ABSTRACT
The development of tuberculoma is a process of inflammation, necrosis, and apoptosis. Therefore, the pro-inflammatory cytokines and apoptosis biomarkers are likely to play an important role. In this study, we report the expression of TNFα, IL6, and caspase-3 at the mRNA level in the patients with tuberculous meningitis (TBM) and compare these biomarkers in the patients with and without tuberculoma. A total of 134 patients with TBM and 35 matched healthy controls were included. The clinical, cerebrospinal fluid (CSF), and cranial magnetic resonance imaging (MRI) findings were noted. The mRNA expression of TNFα, IL6, and caspase-3 in peripheral blood mononuclear cells was evaluated by reverse transcriptase polymerase chain reaction. On cranial MRI, 89 (64.2%) patients had tuberculoma, and their level of consciousness, severity of meningitis, CSF findings, and blood counts were not significantly different from those without tuberculoma. Patients with tuberculoma had a higher expression of TNFα and IL6 compared to the controls, but had lower expression compared to the patients without tuberculoma. TNFα expression positively correlated with the expression of caspase-3, but not with IL6. Twenty-five (18.6%) patients died 12 (13.5%) in tuberculoma and 13 (28.9%) in the non-tuberculoma group. Death was related to higher expression of TNFα and caspase-3. The lower expression of TNFα and IL6 in intracranial tuberculoma suggests that these patients are unlikely to be benefited with TNFα blockers.
