title: Intra-amniotic infection in patients with preterm prelabor rupture of membranes. Pathophysiology, detection, and management.
abstract: The recent increase in knowledge about infection and preterm delivery has engendered many new questions and should make us rethink our long held beliefs and management strategies. Although this article focused primarily on infection as an important factor in the pathogenesis of PPROM, multiple other causes do exist. The various serologic and amniotic fluid assays that can identify activation of the host immune and inflammatory responses as a consequence of the microbial invasion of the amniotic cavity detailed in the preceding paragraphs are very promising but not yet available for clinical use. These tests identify the fetus in the early stages of an infectious process, before the full clinical manifestations of chorioamnionitis. Should such fetuses be treated with antibiotics in an effort to sterilize the amniotic cavity? Should patients with documented microbial invasion be delivered immediately or is there room for a more conservative management with aggressive antibiotic in utero treatment, altering the natural course of PPROM, avoiding extremely preterm deliveries? Certainly many questions remain unanswered. Continuing the search for information on the relationship between infection and PPROM can only add hope to one day finding an option for prevention, because many and probably most cases of PPROM are apparently caused by infection, and the opportunity for preventing this problem most probably lies here.
