Akshay B. Jain, MD: I’m Dr. Akshay Jain, an endocrinologist from Vancouver, and I’m joined by Dr. James Kim, a primary care physician from Calgary, Canada.
Both Dr. Kim and I attended ADA 2024. We went over all our learnings and decided that there was a whole heap of clinical pearls that we learned from the conference. We thought it would be awesome if we could share our learnings with all of you, both from a primary care lens and from an endocrinology perspective.
One study Dr. Kim and I learned about, and we think has some definite nuances in management of people living with diabetes, regards inhaled insulin. When we have patients in our clinic who have perhaps failed multiple oral agents or have very high blood sugars, we obviously want to consider starting them on insulin for type 2 diabetes.
Sometimes there is a significant barrier, which is related to the needles. There’s an actual term for this: trypanophobia — a fear of needles.
Enter now inhaled insulin. We saw studies at the ADA 2024 conference that looked at a new inhaled insulin called Afrezza. Afrezza essentially is a short-acting insulin, so it’s kind of like a prandial insulin derivative, where it can be inhaled by an individual and it will work for mealtime control of blood sugars.
Dr. Kim, in your practice, how often do you see people not wanting to take shots, and has this been a big barrier for you in starting insulin?
James W. Kim, MBBCh, PgDip, MScCH: Thank you for having me. To answer your question, absolutely I encounter this on a weekly basis — and I’m not even an endocrinologist. I just have an interest in diabetes. There are a number of patients that I think will benefit massively with insulin but they’re needle-phobic. You taught me that word, but I can never pronounce it, so my apologies for not remembering that phobia. I’m just going to call it needle phobia because I’m a simple-minded person.
The needle phobia is massive. I think there’s a definite fear of the needle, but there’s also a fear of failure. As soon as an injection is mentioned, many patients feel they failed miserably. There’s an emotional roller coaster that happens.
I’m sure, Dr. Jain, you have seen many patients, especially from Asia, who would say: “Oh, my auntie got on insulin and 3 months later, she got a kidney transplant.” “My uncle started on insulin and he unfortunately passed away a couple of months later.” Unfortunately, they’re blaming many of those things on insulin.
I also have a number of patients who said they were on insulin before many years ago, and they experienced some severe hypoglycemic events, and they don’t want to get on the insulin ever again. This is unfortunate because you know that if those patients, those aunties and uncles, were on insulin long before, maybe we could have saved their legs and kidneys, and potentially death.
Now we have advanced so much with insulin that hypoglycemia does occur, but much less than before. We still have many barriers when it comes to insulin initiations. Therefore, having this idea of inhaled insulin is fantastic, and I think we can get many more patients on insulin — the medication they actually need.
Dr. Jain: Absolutely. From the studies on inhaled insulin at ADA 2024, the key thing I found very interesting, regarding the pharmacokinetics of the insulin, was that it’s working very quickly. It starts working within minutes of administering it.
Additionally, it lasts in the body only for a shorter duration of time, compared with other injectable short-acting insulins, so it lasts in the body. The active insulin time is roughly about 2 hours or so, based on the studies, which in my mind opens up a whole world of possibilities because it means that people can take another correctional insulin if the blood sugars are still high after taking their first inhaled dose. You can take another dose subsequently without worrying about stacking of insulin.
Many of us are familiar with this term, which is if you take two shots of short-acting insulin too close to each other, the insulin doses might add up and there can be a big drop in the blood sugars; it’s called stacking of insulin. This can be potentially avoided.
Similarly, if you take your dinnertime inhaled insulin and the sugars are still high around bedtime, you could take a smaller dose of the inhaled insulin and not worry about middle-of-the-night hypoglycemia because the effect of the insulin would be only for a little while.
That’s one key learning that I found very helpful. The other important thing that I found was that this is not for everyone, so there are some restrictions. Essentially, the contraindication is that people who have asthma or COPD cannot be prescribed an inhaled insulin.
What are your thoughts, Dr. Kim, based on this for your practice in primary care?
Dr. Kim: It is very fascinating, for sure. I cannot wait to get hold of this insulin. I can already think of some patients who may benefit. You’ve mentioned the asthma and COPD patients, and that makes more sense because there is an actual airway problem.
I also wonder what will happen to patients who have restrictive airway disease, where asthma and COPD fall under obstructive airway disease. What if they have obesity, where it’s really pressing into the diaphragm, and where they may not be able to take the deep breath in? How will they react?
What about someone who’s got a cold, someone who has postnasal drip, or someone who tends to cough frequently? What about egg allergies? There are many question marks around this insulin before initiating these medications. There is excitement, but there are also many questions at the same time.
Dr. Jain: I think these are very important, practical considerations that we’ll uncover as we start using more of this in clinical practice. The other important thing to note is that the presenters told us it’s important to monitor pulmonary function tests. It’s important to get a baseline pulmonary function test, and then we have to do another one in 6 months, followed by annually thereafter.
If, at any point of time, the FEV1 drops by 20% or more, then that would be an indication for discontinuation of the inhaled insulin. The pulmonary function test does not need to be one of those fancier ones. The study group would just do office spirometries. I’m wondering, Dr. Kim, in primary care, do you think this could potentially be a rate-limiting factor?
Dr. Kim: In Alberta, where I reside, no. Spirometry is very easily accessible in the province. For example, in Calgary alone, we have a population of about 1.3 million people. We have over 13 or 15 companies that can do this spirometry. We can get these things done literally within a week or 2.
However, I am aware that, in other provinces in Canada, it can definitely be a huge rate-limiting factor. Not everyone has the office-based spirometry, and definitely not within the primary care office. It has to be referred out to these private companies, most likely, and some of the rural areas will have to rely on the provincial hospitals, where the access can be even more challenging.
On the day of the actual spirometry, if the person has a cough or is not feeling well, it’s going to be a problem because you don’t want the spirometry to be infected with a whole bunch of viruses. You’ll have to cancel that and it can be a bit of an issue.
Dr. Jain: Many of our viewers are from the United States and other parts of the world, and spirometry is quite easily accessible in most places. As an endocrinologist, I must confess that it’s been a long time since I’ve even ordered a spirometry or any clinical form of pulmonary function test. Once I start using the inhaled insulin, I’ll need to start brushing up on my pulmonary function test knowledge.
I think these are exciting times. At least we’ve got something to offer to people who would have otherwise not taken any insulin at all. There’s certainly that hope that now there’s a different way to administer this, and hopefully it can only get better from here on.
Dr. Jain is a clinical instructor, Department of Endocrinology, University of British Columbia, Vancouver. Dr. Kim is a clinical assistant professor, Department of Family Medicine, University of Calgary in Alberta. Both disclosed conflicts of interest with numerous pharmaceutical companies.
