Diagnostic Value of Cerebrospinal Fluid T-SPOT.TB for Tuberculousis Meningitis in China

The aim of this study was to evaluate the diagnostic value of the cerebrospinal fluid（CSF） T‐SPOT.TB test for the diagnosis of TB meningitis（TBM）. A retrospective analysis of 96 patients with manifested meningitis was conducted; T‐SPOT.TB test was performed for diagnosing TBM to determine the diagnostic sensitivity, specificity, positive predictive value（PPV）, and negative predictive value（NPV）. A receiver operating characteristic（ROC） curve was also drawn to assess the diagnostic accuracy. The sensitivity, specificity, PPV, and NPV of CSF T‐SPOT.TB test were 97.8%, 78.0%, 80.3%, and 97.5%, respectively, for 52 patients（54.2%） of the 96 enrolled patients. The area under the curve（AUC） was 0.910, and the sensitivities of CSF T‐SPOT.TB for patients with stages I, II, and III of TBM were 96.7%, 97.2%, and 98.9%, respectively. CSF T‐SPOT.TB test is a rapid and accurate diagnostic method with higher sensitivity and specificity for diagnosing TBM.

Levels of soluble delta-like ligand 1 in the serum and cerebrospinal fluid of tuberculous meningitis patients

In this study, the levels of soluble delta-like ligand 1 in cerebmspinal fluid and serum of 50 patients with tuberculous meningitis, 30 patients with viral meningitis, 20 patients with purulent meningitis and 40 subjects without central nervous system disease were determined using an enzyme-linked immunosorbent assay. The mean levels of soluble delta-like ligand 1 in both cerebrospinal fluid and serum from patients with tuberculous meningitis were significantly higher compared with those from patients with viral meningitis or purulent meningitis or from subjects without central nervous system disease. Meanwhile, the level of soluble delta-like ligand 1 gradually decreased as tuberculous meningitis patients recovered. If patients deteriorated after treatment, the level of soluble delta-like ligand 1 in cerebrospinal fluid gradually increased. There was no correlation between the level of soluble delta-like ligand 1 and the protein level/cell number in cerebrospinal fluid. Our findings indicate that the levels of soluble delta-like ligand 1 in cerebrospinal fluid and serum are reliable markers for the diagnosis of tuberculous meningitis and for monitoring treatment progress. At the same time, this index is not influenced by protein levels or cell numbers in cerebrospinal fluid.

Changes of insulin-like growth factor-Ⅱ and insulin-like growth factor binding protein-3 in cerebrospinal fluid of children with tuberculous meningitis

BACKGROUND： Recent studies have found that insulin-like growth factors （IGFs） and insulin-like growth factor binding protein-3 （IGFBP-3） have stronger neurotrophic and neuroprotective effects. But whether their levels in cerebrospinal fluid could be used as an auxiliary indicator in differentially diagnosing tuberculous meningitis and viral encephalitis is not yet clear. OBJECTIVE： To explore the changes of insulin-like growth factor-Ⅱ （IGF-Ⅱ ） and IGFBP-3 in cerebrospinal fluid （CSF） of children with tuberculous meningitis and the significance of the changes. DESIGN： A non-randomized concurrent controlled study. SETTING： Department of Pediatric Internal Medicine, the First Affiliated Hospital of Xinxiang Medical College. PARTICIPANTS： Thirty children with tuberculous meningitis （14 males and 16 females） were selected from the Department of Pediatric Internal Medicine, the First Affiliated Hospital of Xinxiang Medical College from January 2005 to December 2006. Tuberculous meningitis was diagnosed according to their clinical manifestations, the history of close contact with tuberculosis, typical cerebrospinal fluid changes of tuberculous meningitis, positive tuberculosis antibody and effective antituberculosis treatment. There were 30 children （13 males and 17 females） with viral encephalitis, and viral encephalitis was diagnosed according to epidemiological history, clinical manifestations, conventional and biochemical changes of cerebrospinal fluid, and negative bacteriology judgment. Meanwhile, 30 children （13 males and 17 females） without infectious and central nervous system disease were selected as the control group. Informed consent was obtained from the parents of all the enrolled children. METHODS： ①The lumbar puncture operation was implemented immediately to obtain cerebrospinal fluid （3 mL）. The contents of IGF-Ⅱ and IGFBP-3 were detected with immunoradiometric assay. The concentrations of glucose and protein in cerebrospinal fluid were determined with a dry-chemical method. The number of white blood cells was counted by Fushi Method. ②The Pearson correlation analysis was used to analyze the correlation of the contents of IGF-Ⅱ and IGFBP-3 in cerebrospinal fluid with the leucocyte counting and the concentrations of glucose and protein in cerebrospinal fluid. MAIN OUTCOME MEASURES： The contents of IGF- Ⅱ and IGFBP-3 in cerebrospinal fluid, and their correlation with the leucocyte counting and the concentrations of glucose and protein in cerebrospinal fluid. RESULTS： ①Contents of IGF-Ⅱ and IGFBP-3 in cerebrospinal fluid： The contents of IGF-Ⅱ and IGFBP-3 in cerebrospinal fluid in the tuberculous meningitis group were significantly higher than those in the encephalitis virus group and control group （P 〈 0.05）. There was no significant difference in the contents of IGF- Ⅱ and IGFBP-3 in cerebrospinal fluid between the viral encephalitis group and control group （P 〉 0.05）. ②Correlation： The IGF- Ⅱ and IGFBP-3 contents in cerebrospinal fluid were positively correlated with the protein concentration in cerebrospinal fluid （r =0.821, 0.855, P 〈 0.01）, but negatively with the glucose （r =0.742, - 0.605, P 〈 0.01）. CONCLUSION- ①IGFs and IGVBPs are involved in the pathophysiological process of tuberculous meningitis, as well as the glucose and protein metabolism in cerebrospinal fluid. ②The IGF-Ⅱ and IGFBP-3 contents in cerebrospinal fluid can be used as the auxiliary indicators to differentially diagnose tuberculous meningitis and viral enceohalitis.

Tuberculous meningitis and miliary tuberculosis in Iran:A review

In recent years,the number of cases of extrapulmonary tuberculosis in Iran has increased.The goal of this study was to determine the epidemiological status,clinical symptoms,diagnostic methods,and treatment strategies of extrapulmonary tuberculosis in Iran,with a focus on tuberculosis meningitis and miliary tuberculosis.Between January 1,2000 and June 1,2021,1651 cases of tuberculosis meningitis and miliary tuberculosis were discovered in Iran.The prevalence of tuberculosis meningitis was higher in Sistan and Baluchestan,South Khorasan,and Mazandaran compared with other provinces.The most prevalent symptoms of tuberculous meningitis were fever,anorexia,headache,neck stiffness,loss of consciousness,and vomiting.The most commonly used procedures for diagnosing tuberculous meningitis were polymerase chain reaction and cerebrospinal fluid culture.The most prevalent clinical symptoms of miliary tuberculosis were fever,lethargy,weariness,and anorexia.In 70%of chest radiographs,a miliary pattern was visible.Bone marrow biopsy was used to diagnose miliary tuberculosis in 80%of patients,while bronchoalveolar lavage was used in 20%of cases.The conventional 6-month treatment approach for tuberculous meningitis and miliary tuberculosis was used for all of the participants in the investigations.Given the high prevalence of extrapulmonary tuberculosis patients in Iran and the devastating consequences of the disease,the researchers recommend that further study be done to prevent extrapulmonary tuberculosis in the general population.

Tuberculous Meningitis and COVID-19 Co-Infection: About a Case

We report the case of an adult patient diagnosed with acute SARS-CoV-2-associated meningoencephalitis based on the detection of its RNA on a nasopharyngeal swab, cerebrospinal fluid analysis. The most destructive type of extrapulmonary tuberculosis is tuberculous meningitis, in which the consequences are severe, resulting in death or disability in almost half of all sufferers despite anti-tuberculosis chemotherapy. The aim of this study was to assess the clinical and paraclinical features and laboratory findings and outcome of a patient with tuberculous meningitis and COVID-19 coinfection. Infection of COVID-19 and lymphopenia promotes the development of the severe form of tuberculosis. On the other hand, TBM increased the risk of infection with coronavirus due to the weakened immune system in addition to other immunosuppressive factors (older age and comorbidities such as low socioeconomic status and malnutrition). The patient had a good recovery even if he required intensive neurorehabilitation for a month due to poor feeding and weakness. Treatment, both anti-mycobacterial and anti-inflammatory, early started, guaranteed good recovery.

Tuberculous Meningitis: Diagnostic and Radiological Features, Pathogenesis and Biomarkers

Central nervous system tuberculosis is the most severe form of extrapulmonary tuberculosis disease. We aim to review the diagnostic and radiological features, pathogenesis, and biomarkers of tuberculous meningitis. We also aim to look at the latest development of research of the disease. The diagnosis of tuberculous (TB) meningitis is difficult because the disease presents with unspecific clinical features. However, the disease has excellent clinical response to antituberculous therapy. Good prognosis depends on prompt diagnosis with treatment and radiological findings are very important. There is an increase in the levels of serum and cerebrospinal fluid (CSF) TNF-in TB meningitis patients. IL-6 level is also increased in patients with tuberculoma and exudates. There is an increase in the levels of serum and CSF TNF-α and IFN-γ in TB meningitis patients. There is also a rise in the levels of IL-8, IFN-alpha, IFN-gamma, IL-10, CSF matrix metalloproteinases, CSF tissue inhibitors of matrix Metalloproteinases, VEGF level, caspase-1 and IL-1β. Signal-regulatory protein alpha is overexpressed at mRNA level. High dose intravenous rifampicin (800 mg daily) is associated with reduced mortality in patients with advanced disease.

Bilateral optic nerve infiltration in tuberculous meningitis: A diagnostic dilemma

Rationale:Tuberculous meningitis(TBM)is severe extrapulmonary tuberculosis that can cause poor outcomes without timely treatment.We report a case of presumed TBM that presented solely ocular complaints without other neurological features.Patient's concerns:A 71-year-old man presented with a sudden central visual defect in both eyes for 10 days.Fundoscopy showed bilateral hyperaemic swelling disc with infiltrates.Diagnosis:A diagnosis of presumptive TBM was made with Mantoux test reading 15 mm,elevated erythrocyte sedimentation rate,subdural effusion on CT scan,and high opening pressure.Intervention:Anti-tuberculous treatment.Outcomes:Bilateral vision improved and optic discs swelling resolved.Lessons:Early recognition of TBM with optic nerve infiltration is crucial for prompt treatment that may lead to a good prognosis.Neuroimaging will facilitate the diagnosis when other investigations show a borderline result.

Significance of cerebrospinal fluid and plasma biochemical indicator ratio in identifying the tuberculous meningitis and purulent meningitis

Objective:To explore the significance of cerebrospinal fluid and plasma biochemical indicator ratio in identifying the tuberculous meningitis and purulent meningitis.Methods: A total of 43 patients with tuberculous meningitis who were admitted in our hospital from August 2015 to July 2017 were included in the study and served as the tuberculous meningitis group. Moreover, 40 cases with purulent meningitis were served as the purulent meningitis group. The morning fasting peripheral venous blood was collected and centrifuged for the plasma. Lumbar puncture was used to collect cerebrospinal fluid. The fully automatic biochemical analyzer was used to detect GSH, the plasma protein, chloride, glucose, lactic acid, and ADA. GSF/plasma ratio was calculated. The immunity transmission turbidity was used to detect GSH and Cys-C. FCM was used to detect CD64. ELISA was used to detect MMP-9.Results:GSF chloride and lactic acid in the tuberculous meningitis group were significantly lower than those in the purulent meningitis group, while ADA was significantly higher than that in the purulent meningitis group. The plasma protein, chloride, and lactic acid in the tuberculous meningitis group were significantly lower than those in the purulent meningitis group, while ADA was significantly higher than that in the purulent meningitis group. ADA ratio in GSF in the tuberculous meningitis group was significantly higher than that in the purulent meningitis group, while chloride and lactic acid ratio was significantly lower than that in the purulent meningitis group. CD64 in GSF in the tuberculous meningitis group was significantly lower than that in the purulent meningitis group, and MMP-9 was significantly higher than that in the purulent meningitis group, while the comparison of Cys-C between the two groups was not statistically significant.Conclusions: GSF, plasma protein, chloride, lactic acid, and ADA concentration ratio in the tuberculous meningitis group and purulent meningitis group have a certain difference. Combined detection of CD64 and MMP-9 contribute to identifying the two meningitis.

Diagnosis of disease-specific proteins in cerebrospinal fluid of children infected with tuberculous meningitis

BACKGROUND： Isolated mycobacterium tuberculosis from cerebrospinal fluid （CSF） is regarded as the ＂gold standard＂ for diagnosis of tuberculous meningitis （TBM）. However, culture of CSF specimens is time-consuming and lacks sensitivity. There is a strong need to determine complementary disease-specific markers, which are essential for increasing early diagnosis and improving prognosis in patients with TBM OBJECTIVE： To establish proteomic profiles of CSF in TBM and normal children using two-dimensional polyacrylamide gel electrophoresis, and to screen for disease-specific proteins. DESIGN, TIME AND SETTING： The case-control study was conducted at the Department of Pediatrics, Xiangya Hospital of Central South University and the Key Laboratory of Cancer Proteomics of Ministry of Public Health of China between January 2008 and January 2009. PARTICIPANTS： The TBM group included three patients with a strongly positive tuberculin skin test, as well as positive CSF mycobacterial staining and culture, who were admitted to the Department of Pediatrics, Xiangya Hospital from January 2008 to January 2009. Three healthy, age- and gender-matched children served as the control group. METHODS： CSF proteins were separated using two-dimensional polyacrylamide gel electrophoresis in both groups. Gels were scanned using Image scanner and LabScan software. Differentially expressed proteins were analyzed using PDQuest 7.0 software. The clearly discernible spots, which were expressed only in the TBM group, were chosen to perform matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis. MAIN OUTCOME MEASURES： Differentially expressed spots on CSF profiles of TBM and normal children were measured. RESULTS： Following comparison of two-dimensional polyacrylamide gel electrophoresis maps between TBM and control groups, 546 and 533 spots were detected, respectively. A total of 64 differentially expressed proteins were observed between the groups, including 15 upregulated spots, eight downregulated spots, 27 spots that were exclusively expressed in the TBM group, and 14 spots that were exclusively expressed in the control group. At total of 20 spots that were exclusively expressed in the TBM group were chosen for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis, and 20 peptide mass fingerprints were obtained. After searching the data base, 16 proteins were matched. CONCLUSION： Two-dimensional polyacrylamide gel electrophoresis profiles of the CSF proteome were successfully established in the TBM and normal children. Parts of these differentially expressed proteins were identified through mass spectrometry and bioinformatics. Results indicated that apolipoprotein A I, anti-tumor necrosis factor-alpha antibody, crystal structure of MRP14 and HLA class II histocompatibility antigen DRB1-4 could be closely correlated with TBM pathogenesis.

Tuberculous peritonitis complicated by an intraperitoneal tuberculous abscess: A case report

BACKGROUND Tuberculous peritonitis(TBP)is a chronic,diffuse inflammation of the peritoneum caused by Mycobacterium tuberculosis.The route of infection can be by direct spread of intraperitoneal tuberculosis(TB)or by hematogenous dissemination.The former is more common,such as intestinal TB,mesenteric lymphatic TB,fa-llopian tube TB,etc.,and can be the direct primary lesion of the disease.CASE SUMMARY We present an older male patient with TBP complicated by an abdominal mass.The patient's preoperative symptoms,signs and imaging data suggested a poss-ible abdominal tumor.After surgical treatment,the patient's primary diagnosis of TBP complicating an intraperitoneal tuberculous abscess was established by com-bining past medical history,postoperative pathology,and positive results of TB-related laboratory tests.The patient's symptoms were significantly reduced after surgical treatment,and he was discharged from the hospital with instructions to continue treatment at a TB specialist hospital and to undergo anti-TB treatment if necessary.CONCLUSION This case report analyses the management of TBP complicated by intraperitoneal tuberculous abscess and highlights the importance of early definitive diagnosis in the hope of improving the clinical management of this type of disease.

Research Progress of microRNA in the Diagnosis of Tuberculous Pleurisy

Tuberculosis has become a major public health and social problem threatening human health, and a large proportion of pulmonary tuberculosis patients are associated with tuberculous pleurisy (TP). Therefore, it is of great significance to find markers with high specificity and sensitivity for the rapid and accurate diagnosis and differential diagnosis of TP under the severe background of high infectivity and mortality due to the occult nature of TP. The extraction of microRNA (miRNA) from pleural effusion satisfies the characteristics of strong operability. miRNA exists not only in cells, but also in various body fluids and participates in the pathophysiological process of various diseases including infectious diseases. miRNA is a highly specific biomarker in pleural fluid in patients with TP. Therefore, this article provides a review of the research progress of mRNA in tuberculous pleurisy.

The infant showed significant improvement following an extended course of systemic antibiotics and supportive care.

Early Nursing Intervention in Children with Viral Meningitis

Aim: To explore the effect of a WeChat peer education program in children with severe viral meningitis combined with respiratory failure. Design: Retrospective cohort study. Methods: Patients who had severe viral meningitis combined with respiratory failure, were admitted to the hospital from March 2017 to June 2018, and who received the WeChat-based nursing intervention were included. Patients who received routine nursing were used as controls. The family’s emotional state, self-care ability, and rehabilitation were analyzed. Results: There were 37 patients in the WeChat group (19 boys (51.3%) and 18 girls (48.7%);mean of 5.1 ± 2.4 years of age) and 37 controls (20 boys (54.1%) and 17 girls (45.9%);mean of 5.9 ± 2.4 years of age) (all P > 0.05). After nursing, improvements in the self-assessed anxiety score and self-assessed depression score were better in the WeChat group (anxiety: -29.2% vs. -20.3%, P = 0.015;depression: -25.2% vs. -15.4%, P = 0.009). After nursing, the improvements in the condition management ability scale and condition management difficulty scale scores were better in the WeChat group (ability: +80.5% vs. +44.4%. P = 0.001;difficulty: +58.4% vs. +37.8%, P = 0.003). After nursing, the improvement in the Fugl-Meyer score was better in the WeChat group (+138.0% vs. +53.0%, P Conclusion: Early nursing intervention combined with WeChat peer education can improve the emotional state of children with severe viral meningitis combined with respiratory failure and their caregivers. Impact: Viral meningitis is associated with a good prognosis, but central nervous system complications can be observed. Early intervention is the key to a good prognosis. Internet-based nursing and coaching can improve self-efficacy and care ability in patients with various conditions, as well as improve the emotional state of the children and their caregivers. The research might have an impact on any children’s hospital that deals with viral meningitis.

Co-infection with Neisseria mucosa in a patient with tuberculous otitis media

Tuberculous otitis media(TOM) is a rare manifestation caused by Mycobacterium tuberculosis with low incidence rates among extrapulmonary tuberculosis cases. Diagnosis is often delayed because of the presence of several clinical manifestations and the high prevalence of secondary bacterial infections. Few reports have attributed secondary bacterial infections in patients with TOM to commensal Neisseria. Thus, understanding the pathogenic mechanisms and clinical features of commensal Neisseria is important, considering its recent presentation as an infection-causing pathogen. Neisseria mucosa is a commensal inhabitant in humans and is generally considered non-pathogenic but can cause infection in rare cases. Here, we report an atypical secondary infection caused by Neisseria mucosa in an 81-year-old woman with TOM being treated for pulmonary tuberculosis. Direct purulent otorrhea smear microscopy revealed no acid-fast bacilli using Ziehl-Neelsen staining, whereas the phagocytosis of gram-negative cocci by white blood cells was confirmed using Gram staining. Otorrhea culture revealed the growth of N. mucosa. Subsequently, M. tuberculosis infection in the otorrhea was identified using a culture-based method. Vigilance is critical for the early detection of TOM to prevent further complications. This report raises awareness regarding TOM and provides insight into the pathogenicity of N. mucosa in otitis media.

Numerical Analysis of Bacterial Meningitis Stochastic Delayed Epidemic Model through Computational Methods

Based on theWorld Health Organization(WHO),Meningitis is a severe infection of the meninges,the membranes covering the brain and spinal cord.It is a devastating disease and remains a significant public health challenge.This study investigates a bacterial meningitis model through deterministic and stochastic versions.Four-compartment population dynamics explain the concept,particularly the susceptible population,carrier,infected,and recovered.The model predicts the nonnegative equilibrium points and reproduction number,i.e.,the Meningitis-Free Equilibrium(MFE),and Meningitis-Existing Equilibrium(MEE).For the stochastic version of the existing deterministicmodel,the twomethodologies studied are transition probabilities and non-parametric perturbations.Also,positivity,boundedness,extinction,and disease persistence are studiedrigorouslywiththe helpofwell-known theorems.Standard and nonstandard techniques such as EulerMaruyama,stochastic Euler,stochastic Runge Kutta,and stochastic nonstandard finite difference in the sense of delay have been presented for computational analysis of the stochastic model.Unfortunately,standard methods fail to restore the biological properties of the model,so the stochastic nonstandard finite difference approximation is offered as an efficient,low-cost,and independent of time step size.In addition,the convergence,local,and global stability around the equilibria of the nonstandard computational method is studied by assuming the perturbation effect is zero.The simulations and comparison of the methods are presented to support the theoretical results and for the best visualization of results.
