From the Director

DUKE.RESEARCH.NIGHT.03 (1)Doctoberfest begins this week! We are looking forward to a month of building community, within and outside the residency program.  We will kickoff on Wednesday with our first "We Care Wednesday"..thank you to Residency Council Chairs Nick and Katie for helping us choose our charitable donation sites.  Trivia starts Wednesday as well, so keep a lookout in your emails for the (almost) daily questions.  I have my re-certification for ID at the end of the month, so I will do my best not to make it entirely ID themed!

Kudos this week go to the MICU team of Myles Nickolich, Amy Lee, Jon Buggey, Jon Hansen, Adva Eisenberg and Jason Zhu from Talal Dahhan and Craig Rackley.  7 weeks with a STELLAR crew.  Also kudos to Mike Woodworth and Nick Wisnoski for their excellent SAR talks.  Thank you also to Matt Hitchcock for encouraging Martin Society to get their flu shots.  However….Kerby has done it again! The Kerby Society maintains their title of the Fastest Flu Shots in the Program…see the photo of Kerby leader Heather Whitson and her kids getting shots (no tears!) as well as the incredible team spirit of our APD for QI and Patient Safety Lish Clark... makes all of those other flu shot posters look bad! Congratulations to Kerby Society as well as to Lish and Alan on their wedding this past weekend.

Regardless of winning or not, GO GET THAT FLU SHOT! 




This weeks pubmed from the program goes to Nick Rohrhoff….Rohrhoff N, Vavalle JP, Halim S, Kiefer TL, Harrison JK. Current status of percutaneous PFO closure. Curr Cardiol Rep. 2014 May;16(5):477.

Have a great week and HAPPY DOCTOBERFEST!




What Did I Read This Week?

Submitted by: Alex Cho, MD, MBA

Feinglos MN, Thacker CR, Lobaugh B, DeAtkine DD, McNeill DB, English JS. Combination insulin and sulfonylurea therapy in insulin-requiring type 2 diabetes mellitus. Diabetes Research & Clinical Practice 1998;39(3):193-99. (



It is not uncommon for patients, particularly very obese patients with Type 2 diabetes, to require high daily doses of insulin, sometimes totaling >100 U a day. However, the administration of large boluses of exogenous insulin may have its own deleterious effects, including weight gain from appetite stimulation and even atherosclerosis from the resulting hyperinsulinemic state. Thus, combinations of therapies that can reduce a patient’s insulin total insulin requirement would appear to be desirable, and may actually lead to superior control over time.

As a result, the combination of certain oral agents (i.e., metformin) with insulin in general has also become commonplace, but as the slow emergence of the use of newer GLP-1 agonists alongside long-acting insulins suggests, these combinations are not necessarily self-evident.

In this classic RCT conducted right here at Duke, Drs Feinglos, McNeill and colleagues sought to address the very important safety and efficacy questions associated with the use of insulin secretagogues such as glipizide alongside NPH and regular insulin – a combination that may strike some as odd, and perhaps potentially unsafe, but presents for our uninsured patients at the DOC a more affordable option, potentially, than even glargine insulin.


“To determine the effect(s) on glucose control, insulin dose, and circulating insulin levels of the addition of a sulfonylurea (glipizide) to the treatment regimen of patients with insulin-requiring type 2 diabetes mellitus.”


Design – Randomized, double-blind, placebo-controlled, crossover clinical trial

Patient Population – Patients were recruited at large from the Duke University Medical Center and Durham community. They were majority female, with a mean age of 56, mean BMI was 32.7, mean total daily insulin dose was 80.8 U, and mean glycated hemoglobin was 12.1%.

Intervention / Control – Participants were assigned to one of two conditions: current insulin regimen + glipizide vs. current insulin regimen + placebo, for an initial 3-month treatment period. This was followed by a one-month “wash-out” period, prior to initiating a second 3-month treatment period, with crossover to the other study drug (glipizide vs. placebo). Participants were hospitalized (in the Duke Clinical Research Unit) at the beginning and end of each three-month treatment period for initiation of treatment, measurements, and titration of insulin regimens; followed by weekly telephone calls and monthly outpatient visits.

Regimens were titrated based on patients response to therapy, resulting in glipizide doses from 5 to 40mg daily, and 1-3 NPH and regular insulin injections daily, with total daily doses ranging from 40 to 210 U.

Blinding – Blinded

Analysis – Repeated measures multi-factor analysis of variance design, which included the sequence of treatment conditions as a factor. Analysis limited to the 29 patients who demonstrated a significant C-peptide response to a test meal.

Outcomes – Fasting plasma glucose, mean 24-hour plasma glucose, glycated hemoglobin, total daily insulin dose, free insulin, BMI.


Patients were blinded and randomized, with a wash-out period in-between treatment conditions. They were also very intensively followed. Overall numbers were small, but the crossover condition guaranteed the treatment groups were more or less identical. A subset of patients was selected for analysis based on biological factors (production of endogenous insulin). The effect of treatment sequence was assessed and found not to be a significant factor.


“The fasting plasma glucose in the I+G arm was 6.8 (121.8 mg/dl) vs. 8.7 mmol/L (156.0 mg/dl) in the I+P arm, P<0.001. Mean plasma glucose over 24 hours was 9.8 (176.9 mg/dl) for I+G vs. 11.3 mmol/L (203.8 mg/dl) for I+P, P<0.00l. Glycated hemoglobin was significantly different (9.8 I+G vs. 11.4% I+P, P<0.008). The total daily insulin dose required was significantly lower with I+G (69.1 vs. 87.3 U, P<0.0005). However, there were no significant differences in free insulin levels.” BMI was also not statistically different between the two groups. Sixty-nine episodes of mild hypoglycemia were recorded, with only six instances of moderate symptomatic hypoglycemia, and only one of these required assistance from another individual.


The results of this well-done RCT show that for patients with insulin-requiring diabetes, the combination of a sulfonylurea and insulin can lead to lower total insulin requirements and improved control, and can be safely administered. An important caveat is that in order for sulfonylureas to be effective, a patient still has to be making their own endogenous insulin (this is also true for the newer GLP-1 agonists); which suggests that this option be considered relatively early in a patient with Type 2 diabetes whose insulin requirements appear to be rapidly accelerating.

One particular use case Dr Feinglos offers would be for patients whose sugars appear to spike in the early AM, to combine bedtime NPH and an oral sulfonylurea with breakfast. One also wonders if the results of this study and others that have demonstrated the long-term superiority of metformin + insulin regimens vs. insulin-only ones also suggest that closely monitored “triple therapy,” might not only be possible, but preferable.

Bottom Line:
For patients with insulin-requiring diabetes who still make their own insulin, the combination of a sulfonylurea and insulin appears to lead to lower total insulin requirements and improved control. This regimen has the added benefit for uninsured or low-income patients of being considerably more affordable.


Clinic Corner

Ambulatory Clinic Corner

Interested in doing a QI or research project in one of the continuity clinics?

Just wanted to advertise the availability of a couple of different data sets from your clinics for possible resident projects. In VA PRIME, Sonal Patel worked with NC State industrial engineering professor Javad Taheri to gather time-stamp data on clinic workflow; and produce modeling of the different steps in the patient visit. This work has informed some of the staffing requests that Sonal has made for PRIME, but could potentially answer other questions as well. Contact Sonal for more information.

At the DOC, third-year Duke medical student and MPP candidate Mark Dakkak has helped construct a database of over 250 clinical and other variables on the over 4000 patients who receive their primary care there, plus AHRQ and other “groupers” that allow the categorization of patients into relevant groups. Contact Alex Cho for more information.
