My name is Fernando Florido and I am a GP in the United Kingdom. With this episode I am starting a new series on Diabetes Guidelines in Practice, looking at how the guidelines could apply to randomly selected clinical cases. By way of disclaimer, remember that guidelines are there to be interpreted and applied using your clinical judgement. What I am doing here is sharing with you what my interpretation would be in this case. It does not mean that it is the only way, or indeed the best way to treat any individual patient.

My name is Fernando Florido and I am a GP in the United Kingdom.With today’s episode I am starting a new series on Diabetes Guidelines in Practice, looking at how the guidelines could apply to randomly selected clinical cases. By way of disclaimer, remember that guidelines are there to be interpreted and applied using your clinical judgement. I am not giving medical advice here and what I am only doing is sharing with you what my interpretation of the guideline would be in this case. It does not mean that it is the only way, or indeed the best way to treat any individual patient. So, you must always apply your clinical judgement at all times. I will also say that I will only focus on the pharmacological treatment of type 2 diabetes. By all means, we will need to advise about diet, exercise, lifestyle etc, but this will not be addressed in these episodes.Remember that there is also a podcast version of these videos so have a look in the description below.Remember that there is also a Youtube version of these episodes so have a look in the episode description.Right, so let’s get started and let’s generate our random patient. For that we are going to spin a random wheel: Right, so we have an 85-year-old man, newly diagnosed with type 2 diabetes who is poorly controlled with an HbA1c of 65 mmols or 8.1%, who also has heart failure and CKD stage 3b with an eGFR of 32. In addition, he is underweight, even possibly malnourished to some degree. Right, we are going to look at the guidelines and how to apply them. Although I will focus on the NICE guideline, in this case my interpretation and the outcome would be exactly the same if you follow the EASD recommendations or the ADA guideline.So, what does NICE say that we should do? Firstly, we need to consider if rescue therapy is necessary because, for symptomatic hyperglycaemia, we will need to consider insulin or a sulfonylurea and review when blood glucose control has been achieved. So, we are going to assume that he is well and that he has no symptoms of diabetes. He is underweight, but this has been like this for a few years. There hasn’t been rapid weight loss indicating an urgent need for insulin and his urinary ketones are negative. Other causes of unintentional weight loss such as cancer have also been excluded.So, we are just focusing on the diabetes. His HbA1c is high and has not improved with diet and lifestyle advice, so we should do something. However, given his age, we are not going to manage him too aggressively because, at 85, we are probably more concerned about harmful hypoglycaemia. But he does need treatment and certain diabetic agents could also help his co-morbidities. So, next, we must look at his medical history. He has both CKD and heart failure and we know that SGLT2 inhibitors can be beneficial for both these conditions.However, because of the benefits of metformin, NICE says that first, we should consider starting metformin alone to assess tolerability and once this has been confirmed, we could add an SGLT2 inhibitor.Arguments against using metformin at all in this patient are that his eGFR is fairly low and at 32 he is quite close to CKD stage 4.Also, because he is underweight with possible low muscle mass, we need to remember how the estimated GFR is calculated and consider that, as a result of the low muscle mass, his eGFR may be overestimated and that his actual GFR could be below 30. We know that we can use metformin quite normally if the eGFR is above 45, we need to review the dose and prescribe it cautiously if the eGFR is between 30 and 45 and then stop it completely when the eGFR falls below 30.The manufacturer of metformin also advises caution in chronic stable heart failure with the...
