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.

RECRUITINGNumber of Participants with all-cause mortality
defined as the absolute risk of death from any cause during the first 2 weeks
Time frame: up to 2 weeks
Number of Participants with all-cause mortality
defined as the absolute risk of death from any cause during 24 weeks
Time frame: up to 24 weeks
Number of Participants with Clinical resolution of talaromyces
Clinical resolution of talaromyces was defined as a temperature of less than 38°C (100°F) for 3 days, resolution of skin lesions, and tertile blood cultures. Early fungicidal activity was defined as the rate of decline in blood T. marneffei colony forming units (CFUs).
Time frame: 3 days
Number of Participants with Early fungicidal activity
defined as the rate of decline in blood T. marneffei CFUs from sterical blood cultures obtained during the first 2 weeks.
Time frame: up to 2 weeks
Number of Participants with Relapse of talaromyces
defined as the recurrence of symptoms and a positive fungal culture from any sterile site that led to reinduction of therapy in patients who had achieved clinical resolution.
Time frame: an average of 1 year
