Inflammation-mediated changes in haemostatic variables of pulmonary tuberculosis patients during treatment

Tuberculosis (TB) disease is usually marked by inflammation which is closely linked to haemostasis both in health and disease. Close monitoring of haemostatic response to inflammatory changes during treatment is important to improve TB management. Here we studied associations between haemostatic markers and inflammatory cytokines in 60 TB-infected individuals, aged 18–65 years who received anti-TB therapy. They were recruited before commencement of therapy and followed up till completion of therapy after 6-months. The TNF-α, IL-6, IL-2 (pro-inflammatory cytokines) and P-selectin, GP IIb/IIIa, thrombopoietin (haemostatic variables) were significantly increased at 2 month into therapy compared to pre-treatment values and decreased at 6 month into therapy. Also at 6 month into therapy in comparison to 2-month into therapy, there were significant increase in IL-10 and TGF-β (anti-inflammatory cytokines) as well as a significant decline in PF-4. There were significant positive correlations between GP IIb/IIIa and TNF-α, IL-6 and PSEL, IL-6 and TPO, PF4 and TGF-β. Conclusively, the changes in the TNF-α, IL-6, IL-2 aligned with changes in the levels of P-selectin, GP IIb/IIIa, and TPO in the course of TB therapy. This may suggest that the levels of inflammatory cytokines are linked to the levels of these haemostatic variables in TB individuals.
