Abstract
PURPOSE Growth hormone deficiency (GHD) is a rare condition with a worldwide prevalence of 1 patient in 4000 to 10,000 live births, placing a significant economic burden on healthcare systems. The aim of this study is to generate evidence on the economic burden of children and adolescents with GHD treated with rhGH and their parents in Italy. METHODS A cost of illness analysis, adopting the prevalence approach, has been developed, producing evidence on the total annual cost sustained by the Italian National Health System (NHS) and by the society. The study is based on original data collected from a survey conducted among Italian children and adolescents with GHD and their parents. RESULTS 143 children/adolescents with GHD and their parents participated to the survey, conducted from May to October 2021. Patients had a mean age of 12.2 years (SD: 3.1) and were mostly males (68.5%). The average direct healthcare cost sustained by the NHS was € 8,497.2 per patient/year; adding the out-of-pocket expenses (co-payments and expenses for private healthcare service), the total expense was € 8,568.6. The indirect costs, assessed with the human capital approach, were € 847.9 per patient/year. The total of direct and indirect cost is € 9,345.1 from the NHS perspective, and € 9,416.5 from a social perspective. The total cost incurred by the Italian NHS for children with GHD (range: 5,708-8,354) was estimated in € 48.5-71.0 million, corresponding to 0.04-0.06% of the total Italian public health expense in the year 2020. CONCLUSIONS The total annual cost for GHD children is close to € 10,000, and is mainly due to the cost of rhGH treatment. This cost is almost entirely sustained by the NHS, with negligible out-of-pocket expenses. The economic burden on the Italian NHS for the health care of established GHD children is fourfold higher than the prevalence of the disease in the overall Italian population.

Abstract
PURPOSE This study aims to demonstrate a correlation between cervical spine injury and location and severity of facial trauma. METHODS We did a 10-year retrospective analysis of prospectively collected patients with at least one facial and/or cervical spine injury. We classified facial injuries using the Comprehensive Facial Injury (CFI) score, and stratified patients into mild (CFI < 4), moderate (4 ≤ CFI < 10) and severe facial trauma (CFI ≥ 10). The primary outcome was to recognize the severity and topography of the facial trauma which predict the probability of associated cervical spine injuries. RESULTS We included 1197 patients: 78% with facial injuries, 16% with spine injuries and 6% with both. According to the CFI score, 48% of patients sustained a mild facial trauma, 35% a moderate one and 17% a severe one. The midface was involved in 45% of cases, then the upper facial third (13%) and the lower one (10%). The multivariate analysis showed multiple independent risk factors for associated facial and cervical spine injuries, among them an injury of the middle facial third (OR 1.11 p 0.004) and the facial trauma severity, having every increasing point of CFI score a 6% increasing risk (OR 1.06 p 0.004). CONCLUSIONS Facial trauma is a risk factor for a concomitant cervical spine injury. Among multiple risk factors, severe midfacial trauma is an important red flag. The stratification of facial injuries based on the CFI score through CT-scan images could be a turning point in the management of patients at risk for cervical spine injuries before imaging is available.

Abstract
BackgroundPsoriatic Arthritis (PsA) is a chronic inflammatory disease, characterized by both articular and periarticular manifestations, usually associated with psoriasis. The identification of the correct therapy for patients is still a critical issue, but the use of biological drugs, such as TNFi (Tumor Necrosis Factor Inhibitors), modified the outcome of PsA patients even if there is great variability in the clinical efficacy. Since the response to drugs is a complex trait, the identification of genetic factors could help to define new genomic biomarkers for more effective and personalized therapy.ObjectivesThe aim of this study was to evaluate the potential role of polymorphisms in genes already known to be involved in PsA susceptibility (ERAP1, HCP5, IL10, MIR146, PSORS1C1, STAT4, TNFAIP3 and TRAF3IP2) as predictors of efficacy of treatment, in a cohort of Italian PsA patients, treated with first-line TNF-i, in particular with Etanercept (ETN) and Adalimumab (ADA).MethodsPolymorphisms were analyzed in a cohort of 163 patients with peripheral PsA. For each patient was estimated the Disease Activity in Psoriatic Arthritis (DAPsA) score. Genotyping was performed by allelic discrimination by TaqMan assay. The possible association between the selected SNPs and mean values of DAPsA differences, at 22 (ΔT22) and 54 (ΔT54) weeks from the beginning of the TNF-i treatment, were evaluated by T-test. A multivariate logistic regression analysis was used to evaluate the contribution of each genetic variant investigated in the TNF-i treatment response.ResultsWe have observed that TRAF3IP2 SNP was associated with TNF-i treatment response in PsA patients. In particular, the patients carrying variant alleles seem to respond better to treatment, both at 22 (P = 0.032) and 54 weeks (P = 0.019). Moreover, the variant allele of TRAF3IP2 SNP resulted associated with a better response of joints involvement. Indeed, the number of tender and swollen joints decrease more in patients carrying variant allele (P = 0.006 and P = 0.024, respectively). We also observed that PsA patients carrying IL10 variant allele decrease their mean DAPsA value less than patients with wild-type genotype only at 54 weeks of treatment (P = 0.031). Also, HCP5 polymorphism showed a difference of mean difference of DAPsA values between genotypes for both follow up, even if these difference does not reach a statistical significance (P = 0.068 and P = 0.086). The multivariate regression analysis was performed with a stepwise method and it confirmed the involvement of TRAF3IP2 (P = 0.016) and HCP5 (P = 0.035) polymorphisms in the TNF-i response after 22 weeks and of TRAF3IP2 (P = 0.007), IL10 (P = 0.022) and HCP5 (P = 0.036) polymorphisms after 54 weeks. The two final models explain about 6% and 11% of the variability in TNF-i treatment response at 22 and 54 weeks respectively.ConclusionOur results suggest that some polymorphisms in genes associated to PsA susceptibility could also play a role in TNFi treatment response and could give a contribution in the definition of a genetic profile associated with the response to anti-TNF drugs.Figure 1.Mean differences of DAPsA values in the genotypic classes for TRAF3IP2, IL10 and HCP5 SNPs.

Abstract
Recently, a strong correlation between metabolic disorders, tumor onset, and progression has been demonstrated, directing new therapeutic strategies on metabolic targets. OLR1 gene encodes the LOX-1 receptor protein, responsible for the recognition, binding, and internalization of ox-LDL. In the past, several studied, aimed to clarify the role of LOX-1 receptor in atherosclerosis, shed light on its role in the stimulation of the expression of adhesion molecules, pro-inflammatory signaling pathways, and pro-angiogenic proteins, including NF-kB and VEGF, in vascular endothelial cells and macrophages. In recent years, LOX-1 upregulation in different tumors evidenced its involvement in cancer onset, progression and metastasis. In this review, we outline the role of LOX-1 in tumor spreading and metastasis, evidencing its function in VEGF induction, HIF-1alpha activation, and MMP-9/MMP-2 expression, pushing up the neoangiogenic and the epithelial-mesenchymal transition process in glioblastoma, osteosarcoma prostate, colon, breast, lung, and pancreatic tumors. Moreover, our studies contributed to evidence its role in interacting with WNT/APC/β-catenin axis, highlighting new pathways in sporadic colon cancer onset. The application of volatilome analysis in high expressing LOX-1 tumor-bearing mice correlates with the tumor evolution, suggesting a closed link between LOX-1 upregulation and metabolic changes in individual volatile compounds and thus providing a viable method for a simple, non-invasive alternative monitoring of tumor progression. These findings underline the role of LOX-1 as regulator of tumor progression, migration, invasion, metastasis formation, and tumor-related neo-angiogenesis, proposing this receptor as a promising therapeutic target and thus enhancing current antineoplastic strategies.

Abstract
Systemic lupus erythematosus (SLE) is a common heterogeneous autoimmune disease that is caused by the involvement both of genetic and environmental factors. There is evidence that autophagy is involved in several aspects of SLE pathogenesis. In particular, polymorphisms in the ATG5 gene have been observed to be associated with disease susceptibility. Our aim was to verify if ATG5 polymorphisms are involved in the susceptibility to disease and its clinical phenotypes in an Italian cohort of SLE patients. This study involved 315 SLE patients and 265 healthy controls. Three polymorphisms in the ATG5 gene (rs573775, rs6568431 and rs2245214) were investigated by allelic discrimination assay. A case-control association study, a genotype/phenotype correlation analysis and a haplotype study were performed. Moreover, an expression study was conducted in peripheral blood mononuclear cells from 15 SLE patients to verify a possible effect of the three SNPs on the expression of ATG5. Among the three investigated SNPs, only the rs573775 SNP was significantly associated with disease susceptibility with the variant allele conferring a higher risk of developing SLE (OR = 1.50, p = 0.018 and OR = 1.48, p = 0.007 at the genotypic and allelic level, respectively). The variant allele of rs6568431 SNP was more present in patients with anemia (OR = 1.86, p = 0.009) and renal involvement (OR = 1.63, p = 0.06), while the variant allele of rs2245214 SNP was significantly associated with a higher risk of producing anti-DNA autoantibodies (OR = 1.66, p = 0.04). Carriers of the rs6568431 variant allele showed higher messenger RNA levels compared to the carriers of the wild-type allele, suggesting also a potential variant allele dose-dependent effect on gene expression. In conclusion, our study confirms a role for ATG5 polymorphisms both in disease susceptibility and in the modulation of clinical phenotypes in an Italian SLE cohort. These results further suggest that genetic variations in autophagy genes could play a role in autoimmune diseases susceptibility and are worth further investigation.

Abstract
Myotonic Dystrophy type 1 (DM1) is the most common form of muscular dystrophy in adults, characterized by a variety of multisystemic features and associated with cardiac anomalies. Among cardiac phenomena, conduction defects, ventricular arrhythmias, and dilated cardiomyopathy represent the main cause of sudden death in DM1 patients. Patient-specific induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) represent a powerful in vitro model for molecular, biochemical, and physiological studies of disease in the target cells. Here, we used an Atomic Force Microscope (AFM) to measure the beating profiles of a large number of cells, organized in CM clusters (Beating Bodies, BBs), obtained from wild type (WT) and DM1 patients. We monitored the evolution over time of the frequency and intensity of the beating. We determined the variations between different BBs and over various areas of a single BB, caused by morphological and biomechanical variations. We exploited the AFM tip to apply a controlled force over the BBs, to carefully assess the biomechanical reaction of the different cell clusters over time, both in terms of beating frequency and intensity. Our measurements demonstrated differences between the WT and DM1 clusters highlighting, for the DM1 samples, an instability which was not observed in WT cells. We measured differences in the cellular response to the applied mechanical stimulus in terms of beating synchronicity over time and cell tenacity, which are in good agreement with the cellular behavior in vivo. Overall, the combination of hiPSC-CMs with AFM characterization can become a new tool to study the collective movements of cell clusters in different conditions and can be extended to the characterization of the BB response to chemical and pharmacological stimuli.

Abstract
PurposeThe goal was to develop a simple model for predicting the individual risk profile for age-related macular degeneration (AMD) on the basis of genetic information, disease family history, and smoking habits.Patients and methodsThe study enrolled 151 AMD patients following specific clinical and environmental inclusion criteria: age >55 years, positive family history for AMD, presence of at least one first-degree relative affected by AMD, and smoking habits. All of the samples were genotyped for rs1061170 (CFH) and rs10490924 (ARMS2) with a TaqMan assay, using a 7500 Fast Real Time PCR device. Statistical analysis was subsequently employed to calculate the real individual risk (OR) based on the genetic data (ORgn), family history (ORf), and smoking habits (ORsm).Results and conclusionThe combination of ORgn, ORf, and ORsm allowed the calculation of the Ort that represented the realistic individual risk for developing AMD. In this report, we present a computational model for the estimation of the individual risk for AMD. Moreover, we show that the average distribution of risk alleles in the general population and the knowledge of parents' genotype can be decisive to assess the real disease risk. In this contest, genetic counseling is crucial to provide the patients with an understanding of their individual risk and the availability for preventive actions.

Abstract
Myotonic dystrophy type 1 (DM1) is a multisystem neuromuscular disease caused by a CTG triplet expansion in the 3'-untranslated region (3'-UTR) of DMPK gene. This CTG array is usually uninterrupted in both healthy and DM1 patients, but recent studies identified pathological variant expansions containing unstable CCG, CTC and CGG interruptions with a prevalence of 3-5% of cases. In this review, we will describe the clinical, molecular and genetic issues related to the occurrence of variant expansions associated with DM1. Indeed, the identification of these complex DMPK alleles leads to practical consequences in DM1 genetic counseling and testing, because these exams can give false negative results. Moreover, DM1 patients carrying interrupted alleles can manifest either additional atypical neurological symptoms or, conversely, mild, late-onset forms. Therefore, the prognosis of the disease in these patients is difficult to determine because of the great uncertainty about the genotype-phenotype correlations. We will discuss the putative effects of the variant DM1 alleles on the pathogenic disease mechanisms, including mitotic and meiotic repeats instability and splicing alteration typical of DM1 tissues. Interruptions within the DMPK expanded alleles could also interfere with the chromatin structure, the transcriptional activity of the DM1 locus and the interaction with RNA CUG-binding proteins.

Abstract
Recently, a study has shown that a polymorphism in the region of MIR1279 modulates the expression of the TRAF3IP2 gene. Since polymorphisms in the TRAF3IP2 gene have been described in association with systemic lupus erithematosus (SLE) susceptibility and with the development of pericarditis, our aim is to verify if the MIR1279 gene variability could also be involved. The rs1463335 SNP, located upstream MIR1279 gene, was analyzed by allelic discrimination assay in 315 Italian SLE patients and 201 healthy controls. Moreover, the MIR1279 gene was full sequenced in 50 patients. A case/control association study and a genotype/phenotype correlation analysis were performed. We also constructed a pericarditis genetic risk profile for patients with SLE. The full sequencing of the MIR1279 gene in patients with SLE did not reveal any novel or known variation. The variant allele of the rs1463335 SNP was significantly associated with susceptibility to pericarditis ( P = 0.017 and OR = 1.67). A risk profile model for pericarditis considering the risk alleles of MIR1279 and three other genes (STAT4, PTPN2 and TRAF3IP2) showed that patients with 4 or 5 risk alleles have a higher risk of developing pericarditis ( OR = 4.09 with P = 0.001 and OR = 6.04 with P = 0.04 respectively). In conclusion, we describe for the first time the contribution of a MIR1279 SNP in pericarditis development in patients with SLE and a genetic risk profile model that could be useful to identify patients more susceptible to developing pericarditis in SLE. This approach could help to improve the prediction and the management of this complication.

Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease resulting in chronic inflammation of the synovium and consequent cartilage and bone erosion. RA is associated strongly with the presence of rheumatoid factor (RF), and consists of clinical subsets of anti-citrullinated protein antibody (ACPA)-positive and -negative patients. This study was designed to evaluate whether relevant single nucleotide polymorphisms (SNPs) associated with RA and other autoimmune disorders are related to RF, ACPA and clinical phenotype in a cohort of biologic drugs naive Italian RA patients; 192 RA patients and 278 age-matched healthy controls were included. Clinical and laboratory data were registered. We analysed a total of 12 single nucleotide polymorphisms (SNPs) in signal transducer and activator of transcription-4 (STAT-4), interleukin (IL)-10, psoriasis susceptibility 1 candidate 1 (PSORS1C1), protein tyrosine phosphatase, non-receptor type 2 (PTPN2), endoplasmic reticulum aminopeptidase 1 (ERAP1), tumour necrosis factor receptor-associated 3 interacting protein 2 (TRAF3IP2) and microRNA 146a (MIR146A) genes by allelic discrimination assays. Case-control association studies and genotype/phenotype correlation analyses were performed. A higher risk to develop RA was observed for rs7574865 in the STAT-4 gene, while the rs1800872 in the IL-10 gene showed a protective effect. The presence of RF was associated significantly with rs1800872 variant in IL-10, while rs2910164 in MIR146A was protective. ACPA were associated significantly with rs7574865 in STAT-4. The SNP rs2233945 in the PSORS1C1 gene was protective regarding the presence of bone erosions, while rs2542151 in PTPN2 gene was associated with joint damage. Our results confirm that polymorphisms in STAT-4 and IL-10 genes confer susceptibility to RA. For the first time, we described that SNPs in PSORS1C1, PTPN2 and MIR146A genes were associated differently with a severe disease phenotype in terms of autoantibody status and radiographic damage in an Italian RA population.

Abstract
OBJECTIVE Blepharophimosis syndrome (BPES) is an autosomal dominant genetic condition resulting from heterozygous mutations in the FOXL2 gene and clinically characterized by an eyelid malformation associated (type I) or not (type II) with premature ovarian failure. The distinction between the two forms is critical for female patients, as it may allow to predict fertility and to plan an appropriate therapy. Identifying an underlying causative mutation is not always predictive of the clinical type of BPES since genotype-phenotype correlations are not yet fully delineated. Here, we describe the clinical and hormonal phenotypes of three female patients with BPES type 1 from two novel families, correlate their phenotypes with identified mutations, and investigate the effects of hormone replacement therapy (HRT). METHODS Clinical, biochemical, and genetic evaluation were undertaken in all the patients and genotype-phenotype correlation was analyzed. The effects of substitutive hormonal therapy on secondary sexual characteristics development and induction of menarche were evaluated. RESULTS All patients presented with primary amenorrhea or other signs of ovarian dysfunction. Two distinct mutations, a missense p.H104R change and an in-frame p.A222_A231dup10 duplication in the FOXL2 gene were identified. Observed phenotypes were not in accordance with the prediction based on the current genotype-phenotype correlations. HRT significantly improved secondary sexual characteristics development, as well as the induction of menarche. CONCLUSIONS This study highlights the importance of early recognition of BPES and emphasizes the need of personalized therapy and follow-up in female patients carrying distinct FOXL2 mutations.

Abstract
Classical galactosemia is an autosomal recessive inborn error of metabolism due to mutations of the GALT gene leading to toxic accumulation of galactose and derived metabolites. With the benefit of early diagnosis by neonatal screening and early therapy, the acute presentation of classical galactosemia can be prevented. However, despite early diagnosis and treatment, the long term outcome for these patients is still unpredictable because they may go on to develop cognitive disability, speech problems, neurological and/or movement disorders and, in females, ovarian dysfunction. The objectives of the current study were to report our experience with a group of galactosemic patients identified through the neonatal screening programs in northeastern Italy during the last 30years. No neonatal deaths due to galactosemia complications occurred after the introduction of the neonatal screening program. However, despite the early diagnosis and dietary treatment, the patients with classical galactosemia showed one or more long-term complications. A total of 18 different variations in the GALT gene were found in the patient cohort: 12 missense, 2 frameshift, 1 nonsense, 1 deletion, 1 silent variation, and 1 intronic. Six (p.R33P, p.G83V, p.P244S, p.L267R, p.L267V, p.E271D) were new variations. The most common variation was p.Q188R (12 alleles, 31.5%), followed by p.K285N (6 alleles, 15.7%) and p.N314D (6 alleles, 15.7%). The other variations comprised 1 or 2 alleles. In the patients carrying a new mutation, the biochemical analysis of GALT activity in erythrocytes showed an activity of <1%. In silico analysis (SIFT, PolyPhen-2 and the computational analysis on the static protein structure) showed potentially damaging effects of the six new variations on the GALT protein, thus expanding the genetic spectrum of GALT variations in Italy. The study emphasizes the difficulty in establishing a genotype-phenotype correlation in classical galactosemia and underlines the importance of molecular diagnostic testing prior to making any treatment.

Abstract
INTRODUCTION Acute-on-chronic liver failure (ACLF) is a systemic inflammatory reaction, which is characterized by a predominantly proinflammatory cytokine profile, causing the transition from stable cirrhosis to ACLF. The aim of the present study was to evaluate the changes in several cytokines associated with inflammatory liver disease and liver regeneration among 15 ACLF patients treated with the Molecular Adsorbent Recirculating System (MARS) compared with 15 patients treated with standard medical therapy (SMT). The subjects showed various disease etiologies but similar values for Model End-stage Liver Disease scores. METHODS In the MARS group, 15 (10 male and 5 female) patients were treated with MARS (Gambro). The number of MARS applications was nine; the length of applications was 8 hours. In the SMT group; 15 (10 male and 5 female) patients were treated with SMT. The patients were monitored for 30 days from inclusion with a survival follow-up at 3 months. Statistical results were calculated with SPSS14.0 (SPSS Inc, Chicago, Ill). A P < .07 was considered significant. RESULTS In the MARS group, we observed significant changes in the levels of Interleukin (IL)-6, IL-1, IL-10, and tumor necrosis factor (TNF)-alpha in association with improved hepatocyte growth factor. Patient survival at 3 months was 60%. The SMT group showed only a significant change in TNF-alpha (P = .03). Patient survival at 3 months was 30%. CONCLUSION The MARS liver support device corrected pathophysiologies of ALF and may be used to enhance spontaneous recovery or as a bridge to transplantation.

Abstract
We analyzed predictive risk factors for recurrence of hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). We retrospectively analyzed the clinical data from 109 consecutive HCC patients who underwent OLT at our center from 1988 to 2007. We excluded all patients who died due to factors other than tumor recurrence within the first year (n = 24). The remaining 85 patients were enrolled in either a recurrence group (A; n = 19) or a nonrecurrence group (B; n = 66). Upon univariate analysis, the 2 groups were significantly different for 11 parameters. Group A included more females (P = .05), noncirrhotic liver recipients (P = .003), "up-to 7 status" patients (HCC with 7 as the sum of the size of the largest tumor [cm] and the number of tumors, P < .0001), patients exceeding Milan criteria (MC; P < .0001) or University of California San Francisco (UCSF) criteria (P < .0001), and OLT performed before 1999 (P = .003). Group A also showed a higher number of lesions (P = .035), a greater sum of diameters of the lesions (P < .0001), a major number of macrovascular (P < .0001) and microvascular invasions (P < .0001), and an increased number of G3-G4 grading (P = .006). Only microvascular invasion (P = .007) and exceeding UCSF criteria (P = .003) were independent risk factors for recurrence upon multivariate analysis. Patients with both these parameters are not candidates for OLT. Microvascular invasion is a good predictive parameter, but is impossible to detect preoperatively. New pre-OLT predictive risk factors are needed to achieve optimal results.

Abstract
BACKGROUND Various biomarkers have been studied for diagnosing bacterial infections, seeking to stop the sepsis cascade. Presepsin, which is ∼13 kDa in size, has been identified to increase specifically in the blood of sepsis patients. Additionally, measurement of presepsin is useful to evaluate the severity of infection and monitor clinical responses. We evaluated the analytical and clinical performance of the Pathfast presepsin (PFP) assay system for early diagnosis of infection. MATERIALS AND METHODS From November 2011 to June 2012 we studied 70 adult patients, including 35 cadaveric organ transplant recipients and 35 abdominal surgery patients. The 32 female and 38 male subjects had a mean age of 56.1 years (range, 19-70). Heparinized whole blood for PFP assay was tested at 48 hours after surgery together with blood cultures. RESULTS The mean presepsin level (PL) in the 50 positive patients was 3,957.45 pg/mL (range 255-20,000). For transplant patients, PL was 3,034.43 ± 2,880.791 pg/mL, with 30 positive results. Microbiologic findings confirmed the presence of bacterial infections within 69 ± 2.5 hours from enrollment despite that when the test was performed, 70% showed no sign or symptom of infection. In 15 abdominal surgery patients, the PFP test was negative with negative blood cultures. The positive PFP test in 20 other abdominal surgery patients showed PL of 2,363 ± 7,988.47 pg/mL in the absence of signs or symptoms of infection in 25% of them. The 20 positive patients showed positive blood cultures within 67 ± 1.8 hours from enrollment. CONCLUSIONS The PFP test had a (100%) sensitivity to show the presence of infection in a short time (15 min), confirmed by positive blood cultures.

Abstract
We analyzed two West African samples (Guinea-Bissau: n=289 cases and 322 controls; The Gambia: n=240 cases and 248 controls) to evaluate single-nucleotide polymorphisms (SNPs) in Epiregulin (EREG) and V-ATPase (T-cell immune regulator 1 (TCIRG1)) using single and multilocus analyses to determine whether previously described associations with pulmonary tuberculosis (PTB) in Vietnamese and Italians would replicate in African populations. We did not detect any significant single locus or haplotype associations in either sample. We also performed exploratory pairwise interaction analyses using Visualization of Statistical Epistasis Networks (ViSEN), a novel method to detect only interactions among multiple variables, to elucidate possible interaction effects between SNPs and demographic factors. Although we found no strong evidence of marginal effects, there were several significant pairwise interactions that were identified in either the Guinea-Bissau or the Gambian samples, two of which replicated across populations. Our results indicate that the effects of EREG and TCIRG1 variants on PTB susceptibility, to the extent that they exist, are dependent on gene-gene interactions in West African populations as detected with ViSEN. In addition, epistatic effects are likely to be influenced by inter- and intra-population differences in genetic or environmental context and/or the mycobacterial lineages causing disease.

Abstract
Necrotizing fasciitis is a rare polymicrobial, infection, characterized by a rapid and destructive spread within the subcutaneous tissue and along the superficial fascial planes, initially not affecting underlying muscles but with a common systemic involvement. Necrotizing fasciitis confined to the cervico-facial region is extremely rare (10% of cases) and is characterized by a high mortality rate due to airway compromise and to involvement of the supra-aortic vessels. The prognosis for survival is based on the severity of the necrotizing fasciitis, on the patient's systemic condition and on the prompt diagnosis and adequate surgical and medical management. We discuss a case of cervico-facial necrotizing fasciitis in a 25-year-old patient beginning with an odontogenic abscess, resistant to antibiotic therapy, rapidly progressing into an important right-sided swelling of the neck with worsening dyspnea and dysphagia. Because of his worsened general condition, the patient was transferred to the operating room for an emergency treatment. Under general anesthesia, the right cervical and left buccal purulent material was drained via right lateral cervicotomy an aggressive debridement of necrotic tissue, a disruption and excision of the all-necrotic fascia and a removal of the right submandibular gland. Thus, a portable mini-VAC device was applied. The early intervention with a specific diagnostic and therapeutic protocol and the wound treatment by means of vacuum assisted closure therapy allowed to obtain a quick healing, preventing the systemic involvement, minimizing morpho-esthetic outcome and limiting the costs of post-operative wound care.

Abstract
In this review, we focus on current information on the apheresis procedures for endotoxins removal with Polymyxin B cartridges (PMX). This device has been designed in 2003 in Japan in order to take advantage of the antibiotic effects of Polymyxins on Gram negative bacteria and endotoxins, by-passing the toxicity shown by the intravenous administration. Although its mechanisms of action are nowadays well-known, we felt the need to sum up all the someway scattered information giving an overall sight on the entire process that brings Polymyxins molecules to function as powerful detergents of the endotoxins from the blood flow. Since the first experiences on humans, over one hundred studies have been published about the clinical use of this device. Even if some of them were limited in number of patients and compliance to international standards, they all converged in showing a highly positive impact of PMX on the improvement of clinic condition and outcome. Recently, more significant and large experiences confirmed the benefits of this treatment on hemodynamic, PaO2/FiO2 ratio, APACHE and SOFA scores and outcome at 28 days even on different typologies of sepsis cases, such as in transplanted patients. Summarizing, this relatively new procedure has proven to be a promising tool against Gram negative and endotoxin sepsis, combining clinical and outcome improvements with a fair cost/effectiveness ratio. Given that, there's still need of wider and more structured clinical studies that could steady the use of this device and widen its fields of applications.

Abstract
BACKGROUND Nowadays 7,000 rare diseases (RDs) have been identified with a prevalence less than 5/10,000. Despite of the enormous effort the European Union (EU) has already invested in this field, still 4,000 RDs remain orphan of genetic diagnosis and causative gene identification. The genetic definition of RDs represents a prerequisite for being diagnosed, for having a robust prevention, for entering in a specific standard of care, and ultimately, for being included in clinical trials, often via personalized medicine. It is well established that biomarkers can offer a way to speed up research by understanding the pathophysiological mechanisms of diseases. In particular, biomarkers will offer an invaluable tool for monitoring disease progression, prognosis and response to drug treatment. METHODS In this review, we summarize the different types of biomarkers and their importance as well as their translational applications in RDs. We have reviewed the current knowledge on biomarkers state-of-the-art via literature data, specific websites and EU sources regarding past, pending and current projects. RESULTS Here we provide a comprehensive scenario of biomarkers research, its applications in clinical practice, with special emphasis on translational research applicable to diagnostic and clinical trials. The experience of the EU project BIO-NMD is also mentioned. CONCLUSION Biomarkers represent key features in both diagnostics and research on rare diseases and will encounter wide exploitation in translational and personalized medicine.

Abstract
BACKGROUND Atopic eczema (AE) (OMIM %603165) is the most common chronic inflammatory skin disease characterized by xerosis, pruritus, and erythematous lesions with increased transepidermal water loss. It's a complex disease due to the interaction between environmental and genetics factors. To date, different loci have been related to the disease. OBJECTIVES To verify the association, between AE and rs479844, rs2164983, and rs2897442, target for OVOLI (11q13), ACTL9 (19p13.2), and in KIF3A (5q31) genes in the Italian population. Recently, these SNPs have been validated as associated to the disease. METHODS A case-control study testing a cohort of 359 AE cases and 778 controls. RESULTS We confirmed the association between rs2897442 in KIF3A gene and the disease at both allele and genotype level (P-value: 4.8 × 10(-4) and P-value: 6.3 × 10(-4), respectively). The C allele of the SNP showed an Odds Ratio (OR) of 1.46 (95% CI 1.18-1.82), moreover the CC genotype achieved an OR of 2.77 (95% CI 1.66-4.61). We failed to reveal association between AE and the other two SNPs tested. CONCLUSIONS Our study indicated KIF3A as a novel gene implicated in the development of AE in the Italian population.

Abstract
We tried to identify molecular markers in peripheral blood to predict high risk of aneurysm rupture. Extraction of the total population of peripheral blood mononuclear cell (PBMC) from total blood volume, total RNA extraction from PBMC and Agilent One Color Gene-expression Oligo-Microarray were performed on peripheral venous blood samples from 45 patients with ruptured, unruptured cerebral aneurysms and control group (15). Mean foreground/ background signal intensities and A (log2(R*G)/2) values were calculated for each spot. Genes with absolute fold change (FC) greater than or equal to plus or minus 1.5 and p-value less than 0.05 were considered differentially expressed in the 3 groups (Student T-test). Genes coding for MMPs were strongly underexpressed in ruptured aneurysms group, suggesting a possible role in aneurysms development more than their rupture. Genes coding for adhesine proteins of the extracellular matrix (ICAM1) and cytoskeleton (WIPF1,TUBA4A) were underexpressed in ruptured aneurysms. Genes coding proteins involved in the regulation of apoptotic processes may be important in aneurysm development and rupture, resulting into an increased rate of remodeling processes in the arterial wall. Fas coding gene, SUMO1, ZFAT, BCL2, CCR5 genes were all over-represented in unruptured aneurysms. The coexisting over-representation of pro-apoptotic genes and the underexpression of cytoskeleton and extracellular matrix genes confirms that aneurysms development and evolution are part of a degenerative process of the arterial wall not involved in aneurysms rupture. MMPs may be involved in repairing chronic damages to the arterial walls and preventing SAH. Unexpectedly, Heat Shock Proteins (HSP90AA1, HSPA1A, HSPB1), G and RAS proteins, generally activated by stress situations were under-represented in aneurysmal walls. Further PCR and Western Blotting studies are needed to confirm such findings and to identify diagnostic and prognostic markers in order to define screening protocols for intracranial aneurysms.

Abstract
The first endpoint of this study was to find new markers that document the progression of hepatic steatosis through quantitative histomorphometric analysis in the absence of hemodynamic changes. The second endpoint was to start building a mathematical database to help to achieve a score in the future. For this study we enrolled 130 random patients, including 10 with normal histology despite suspected disease, 70 positive for steatosis, 20 affected by nonalcoholic steato hepatitis, and 30 with hepatitis virus C or B-related cirrhosis. One hundred thirty images were analyzed for a total of 1,320 sinusoids. Each image was processed with a custom program written with the use of the Vision toolbox of the Labview platform, following a semiautomated procedure. The mean sinusoidal areas (SAs) and percentage fractions of parenchymal area occupied by sinusoids (SA/PA) were subdivided into 3 groups. Finally, we analyzed the form of sinusoids, approximating them to an ellipse, to be able to define the relationship between the 2 axes with the aim of proposing a parameter, "local hydraulic resistance" (LHR), that was proportional to the resistance to blood flow within the bounds of the histologic specimen. Among the images, we observed a difference in the size of SAs among the 3 groups of patients, namely, normal, steatotic of different stages, and cirrhotic patients. In fact, there was evidence of a reducted SA when steatosis was <30%, with an average value of 0.0032 mm(2), patients with steatosis of 30%-50% showed an average SA of 0.0024 mm(2), and there was a further reduction among subjects with steatosis grades >50% (mean 0.0017 mm(2)). The LHR value showed that the morphometric parameter SA/PA could be quantitatively interpreted also as a functional impairment relative to the increased resistance opposing blood flow in pathologic conditions.

Abstract
The fundamental role of antibodies in the development of acute graft rejection has been established recently. Antibody-mediated acute rejection may develop at any time during the post-transplant period. Several therapeutic approaches have been proposed in the last decades. However, there is no standardized therapy. The aim of this study is to report the Sapienza University experience of combined plasma treatment and high-dose intravenous immunoglobulin ± extracorporeal photopheresis. From January 2006 to September 2009, 6 patients were treated at Sapienza University. In 5 cases (83%) complete regression of the acute rejection was observed, followed by stable renal function (median creatinine value at 1-year follow-up: 1.5 mg/dL). No adverse events were reported. Our approach seems to give good results in terms of graft survival and procedure safety. Further studies on a larger number of patients will be needed to confirm the validity of these findings. Moreover, comparison between our protocol and other treatments is necessary.

Abstract
Hepatitis C virus (HCV) infection occurs much more frequently in the hemodialysis population than in the general population. Patients with chronic kidney disease with persistent HCV infection may develop serious and progressive chronic liver disease, with associated long-term morbidity and mortality related to cirrhosis and hepatocellular carcinoma. Monocytes and macrophages are known to produce extrahepatic breeding sites and spread the disease. Our aim was to lower the levels of macrophages, granulocytes, monocytes, proinflammatory cells and viremia using an extracorporeal device: the Adacolumn ® leukocyte apheresis system (Otsuka). The Adacolumn is a direct hemoperfusion-type leukapheresis device. The column is a single-use (disposable) polycarbonate column with a capacity of about 335 mL, filled with 220-g cellulose acetate beads of 2 mm in diameter bathed in physiological saline. The carriers adsorb ''activated'' granulocytes and monocytes/macrophages that bear Fc and complement receptors. The patients underwent five 1-hour sessions for five consecutive days. The column was placed in an extracorporeal setting with a perfusion rate of 30 mL/min and a duration of 60 minutes. A reduction of viremia was observed in all patients in association with a decrease in cytokine levels and a proportional decrease in immune cells. Although this study investigated responses in a small number of patients, it was shown that the Adacolumn changed the cellular immunity and promoted early viral response.

Abstract
Farnesylated prelamin A is a processing intermediate produced in the lamin A maturation pathway. Accumulation of a truncated farnesylated prelamin A form, called progerin, is a hallmark of the severe premature ageing syndrome, Hutchinson-Gilford progeria. Progerin elicits toxic effects in cells, leading to chromatin damage and cellular senescence and ultimately causes skin and endothelial defects, bone resorption, lipodystrophy and accelerated ageing. Knowledge of the mechanism underlying prelamin A turnover is critical for the development of clinically effective protein inhibitors that can avoid accumulation to toxic levels without impairing lamin A/C expression, which is essential for normal biological functions. Little is known about specific molecules that may target farnesylated prelamin A to elicit protein degradation. Here, we report the discovery of rapamycin as a novel inhibitor of progerin, which dramatically and selectively decreases protein levels through a mechanism involving autophagic degradation. Rapamycin treatment of progeria cells lowers progerin, as well as wild-type prelamin A levels, and rescues the chromatin phenotype of cultured fibroblasts, including histone methylation status and BAF and LAP2α distribution patterns. Importantly, rapamycin treatment does not affect lamin C protein levels, but increases the relative expression of the prelamin A endoprotease ZMPSTE24. Thus, rapamycin, an antibiotic belonging to the class of macrolides, previously found to increase longevity in mouse models, can serve as a therapeutic tool, to eliminate progerin, avoid farnesylated prelamin A accumulation, and restore chromatin dynamics in progeroid laminopathies.

Abstract
Hirsutism is the development of androgen-dependent terminal body hair in women in places in which terminal hair are normally not found. It is often associated with hyperandrogenemia and/or polycystic ovary syndrome (PCOS), but the existence of uncommom hirsutism forms that are not related to altered androgen plasma levels lead also to the definition of - idiopathic hirsutism. Although the pathophysiology of hirsutism has been linked to increasing 5-alpha reductase (SRD5A) activity and to an alteration of the androgen receptor (AR) transcriptional machinery, many aspects remain unclear. In particular, the relationships between androgens and local factors are poorly understood. In the present paper, we selected for a genital skin biopsy, 8 women affected with severe hirsutism (Ferriman-Gallway score greater than 25) but with normal plasma androgen levels, with the exception of slightly higher serum 3alpha-diol-glucuronide levels, and 6 healthy controls and analyzed their androgen- and insulin-specific transcriptional profile using a specific custom low density microarray (AndroChip 2, GPL9164). We identified the over-expression of the Son of Sevenless-1 (SOS1) gene in all of the hirsute skin fibroblast primary cell cultures compared to control healthy women. Since SOS1 is a guanine nucleotide exchange factor that couples receptor tyrosine kinases to the RAS signaling pathway that controls cell proliferation and differentiation, we further analyzed SOS1 expression, protein level and RAS signaling activation pathway in an in vitro model (NHDF, normal human dermal fibroblast cell line). NHDF treated for 24 h with different concentrations of DHT and T showed an increase in SOS1 levels (both mRNA and protein) and also an activation of the RAS pathway. Our in vivo and in vitro data represent a novel preliminary observation that factors activating SOS1 could act as local proliferative modulators linked to the androgen pathway in the pilosebaceous unit. SOS1 over-expression may play a role in the regulation of the RAS/mitogen-activated protein kinase pathway in the skin, in the hair follicle proliferation and cell cycle, suggesting new perspectives in understanding the pathogenesis of idiopathic hirsutism.

Abstract
Alveolar type II pneumocytes (ATII cells) are considered putative alveolar stem cells. Since no treatment is available to repair damaged epithelium and prevent lung fibrosis, novel approaches to induce regeneration of injured alveolar epithelium are desired. The objective of this study was to assess both the capacity of human embryonic stem cells (HUES-3) to differentiate in vitro into ATII cells and the ability of committed HUES-3 cells (HUES-3-ATII cells) to recover in vivo a pulmonary fibrosis model obtained by silica-induced damage. In vitro differentiated HUES-3-ATII cells displayed an alveolar phenotype characterised by multi-lamellar body and tight junction formation, by the expression of specific markers such as surfactant protein (SP)-B, SP-C and zonula occludens (ZO)-1 and the activity of cystic fibrosis transmembrane conductance regulator-mediated chloride ion transport. After transplantation of HUES-3-ATII cells into silica-damaged mice, histological and biomolecular analyses revealed a significant reduction of inflammation and fibrosis markers along with lung function improvement, weight recovery and increased survival. The persistence of human SP-C, human nuclear antigen and human DNA in the engrafted lungs indicates that differentiated cells remained engrafted up to 10 weeks. In conclusion, cell therapy using HUES-3 cells may be considered a promising approach to lung injury repair.
