Those with HIV and TB are more likely to have disseminated TB (where TB spreads to the bloodstream or to other organs outside the lungs). The most common sites of extrapulmonary TB in those with HIV are the lymph nodes, liver, spleen, and central nervous system (TB meningitis). [2] TB meningitis in those with HIV has a mortality rate of 40%. [2]
After accounting for those and other differences, the researchers calculated that the people who eschewed all multivitamins had the lowest risk of death during the first 12 years they were tracked.

If the outbreak of tuberculosis is in the brain, organs, kidneys, joints, or others areas, the patient may have active tuberculosis for an extended period of time before discovering that they are active.
