Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aimed to discover the composition on the microbiome in several sites of the human body; and to find out the difference in microbiome composition on ocular fluid, blood, and feces before and after therapy in uveitis patient with history of autoimmune disease (Behcet and Vogt-Koyanagi-Harada) and idiopathic uveitis

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
