Insights
Treatment for central nervous system tuberculosis tuberculomas may require longer than the standard 1 year. Extended anti-tuberculous therapy duration, based on imaging, can lead to lesion resolution in pediatric cases.
Area of Science:
- Neurology
- Infectious Diseases
- Pediatrics
Background:
- Central nervous system tuberculosis (CNS TB) requires anti-tuberculous therapy (ATT).
- Standard treatment duration for tuberculomas is typically 1 year.
- Guidelines for extended ATT in persistent CNS TB tuberculomas are lacking.
Observation:
- A series of six pediatric CNS TB cases with persistent tuberculomas were analyzed.
- Patients received ATT for 23–32 months, guided by neuroradiological scan resolution.
- Treatment response was monitored via changes in granuloma size and number.
Findings:
- All patients showed a decrease in tuberculoma size and number.
- One patient achieved complete resolution of lesions.
- After ATT cessation, granuloma size stabilized in most cases, with one showing an increase.
Implications:
- Extended ATT duration may be necessary for complete resolution of CNS TB tuberculomas.
- Treatment duration should be individualized based on patient response and imaging.
- Further research is needed to establish definitive guidelines for prolonged ATT in CNS TB.
Abstract:
The usual treatment duration of tuberculomas recommended is 1 year. While anti-tuberculous therapy is of absolute necessity for the treatment of central nervous system tuberculosis, no clear guidelines exist regarding the duration of therapy in case of persistent tuberculomas. We present a series of six cases of children with central nervous system tuberculosis who received anti-tuberculous therapy for a period varying between 23 and 32 months depending on the resolution of lesion seen in neuroradiological scans of the patients. Decrease in number and size of granuloma were noted in all patients while one patient showed complete resolution. After stopping anti-tuberculous therapy, the size of the granuloma remained the same, while in one patient an increase was noted. Thus, the duration of anti-tuberculous therapy in patients with tuberculoma may vary and may be required for longer time based on treatment response.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
