2. Combined Selection System to Lower the Cutoff for Plasma Cell Enrichment Applied to iFISH Analysis in Multiple Myeloma

Author

Abstract

Multiple myeloma (MM) is a very heterogeneous disease, characterized by multiple cytogenetic aberrations on plasma cells (PC) that have been traditionally used to predict the outcome of the disease. A mayor issue on the analysis of PC is the sometimes low infiltration of these cells in the bone marrow that hampers cytogenetic studies. To solve this problem we have optimized a selection strategy based on PC immunomagnetic isolation that has allowed us to lower to 1% the minimal PC infiltration requirement without loss of purity, enabling to perform genetic analysis. In this study, we have analyzed 153 bone marrow samples of patients suspected of MM, collected from February 2015 to May 2017 by the Genetics service of the Complejo Hospitalario de Navarra. Clinical characteristics of the patients and PC immunophenotyping, conventional cytogenetics and interphase fluorescence in situhybridization (iFISH) analyses have been assessed on these samples. In our cohort 90% of the samples had cytogenetic abnormalities, among them 50% presented immunoglobulin rearrangements, 41.9% showed 1q gains, 29.7% showed 1p deletions and 33% presented TP53 deletion.

3. Voriconazole and its clinical potential in the prophylaxis of systemic fungal infection in patients with hematologic malignancies: a perspective review

Author

Zabalza, Amaya, Gorosquieta, Ana, Equiza, Encarnación, and Olavarria, Eduardo

Abstract

Invasive fungal infections (IFIs) have become high prevalence in patients with hematologic malignancies. Drug-based strategies for IFIs include various approaches such as prophylactic, empiric, preemptive, and directed treatment. Prophylaxis is an attractive strategy in high-risk patients, given the lack of reliable diagnostics and the high mortality rate associated with IFIs. Prophylaxis includes the use of antifungal drugs in all patients at risk. An ideal antifungal compound for prophylaxis should have a potent and broad activity, be available both orally and intravenously, and have a low toxicity profile. Voriconazole fulfills all these criteria. The clinical efficacy of voriconazole against the majority of fungal pathogens makes it potentially very useful for the prevention of IFIs in patients with hematologic malignancies. Voriconazole appears to be very effective for the primary and secondary prevention of IFIs in these patients and recipients of allogeneic hematopoietic stem-cell transplantation. Randomized controlled trials evaluating voriconazole as primary antifungal prophylaxis in patients with neutropenia treated for a variety of hematologic malignancies have been performed, confirming its value as a prophylactic agent. Voriconazole is generally safe and well tolerated; however, its use is also associated with a number of concerns. In most patients with hematologic malignancies there is the potential for pharmacokinetic drug–drug interactions given that voriconazole is metabolized through the P450 cytochrome system.

Abstract

Introduction:Allogeneic transplantation is the only curative option for patients with high risk leukemias or MDS. Only one third of them have an HLA identical sibling donor and around 60-70% will find an unrelated donor, that´s why haploidentical stem cell transplantation (HAPLO-HSCT) offers a therapeutic option to most of these patients. Myeloablative conditioning (MAC) produce better disease control than reduced intensity conditioning regimens (RIC), but with higher toxicity, rendering long term similar results.

10. Monitoring Early CMV-Specific CD8+ T-Cell Responses After Allogeneic Stem Cell Transplantation By Pentamer and Streptamer Staining

Author

Beloki, Lorea, Ciaurriz, Miriam, Ramirez, Natalia, Zabalza, Amaya, Mansilla, Cristina, Bandres, Eva, Calvillo, Mercedes Rodriguez, and Olavarría, Eduardo

Abstract

Monitoring CMV-specific-T-cells might be able to distinguish patients at higher risk of recurrent virus reactivation and in need of prolonged antiviral therapy. Patients with increasing CMV-specific-CTLs detectable at the time of CMV-PCR reactivation may only need a short course of antiviral therapy, while those with early CMV-specific-CTLs may be protected from CMV reactivation.Using Multimer-based (Pentamer and Streptamer) monitoring of CMV-specific T-cell immune reconstitution after allogeneic HSCT may contribute to the clinical decision regarding when and for how long to commence anti-CMV therapy.No relevant conflicts of interest to declare.

11. Monitoring Early CMV-Specific CD8+ T-Cell Responses After Allogeneic Stem Cell Transplantation By Pentamer and Streptamer Staining

Author

Abstract

We present the results of a pilot study using pentamer (PM) and streptamer (ST) multimer complexes for monitoring CMV-specific CD8+ T-cells (CTLs). We analysed 15 patients that underwent allogeneic Stem Cell Transplantation (HSCT). Patient characteristics are summarized in Table 1. All patients and donors were positive for the HLA-A*02:01 allele. PM and ST were directed against the epitope NLVPMVATV (495-503) of the CMV phosphoprotein 65 (pp65). Samples were obtained at 15-day intervals until day +90 and monthly thereafter.PatientCMV status (D/R)GenderAgeDiagnosisDonorConditioningEngraftment (day)Follow up (months)GVHD (day)1+/+F43NHLSIBRIC2415-2-/+F33MDSURDRIC1912-3+/+M55AMLSIBMAC1714474-/+F41AMLURDMAC2121-5+/+F32AMLSIBMAC2013256+/+F64MDSSIBRIC2714897-/+M58CLLURDRIC2313928+/+M57ALLURDMAC155-9+/+F39AMLURDMAC2012-10-/+M42ALLURDMAC2125-11-/+M44AMLURDMAC12815312+/+F65AMLSIBRIC258-13-/+M27AMLSIBMAC3031814+/+M65AMLSIBRIC1966215+/-F30SAASIBRIC133-
