Filter by:The objective of this study is to evaluate the performance, usability, and result interpretation of the INSTI® HIV Self-Test (referred to INSTI® HIV ST) in the intended use population across the United States (US). The INSTI® HIV Self-Test is a single use in vitro test that is used as a self-test for the detection of antibodies to HIV-1 and HIV-2 in human fingerstick blood. This study is designed to evaluate INSTI® HIV ST performance in the hands of non-professionals and untrained lay users who are inexperienced in HIV blood-based self-testing. The study aims to: To evaluate the clinical performance (i.e., diagnostic sensitivity and specificity) of the INSTI® HIV Self-Test in a lay user population. To assess the user's comprehension of the INSTI® HIV ST results (e.g., interpreting positive, negative, and invalid results). To evaluate the usability of the INSTI® HIV ST and understand users' experience in performing the test.
Primary humoral immunodeficiency (PHID), such as common variable immunodefiency, are the most common symptomatic primary immunodeficiency in adults, in France. Patients are more prone to infections (particularly bacterial upper and lower respiratory tract infections), auto-immunity and atopic manifestations. Morbidity and mortality in PHID are mainly linked to the presence of bronchiectasis, which can lead to infections and to chronic respiratory failure. However, bronchiectasis in these patients can be asymptomatic for a long time. There is no known predictive factors to identify patients more susceptible to develop bronchiectasis and notably, there was no link between the number of previous infectious episodes and bronchiectasis. A marked IgM deficiency and switched memory B cell deficiency might be associated with bronchiectasis. Thoracic CT-scan is recommended at PHID diagnosis but there is no guideline for follow-up, thus leading to bronchiectasis being under-diagnosis or leading to delayed diagnosis
Inborn Errors of Immunity (IEI) are a heterogeneous group of disorders characterised not only by an infectious diathesis, but by a wide variety of other clinical manifestations. Lymphoma is one of the most common malignancies in children and may be the first clinical manifestation of IEI, thereby 'hiding' the immune defect and delaying genetic/immunological diagnosis. Lymphomas, especially non-Hodgkin's lymphomas (NHL) are frequently associated with congenital defects of the immune system, in particular diffuse large B-cell lymphoma and Burkitt's lymphoma. Preliminary analyses conducted on 6 patients diagnosed with NHL allowed the identification of genetic variants in genes associated with IEI. In clinical practice, the diagnosis and choice of therapeutic treatment in patients with immunodeficiency-associated lymphoma are decisive and, due to the complex pathophysiology of the disease, it is not always possible to identify the boundary between benign and malignant proliferation. The identification of an undiagnosed immunodeficiency in patients with lymphoma will ensure the opportunity to apply targeted therapies, such as allogeneic haematopoietic stem cell transplantation, instead of standard clinical management based mainly on chemotherapy. The study aims to identify possible congenital defects of immunity, i.e. genetic disorders affecting the immune system, as responsible for the development of haematological malignancies. Through a multidisciplinary approach involving immunological analyses, genetic analyses and a thorough examination of clinical manifestations, we aim to characterise the immunological component underlying the development of paediatric lymphomas.
The goal of this observational study is to determine the incidence and spectrum of opportunistic infections among Chinese HIV/AIDS patients at this stage, to find intervention targets, to construct an early warning prediction model, and to give an individualized program with integrated immune function to obtain salvage opportunities for patients.The main questions it aims to answer are: - Describe the populations and characteristics of pathogenic microorganisms involved in HIV co-infection, map the spatial and temporal changes in the infection system of pathogenic microorganisms, and evaluate their impact on disease regression. - Explore the mechanism of interaction between pathogenic microorganisms and host autoimmune deficiencies. - Discover early warning and predictive markers and immunological indicators of pathogenic microorganisms, and explore new technologies and programs to reduce the mortality rate of infection.
Moesin deficiency was initially described in 7 male participants aged 4 to 69 years and is characterized by lymphopenia of the 3 lineages and moderate neutropenia. Genetically, 6 out of 7 participants had the same missense mutation in the moesin gene located on the X chromosome. The 7th patient has a mutation leading to the premature introduction of a STOP codon into the protein.Clinically the 7 participants with X-linked moesin-associated immunodeficiency all presented with recurrent bacterial infections of the respiratory, gastrointestinal or urinary tracts, and some had severe varicella.Therapeutically, in the absence of a molecular diagnosis and due to his SCID-like phenotype, one patient was treated with geno-identical hematopoietic stem cell transplantation . The remaining are untreated or treated with immunoglobulin substitution and/or prophylactic antibiotics. Since this study, the moesin gene has been integrated into DNA chips used for the molecular diagnosis of immune deficiencies in several countries. Physicians in Canada, the United States, Japan, South Africa and Europe have contacted us with a total of 16 known participants to date. Because of their very low severe, uncontrolled CMV infection and the absence of treatment recommendations, two 2 American participants were treated with allogeneic transplantation with severe post-transplant complications (1), and one of the participants died as a result of the transplant. Management of XMAID participants therefore varies widely from country to country, depending on age at diagnosis and clinical picture. It ranges from no treatment treatment (associated with recurrent infections and skin manifestations), IgIv substitution and/or antibiotic prophylaxis antibiotic prophylaxis, with low toxicity and apparent efficacy, and allogeneic transplantation, with all the risks risks involved (graft-related toxicity, graft versus host, disease, rejection, risk of infection). The Investigators therefore feel it is important to review the diagnosis, clinical presentation and management of X-MAID participants. The study the investigator propose will enable to understand the presentation of X-MAID participants, establish guidelines and provide the best treatment for each patient according to his or her clinical picture
The Human Immunodeficiency Virus (HIV) epidemic persists in France, with approximately 6000 new cases per year. Various prevention tools against HIV exist, including condoms, regular testing, Post-Exposure Prophylaxis (PEP), HIV treatment for seropositive partners, single-use disposable injection equipment for drug use and pre-exposure prophylaxis (PrEP). Continuous or on-demand PrEP with tenofovir disoproxil fumarate/emtricitabine has proven effective in reducing the risk of HIV infection. France was the first European country to authorize PrEP, leading to an unprecedented impact on seropositivity discovery rates in 2018, with a 7% decrease in new infections compared to 2017. However, the effectiveness of PrEP can be hindered by challenges in retaining users within the healthcare system. According to the EPIPHARE report, which has been monitoring Truvada® or generic PrEP use since 2017, a substantial proportion of new users do not receive PrEP renewal in the first 6 months after initiation. Such early interruptions, increasing in frequency, affected around a quarter of individuals who initiated PrEP in the second half of 2021. A recent study reported that these early interruptions have a significant detrimental impact on PrEP effectiveness in real life, especially among those under 30 years old and in socio-economic precarious situations. The main barriers to PrEP adherence are multifactorial, including social precarity, limited PrEP access, and a low perception of HIV risk. To address this, in France, general practitioners have been authorized to issue initial PrEP prescriptions since June 1, 2021. The future challenge is to increase PrEP use and optimize retention to combat the HIV epidemic, relying significantly on general medicine. The goal of our study is to broaden PrEP access by optimizing its initial prescription in general medicine and to assess user retention in PrEP care through the established partnership between general practitioners and patients. The research will be conducted in collaboration between Saint Louis Hospital in the 10th arrondissement of Paris and general practitioners willing to participate in the study, located in the 3rd, 10th, 11th, 13th, and 19th arrondissements. Participating general practitioners may be in private practice, employed in health centers, or working in health houses. As part of the study, general practitioners will receive training from the infectious diseases department of Saint-Louis and Lariboisière hospitals. This training will be both theoretical and practical, with the opportunity to attend initiation and follow-up PrEP consultations in the department. A dedicated phone line in the infectious diseases department of Saint Louis Hospital will be available for participating general practitioners seeking specialized advice. They will be encouraged to register as PrEP prescribers in their appointment scheduling software. Patients will be informed of the study objectives and its process by the general practitioner, and their oral non-opposition will be collected. Each inclusion consultation will last approximately 20-40 minutes, allowing the general practitioner to prescribe PrEP, conduct the usual care consultation, and collect clinical, demographic, socio-economic, lifestyle, medical history, and patient vaccination data on a dedicated data collection form. The follow-up duration will be two years, with consultation frequency matching that of regular PrEP follow-ups, and data collection will occur at M6, M12, M18, and M24 using a dedicated data collection form. Data collected during inclusion and follow-up consultations will be anonymized and integrated into the electronic Clinical Report Form. During each PrEP consultation (initiation and follow-up), general practitioners will provide patients with a PrEP prescription if the pre-PrEP biology report allows it (according to HAS (Haute Autorité de Santé) recommendations). For patients who have not been attending consultations, a telephone survey will be offered to inquire about PrEP continuation and collect information on follow-up or reasons for stopping PrEP.
The clinical trial is a dose-escalation, randomized, double-blind, placebo-controlled phase I study at a single center to evaluate the safety, tolerability and immunogenicity of HIV Therapeutic DNA Vaccine, ICVAX, in clinically stable HIV patients under ART treatment.
To evaluate the safety, efficacy and pharmacokinetic properties of Boya's IVIG preparation in participants with PID aged less than 60 years and more than 6 years.
The main aim of this study is to determine the impact of digital health technology, such as Alexa Skill, used to support the initiation of home-based subcutaneous immunoglobulin (SCIG) treatment, treatment management, and overall participant experience.
Patients with CVID will be offered to participate in this observational trial during the routine annual visit in the outpatient clinic at the Center of chronic Immunodeficiency (CCI) of the University Medical Center Freiburg, Germany. Clinical and laboratory data at the time of presentation will be assessed. Additionally, parameters of abdominal ultrasound, duplex sonography of the liver and spleen, and liver and spleen stiffness at the time of presentation will be evaluated. If applicable, clinical and/or interventional parameters indicating clinically significant portal hypertension (i.e. presence of varices or portal-hypertensive gastropathy in esophago-gastroduodenoscopy, presence of ascites) within 12 months prior and after the index visit will be assessed. During the visit, serum/plasma samples and peripheral blood mononuclear cells (PBMC) are collected and stored in an associated biobank.
