Comparative evaluation of intensified short course regimen and standard regimen for adults TB meningitis: a protocol for an open label, multi-center, parallel arms, randomized controlled superiority trial (INSHORT trial).

BACKGROUND: Despite several incremental improvements in the management of tuberculous meningitis (TBM), the mortality rates remain high. In spite of national and international guidelines, variation in the choice, dose, and duration of drugs exist between countries and clinicians. We propose to evaluate a shorter and more effective regimen containing agents with augmented intracerebral drug exposure and anti-inflammatory approaches to improve disability-free survival among patients with TBM. Our strategy incorporates the various developments in the field of TBM over the last two decades and only few trials have evaluated a composite of these strategies in the overall outcomes of TBM. METHODS: An open label, parallel arms, randomized controlled superiority trial will be conducted among 372 participants across 6 sites in India. Eligible participants will be randomly allocated in 1:1:1 ratio into one of the three arms. The intervention arm consists of 2 months of high-dose rifampicin (25 mg/kg), moxifloxacin (400 mg), pyrazinamide, isoniazid, aspirin (150 mg), and steroids followed by rifampicin, isoniazid, and pyrazinamide for 4 months. The second intervention arm includes all the drugs as per the first arm except aspirin and the patients in the control arm will receive treatment according to the National TB Elimination Program guidelines. All participants will be followed up for 1 year after the treatment.  DISCUSSION: Current WHO regimens have agents with poor central nervous system drug exposure and is too long. It does not reflect the accumulating evidence in the field. We propose a comprehensive clinical trial incorporating the emerging evidence accrued over the last two decades to shorten the duration and improve the treatment outcomes. This multi-centric trial may generate crucial evidence with policy and practice implications in the treatment of TBM. TRIAL REGISTRATION: Clinical Trial Registry India CTRI/2023/05/053314.

Drug resistant TB spine in a two year old child: A case report.

Spinal tuberculosis (TB) is a disease of high morbidity that is associated with deformity and neurological sequelae, especially in growing children. Children diagnosed with spinal TB need to be monitored closely for clinical improvements. Previous history of antituberculous therapy (ATT), poor adherence to previous ATT, contact with persons having known drug-resistant (DR) TB, or clinical worsening despite regular ATT are strong indicators for the diagnosis of DR TB of the spine. We report a case of spinal DRTB in a two year old child with no previous history of ATT and contact with a person on irregular treatment for drug sensitive TB that did not show regression of the spinal lesions despite standard ATT.

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.

Active case-finding for tuberculosis in India.

Early identification of presumptive tuberculosis (TB) cases through active case-finding (ACF) would be an important complementary strategy to meet the national urgency in accelerating case detection to achieve the goals of 'End TB' strategy. ACF activities have yielded additional cases in different vulnerable groups in India. The yield of cases depends on the screening tool available, the characteristics of the high-risk population being screened, and most importantly, the linkage between effective diagnostic and treatment facilities. The ACF strategy could be both economically and epidemiologically relevant if it could bring down the level of transmission. This needs long-term research focusing on outcomes such as cases averted and reduction in the prevalence of the disease. Available evidence suggests that ACF is likely to be feasible in Indian settings but needs to be scaled up rapidly to create a good impact.
