Your first patient, Mr. Morales, was seen by Dr. Clay once before, eight years ago, but was lost to follow-up after that time.

Based on review of the electronic medical record you are able to collect the following information prior to heading into the room to meet Mr. Morales:

Mr. Morales is a 55-year-old Hispanic male, diagnosed with Type 2 diabetes mellitus thirteen years ago after experiencing a 20-pound unintentional weight loss, blurry vision, and nocturia. Diabetes chronic disease management

He was hospitalized six weeks ago with a non-ST elevation myocardial infarction and required three vessel coronary artery bypass grafting. During his admission, he was found to have a reduced ejection fraction of 20%.

He was referred for today’s visit by the cardiologist to focus on optimizing his glycemic control and reducing his risk of the comorbidities associated with poorly controlled Type 2 diabetes mellitus.

His last hemoglobin A1c (HbA1c) was 9.5% eight years ago, and he had microalbuminuria at that time. Diabetes chronic disease management

In particular, cardiovascular disease is the No. 1 cause of mortality for people with diabetes, and one of the top causes of morbidity.

Hypoglycemia, infections, foot ulcers, and amputations are additional causes of morbidity and mortality in patients with diabetes.

The American Diabetes Association publishes annual guidelines to assist in the management of a patient with diabetes.

Remember the large role that the psychosocial aspects of a diabetesRemember the large role that the psychosocial aspects of a diabetes diagnosis play in managementdiagnosis play in management

Non-adherence with medical recommendations could be due to economic, work-related, religious, social, or linguistic barriers to care. Care must be taken to assess the psychosocial status of each person with diabetes at each clinic visit to ensure that barriers to successful diabetes care are minimized.

Question Which of the following does the American Diabetes Association recommend to minimize the risk of cardiovascular disease in patients with diabetes? Select all that apply. Diabetes chronic disease management



The best options are indicated below. Your selections are indicated by the shaded boxes.

A. Smoking cessation

B. Daily aspirin therapy

C. Blood pressure less than 140/90 mmHg (if it can be

achieved without increased treatment burden, a systolic target of < 130

is appropriate in younger, healthier patients)

D. If > 40 years old, regardless of other atherosclerotic

cardiovascular disease risk factors, statin therapy


Answer Comment > The correct answers are A, B, C, D> The correct answers are A, B, C, D

ADA Recommendations to Minimize the Risk of Cardiovascular Disease in Patients with Diabetes Smoking cessationSmoking cessation, daily aspirindaily aspirin, blood pressure controlblood pressure control and lipid controllipid control are all recommended to reduce the risk of cardiovascular disease.Diabetes chronic disease management

Please note that as of 2018, ADA recommendations were published with the older definition of hypertension (140/90). It always takes time before multiple different organizations agree on the same thresholds.

Daily low dose aspirin is recommended for primary prevention of cardiovascular disease in diabetic patients with a 10-year risk of atherosclerotic cardiovascular disease of >10%. It is also recommended for secondary prevention of all diabetic patients with a history of atherosclerotic disease.

Reduction of cardiovascular risk is achieved with a goal of optimal glycemic control, as well as control of many other health factors that raise cardiovascular risk, such as tobacco use, obesity, poorly controlled hypertension, and hypercholesterolemia.

Mr. Morales tells you about his heart attack.Mr. Morales tells you about his heart attack.


You enter the exam room and introduce yourself to Mr. Morales.

“What brought you to the oRce today?” “I had a heart attack about a month ago and had to have open-heart surgery. The heart doctors told me that my heart is weak now. My cardiologist told me that I have to get my blood sugar under control so I don’t have another heart attack. I am here to get down to work.”Diabetes chronic disease management

“Tell me more about that.” “I didn’t come back to see Dr. Clay because my job at the furniture factory wouldn’t give me time off for clinic appointments, and I couldn’t risk losing

my job. I wasn’t checking my blood sugar before my heart attack because the testing strips are so expensive and my supervisor wouldn’t let me off the line to check anyway. Since my surgery, I haven’t gone back to work, and I’ve been checking my sugar before each meal and before bed. The hospital social worker got me two months’ worth of testing strips and lancets before I went home, but I’m going to run out in a couple of weeks. I’m worried that I won’t be able to check anymore.”

He also tells you that while he was in the hospital, they had to use insulin through his vein to keep his blood sugar controlled, and that was very upsetting to him.

Question True or False: In a critically ill medical patients, tight blood sugar control with intravenous insulin therapy, with a goal blood sugar of 80-110 mg/dL, is associated with lower mortality than less tight blood sugar control (e.g. 140-180 mg/dL).Diabetes chronic disease management

A. True

B. False


Answer Comment > The correct answer is B> The correct answer is B

EUectiveness of Intravenous Insulin for Blood Glucose Control Blood sugar control in critically ill patients has been the subject of considerable investigation. Previous research suggested that tight control (80-120 mg/dL) was desirable, but more recent research shows that aggressive blood sugar control can be associated with higher mortality.

Hypoglycemia (serum glucose concentration <70 mg/dL), with rates as high as 40% in some studies, is associated with tight glycemic control. Diabetes chronic disease management


A meta-analysis of 29 controlled trials involving more than 8,000 adult ICU patients showed no difference in in-hospital mortality between the group assigned to tight glucose control versus usual care.

The current recommended blood glucose target for mostThe current recommended blood glucose target for most hospitalized patients is 140 to 180 mg/dL.hospitalized patients is 140 to 180 mg/dL.

MEDICATION REVIEW HISTORY You review Mr. Morales’ medications with him:


metformin 1000 mg twice daily pioglitazone 15 mg daily glipizide 5 mg daily aspirin 81 mg daily clopidogrel 75 mg daily long-acting metoprolol 100 mg daily furosemide 80 mg twice daily lisinopril 20 mg daily amlodipine 10 mg daily ranitidine 150 mg twice daily gabapentin 300 mg twice daily potassium chloride 10 mEq twice daily atorvastatin 80 mg daily Diabetes chronic disease management

Mr. Morales says, “The hospital doctors sent me home on an insulin shot – 40 units in my belly every night before I go to bed. I don’t like giving myself the shot, so sometimes I just don’t, but I take all the rest of my medicines like they told me to.”

He takes out the vial of insulin, and you see that it is insulin glargine.

Which of the following medications should you consider discontinuing in this patient based on your knowledge of his reduced ejection fraction? Choose the single best answer.

A. Pioglitazone

B. Atorvastatin

C. Aspirin

D. Glipizide


Answer Comment > The correct answer is A> The correct answer is A

Thiazolidinediones Pioglitazone (A),Pioglitazone (A), a member of the class of drugs known as thiazolidinediones (TZD), is not recommended for use in patients who have newly developed heart failure and in those with known NYHA Class III and IV heart failure. The same is true for rosiglitazone, another TZD that has been associated with an increased risk of cardiovascular disease. Diabetes chronic disease management

Mechanism of action:Mechanism of action: TZDs are peroxisome proliferator-activated receptor-gamma (PPARgamma) agonists.

Effects:Effects: TZDs decrease insulin resistance, increase glucose uptake in peripheral tissue, decrease hepatic glucose production, decrease vascular inflammation, redistribute visceral adipose tissue peripherally, and preserve beta cell function. Overall, they cause the A1c to decrease by 1% to 1.5%. Hypoglycemia is not associated with this medication class. TZDs have differing effects on lipids. Pioglitazone slightly reduces LDL levels and raises HDL. Rosiglitazone can increase LDL levels.

Side effects:Side effects: The receptors that TZDs activate are ubiquitous and are


abundant in the cells within the renal collecting tubules. Hence, TZDs increase sodium reabsorption, leading to increased water retention. Compared to placebo, all TZDs are associated with a statistically significant increase in edema and weight.

Warnings:Warnings: Care should be used with these agents in patients with liver disease. Serum transaminases greater than 2.5 times the upper limit of normal is a contraindication to initiation of these agents, and a rise to greater than three times the upper limit of normal should lead to their discontinuation. Liver tests should be measured at baseline and periodically while the patient is on this class of medication. Diabetes chronic disease management

Contraindications:Contraindications: The FDA has added a warning to the label of pioglitazone noting an increased risk of bladder cancer after more than one year of treatment. Pioglitazone is now contraindicated in patients with a history of bladder cancer or active bladder cancer. Patients should be counseled to tell their physician if they notice blood in their urine or a red tint to their urine.

No precautions are needed when using aspirin, glipizide, or simvastatin in patients with a reduced ejection fraction.



You continue your interview with Mr. Morales and ask him:

“Have you brought your blood sugar log with you today?” He hands you his blood sugar log proudly. Over the last four weeks, you see that his morning fasting readings are ranging 130-169 mg/dL, including before-lunch readings of 151-247 mg/dL, before-supper readings of 184-211 mg/dL, and before-bed readings of 158-305 mg/dL. There are no recorded readings under 70 mg/dL (3.9 mmol/L).

“Some days you have many readings over 200 mg/dL. Is there anything diUerent going on on those days that you can think of such as eating larger meals?” “Oh, those are the days after I didn’t take my insulin shot. The readings are always higher on those days.”


“Have you had any low blood sugars?” “I feel like I have low blood sugar several times a week, and I eat a Snickers bar because I’m afraid of passing out and going into a coma. I feel like I’m going to die — shaky, sweaty, jittery! I don’t check when I feel this way, I just eat as fast as I can – I can tell when my sugar is low.”

Hypoglycemia It is important at each visit to ask diabetic patients if they have experienced any hypoglycemic symptoms or events that required the assistance of another person.

Often times, when a patient is hypoglycemic, he does not write it down because he is preoccupied treating the hypoglycemia.

When to Refer Patients with Diabetes to an Endocrinologist If a patient is having recurrent or severe hypoglycemia (seizure, coma, or impairment that requires the aid of another person), an endocrinologist should be consulted. Hypoglycemia is defined as a blood glucose <70 mg/dL.

Primary care physicians’ threshold for referral varies across providers. Other conditions that would warrant referral are when a patient’s A1c is 8% more than twice in a 12-month period, despite intensive treatment; for initiation of a complex multiple daily injection insulin regimen; or for initiation of continuous infusion insulin pump therapy.

Question Can patients accurately detect hypoglycemia by symptoms alone?

A. Yes

B. No

Self-Monitoring Glucose: Indications & EUectiveness


Self-Monitoring Glucose: Indications & EUectiveness Effectiveness of Self-Monitoring Blood GlucoseEffectiveness of Self-Monitoring Blood Glucose

Patients should be advised to check their blood sugar if they feel “low” because it is well recognized that people are not able topeople are not able to accurately detect hypoglycemia (blood glucose of < 70 mg/dL)accurately detect hypoglycemia (blood glucose of < 70 mg/dL) by symptoms aloneby symptoms alone. Eating high carbohydrate food to treat perceived hypoglycemia rather than actual hypoglycemia leads to worsened overall glycemic control.

Clinical studies have shown that self-monitoring of blood glucose (SMBG) may improve glycemic control, although for some patients self-monitoring increases depression and anxiety. It is important to evaluate patients’ abilities to use SMBG techniques to ensure they are using accurate data to evaluate their response to therapy and their degree of success in reaching blood-glucose targets. After receiving education, patients can use SMBG data to adjust their activity level, food intake and choice, as well as drug therapy to achieve optimal glycemic control.
