The United Kingdom Prospective Diabetes Study (UKPDS) showed that intensive therapy (mean A1C value of 7%) with OHAs or insulin resulted in a decreased risk of microvascular complications compared with conventional therapy with diet (mean A1C value of 7.9%) at the end of the study 1997. According to UKPDS 0.9% reduction in A1C at 10 years was associated with a ___ reduction in microvascular endpoints.
- A.
5%
- B.
15%
- C.
25%
- D.
35%
Correct Answer
C. 25%Explanation
The UKPDS study found that a 0.9% reduction in A1C levels at 10 years was associated with a 25% reduction in microvascular endpoints. This means that for every 0.9% decrease in A1C levels, there was a 25% decrease in the risk of developing microvascular complications such as diabetic retinopathy, nephropathy, and neuropathy. This highlights the importance of achieving and maintaining good blood sugar control in order to prevent these complications.Rate this question:

According to a meta-analysis of intensive glucose-lowering trials, the benefit of different interventions with 5 year treatment, which of the following results in better reduction of CV events?
- A.
Reduction of systolic BP (4 mmHg)
- B.
Reduction of HbA1C (0.9%)
- C.
Reduction of LDL cholesterol (38.6 mg/dL)
- D.
All of the above
Correct Answer
A. Reduction of systolic BP (4 mmHg)Explanation
According to a meta-analysis of intensive glucose-lowering trials, the intervention that results in better reduction of CV events is the reduction of systolic BP (4 mmHg). This means that lowering systolic blood pressure by 4 mmHg has a greater impact on reducing cardiovascular events compared to reducing HbA1C levels or LDL cholesterol levels.Rate this question:

In elderly long-standing diabetes with comorbidities the HBA1C goal is
- A.
6-6.5%
- B.
6.5-7%
- C.
7-7.5%
- D.
7.5-8%
Correct Answer
D. 7.5-8%Explanation
In elderly patients with long-standing diabetes and comorbidities, the HbA1C goal is set at 7.5-8%. This higher range is chosen to avoid the risk of hypoglycemia, which can be particularly dangerous for older individuals. Additionally, elderly patients may have other health conditions that make it difficult to achieve tight glycemic control. Therefore, a slightly higher HbA1C target is considered more appropriate in this population to balance glycemic control with the potential risks.Rate this question:

According to East-West Study
- A.
Patients with DM but no CHD experience a higher rate of MI as patients without DM but with CHD
- B.
Patients with DM but no CHD experience a lower rate of MI as patients without DM but with CHD2
- C.
Patients with DM but no CHD experience a similar rate of MI as patients without DM but with CHD
Correct Answer
C. Patients with DM but no CHD experience a similar rate of MI as patients without DM but with CHDExplanation
The answer suggests that patients with diabetes (DM) but no coronary heart disease (CHD) have a similar rate of myocardial infarction (MI) as patients without diabetes but with CHD. This means that the presence of diabetes alone does not significantly increase the risk of MI compared to having CHD without diabetes.Rate this question:

A 50 year old man with history of myocardial infarction has new onset type 2 diabetes with HbA1C 8%. You are considering drug treatment, the first drug to be considered is
- A.
Metformin
- B.
Gliptins
- C.
SGLT2 inhibitor
- D.
GLP-1 agonists
Correct Answer
A. MetforminExplanation
Metformin is the first-line drug treatment for type 2 diabetes, especially in patients with a history of myocardial infarction. It is recommended as the initial therapy by various guidelines due to its efficacy in reducing blood glucose levels, its safety profile, and its potential cardiovascular benefits. Metformin works by decreasing glucose production in the liver, improving insulin sensitivity, and reducing glucose absorption in the gut. It is also associated with weight neutrality or even weight loss, which is beneficial for patients with diabetes and cardiovascular disease. Therefore, considering the patient's history and the recommended treatment guidelines, metformin is the appropriate first drug to be considered in this case.Rate this question:

According to ADA guidelines the following combination of drugs is not recommended in the treatment of T2D
- A.
DPP-4 inhibitors and GLP-1 agonists
- B.
GLP-1 agonists and SGLT2 inhibitors
- C.
SGLT2 inhibitors and TZDs
- D.
DPP-4 inhibitors and TZDs
Correct Answer
A. DPP-4 inhibitors and GLP-1 agonistsExplanation
The combination of DPP-4 inhibitors and GLP-1 agonists is not recommended in the treatment of T2D according to ADA guidelines. This is because both of these medications work to increase the levels of GLP-1, which can lead to an increased risk of hypoglycemia. Additionally, there may be an increased risk of gastrointestinal side effects when these two medications are used together. Therefore, it is advised to avoid this combination in the treatment of T2D.Rate this question:

The following drugs have shown cardiovascular benefits by decreasing MACE
- A.
Metformin and insulin
- B.
DPP4 inhibitors and Metformin
- C.
SGLT2 inhibitors and GLP-1 agonists
- D.
SGLT2 inhibitors and long acting GLP-1 agonists
Correct Answer
D. SGLT2 inhibitors and long acting GLP-1 agonistsExplanation
SGLT2 inhibitors and long-acting GLP-1 agonists have shown cardiovascular benefits by decreasing MACE (Major Adverse Cardiovascular Events). These drugs work by different mechanisms to improve cardiovascular outcomes. SGLT2 inhibitors reduce the reabsorption of glucose in the kidneys, leading to decreased blood glucose levels and improved cardiovascular function. Long-acting GLP-1 agonists increase insulin secretion, decrease glucagon secretion, and slow down gastric emptying, resulting in improved glycemic control and cardiovascular health. The combination of these two drugs has been found to be effective in reducing MACE and improving cardiovascular outcomes in patients.Rate this question:

- A.
GLP1 agonists and SGLT2i
- B.
α-glucosidase inhibitors and Linagliptin
- C.
Linagliptin and Dapagliflozin
- D.
TZDs and Saxagliptin
Correct Answer
D. TZDs and SaxagliptinExplanation
TZDs (thiazolidinediones) and Saxagliptin are not to be used in patients with type 2 diabetes (T2D) and congestive heart failure (CHF). Thiazolidinediones can cause fluid retention and worsen heart failure symptoms, while Saxagliptin has been associated with an increased risk of heart failure. Therefore, these drugs should be avoided in T2D patients with CHF to prevent exacerbation of their heart condition.Rate this question:

Which of the following drugs can be used in patients with CKD (eGFR < 30ml/min)
- A.
Metformin
- B.
Glibenclamide
- C.
Linagliptin
- D.
Empagliflozin
Correct Answer
C. LinagliptinExplanation
Linagliptin is the correct answer because it is a dipeptidyl peptidase-4 (DPP-4) inhibitor that is not renally excreted. This means that it does not require dose adjustments or pose a risk of accumulation in patients with chronic kidney disease (CKD) and an estimated glomerular filtration rate (eGFR) of less than 30 ml/min. Metformin is contraindicated in patients with an eGFR below 30 ml/min due to the risk of lactic acidosis. Glibenclamide and empagliflozin also require dose adjustments or are contraindicated in patients with CKD.Rate this question:

Which of the following drug/drugs on long term treatment requires least number of patients to prevent one CV death (NNT) in T2D?
- A.
Statins
- B.
Antihypertensives
- C.
Aspirin
- D.
Empagliflozin
Correct Answer
D. EmpagliflozinExplanation
Empagliflozin requires the least number of patients to prevent one cardiovascular (CV) death in patients with type 2 diabetes (T2D). This suggests that empagliflozin has a higher efficacy in preventing CV death compared to the other options listed (statins, antihypertensives, and aspirin). The NNT (number needed to treat) is a measure of the effectiveness of a treatment, and a lower NNT indicates a more effective treatment. Therefore, empagliflozin is the most effective option for preventing CV death in T2D patients.Rate this question:
