Abstract
Coagulation disorders frequently complicate the clinical course of acute myeloid leukemia (AML) patients. This study examined the frequency and prognostic significance, with regards of early mortality, of the presence of overt disseminated intravascular coagulation (DIC) at AML diagnosis and its correlation with clinical and biological characteristics. A retrospective analysis of 351 newly diagnosed non-promyelocytic AML patients was conducted, utilizing the 2018 ISTH DIC-Score criteria to evaluate the presence of overt DIC at AML onset. The study cohort had a median age of 65 years with a predominance of male gender (59 %). Overt DIC was present in 21 % of cases and was associated with advanced age, comorbidities, poor performance status, hyperleukocytosis, LDH levels, NPM1 mutations, expression of CD33 and CD4, and lack of expression of CD34. With a median follow-up of 72 months (3-147 months), the 6-year overall survival (OS) was 17.4 %, with patients having overt DIC showing significantly poorer outcomes (7.2 % compared to 20.3 % of those without DIC, p < 0.001). Patients with overt DIC showed markedly high early mortality rates at 30 (42.5 % vs 8 %), 60 (49.3 % vs 16.9 %), and 120 days (64.4 % vs 25.6 %) from disease onset. In multivariate analysis overt DIC retained its independent prognostic value for early mortality. In conclusion, the prevalence and clinical relevance of DIC in non-promyelocytic AML is not negligible, underlining its potential as an unfavorable prognostic marker. In newly diagnosed patients with AML, early recognition and measure to counteract coagulation disturbances might help mitigate the elevated mortality risk associated with DIC.

Simplified predictive scores for thrombosis and bleeding complications in newly diagnosed acute leukemia patients. Thromb J 2023; 21:65. [PMID: 37291589 DOI: 10.1186/s12959-023-00506-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 05/24/2023] [Indexed: 06/10/2023] Open
Abstract
BACKGROUND Bleeding and thrombotic complications are the leading causes of death in acute leukemia patients. The Conventional International Society of Thrombosis and Haemostasis Disseminated Intravascular Coagulation (ISTH DIC) scoring system is utilized to assess DIC diagnoses in various conditions. Nevertheless, limited studies have tested the system's accuracy in predicting thrombo-hemorrhagic events in individuals with acute leukemia. This study aimed to (1) validate the ISTH DIC scoring system and (2) propose a new Siriraj Acute Myeloid/Lymphoblastic Leukemia (SiAML) bleeding and thrombosis scoring system for thrombohemorrhagic risk assessment in acute leukemia. METHODS We conducted a retro-prospective observational study of newly diagnosed acute leukemia patients between March 2014 and December 2019. We recorded thrombohemorrhagic episodes within 30 days postdiagnosis and DIC profiles, including prothrombin time, platelet level, D-dimer, and fibrinogen. The sensitivities, specificities, positive and negative predictive values, and areas under receiver operating characteristic curves for the ISTH DIC and SiAML scoring systems were calculated. RESULTS In all, 261 acute leukemia patients were identified: 64% with acute myeloid leukemia, 27% with acute lymphoblastic leukemia, and 9% with acute promyelocytic leukemia. Overall bleeding and thrombotic events were 16.8% and 6.1%, respectively. With a cutoff of 5 for the ISTH DIC score, the sensitivity and specificity for bleeding prediction were 43.5% and 74.4%, respectively, while the corresponding values for thrombotic prediction were 37.5% and 71.8%, respectively. D-dimer > 5000 µg FEU/L and fibrinogen ≤ 150 mg/dL were significantly associated with bleeding. A SiAML-bleeding score was calculated using these factors, with a sensitivity and specificity of 65.2% and 65.6%, respectively. Conversely, D-dimer > 7000 µg FEU/L, platelet > 40 × 109/L, and white blood cell level > 15 × 109/L were significant variables related to thrombosis. Using these variables, we established a SiAML-thrombosis score with a sensitivity and specificity of 93.8% and 66.1%, respectively. CONCLUSIONS The proposed SiAML scoring system might be valuable for prognosticating individuals at risk for bleeding and thrombotic complications. Prospective validation studies are needed to verify its usefulness.

Abstract
PurposeTo investigate changes in retinal circulation and the choroid in patients with acute myeloid leukemia (AML) in the acute and remission stages, to analyze the correlation between retinal circulation and laboratory parameters, and to assess risk factors associated with leukemic retinopathy.MethodsForty-eight patients (93 eyes) with AML were enrolled and divided into two groups according to fundus examination findings: the retinopathy and no retinopathy groups. Patients underwent eye measurements before treatment and after remission. Macular vessel density (VD), perfusion density (PD), foveal avascular zone (FAZ), and choroidal thickness (ChT) were measured using optical coherence tomography angiography. Patients with healthy eyes were recruited as control participants.ResultsPatients with leukemic retinopathy had higher measurements of white blood cells (WBCs), circulating blasts, fibrin degradation products, and cross-linked fibrin degradation products (D-dimer) and a lower hemoglobin (HB) count (p < 0.05). In the acute phase of the disease, the VD and PD were lower and the ChT was thicker in patients with AML than in controls (p < 0.05), irrespective of the presence of leukemic retinopathy; however, the patients were partially recovered in the remission stage. The VD was lower in patients with higher WBC (r = −0.217, p = 0.036), D-dimer (r = −0.279, p = 0.001), fasting blood glucose (FBG) (r = −0.298, p = 0.004) and triglyceride (r = −0.336, p = 0.001) levels. The FAZ area was negatively correlated with HB (r = −0.258, p = 0.012).ConclusionPatients with AML appear to have subclinical retinal perfusion loss and choroidal thickening in the acute phase of the disease, but this is reversible. Injury to bone marrow function may cause a decrease in retinal perfusion. Leukemic retinopathy is associated with abnormal hematologic parameters and coagulopathy.

Abstract
OBJECTIVES We aimed to detect the incidence of disseminated intravascular coagulation (DIC) in patients with acute leukemia (AL) and find out its association with types of AL and patients' clinical and pathological parameters. METHODS In this prospective study, 59 newly diagnosed adults with AL were clinically examined and screened for DIC presentation time. Coagulation tests, including prothrombin time, activated partial thromboplastin time, fibrinogen level, D-dimer, antithrombin, and protein C and protein S levels were all assessed. The International Society for Thrombosis and Hemostasis scoring system was adopted to diagnose overt DIC. RESULTS The age of the studied patients ranged from 15 to 81 years with a median of 41 years; male to female ratio was 1.1:1. acute myeloid leukemia (AML) constituted 64.4% of the total cases (38 patients). DIC was detected in 28 patients (47.5%); its incidence was higher in AML than in acute lymphoblastic leukemia (ALL) (52.6% vs. 38.1%). Overt DIC was significantly associated with bleeding manifestations, duration of symptoms, and leukocytosis ( P -values = 0.050, 0.044, and 0.003, respectively). Bleeding events were encountered in 50.8% of patients (25 AML and 5 ALL patients). Bleeding was associated significantly with leukocytosis, thrombocytopenia, and low fibrinogen level. Thrombosis was found in two patients (3.4%) at presentation. CONCLUSIONS Overt DIC was common in patients with AL at presentation, mostly in AML. Routine testing for coagulopathy in newly diagnosed AL patients will possibly aid in improving the overall patients' survival.

Abstract
Introduction The objective of the study was to assess the impact of coagulopathy in risk-stratified acute promyelocytic leukemia (APML) patients irrespective of bleeding manifestation. Patients and methods This was a cross-sectional study design conducted at the National Institute of Blood Diseases and Bone Marrow Transplantation (NIBD & BMT) from November 2019 to December 2021. A total of 62 patients between three years to 74 years of age of either gender and treatment-naive cases of APML were included in the study. Morphological diagnosis was made on bone marrow samples, and confirmation was done by karyotyping/fluorescence in situ hybridization (FISH) and/or polymerase chain reaction (PCR). Complete blood count (CBC), prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, and fibrinogen levels were done for bleeding risk assessment. Cases other than APML and cases on treatment were excluded from the study. Results A total of 85 APML patients were registered at our institute. Among them, 62 (73%) were included in the analysis as per the inclusion criteria of the study. The median age was 32 (3-74) years, with a male predominance of 34 (55%). According to the Sanz score, 18 (29%) patients were noted to have low risk; however, 22 (35.4%) patients were found to have an intermediate-risk disease and 22 (35.4%) patients had high-risk disease. There was positive bleeding history among 44 (71%) patients, followed by fever in 28 (45%) patients. Raised PT, APTT, and D-dimer were found in 46 (74%), 38 (61%), and 52(83.8%) patients, respectively. Low fibrinogen levels were observed among 16 (26%) patients. The association of risk stratification and bleeding history with CBC and coagulation parameters was observed. Platelet count and total leucocyte count were noted to be significantly associated with risk stratification. However, there was no association observed between the rest of the parameters with risk stratification and bleeding. Conclusion The results of our study suggest that regardless of bleeding symptoms, coagulation parameters must be investigated at the time of diagnosis in patients with suspected APML, and in addition to all-trans-retinoic acid (ATRA), transfusion of fresh frozen plasma should be done. It has clinical value, and adding it to the algorithm of treatment would be beneficial to the patients in the developing world, where resources are already meager.

Abstract
OBJECTIVES Acute promyelocytic leukemia (APL) requires emergent treatment while definitive laboratory results are pending. Following the death of a patient whose diagnosis was delayed, we sought to improve our institution's workflow by using the EPIDEM (Exploration, Promotion, Implementation, Documentation, Evaluation, Modification) quality improvement model. METHODS APL is confirmed by identifying translocation t(15;17)(q24;q21) PML-RARA by using either molecular or cytogenetic methods on peripheral blood or bone marrow specimens. We used the EPIDEM model to decrease the turnaround time (TAT) of molecular diagnosis by improving communication and developing reflex testing. We additionally compared 32 APL cases against a control group of 18 suspected APL cases. RESULTS Our review of 687 multiplex polymerase chain reaction orders and 33 PML-RARA orders (January 2012 to April 2021) showed an initial TAT decrease from 4.48 days to 2.71 days (P < .0001), which further decreased to 0.64 days (P < .0001) after implementation of the PML-RARA qualitative assay. Compared with patients suspected of having APL, patients with confirmed APL had higher dimerized plasmin fragment D (P = .0145), lower fibrinogen (P ≤ .0001), and lower WBC (P ≤ .0001). CONCLUSIONS By using the EPIDEM model, with its emphasis on local context, culture, and resources, improved communication and workflow changes enabled us to reduce the time needed to diagnose APL to 0.64 days and identify potential locally derived screening cutoffs.

Abstract
Disseminated intravascular coagulation (DIC) is a systemic activation of the coagulation system, which results in microvascular thrombosis and, simultaneously, potentially life-threatening haemorrhage attributed to consumption of platelets and coagulation factors. Underlying conditions, e.g. infection, cancer, or obstetrical complications are responsible for the initiation and propagation of the DIC process. This review provides insights into the epidemiology of DIC and the current understanding of its pathophysiology. It details the use of diagnostic biomarkers, current diagnostic recommendations from international medical societies, and it provides an overview of emerging diagnostic and prognostic biomarkers. Last, it provides guidance on management. It is concluded that timely and accurate diagnosis of DIC and its underlying condition is essential for the prognosis. Treatment should primarily focus on the underlying cause of DIC and supportive treatment should be individualised according to the underlying aetiology, patient's symptoms and laboratory records.

Abstract
OBJECTIVES To investigate clinicopathological and molecular features of NPM1-mutated acute myeloid leukemia that presented with infrequent acute promyelocytic leukemia (APL)-like phenotype and clinical presentation. METHODS Cases with both de novo or secondary Acute Myeloid Leukemia (AML) were retrieved. Data from flow cytometry immunophenotyping, cytogenetics, molecular studies, and clinical presentation were analyzed. RESULTS Cases presented with abnormal coagulation parameters and low platelets count; four of them showed a DIC index compatible with overt DIC. Two cases showed Auer rods. In all cases, immunophenotypes mimicked APL: blasts expressed CD33, CD13, and cytoplasmic MPO but did not express CD34, HLA-DR, or CD11b. Notably, CD4 expression was observed in all cases. Neither t(15;17) nor PML/RARα gene rearrangement was detected. NPM1 gene mutation was identified in all cases. In four cases, TET2 or IDH2 co-mutations were identified. CONCLUSIONS Our findings provide additional evidence of association between NPM1-mutated AML with TET2 or IDH2 co-mutations and the APL-like immunophenotype. This AML subset was found to exist in both de novo and secondary AML. High WBC count and blasts with low to moderate side scatter and significant expression of CD4 are observed features that could assist in the differential diagnosis with APL. The occurrence of significant elevated D-dimer levels, or even overt DIC observed at diagnosis in these cases could be relevant for this AML subtype.

Study design and setting: A retrospective chart review study was conducted at An-Najah National University Hospital (NNUH) during the period of January, 2014 to December, 2016. Methodology: The medical records of AML patients treated at NNUH were reviewed. All patients at least 16 years of age diagnosed with de novo AML and started on induction chemotherapy were included. Descriptive statistics were employed to analyze the data. Results: Out of 88 patients diagnosed with AML during the study period, 64 had de novo AML and were included. Median age at diagnosis was 36 years, with a male to female ratio of 1.13:1. Two thirds of the cases were from the West Bank and the remainder were from Gaza. Major complaints at presentation were fatigue (64.1%), fever (46.9%), respiratory tract infections (39.1%) and bruising (28.1%). Hepatomegaly was present in 23.4% and splenomegaly in 34.4%. At presentation, the median white blood cells (WBC) count, hemoglobin (Hb) concentration and platelet count were 30. 5x109/L, 9.3g/dL, and 39.5 x109/L, respectively. According to the French American British (FAB) classification, M4 was the most common subtype (32.8%) followed by M3 (21.9%). After a single cycle of induction chemotherapy complete remission (CR) was seen in 26 (41.9%) and non-remission (NR) in 17 (27.4%), while 19 patients (30.6%) died during the first admission for induction. Conclusion: The characteristics of de novo AML in Palestinian patients are comparable to published data elsewhere. M4 was the most common subtype. The outcome of the first cycle of induction chemotherapy was slightly inferior to the published data for M3 patients. Further studies are warranted to identify possible causes.
