Role of High-Throughput Whole Genome Sequencing for the Diagnosis and Care of Atypical Diabetes

The prevalence of diabetes is 7.4% in France among people aged 20 to 79 years in 2015. We must also consider "pre-diabetes" (subjects with glucose intolerance), whose prevalence is equivalent to that of diabetes (2012 estimate). The incidence of diabetes is exploding both for type 2 diabetes, which represents 85% of diabetes, and for type 1 diabetes, which represents 10% of cases and starts one out of two times before the age of 20. Diabetes typing is essential to guide therapeutic choices, particularly the use of insulin. This typing is based on the pathophysiology of the disease, distinguishing insulinopenia from autoimmune causes in type 1 diabetes, monogenic diabetes, secondary or atypical diabetes and type 2 diabetes, where insulinopenia and insulin resistance coexist. Thus, while a formal biological diagnosis is possible for some forms of atypical diabetes and for type 1 diabetes, no biological parameter is currently available for type 2 diabetes, which remains a diagnosis of exclusion. As a result, diabetes represents a source of diagnostic and therapeutic erraticism, amplified by the clinical heterogeneity of type 2 diabetes, which is obvious and underestimated, and by a clinical phenotyping of patients that is often defective. The economic consequences are important because the health costs are very different depending on whether or not patients are treated with insulin. Type 1 and type 2 diabetes are examples of chronic, non-transmissible, multigenic, multifactorial diseases. However, less than 10% of the heritability of type 2 diabetes is currently explained by the associated genetic variants. And although genetic tests exist to diagnose certain monogenic diabetes, this diagnosis is made in less than 20% of cases, mainly in the presence of an atypical clinical presentation of diabetes. Moreover, there is no reason to rule out the hypothesis of paucigenic forms, at the interface of monogenic diabetes and multigenic forms as usually envisaged, as has been observed in chronic pancreatitis, which is also accompanied by diabetes. The study will be conducted according to a randomized trial design comparing two diagnostic strategies defined as follows: - Control strategy: in silico analysis of a panel of validated genes (ISApanel - Diabetome 1). Patients recruited along the control procedure will stay in their group using current genetic diagnosis practices and standard of care that may differ from one center to another. - Intervention strategy: whole genome sequencing coupled with multidisciplinary conciliation meeting. We plan to randomize one patient in the control group for two in the intervention group. The main objective of the study is to assess the contribution of whole genome sequencing (WGS) coupled with a multidisciplinary conciliation meeting (MCM) on diagnosis of atypical forms of diabetes compared to an in-silico analysis of a panel of validated genes (ISApanel), corresponding to current practice. The target population is 1020 adults with atypical diabetes for whom it is possible to obtain a blood sample.

Hybrid Closed Loop Insulin Pump and Bariatric Surgery in Patients with Type 1 Diabetes

Patients with type 1 diabetes and obesity are at risk of "double diabetes". Bariatric surgery may be indicated for these patients, to combat insulin resistance. Nevertheless, post-operative patients are at risk of hypoglycemia. At the same time, patients with type 1 diabetes can benefit from a hybrid closed loop insulin pump to improve diabetes control and reduce the occurrence of hypoglycemia. In type 1 diabetic patients who have undergone bariatric surgery and are treated with a hybrid closed loop insulin pump, continuous glucose measurement can be studied. In the medium and long term, the efficacy and safety of this system in this context will be described.

French Observational Study of Patients with Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma in Real-World Settings

Chronic lymphocytic leukemia (CLL) is the most frequent form of leukemia in the Western World. The disease is characterized by the accumulation and proliferation of mature, monoclonal, CD5+ B-cells with specific immunophenotype in the peripheral blood (above 5x109/L), bone marrow and secondary lymphoid organs. Small lymphocytic leukemia (SLL) is characterized by similar tumor cells but without increased lymphocyte count. In Europe, CLL has been identified as the second most frequent hematological malignancies after multiple myeloma (Eurocare 5 study) and its standardized incidence in the world has been estimated to be 4/100000 person-years for men and 2.1/100000 person-years for women. In France, 4674 new cases have been observed in 2018 (FRANCIM). A proportion of patients can initially be monitored only while others with symptomatic disease at diagnosis or during follow-up require therapies. The management of these patients have considerably changed over the last decade. Indeed, beyond chemo-immunotherapy, multiple targeted therapies have been approved on the basis of phase 2 and randomized phase 3 clinical trials and have subsequently been used in daily practice. The management of patients with SLL is similar to that of those with CLL. In addition to therapeutic advances, the advent of new sequencing technologies has also identified CLL genetic features that are now being incorporated in patient routine evaluation. Conventional chemo-immunotherapy (CIT) has been the long-standing option for CLL patient without TP53 disruption and different regimens have emerged depending on patient comorbidities (fludarabine-cyclophosphamide-rituximab, FCR; bendamustin-rituximab, BR; GA101-chloraminophene, G-CLB). These regimens fail to be effective in patients with TP53 disruption and alternative strategies are proposed for them. The CLL therapeutic panel is now enriched by oral kinase inhibitors targeting the B-cell receptor signaling. The Bruton's tyrosine kinase inhibitors (BTKi) have been shown to provide prolonged response, even in cases where CIT usually failed, such as patients harboring TP53 disruption. In relapsed/refractory patients, median PFS with the BTKi ibrutinib is 44 months. In the frontline setting, ibrutinib has recently been shown to result in superior PFS and less infectious complications than standard CIT regimens. The advent of the BCL2 (B-cell lymphoma 2) inhibitor venetoclax has recently added another option for the treatment of CLL patients. BCL2 is an antiapoptotic molecule governing mitochondrial apoptosis and is strongly expressed in CLL cells. Inhibiting BCL2 with venetoclax as monotherapy led to 79% response rate in the relapse/refractory setting. Combining venetoclax to rituximab demonstrated better PFS than bendamustine-rituximab in relapsed/refractory patients. However, these treatment approaches also come with new challenges that are difficult to-address in phase 3 clinical trials and that deserve larger scale studies and longer follow-up. The emergence of drug resistance, the changes of safety profiles to deal with in routine practice and the observance of these orally administered drugs are emerging as new concerns. How these compounds change the incidence of typical CLL complication such as Richter transformation, immune cytopenias and infections remains to be determined. A growing body of concerns is also raising regarding the unlimited administration of some of this the compounds (costs, resistance, tolerance). Finally, the optimal order of use of these drugs is unknown. The advent of the BCL2 (B-cell lymphoma 2) inhibitor venetoclax has recently added another option for the treatment of CLL patients 11,12. BCL2 is an antiapoptotic molecule governing mitochondrial apoptosis and is strongly expressed in CLL cells.

Systematic Use of DDAVP to Prevent Serum Sodium Overcorrection in Severe Hyponatremia

Multicentre, prospective, open-label randomized controlled superiority trial with stratification on the presence of neurological symptoms at inclusion and on the presence/absence of risk factors for central pontine myelinolysis (chronic alcohol abuse, malnutrition, serum potassium < 3.0 mmol/L). Patients in ICU with severe hyponatremia defined by SNa < 115 mmol/L or SNa < 120 mmol/L in the presence of neurological symptoms (convulsions, stupor defined by a Glasgow score <12 or signs of brain herniation) and a normal or decreased extracellular fluid volume will be included. After written informed consent, they will be randomized (1:1), using a computer-generated randomization scheme of various-sized blocks, stratified by the presence of neurological symptoms at inclusion (seizures, stupor defined as Glasgow score <12 or signs of brain herniation) and on the presence/absence of risk factors for central pontine myelinolysis (chronic alcohol abuse [defined according to World Health Organization definition], malnutrition [BMI<20.5 or weight loss >5% in 3 months], serum potassium < 3.0 mmol/L), through a centralized 24-hour Internet service (CleanWEB™), to receive standard hyponatremic treatment alone or standard hyponatremic treatment and DDAVP 4 μg/ml IV, after randomisation and for a total duration of 48 hours. Since administration of DDAVP leads to an important decrease in urine output and increase in urine osmolarity which are clinically obvious very rapidly, a single or double blind trial is not appropriate. However, all investigators will be unaware of aggregate outcomes during the study and brain MRI imaging will be performed and analyzed blinded to the randomization group
