OBJECTIVE: To study the role of mid-induction (day 15) peripheral blood minimal residual disease (PBMRD) detection in pediatric B- lineage acute lymphoblastic leukemia (B-ALL). DESIGN: Prospective. SETTING: Tertiary care center. PATIENTS: Forty consecutively diagnosed treatment naive, pediatric B-ALL patients. INTERVENTION: National Cancer Institute (NCI) standard risk patients were given three drug induction regimen comprising vincristine, L-asparginase and prednisolone; NCI high risk patients were supplemented with daunorubicin...

BACKGROUND: The management of hyperleukocytosis currently involves intensive supportive care for preventing tumor lysis syndrome (TLS)-associated metabolic abnormalities as well as cytoreduction procedures to reduce the white blood cell (WBC) count. These procedures are often equipment-intensive and may not be practised in developing countries with limited resources. Hence, it is not clear what would be the most effective strategy to manage hyperleukocytosis and prevent TLS. PROCEDURE: All children ≤12 years, diagnosed with acute lymphoblastic leukemia (ALL) and hyperleukocytosis (WBC count >100 × 10(9)/l) were administered L-asparginase (L-asp, 6,000 U/m(2), i...

L-asparaginase is an important drug in the treatment of childhood acute lymphoblastic leukaemia (ALL). Treatment is associated with several toxicities, including acute pancreatitis. Clinical course, presentation, re-exposure to L-asparginase after pancreatitis and risk of recurrent pancreatitis within an asparaginase-intensive protocol has been poorly reported. Children (1-17 years) on the ongoing Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol with asparaginase-associated pancreatitis (AAP) diagnosed between 2008 and 2012 were identified through the online NOPHO ALL toxicity registry...

L-Asparginase is a frequently used drug in hematological malignancies. Various side effects associated with its use include hypersensitivity, hyperglycemia, hypercoaguability and acute pancreatitis. We describe a rare complication of pancreatic pseudocyst in a 12 year old boy of Acute lymphoblastic leukemia (ALL) treated with MCP-841 protocol (during re-induction phase). Nearing the end of induction i.e. day 25, patient complained of a painful swelling in the epigastrium and left hypochondrium. Investigations revealed a pancreatic pseudocyst for which he underwent cystojejunostomy...

L-Asparginase is used for remission induction in acute lymphoblastic leukemia. We describe a case of 16-year-old boy who developed cortical venous thrombosis following the administration of L-Asparginase.

A 5-year-old, castrated male mixed-breed dog was presented for paraparesis, ataxia, hyperesthesia, and thrombocytopenia of 5 months' duration and recurrent seizures during the preceding 2 weeks. Multifocal neurological, ophthalmological, pulmonary, and cardiac diseases were identified. Magnetic resonance imaging and cerebrospinal fluid analysis supported a tentative diagnosis of neoplastic or inflammatory disease. A computed tomography-guided biopsy provided both cytopathological and histopathological evidence of intravascular lymphoma...

COMPARATIVE STUDY
T Rodriguez, E Baumgarten, R Fengler, D Soumpasis, G Henze
Nine children of the ALL-REZ BFM 87 and 90 trial received L-Asparginase (L-ASP) as a continuous infusion for 48-72 hs (i.e. 25 therapy cycles). Seven patients had had an allergic reaction towards an i.m. application (i.m., 29 therapy cycles). Two further patients got L-ASP initially as continuous infusion. The i.m. applications were carried out 19 times with Erwinia and 10 times with E. coli-Asparaginase, the continuous infusions 15 times with Erwinia and 10 times with E. coli-Asparaginase. In case of four patients continuous infusions of the same L-ASP type (E...

Immobilized asparaginase was prepared by embedding asparaginase (which is effective for remission in children with leukemia) into fibrin polymer formed by fibrinogen-fibrin conversion in the presence of thrombin. The immobilized asparaginase film did not dissolve in 6 mol/1 urea, suggesting that blood coagulation factor XIII participates in the cross-linking between fibrins and between fibrin and asparaginase.

S Plesnicar, R Merolla, R Golouh, D Micu, G Astaldi
Administration of L-asparaginase may cause remission in a high percentage of acute lymphocytic leukemias and lymphomas, either in experimental animals or in human beings. This enzyme is able to depress immune reactions like lymphocyte blastogenesis and delayed hypersensitivity, and to impair gamma-globulin synthesis. L-asparaginase also has antigenic properties, and may cause the formation of anti-L-asparaginase antibodies. This study reports observations on the effect of L-asparginase on the 7S gamma-globulin levels and on the behaviour of the germinal centers in spleen and lymph nodes...

Recurrence of childhood acute lymphoblastic leukemia occurs in about 30-50% and indicates irresistable progression of the disease. While systemic (= hematologic) relapse is due to drug resistance of leukemic cells, pharmacologic barriers may be responsible for local relapses as meningeal involvement, leukemic ophthalmopathy or testicular infiltration. L-asparginase seems to be an important component of drug combinations for re-induction therapy for systemic relapse. Following reinduction therapy modification of continuation therapy is necessary...
