Abstract
We made a bacteriological diagnosis of tuberculous meningitis in 107 of 132 (81%) adults with clinical tuberculous meningitis: acid-fast bacilli were seen in 77 of 132 (58%) and cultured from 94 of 132 (71%). Volume of cerebrospinal fluid, duration of symptoms, cerebrospinal fluid neutrophils, lactate, and glucose were all independently associated with bacteriological confirmation.

Abstract
The pathogenesis of tuberculous meningitis remains unclear, and there are few data describing the kinetics of the immune response during the course of its treatment. We measured concentrations of pro- and anti-inflammatory cytokines in serial blood and cerebrospinal fluid (CSF) samples from 21 adults who were being treated for tuberculous meningitis. CSF concentrations of soluble tumor necrosis factor-alpha receptors and of matrix metalloprotein-9 and its tissue inhibitor were also measured, and blood-brain barrier permeability was assessed by the albumin and IgG partition indices. CSF concentrations of lactate, interleukin-8, and interferon-gamma were high before treatment and then decreased rapidly with antituberculosis chemotherapy. However, significant immune activation and blood-brain barrier dysfunction were still apparent after 60 days of treatment. Death was associated with high initial CSF concentrations of lactate, low numbers of white blood cells, in particular neutrophils, and low CSF glucose levels.

Abstract
Tuberculosis (TB) kills 2 million people each year in the world, of which 250,000 are children. In Italy, paediatric TB is 3.5% of total cases with a steady trend in the last ten years. Childhood tuberculosis remains a disease of great concern because its occurrence always indicates recent transmission and is a pivotal indicator of effectiveness of TB control efforts. The epidemiological study, including DNA fingerprinting, of 71 children affected by TB - 62 pulmonary, 9 meningitis, 2 renal- shows that the source case is frequently a parent or household member. Sensitivity to anti-tubercular drugs was tested for 18/20 isolates obtained from the children and 21/44 isolates obtained from infection sources with 5 resistant strains in each group. One child was resistant to isoniazid, and one adult source to rifampin. Multi-drug resistance was observed in 8 cases: 4 children and 4 sources. In the children's case, we may use the term primary resistance as the patients have not been previously treated with the drugs. These children's treatment lasted longer, not only because their regimen had been changed, but also because of their delayed clinical-radiological response to the treatment. These data suggest that it would be opportune to re-evaluate current treatment of childhood tuberculosis, encouraging active and integrated cooperation between epidemiologists, infectious disease specialists and paediatricians.

Abstract
OBJECTIVE To compare yields of cerebrospinal fluid (CSF) studies in the diagnosis of tuberculosis meningitis (TBM). DESIGN Prospective laboratory study, Kenyatta National Hospital, Kenya. STUDY POPULATION Consecutive patients with 1) headache, neck stiffness and altered consciousness for more than 14 days, 2) above features plus evidence of tuberculosis elsewhere in the body, and 3) on standard antimeningitic drugs for one week without response, were included. Those with contraindications to lumbar puncture, confirmed causes of meningitis (except TB) and on anti-tuberculosis treatment were excluded. METHODS CSF cell counts, glucose and protein were assayed. CSF was stained on ZN, cultured on LJ and BACTEC and subjected to PCR and LCR for Mycobacterium tuberculosis DNA sequences. Positive tests for M. tuberculosis were classified as definite and the rest as probable TBM. RESULTS Fifty-eight patients with a mean age of 33.0 years were recruited. Mean CSF cell count was 71/microl and CSF lymphocyte count up 67%. Mean CFS protein and glucose were 2.10 g/l and 2.05 mmol/l, respectively. BACTEC was positive in 20 cases, LJ 12, LCR eight, and PCR and ZN one each. Twenty-six patients had definite and 32 probable TBM. Patients with definite TBM had significantly higher CSF protein, lower CSF glucose, higher CSF cell count and lower CSF lymphocytes. CONCLUSION TBM can be confirmed in half of clinically suspected cases. More sensitive tests for confirmation of TBM are required.

Abstract
The early diagnosis of tuberculous meningitis (TBM) is very important. In this study, the efficiency of the polymerase chain reaction (PCR), one of the most reliable and sensitive DNA-based assays, was compared with conventional methods (acid-fast microscopy and culture) for the detection of M. tuberculosis in cerebrospinal fluid(CSF) specimens from patients suspected of TBM. Of the 29 CSF specimens from highly-probable TBM patients (based on clinical features), 25 were positive by PCR (86.2%), whereas only one of 29 was acid-fast microscopy (AFM) positive (3.4%), and 5 out of 29 were culture-positive (17.2%). No positive results were found by AFM, culture or PCR in the non-tuberculous control group. The results of this study indicate that the application of PCR should be extremely useful in the diagnosis of TBM.

Abstract
PURPOSE Tuberculosis involving the central nervous system (CNS) is rarely observed in non immuno-compromised hosts. We report herin the various clinical, biological and radiological manifestations observed in 7 patients with CNS tuberculosis. METHODS Clinical and biological records of 7 patients with CNS tuberculosis were retrospectively studied. All patients had encephalic CT-scan and MRI in the course of the disease. RESULTS 5 women and 2 men with a mean age of 38.4 years initially initially presented with headache (n = 6), fever (n = 5), meningeal irritation (n = 3), localizing neurological signs (n = 1). Lumbar punction revealed lymphocytic meningitis (n = 6/7). Mycobacterium tuberculosis or bovis was isolated in 3 patients only. Cerebral tomodensitography or magnetic resonance imaging were initially normal in most of cases (n = 4/7), but discovered in the course of disease basilar meningitis (n = 6), hydrocephalus (n = 6), abcess or tuberculoma (n = 4). In all the patients, initiation of the treatment was complicated by clinical and/or biological deterioration, called paradoxal reaction, leading in all cases to glucocorticoid adjunction, with various final results. Indeed, 4 patients developed neurological sequelae. No patient died. CONCLUSION CNS tuberculosis is a rare disease in non immunocompromised patients whose diagnostic may be difficult due to the absence of specific clinical symptoms, negative initial radiological examination, as well as delayed and often negative bacterial isolation. Paradoxal reaction appeared to be frequent despite specific antibiotherapy and underlines the beneficial effects of addictive corticosteroids.

Abstract
Nine cases of the tuberculous meningoencephalitis in adult men and women treated in years 1993-2000 have been presented. The diagnosis was established on the basis of clinical picture and examination of the cerebrospinal fluid (CSF). Routine analysis of CSF was done, as well as the microscopic examination, biological assay, and culture on the Lowenstein-Jensena medium and using Bactec 460 TB system. Only in one case Mycobacterium tuberculosis was found in the smear of CSF stained by Ziehl-Nielsen method. In one case the biologic assay was positive and Mycobacterium tuberculosis was cultured on Lowenstein-Jensen medium. In another 4 cases the pathogen was detected by Bactec 460 TB technique. In 4 cases Mycobacterium tuberculosis was also cultured from the secretion of the respiratory tract, and in one patient urine. On chest X-ray characteristic changes for pulmonary tuberculosis were observed in 5 cases (56%). Seven patients (78%) had hydrocephalus detected on CT scan of the head. One patient died, one (11%) developed persistent complication in form of spastic paralysis of lower extremities and sphincters dysfunction. Seven patients (78%) recovered completely after the 12 months therapy with standard chemotherapeutic regimen for tuberculosis.

Abstract
UNLABELLED (i) AIM OF THE STUDY The study was carried out with the aim to evaluate a polymerase chain reaction (PCR) based on the amplication of a 169 bp DNA fragment specific for the Mycobacterium tuberculosis complex for the rapid diagnosis of tuberculous meningitis (TBM). (ii) METHODOLOGY A total of 105 CSF specimens from clinically suspected cases of TBM were studied. Clinical details of the cases and cytochemical parameters of the CSF specimens were recorded. In addition to the 105 specimens, 10 CSF specimens from cases other than TBM, 4 non-mycobacterial culture isolates (1 strain of E. coli, 1 strain of Proteus species and 2 strains of Salmonella species) and 1 sample of sterile distilled water were processed as negative controls. For positive control standard culture of Mycobacterium tuberculosis H37Rv was processed with every batch of specimens. Besides PCR, smear for AFB by the Ziehl Neelsen Carbol Fuchsin (ZNCF) and the fluoro chrome method and culture on LJ medium was also carried out. (iii) RESULTS By PCR, 31.42% specimens were found positive, whereas by conventional culture on LJ medium only 3.8% specimens were positive. Only 1.9% specimens were found to be smear positive by the fluorochrome staining method, while none was positive by the ZNCF method. The PCR results showed complete correlation with the clinical findings of the patients. (iv) CONCLUSION The PCR was found to be superior to the currently available techniques for the diagnosis of tuberculous meningitis in terms of sensitivity, specificity and rapidity and could play a critical role in the diagnosis of suspected cases.

Abstract
A total of 87 cerebrospinal fluid (CSF) samples obtained from 85 patients with suspected meningitis were examined for the presence of Mycobacterium tuberculosis by means of ligase chain reaction amplification (LCx; Abbott Laboratories). The results were compared with direct smear and culture results. Of 61 patients with pathological CSF, 9 (14.8%) were scheduled to receive treatment for tuberculous meningitis. The sensitivity of the smear and culture tests was 11.1 and 33.3%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of the LCx assay were 55.5, 100, 100 and 92.9%, respectively. The results reveal that amplification by ligase chain reaction is valuable for the diagnosis of tuberculous meningitis.

Abstract
The purpose of the present study was to determine the long-term outcome of 76 children (40 females and 36 males) diagnosed and treated with modern antituberculosis drugs. The median age of the children on admission was 29.5 months and on follow-up 9 years. Antituberculosis therapy consisted of daily isoniazid (20 mg/kg), rifampicin (20 mg/kg), ethionamide (20 mg/kg), and pyrazinamide (40 mg/kg) for 6 months. Twenty-three children received daily prednisone (2-4 mg/kg) for the first month of treatment. Raised intracranial pressure was actively monitored and treated. Patients with non-communicating hydrocephalus received ventriculo-peritoneal shunts shortly after admission while communicating hydrocephalus was treated with oral acetazolamide (100 mg/kg/day) and furosemide (1 mg/kg/day) in 3-4 divided doses. Communicating hydrocephalus that did not respond to this regimen within the first month of treatment also underwent ventriculo-peritoneal shunting. Only 20% of children were functionally completely normal at follow-up. Main areas of functional deficit were cognitive impairment (80%), poor scholastic progress (43%), and emotional disturbance (40%). Twenty-five per cent of children had evidence of motor impairment, but all could walk and only 5 of 76 children (6% of total) were unable to run. One child was blind but no child had sensori-neural deafness. It was concluded that these disabilities in children from mainly deprived socioeconomic backgrounds have serious implications for their future social, academic, and career prospects. A high index of suspicion of TBM in high tuberculosis incidence communities will help prevent the morbidity documented in this study.

Abstract
Tuberculous meningitis (TBM), the most severe form of Mycobacterium tuberculosis infection in humans, is associated with significant morbidity and mortality despite successful treatment with antituberculous drugs. This is due to the irreversible brain damage subsequent to the local inflammatory response of the host to M. tuberculosis. Corticosteroids have been used in conjunction with antituberculous therapy in an attempt to modulate the inflammatory response, but this strategy has been of limited success. Therefore, we examined whether combining antituberculous drugs with the immunomodulatory drug thalidomide or with a new thalidomide analog, immunomodulatory drug 3 (IMiD3), would be effective in reducing morbidity and mortality in an experimental rabbit model of TBM. Intracisternal inoculation of 5 x 10(4) CFU of Mycobacterium bovis Ravenel in rabbits induced progressive subacute meningitis characterized by high cerebrospinal fluid (CSF) leukocytosis, protein influx, release of tumor necrosis factor (TNF), substantial meningeal inflammation, and mortality by day 28. Treatment with antituberculous drugs or with antituberculous drugs plus thalidomide improved the clinical course of disease somewhat and increased survival to about 50%. In contrast, treatment with antituberculous drugs in combination with IMiD3 limited pathological neurologic changes and resulted in marked improvement (73%) in survival. IMiD3 treatment was also associated with reduced leukocytosis in the CSF and significantly lower levels of TNF in CSF and plasma. Histologically, the meningeal inflammation in animals treated with antituberculous drugs plus IMiD3 was considerably attenuated compared to that of the other treatment groups. These results suggest a potential role for IMiD3 in the management of TBM in patients.

Abstract
In the past neurosyphilis and tuberculosis of the nervous system were the basic clinical problems in neurology. The decrease of the incidence rate has changed the situation. However, in the last few years, especially in connection with HIV infection, the incidence has even started to increase. In Poland the epidemiological situation is not alarming, but there exists some concern connected with the epidemic of syphilis and tuberculosis in countries near the Polish eastern border. In the laboratory diagnosis of syphilis the highest specificity and sensitivity has the TPHA test. In the therapy till now the best results are obtained with megadoses of penicillin. Early diagnosis of tuberculous meningitis, what is the decisive factor for positive results of the treatment can be obtained by PCR technique for detection of DNA genome of mycobacterium. In the treatment the method of choice is the concomitant use of four antimycobacterial drugs. However, there exists the serious problem of often observed drug resistance of mycobacterium.

Abstract
The performance of integral membrane antigens (IMAs) of Mycobacterium habana TMC 5135 in detecting antimycobacterial antibodies in serum and body fluids of patients mainly of extrapulmonary tuberculosis was evaluated. The IMAs were recovered from the detergent phase during Triton X-114 treatment of the plasma membrane of M. habana. Antimycobacterial antibodies were detected by ELISA using IMAs in serum and body fluids of 42 patients and 62 control subjects. As authentic adjunct Mycobacterium tuberculosis antigens were also detected (by ELISA) in body fluids and circulating immune complexes using anti-M. tuberculosis H37Ra antibodies. Anti-M. habana IMA antibody detection increased the positivity rate from 26.% (11/42) and 10% (4/42) obtained by culture and smear microscopy, respectively, to 86% (36/42). M. tuberculosis antigens were also found in 29 out of 36 anti-M. habana IMA antibody-positive cases. Interestingly, all 11 culture-positive cases were also positive for anti-M. habana IMA antibodies. The mean antigen titres in 23 cases, positive for antigens in body fluids, were 2.34 times higher in those who were also positive for anti-IMA antibodies in serum than in those negative for these antibodies. M. habana IMAs may be promising non-tubercular candidate antigens in ELISA-based serodiagnosis of extrapulmonary tuberculosis with substantial sensitivity, specificity and safety.

Abstract
Tanned sheep erythrocytes stabilized with pyruvic aldehyde and glutaraldehyde, called double-aldehyde-stabilized cells, were used to standardize passive hemagglutination assay (PHA) for detection of antibody responses to sonicate extract of Mycobacterium tuberculosis and Cysticercus cellulosae soluble antigens. PHA was performed in the following groups of cerebrospinal fluid (CSF) samples: group I - chronic infections of the central nervous system with the possible diagnosis of tuberculous meningitis (TBM), tuberculoma and neurocysticercosis (NCC) (n=88), and group II - controls which included (a) non-infectious non-neurological conditions (n=30), (b) infectious neurological conditions (n=21) and (c) non-infectious neurological conditions (n=133). PHA could detect anti-mycobacterial antibodies at the sensitivity level of 80.76% with a specificity of 92.4% and anti-cysticercal antibodies with a sensitivity of 100% and specificity of 92.94%. However, in 6.33% (i.e. 14/221) of group I and group II (c) CSFs both anti-mycobacterial and anti-cysticercal antibodies were detected. Immunoblot analysis of CSFs derived from TBM patients reacted predominantly to 120-kDa, 96-kDa, 65-kDa, 38-kDa, 26-kDa, 23-kDa, 19-kDa and 12-14-kDa and 4-6-kDa antigens of M. tuberculosis sonicate extract (MTSE), whilst CSFs of proven NCC reacted to >110-kDa, 96-kDa, 80-kDa, 66-68-kDa, 52-kDa and 26-28-kDa antigens of porcine whole cyst sonicate extract (PCSE). On immunoblot analysis, some of the CSFs of TBM patients were PHA positive for both MTSE and PCSE showed antibody reactivity to 70-kDa and 10-kDa antigens of C. cellulosae. Similarly CSF antibody of some Guillain Barre syndrome and myeloradiculopathy patients reacted with cysticercal antigens. But per se no cross-reactivity between MTSE and anti-cysticercal antibodies and vice-versa were observed. However, findings of this study should alert laboratory personnel especially in endemic areas to be extra careful in interpretation of antibody detection results.

Abstract
A 80-year-old male visited an outpatient department of a nearby hospital complaining of fever, cough, and poor appetite on June 2000. The patient was diagnosed as bacterial pneumonia and was treated with antibiotics although specific cause could not be identified. After one month, he was hospitalized due to lack of improvement. After admission, acid-fast bacilli (AFB) was found from the bronchial washing. The patient was then transferred to our hospital. Upon admission, sputum smear examination was positive for AFB and MTB was confirmed by PCR. Therapy was initiated with INH 300 mg, RFP 450 mg, EB 1000 mg, and PZA 1000 mg, orally daily. However, on the day following the admission, he became unconscious. Brain MRI showed several small granulomas on the cortex of the bilateral anterior and temporal brain. Although AFB was not detected from the cerebrospinal fluid, tuberculous meningitis was suspected and steroid was given. Nine days after admission, the patient died due to tuberculous meningitis. The isolation of MTB had been attempted on Ogawa culture medium using patient's sputum and liquor, and it took 14 weeks to find colony growth both from sputum and liquor. In the autopsy, numerous granulomas were detected in his lung, liver, kidney, and pancreas. These findings indicate that disseminated growth of MTB occurred in vivo in spite of very slow growth of MTB in vitro.

Abstract
The results of a Dot immunobinding assay (Dot Iba) for the detection of mycobacterial antigen in the cerebrospinal fluid (CSF) of 45 patients with tuberculous meningitis (TBM) were compared with the results of a polymerase chain reaction (PCR) for the detection of Mycobacterium tuberculosis. In eight patients with culture proven TBM, Dot-Iba gave positive results, while PCR yielded positive results only in six patients. The overall sensitivities of Dot-Iba and PCR in 37 patients with culture negative (probable) TBM were 75.67% and 40.5% respectively. Dot-Iba, in contrast to PCR is a rapid and relatively easier method. More importantly, Dot-Iba is suitable for the routine application for the laboratory diagnosis of TBM and therefore best suited to laboratories in the developing world.

Abstract
Empirical antimicrobial therapy remainsjustifiable in childhood pyogenic meningitis (CPM), but the continuing efficacy in a particular setting requires periodic microbiological surveillance. It was this need that informed the present five-year retrospective study of consecutive admissions for CPM at the Emergency Paediatric Unit (EPU) of the University of Ilorin Teaching Hospital, Ilorin, Nigeria. Of the 71 cerebro-spinal fluid [CSF] analyses, 41 (57.6%) were Gram-smear positive (GSP). Gram-positive cocci (GPC) were identified in 23 (56.1%) smears, while 14 (34.2.%) had Gram-negative bacilli (GNB). Only three (7.3%) had Gram-negative diplococci (GND). Despite corroborative biochemical findings, the remaining 30 (42.3%), including two with tuberculous meningitis proved smear-negative. GPC cases had a mean age of 4.49 +/- 5.3yrs, GNB, 3.06 +/- 4.8yrs and GND, 4.47 +/- 4.9yrs. CSF isolates were made in 28 (39.4%) cases. Streptococcus pneumoniae accounted for a predominant 22 (78.6%) (P = 0.00), Haemophilus influenzae for 2 (7.1%), and Neisseria meningitidis for only 1 (3.5%) case. Whereas Strept. pneumoniae and H. influenzae isolates were uniformly sensitive to each of sultamicillin, cefuroxime, ceftriaxone and ceftazidime, 7.7% of Strept. pneumoniae were resistant to crystalline penicillin, 6.7% to ampicillin, and 69.2% to chloramphenicol; one of the two H. influenzae isolates was chloramphenicol-resistant. Amongst the 30 (42.3%) fatal cases, the length of stay was significantly shorter in GNB-positive cases (P = 0.045). Mortality was significantly higher amongst cases with purulent/turbid CSF at admission (P = 0.03), and in those with CSF protein of >150mg/dl (P = 0.02) and glucose <1mg/dl (P = 0.047). The present aetiological preponderance of GPC and Strept. pneumoniae in our study population, the high case-fatality, and the emerging resistance profile suggest the need for exploring additional control options including vaccination. We emphasize the need for periodic auditing of local antimicrobial policies in CPM.

Abstract
UNLABELLED Tuberculous meningoencephalitis (TBM), an infrequent disease in Western European countries, shows a wide heterogeneity of clinical symptoms. MATERIAL AND METHODS We present 4 patients (age range 42-72 years) with the definite diagnosis of isolated TBM. All patients were HIV-seronegative, only 1 patient was known to be immunoincompetent on admission due to acute myelocytic leukemia; other reasons for immune suppression were detected in 2 other patients (leukemia and idiopathic CD4+ T-lymphocytopenia, respectively). RESULTS The diagnosis of TBM was confirmed in 3 cases by culture from CSF, in 1 case Mycobacterium tuberculosis was proven only in tracheal aspirate. In 1 patient M. bovis was found, which is an extremely rare cause of TBM in Germany. We report the contributions of different diagnostic tools (CSF analysis, neuroimaging) in reaching the presumptive diagnosis and in monitoring the further course. All patients developed neurological complications despite prompt tuberculostatic treatment. Three of the patients presented a chronic severe loss of consciousness of unclear origin. CONCLUSION The possible causative relationships of these complications and their impact on the prognosis are discussed.

Abstract
An analysis was performed of 112 protocols of autopsies of those adult subjects having died of generalized tuberculosis presenting with tuberculous meningitis over the last 50 years. A significant pathomorphism of tuberculosis of meninges and central nervous system was found out to have taken place over that period of time. Over the last decade, reversion of generalized tuberculosis has been noted together with an increase in the incidence of tuberculous meningitis and younger age of those patients who die of grave forms of the specific process.

Abstract
OBJECTIVE To evaluate specimen processing with sodium dodecyl (lauryl) sulfate (SDS) on the detection of Mycobacterium tuberculosis by PCR-reversed dot hybridization. METHODS Totally 266 specimens were collected from sputum, pleural fluid, ascites, urine or blood of patients with active tuberculosis and were treated with SDS or routine method. All specimens handled were tested for detecting M. tuberculosis by PCR-reversed dot hybridization. RESULTS The detection rate of M. tuberculosis from specimens prepared by SDS method was 65.0% (173/266) as compared with 51.5% (136/168) by routine method. Results from two methods were considered statistically significant (chi(2) = 35.03, P < 0.001). CONCLUSION The SDS processing method may be used to detect M. tuberculosis from clinical specimens by PCR and enhances the detection rate of M. tuberculosis.

Abstract
We have evaluated a new set of primers (TRC(4)) in comparison with the IS6110 primers commonly used in PCR to detect tuberculous meningitis among children. The levels of concordance between the results of IS6110 PCR and TRC(4) PCR with cerebrospinal fluid specimens from patients with clinically confirmed tuberculous meningitis were 80 and 86%, respectively. Results with the two primer sets were concordant for 55 positive and 22 negative specimens (n = 98). We conclude that the sensitivity of PCR can be increased by using both IS6110 and TRC(4) primers.

Abstract
Tuberculous meningitis is characterized by cerebral tissue destruction. Monocytes, pivotal in immune responses to Mycobacterium tuberculosis, secrete matrix metalloproteinase-9 (MMP-9), which facilitates leukocyte migration across the blood-brain barrier, but may cause cerebral injury. In vitro, human monocytic (THP-1) cells infected by live, virulent M. tuberculosis secreted MMP-9 in a dose-dependent manner. At 24 h, MMP-9 concentrations increased 10-fold to 239 +/- 75 ng/ml (p = 0.001 vs controls). MMP-9 mRNA became detectable at 24--48 h. In contrast, tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) gene expression and secretion were similar to constitutive levels from controls at 24 h and increased just 5-fold by 48 h. In vivo investigation revealed MMP-9 concentration per leukocyte in cerebrospinal fluid (CSF) from tuberculous meningitis patients (n = 23; median (range), 3.19 (0.19--31.00) ng/ml/cell) to be higher than that in bacterial (n = 12; 0.23 (0.01--18.37) ng/ml/cell) or viral meningitis (n = 20; 0.20 (0.04--31.00) ng/ml/cell; p < 0.01). TIMP-1, which was constitutively secreted into CSF, was not elevated in tuberculous compared with bacterial meningitis or controls. Thus, a phenotype in which MMP-9 activity is relatively unrestricted by TIMP-1 developed both in vitro and in vivo. This is functionally significant, since MMP-9 concentrations per CSF leukocyte (but not TIMP-1 concentrations) were elevated in fatal tuberculous meningitis and in patients with signs of cerebral tissue damage (unconsciousness, confusion, or neurological deficit; p < 0.05). However, MMP-9 activity was unrelated to the severity of systemic illness. In summary, M. tuberculosis-infected monocytic cells develop a matrix-degrading phenotype, which was observed in vivo and relates to clinical signs reflecting cerebral injury in tuberculous meningitis.

Abstract
Mycobacterium tuberculosis is one of the most common infectious agents in the world. It causes an insidious form of meningitis characterized by headache, low-grade fever, stiff neck and cranial nerve palsies, and an acute meningoencephalitis characterized by coma, raised intracranial pressure, seizures, and focal neurological deficits. This review focuses on the diagnosis and therapy of the insidious form of tuberculous meningitis and discusses the differential diagnosis of infectious and noninfectious etiologies of the aseptic meningitis syndrome.
