Migration has impacted the spread of thalassaemia which is gradually becoming a global health problem. Italy, with an approximate estimation of 7,000 patients, does not have an accurate national record for haemoglobinopathies. This cross-sectional evaluation includes data for approximately 50% of beta-thalassaemia patients in Italy to provide an overview of the burden of thalassaemia syndromes.

The analysis included data on epidemiology, transfusions and clinical parameters from 3,986 thalassaemia patients treated at 36 centres in Italy who were alive on 31

December 2017. APX115 The study used WebThal, a computerised clinical record that is completely free-of-charge and that does not have any mandatory fields to be filled.

For patients with thalassaemia major, 68% were aged ≥35 years and 11% were aged ≤18 years. Patients with thalassaemia intermedia were slightly older. Transfusion data, reported in a subgroup of 1,162 patients, showed 9% had pre-transfusion haemoglobin <9 g/dL, 63% had levels between ≥9 and <10 g/dL, and 28% had levels ≥10 g/dL. These 1,162 patients underwent 22,272 transfusion days during 2017, with a mean of 19 transfusion days/year/patient (range 1-54 days). Severity of iron overload was reported in 756 patients; many had moderate or mild liver iron load (74% had liver iron <7.5 mg/g dry weight). In the same cohort, 85% of patients had no signs of cardiac iron load (MRT2* >20 ms), and only 3% showed signs of high-risk heart condition (T2* <10 ms). Most patients had normal alanine amino transferase levels due to treatment with the new anti-hepatitis C virus (HCV) drugs.

This study provides an overview of the current health status of patients with thalassaemia in Italy. Moreover, these data support the need for a national comprehensive thalassaemia registry.

For neonates and preterm infants, in whom a transfusion dose is low, the use of red blood cells (RBC) from cord blood appears to be feasible. Standardisation of fractionation and identification and assessment of quality control parameters for such RBC are still lacking.

We describe the process used to obtain RBC from cord blood for transfusion purposes, including quality controls to evaluate fractionation performance and the effects of storage. The cord RBC, to which SAG-M was added, were sampled on the day of fractionation, and 7 and 14 days (end of storage) later in order to measure the complete blood count, biochemical parameters and residual white blood cells. We also assessed microbial contamination.

Data relative to 279 cord blood units were evaluated. The median gestational age at collection was 40 weeks (interquartile range [IQR] 39.1-40.7) and the median volume was 90 mL (IQR 81-103). Units were subjected to automated fractionation with Compomat, and packed RBC were suspended in SAG-M solution.transfusion dose and quality of the units appear safe and suitable for clinical use in neonates, with a satisfactory haematocrit and residual white blood cell content, despite a very variable collection volume.

Red blood cells (RBC) are subject to oxidative stress by reactive oxygen species (ROS) during storage. Molecular characterisation of oxidative stress in stored RBC, which may also occur in other blood components during long periods of storage, is rare.

Our study included 45 healthy RBC donors recruited in Brazil. Blood was collected into standard Grifols

Triple Bags containing CPD SAG-M. Haematological values, biochemical data, and oxidative stress markers were assessed weekly during storage until 42 days after collection. GSTM1 and GSTT1 were determined by multiplex-polymerase chain reaction (PCR), while GSTP1 rs1695 and rs1871042, CAT rs1001179, and SOD2 rs4880 were evaluated by real-time PCR.

A direct proportional relationship was found between storage time and levels of ROS and thiobarbituric acid reactive substances (TBARS, indicators of lipid peroxidation) (p<0.001). These parameters were indirectly proportional to ABTS values (p<0.001). The plasma concentration of TBARS was associated witweeks of storage. We observed an association between elevated TBARS levels and the presence of GSTP1 and SOD2 variants in stored RBC. Although notable for heterozygous variants, this association was even stronger for the homozygous variants GSTP1 rs1695 (303GG), GSTP1 rs1871042 (-16TT), and SOD2 rs4880 (47TT). These findings accentuate the importance of genetic factors in storage lesions and will expand our understanding and consideration of endogenous and exogenous causes in improving clinical treatment with blood transfusions.

Platelet transfusion plays a critical role in the supportive treatment of acute leukaemia patients who receive chemotherapy and haematopoietic stem cell transplantation (HSCT). There are few studies assessing appropriateness of platelet transfusion in this population. An audit was conducted to determine how appropriately platelets are transfused in acute leukaemia patients at a tertiary care health institution.

A six-year retrospective audit was conducted in acute lymphoblastic (ALL) and acute myeloid leukaemia (AML) patients in an Academic Centre. Episodes were assessed as either appropriate or inappropriate based on guidelines from the British Society for Haematology (BSH). Pre-transfusion platelet count, transfusion indication, World Health Organization (WHO) bleeding score, and antibiotic use were all documented.

Overall, 745 platelet transfusion episodes in 154 patients were audited. The proportion of episodes appropriately indicated according to BSH guidelines was 75.3%. Paediatrics and Internal Mo optimise its utilisation and patient outcome.

Anaemia is a common finding in the preoperative setting, affecting around one-third of patients for whom major surgery is programmed. Moreover, preoperative anaemia has been shown to worsen patient outcome and increase length of hospital stay and costs. In the field of preoperative anaemia correction, a recent Consensus statement suggested reviewing the classic World Health Organization (WHO) criteria in adults by aligning the haemoglobin cut-off to 13 g/dL for both genders. The aim of our study was to assess the differences in terms of prevalence, transfusion rate, transfusion trigger, and blood losses according to gender in a mixed population of surgical patients.

We reviewed data of 610 consecutive patients undergoing elective major surgery at a tertiary care hospital during a 9-month period. Transfusion rate and transfusion triggers were recorded, analysed and stratified by haemoglobin class, with a particular focus on the 12.0-12.9 g/dL range.

Since the anaemia threshold was redefined at 13 g/dL for both genders, its prevalence rose from 26.
