Notes: 1) addition of E in the intensive phase of HRZ-containing regimens for PTB and EPTB is recommended in settings with prevalence of HIV or H resistance. 2) For patients at risk of neuropathy due to H (PLHIV, malnutrition, infants, adolescents, high-dose H), pyridoxine (B 6 )supplementation should be considered. 3) Adjuvant treatment is indicated for the treatment of TBM. 4) For the 6-month intensive treatment for TBM, higher dosages of R (22.5–30 mg·kg −1 ),H (15–20 mg·kg−1) and Z (35–45 mg·kg−1) are used compared with the doses for PTB and other forms of disease. 5) Corticosteroids should be given at the time of initial diagnosis of TBM and are also indicated in the treatment of TB pericarditis. Corticosteroids are sometimes used in the management of other complicated forms of TB (e.g. complications of airway obstruction by TB lymph nodes), but the evidence base for other indications is poor. Prednisone is given orally (2 mg·kg−1 once daily, maximum dosage of 60 mg·day−1) for 4 weeks. The dose should then be reduced gradually over 2–4 weeks before stopping. https://doi.org/10.1183/2312508X.10025322 223 CHILDREN AND ADOLESCENTS |E. LÓPEZ-VARELA ET AL.
