Abstract
BACKGROUND Recent studies have shown that patients diagnosed with coronarivus disease 2019 (COVID-19) and also with previous cardiovascular diseases have a higher mortality due to worsening heart disease. At the same time, patients without previous cardiovascular disease may also have cardiac complications. The aim of this multicenter study was to assess high sensitivity cardiac troponin T (hs-cTnT) in patients with COVID-19 and to evaluate the incidence of myocardial injury. METHODS In this multicenter study we enrolled 543 patients, 57.8% males, median age 63 years (range 18-99) from three selected hospitals: University Hospital Tor Vergata in Rome, Fondazione IRCCS Ca 'Granda Ospedale Maggiore Policlinico, in Milan, S Chiara Hospital in Trento. We measured hs-cTnT in all patients to assess myocardial injury and correlations with patient's age, symptoms and disease course. RESULTS The data showed that, among the 543 patients studied, 257 patients (47.3%) had hs-cTnT values higher than the upper reference limit (URL) of 14 ng/L. Patients with high hs-cTnT had more frequently fever (p < 0.01) and respiratory symptoms (p < 0.01), compared to the group with hs-cTnT values below URL. The results showed also that patients with hs-cTnT above URL had a higher frequency of previous cardiovascular disease (p < 0.01) as well as of hypertension (p < 0.01). Instead, among 231 patients with no previous cardiovascular disease, 81 (31.5%) had hs-cTnT values above the URL. Finally. the majority of the patients with high hs-cTnT were admitted to the intensive care unit (p < 0.01). CONCLUSION Our data suggest the assessment of high sensitivity cardiac troponin in patients with COVID-19 for early diagnosis of cardiac involvement.

Abstract
BACKGROUND High sensitivity cardiac troponins I (hs-cTnI) and T (hs-cTnT) and natriuretic peptides (BNP and NT-proBNP) are universally recognized as cardiac reference biomarkers in patients with acute coronary syndromes and heart failure respectively. However, while on one hand the high sensitivity methods of cardiac biomarkers have provided answers to fundamental pathophysiological and clinical questions in patients with heart disease, less information is available on their assessment in paraphysiological conditions, such as high intensity exercise in healthy athletes. The aim of this study was to evaluate hs-cTnI and NT-proBNP in highly trained runners after a 50 km ultramarathon. METHODS We have enrolled 20 highly trained male athletes who have run a 50 km ultramarathon. Blood samples were collected 2 hours before the start of the race (T0) and 20 minutes after the end of the race (T1). The blood concentrations of hs-cTnI and NT-proBNP measured before the race were within reference intervals in all runners. RESULTS Hs-cTnI significantly increased after the end of the race (median: 19 ng/L [IQR: 12.5-25.75] versus 6 ng/L [IQR: 4.25-8.0]; P<0.001), in three cases over the upper reference limit (URL) of 34 ng/L. NT-proBNP also significantly increased (median: 78 ng/L [IQR: 68.25-87.75] versus 22 ng/L [IQR: 18.25-26.75]; P<0.001). Three other athletes reached concentration over the URL (125 ng/L). CONCLUSIONS Our study showed a significant increase in hs-cTnI and NT-proBNP in highly trained athletes after a 50 km ultramarathon race, and 30% of runners had the values of cardiac biomarkers above URL. More studies with a larger number of athletes will be needed to better understand the effects of intense exercise on the heart of trained athletes.

Abstract
OBJECTIVE To date in Italy, there is paucity on data about the prevalence, clinical and haematological features of patients carrying the haemoglobin (Hb) Lepore variant in homozygous or in association with other haemoglobinopathies. METHODS Here we report the results of a retrospective analysis on 33 patients from Campania, a region of Southern Italy, historically followed at 'UOSD Malattie Rare del Globulo Rosso' of Cardarelli hospital, Naples, Italy. RESULTS We described 33 patients carrying the Hb Lepore variant: 21 compound heterozygotes with a common thalassaemia allele, six patients with homozygous state for Hb Lepore, five patients with Hb Lepore/Hb S and one patient with Hb Lepore/Hb Neapolis were identified. All individuals carried haplotype I or V. DISCUSSION These thalassaemic patients showed different phenotypes ranging from severe disease with early blood transfusion dependency to moderate form of thalassaemia intermedia. In most cases, thalassaemia mutation type determined the severity of the disease. CONCLUSION A great variability of clinical phenotype among the same genotypes was also observed suggesting the presence of unknown genetic modifiers acting in combination with Hb Lepore.

Abstract
BACKGROUND The mechanisms responsible for the sporadic occurrence of extramedullary haematopoiesis in polytransfused thalassaemic patients have not yet been clarified. In this study we tried to elucidate the influence of genotype and other factors on the presence of extramedullary haematopoiesis. MATERIALS AND METHODS We performed a retrospective database review of our polytransfused thalassaemic patients between January 2006 and December 2011. Demographic, transfusional, genetic, radiological and biochemical data were collected and statistically analysed. RESULTS Extramedullary haematopoiesis was found in 18 out of 67 patients (27%). All of them were splenectomised, had a higher nucleated red blood cell count and higher levels of the soluble form of transferrin receptor with respect to patients without extramedullary haematopoiesis; furthermore, patients with EMH had a lower transfusional iron intake and a higher pre-transfusion haemoglobin level as compared with those without extramedullary haematopoiesis. Ten out of the 18 patients with extramedullary haematopoiesis were compound heterozygotes for IVS 1-6/codon 39. A high frequency of thrombotic events was also recorded among all patients followed at our centre with this genetic profile. DISCUSSION Among our cohort of thalassaemic polytransfused patients, extramedullary haematopoiesis was not such a rare event. Furthermore, we identified a group of patients, most of whom were compound heterozygotes for IVS 1-6/codon 39, with increased soluble transferrin receptor levels and excessive expansion of erythroid marrow probably responsible for the tendency to develop extramedullary haematopoiesis.

Abstract
The study investigated the impact of gonadotropin-releasing hormone analogue (GnRH-a) on coagulation and fibrinolytic activities and its effectiveness in the prevention of pelvic adhesion after myomectomy. Thirty-two infertile women underwent myomectomy followed by adhesion evaluation surgery with a second-look laparoscopy. Before myomectomy, 15 women were treated with triptorelin acetate for 3 months and 17 received no treatment. Plasminogen activator inhibitor (PAI), thrombin activatable fibrinolysis inhibitor (TAFI), protein C (PC), plasminogen, α2-antiplasmin were determined by enzyme-linked immunosorbent assays and the activity of coagulation factors V and VIII by coagulometric methods. Patients treated with GnRH-a showed significant decrease in PAI, TAFI, factors V, and VIII (P < .05) and increased PC (P < .05), but no significant change in plasminogen and α2-antiplasmin levels compared with control group. The incidence, extent, and severity of adhesions were significantly lower in GnRH-a-treated patients compared with control group (P < .05), suggesting a possible critical role of the GnRH-a therapy in preventing postoperative adhesion development.

Abstract
OBJECTIVES The benefits of combined chelation therapy with daily deferiprone (DFP) and subcutaneous desferrioxamine (DFO) have been widely reported in literature. We retrospectively evaluated the efficacy of different schedules of combined chelation therapy and the incidence of adverse events. METHODS We evaluated 36 patients affected by thalassemia major treated with combined chelation therapy. Patients were subdivided into four treatment arms according to severity of iron overload and previous onset of adverse events to DFP therapy: Group 1 (13 pts) DFP 75 mg/kg per d plus DFO (25-35 mg/kg per d for 5 d); Group 2 (6 pts) DFP 50 mg/kg per d plus DFO (25-35 mg/kg for 5 d), Group 3 (10 pts) DFP 75 mg/kg per d plus DFO (25-35 mg/kg for 3 d), and Group 4 (7 pts) DFP 50 mg/kg per d plus DFO (25-35 mg/kg for 3 d). Change in serum ferritin level was evaluated in all patients. RESULTS Overall, ferritin decreased from 2592 +/- 1701 to 899 +/- 833 ng/mL (P < 0.001). All treatments were able to reduce ferritin levels, but in patients of group 1 and group 2 the highest mean decrease in serum ferritin level and the greatest improvement in liver iron concentration (LIC) and in T2* values were observed. CONCLUSIONS This study showed that the administration of DFO for 5 d a wk in combination with daily administration of DFP at 75 mg/Kg seemed to be the most efficacy and rapid method for reducing iron overload at liver and heart level. Furthermore, the use of different schedules of combined DFO and DFP administration was not associated with different incidence of adverse effects between the groups.

Abstract
In this review, the role of hypocholesterolaemia as a potential source of several clinical features of patients affected by thalassaemia is assessed. The primary focus is on the extent of the phenomenon among different forms of thalassaemia in order to highlight the particularly reduced level in patients with thalassaemia intermedia. In addition, we explore how the reduced levels of cholesterol could influence the atherogenic process and many typical clinical features of patients affected by thalassaemia.

Abstract
In this report we present a 37-year-old thalassemia patient with hyperferritinemia referred to our Microcytemia Centerat the beginning of deferasirox (DFX) therapy. Treatment with subcutaneous infusions of desferrioxamine (DFO) had started when he was 10 years old. During the 6-month DFX treatment, serum ferritin levels progressively increased from 600 to 2,700 ng/ml despite progressive DFX dose adjustments.This paradoxically abnormal ferritin levels required drug discontinuation but were not paralleled by a similar iron burden in T2 * magnetic resonance imaging. In this clinical case, ferritin levels were inappropriately increased following initiation of DFX treatment, but in the presence of an almost unmodified pattern of organ iron overload. Excluding the diagnostic dilemma of an improbable failure of DFX chelation, the pathogenesis of this phenomenon remains to be clarified, thus further complicating the problem of ferritin specificity and its role in monitoring chelation efficacy and in adapting DFX dosage in a limited period of treatment.

Abstract
BACKGROUND High oxygen-affinity haemoglobin variants and 2,3-diphosphoglycerate (2,3-DPG) deficiency are inherited diseases generating low tissue oxygen tension and erythropoietin-driven erythrocytosis, that characterizes the clinical phenotype of patients. Level of blood p50 (the oxygen tension at which haemoglobin is 50% saturated) is used to recognize these conditions. OBJECTIVES To define the clinical utility of blood p50 measurement in the diagnosis of isolated erythrocytosis. SUBJECTS AND DESIGN Venous blood p50 measurement was included in the diagnostic work-up of 102 consecutive patients with isolated erythrocytosis besides blood cell count, arterial oxygen saturation, serum erythropoietin measurement and screening for JAK2 mutations. SETTING Haematological Outpatient Section at University Hospital. RESULTS Seven patients had relative erythrocytosis. Among 95 patients with absolute erythrocytosis, 4 (4.2%) had decreased p50 level. The extended study of family members revealed a familial inheritance. Two families had haemoglobin variants already described as Haemoglobin Malmö and Haemoglobin San Diego. In one family, the proband had a new high oxygen-affinity haemoglobin variant (Haemoglobin Safi) resulting from the transversion C-->A at codon 81 of the alpha2-globin gene. In the last family, a deficiency of 2,3-DPG was found. Within the 91 patients with normal p50 values, 46 (51%) had secondary erythrocytosis, 13 (14%) polycythemia vera and 32 (35%) idiopathic erythrocytosis. CONCLUSIONS This study suggests that the investigation of blood p50 level may be useful to define diagnosis in patients with isolated erythrocytosis.

Abstract
This study describes a new molecular condition in the alpha(2)-globin gene (HBA2) found in six unrelated families from Southern Italy (Campania and Sicily). This new double mutant form of haemoglobin is called Hb Southern Italy and originated from the coexistence of two known mutations occurring in the same globin gene, HBA2 26 G-->A (Hb Caserta) and HBA2 130 G-->C (Hb Sun Prairie). Hb Sun Prairie was originally observed in Indian patients in either the homozygous state, with severe hemolytic anemia, and in the heterozygous state with microcytosis, or in asymptomatic cases as an alpha-thalassemia carrier phenotype. Hb Caserta was observed for the first time in a Casertian family (South Italy) that displayed a slowmigrating haemoglobin upon investigation. We report the clinical phenotype and molecular study of this new double mutant form of haemoglobin in heterozygous and homozygous subjects, as well as in association with alpha degrees delectional thalassemia.

Abstract
A high oxygen affinity hemoglobin (Hb) variant, Hb J-Cape Town [alpha92(FG4)Arg-->Gln (alpha1), CGG-->CAG] was identified in a 30-year-old woman patient from Cosenza (Southern Italy) who had previously been diagnosed with juvenile polycythemia in other hospitals. The occurrence of the variant Hb was assessed by both cation exchange chromatography and liquid chromatography-mass spectrometry (LC-MS) analyses. A detailed structural and functional characterization of the variant was performed at both the protein and DNA level. Structural investigation of the Hb variant by mass spectrometric methodologies and peptide sequencing identified the amino acid replacement as Arg-->Gln at alpha92. The corresponding DNA mutation CGGCAG was assigned to codon 92 of the alpha1 gene by DNA sequencing. These findings highlight the importance of investigating the hypothesis of a high affinity variant in the presence of a polycythemia so as to avoid unnecessary bone marrow examination or radioactive treatment. This report represents the first observation of the Hb J-Cape Town variant in Italy.

Abstract
Between January 1995 and December 2005, we conducted a screening program for the presence of Hb Neapolis, a rare abnormal Hb variant, in Campania, a region in Southern Italy. Nineteen patients with Hb Neapolis in heterozygosis and six patients with a genetic compound (Hb Neapolis/beta-thalassemia) were identified. Patients with Hb Neapolis in heterozygosis showed a slight alteration in HbA2 levels while compounds showed typical characteristics of thalassemia intermedia ranging from a non transfusion-dependent form for five patients to a transfusion-dependent form for one adult patient.

Abstract
An increased incidence of HFE gene mutations has been described in hematologic malignancies. In the present study, we investigated the allelic frequency of HFE gene mutations in 154 adult patients with acute leukemia (AL) [107 acute myeloid leukemia (AML), 20 acute promyelocytic leukemia (APL) and 27 acute lymphoblastic leukemia (ALL)]. The allelic frequency of the H63D mutation was 29% in AL patients and 25% in the healthy controls [P = 0.41; odds ratio (OR) = 1.20; 95% confidence interval (CI) = 0.77 - 1.93]. No difference was found between controls and AML or APL patients, whereas the H63D mutation was significantly more frequent in ALL than controls (44% vs. 25%, P = 0.04; OR = 2.37; 95% CI = 1.05 - 5.36). The overall comparison of the mutation among the three subtypes of AL demonstrated a higher allelic frequency in ALL (P = 0.02). In conclusion, our data demonstrate a correlation between the presence of the H63D mutation and the occurrence of ALL in adult patients.
