RESUMEN

PURPOSE: To explore the potential of testosterone therapy in managing cytopenias in myelodysplastic neoplasm and investigate the link between hypogonadism and hematologic malignancies. METHODS: A case of a patient with intermediate-risk myelodysplastic neoplasm and hypogonadism treated with testosterone replacement therapy is presented. Testosterone, prostate specific antigen, and erythropoietin levels were checked prior to therapy initiation and 3 months after. Blood counts were monitored over time. This is followed by a literature review of testosterone use in myelodysplastic neoplasm and the prevalence of hypogonadism in hematologic malignancies. RESULTS: The patient showed sustained improvement in anemia with testosterone therapy and reported subjective improvement in his weakness and fatigue. This improvement occurred even in the setting of an undetectable follow up erythropoietin level. His repeat prostate specific antigen levels remained low, while testosterone levels showed marked improvement. The literature review demonstrated positive response rates for testosterone in treating myelodysplastic neoplasm-related cytopenias, and showed a higher incidence of hypogonadism in hematologic malignancies. CONCLUSION: Our review suggests that the use of testosterone in low and intermediate-risk myelodysplastic neoplasm is underexplored and poses to have significant potential as a future therapeutic agent, after careful consideration of risks and benefits. In addition, the incidence of hypogonadism in myelodysplastic neoplasm and its potential impact on exacerbating cytopenias in myelodysplastic neoplasm warrants further investigation.

RESUMEN

INTRODUCTION: Periarteritis nodosa (PAN) is a vasculitis affecting medium-vessel and may be associated with myelodysplastic syndrome. This association needs a simultaneous treatment of the vascular and the hematological disease. However limited data are available on the benefit of hematological treatment, and in particular allogeneic stem cell transplantation, in this situation. CASE REPORT: A 32-year-old patient with refractory periarteritis nodosa and simultaneous myelodysplastic syndrome, was treated with chemotherapy followed by hematopoietic stem cell allograft. The symptoms relating to PAN improved, allowing to decrease the dose of prednisone down to 5mg/d. However, a hematological relapse occurred two months later leading to the patient's death. CONCLUSION: Hematopoietic stem cell allograft may represent a therapeutic option in the management of severe or refractory autoimmune diseases when the hematological indication is retained.

RESUMEN

Myelodysplastic syndrome (MDS) represents a spectrum of myeloid disorders occasionally linked to autoimmune diseases. Here, we present a case of a 60-year-old man demonstrating an unusual coexistence of MDS with warm-autoantibody autoimmune hemolytic anemia (wAIHA). Diagnostic evaluation, including positive direct antiglobulin testing, confirmed the autoimmune etiology of his anemia despite his low-risk MDS classification. Prompt initiation of prednisone therapy resulted in significant hematological and clinical improvement, allowing for a conservative management approach without transfusion requirements. This case underscores the importance of identifying the relationship between wAIHA and MDS, particularly in low-risk scenarios. Moreover, these findings suggest the efficacy of corticosteroids in managing autoimmune anemia in the context of concomitant wAIHA and MDS.

RESUMEN

BACKGROUND: The preplanned interim analysis of the COMMANDS trial showed greater efficacy of luspatercept than epoetin alfa for treating anaemia in erythropoiesis-stimulating agent (ESA)-naive patients with transfusion-dependent, lower-risk myelodysplastic syndromes. In this Article, we report the results of the primary analysis of the trial. METHODS: COMMANDS is a phase 3, open-label, randomised, controlled trial conducted at 142 sites in 26 countries. Eligible patients were those aged 18 years or older, with myelodysplastic syndromes of very low risk, low risk, or intermediate risk (as defined by the Revised International Prognostic Scoring System), who were ESA-naive and transfusion dependent, and had a serum erythropoietin concentration of less than 500 U/L. Patients were stratified by baseline red blood cell transfusion burden, serum erythropoietin concentration, and ring sideroblast status, and randomly allocated (1:1) to receive luspatercept (1·0-1·75 mg/kg body weight, subcutaneously, once every 3 weeks) or epoetin alfa (450-1050 IU/kg body weight, subcutaneously, once a week; maximum total dose 80 000 IU) for at least 24 weeks. The primary endpoint was red blood cell transfusion independence lasting at least 12 weeks with a concurrent mean haemoglobin increase of at least 1·5 g/dL (weeks 1-24), evaluated in the intention-to-treat population. The safety population included all patients who received at least one dose of treatment. This trial is registered with ClinicalTrials.gov (NCT03682536; active, not recruiting). FINDINGS: Between Jan 2, 2019, and Sept 29, 2022, 363 patients were screened and randomly allocated: 182 (50%) to luspatercept and 181 (50%) to epoetin alfa. Median age was 74 years (IQR 69-80), 162 (45%) patients were female, and 201 (55%) were male. 289 (80%) were White, 44 (12%) were Asian, and two (1%) were Black or African American. 23 (6%) were Hispanic or Latino and 311 (86%) were not Hispanic or Latino. Median follow-up for the primary endpoint was 17·2 months (10·4-27·7) for the luspatercept group and 16·9 months (10·1-26·6) for the epoetin alfa group. A significantly greater proportion of patients in the luspatercept group reached the primary endpoint (110 [60%] vs 63 [35%]; common risk difference on response rate 25·4% [95% CI 15·8-35·0]; p<0·0001). Median follow-up for safety analyses was 21·4 months (IQR 14·2-32·4) for the luspatercept group and 20·3 months (12·7-30·9) for the epoetin alfa group. Common grade 3-4 treatment-emergent adverse events occurring among luspatercept recipients (n=182) were hypertension (19 [10%] patients), anaemia (18 [10%]), pneumonia (ten [5%]), syncope (ten [5%]), neutropenia (nine [5%]), thrombocytopenia (eight [4%]), dyspnoea (eight [4%]), and myelodysplastic syndromes (six [3%]); and among epoetin alfa recipients (n=179) were anaemia (14 [8%]), pneumonia (14 [8%]), neutropenia (11 [6%]), myelodysplastic syndromes (ten [6%]), hypertension (eight [4%]), iron overload (seven [4%]), and COVID-19 pneumonia (six [3%]). The most common serious treatment-emergent adverse events in both groups were pneumonia (nine [5%] luspatercept recipients and 13 [7%] epoetin alfa recipients) and COVID-19 (eight [4%] luspatercept recipients and ten [6%] epoetin alfa recipients). One death (due to acute myeloid leukaemia) considered to be luspatercept-related was reported at the interim analysis. INTERPRETATION: Luspatercept represents a new standard of care for ESA-naive patients with transfusion-dependent, lower-risk myelodysplastic syndromes. Significantly more patients had red blood cell transfusion independence and haematological improvement with luspatercept than with epoetin alfa, with benefits observed across patient subgroups.

RESUMEN

We describe a case of erythema induratum of Bazin (EIB) that presented recurrently on the extremities during treatment with anti-tuberculosis medications. The anti-tuberculosis medications were effective, so they were continued despite the occurrence of the EIB lesions, and those lesions disappeared 5 months after first appearing. EIB is currently considered a multifactorial disorder with many different causes, with tuberculosis being an example, and it is thought to be a hypersensitive immune response to Mycobacterium tuberculosis. The clinical manifestations may fluctuate depending on the immune response of the host. Our patient was affected with myelodysplastic syndrome, and we believe that this was a major factor that interfered with a normal immune response. This case illustrates the importance of providing intensive anti-tuberculosis treatment from the start, and in cases where EIB co-presents, to continue this treatment until the end, in order to prevent relapse.

RESUMEN

The development of myeloid malignancies is a multi-step process starting from pre-malignant stages. Large-scale studies on clonal hematopoiesis of indeterminate potential (CHIP) identified this condition as a risk factor for developing hematologic malignancies, in particular myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). In parallel, CHIP was found to confer an enhanced thrombotic risk, in particular for cardiovascular diseases. In a similar fashion, in recent years, alongside their life-threatening features, increasing attention has been drawn toward thrombotic complications in myeloid malignancies. Thus, the purpose of this review is to gather a growing body of evidence on incidence, pathogenesis and clinical impact of thrombosis in myeloid malignancies at every step of malignant progression, from CHIP to AML.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the therapeutic regimen of a patient with myelodysplastic syndrome (MDS) who developed invasive fungal infections caused by drug-resistant Candida tropicalis after chemotherapy and to investigate the effect of drug treatment. METHODS: We referred to the Diagnostic Criteria and Treatment Principles of invasive fungal diseases in patients with hematological diseases and malignant tumors (2013, fourth revised edition) and the Expert Consensus on Clinical Application of Posaconazole (2022 Edition). In addition, the drug treatment regimens of drug-resistant Candida tropicalis were reviewed. The doctors in charge were involved in the drug treatment process, and the ra-tional drug use was selected according to evidence-based medicine. RESULTS: After 4 months of use, the nodules around the body disappeared, and there was no further fever during follow-up. After 6 months of use, posaconazole was discontinued, and the patient continued to follow-up for 1 month without further fever or nodules. CONCLUSIONS: The combination of posaconazole, amphotericin B liposome, and micafungin is effective in the treatment of fluconazole-resistant Candida tropicalis infection.

RESUMEN

OPINION STATEMENT: A majority of patients with lower-risk myelodysplastic syndrome (MDS) will present with or develop anemia. Anemia in MDS is associated with decreased quality of life and may correlate with decreased progression-free survival and overall survival. In this state of the art review we summarize current risk stratification approaches to identify lower-risk MDS (LR-MDS), the natural history of the disease, and meaningful clinical endpoints. The treatment landscape of LR-MDS with anemia is also rapidly evolving; we review the role of supportive care, erythropoietin stimulating agents, lenalidomide, luspatercept, hypomethylating agents (HMAs), and immunosuppressive therapy (IST) in the management of LR-MDS with anemia. In patients with deletion 5q (del5q) syndrome lenalidomide has both efficacy and durability of response. For patients without del5q who need treatment, the management approach is impacted by serum erythropoietin (EPO) level, SF3B1 mutation status, and ring sideroblast status. Given the data from the Phase III COMMANDS trial, we utilize luspatercept in those with SF3B1 mutation or ring sideroblasts that have an EPO level < 500 U/L; in patients without an SF3B1 mutation or ring sideroblasts there is equipoise between luspatercept and use of an erythropoietin stimulating agent (ESA). For patients who have an EPO level ≥ 500 U/L or have been previously treated there is not a clear standard of care. For those without previous luspatercept exposure it can be considered particularly if there is an SF3B1 mutation or the presence of ring sideroblasts. Other options include HMAs or IST; the Phase III IMERGE trial supports the efficacy of the telomerase inhibitor imetelstat in this setting and this may become a standard option in the future as well.

RESUMEN

Herein, we describe a case of severe anemia presenting with myelodysplastic syndrome with cold agglutinin disease that was successfully treated by a moderate dose of steroids followed by cyclosporine. In patients with myelodysplastic syndrome, autoimmunity in erythroid cells is occasionally demonstrated, and autoimmune hemolytic anemia is seen in some patients. However, hemolytic anemia with cold agglutinin in patients with myelodysplastic syndrome is less common, and the effect of corticosteroids for autoimmune hemolytic anemia caused by cold agglutinin is thought to be limited. Although the elevated levels of reticulocytes and LDH are usually caused by ineffective hematopoiesis in myelodysplastic syndrome, clinicians should be aware of latent cold agglutinin disease. In the present case, in addition to the improvement of erythroid dysplasia, the corticosteroid-sparing effect on cold agglutinin disease may have played a role in the mechanism underlying the effectiveness of cyclosporine.

RESUMEN

Myelodysplastic syndrome (MDS) is well known to be complicated by systemic inflammatory autoimmune disease (SIADs). However, it remains unclear how the prognosis after allogenic hematopoietic stem cell transplantation (allo-HSCT) in patients with MDS is impacted by SIADs that occur before allo-HSCT. Therefore, we hypothesized that SIADs before allo-HSCT may be a risk factor for negative outcomes after allo-HSCT in patients with MDS. We conducted a single-center, retrospective, observational study of sixty-nine patients with MDS or chronic myelomonocytic leukemia who underwent their first allo-HCT. Fourteen of the patients had SIADs before allo-HSCT. In multivariate analysis, the presence of SIADs before allo-HSCT was an independent risk factor for overall survival (HR, 3.36, 95% confidence interval: 1.34-8.42, p = 0.009). Endothelial dysfunction syndrome was identified in five of 14 patients with SIADs who required immunosuppressive therapy or intensive chemotherapy, and notably, all patients with uncontrollable SIADs at allo-HSCT developed serious endothelial dysfunction syndrome and died in the early phase after allo-HSCT. The development of SIADs in the context of MDS is thought to reflect the degree of dysfunction of hematopoietic cells in MDS and suggests a higher risk of disease progression. In addition, MDS patients with SIADs before allo-HSCT are considered to be at higher risk of endothelial dysfunction syndrome because of preexisting vascular endothelial dysfunction due to SIADs. In conclusion, SIADs before allo-HSCT constitute an independent risk factor for death in MDS patients undergoing allo-HSCT.

RESUMEN

OBJECTIVE: To explore the risk factors affecting the survival and efficacy of patients with acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) transformed from myelodysplastic syndrome (MDS). METHODS: The clinical data of 60 patients with AML-MRC transformed from MDS who hospitalized in The Third Affiliated Hospital of Soochow University from January 2010 to December 2021 were retrospectively analyzed. The demographic data and laboratory parameters, cytogenetic karyotypes, target genes of AML detected by next generation sequence, risk stratification, treatment regimen, therapeutic efficacy and survival outcome were documented. Rank sum test and Chi-square test or Fisher exact test were used to compare the survival and efficacy. The effects of clinical parameters, risk stratification and treatment regimens on the survival and efficacy of the AML-MRC patients were analyzed by univariate and multivariate analysis. RESULTS: The median overall survival (OS) of the AML-MRC patients was 4.5 months, the 1-year OS rate was 28.3%, and the complete remission (CR) rate after treatment was 33.3%. The univariate analysis showed that age≥60 years, leukocytosis, severe thrombocytopenia, poor-risk group and only accepted hypomethylating agents(HMAs) or supportive therapy were the risk factors affecting OS. COX multivariate analysis showed that thrombocytopenia ( HR=4.46), HMAs therapy (compared to transplantation, HR=10.47), supportive therapy (compared to transplantation, HR=25.80) and poor-risk group (compared to medium-risk group, HR=13.86) were independent hazard factors for median OS of patients with AML-MRC. The univariate analysis showed that the risk factors affecting 1-year OS in patients with AML-MRC were age≥60 years, thrombocytopenia, time of transformation from MDS to AML (TTA)≥3 months, fibrinogen-albumin ratio index (FARI)≥0.07, CONUT score≥5, poor-risk group and supportive therapy. Binary logistic regression analysis showed that the independent risk factors for 1-year OS in AML-MRC patients were age≥60 years ( HR=11.23), thrombocytopenia ( HR=8.71), FARI≥0.07 ( HR=5.19) and poor-risk group ( HR=14.00). The risk factors affecting CR of AML-MRC patients in univariate analysis were age≥60 years, thrombocytopenia, FARI≥0.1, CONUT score≥5, poor-risk group and supportive therapy, while binary logistic regression analysis showed that age≥60 years( HR=7.35), CONUT score≥5 ( HR=9.60), thrombocytopenia ( HR=12.05) and poor-risk group ( HR=32.5) were independent risk factors affecting CR of the patients. CONCLUSION: The OS of AML-MRC patients is poor, old age(≥60 years old), supportive therapy, HMA therapy, poor-risk, thrombocytopenia, FARI≥0.07 and CONUT score≥5 may be associated with poor prognosis.

RESUMEN

We present a rare case of myeloid sarcoma in the stomach of an elderly woman initially diagnosed with anaemia. Myeloid sarcoma, an unusual extramedullary manifestation of acute myeloid leukaemia (AML), primarily affects lymph nodes, bones, spine and skin, with gastrointestinal involvement being infrequent. Despite normal results from the initial endoscopy, a follow-up examination after 4 months revealed multiple submucosal gastric tumours. These developments coincided with worsening of anaemia and an increase in peripheral myeloblasts. Pathological evaluation and immunohistochemical staining confirmed gastric extramedullary infiltration associated with AML. This case highlights the importance of comprehensive diagnostic processes when suspecting leukaemic transformations, especially in myelodysplastic syndrome (MDS). Due to financial constraints, additional critical studies such as cytogenetics and next-generation sequencing were not performed. Nonetheless, this rare case demonstrates the visual observation of rapid progression from MDS to AML and concurrent early myeloid sarcoma development in an elderly patient.
