Acquired aplastic anemia (AA) is a rare heterogeneous disease characterized by pancytopenia and hypoplastic bone marrow. The incidence is 2-3/million inhabitants/year, in Europe, but higher in East Asia. Survival in severe aplastic anemia (SAA) has markedly improved in the past 2. decades because of advances in hematopoietic stem cell transplantation, immunosuppressive and biologic drugs, and supportive care. In SAA hematopoietic stem cell transplant (HSCT) from a matched sibling donor (MSD) is the treatment of choice. If a MSD is not available, the options include immunosuppressive therapy (IST) or unrelated donor HSCT. The objective of this guideline is to provide healthcare professionals with clear guidance on the diagnosis and management of pediatric patients with AA. A preliminary, evidence-based document issued by a group of pediatric hematologists was discussed, modified and approved during a series of "Consensus Conferences" according to procedures previously validated by the AIEOP Board. The guidelines highlight the importance of referring pediatric patients with AA to pediatric centers with long experience in diagnosis, differential diagnosis, management, supportive care and follow-up of AA. © 2015.

In the last two decades great improvements have been made in the treatment of childhood acute lymphoblastic leukemia, with 5-year overall survival rates currently approaching almost 90%. In comparison, results reported in adolescents and young adults (AYAs) are relatively poor. In adults, results have improved, but are still lagging behind those obtained in children. Possible reasons for this different pattern of results include an increased incidence of unfavorable and a decreased incidence of favorable cytogenetic abnormalities in AYAs compared with children. Furthermore, in AYAs less intensive treatments (especially lower cumulative doses of drugs such as asparaginase, corticosteroids and methotrex-ate) and longer gaps between courses of chemotherapy are planned compared to those in children. However, although favorable results obtained in AYAs receiving pediatric protocols have been consistently reported in several international collaborative trials, physicians must also be aware of the specific toxicity pattern associated with increased success in AYAs, since an excess of toxicity may compromise overall treatment schedule intensity. Cooperative efforts between pediatric and adult hematologists in designing specific protocols for AYAs are warranted. © C. Rizzari et al., 2014. Source

Childhood multicentric Castleman disease (MCD) is a rare and unexplained lymphoproliferative disorder. We report a human herpesvirus- 8 (HHV-8)-infected child, born to consanguineous Comorian parents, who displayed isolated MCD in the absence of any known immunodeficiency. We also systematically review the clinical features of the 32 children previously reported with isolated and unexplained MCD. The characteristics of this patient and the geographic areas of origin of most previous cases suggest that pediatric MCD is associated with HHV-8 infection. Moreover, as previously suggested for Kaposi sarcoma, MCD in childhood may result from inborn errors of immunity to HHV-8 infection. Copyright © 2012 by the American Academy of Pediatrics. Source

This document updates and expands the recommendations on primary prophylaxis of invasive fungal diseases (IFD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients, published in 2009 by the Gruppo Italiano Trapianto Midollo Osseo (GITMO). A consensus process was undertaken to describe and evaluate current information and practice regarding risk stratification and primary antifungal prophylaxis during the pre-engraftment and postengraftment phases after allo-HSCT. The revised recommendations were based on the evaluation of recent literature including a large, prospective, multicenter epidemiological study of allo-HSCT recipients conducted among the GITMO transplantation centers during the period of 2008 to 2010. It is intended as a guide for the identification of types and phases of transplantation at low, standard, and high risk for IFD, according to the underlying disease, transplantation, and post-transplantation factors. The risk stratification was the critical determinant of the primary antifungal approach for allo-HSCT recipients. © 2014 American Society for Blood and Marrow Transplantation. Source

Background. About 10% of pediatric patients with invasive pneumococcal disease (IPD) die from the disease. Some primary immunodeficiencies (PIDs) are known to confer predisposition to IPD. However, a systematic search for these PIDs has never been carried out in children presenting with IPD. Methods. We prospectively identified pediatric cases of IPD requiring hospitalization between 2005 and 2011 in 28 pediatric wards throughout France. IPD was defined as a positive pneumococcal culture, polymerase chain reaction result, and/or soluble antigen detection at a normally sterile site. The immunological assessment included abdominal ultrasound, whole-blood counts and smears, determinations of plasma immunoglobulin and complement levels, and the evaluation of proinflammatory cytokines. Results. We included 163 children with IPD (male-to-female ratio, 1.3; median age, 13 months). Seventeen children had recurrent IPD. Meningitis was the most frequent type of infection (87%); other infections included pleuropneumonitis, isolated bloodstream infection, osteomyelitis, endocarditis, and mastoiditis. One patient with recurrent meningitis had a congenital cerebrospinal fluid fistula. The results of immunological explorations were abnormal in 26 children (16%), and a PID was identified in 17 patients (10%), including 1 case of MyD88 deficiency, 3 of complement fraction C2 or C3 deficiencies, 1 of isolated congenital asplenia, and 2 of Bruton disease (X-linked agammaglobulinemia). The proportion of PIDs was much higher in children aged >2 years than in younger children (26% vs 3%; P <. 001). Conclusions. Children with IPD should undergo immunological investigations, particularly those aged >2 years, as PIDs may be discovered in up to 26% of cases. © 2014 The Author 2014.
