Achievement of Target Glycemic Goal with Simple Basal Insulin Regimen in Women with Gestational Diabetes: A Prospective Cohort Study.

There is little evidence concerning the need to treat gestational diabetes (GDM) in the same way as pregestational diabetes. We evaluated the efficacy of the simple insulin injection (SII) regimen for achieving the target glucose goal without increasing adverse perinatal outcomes in singleton pregnant women with GDM. All subjects underwent self-monitoring of blood glucose (SMBG), and insulin therapy was indicated according to the SMBG profile. Insulin was initially started with the SII regimen, in which one daily injection of NPH insulin before breakfast was used, and another NPH injection was added at bedtime, if necessary. We used the target glucose as <95 mg/dL at fasting and <120 mg/dL postprandial and accepted <130 mg/dL for the latter. If the target glucose did not reach with the regimen, we switched to the multiple daily injection (MDI) with additional prandial insulin aspart. We compared the SMBG profile before delivery as well as the perinatal outcomes between the SII and MDI groups. Among 361 women (age 33.7 years, nullipara 41%, prepregnancy body mass index 23.2 kg/m2) with GDM, 59%, 18%, and 23% were in the diet-alone, SII, and MDI groups, respectively. Consequently, regarding women requiring insulin therapy, 43% were treated with the SII regimen throughout pregnancy. The severity of baseline hyperglycemia according to the SMBG data at baseline was the MDI>the SII>the diet group. The rate of achieving target glucose levels before delivery in the SII group at fasting, postprandial < 120 mg/dL and <130 mg/dL were 93%, 54% and 87%, respectively, which were similar to that in the MDI group (93%, 57%, and 93%, respectively), with no significant differences in perinatal outcomes. In conclusion, more than 40% of women with GDM requiring insulin therapy achieved the target glucose goal with this simple insulin regimen without any increase in adverse effects.

Vaginal Ureaplasma urealyticum or Mycoplasma hominis and preterm delivery in women with threatened preterm labor.

BACKGROUND: Amniotic fluid infection with Ureaplasma urealyticum or Mycoplasma hominis can cause chorioamnionitis and preterm birth. The aim of this study was to examine whether vaginal Ureaplasma urealyticum/Mycoplasma hominis colonization is predictive of preterm delivery in patients exhibiting signs of threatened preterm birth or those with asymptomatic short cervix. METHODS: The present retrospective study, which was performed in a perinatal tertiary center, included patients carrying a singleton pregnancy who were referred to the emergency Ob/Gyn unit because of regular preterm uterine contractions and/or short cervical length (<20 mm) at 22-33 weeks of gestation, and in whom a vaginal U. urealyticum/M. hominis examination (Urea-arginine LYO-2, BioMerieux®) was performed. Univariate and multivariate analyses were performed to assess the association between vaginal U. urealyticum or M. hominis and chorioamnionitis or preterm delivery. RESULTS: The median gestational age of the 94 enrolled patients was 29.9 weeks, and 54 (57%) of the patients were vaginal U. urealyticum/M. hominis-positive. The preterm delivery rate in the positive group was higher than in the negative group (53 versus 25%; p = .007). Vaginal U. urealyticum/M. hominis positivity was found to be an independent risk factor for preterm birth at <37 weeks of gestation (adjusted odds ratio = 4.0, 95% confidence interval, 1.1-15.3) in a multivariate analysis adjusted for age, history of preterm delivery and conization, gestational age, cervical length, presence of vaginal bleeding, vaginal fetal fibronectin and serum C-reactive protein at test. U. urealyticum/M. hominis positivity was not associated with delivery at <34 weeks or chorioamnionitis. CONCLUSION: A positive vaginal U. urealyticum/M. hominis culture is an independent predictive factor for preterm birth in patients with symptomatic threatened preterm labor and/or short cervix.
