Dr Anne-Catherine Raby is a researcher at the School of Medicine, looking for the link between chronic kidney disease and cardiovascular disease with a focus on inflammation. Her work is far-reaching, all-consuming, and imperative in understanding the disease responsible for more deaths globally than any other cause. <\/em><\/strong> <\/p>\n\n\n\n

Sometimes, I want to say this research path chose me.  <\/p>\n\n\n\n

I\u2019ve been working on a particular family of receptors involved in inflammation since my master\u2019s thesis, and inflammation plays such a significant role in kidney disease and cardiovascular disease (CVD), that it was a natural progression.  <\/p>\n\n\n\n

Research in this area is vital because CVD is the number one cause of death globally, with roughly 80 million people dying of a CVD-related condition every year. It is an umbrella term that covers conditions of the heart, the vessels, and the circulation.  <\/p>\n\n\n\n

Unfortunately, it will affect all of us, either directly or through a loved one.  <\/p>\n\n\n\n

But there are good indications that aspects of CVD are changeable. Three quarters of CVD deaths occur in low to middle income countries, suggesting that environment and healthcare options can make a difference. Early management and detection contribute to better outcomes and so we must keep looking for answers, for anything that can make a difference.  <\/p>\n\n\n\n

CVD, inflammation and kidney disease: finding the connection<\/strong> <\/p>\n\n\n\n

It is well accepted in the research community that there is a strong link between some types of CVD and inflammation, but it is not well explained. We can detect inflammatory markers in the blood that either correlate with an underlying CVD condition or correlate with the prognosis.  <\/p>\n\n\n\n

It is a case of the chicken or the egg; we don\u2019t know if inflammation is the cause of CVD conditions, or if it\u2019s the consequence, or if it\u2019s both! But it means that, potentially, inflammation is a very good target for treatment.  <\/p>\n\n\n\n

As well as a connection with inflammation, there is a strong link between the heart and the kidneys. This is known as cardiorenal syndrome.   <\/p>\n\n\n\n

If you smoke or are obese, this can increase your risk of both kidney disease and CVD, and it\u2019s not surprising to find the two diseases in the same people. If your blood pressure is too high that can damage the kidneys. If the kidneys fail, they won\u2019t remove water from your system and your blood pressure increases, which in turn is a problem for the heart. And when you add inflammation into the mix, it can induce problems for both.  <\/p>\n\n\n\n

Why our research has the potential to be game changing<\/strong> <\/p>\n\n\n\n

Our work is heavily based in the laboratory. We do experiments with test tubes, for example using cells from patients and also conduct in vivo experiments. We look at blood from different patients and compare them for levels of particular mediators of inflammation. We have so far found four mediators that are present at higher levels in patients with chronic kidney disease than those of healthy individuals. We have exposed healthy blood cells to these mediators to see if it would induce the healthy samples to behave in the same way. So far, we have found that two of them can indeed make cells behave in a way that promotes the narrowing of the arteries.  <\/p>\n\n\n\n

Some aspects of CVD and kidney disease we can change, and some we cannot. We need to know which things to target and what will improve outcomes. Our hypothesis is that inflammation coming from the kidneys in those with kidney disease worsens CVD development. If we can prove this, we then need to figure out if blocking inflammation is enough to reduce issues. The results could then be turned into something that can be administered either as a prevention, or to block the formation of CVD once it has already begun. The implications of this are fantastic and game changing.  <\/p>\n\n\n\n

There is the possibility that if this applies to one condition, it could be applied to others that work in similar ways. Diseases tend to cluster together in the same individuals, known as \u2018multimorbidity\u2019. If this hypothesis is correct, the aim would be to expand this into the context of other morbidities associated with CVD or kidney disease such as diabetes, dementia and arthritis.  <\/p>\n\n\n\n

The best part of my job is when my experiments generate many pieces of information that I can\u2019t make sense of and I\u2019m trying to figure it out \u2013 like a puzzle. Gradually, you start seeing a picture and it starts to make sense. You don\u2019t get a lot of \u2018eureka\u2019 moments but sometimes you get results that you know will be game changers. Putting the pieces together is definitely the best part of my job.  <\/p>\n\n\n\n

Vital f<\/strong>unding and the generosity of British people<\/strong> <\/p>\n\n\n\n

This research would not be possible without funding \u2013 it makes all the difference. I received my lectureship through Wales Heart Research Institute, and this has allowed me to do this important work. We can spend a year looking for funding and, realistically, this takes your focus away from the research. It can be very disruptive and discourages lots of talented early-career researchers. The implications of receiving funding is that I can continue with my research and transition to a long-term contract and can focus completely on the research. I have two PhD students and I can supervise them without thinking about having to reapply for money in six months. It takes the pressure off and puts me in the best possible position to start building on the research, which can then help me leverage more funding in the future.  <\/p>\n\n\n\n

Donating money is a very personal thing and funding needs to go everywhere, but for those who support research, please be assured that your support is invaluable. I\u2019m always impressed by the generosity of British people. I\u2019ve worked in several countries, but I\u2019ve never seen charities receive such welcome and funding on this scale. British people are very generous!  <\/p>\n\n\n\n
