Pilot Project: The Amplicon and Metatranscriptomic Study of Intra and Extra Intestinal Microbiome in Non-infectious Uveitis Disease
Pilot Project: The Amplicon and Metatranscriptomic Next-generation Sequencing of Samples From Intra and Extra-intestinal Microbiome in Non-infectious Uveitis Patients to Decipher Possibility Uveitis Pathogenesis
Study Overview

Detailed Description
Gut microbiome has been widely studied around the globe, and it is convinced that the gut microbiome plays an essential role in many human diseases. In a published review showed the presence of microbes in blood from a patient who suffered from non-communicable disease. The microbes present in dormant or not-immediately-culturable states as if blood is a 'sterile' environment. It was argued that the difficulty of culturing microbes from the blood was coming from the limited understanding of suitable growth/isolation media for the microbes to be cultured. This limitation can be overcome by the sequenced-based methods for detecting non-proliferating microbes. The presence of microbes in blood also can be observed by ultrastructural (microscopic) methods. Through the microscopic observations, it was witnessing the presence of coccus and bacillus shaped bacteria that present proximity to (Red Blood Cell) RBCs in sample blood patients with Alzheimer's or Parkinson's Disease. The presence of microbes in the places other than their normal location state by term 'atopobiosis'. The presence of microbes in blood suspected as a result of translocation between the gut to the blood.
Therefore, according to the current knowledge of microbiome association and the human diseases, we are eager to conduct a pilot project that gives a comprehensive picture of the association between the microbiome and uveitis disease partially non-infectious and idiopathic uveitis. We will investigate microbiome profiling in the intestinal and extra-intestinal of uveitis patients before and after treatment to see whether any alteration of microbial abundance at two distinct clinical conditions partially in uveitis patients with history of autoimmune disease (Behcet and Vogt-Koyanagi-Harada) and idiopathic uveitis. Another objective of this study is to explore any pathogenic microorganism that present in uveitis patients samples conducted by a sequenced-based method.

Time Frame |
---|---|---|
Differential abundant taxonomic groups bacterial
Time Frame: 0, 6 weeks
|
The primer used in this amplicon study is targeted to 16S rRNA gene region V3-V4 to detect bacterial diversity in the samples.
The sequencing will be generated by Illumina according to standard protocol.
Prior filter is conducted using Prinseq-lite, then chimeric sequences remove using Usearch61 and left over the high quality reads.
The (operational taxonomic unit) OTU is picked using bioinformatic tool (Quantitative Insights Into Microbial Ecology - QIIME).
Taxonomic classification for de novo OTUs clustering will be generated using open source software package for bioinformatics data processing.
Shanon diversity, Simpson index will be examined for calculating alpha diversity.
And then we will do identification of differential abundant taxonomic groups.
And do analysis correlation network between bacterial genera among two clinical condition (before and after received oral steroid) relatively to health control.

Time Frame |
---|---|---|
Detection pathogenic microorganism in samples
Time Frame: 0, 6 weeks
|
In this study we are going to use IDseq Portal, a novel bioinformatics platform that designed for detection of microbes from metagenomic data.
This analysis will be applied in all types samples (stool, blood, and aqueous humor).
We expect to find any specific microbiome (bacterial/fungal/virus) signature in samples patient uveitis.
