The role of vitamin C in prevention of preterm premature rupture of membranes.

Preterm premature rupture of membranes (PPROM) is one of the most important complications of the pregnancy and cause perinatal morbidity and mortality. History of PPROM is a risk factor of recurrent PPROM. Vitamin C plays an important role in collagen metabolism and increases resistance maintenance of the chorioamniotic membranes. The aim of this study is to evaluate the role of vitamin C supplementation in prevention of PPROM in women with a positive history of PPROM. This clinical trial study was performed on 170 pregnant women with the history of PPROM, with singleton pregnancy and gestational age 14 weeks in Imam-Reza Hospital, Mashhad University of Medical Sciences during 2008 to 2010. They were randomly divided into two groups. The case patients received 100 mg vitamin C daily from 14th weeks of gestation. PPROM occurrence was compared between two groups as an indicator of the protective effect of vitamin C supplements. PPROM occurred in 44.7% of controls and 31.8% of cases (P < 0.05). PROM occurred in 34.1% of controls and 18.8% of cases (P < 0.05). Pregnancy was terminated at term gestation in 21.2% of controls and 49.4% of cases (P < 0.05). Rupture of membranes was significantly decreased in the case group. Vitamin C supplementations after 14th weeks of gestation can prevent from PPROM in women with the history of PPROM.
