Full textThe development of high-throughput technologies, especially Next Generation Sequencing, has triggered considerable advances in tumor understanding and molecular classification. Patient subgroups for a same tumor have been defined and characterized. Those subgroups are typically associated with a particular prognosis or eligible to a specific targeted therapy. These progresses paved the way towards personalized medicine.The understanding of the contribution of the tumor microenvironment (TME) to disease aggressiveness, progression, and therapy resistance is another revolution in cancer biology and patient care. The contribution of the aforementioned high-throughput technologies was essential. At the era of immunotherapy, the sub-classification of tumors based on their TME composition identified patient subgroups correlated to survival and to their response to this particular class of drugs. Despite a formidable community effort, the molecular and immunological classification of tumors has not been completed for every cancer, some rare and aggressive entities still require thorough characterization. Moreover, most TME studies have focused on the cellular composition and they neglected the mapping of the intercellular communications networks occurring in neoplasms. The advent of single-cell technologies is filling this gap, but with a strong focus on the most frequent cancers.In my thesis, I have both deployed advanced data integration methods and a novel approach to infer ligand-receptor networks relied on a database (LRdb), which is developed by the Colinge Lab, to characterize the TME of two rare tumors, Salivary Duct Carcinoma (SDC) and Primary Central Nervous System Diffuse Large B-Cell Lymphoma (PCNSL). I have combined classical – yet advanced – bioinformatic and multivariate statistics methods integrating bulk transcriptomics and proteomics data, including fresh and TCGA data. Those computational techniques were supplemented with immunofluorescence and immunohistochemistry coupled with digital imaging to obtain experimental validations. To accommodate limited patient cohorts, I have searched for highly coherent messages at all the levels of my analyses. I also devoted important efforts relating our findings with the literature to put them in a clinical perspective. In particular, our approach revealed TME groups of tumors with particular prognosis, immune evasion and therapy resistance mechanisms, several clinical biomarkers, and new therapeutic perspectives

Full textA posteriori use of medical data accumulated by practitioners represents a major challenge for clinical research as well as for personalized patient follow-up. However, health professionals lack the appropriate tools to easily explore, understand and manipulate their data. To solve this, we propose an algorithm to structure elements by similarity and representativeness. This method allows individuals in a dataset to be grouped around representative and generic members who are able to subsume the elements and summarize the data. This approach processes each dimension individually before aggregating the results and is adapted to high-dimensional data and also offers transparent, interpretable and explainable results. The results we obtain are suitable for exploratory analysis and reasoning by analogy: the structure is similar to the organization of knowledge and decision-making process used by experts. We then propose an anomaly detection algorithm that allows complex and high-dimensional anomalies to be detected by analyzing two-dimensional projections. This approach also provides interpretable results. We evaluate these two algorithms on real and simulated high-dimensional data with up to thousands of dimensions. We analyze the properties of graphs resulting from the structuring of elements. We then describe a medical data pre-processing tool and a web application for physicians. Through this intuitive tool, we propose a visual structure of the elements to ease the exploration. This decision support prototype assists medical diagnosis by allowing the physician to navigate through the data and explore similar patients. It can also be used to test clinical hypotheses on a cohort of patients

Full textThe digitalization of healthcare is on and multiple e-health projects are unceasingly coming up. In the rare diseases context, a field that has become a public health policy priority in France, e-health could be a solution to improve rare diseases epidemiology and to propose a better care for patients. The national data bank for rare diseases (BNDMR) offers the centralization of these epidemiological studies conduction for all rare diseases and all affected patients followed in the French healthcare system. The BNDMR must grow in a dense and heterogeneous digital landscape. Developing the BNDMR interoperability is the objective of this thesis’ work. How to identify patients, including fetuses? How to federate patients’ identities to avoid duplicates creation? How to link patients’ data to allow studies’ conduction? In response to these questions, we propose a universal method for patients’ identification that meets the requirements of health data protection. Which data should be collected in the national data bank? How to improve and facilitate the development of interoperability between these data and those from the wide range of the existing systems? In response to these questions, we first propose the collection of a standardized minimum data set for all rare diseases. The implementation of international standards provides a first step toward interoperability. We then propose to move towards the discovery of mappings between heterogeneous data sources. Minimizing human intervention by adopting automated alignment techniques and making these alignments’ results reliable and exploitable were the main motivations of our proposal

Full textThe repurposing of clinical data for research has become widespread with the development of clinical data warehouses. These data warehouses are modeled to integrate and explore structured data related to thesauri. These data come mainly from machine (biology, genetics, cardiology, etc.) but also from manual data input forms. The production of care is also largely providing textual data from hospital reports (hospitalization, surgery, imaging, anatomopathologic etc.), free text areas in electronic forms. This mass of data, little used by conventional warehouses, is an indispensable source of information in the context of rare diseases. Indeed, the free text makes it possible to describe the clinical picture of a patient with more precision and expressing the absence of signs and uncertainty. Particularly for patients still undiagnosed, the doctor describes the patient's medical history outside any nosological framework. This wealth of information makes clinical text a valuable source for translational research. However, this requires appropriate algorithms and tools to enable optimized re-use by doctors and researchers. We present in this thesis the data warehouse centered on the clinical document, which we have modeled, implemented and evaluated. In three cases of use for translational research in the context of rare diseases, we attempted to address the problems inherent in textual data: (i) recruitment of patients through a search engine adapted to textual (data negation and family history detection), (ii) automated phenotyping from textual data, and (iii) diagnosis by similarity between patients based on phenotyping. We were able to evaluate these methods on the data warehouse of Necker-Enfants Malades created and fed during this thesis, integrating about 490,000 patients and 4 million reports. These methods and algorithms were integrated into the software Dr Warehouse developed during the thesis and distributed in Open source since September 2017

Full textIn the last years, the advent of exome sequencing (ES) in diagnosis and in research led to the identification of the genetic bases of many Mendelian disorders, allowing many diagnostic wavering cases to be solved. Nevertheless, ES data analysis only leads to the identification of pathogenic or likely pathogenic variants in 30 to 45 % of the undiagnosed cases. Indeed, some limits exist, both at clinical, molecular and bioinformatic levels. The constant evolution of the clinical knowledge, of the number of genes involved in human diseases, and of the clinical-biological correlations, has a significant impact on data analysis, leading to a progressive improvement in diagnostic research. Limits of the current technologies, especially not covered regions, exist, but have been significantly reduced in the recent years. Although genome sequencing will solve some undiagnosed cases, especially in case of non-coding or structural variants, there is still a lot of information to be extracted and analyzed from ES data. Finally, beyond SNV and CNV analyzes, other genetic events can be involved in rare disorders, requiring a bioinformatic development to optimize results.The aim of the project was therefore to improve bioinformatic approaches of ES data analysis in order to identify new molecular mechanisms involved in rare genetic disorders and reduce diagnostic wavering.Several strategies were established. The first one consisted in reanalysing ES data from 80 undiagnosed patients, who were sequenced by the Laboratoire CERBA (CIFRE thesis). It led to the identification of 2 new candidate genes involved in ID, especially OTUD7A gene (article 1). The second strategy was the development of a bioinformatic pipeline in order to extract mitochondrial DNA data from ES data. The mitochondrial genome is not targeted by exome capture kits but can be extracted from off-target data, giving the opportunity to analyze it from preexisting ES data. From the GAD exomes cohort of undiagnosed patients, 2 causal variations were identified in 2 individuals out of 928, affected with neuro-developmental disorder. It thus solved the diagnostic wavering in 0.2 % of patients without diagnosis (article 2). The third strategy consisted in the development of a bioinformatic pipeline to identify mobile elements insertion within ES data, with the expectation that about 0.03 % of the pathogenic variants originate from de novo mobile element insertion. From the GAD exomes cohort of 3322 undiagnosed patients, this step led to the identification of two Alu element insertions in FERMT1 and GRIN2B gene exons (article 3, in process).This PhD permitted to push out some ES limits. Other perspectives exist, and are explored by the GAD team, in connection with the European Solve-RD project

Full textTitle : Genome-wide exploration of congenital anomalies of rare causesKey words : congenital anomalies, exome sequencing, data-sharing, reverse phenotypingCongenital anomalies are a group of diseases that are both clinically and molecularly heterogeneous. They include more than 3,000 monogenic diseases, but only a third of them have a known molecular cause. Although advances in sequencing techniques have identified hundreds of new genes in recent years, many patients remain undiagnosed. The vast genetic heterogeneity of these conditions challenges the conventional diagnostic approach that typically includes clinical expertise, a pan-genomic microarray study and/or targeted analysis of known genes and, recently, exome sequencing targeting the genes already associated with human disease. Until genome sequencing becomes more affordable and the interpretation of its data for diagnostic use is better perceived, we have chosen to explore new strategies to optimize the identification of new molecular bases through exome sequencing.The first article aimed to demonstrate the feasibility and effectiveness of annual reanalysis of negative exome sequencing data in a diagnostic setting. Patients eligible for the study had developmental anomalies, but no molecular cause was established after a standard diagnostic procedure including DNA chromosome analysis and diagnostic exome analysis. This first study yielded a significant number of additional diagnoses, but also identified candidate variants for which we used international data-sharing and reverse phenotyping to establish cohorts of genotypic and/or phenotypic replication and genotype-phenotype correlations. These strategies allowed us to meet the ACMG criteria necessary to establish the pathogenicity of these variants.With this experience, and because we wished to go further in identifying new molecular bases for our patients, we continued the reanalysis project within a research framework. This was the focus of the second article of this thesis. The reanalysis project led to the identification of 17 new genes associated with congenital anomalies. Data-sharing has led to the development of numerous international collaborations and functional studies carried out by specialized teams.The third article illustrated the application of these tools in a syndromic form of ultra-rare intellectual disability. Following a considerable collaborative effort, we were able to accurately describe the phenotype of 25 unreported patients in the literature with pathogenic variants in the TBR1 gene, a candidate gene in autism spectrum disorders associated to intellectual disability.These various studies demonstrate how innovative strategies can be effective for identifying new molecular bases in patients with congenital anomalies. These strategies include exome data reanalysis, reverse phenotyping, and international data-sharing. For patients and their families, knowing the molecular basis of the disease makes it possible to understand the origin of the condition and to put an end to diagnostic wandering. In addition, they are able to learn more about the prognosis and developmental progression, and they can obtain appropriate care management. This information is also essential for reliable genetic counseling, and may offer the possibility of prenatal or even pre-implantation diagnosis. These new diagnoses also give geneticists a chance to understand new physiopathological processes, to develop new diagnostic tests and even to discover new therapeutic targets

Full textOver the last decade, biomedical research and medical practice have been revolutionized by the post-genomic era and the emergence of Big Data in biology. The field of rare diseases, are characterized by scarcity from the patient to the domain knowledge. Nevertheless, rare diseases represent a real interest as the fundamental knowledge accumulated as well as the developed therapeutic solutions can also benefit to common underlying disorders. This thesis focuses on the development of new bioinformatics solutions, integrating Big Data and Big Data associated approaches to improve the study of rare diseases. In particular, my work resulted in (i) the creation of PubAthena, a tool for the recommendation of relevant literature updates, (ii) the development of a tool for the analysis of exome datasets, VarScrut, which combines multi-level knowledge to improve the resolution rate

Full textBayesian approach augments the information provided by the trial itself by incorporating external information into the trial analysis. In addition, this approach allows the results to be expressed in terms of probability of some treatment effect, which is more informative and interpretable than a p-value and a confidence interval. In addition, the frequent reduction of an analysis to a binary interpretation of the results (significant versus non-significant) is particularly harmful in rare diseases.In this context, the objective of my work was to explore the feasibility, constraints and contribution of the Bayesian approach in clinical trials in rare cancers with a primary censored endpoint. A review of the literature confirmed that the implementation of Bayesian methods is still limited in the analysis of clinical trials with a censored endpoint.In the second part of our work, we developed a Bayesian design, integrating historical data in the setting of a real clinical trial with a survival endpoint in a rare disease (osteosarcoma). The prior incorporated individual historical data on the control arm and aggregate historical data on the relative treatment effect. Through a large simulation study, we evaluated the operating characteristics of the proposed design and calibrated the model while exploring the issue of commensurability between historical and current data. Finally, the re-analysis of three clinical trials allowed us to illustrate the contribution of Bayesian approach to the expression of the results, and how this approach enriches the frequentist analysis of a trial

Full textThe molten alloy solid-liquid method containing lithium has recently enabled the synthesis of several bulk graphite intercalation compounds (GICs) in graphite-lithium-alkaline earth metal systems. As part of this thesis, this synthesis method was extended to graphite-lithium-lanthanide systems, with an additional difficulty which is the lack of knowledge of lithium-lanthanide binary phase diagrams whose data are crucial for determining the temperature range and chemical composition of alloys that may lead to GICs.The immersion of pyrographite platelets in some europium-lithium alloys wisely chosen led to a binary EuC6 compound as well as a graphite-lithium-europium first stage ternary compound.Kinetics study of EuC6 compound was followed by ex situ X-ray diffraction in order to understand the different reaction steps and identify intermediate phases leading to the thermodynamically stable final compound. This mechanism revealed a reaction process more "cooperative" than that leading to CaC6 binary compound and was described by a succession of steps that contribute to the bulk insertion of europium.The elementary composition of the ternary compound was determined by ions beam analysis allowing the simultaneous quantification of the three elements lithium, carbon and europium. The refinement of these analyses led to the chemical formula Li0,25Eu1,95C6 for the ternary compound. EuC6 has also been studied by nuclear microprobe analysis, and especially the C/Eu atomic ratio equal to 6 has been confirmed.Structural studies have been undertaken for binary and ternary compounds. On one hand, it was possible to fully resolve the three-dimensional structure of the binary EuC6, which crystallizes in a hexagonal unit cell with P63/mmc space group. On the other hand, the c axis stacking sequence of the poly-layered intercalated sheet of the ternary compound was modeled by combining structural data with information from the ions beam analysis. The graphite intercalation compounds are low-dimensional solids that are ideal for the study of structure-properties relations. Thus in graphite-lithium-calcium system, superconducting character has been studied for CaC6 and Li3Ca2C6 compounds by muons spin spectroscopy ([mu]SR). For the graphite-lithium-europium system, previous magnetic measurements have been continued and supplemented by [mu]SR analysis (for Li0,25Eu1,95C6 and EuC6) and by low temperature 151Eu Mössbauer spectroscopy (for Li0,25Eu1,95C6)
