Background. The study investigates the influence of the length of membrane rupture period among pregnant women with preterm premature rupture of membranes (PPROM) between the 32nd and 34th weeks of gestation on the development of chorioamnionitis and the congenital infection of a newborn. It seeks to ascertain the values of indicators in mother’s blood that enable to predict chorioamnionitis and funisitis for mothers, and congenital infection for newborns. Materials and methods. A retrospective study of case records of women with PPROM at 32 (32 w. + 0 d)–34 (33 w. + 6 d) weeks of gestation and their newborns was performed. Two comparative groups were made: 1) of women who had funisitis and / or chorioamnionitis with or without deciduitis and 2) of women having no proved inflammation (according to the results of histological examination of placentae). Analogically, comparative groups were made of their newborns: those who had diagnosis of congenital infection and those who had no infection. The duration of membrane rupture period and the blood markers were investigated in all the groups. Results. The study included 135 women. Duration of the membrane rupture period lasted 85.17 ± 84.72 hrs in the group of women who had histological inflammation, and 40.06 ± 56.57 hrs in the group with no inflammation, P = 0.01, AUC = 0.735; the critical membrane rupture period value for developing intrauterine infection by the Youden index was 43.7 hrs. The corresponding maternal CRP values (mg/l) were 25.85 ± 40.27 vs. 5.23 ± 7.88 (P = 0.01, AUC = 0.6), the Youden index 4.6 mg/l. For the mothers of the newborns diagnosed with infection, the duration of the membrane rupture period was 55.95 ± 65.04 hrs, for the mothers of the newborns without congenital infection it was 40.25 ± 73.71 hours. Respectively, CRP values for the mothers of newborns averaged 12.25  ±  22.14  mg/l vs. 4.8 ± 4.82 mg/l (P = 0.005). Conclusions. Longer membrane rupture period and higher maternal CRP are correlated with inflammatory changes in the placenta and umbilical cord, thus they can be used as the prognostic indicators of intrauterine infection. When the duration of the membrane rupture period lasts ≥44 hrs, the risk of chorioamnionitis and funisitis increases five times; when the maternal serum CRP is higher than 5 mg/l, funisitis / chorioamnionitis is twice more frequent than at lower than 5 mg/l CRP values.

Abstract Objective: A current descriptive assessment of perinatal outcomes in pregnancies complicated by previable preterm premature rupture of membranes (pPPROM) at <24 weeks of gestation, after expectant treatment. Study design: Maternal and short-term neonatal data were collected for patients with pPPROM. Results: Seventy-three patients with 93 fetuses were hospitalized with pPPROM at 15–24 weeks’ gestation. Among these patients, 27.4% (n=20) chose pregnancy termination, 27.4% (n=20) miscarried and 45.2% (n=33) proceeded to live births. After a median latency period of 38 days, ranging from 1 to 126 days, 24 singletons and 20 multiples were live-born, of whom 79.5% (n=35) survived the perinatal period. The main neonatal sequelae were pulmonary hypoplasia (29.5%; n=13), connatal infection (56.8%; n=25), intraventricular hemorrhage (25%; n=11; resulting in five neonatal deaths) and Potter’s syndrome (15.9%; n=7). Nine newborns died, within an average of 2.8 days (range, 1–10 days). The overall neonatal survival rate was 51.5% – including miscarriages but not elective terminations. The intact survival rate was 45.5% of all live-born neonates. Conclusions: Even with limited treatment options, overall neonatal survival is increasing. However, neonatal mortality and morbidity rates remain high. The gestational age at membrane rupture does not predict neonatal outcome.

Abstract Objective We aimed to investigate the prognostic value of maternal serum haptoglobin levels in patients presenting with preterm premature rupture of fetal membranes (PPROM) during the second and the third trimesters of pregnancy. Methods In this case control study, 60 patients were recruited (30 pregnant women with PPROM between 26–34 weeks of gestation and 30 healthy, gestational-age-matched pregnant women without PPROM). White blood cell count (WBC), interleukin 6 (IL-6), C-reactive protein (CRP), sedimentation rate, and haptoglobin levels were measured. Results The mean age, gestational week, gravida, and parity of the 2 groups were statistically comparable (P>0.001). There was a statistically significant difference between the 2 groups in terms of haptoglobin values (p<0.001). The mean haptoglobin level was 115.5+33.1(mg/dl) in the PPROM group and 66.5+42.6 (mg/dl) in the control group. ROC curve analysis was performed to determine whether the level of haptoglobin alone could diagnose PPROM as an independent marker. It was shown that the level of 94.5 mg/dL for haptoglobin could indicate the diagnosis of PPROM with 80% sensitivity and specificity Conclusion Maternal serum haptoglobin levels may be a diagnostic marker for suspected PPROM cases when membrane rupture diagnosis is not accurate based on physical examination and other diagnostic tests.

Background: Pre-labor rupture of membranes is defined as amniotic membrane rupture before the onset of labor contractions, and if it happens before 37 weeks, it is called preterm premature rupture of membranes (PPROM). Several organisms commonly present in the vaginal tract are E.coli, Group-B streptococci, staphylococcus aureus, chlamydia trachomatis, Gardnerella vaginalis and Enterococcus faecalis which secrete proteases that degrade collagen thereby weakening  the fetal membranes leading to PPROM. Appropriate antibiotic therapy has a significant role in the prevention and treatment of maternal and neonatal complications.Methods: This was a prospective observational study done in the department of obstetrics and gynaecology, Narayana medical college, Nellore. Selectively 100 patients with complaint of PPROM admitted to labor room were included in the study. Diagnosis of membrane rupture was established by speculum examination, and high vaginal swabs are taken and sent to laboratory for identifying bacteria using gram staining and cultured in aerobic and anaerobic methods. Antimicrobial susceptibility testing of the organisms was performed by disk diffusion method by Kirby and Bauer.Results: Out of 100, high vaginal swabs had growth in 82 patients, and 18 were sterile. The repeatedly isolated organism in patients with PPROM is E.coli amounting 32%, followed by candidal species 20%. Staphylococci are scoring 11% and enterococci 8%. However, organisms like gardenella vaginalis and Group B streptococcus are least common with a score of 6% and 5% respectively. In this study, E.coli is highly sensitive to tigecycline, colistin 100% each and highly resistant to gentamycin and amikacin.Conclusions: In this study, E.coli is related to the maximum number of cases with preterm premature rupture of membranes. Appropriate use of antibiotics significantly lowers maternal morbidity and neonatal mortality.
