Abstract
BACKGROUND: Worldwide, tuberculosis remains a major health concern, with an estimated 9.6 million people infected in the year 2014, of which one-third were women. Tuberculosis is estimated to be even more prevalent in pregnant women than the general population. To date there has been conflicting evidence on the maternal and neonatal complications of tuberculosis in pregnancy. OBJECTIVE: We sought to determine trends in the incidence of tuberculosis in pregnancy and to examine the associations between tuberculosis in pregnancy and maternal and fetal complications. STUDY DESIGN: We conducted a retrospective cohort study using the 2003 through 2011 Healthcare Cost and Utilization Project Nationwide Inpatient Sample. We identified hospital admissions during which women with and without tuberculosis delivered. The temporal patterns in incidence of tuberculosis were estimated, as were the rates of pulmonary and nonpulmonary tuberculosis. Multivariate logistic regression was used to examine the adjusted effects of tuberculosis on maternal and neonatal outcomes. RESULTS: During the study period, there were 7,772,999 births, of which 2064 were to women with tuberculosis, for an overall incidence of 26.6 per 100,000 births. From 2003 through 2011, there was an upward trend in the incidence of tuberculosis from 1.92-4.06 per 10,000 births (P < .0001), mostly due to increasing numbers of nonpulmonary tuberculosis. Compared with noncases, tuberculosis occurred with greater frequency in women who were 25-34 years of age and of Hispanic ethnicity. Significantly more women with tuberculosis had concurrent HIV. In addition, delivery hospitalizations with tuberculosis compared with those without tuberculosis were more likely to experience chorioamnionitis, preterm labor, postpartum anemia, blood transfusion, pneumonia, acute respiratory distress syndrome, and mechanical ventilation. Maternal mortality was significantly increased in women with tuberculosis. Congenital anomalies were higher among babies delivered to women with tuberculosis. CONCLUSION: The rate of tuberculosis in pregnancy is rising in the United States. Although this increase appears to be mostly due to nonpulmonary disease, there was also a high incidence of maternal respiratory complications, mortality, and postpartum obstetric morbidity.
