From the Guidelines
I would recommend that the 73-year-old patient with a GFR of 47, blood glucose of 112, albumin/globulin ratio of 2.1, and RBC count of 4.13, and chronic hypothyroidism, be managed with a comprehensive approach that includes dietary changes, regular monitoring of kidney function, blood glucose, and thyroid levels, and optimization of their hypothyroidism treatment. Their GFR of 47 indicates stage 3a chronic kidney disease, which requires careful management to prevent progression to more advanced stages 1. Their blood glucose of 112 is slightly elevated, suggesting prediabetes, and they should be advised to maintain a healthy diet and lifestyle to prevent the development of diabetes 1. The albumin/globulin ratio of 2.1 is normal, indicating adequate protein balance. Their red blood cell count of 4.13 is slightly low, which could be related to their kidney function or chronic hypothyroidism. For their hypothyroidism, we should ensure they're taking their thyroid medication (such as levothyroxine) regularly, typically once daily on an empty stomach. I recommend dietary changes including reduced sodium (less than 2,300mg daily), moderate protein intake (0.8g/kg body weight), and limited processed foods, as suggested by the 2020 KDIGO clinical practice guideline for diabetes management in chronic kidney disease 1. They should monitor blood pressure regularly, aiming for below 130/80. We'll need to check thyroid levels (TSH, free T4) to ensure optimal treatment of hypothyroidism, which can affect kidney function if poorly controlled. Regular follow-up every 3-6 months is important to monitor kidney function, blood glucose, and thyroid levels. They should stay well-hydrated but avoid excessive fluid intake, and we'll review their medications to ensure none are worsening kidney function. This approach addresses both their kidney function concerns and manages their hypothyroidism to prevent further complications, in line with the National Kidney Foundation practice guidelines for chronic kidney disease evaluation, classification, and stratification 1. Key aspects of their care include:
- Dietary modifications to reduce sodium and protein intake
- Regular monitoring of kidney function, blood glucose, and thyroid levels
- Optimization of hypothyroidism treatment
- Maintenance of a healthy lifestyle to prevent the development of diabetes and cardiovascular disease
- Regular follow-up to adjust their treatment plan as needed.

From the Research
Patient Information
- Age: 73 years
- GFR: 47
- Fasting glucose: 112 mg/dL
- Albumin/globulin ratio: 2.1
- RBC: 4.13
- Chronic hypothyroidism
Explanation of Lab Results
- The patient's GFR of 47 indicates impaired kidney function, which may be related to their chronic hypothyroidism 2.
- The fasting glucose level of 112 mg/dL is considered impaired fasting glucose, but studies have shown that this may not be directly associated with the development of chronic kidney disease in non-diabetic populations 3, 4.
- The albumin/globulin ratio of 2.1 is within normal limits.
- The RBC count of 4.13 is slightly below normal, which may be related to the patient's hypothyroidism, as thyroid hormones stimulate the proliferation of erythrocyte precursors 5.
Plan
- Monitor the patient's kidney function and adjust their treatment plan as needed to slow the progression of kidney disease.
- Manage the patient's hypothyroidism with medication and regular check-ups to prevent further kidney damage.
- Consider the patient's impaired fasting glucose level when developing a treatment plan, but do not necessarily attribute their kidney disease to this factor.
- Take a comprehensive patient history to identify any other potential factors contributing to the patient's kidney disease and develop a personalized treatment plan 6.
