NCT06594861
In this study, individuals with autoantibodies against Ro/SSA and La/SSB will be followed with regard to clinical manifestations and immunological parameters to identify immunological changes, environmental factors, and early clinical symptoms that characterize the progression from serological autoreactivity to clinically manifest disease.
NCT05867524
The aim of the project is to investigate whether or not there are any difference in cardiometabolic outcomes in individuals with high or low levels of c-aAb against interleukin-6 (IL-6). The study is the first to investigate individuals with extreme amounts of c-aAb levels against IL-6 and to contribute with knowledge on a possible new phenotype.

Chronic heart failure (CHF) is one of the major causes of death in Western societies. Evidence has accumulated that functionally active autoantibodies directed against the beta1 adrenergic receptor (β1 AAb) are of pathophysiological relevance for the development and progression of cardiomyopathy and associated CHF. BC 007 is under development for targeted neutralisation of autoantibodies directed against G protein coupled receptors, including β1 AAb. This is an open label, three-centre, randomised phase 2a study in participants with chronic HFrEF. The study will evaluate whether BC 007 causes a persistent neutralisation of the β1 AAb demonstrated by a negative β1 AAb status up to 12 months. Participants will be randomised in a 2:1 ratio to the treatment arm (BC 007) or the control arm (untreated). Treatment is repeated once up to month 11 if the participant's β1 AAb were not neutralised after 1st dosing on day 1 or reoccur.

Through a multi-center large-sample non-randomized controlled study, the effect of voriconazole, amphotericin B sequential itraconazole therapy on Talaromyces in Human Immunodeficiency Virus（HIV）negative hosts were compared to clarify whether the two therapies were equivalent; A comprehensive efficacy evaluation system and standard treatment program was established to provide a basis for standardized treatment of Talaromyces in Human Immunodeficiency Virus negative hosts.The observational indicators included: 2-week all-cause mortality; 24-week all-cause mortality; clinical improvement time; level of decrease of fungus in the blood culture medium two weeks before treatment; recurrence; appearance of adverse drug reaction at the level 3 and above. Dynamically monitor the immune cells and factors like anti-Interferon-γ autoantibodies, Interferon-γ, Th1/Th2, and Th17/Treg in the HIV-negative Talaromyces host microenvironment, and observe the host's immune status and its change. 3. study the effect of absence of Interferon-γ and Interferon-γ Receptor (IFN-γR）on the activation and function of anti-Interferon-γ autoantibodies, Th1/Th2, and Th17/Treg by establishing a Talaromyces mouse model that knocks out the Interferon-γ and IFN-γR gene and a IFN-γ silenced cell model; Study the effect of anti-IFN-γ autoantibody on the activation and function of IFN-γ、Th1/Th2、Th17/Treg by increasing its titer in vitro and vivo; determine by which path the anti-IFN-γ autoantibody of HIV-negative host influences its immune regulation mechanism; finally, the intervention effect of IFN-γ on high titer anti-IFN-γ autoantibodies is studied, providing a new idea for immunotargeted therapy.
