More Windex: Steroid Inhalers and Bone Health

By /

steroid inhalers and fractures 2

Steroid inhalers are common these days. The idea was supposed to be that by inhaling low doses of steroids, we could avoid the side effects of higher oral and intravenous steroids. Did this turn out to be true? Nope. Let’s dig in.

Steroids are Super Nasty

As I wrote yesterday, steroids are the Windex of medicine. Do you remember the father in My Big Fat Greek Wedding who would spray Windex on everything? Well, that’s how most physicians view steroids. We use them for everything from knee pain to asthma.

The problem? Steroids have been associated with all sorts of nasty side effects. For example, a bone disease where your bones turn to mush (osteonecrosis). This happens in a dose-dependent fashion (6). Meaning the more steroids you get exposed to, the more likely you are to get this awful disease.

Here are some other issues:

  • Elevated blood sugar
  • Increased risk of infection
  • Glaucoma
  • Suppression of adrenal gland hormone production
  • Fluid retention
  • Confusion or delirium
  • High blood pressure
  • Weight gain and cushingoid syndrome (bizarre fatty deposits like a moon face)
  • Osteoporosis

Steroid Inhalers

334 million people worldwide are diagnosed with asthma, a condition characterized by airway constriction that makes it hard to breathe. Steroids can reduce inflammation which can open the airways. Hence, they have become a mainstay of asthma treatment.

When steroid inhalers made their debut a few decades ago, the idea was simple. Reduce the dose of steroids and make it easy for the patient to conveniently inhale every day with a small device that they can carry. This will reduce the need for higher dose steroids that we know can cause severe side effects and patients will be safer. However, research now shows that this was wishful thinking.

New Research

By examining data from anonymized health records, researchers who authored an October 2020 study published in the journal Thorax concluded that patients on steroids for asthma had higher rates of osteoporosis and fractures than those who didn’t use steroids. And the higher the cumulative dose and the longer they were on the medication, the greater the risk.

Individuals who were given 9 or more prescriptions for steroid pills in a year were at the greatest risk of osteoporosis — more than 4 times more likely to develop the degenerative bone disease. They were also at higher risk for fragility fractures, even after accounting for influencing factors like smoking, weight, and alcohol intake. The most surprising thing in the study was that the risk for fractures and osteoporosis was elevated by about 60% for steroid inhalers. That’s not supposed to happen.

What We Know

Several previous studies — including one from September 2010, have linked corticosteroid use and osteonecrosis, a degenerative disease that results from fewer stem cells and the eventual collapse of the bone (2). Even short-term use has been associated with an increased risk of fractures, blood clots and sepsis, according to an April 2017 study in BMJ (3).

But there’s also some potentially promising evidence that vitamin E supplementation may prevent steroid-induced osteonecrosis, according to a February 2010 study (4). And an August 2014 study suggests that curcumin’s anti-inflammatory properties may help alleviate some asthma symptoms when used in conjunction with corticosteroids (5). This could lessen the number of inhaler prescriptions required.

The upshot? Patients who use steroid inhalers are at risk for bone diseases. That’s a fact that would likely surprise most physicians who write these scripts. So like everything else in healthcare, buyer beware!
