Early Post-Transplant Torquetenovirus Viremia Predicts Cytomegalovirus Reactivations In Solid Organ Transplant Recipients.
2018
AbstractMonitoring the human virome has been recently suggested as a promising and novel area of research for identifying new biomarkers which would help physicians in the management of transplant patients. Imbalance of the immune system in transplant recipients has a significant impact on replication of Torquetenovirus (TTV), the most representative and abundant virus of human virome. TTV kinetic was studied by real-time PCR in 280 liver or kidney transplant recipients who underwent different drug regimens to maintain immunosuppression. During one-year post-transplant follow-up, TTV viremia fluctuated irrespective of transplanted organ type but consistent with the immunosuppression regimen…
Vγ9Vδ2 T Cells in the Bone Marrow of Myeloma Patients: A Paradigm of Microenvironment-Induced Immune Suppression
2018
Vγ9Vδ2 T cells are non-conventional T cells with a natural inclination to recognize and kill cancer cells. Malignant B cells, including myeloma cells, are privileged targets of Vγ9Vδ2 T cells in vitro. However, this inclination is often lost in vivo due to multiple mechanisms mediated by tumor cells and local microenvironment. Multiple myeloma (MM) is a paradigm disease in which antitumor immunity is selectively impaired at the tumor site. By interrogating the immune reactivity of bone marrow (BM) Vγ9Vδ2 T cells to phosphoantigens, we have revealed a very early and long-lasting impairment of Vγ9Vδ2 T-cell immune functions which is already detectable in monoclonal gammopathy of undetermined …
Prognosis of patients with primary central nervous system lymphoma after high-dose chemotherapy followed by autologous stem cell transplantation
2013
High-dose chemotherapy followed by autologous stem cell transplantation has been shown to be feasible and highly effective in newly diagnosed primary central nervous system lymphoma. In this retrospective multicenter study, we investigated prognosis and baseline risk factors in patients with primary central nervous system lymphoma who underwent this treatment approach. We retrospectively analyzed 105 immunocompetent patients with primary central nervous system lymphoma who underwent high-dose chemotherapy followed by autologous stem cell transplantation with or without whole brain radiotherapy as first-line consolidation treated at 12 German centers between 1997 and 2011. We estimated survi…
Improved relapse-free survival after autologous stem cell transplantation does not translate into better quality of life in chronic lymphocytic leuke…
2014
Item does not contain fulltext In chronic lymphocytic leukemia (CLL) medical progress is driven by clinical studies with relapse-free survival (RFS) as the primary endpoint. The randomized EBMT-Intergroup trial compared high-dose therapy and autologous stem cell transplantation (ASCT) to observation and demonstrated a substantial improvement of RFS without showing improved overall survival for the transplant arm. Here we report quality of life (QoL) information of the first 3 years following randomization from that study. The main objective was to assess the impact of treatment on QoL over time. Two secondary analyses were performed to further investigate the impact of ASCT and relapse on Q…
Voriconazole versus itraconazole for antifungal prophylaxis following allogeneic haematopoietic stem‐cell transplantation
2011
Antifungal prophylaxis for allogeneic haematopoietic stem-cell transplant (alloHCT) recipients should prevent invasive mould and yeast infections (IFIs) and be well tolerated. This prospective, randomized, open-label, multicentre study compared the efficacy and safety of voriconazole (234 patients) versus itraconazole (255 patients) in alloHCT recipients. The primary composite endpoint, success of prophylaxis, incorporated ability to tolerate study drug for ≥100 d (with ≤14 d interruption) with survival to day 180 without proven/probable IFI. Success of prophylaxis was significantly higher with voriconazole than itraconazole (48·7% vs. 33·2%, P 10%) treatment-related adverse events were vom…

Genetics and novel aspects of therapies in systemic lupus erythematosus.
2015
Autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, autoimmune hepatitis and inflammatory bowel disease, have complex pathogeneses and the factors which cause these disorders are not well understood. But all have in common that they arise from a dysfunction of the immune system, interpreting self components as foreign antigens. Systemic lupus erythematosus (SLE) is one of these complex inflammatory disorders that mainly affects women and can lead to inflammation and severe damage of virtually any tissue and organ. Recently, the application of advanced techniques of genome-wide scanning revealed more genetic information about SLE than previously possible. These case-contro…
Allogeneic Stem Cell Transplantation in Mantle Cell Lymphoma; Insights into Its Potential Role in the Era of New Immunotherapeutic and Targeted Thera…
2022
Simple Summary We present the long-term results of patients receiving allogeneic stem cell transplantation (allo-SCT) for relapsed/refractory mantle cell lymphoma (R/R MCL) in the last 25 years in Spain. We conclude that allo-SCT may be a curative option in R/R MCL with a low cumulative incidence (CI) of relapse, although non-relapse mortality (NRM) is still high, which is mainly secondary to acute graft-versus-host disease (aGVHD). Results are better for fit patients, using HLA-identical (related or unrelated) or haploidentical related donors and without previous ASCT. However, the arrival of new highly effective and low toxic immunotherapeutic or targeted therapies inevitably will relegat…
Recent Advances in the Treatment of Patients with Multiple Myeloma
2020
Simple Summary The evolving data from trials assessing novel combinations as a part of the frontline and relapse treatment in transplant and non-transplant candidates have markedly improved the anti-myeloma efficacy of the different therapeutic regimens and improved patients’ prognosis. Current treatment objectives are focused to further improve the rate of complete remission, time to progression, progression-free survival and overall survival without increasing toxicity. Besides, different strategies are being developed in the elderly population as this group of patients requires a closer monitoring with individualized, dose-modified regimens to improve tolerability while maintaining their…
Targeting multiple myeloma with natural polyphenols
2019
Multiple myeloma (MM) is still an incurable hematologic malignancy. Although new therapeutic strategies have been developed to target different pathways in malignant cells, such as proliferation, differentiation, and apoptosis, better survival rates have also been achieved by the introduction of autologous stem cell transplantation (ASCT). Hematopoietic stem cell transplantation and novel targeted agents, such as proteasome inhibitors, monoclonal antibodies, immunomodulatory drugs, check-point inhibitors and epigenetic modulators, have significantly achieved long remission time and increased survival rates. However, most patients relapse, develop resistance, and eventually die because of re…
