- Peking University People's Hospital
- Brief Summary
The goal of this observational study is to identify the duration of posaconazole-initiated antifungal treatment for IPA in patients with hematological malignancies and to explore the value of monitoring immune factors and cells in IPA treatment in order to assess practices in IPA management in Chinese hematology patients including tools to evaluate duration and discontinuation. The main question it aims to answer is:
Does any indicators that could be used to guide the duration of IPA treatment? Does immune factors have value in monitoring IPA treatment? We will not do any interventions to participants. Participants will be monitored routinely for their clinical characteristics, microbiological test( including G/GM Test, Blood culture), Imaging examination, Blood routine, the number and function of immune cells, cytokines(IL-1β/IL-2/IL-4/IL-8/IL-10/IL-12/IL-17/IFN-α/IFN-γ/TNF-α)， and we will collect these datas for analysing.
- Detailed Description
1. A total of 15 patients will be involved in the study.
2. For each patient, the investigator will first evaluate the patient to determine if the patient meets the enrollment criteria and does not meet any of the exclusion criteria.
3. For the patients included in the study, the investigators will collect their blood RT, immune cell count and function, and cytokine levels (including IL-1β/IL-2/IL-4/IL-5/IL-6/IL-8/IL-10/IL-12/IL-17/INF-γ/INF-α/TNF-α et al).
4. Closely monitor the patient's status and discontinue antifungal therapy if the patient meet the 4 critera: ①PMNs recovery\>500；②previous signs/symptoms of active IPA (such as fever) has been resolved; ③nagative mycological evidence; ④CT: the reduction in the size of the lesion must exceed 90% or stable cave. If the patient does not meet any of these criteria, antifungal therapy is continued until the 4 critera are met.
5. Blood RT, neutrophil count and function, and cytokine levels (IL-1β/IL-2/IL-4/IL-5/IL-6/IL-8/IL-10/IL-12/IL-17/INF-γ/INF-α/TNF-α) were collected at the time of stopping antifungal therapy and at 2, 4, 8, and 12 weeks after stopping treatment. At the same time, the patient's symptoms (cough, hemoptysis, fever, etc. )and signs (chest pain, etc. ) were observed and the patient's microbiology examination results (blood G/GM text, fungal culture, etc. ) and imaging examination results (CT, etc.) were collected at the follow-up.
6. Follow-up will be conducted instantly if any symptom, sign, or text result suspected IPA after discontinuation.

IFI-free survival rate on 2/4/8/12 weeks after discontinuation 12 weeks after discontinuation of posaconazole-initiated antifungal therapy The IFI-free survival rate of patients on 2/4/8/12 weeks after discontinuation of antifungal therapy
Clinical success rate of posaconazole-initiated antifungal therapy 12 weeks after discontinuation of posaconazole-initiated antifungal therapy The rate of patients who achieved clinical remission after posaconazole-initiated antifungal therapy
The proportion of patients who restarted treatment after discontinuation 12 weeks after discontinuation of posaconazole-initiated antifungal therapy After discontinuation of posaconazole-initiated antifungal therapy ,the rate of patients who restarted treatment of antifungal
Analysis of criteria that could be used to guide the discontinuation of IPA treatment 12 weeks after discontinuation of posaconazole-initiated antifungal therapy After discontinuation of posaconazole-initiated antifungal therapy , the related therapy options will be analyzed and the investigators will do some recommmendations for the discontinuation of IPA treatment.
The value of immune factors (IL-1β/IL-2/IL-4/IL-5/IL-6/IL-8/IL-10/IL-12/IL-17/IFN-α/IFN-γ/TNF-α) and cells (the count of neutrophil and lymphocytes) from the beginning of posaconazole-initiated treatment to 12 weeks after discontinuation of posaconazole-initiated antifungal therapy The blood RT、neutrophil function、lymphocyte count/function 、cytokine (IL-1β/IL-2/IL-4/IL-5/IL-6/IL-8/IL-10/IL-12/IL-17/IFN-α/IFN-γ/TNF-α) will be recorded and analysed at the beginning of the posaconazole-initiated treatment and 2/4/8/12 weeks after discontinuation of treatment.
The trend of immune factors (IL-1β/IL-2/IL-4/IL-5/IL-6/IL-8/IL-10/IL-12/IL-17/IFN-α/IFN-γ/TNF-α) and cells (the count of neutrophil and lymphocytes) from the beginning of posaconazole-initiated treatment to 12 weeks after discontinuation of posaconazole-initiated antifungal therapy The blood RT、neutrophil function、lymphocyte count/function 、cytokine (IL-1β/IL-2/IL-4/IL-5/IL-6/IL-8/IL-10/IL-12/IL-17/IFN-α/IFN-γ/TNF-α) will be recorded and analysed at the beginning of the posaconazole-initiated treatment and 2/4/8/12 weeks after discontinuation of treatment.
