,EP is a 38-year-old female patient that comes in for diabetes education and
management. She was diagnosed 12 years ago and states lately she is not able to
control her diet although she continues a 1600 calorie diet with appropriate daily
carbohydrate intake (per dietitian prescription) and walks 40 minutes every day of the
week. She states compliance with all medications. She denies any history of
hypoglycemia despite being able to identify signs and symptoms and describe
appropriate treatment strategies.
PMH: T2DM, HTN, obesity, depression, s/p thyroidectomy due to thyroid cancer
FmHx: Noncontributory
SHx: (−) Smoking, alcohol use, past marijuana use while in high school
Medications: Metformin 850 mg tid, glipizide 20 mg bid, lisinopril 20 mg daily, sertraline
100 mg daily, multivitamin daily
Vitals: BP 128/82 mg Hg; P 72 beats/min; BMI 31 m/kg2
Laboratory test results: Na 134 mEq/L, K 5.4 mEq/L, Cl 106 mEq/L, BUN - CORRECT
ANSWERS-Exenatide - Exenatide (Bydureon) once weekly has been able to
demonstrate weight loss and decrease A1C% by 0.7% to 1.2% in clinical trials; however
it is contraindicated for EP due to the self-reported history of thyroid cancer.
,Dapagliflozin - Dapagliflozin (Farxiga) is contraindicated in this patient due to
hyperkalemia which could be made worse by this drug. The package insert does not
indicate a specific potassium concentration cut off to no longer use this medication;
however, there are better choices in this patient.
Sitagliptin - Sitagliptin (Januvia) is able to obtain an A1C goal of less than 7% based on
clinical trials and currently the patient does not have any cautionary objective measures
to not use this medication. DPP-IV inhibitors are weight neutral. DPP-IV inhibitors can
be used in patients taking sulfonylureas; however, it may be recommended to reduce or
stop the sulfonylurea dose.
Acarbose - Acarbose (Precose) is not recommended for initial management and is
associated with significant GI side effects. More information would be needed regarding
fasting and post-prandial numbers. In addition, adding acarbose would only lower A1c
by 0.8% at best and therefore would not achieve the desired A1C goal of <7%
JR is a 68-year-old African American man with a new diagnosis of T2DM. He was
classified as having prediabetes (at risk for developing diabetes) 5 years before the
diagnosis and has a strong family history of type 2 diabetes. JR's blood pressure was
, 150/92 mm Hg. His laboratory results revealed an A1C of 8.1%, normal cholesterol
panel, and normal renal/hepatic function were noted with today's laboratory test results.
Past medical history: Hypertension (diagnosed 4 y ago) Hyperlipidemia (diagnosed 2 y
ago) Pancreatitis (idiopathic) (acute hospitalization 3 y ago)
Family history: Type 2 diabetes
Medication: HCTZ 25 mg daily, simvastatin 10 mg daily
Allergies: SMZ/TMP
Vitals: BP: 150/92 mm Hg P: 78 beats/min RR: 12 rpm Waist Circumference: 46 in
Weight: 267 lb Height: 5 ′ 6 ″ BMI: 43.1 kg/m 2
Despite improvements in the past six weeks due to lifestyle changes and exercise, drug
therapy is to be started for JR's diabet - CORRECT ANSWERS-Metformin is the drug of
choice recommended for most patients with diabetes in addition to lifestyle
modifications assuming no contraindications or intolerabilities are present upon
evaluation. Metformin has also shown to provide positive weight neutral/loss effects in
obese patients. It is crucial to know the renal status of patients commencing metformin
therapy to limit the risk of lactic acidosis (JR is without contraindication).
