Please click on the hyperlink in Additional Links fieldThis study compares allogeneic BMT with conventional chemotherapy for childhood ALL in second remission. Seventy-five children were transplanted between July 1981 and December 1995. For each patient two control patients matching the following criteria were selected from the Nordic database of ALL: (1) time of diagnosis, (2) T vs. non-T ALL, (3) site of relapse, (4) initial risk group, (5) sex and (6) relapse or =6 months after cessation of therapy. The minimal time of follow-up was 24 months. Mortality rate in CR2, leukemic relapse rate and the proportion in continued second remission were 16/75 (21%), 22/75 (29%) and 37/75 (50%), respectively. P2.-EFS for the BMT group was significantly better than that for the control group (0.40 vs. 0.23, P = 0.02). Children transplanted for bone marrow relapses in particular had a higher P2.-EFS (0.35 vs. 0.15 for the control group, P<0.01). Also, children grafted for early BM relapses had a higher P2.-EFS (0.32 vs. 0.11 for the control group P = 0.01). The outcome was similar when children were transplanted after early or late relapse. Also, there was no difference in outcome between the BMT and the chemotherapy group for children with late relapses. We conclude that allogeneic BMT with an HLA-identical sibling donor or other family donor should be performed in children relapsing in bone marrow during therapy or within 6 months of discontinuing therapy

Findings in familial haemophagocytic lymphohistiocytosis prior to symptomatic presentation

To access publisher full text version of this article. Please click on the hyperlink in Additional Links fieldFamilial haemophagocytic lymphohistiocytosis (FHL) is a rare, autosomal recessive disease of infancy and early childhood clinically characterized by fever, hepatosplenomegaly, lymphadenopathy, rash, neurological symptoms and icterus. Common laboratory findings include cytopenia, elevated liver enzymes, hyperbiliriubinaemia, hypofibrinogenaemia and hypertriglyceridaemia. The natural killer cell function is frequently decreased or absent. A diffuse lymphohistiocytic infiltration is seen in the reticuloendothelial system, often with haemophagocytosis. Molecular diagnosis is available in a minority of FHL families. Without adequate treatment and bone-marrow transplantation, the disease is fatal. A 6-wk-old child with FHL is presented. Shortly before the clinical onset of the disease, blood testing and bone-marrow examination had been carried out. All results were considered normal at that time. Conclusion: Blood tests and bone-marrow examination may be normal shortly before the clinical presentation and therefore do not exclude the diagnosis of FHL. There is a need for extended molecular diagnostic possibilities

Treatment-related deaths in second complete remission in childhood acute myeloid leukaemia

To access publisher full text version of this article. Please click on the hyperlink in Additional Links fieldThe frequency and causes of treatment-related deaths (TRD) in second complete remission (CR2) in acute myeloid leukaemia (AML) were investigated in a historical, prospective cohort study of 429 children included in the Nordic Society of Paediatric Haematology and Oncology (NOPHO)-AML-88 and -93 trials. Relapse occurred in 158 children (39%). Seventeen (18%) of the 96 patients entering CR2 suffered TRD. The main causes were infection (59%) and complications from graft-versus-host disease (22%). Fourteen (82%) of 17 TRDs occurred in children undergoing haematopoietic stem cell transplantations (HSCT). Optimal supportive care after HSCT is essential, and studies on risk factors for TRD are needed

Immunoglobulin class and subclass concentrations after treatment of childhood leukemia

To access publisher full text version of this article. Please click on the hyperlink in Additional Links fieldWith greatly increased survival rates after childhood leukemia during the last 3 decades, the long-term effects of the treatment have become more evident. The disease and its treatment impair the immune system, but the duration of this impairment is unknown. The authors studied the serum concentrations of immunoglobulins and IgG subclasses in 20 Icelandic children cured of leukemia on average 8 years and 3 months after their treatment ended. Although no marked deviations were found in the concentrations of the main immunoglobulin classes IgA, IgM, IgG, and IgE, the IgG subclass levels were below reference values. The patients had on average 0.9 of age standardized reference values of IgG1, 0.5 of IgG2, 0.8 of IgG3, and 0.7 of IgG4. However, none had any autoimmune diseases or a markedly increased tendency for infections. The results indicate that although the immunoglobulin classes regain their normal values within a few years after cessation of treatment, recovery of the IgG subclasses, especially IgG2, is impaired

Risk factors and outcome in ICU-acquired infections

To access publisher full text version of this article. Please click on the hyperlink in Additional Links fieldBACKGROUND: Nosocomial infections are common in intensive care units (ICU). The objectives of this study were to determine risk factors of ICU-acquired infections, and potential mortality attributable to such infections. METHODS: An observational study was performed in a 10-bed multidisciplinary ICU. For a period of 27 months, all patients admitted for >or=48 h were included. Infections were diagnosed according to Centers for Disease Control and Prevention definitions. Airway colonization was explored by molecular typing. Risk factors for infection were determined by multivariable logistic regression. Survival was analyzed with time-varying proportional hazards regression. RESULTS: Of 278 patients, 81 (29%) were infected: urinary tract infections in 39 patients (14%), primary bloodstream infections in 25 (9%), surgical site infections in 22 (8%) and pneumonia in 21 (8%). Of the total of 147 episodes, Gram-negative bacilli were isolated in 90, Gram-positive cocci in 49 and Candida sp. in 25. Risk factors for pneumonia were mechanical ventilation [odds ratio (OR=7.9, CI 1.8-35), lack of enteral nutriment (OR=8.0, CI 1.4-45) and length of time at risk (OR=1.8, CI 1.2-2.8), while gastric acid inhibitors did not affect the risk (OR=0.99, CI 0.32-3.0). Transmission of bacteria from the stomach to the airway was not confirmed. The risk of death was increased as patients were infected with pneumonia [hazard ratio (HR)=3.6; CI: 1.6-8.1], or primary bloodstream infection (HR=2.5; CI: 1.2-5.4), independent of age and disease severity. CONCLUSIONS: Mortality was increased by ICU-acquired pneumonia and primary bloodstream infections. Our findings did not support the gastro-pulmonary hypothesis of ICU-acquired pneumonia. The proposition that blood transfusions increase the risk of ICU-acquired nosocomial infections was not supported

Suspected infections in children treated for ALL

Please click on the hyperlink in Additional Links fieldAim: The aim of our study was to get epidemiological information on bacterial infections in children treated for ALL and to analyse which patients have an enhanced infection risk. Methods: Episodes of suspected or confirmed infections were evaluated during the first 12 months of treatment for childhood acute lymphoblastic leukaemia (ALL). Results: The number of patients was 73 (43 boys). The median age was 4.6 years. A total of 179 episodes occurred, varying from none in six patients to eight in one. Bacteria were cultured in 57 episodes (31.8%), the most common being coagulase-negative staphylococci. The number of episodes fell significantly with increasing age for suspected and confirmed infections (p < 0.001 and p = 0.03). The proportion of confirmed infections was significantly higher (p < 0.001) in the first episodes. The average number of suspected infections was higher in girls than in boys (p = 0.03), but confirmed infections were not. Conclusion: Most of the serious infections occur early in the treatment and the number of suspected and confirmed infections falls with age. Suspicion of infection is more likely in girls, but the number of confirmed infections is equal in both sexes. Coagulase-negative staphylococcus was most commonly isolated, highlighting the importance of careful handling of central venous devices
