Objective: To evaluate glycemic control and pregnancy outcomes among pregnant women with severe insulin resistance treated with 500 units/mL concentrated insulin., Methods: Retrospective analysis of gravid women with severe insulin resistance (need for greater than 100 units of insulin per injection or greater than 200 units/d) treated with either 500 units/mL concentrated insulin or conventional insulin therapy. We performed a two-part analysis: 1) between gravid women treated with and without 500 units/mL concentrated insulin; and 2) among gravid women treated with 500 units/mL concentrated insulin, comparing glycemic control before and after its initiation., Results: Seventy-three pregnant women with severe insulin resistance were treated with 500 units/mL concentrated insulin and 78 with conventional insulin regimens. Patients treated with 500 units/mL concentrated insulin were older and more likely to have type 2 diabetes mellitus. Average body mass index was comparable between both groups (38.6 compared with 40.4, P=.11) as were obstetric and perinatal outcomes and glycemic control during the last week of gestation. Within the 500 units/mL concentrated insulin cohort, after initiation of this medication, fasting and postprandial blood glucose concentrations improved. However, the rates of blood glucose values less than 60 mg/dL and less than 50 mg/dL were higher in the 500 units/mL concentrated insulin group after initiation than before, 4.8% compared with 2.0% (P<.01) and 2.0% compared with 0.7% (P<.01), respectively., Conclusion: The use of 500 units/mL concentrated insulin in severely obese insulin-resistant pregnant women confers similar glycemic control compared with traditional insulin regimens but may increase the risk of hypoglycemia., Level of Evidence: II.

The purpose of this study was to describe the neonatal characteristics and outcomes of infants who were born during the 2009 H1N1 influenza pandemic. A prospective cohort of pregnant women with influenza-like illness (ILI) was enrolled between the months of June 2009 and March 2010. Neonatal characteristics, complications, and outcomes were recorded. Forty-five women were included in the study. Birth outcomes were available in 41 cases; 16 women had 2009 H1N1 infection, and the remaining 25 women who tested negative were included in the ILI group. Live births were similar in both groups. Average gestational age at delivery was >39 weeks; Apgar scores and cord gas pH values were similar. Birthweights in the 2009 H1N1 group were on average 285 g lower (3186 vs 3471 g; P = .04). Three infants were admitted to the neonatal intensive care unit. In this cohort, 2009 H1N1 infection during pregnancy was associated with a lower birthweight when compared with ILI in pregnancy., (Copyright © 2011 Mosby, Inc. All rights reserved.)
