A case of recurrent erythema induratum of Bazin in a patient with myelodysplastic syndrome.

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.

One Case of Drug-Resistant Invasive Fungal Infection after Myelodysplastic Syndrome Chemotherapy.

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.

Treatment of Anemia in Lower-Risk Myelodysplastic Syndrome.

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.

Systemic inflammatory autoimmune disease before allogeneic hematopoietic stem cell transplantation is a risk factor for death in patients with myelodysplastic syndrome or chronic myelomonocytic leukemia.

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.

Successful treatment of concurrent cold agglutinin disease and myelodysplastic syndrome.

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.

Optimal Treatment Approaches to Intestinal Behçet's Disease Complicated by Myelodysplastic Syndrome: The KASID and KSBD Multicenter Study.

PURPOSE: Studies on intestinal Behçet's disease (BD) complicated by myelodysplastic syndrome (MDS) are rare, and no established therapeutic guidelines exist. This study aimed to evaluate the clinical presentation and outcomes of patients with intestinal BD complicated by MDS (intestinal BD-MDS) and suggest a treatment strategy. MATERIALS AND METHODS: Data from patients with intestinal BD-MDS from four referral centers in Korea who were diagnosed between December 2000 and December 2022 were retrospectively analyzed. Clinical features and prognosis of intestinal BD-MDS compared with age-, sex-matched intestinal BD without MDS were investigated. RESULTS: Thirty-five patients with intestinal BD-MDS were included, and 24 (70.6%) had trisomy 8. Among the 35 patients, 23 (65.7%) were female, and the median age at diagnosis for intestinal BD was 46.0 years (range, 37.0-56.0 years). Medical treatments only benefited eight of the 32 patients, and half of the patients underwent surgery due to complications. Compared to 70 matched patients with intestinal BD alone, patients with intestinal BD-MDS underwent surgery more frequently (51.4% vs. 24.3%; p=0.010), showed a poorer response to medical and/or surgical treatment (75.0% vs. 11.4%; p<0.001), and had a higher mortality (28.6% vs. 0%; p<0.001). Seven out of 35 patients with intestinal BD-MDS underwent hematopoietic stem cell transplantation (HSCT), and four out of the seven patients had a poor response to medical treatment prior to HSCT, resulting in complete remission of both diseases. CONCLUSION: Patients with intestinal BD-MDS frequently have refractory diseases with high mortalities. HSCT can be an effective treatment modality for medically refractory patients with intestinal BD-MDS.

Rapid progression from MDS to AML with gastric submucosal tumour as an extramedullary infiltration.

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.

Could it be VEXAS?

We report the case of the youngest patient described with VEXAS syndrome associated with MDS-IB1, successfully treated with azacitidine-venetoclax and allogeneic stem cell transplant.

[Survival and Prognosis of Patients with Acute Myeloid Leukemia with Myelodysplasia-Related Changes Transformed from Myelodysplastic Syndrome].

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.

Ocular and orbital manifestations in VEXAS syndrome.

BACKGROUND: VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) is a hematoinflammatory disease that typically affects adults. It results from a somatic mutation of the E1 ubiquitin conjugating enzyme encoded by the UBA1 gene. VEXAS is frequently accompanied by myelodysplastic syndrome (MDS). The purpose of this study is to describe the ocular and orbital manifestations of VEXAS patients in a case series in our medical centre. METHODS: A retrospective chart review was performed for all patients who were diagnosed with VEXAS syndrome in a tertiary medical centre over two years. RESULTS: Eight patients were identified with VEXAS. In six patients, the diagnosis was confirmed by genomic sequencing. Two patients were identified based on their phenotype. All patients were males. The mean age at diagnosis was 78.7 years. In two patients, the ocular manifestation was the presenting symptom for VEXAS. Seven patients (87.5%) had history of MDS. Systemic inflammation manifestations include: skin rash (n = 5), recurrent fevers (n = 2), relapsing polychondritis (n = 2), pleuritis and pleural effusion (n = 2), poly arteritis nodosa- PAN (n = 1) and thrombophlebitis (n = 1). Seven (87%) patients were presented with periorbital oedema. Three patients showed orbital inflammation. Dacryoadenitis was observed in two patients, and extraocular muscle (EOM) myositis was detected in two patients. Four patients demonstrated ocular inflammation such as: episcleritis, scleritis and anterior uveitis. CONCLUSION: ocular manifestations in VEXAS include orbital inflammation, dacryoadenitis, myositis, uveitis, scleritis, episcleritis and periorbital oedema. We recommend that in old male patients, with history of haematological disorder, presenting with ocular symptom, VEXAS investigation should be taken into consideration.

Case report: diagnosis of VEXAS syndrome in a patient with therapy-resistant large vessel vasculitis.

VEXAS (Vacuoles, E1 enzyme, X-linked, Auto-Inflammatory, Somatic) syndrome is a recently identified multisystemic auto-inflammatory condition caused by somatic mutations in the UBA1 gene. This syndrome presents diagnostic challenges due to its rare nature and varied clinical manifestations. We report the clinical course of a 76-year-old man with therapy-resistant large vessel vasculitis and myelodysplastic syndrome (MDS), eventually confirmed as VEXAS syndrome. The patient responded well to corticosteroid therapy. However, over two years, he faced multiple hospital admissions due to inflammatory flare-ups during corticosteroid tapering. Several immunosuppressive therapies were attempted without success. Further research is essential to understand this complex syndrome's pathophysiology, genetics, clinical course, and treatment options, ultimately benefiting both patients and healthcare providers.

Ischemic stroke as the initial presentation in acute myeloid leukemia vs. myelodysplastic syndrome: a case report and literature review with pathophysiological and clinical exploration.

BACKGROUND: Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) present intricate challenges due to their diverse clinical manifestations and thrombotic complications. Thromboembolism (TE) incidence in newly diagnosed AML patients is noteworthy, with arterial TE linked to poorer overall survival. Ischemic strokes, although relatively low in prevalence, carry significant clinical implications. CASE DESCRIPTION: We report the case of an 84-year-old male with Type 2 Diabetes, Hypertension, and Chronic Kidney Disease, presenting with seizures, focal neurological deficits, and pancytopenia. An unexpected diagnosis of AML or MDS emerged during the investigation. Despite interventions, the patient's condition deteriorated, leading to a fatal outcome weeks later. CONCLUSION: This case underscores the intricate relationship between hematologic malignancies and ischemic stroke. The rarity of this complication emphasizes the importance of understanding the multifaceted mechanisms at play, including hyperleukocytosis, pro-inflammatory cytokine release, coagulation cascade activation, and direct interactions with endothelial cells. In our literature review, analysis of 15 cases, including ours, revealed a wide age range (3-87 years) and a gender bias towards females. AML diagnosis was predominant, with uniformly low platelet counts. Cortical infarctions, especially in the anterior circulation, were common. Hyperleukocytosis, disseminated intravascular coagulation (DIC), and fatal outcomes were observed in a subset of cases. Despite the grim statistics and often poor prognosis, the identification of specific risk factors, such as thrombocytopenia and cytogenetic abnormalities, offers avenues for targeted prevention and management.

Cardiac effects of deferasirox in transfusion-dependent patients with myelodysplastic syndromes: TELESTO study.

Iron overload from repeated transfusions has a negative impact on cardiac function, and iron chelation therapy may help prevent cardiac dysfunction in transfusion-dependent patients with myelodysplastic syndromes (MDS). TELESTO (NCT00940602) was a prospective, placebo-controlled, randomised study to evaluate the iron chelator deferasirox in patients with low- or intermediate-1-risk MDS and iron overload. Echocardiographic parameters were collected at screening and during treatment. Patients receiving deferasirox experienced a significant decrease in the composite risk of hospitalisation for congestive heart failure (CHF) or worsening of cardiac function (HR = 0.23; 95% CI: 0.05, 0.99; nominal p = 0.0322) versus placebo. No significant differences between the arms were found in left ventricular ejection fraction, ventricular diameter and mass or pulmonary artery pressure. The absolute number of events was low, but the enrolled patients were younger than average for patients with MDS, with no serious cardiac comorbidities and a modest cardiovascular risk profile. These results support the effectiveness of deferasirox in preventing cardiac damage caused by iron overload in this patient population. Identification of patients developing CHF is challenging due to the lack of distinctive echocardiographic features. The treatment of iron overload may be important to prevent cardiac dysfunction in these patients, even those with moderate CHF risk.
