Active clinical trials for "Immunologic Deficiency Syndromes"

Patients with chronic lymphocytic leukemia (CLL) are at increased risk of infections as compared to age matched controls, with infections being a major cause of morbidity and mortality. Previous studies have shown that patients with CLL have both hypogammaglobinemia and impaired humoral immunity as defined by vaccine responses to both polysaccharide and peptide antigens. Attempts at decreasing infections in CLL have included therapy with prophylactic antibiotics and intravenous immunoglobulin. In general clinical practice and in previous studies, patients have started IV immunoglobulin replacement therapy if they have a history of serious infection or hypogammaglobinemia (defined as Immunoglobulin G below 500-600 g/dL), but vaccine responses have not been evaluated. This study will identify CLL patients with humoral immunodeficiency by checking both Ig levels and vaccines responses. In patients with impaired humoral immunity, the investigators will use subcutaneous immunoglobulin replacement to show this intervention will increase Ig levels, protective antibody titers, and be well tolerated.

This study will be conducted in two stages and will test the safety/tolerability, pharmacokinetics (how the body handles study drug) and pharmacodynamics (effects on the immune system and the virus) of the study drug ABBV-181 in Human immunodeficiency virus (HIV)-1 infected participants undergoing Antiretroviral therapy (ART) interruption.

In this randomized, open-label study, the investigators will assess whether CytoSorb hemoperfusion will prevent or attenuate the development of immunoparalysis in healthy volunteers undergoing repeated experimental endotoxemia.

The purpose of this study is to assess the safety and immunogenicity of M72/AS01E vaccination in virally suppressed, antiretroviral-treated participants with human immunodeficiency virus infection (HIV).

In this study, multiple myeloma participants with secondary immunodeficiency (SID) will be treated with HyQvia according to their clinic's standard practice. The study's main aim is to look into infusion parameters of HyQvia administration.

Data are limited regarding the effectiveness and safety of generic velpatasvir plus sofosbuvir (VEL/SOF) with or without ribavirin (RBV) for the treatment of hepatitis C virus (HCV) in patients with human immunodeficiency virus (HIV) coinfection. We aim to compare the effectiveness and safety of VEL/SOF with and without RBV for 12 weeks in HIV/HCV-coinfected and HCV-monoinfected patients The antiviral responses and the adverse events (AEs) are compare between the two groups. The characteristics potentially related to sustained virologic response 12 weeks off therapy (SVR12) are analyzed.

Recommendations concerning the administration of Zostavax® in patients with antibody deficiency are unclear. The investigators plan to assess the immunogenicity and safety of Zostavax® in patients with antibody deficiency as compared with healthy volunteers.

This is a single-site, longitudinal, open-label, interventional study for evaluating the effect of maraviroc on hepatitis C viral levels in patients infected with both hepatitis C and human immunodeficiency virus (HIV) and taking antiretroviral therapy for HIV.

This study focuses on the integration of HIV and NCD screening and care. The investigators will conduct a randomized controlled trial examining the efficacy and cost-effectiveness of the intervention strategy in Kisarawe District, Tanzania, a rural area 40 KM southwest of Dar es Salaam. The study will match two similar HIV care and treatment centers (CTC) in the District, one of which will be randomized to receive the enhanced intervention which will integrate diabetes (DM) and hypertension (HTN) screening with the existing HIV testing program, and integrate care for DM and HTN into the HIV care program. Comparisons of the community HIV testing rates in the two communities, engagement in HIV care among those testing positive, and 24-month retention in HIV care will be assessed among a cohort of 107 newly enrolled patients per community. Specifically, the aims are to determine: Whether integrating DM and HTN screening with HIV testing will increase the uptake of community-level HIV testing. If integrating DM/HTN care with HIV care enhances engagement in HIV care. Whether integration of DM/HTN care with HIV care enhances retention in HIV care for those newly enrolled in HIV care. The cost-effectiveness of integrating NCD screening and care with HIV screening and care with regard to the incremental cost per HIV infected client engaged in HIV care, and cost per newly enrolled HIV client retained in HIV care over 24-months.

Sleep problems, such as insomnia, are more frequent and intense in individuals living with HIV. These sleep difficulties can increase the difficulties in thinking and concentrating. Digital cognitive behavioral therapy for insomnia (dCBT-I) is a computer-based treatment intervention that provides strategies to improve sleep. This intervention has been shown to improve sleep and daytime function (concentration, productivity) in people with insomnia. However, the effects of this intervention in people living with HIV are unknown.
