Abstract

Prophylactic low molecular weight heparin (pLMWH) is currently recommended in COVID-19 to reduce the risk of coagulopathy. The aim of this study was to evaluate whether the antinflammatory effects of pLMWH could translate in lower rate of clinical progression in patients with COVID-19 pneumonia. Patients admitted to a COVID-hospital in Rome with SARS-CoV-2 infection and mild/moderate pneumonia were retrospectively evaluated. The primary endpoint was the time from hospital admission to orotracheal intubation/death (OTI/death). A total of 449 patients were included: 39% female, median age 63 (IQR, 50–77) years. The estimated probability of OTI/death for patients receiving pLMWH was: 9.5% (95% CI 3.2–26.4) by day 20 in those not receiving pLMWH vs. 10.4% (6.7–15.9) in those exposed to pLMWH; p-value = 0.144. This risk associated with the use of pLMWH appeared to vary by PaO2/FiO2 ratio: aHR 1.40 (95% CI 0.51–3.79) for patients with an admission PaO2/FiO2 ≤ 300 mmHg and 0.27 (0.03–2.18) for those with PaO2/FiO2 > 300 mmHg; p-value at interaction test 0.16. pLMWH does not seem to reduce the risk of OTI/death mild/moderate COVID-19 pneumonia, especially when respiratory function had already significantly deteriorated. Data from clinical trials comparing the effect of prophylactic vs. therapeutic dosage of LMWH at various stages of COVID-19 disease are needed.

Abstract

Background: Coronavirus disease 2019 (COVID-19), the disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that originated in China in December 2019, was recently recognized as pandemic threat by the World Health Organization, with the potential of rapidly overloading health care systems and causing substantial mortality worldwide (www.who.int/dg/speeches/detail/who-director-general -s-opening-remarks-at-the-media-briefing-on-covid-19 —11-march -2020). Human-to-human transmission occurs mainly through respiratory droplets, but other routes are under investigation, because SARS-CoV-2 has been detected in several body fluids (1). So far, few data are available on ocular samples from patients with COVID-19, although conjunctivitis has been occasionally reported among COVID-19 symptoms, similar to infections caused by other human coronaviruses (2, 3). During the SARS epidemic, eye exposure to infectious fluids was associated with an increased risk for SARS-CoV transmission to health care workers (3, 4). Although SARS-CoV RNA was occasionally found in ocular specimens during the early phase of illness, its infectivity is unknown (2, 3). With regard to COVID-19, unprotected ocular exposure was thought to be responsible for infections that occurred in the Wuhan Fever Clinic in January 2020 (3, 4); in addition, SARS-CoV-2 RNA was detected in conjunctival secretions collected from the only patient with conjunctivitis out of 30 patients with COVID-19 from a hospital in China (5). However, further studies are needed to evaluate the infectious potential of the SARS-CoV-2 RNA detected in the ocular specimens and to determine whether transmission may occur through ocular secretions (3, 4). Objective: To present the early detection of infectious SARS-CoV-2 in ocular fluids from a patient with the first confirmed case of COVID-19 in Italy, who had been hospitalized at the National Institute for Infectious Diseases “L. Spallanzani” (INMI) in Rome. Methods and Findings: The patient, a 65-year-old woman, travelled from Wuhan, China, to Italy on 23 January 2020 and was admitted on 29 January 2020, 1 day after symptom onset. At admission to the high isolation unit at INMI, she presented with nonproductive cough, sore throat, coryza, and bilateral conjunctivitis. She had no fever until day 4, when fever (38 °C), nausea, and vomiting began. Infection with SARS-CoV-2 was confirmed by performing real-time reverse transcription polymerase chain reaction (RT-PCR) assay on sputum samples (cycle threshold value [Ct], 16.1) on the admission day, followed by viral M gene sequencing (GenBank accession number MT008022), and virus isolation on Vero E6 cell line (2019-nCoV/Italy-INMI1). The full genome sequence was obtained from either clinical sample or culture isolate (GISAID accession numbers EPI_ISL_410545 and EPI_ISL_410546). At admission, no other respiratory infections were detected (QIAstat-Dx Respiratory Panel; Qiagen).

Abstract

In the last months, many studies have clearly described several mechanisms of SARS-CoV-2 infection at cell and tissue level, but the mechanisms of interaction between host and SARS-CoV-2, determining the grade of COVID-19 severity, are still unknown. We provide a network analysis on protein–protein interactions (PPI) between viral and host proteins to better identify host biological responses, induced by both whole proteome of SARS-CoV-2 and specific viral proteins. A host-virus interactome was inferred, applying an explorative algorithm (Random Walk with Restart, RWR) triggered by 28 proteins of SARS-CoV-2. The analysis of PPI allowed to estimate the distribution of SARS-CoV-2 proteins in the host cell. Interactome built around one single viral protein allowed to define a different response, underlining as ORF8 and ORF3a modulated cardiovascular diseases and pro-inflammatory pathways, respectively. Finally, the network-based approach highlighted a possible direct action of ORF3a and NS7b to enhancing Bradykinin Storm. This network-based representation of SARS-CoV-2 infection could be a framework for pathogenic evaluation of specific clinical outcomes. We identified possible host responses induced by specific proteins of SARS-CoV-2, underlining the important role of specific viral accessory proteins in pathogenic phenotypes of severe COVID-19 patients.

Abstract

Background Detailed temporal analyses of complete (full) blood count (CBC) parameters, their evolution and relationship to patient age, gender, co-morbidities and management outcomes in survivors and non-survivors with COVID-19 disease, could identify prognostic clinical biomarkers. Methods From 29 January 2020 until 28 March 2020, we performed a longitudinal cohort study of COVID-19 inpatients at the Italian National Institute for Infectious Diseases, Rome, Italy. 9 CBC parameters were studied as continuous variables [neutrophils, lymphocytes, monocytes, platelets, mean platelet volume, red blood cell count, haemoglobin concentration, mean red blood cell volume and red blood cell distribution width (RDW %)]. Model-based punctual estimates, as average of all patients' values, and differences between survivors and non-survivors, overall, and by co-morbidities, at specific times after symptoms, with relative 95% CI and P-values, were obtained by marginal prediction and ANOVA- style joint tests. All analyses were carried out by STATA 15 statistical package. Main findings 379 COVID-19 patients [273 (72% were male; mean age was 61.67 (SD 15.60)] were enrolled and 1,805 measures per parameter were analysed. Neutrophils' counts were on average significantly higher in non-survivors than in survivors (P<0.001) and lymphocytes were on average higher in survivors (P<0.001). These differences were time dependent. Average platelets' counts (P<0.001) and median platelets' volume (P<0.001) were significantly different in survivors and non-survivors. The differences were time dependent and consistent with acute inflammation followed either by recovery or by death. Anaemia with anisocytosis was observed in the later phase of COVID-19 disease in non-survivors only. Mortality was significantly higher in patients with diabetes (OR = 3.28; 95%CI 1.51-7.13; p = 0.005), obesity (OR = 3.89; 95%CI 1.51-10.04; p = 0.010), chronic renal failure (OR = 9.23; 95%CI 3.49-24.36; p = 0.

Abstract

OBJECTIVES: To evaluate the effectiveness of a prevention programme against the vertical transmission of HIV in a resource-limited setting and to investigate variables associated with compliance. PATIENTS AND METHODS: The Kento-Mwana project (2005-2008) provided counselling, serological and biomolecular testing and prophylaxis/therapy to HIV-positive pregnant women and their children attending four antenatal clinics in Pointe Noire, Republic of Congo. Expected and actual rates of vertical transmission of HIV were compared. Univariate and multivariate analyses were performed in order to identify variables associated with non-compliance. RESULTS: The observed transmission rate in the group who completed follow-up was 5/290 (1.7%, 95% CI 0.6%-4.1%). The overall estimated transmission rate in the target population, computed taking into account the expected vertical transmission of HIV among drop-outs, was 67-115/638 (10.5%-18.0%). A comparison between this rate and the expected transmission rate in the absence of intervention (25%-40%) showed that the programme was able to prevent approximately 50% of vertical transmissions. Older age (OR 0.33, 95% CI 0.16-0.66, P = 0.002), telephone availability (OR 0.42, 95% CI 0.24-0.72, P = 0.002) and occupation (OR 0.57, 95% CI 0.29-1.10, P = 0.092) were associated with better compliance. CONCLUSIONS: Despite the vast majority of women accepting counselling and testing, many of them refused prophylaxis or dropped out, thus reducing the effectiveness of the intervention from an ideal 2% to a still important but less impressive median transmission rate of 15% (range 10.5%-18%). Promoting participation and compliance, rather than increasing the potency of antiretroviral regimens, is crucial for preventing the vertical transmission of HIV in Africa

Abstract

Left ventricular dysfunction (LVD) in type 2 diabetes mellitus (DM) (DYDA) study is a prospective investigation enrolling 960 with DM without overt cardiac disease. At baseline, a high prevalence of LVD was detected by analysing midwall shortening. We report here the incidence of clinical events in DYDA patients after 2-year follow-up and the frequency of LVD detected at baseline and 2-year evaluation. METHODS: Systolic LVD was defined as midwall shortening ≤15%, diastolic LVD as any condition different from "normal diastolic function" identified as E/A ratio on Doppler mitral flow between 0.75 and 1.5 and deceleration time of E wave >140 ms. Major outcome was a composite of major events, including all-causes death and hospital admissions. RESULTS: During the study period, any systolic/diastolic LVD was found in 616 of 699 patients (88.1%) in whom LVD function could be measured at baseline or at 2 years. Older age and high HbA1c predicted the occurrence of LVD. During the follow-up 15 patients died (1.6%), 3 for cardiovascular causes, 139 were hospitalized (14.5%, 43 of them for cardiovascular causes, 20 for a new cancer). CONCLUSIONS: During a 2-year follow-up any LVD is detectable in a large majority of patients with DM without overt cardiac disease. Older age and higher HbA1c predict LVD. All-cause death or hospitalization occurred in 15% of patients, cardiovascular cause was uncommon. Independent predictors of events were older age, pathologic lipid profile, high HbA1c, claudicatio and repaglinide therapy. Echo-assessed LVD at baseline was not prognosticator of events.

Abstract

Individuals with diabetes mellitus (DM) have a higher risk to develop heart failure. Clinical guidelines emphasize the importance of early diagnosis of left ventricular dysfunction (LVD) and preventive interventions in these patients. In this study we assessed the prevalence of LVD, systolic or diastolic, in DM patients without known cardiac disease recruited in the 'left ventricular DYsfunction in DiAbetes (DYDA)' study. DESIGN AND METHODS: We performed clinical, ECG, laboratory, and echocardiographic exams in 960 patients (61 ± 8 years, 59% hypertensive) recruited in the DYDA study from 37 Italian diabetes referral centres. ECG and echo exams were read in central facilities. Systolic LVD was defined as ejection fraction ≤ 50% or midwall shortening (MFS) ≤ 15%. Diastolic LVD was identified when transmitral E/A was out of the range of 0.75-1.5 or deceleration time of mitral E wave ≤ 140 msec. RESULTS: Echocardiographic data were obtained in 751 patients (78.2%). Isolated systolic LVD was detected in 22.0% of patients, isolated diastolic LVD in 21.5%, and combined systolic and diastolic LVD in 12.7%. All patients with systolic LVD had MFS ≤ 15%, while only 9% had an ejection fraction ≤ 50%. Higher LV mass, relative wall thickness, prevalence of concentric geometry, and LV hypertrophy characterized the patients with LVD. CONCLUSIONS: LVD is present in more than half of DM patients without clinically detectable cardiac disease and is associated with LV hypertrophy and concentric LV geometry. One-third of patients exhibits systolic LVD detectable at the midwall level.

Abstract

An inappropriately high left ventricular mass (iLVM) may be detected in patients with diabetes mellitus. Several hemodynamic and nonhemodynamic factors stimulating LVM growth may actively operate in these patients. In this study, we assessed prevalence and factors associated with iLVM in patients with diabetes mellitus. METHODS: We analyzed baseline data from 708 patients (61 ± 7 years, 57% treated for hypertension) with type 2 diabetes mellitus without evidence of cardiac disease enrolled in the left ventricular dysfunction in diabetes study. iLVM was diagnosed by Doppler echocardiography as LVM more than 28% of the expected LVM predicted from height, sex and stroke work. RESULTS: iLVM was detected in 166 patients (23%), irrespective of concomitant hypertension. Patients with iLVM were more frequently women, had higher BMI and prevalence of metabolic syndrome, higher serum triglyceride levels and were treated more frequently with metformin and diuretics. In a multivariate model, female sex [odds ratio (OR) 1.502 (95% confidence interval (CI) 1.010-2.231), P = 0.04], higher serum triglyceride levels [OR 1.007 (95% CI 1.003-1.012), P

Abstract

Better knowledge of prevalence and early-stage determinants of subclinical left ventricular dysfunction (LVD) in type 2 diabetes would be useful to design prevention strategies. The objective of the LVD in Diabetes (DYDA) study was to assess these points in patients without established cardiac disease. METHOD: Baseline clinical, ECG, laboratory and echocardiographic data from 751 patients (61 ± 7 years, 59% hypertensive) recruited by 37 Italian diabetes clinics were analysed. Clinical history, life habits, laboratory data (NT-proBNP, HsCRP, HbA1c, serum glucose, lipids and creatinine, liver enzymes, microalbuminuria, glomerular filtrate) and data on microvascular complications and drug therapy were collected. RESULTS: LVD was present in 59.9% of patients. Age (OR 1.05, 95% CI [1.02-1.07]), HbA1c (OR 1.27, 95% CI [1.09-1.49]), triglycerides (OR 1.003, 95% CI [1.001-1.006]), treatment with metformin (OR 1.62, 95% CI [1.09-2.40]) and doxazosine (OR 2.48, 95% CI [1.10-5.55]) were independent predictors of LVD. Glitazones were associated with reduced risk of diastolic dysfunction (OR 0.44, 95% CI [0.22-0.87]) whereas waist circumference and metformin were adversely associated with systolic dysfunction (OR 1.02, 95% CI [1.01-1.04] and 1.57, 95% CI [1.01-2.43], respectively). CONCLUSION: In asymptomatic and fairly controlled diabetic patients, age, worse HbA1c, traits of insulin resistance, such as visceral adiposity and triglycerides or treatment with metformin, and use of doxazosin indicate greater risk of LVD. Glitazones, at this stage, seem to be associated with better diastolic performance.

Abstract

The aim of this study was to evaluate morphological and functional abnormalities by cerebral imaging in a series of systemic lupus erythematosus (SLE) patients with and without overt central nervous system (CNS) manifestations, and to detect possible relationships with clinical parameters and a large panel of autoantibodies, including those reactive against neurotypic and gliotypic antigens. 68 patients with SLE were investigated in a cross-sectional study which included clinical evaluation of symptoms, cerebral magnetic resonance imaging (MRI) and brain single photon emission tomography (SPECT) analysis, electroencephalography (EEG), and serological tests for antibodies directed against nuclear, cytoplasmic neuronal and glial cell-related antigens. The results of this study showed: (1) a significant positive association of (a) anti-glial fibrillary acidic protein (GFAP) serum antibodies with neuropsychiatric (NP) manifestations and (b) antiserin proteinase 3 (anti-PR3/c-ANCA) serum antibodies with pathological cerebral SPECT; (2) the presence of significantly higher values of (a) SLICC organ damage index in patients with abnormal MRI and (b) SLAM activity index in patients with abnormal SPECT; and (3) the association of (a) abnormal MRI with nonactive NP manifestations and (b) combined abnormality of brain SPECT and MRI with the occurrence of overall overt NP manifestations and with those of the organic/major type. Neuropsychiatric manifestations, namely those of the organic/major type, appeared to be significantly associated to the presence of a serum antibody against GFAP, a gliotypic antigen. There was also evidence of an association between SPECT abnormality and the presence of anti-PR3 (c-ANCA). Furthermore, brain imaging by MRI and SPECT applied to SLE patients appears to express CNS involvement significantly related to specific categories of NP manifestations. The abnormalities detected by the two tests seem to be preferentially associated with different activity phases of the NP disorder or of the lupus disease.

Abstract

Forty randomly selected patients with systemic lupus erythematosus (SLE) were studied by clinical and serologic parameters and magnetic resonance imaging (MRI). Abnormal MRI was found in 15/40 patients (37.5%): all 15 cases showed multiple widespread small-sized areas of increased signal in T2 in the white matter; in one of these patients MRI also displayed a large area with a reduced signal in T1 and an increased signal in T2 involving both the white and the gray matter. Among the 15 patients with abnormal MRI, only 7 had neuropsychiatric symptoms. The presence of MRI changes was highest in patients with organic type symptoms and was associated to the highest disease severity scores. A long-term follow up of asymptomatic patients would be useful to establish whether the application of MRI is appropriate for the assessment of CNS involvement in SLE.

Abstract

Celiac disease (CD) diagnosis can be extremely challenging in the case of atypical patterns. In this context, oral signs seem to play a decisive role in arousing suspicion of these forms of the disease. At the same time, the different expressions of the HLA-DQB1*02 allele apparently seem to facilitate the interpretation of signs and highlighted symptoms.The aim of this work was to verify whether it is possible to identify a correlation between the development of oral signs and different DQ2 haplotypes in celiac pediatric patients. 44 celiac patients with amediumage of 9.9 were studied. Oral examinations were performed in order to identify recurrent aphthous stomatitis (RAS) and dental enamel defects (DED). The diagnosis of DED resulted as being related to allele expression (P value = 0.042) while it was impossible to find a similar correlation with RAS. When both oral signs were considered, there was an increase in correlation with HLA-DQB1*02 expression (P value = 0.018). The obtained results identified both the fundamental role that dentists can play in early diagnosis of CD, as well as the possible role of HLA haplotype analysis in arousing suspicion of atypical forms of the disease.

35. Regione sellare: Anatomia, tecnica di studio e patologia

Author

Montaldo, C., Matta, G., Marcia, S., and Tirotto, A.

Abstract

La diagnostica per immagini della regione sellare riconosce come tecniche di elezione la TC e la RM, che consentono una visualizzazione diretta della ghiandola ipofisaria e delle strutture che la circondano. La regione sellare comprende infatti l'ipofisi e le strutture parasellari, rappresentate dal chiasma ottico, dal tuber cinereum, dai corpi mamillari, dal poligono di Willis, dalle cisterne soprasellari e dai seni cavernosi. Lo studio mediante TC viene eseguito con tecnica “convenzionale” oppure con tecnica “TC Dinamica”. Lo studio mediante RM viene eseguito prevalentemente mediante “S.E.” ma anche con tecnica “G.E. 3D” e con tecniche di “Dinamiche RM” (Fast S.E. e G.E.). Vengono successivamente esaminate le più comuni patologie interessanti la regione sellare nei loro aspetti clinico-patologici, esaminando le loro principali caratteristiche di imaging.

Abstract

SARS-CoV-2 serum neutralization assay represents the gold standard for assessing antibody-mediated protection in naturally infected and vaccinated individuals. In the present study, 662 serum samples collected from February 2020 to January 2021 from acute and convalescent COVID-19 patients were tested to determine neutralizing antibody (NAb) titers using a microneutralization test (MNT) for live SARS-CoV-2. Moreover, anti-SARS-CoV-2 IgG, IgA, and IgM directed against different viral antigens were measured by high-throughput automated platforms. We observed higher levels of NAbs in elderly (&gt, 60 years old) individuals and in patients presenting acute respiratory distress syndrome. SARS-CoV-2 NAbs develop as soon as five days from symptom onset and, despite a decline after the second month, persist for over 11 months, showing variable dynamics. Through correlation and receiver operating characteristic (ROC) curve analysis, we set up a testing algorithm, suitable for the laboratory workload, by establishing an optimal cutoff value of anti-SARS-CoV-2 IgG for convalescent plasma donors to exclude from MNT samples foreseen to have low/negative NAb titers and ineligible for plasma donation. Overall, MNT, although cumbersome and not suitable for routine testing of large sample sizes, remains the reference tool for the assessment of antibody-mediated immunity after SARS-CoV-2 infection. Smart testing algorithms may optimize the laboratory workflow to monitor antibody-mediated protection in COVID-19 patients, plasma donors, and vaccinated individuals.

Abstract

Abstract Introduction The aim of this case report is to show how an oral condition, such as atrophic glossitis, can be the only clinical sign that allows an early diagnosis of celiac disease. Case presentation Atrophic glossitis was detected by a dentist during a first routine examination of the oral cavity of a 17-year-old Sardinian young woman and then differential diagnosis was carried out to identify the etiology of her tongue condition. Considering the high prevalence of celiac disease in the patient’s birth area, the clinician took a blood sample to search for vitamin deficiency and immunological anomalies typically linked to celiac disease. Positive blood sample results allowed the patient to be referred to a gastroenterologist in order to perform a small intestine biopsy. The biopsy showed a strong atrophy of the intestinal villus so that it was possible to make a sure diagnosis of celiac disease. After five months on a gluten-free diet, the oral clinician was not able to find any signs of atrophic glossitis. Conclusions Two important conclusions can be reached from this case report; first, the fundamental role played by the oral condition alone in finding and highlighting atypical forms of celiac disease and second, the importance of investigating systemic anomalies, in cases where there is a tongue condition such as atrophic glossitis and when it is impossible to identify local causes.

Abstract

Abstract Background The aim of our study is to describe a fast molecular method, able to distinguish and quantize the two different genotypes (652 and JP2) of an important periodontal pathogen: Actinobacillus actinomycetemcomitans. The two genotypes show differences in the expression of an important pathogenic factor: the leukotoxin (ltx). In order to evidence this, we performed a real time PCR procedure on the ltx operon, able to recognize Aa clinical isolates with different leukotoxic potentials. Methods The specificity of the method was confirmed in subgingival plaque and saliva specimens collected from eighty-one Italian (Sardinian) subjects with a mean age of 43.9, fifty five (68 %) of whom had various clinical forms of periodontal disease. Results This procedure showed a good sensitivity and a high linear dynamic range of quantization (107-102 cells/ml) for all genotypes and a good correlation factor (R2 = 0.97–0.98). Compared with traditional cultural methods, this real time PCR procedure is more sensitive; in fact in two subgingival plaque and two positive saliva specimens Aa was only detected with the molecular method. Conclusion A low number of Sardinian patients was found positive for Aa infections in the oral cavity, (just 10 positive periodontal cases out of 81 and two of these were also saliva positive). The highly leukotoxic JP2 strain was the most representative (60 % of the positive specimens); the samples from periodontal pockets and from saliva showed some ltx genotype for the same patient. Our experience suggests that this approach is suitable for a rapid and complete laboratory diagnosis for Aa infection.

Abstract

Background Omics data, driven by rapid advances in laboratory techniques, have been generated very quickly during the COVID-19 pandemic. Our aim is to use omics data to highlight the involvement of specific pathways, as well as that of cell types and organs, in the pathophysiology of COVID-19, and to highlight their links with clinical phenotypes of SARS-CoV-2 infection. Methods The analysis was based on the domain model, where for domain it is intended a conceptual repository, useful to summarize multiple biological pathways involved at different levels. The relevant domains considered in the analysis were: virus, pathways and phenotypes. An interdisciplinary expert working group was defined for each domain, to carry out an independent literature scoping review. Results The analysis revealed that dysregulated pathways of innate immune responses, (i.e., complement activation, inflammatory responses, neutrophil activation and degranulation, platelet degranulation) can affect COVID-19 progression and outcomes. These results are consistent with several clinical studies. Conclusions Multi-omics approach may help to further investigate unknown aspects of the disease. However, the disease mechanisms are too complex to be explained by a single molecular signature and it is necessary to consider an integrated approach to identify hallmarks of severity.

Abstract

Background Few data about predictors and outcomes associated with prolonged SARS-CoV-2 RNA shedding (VS) are available. Methods Retrospective study including all patients admitted with COVID-19 in an Italian reference hospital for infectious diseases between March 1 and July 1, 2020. Predictors of viral clearance (VC) and prolonged VS from upper respiratory tract were assessed by Poisson regression and logistic regression analyses. The causal relation between duration of VS and probability of clinical outcomes was evaluated through inverse probability weighted Cox model. Results 536 subjects were included. Median duration of VS from symptoms onset was 18 days (IQR 12-26). The estimated 30-day probability of VC was 70.2% (95%CI:65-75). At multivariable analysis, patients with comorbidities (aIRR = 0.88, p = 0.004), lymphopenia at hospital admission (aIRR = 0.75, p = 0.032) and with moderate/severe respiratory disease (aIRR = 0.42, p 1000 ng/mL at admission (aOR = 1.76, p = 0.035) independently predicted prolonged VS.

Abstract

Hepatitis C virus (HCV)-induced iron overload has been shown to promote liver fibrosis, steatosis, and hepatocellular carcinoma. The zonal-restricted histological distribution of pathological iron deposits has hampered the attempt to perform large-scale in vivo molecular investigations on the comorbidity between iron and HCV. Diagnostic and prognostic markers are not yet available to assess iron overload-induced liver fibrogenesis and progression in HCV infections. Here, by means of Spike-in SILAC proteomic approach, we first unveiled a specific membrane protein expression signature of HCV cell cultures in the presence of iron overload. Computational analysis of proteomic dataset highlighted the hepatocytic vitronectin expression as the most promising specific biomarker for iron-associated fibrogenesis in HCV infections. Next, the robustness of our in vitro findings was challenged in human liver biopsies by immunohistochemistry and yielded two major results: (i) hepatocytic vitronectin expression is associated to liver fibrogenesis in HCV-infected patients with iron overload; (ii) hepatic vitronectin expression was found to discriminate also the transition between mild to moderate fibrosis in HCV-infected patients without iron overload. © 2014 WILEY-VCH Verlag GmbH & Co.
