Changing Clinicoradiologic Spectrum of Intracranial Neurotuberculosis in Children: A Cross-sectional Study

Clinical efficacy of dexamethasone combined with isoniazid in the treatment of tuberculous meningitis and its effect on peripheral blood T cell subsets

Objective

To investigate the clinical efficacy of dexamethasone (Dex) combined with isoniazid in tuberculous meningitis (TBM) and its effect on peripheral blood T cell subsets.

Methods

A total of 235 patients with TBM were divided into the control group (117 cases) and the observation group (118 cases). Both groups were given conventional treatment, the control group was further given isoniazid, and the observation group was further given Dex combined with isoniazid. The therapeutic effect and improvement of clinical symptoms were evaluated, peripheral blood T lymphocyte subsets and neurological function were observed, and patients' prognosis was evaluated.

Results

The total effective rate of the observation group was higher. The recovery time of cerebrospinal fluid (CSF) pressure, CSF protein content, CSF cell count, and hospital stays in the observation group were shorter. The duration of cervicogenic headache, fever, vomiting, and coma in the observation group was shorter. CD3+ and CD4+/CD8+ proportions in the observation group were higher, and CD8+ proportion was lower. The NIHSS score and MRS score of the observation group were lower, as well as the incidence of adverse reactions.

Conclusion

Dex combined with isoniazid alleviates clinical symptoms and neurological abnormalities and regulates peripheral blood T cell subsets in TBM.

Acute demyelinating encephalomyelitis in a child with pulmonary tuberculosis

Tuberculosis is a leading cause of mortality in children worldwide. One of the greatest challenges in its management is the difficulty of diagnosis as the manifestations are non-specific and often mimic other illnesses. Neurological infection occurs in approximately 1% of patients diagnosed with tuberculosis, and usually takes the form of tuberculous meningitis or tuberculoma. An 11-year-old girl who was diagnosed with acute disseminated encephalomyelitis, a rare immunological manifestation of tuberculosis, is presented. She recovered completely after a course of high-dose systemic corticosteroids in addition to anti-tuberculosis treatment. Considering the immense burden of this infectious disease, recognition and understanding of the uncommon manifestations are important to enable appropriate and timely treatment.Abbreviations: ADEM: acute disseminated encephalomyelitis; ATT: anti-tuberculosis therapy; CBNAAT: cartridge-based nucleic acid amplification test; CNS: central nervous system; CSF: cerebrospinal fluid; CT: computed tomography; FLAIR: fluid attenuated inversion recovery; IFN: interferon; MRI: magnetic resonance imaging; MTB: Mycobacterium tuberculosis; TB: tuberculosis; TNF: tumour necrosis factor.

Longitudinal extensive transverse myelitis due to tuberculosis: A case report

Neurotuberculosis is a potentially fatal disease that can present with upper or lower motor neuron symptoms. Longitudinally extensive transverse myelitis (LETM) is characterized by contiguous inflammatory lesions of the spinal cord extending to three or more vertebral segments. The causes of LETM include infections, neoplasm, and autoimmune diseases. Mycobacterium tuberculosis is a rare cause of transverse myelitis. Here, we report a 21-year-old Afghan female who was referred with chronic progressive quadriparesis and showed LETM on cervical MRI. This report indicates that tuberculosis should be considered as a differential diagnosis of LETM, especially in endemic areas.
