From the Guidelines
For a 76-year-old patient with an elevated Hemoglobin A1C (HbA1C) level of 6.8% and an alkaline phosphatase (alk phos) level of 108, the initial management should include metformin starting at 500 mg daily with meals, gradually increasing to 1000 mg twice daily as tolerated, unless contraindicated by renal impairment (avoid if eGFR <30 ml/min) 1.
Management of Diabetes and Alkaline Phosphatase Elevation
The patient's HbA1C level indicates the need for intervention to manage diabetes, while the elevated alkaline phosphatase level requires further investigation to determine its cause.
- Lifestyle modifications are crucial and include a Mediterranean diet, moderate exercise (30 minutes walking 5 days weekly), and weight management.
- For elderly patients, a less stringent HbA1C target of 7.5-8.0% is appropriate to minimize hypoglycemia risk 1.
- The elevated alkaline phosphatase requires investigation with liver function tests, gamma-glutamyl transferase, and imaging studies such as abdominal ultrasound to determine if the source is hepatic or bone-related.
Investigation of Alkaline Phosphatase Elevation
If the alkaline phosphatase elevation is hepatic in origin, medication review is crucial to identify potential drug-induced liver injury.
- If bone-related, vitamin D levels should be checked and supplementation provided if deficient (typically 1000-2000 IU daily) 1.
Monitoring and Follow-Up
Regular monitoring of both conditions is necessary, with HbA1C checked every 3 months until stable and alkaline phosphatase monitored based on the underlying cause.
- This dual approach addresses the diabetes while investigating the source of the alkaline phosphatase elevation to ensure comprehensive care for this elderly patient 1.

Management Options for a 76-year-old Patient with Elevated HbA1C and Alkaline Phosphatase
The patient's elevated Hemoglobin A1C (HbA1C) level of 6.8% and alkaline phosphatase (alk phos) level of 108 require careful consideration of management options.
- HbA1C Management: According to the American Diabetes Association guidelines 2, for older adults with diabetes, the target HbA1C level should be individualized based on comorbid health status. For a 76-year-old patient, an HbA1C level of 6.8% may be considered relatively high, and management options may include adjusting medication, diet, and exercise to achieve a more optimal level.
- Alkaline Phosphatase Management: Elevated alkaline phosphatase levels can be associated with various conditions, including bone and liver diseases 3, 4. However, in this case, the patient's alkaline phosphatase level is only slightly elevated, and further evaluation may be necessary to determine the underlying cause.
- Association between HbA1C and Alkaline Phosphatase: There is limited evidence to suggest a direct association between HbA1C and alkaline phosphatase levels. However, studies have shown that elevated alkaline phosphatase levels can be associated with increased mortality and hospitalizations in older adults with diabetes 5.
- Individualized Treatment Goals: The patient's treatment goals should be individualized based on their unique health status, taking into account their age, comorbidities, and other factors. According to a study published in BMJ Open Diabetes Research & Care 6, individualized treatment goals can help balance the risks and benefits of treatment and improve outcomes for older adults with diabetes.
Considerations for Older Adults with Diabetes
When managing a 76-year-old patient with diabetes, it is essential to consider the following factors:
- Comorbid Health Status: The patient's comorbid health status should be taken into account when determining treatment goals and management options 2.
- Medication Use: The patient's medication use, including glucose-lowering medications, should be carefully evaluated and adjusted as necessary to achieve optimal glycemic control 2.
- Lifestyle Modifications: Lifestyle modifications, such as diet and exercise, can play an essential role in managing diabetes and achieving optimal glycemic control 6.
