Abstract
A hypercoagulable state has been described in thalassemia patients, partly due to a deficiency of inhibitors, protein C (PC) in particular. Since a potential role of a new hemostatic factor named protein Z (PZ) has been reported in hypercoagulability, we evaluated plasma PZ and PC levels in thalassemia and their possible relation to the hypercoagulable state. Sixty subjects with thalassemia major and 10 with thalassemia intermedia (TI) followed at our Department were enrolled in the study. An age-matched control group of healthy subjects was considered. PZ, thrombin-antithrombin complexes, PC concentration (PC:Ag) and activity (PC:Act) were measured. PZ, PC:Ag and PC:Act were significantly lower in thalassemia major and thalassemia intermedia subjects than in 30 healthy controls (p < 0.001), while thrombin-antithrombin complex levels were significantly increased (p < 0.001) and related to PC levels but not to PZ levels (p < 0.05). PZ and PC levels are reduced in thalassemia but only PC has an effect on the thalassemia hypercoagulable state.

Abstract
BACKGROUND The MTHFR C677T genotype has been associated with increased risk of migraine, particularly of migraine with aura (MA) in selected clinical samples and with elevated homocysteine. The hyper-homocysteinemia may favor the vascular and neuronal mechanism underlying migraine, and the risk of stroke. OBJECTIVE The first aim of the present study was to examine the Contingent Negative Variation (CNV) amplitude and habituation pattern in a migraine sample versus non-migraine subjects, at the light of the MTHFR genotype, according to an unrelated and clinical based case-control panel. The second aim was to compare the frequency of Magnetic Resonance Imaging (MRI) subclinical brain lesions across the different C677 genotypes in the same migraine sample, selected for the young age and the absence of any cardiovascular risk factor. METHODS One hundred and five 18-45 year old out-patients, 90 affected by migraine without aura (MO) and 15 by MA, and 97 non-migraine healthy subjects, age and sex matched, were selected for the genetic analysis. All subjects had a common ethnic origin from Puglia. Sixty-four migraine subjects and 33 control subjects were submitted to the recording of the CNV. All migraine subjects underwent the MRI evaluation. RESULTS The frequency of homozygosis was 14.33% in normal subjects, versus 25.7% in MA + MO group (chi2-test: 10.80 P= .001). The frequency of homozygosis in MO patients, was 25.5% (MA versus N: chi2-test: 9 P= .003), in MA group it was 26.6%. Considering the MTHFR genotype in migraine patients and controls, the C677TT subjects exhibited a reduced habituation index of the early CNV (iCNV), in respect with both C677TC and C677CC; in the migraine group, there was a significant decrease of CNV habituation in patients with homozygosis and a positive correlation between the habituation index values and the homocysteine levels. Nineteen migraine patients exhibited subclinical brain lesions (18.05%): patients with C677T homozygosis did not exhibit a higher risk for MRI abnormalities. CONCLUSIONS This unrelated and clinical based case-control study showed that genetically induced hyper-homocysteinemia may favor the neuronal factors predisposing to migraine, while it does not influence the presence of subclinical vascular brain lesions probably linked with increased risk of stroke.

Abstract
PURPOSE Cardiomyopathy is one of the major complications of b thalassaemia major as a result of transfusional iron overload. The aim of our study is to evaluate with MR if there is any difference of iron deposition signal intensity (SI) or distribution between non-cardiopathic and cardiopathic thalassaemic patients in order to establish if there is a relationship between cardiopathy and iron deposition. MATERIALS AND METHODS We studied 20 patients affected by b thalassaemia major, of whom 10 cardiopathic and 10 non-cardiopathic, and 10 healthy volunteers as control group. Serum ferritin and left ventricular ejection fraction were calculated in thalassaemic patients. All patients were examined using a 1.5 MR unit with ECG-gated GE cine-MR T2*-weighted, SE T1-weighted and GE T2*-weighted sequences. In all cases, using an adequate ROI, the myocardial and skeletal muscle signal intensity (SI), the myocardial/skeletal muscle signal intensity ratio (SIR) and the SI average of the myocardium and skeletal muscle were calculated for every study group. The qualitative evaluation of iron deposition distribution was independently performed by three radiologists who analyzed the extension, the site and the morphology of iron deposition on the MR images and reported their observations on the basis of a four-level rating scale: 0 (absent), 1 (limited), 2 (partial), 3 (widespread deposition). The result of quantitative and qualitative evaluations were analysed with statistical tests. RESULTS Cardiac iron deposition was found in 8/10 non-cardiopathic thalassaemic patients and in all cardiopathic thalassaemic patients. We noticed a significant SI difference (p>0.05) between the healthy volunteer control group and the thalassaemic patients with iron deposition, but no significant SI difference in iron deposition between non-cardiopathic and cardiopathic thalassaemic patients in the areas evaluated. The qualitative evaluation revealed a different distribution of iron deposition between the two thalassaemic groups, with more widespread distribution in cardiopathic patients. CONCLUSIONS We found cardiac iron deposition also in non-cardiopathic b thalassaemic patients and a qualitative difference in cardiac iron distribution between non-cardiopathic and cardiopathic patients. The qualitative evaluation of cardiac iron deposition was useful for an easier classification of the disease, bypassing the SI quantitative value which is affected by the extremely uneven distribution of iron deposition and by the sampling technique used. MR evaluation of non-cardiopathic thalassaemic patients may be useful to evaluate early iron deposition and to establish the most suitable chelation therapy.

Abstract
AIM: Gallbladder and gastrointestinal motility defects exist in gallstones patients and to a lesser extent in pigment gallstone patients. To investigated the role of gallbladder and gastrointestinal motility disorders in pigment gallstone formation in β -thalassemia major.
METHODS: Twenty-three patients with β -thalassemia major (16 females; age range 18-37 years) and 70 controls (47 females, age range 18-40 years) were studied for gallbladder and gastric emptying (functional ultrasonography), orocecal transit (OCTT, H2-breath test), autonomic dysfunction (sweat-spot, cardiorespiratory reflex tests), bowel habits, gastrointestinal symptoms and quality of life (all with questionnaires). Gallbladder content (ultrasonography) was examined before and during 8-12 mo follow-up.
RESULTS: Gallstones and/or biliary sludge were found in 13 (56%) patients. β -thalassemia major patients had increased fasting (38.0 ± 4.8 mL vs 20.3 ± 0.7 mL, P = 0.0001) and residual (7.9 ± 1.3 mL vs 5.1 ± 0.3 mL, P = 0.002) volume and slightly slower emptying (24.9 ± 1.7 min vs 20.1 ± 0.7 min, P = 0.04) of the gallbladder, together with longer OCTT (132.2 ± 7.8 min vs 99.7 ± 2.3 min, P = 0.00003) than controls. No differences in gastric emptying and bowel habits were found. Also, patients had higher dyspepsia (score: 6.7 ± 1.2 vs 4.9 ± 0.2, P = 0.027), greater appetite (P = 0.000004) and lower health perception (P = 0.00002) than controls. Autonomic dysfunction was diagnosed in 52% of patients (positive tests: 76.2% and 66.7% for parasympathetic and sympathetic involvement, respectively). Patients developing sludge during follow-up (38%, 2 with prior stones) had increased fasting and residual gallbladder volume.
CONCLUSION: Adult β -thalassemia major patients have gallbladder dysmotility associated with delayed small intestinal transit and autonomic dysfunction. These abnormalities apparently contribute together with haemolytic hyperbilirubinemia to the pathogenesis of pigment gallstones/ sludge in β -thalassemia major.

Abstract
Hereditary hemochromatosis (HH) is an autosomal recessive trait regarding iron metabolism frequently found in Caucasian populations. The C282Y mutation of the HFE gene, held responsible for HH, has been identified as the major genetic basis for the phenotypic expression of HH whereas two additional mutations of the HFE H63D and S65C gene appear to be associated with a milder form of HH. A high allele frequency of C282Y and H63D has been reported in Northern European populations. In Italy, the overall allele frequency was 0.5% for the C282Y mutation, 12.6% for the H63D mutation and 1.1% for the S65C mutation. In this study, we evaluated the allele frequency of the three principal HFE mutations (C282Y, H63D, S65C) together with eight additional mutations (V53M, H63H, Q127H, E168Q, E168stop, W169stop, V59M, Q238P) in 500 healthy Apulian subjects. No subject homozygous for the C282Y mutation was found while 3% of subjects were heterozygous for this mutation. Heterozygosity and homozygosity for the H63D mutation were 26 and 1%, respectively. Only five subjects were heterozygous for the S65C mutation. Overall, the allele frequency was 1.5% for C282Y, 14% for H63D, 0.5% for S65C and 0% for the other mutations. The transferrin saturation (TS) was significantly higher in subjects heterozygous for the H63D mutations with respect to subjects with a normal genotype, though all were within the normal range. No statistically significant difference in the allele frequency was noted in the Apulian population compared to that in Northern and Southern Italy.

Abstract
During chorionic villi sampling for prenatal diagnosis with molecular biology techniques, contamination by maternal decidua frequently occurs and can lead to misinterpretation of the test results. To avoid such problems, we present a new method for appraising maternal contamination of fetal DNA, based on genomic typing of the highly variable human leukocyte antigen (HLA) locus-DRB1*, locus A* and locus B* regions by genetic amplification with sequence-specific primers and PCR. Fetal DNA samples obtained for beta-thalassemia diagnosis were analysed after artificial contamination with increasing maternal DNA concentrations ranging from 0.5 to 10% (0.5, 1, 3, 5 and 10%). The approach was found to be rapid, specific, reproducible and highly sensitive and permits recognition of 1-3% contamination by maternal DNA concentrations. The system currently used for detecting maternal DNA contamination in fetal samples is the analysis of polymorphic loci by variable number of tandem repeats and/or short tandem repeats. We propose that the analysis of HLA alleles may provide a valid alternative or complement to this system.

Abstract
BACKGROUND AND OBJECTIVES Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common erythrocytic enzymatic disorder in Italy and is characterized by wide clinical, biochemical and molecular variability. We studied the clinical and hematologic data from 54 G6PD-deficient, unrelated males from the Apulia region. DESIGN AND METHODS Analyses for enzymatic activity, G6PD electrophoresis and molecular typing were performed on all subjects. Thirty-nine subjects (72.2%) showed a severe G6PD deficiency (<10% residual enzymatic activity) and 15 subjects (27.8%) a moderate deficiency (10--60% residual activity). RESULTS The Mediterranean variant was found in 48.2% of cases, the Seattle variant in 33.3%, the A- variant in 7.45% and the Montalbano variant in 3.7%; the variant was not identified in four subjects. Thirty-two patients (59.2%) were asymptomatic; of these, 37.04% demonstrated acute hemolytic crises induced mainly by ingestion of fava beans and 3.7% had had neonatal jaundice. Acute hemolytic anemia was found in 53.8% of subjects with the Mediterranean variant, in 5.5% with the Seattle variant, in 100% with the A-variant and 0% with the Montalbano variant. INTERPRETATION AND CONCLUSIONS Enzymatic activity was shown to be a poor predictive parameter of acute hemolytic crises and was not correlated with clinical features. Subjects with Mediterranean or A- variants had a more severe clinical phenotype which was not related to enzymatic activity. The Seattle, and probably the Montalbano, variant appears to have a milder clinical expression.

Abstract
The kinetics of circulating lymphoid cells were evaluated in three children suffering from beta-thalassemia major after HLA-identical sibling placental blood transplant (PBT) in one patient and placental blood plus bone marrow transplantation (BMT) in two patients. Recovery of the main lymphocyte subsets, as determined by phenotype analysis of circulating PBMCs, was complete within 2 months after transplant. NK (CD56+) cells were the first to appear in peripheral blood, followed by T (CD3+, CD2+, CD7+) and B (CD19+) cells. Of the T lymphocytes, the CD8+ were the first to reconstitute, but recovery of CD4+ cells was also rapid and within 6 months these T cells reached normal values. The expression of CD57 by NK or T cells was slightly delayed. The evaluation of RA and RO isoform expression of the CD45 molecule showed a prevalence of the CD45RA antigen with a ratio of 2-3:1. In the PBT only patient, T cells expressing the CD45RO antigen prevailed in the early post-transplant period. Severe or chronic GVHD was not observed. This experience demonstrates that reconstitution of lymphocyte subsets is successful in genetic hematological diseases after transplantation of HLA-identical placental blood or placental blood plus bone marrow from healthy or heterozygous siblings. Bone Marrow Transplantation (2000) 26, 743-747.

Abstract
Analysis of haemoglobin chain synthesis was performed in 15 Apulian patients with Hb H disease and in their patients and offspring. The Apulian carriers of Hb H disease show a marked imbalance of alpha and beta chain synthesis (0.39 +/- 0.1) with variable clinical and haematological manifestations. However, we are dealing with an intermediate form similar to that described in Italians from other regions. A significant difference was found between the mean alpha/beta ratio values (0.81 +/- 0.13) of parents and offspring of Hb H patients and those of the normal controls (1.05 +/- 0.09); however, extensive overlapping between these two groups exists. These results have led us to the conclusion that the forms of alpha-thalassaemia found in Apulia are similar to the alpha defects observed in Sicily; in both cases, in fact, haemoglobin chain synthesis was an unreliable test for discriminating between alpha-thalassaemia-1 trait and alpha-thalassaemia-2 trait.

Abstract
To evaluate the effective role of hepatitis viruses in thalassemic (Th) liver disease, we carried out a long-term study in 42 subjects with nontransfusion-dependent Th minor hospitalized for an episode of acute viral hepatitis. 10 patients had serologic evidence of hepatitis A, 23 of hepatitis B and 9 of hepatitis non-A, non-B. In the follow-up chronic hepatitis was detected histologically in 5/23 patients with hepatitis B and 5/9 with hepatitis non-A, non-B. All hepatitis A patients recovered completely. The prevalence in 7 out of 10 patients with chronic hepatitis of piecemeal necrosis and of inflammatory changes over hepatic siderosis and fibrosis evidenced a determinant role of chronic viral infection in the development of liver damage in these patients. Thus, heterozygous nontransfusion-dependent Th patients seem to have a high risk of developing a chronic inflammatory liver disease especially after an episode of non-A, non-B hepatitis. Therefore, in our geographical area, chronic hepatitis of viral origin should be taken into account, among other pathogenetic factors, in many cases of cryptogenic thalassemic liver disease.
