Researchers from Sandwell and West Birmingham hospitals NHS trust and the University of Birmingham examined IBD cases from the beginning of the century to collect accurate data on ulcerative colitis (UC) and Crohn's Disease (CD) prevalence in the UK.
Data collected from the Health Improvement Network (THIN), a nationally representative UK primary care database, demonstrates that IBD prevalence is three times higher than previously reported, with UC and CD prevalence increasing by 55% and 83% respectively, between 2000 and 2017.
The study, presented yesterday (October 23rd) at UEG Week in Barcelona, also showed that IBD prevalence is predicted to rise by almost a quarter from 2017 to 2025.
Researcher Dominic King, from the University of Birmingham, who presented the findings, said: "Our study suggests that IBD prevalence is likely to rise substantially over the next decade.
"As there is currently no known cure for IBD, patients will often need complex and costly treatments throughout their lives. This predicted rise in prevalence may place an even greater strain on already overburdened healthcare systems.
"The burden of IBD is compounded further by an association with colorectal cancer. Our study found that patients suffering from Crohn's disease had a 23% increased risk of developing CRC compared to matched controls, whilst ulcerative colitis patients had a significantly elevated risk of 43%. The rise in prevalence of IBD could therefore potentially lead to an associated rise in CRC cases."
Salvo Leone, President of the European Federation of Crohn's and Ulcerative Colitis Associations (EFCCA) gave his reaction to the results.
"The results of the study are alarming, particularly if we consider the fact that Crohn's disease and ulcerative colitis are lifelong diseases that can begin at a young age and have a huge impact on a patient's quality of life."
Affecting over 3 million people across Europe, IBD is a group of disorders involving chronic inflammation of the gut.
The severity of the symptoms and the long-lasting nature of the diseases can have an extremely debilitating impact on the lives of sufferers. For example, higher rates of depression and reduced workforce participation in patients with UC and CD has been reported in previous studies, with an estimated 44% of IBD sufferers claiming they had lost or quit their job because of IBD.
"The cost to society, either through direct medical costs or indirect costs such as lost days at work, lost educational opportunities, or caring for an affected family member, are enormous," Leone continued.
"We need to put all our efforts into developing effective treatment and disease management strategies that allow patients and their families to lead happier and healthier lives."
