  2. INTRODUCTION- OBJECTIVE • Placentalgrowthfactor (PlGF) secretedbythesyncytiotrophoblast is found in thematernalcirculationbeginning in thesixthweek of gestation. • Placentalgrowthfactor [PlGF] is a placenta-derivedangiogenic protein involved in theregulation of placentalvasculardevelopment[1]. 1- Maynard SE, et al. J ClinInvest 2003;111: 649–58.

  3. PlGF has beenextensivelyinvestigated as a firsttrimesterbiomarkerforpregnancycomplicationsrelatedtoimpairedplacentationsuch as preeclampsiaandbirthweightdeviations[2-4]. • Also, inclusion of serum PlGFimprovestheperformance of first-trimesterscreening test fortrisomy 21 [5]. . 2- Levine RJ, et al.

  4. PreviousstudiesbyOngandSyngelaki et al. foundincreasedserum PlGFlevels in gestationaldiabetes (GDM) [6,7]. • A recentlypublishedstudyalsopresentedsignificantlyhigherfirst-trimesterPlGFvalues in the GDM group[8] . • Anotherrecentstudydidnot finda relationshipbetween PLGF measured at 11–14 weeksandsubsequent GDM among 328 womenrecruitedprospectively[9]. 6- Syngelaki A, et al. Metabolism. 2015;64(11):1485– 9. 7- Ong CY, et al. J ReprodMed. 2004;49(6):477–80. 8- Eleftheriades M, et al. Metabolism 2014; 63: 1419–1425. 9- Mosimann B et al. . FetalDiagnTher. 2016;39:287–91.

  5. However, newer data found thatserum PlGF was decreased in women with diabetes mellitustype 1 and in those with type 2 disease[8]. • At present, these findings remain contradictory. • Therefore,weaimedtoinvestigatetheassociations of maternal serum placentalgrowthfactor (PlGF) levelswithgestationaldiabetesmellitus (GDM). 8- Tsiakkas A, et al. UltrasoundObstetGynecol 2015; 45: 591–598.

  6. MATERIAL-METHODS • Thiscross-sectionalstudywasunderwent in theObstetricsandGynecologyDepartment of Hitit UniversitybetweenMarch, 2015 andSeptember, 2015. • A total of 158 pregnantwomenwerescreenedbetween 24 and 28 weeks of gestation. • All of thelow risk pregnantwomenwereevaluatedwith a 50-g glucosechallenge test (GCT). Womenwith serum glucose ≥ 140 mg/dL at 1 h after GCT weresubjectedto a 100-g oral glucosetolerance test (OGTT).

  7. Pregnantwomenwho met theinclusioncriteriaweredividedintotwogroups; • 76 of the GDM group, • 82 of thecontrolgroup. • Maternal serum concentrations of PlGF, insulinandhomeostasis model assessment-insulin resistance(HOMA-IR) wereassessed.

  8. Vasculogenesisandangiogenesisareessentialforplacentaldevelopmentandthe VEGF family has beenshowntoplay a key role [10]. • A recent meta-analysis of studiesinvestigatingpostpartumplacentalhistologyderivedfrompregnanciescomplicatedby GDM demonstratesthatthere is increasedplacentalvolume, higherincidence of villousimmaturityandincreasedangiogenesis[11]. 10- Geva E, et al. J ClinEndocrinolMetab 2002; 87:4213–4224. 11- Huynh J, et al. Placenta 2015; 36: 101–114.

  9. Particularlythefetoplacentalvasculatureandendotheliumwereshownto be susceptibletohyperglycemia[12]. • Fetalhyperinsulinism as a result of maternalhyperglycemiastimulatesplacentalangiogenesis[13]. • Therefore, an increase in angiogenicmarkerssuch as PlGFmight be a consequence of thesealterations. 12- Cvitic S, et al. BiomedResInt 2014; 2014: 145846. 13- Lassance L, et al. J ClinEndocrinolMetab 2013; 98:e1438–e1447.

  10. CONCLUSION • Werevealedthatthe serum PlGFlevelsweresignificantlyincreasedin pregnantswith GDM. • PlGFseemstohave a role in pathogenesisandearly GDM diagnosis. • Earlyidentificationof women at high risk for GDM could lead to an earlierdiagnosis of the condition and improve the pregnancyoutcomes.
