Comparative Study of Human Immunodeficiency Virus Negative Host Talaromyces Between Voriconazole and Amphotericin Sequential Itraconazole Therapy

• Status: Recruiting
• Trial end date: 2021-12-30
• Target enrollment: 0
• Participant gender: All

Summary

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.
