REVIEW
Anand Padmanabhan
Cellular collection is an important and increasingly used apheresis procedure. These collections are performed by leukocytapheresis, a procedure involving the removal of a patient's or donor's white blood cells, and are used to collect hematopoietic progenitor cells, specific cell populations (such as T-lymphocytes), and granulocytes. Hematopoietic progenitor cell apheresis and T-lymphocyte collection are performed by procedures that enrich for mononuclear cells. Hematopoietic progenitor cells are used for autologous and allogeneic hematopoietic stem cell transplantation, whereas T-cell collection is being used increasingly in novel cellular therapy approaches and for donor lymphocyte infusions to induce graft-versus-leukemia effect...

BACKGROUND: Hyperleukocytosis is a serious, life-threatening complication of pediatric acute leukemia that can cause neurologic injury, pulmonary leukostasis, metabolic derangements, and coagulopathy. Acute leukemia has the highest risk of mortality and morbidity at presentation when associated with hyperleukocytosis. Infant leukemia presents unique challenges and treatment considerations due to the disease itself and size and overall health of the patient. While medical management of hyperleukocytosis in older patients with acute leukemia has been described, including cytoreductive procedures with automated leukapheresis (AL) or manual whole blood (WB) exchange transfusion, very little data exist for standardized management of hyperleukocytosis in infant leukemia patients...

BACKGROUND AND OBJECTIVE: Pulmonary embolism is potentially life-threatening in patients with lung cancer, but the clinical studies on patients with lung cancer having asymptomatic pulmonary embolism were barely reported. METHODS: Clinical data of patients with lung cancer were obtained from the Department of Respiratory and Critical Care Medicine of Tianjin Chest Hospital during July 2012 and June 2015 and were reviewed retrospectively. A total of 28 patients with lung cancer having pulmonary embolism (LP group) were enrolled, and another 56 cases with lung cancer alone (LC group) were enrolled as controls...

We report the outcome of 27 children with de novo acute megakaryoblastic leukemia (AMKL) (excluding Down syndrome) enrolled in the French multicenter prospective study ELAM02 (2005-2011). There was no difference in gender, initial leukocyte count, CNS involvement, and complete remission rate (88.9%), as compared to other acute myeloid leukemia (AML) subtypes. AMKL patients had a significantly poorer outcome (5-year overall survival 54% [CI 95% 33%-71%] than children with other AML subtypes (5-year overall survival 73% [CI 95% 68%-77%] p = 0...

BACKGROUND/OBJECTIVES: Childhood acute myeloid leukemia (AML) is a rare and heterogeneous disease. Pediatric data on the epidemiology of acute kidney injury (AKI) in AML are limited. We report on the incidence of AKI in childhood AML and the risk factors associated with AKI episodes. METHODS: A retrospective cohort of 53 patients (≤18 years), with de novo AML, receiving chemotherapy over a 10-year period. All serum creatinine (SCr) levels during therapy-related hospitalizations were assessed to stage AKI episodes as per Kidney Disease: Improving Global Outcomes criteria...

BACKGROUND: Chronic myeloid leukemia (CML) is a common hematologic malignancy; however, its occurrence during pregnancy is unusual due to its low prevalence in females of childbearing age. There are conflicting reports of how to best manage CML in pregnancy, particularly in the setting of leukocytosis. CASE REPORT: A 30-year-old female was diagnosed with CML at 18 weeks' estimated gestational age. On initial presentation she reported fatigue, night sweats, and early satiety, and was found to have a white blood cell (WBC) count of 69...

A 16-year-old boy was incidentally found to have hyperleukocytosis during a school physical examination. He was diagnosed with atypical chronic myeloid leukemia in chronic phase. Although treatment with hydoxyurea was started, his white blood cell count increased and he eventually developed lethal intracranial hemorrhage. Although very rare, intracranial hemorrhage should be considered as a possible complication in patients with atypical chronic myeloid leukemia, even in chronic phase, if they have hyperleukocytosis and thrombocytopenia...

Acute lymphoblastic leukemia is the most common (77%) childhood leukemia and also the most common neoplastic disease in children. Acute lymphoblastic leukemia initially present with hyperleukocytosis (WBC count more than 50,000/mm³) in twenty percent cases. These children are particularly at risk of development of tumor lysis syndrome (TLS). Tumor lysis syndrome is a metabolic disorder consists of hyperuricaemia, hyperkalemia, hyperphosphataemia, hypocalcaemia with or without renal insufficiency. It is the most common disease related emergency encountered by physicians caring for cancer of children and adult...

Esophageal stricture is a major secondary complication of ingesting caustic agents. We examined our experiences with caustic injuries with a view to finding clinical and biological risk factors of esophageal strictures secondary to caustic ingestion. Records were retrieved for 58 adults admitted consecutively to our intensive care unit for caustic ingestion. Fifty cases were managed conservatively and therefore retained for analyses. Patients were grouped according to whether they developed strictures or not during the follow-up period...

BACKGROUND: Hyperleukocytosis, defined as white blood cell (WBC) count above 100 × 109 /L, has high early morbidity and mortality from leukostasis-related complications, namely intracranial hemorrhage and pulmonary distress. Initiating chemotherapy without prior leukocytoreduction may lead to tumor lysis syndrome (TLS). Therapeutic leukocytapheresis (TL) is used as one leukocytoreductive intervention; however, its safety and efficacy in pediatric leukemia has not been established. The purpose of this study is to evaluate safety of TL in pediatric patients and assess the efficacy of TL in reducing WBC count in pediatric leukemia...

The application of apheresis equipment to perform leukapheresis (LK) in low weight paediatric patients is logistically complex and lacking of largest clinical performing experiences, meanwhile, the benefit from LK is controversial. In this study, 15 children with acute lymphoblastic leukemia(ALL)and acute myeloid leukemia (AML) and hyperleukocytosis were treated with the COBE Spectra apheresis system in the general paediatric ward by the staff from the department of Blood Transfusion. 26 LK procedures were performed...

Hyperleukocytosis (HL) is defined as the clinical condition when the white blood cell (WBC) count is above 100,000/mm(3) in peripheral blood. It has been already shown in the literature that leukapheresis, a conventional technique to decrease the serum WBC level, is ineffective for long-term survival in cases of hyperleukocytotic acute myeloid leukemia (AML) with leukostasis. However, the effect of leukapheresis on early mortality is still unclear. In this study, we aimed to evaluate the effect of leukapheresis on early mortality of patients with AML who have HL...

BACKGROUND: Hyperleukocytosis, a peripheral white blood cell count greater than 100,000/mm3,is most commonly seen in patients with newly diagnosed or relapsed acute lymphoblastic leukemia and acute myeloid leukemia. Leukostasis is a reduction in blood flow related to hyperviscosity. Hyperleukocytosis, causing leukostasis, is an oncologic emergency and requires an exacting assessment and rapid response with appropriate intervention to prevent morbidity and mortality in the first week after diagnosis...

RATIONALE: Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma (NHL). The most common extranodal sites of ALCL are skin, subcutaneous tissue, bone, lung, and gastrointestinal organs. This study reports a case of ALCL with multiple extranodal involvement, especially the whole body skeletal muscles, with the aim to share the imaging features of the ALCL including magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT)...

Chronic granulomatous disease (CGD) is a rare primary immune deficiency caused by mutations in genes coding for components of the nicotinamide adenine dinucleotide phosphate oxidase, characterized by severe and recurrent bacterial and fungal infections, together with inflammatory complications. Dysregulation of inflammatory responses are often present in this disease and may lead to granulomatous lesions, most often affecting the gastrointestinal (GI) and urinary tracts. Treatment of inflammatory complications usually includes corticosteroids, whereas antimicrobial prophylaxis is used for infection prevention...

INTRODUCTION: Hyperleukocytosis (HL) and leukostasis seen in myeloid leukemias are a medical emergency. We present a case series of ten such patients in a 4-year period. Sixteen therapeutic leukocyte reduction (TLR) were done in ten cases along with other supportive measures. The American Society for Apheresis supports the routine implementation of TLR in cases of HL secondary to myeloid leukemias with signs of leukostasis. MATERIALS AND METHODS: The procedures were performed on the intermittent flow cell separator after discussion with the treating physician about patient's condition...
