Abstract
Central nervous system tuberculosis (CNS-TB) is a severe form of extra-pulmonary tuberculosis with high mortality and morbidity rates. The standard treatment regimen for CNS-TB parallels that of pulmonary TB, despite the challenge posed by the blood-brain barrier (BBB), which limits the efficacy of first-line anti-TB drugs (ATDs). Nose-to-brain (N2B) drug delivery offers a promising solution for achieving high ATD concentrations directly at infection sites in the brain while bypassing the BBB. This study aimed to develop chitosan nanoparticles encapsulating ATDs, specifically isoniazid (INH) and rifampicin (RIF). These nanoparticles were further processed into micro-sized chitosan nano-aggregates (NA) via spray drying. Both INH-NA and RIF-NA showed strong mucoadhesion and significantly higher permeation rates across RPMI 2650 cells compared to free ATDs. Intranasal administration of these NAs to TB-infected mice for four weeks resulted in a significant reduction of mycobacterial load by approximately ∼2.86 Log 10 CFU compared to the untreated group. This preclinical data highlights the efficacy of intranasal chitosan nano-aggregates in treating CNS-TB, demonstrating high therapeutic potential, and addressing brain inflammation challenges. To our knowledge, this study is the first to show nasal delivery of ATD nano-formulations for CNS-TB management.

Abstract
Tuberculous meningitis (TBM) is the most severe complication of tuberculosis (TB) and is associated with high rates of disability and mortality. Mycobacterium tuberculosis (M. tb), the infectious agent of TB, disseminates from the respiratory epithelium, breaks through the blood-brain barrier, and establishes a primary infection in the meninges. Microglia are the core of the immune network in the central nervous system (CNS) and interact with glial cells and neurons to fight against harmful pathogens and maintain homeostasis in the brain through pleiotropic functions. However, M. tb directly infects microglia and resides in them as the primary host for bacillus infections. Largely, microglial activation slows disease progression. The non-productive inflammatory response that initiates the secretion of pro-inflammatory cytokines and chemokines may be neurotoxic and aggravate tissue injuries based on damages caused by M. tb. Host-directed therapy (HDT) is an emerging strategy for modulating host immune responses against diverse diseases. Recent studies have shown that HDT can control neuroinflammation in TBM and act as an adjunct therapy to antibiotic treatment. In this review, we discuss the diverse roles of microglia in TBM and potential host-directed TB therapies that target microglia to treat TBM. We also discuss the limitations of applying each HDT and suggest a course of action for the near future.

Abstract
Introduction and importance Intraspinal tuberculoma is rare and challenging situation, which results in serious neurological dysfunctions. Case presentation This case report shows an intraspinal tuberculoma with osseous involvement in a 31-year-old male patient with subacute progressing neurologic deficit. His medical history included tuberculosis of pulmonary and intestinal 8 years previously, at which time he had been treated with intestinal obstruction operation and antituberculosis treatment. A quadruple antituberculosis treatment was carried out after admission; however, his neurological condition was steadily worsening. He underwent debulking of mass for decompression and pathological analysis revealed intraspinal tuberculoma. The patient was prescribed a 12-month course of antituberculosis therapy, and a good clinical outcome was obtained subsequently. Clinical discussion This case was treated by microsurgical resection and antituberculosis therapy, and the outcome was favourable. Conclusion Intraspinal tuberculoma should be considered when an intraspinal mass is found with a history of tuberculosis, it can be effectively diagnosed by MRI and treated by the combination of medical and surgical treatments.

Abstract
Vasculitis is a complication of several infectious diseases affecting the central nervous system, which may result in ischemic and/or hemorrhagic stroke, transient ischemic attack, and aneurysm formation. Infectious agents may directly infect the endothelium causing vasculitis or indirectly affect the vessel wall through an immunological cascade. Clinical manifestations usually overlap with those of noninfectious vascular diseases, making diagnosis challenging. Neuroimaging enables the identification of inflammatory changes in intracranial vasculitis. In this article, we review the imaging features of infectious vasculitis of bacterial, viral, fungal and parasitic causes.

Abstract
Tuberculosis meningitis (TBM) is essentially treated with the first-line regimen used against pulmonary tuberculosis, with a prolonged continuation phase. However, clinical outcomes are poor in comparison, for reasons that are only partially understood, highlighting the need for improved preclinical tools to measure drug distribution and activity at the site of disease. A predictive animal model of TBM would also be of great value to prioritize promising drug regimens to be tested in clinical trials, given the healthy state of the development pipeline for the first time in decades. Here, we report the optimization of a rabbit model of TBM disease induced via inoculation of Mycobacterium tuberculosis into the cisterna magna, recapitulating features typical of clinical TBM: neurological deterioration within months post-infection, acid-fast bacilli in necrotic lesions in the brain and spinal cord, and elevated lactate levels in cerebrospinal fluid (CSF). None of the infected rabbits recovered or controlled the disease. We used young adult rabbits, the size of which allows for spatial drug quantitation in critical compartments of the central nervous system that cannot be collected in clinical studies. To illustrate the translational value of the model, we report the penetration of linezolid from plasma into the CSF, meninges, anatomically distinct brain areas, cervical spine, and lumbar spine. Across animals, we measured the bacterial burden concomitant with neurological deterioration, offering a useful readout for drug efficacy studies. The model thus forms the basis for building a preclinical platform to identify improved regimens and inform clinical trial design.

Abstract
INTRODUCTION Central nervous system tuberculosis (CNSTB) is a severe condition, sometimes associated with a poor prognosis. Early diagnosis of CNSTB remains challenging, considering that conventional methods lack sensitivity or might lead to certain side effects. Herein, we presented a protocol for a systematic review and meta-analysis to assess the diagnostic efficacy of MRI for CNSTB. METHODS AND ANALYSIS SinoMed, Wanfang database, China National Knowledge Infrastructure, Embase, the Cochrane Library and PubMed will be searched to identify studies reporting on the use of MRI in the diagnosis of CNSTB from database inception to December 2023. The following keywords will be applied: 'Intracranial tuberculosis', 'Cerebral tuberculosis', 'Central nervous system tuberculosis', 'Spinal tuberculous arachnoiditis' and 'Magnetic Resonance Imaging'. Studies that evaluate the diagnostic accuracy of MRI for the diagnosis of CNSTB and report clear reference criteria will be included. Studies from which full true positive, false positive, false negative and true negative values cannot be extracted, those published in languages other than English or Chinese, abstracts not reporting the full text, and case reports will be excluded. Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) will be used to evaluate the methodological quality of each included study. Stata V.15.0 and RevMan V.5.3 will be used to perform a meta-analysis and generate forest plots and summary receiver operating characteristic curves. In case of significant heterogeneity between studies, possible sources of heterogeneity will be explored through subgroup and meta-regression analyses. ETHICS AND DISSEMINATION This research is based on public databases and does not require ethical approval. Results will be submitted for publication in a peer-reviewed journal.

Abstract
Background: This research aimed to explore the possible relationship between the main experimental parameters and clinical status in meningitis patients with pneumonia infection. Methods: A retrospective analysis of the demographic characteristics, clinical features and laboratory parameters of meningitis patients was performed. Results: D-dimer, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) exhibited good diagnostic ability for meningitis complicated with pneumonia. Additionally, we observed a positive correlation between D-dimer and CRP in cases of meningitis with pneumonia infection. D-dimer, ESR and Streptococcus pneumoniae (S. pneumoniae) were independently associated with meningitis patients with pneumonia infection. Conclusion: D-dimer, CRP, ESR and S. pneumoniae infection may effectively anticipate disease progression and adverse consequences in meningitis patients with pneumonia infection.

Abstract
Central nervous system tuberculosis (CNS-TB) is rarely suspected in pregnancy because its clinical presentation may masquerade other common conditions in pregnancy, such as eclampsia. In high tuberculosis endemic areas, CNS-TB should be suspected with a high degree of suspicion among unimmunized and immunocompromised individuals. We hereby report a case of a 32-year-old pregnant woman conceived by in vitro fertilization due to tubal blockage causing infertility, probably due to chronic infection, who presented with a history of multiple seizure episodes without a history of similar complaints outside this pregnancy. Obstetric examination revealed a gravid uterus larger than the corresponding gestational age, and an antenatal scan confirmed dichorionic diamniotic twins with the first twin in the breech and the second twin in the cephalic presentation. Magnetic resonance imaging of the brain revealed multiple nodular lesions of varying sizes that were isointense on T1-weighted imaging and hypointense on T2-weighted imaging in multiple regions of the brain, which suggest tuberculomas. A preterm cesarean section was performed at 31 weeks gestational age due to preterm rupture of membranes. We report this case to enlighten the physicians in diagnosing seizures causing intracranial tuberculoma in pregnant women and utilizing the role of imaging in diagnosis.

Abstract
Central nervous system tuberculosis (CNSTB) is the most fatal type of tuberculosis (TB). Early administration of glucocorticoids can improve the prognosis of CNSTB patients and reduce mortality; however, some CNSTB patients do not respond well to anti-tuberculosis drugs and glucocorticoids. As an immunomodulatory drug, Thalidomide has been used under such circumstances. We retrospectively reviewed the drug to describe its clinical characteristics, efficacy, and safety in the treatment of four complicated CNSTB patients who responded well to thalidomide. Thalidomide may be an effective and well-tolerated drug for the treatment of CNSTB, and therefore requires further study.

Abstract
Background and PurposeIntraspinal tuberculoma is a rare disease in children, and its imaging findings have been described in only a few case reports. This study aimed to investigate the magnetic resonance imaging (MRI) features of pediatric intraspinal tuberculoma and to explore the possible pathogenesis of the disease.Materials and MethodsThe clinical and MRI data of 24 child patients with intraspinal tuberculoma (such as 6 cases of intramedullary tuberculoma, 8 cases of intradural extramedullary tuberculoma, and 10 cases of epidural tuberculoma) were retrospectively analyzed. All patients underwent plain and contrast-enhanced MR scans. The diagnosis was confirmed by surgical pathology or by antituberculous treatment and follow-up data.ResultsIntramedullary tuberculoma had a round shape, while intradural extramedullary tuberculoma and epidural tuberculoma presented long-fusiform or en plaque shapes. Regarding MRI signals, intramedullary tuberculoma and extramedullary tuberculoma were mainly isointense on T1-weighted imaging (T1WI) and hypointense or isointense on T2WI. Rim enhancement was observed in intramedullary tuberculoma, and marked homogeneous enhancement was dominant in extramedullary tuberculoma. Ten (10/24) tuberculomas occurred during antituberculous therapy, with intradural extramedullary tuberculoma accounting for 7 cases (7/8), which was significantly more frequent than intramedullary tuberculoma (1/6) or epidural tuberculoma (2/10).ConclusionMRI is important in the diagnosis of intraspinal tuberculoma, which is characterized by isointensity on T1WI, isointensity, or hypointensity on T2WI, and rim or obvious homogeneous enhancement. Some intraspinal tuberculomas, especially intradural extramedullary tuberculomas, might be associated with the “paradoxical response” mechanism during the tuberculosis treatment.

Abstract
BACKGROUND Intracranial tuberculoma is a rare and serious type of tuberculosis, which mostly occurs in the frontoparietal and cerebellar hemispheres, with predominance in the gray-white matter junction area, while tuberculomas only in the cistern are extremely rare with only a few reported cases in the literature. We describe a unique case of isolated tuberculoma in the suprasellar cistern, with only right ocular motility disorder and upper eyelid ptosis.
CASE SUMMARY A 5-year-old boy without any medical history presented with right ocular motility disorder and upper eyelid ptosis one month ago. He had no history of fever, headache, vomiting, convulsions, or limb weakness. Neurological examination showed right third cranial nerve palsy with restrictions of eye movements and ptosis, pupil dilation and negative light reflex. Imaging suggested a space-occupying lesion in the suprasellar cistern with calcification and ring-enhancement. Moreover, no Mycobacterium tuberculosis was found in cerebrospinal fluid by polymerase chain reaction (PCR). The lesion was initially diagnosed as a tumor, while postoperative pathology combined with PCR indicated tuberculoma. The patient continued postoperative anti-tuberculosis treatment. At present, the patient's condition is stable and the symptoms are partially relieved compared with those before surgery.
CONCLUSION This case confirmed that isolated intracranial tuberculoma can occur in the suprasellar cistern. Therefore, for space-occupying lesions in the suprasellar cistern, tuberculoma should be included in the differential diagnosis even if there is no history or indication of tuberculosis infection.

Abstract
AIMS A high proportion of all tuberculosis (TB) cases present with extrapulmonary tuberculosis (EPTB), including concurrent EPTB involving more than one extrapulmonary lesion site within the body. However, previous reports only characterised lesions of single-site EPTB cases. This study aimed to investigate epidemiological characteristics and association rules of concurrent EPTB cases in China. METHODS An observational multi-centre study was carried out in China from Jan 2011 to Dec 2017 that included a total of 208,214 patients with EPTB lesions. Multivariable logistic regression analysis was used to identify associations between gender and age with concurrent EPTB. Association rules were analysed for significance using the Apriori algorithm. RESULTS The most prevalent form of EPTB lesion was tuberculous pleurisy (49.8%), followed by bronchial tuberculosis (14.8%) and tuberculous meningitis (7.6%). The most predominant concurrent EPTB case type was tuberculous pleurisy concurrent with tuberculous peritonitis (1.80%). Altogether 22 association rules were identified that included 20 strong association rules, among which highest confidence rates were found for tuberculous myelitis concurrent with tuberculous meningitis and sacral TB concurrent with lumbar vertebral TB. Moreover, association rules of EPTB concurrent with other EPTB types were found to vary with gender and age. The confidence rate of tuberculous myelitis concurrent with tuberculous meningitis was higher in females (83.67%) than males and highest in patients of ages 25-34 years (87.50%). CONCLUSIONS Many types of concurrent EPTB were found. Thus, greater awareness of concurrent EPTB disease characteristics is needed to ensure timely clinical diagnosis and treatment of this disease.
