Management of four pregnant women with multidrug-resistant tuberculosis.

This case series describes the medical management of four pregnant women with active multidrug-resistant tuberculosis. None of the four patients were infected with human immunodeficiency virus. Three patients had disease due to multidrug-resistant Mycobacterium tuberculosis, and one had disease due to multidrug-resistant Mycobacterium bovis. Only one patient (patient 3) began retreatment during pregnancy, because her organism was susceptible to three antituberculosis drugs that were considered nontoxic to the fetus. Despite concern over teratogenicity of the second-line antituberculosis medications, careful timing of treatment initiation resulted in clinical cure for the mothers, despite some complications due to chronic tuberculosis and/or therapy. All infants were born healthy and remain free of tuberculosis. Pregnancy and multidrug-resistant tuberculosis need not be a public health disaster, as both conditions can be managed concurrently and successfully.
