Can glyburide be advocated over subcutaneous insulin for perinatal outcomes of women with gestational diabetes? A systematic review and meta-analysis.

PURPOSE: To obtain precise findings from published studies about the efficacy and safety of glyburide versus subcutaneous insulin in patients with gestational diabetes mellitus (GDM). METHODS: We searched PubMed, Cochrane Library, Web of Science, and Scopus, up to January 2019, for relevant studies that compared glyburide with subcutaneous insulin for patients with GDM. We extracted maternal and neonatal outcomes from included studies, performed meta-analysis, evaluated heterogeneity, assessed the risk of bias of included studies, and conducted subgroup and sensitivity analyses. RESULTS: A total of 24 studies (11 randomized controlled trials (RCTs) and 13 observational cohort studies) with a total of 24,517 women were included in the present study. The pooled estimate showed that glyburide significantly decreased the need for cesarean section (OR = 0.87, 95% CI [0.82, 0.92], p < 0.0001), fasting blood glucose (MD - 5.63 mg/dL, 95% CI [- 10.97, - 0.28], p = 0.04), and Apgar score at 5 min (MD - 0.30, 95% CI [- 0.36, - 0.23], p < 0.001) than insulin. However, glyburide significantly increased the risk of neonatal hypoglycemia (OR = 1.42, 95% CI [1.03, 1.95], p = 0.03) and neonatal intensive care unit admission duration (NICU) (MD 4.26 days, 95% CI [2.65, 5.86], p < 0.01) compared to insulin. The overall results did not favor either group in terms of macrosomia (OR = 1.14, 95% CI [0.92, 1.41], p = 0.25) and large for gestational age (LGA) (OR = 1.38, 95% CI [0.99, 1.92], p = 0.06). While subgroup analysis of RCTs showed that maternal hypoglycemia and LGA rates were significantly higher in glyburide than insulin and cesarean section rates were comparable between both compared groups. CONCLUSION: Our study suggests that glyburide is an effective and well-tolerated drug compared to insulin in the management of women with GDM, provided neonates are monitored for hypoglycemia and Apgar score. In addition, glyburide was associated with lower cesarean sections, which may add to the potential clinically benefits of glyburide compared to insulin.

Association of miRNA - 320 expression level and its target gene endothelin-1 with the susceptibility and clinical features of polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder characterized by obesity, hyperandrogenism, and insulin resistance (IR). MicroRNAs (miRNAs) are small noncoding RNA associated with ovarian follicle development and female fertility. The objective of this study was to investigate the role of miRNA- 320 and its target gene endothelin-1 (ET-1) as a noninvasive biomarker of PCOS and to evaluate its possible relationship with IR as well as clinic-morphological features of PCOS. METHODS: Case-control study enrolled 60 patients with PCOS and 40 control group. We subdivided our PCOS women according to homeostasis model assessments of insulin resistance (HOMA-IR) to PCOS women with and without IR.ET-1 levels were measured by ELISA. We estimated the serum expression level of miRNA- 320 by real-time polymerase chain reaction. RESULTS: Our results revealed that serum miR-320 expression level was lower in PCOS patients compared to controls, in particular, PCOS women with IR. Moreover, it was negatively correlated to its target gene; ET-I as well as fasting serum insulin (FSI), HOMA-IR, PCOS phenotype; hirsutism score, ovarian volume and antral follicle count (AFC). In the PCOS group, linear regression analysis revealed that only hirsutism and HOMA-IR was the main predictor of expression levels of miRNA - 320 among other clinical and laboratory biomarkers of PCOS. The sensitivity and specificity of serum miR-320 expression levels in diagnosis PCOS was 80, and 97.5% respectively. CONCLUSION: The Expression serum levels of miR-320 were lower in PCOS compared to control and it could be a noninvasive diagnostic biomarker of PCOS.
