ABSTRACT: Severe hyperlipidaemia with asparaginase therapy is rare. We report six cases, four of which developed significant problems with severe hyperlipidaemia during induction therapy for ALL and lymphoblastic lymphoma. The median triglyceride level was 22.3 mmol/L and the median cholesterol level was 12.3 mmol/L. None of the patients showed signs or symptoms of pancreatitis. Three children were re-exposed with Peg asparaginase, and one with Erwinia asparaginase, without recurrence of hyperlipidaemia or other symptoms. These cases highlight the dilemma in managing such rare cases of symptomatic hypertriglyceridaemia secondary to asparaginase and steroid therapy.

ABSTRACT: Acute lymphoblastic leukemia (ALL) remains one of the most common malignancies of childhood. Between April 1999 and August 2004, 9 of 207 patients treated at a Tertiary Oncology Service for ALL presented with Intracranial Hypertension (IH). Seven of the patients met the diagnostic criteria for Idiopathic Intracranial Hypertension (IIH). Four of the patients were treated with cerebrospinal fluid (CSF) drainage alone and four required Acetazolamide. Two of the four patients who were treated with Acetazolamide required subsequently a lumbar-peritoneal (LP) shunt. One patient succumbed to his disease before receiving any specific treatment.

ABSTRACT: Hepatic veno-occlusive disease (VOD) is a common (10-50%) and serious complication of haematological stem cell transplantation (HSCT), with up to 90% mortality rates. We carried out a study to assess whether the use of prophylactic defibrotide in paediatric patients undergoing HSCT results in a lower frequency or severity of hepatic VOD.
Forty-seven successive patients who underwent transplantation between April 2004 and December 2005 were given defibrotide prophylaxis and were compared with 56 historical controls transplanted between November 2001 and April 2004. No serious side effects were reported. High risk patients in the control group received ursodeoxycholic acid and tinzaparin as VOD prophylaxis. The groups were matched for sex, age, type of transplant and risk.
In the defibrotide group, four patients developed clinical VOD (Seattle criteria) although two had liver biopsies which showed graft versus host disease (GvHD). Defibrotide dose was increased and symptoms resolved within 14 days. Of the control group four patients had VOD. Two of these patients had reversed hepatic vein flow and died 30 days post-transplant, partly due to VOD. VOD was associated with busulfan conditioning (P = 0.001) and not with age, sex, type of transplant, GvHD, abnormal liver function prior to transplant or type of antifungal prophylaxis.
VOD incidence and severity was reduced in the defibrotide group which suggests that defibrotide might be effective in preventing and treating VOD. Sufficiently powered randomised trials are now required to definitively test the role of defibrotide in this setting.

ABSTRACT: A retrospective analysis of children with first relapse of acute lymphoblastic leukaemia (ALL), treated on the UKALL R2 protocol at four different hospitals, between June 1995 and December 2002 was performed. Of the 150 children 139 (93%) achieved a second complete remission. The overall survival (OS) and event-free survival (EFS) for the whole group was 56% and 47% respectively. The duration of first complete remission and immunophenotype, but not sites of relapse, were predictive for survival. Using the Berlin-Frankfürt-Münster risk stratification for relapsed ALL, the OS and EFS for standard, intermediate (IR) and high risk (HR) groups were 92% and 92%, 64% and 51%, and 14% and 15%, respectively; P < 0.0001 for both OS and EFS. In the IR group, those with a very early isolated central nervous system relapse also had a significantly worse outcome (P = 0.0001). Given the poor outcome of a second relapse, clear strategies are required to identify those in the IR group who will most benefit from stem cell transplantation (SCT). A higher proportion (16%) of induction failures in the HR group suggest the need for novel agents during this phase of treatment, but SCT was associated with a lower relapse rate and better outcome than those treated with chemotherapy alone.
