Micro RNA as Prediction and/or Prognostic Markers of IRIS in TB-HIV

Status Recruiting

Clinical Trial Summary

The role of miRNAs in HIV disease is yet to be completely defined. Host miRNAs target certain HIV genes, thus can affect HIV replication and participate in viral control. miRNAs can also block HIV production through disruption of Gag assembly on cell membranes. miRNA expression can characterize HIV disease phenotype, as has been shown in HIV elite controllers who have a well-defined miRNA expression profile. However, the studies of miRNA in acute infection and co-infections like tuberculosis are lacking. The investigators showed that during immune reconstitution syndrome (IRIS) in HIV/TB coinfected patients, innate immune response play a role as through NK cell degranulation, therefore testing for this could be used as a predictive marker of IRIS.

One of the limitations of miRNA detection is the technique, which is time-consuming, and needs laboratories that are specialized and equipped for molecular biology techniques. In contrast, flow cytometry has been developed in routine labs and has well-standardized techniques. For the routine detection of miRNA, flow cytometry could be the best way to perform high throughput screening for clinical applications.

Flow cytometry is a simple and effective way to evaluate miRNAs expression. In this project the investigators propose to evaluate, using flow cytometry, whether circulating miRNA pattern might be applicable as potential biomarkers in prediction and prognosis of IRIS in HIV/TB co-infected patients. The investigators propose to study the miRNA expression profile in a cohort of patients with a HIV infection and Tuberculosis and correlate it with their clinical evolution. As controls, the investigators propose to analyze expression of miRNAs in healthy controls as well as TB and HIV mono-infected patients.

AIMS OF THE PROPOSAL

1. Identify miRNA expression profile as potential novel predictive and prognostic biomarkers for IRIS.

2. Identify the miRNA expression profile in HIV patients, in TB patients and in HIV/TB co-infected patients.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
