Reactive Arthritis [Triad, Causes, Diagnosis] | Reactive Arthritis in Children

Reactive Arthritis

Millions of people around the world have arthritis, which is inflammation of one or more joints that causes pain, stiffness, & limited mobility. Reactive arthritis is a type of arthritis that happens because of an infection in another part of the body.

But does reactive arthritis cause any major damage? Or, with treatment, does reactive arthritis die (cure)? Dr. Sameep Sohoni, your trusted Orthopedic Doctor in Thane, is here to explain this situation, give advice, & answer all concerns you may have.

Understand Reactive Arthritis

Reactive arthritis is a bacterial-caused inflammatory arthritis that affects the joints, eyes, skin, & urinary tract. It develops when bacteria enter the bloodstream & induce inflammation in various body parts. The disease is nine times more likely to affect men under 40 age due to sexually transmitted infections.

However, both sexes are equally susceptible to being infected by a food-borne infection. Also, do not confuse reactive arthritis with rheumatoid arthritis. Both are different.

Difference Between Reactive Arthritis and Rheumatoid Arthritis:


Reactive Arthritis

Rheumatoid Arthritis


Infection, often bacterial Autoimmune


After an infection Gradual, no specific trigger

Triad of Symptoms

Arthritis, urethritis, & conjunctivitis (inflammation of the eyes)

Not associated with a specific triad

Age of Onset

Common in young adults

Can occur at any age


Generally short-term

Chronic, lifelong condition

Joint Involvement Affects lower extremities

Can affect any joint


Causes of Reactive Arthritis

Reactive arthritis is primarily caused by bacterial infections (bacteria such as Chlamydia trachomatis, Salmonella, Shigella, Yersinia, & Campylobacter) in the gastrointestinal or genitourinary tract.

A large percentage of reactive arthritis cases are caused by urinary tract infections (UTIs), which are frequently called “reactive arthritis UTIs.”

In rare cases, respiratory infection-causing Chlamydia pneumonia can cause reactive arthritis. Typically, the bacteria enter the body via the vagina or urethra during sexual contact & travel to the bladder.

Reactive Arthritis in Children: Reactive arthritis, a common condition in adults, can also affect children, with symptoms & treatment like adults.

What tests are necessary for reactive arthritis diagnosis?

Reactive arthritis diagnosis is challenging due to the lack of specific laboratory tests but can be determined through symptoms, medical history, imaging, & laboratory tests (like inflammation levels, antibodies, infection, HLA B27 gene, joint fluid, & calcium deposits).

Does reactive arthritis go away?

This arthritis is a temporary condition with no cure, but treatment can alleviate symptoms. Reactive arthritis patients typically recover & resume normal activities a few months after therapy. Symptoms can last up to a year, but are usually moderate & do not interfere with daily life.

However, some may have long-lasting arthritis, with 15-50% developing symptoms again due to reinfection. Chronic, severe arthritis is difficult to treat & can harm joints, with back & joint pain being common recurrences.
