Antibodies To Things Flashcards
Ds-DNA (double stranded DNA)
MOST highly specific for SLE
Lupus nephritis
What Ab can you order with a high sensitivity for SLE?
Ds-DNA
- a/w high specificity for SLE
- predicts lupus nephritis
- correlates with disease severity
What antibody do you order which is a/w lupus nephritis in SLE?
Double-stranded DNA or Anti-Sm
- also anti-Smith does as well
- ds-DNA has a high specificity for SLE, predicts disease severity, correlates with early/severe disease
Anti-Sm
A/w lupus nephritis, highly specific for SLE
*So is anti-dsDNA
Anti-rRNP (U1 RNP)
R-RNP - Highly specific for neuropsychiatric LE *per Jain
U1 RNP - Highly specific for MCTD *per Hocker
What antibody do you test if you are suspicious for neuropsychiatric LE?
Anti-rRNP (U1RNP)
Anti-Ro (SSA)
Anti-La (SSB)
SJOGRENS!(Most strong association)
SCLE
Neonatal lupus/congenital heart block
What antibodies do you order to check for SCLE
Anti Ro(SSA)/La(SSB) *also a/w congenital heart block
Anti-SSA,Anti-SSB is the same Ab as what?
Anti-Ro/Anti-La
*checks for SCLE/neonatal lupus/congenital heart block/ AND Sjogrens
Antibody to check for neonatal lupus?
Anti-Ro/La (same thing as SSA/SSB)
Strongest Ab a.w Sjogrens
Anti-Ro, Anti-La
- MOST SPECIFIC -Anti fodrin
- which are also a/w SCLE/neonatal lupus
What two diseases is anti-Ro/La a/w?
SJOGRENS (strong) (sidenote* anti-fodrin is most specific)
SCLE/neonatal lupus
Anti-U1RNP
MCTD
*also can see in SCLE but mostly MCTD
Anti-histone
Drug induced SLE
Antibody indicating drug induced SLE/SCLE
Anti-his tone
Anti-KU
SLE with polymyositis
Antibody for drug induced polymyositis
Anti-KU
Anti-ssDNA
Increased risk of SLE in DLE
What antibody would you order in a DLE patient to assess their possible risk for SLE?
Anti-ssDNA
