insulin--isophane and Infant--Newborn--Diseases

The prevalence of diabetes in women of childbearing age is increasing. As such, the number of pregnancies complicated by diabetes will inevitably increase. New insulin analogues such as the long-acting analogue insulin glargine may represent beneficial treatment options in pregnancy by ensuring that patients achieve excellent glycemic control without risk of maternal hypoglycemia.. To determine the fetal safety of insulin glargine use in the treatment of diabetes in pregnancy compared with NPH insulin therapy.. A systematic review and meta-analysis was performed of all original human studies that reported neonatal outcomes among women with pregestational or gestational diabetes who were managed with either insulin glargine or NPH insulin during pregnancy. A systematic literature search was conducted using MEDLINE, EMBASE, CINAHL, the Cochrane Central Register for Controlled Trials database, and Web of Science from 1980 to June 1, 2010. Outcomes included large size for gestational age, macrosomia, neonatal hypoglycemia, neonatal intensive care unit admissions, birth trauma, congenital anomalies, preterm delivery, perinatal mortality, respiratory distress, and hyperbilirubinemia. Relative risk ratios and weighted mean differences were computed with 95% confidence intervals.. Eight studies reporting on a total of 702 women with pregestational or gestational diabetes in pregnancy treated with either insulin glargine (n = 331) or NPH insulin (n = 371) met the inclusion criteria. There were no statistically significant differences in the occurrence of fetal outcomes studied with the use of insulin glargine compared to NPH insulin.. No evidence has been documented for increased adverse fetal outcomes with the use of insulin glargine in pregnancy compared to the use of NPH insulin. These results increase the choices for women requiring basal insulin therapy in pregnancy.

To determine whether basal insulin analogs reduce the rate of composite neonatal morbidity compared with neutral protamine Hagedorn (NPH) in women with type 2 diabetes mellitus (T2DM).. This was a retrospective cohort study of women with T2DM and singleton pregnancy at a single tertiary center. Primary outcome was a composite neonatal morbidity of any of the following: shoulder dystocia, large for gestational age, neonatal intensive care unit admission, neonatal hypoglycemia, or respiratory distress syndrome. Secondary outcomes were rates of maternal hypoglycemic events, hypertensive disorders, preterm birth, and primary cesarean delivery. Adjusted relative risk (aRR) and 95% confidence intervals (CI) were calculated.. Of 233 women with T2DM that met the inclusion criteria, 114 (49%) were treated with basal insulin analogs and 119 (51%) with NPH. The rate of composite neonatal morbidity was similar between groups (73 vs. 60%; aRR: 1.18; 95% CI: 0.92-1.51). There were no differences in the rates of maternal adverse outcomes between the groups. Basal insulin analog was associated with a lower rate of primary cesarean delivery as compared with NPH (21 vs. 36%; aRR: 0.44; 95% CI: 0.25-0.78).. Among pregnant women with T2DM managed with either basal or NPH insulin regimen, the rates of composite neonatal morbidity and maternal complications were similar.

We report a rare case of permanent neonatal diabetes (PND) due to insulin (INS) gene mutation in a 51-month-old girl who presented with hyperglycemia in the neonatal period. Mutational analysis of KCNJ11 and INS was performed and this detected a novel heterozygous c.38T>G (p.Leu13Arg) INS de novo mutation. The non-conservative change substitutes the highly conserved L(13) residue within the hydrophobic core region of the preproinsulin signal peptide. Given the frequent tendency of heterozygous INS mutations to exhibit dominant negative disease pathogenesis, it is likely that the mutant preproinsulin perturbed the non-mutant counterpart progression and processing within the β-cells, and this resulted to a permanent form of congenital diabetes.

The effects of glargine insulin therapy in pregnancies are not well established. We compared maternal and neonatal outcomes of women with pregestational and gestational diabetes treated with glargine or NPH insulin.. A prospective cohort study was conducted analyzing outcomes from 56 women with pregestational and 82 with gestational diabetes treated with either insulin regimen.. Comparisons were performed among 138 women: 56 with pregestational and 82 with gestational diabetes. In relation to maternal complications, worsening of retinopathy and nephropathy, preeclampsia, micro and macroalbuminuria, and all kinds of hypoglycemia were found higher in women with pregestational diabetes NPH-treated vs. glargine-treated. In women with gestational diabetes NPH-treated, it was observed increased incidence of prepregnancy and new-onset pregnancy hypertension, micro and macroalbuminuria, as well as mild and frequent hypoglycemia, compared to glargine-treated. Among the neonatal outcomes, 1-min Apgar score <7, necessity of intensive care unit and fetal death in pregestational, while jaundice and congenital malformations in gestational diabetes, respectively, were more frequently observed in infants born to NPH-treated, compared to glargine-treated.. Glargine use during pregnancy from preconception through delivery, showed to be safe since it is associated with decreased maternal and neonatal adverse outcomes compared with NPH insulin-treated patients.
