Some patients with tuberculosis experience a confusing problem: even though they are taking their TB medications correctly, their symptoms and test results get worse instead of better. This is called a paradoxical reaction, and it happens in about 1 in 5 people without HIV who are treated for TB. This study is trying to understand why this happens by collecting blood samples, imaging scans, and clinical information from people who experience this reaction and comparing them to people whose TB improves as expected.
Doctors struggle to diagnose paradoxical reactions quickly because the worsening can look like treatment failure or a new infection. By understanding what causes this reaction—through blood tests and scans—researchers hope to develop ways to identify and predict it earlier, so doctors can reassure patients and adjust their care if needed.

You would have regular visits at the research clinic where you'll meet with doctors who will examine you, ask about your TB symptoms, and collect blood and sputum samples. You'll also have imaging scans (PET/CT) to look at your lungs and lymph nodes. The study may last several months, depending on your TB treatment course. An optional procedure called leukapheresis (collecting certain white blood cells) may be offered, where blood is drawn, some cells are removed for research, and the rest is returned to you.
