When should we start anti TB in HIV?
Anti-retroviral therapy should ideally be initiated within the first 2 weeks of TB treatment for patients with CD4 cell counts <50/mm3 and by 8-12 weeks of TB treatment initiation for patients with CD4 cell counts ≥50/mm3.
What is prophylactic treatment for TB?
The standard regimen for treatment of latent TB infection is nine months isoniazid, also known as isoniazid prophylaxis therapy (IPT). Pyrodoxine should be given with isoniazid (Udani et al. 1971).
WHO TB prophylaxis guidelines?
The following options are recommended for the treatment of LTBI regardless of HIV status: 6 or 9 months of daily isoniazid, or a 3-month regimen of weekly rifapentine plus isoniazid, or a 3 month regimen of daily isoniazid plus rifampicin.

Other vaccines might be recommended outside the routine age window in children with HIV, including pneumococcal conjugate vaccine (PCV13), or human papillomavirus vaccine in males. Live attenuated influenza vaccine (LAIV) is contraindicated for children with HIV.
Does TB affect CD4 count?
In multivariate analysis a decrease in TB mortality was most strongly associated with CD4 count (Adjusted HR 0.82 per increase of 50 cells/mm3, 95% CI: 0.81–0.83, p < 001) and the initiation of ART during TB treatment (Adjusted HR 0.39, 95% CI: 0.35–0.42, p < 0.001).

One-third of the world’s population has LTBI. The TB germs are dormant (asleep) in the body.
What is the relationship between the number of CD4 cells and the risk of developing tuberculosis?
In clinical perspectives, it means that HIV positive patients with CD4+ T cell count < 200 cells/mm3 have 2.88 times more likely to develop incident TB compared with patients who have CD4+ T cell count > 200 cells/mm3 (Fig.
