to provide clinically relevant information for patients who have survived 6 mos, 1, 2, 5, and 10y after alloHCT. Methods: From 1976 to 2013, 4,315 consecutive patients underwent alloHCT for hematologic diseases at a single institution. Vital status and cause of death were determined using the National Death Index Plus and medical records. Results: Diagnoses included acute leukemia (54%), chronic leukemia (17%), lymphoma (11%), myelodysplastic syndrome (10%), severe aplastic anemi...

Conclusions. ISV is widely used in hematological pts with IFI also in diseases other than acute myeloid leukemia and it is overall well tolerated. ORR to ISV is at least comparable with other antifungal agents. A rec/ref underlying hematological disease impacts both on OS and response to ISV, while having an IFI refractory to other antifungal agents including azoles does not seem to compromise the response to ISV, although this promising result should be confirmed in prospective studies and larger groups of patients.DisclosuresBusca: Gilead: Honoraria, Membership on an entity's Board of Directors or advisory committees, Sp...

In conclusion, the data suggest that patients with HL have a significantly higher incidence of AA compared to the general population. The underlying reason for this association is not known; however, the development of AA after HL, a unique B-cell neoplasm associated with a marked inflammatory component, without having received prior cytotoxic therapy in half of the cases, points to secondary immune dysregulation as the possible etiologic factor for AA pathogenesis. Recognition of this syndrome and improved management algorithms are needed for the management of AA presenting in patients with HL.DisclosuresFrey: Novartis: C...

Post-transplant lymphoproliferative disorder (PTLD) following hematopoietic stem cell transplantation (HSCT) is a rare, but life-threatening complication. PTLD typically develops within 6-12 months of HSCT, which is before the reconstitution of EBV-specific cytotoxic T-cell immunity. Several risk factors for developing PTLD have been reported in the literature, including the use of antithymocyte globulin (ATG) and ex vivo T-cell depletion (TCD). However, only a few large-scale retrospective studies have been conducted and risk scores have not yet been well defined. Therefore, to further evaluate the probability of and risk...

Background: Previous studies suggest that survival improves when patients (pts) with rare cancers are treated at specialty centers. Majority of MDS cases in the US are diagnosed in the communities. There is a perception that outcome of higher-risk MDS pts treated in communities is inferior when compared to specialty centers for several reasons, including the diagnostic complexities of MDS leading to treatment delays, complicated criteria for assessing treatment response, limited availability of clinical trials when hypomethylating agents (HMAs) fail and limited access to transplant referrals, among others. Integrating data...

Background:MDS and AML are mostly found in elderly patients. However, even in this population there is increasing evidence of predisposing genetic conditions, which have been underdiagnosed so far. Identifying inherited predisposition to myeloid disorders can be crucial especially in the context of hematopoietic stem cell transplantation (HSCT).Germline mutations in the DEAD/H-box helicase gene DDX41 have been identified in families with multiple cases of MDS or AML but also in sporadic cases. We aimed to analyze the prevalence and clinical features of DDX41-related myeloid malignancies within an unselected cohort of pts d...

Background: BK virus (BKV) is a human polyomavirus. Reactivation occurs during deep immunosuppression as in hematopoietic stem cell transplantation (HSCT) and renal transplantation, leading to hemorrhagic cystitis (HC) and nephropathy respectively. In HSCT, systematic PCR for BKV in urine is positive for 50 to 100% of patients (pts), but only 5 to 40% develop a BKV HC. Thus, BKV PCR is usefull to confirm a diagnostic of BKV HC but not to predict its occurrence. Several risk factors to develop BKV HC have been studied, especially mismatched HLA and haploidentical HSCT.Objectives: The aim of this retrospective study was to a...

ConclusionsEspecially during acute skin and intestinal GvHD, PCT and CRP values strongly and significantly increased beyond the upper normal limits. Simultaneous elevations of PCT and CRP occurred during graft rejection, skin and intestinal GvHD, and sepsis. Taken together, laboratory-chemical analyses of serum PCT in combination with CRP could be a useful discriminative biomarker in the detection of TRAE. Larger, prospective trials are needed, to evaluate these findings.FigureFig. 1. PCT and CRP serum concentrations during acute GvHD, graft rejection, VOD, sepsis, viremia and fungemia.
