Since 1972, children affected by cancer took advantage from multi-centric diagnostic and therapeutic protocols produced by the Italian Association of paediatric haematology and oncology (AIEOP). At the beginning, these protocols were used in few well-trained centres, later in almost all Italian haemato-oncological centres. The need of a careful monitoring of his own activity induced AIEOP to achieve, in 1989, an Italian hospital- based registry (database Mod.1.01) of malignant tumours diagnosed and treated in the participating centres, with the aim to quantify the number of cases diagnosed and treated in the different centres, the agreement (or not) to official diagnostic- therapeutic protocols, and the extraregional migration. The database Mod.1.01, which is available via web to the current 55 AIEOP centres since 2000, recruits annually about 1,400 children (0-14 years) and 200 adolescents (15-19 years). While the first accounts for over 90% of expected subjects, the latter are only 25%. Leukaemias (30% of cases) are the most frequent childhood cancers, followed by central nervous system (CNS) tumours and lymphomas, 18% of cases both. In children, leukaemias (34%) are prevalent, mostly acute lymphoblastic leukaemia (26%), followed by CNS tumours (18%); in adolescents, lymphomas (30%) are prevalent, mostly Hodgkin lymphomas (22%), followed by bone sarcomas (16%). The recruitment of registered cases in AIEOP protocols is overall good both for children (70%) and for adolescents (60%), achieving outstanding results in leukaemia protocols. Extraregional migration of patients for diagnosis and therapy is decreasing over time, being currently about 20%, higher in adolescents, in solid tumours, and in residents in South Italy and in the islands. On the contrary, an increase of subjects born and resident abroad who are hospitalised in AIEOP centres for diagnosis and treatment, accounting at present for 5% of all cases, was observed. The results confirm that the database Mod.1.01 can be a valid tool able to contribute to epidemiologic research on childhood cancer in Italy.
Negli ultimi anni, vi e stata un’enorme spinta verso l’utilizzo della profilassi antimicrobica, secondo pratiche basate sull’evidenza, in circostanze quali la profilassi antifungina nei neonati estremamente prematuri e la profilassi antibiotica per la neutropenia associata alla chemioterapia. Tuttavia ci sono pochi dati riguardo la profilassi antibiotica nelle Immunodeficienze Primitive ed i regimi utilizzati variano tra i diversi Centri. Attualmente, la profilassi antibiotica e guidata dalla aumentata suscettibilita ai patogeni delle singole immunodeficienze e dall’esperienza acquisita in altre condizioni cliniche quali la fibrosi cistica, l’HIV e l’immunosoppressione post-trapianto. Con questo lavoro ci proponiamo di dare non solo un aggiornamento scientifico sull’utilizzo della profilassi antimicrobica nei principali disordini congeniti dell’immunita, ma anche una fotografia, per quanto parziale, di tale pratica nell’ambito del Network Italiano per le Immunodeficienze Primitive, nato nel 1999 in seno alla Associazione Italiana di Ematologia ed Oncologia Pediatrica (IPINet-AIEOP). Ulteriori studi sono necessari per individuare se, quando e come e opportuno avviare un regime profilattico efficace.
Using a Sendai Virus based vector delivering Yamanaka Factors, we generated induced Pluripotent Stem Cells (iPSCs) from peripheral blood mononuclear cells of a patient affected by Ataxia Telangiectasia (AT), caused by a novel homozygous deletion in ATM, spanning exons 5-7. Three clones were fully characterized for pluripotency and capability to differentiate. These clones preserved the causative mutation of parental cells and genomic stability over time (>100 passages). Furthermore, in AT derived iPSCs we confirmed the impaired DNA damage response after ionizing radiation. All these data underline potential usefulness of our clones as in vitro AT disease model.
Ataxia-telangiectasia (AT) is a neurodegenerative disorder characterized by ataxia, telangiectasia, and immunodeficiency. An increased risk of malignancies and respiratory diseases dramatically reduce life expectancy. To better counsel families, develop individual follow-up programs, and select patients for therapeutic trials, more knowledge is needed on factors influencing survival. This retrospective cohort study of 61 AT patients shows that classical AT patients had a shorter survival than variant patients (HR 5.9, 95%CI 2.0-17.7), especially once a malignancy was diagnosed (HR 2.5, 95%CI 1.1-5.5, compared to classical AT patients without malignancy). Patients with the hyper IgM phenotype with hypogammaglobulinemia (AT-HIGM) and patients with an IgG2 deficiency showed decreased survival compared to patients with normal IgG (HR 9.2, 95%CI 3.2-26.5) and patients with normal IgG2 levels (HR 7.8, 95%CI 1.7-36.2), respectively. If high risk treatment trials will become available for AT, those patients with factors indicating the poorest prognosis might be considered for inclusion first.
Background. Lacking protective antibodies, patients with Primary Antibody Deficiencies (PAD) suffer from frequent respiratory infections leading chronic pulmonary damage. Macrolides prophylaxis has been proven effective in chronic respiratory diseases, including chronic obstructive pulmonary disease, cystic fibrosis, and non-cystic fibrosis bronchiectasis. We aimed to test the efficacy and safety of orally administered low-dose azithromycin prophylaxis in PAD patients with chronic infection-related pulmonary diseases.
Ataxia-telangiectasia is a rare multisystem neurodegenerative genetic disorder due to mutation of ATM gene. The clinical expression and the immunological abnormalities are variable and apparently not associated with the type of ATM mutations. We report on two siblings affected by A-T with different clinical and immunological presentations; in particular in one the immunological phenotype was reminiscent of hyper IgM syndrome.
