Electronic reporting of rare endocrine conditions within a clinical network: results from the EuRRECa project.

Objective: The European Registries for Rare Endocrine Conditions (EuRRECa, eurreb.eu) includes an e-reporting registry (e-REC) used to perform surveillance of conditions within the European Reference Network (ERN) for rare endocrine conditions (Endo-ERN). The aim of this study was to report the experience of e-REC over the 3.5 years since its launch in 2018. Methods: Electronic reporting capturing new encounters of Endo-ERN conditions was performed monthly through a bespoke platform by clinicians registered to participate in e-REC from July 2018 to December 2021. Results: The number of centres reporting on e-REC increased to a total of 61 centres from 22 countries. A median of 29 (range 11, 45) paediatric and 32 (14, 51) adult centres had reported cases monthly. A total of 9715 and 4243 new cases were reported in adults (age ≥18 years) and children, respectively. In children, sex development conditions comprised 40% of all reported conditions and transgender cases were most frequently reported, comprising 58% of sex development conditions. The median number of sex development cases reported per centre per month was 0.6 (0, 38). Amongst adults, pituitary conditions comprised 44% of reported conditions and pituitary adenomas (69% of cases) were most commonly reported. The median number of pituitary cases reported per centre per month was 4 (0.4, 33). Conclusions: e-REC has gained increasing acceptability over the last 3.5 years for capturing brief information on new encounters of rare conditions and shows wide variations in the rate of presentation of these conditions to centres within a reference network. Significance statement Endocrinology includes a very wide range of rare conditions and their occurrence is often difficult to measure. By using an electronic platform that allowed monthly reporting of new clinical encounters of several rare endocrine conditions within a defined network that consisted of several reference centres in Europe, the EuRRECa project shows that a programme of e-surveillance is feasible and acceptable. The data that have been collected by the e-reporting of rare endocrine conditions (e-REC) can allow the continuous monitoring of rare conditions and may be used for clinical benchmarking, designing new studies or recruiting to clinical trials.

The Communicative-Relational Operating Model of the Italian National Institute of Health for an Effective Telephone Intervention in Public Health, Structured on Basic Counselling Skills.

Introduction: Communication has a crucial role in public health, because it becomes an essential component of prevention; it is also a proactive tool in health promotion. From a planning perspective, it is appropriate to use communication means that can help the bidirectional communication process, such as face-to-face communication and telephone communication. Materials and methods: In relation to this, the Italian National Institute of Health has developed the "Modello Operativo Comunicativo-Relazionale" (the "Communicative-Relational Operating Model"). It is based on the fundamental skills of the counselling, this gives a protocol to the health professionals that is replicable and organized and it allows health professionals to carry out a telephone communication that is efficient with the user through technical-scientific and communication-relational skills. The goal is to answer in a customized way to the various users' health needs. The Operating Model was created by experts of the National AIDS and Sexually Transmitted Infections Helpline of the Operational Unit of Psycho-Socio-Behavioural Research, Communication, Training, of the Infectious Diseases Department. Later, the Operating Model was proposed to the experts of the Helplines in the National Centre on Addictions and Doping and the National Helpline of the National Centre for Rare Diseases in the National Institute of Health that integrated this method into their telephone approach. Results: The Operating Model illustrated above was applied to several helplines of the National Institute of Health as an example of correct scientific information, updated and customized on sexual transmitted infections, addictions and rare diseases. Conclusions: This article aims to illustrate the Operating Model, the theoretical prerequisites that subtend it and its possible application in the different public health structures that use the telephone for a profes-sional relationship with their users.

The Undiagnosed Diseases Network International: Five years and more!

Undiagnosed rare diseases (URDs) account for a significant portion of the overall rare disease burden, depending upon the country. Hence, URDs represent an unmet medical need. A specific challenge posed by the ensemble of the URD patient cohort is the heterogeneity of its composition; the group, indeed, includes very rare, still unidentified conditions as well as clinical variants of recognized rare diseases. Exact disease recognition requires new approaches that cut across national and institutional boundaries, may need the implementation of methods new to diagnostics, and embrace clinical care and research. To address these issues, the Undiagnosed Diseases Network International (UDNI) was established in 2014, with the major aims of providing diagnoses to patients, implementing additional diagnostic tools, and fostering research on novel diseases, their mechanisms, and their pathways. The UDNI involves centres with internationally recognized expertise, and its scientific resources and know-how aim to fill the knowledge gaps that impede diagnosis, in particularly for ultra-rare diseases. Consequently, the UDNI fosters the translation of research into medical practice, aided by active patient involvement. The goals of the UDNI are to work collaboratively and at an international scale to: 1) provide diagnoses for individuals who have conditions that have eluded diagnosis by clinical experts; 2) gain insights into the etiology and pathogenesis of novel diseases; 3) contribute to standards of diagnosing unsolved patients; and 4) share the results of UDNI research in a timely manner and as broadly as possible.

The current landscape of European registries for rare endocrine conditions.

Objective To identify cross-border international registries for rare endocrine conditions that are led from Europe and to understand the extent of engagement with these registries within a network of reference centres (RCs) for rare endocrine conditions. Methods Database search of international registries and a survey of RCs in the European Reference Network for rare endocrine conditions (Endo-ERN) with an overall response rate of 82%. Results Of the 42 conditions with orphacodes currently covered within Endo-ERN, international registries exist for 32 (76%). Of 27 registries identified in the Orphanet and RD-Connect databases, Endo-ERN RCs were aware of 11 (41%). Of 21 registries identified by the RC, RD-Connect and Orphanet did not have a record of 10 (48%). Of the 29 glucose RCs, the awareness and participation rate in an international registry was highest for rare diabetes at 75 and 56% respectively. Of the 37 sex development RCs, the corresponding rates were highest for disorders of sex development at 70 and 52%. Of the 33 adrenal RCs, the rates were highest for adrenocortical tumours at 68 and 43%. Of the 43 pituitary RCs, the rates were highest for pituitary adenomas at 43 and 29%. Of the 31 genetic tumour RCs, the rates were highest for MEN1 at 26 and 9%. For the remaining conditions, awareness and participation in registries was less than 25%. Conclusion Although there is a need to develop new registries for rare endocrine conditions, there is a more immediate need to improve the awareness and participation in existing registries.

Red Flags for early referral of people with symptoms suggestive of narcolepsy: a report from a national multidisciplinary panel.

OBJECTIVE: Narcolepsy is a lifelong disease, manifesting with excessive daytime sleepiness and cataplexy, arising between childhood and young adulthood. The diagnosis is typically made after a long delay that burdens the disease severity. The aim of the project, promoted by the "Associazione Italiana Narcolettici e Ipersonni" is to develop Red Flags to detect symptoms for early referral, targeting non-sleep medicine specialists, general practitioners, and pediatricians. MATERIALS AND METHODS: A multidisciplinary panel, including patients, public institutions, and representatives of national scientific societies of specialties possibly involved in the diagnostic process of suspected narcolepsy, was convened. The project was accomplished in three phases. Phase 1: Sleep experts shaped clinical pictures of narcolepsy in pediatric and adult patients. On the basis of these pictures, Red Flags were drafted. Phase 2: Representatives of the scientific societies and patients filled in a form to identify barriers to the diagnosis of narcolepsy. Phase 3: The panel produced suggestions for the implementation of Red Flags. RESULTS: Red Flags were produced representing three clinical pictures of narcolepsy in pediatric patients ((1) usual sleep symptoms, (2) unusual sleep symptoms, (3) endocrinological signs) and two in adult patients ((1) usual sleep symptoms, (2) unusual sleep symptoms). Inadequate knowledge of symptoms at onset by medical doctors turned out to be the main reported barrier to diagnosis. CONCLUSIONS: This report will hopefully enhance knowledge and awareness of narcolepsy among non-specialists in sleep medicine in order to reduce the diagnostic delay that burdens patients in Italy. Similar initiatives could be promoted across Europe.

Patient Associations: a driving force for Rare Diseases research. Resilience: a driving force for Patient Associations.

Until a few decades ago, Rare Diseases were relatively unknown. Their low prevalence made them invisible to public opinion, and were of little concern to researchers and pharmaceutical industries. Rare disease sufferers and their loved ones had become victims of the disease as their implications were overlooked. Consequently, some of these individuals formed associations and embarked on ways to change this situation of neglect they had found themselves, in finally having their rights recognized. These associations have over time gained important roles in planning public health and biomedical research, especially after the introduction of the Human Genome Project. Their active participation and awareness activities have been crucial in establishing reliable Rare Diseases Registries and related Biobanks, essential tools in fully utilizing the data and the new omics technologies derived from the Human Genome Project in the field of Rare Diseases. The founders and members of these associations have a high degree and considerable ability to face the difficulties of life, while also maintaining a positive attitude and a confident vision, best defined as resilience. Not everyone, and not always, is endowed with a resilience capability. However resilience can be improved or reinforced through appropriate training and intervention programs. This review points out specific programs centered mainly on mindfulness.

Social/economic costs and health-related quality of life in patients with juvenile idiopathic arthritis in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with juvenile idiopathic arthritis (JIA) in Europe. METHODS: We conducted a cross-sectional study of patients with JIA from Germany, Italy, Spain, France, the United Kingdom, Bulgaria, and Sweden. Data on demographic characteristics, healthcare resource utilization, informal care, labor productivity losses, and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D-5L) questionnaire. RESULTS: A total of 162 patients (67 Germany, 34 Sweden, 33 Italy, 23 United Kingdom, 4 France, and 1 Bulgaria) completed the questionnaire. Excluding Bulgarian results, due to small sample size, country-specific annual health care costs ranged from €18,913 to €36,396 (reference year: 2012). Estimated direct healthcare costs ranged from €11,068 to €22,138; direct non-healthcare costs ranged from €7837 to €14,155 and labor productivity losses ranged from €0 to €8715. Costs are also shown to differ between children and adults. The mean EQ-5D index score for JIA patients was estimated at between 0.44 and 0.88, and the mean EQ-5D visual analogue scale score was estimated at between 62 and 79. CONCLUSIONS: JIA patients incur considerable societal costs and experience substantial deterioration in HRQOL in some countries. Compared with previous studies, our results show a remarkable increase in annual healthcare costs for JIA patients. Reasons for the increase are the inclusion of non-professional caregiver costs, a wider use of biologics, and longer hospital stays.

The Italian National External quality assessment program in molecular genetic testing: results of the VII round (2010-2011).

Since 2001 the Istituto Superiore di Sanità established a quality assurance programme for molecular genetic testing that covers four pathologies: Cystic Fibrosis (CF), Beta Thalassemia (BT), Fragile X Syndrome (FX), and Familial Adenomatous Polyposis Coli (APC). Since 2009 this activity is an institutional activity and participation is open to both public and private laboratories. Seven rounds have been performed until now and the eighth is in progress. Laboratories receive 4 DNA samples with mock clinical indications. They analyze the samples using their routine procedures. A panel of assessors review the raw data and the reports; all data are managed through a web utility. In 2010 the number of participants was 43, 17, 15, 5 for CF, BT, FX, APC schemes respectively. Genotyping results were correct in 96%, 98.5%, 100%, and 100% of CF, BT, FX, and APC samples, respectively. Interpretation was correct in 74%, 91%, 88%, and 60% of CF, BT, FX, and APC reports, respectively; however in most of them it was not complete but a referral to genetic counseling was given. Reports were satisfactory in more than 60% of samples in all schemes. This work presents the 2010 results in detail comparing our data with those from other European schemes.

EUROPLAN: a project to support the development of national plans on rare diseases in Europe.

BACKGROUND/AIMS: National Plans for Rare Diseases (RDs) are the common denominator of current public health policy concerns on RDs across the EU. With the aim of a better distribution of the available resources, they conjugate the European objective that aims at ensuring that patients with RDs have access to high-quality care - including diagnostics, treatment and rehabilitation - with the national priorities of selecting specific measures for adoption and implementation. METHODS: The European Project for Rare Diseases National Plans Development (EUROPLAN, www.europlanproject.eu) is cofunded by the EU Commission (DG-SANCO) and is coordinated by the Italian National Center for Rare Diseases of the Istituto Superiore di Sanità (ISS). The EUROPLAN goal is to promote the implementation of National Plans or Strategies to tackle RDs and share relevant experiences within countries, linking national efforts, through a common strategy at a European level. In order to fulfill these objectives, EUROPLAN involved health authorities, clinicians, scientists, the European Organisation for Rare Diseases (EURORDIS), and many other patient groups as associated and collaborating partners from several European countries. RESULTS: The project was launched in 2008 and foresaw 2 implementation phases: phase 1 (2008-2011) to build the consensus definition of operational tools (recommendations and indicators), and the ongoing phase 2 (2012-2015), mainly aimed at capacity building with the proactive involvement of multilevel stakeholders. EUROPLAN is facilitating and accelerating the implementation of National Plans in almost all EU and several non-EU Countries. CONCLUSIONS: EUROPLAN is a European and an international process more than a project, and it could be defined as a 'litmus test' demonstrating how the collaboration between institutions and patients' associations can accelerate the process of awareness and development of policies and actions.

The current situation and needs of rare disease registries in Europe.

BACKGROUND: Registries are considered key instruments for developing rare disease (RD) clinical research, enhancing patient care and health planning, and improving social, economic and quality-of-life outcomes. Indeed, it is usually the case that no single institution, and in many cases no single country, has sufficient data to provide results that can be applied broadly to clinical and translational research. However, the fragmentation and heterogeneity of the registries, which are often the result of spontaneous initiatives, limit the general applicability of their observations. METHODS: An inquiry has been carried out by the EPIRARE, a European Union (EU)-funded project ('Building Consensus and Synergies for the EU Registration of Rare Disease Patients') aiming at paving the way to the creation of a European Platform for RD Registries, by means of an on-line questionnaire among European RD registries on their main activities and needs, the way they deal with methodological, technical and regulatory issues and the way they find resources to carry on their activities. RESULTS: In spite of the heterogeneity of the European registries, some elements of relevance for an action to improve the situation of patient registries in the EU are apparent. The needs more frequently indicated by registry holders were financial support, motivation of data providers, data quality assessment, improvement of communication and visibility, and extension of collaborations. Moreover, the registry holders were in favor of a common EU platform providing services for RD registries. CONCLUSION: It appears that the current situation of the European registries provides the transition towards a more uniform, higher quality and better coordinated approach.

A model for the European platform for rare disease registries.

BACKGROUND: The current situation of rare disease (RD) registries is rather heterogeneous, and new ways to support the registration of RD patients are being sought in the European Union (EU) and the US. The project 'Building Consensus and Synergies for the EU Registration of RD Patients', funded by the EU, aimed to define a model platform for EU RD registries. METHODS: A number of surveys and extensive consultations among registry stakeholders have been carried out to study how the platform can best fulfill their needs. RESULTS: This web-based, multidisease and multipurpose platform is intended to provide a number of functions: a metadata and data repository function supporting the planning of research studies and the production of predefined outputs for the funding organizations and the public, provision of tools and resources of use to registries, promotion of registration and networking among patients and professionals. CONCLUSION: Its main impact is expected to be on data and procedures standardization, on the establishment of new registries, on the sustainability of the smaller ones, and on the registration of those RDs for which a dedicated registry is not sustainable, e.g. ultra-rare diseases or diseases for which there is no special research, clinical or economic interest. It will also impact on the production of sounder information on RD and RD-dedicated health systems, by promoting registry data comparability and quality.

Characterization of HuH6, Hep3B, HepG2 and HLE liver cancer cell lines by WNT/ß - catenin pathway, microRNA expression and protein expression profile.

Somatic mutations in the genes members of WNT/ß-catenin pathway, especially in CTNNB1 codifying for ß-catenin, have been found to play an important role in hepatocarcinogenesis. The purpose of this work is to characterize alterations of the WNT/ß-catenin signalling pathway, and to study the expression pattern of a panel of microRNAs and proteins potentially involved in the pathogenesis of liver cancer. In this respect, the molecular characterization of the most used liver cancer cell lines HuH6, Hep3B, HepG2, and HLE, could represent a useful tool to identify novel molecular markers for hepatic tumour. A significant modulation of FZD7, NLK, RHOU, SOX17, TCF7L2, TLE1, SLC9A3R1 and WNT10A transcripts was observed in all the four liver cancer cell lines. The analysis of selected microRNAs showed that miR-122a, miR-125a and miR-150 could be suitable candidates to discriminate tumoural versus normal human primary hepatocytes. Finally, Grb-2 protein expression resulted to be increased more than two-fold in liver cancer cell lines in comparison to normal human primary hepatocytes. These advances in the knowledge of molecular mechanisms involved in the pathogenesis of liver cancer may provide new potential biomarkers and molecular targets for the diagnosis and therapy.

MicroRNA profiling of multiple osteochondromas: identification of disease-specific and normal cartilage signatures.

Multiple osteochondroma (MO) is a rare skeletal disease characterized by the formation of multiple benign cartilage-capped bone tumors; in 1-5% of patients, a malignant transformation into peripheral chondrosarcoma may occur. This disorder is characterized by a large spectrum of germline mutations scattered along EXT1/EXT2 genes, the presence of a significant percentage of patients without alterations in EXT genes, and a large phenotypic variability. The molecular basis of MO genetic and clinical heterogeneity, including the causes underlying malignant transformation, is currently unknown. This leads to the lack of appropriate diagnostic/prognostic markers as well as of therapeutic options. Recently, specific microRNAs (miRNAs) were reported to be involved in chondrogenesis and inflammatory cartilage diseases. We therefore hypothesized a role for microRNAs in cartilaginous tumors and investigated microRNA expression in osteochondroma and normal cartilage tissues to evaluate whether they could affect osteochondromas onset and/or clinical manifestations. Our results indicate that miRNAs differentially expressed in MO samples may hamper the molecular signaling responsible for normal differentiation of chondrocytes, contributing to pathogenesis and clinical outcome. Although further studies are needed to validate our observations and to identify targets of miRNAs, this is the first study reporting on miRNA expression in growth plate and its comparison with pathological conditions.

Complex multipathways alterations and oxidative stress are associated with Hailey-Hailey disease.

BACKGROUND: Hailey-Hailey disease (HHD) is an autosomal dominant disorder characterized by suprabasal cutaneous cell separation (acantholysis) leading to the development of erosive and oozing skin lesions. While a strong relationship exists between mutations in the gene that encodes the Ca(2+)/Mn(2+)-adenosine triphosphatase ATP2C1 and HHD, we still have little understanding of how these mutations affect manifestations of the disease. OBJECTIVES: This study was designed to determine early signalling events that affect epithelial cell growth and differentiation during HHD development. METHODS: Expression of key regulatory signals important for maintaining skin homeostasis were evaluated by Western blot analysis and by reverse transcriptase-polymerase chain reaction in primary keratinocytes obtained from skin biopsies of patients with HHD. Reactive oxygen species accumulation in primary keratinocytes derived from lesional skin of patients with HHD was assessed by dihydrorhodamine 123 (DHR) assay. RESULTS: HHD-derived keratinocytes showed downregulation of both Notch1 and differential regulation of different p63 isoforms. Itch and p63 are co-expressed in the epidermis and in primary keratinocytes where Itch controls the p63 protein steady-state level. We found that the Itch protein was significantly decreased in HHD-derived keratinocytes whereas the expression of its target, c-Jun, remained unaffected. We also found that HHD-derived keratinocytes undergo oxidative stress, which may explain both Notch1 and Itch downregulation. CONCLUSIONS: Our attempt to explore the molecular mechanism underlying HHD indicates a complex puzzle in which multi-hit combinations of altered signal pathways may explain the wide spectrum of defects in HHD.

The Italian external quality assessment scheme in classical cytogenetics: four years of activity.

BACKGROUND: The Italian external quality assessment scheme in classical cytogenetics was started in 2001 as an activity funded by the National Health System and coordinated by the Italian Public Institute of Health. OBJECTIVES: The aim of our work is to present data from the first 4 years of activity, 2001-2004. METHODS: Italian cytogenetics public laboratories were enrolled on a voluntary basis, and this nationwide program covered prenatal, postnatal and oncological diagnosis. The scheme is annual and retrospective; a panel of experts reviewed the quality of images and reports in order to assess technical, analytical and interpretative performance. RESULTS: Over the 4-year period, the number of participating laboratories increased: from 36 in 2001, 46 in 2002, 49 in 2003 to 51 in 2004. The overall technical performance was satisfactory. Inadequacy or lack of information in reporting was the most frequent analytical inaccuracy identified in all parts of the scheme. However, the percentage of complete reports increased significantly during the period: by 36% in postnatal diagnosis between 2001 and 2004 (p < 0.001) and by 42% in oncological diagnosis between 2002 and 2004 (p = 0.003). CONCLUSIONS: Our experience reveals that participation in external quality assessment programs has significant advantages, helping to standardize and to assure quality in cytogenetic testing.

[Folic acid and congenital malformation: scientific evidence and public health strategies]. / Acido folico e difetti congeniti: evidenze scientifiche e strategie di sanità pubblica.

In Italy at least 3% of babies are born with some congenital malformation. The intake of folic acid (FA) prior to conception and during the early stages of pregnancy plays an important role in preventing neural tube defects, severe anomalies of brain embryogenesis, and other malformations such as cardiac and urinary tract anomalies, oro-facial clefts and limb reduction defects. The Italian Network for Folic Acid Promotion, coordinated by the National Center on Rare Diseases of the Italian National Institute of Health, has elaborated and diffused a recommendation for the periconceptional FA supplementation: "Women of child-bearing age, are recommended to consume 0,4 mg/day of FA, to reduce the risk of congenital defects. The intake of folic acid should start at least one month before the conception and should continue for the first quarter of pregnancy". This paper discusses various strategies in order to promote FA intake during periconceptional period. Food fortification, adopted in several countries such as USA, has raised concerns about the risk of an excessive FA intake which may lead to adverse effect such as tumour promotion. Currently, periconceptional supplementation and healthy dietary habits promotion appear to be the most effective strategies.

Access to and quality of health and social care for rare diseases: patients' and caregivers' experiences.

People suffering from rare diseases, independently of the condition, often experience the same problems in receiving adequate health and social care. It is not clear how these problems differ in severity among different diseases and in different countries and how they change in time. In the framework of the NEPHIRD (Network of Public Health Institutions on Rare Diseases), a European project, funded by DG-SANCO (EU Commission), an effort was made to develop a simple but comprehensive tool to show patients' and/or caregivers' opinions about the quality and accessibility of health and social services. The self-filled questionnaire asks how often patients or caregivers had both negative and positive experiences about the quality and accessibility of health and social services and their opinion on their improvement, on 5-level scales. A pilot survey was carried out in several European Countries among members of Myasthenia Gravis, Neurofibromatosis, Prader Willi and Rett Syndrome volunteers' associations. Descriptive and comparative analyses were performed using Stata and Epi Info 2000. In total, 302 questionnaires were completed in France, Italy, Romania, Spain, Turkey and United Kingdom during 2004-05. In general, respondents thought that health care accessibility was worse than quality, and that social care and legal provisions were worse than health care, with some differences among countries. For all diseases, and for both patients and caregivers, the most frequent reported positive experiences were health professionals' kindness and readiness to help (all medians ranged from 3 to 5). As for the efforts for improvement made by public services in the last three years, the opinions were generally favourable. This study has several limitations. However the assessment tool that has been developed has some innovative and interesting features and may be considered a useful attempt to compare patients' and caregivers' experiences for a range of different diseases, countries and services, with respect to a rare disease programme.
