Ch. 22 - Uveitis in JIA Flashcards
Persistent uveitis with relapses in <3 months after discontinuing treatment
Chronic anterior uveitis
Repeated episodes of uveitis separated by periods of inactivity without treatment for >3 months in duration
Recurrent uveitis
Sudden onset and limited duration uveitis
Acute uveitis
Duration of persistent uveitis
> 3 months
Duration of limited uveitis
3 months or less
Characteristics of uveitis that commonly accompany JIA: Course, location, symptom, onset
Chronic, anterior, asymptomatic, nongranulomatous inflammation, insidious
Characteristics of uveitis that affects HLA-B27 associated diseases like ERA: Course, location, symptom
Acute, anterior, symptomatic
T/F: The choroid (posterior uveal tract) is commonly affected in rheumatic disease of childhood
F
Uveitis in these chronic arthritides are insidious, chronic, and frequently recurrent
Oligoarthritis, polyarthritis, or psoriatic JIA
T/F: Chronic arthritis appears to be particularly uncommon in Asian populations
T
Chronic uveitis is most frequent in what JIA subtypes
Oligoarthritis > RF - polyarthritis > PsA
Chronic uveitis is more common in which gender
F
Mean age of onset of chronic uveitis
4y/o
MC antibody associated with chronic uveitis
ANA
Age-associated risk of uveitis has been seen only in girls. What age group is particularly at risk?
Younger than 7y/o at disease onset
Components of the immune system that play vital roles in the development of uveitis in JIA
T lymphocytes and their products
Innate immune system
Probably B lymphocytes as well
Present in ocular fluids and tissues of adults with AS, the higher levels of which are associated with more severe uveitis
IL-1b, IL-2, IL-6, IFN-y, TNF-a
Levels of this molecule is specially elevated in the aqueous of patients with AS-associated uveitis
TNF-a
Serum levels of these molecules are higher when uveitis is active in adults with anterior, posterior, and panuveitis
IL-6 and 8
Influences the maturation of Th17 CD4+ T cells, which participate in autoimmune disease
IL-6
HLA alleles most strongly and consistently associated with chronic anterior uveitis in JIA
Genes in the class II region
HLA allele associated with acute anterior uveitis
Class I gene HLA-B27
T/F: Up to half of children with chronic uveitis have symptoms attributable to the uveitis
T
Symptoms of anterior uveitis
Redness, pain, headache, photophobia, change in vision
T/F: Uveitis can be detected in patients before onset of arthritis
T, in <10%
T/F: Insidious onset chronic uveitis is commonly bilateral
T, in 70-80%
T/F: Unilateral uveitis may persist for many years in some children before the other eye is involved
T
T/F: Slit-lamp biomicroscopy should be performed on all children with JIA at the time of diagnosis for early detection of chronic uveitis
T
MC symptoms of chronic uveitis
Change in vision and ocular pain and/or redness
Less common symptoms of chronic uveitis
Photophobia and headache
AAP: Frequency of screening of children at high risk for uveitis
Every 3 months
AAP: Frequency of screening of children at moderate risk for uveitis
Every 4-6 months
AAP: Frequency of screening of children at low risk for uveitis
Every 12 months
AAP: JIA group/s at low risk for uveitis
sJIA, all <7 years at onset 7 years after onset, all >7 years at onset 4 years after onset
AAP: JIA group/s at moderate risk for uveitis
All children >7years at onset except SJIA
Poly/Oligo ANA (-) <7years at onset
All high risk patients 4 years after onset of arthritis
AAP: JIA group/s at high risk for uveitis
Poly/Oligo ANA (+) <7years at onset
Children affected by JIA who should have yearly ophthalmologic examination indefinitely
All JIA patients with oligo, poly, and systemic disease
ILAR: Chronic juvenile arthritides at low risk for uveitis
ERA, RF (+) polyarthritis, systemic arthritis
T/F: Children with psoriatic arthritis are also at considerable risk for development of uveitis and should be followed at the same frequencies as children with oligo- or polyarticular JIA
T
T/F: Any child who has had uveitis should be considered to be at high risk, even if it has remitted, and continued surveillance is essential
T
Diagnostic signs of anterior uveitis on slit-lamp exam
Inflammatory cells
Increased protein concentration (“flare”) in the aqueous humor of the anterior chamber
Refers to the deposition of inflammatory cells on the inner surface of the cornea
Keratic precipitates
