Patients Age 40 Years and Younger With Multiple Myeloma Have the Same Prognosis as Older Patients: An Analysis of Real-World Patients' Evidence From Latin America.

PURPOSE: Multiple myeloma (MM) is a highly heterogeneous, incurable disease most frequently diagnosed in the elderly. Therefore, data on clinical characteristics and outcomes in the very young population are scarce. PATIENTS AND METHODS: We analyzed clinical characteristics, response to treatment, and survival in 103 patients with newly diagnosed MM age 40 years or younger compared with 256 patients age 41-50 years and 957 patients age 51 years or older. RESULTS: There were no statistical differences in sex, isotype, International Scoring System, renal involvement, hypercalcemia, anemia, dialysis, bony lesions, extramedullary disease, and lactate dehydrogenase (LDH). The most used regimen in young patients was cyclophosphamide, bortezomib, dexamethasone, followed by cyclophosphamide, thalidomide, dexamethasone and bortezomib, thalidomide, dexamethasone. Of the patients age 40 years or younger, only 53% received autologous stem-cell transplant (ASCT) and 71.1% received maintenance. There were no differences in overall survival (OS) in the three patient cohorts. In the multivariate analysis, only high LDH, high cytogenetic risk, and ASCT were statistically associated with survival. CONCLUSION: In conclusion, younger patients with MM in Latin America have similar clinical characteristics, responses, and OS compared with the elderly.

Letermovir para prevención de la infección por citomegalovirus en receptores de trasplante alogénico de progenitores hematopoyéticos

Introducción: La infección por citomegalovirus (CMV) sigue siendo la infección con relevancia clínica más frecuente luego del trasplante alogénico de progenitores hematopoyéticos (TPHa), presentando alta morbilidad y mortalidad. Por este motivo, es importante implementar estrategias de prevención para reducir la frecuencia de la infección por CMV. Objetivo: Describir la frecuencia de infección, infección clínicamente significativa (ICS) y enfermedad por CMV en pacientes seropositivos que recibieron un TPHa y profilaxis primaria con letermovir. Pacientes y Métodos: Estudio descriptivo de cohorte longitudinal, en pacientes con TPHa seropositivos para CMV que recibieron profilaxis primaria con letermovir hasta el día 100 posTPH. Resultados: Se incluyeron 25 pacientes adultos con una mediana de edad de 41 años, el 44% fue de donante no relacionado y 36% de donante haploidéntico. Ochenta por ciento tenía tres o más factores de riesgo para infección por CMV y a 52% se le estratificó como de alto riesgo para enfermedad por CMV. La profilaxis con letermovir tuvo una mediana de duración de 97 días. Durante los 100 días pos-TPH, 20% de los pacientes presentaron infección por CMV, con carga viral plasmática detectable no cuantificable, que se negativizó en el siguiente control semanal sin discontinuación del letermovir. Ningún paciente presentó ICS ni enfermedad por CMV durante este período. Conclusión: La profilaxis con letermovir fue efectiva para prevenir la ICS y la enfermedad por CMV.

Background: Cytomegalovirus (CMV) infection remains the most common clinically significant infection after allogeneic stem cell transplantation (aSCT), with a high morbidity and mortality rate. In order to reduce its frequency, prevention strategies should be implemented. Aim: To describe the frequency of infection, clinically significant infection (CSI) and CMV disease in seropositive patients who received aSCT and primary prophylaxis with letermovir. Methods: Longitudinal descriptive cohort study in seropositive patients who received aSCT and primary prophylaxis with letermovir until day 100 post-SCT. Results: Twenty-five adult patients with a median age of 41 years were included; 44% were unrelated donors, and 36% were haploidentical donors. Eighty percent had three or more risk factors for CMV infection, and 52% were stratified as high risk for CMV disease. Letermovir prophylaxis had a median duration of 97 days. Twenty percent of the patients developed CMV infection through day 100 post-SCT, with detectable non-quantifiable CMV viral load in plasma. This became negative in the following weekly control without discontinuation of letermovir. No patient developed CSI or CMV organ disease during this period. Conclusion: Letermovir prophylaxis proved to be effective in preventing CSI and CMV disease.

Primary plasma cell leukemia in Latin America: demographic, clinical, and prognostic characteristics. A study of GELAMM group.

Primary plasma cell leukemia (pPCL) is an infrequent and aggressive plasma cell disorder. The prognosis is still very poor, and the optimal treatment remains to be established. A retrospective, multicentric, international observational study was performed. Patients from 9 countries of Latin America (LATAM) with a diagnosis of pPCL between 2012 and 2020 were included. 72 patients were included. Treatment was based on thalidomide in 15%, proteasome inhibitors (PI)-based triplets in 38% and chemotherapy plus IMIDs and/or PI in 29%. The mortality rate at 3 months was 30%. The median overall survival (OS) was 18 months. In the multivariate analysis, frontline PI-based triplets, chemotherapy plus IMIDs and/or PI therapy, and maintenance were independent factors of better OS. In conclusion, the OS of pPCL is still poor in LATAM, with high early mortality. PI triplets, chemotherapy plus IMIDs, and/or PI and maintenance therapy were associated with improved survival.

Treatment and Survival Outcomes of Waldenstrom Macroglobulinemia in Latin American Patients: A Multinational Retrospective Cohort Study.

PURPOSE: Waldenstrom Macroglobulinemia (WM) is a rare lymphoma with distinct clinical features, and data from Latin American patients are lacking. Therefore, we aim to investigate the clinical, therapy, and outcome patterns of WM in Latin America. METHODS: We retrospectively analyzed patients with WM diagnosed between 1991 and 2019 from 24 centers in seven Latin American countries. The study outcomes were overall survival (OS) and progression-free survival (PFS). RESULTS: We identified 159 cases (median age 67 years, male 62%). Most patients (95%) were symptomatic at diagnosis. The International Prognostic Scoring System for WM (IPSSWM) at diagnosis was available in 141 (89%) patients (high-risk 40%, intermediate-risk 37%, and low-risk 23%). Twenty-seven (17%) patients were tested for MYD88L265P, with 89% (n = 24 of 27) carrying the mutation. First-line and second-line therapies were administered to 142 (89%) and 53 (33%) patients, respectively. Chemoimmunotherapy was the most commonly used first-line (66%) and second-line (45%) approach; only 18 (11%) patients received ibrutinib. With a median follow-up of 69 months, the 5-year OS rate was 81%. In treated patients, the 5-year OS and PFS rates were 78% and 59%, respectively. High-risk IPSSWM at treatment initiation was an independent risk factor for OS (adjusted hazard ratio: 4.73, 95% CI, 1.67 to 13.41, P = .003) and PFS (adjusted hazard ratio: 2.43, 95% CI, 1.31 to 4.50, P = .005). CONCLUSION: In Latin America, the management of WM is heterogeneous, with limited access to molecular testing and novel agents. However, outcomes were similar to those reported internationally. We validated the IPSSWM score as a prognostic factor for OS and PFS. There is an unmet need to improve access to recommended diagnostic approaches and therapies in Latin America.

Real-world outcomes for the treatment of relapsed/refractory multiple myeloma patients with lenalidomide-dexamethasone combinations in a Latin American country. A retrospective cohort study from grupo argentino de mieloma múltiple.

OBJECTIVES: We compared the efficacy of lenalidomide-dexamethasone (Rd) based treatments for relapsed/refractory multiple myeloma patients (pts), in a real-world setting. In addition, we evaluated adverse events (AE), progression-free survival (PFS) and overall survival (OS). METHODS: In our retrospective, multicentric study, 156 pts with RRMM were included. 74/156 pts (47%) were refractory to bortezomib (V) and 43/156 (27%) pts to lenalidomide (R), with 24/156 (15%) of pts double refractory. Eighty-six pts (55%) received Rd with carfilzomib (KRd), 30 pts (19%) bortezomib (VRd), 30 pts (19%) daratumumab (DRd), and 10 pts (6%) ixazomib (IRd). RESULTS: The overall response (ORR) (≥ partial response) for the entire cohort was 71%, with a very good partial response rate or better (≥VGPR) of 35%. We found no significant differences in CR or ≥VGRP rates between treatments (p:0.229). Regardless of the combination received, those patients who achieved CR had significantly improved PFS (p: 0.007). The most frequent cause of treatment discontinuation was disease progression in 55/156 pts (35%). 8 pts (5%) discontinued treatment due to treatment-related adverse events (AE). CONCLUSION: This is the first report of Rd combinations for the treatment of RRMM in Latin America. All combinations proved to be effective with an acceptable toxicity.

Different outcomes for transplant-eligible newly diagnosed multiple myeloma patients in Latin America according to the public versus private management: a GELAMM study.

The aim of this study was to describe clinical and survival characteristics of transplant-eligible multiple myeloma (MM) patients in Latin America (LA), with a special focus on differences between public and private healthcare facilities. We included 1293 patients diagnosed between 2010 and 2018. A great disparity in outcomes and survival between both groups was observed. Late diagnosis and low access to adequate frontline therapy and ASCT in public institutions probably explain these differences. Patients treated with novel drug induction protocols, followed by autologous stem cell transplantation (ASCT) and maintenance, have similar overall survival compared to that published internationally.

Abstract The coronavirus disease 2019 (COVID-19) pandemic requires rapid medical responses. The risk of venous and arterial thromboembolism increases in critically ill patients with SARS-CoV-2 infection. There is a hypercoagulable state that includes elevated levels of D-dimer, with an increased risk of organ failure and increased mortality. The abnormalities described in hemostasis should be considered for therapeutic decision making. We analyzed the available scientific evidence for the therapeutic approach of coagulopathy in the course of the disease with the objective of designing realistic therapeutic recommendations aimed at reducing morbidity and mortality in patients with COVID-19.

Predicting Mortality after Autologous Transplant: Development of a Novel Risk Score.

There have been several efforts to predict mortality after autologous stem cell transplantation (ASCT), such as the hematopoietic cell transplant-comorbidity index (HCT-CI), described for allogeneic stem cell transplantation and validated for ASCT, but there is no composite score in the setting of ASCT combining comorbidities with other clinical characteristics. Our aim is to describe a comprehensive score combining comorbidities with other clinical factors and to analyze the impact of this score on nonrelapse mortality (NRM), overall survival (OS), and early morbidity endpoints (mechanical ventilation, shock or dialysis) after ASCT. For the training cohort, we retrospectively reviewed data of 2068 adult patients who received an ASCT in Argentina (October 2002 to June 2017) for multiple myeloma or lymphoma. For the validation cohort, we analyzed 2168 ASCTs performed in the Medical College of Wisconsin and Spanish stem cell transplant group (Grupo Español de Trasplante Hematopoyético (GETH)) (January 2012 to December 2018). We first performed a multivariate analysis for NRM in order to select and assign weight to the risk factors included in the score (male patients, aged 55 to 64 and ≥65 years, HCT-CI ≥3, Hodgkin lymphoma and non-Hodgkin lymphoma). The hazard ratio for NRM increased proportionally with the score. Patients were grouped as low risk (LR) with a score of 0 to 1 (686, 33%), intermediate risk (IR) with a score of 2 to 3 (1109, 53%), high risk (HR) with a score of 4 (198, 10%), and very high risk (VHR) with a score of ≥5 (75, 4%). The score was associated with a progressive increase in all the early morbidity endpoints. Moreover, the score was significantly associated with early NRM (day 100: 1.5% versus 2.4% versus 7.6% versus 17.6%) as well as long term (1 to 3 years; 1.8% to 2.3% versus 3.8% to 4.9% versus 11.7% to 14.5% versus 25.0% to 27.4%, respectively; P< .0001) and OS (1 to 5 years; 94% to 73% versus 89% to 75% versus 76% to 47% versus 65% to 52% respectively; P < .0001). The score was validated in an independent cohort (N = 2168) and was significantly associated with early and late events. In conclusion, we developed and validated a novel score predicting NRM and OS in 2 large cohorts of more than 2000 autologous transplant patients. This tool can be useful for tailoring conditioning regimens or defining risk for transplant program decision making.

Real world outcomes with Bortezomib Thalidomide dexamethasone and Cyclophosphamide Bortezomib dexamethasone induction treatment for transplant eligible multiple myeloma patients in a Latin American country. A Retrospective Cohort Study from Grupo Argentino de Mieloma Múltiple.

Data about treatment outcomes and toxicity in Latin America are scarce. There are differences with central countries based on access to healthcare system and socioeconomic status. Argentinean Society of Hematology recommends bortezomib-based triplets for induction treatment of transplant eligible newly diagnosed multiple myeloma patients. Most common options are CyBorD (cyclophosphamide, bortezomib and dexamethasone) and VTD (bortezomib, thalidomide and dexamethasone). Main goal of our retrospective, multicentric study was to compare very good partial response rate (VGPR) or better after induction treatment in a real-world setting in Argentina. Secondary objectives included comparison of complete response (CR) post-induction and after bone marrow transplantation, grade 3-4 adverse events (AEs), progression-free survival (PFS) and overall survival (OS). Three hundred twenty-two patients were included (median age at diagnosis: 57 years; 52% male; 28% had ISS3; 14% with high-risk cytogenetics; median follow up: 34 months). CyBorD was indicated in 74% and 26% received VTD. In VTD arm, 72.62% of patients achieved at least VGPR vs 53.36% receiving CyBorD (odds ratio, OR: 1.96 [95% confidence interval, CI: 1.08-3.57; P = .026] after adjusting by age, ISS [International Staging System], lactate dehydrogenase levels (LDH) and cytogenetic risk. Difference in VGPR was 19.26% (95% CI: 15-24). CR rate were 35.92% (VTD) vs 22.55% (CyBorD) (adjusted OR: 2.13 [95% CI: 1.12-4.05]). Difference in CR was 13.37% (95% CI: 9.6-17.53). Adverse events (AEs) were more common with VTD (69.05% vs 55.46% for CyBorD; P = .030), especially grade 3-4 neuropathy (P = .005) and thrombosis (P = .001). Thromboprophylaxis was inadequate in 20.24% of patients. Hematological AEs were more common with CyBorD, especially thrombocytopenia (P = .017). PFS and OS at 24 months were not different between treatments. In this real-world setting, VTD was associated with better CR and VGPR than CyBorD. Nevertheless, CyBorD continues to be the preferred induction regimen in Argentina, based on safety profile. Frontline autologous stem cell transplantation improves quality of responses, especially in countries with limited access to new drugs.

Haploidentical transplant in adult patients with acute lymphoblastic leukemia in Argentina: a comparison with matched related and unrelated donors.

We aimed at analyzing the outcome of allogeneic stem cell transplant (ASCT) in adult patients with acute lymphoblastic leukemia (ALL), comparing Haploidentical (Haplo) with HLA-matched (sibling and unrelated) donors. Between 2008 and 2017, we collected data from 236 patients (median age 31 years; range 16-64; 90% HCT-CI 0-1) who underwent unmanipulated ASCT in first complete remission and subsequent remissions in 15 Argentinian centers. Donors were HLA-matched (n = 175; 74%) and Haplo (n = 61; 26%). Two-year overall survival (OS) was 55% (95% CI 47-63) for the HLA-matched group and 49% (95% CI 34-62) for the Haplo group (p = 0.351). For OS, crude HR, adjusted HR for covariates (HR 1.24; 95% CI 0.77-1.99; p = 0.363) and HR including a propensity score in the model (HR 1.22; 95% CI 0.71-2.08; p = 0.414) showed no impact of donor category on the OS. No difference was found in terms of nonrelapse mortality, relapse, leukemia-free survival, and grade 3-4 acute graft-versus-host disease (GVHD); 2-year incidence of chronic GVHD was higher in HLA-matched vs Haplo group (p = 0.028). Patients with ALL who underwent ASCT were young subjects with low HCT-CI. In this setting, a Haplo donor represents an alternative widely available in the absence of an HLA-matched donor. Relapse remains a challenge for all donor categories.

Intravenous iron reduces NT-pro-brain natriuretic peptide in anemic patients with chronic heart failure and renal insufficiency.

OBJECTIVES: Our objective was to evaluate in a double-blind, randomized, placebo-controlled study possible modifications in NT-pro-brain natriuretic peptide (NT-proBNP) and C-reactive protein (CRP) levels together with clinical and functional parameters, in a group of anemic patients with chronic heart failure (CHF) and chronic renal failure (CRF) receiving intravenous iron therapy, without recombinant human erythropoietin (rhEPO), versus placebo. BACKGROUND: Chronic heart failure and CRF associated with absolute or relative iron deficiency anemia is a common problem. This situation is linked with a variable inflammatory status. Both NT-proBNP and CRP are recognized markers for left ventricular dysfunction and inflammatory status, respectively. In this double-blind, randomized, placebo-controlled study, modifications in NT-proBNP and CRP level and clinical and functional parameters, in anemic patients with CHF and CRF receiving intravenous iron therapy, without rhEPO, versus placebo were evaluated. METHODS: Forty patients with hemoglobin (Hb) <12.5 g/dl, transferrin saturation <20%, ferritin <100 ng/ml, creatinine clearance (CrCl) <90 ml/min, and left ventricular ejection fraction (LVEF) < or =35% were randomized into 2 groups (n = 20 for each). For 5 weeks, group A received isotonic saline solution and group B received iron sucrose complex, 200 mg weekly. Minnesota Living with Heart Failure Questionnaire (MLHFQ) and 6-min walk (6MW) test were performed. NT-pro brain natriuretic peptide and CRP were evaluated throughout the study. No patients received erythroprotein any time. RESULTS: After 6 months follow-up, group B showed better hematology values and CrCl (p < 0.01) and lower NT-proBNP (117.5 +/- 87.4 pg/ml vs. 450.9 +/- 248.8 pg/ml, p < 0.01) and CRP (2.3 +/- 0.8 mg/l vs. 6.5 +/- 3.7 mg/l, p < 0.01). There was a correlation initially (p < 0.01) between Hb and NT-proBNP (group A: r = -0.94 and group B: r = -0.81) and after 6 months only in group A: r = -0.80. Similar correlations were observed with Hb and CRP. Left ventricular ejection fraction percentage (35.7 +/- 4.7 vs. 28.8 +/- 2.4), MLHFQ score, and 6MW test were all improved in group B (p < 0.01). Additionally, group B had fewer hospitalizations: 0 of 20 versus group A, 5 of 20 (p < 0.01; relative risk = 2.33). CONCLUSIONS: Intravenous iron therapy without rhEPO substantially reduced NT-proBNP and inflammatory status in anemic patients with CHF and moderate CRF. This situation was associated with an improvement in LVEF, NYHA functional class, exercise capacity, renal function, and better quality of life.

Calidad asistencial y prevención de enfermedad tromboembólica venosa. Nuevo modelo de gestión / Quality of care and prevention of venous thromboembolic disease. A new management model

Uno de los objetivos de cualquier programa de salud debe ser alcanzar un alto grado de calidad asistencial, y para ello se debe tener en cuenta conceptos como nivel científico-técnico, eficacia, efectividad, eficiencia, adecuación, continuidad, accesibilidad, satisfacción del usuario y otros como solidaridad, equidad y ética. Para cualquier plan de mejora de la calidad que se quiera implementar es importante la activa participación de los profesionales. Por tal motivo se ha formado un nuevo modelo de gestión que se basa en pequeñas unidades o grupos compuestos por los profesionales, y cuyas funciones son la planificación, la ejecución, el control y la evaluación de las diversas actividades que se desprenden de un determinado proceso asistencial, tales como las relacionadas con la docencia, la investigación, la gestión y la asistencia (grupos DIGA). En el presente estudio, uno de los grupos formados se encarga de las acciones de mejora del proceso asistencial prevención de la enfermedad tromboembólica venosa (PETEV), para el que hay una gran variedad de criterios terapéuticos, por lo que resulta fundamental conocer qué es lo que se hace, cómo se hace y cuáles son los resultados alcanzados. Por tal motivo, el grupo de profesionales confecciona una guía con recomendaciones para la PETEV, participa en su difusión, y se encarga de implementar la medición de los resultados y su posterior evaluación y aplicación. Dichos resultados muestran el grado de calidad alcanzado en el proceso asistencial en cuestión, y permiten detectar rápidamente situaciones de baja calidad, para tratar de revertirlas lo más rápidamente posible y, de esa forma, garantizar la calidad

One of the goals of any health program should be to achieve high quality of care. To do this, certain concepts need to be kept in mind such as scientific-technical standards, efficacy, effectiveness, efficiency, appropriateness, continuity, accessibility, and patient satisfaction, as well as others such as solidarity, equity and ethics. For any quality improvement plan, active professional participation is important. For this reason, a new management model was created, based on small units or groups composed of professionals, whose functions were the planning, execution, control and evaluation of the different activities related to a specific process, such as those related to teaching, research, management and medical care (ERMA groups). In the present study, one of the groups formed was given the task of improving the prevention of venous thromboembolic disease, which has multiple therapeutic criteria. Therefore, it is essential to specify what is done, how it is done and what results are obtained. For this reason, the group of professionals drew up a guideline with recommendations for the prevention of venous thromboembolic disease. The group participated in the plan's diffusion, and measured the results and their subsequent evaluation and application. These results show the quality grade obtained in a specific process, allow areas of low quality to be rapidly detected and corrected, thus guaranteeing quality
