Abstract

Background: Tuberculosis meningitis (TBM) is the lethal and disabling form of tuberculosis, resulting in increased death and disability rates. The expression of the Leukotriene A4 Hydrolase (LTA4H) gene in TBM helps in the inflammatory pathogenesis of the disease.

Aim: This study aimed to investigate the expression of the LTA4H gene and its association with TBM in the North Indian population.

Methods: This Case-control study was conducted in the Department of Respiratory Medicine in collaboration with the Department of Biochemistry at KGMU, Lucknow, which includes 50 TBM cases and 50 control. LTA4H gene expression was analyzed by using quantitative(q) RT-PCR.

Result: No significant difference in age and gender between case and control group showed adequate (p = 0.61 and p = 0.41). The expression of LTA4H was twofold higher in TBM patients as compared to the control (p < 0.002). White blood cells were elevated in TBM patients as compared to control (19.2 ± 15.7 vs. 8.7 ± 4.2, p <0.0001). LTA4H expression was positively correlated with white blood cells (r = 0.389, p = 0.022) and negatively correlated with aspartate transaminase (r = -0.300, p = 0.038).

Conclusion: The elevated expression of LTA4H mRNA expression is associated with TBM via controlling the inflammation.

Keywords: LTA4H Gene; q-PCR; TBM.
