IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.
AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.
EnglishSevere thrombocytopenia (TP) accounted for 5.3% of cases in a consecutive series of 380 HIV-infected intravenous drug users (IVDUs) at presentation. Forty-one of 53 subjects with severe TP showed haemorrhages and were treated as follows: ten were splenectomized, 17 were given high-dose intravenous immunoglobulins (HDIg), and 10 received anti-Rh(D) immunoglobulins (anti-Rh Ig). Splenectomy induced a complete clinical response in all cases: four out of 10 patients maintained platelet counts greater than 100 x 10(9)/l. HDlg gave a good clinical response in all patients, but eight out of 17 suffered haemorrhages during the follow-up and recall treatments were necessary. Six out of 10 patients treated with anti-Rh lg maintained platelet counts greater than 30 x 10(9)/l, but in two cases the treatment was interrupted because of severe haemolysis. No patient progressed to overt AIDS during the follow-up. Splenectomized patients in particular did not show adjunctive risks of worsening of the HIV-related clinical picture. A platelet kinetic study performed in 20 patients with severe HIV-related TP suggests a possible role for platelet sequestration in TP of HIV-infected IVDUs, in which a liver involvement is very frequent.
