Abstract
Postmenopausal osteoporosis stands as the predominant bone disorder in the developed world, posing a significant public health challenge. Nutritional factors play a crucial role in bone health and may contribute to its prevention or treatment. Calcium and vitamin D, extensively studied with robust scientific evidence, are integral components of the non-pharmacological treatment for this disorder. Nevertheless, other less-explored nutritional elements appear to influence bone metabolism. This review provides a comprehensive summary of the latest evidence concerning the relationship between various nutrients, such as phosphorus, magnesium, vitamins, phytate, and phytoestrogens; specific foods like dairy or soy, and dietary patterns such as the Mediterranean diet with bone health and osteoporosis.

Abstract
Objectives To assess the link between ultrasonographic measurements of the biceps brachii and total muscle mass measured by bio-impedancemetry in hospitalized older patients. Methods A prospective observational study was conducted. The study included patients older than 65 years admitted in internal medicine, acute geriatrics, orthogeriatrics and rehabilitation departments. All measurements, ultrasonographic measurements and muscle mass and function by bio-impedancemetry and dynamometry, were taken within the first 48 hours of admission. Results In total 19 patients were included, the mean age was 85.4 ± 3.9 years and 7 (36.8%) were females. Very strong direct correlations were obtained in the entire cohort in both biceps brachii cross-sectional area and muscle thickness with skeletal muscle mass displayed in kilograms. Conclusion Biceps brachii looks like a very good muscle measuring tool: easy, comfortable, fast, good correlated with total body muscle mass. This muscle could effectively be used for the assessment of muscle mass in the diagnosis of sarcopenia since it reflects muscle mass precisely, however more studies are needed to provide reference values in all age cohorts.

Abstract
The interest in the properties of animal soft tissues is often related to the desire to find an animal model to replace human counterparts due to the unsteady availability of human tissues for experimental purposes. Once the most appropriate animal model is identified, it is possible to carry out ex-vivo and in-vivo studies for the repair of ligamentous tissues and performance testing of replacement and support healing devices. This work aims to present a systematic review of the mechanical properties of ligaments reported in the scientific literature by considering different anatomical regions in humans and several animal species. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Moreover, considering the lack of a standard protocol for preconditioning of tissues, this aspect is also addressed. Ninety-six studies were selected for the systematic review and analysed. The mechanical properties of different animal species are reported and summarised in tables. Only results from studies reporting the strain rate parameter were considered for comparison with human ligaments, as they were deemed more reliable. Elastic modulus, ultimate tensile stress, and ultimate strain properties are graphically reported identifying the range of values for each animal species and to facilitate comparison between values reported in the scientific literature in animal and human ligaments. Useful similarities between the mechanical properties of swine, cow, and rat and human ligaments have been found.

Abstract
Body composition changes that occur during aging, such as loss of lean mass, are unfavorable at metabolic level and they can explain, in part, the appearance of certain age-associated diseases such as type 2 diabetes (T2D). Separately, T2D is associated with an increase in oxidative stress (OS) which negatively affects skeletal muscle. Our aim was to study the differences in clinical and nutritional parameters, disease control, and OS in a cohort of older patients with T2D classified according to the amount of lean mass they had. We included 100 adults older than 65 years with T2D. We found that women with low fat-free mass and muscle mass have worse T2D metabolic control. Moreover, the patients with a low percentile of muscle mass present a high value of OS. The study shows that the presence of low lean mass (LM) in the geriatric population diagnosed with T2D is associated with poorer glycemic control and greater OS.

Abstract
BACKGROUND AND AIMS Obesity is a key contributing factor to incidental type 2 diabetes and cardiovascular disease. CXCR3 receptor and its ligands CXCL 10 and 11 are associated with atherosclerosis and cardiovascular disease. The aim of our study was to analyse the role of the CXCR3 ligands on insulin resistance (IR) and endothelial dysfunction in human obesity. METHODS AND RESULTS We have studied 45 obese patients (mean age 44 ± 6 years, body mass index 45 ± 9 kg/m2) who were selected for Roux-Y-gastric bypass surgery and 21 non obese control subjects with similar age and gender distribution. We measured by ELISA the circulating levels of the CXCR3 ligands interferon-γ inducible protein 10 (IP-10/CXCL10) and interferon-γ-inducible T-cell alpha chemoattractant (I-TAC/CXCL11). Using an ex vivo procedure with the flow chamber assay, we have investigated the effect of such chemokines on endothelial leukocytes arrest under dynamic conditions. Peripheral blood levels of CXCL10 and CXCL11 were significantly higher in obese subjects than in controls (p < 0.001) and significantly correlated with BMI, waist circunference and HOMA-IR. Obese patients with HOMA-IR index above 75th percentile showed highest increase of circulating CXCL10 and CXCL11 values. Under dynamic flow conditions, the enhanced adhesion of patient leukocytes to TNFα-induced human arterial endothelial cells was partly dependent on CXCR3. CONCLUSIONS The study demonstrates that CXCL10 and CXCL11 are associated with IR and enhance leukocyte endothelial arrest in obese subjects. Blockade of CXCR3 signaling might be a new therapeutic approach for the prevention of obesity-associated cardiovascular co-morbidities.

Abstract
BACKGROUND Obesity is associated with high cardiovascular risk. Postprandial lipidaemia has been associated with cardiovascular disease risk. Our aim was to identify whether anthropometric parameters, insulin resistance (IR) and/or fasting plasma triglycerides may determine postprandial changes in lipoprotein concentrations in abdominal and morbid obese subjects. METHODS We have studied 20 non-diabetic, normolipidaemic subjects with abdominal obesity, 20 morbid obese subjects and 20 healthy individuals, that have similar age and gender. In all of them a standardised oral fat load test (OFLT) with unsaturated fat was performed. RESULTS During the OFLT, the postprandial triglycerides response was significantly higher in subjects with abdominal obesity compared with morbid obese subjects (4 hours triglycerides pick value and AUC of triglycerides). Both obese groups showed significantly higher postprandial triglycerides response compared with healthy subjects. Dividing the obesity group according to the presence of IR, we found that IR was an important factor related with postprandial lipaemia but not BMI or waist circumference. In addition, postprandial glycaemia and insulinaemia significantly decreased in all studied subjects, being the highest decrease in morbid obese subjects and in subjects with IR. Postprandial triglyceridaemia significantly correlated with IR parameters and not with anthropometric parameters in AO and MO subjects. CONCLUSION In subjects with AO and MO, postprandial triglycerides values are higher than healthy individuals and independently predicted by fasting IR parameters. Furthermore, unsaturated fat improved IR state.

Abstract
OBJECTIVE Post-prandial lipaemia (PL), oxidative stress (OS), and complement component C3 (C3) values are related to the atherosclerosis process. The post-prandial response of C3 after an oral fat load test (OFLT) using unsaturated fat is poorly addressed. The aim of this study was to analyze and compare the post-prandial response of OS markers and C3 values in men and women after an OFLT using unsaturated fat. METHODS The study included a total of 22 healthy subjects with normal lipids and normal blood glucose (11 men and 11 pre-menopausal women). An oral unsaturated fat load test (OFLT: 50g fat per m2 body surface) was performed using a commercial liquid preparation of long chain triglycerides (Supracal®). OS markers and C3 were measured using standardized methods at fasting state and every 2h up to 8h after the OFLT. RESULTS Men showed statistically significant higher C3, oxidized glutathione (GSSG), and oxidized-reduced glutathione (GSSG/GSH) ratio values at fasting state compared to that obtained in women. In addition, post-prandial C3 values and GSSG/GSH ratios were significantly higher in men compared to women. The GSSG value and GSSG/GSH ratio significantly decreased in men after the OFLT compared to fasting values. In contrast, the post-prandial OS markers decrease observed in women was not statistically significant. CONCLUSIONS In fasting state, men showed higher statistically significant C3 values and OS markers than women. The post-prandial OS markers (GSSG and GSSG/GSH ratio) significantly decrease after the OFLT with unsaturated fat in men compared to women.

Abstract
Background Locally advanced head and neck squamous cell carcinoma (LAHNSCC) is a heterogeneous disease in which better predictive and prognostic factors are needed. Apart from TNM stage, both systemic inflammation and poor nutritional status have a negative impact on survival. Methods We retrospectively analysed two independent cohorts of a total of 145 patients with LAHNSCC treated with induction chemotherapy followed by concurrent chemoradiotherapy at two different academic institutions. Full clinical data, including the Prognostic Nutritional Index (PNI), neutrophil to lymphocyte ratio and derived neutrophil to lymphocyte ratio, were analysed in a training cohort of 50 patients. Receiver operating characteristic curve analysis was used to establish optimal cut-off. Univariate and multivariate analyses of prognostic factors for overall survival (OS) were performed. Independent predictors of OS identified in multivariate analysis were confirmed in a validation cohort of 95 patients. Results In the univariate analysis, low PNI (PNI<45) (p=0.001), large primary tumour (T4) (p=0.044) and advanced lymph node disease (N2b-N3) (p=0.025) were significantly associated with poorer OS in the validation cohort. The independent prognostic factors in the multivariate analysis for OS identified in the training cohort were dRNL (p=0.030) and PNI (p=0.042). In the validation cohort, only the PNI remained as independent prognostic factor (p=0.007). Conclusions PNI is a readily available, independent prognostic biomarker for OS in LAHNSCC. Adding PNI to tumour staging could improve individual risk stratification of patients with LAHNSCC in future clinical trials.

Abstract
BACKGROUND Thyroid abscess or acute suppurative thyroiditis is an unusual clinical condition. We present our experience with cases attended over 41 years. MATERIALS AND METHODS A retrospective study was performed on these patients reviewing their epidemiological characteristics and the diagnostic and therapeutic manoeuvres chosen for them all, as well as their clinical outcome. A group of 9 males and 5 females was studied, with ages ranging from 19 to 68 (mean of 40.6±15.4). These patients suffered 22 acute episodes, and 2 patients each had 4 episodes. RESULTS Suppurative thyroiditis comprised 0.29% of the neck abscesses. Fine needle aspiration was performed in 13 cases to evacuate the collection and isolate the aetiological agent. Mycobacterium tuberculosis and Staphylococcus aureus were the most frequently identified. Nine patients underwent ultrasound and 7 computed tomography imaging studies. Surgery was the option for 10 patients, including drainage for 7, thyroidectomy for 4 and hemithyroidectomy for the remaining 2. Systemic or intralesional antibiotics and sclerosis of the gland were also carried out. Although one case presented with hyperthyroidism and thyrotoxicosis in the acute phase, definitive hypothyroidism was observed in 5 patients at 6 months following discharge. The rate of success was 100%. CONCLUSION Thyroid gland suppuration is a very infrequent circumstance in neck pathology, and the options for its treatment are varied, from conservative to invasive techniques according to the microbial and radiologic findings.

Abstract
BACKGROUND/AIMS Impaired angiogenesis is linked to adipose tissue (AT) dysfunction, inflammation, and insulin resistance in human obesity. Chemokine (C-X-C motif) receptor. (CXCR3) ligands are important regulators of angiogenesis in different disease contexts such as cancer; however, their role in human morbid obesity is unknown. We investigated the role of the CXCR3 axis in AT angiogenesis in morbidly obese patients. SUBJECTS/METHODS The study group comprised 50 morbidly obese patients (mean age 44 ± 1 years, body mass index 44 ± 1 kg/m2) who had undergone laparoscopic Roux-Y-gastric bypass surgery, and 25 age-matched non-obese control subjects. We measured the circulating levels of the CXCR3 ligands monokine induced by interferon-γ (MIG/CXCL9), interferon-γ inducible protein 10 (IP-10/CXCL10), and interferon-γ-inducible T-cell alpha chemoattractant (I-TAC/CXCL11) in all studied subjects. Additionally, the expression of CXCR3 ligands was analyzed in paired biopsies of subcutaneous and visceral AT obtained during the laparoscopic procedure in morbidly obese patients. Additionally, we explored the functional role of CXCR3 ligands on angiogenesis in AT from morbidly obese patients using an ex vivo assay. RESULTS Plasma levels of CXCL10 and CXCL11 were significantly higher in morbidly obese patients than in controls (p < 0.01). In ex vivo assays, angiogenic growth was markedly lower in visceral AT than in subcutaneous AT (p < 0.05), which was related to significant tissue upregulation of CXCL10, CXCL11 and CXCR3 (p < 0.05). CXCL10 or CXCL11 inhibited AT angiogenesis (p < 0.05), and blockade of CXCR3 function significantly increased capillary sprouting in visceral fat deposits (p < 0.05). Western blot analysis showed that the p38 mitogen-activated protein kinase signaling pathway was implicated in the angiostatic effects of CXCR3 in AT. CONCLUSIONS CXCL10 and CXCL11 may play. deleterious role in obesity as potential inhibitors of AT angiogenesis. Accordingly, pharmacological blockade of CXCR3 could represent. therapy to prevent AT dysfunction in obesity.

Abstract
We have designed a new synthetic strategy for the preparation of a new class of cyclic RGD integrin ligands in which the azabicycloalkane scaffold can be envisaged as a (γ,α) dipeptide mimic. The synthesis and in vitro biological evaluation of these RGD derivatives, as well as the computational study of their conformational properties and binding modes to αVβ3 integrin are described. Compound has shown to be a promising candidate as αVβ3 integrin antagonist able to interfere with both cell adhesion and movement on vitronectin with no evidence of cytotoxic effects.

Abstract
UNLABELLED Type 2 diabetes mellitus (T2DM) is a chronic, highly prevalent disease that increases with age. Because of this, and due to its chronic complications, T2DM causes high human, social, and financial costs. In addition, the elderly population with T2DM has a marked clinical heterogeneity. Therefore, our main objective was to analyze the relationship of age with the clinical and biological manifestations of the disease and the prevalence of chronic complications in patients with T2DM. MATERIAL AND METHODS A cross-sectional study of a large population with T2DM (n=405) randomly selected from a Diabetes Unit and 2 health care centers (60%). The clinical, anthropometric, and biochemical variables of the subjects were collected using standard methods to assess the effect of age on the clinical and biochemical phenotype of patients with T2DM. RESULTS We have noted that patients with T2DM > 70 years old have a clinical and biochemical phenotype different from younger subjects (<60 years) including longer times since diabetes onset, higher diastolic blood pressure levels, and lower body mass index (BMI) values. As regards to biological variables, these patients have lower triglyceride levels, impaired kidney function, and lower HbA1c values. Prevalence of metabolic syndrome is lower in patients with T2DM > 70 years of age. Age was inversely related to parameters associated to metabolic syndrome (BMI, waist circumference, blood pressure, and triglyceride levels). CONCLUSIONS We have defined the clinical and biochemical profile of patients with T2DM > 70 years attending health care centers. In addition, the prevalence of stroke, kidney disease, and distal symmetrical polyneuropathy is higher in patients with T2DM >70 years as compared to younger patients (<60 years).

Abstract
OBJECTIVE Obesity-associated nonalcoholic fatty liver disease (NAFLD), covering from simple steatosis to nonalcoholic steatohepatitis (NASH), is a common cause of chronic liver disease. Aberrant production of adipocytokines seems to play a main role in most obesity-associated disorders. Changes in adipocytokines in obesity could be mediated by alterations in cyclic GMP (cGMP) homeostasis. The aims of this work were: (1) to study the role of altered cGMP homeostasis in altered adipocytokines in morbid obesity, (2) to assess whether these alterations are different in simple steatosis or NASH, and (3) to assess whether these changes reverse in obese patients after bariatric surgery. DESIGN AND METHODS In 47 patients with morbid obesity and 45 control subjects, the levels in blood of adipocytokines, cGMP, nitric oxide (NO) metabolites, and atrial natriuretic peptide (ANP) were studied. Whether weight loss after a bariatric surgery reverses the changes in these parameters was evaluated. RESULTS NO metabolites and leptin increase (and adiponectin decreases) similarly in patients with steatosis or NASH, suggesting that these changes are due to morbid obesity and not to liver disease. Inflammation and cGMP homeostasis are affected both by morbid obesity and by liver disease. The increases in interleukin 6 (IL-6), interleukin 18 (IL-18), plasma cGMP, ANP, and the decrease in cGMP in lymphocytes are stronger in patients with NASH than with steatosis. All these changes reverse completely after bariatric surgery and weight loss, except IL-18. CONCLUSION Altered cGMP homeostasis seems to contribute more than inflammation to changes in leptin and adiponectin in morbid obesity.

Abstract
Peripheral polyneuropathy (PN) is a frequent complication of diabetes. However, mechanisms underlying the development of PN are multifactorial and not well understood. Our aim was to examine the association of plasma homocysteine (Hcy) with the prevalence and grade of peripheral PN in patients with type 2 diabetes (T2DM). We studied a cohort of 196 subjects with T2DM classified according to the grade of PN (Neuropathy Disability Score, NDS). Subjects with the highest grade of PN were older and had significantly increased levels of creatinine, microalbuminuria, HbA1c, and plasma Hcy compared to the other two groups. The differences in plasma Hcy values were maintained after correcting for confounding factors. Plasma Hcy, HbA1c, duration of diabetes, and age were predictors of the grade of PN. In conclusion, for each increase of 1 µmol in plasma Hcy there was a 23% increase of the risk of diabetic PN evaluated by NDS. Moreover, the grade of PN was predicted by plasma Hcy and HbA1c values, age and duration of diabetes. Further prospective studies should be conducted to confirm the association of plasma Hcy levels with the grade of PN in subjects with T2DM.

Abstract
To assess the contribution of hyperammonemia and inflammation to induction of mild cognitive impairment (or MHE). We analyzed the presence of mild cognitive impairment (CI) by using the PHES battery of psychometric tests and measured the levels of ammonia and of the inflammatory cytokines IL-6 and IL-18 in blood of patients with different types of liver or dermatological diseases resulting in different grades of hyperammonemia and/or inflammation. The study included patients with 1) liver cirrhosis, showing hyperammonemia and inflammation; 2) non-alcoholic fatty liver disease (NAFLD) showing inflammation but not hyperammonemia; 3) non-alcoholic steatohepatitis (NASH) showing inflammation and very mild hyperammonemia; 4) psoriasis, showing inflammation but not hyperammonemia; 5) keloids, showing both inflammation and hyperammonemia and 6) controls without inflammation or hyperammonemia. The data reported show that in patients with liver diseases, cognitive impairment may appear before progression to cirrhosis if hyperammonemia and inflammation are high enough. Five out of 11 patients with NASH, without liver cirrhosis, showed cognitive impairment associated with hyperammonemia and inflammation. Patients with keloids showed cognitive impairment associated with hyperammonemia and inflammation, in the absence of liver disease. Hyperammonemia or inflammation alone did not induce CI but the combination of certain levels of hyperammonemia and inflammation is enough to induce CI, even without liver disease.

Abstract
BACKGROUND In obesity, insulin resistance appears frequently after activation of proinflammatory molecules. Caspase-generated cytokeratin-18 (CK-18) fragments are produced during the apoptosis of hepatic cells. The main objective in the present study is to investigate the relationship between insulin resistance and caspase-generated CK-18 fragments in patients with severe obesity. METHODS Sixty-two patients selected for bariatric surgery were clinically studied (sex, age, weight, waist diameter, body mass index, arterial pressure and type 2 diabetes mellitus) and analytic parameters were measured in blood (glucose concentration, cholesterol, triglycerides, insulin, glycosylated hemoglobin, aspartate aminotransferase, alanine aminotransferase, high-sensitivity C-reactive protein, adiponectin, interleukin 6, interleukin 18 and CK-18 fragments). Patient group division was based on 70th percentile of insulin resistance as measured by homeostasis model assessment (HOMA) and also according to liver histology. RESULTS Patients with greater insulin resistance (percentile > 70th) showed higher values of CK-18 fragments, interleukin 6 and transaminases. A positive correlation between the HOMA score, value of CK-18 fragments and triglyceride level was found. A correlation between CK-18 fragments with interleukin 6, triglycerides and transaminases was also observed. HOMA score and value of CK-18 fragments correlated with the degree of liver fibrosis. CONCLUSIONS Greater degree of insulin resistance induces apoptosis of hepatic cells as measured by the serum levels of CK-18 fragments.

Abstract
BACKGROUND Few data are available on circulating mononuclear cells nuclear factor-kappa B (NF-kB) activity and plasma xanthine oxidase (XO) activity in heterozygous familial hypercholesterolaemia (FH). The goal of the study was to analyse circulating mononuclear cells NF-kB and plasma XO activities in FH patients. MATERIALS AND METHODS Thirty FH index patients and 30 normoglycaemic normocholesterolaemic controls matched by age, gender, body mass index, abdominal circumference and homeostasis model assessment index were studied. Plasma XO and inflammatory markers were measured by standard methods. NF-kB was assayed in circulating mononuclear cells. RESULTS Familial hypercholesterolaemia patients showed a significantly higher NF-kB (75.0 +/- 20.7 vs. 42.7 +/- 16.8 relative luminiscence units) and XO (0.44 +/- 0.13 vs. 0.32 +/- 0.09 mU mL(-1)) activities than controls. In addition, interleukin-1, interleukin-6, high sensitivity C reactive protein (hsCRP) and oxidized LDL (LDL-ox) were also significantly higher in FH patients. In the total group (FH and controls), XO was significantly associated with LDL-cholesterol (LDL-C), apolipoprotein B (apoB), NF-kB and hsCPR, and NF-kB activity was significantly associated with XO, hsCPR, LDL-ox, LDL-C and apoB plasma values. Using multiple regression analysis, XO was independently associated with hsCPR and NF-kB, and NF-kB activity in circulating mononuclear cells was independently associated with apoB and LDL-ox plasma values. CONCLUSION Familial hypercholesterolaemia patients show increased activities of NF-kB and XO, and higher values of low grade inflammatory markers related to atherosclerosis. NF-kB activity was independently associated with apoB plasma values. These data could explain in part the high cardiovascular disease risk present in these patients.

Abstract
AIM to investigate the association of C677T polymorphism in the methylene tetrahydrofolate reductase (MTHFR) gene, homocysteine plasma values (Hcy), and plasma HDL cholesterol in heterozy-gous familial hypercholesterolemia (hFH). METHODS One hundred and twenty-five hFH subjects were studied. Plasma lipid, lipoprotein, vitamin B12, folic acid and Hcy values were determined. C677T polymorphism in the MTHFR gene was detected by SSCP-PCR. Genetic diagnosis of FH was determined by a three-step protocol using SSCP-PCR, Southern blot, long PCR and automatic sequencing. RESULTS We found significant differences in plasma HDL-C (CC 1.39+/-0.34, CT 1.33+/-0.39 and TT 1.14+/-0.26 mmol/L, p=0.028) between the C677T MTHFR genotypes, that were also found when gender age, and BMI were included as covariables. In addition, Hcy values were significantly different between C/T MTHFR genotypes (CC 11.75+/-2.9, CT 12.69+/-2.88, TT 15.34+/-2.1 micromol/L). The distribution of gender, smoking habit and LDLR gene mutations was similar among the three groups.A significant correlation was found between Hcy plasma values and plasma HDL-C (-0.370, p= 0.003), but no correlations were found with age, BMI or other lipid and apo B plasma values. CONCLUSION In hFH subjects, the genotype TT and higher plasma Hcy levels were associated with lower HDL-C plasma values in FH subjects. More studies are needed to confirm our results and also to elucidate the exact mechanism of interaction between plasma homocysteine and lipid metabolism.

Abstract
OBJECTIVE To evaluate the efficacy and safety of the association of repaglinide, metformin and bedtime NPH insulin compared to two classic regimens: metformin plus NPH and two doses of NPH in patients with poorly controlled type 2 diabetes despite two or more oral antidiabetic drugs (OADs). PATIENTS AND METHODS Random, parallel and open study of 24 weeks with 37 patients randomized into three therapeutic groups: group A (n=12) (repaglinide/metformin/NPH), group B (n=12) (metformin/NPH) and group C (n=13) (NPH/NPH). The insulin was adjusted in the visits to obtain a basal blood glucose <110 mg/dl. The endpoint criteria included HbA1c, blood glucose profile, hypoglycemias and body weight. RESULTS At the end of the study, group A presented HbA1c (mean+/-standard deviation) 7.2+/-0.7%, which was significantly less than B (8.8+/-0.1%) and C (8.4+/-1.2%). In terms of absolute reduction, there were only differences (p=0.01) between group A (-2.4+/-1.1%) and B (-0.7+/-1.2%). Group A presented lower postprandial blood glucose values (p<0.01). Nor were there any significant differences in weight gain and incidence of hypoglycemia. CONCLUSIONS The combination of repaglinide, metformin and bedtime NPH is safe and effective and it provides better postprandial blood glucose control. The association of metformin and a dose of NPH does not obtain suitable control in patients with a long evolution who have already received two or more OADs.

Abstract
Familial hypercholesterolaemia (FH) is an autosomal dominant disease characterized by elevated levels of low-density lipoprotein-cholesterol (LDL-C). Phenotypic expression is highly variable, being influenced by diet, age, gender, body mass index, apolipoprotein E genotype and type of LDL-receptor gene mutation. Microsomal triglyceride (TG) transfer protein (MTP) is a protein involved in lipid metabolism. Polymorphism MTP -493 GT has been shown to modulate lipid levels in several populations. To analyse the effect of this polymorphism in the lipid phenotype expression of FH and treatment response, we studied a sample of 222 Spanish FH patients, of whom 147 were studied before and after treatment with 20 mg of atorvastatin daily during 6 weeks. The variant was analysed by polymerase chain reaction amplification and single-strand confirmation polymorphism. Treatment reduced LDL-C, total cholesterol and TGs. Baseline fasting TGs and very-low-density lipoprotein cholesterol levels were lower in female T allele carriers (TG: 111+/-51 mg/dl GG, 89+/-35 mg/dl GT, 83+/-26 mg/dl TT, P=0.022; very-low-density lipoprotein cholesterol: 24+/-13 mg/dl GG, 16+/-5 mg/dl GT, 17+/-5 mg/dl TT, P=0.018). Triglyceride response to atorvastatin was modulated by this polymorphism in men (P=0.009), but not in women, although differences between genotypes were maintained after treatment. In conclusion, the MTP -493 GT polymorphism modulates pre- and post-treatment plasma TG values of FH in Spanish subjects in a gender-specific way. Other environmental and genetic factors likely also modulate this response.

Abstract
Mutations underlying FH in Spain are largely unknown because only a few and limited surveys have been carried out on Spanish FH patients up to now. To gain information on this issue, we have analysed a group of 113 unrelated Spanish FH patients from an eastern area of Spain (Valencian Community). We have screened the LDLR gene by Southern blot and PCR-SSCP analysis to detect large rearrangements and small mutations, respectively. In addition, we have screened the Apo B gene for mutations known to cause FDB by PCR-SSCP analysis. We have identified a total of 47 different mutations in the LDLR gene (5 large rearrangements, and 42 small mutations, which were characterized by DNA sequencing), 19 of which have not been described in other populations (Valencia-1 to -4, 112insA, P160R, 790DelATGA, 920insTCAG, G642E, and the ten novel mutations E246A, 884delT, I289T, S305F, Q328X, Y354C, I603del, 2312-3C>A, V779M, and N804K). Three of these mutations (15%) were present in more than 1 proband, being mutation 112insA the most prevalent (frequency approximately 8%) in our sample. The Apo B gene R3500Q mutation was found in only one patient and no underlying defect was found in about 27% of patients. Our data support the notion that Spaniards represent a heterogeneous population with its own spectrum of LDLR gene mutations and that, in our population, FDB has a lower frequency or a milder expression than in central Europe countries.

Abstract
The aims of this study were to examine the presence of mutations in the low-density lipoprotein receptor gene among subjects clinically diagnosed with familial hypercholesterolemia and to analyze whether the molecular diagnosis helps to predict the response to simvastatin treatment in our familial hypercholesterolemia population. Fifty-five probands and 128 related subjects with familial hypercholesterolemia were studied. Genetic diagnosis was carried out following a three-step protocol based on Southern blot and PCR-single strand conformational polymorphism analysis. A randomized clinical trial with simvastatin was conducted in 42 genetically diagnosed subjects with familial hypercholesterolemia classified as carriers of null mutations (n = 22) and of defective mutations (n = 20). A mutation-causing familial hypercholesterolemia was identified in 46 probands (84%). In 41 of them (89%), a total of 28 point mutations were detected, 13 of which have not been previously described. The remaining five probands (11%) were carriers of large rearrangements. Familial hypercholesterolemia with null mutations showed a poor response to simvastatin treatment. The mean percentage reduction of plasma total and low-density lipoprotein cholesterol levels in these subjects were significantly lower (24.8 +/- 10.3 vs. 34.8 +/- 10.9, P = 0.04 and 30.0 +/- 39.8 vs. 46.1 +/- 18.2, P = 0.02, respectively) than in subjects with defective mutations. Baseline and posttreatment high-density lipoprotein cholesterol plasma values were significantly lower in subjects with familial hypercholesterolemia with null mutations (P < 0.001). In an outbreed Caucasian population, a three-step protocol for genetic screening detected a mutation in the low-density lipoprotein receptor gene in a high percentage (84%) of subjects with familial hypercholesterolemia. Subjects with familial hypercholesterolemia with null mutations (class I) showed lower plasma high-density lipoprotein cholesterol values and a poor low-density lipoprotein cholesterol response to simvastatin treatment.

Abstract
BACKGROUND To analyse whether the molecular diagnosis in FH patients is useful to predict the response to treatment with simvastatin in a south European population. SUBJECTS AND METHOD A randomised clinical trial with no control group, with 20 mg/day of simvastatin was conducted in 27 genetically diagnosed FH subjects (11 male) from 8 FH families, randomly selected from 30 FH families with a molecular diagnosis. Clinical features and lipid parameters at baseline and after simvastatin treatment were compared between subjects classified as null mutations (FH Valencia 1 and 2; n = 11) and defective mutations (n = 16). RESULTS FH with null mutations (FH Valencia 1 and 2) have a poor response to simvastatin treatment. The mean reduction of plasma LDLc levels in subjects with null mutations were significantly lower (32.6% [9.5] vs 42.8% [12.2]; p = 0.03) than in subjects with defective mutations. Baseline and after treatment plasma HDLc values were also significantly lower in FH group with null mutations. No statistically significant differences were found at baseline, after treatment and in the response to treatment between males and females. CONCLUSIONS FH subjects with null alleles (FH Valencia 1 and 2) showed a poor response to simvastatin treatment. The type of LDL receptor gene mutation could predict the response to simvastatin in our south European FH population.
