Brief Summary
The aims of this project are to:
- 1.To evaluate the pharmacokinetics of first line antituberculosis drugs (isoniazid, rifampicin, pyrazinamide and ethambutol) when applying the 2010 WHO/IUATLD dosing guidelines across pediatric populations (0-12 years of age, HIV infected and uninfected, and with varied nutritional status) in Cape Town, South Africa and Blantyre, Malawi.
- 2.To evaluate an 8-hourly weight band-based dosing strategy for lopinavir/ritonavir using the commercially available lopinavir/ritonavir (4:1 ratio) in children in South Africa receiving rifampicin-based antituberculosis treatment.
- 3.To evaluate the pharmacokinetics of nevirapine in children in Malawi receiving rifampicin-based antituberculosis treatment.

Eligibility Criteria
You may qualify if:
- ALL STUDY PARTICIPANTS
- Aged \< 12 years.
- Weighing \> 1.5 kg and \< 30 kg.
- Written informed permission of parent or legal guardian for their child to participate.
- Absence of clear indication of unwillingness or refusal to participate, and in children \> 7 years of age, assent to participate.
- No contraindications to PK sampling (children with obviously very poor venous access will not be included).
- Able to comply with study visits and procedures including regular adherence to routine medication, and adherence to the study medication.
- Enrollment will be deferred in children with acute severe illness which would likely jeopardize participation (such as illness causing severe respiratory impairment, acute severe diarrhea, acute central nervous system impairment, severe life threatening systemic illness, or other severe conditions requiring hospitalization which would jeopardize participation). Children may be enrolled after recovery from acute illness.
- ADDITIONAL CRITERIA FOR THE MAIN TB COHORT AND SUBSTUDIES
- Main TB cohort
- LPV SUBSTUDY
- CASES \& CONTROLS
- Children in whom ART with a LPV/r-containing regimen is indicated, OR, Children established on a LPV/r-containing regimen.
- ALT \< 5-times the upper limit of the normal range.
- Children weighing 3.0 - 19.9 kg.
- +9 more criteria
You may not qualify if:
- Indication for increased or reduced doses of 1st-line antiTB drugs (e.g. marked hepatic or renal impairment, TB meningitis).
