Neuromeningeal localization of tuberculosis (TB) is rare but remains the most severe with hight mortality and permanent neurological damage. Association of Poncet’s rheumatism and TB is rare, even less a neuromeningeal localization. We report here a case of optic nerve compression syndrome complicating tuberculous meningitis associated with Poncet’s rheumatism characterized by a good outcome. This was an 18-year-old female with no reported pathological history, who was admitted for obnubilation. The symptoms started two weeks before her hospitalization and were marked by fever and headache. On admission, the examination revealed obnubilation, bilateral pyramidal deficit syndrome, right ptosis and areactive mydriasis predominating on the right, meningeal syndrome, and intense inflammatory polyarthralgia. The brain CT showed meningeal contrast enhancement with moderate dilatation of ventricles. GeneXpert MTB/rif in CSF was positive. Rheumatoid factors (latex and Waaler-Rose test) and anti-CCP antibodies were negative. Anti-nuclear, anti-native DNA and anti-NAS antibodies were negative. Ophthalmological examination revealed optic nerve compression syndrome associated with extrinsic and intrinsic oculomotor paralysis in the right eye. Orbito-encephalic MRI showed compression of the optic nerve, and hydrocephalus. Under antituberculosis treatment, we noticed disappearance of arthralgia in three weeks, regression of intracranial hypertension and improvement of vision.展开更多

Neuro-meningeal involvement is rare but represents one of the most severe forms with high morbidity and mortality. We report the case of an ischemic stroke complicating neuromeningeal and pulmonary tuberculosis in a four-month-old infant at the National Hospital Center of children Albert Royer (Senegal). The case was a four-month-old, male infant with no history. His vaccination was up to date according to Senegal’s expanded vaccination program. There was no notion of tuberculosis contagion. He was seen for a prolonged fever for more than a month and chronic cough. He had moderate malnutrition. Neurological examination revealed coma, meningeal syndrome, generalized tonic convulsions and hypertonia. The pupils were in bilateral miosis. Osteotendinous reflexes were abolished with a bilateral Babinski sign. He also had severe respiratory distress, bilateral pulmonary condensation syndrome. Brain computed tomography was in favor of an ischemic stroke. The test GeneXpert MTB/RIF was positive on cerebrospinal fluid and gastric tubing fluid. The curative treatment was based on a quadruple therapy based on rifampicin, isoniazid, pirazinamide and ethambutol. The evolution was unfavorable with the death of the patient.展开更多

This difficulty is especially true for cerebrospinal fluid (CSF), and the low sensitivity and specificity for diagnosis hampers rapid detection and treatment in vulnerable populations. GeneXpert MTB/RIF Ultra has been shown to provide rapid results for detection of MTBC and associated Rifampin resistance, but there is limited data regarding standardized methods for CSF processing on this assay. In this study, we sought to provide guidance regarding the best methods for CSF processing, including optimal volumes to test, length of incubation with sample reagent and finally effects of long-term freezing on detection.展开更多

Neuro-meningeal tuberculosis (NMT) is responsible for death and severe permanent neurological damage. This poor prognosis requires early diagnosis and rapid initiation of specific treatment. Unfortunately, the great clinical polymorphism and the lack of specificity of radiological and biological signs are frequently responsible for a delay in diagnosis and management. Senegal is one of the African countries where tuberculosis has remained a concern until now. And there are no studies carried out on this subject. Objective: The objective of this study was to describe the profile and outcome of Neuro-meningeal tuberculosis (NMT) cases diagnosed at the infectious diseases department (SMIT) of Fann University Hospital in Dakar, (referral service for management of tuberculosis). Methods: We carried out a retrospective, descriptive and analytical study, reviewing medical records of adults diagnosed with NMT at the SMIT of Fann Hospital from January 2015 to December 2020. Results: We collected 55 cases of NMT. The median age was 38 years [range 16 - 77 years]. The sex ratio (M/F) was 3.23. HIV patients represented 41.82% of cases. A history of tuberculosis was found in 25.5% of cases. The delay in consultation was greater than one month in 60% of patients. Headaches were the most constant reason for consultation (94.55%). Meningeal signs were present in 94.55% of patients, and consciousness disorders and intracranial hypertension were present in 63.64% and 56.36% respectively. Nerve palsy was found in 38.18%. CSF was clear in 81.64%. GeneXpert MTB/RIF in CSF was performed in 33 patients and was positive in 4 patients. Brain CT was abnormal in 72.09% of cases. Tuberculoma, hydrocephalus and meningeal contrast enhancement were the main lesions. The neuro-meningeal localization was associated with a pulmonary form in 32.7%. The lethality rate was 21.8%;higher in women (46.2% vs 14.3%;p = 0.01), in patients with a delay in consultation > 1 month (p = 0.03), and in patients who presented with consciousness disorders (p = 0.007). Conclusion: Despite the availability of the GeneXpert MTB/RIF, diagnosis of NMT remains difficult. Because of its variable clinical expression and the low sensitivity of the GeneXpert MTB/rif in the CSF, it exposes patients to serious complications. Among the factors associated with death, we found consciousness disorders, a long delay in diagnosis.展开更多

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.展开更多

Tuberculosis can affect any part of ear ranging from tympanic membrane to labyrinth. The symptoms of tubercular otitis media like painless otorrhea, multiple perforations, pale granulations, facial paralysis and severe SNHL though well described in literature, are not always present hence diagnosis is often missed. Diagnosis is usually made by clinical and histopathology examination of specimen obtained intra operatively. Here, we discuss clinical presentation, diagnosis and management of a case with cholesteatoma and TB meningitis.展开更多

文摘Tubercular otitis media is an uncommon condition. Tuberculosis can affect any part of ear ranging from tympanic membrane to labyrinth. The symptoms of tubercular otitis media like painless otorrhea, multiple perforations, pale granulations, facial paralysis and severe SNHL though well described in literature, are not always present hence diagnosis is often missed. Diagnosis is usually made by clinical and histopathology examination of specimen obtained intra operatively. Here, we discuss clinical presentation, diagnosis and management of a case with cholesteatoma and TB meningitis.
