Haemostatic activation in HIV infected patients treated with different antiretroviral regimens.

HIV infected patients treated with highly active antiretroviral therapy (HAART) may be at increased risk of cardiovascular events, particularly if based upon the use of protease inhibitors (PI). We investigated the haemostatic markers of cardiovascular risk in 115 HIV infected subjects, divided into four groups : 1) patients naïve to antiretroviral therapy (Naïve; n=34 patients), or subjects that had been on a stable combination therapy for > or =12 months with either: 2) double reverse transcriptase nucleoside analogue inhibitors therapy (2NRTI; n=26), 3) 2NRTI backbone plus a non-nucleoside analogue reverse transcriptase inhibitor (NNRTI; n=27), and 4) on a PI based regimen (PI; n=28). Forty-four healthy subjects were included as controls.

Strategies for the transfusion of subjects with complex red cell immunisation: the Bank of rare blood donors of the Region of Lombardy.

Introduction: Selecting units of rare blood for transfusion to patients with complex immunisation is one of the most critical processes of a Transfusion Centre. In January 2005 the 'Rare Blood Components Bank - Reference Centre of the Region of Lombardy' w as established with the following goals: 1) identifying regional rare blood donors; 2) creating a regional registry of rare donors; 3) organising a regional bank of liquid and frozen rare blood units; 4) setting up a regional Immunohaematology Reference Laboratory (IRL) to type donors and resolve complex cases.

Methods: The key elements in establishing the Bank were periodic meetings organised by the directors and representatives of the regional Departments of Transfusion Medicine and Haematology (DTMH) and the institution of three working groups (informatics, regulations, finance).

High prevalence of a screening-detected, HFE-unrelated, mild idiopathic iron overload in Northern Italy.

Background And Objectives: In Italy, typical HFE mutations account for only 64% of the cases with overt hereditary hemochromatosis (HH), and a common HFE-unrelated disease was hypothesized.

Design And Methods: One thousand and fifty potential blood donors were screened by iron tests, C282Y and H63D HFE mutation analysis in a region in North Italy. Subjects with repeated fasting transferrin saturation of 45% or more and no secondary iron overload were defined as probands with idiopathic iron overload.
