In addition, cases developing extrapulmonary TB had significantly higher ferritin levels at cohort enrollment than cases with pulmonary TB (1351 μg/L [725–1800 μg/L] vs. 491 μg/L [193–1250 μg/L]; p = 0.03), but similar hepcidin levels (9.4 nM [6.0–11.8 nM] vs. 11.5 nM [4.9–17.0 nM]; p = 0.47). Here, HAMP is linked to pulmonary tuberculosis.
