The level of tumor necrosis factor (TNF)-alpha, soluble TNF receptors p75 (sTNFR-75) and sTNFR-55, interferon (IFN)-gamma, and interleukin (IL)-10 and IL-12 were measured in 59 cerebrospinal fluid (CSF) samples from 15 patients with tuberculous meningitis (TBM). TBM was associated with elevated concentrations of TNF-alpha, sTNFR-75, sTNFR-55, IFN-gamma, and IL-10, while CSF IL-12 was undetectable in all TBM patients. A significant correlation between cytokines and CSF adenosine deaminase activity was also found. The levels of TNF-alpha did not decrease over time, being still detectable in the CSF 16 months after starting antibiotic therapy, whereas IFN-gamma along with anti-inflammatory mediators sTNFR-75, sTNFR-55, and IL-10 remained elevated in the CSF for 4-8 months. The chronic release of cytokines in the CSF compartment was related neither to the TBM stage nor to the clinical outcome of the disease, thus suggesting the presence of a continuous activity of the inflammatory process at the site of infection.

Abstract
The level of tumor necrosis factor (TNF)-alpha, soluble TNF receptors p75 (sTNFR-75) and sTNFR-55, interferon (IFN)-gamma, and interleukin (IL)-10 and IL-12 were measured in 59 cerebrospinal fluid (CSF) samples from 15 patients with tuberculous meningitis (TBM). TBM was associated with elevated concentrations of TNF-alpha, sTNFR-75, sTNFR-55, IFN-gamma, and IL-10, while CSF IL-12 was undetectable in all TBM patients. A significant correlation between cytokines and CSF adenosine deaminase activity was also found. The levels of TNF-alpha did not decrease over time, being still detectable in the CSF 16 months after starting antibiotic therapy, whereas IFN-gamma along with anti-inflammatory mediators sTNFR-75, sTNFR-55, and IL-10 remained elevated in the CSF for 4-8 months. The chronic release of cytokines in the CSF compartment was related neither to the TBM stage nor to the clinical outcome of the disease, thus suggesting the presence of a continuous activity of the inflammatory process at the site of infection.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
