Hiponatremia severa por meningitis tuberculosa: complicación frecuente pero olvidada

Se presenta el caso de un paciente varón de 55 años que ingresó por alteración del estado de conciencia por una hiponatremia severa secundaria a una meningitis tuberculosa. No hubo mejoría de la hiponatremia al tratamiento con solución salina hipertónica, por lo cual se planteó el diagnóstico de síndrome de secreción inapropiada de hormona antidiurética (SIADH) y se evidenció mejoría con la restricción hídrica. El interés del presente caso es reportar una complicación frecuente pero olvidada de la meningitis tuberculosa.

We present the case of a 55-year-old male patient who was admitted due to an altered state of consciousness due to severe hyponatremia secondary to tuberculous meningitis. There was no improvement in hyponatremia after treatment with hypertonic saline solution, therefore the diagnosis of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) was proposed, and improvement was evidenced with fluid restriction. The interest of this case is to report a common but forgotten complication of tuberculous meningitis.

Case analysis of brain abscesses caused by Nocardia asiatica: A case report / 中国热带医学

@#Abstract: Objective　To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods　A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results　The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions　Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.

Potential Therapeutic Benefits of Brahma Rasayana in the Management of Tuberculous Cerebrovascular Disease - A Case Report

Tuberculous meningitis (TBM) is an air-borne infectious disease caused by the bacteria Mycobacterium tuberculosis that affects the central nervous system (CNS). Among all the incident cases of TB, CNS TB represents approximately 1% with TBM as the most grievous among all. The basic pathology in TBM is the inflammation of the arachnoid membrane, the pia mater and the cerebrospinal fluid (CSF). It typically presents as mild fever, headache, anorexia and general debility that progress over one to two weeks to cause severe headache, fever, vomiting, confusion, meningismus and cranial nerve deficits. The most common complications of TBM include hydrocephalus, optico-chiasmatic arachnoiditis, seizures and stroke. Out of these, tuberculous cerebrovascular disease is a common neurological sequelae. This case study elaborates the treatment line and observations made in a 29 year old male patient who presented with hemiparesis and significant sensory deficit following an event of tuberculous meningitis. MRI brain was suggestive of basilar meningitis, optico-chiasmatic arachnoiditis, infarcts and tuberculoma with chest X-ray revealing increased bronchovascular markings in bilateral lung fields. Initially on admission, Deepana-pachana was done followed by snehapana with Shadpala ghrta and Virechana as Sodhana karma. Abhyanga, Ushma Sweda, Churna pinda sweda and Jambeera pinda sweda were successively done allied with physiotherapy. Yogavasti with Vedanasthapana gana as Kashaya and Kalka was done intervened by Anuvasana vasti. Succeedingly, Murdhni taila prayoga and Marsha nasya were also incorporated with periodical neurological, hematological and biochemical assessment. On discharge, Brahmi kalyanaka ghrta and Brahma Rasayana were advised inclusive of physiotherapy.

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, 1 651 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.

Diagnosis and treatment of tuberculous meningitis / 中华神经科杂志

Tuberculous meningitis (TBM) is one of the most serious and lethal diseases in neurology. The early diagnosis and treatment of TBM still faces severe challenges. Acid-fast staining of cerebrospinal fluid and culture of Mycobacteriumtuberculosis are the "gold standard" for the diagnosis of TBM, but lack sensitivity. With the application of metagenomic next-generation sequencing technology, significant advances have been made in the early diagnosis of TBM. The optimal treatment regimen for TBM remains to be further explored and studied. This article intends to provide an overview of the pathogenesis, pathology, clinical manifestations, diagnosis and treatment advancement of TBM, and provide guidance for clinical practice.

Meningitis tuberculosa: un desafío diagnóstico en pediatría

Resumen La meningitis por Mycobacterium tuberculosis es infrecuente en pediatría y su diagnóstico definitivo representa un desafío clínico. Presentamos el caso de un lactante de dos años, que presentó un cuadro de meningitis crónica. Se logró el diagnóstico tras la sospecha imagenológica y la confirmación tras la búsqueda seriada del complejo M. tuberculosis por RPC en LCR y en biopsia de tejido cerebral. A pesar de sus complicaciones, el paciente respondió favorablemente al tratamiento antituberculoso. En Chile, la tuberculosis es infrecuente en niños y los síntomas son generalmente inespecíficos. Los hallazgos en RM cerebral asociados a alteraciones del LCR permiten sospechar el compromiso meníngeo precozmente. Se recomienda iniciar el tratamiento antituberculoso empírico ante la sospecha, ya que mejora el pronóstico. A pesar de los avances diagnósticos y terapéuticos, la meningitis tuberculosa sigue teniendo una alta tasa de complicaciones y un pronóstico ominoso.

Abstract Mycobacterium tuberculosis meningitis is rare in the pediatric population and its definitive diagnosis represents a clinical challenge. We present the case of a 2-year-old infant with chronic meningitis. Diagnosis was accomplished by suggestive radiological findings and serial search for M. tuberculosis complex by real-time polymerase chain reaction (qPCR) in cerebrospinal fluid (CSF) and in brain tissue. Despite the complications, the patient evolved favorably with the tuberculosis treatment. In Chile, tuberculosis is a rare disease in children and symptoms are generally nonspecific. Brain MRI findings associated with CSF alterations allow early suspicion of MTBC. Start of empirical antituberculosis treatment upon suspicion is recommended given it is associated with better prognosis. Despite diagnostic and therapeutic advances, MTBC continues to have a high complication rate and an ominous prognosis.

Tuberculosis y síndrome inflamatorio de reconstitución inmunológica. Caso pediátrico / Tuberculosis and immune reconstitution inflammatory syndrome. Pediatric case

La tuberculosis es una enfermedad muy frecuente en nuestro medio. A pesar de que la detección precoz y el tratamiento adecuado logran la curación en la mayoría de los pacientes, la dificultad en el diagnóstico, el abandono del tratamiento y la aparición de resistencia a los fármacos tradicionales generan que, en la actualidad, continúe siendo un importante problema de salud pública. En la Argentina, la tasa de morbilidad es de 25/100 000 habitantes, con un leve aumento en la mortalidad.Se presenta el caso de una paciente pediátrica con tuberculosis, que tuvo múltiples complicaciones asociadas a la enfermedad y a su tratamiento, entre las cuales se incluye el síndrome in-flamatorio de reconstitución inmunológica, también conocido como reacción paradojal al tratamiento antituberculoso. Este representa una consecuencia clínica adversa al restablecimien-to de la inmunidad en el paciente que padece una infección sistémica grave, como la tuberculosis miliar.

Tuberculosis is a very frequent disease in our environment. Although early detection and adequate treatment achieve cure in most patients, the difficulty in diagnosis, the abandonment of treatment and the appearance of resistance to traditional drugs generate that at present it continues to represent an im-portant public health problem. In Argentina, the morbidity rate is 25/100,000 inhabitants, with a slight increase in mortality.We present the case of a pediatric patient with tuberculosis and multiple complications associated with the disease and its treatment. One of these complications was the immune re-constitution inflammatory syndrome or paradoxical reaction to antituberculosis treatment. It represents an adverse clinical con-sequence of the restoration of immunity in the patient suffering from a serious systemic infection such as miliary tuberculosis.

Effect of Xingnaojing injection on rifampicin concentration in cerebrospinal fluid and prognosis of patients with severe tuberculous meningitis

@#Objective: To observe whether an Xingnaojing 醒脑静 injection could improve the prognosis of patients, by increasing rifampicin penetration through the blood-brain barrier. Methods: Patients with severe tuberculous meningitis were enrolled in this study. The concentrations of Xingnaojing in cerebrospinal fluid and blood in patients treated with Xingnaojing and control were determined by high performance liquid chromatography. The changes in cerebrospinal fluid and the improvement of clinical symptoms and signs, were evaluated two weeks after admission. The long-term prognosis of the patients in the two groups were evaluated by the Glasgow Outcome Scale (GOS). Results: The concentration of rifampicin in cerebrospinal fluid was significantly higher in the Xingnaojing group (1.77±0.17 μg/mL), than in the control group (1.27±0.16 μg/mL, p<0.05). The difference in concentration of rifampicin in the blood was not significant (P>0.05). The short-term effective rate of the Xingnaojing group was 92.5% (37/40), which was significantly higher than that of the control group (80%, 32/40, p<0.05). After 6 months, 75% (30/40) of the Xingnaojing group had good prognosis according to the GOS score, whereas that of the control group was 50% (20/40) showing significantly better long-term treatment effect of the Xingnaojing group compared to the control group (P<0.05). Conclusion: Xingnaojing injection improved rifampicin penetration into the central nervous system. The increase in rifampicin concentration in cerebrospinal fluid improved outcomes in patients with severe tuberculous meningitis.

Microbiological diagnosis of tuberculous meningitis: Phenotype to genotype

Tuberculous meningitis (TBM) is a commonly encountered central nervous system infection. Characteristic clinical, imaging and cerebrospinal fluid parameters help clinicians to make a prompt presumptive diagnosis that enables them to start empirical anti-tuberculosis treatment. There are several close mimic to TBM, such as partially treated pyogenic meningitis, fungal meningitis, sarcoidosis, meningeal metastases and meningeal lymphomatosis. Microbiological confirmation instils a sense of confidence amongst treating physicians. With conventional phenotypic methods (cerebrospinal fluid microscopy and culture), in more than 50 per cent patients, microbiological confirmation is not achieved. Moreover, these methods take a long time before providing conclusive results. Negative result does not rule out Mycobacterium tuberculosis infection of the brain. Genotypic methods, such as IS 6110 polymerase chain reaction and automated Xpert M. tuberculosis/rifampicin (MTB/RIF) assay system improved the TBM diagnostics, as results are rapidly available. Xpert MTB/RIF assay, in addition, detects rifampicin resistance. Xpert MTB/RIF Ultra is advanced technology which has higher (60-70%) sensitivity and is being considered a game-changer in the diagnostics of TBM. A large number of TBM cases remain unconfirmed. The situation of TBM diagnostics will remain grim, if low-cost technologies are not widely available. Till then, physicians continue to rely on their clinical acumen to start empirical anti-tuberculosis treatment.

Tuberculous meningitis in children: Clinical management & outcome

Although the occurrence of tuberculous meningitis (TBM) in children is relatively rare, but it is associated with higher rates of mortality and severe morbidity. The peak incidence of TBM occurs in younger children who are less than five years of age, and most children present with late-stage disease. Confirmation of diagnosis is often difficult, and other infectious causes such as bacterial, viral and fungal causes must be ruled out. Bacteriological confirmation of diagnosis is ideal but is often difficult because of its paucibacillary nature as well as decreased sensitivity and specificity of diagnostic tests. Early diagnosis and management of the disease, though difficult, is essential to avoid death or neurologic disability. Hence, a high degree of suspicion and a combined battery of tests including clinical, bacteriological and neuroimaging help in diagnosis of TBM. Children diagnosed with TBM should be managed with antituberculosis therapy (ATT) and steroids. There are studies reporting low concentrations of ATT, especially of rifampicin and ethambutol in cerebrospinal fluid (CSF), and very young children are at higher risk of low ATT drug concentrations. Further studies are needed to identify appropriate regimens with adequate dosing of ATT for the management of paediatric TBM to improve treatment outcomes. This review describes the clinical presentation, investigations, management and outcome of TBM in children and also discusses various studies conducted among children with TBM.

ETV in tuberculous meningitis with hydrocephalus and allergic reaction to VP shunt: a case report

Hydrocephalus is one of the most common complications of tuberculous meningitis (TBM) occurring in up to 85% of patients with the disease. The placement of a ventriculoperitoneal (VP) shunt is the most common form of treatment for hydrocephalus in tuberculous meningitis (TBM). Although allergic reactions to the silicone in shunt device are very rare, the authors describe a case of silicone allergy causing multiple VP shunt revisions. Alternative choice is endoscopic third ventriculostomy (ETV), but it is debatable. ETV has variable success in these patients and is generally not advisable in patients in the acute stages of the disease. A 19-year-old woman with hydrocephalus in tuberculous meningitis, who had undergone multiple VP shunt revisions, presented with shunt malfunction caused by allergic reaction of the tissue surrounding the shunt tubing. Laboratory examination demonstrated high level IgE, high level ESR, and PCR-TBC Positive, related to the allergic reaction. Patient with ETV success score of 50. Patients received ETV and release VSS Shunt. ETV has success in these patients. VP Shunts complications remain a difficult problem in neurosurgical clinical practice. The most typical complications are mechanical obstruction and infection. Allergy to the silicone shunt tubing is quite rare. Silicone allergy is an even more rare occurrence because of its high biocompatibility and low biological reactivity. It is a challenge for ETV when TBM has difficulty to recognize anatomical landmarks on this patient. It could also consider in patients who have shunt failure, and might be a better option than shunt revision.

Tuberculosis cerebral sin meningitis en un niño inmunocompetente / Cerebral tuberculosis without meningitis in a immunocompetent child

Resumen La tuberculosis (TBC) cerebral o tuberculoma(s) sin meningitis es una enfermedad poco frecuente y de alta morbimortalidad. Presentamos el caso clínico de un lactante de 11 meses, previamente sano, que consultó por fiebre prolongada y síntomas neurológicos. La RM de encéfalo mostró múltiples imágenes micronodulares e hidrocefalia. El estudio de LCR para bacterias, hongos y micobacterias fue negativo. Se prescribió terapia empírica como una meningoencefalitis subaguda y tratamiento antituberculoso tetraconjugado y corticoesteroides. La confirmación del diagnóstico de TBC cerebral se realizó por biopsia de la lesión, con presencia de inflamación granulomatosa crónica necrosante y bacilos ácido-alcohol resistentes. Se enfatiza la importancia de considerar esta presentación de TBC en niños, y la necesidad de la búsqueda exhaustiva del agente etiológico en diferentes líquidos y tejidos, aun por métodos invasores.

Cerebral tuberculosis TB (tuberculomas) without meningitis is an uncommon disease with a high morbidity and mortality. We report on a case that illustrates the complexity of this clinical presentation. An 11 month old, previously healthy male infant was brought to the clinic due to fever present during the last 1.5 months, associated with loss of neurodevelopmental goals and signs of endocranial hypertension. CT scan of the skull revealed dilatation of the ventricular system with transependimary edema; MRI showed multiple intra- and extra-axial micronodular images and hydrocephalus. Studies of CSF (cyto-chemical analysis, staining, culture for aerobes, fungi, mycobacteria, and molecular tests for TB were negative). Empirical management for subacute meningoencephalitis was prescribed complemented with tetraconjugated treatment for TB and steroids. As there was no microbiological isolation, biopsy of a cerebellar lesion was performed, which revealed chronic necrotizing granulomatous inflammation and acid-alcohol resistant bacilli. The diagnosis of cerebral TB without meningeal involvement was confirmed. The objective of the present report is to emphasize the importance of considering this presentation of TB in children, to remark the need of exhaustive search for the etiologic agent by obtaining samples of the different fluids and tissues even if it implies recurring to invasive methods.

Toxoplasma Encephalitis in a Patient with Human Immunodeficiency Virus Infection

Toxoplasma encephalitis is an opportunistic infection that may occur in immunocompromised or advanced HIV (Human Immunodeficiency Virus) patients and lead to serious complications in the CNS. We report a 44-year-old man with toxoplasma encephalitis combined with HIV infection. He was admitted with headache and neck stiffness. Brain computed tomography showed normal findings. Tuberculous meningitis was suspected from CSF and serum tests. However, his symptoms continued to progress, and toxoplasma encephalitis was diagnosed based on brain magnetic resonance imaging and serum tests.

Comparison of rapid detection effects of Mycobacterium tuberculosis in cerebrospinal fluid by RT-LAMP and RT-PCR / 国际检验医学杂志

Objective To investigate the effects of reverse transcription loop-mediated isothermal amplifica-tion(RT-LAMP)method and RT-PCR method for detecting Mycobacterium tuberculosis(MTB)in cerebro-spinal fluid(CSF)to provide a basis for its rapid diagnosis and clinical pharmacodynamic evaluation.Methods Eighty-five cases of CSF sample in the Bethune International Peace Hospital of PLA from December 2015 to April 2017 were selected for conducting the study and divided into the tuberculous meningitis(TBM)group(46 cases),suspected TBM group(25 cases)and control group(16 cases).The 16S rRNA region of MTB was used to design the specific primers.Then RT-LAMP and RT-PCR detection technological systems were estab-lished.Then the detection results by using the these two methods was analyzed.Results The positive detec-tion rates of the TBM group were 97.8% and 75.0% respectively,which of the suspected TBM group were 76.0% and 40.0% respectively,and which of the control group were 0.0% and 12.0% respectively,the posi-tive detection rate of each group in the RT-LAMP method was higher than that in the RT-PCR method,the difference was statistically significant(P<0.01);in the control group,adopting RT-PCR detection found non-specific amplification,while which was not found by adopting RT-LAMP method,indicating that the specifici-ty of RT-LAMP method was stronger than that of RT-PCR;the sensitivity of RT-PCR was 10.0 CFU/mL, which was higher than 1 CFU /mL of RT-LAMP.Conclusion RT-LAMP has the advantages of simpleness,sensitivity,rapidness and detecting viable bacteria,compared with PCR,which has strong specificity,easy op-erating,low cost and short time-consuming,is expected to be a routine detection tool of basic level and field medical institutions and developing countries.

A New Scoring System for the Differential Diagnosis between Tuberculous Meningitis and Viral Meningitis

BACKGROUND: Tuberculous meningitis (TBM) is associated with high mortality and morbidity despite administering anti-tuberculous chemotherapy to the patients. Differential diagnosis between TBM and viral meningitis (VM) is difficult in some clinical situations. METHODS: We reviewed and analyzed records of adult patients who were admitted and diagnosed with TBM or VM at a tertiary hospital in Korea, between January 2006 and December 2015. Diagnostic criteria for TBM were categorized into three groups: definite, probable, and possible TBM. The VM group included patients with no evidence of other meningitis who achieved complete recovery with only conservative treatments. Clinical, laboratory and radiological findings, as well as outcomes, were compared between the TBM and VM groups. RESULTS: Ninety-eight patients were enrolled. Among the study patients, 47 had TBM and 51 had VM. Based on univariate analysis and multivariate logistic regression, sodium 70 (U/L) in cerebrospinal fluid (CSF), protein > 160 (mg/dL) in CSF, voiding difficulty, and symptoms of cranial nerve palsy were significant predictive factors for TBM in the final model. We constructed a weighted scoring system with predictive factors from multiple regression analyses. Receiver operating characteristic curve analyses and decision tree analyses were plotted to reveal an optimum cutoff point as 4 with this scoring system (range: 0–13). CONCLUSION: For differential diagnosis between TBM and VM, we created a new weighted scoring system. This scoring system and decision tree analysis are simple and easy to apply in clinical practice to differentiate TBM from VM.

Utility of Cerebrospinal Fluid Adenosine Deaminase and C-Reactive Protein in patients with Meningitis

Introduction: We aimed to assess the utility of cerebrospinal fluid (CSF) Adenosine deaminase (ADA) and C-reactive protein (CRP) in differentiating various types of meningitis in adult population. Materials and methods: The present observational study, conducted in the Department of Medicine, Lokmanya Tilak Municipal Medical College and Hospital from February 2016 till August 2017, included all meningitis and meningococcemia cases diagnosed according to the clinical and/or laboratory criteria during the study period were included in the study. Comparisons were made with respect to various biochemical investigations between patient groups diagnosed with various types of meningitis. Results: 38% were diagnosed as bacterial meningitis, 54% as tubercular meningitis and rest as viral meningitis. CSF ADA was significantly higher in tubercular meningitis as compared to bacterial or viral meningitis. Similarly, CSF CRP was found to be significantly higher among patients with bacterial meningitis. In tubercular meningitis, CSF ADA and CRP were not found to be significantly associated with CSF cell count, CSF protein or ratio of CSF/Blood glucose. In bacterial meningitis, CSF CRP was found to be significantly higher among patients with CSF protein between 101 to 200 mg/dl. Using a cut off value of 5 IU/L, CSF ADA was found to have a sensitivity of 100% and specificity of 91.3% in diagnosing tubercular meningitis and with cut off value of 9 mg/L, CSF CRP had a sensitivity of 97% and specificity of 100% in diagnosing bacterial meningitis. Conclusion: CSF ADA and CRP should be included in the workup of meningitis patients.

Rupture of a Middle Meningeal Artery Pseudoaneurysm in Moyamoya Syndrome Related with Tuberculous Meningitis

We report a rare case of a patient with Moyamoya syndrome who presented with intracerebral hemorrhage resulting from rupture of a middle meningeal artery pseudoaneurysm. This 38-year-old woman was unconscious and hemiplegic when she was admitted to our hospital. The patient had mental retardation as a result of tuberculous meningitis infection at the age of one year. On radiologic examination, she had intracerebral hemorrhage in the right temporo-parietal lobe and an aneurysm in the middle meningeal artery with right internal carotid artery occlusion. The patient underwent surgical treatment for the hemorrhage and aneurysm. The radiologic data, intraoperative findings, and pathology were consistent with a diagnosis of pseudoaneurysm. In the current report, we describe a rare case of a patient with a history of tuberculous meningitis who developed Moyamoya syndrome and pseudoaneurysm, which resulted in a ruptured middle meningeal artery pseudoaneurysm and brain hemorrhage.
