Medical cannabis treatments for AOSD
Adult-onset Still’s disease (AOSD) is an extremely rare form of inflammatory arthritis. Symptoms include joint pain and stiffness, fever, a rash, and a sore throat. The symptoms vary in severity, and some may not appear at all. Sometimes, symptoms like the fever and rash come and go, making the condition challenging to diagnose.
AOSD only occurs in adults, but is named after Still’s disease, also known as systemic juvenile idiopathic arthritis (JIA), which only occurs in children. Because AOSD has so many of the same symptoms as JIA, it’s thought to be a related condition with similar causes.
Experts consider AOSD an autoimmune condition, meaning it’s triggered by the body’s own immune response. AOSD may gradually ease on its own or develop into a longer-term condition. As well as standard medications, many people seek alternative treatments for adult-onset Still’s disease, to better manage symptoms like pain and anxiety.
Patients may be prescribed medical cannabis for adult-onset Still’s disease treatment, to help ease multiple symptoms and improve quality of life.

A word from our specialist
“Adult-onset Still's disease is a rare type of inflammatory arthritis that can cause symptoms like fever, joint pain and rash. Flare-ups often occur without any warning and can be debilitating.
For many patients, living with this unpredictability can make life much harder to live and enjoy.
Treatment involves controlling the inflammation with immunosuppressive medications, but many symptoms can also be managed with medical cannabis.
While it won’t be suitable for everyone, it may be worth discussing as part of a wider treatment approach.”

Can medical cannabis treatments help the symptoms of adult-onset Still's disease?
Yes, medical cannabis may help control some of the co-occuring symptoms of Adult-onset Still’s disease (AOSD).
Adult-onset Still’s disease (AOSD is a rare form of arthritis associated with pain and inflammation, fever, a sore throat caused by swollen lymph nodes, and a pink rash. The rash can be hard to spot, depending on your skin tone, and both the rash and fever may come and go. Some people find that the fever occurs more in the morning, or is worse at certain times of day.
AOSD is caused by your body’s own immune response. In other words, the body believes that something is attacking it and responds by raising inflammation levels across multiple joints. Because it impacts various areas of the body, AOSD is known as a systemic condition.
Another common symptom of AOSD is severe fatigue, which may not be improved with rest or sleep. Sleep disruptions are also common due to the pain. The ongoing symptoms and unpredictability of the condition can also lead to anxiety and depression.
Who does adult-onset Still's disease affect in the UK?
Adults of any age may develop AOSD, and the exact cause is unknown. Experts state that the condition is most likely to start between the ages of 16 and 35, and is more prevalent in women.
What symptoms does adult-onset Still's disease cause?
As an arthritic condition, pain is often the most challenging symptom associated with AOSD. Treatment plans are usually focused on pain management, which will help the patient sleep better and regulate their mood more effectively.
Here’s a closer look at some of the most common symptoms of AOSD:
|
AOSD symptom |
How symptom presents |
Impact on quality of life |
|
Rash |
Pink spots on the skin that may fade and come back |
Lowered self-esteem; worry and anxiety |
|
Fever |
Feeling hot; sweating profusely; sleeplessness; general feeling of unwellness |
Inability to do daily tasks; reduced levels of personal hygiene, especially where pain makes showering or bathing difficult |
|
Pain |
Arthritic pain can range from a dull, constant ache to intense, burning flares |
Sleep disturbances; anxiety from wondering when the next flare will come; depression caused by the ongoing nature of chronic pain |
|
Fatigue |
Intense tiredness that doesn’t go away after rest or sleep; weakness |
Decreased mobility and ability to work or do daily tasks; low mood leading to depression if not addressed |
The psychological impact of this condition can’t be ignored. Not knowing when a flare-up may occur, or when the condition may ease, can lead to intense anxiety and depression.
What is macrophage activation syndrome, and why does it matter for AOSD patients?
A more dangerous complication of AOSD is macrophage activation syndrome. (MAS). MAS occurs as a secondary condition to some rheumatic and arthritic diseases. It occurs when the immune system goes into overdrive, producing acute levels of inflammation that can cause organ failure. Steroids and biological treatments may be required to slow and stop MAS.
If untreated, MAS has a potential lethality rate of up to 53%.
What treatments are currently available for adult-onset Still's disease?
The primary treatments for AOSD are pain medications, ranging from non-steroidal anti-inflammatory drugs (NSAIDs) to corticosteroids. Other medications work by suppressing the immune system, while some are classed as biological treatments and work by adding antibodies to help regulate the immune system.
Some more detailed information on specific AOSD treatments:
|
AISD treatment option |
How it works |
Potential side effects (varies from person to person) |
|
Canakinumab, sometimes called Ilaris |
Canakinumab is a monoclonal antibody that blocks the action of a protein associated with inflammation. |
Colds and upper respiratory infections; pain; redness |
|
Methotrexate |
This drug works to suppress the immune system, potentially slowing the progress of inflammation and pain. |
Sensitivity to sunlight; nausea and vomiting; loss of appetite; headaches; fatigue; hair loss |
|
Ciclosporin |
Ciclosporin is another type of immune system suppressant that works by decreasing the activity of lymphocytes. |
High blood pressure; vomiting; kidney problems; fluctuating hair growth; headaches |
|
Intravenous immunoglobulin |
This process takes donated antibodies and uses an IV to introduce them to the patient’s body, in an attempt to regulate the immune system. |
Chills; lethargy; headache; flushes; fatigue |
Can medical cannabis treatment help with my adult-onset Still's disease symptoms?
There are many different conditions medical cannabis can be prescribed for, and depending on your specific situation, AOSD may be one of them. Medical cannabis for adult-onset Still's disease is a potentially therapeutic alternative treatment that could help with symptoms including:
-
Pain and inflammation
-
Anxiety
-
Depression
Regulating your sleep pattern can be a key factor in regaining a feeling of control over your life, and avoiding associated mental health problems.
THC for adult-onset Still's disease may help reduce the pain associated with arthritic conditions like AOSD. Medical cannabis contains many therapeutic compounds beyond THC, including CBD and terpenes. The application of CBD for adult-onset Still’s disease could help with relaxation and sleep.
Importantly, when a clinician prescribes medical cannabis, you gain the benefit of a balance of these compounds. Releaf clinicians understand different medical cannabis strains and will find the right one for you. They’ll consider indica vs sativa strains, for example, or whether a strain with higher levels of CBD may be beneficial.
How does the endocannabinoid system relate to adult-onset Still's disease?
The human endocannabinoid system is a network of receptors in the body that impacts different organs and systems, including the immune system. When all your systems are working in harmony, this promotes a state of being called homeostasis, which promotes wellness.
Your body produces its own cannabinoids, which bind to the receptors in the endocannabinoid system. However, the system can still be unbalanced and not able to regulate your internal environment effectively. Medical cannabis may offer therapeutic effects via plant-based cannabinoids and other compounds like terpenes, which help re-regulate the endocannabinoid system.
With a prescription of medical cannabis AOSD pain and inflammation may be reduced, and some patients experience improved sleep and better mood management.
What does the research say about cannabis and adult-onset Still's disease?
Research specifically into the impact of medical cannabis for adult-onset Still’s disease treatment is currently lacking. However, there have been studies into how medical cannabis impacts patients with other arthritic conditions.
Data published in the journal Cureus showed an assessment of 290 patients diagnosed with different types of arthritis. Patients reported a significant drop in pain levels after taking cannabinoids. Specifically, on the pain scale from 1-10, the average pain level fell from 6.16 to 3.89.
When it comes to medical cannabis, systemic inflammatory arthritis conditions like AOSD could be easier to live with when taking a medically-advised prescription. Patient stories offer anecdotal evidence that supports this, including this statement from one patient who was struggling with both pain and sleeplessness:
“Before medical cannabis, I couldn't sit or stand still, even for short periods. I’d be up and down, changing positions and always moving around. Now, I’m able to sit still for longer periods, which is quite impressive. My pain has eased a lot, compared to what it was, and there have been no negative side effects—nothing at all.”
