Romiplostim, low-dose rituximab and high-dose dexamethasone for newly diagnosed immune thrombocytopenia: A pilot study.

Therapies such as corticosteroids, thrombopoietin receptor agonists and immunomodulators have been consistently under the spotlight in the search for a better treatment for immune thrombocytopenia (ITP). However, none of them has been widely embraced as a new standard. In this pilot study, we investigated feasibility, safety and preliminary efficacy of romiplostim, low-dose rituximab and high-dose dexamethasone for newly diagnosed ITP.

Reassessing blood product irradiation in haploidentical transplantation: a single-center perspective.

Objectives: The main objective was to investigate the incidence of transfusion-associated graft-versus-host disease (TA-GVHD) in patients who underwent haploidentical hematopoietic cell transplants (HCT) and received non-irradiated leukoreduced blood components. The secondary objective was to describe our leukodepletion results in blood products obtained by the filters employed at our center.

Study Design And Methods: Clinical records from 2018 to 2023 were retrospectively analyzed, along with a prospective evaluation of residual leukocytes in blood components from June to November 2023 in order to confirm effectivity of our leukodepletion method.

Lactate/Pyruvate Ratio as an Early Predictor of Mortality in Patients with Sepsis: A Cohort Study.

: The lactate/pyruvate (LP) ratio has been studied as an alternative to serum lactate to determine clinical prognosis. Despite its clinical utility, there is a paucity of evidence evaluating the role of the L/P ratio in patients with sepsis. : We assessed the clinical utility of the L/P ratio in patients with sepsis.

Outpatient ATG-free hematopoietic transplantation for aplastic anemia in limited-resource environments offers excellent results: Data from a single LATAM center.

Objective: To document the results of outpatient hematopoietic stem cell transplantation (HSCT) from the peripheral blood (PB) of sibling donors without anti-thymocyte globulin (ATG) in the conditioning regimen.

Material And Methods: Patients from a low-income population with severe AA who received a PB, unmanipulated sibling HLA-identical HSCT between 2000 and 2020 at a single institution were studied. Survival was the primary outcome.

Impact of payment source, referral site, and place of residence on outcomes after allogeneic transplantation in Mexico.

Background: The impact of social determinants of health in allogeneic transplant recipients in low- and middle-income countries is poorly described. This observational study analyzes the impact of place of residence, referring institution, and transplant cost coverage (out-of-pocket government-funded private insurance) on outcomes after allogeneic hematopoietic stem cell transplantation (alloHSCT) in two of Mexico's largest public and private institutions.

Aim: To evaluate the impact of social determinants of health and their relationship with outcomes among allogeneic transplant recipients in Mexico.

Increasing access to transplantation through telemedicine and patient navigation.

Background: Hematopoietic cell transplantation (HCT) is a promising treatment for hematological diseases, yet access barriers like cost and limited transplant centers persist. Telemedicine-based patient navigation (PN) has emerged as a solution. This study presents a cost-free PN telemedicine clinic (TC) in collaboration with the National Marrow Donor Program.

Point of care thoracic ultrasound versus chest computed tomography in the approach of febrile neutropenia patients: A diagnostic accuracy cohort study.

Single-center prospective cohort diagnostic accuracy study. Our study aimed to evaluate the accuracy and reproducibility of Thoracic Ultrasound (TUS) in detecting pulmonary pathology in immunosuppressed patients. We conducted a single-center prospective study.

Graft-versus-host disease after an outpatient peripheral blood hematopoietic cell transplant using reduced-intensity conditioning: a single-center LATAM experience.

Background: HLA compatibility predicts allogeneic hematopoietic cell transplant (allo-HCT) and graft-versus-host disease (GvHD) outcomes. There is insufficient information regarding GvHD outcomes for outpatient HLA-identical and haploidentical-HCT employing reduced-intensity conditioning (RIC).

Research Design And Methods: We compare GvHD outcomes between donor types and report risk factors associated with GvHD.

Long-Term Efficacy of High-Dose Imatinib in Hispanic Patients Without Access to Second-Generation Tyrosine Kinase Inhibitors Treated in LATAM Centers.

Background: While second-generation tyrosine kinase inhibitors (TKI) revolutionized treatment for patients with chronic myeloid leukemia (CML) who developed a suboptimal response to imatinib, many patients in developing countries are fixed to the latter due to socioeconomic barriers. Despite this scenario, scarce information is available to evaluate the clinical prognosis of these patients.

Methods: We conducted a retrospective cohort analysis to compare the overall mortality of patients with CML who developed a suboptimal response to a standard dose of imatinib and were treated with either high-dose imatinib or a second-generation TKI.

Infection-related mortality after HLA-identical and haploidentical hematopoietic cell transplantation using reduced-intensity conditioning in an outpatient setting.

Background: Despite the improvements in supportive care for allogeneic-hematopoietic cell transplantation (allo-HCT) recipients, infectious complications and infection-related mortality (IRM) continue to be a major issue for transplantation centers.

Methods: We herein report the infectious complications and IRM of 107 and 89 patients that underwent haploidentical (haplo-HCT) or HLA-identical HCT at a tertiary referral center during 2013-2020. Patients in the haplo-HCT group received post-transplant cyclophosphamide (PT-Cy), and all received reduced-intensity conditioning regimens.

Intermittent Soft-Tissue Tumor Enlargement in Episodic Angioedema With Eosinophilia Syndrome.

Episodic hypereosinophilia and angioedema syndrome, also known as Gleich syndrome, is a rare entity characterized by recurrent episodes of eosinophilia, angioedema, urticaria, fever and weight gain with spontaneous resolution. It is classified as an idiopathic hypereosinophilic syndrome. Unlike other hypereosinophilic syndromes, it has a low risk for internal organ damage.

Treatment of Ph-Negative Acute Lymphoblastic Leukemia in Adolescents and Young Adults with an Affordable Outpatient Pediatric Regimen.

Background: B-cell acute lymphoblastic leukemia is frequent in Hispanic adolescents and young adults. Outcomes of implementation of pediatric-inspired regimens in low-and middle-income countries are not well known.

Methods: In this study we treated 94 adolescents and young adults with a local BFM regimen designed to be affordable with the use of native L-asparaginase and mitoxantrone administered in an outpatient fashion, and the of BCR/ABL and measurable residual disease (MRD) determined by high sensitivity flow cytometry for risk stratification.

Oseltamivir as rescue therapy for persistent, chronic, or refractory immune thrombocytopenia: a case series and review of the literature.

Immune thrombocytopenia (ITP) is an autoimmune disease that results from antibody-mediated platelet destruction and impaired platelet production. Novel therapies have emerged in the last decade, but 15-20% of patients will relapse or fail and require further therapy. We performed a prospective, single-arm intervention study on seven patients with chronic, persistent, or refractory ITP from the Hospital Universitario "Dr.

Outpatient allogeneic hematopoietic stem-cell transplantation: a review.

Hematopoietic stem-cell transplantation (HSCT) is usually performed in well-equipped units inside a hospital. The cost of this in-hospital transplant is usually very high; therefore, this procedure is more difficult to perform in low- and middle-income countries. Autologous outpatient HSCT is now a common procedure; however, outpatient allogeneic transplants are more complicated.

Autologous ATG-free hematopoietic stem cell transplantation for refractory autoimmune rheumatic diseases: a Latin American cohort.

Autologous hematopoietic stem cell transplantation (HSCT) has been recognized as treatment alternative for patients with severe, refractory autoimmune rheumatic diseases (ARDs). Usually, anti-thymocyte globulin (ATG)-containing conditioning regimens are employed; however, ATG is unavailable in some developing nations. We report our 15-year clinical experience autografting patients with ARDs with an ATG-free conditioning regimen and a brief assessment of patient-reported outcomes post-HSCT.

Performance of serum procalcitonin as a biochemical predictor of death in hematology patients with febrile neutropenia.

Introduction: Historically, the measurement of serum procalcitonin (PCT) levels in patients with leukopenia has been rejected without sufficient prospective evidence to justify this argument. On the other hand, the accumulated use of broad spectrum antibiotics in these patients and their consequences make the use of PCT attractive in an effort to reduce its use.

Patients And Methods: We conducted a prospective study between 2016 and 2018, recruiting newly diagnosed FN patients, evaluating them with PCT levels during the first 24 h.

Moral Distress: Its Manifestations in Healthy Donors during Peripheral Blood Hematopoietic Stem Cell Harvesting.

Hematopoietic stem cell donors (HSCDs) may have ambivalent feelings about donation. These feelings are related to moral obligation to help a sick relative and/or fear about the donation procedure. This ambivalence can produce moral distress (MD) and anxiety, which are usually unnoticed by the treating physician.
