INTRODUCTION: Tuberculous meningitis (TBM) is the most severe form of tuberculosis. As reported in various studies, stroke is common among patients with TBM, with a prevalence of 17-54%. The present study assessed platelet dysfunction and coagulation abnormality in patients with TBM.
METHODS: This was a prospective observational study that included 123 consecutive patients with TBM. In addition to clinical and radiological parameters, the complete platelet function and coagulation function were studied. The patients were followed up to 6 months.
RESULTS: A significant correlation between platelet abnormality and stroke in patients with TBM was reported in this study. Results of the univariate analysis revealed that haematological parameters such as mean platelet volume (MPV) (p < 0.001), platelet distribution width (PDW)(p < 0.001), platelet-large cell ratio (P-LCR) (p < 0.001), and platelet aggregometry (PAg) (p < 0.001) were significantly associated with infarct. However, other haematological parameters such as bleeding time (p = 0.712), clotting time (p = 0.362), activated partial thromboplastin time (p = 0.094), INR (p = 0.420), protein C (p = 0.988), and protein S (p = 0.579) were not significantly associated with infarct. During follow-up at 3 and 6 months, parameters such as MPV (p < 0.001), PDW (p < 0.001), and P-LCR (p < 0.001) were significantly associated with infarct.
CONCLUSION: The present study concluded that platelet abnormalities in patients with TBM contribute to infarct and are associated with poor clinical outcomes. This study suggested the role of antiplatelet agents in preventing stroke in patients with TBM.
