MYH9-related disease (MYH9-RD) is a rare autosomal-dominant disorder caused by mutations in the gene for nonmuscle myosin heavy chain IIA (NMMHC-IIA). MYH9-RD is characterized by a considerable variability in clinical evolution: patients present at birth with only thrombocytopenia, but some of them subsequently develop sensorineural deafness, cataract,(More)
In idiopathic thrombocytopenic purpura (ITP), corticosteroids have been widely recognized as the most appropriate first-line treatment, even if the best therapeutic approach is still a matter of debate. Recently, a single high-dose dexamethasone (HD-DXM) course was administered as first-line therapy in adult patients with ITP. In this paper we show the(More)
Inherited thrombocytopenias (ITs) are a heterogeneous group of syndromic and nonsyndromic diseases caused by mutations affecting different genes. Alterations of ACTN1, the gene encoding for α-actinin 1, have recently been identified in a few families as being responsible for a mild form of IT (ACTN1-related thrombocytopenia; ACTN1-RT). To better(More)
BACKGROUND The presenting features and treatment outcome of 120 patients with Down syndrome (DS) and childhood acute lymphoblastic leukemia (ALL) were compared with 6237 non-DS patients treated in the same years. METHODS We reviewed the database of 6 consecutive Italian Association of Pediatric Hematology and Oncology (AIEOP)-ALL trials conducted between(More)
Splenectomized patients are exposed to an increased risk of septicemia caused by encapsulated bacteria. Defense against infection is ensured by preformed serum antibodies produced by long-lived plasma cells and by memory B cells that secrete immunoglobulin in response to specific antigenic stimuli. Studying a group of asplenic individuals (57 adults and 21(More)
BACKGROUND Bernard-Soulier syndrome is a very rare form of inherited thrombocytopenia that derives from mutations in GPIbα, GPIbβ, or GPIX and is typically inherited as a recessive disease. However, some years ago it was shown that the monoallelic c.515C>T transition in the GPIBA gene (Bolzano mutation) was responsible for macrothrombocytopenia in a few(More)
BACKGROUND The eradication of Helicobacter pylori has been associated with remission of immune thrombocytopenia (ITP) in approximately half of eradicated patients. Data on children are limited to small case series. PROCEDURE Children from 16 centers in Italy, who were less than 18 years of age and diagnosed with chronic ITP (cITP), were screened for H.(More)
BACKGROUND Consensus guidelines for diagnosis and treatment of acute childhood idiopathic thrombocytopenic purpura (ITP) were published in 2000 by the Italian Association of Pediatric Haematology and Oncology (AIEOP). The assessment of guideline implementation was the primary objective of the present study. PATIENTS AND METHODS Information on each newly(More)
Acute idiopathic thrombocytopenic purpura (AITP) in children is generally a benign disease with a high frequency of spontaneous remission. Nevertheless the debate over treating or not is still open, because of the high risk of hemorrhage as long as the platelet count remains below 20 x 10(9)/l. We have retrospectively evaluated 120 pediatric cases from our(More)
