Killer-immunoglobulin-like receptors (KIRs) are critical natural killer (NK) cell regulators. The expression of KIRs is a dynamic process influenced by many factors. Their ligands—HLA(Human Leukocyte Antigen) class I molecules—are expressed on all nucleated cells that keep NK cells under control. In hematopoietic stem cell transplantation (HSCT), NK cells play an essential role in relapse protection. In the presented pilot study, we characterized the dynamic expression of inhibitory KIRS (iKIRs), which protect cells against untoward lysis, in donors and patients during the first three months after HSCT using flow cytometry. The expression of all iKIRs was highly variable and sometimes correlated with patients’ clinical presentation and therapy regiment. Cyclophosphamide (Cy) in the graft-versus-host disease (GvHD) prevention protocol downregulated KIR2DL1 to just 25% of the original donor value, and the FEAM (Fludarabine + Etoposid + Ara-C + Melphalan) conditioning protocol reduced KIR2DL3. In lymphoid neoplasms, there was a slightly increased KIR2DL3 expression compared to myeloid malignancies. Additionally, we showed that the ex vivo activation of NK cells did not alter the level of iKIRs. Our study shows the influence of pre- and post-transplantation protocols on iKIR expression on the surface of NK cells and the importance of monitoring their cell surface.

The Impact

Objective: Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is the treatment of choice in patients with Fanconi Anemia (FA). The aim of our study is to evaluate the impact and benefits of allogenic matched donor HSCT in a case of a 12 year-old girl with FA, who displayed good clinical evolution following 2 months post-transplantation. Patients and Methods: In the pre-transplant phase, reference blood samples from the donor and recipient were collected on EDTA. The DNA from blood samples was extracted using an automated Maxwell® 48 RSC instrument (Promega, USA) with the Maxwell® RSC Whole blood DNA kit (Promega, USA). For DNA quantification, the PowerQuant System kit (Promega, USA) was used with the ABI 7500 Real-time PCR system (Applied Biosystems, USA). The amplification of the short tandem repeat markers was performed using the 24plex Investigator QS kit (Qiagen, Germany) on a ProFlex PCR System. Furthermore, the PCR products were separated and detected on an ABI 3500 Genetic Analyzer (Applied Biosytems, USA). Results: After 30 days of the transplantation, a Complete Chimerism (CC) was achieved with a full replacement by donor derived hematopoietic cells. After 60 days of the transplantation, the CC status was maintained with improvement of hematological findings. Conclusion: In FA, chimerism monitoring after HSCT provides useful informations of engraftment or possibility of post-transplantation complications such as graft versus host disease.

Aim: To compare real-world outcomes and costs among patients with newly diagnosed multiple myeloma receiving lenalidomide-only maintenance (Len-Mt) versus no maintenance after autologous hematopoietic stem cell transplantation. Patients & methods: Time to next treatment (TTNT) was evaluated; costs were calculated for 0–12, 12–24 and 24–36 months postindex date. Results: Len-Mt cohort had longer TTNT (HR: 0.43; p < 0.0001). Per-patient per-month costs during months 0–12 were higher among patients, receiving Len-Mt (USD 13,095 vs USD 8910; p < 0.0001), due to higher pharmacy costs – outpatient costs were lower. During months 12–24 and 24–36, outpatient costs were similar in both cohorts; total and pharmacy costs remained elevated for patients receiving Len-Mt. Conclusion: Len-Mt improved TTNT, initially reduced outpatient costs, but resulted in higher overall and pharmacy costs.
