Currently, other types of JIA include:
Systemic, which affects the entire body, including the joints, the skin, and internal organs, according to the Arthritis FoundationJuvenile enthesitis-related arthritis (ERA), which affects the tendons and ligaments attached to the bone, per AboutKidsHealthPsoriatic arthritis, which affects the joints and features a rash on parts of the skin, according to the Arthritis FoundationUndifferentiated, which isn’t clearly linked to one type but has some form of joint swelling and/or pain
Some believe JIA happens as a combination of genetics and some environmental triggers, says Dr. Mehta, “but we don’t know what they are. There are some genes that are identified as having a potential role, but not everyone with those genes gets arthritis, and not all with arthritis have those genes.”
Prognosis of Juvenile Idiopathic Arthritis
With the availability of JIA medication known as biologics, the prognosis for people living with the condition is excellent, says Sura. With the right treatment, people with JIA can expect to have a full quality of life and maintain a full range of joint motion. Before these drugs became available in the early 2000s, people with JIA could experience permanent disability and/or needed joint replacement surgery. Medication to treat JIA can have side effects, so ongoing bloodwork may be needed to ensure, for example, that liver function remains healthy. Most drugs to treat JIA are immunosuppressive, says Sura, so infection risk can be higher than someone not taking these drugs. “I haven’t seen any serious infections among my patients, but they may have a cold that lasts one day longer,” she says. “And with the pandemic and the registry of JIA patients being followed, they don’t seem to have worse rates of COVID or more severe cases of it.” It depends on the type and age of person when diagnosed with JIA, but “in general, about one-third of all kids outgrow it, one-third go into remission for a few years, and one-third have the more chronic form where they flare and still have juvenile arthritis into adulthood,” says Sura.
Some patients with certain forms of JIA may also benefit from a short course of injected corticosteroid drugs. But if these treatments don’t stop joint pain or swelling or joint function does not improve, or if you have a form of JIA that is best treated with stronger medication, the next step is to choose a disease-modifying antirheumatic drug, known as a DMARD. Conventional DMARDs work to suppress the overall immune system, while biologic DMARDs target specific parts of the immune process. Either way, DMARDs can help slow or stop JIA’s joint inflammation and potential joint damage. DMARDs such as methotrexate can cause some nausea or fatigue, and depending on the medication used, patients are prescribed a daily multivitamin and have their blood counts and liver monitored to watch out for side effects. Mehta says most of his patients do well on methotrexate. The growth of DMARDs, particularly biologics, has helped change treatment guidelines for those with JIA. Previously, some people with JIA began taking high doses of steroids at an early age. This led to weakened bones, osteoporosis, and suppressed growth. Starting JIA treatment with biologic DMARDs helps avoid such complications.
Alternative and Complementary Therapies
In early 2022, however, the American College of Rheumatology published guidelines for nondrug treatments for all people living with JIA. These cover physical and occupational therapy as needed, eating a well-balanced and healthy diet as it relates to one’s age, and lab tests both before starting and during treatment with new JIA medication to determine if the drugs are effective. The ACR guidance also urges people with JIA and the people they live with to stay up-to-date on all recommended vaccinations, including annual flu shots and ongoing COVID-19 shots as directed by public health experts. “What I tell families is that they are welcome to try diet interventions, but there are no randomized control studies for juvenile idiopathic arthritis,” says Mehta. “If something works, I’m super happy for them, but it has to be a complement to the standard-of-care medicines.” In other words, such therapies help when they supplement — but never replace — drug treatment. Always speak with your child’s physician about what methods you may incorporate and in what capacity.
A leg length discrepancy, based on joint issues in the knee. This can be treated with a heel lift in the shoe, notes Sura.Muscle atrophy around the knee or other joints. Physical therapy can help build those muscles back up, per Sura and Mehta.Eye inflammation, known as uveitis, or other eye problems such as glaucoma or cataractsWhole-body inflammation. With systemic JIA, a person can develop macrophage activation syndrome, which can trigger serious problems such as a low blood count, organ failure, and death, if not properly treated ahead of time, notes the Arthritis Foundation.Osteoporosis and/or growth problems, according to AboutKidsHealth
Uveitis, or inflammation of the eye. As it may develop without pain and can threaten vision, Sura recommends that all people with JIA see an ophthalmologist to have ongoing dilated eye exams, where the back of the eye can be closely observed with a special machine known as a slit lamp.Psoriasis. This skin condition can coexist with juvenile arthritis and is known as psoriatic juvenile idiopathic arthritis, or psoriasis-related JIA, according to the Genetic and Rare Diseases Information Center.Inflammatory bowel disease (IBS), which includes gastrointestinal problems such as Crohn’s disease and ulcerative colitis. Per the Arthritis Foundation, it is most common in the form of JIA known as juvenile enthesitis-related arthritis.
This website offers good information about juvenile idiopathic arthritis and how parents can talk to their children about it. The Arthritis Foundation also offers information about attending school and college with JIA and hosts summer camps and support groups around the United States and virtually where kids with juvenile arthritis can meet and interact with peers. They also feature a one-on-one helpline (online or phone) staffed by a licensed, clinical social worker who can offer support. Taking Charge: Managing JIA Online Aimed at teens who need to take more responsibility for their juvenile idiopathic arthritis as they grow up, this site — part of AboutKidsHealth and backed with medical guidance by Toronto’s The Hospital for Sick Children — gives a full look at what JIA is, what is needed to stay healthy while living with it, traditional and complementary forms of treatment, and other information for teens to take ownership of their condition as they head into adulthood. American College of Rheumatology While this a physician professional organization, it offers one-page information sheets about different arthritis medication and conditions that may be helpful for families of people with JIA. Your Pediatric Rheumatologist Speak with your child’s physician about what resources they’d recommend. “I think all of us really love what we do when we partner with families on this journey,” says Mehta. For his patients and their families, he says, “I’m with you and I will do my best to figure out what to do to get you answers.”
