The radioactive 82Br partition test was performed on 83 children with suspected tuberculous meningitis. Three of 51 patients with a final diagnosis of TBM had a false negative serum to CSF bromide partition ratio of more than 1.6. Four of the 32 patients in whom TBM was excluded had a false positive ratio of less than 1.6; three of these had sever purulent bacterial meningitis. The test distinguishes TBM from viral meningitis. Antituberculous therapy does not affect the diagnostic value of the bromide partition test in the first few weeks of treatment of TBM.

We presented atypical manifestations in tuberculous meningitis (TbM) and herpes simplex encephalitis (HSE), lymphocytic dominant cerebrospinal fluid pleocytosis in bacterial meningitis, and a hitherto easily overlooked critical illness polyneuropathy (CIP) associated with sepsis. 1) We presented 2 TbM patients with atypical manifestations. One patient was a 25-year-old man who exhibited polymorphonuclear (PMN) dominant pleocytosis in CSF throughout his clinical course. He died the next day after a CSF culture yielded the growth of tuberculous bacilli, before receiving appropriate anti-TBM therapy. This was a rare TbM example of persistent PMN dominant CSF pleocytosis. The other patient was a 39-year-old woman whose CSF pleocytosis changed from lymphocytic dominant to PMN dominant about 1 month after the initiation of antituberculous chemotherapy. This CSF change was followed by multiple cerebral infarcts due to vauculitis caused by TbM. Administration of prednisolone caused marked improvement of the patient's symptomatology. Tuberculomas appeared transiently during anti-TbM therapy, consistent with paradoxical progression of tuberculoma. 2) A few patients with HSE may show atypical CSF findings such as PMN dominant pleocytosis, absence of pleocytosis, and low sugar value. Our national survey of HSE patients showed following percentages of these atypical findings: PMN dominant pleocytosis observed in 10% of the patients in the early stage and at the time of exacerbation, no pleocytosis in 0.9% (1 patient), and low sugar value in 4%. 3) Bacterial meningitis typically causes PMN dominant CSF pleocytosis. However, Listeria meningitis (LM) may cause lymphocytic dominant pleocytosis in 30% of the patients, particularly in elderly ones. We showed one such 69-year-old patient with persistent lymphocytic dominant CSF pleocytosis throughout the clinical course. 4) CIP, septic encephalopathy and critical illness myopathy are 3 major complications associated with sepsis. CIP is a frequent cause of neuromuscular weakness due to axonal dysfunction, which occurs to critically ill patients with sepsis, particularly when multiple organ dysfunctions are present. We showed our CIP patient associated with acute bacterial endocarditis and multiple organ failure. We should bear in mind these atypical manifestations, and frequent and important complications associated with sepsis such as CIP, to provide appropriate management to patients with neuro-infection and sepsis.

The objective of this study was to identify independent predictor factors for diagnosis of tuberculous meningitis and develop a clinical prediction tool based upon a set of simple clinical and laboratory parameters in our local population. Clinical and laboratory features were compared in 68 patients with tuberculous meningitis and 123 cases of acute bacterial meningitis in 3 referral centres for tuberculosis in south-eastern Iran. Twenty-two clinical and laboratory features were analysed. Based on the best-fitted model a receiver operating characteristic curve with the highest surface under the curve was constructed. Disease duration before diagnosis (>or=5 d) had the highest odds ratio of 21.9. Age over 30 y, CSF leukocyte count <or=1000 x 10(3) cells/ml and CSF lymphocytosis >or=70% were placed after disease duration with odds ratios of 5.1, 3.7 and 2.6, respectively. Sensitivity, specificity and likelihood ratio for a positive test in this model were 84%, 88% and 7.4, respectively. The area under the ROC curve was 0.92. It appears that a single model can not predict TBM diagnosis in different populations. Using clinical and laboratory parameters may facilitate empirical diagnosis of TBM in endemically low income countries with limited microbiological diagnostic facilities.

Blood-brain barrier (BBB) function and cerebrospinal fluid (CSF) biomarkers were measured in patients admitted to hospital with severe neurological infections in the Lao People's Democratic Republic (N = 66), including bacterial meningitis (BM; N = 9) or tuberculosis meningitis (TBM; N = 11), Japanese encephalitis virus (JEV; N = 25), and rickettsial infections (N = 21) including murine and scrub typhus patients. The albumin index (AI) and glial fibrillary acidic protein (GFAP) levels were significantly higher in BM and TBM than other diseases but were also raised in individual rickettsial patients. Total tau protein was significantly raised in the CSF of JEV patients. No differences were found between clinical or neurological symptoms, AI, or biomarker levels that allowed distinction between severe neurological involvement by Orientia tsutsugamushi compared with Rickettsia species.
