Abstract
OBJECTIVE Myo-inositol supplementation prevents gestational diabetes (GDM) in women at risk and reduces insulin resistance in women with GDM. No data are available about its effect on glucose variability. The aim of this study was to evaluate the effects of a supplementation of myo-inositol on glucose variability in women with GDM. PATIENTS AND METHODS Myo-inositol effect on glucose variability was studied in a pilot case-control study involving 12 consecutive pregnant women (median age 34 years, 25.0% insulin-treated) with GDM. Six women received myo-inositol 2 g plus 200 mg folic acid twice a day, the others received only folic acid. Information on side effects was collected. A continuous glucose monitoring system was wore before and at the beginning of the supplementation. Mean amplitude of glucose excursion (MAGE), standard deviation (SD) and variability coefficient were the indexes of glucose variability. RESULTS Myo-inositol lowered glucose levels in the first days after the treatment was started. However, pre-post supplementation overall mean glucose difference was similar between groups (-4.8 vs. 5.0 mg/dL for controls and treated, respectively; p = 0.79). Pre-post differences in SD (13.7 vs. 6.0; p < 0.001), MAGE (3.5 vs.-1.5; p < 0.001) and variability coefficient (0.14 vs. 0.02; p < 0.001) were improved in myo-inositol group. No side effects were recorded. CONCLUSIONS Myo-inositol is effective in reducing glucose variability in women with GDM. It could be a useful strategy for treating GDM.

Abstract
OBJECTIVES Port-a-cath catheterization is often required for those patients who need long-term therapies (malnutrition, neoplasm, renal failure, other severe diseases). The use of ports for a wide range of indications is not exempt from complications. Ultrasound-guided central venous catheterization (CVC) is a safe and fast technique for the introduction of the catheter inside a central vein. This retrospective study reports our experience with US-guided CVC in patient eligible for port-a-cath implantation. MATERIALS AND METHODS From January 2007 to March 2017, 108 CVC (out of 770 procedures), were positioned using an ultrasound guide, with the new "one-shoot technique" (group 1) and the classic Seldinger technique (group 2). RESULTS One-shoot techniques showed a reduced operative time, in comparison to Seldinger technique, with a negligible minor complication rate. No major complication were evidenced. CONCLUSIONS CVC is a safe procedure, although not free from complications. Ultrasonography enhances safety of the procedure by decreasing puncture attempts and complications; it is helpful in patients with vascular anatomical variations, with no visualized or palpable landmarks or for patients with coagulation disorders.

Abstract
OBJECTIVE This study aimed at evaluating the effects obtained by administering 30 mg of micronised dispersible ferric pyrophosphate plus 300 mg of alpha-lactalbumin (MDFP-AL) compared to 80 mg of ferrous gluconate (FG) in pregnant women affected by iron-deficiency anemia (IDA). PATIENTS AND METHODS We considered eligible all second-trimester singleton pregnancies in women affected by IDA. We excluded any other disease, twin pregnancies, any other pharmacologic/nutraceutical treatments (besides folic acid) before/during pregnancy. We randomized patients in two groups: one underwent treatment with 1 tablet of MDFP-AL/day, the other one with 1 tablet of FG/day, for 30 days. We evaluated hemoglobin (Hb), ferritin, red blood cells (RBCs), serum iron, hematocrit (Hct), and side effects at baseline (T0), after 15 days (T1) and 30 days (T2). RESULTS 50 women met the inclusion/exclusion criteria. We did not observe significant differences between the two groups for mean age, gestational age at the enrollment and parity. In MDFP-AL group, after 15 days (T1) Hb, ferritin, serum iron and Hct and were significantly improved respect to baseline (T0); after 30 days (T2), all the parameters, including RBCs, were significantly improved respect to baseline (T0). Similarly, in FG group the investigated parameters were improved both after 15 (T1) and 30 days (T2) respect to baseline (T0), although less in percentage terms respect to MDFP-AL group. The side effects rate was 24% in FG group, whereas MDFP-AL group did not show any significant side effect. CONCLUSIONS Overall, MDFP-AL is more effective and safe than FG for the treatment of IDA in pregnant women.

Abstract
PURPOSE Urinary tract infection (UTI) is defined as a common bacterial infection that can lead to significant morbidity such as stricture, fistula, abscess formation, bacteremia, sepsis, pyelonephritis, and kidney dysfunction with a mortality rates reported of 1% in men and 3% in women because of development of pyelonephritis. UTIs are more common in women and the 33% of them require antimicrobials treatment for at least one episode by the age of 24 years. UTIs are the most common infections observed during pregnancy and up to 30% of mothers with not treated asymptomatic bacteriuria may develop acute pyelonephritis which consequently can be associated to adverse maternal and fetal outcomes. All bacteriuria in pregnancy should be treated with antimicrobial treatments being safe for both the mother and the fetus. Approximately one every four women receives prescription of antibiotic treatment during pregnancy, nearly 80% of all the prescription medications during gestation. The use of fosfomycin to treat cystitis in pregnancy generally considered safe and effective. Even though use on antibiotics for urinary tract infections is considered generally safe for the fetus and mothers, this opinion is not based on specific studies monitoring the relationship of among urinary infections, consumption of antibiotics, and pregnancy outcomes. MATERIALS AND METHODS On this basis we decided to analyze data from the database of our multicenter study PHYTOVIGGEST, reporting data from 5362 pregnancies, focusing on use of fosfomycin. Principal outcomes of pregnancy in women treated with fosfomycin were taken into consideration. RESULTS Women who have been treated with urinary antibiotics during the pregnancy were 183. With respect to the total number of pregnancies of our sample, these women represented the percentage of 3.49% (187/5362). Analysis of different outcomes of pregnancy such as gestational age, neonatal weight, and neonatal Apgar index did not show any significant difference. At the same time, analysis of data of pregnancy complicancies (such as urgent cesarean delivery, use of general anesthesia, need to induce labor) did not show any difference in women taking fosfomycin during pregnancy and those not taking it. CONCLUSIONS Our data, based on a large number of pregnancies, confirm the safety use of fosfomycin use in pregnancy.

Abstract
OBJECTIVE Vitamin D is a fat-soluble secosteroid hormone that regulates calcium, magnesium, and phosphate homeostasis and plays a pivotal role as antiproliferative and immunomodulatory mediator. Considering the different sources of synthesis and dietary intake as well as the pleiotropic actions in extremely diverse (micro)environments of the body, the supplementation of this Vitamin should be carefully evaluated taking into account the several pathways that it regulates. In the current brief review, we aimed to summarize the available evidence about the topic, in order to suggest the best evidence-based supplementation strategy for human reproduction, avoiding the unuseful (and sometimes hazardous) empiric supplementation. MATERIALS AND METHODS Narrative overview, synthesizing the findings of literature retrieved from searches of computerized databases. RESULTS Accumulating evidence from in vitro fertilization (IVF) trials suggests that fertilization rate decreases significantly with increasing levels of 25OH-D in follicular fluid; in addition, Vitamin D levels in the follicular fluid are negatively correlated to the quality of embryos and the higher values of Vitamin D are associated with lower possibility to achieve pregnancy. Both low and high Vitamin D serum concentrations decrease not only spermatozoa count, but their progressive motility as well as increase morphological abnormalities. Finally, studies in animal models found that severe hypervitaminosis D can reduce the total skeletal calcium store in embryos and may compromise the postnatal survival. CONCLUSIONS Based on the retrieved data, we solicit to be extremely selective in deciding for Vitamin D supplementation, since its excess may play a detrimental role in fertility.

Abstract
Gestational diabetes mellitus (GDM) is a condition of abnormal maternal glucose tolerance that occurs, or is detected, for the first time during pregnancy. The new diagnostic strategies recommend a 75 g, 2-h glucose tolerance test for all women not already known to be diabetic, in the early 3rd trimester of pregnancy. GDM is diagnosed when one or more values is equal to or exceeds the thresholds suggested (i.e. fasting ≥ 5.1 mmol/l, 1-h ≥ 10.0 mmol/l and 2-h ≥ 8.5 mmol/l). This criteria will determine a significant increase of the prevalence of GDM, primarily because only one abnormal value (OAV), not two, is sufficient to make the diagnosis. We also suppose that the new cases of gestational diabetes diagnosed with the new criteria will have an increased risk for subsequent abnormal glucose tolerance later in life, as it was largely confirmed in the past for the patients with two or more abnormal values.

Abstract
SUMMARY Postmenopausal estrogen decline is implicated in several age-related physical and psychological changes in women, including decreases in perceived quality of life. The phytoestrogen genistein at a dose of 54 mg daily in osteopenic postmenopausal women after 2 years implies an improvement on quality of life and depression symptoms. INTRODUCTION Postmenopausal estrogen decline is implicated in several age-related physical and psychological changes in women, including decreases in perceived quality of life (QoL). A number of trials with hormone therapy showed beneficial effects of the intervention on quality of life parameters. However, because of known or suspected serious side effects of conventional hormone therapy, there is a need for alternatives. METHODS We conducted a double-blind randomized placebo-controlled trial using the isoflavone genistein, 54 mg, or placebo for 2 years. In this trial, we recruited 262 postmenopausal women aged 49 to 67 years. RESULTS At baseline, after 1 year, and at final visit, participants filled in the Short Form of 36 questions (SF-36) and the Zung Self-rating Depression Scale (ZSDS). For the placebo group, scores on all dimensions of the SF-36 decreased after 1 and 2 years. The genistein group showed increases on all dimensions of the SF-36 at the end of the study. There were, however, statistically significant differences in changes of scores between the two intervention groups. For the ZSDS, similarly, significant differences were found between groups. CONCLUSION In conclusion, the findings of this randomized trial showed that genistein improves quality of life (health status, life satisfaction, and depression) in osteopenic postmenopausal women.

Abstract
There is a debate about whether universal or risk factors-based screening is most appropriate for gestational diabetes diagnosis. The aim of our retrospective study was to compare in our population the universal screening test recommended by the International Association of Diabetes in Pregnancy Study Group (IADPSG) panel and the American Diabetes Association (ADA) versus the selective screening proposed by the United Kingdom National Institute for Health and Clinical Excellence guidelines (NICE) but modified by the Italian National Institute of Health. From May 2010 to October 2011 all consecutive pregnant women were screened for gestational diabetes according to the IADPSG's panel criteria, while all the risk factors for each patient were registered. Of the 1015 pregnant women included in the study, 113 (11%) were diagnosed with gestational diabetes and 26 (23%) of them would not have been identified by the selective screening proposed by the Italian National Institute of Health. However, all the risk factors considered by the selective screening revealed a good predictive role except for maternal age ≥ 35 years (OR: 0.98). In the group without the risk factors considered, it was reported the predictive role for gestational diabetes of prepregnancy BMI and nulliparity. The selective risk factors-based screening proposed by the Italian National Institute of Health has detected 77% of gestational diabetes cases in our population, sparing the oral glucose tolerance test for more than 40% of pregnant women at the same time. More information on the clinical impact of this choice could be obtained by a strict analysis of treatment, perinatal outcome and follow-up of an adequate sample size of "missed" gestational diabetes.

Abstract
of this study were to assess diastolic function in pregnant women with abnormal glucose tolerance (AGT), compared with normal glucose tolerance (NGT) women, and to evaluate the insulin resistance status and its association with Doppler-echocardiographic indexes. Echocardiograms of 108 consecutive Caucasian women with singleton pregnancies were performed. Insulin resistance status was estimated by the homeostasis model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI). All the studied women showed normal diastolic patterns. Patients with AGT (50.9%), as compared with NGT women, had higher HOMA-IR (1.70 ± 1.30 versus 1.01 ± 0.81, P = 0.003), lower QUICKI (0.36 ± 0.005 versus 0.40 ± 0.06, P = 0.004), higher lateral mitral annulus late diastolic velocity (13.6 ± 4.9 versus 11.9 ± 4.9, P = 0.03), and higher A-wave velocity, the wave responsible for the active atrial contraction component (75.2 ± 14.2 versus 67.7 ± 16.2, P = 0.01). At multivariate regression analysis HOMA-IR was the only parameter associated with A-wave velocity. In conclusion, women with AGT had an increased subclinical diastolic active participation, which is associated with higher levels of insulin resistance. For the increased risk of deterioration of cardiac diastolic function, earlier and more seriously than normal pregnancy, AGT women may have a careful followup to detect the early signs of cardiac alteration and to prevent cardiovascular diseases.

Abstract
To evaluate retrospectively the prevalence of gestational diabetes (GD) in pregnancies obtained with myo-inositol administration in women with polycystic ovary syndrome. A total of 98 pregnancies in PCOS women obtained in a 3-year period, either with myo-inositol (n. 54), or with metformin (n. 44) were considered. While myo-inositol was assumed through the whole pregnancy, the group of women treated with metformin stopped the drug assumption after pregnancy diagnosis, and was considered as a control group. After having eliminated cases of miscarriages and twin pregnancies, a definitive number of 46 women in the myo-inositol group and 37 in the control group was taken in account to be retrospectively evaluated. The primary outcome measure was GD occurrence in both groups; whereas secondary outcome measures were pregnancy outcomes: hypertensive disorders, pre-term birth, macrosomia and caesarean section occurrence. Prevalence of GD in the myo-inositol group was 17.4% versus 54% in the control group, with a highly significant difference also after adjusting for covariates. Consequently, in the control group the risk of GD occurrence was more than double compared to the myo-inositol group, with an odds ratio 2.4 (confidence interval 95%, 1.3-4.4). There was no difference between the groups in relation to secondary outcome measures. This study suggests a possible effect of myo-inositol in the primary prevention of GD in PCOS women.

Abstract
AIM To evaluate the correspondence between first-trimester fasting glycaemia and the results of the OGTT in diagnosing gestational diabetes (GDM). METHODS The medical records of all consecutive women who had undergone a diagnostic OGTT, performed according to the IADPSG, during the past year were retrospectively reviewed. All first-trimester fasting glucose values greater or equal to 5.1 mmol/L (92 mg/dL), recommended as a diagnostic value, were also verified for each patient in this cohort. Moreover, a ROC curve and a multiple logistic-regression model were constructed to calculate the predictive capability of this cut-off value in diagnosing GDM. RESULTS In our population of 738 eligible pregnant women, an 11.9% prevalence of GDM was revealed by OGTT. However, when the first-trimester fasting glucose value for each patient was retrospectively considered, there were a further 29 patients who should have been diagnosed as GDM cases (glycaemia ≥ 5.1 mmol/L), although their OGTT was normal. Yet, when the value of fasting glucose was considered not diagnostic, but only predictive, an AUC of 0.614 (95% CI: 0.544-0.684) and an aOR of 7.1 (95% CI: 3.8-13.1) was obtained in these patients compared with the reference group (fasting glucose < 5.1 mmol/L). CONCLUSION There was no complete correspondence in diagnosing GDM between the first-trimester fasting glucose value and the results of a 2-h 75-g OGTT performed early in the third trimester. However, albeit not diagnostic, a fasting glucose value greater or equal to 5.1 mmol/L may be considered a highly predictive risk factor for GDM.

Abstract
OBJECTIVE To evaluate the 12-month effect of myo-inositol treatment on some biochemical parameters of women affected by metabolic syndrome. METHODS Eighty outpatient postmenopausal women, affected by metabolic syndrome, were enrolled in a 12-month study. All women were treated with a low-energy diet, and then they were randomly assigned to myo-inositol 2 g b.i.d. (n = 40) or placebo (n = 40). All the women were evaluated for serum glucose, insulin, HOMA-IR (Homeostasis Model Assessment-Insulin Resistance), triglycerides, total and high density lipoprotein cholesterol, body mass index (BMI), waist circumference and blood pressure at baseline and after 12 months of treatment. RESULTS With the exception of BMI and waist circumference, after 12 months of treatment, all the parameters studied showed a significant improvement in the myo-inositol group compared to the control group. At the end of the study, in the myo-inositol group, the number of women without metabolic syndrome was eight (20%) whereas, in the control group, only one woman no longer had the metabolic syndrome after 12 months of diet. CONCLUSIONS Myo-inositol might be considered one of the insulin-sensitizing substances in the treatment of metabolic syndrome.

Abstract
AIM To test the hypothesis that myoinositol supplementation will improve insulin sensitivity as measured by markers of insulin resistance such as homeostasis model assessment of insulin resistance and adiponectin in women with gestational diabetes. METHODS The trial was carried out in diet-treated patients with gestational diabetes diagnosed in our department between April 2008 and September 2009. Subjects were randomly assigned to receive either myoinositol supplementation (4 g daily) plus folic acid (400 μg daily)-the study group-or folic acid only (400 μg daily)-the control group. Both groups received the same diet prescription. Homeostasis model assessment of insulin resistance and adiponectin were assayed while fasting at the time of the diagnostic oral glucose tolerance test and after 8 weeks of treatment. RESULTS There were 69 evaluable patients, 24 in the study group and 45 in the control group. Fasting glucose and insulin, and consequently homeostasis model assessment of insulin resistance, decreased in both groups (50% in the study group vs. 29% in the control group), but the decline in the study group was significantly greater than that in the control group (P = 0.0001). Adiponectin increased in the myoinositol group while it decreased in the control group (P = 0.009). CONCLUSION Myoinositol improves insulin resistance in patients with gestational diabetes.

Abstract
Osteoporosis is characterized by reduced bone mass and structural deterioration of bone tissue leading to enhanced bone fragility and a consequent increase in fracture risk. Bone loss further increases in postmenopausal women when the ovaries stop making estrogens. Women undergoing treatment for osteoporosis require long-term dosing therapeutic regimens, that offer no symptomatic relief, and may cause side effects. To avoid this problem, many therapeutic alternatives have been proposed. Epidemiological data support a robust relationship between soy isoflavones, fracture incidence and bone mineral density in osteoporotic, postmenopausal women. These suggest that a high isoflavone intake, restores the metabolic balance of bone formation and resorption. However, this matter is still controversial and several reports show negative results, probably because different doses and/or isoflavones have been used. Although it is difficult to identify the specific isoflavone most involved in preventing or restoring bone loss, a review of current literature based on new encouraging preclinical and clinical data, indicates that aglycone genistein appears to be the most effective isoflavone in preserving bone health. Genistein aglycone, through a peculiar anti-osteoporotic dual mode of action, can positively regulate bone cell metabolism rebalancing bone turnover towards bone formation. Genistein in fact stimulates osteoblast and inhibits osteoclast function, mainly through the osteoprotegerin-sRANKL system. The positive results achieved by genistein aglycone intake, in terms of efficacy and safety, have stimulated the development of specially formulated medical food products for the clinical management of postmenopausal bone loss.

Abstract
INTRODUCTION obesity (O) is a chronic patologic condition, evolutive and relapsing, with multifactorial etiopathogenesis, consisting in an alteration of the body's composition characterized by a relative and absolute excess of fat, that gets worse the life quality and causes complications that can lead to death. PATIENTS AND METHODS experience concerns twenty-five diabetic obese patients underwent bilio-intestinal by-pass between January 2006-December 2007. All these patients, before the surgical operation, underwent a rigorous clinical and laboratory examination. Besides, a precise rate control of laboratory, overlap with those performed in the pre-operative period of operation, was required for each patient: the first after one month, the second after six months and the third after twelve months. RESULTS the average weight loss was about 40 kg and, more important, these data show that the BMI is reduced, until to become stable, after 12 months from surgical operation, about values 34-31 Kg/m², obtaining, in this way, an improvement of values in the development metabolic syndrome and, above all, heart rate and ventricular repolarization. CONCLUSIONS the data obtained by our study support the hypothesis to suggest the operations of bariatric malassorbing surgery, in particular bilio-intestinal by-pass, as prophylactic methods for dismetabolics diseases, with reduction of cardiovascular risk in obese patient.

Abstract
BACKGROUND AND AIM Recent evidence suggests that genistein aglycone may act beneficially on surrogate cardiovascular risk markers in postmenopausal women. We assessed the effects of genistein aglycone on some cardiovascular risk factors and homocysteine levels after 3-years of continued therapy in a cohort of osteopenic, postmenopausal women. METHODS AND RESULTS The parent study was a randomized, double-blind, placebo-controlled trial involving 389 postmenopausal women with low bone mass for 24 months. Subsequently, a subcohort (138 patients) continued therapy for an additional year. Participants received 54mg of genistein aglycone (n=71) or placebo (n=67), daily. Both arms received calcium and vitamin D(3) in therapeutic doses. Moreover, 4 weeks before randomization procedures and during our follow-up study, all patients received dietary instructions in an isocaloric fat-restricted diet. Blood lipid profiles, fasting glucose and insulin, insulin resistance (HOMA-IR), fibrinogen, osteoprotegerin (OPG) and homocysteine at baseline and after 24 and 36 months of treatment were measured. Compared to placebo, genistein significantly decreased fasting glucose and insulin, HOMA-IR, fibrinogen and homocysteine after 24 and 36 months of treatment. By contrast, isoflavone administration did not affect high-density lipoprotein cholesterol and triglycerides though serum OPG was higher in the genistein recipients. There were no differences in adverse events or discomfort between groups. Results on routine biochemical, liver function, and hematologic testing did not change over time in placebo or genistein group. CONCLUSIONS After 3-years of treatment, genistein aglycone plus calcium, vitamin D(3) and a healthy diet showed positive effects on some cardiovascular risk factors and homocysteine levels in a cohort of postmenopausal women with low bone mass.

Abstract
AIMS Neutrophil gelatinase-associated lipocalin (NGAL) is highly expressed in damaged epithelia, during inflammation and cardiovascular disease. Soluble NGAL was measured in women who subsequently developed gestational diabetes. METHODS From a cohort of 908 pregnant outpatients who participated in a screening programme for Down's syndrome at 9-12 weeks of gestation, we considered all 41 women with a singleton pregnancy, who developed gestational diabetes in the previous 12 months, and a control group of 82 normal pregnancies. Circulating NGAL and insulin resistance by homeostasis model assessment ratio (HOMA-IR) were determined in the first trimester. RESULTS Median serum NGAL concentrations were higher in the gestational diabetes group [51.3 ng/ml (39.8-66.1 ng/ml)] compared with the control group [17.8 ng/ml (15.5-20.9 ng/ml)] (P < 0.001) and positively correlated with HOMA-IR (P < 0.001). CONCLUSIONS In the first trimester, circulating NGAL was significantly increased in women who subsequently developed gestational diabetes compared with the control group.

Abstract
UNLABELLED This study aimed at evaluating the effects of genistein (54 mg/die) on calcaneus and phalanges ultrasound (QUS) parameters and bone mineral density in osteopenic postmenopausal women. We concluded that genistein prevented bone loss in the osteopenic postmenopausal women and improves QUS parameters at the calcaneus and phalanges. INTRODUCTION The purpose of the study was to evaluate the effects of genistein (54 mg/die) on quantitative ultrasound (QUS) parameters of the calcaneus and hand phalange and on bone mineral density (BMD) in osteopenic postmenopausal women. METHODS One hundred thirty-eight women (age 49-67 years) were assigned to receive genistein or placebo. Bone status was assessed by measuring the anteroposterior lumbar spine and femoral neck BMD by dual energy X-ray absorptiometry and by ultrasound of the calcaneus (Achilles Plus, GE, Lunar) and of the phalanges (Bone Profiler. IGEA) at baseline and after a 1- and 2-year treatment. RESULTS At the end of the experimental period, genistein had significantly increased BMD in the femur and lumbar spine (p < 0.001). The stiffness index, amplitude-dependent speed of sound, and bone transmission time in the genistein group had increased significantly at the end of study (+5.3, p < 0.001; +3.6%, p < 0.001; +4.6, p < 0.001, respectively). CONCLUSIONS This study confirms that genistein prevented bone loss in the osteopenic postmenopausal women and it improves the QUS parameters.

Abstract
OBJECTIVE To evaluate the importance of adiponectin and insulin resistance in early- and late-onset pre-eclampsia. DESIGN A nested case-control study in 72 pregnant women who participated in the first-trimester Down-syndrome-screening programme and who delivered at our hospital. SETTING University Hospital, Department of Obstetrics and Gynecology. POPULATION Pregnant women: 36 women with pre-eclampsia of which 20 late onset and 16 early onset were compared with 36 uncomplicated pregnancies who delivered at term. METHODS In all the women, insulin resistance was calculated by the homeostasis model assessment ratio (HOMA-IR) and plasma adiponectin was determined using an enzyme-linked immunosorbent assay. MAIN OUTCOME MEASURES Insulin resistance and adiponectin concentration. RESULTS First-trimester plasma adiponectin mean levels in the whole pre-eclampsia group were significantly lower than that in the control group (8.4 +/- 3.3 versus 14.8 +/- 4.6 microgram/ml; P < 0.001), whereas first-trimester mean HOMA-IR values were significantly higher in the pre-eclampsia group than that in the control group (2.0 +/- 1.1 versus 1.0 +/- 0.4; P= 0.01). Plasma adiponectin concentrations at delivery in the pre-eclampsia group were significantly higher than that in the control group (9.2 +/- 3.7 versus 7.8 +/- 2.6 microgram/ml; P= 0.04). First-trimester plasma adiponectin mean concentrations in the late-onset subgroup were significantly lower compared with the concentrations in early-onset subgroup (6.2 +/- 1.4 microgram/ml versus 11.1 +/- 3.2 microgram/ml; P < 0.001), and there was a significant difference in adiponectin plasma values only between women in the late-onset pre-eclampsia group versus those in the control group (P < 0.001). First-trimester mean HOMA-IR values were significantly higher in the late-onset subgroup compared with that of the early-onset subgroup (2.5 +/- 1.3 versus 1.3 +/- 0.3; P= 0.02), and there was a significant difference only between the control group versus the late-onset subgroup (P= 0.001). CONCLUSIONS First-trimester adiponectin and HOMA-IR values seem to select two completely different populations: early- and late-onset pre-eclampsia, which might suggest a different pathogenesis.

Abstract
OBJECTIVE To verify the compliance with hormone replacement therapy (HRT) over 2 years in a population of postmenopausal women in East Sicily. STUDY DESIGN Patients starting hormonal therapy for the first time were enrolled in this study. A telephone survey was then conducted after 3, 6, 12 and 24 months and the reasons for any discontinuation were recorded. RESULTS Of a total of 138 women who agreed to be enrolled in this prospective longitudinal study 72 were still taking the treatment after 1 year and only 56 at the end of the study, although only three patients reported that they had experienced no benefit. CONCLUSIONS Type of work, surgical menopause and previous use of oral contraceptives were significantly statistically associated with better HRT compliance. Side effects and fear of breast cancer, which we maintain is exaggerated by the women and their family doctors, were the commonest reasons for early discontinuation of the hormonal treatment.

Abstract
Gestational diabetes mellitus (GDM) is a risk factor for both Type 2 diabetes (DM2) and insulin-resistance syndrome (IRS). C-reactive protein (CRP), fibrinogen and leukocyte count are increased in the IRS and predict DM2 and cardiovascular disease (CVD). The chemochine monocyte chemoattractant protein-1 (MCP-1/CCL2) is also elevated in DM2 and CVD. Recent evidence suggests a relation between chronic inflammation and GDM, but post-delivery information on inflammatory markers in these high-risk women is lacking. Serum levels of CRP, fibrinogen, MCP-1/ CCL2, and leukocyte blood count have been assessed in 26 women with and 26 women without a recent history of GDM, matched for age, body mass index (BMI), post-partum duration and parity. DM2 was excluded in all the participants by an oral glucose tolerance test (OGTT). Women with previous GDM showed significantly higher CRP (p=0.007) and fibrinogen (p=0.02) serum concentrations, whereas MCP-1/CCL2 serum levels and leukocyte blood count were comparable in the two groups. Overall, CRP levels significantly correlated with BMI (r=0.40, p=0.03), waist-to-hip ratio (WHR) (r=0.44, p=0.001), fasting insulin (r=0.27, p=0.04), insulin-resistance assessed by means of the homeostatic model (HOMA) (r=0.28, p=0.04), and fibrinogen concentration (r=0.49, p=0.0001). At linear regression analysis, only WHR and fibrinogen were independently associated with CRP levels. In conclusion, the increase of inflammatory markers may be one of the first detectable disorders in healthy women at high risk of DM2 and IRS, like those with a GDM history.

BACKGROUND Human papillomavirus type 16 (HPV16) is strongly implicated in the etiology of cervical cancer, with the expression of HPV16-encoded E7 oncoprotein in infected epithelial cells contributing to their malignant transformation. Although nuclear E7 interacts with several nuclear targets, we have previously shown that extracellular E7 can cause suppression of immune cell function. Moreover, cervical microvascular endothelial (CrMVEn) cells treated with E7 increase their expression of adhesion molecules. High levels of some cytokines in serum and in cervicovaginal secretions are associated with the progression of cervical cancer. In this study, we investigated the effects of extracellular E7 on cytokine production and on cytoskeleton structure of CrMVEn cells and vascular endothelial cells from different organs. METHODS Immunocytochemical staining and flow cytometry techniques were used to detect E7 in endothelial cells incubated with purified E7 protein. Laser scanning confocal microscopy was used to study the E7-induced modification of the endothelial cytoskeleton. An enzyme-linked immunosorbent assay was performed to measure the production of two cytokines, interleukin 6 (IL-6) and interleukin 8 (IL-8), by E7-treated endothelial cells. All statistical tests were two-sided. RESULTS Extracellular E7 was taken up by CrMVEn cells and localized to the cytoplasm. CrMVEn cells showed a statistically significant (P<.02) increase in the production of IL-6 and IL-8 after treatment with E7 compared with the controls. CrMVEn cells also produced higher levels of these cytokines than did the other endothelial cells (P<.01). E7 also induced marked alterations in the endothelial cytoskeleton of CrMVEn cells as a result of actin fiber polymerization. CONCLUSION These findings suggest a novel mechanism by which E7, as an extracellular factor, can play a role in the progression and dissemination of cervical cancer via its selective effects on endothelial cells.

Abstract
BACKGROUND In healthy primiparas the total body water content increases by about 8 liters within the last trimester, with a consequent reduction in plasma arginine-vasopressin (AVP) levels. The aim of the present study was to investigate the effect of normal pregnancy on urinary excretion of AQP2, a vasopressin sensitive water channel. METHODS Forty-five healthy pregnant primiparas (specify mean age and range) with a physiological single-fetus pregnancy were studied during weeks 12, 24 and 36 of pregnancy and then for 3 to 5 days postpartum. The control group consisted of 14 age-matched women in the early follicular phase of the menstrual cycle (day 5 or 6). The behavior of plasma AVP, ANP, oxytocin, urinary 6-keto-PGF1alpha (a metabolite of prostacyclin) and urinary AQP-2 excretion were evaluated in all subjects. RESULTS Plasma ANP and oxytocin, and urinary AQP-2 and 6kPGF1alpha excretion increased during all three trimesters, with the highest peaks at the 36(th) week. In the postpartum period, these values markedly decreased. No statistically significant changes were found in plasma AVP levels throughout the study period. CONCLUSIONS Our findings suggest that a non-AVP factor present in pregnancy plays a role in the control of the excretion of AQP-2 water channels.

Abstract
OBJECT To determine whether length of pre-operative treatment with gonadotrophin-releasing hormone agonists (GnRHa) may have different effects on uterine shrinkage and intra-operative blood loss, 36 patients with symptomatic uterine fibroids awaiting myomectomy were randomly divided into two groups. METHOD Twenty patients received long-term GnRHa administration, six monthly depot injections of leuprolide acetate (LA), while 16 patients were treated with two monthly LA injections before surgery. The hemoglobin concentration and estradiol, follicle-stimulating hormone and luteinizing hormone concentrations were measured before and after treatment in both groups. RESULTS Uterine volume decreased in the long-term treated group from 680+/-276 cm3 to 486+/-195 cm3 (36%) after two and to 388+/-172 cm3 (51%) after six LA injections. In the short-term treated group the basal uterine volume decreased from 745+/-320 cm3 to 456+/-177 cm3 (39%) after two LA injections. The uterine volume decrease was statistically significant (p<0.05) after two LA injections in both groups while the decrease observed between two and six LA injections was not significant (p>0.05). The intra-operative blood-loss was not significantly different between the two groups studied, 315+/-93 cm3 and 336+/-88 cm3. CONCLUSION Two pre-operative GnRHa depot injections offer similar results, in terms of uterine shrinkage and intra-operative blood loss, and a longer treatment seems to be justified in cases of anemia.

Abstract
The endothelium is thought to play an important role in the genesis of atherosclerosis, and several lines of evidence suggest that the effect of an intervention on endothelial function might predict its involvement in coronary disease progression and in the rate of cardiovascular events. Estrogen has direct effects on the blood vessel wall, indicating that vascular endothelium may play a key role in the cardiovascular protective effects of hormone replacement therapy (HRT). Raloxifene relaxes coronary arteries in vitro by an estrogen receptor-dependent and NO-dependent mechanism, thus suggesting that this selective estrogen receptor modulator could also have beneficial effects on endothelial function. This study compared the effects of HRT and raloxifene on NO products, endothelin-1 plasma levels, and endothelium-dependent vasodilatation in postmenopausal women. Healthy postmenopausal women (n=90) were enrolled in a double-blind, randomized, placebo-controlled, 6-month trial. Women were randomly assigned to receive continuous HRT (1 mg 17beta-estradiol combined with 0.5 mg norethisterone acetate), raloxifene (60 mg/d), or placebo for 6 months. Flow-mediated endothelium-dependent vasodilation of the brachial artery, plasma NO concentrations, and endothelin levels were measured at baseline and after 6 months of therapy. The mean baseline level of NO breakdown products was 26.5+/-10.7 micromol/L and increased to 36.3+/-11.4 micromol/L after 6 months of treatment with raloxifene. The mean baseline plasma endothelin level was 17.3+/-8.9 pg/mL and decreased to 11.5+/-2.1 pg/mL after 6 months of treatment with the selective estrogen receptor modulator. The mean baseline ratio of NO (breakdown products) to endothelin was also significantly increased at the end of treatment with raloxifene. Postmenopausal women treated with HRT had similar changes in plasma nitrites/nitrates and endothelin levels as well as in the ratio of NO to endothelin. In contrast, these markers of endothelial function did not change in the placebo-treated women. Flow-mediated endothelium-dependent vasodilation of the brachial artery was 8.3+/-2.1% at baseline and increased to 12.3+/-2.1% after 6 months of treatment with raloxifene. HRT also caused a significant and similar increase in flow-mediated endothelium-dependent vasodilation. No change in flow-mediated vasodilation was observed in the participants treated with placebo. We conclude that raloxifene therapy and HRT influence endothelial function and improve flow-mediated endothelium-dependent vasodilation to a comparable extent in healthy postmenopausal women at least after a 6-month treatment period. However, further investigation is warranted to enhance our understanding of the mechanisms of the effect of raloxifene on vascular function and to determine whether its effect on endothelial function may contribute to the reduction in cardiovascular-related morbidity and mortality.

Abstract
Raloxifene hydrochloride binds to the estrogen receptor and shows tissue-selective effects; thus, it belongs to a class of drugs recently described as selective estrogen receptor modulators (SERMs). Tissue selectivity of raloxifene may be achieved through several mechanisms: the ligand structure, interaction of the ligand with different receptor subtypes in various tissues, and intracellular events after ligand binding. Raloxifene has estrogen-agonist effects on bone and lipids and estrogen antagonist effects on the breast and uterus. In addition to its well established effects on osteoporosis, recent preclinical and clinical findings suggest that raloxifene also possesses beneficial effects on the cardiovascular system. These findings indicated that raloxifene may have cardioprotective properties without an increased risk of cancer or other side effects. Raloxifene has been shown to reduce total and low-density lipoprotein cholesterol concentrations in plasma, an effect similar to that produced by estrogens. Unlike estrogens, however, raloxifene does not increase high-density lipoprotein cholesterol and triglyceride levels in plasma. Endothelium is thought to play an important role in the genesis of atherosclerosis. Several lines of evidence suggest that an intervention with endothelial function might influence the progression of coronary disease and the incidence of cardiovascular events. Raloxifene increases the nitric oxide/endothelin-1 ratio, and improves endothelium-dependent vasomotion in post-menopausal women to the same extent as estrogens. Furthermore, in two randomized trials on post-menopausal women raloxifene reduced homocysteine levels, another independent risk factor for the development of cardiovascular disease. Although estrogens remain the drugs of choice in the hormonal therapy of most postmenopausal women, raloxifene may represent and alternative in women who are at risk of coronary artery disease.

Abstract
The forensic application of mtDNA typing requires large databases which are regionally well defined. To further this aim, we have typed mtDNA in a sample of 111 French and 106 Sicilians. The French were typed for both hypervariable segments (HVR1 and HVR2) of the mtDNA control region, whereas the Sicilians were only typed for HVR1, but in addition for the coding region RFLP markers for mtDNA groups H, I, J, K, L, M, T, U, V and X. In both samples, the predominant sequence type by far was the Cambridge reference sequence. Comparing HVR1 sequences, we found that the French sample was twice as diverse as the Sicilian sample as measured by sequence matches. A further set of sequence match comparisons including the French, Sicilian, and the published British mtDNA samples, demonstrate that sequence matching probabilities within samples differ by less than a factor of 2 from the matching probabilities between samples.

Abstract
OBJECTIVES E7 is one of the oncoproteins encoded by human papillomavirus-16 (HPV-16), the major etiologic factor responsible for cervical cancer. Human papillomavirus-16-E7 expressed by human uterine cervix carcinoma cells is also released in the extracellular compartment where it induces immune suppression. We investigated whether E7 was also responsible for the enhanced endothelial adhesiveness required in cancer progression. STUDY DESIGN/METHODS We treated cervical microvascular endothelial cells (CrMVEn) and human umbilical vein endothelial cells (HUVEC) with E7, tumor necrosis factor-alpha (TNF-alpha), and hydrogen peroxide (H2O2) and measured the expression of E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) by fluorescent-activated cell sorter analysis. RESULTS E7 strongly induced the expression of E-selectin, ICAM-1, and VCAM-1 in CrMVEn, but not in HUVEC. Tumor necrosis factor-alpha further increased the endothelial expression of adhesion molecules in CrMVEn. Hydrogen peroxide pre-treatment resulted in an enhanced ICAM-1 and a decreased E-selectin and VCAM-1 expression. We also show indirect effects when endothelial cells were stimulated with the supernatant of E7-pretreated macrophages. CONCLUSIONS These results show that HPV-16-E7 oncoprotein strongly induces adhesion molecules expression in organ-specific endothelial cells.

Abstract
It has been shown recently that alpha-zearalenol, a resorcyclic acid lactone, prevents bone loss in a rat model of postmenopausal bone loss. We have therefore investigated the effects of this phytoestrogen on endothelial dysfunction induced by estrogen deficiency in rats. Female mature Sprague-Dawley rats underwent a bilateral oophorectomy (OVX rats). Sham-operated animals (sham OVX rats) were used as controls. Three weeks after surgery, animals were randomized to the following treatments: alpha-zearalenol (1 mg/kg/day, i.m., for 4 weeks), 17beta-estradiol (20 microg/kg/day, i.m., for 4 weeks), or their vehicle (100 microl, i.m., of cottonseed oil). Two other groups of rats were treated with alpha-zearalenol or 17beta-estradiol plus the pure estrogen receptor antagonist ICI 182780 (2.5 mg/kg/day, i.m., for 4 weeks). Mean arterial blood pressure (MAP), heart rate (HR), total plasma cholesterol, plasma estradiol, and plasma alpha-zearalenol were studied. We also investigated endothelial-dependent (acetylcholine, 10 nM to 10 microM) and endothelial-independent (sodium nitroprusside, 15 nM to 30 nM) relaxation of aortic rings, as well as N(G)-methyl-L-arginine (L-NMA: 10 to 100 microM)-induced vasoconstriction and calcium-dependent nitric oxide synthase (cNOS) activity in homogenates of lungs taken from both sham OVX rats and OVX rats. Untreated OVX rats had, compared with sham OVX animals, unchanged body weight, MAP, HR, and plasma cholesterol. In contrast oophorectomy reduced plasma estradiol levels (OVX, 2 +/- 0.5 pg/ml; sham OVX, 35 +/- 6 pg/ml), impaired endothelial-dependent relaxation and blunted L-NMA-induced contraction (L-NMA 100 microM: sham OVX, 2.7 +/- 0.3 g/mg tissue; OVX, 1.3 +/- 0.1 g/mg tissue). Moreover OVX rats showed a reduced calcium-dependent NO synthase (cNOS) activity. Treatment with alpha-zearalenol or with 17beta-estradiol reverted the endothelial dysfunction and increased cNOS activity in lung homogenates. These effects were abolished by the pure estrogen receptor antagonist ICI 182780. Our data suggest that alpha-zearalenol improves endothelial-dependent relaxation in OVX rats through an estrogen receptor-mediated effect.

Abstract
The authors report one case of cervical rupture in a normal uterus of a 43 years old second gravida, during an abortion at 16 weeks induced by sulprostone, a prostaglandin analogue. Case history and analysis of permittent condictions are listed. They conclude that uterus rupture remains an actual side effect of this prostaglandin E2 use, also when predisposing risk factors as scarred uterus, primigravid patients, age <20 years have been excluded, and gemeprost vaginal suppositories to ripen the cervix have been used.

Abstract
BACKGROUND Our purpose was to evaluate the clinical utility of serum uric acid measurements in the hypertension diseases of pregnancy. METHODS We identified 286 women and categorized them into three diagnostic groups according to definitions of hypertensive diseases in pregnancy published by the National Working Group on Hypertension in Pregnancy: pre-eclampsia (94), transient hypertension (102) and normal (90). We compared the median uric acid concentration for each group and calculated the sensitivities and the specificities in diagnosing pre-eclampsia. The results were analyzed by the Mann-Whitney test. RESULTS Median serum uric acid values in the pre-eclamptic group, in the transient hypertension group and in the control group were 375 (262-536) mumol/L, 309 (214-387) mumol/L, 259 (143-339) mumol/L, respectively. Compared with normal, the median serum uric acid levels in women with pre-eclampsia or transient hypertension were significantly elevated. Differences in median serum uric acid concentrations between women with preeclampsia and with transient hypertension were statistically significant too. The prevalence of IUGR in the pre-eclamptic group and transient hypertension group was 65.9% and 29.4%, respectively. Sensitivity for serum uric acid levels of 339 mumol/L was 77.3% in the pre-eclamptic group and 32.3% in the transient hypertension group; the difference was statistically significant. Specificity was exactly the same in both groups (92%). CONCLUSIONS Our data, in accordance with international literature, confirm the clinical utility of serum uric acid as a marker of pre-eclampsia, but not of transient hypertension. Furthermore its high predictive value makes it possible to select a group of pre-eclamptic women with high risk for intrauterine growth retardation.

Abstract
Expression of the inducible isoform of nitric oxide synthase (iNOS) is stimulated by cytokines in human epithelial cells. This work indicates that incubation of human umbilical cord endothelial cells with combinations of interleukin-1beta, tumor necrosis factor alpha, and interferon-gamma stimulated the synthesis of iNOS mRNA, as detected by reverse transcriptase-polymerase chain reaction. It is important to note that 50, 100, and 200 microM hydrogen peroxide was able to stimulate iNOS directly. Furthermore, 100 microM H2O2 enhanced synthesis of the oxidation products, nitrite (NO2-) and nitrate (NO3-) at 12 and 36 h. iNOS protein, detected by Western blot analysis, as well as L-citrulline levels, were also increased. When endothelial cell monolayers were incubated for 1 h with 100 microM H2O2 and subsequently with cytokines, iNOS mRNA was further augmented. Under the same conditions, we regularly observed an inhibition (25%) of intercellular adhesion molecule-1 (ICAM-1/CD54) expression. The latter was reversed when the NOS inhibitor N(G)-monomethyl-L-arginine was added, as shown by flow cytometry. These data suggest a specific effect of endogenous hydroperoxides on the biosynthesis and processing of the human endothelial iNOS isoform. We propose that H2O2 induces a temporary NO-dependent modulation of adhesion molecule expression to limit the tissue destruction that accompanies the vascular recruitment of leukocytes.

Abstract
We evaluated bcl-2 protein levels in whole blood, and intraerythrocytic products of lipoperoxidation, in 65 healthy pregnant primiparous women at the end of the first, second and third trimesters of pregnancy. During pregnancy we found a progressive increase in concentrations of bcl-2 and intraerythrocytic products of lipoperoxidation. Moreover, a positive correlation was found between bcl-2 concentrations and lipoperoxidation products, and between bcl-2 protein, E2 and progesterone. The results show that modifications occurring during pregnancy are accompanied by variations of bcl-2 protein.

Abstract
HPV-16 E6 and E7 oncoproteins impair the cell cycle in human uterine cervix carcinoma cells (HUCC) by acting on p53 and retinoblastoma proteins, respectively. We recently reported that E7 related into the extracellular compartment by HUCC SiHa cells could inhibit immune T-cell response to recall and alloantigens by a mechanism involving an overproduction of the immunosuppressive IFN alpha by antigen presenting cells (APCs). In this study, we found that besides E7, E6 protein and the vascular endothelium growth factor (VEGF) were released into the SiHa cell supernatants, and we further showed that extracellular E7 but not E6 oncoprotein 1) inhibits the immune cell response to recall and alloantigens, and 2) enhances the release of angiogenic cytokines, including TNF alpha, IL-1 beta and IL-6 by macrophages and/or dendritic cells. VEGF unexpectedly released by cancer cells could also contribute to angiogenesis. Thus in HUCC the same E7 oncoprotein which contributes to controlling the cancer cell cycle has the means in its extracellular configuration to contribute to microenvironmental immunosuppressive and angiogenic processes. Neutralizing anti-E7 antibodies either passively administered or induced by active immunization could represent a new immunotherapeutic endeavour to combat the immunosuppression and/or neoangiogenesis effects of extracellular E7 protein.

Abstract
The human papillomavirus type 16 (HPV-16) E7 oncogenic protein is found in the culture supernatant of SiHa cells, a cervical carcinoma cell line. Extracellular E7 protein, acting as a viral toxin in human immune cells, induces the overproduction of the immune suppressive IFN alpha cytokine by APCs, and inhibits the T-cell response to recall and allogenic antigens. These effects should be taken into account for the design of anti-human cervical carcinoma vaccines.

Abstract
Pre-eclampsia is the main cause of fetal and maternal morbidity and death associated with hypertension during complicating pregnancy. During physiological pregnancy, the immunological system undergoes secondary modifications, with an "exchange" between mother and fetus. Cytokines play an important role in the complex condition of partial fetal "rejection". It has suggested that the condition depend on immunological factors. In line with this hypothesis, apoptosis appear to play a key role in the pathophysiology of placental ischemia and the mechanism underlying this condition may be influenced by substances such as Bcl-2 which inhibits apoptosis. Neither aspirin nor calcium appear to improve maternal hypertension and proteinuria, although late ongoing trials may alter this view. At present, the condition can be resolved only by the end of pregnancy. Further studies are required in order to improve our understanding of these immunological mechanisms underlying hypertension during pregnancy, as the key to effective therapy may be their ability to "manipulate" them in an appropriate way.

Abstract
OBJECTIVE To establish an association of anticardiolipin antibody (ACA) levels and pre-eclampsia or intrauterine growth retardation (IUGR). METHODS Twenty-eight patients with pre-eclampsia, 28 with IUGR and 28 normotensive control group were matched for maternal age, race, weight, cigarette smoking, and parity. All had plasma anticardiolipin antibodies (GPL and MPL) detected by the modified enzyme-linked immuno-absorbent assay (ELISA) technique. RESULTS No statistical significant difference in ACA values, both GPL and MPL, was found among the three groups studied Furthermore, none reached a value of ACA that could be considered clinically relevant (> 15). CONCLUSION No association was found in anticardiolipin antibody levels between pre-eclamptic and IUGR versus the control group.

Abstract
The serum vascular adhesion molecule ICAM-1 that is involved in atherogenesis was determined in fertile, postmenopausal and at term pregnant women. The aim of the study was to ascertain if the antiatherogenic estrogens action may involve this adhesion molecule. The serum ICAM-1 concentrations resulted similar in the three groups studied: 331 +/- 35 ng/ml, 333 +/- 28 ng/ml and 302 +/- 53 ng/ml in fertile, postmenopausal and pregnant subjects respectively, despite the very different estrogen plasma levels. These data, the first on the ICAM-1 serum levels in women with different natural hormonal milieu, demonstrate that estrogens antiatherogenic action is not involving ICAM-1.

Abstract
Because of continuous blood transfusions, thalassemia patients are subjected to peroxidative tissue injury by the secondary iron overload. In accordance, analysis of serum from 42 beta-thalassemia patients, aged 4 to 40 years, showed that the mean concentrations of conjugated diene lipid hydroperoxides (CD), lipoperoxides evaluated as malondialdehyde/ thiobarbituric acid (MDA/TBA) adducts, and protein carbonyls increased about twofold with respect to control. Ferritin levels were positively correlated with the amount of MDA (r = .41; P = .007) and showed a positive trend with CD (r = .31; P = .07) and protein carbonyls (r = .35; P = .054), as further evidence of the deleterious effects of high tissue iron levels. Marked changes in the antioxidant pattern were also observed in all patients. Evidence is presented of a net drop in the concentration of ascorbate (-44%), vitamin E (-42%), vitamin A(-44%), beta-carotene (-29%), and lycopene (-67%). On the other hand, an increase of uric acid and bilirubin was observed, whereas serum albumin and glutathione were in the normal range in all patients. As a result, the total serum antioxidant potential, measured as trolox equivalent antioxidant capacity appeared significantly decreased by 14%. Serum levels of vitamin E were inversely correlated with ferritin (r = -.45; P = .003), suggesting a major consumption of this antioxidant under iron overload. Nontransferrin bound iron (NTBI) was in the range 4.5 to 54.8 micrograms/dL (mean, 21.8 +/- 13.9). Although NTBI had a positive trend with ferritin (r = .37, P = .03), no clear correlation was found with either MDA or vitamin E. A mild to severe hepatic damage, as assessed by serum transaminases, was shown in 24 of 42 patients. Serum levels of vitamin E (r = -.49, P = .015), vitamin A (r = -.48, P = .016) and lycopene (r = -.47, P = .020), were inversely correlated with the levels of transminases. On the other hand, lipid-soluble antioxidants in thalassemia patients were depleted to the same extent in hepatitis C virus (HCV)-infected (31 subjects) and in HCV-uninfected (10 subjects), while in the normal range in serum from 30 nonthalassemic patients with HCV-related chronic hepatitis. These results point out that the iron-induced liver damage in thalassemia may play a major role in the depletion of lipid-soluble antioxidants. The variations of the parameters evaluated in the present study were not correlated with the age of the patients. Our results suggest that the measurement of peroxidation products, matched with evaluation of antioxidants, may be a simple measure of iron toxicity in thalessemia, in addition to the conventional indices of iron status.
