Trial Summary

What is the purpose of this trial?

This is a multi-center randomized controlled evaluator-masked trial designed to compare metagenomic deep sequencing (MDS) versus standard of care testing for improvement of outcomes for intraocular infections. Patients with presumed intraocular infections who meet the eligibility criteria will be randomized to receive MDS testing results or not to receive MDS testing results. All patients will receive standard-of-care testing to guide management. Enrolled patients will be followed at week 2, week 3-6 (randomization visit), and at 4 weeks after the randomization visit. The proportions of patients who received the appropriate therapy and the proportions of patients with improved outcome will be compared between arms. Patient quality of life, MDS performance, and the provider certainly of belief will be collected.

Do I need to stop my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Metagenomic Deep Sequencing (MDS) for intraocular infections?

Research shows that Metagenomic Deep Sequencing (MDS) can accurately detect pathogens in eye fluid samples, which helps in diagnosing infections more effectively than traditional methods.12345

Is metagenomic deep sequencing safe for humans?

The research articles focus on the effectiveness of metagenomic deep sequencing (mNGS) in diagnosing intraocular infections, but they do not provide specific safety data for humans. However, these studies do not report any safety concerns related to the use of mNGS in humans.12367

How does the treatment Metagenomic Deep Sequencing (MDS) differ from other treatments for intraocular infections?

Metagenomic Deep Sequencing (MDS) is unique because it uses advanced genetic sequencing to identify a wide range of pathogens in eye infections, which can be difficult to diagnose with traditional methods. This approach allows for a more accurate and comprehensive detection of bacteria, viruses, fungi, and parasites in intraocular fluid, potentially leading to better-targeted treatments.12389

Findings from Research

Unbiased metagenomic deep sequencing (MDS) effectively detected pathogens in intraocular fluid samples from patients with uveitis, accurately identifying known pathogens like Cryptococcus neoformans and Toxoplasma gondii, as well as a previously unknown rubella virus infection in one patient.
The study suggests that MDS can reveal chronic infections in the eye, highlighting its potential as a diagnostic tool for ocular infections that are often difficult to identify, which could improve treatment outcomes and understanding of pathogen reservoirs.
Illuminating uveitis: metagenomic deep sequencing identifies common and rare pathogens.Doan, T., Wilson, MR., Crawford, ED., et al.[2023]
In a study of 15 patients with suspected intraocular infections, metagenomic next-generation sequencing (mNGS) successfully identified pathogens in 8 samples, confirming its efficacy in diagnosing these infections.
Despite 7 samples returning negative mNGS results, 4 were still diagnosed with intraocular infections through clinical evaluation and other tests, highlighting the need for optimized mNGS protocols to better detect intracellular pathogens.
Application of metagenomic next-generation sequencing in suspected intraocular infections.Qian, Z., Zhang, Y., Wang, L., et al.[2023]
Metagenomic next-generation sequencing (mNGS) identified pathogens in 88.89% of endophthalmitis cases, significantly outperforming traditional culture methods, which only had a positive rate of 27.78%.
mNGS not only detected common pathogens like Staphylococcus epidermidis and Klebsiella pneumoniae but also revealed antibiotic resistance genes in 9 cases, highlighting its potential for improving treatment strategies and understanding visual prognosis.
