- A: Abx (metro, sulfas), N: NSAIDs (meloxicam), H: HIV drugs (abacavir), A: allopurinol, T: tetracyclines
1

A
- p: phenothalien, m: metronidazole, s: sulfas, b: barbiturates, t: tetracyclines, n: NSAIDs, s: salycilates, f: yellow food coloring
- fixed drug rxn
- typically single bulluos lesion
2

A
EBV: aminopenicillins
HIV: sulfa drugs (Sulfa Sex)
3
Q

A
HLA B1501: SJS/TEN in response to anticonvulsants (carbamazepine specifically)
4
Q
SATAN will give you SJS
A
- S: sulfa
- A: allopurinol
- T: tetracycline
- A: anticonvulsants
- N: NSAIDs
5
Q
HLA B1501/B1502
A
- 1501: SJS susceptibility with Han Chinese and anticonvulsants
- 1502: SJS susceptibility with white Europeans and allopurinol
~ 1301: in Europeans too
6
Q
HLA B5701
A
Abacavir SJS susceptibility
7
Q
Mediators of SJS/TEN (4)
A
- granulysin, granzyme B, perforin
- soluble fas ligand liberated by mellatoproteases
- granulysin associated with significant apos of keratinocytes
8
Q
Prohapten vs. pharmacological
A
- pro hapten response: drugs digested to substrates which triggers covalent formation of immune molecule
- pharmacological response: non-covalent binding of drugs at MHC I triggering apoptotic response
9
Q
Prognosis/diagnosis potential
A
High serum granulysin and high mobility protein B1
10
Q
Admission to burn unit in relation to toxic epidermolytic necrolysis
A
~ 50% lower with delay
11
Q

A
Seperation of dermis from basal layer upon lateral pressure
12
Q
Asboe-Hansen sign
A
- lateral expansion of bulla upon pressure
