Eradication of cervical canal colonization associated with prophylactic cervical cerclage: the look further study.

OBJECTIVES: The perioperative management of the cervical cerclage procedure is not unified. In general population controlling microbiome cervical status does not affect obstetric outcomes, but it might be beneficial in patients with cervical insufficiency. The aim of our study was to present the obstetric, neonatal and pediatric outcomes of patients undergoing the cervical cerclage placement procedure in our obstetric department using a regimen of care that includes control of the microbiological status of the cervix and elimination of the pathogens detected. MATERIAL AND METHODS: Thirty-five patients undergoing cervical cerclage in the 2nd Department of Obstetrics and Gynecology, Medical University of Warsaw, were included in the study. The procedure was performed only after receiving a negative culture from the cervical canal. RESULTS: Thirty-one (88.6%) patients delivered after the 34th and twenty-eight (80.0%) after the 37th week of gestation. The colonization of the genital tract was present in 31% of patients prior to the procedure, in 42% of patients - during the subsequent pregnancy course and in 48% of patients - before delivery. A total of 85% of patients who had miscarriage or delivered prematurely had abnormal cervical cultures. In patients with normal cervical cultures, and 91.7% of women delivered at term. No abnormalities in children's development were found. CONCLUSIONS: Controlling microbiological status of the cervical canal results in better or similar outcomes to those reported by other authors in terms of obstetric and neonatal outcomes. Active eradication of the reproductive tract colonization potentially increases the effectiveness of the cervical cerclage placement.

Gestational weight gain and glycemic control in GDM patients with positive genital culture.

OBJECTIVE: Gestational diabetes mellitus (GDM) is related to many complications of pregnancy. The aim of the study was the assessment of cervical colonization in GDM patients and its correlation with inappropriate glycaemic control and gestational weight gain (GWG). MATERIALS AND METHODS: The study included 483 women with GDM in a singleton pregnancy who delivered at term. Cervical smears samples were collected >35th week of gestation and cultured for aerobic and aerobic bacteria, and fungi. The patients were divided into two groups on the basis of cervical culture test results: women with negative and positive cervical culture results. Gestational weight gain was estimated in both groups as inadequate, adequate or excessive based on pre-gestational body mass index (BMI) according to the Institute of Medicine (IOM) guidelines. GWG and need of insulin therapy were used as an indicator of complying with dietary recommendations. RESULTS: Patients with positive cervical culture results more frequently had pre-pregnancy BMI >35kg/m2 (4.9% vs 9.5%, p = 0.0508) than patients who had negative cervical culture results. One third (32.1%) of patients had one, and 9.3% had at least two microorganisms in their genital tracts. The most frequent bacteria species isolated was Streptococcus agalactiae (20.1%). Fungi were present in 14.1% of the cervical cultures. Patients with GDM with inadequate GWG more often had genital tract's colonization with Enterococcus spp. (6.83% vs. 1.19% vs. 1.83%, in group with inadequate GWG vs. adequate GWG vs. excessive GWG respectively p = 0.007). CONCLUSION: Insulin therapy in GDM patients was not correlated with the presence of microorganisms in genital tracts. Inadequate GWG in GDM may be linked to genital tract colonization with Enteroccocus spp. Genital colonization during pregnancy among patients with GDM is more often among patients' with pre-pregnancy BMI >35 kg/m2.

Gestational diabetes mellitus (GDM) - do the number of fulfilled diagnostic criteria predict the perinatal outcome?

OBJECTIVES: The aim of the study was to check whether the number of fulfilled diagnostic criteria of gestational diabetes mellitus (GDM) had any association with patients' characteristics and pregnancy outcomes. MATERIAL AND METHODS: A total of 756 women with single pregnancies and GDM who gave birth at the 2nd Department of Obstetrics and Gynecology of the Medical University of Warsaw between 01.2013-12.2016 were included in a retrospective analysis. Patients were divided into 2 groups: A - 499 patients diagnosed with GDM on the basis of one diagnostic criterion, B - 257 patients diagnosed with GDM on the basis of more than one diagnostic criterion. RESULTS: Patients from group A had lower pre-pregnancy BMI than those from group B (median 24.9 kg/m2 vs. 26.5 kg/m2, p=0.0003). Women from group A were less frequently treated with insulin than women from group B (19.1% vs. 32.7%; p=0.00002). Group A had lower median OGTT levels than group B (85.9 mg/dL vs. 94.1 mg/dL, p=0,0001; 160.2 mg/dL vs. 197.6 mg/dL, p=0.0001; 144.8 mg/dL vs. 167.0 mg/dL,p=0.0001; respectively). Moreover, in group B the average week of labor was earlier than in group A (mean 38,1 and 38,5 weeks of gestation, p=0,0006). CONCLUSIONS: Patients who fulfilled more than one diagnostic criterion for GDM may have worse pregnancy outcome. We think that a number of fulfilled diagnostic criteria for GDM may be an important risk factor for insulin therapy during pregnancy and earlier gestational age at delivery.

New criteria for gestational diabetes mellitus - do they impact the outcome?

OBJECTIVE: The aim of the study was to compare the perinatal outcome of pregnancies in mothers who were diagnosed with gestational diabetes mellitus (GDM) with previous versus current Polish Gynecological Society (PTG) criteria. METHODS: 475 patients were divided into three groups. In group A, the patients only met the previous PTG criteria for a GDM diagnosis, i.e., those with a blood glucose level of 140-152 mg/dl 2 hours after administration, a fasting glucose level <92 mg/dl, and a blood glucose level <180 mg/dl 1 hour after administration. Group B included patients complying with both the previous and current PTG criteria for a GDM diagnosis. Group C included patients who only met the current PTG criteria for a GDM diagnosis, i.e., those with a fasting blood glucose level of 92-99 mg/dl, a blood glucose level <180 mg/dl 1 hour and <140 mg/dl 2 hours after administration, respectively. RESULTS: Women from group C were characterized by the highest fasting glycaemia in the first trimester of pregnancy (93.0 mg/dL vs. 88.0 mg/dL vs. 83.5 mg/dL, p=0.012) and during the OGTT (p=0.001). Gestational diabetes was diagnosed significantly earlier in patients from group C (23 vs. 26 vs. 26 weeks, p=0.005). The patients from group A significantly less frequently required insulin therapy for proper glycemic control (p=0.035). Women from group A were characterized by lower pre-pregnancy BMI (p=0.001). CONCLUSIONS: Current PTG criteria for diagnosing GDM according to the IADPSG allow for identification of women who often require insulin therapy to achieve proper glycemic control.
