The serum concentrations of some acute phase proteins were determined on admission, during treatment, at the end of treatment and at 12 months after stopping treatment in 20 patients with pulmonary tuberculosis. Measurements were also made, on admission and at the end of treatment, in 19 patients with abdominal tuberculosis, and 11 children with tuberculous meningitis. All 20 patients with pulmonary TB had quiescent disease by the end of treatment and none had a bacteriological relapse during the follow-up period of 12 months. The response to treatment was considered favourable in 18 of the 19 patients with abdominal TB, and the CSF findings had returned to normal in 9 of 11 patients with TB meningitis. There was a significant decrease with treatment in the concentrations of C-reactive protein, ceruloplasmin, haptoglobin and alpha-1-acid glycoprotein in all 3 groups of patients. While there was an increase in the concentrations of transferrin in patients with pulmonary and abdominal TB, there was a significant decrease in those with TB meningitis; alpha 2-macroglobulin did not appear to function as an acute phase reactant in any of the 3 groups. Amalgamating the findings in all 3 groups of tuberculous patients, the proportions of patients with abnormal values on admission and at the end of treatment were 62% and 14% for C-reactive protein, 78% and 50% for ceruloplasmin, 86% and 26% for haptoglobin and 92% and 6% for alpha 1-acid glycoprotein, respectively.

It is shown that the dynamics of lipid peroxidation (LPO) in patients with purulent meningitis is unspecified in character and is encountered both in meningococcal and pneumococcal infection. The level of secondary LPO products and the degree of hyperfermentemia, which are determined according to the dynamics of changes in the activity of aspartate transaminase, are objective characteristics of the severity of the patient's condition and reach maximum on the 5th day of the disease. The correlation between the dynamics of the primary LPO products and the ceruloplasmin/transferin coefficient allows the severity of the disease to be prognosticated.

40 adult patients were examined: 24 with purulent meningitis and 16 with lymphocytic meningitis. The control group consisted of 100 healthy people. In purulent meningitis patients in the 1st, 3rd, 5th, 7th, 14th and 28th day of the disease, concentrations of the following acute phase proteins were measured in serum: C-reactive protein, alpha 1-antitripsin, alpha 1-orosomucoid, alpha 2-ceruloplasmin, alpha 2-macroglobulin and alpha 2-haptoglobin. In lymphocytic meningitis patients concentrations of the above mentioned acute phase proteins were measured only in the 1st day of the disease. Usefulness of establishing alpha 2-haptoglobin, alpha 1-antitripsin, alpha 2-ceruloplasmin and particularly C-reactive protein concentrations for differential diagnosis of purulent and lymphatic meningitis was proved. Evaluation of C-reactive protein and alpha 1-antitripsin concentration kinetics proved to be fully useful for monitoring of seriousness of the course of purulent meningitis, and together with evaluation of the clinical condition of the patient it can constitute a valuable marker of effectiveness of the disease treatment.

40 adult patients were examined: 24 with purulent meningitis and 16 with lymphocytic meningitis. In the course of purulent meningitis concentrations of the following acute phase proteins were measured in the cerebrospinal fluid: C-reactive protein, alpha 1-antitripsin, alpha 1-orosomucoid, alpha 2-ceruloplasmin, alpha 2-macroglobulin and alpha 2-haptoglobin in the 1st, 3rd, 5th, 7th, 14th and 28th day of the disease. In lymphocytic meningitis patients concentrations of the above mentioned acute phase proteins were measured only in the 1st day of the disease. Full usefulness of establishing concentrations of all the above mentioned acute phase proteins within the first five days of the purulent meningitis for differential diagnosis of purulent and lymphatic meningitis was proved. Evaluation of concentration kinetics of acute phase proteins in cerebrospinal fluid for monitoring of the course of purulent meningitis is of a limited value.

Antioxidant status was investigated in children with acute bacterial meningitis and encephalitis to investigate the possible role of free radicals in children with meningitis and encephalitis. Our study included 16 children with acute bacterial meningitis, 13 with encephalitis, and 17 control subjects. Serum ceruloplasmin, uric acid, albumin, bilirubin superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) levels were studied in all subjects within 6 h of admission. There was a statistically significant difference between the groups for all parameters except for serum uric acid. All antioxidant activities except for albumin level were increased in the study groups. Albumin level was higher in the control group than those of meningitis and encephalitis groups. When the values of meningitis and encephalitis were compared, there was a statistically significant difference between the groups for serum SOD, GPx, ceruloplasmin, and albumin. In conclusion, our study showed that serum SOD, GPx, catalase, and ceruloplasmin were higher in children with acute bacterial meningitis and serum SOD, GPx, catalase, ceruloplasmin, and total bilirubin levels were increased in children with encephalitis. These findings suggest that antioxidant status was almost similar in both acute bacterial meningitis and encephalitis conditions in childhood.

The Dps-like peroxide resistance protein (Dpr) is an aerotolerance and hydrogen peroxide resistance agent found in the meningitis-associated pathogen Streptococcus suis. Dpr is believed to act by binding free intracellular iron to prevent Fenton chemistry-catalysed formation of toxic hydroxyl radicals. The crystal structure of Dpr has been determined to 1.95 A resolution. The final model has an Rcyst value of 18.5% (Rfree = 22.4%) and consists of 12 identical monomers (each of them comprising a four alpha-helix bundle) that form a hollow sphere obeying 23 symmetry. Structural features show that Dpr belongs to the Dps family of bacterial proteins. Twelve putative ferroxidase centers, each formed at the interface of neighboring monomer pairs, were identified in the Dpr structure with structural similarities to those found in other Dps family members. Dpr was crystallized in the absence of iron, hence no bound iron was found in the structure in contrast to other Dps family members. A novel metal-binding site approximately 6A from the ferroxidase centre was identified and assigned to a bound calcium ion. Two residues from the ferroxidase centre (Asp63 and Asp74) were found to be involved in calcium binding. Structural comparison with other family members revealed that Asp63 and Asp74 adopt different conformation in the Dpr structure. The structure of Dpr presented here shows potential local conformational changes that may occur during iron incorporation. A role for the metal-binding site in iron uptake is proposed.

The objective of this study was to investigate the antioxidant/oxidant status of serum and cerebrospinal fluid in children with meningismus and acute bacterial meningitis. Twenty-three children (age range, 0.75 to 9 years) with fever and meningeal signs that required analysis of the cerebrospinal fluid, but no cytologic or biochemical evidence of meningitis in their serum and cerebrospinal fluid, constituted the meningismus group. Thirty-one children (age range, 0.5 to 10 years) with acute bacterial meningitis constituted the meningitis group. Twenty-nine healthy children (age range, 0.5 to 11 years) were recruited as control subjects. Antioxidant status (ascorbic acid, albumin, thiol, uric acid, total bilirubin, total antioxidant capacity, catalase and ceruloplasmin concentrations) and oxidant status (lipid hydroperoxide and total oxidant status) were measured. The serum antioxidant status was lower, and oxidant status levels higher in both meningitis and meningismus subjects than in the control children (P < 0.001). Cerebrospinal fluid oxidant status was lower in the meningitis group than in the meningismus group (P < 0.05). These results indicate that serum antioxidant status was lower, and serum oxidant status was higher in children in the meningismus and meningitis groups, whereas cerebrospinal fluid oxidant status was higher in the meningismus group than in the meningitis group.

Glucocorticoids are potent regulators of the innate immune response, and alteration in this inhibitory feedback has detrimental consequences for the neural tissue. This study profiled and investigated functionally candidate genes mediating this switch between cell survival and death during an acute inflammatory reaction subsequent to the absence of glucocorticoid signaling. Oligonucleotide microarray analysis revealed that following lipopolysaccharide (LPS) intracerebral administration at striatum level, more modulated genes presented transcription impairment than exacerbation upon glucocorticoid receptor blockage. Among impaired genes we identified ceruloplasmin (Cp), which plays a key role in iron metabolism and is implicated in a neurodegenative disease. Microglial and endothelial induction of Cp is a natural neuroprotective mechanism during inflammation, because Cp-deficient mice exhibited increased iron accumulation and demyelination when exposed to LPS and neurovascular reactivity to pneumococcal meningitis. This study has identified genes that can play a critical role in programming the innate immune response, helping to clarify the mechanisms leading to protection or damage during inflammatory conditions in the CNS.

The aim of this study was to assess the effects of meningitis treatment on the serum and cerebrospinal-fluid oxidant and antioxidant status in children with bacterial meningitis. Forty children with bacterial meningitis, at ages ranging from 4 months to 12 years (mean age, 4 years), were enrolled in the study. Within 8 hours after admission (before treatment) and 10 days after clinical and laboratory indications of recovery (after treatment), cerebrospinal fluid and venous blood were collected. Thirty-seven healthy children (mean age, 4 years) were enrolled as control subjects, and only venous blood was collected. Serum total oxidant status, lipid hydroperoxide, oxidative stress index, uric acid, albumin, and ceruloplasmin levels were lower in the patient group after treatment (P<0.05). Serum total antioxidant capacity levels, vitamin C, total bilirubin, and catalase concentrations were not significantly altered by treatment (P>0.05). However, cerebrospinal fluid total oxidant status, lipid hydroperoxide, and oxidative stress index levels were higher, and cerebrospinal fluid total antioxidant capacity levels were lower after treatment than before treatment (P<0.05). In conclusion, we demonstrated that serum oxidative stress was lower, and cerebrospinal fluid oxidative stress was higher, after rather than before treatment in children with bacterial meningitis.

Oxidative stress is implicated in the etiopathogenesis of a variety of human diseases. Therefore, in the present study, erythrocyte lipid peroxidation, percentage hemolysis, antioxidant enzymes viz., glutathione reductase, glutathione peroxidase, superoxide dismutase and plasma antioxidants viz., ceruloplasmin, vitamins A,E and C have been determined in 19 patients with tubercular meningitis (TBM) and 50 normals. Six patients who were treated with antibiotics were considered for the follow up. The statistical analysis was carried out by Mann Whitney U test and Wilcoxon rank sum test. Lipid peroxidation (P<0.02), percentage hemolysis (P<0.001) and plasma ceruloplasmin (P<0.0001) of TBM patients were significantly higher, whereas erythrocyte glutathione reductase (P<0.05) and plasma antioxidant vitamins A, E and C (P<0.01, P<0.05 respectively) were significantly lower than those of the controls. In the follow up patients the glutathione reductase and catalase levels were significantly high (P<0.05) compared to their pre-treated condition. Vitamin C and E levels have attained normal range. This study indicated that the blood antioxidant status of TBM patients which was low compared to controls improved after treatment, suggesting the role of free radicals in TBM.
