Perinatal tuberculosis New challenges in the diagnosis and treatment of tuberculosis in infants and the newborn

With increasing rates of tuberculosis (TB) infection and disease worldwide, the rate of perinatal TB is also affected. A high index of suspicion by health professionals, in both the developed and developing world, is required to detect and manage tuberculosis in pregnancy and the early newborn period. Differences in immune responses in the fetus and neonate add to the diagnostic difficulties already recognised in young children. Although specific guidelines for the treatment of this potentially devastating disease are lacking due to paucity of experience, outcome is favourable, if the condition is recognised and treated according to existing TB protocols. HIV co-infection, multi- and extensively-drug resistant (MDR/XDR) TB contribute to the challenges. New diagnostic and vaccine developments hold future promise, but much work is needed to completely understand the complex immune responses to tuberculosis and control this disease.
