PEOPLE living with type 2 diabetes are at higher risk of liver disease, research has found. Many patients with potentially deadly liver cirrhosis and liver cancer are being diagnosed at late, advanced, stages of the disease, according to a study led by Queen Mary University of London and the University of Glasgow.
The study of 18 million people across Europe suggests those living with type 2 diabetes are at particular risk of this “silent disease” and should be monitored closely to prevent life-threatening disease progression.
Non-alcoholic fatty liver disease (NAFLD) affects up to a quarter of people in the West and is the most common cause of liver disease around the world. It is closely associated with obesity and type 2 diabetes, and GPs are often unaware of the condition and patients often go undiagnosed, Queen Mary University of London said.
For the majority, NAFLD is a benign condition, but one in six people will go on to develop the aggressive form of the disease, called non-alcoholic steatohepatitis (NASH), leading to liver injury, scarring and eventually in some to cirrhosis, liver failure and even liver cancer. By identifying which patients might go on to develop the more aggressive disease, interventions and treatments could be targeted at those in greatest need.
In the largest study of its kind, published in the journal BMC Medicine, the team combined the healthcare records of 18 million European adults from the UK, Netherlands, Italy and Spain. They matched each NAFLD patient to 100 patients who did not have a recorded diagnosis, and looked to see who developed liver cirrhosis and liver cancer over time.
More than 136,000 patients were identified with NAFLD/NASH and were more likely to have type 2 diabetes, hypertension and obesity than matched controls.
The strongest association was in
NAFLD/NASH patients who had a
diagnosis of type 2 diabetes – they were more than twice as likely to develop aggressive liver disease, suggesting diabetes could be a good
predictor of liver disease progression.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
