Multicenter clinical trial on the effectiveness and safety of outpatient treatment of acute uncomplicated diverticulitis without antibiotics versus antibiotic treatment. ADIANA Trial.
This important study, called ADIANA, is looking into how best to treat a common bowel condition called diverticulitis when it's not severe. Doctors are comparing two ways to treat it: one group of patients will receive antibiotics, and another group will not. The main goal is to check how well each treatment works and whether people get better quickly, both in the short term (within 48 hours) and after a month. They also want to see if one treatment leads to fewer problems later on, how quickly people can return to their daily lives, and if antibiotic-free treatment is a safe and effective option. This could help doctors decide the best way to care for people with diverticulitis in the future.
At a glance
What is this study about?
You might have heard of a condition called diverticulitis, which is when small pouches in your large bowel (colon) become inflamed or infected, causing pain and other symptoms. This study, known as the ADIANA Trial, is focused on 'uncomplicated' diverticulitis, meaning cases that are not severe and don't immediately require hospitalisation.
Traditionally, antibiotics have often been used to treat diverticulitis. However, there's growing interest in whether some people with less severe forms of the condition might get better without antibiotics. Using fewer antibiotics when they're not absolutely needed can be a good thing, as it helps reduce the risk of antibiotic resistance – where antibiotics stop working effectively – and can also prevent side effects from the medication.
So, this study aims to carefully compare these two approaches: treating diverticulitis with antibiotics versus treating it without. Researchers will be closely watching how well patients recover in both groups, how quickly they feel better, and if they experience any issues or if the condition comes back. The results will help doctors understand if avoiding antibiotics is a safe and effective option for many patients in the future, potentially changing how this common condition is managed in the UK.
Key takeaways
- This study compares treating mild diverticulitis with or without antibiotics.
- It aims to find the safest and most effective treatment option.
- Participants will be closely monitored to see how quickly they recover.
- The study could help reduce unnecessary antibiotic use.
- It’s for adults diagnosed with uncomplicated diverticulitis who can be treated at home.
Who may be eligible?
This study is looking for adults aged 18 and over, of any gender. To be considered, you must have been recently diagnosed with 'acute uncomplicated diverticulitis'. This means you have new symptoms of diverticulitis that are not severe and do not require immediate hospital care because of complications like a serious infection or a burst bowel wall.
Your doctor will need to confirm your diagnosis based on your symptoms and possibly scans. You also need to be well enough to be treated at home rather than needing to stay in hospital. The research team will review your medical history to make sure the study is a safe and suitable option for you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Have you recently been told you have diverticulitis?
- Is your diverticulitis considered 'uncomplicated' (not severe)?
- Are you well enough to be treated at home for your condition?
What does participation involve?
If you decide to take part in this study, you would first have a full check-up by the study team. You would then be randomly assigned to one of two groups: either you receive a standard course of antibiotics, or you receive treatment without antibiotics. The specific antibiotics used would be chosen by your doctor from a list of common ones, such as Ciprofloxacin, Amoxicillin/Clavulanic Acid, or Metronidazole.
Throughout the study, the research team would closely monitor your health and recovery. You would have check-ups to see if your symptoms are improving, how quickly you get back to your normal daily activities, and if you experience any side effects. These check-ups would happen shortly after starting treatment (within 48 hours) and again after about one month. The total length of your participation would involve this initial treatment period and follow-up for at least one month.

Common questions
What is diverticulitis?
It's a common condition where small pouches in your bowel become inflamed or infected, causing tummy pain and other symptoms.
What does 'uncomplicated' mean?
It means your diverticulitis is not severe and doesn't involve serious issues like a burst bowel, so you don't need urgent hospital care.
Who can join this study?
Adults aged 18 or over, of any gender, who have recently been diagnosed with uncomplicated diverticulitis.
Will I definitely get antibiotics?
You will be randomly assigned to either receive antibiotics or not, as doctors are comparing both approaches.
What if my symptoms get worse?
If your condition doesn't improve or worsens, you will receive appropriate medical care, including antibiotics if needed.
