Juvenile Seronegative Polyarthritis

Juvenile Polyarthritis (seronegative)


Presentation

  • Oligoarticular or polyarticular arthritis of a duration of six weeks or longer must be present to diagnose JIA. Patients may present with an acute onset of symptoms or a more gradual onset.[radiopaedia.org]
  • Acute polyarthritis has a very wide differential diagnosis, presenting significant diagnostic difficulties.[patient.info]
  • It usually presents in those under 6 years old and is more common in females. It typically presents with one or two swollen joints causing stiffness and reduced movement but often not much pain. The child usually feels well.[patient.info]

Joint Swelling
  • It causes joint swelling, pain, stiffness, and loss of motion. It can affect any joint, but is more common in the knees, hands, and feet. In some cases it can affect internal organs as well.[icdlist.com]

Treatment

  • Still osteopathic methods, treatment of acutely ill hospital patients, somatic dysfunction, clinical research and trials, outcomes research, and biobehavioral interactions with disease and health.[books.google.com]
  • Case-specific questions were asked regarding (1) initial treatment of oligoarthritis, (2) treatment of refractory oligoarthritis, (3) treatment of complications (uveitis refractory to topical steroids). III.[ped-rheum.biomedcentral.com]
  • Management and treatment Treatment is best managed by a paediatric rheumatologist in collaboration with physiotherapists and ophthalmologists. Initial treatment revolves around administration of NSAIDS.[orpha.net]
  • Just as treatment has changed through the years, so has the thinking about RA in some cases.[arthritis.org]
  • Read more: Antibiotics may play a role in juvenile arthritis » Could research lead to treatments? But it is possible that these findings may eventually provide better, more targeted novel treatment therapies for JA and RA patients alike.[healthline.com]

  • Etiology Oligoarticular juvenile arthritis is an autoimmune disorder, but the exact disease mechanism and triggering factors are unknown. However, the disease has been associated with HLA class II antigens, HLA DR3 and DRB1*08.[orpha.net]
  • To more accurately assess the incidence of childhood arthritis and to better understand its etiology, it is necessary to both more rigorously and more inclusively define the diseases which cause arthritis in children.[eldersarthritis.com]

Epidemiology

  • Epidemiology References: [1] Epidemiological data refers to the US, unless otherwise specified.[amboss.com]
  • Summary Epidemiology Its prevalence is estimated at 1-10 in 6,500 children, with an annual incidence of 1-20 in 1,000,000 children.[orpha.net]
  • Epidemiology The overall prevalence is estimated to be 1-2 per 1,000 children, with an incidence of 1 per 10,000. [ 3 ] It is more common in females, although there are differences depending on the subset.[patient.info]

  • Using condoms is important to prevent sexually transmitted infections (STIs) even when using hormonal contraception.[arthritisresearchuk.org]
  • Their hope is that a better understanding of the differences between the diseases we call RA may provide insights that could eventually lead to new ways to treat and, perhaps in some cases, even prevent it.[arthritis.org]
