What are the symptoms of Still's disease?

Still's disease is actually a type of arthritis, but it is a type of arthritis that is more common in children, especially in children under ten years old. Children with Still's disease generally have obvious physical symptoms, such as fever, rash, arthritis symptoms, etc. Parents should pay more attention to whether their children are feeling unwell.

Still's disease is a seronegative polyarthritis and a form of juvenile rheumatoid arthritis. Still's disease (AOSD) is a relatively rare inflammatory disease that has a group of clinical and laboratory features similar to systemic juvenile arthritis (Still's disease). It is characterized by daily peaks of fever, arthritis, and a rash that typically occurs during the febrile period and disappears each day.

The disease can occur in both men and women, and is more common in children aged 2 to 10 years old.

1. The fever is of the remittent type, generally above 39-40°C, and the temperature fluctuation range can reach 2-3°C per day. The patient's body temperature may be very high, but the symptoms of poisoning are slightly milder and the general condition is good. Fever may recur after 1 to 2 weeks, sometimes presenting as persistent fever, and the fever may last for months to years.

2. Rash Fever and rash often exist at the same time. The rash is polymorphic and variable. It can present in various forms such as macules, papules, urticaria, scarlet fever-like erythema, measles-like erythema, erythema multiforme and erythema nodosum. Varying in size and irregular in distribution. Pigmentation may remain after fading. The rash often recurs.

3. Joint symptoms can affect large and small joints of the limbs, manifesting as pain, mild swelling, and migratory pain. Symptoms worsen during fever and resolve on their own when fever subsides.

4. Other symptoms may include pericarditis, myocarditis, pleurisy, hepatosplenomegaly and jaundice. Superficial lymph nodes are swollen, mostly in the sides of the neck, armpits, and groin, with no significant tenderness.

The diagnosis can usually be made based on typical clinical manifestations and laboratory tests.
