Background:

One third of the world’s population is thought to have latent disease (LTB) caused by infection with Mycobacterium tuberculosis (MTB). Diabetes causes a change in immune activation genes and is thought to result in unfavourable outcomes in tuberculosis (TB). We investigated the impact of LTB on DM cases in a TB endemic region using a host blood transcriptome approach.

Methods:

We studied host blood transcriptome analysis in healthy endemic controls (EC), those with latent TB (LTB), diabetic individuals (DM) and DM with LTB using the Clariom S Array 21,448 gene set, Affymetrix. Cellular pathway analysis of significant differentially expressed genes (DEGs) up- or down-regulated (log FC (fold change) < -2 or > 2; FDR adjusted P value xtagstartz0.05) were identified using anova test.
