Guidelines for the diagnosis and treatment of chronic lymphocytic leukemia and small lymphocytic lymphoma from Chronic Lymphocytic Leukemia Spanish Group (GELLC).

Introduction: Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in adults in Western countries, with a median age at diagnosis of 72 years. This guide, developed by the Spanish Group for Chronic Lymphocytic Leukemia (GELLC), addresses the most relevant aspects of CLL, with the objectives of facilitating and aiding the diagnostic process, establishing therapeutic recommendations for choosing the best treatment for each type of patient, as well as standardizing the management of CLL and ensuring equity across different hospitals in terms of the use of the various available treatment regimens.

Methodology: The references obtained were classified according to the level of evidence and following the criteria established by the Agency for Health Research and Quality, and the recommendations were classified according to the criteria of the National Comprehensive Cancer Network (NCCN).

Holding the therapy in CLLp53: mechanisms to achieve durable responses.

Chronic lymphocytic leukemia (CLL) is a common leukemia, mainly affecting the elderly. Originating in the bone marrow, CLL involves the accumulation of B lymphocytes and progresses slowly, though 50-60% of patients will require therapy. At diagnosis, the presence of p53 protein aberrations, such as 17p deletion and TP53 mutation, arises in approximately one out of 10 patients.

Real-World Experience with Isavuconazole in Allogeneic Stem Cell Transplantation in Spain.

Invasive fungal infections (IFI) pose a significant complication after hematopoietic stem cell transplantation (HSCT). Isavuconazole (ISV) is a new generation azole with a favourable adverse effect and interaction profile approved for the treatment of invasive aspergillosis and mucormycosis. We analyzed the indications, effectiveness, adverse event profile and drug interaction management of ISV in the real-world setting in adults who received allogeneic-HSCT (allo-HSCT) within the Spanish Group of HSCT and Cell Therapy (GETH-TC).

Ibrutinib followed by ofatumumab consolidation in previously untreated patients with chronic lymphocytic leukemia (CLL): GELLC-7 trial from the Spanish group of CLL (GELLC).

Background: BTK inhibitors have been concurrently administered with anti-CD20 monoclonal antibodies (mAbs) in chronic lymphocytic leukemia (CLL). However, the optimal regimen for combining these two drugs remains pending.

Methods: This multi-center phase 2 study aimed to analyze whether consolidation with ofatumumab improved the response in patients with CLL receiving front-line treatment with ibrutinib.

Bloodstream Infections Presenting with Septic Shock in Neutropenic Cancer Patients: Impact of Empirical Antibiotic Therapy.

This large, multicenter, retrospective cohort study including onco-hematological neutropenic patients with bloodstream infection (PABSI) found that among 1213 episodes, 411 (33%) presented with septic shock. The presence of solid tumors (33.3% vs.

Co-Culture of . and . Synergistically Elevates IL-6 Expression via TLR4 Signaling in Oral Keratinocytes.

Periodontitis, characterized by persistent inflammation in the periodontium, is intricately connected to systemic diseases, including oral cancer. Bacteria, such as and , play a pivotal role in periodontitis development because they contribute to dysbiosis and tissue destruction. Thus, comprehending the interplay between these bacteria and their impacts on inflammation holds significant relevance in clinical understanding and treatment advancement.

Critical Limb Ischaemia in Octogenarians: Treatment Outcomes Compared With Younger Patients.

Objective: A growing proportion of patients with chronic limb threatening ischaemia (CLTI) are elderly, the most challenging for management decisions. The aim was to study the patient profile and outcome of CLTI in octogenarian patients, comparing them with younger patients.

Methods: Retrospective cohort of consecutive patients hospitalised for CLTI with infrainguinal disease in a Spanish centre (2013-2020).

Breakthrough invasive fungal infection among patients with haematologic malignancies: A national, prospective, and multicentre study.

Objectives: We describe the current epidemiology, causes, and outcomes of breakthrough invasive fungal infections (BtIFI) in patients with haematologic malignancies.

Methods: BtIFI in patients with ≥ 7 days of prior antifungals were prospectively diagnosed (36 months across 13 Spanish hospitals) according to revised EORTC/MSG definitions.

Results: 121 episodes of BtIFI were documented, of which 41 (33.

Recommendations on the use of azole antifungals in hematology-oncology patients.

The administration of antifungals for therapeutic and, especially, prophylactic purposes is virtually a constant in patients requiring hematology-oncology treatment. Any attempt to prevent or treat Aspergillus or Mucor infections requires the administration of some drugs in the azole group, which include voriconazole, posaconazole and isavuconazole, noted for their activity against these pathogens. One very relevant aspect is the potential risk of interaction when associated with one of the antineoplastic drugs used to treat hematologic tumors, with serious complications.

Role of allogeneic hematopoietic cell transplant for relapsed/refractory aggressive B-cell lymphomas in the CART era.

Anti-CD19 chimeric antigen receptor T cells (CART) has rapidly been adopted as the standard third-line therapy to treat aggressive B-cell lymphomas (ABCL) after failure of second-line therapy despite the lack of direct comparisons with allogeneic hematopoietic cell transplantation (alloHCT)-based strategies. Using the Grupo Español de Trasplante y Terapia Celular (GETH-TC) registry, we selected patients with the following characteristics: CART or alloHCT performed between 2016 and 2021; ≥18 years old; ABCL diagnosis; ≥2 lines of therapy; and either anti-CD19 CART or alloHCT as therapy at relapse. The analysis included a total of 316 (CART = 215, alloHCT = 101) patients.

High Prevalence of Infection in Dairy Cattle with Chronic Mastitis in Ecuador.

The genus , a unicellular, non-photosynthetic, yeast-like microalgae, is a pathogen of concern for the dairy industry. It causes bovine mastitis that currently cannot be cured, and hence generates significant economic losses in milk production. In this study, for the first time in Ecuador, we identify as the etiologic agent of chronic mastitis in dairy cattle.

Low Rate of Infectious Enterocolitis in Allogeneic Stem Cell Transplant Recipients with Acute Diarrhea: A Prospective Study by the GETH-TC.

Acute diarrhea is a common and debilitating complication in recipients of allogeneic hematopoietic stem cell transplantation (HCT). In this prospective, observational, and multicenter study we examined all episodes occurring in the first 6 months of 142 consecutive adult patients who underwent a reduced-intensity conditioning HCT in 10 Spanish tertiary university hospitals. Fifty-four patients (38%) developed a total of 75 acute diarrhea episodes.

Feasibility of a Hospital-at-Home Program for Autologous Hematopoietic Stem Cell Transplantation.

The Hospital at Home (HaH) model has been positioned as an appropriate therapeutic strategy for selected patients undergoing autologous hematopoietic stem cell transplantation (ASCT). This care model provides hospital-equivalent care, in terms of both quality and quantity, with medical and nursing staff that go to the patient's home. Here we describe our experience with a full HaH model for patients undergoing ASCT during the phase of aplasia.

Allogeneic Hematopoietic Stem Cell Transplantation in Transformed Follicular Lymphoma (tFL): Results of a Retrospective Multicenter Study from GELTAMO/GETH-TC Spanish Groups.

Background: Transformation of follicular lymphoma into an aggressive lymphoma (tFL) worsens the prognosis and the standard treatment is not completely defined. Allogeneic hematopoietic stem cell transplantation (alloSCT) could be a potentially curative option for these patients, but it has not been widely explored.

Methods: We designed a retrospective multicenter study to analyze the efficacy and toxicity of alloSCT in tFL patients and potential prognostic factors of survival.
