Let me tell you, folks, we’ve got something huge here. We’re talking about Giant Cell Arteritis (GCA), the biggest player in the game when it comes to vasculitis in adults over 50. And guess what? We dove deep into the heart of Waikato, Aotearoa New Zealand, to crack the code on this one. We wanted the real deal on GCA’s incidence and prevalence, and let me tell you, we got it.

From 2014 all the way to 2022, we were on the hunt, checking out every angle – from ultrasound requests to biopsy reports. We didn’t just look back; we looked forward, gathering data like nobody’s business. And the numbers? Incredible. We’re talking 214 patients diagnosed over nine years. And get this – nearly 94% were European. But here’s something: Māori patients, they’re younger when they get hit with GCA.

Now, let’s talk numbers – the mean annual incidence? A solid 14.7 per 100,000 people over 50. And the standardised mortality ratio? 1.18. That’s right, folks, we’re not just throwing numbers around; we’re talking real, solid research here.

This isn’t just any study; it’s the largest study on GCA in Aotearoa New Zealand to date. And what we found? The incidence of GCA, it’s stable, it’s consistent. And here’s the kicker – it’s pretty uncommon in Māori, Pacific Islander, and Asian groups. So, we’re looking at a clear picture here, a comprehensive understanding of GCA in this beautiful part of the world.

So, remember, when it comes to understanding GCA in Aotearoa New Zealand, this study, it’s huge. It’s the best, and it’s giving us insights like never before. Believe me.
