Trombosis is seen in children with acute lymphoblastic leukemia during or after L-asparaginase treatment. Posterior reversible encephalopathy syndrome (PRES) is a complex syndrome characterized with sudden hypertension, headache, nausea, vomiting, alteration in the state of consciousness, vision defect and seizures. The cases related to this syndrome have been reportedly seen after eclampsia, organ transplantation, immunsuppressive treatments, autoimmune diseases and chemotherapy. Vasogenic edema occuring in the brain parencyhma constitues the basic pathophysiology. We present a case who developed seizures during treatment for B-cell acute lymphoblastic leukemia and diagnosed as posterior reversible encephalopathy.

Erwinia chrysanthemi-derived asparaginase is increasingly integral to acute lymphoblastic leukemia therapy. In our series, 16% of patients developed symptomatic hyperammonemia following Erwinia administration with symptoms including refractory nausea, vomiting, profound fatigue, malaise, and coma. This series of patients receiving Erwinia indicates higher than expected incidence of hyperammonemia, correlation between ammonia and asparaginase levels and therapeutic asparaginase activity levels despite dose reduction. The series provides evidence for investigation into which patients require intervention to prevent toxicity, which patients may have ammonia levels used as an asparaginase activity surrogate and which patients may achieve equivalent efficacy with abridged dosing.

L-Asparaginase has significantly improved outcome for children with acute lymphoblastic leukemia and has become an essential component of multiagent chemotherapy. However, there are many adverse events due to L-asparaginase, including acute pancreatitis. The pathology of L-asparaginase-associated pancreatitis (AAP) remains unclear. We compared patients who developed AAP (n=29) and random matched controls (n=36) who had been enrolled in the Japan Association of Childhood Leukemia Study of the ALL-02 protocol. AAP and control patients were matched for age, sex, treatment, and protocol risk. We examined correlations between AAP development and clinical symptoms, laboratory data, and concomitant medication. Abdominal pain and nausea were common presenting symptoms for AAP. There was an increased risk of AAP in patients using gastric acid-suppressing agents and antithrombin (AT) supplementation. Mean fibrinogen and AT levels before the onset of AAP were lower in AAP patients than in controls. Decreased AT and fibrinogen levels resulting from the strong suppression of protein synthesis by L-asparaginase were predictive signs for AAP. Our epidemiological approach should prove clinically useful for the diagnosis the AAP as early as possible.
