NCT ID: NCT05128110 Completed - Hemostasis Clinical Trials

Study of Hemostasis During the Atrial Fibrillation Ablation Procedure

EHPAFAVE
Start date: January 1, 2021
Phase:
Study type: Observational

Anticoagulation monitoring is done by monitoring the ACT (Activated Clotting Time) with an objective greater than 300 s. Until now, treatment with direct oral anticoagulant (for the prevention of thromboembolic events of atrial fibrillation) was interrupted a few days before the procedure in order to limit the risk of per-procedural bleeding. However, 3 recent randomized studies concerning the 3 DOACs available suggest that treatment should not be interrupted during the entire operative period. The operation therefore takes place under double anticoagulation with a direct oral anticoagulant and unfractionated heparin. Under these conditions, ACT monitoring can no longer be considered a reliable means of measuring the level of anticoagulation. It was therefore necessary to explore the hemostasis of these patients in a broad way in order to avoid any risk of overdose of UFH (Unfractionated Heparin) during the procedure.

NCT ID: NCT05128097 Recruiting - Geriatric Syndromes Clinical Trials

Preventive Approach for the Management of the Main Geriatric Risks

Ger-e-Tec
Start date: June 1, 2020
Phase:
Study type: Observational

Nowadays, EHPAD residents are polypathological (cognitive and psycho-behavioral pathologies, undernutrition, IC, diabetes, COPD, IR, etc.) and multi-medicated. From a medical point of view, this implies the need for regular monitoring and a high level of medical or even multidisciplinary expertise for the healthcare team. The objective of the GER-e-TEC ™ project is to provide these complex patients with telemedicine tools allowing protocolized and personalized, non-intrusive monitoring. The GER-e-TEC ™ project more specifically takes into account the significant issues in nursing homes of aging residents with the main geriatric syndromes (fall, undernutrition, cognitive-behavioral disorders, iatropathogeny, etc.) The objective of the work undertaken is to develop a codified preventive approach for the management of the main geriatric risks, in order to avoid the occurrence of an acute decompensation factor in the elderly.

NCT ID: NCT05128084 Recruiting - Clinical trials for Congenital Heart Disease in Children

Amotosalen and Platelet Transfusion in Pediatric Heart Surgery

TransPédia
Start date: October 1, 2020
Phase:
Study type: Observational

High level of security during blood transfusion has been achieved by donor selection and pathogen detection using serology or direct identification. Nevertheless, blood banking becomes hazardous during epidemic outbreaks or facing new pathogens. Amotosalen, a psoralen, targets nucleic acids and destroys them after ultraviolet exposure, resulting in inactivation of pathogens. Treatment inoccuity and efficacy have been demonstrated but preservation of platelet functions after treatment is still debated. Previous studies focused on hematological patients. There is no evidence for an increased requirement of transfused platelets to achieve platelet count target. Studies in heart surgery are lacking. The investigators perform a multicenter, retrospective, "before/after", controlled study in minor patients requiring heart surgery with cardiopulmonary bypass. One center (Strasbourg) uses Amotosalen-treated platelet concentrates since 2006 (control arm). This treatment becomes available in Bordeaux in October 2017 (intervention arm). There is two periods of inclusion: one "before" (January 2016 to June 2017) and one "after" (January 2018 to June 2019).

NCT ID: NCT05127967 Completed - SPG7 Clinical Trials

Consequences of Mutations in the SPG7 Gene at the Heterozygous State

CONSP-HET7
Start date: November 16, 2021
Phase: N/A
Study type: Interventional

Paraplegin, encoded by the SPG7 gene, is an ATP-dependent mAAA protease located in the inner mitochondrial membrane. Its function is not fully understood. Mutations in the SPG7 gene are responsible for spastic paraplegia type 7. Although spastic paraplegia type 7 is considered to be a recessive disease, some clinical observations also point to a detrimental effect of a variant in SPG7 in the heterozygous state. Thus, the presence of a single mutated variant of the SPG7 gene could be a risk factor for the development of neurological diseases. This has important implications for genetic counseling of patients and for the understanding of the function of the SPG7 protein and the mechanisms of disease development.

NCT ID: NCT05127681 Terminated - Osteoporosis Clinical Trials

Bone Microarchitecture in Men With Hemophilia

HEMOS
Start date: August 1, 2023
Phase: N/A
Study type: Interventional

Hemophilia A and B are hereditary sex-linked deficiencies of coagulation factors VIII and IX characterized by bleeding. Their modern therapy increases life expectancy and risk of age-related diseases, e.g., osteoporosis. Hemophilia-specific risk factors impair formation of peak bone mass and accelerate bone loss. Fractures are more frequent in hemophilic men vs. age-matched men and induce bleeding which is aggravated by manipulations and surgical intervention. The hypothesis of this study is that hemophilic men have poor bone microarchitecture (assessed by High-resolution peripheral quantitative computed tomography (HR-pQCT)) related to an imbalance between bone formation and resorption (assessed by bone turnover markers (BTM) and bone biomarkers). The study aims to assess the difference in low trabecular number (Tb.N) at the distal radius between hemophilic men (cases) and age- height-weight-ethnicity and smoking-matched healthy men (controls). Correlation between BTM and Tb.N will be also studied. Biologic markers of bone remodeling (C-terminal telopeptide of type I collagen (PINP), N-terminal propeptide of type I procollagen (CTX-I), periostin) will be studied.

NCT ID: NCT05127226 Active, not recruiting - Angelman Syndrome Clinical Trials

HALOS: A Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of Multiple Ascending Doses of ION582 in Participants With Angelman Syndrome

Start date: December 22, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and tolerability of ascending doses of ION582 administered intrathecally in participants with Angelman syndrome.

NCT ID: NCT05127187 Completed - HIV Infections Clinical Trials

Estimation of the Prevalence of HIV, Hepatitis C and Hepatitis B Infection Among Detainees in the Nîmes Administrative Detention Center

TRODUMCRA
Start date: February 8, 2022
Phase:
Study type: Observational

People in Administrative Detention Centers often come from areas of medium or high HIV, hepatitis C & B endemic, and are often unaware of their serological status. Currently, HIV, hepatitis C & B screening is not systematically performed at the CRA of Nîmes, and when performed, serological tests are used. The main disadvantage of this method is the length of time it takes to obtain the results, with subjects frequently discharged before receiving their results. To improve the care of these vulnerable persons, the aim of this study is to estimate the prevalence of HIV, hepatitis C and hepatitis B in the detainees of the administrative detention center of Nîmes, by systematically screening with a rapid diagnosis test. In case of a positive rapid diagnosis test test, a serology test will confirm the rapid diagnosis test result.

NCT ID: NCT05126914 Not yet recruiting - Epilepsy Clinical Trials

Multicentre Real-life Follow-up Study of Rare Epileptic Syndromes in Children and Adolescents

EPIRARE
Start date: December 2021
Phase:
Study type: Observational

Rare epilepsies as a whole account for 20-30% of epilepsies, but knowledge about prognostic factors is currently limited. This means that it is difficult to provide adequate information to families at diagnosis and during follow-up. Prognostic factors are also important for management as they can have an impact on the patient's outcome (time to intervention, choice of one molecule over another, etc.). Finally, few treatments are currently available for these epilepsies. One of the limitations to the development of treatments is the lack of real life data as it is difficult to create reliable primary endpoints such as the rate of patients becoming seizure free naturally compared to a therapeutic intervention. The aim of this real-life study is to evaluate the response to treatment as well as to see the evolution of cognitive and psychiatric comorbidities. As explained above, there are very few randomised trials except for 3 rare epilepsies (infantile spasm syndrome, Dravet syndrome, Lennox-Gastaut syndrome). This has led to the virtual absence of management recommendations, including for the three syndromes mentioned above, where attempts at treatment algorithms have been proposed, although these have not been able to be considered as evidence-based recommendations. As a result, there is some diversity in the management of rare epilepsies from one centre to another. However, this diversity in management can be an asset in a real-life study. This will make it possible to compare different management methods, both in terms of seizure control and medium-term outcome.

NCT ID: NCT05126849 Recruiting - Clinical trials for Refractory Idiopathic Aplastic Anemia

Haploidentical Allogeneic Hematopoietic Stem Cell Transplantation With Post-transplant Cyclophosphamide in Patients With Acquired Refractory Aplastic Anemia or in Relapse After Immunosuppression

HAPLO-EMPTY
Start date: January 6, 2022
Phase: Phase 2
Study type: Interventional

Outcomes for patients with severe aplastic anemia (SAA) who are refractory to first-line immunosuppressive therapy (IST) and who lack a matched unrelated donor (MUD) remain poor. Recently, the use of eltrombopag (ELT) has shown blood count improvements in 40% of these patients. However, most refractory patients do not respond to ELT or other second-line treatment and are therefore exposed to life-threatening infections, and bleeding. During the past 2 decades, there has been a significant decrease in infection-related mortality in patients with SAA unresponsive to initial IST but clonal evolution including paroxysmal nocturnal hemoglobinuria (PNH), myelodysplastic syndrome (MDS), and acute myeloid leukemia (AML) still occur in the long-term with a grim prognosis. Overall, the overall survival of such patients with acquired refractory SAA to ELT is about 60-70% at 2 years. Hematopoietic stem cell transplantation (HSCT) using alternative donor sources (i.e., mismatched unrelated donors, cord blood (CBT), and haplo-identical family donors) may be curative in patients with refractory SAA, despite carrying much higher rates of complications than in transplantations from matched related or unrelated donors. Recently, our group showed that CBT is a valuable curative option for young adults with refractory SAA. However, not all patients have available CB and CBT treatment related mortality is high in adult patients. Haploidentical (haplo) related donor Stem Cell Transplantation (haplo-SCT) have improved dramatically outcomes using T-cell replete grafts with administration of post-transplantation cyclophosphamide (PTCy). Preliminary results in a little number of patients with refractory SAA at Kings college (London, UK) and John Hopkins (Baltimore, USA) seem promising. The investigators retrospectively analyzed data from 36 patients (median age 42 years) transplanted between 2010 and 2017 in Europe on behalf of the SAA working party of the European Blood and Marrow Transplantation group. The 1-year overall survival was about 80% suggesting that this approach might be a valid option in this particular poor clinical situation. The main objective of this study is to demonstrate a benefit in term of the 2-year overall survival rate from 60% (historical rates in patients with acquired refractory idiopathic aplastic anemia) up to 80% using haplo-SCT with PTCy.
