    PurposeThe influence of pregnancy on tuberculosis (TB) has not been well studied. This study aimed to investigate the demographics, clinical characteristics and outcomes of pregnant-related TB compared with the general population with TB.MethodsWe retrospectively analysed medical records of women during pregnancy or within six months postpartum with active TB who were admitted to the West China Hospital between 2011 and 2022. According to age, gender and admission time, the general population with active TB was matched at a ratio of 1:2, and the demographics, clinical characteristics and outcomes were compared.ResultsAll the participants in both the pregnant and non-pregnant groups were females, averaging 26 years old, with a majority of Han nationality (72.4% vs. 69.5%, respectively). The two groups were comparable (p < .05). Pregnant TB cases showed higher rates of fever (61% vs. 35%), dyspnoea (39.9% vs. 18.7%), neurological symptoms (34.4% vs. 11.0%) and miliary TB (24.5% vs. 10.9%) compared to non-pregnant cases (p < .05). Additionally, the pregnant group exhibited lower red blood cell counts (3.62 × 109/L vs. 4.37 × 109/L), lower albumin levels (31.20 g/L vs. 40.40 g/L) and elevated inflammatory markers (p < .05). Pregnant women with TB had severe outcomes, with 16.3% requiring intensive care unit (ICU) care and a 3.3% TB-related mortality rate - higher than local averages. In contrast, the non-pregnant group had lower rates (0.8% for ICU admission, and no TB-related deaths). Moreover, active TB during pregnancies led to a high rate of spontaneous abortion (34.1%), with military pulmonary TB identified as the sole risk factor for severe TB in pregnancies (OR: 3.6; 95% CI: 1.15, 11.34).ConclusionsManifestations of TB in pregnant women differ from those in the general population with TB. Pregnancy complicated with active TB greatly harms the mother and foetus and requires special attention in the future.
