Active clinical trials for "Immunologic Deficiency Syndromes"

Treatment Study to assess of safety and efficiency of T cells receptor (TCR) alfa beta depleted graft for hematopoietic stem cell transplantation (HSCT) from haploidentical and unrelated donors in patients with primary immunodeficiency diseases

This study will evaluate the effectiveness of portable colposcopy when compared to conventional colposcopy (25x magnification of the cervix, the gold standard) and Visualization Inspection with Acetic acid (VIA, with 1x magnification, the accepted low-resource method). Half the participants will be evaluated for cervical pathology by portable colposcopy after VIA assessment, while the other half will be evaluated by conventional colposcopy. This study also will use collected lab specimens for human papillomavirus (HPV)-positive women to determine those HPV genotypes most prevalent among higher grade disease cases (CIN II+) and among the sub-group of human immunodeficiency virus (HIV)-positive women.

The primary purpose of this study is to assess the rate of early discontinuation from randomized Human Immunodeficiency Virus (HIV) Postexposure Prophylaxis (PEP) for any reason other than confirmation of the negative HIV infection status of the index person in patients receiving HIV PEP for at least 28 and a maximum of 30 days.

The purpose of this study is to evaluate the safety, efficacy and pharmacokinetics of Immune Globulin Intravenous (Human) IVIG-SN™ in subjects with primary immunodeficiency diseases.

The main objective of this study is to evaluate and to compare the specific antibody response to a " prime-boost " vaccine strategy combining the seven valence pneumococcal conjugate vaccine (PnCj) prime at W0 followed by the administration of the pneumococcal capsular polysaccharide vaccine (PPS) boost at W4, to the administration of the pneumococcal capsular polysaccharide vaccine (PPS) alone at W4 in patients with common variable immunodeficiency.

HIV related cognitive impairment still occurs despite highly active antiretroviral therapy (HAART). HIV disease affects the brain in 20-40% of patients with advancing HIV disease; leading to varying degrees of cognitive impairment, recently termed HIV associated neurocognitive disorders (HAND). HAND may occur in patients who are virally suppressed in both blood and CSF. Patients with HIV Associated Neurocognitive Disorders (HAND) who are virally suppressed in both their blood and cerebrospinal fluid (CSF), whilst on a highly active antiretroviral therapy (HAART) regimen may have significant cognitive improvement with HAART intensification with the medication Maraviroc; compared to those who remain on their existing regimen. This study will be a prospective, interventional, randomised and unblinded controlled clinical trial. The aim of this study will be to determine whether HAART intensification with the medication Maraviroc, leads to significant improvement in HIV associated neurocognitive disorders (HAND). Patients with the recent progression (within 6 months) of HAND (validated by neuropsychological assessment) on HAART, who are virally suppressed (<50 copies per ml) in blood and CSF will be randomised to have their existing HAART regimen intensified with Maraviroc, or not. The control arm will remain on their medication regimen as prescribed. The target is to enrol 70 patients into the control group, and 70 patients into the Maraviroc intensification group. Patients will undergo baseline neuropsychological testing, MRI, blood tests, and cerebrospinal fluid (CSF) tests (via a lumbar puncture). The methods used to determine the effectiveness of adding Maraviroc, will include further neuropsychological assessment at 6 months, and neuropsychological assessment, MRI and CSF assessment again at 12 months. Neuropsychological testing completed at 6 and 12 months will be completed by a "blind assessor", in that they will have no knowledge of which arm (treatment or control) the participant is enrolled in. An evaluation (neuropsychological testing) will be performed should the patient deteriorate during the course of the study, as recognised by the patient's managing physician. At the end of the study protocol (12 months) the patient's HAART therapy will be managed by their primary physician.

This study will compare safety, efficacy, and tolerability of a two drug regimen of dolutegravir (DTG) plus (+) lamivudine (3TC) administered once daily with DTG plus two nucleoside reverse transcriptase inhibitors (Tenofovir [TDF]/Emtricitabine [FTC] fixed dose combination [FDC]) administered once daily in human immunodeficiency virus (HIV) 1 infected adult participants that have not previously received antiretroviral therapy. The study is designed to demonstrate the non-inferior antiviral activity of DTG plus 3TC regimen to that of DTG plus TDF/FTC FDC and will characterise the long term antiviral activity, tolerability and safety of DTG plus 3TC through Week 148. Approximately, 700 participants will be randomised 1:1 to receive DTG + 3TC or DTG + TDF/FTC FDC. Participants will be stratified by screening HIV 1 ribonucleotide nucleic acid (RNA) levels and by screening CD4+ (cluster of differentiation 4) cell count.

Title: Investigation of neutrophil defects associated with periodontal disease and tooth loss in children. A clinical study. Objectives: The primary objective of this study is: To investigate presence of periodontal disease and response to periodontal treatment in children affected by neutrophil defects The secondary objectives of this study are: To investigate presence of other dental diseases in children affected by neutrophil defects To assess oral microbiological and inflammatory parameters in children affected by neutrophil defects Primary outcomes: The primary outcomes are (a) presence of periodontal disease as assessed by clinical factors: probing pocket depth, attachment level, bleeding on probing and radiographic bone loss) (b) microbiological and host response factors: detected in periodontal pockets and gingival crevicular fluid and (c) response to treatment Study sample: Children affected by neutrophil defects and meeting outlined inclusion and exclusion criteria Number of participants: 50 children Study design: This is a longitudinal treatment study. All participants will attend for 4-7 visits during the study as outlined below: Screening visit (visit 1): consent procedure, dental examination, saliva and plaque sampling Baseline visit (visit 2):, detailed periodontal examination, dental radiographs, sampling of gingival crevicular fluid and, if appropriate scaling, polishing and oral hygiene instructions Non-surgical periodontal treatment (visit 3A to 3D, max 4 sessions): oral hygiene instructions and supra- and sub-gingival debridement (under local anaesthesia if necessary) Follow-up Visit (visit 4, 4th to 7th visit) (six months following treatment): detailed dental examination, oral hygiene instructions, sampling of saliva, subgingival plaque and gingival crevicular fluid, tooth scaling and polishing.

This study will evaluate the efficacy and safety of glecaprevir/pibrentasvir (ABT-493/ABT-530) in non-cirrhotic chronic hepatitis C virus (HCV) genotype (GT)1 to GT6-infected Asian participants with or without human immunodeficiency virus (HIV) co-infection who are HCV treatment-naïve or treatment-experienced with interferon (IFN) with or without ribavirin (RBV), OR sofosbuvir with RBV with or without IFN.

Combined antiretroviral therapy (cART) efficiently suppress viral replication in majority of AIDS patients. The morbidity and mortality of the disease has dramatically decreased over the past 20 years. However, chronic human immunodeficiency virus-1 (HIV-1) infection lead to profound immune defects in some advanced AIDS patients who often develop with severe opportunistic infections (OIs), severe cachexia and other deadly complications, which accounts for the major death group even under cART. Up-to-date, there are no effective immune interventions to restore host holistic immunity for advanced AIDS patients.
