Childhood autoimmune haemolytic anaemia ( AIHA) requires second-line immunosuppressive therapy in 30-50% of cases. It appears that rituximab is indicated in such circumstances. This prospective national study reports the practice, efficacy and tolerance of rituximab in children with isolated AIHA and AIHA in the setting of Evans syndrome ( ES). Sixty-one children were given rituximab between 2000 and 2014. The median interval from diagnosis to rituximab was 9·9 [interquartile range ( IQR) 1·6-28·5] months. Forty-six patients responded (75%) and the 6-year relapse-free survival ( RFS) was 48%. Twenty patients relapsed at a median interval of 10·8 ( IQR 3·9-18·7) months, rituximab allowed steroid withdrawal in 44/61 (72%) of children. In isolated AIHA, complete response and 6-year RFS were significantly higher than in ES ( P < 0·05). Ten out of 61 patients were infants, seven of who responded with a 6-year RFS of 71%. Among patients without immunoglobulin substitution before rituximab, 4 are still receiving substitutions. Five patients died, including one potentially attributable to rituximab. This large observational series of childhood AIHA established the rituximab benefit-risk ratio, allowing steroid withdrawal, with 37% of long-term responders, mainly in isolated AIHA. All subgroups of patients drew benefit. Our long-term results indicate the baseline to be challenged by new treatment approaches. [ABSTRACT FROM AUTHOR]

Background Most children with primary immunodeficiencies (PIDs) now reach adulthood. However, few studies have evaluated their health status and health-related quality of life (HRQoL). Objective To investigate long-term morbidity, the French Reference Center for PIDs initiated a prospective multicenter cohort: the French Childhood Immune Deficiency Long-term Cohort. The data collected were used to assess the physical health condition of patients who reached adulthood and the effect on their quality of life. Methods Patients were asked to complete health status questionnaires. A severity score (grade 1 [mild] to grade 4 [life-threatening]) was assigned to each health condition. The HRQoL of patients was compared with age- and sex-matched French normal values by using the 36-item Short-Form Survey (SF-36) HRQoL questionnaire. Results Among 329 participants, the mean age at evaluation was 27.6 years, with a 21-year mean follow-up after diagnosis; 43% reported at least 1 grade 4 health condition, and 86% reported at least 1 grade 3 (severe) or 4 health condition. Twenty-five (7.6%) patients had been treated for cancer. Compared with the French normal values, adults with PIDs scored significantly lower for all HRQoL domains. HRQoL was strongly associated with the burden of health conditions. The association with grade 4 or grade 3-4 health conditions was highly significant for all physical and mental domains. Conclusion Adults with PIDs diagnosed during childhood experienced a heavy burden of health conditions, which affected their HRQoL. Our results emphasize the need to closely monitor this vulnerable population. [ABSTRACT FROM AUTHOR]

Aim of the study: To evaluate the prognostic significance of the initial cerebro-spinal fluid (CSF) involvement of children with ALL enrolled from 1989 to 1996 in the EORTC 58881 trial. Patients and methods: Patients (2025) were categorised according to initial central nervous system (CNS) status: CNS-1 (CNS negative, n =1866), CNS-2 (<5 leucocytes/mm3, CSF with blasts, n =50), CNS-3 (CNS positive, n =49), TLP+ (TLP with blasts, n =60). CNS-directed therapy consisted in intravenous (i.v.) methotrexate (5g/sqm) in 4–10 courses, and intrathecal methotrexate injections (10–20), according to CNS status. Cranial irradiation was omitted in all patients. Results: In the CNS1, TLP+, CNS2 and CNS3 group the 8-year EFS rate (SE%) was 69.7% (1.1%), 68.8% (6.2%), 71.3% (6.5%) and 68.3% (6.2%), respectively. The 8-year incidence of isolated CNS relapse (SE%) was 3.4% (0.4%), 1.7% (1.7%), 6.1% (3.5%) and 9.4% (4.5%), respectively, whereas the 8-year isolated or combined CNS relapse incidence was 7.6% (0.6%), 3.5% (2.4%), 10.2% (4.4%) and 11.7% (5.0%), respectively. Patients with CSF blasts had a higher rate of initial bad risk features. Multivariate analysis indicated that presence of blasts in the CSF had no prognostic value: (i) for EFS and OS; (ii) for isolated and isolated or combined CNS relapse; WBC count<25×109/L and Medac E-coli asparaginase treatment were each related to a lower CNS relapse risk. Conclusions: The presence of initial CNS involvement has no prognostic significance in EORTC 58881. Intensification of CNS-directed chemotherapy, without CNS radiation, is an effective treatment of initial meningeal leukaemic involvement. [Copyright &y& Elsevier]

Abstract: From June 1989 through to November 1998, 121 children with newly diagnosed T-cell lymphoblastic lymphoma (T-LBL) were included in the EORTC 58881 trial conducted by the Children’s Leukaemia Group. The therapy regimen was based on a Berlin-Frankfurt-Munster protocol, for a total duration of 24 months. Cranial irradiation, prophylactic cranial and local, was omitted, even for patients with central nervous involvement at diagnosis. In total, 119 patients were evaluable. The median follow-up was 6.7 years. The overall event-free survival (EFS) rate at 6 years was 77.5% (standard error (SE)=4%). Median time of relapse was 1 year after complete remission (range 0.2–5.9 years). Only two (1.8%) patients had an isolated central nervous system relapse. For patients with complete response (n =16) to the 7-day prephase, the EFS rate at 6 years was 100% versus 14% (P <0.001) for patients with no response (n =7). Overall survival rate at 6 years was 86% (SE=3%). An intensive acute lymphoblastic leukaemia type chemotherapy regimen without irradiation leads to a high cure and survival rate in childhood T-LBL without an increased CNS recurrence. This suggests that prophylactic cranial irradiation can safely be omitted. Response to the prephase appeared to be a strong prognostic factor for EFS. [Copyright &y& Elsevier]
