简要总结
The aim of this study is to determine the proportion of clinical improvement, the score changing of type 1 interferon selected gene expression, and analysis of transcriptomics profiling in patients with idiopathic uveitis positive IGRA before and after receiving Anti-Tuberculosis Therapy (ATT).
Hopefully, by conducting this research, we are able to provide valid data that demonstrate the advantages/disadvantages usage of Anti-Tuberculosis Therapy in patients with idiopathic uveitis IGRA positive that correlate with type I IFN. This research is a part of our efforts in discovering bio-marker candidates of idiopathic uveitis IGRA positive clinical patients who will benefit from the ATT administration.
详细描述
Diagnostic of Idiopathic Uveitis IGRA Positive patients were still unclear. This situation happens because it is still can't be explained if the uveitis from the patients was caused by mycobacterium tuberculosis or not which leads to doubtfulness for Anti-Tuberculosis Treatment (ATT). This study aims to help to provide evidence on whether ATT usage for Idiopathic Uveitis IGRA Positive would bring beneficial impact for the patients. This study will try to analyze the data from clinical improvements, Type 1 Interferon changes, and transcriptomics analysis from the patients.

研究组 & 干预措施
Observational cohort group
Subjects: idiopathic uveitis with IGRA positive.
Examinations:
- Clinical improvement examinations at day 0, second week, week 8, month 3, month 6 and month 12.
- Blood sampling at day 0, second week, month 6 for analysing type 1 IFN gene expression scoring using RT-qPCR methods.
干预措施: Fixed drug combination (FDC) of ATT and Oral steroid (Drug)
结局指标
主要结局
Proportion of clinical improvement
时间窗: 0, 14 days, 8 weeks, 3 months, 6 months, and 12 months
Clinical improvement of uveitis patients with IGRA positive after receiving complete Anti Tuberculosis Therapy is measured by using The Standardization of Uveitis Nomenclature (SUN) inflammation degree. Clinical improvement definition is decreasing of inflammation degree up to two degrees or becoming 0 degree. Meanwhile, clinical failure is defined by increasing of inflammation degree or decreasing of inflammation degree up to one degree/ not becoming 0 degree or unchanged degree of first to fourth degree.
The changes of type 1 interferon scoring in selected gene expression
时间窗: 0, 14 days, 6 months.
The score changes of type 1 interferon of uveitis patients with IGRA positive are determined by gene expression value of 10 varieties of type 1 interferon using Quantitative Reverse Transcriptase PCR (RT-qPCR) testing.
