Tuberculosis: current implications and management in obstetrics.

Abstract

After years of decline, tuberculosis has again emerged as a serious public health issue. Following the introduction of effective chemotherapy at mid-century, cases of tuberculosis decreased until 1986. Since that time, the number of cases of tuberculosis have dramatically increased, particularly among young persons. The reemergence of tuberculosis is localized to urban areas and is linked to the increase in the incidence of human immunodeficiency virus infection and drug resistance. Since pregnant women are at risk for tubercular infection, an effective method exists to identify women who are asymptomatically infected, provide them with treatment to prevent progression of disease, and investigate their contacts. This review will discuss the issues of diagnosis and treatment of asymptomatic infection and active tuberculosis in pregnant women. Additionally, the need for universal screening of all prenatal patients and the benefit and potential perinatal toxicity of chemotherapy in both immunocompetent patients and those infected with human immunodeficiency virus will be addressed.
