Adult-onset Still's disease (AOSD) is a rare systemic auto-inflammatory disorder (SAID). Although the pathogenesis of the disease is complex and far from being fully understood, recent progresses in pathophysiological knowledge have paved the way to new diagnostic approaches. Indeed, AOSD diagnosis can be a real challenge, owing to its infrequency, and to the lack of specificity of the principal clinical features (high fever, arthralgia or arthritis, skin rash) and laboratory findings (elevated acute phase reactants, hyperleukocytosis ≥ 10,000 cells/mm(3) with neutrophils ≥80%)...

We present the management of a 15-year-old girl with acute myeloid leukemia who presented with massive hyperleukocytosis and neurological deficit due to intracerebral hemorrhage. Surgical intervention was considered but ultimately not undertaken because of the presence of massive hyperleukocytosis, thrombocytopenia, hypokalemia, and considerable discrepancy between the oxygen saturation values determined mechanically and by peripheral oximetry. Aggressive treatment of the hyperleukocytosis was immediately started, which improved the patient's overall condition and rendered surgical intervention unnecessary...

BACKGROUND: The prognostic impact of central nervous system (CNS) involvement in children with acute myeloid leukemia (AML) has varied in past trials, and controversy exists over the degree of involvement requiring intensified CNS therapy. Two recent Children's Oncology Group protocols, AAML03P1 and AAML0531, directed additional intrathecal (IT) therapy to patients with CNS2 (≤5 white blood cell [WBC] with blasts) or CNS3 (>5 WBC with blasts or CNS symptoms) disease at diagnosis...

Up to 20% of acute myeloid leukemia (AML) patients present initially with hyperleukocytosis, placing them at increased risk for early mortality during induction. Yet, it is unknown whether hyperleukocytosis still retains prognostic value for AML patients undergoing hematopoietic stem cell transplantation (HSCT). Furthermore, it is unknown whether hyperleukocytosis holds prognostic significance when modern molecular markers such as FLT3-ITD and NPM1 are accounted for. To determine whether hyperleukocytosis is an independent prognostic factor influencing outcome in transplanted AML patients we performed a retrospective analysis using the registry of the acute leukemia working party of the European Society of Blood and Marrow Transplantation...

Patients presenting with hyperleukocytosis secondary to acute leukemia, with total leukocyte count or blast count more than 100,000/μL are often considered for leukapheresis, especially if clinical signs of leukostasis are present. Leukostasis is often associated with high morbidity and mortality in patients with leukemic processes. The main goal of management of hyperleukocytosis and/or leukostasis is to reduce the blast count before initiation of chemotherapy. Leukapheresis is often used prophylactically to prevent leukostasis or to provide symptomatic relief...

In acute myeloid leukemia (AML), mutations of the Fms-like tyrosine kinase 3 receptor (FLT3) and its overexpression are related with hyperleukocytosis, higher risk of relapse, and decrease of both disease-free survival and overall survival. It has been suggested that this phenomenon confers proliferative and survival advantages to the malignant blast cells. As a consequence, it is an attractive therapeutic target. As the best treatment strategy for mutated FLT3 AML remains to be defined, the addition of FLT3 inhibitor drugs to chemotherapy or to the bone marrow transplant approach has become a growing strategy...

Hyperleukocytosis in patients with acute myeloid leukemia (AML) can lead to leukostasis, which if left untreated, has a high mortality. While prompt cytoreductive chemotherapy is essential, treatment with leukapheresis is controversial. This study investigated the outcomes of patients with hyperleukocytosis who received leukapheresis. From 5596 encounters of patients with leukemia seen at Houston Methodist Hospital, we identified 26 patients who had newly diagnosed AML, WBC >50,000/μL, and received leukapheresis...

History, examinations and diagnosis A young patient consulted the hospital because of spontaneous hematomas. The combination of pancytopenia and coagulopathy in the blood and the proving cytogenetic and moleculargenetic examinations of the bone marrow lead to the diagnosis of low-risk acute promyelocytic leukemia (APL). Therapy and clinical course During the combination therapy with ATRA and ATO, the patient developed a severe differentiation syndrome and hyperleukocytosis. Management of the condition was only possible due to clinical expertise and massive substitution of blood products and clotting factors...

Recently, studies in adults with acute promyelocytic leukemia (APL) showed high cure rates in low-risk patients treated with all-trans retinoid acid (ATRA) and arsenic trioxide (ATO), while toxicities were significantly reduced compared to the standard treatment with ATRA and chemotherapy. Here we report about first experience with 11 pediatric patients with low-risk APL treated with ATRA and ATO. All patients stayed in molecular remission. All suffered from hyperleukocytosis. Two patients experienced reversible severe side effects...

Hyperleukocytosis is defined as a white blood cell count greater than 100,000/mL in patients affected by acute leukemia and often it is associated with increased morbidity and mortality, that can be up to 40% if unrecognized. Areas covered: Risk factors include younger age, myelomonocytic or monocytic/monoblastic morphology, microgranular variant of acute promyelocitic leukemia and T-cell ALL, and some cytogenetic abnormalities. Poor prognosis due to high early death rate secondary to leukostasis. The mechanisms at the origin of leukostasis are still poorly understood...

Nijmegen breakage syndrome (NBS) is a rare autosomal recessive chromosomal instability disorder characterized by microcephaly, immunodeficiency, radiosensitivity and a very high predisposition to malignancy. The gene responsible for the disease, NBS1, is located on chromosome 8q21 and encodes a protein called nibrin. After identification of the gene, a truncating 5 bp deletion, 657-661delACAAA, was identified as the disease-causing mutation in patients with the NBS. In this report, we describe two patients with NBS and T-lymphoblastic leukemia/lymphoma in a Macedonian family...

BACKGROUND: Optimizing patient selection is a necessary step to design better clinical trials. 'Life expectancy' is a frequent inclusion criterion in phase II trial protocols, a measure that is subjective and often difficult to estimate. The aim of this study was to identify factors associated with early death in patients included in phase II studies. METHODS: We retrospectively collected medical records of patients with advanced solid tumors included in phase II trials in two French Comprehensive Cancer Centers (Bordeaux, Center 1 set; Lille, Center 2 set)...

Acute myeloid leukemia (AML) involvement of the central nervous system is relatively rare, and detection of leptomeningeal disease typically occurs only after a patient presents with neurological symptoms. The case herein describes a 48-year-old man with relapsed/refractory AML of the mixed lineage leukemia rearrangement subtype, who presents with monocular vision loss due to leukemic eye infiltration. MRI revealed right optic nerve sheath enhancement and restricted diffusion concerning for nerve ischemia and infarct from hypercellularity...

The authors present a case of a 60-year-old male patient, previously diagnosed with B-cell chronic lymphocytic leukemia, who was admitted to the Emergency Room with dyspnea. The initial evaluation revealed severe anemia (Hgb = 5.0 g/dL) with hyperleukocytosis (800.000/µL), nearly all of the cells being mature lymphocytes, a normal chest X-ray and a low arterial oxygen saturation (89%; pulse oximetry). After red blood cell transfusion, Hgb values rose (9.0 g/dL) and there was a complete reversion of the dyspnea...

Infants with Down syndrome (DS) are at risk of developing a transient myeloproliferative disorder during the neonatal period, known as transient abnormal myelopoiesis (TAM). It is characterized by clonal myeloproliferation and is typically self-limiting. However, TAM can be a life-threatening disorder, when complicated by liver fibrosis. Here, we evaluated cytokine profiles in two male DS infants having TAM with or without liver dysfunction. The first patient, Patient 1, had hyperleukocytosis with cholestatic liver dysfunction, coagulopathy, and increased counts of blasts and was treated with exchange transfusion (ExT) due to the serious general condition...
