Tyrosine hydroxylase autoantibodies impair sympathetic innervation leading to keratitis. In this study, the investigators have shown the significant association between severity of keratitis and presence of tyrosine hydroxylase autoantibodies.
Sixteen consecutive cases diagnosed with APS-1associated keratitis were included in this study. Each patient underwent complete ophthalmologic examination. Blood was obtained from each patient for testing the endocrine functions and determination of a panel of autoantibodies to the following: Side-chain cleavage enzyme (SSC), Aromatic L-amino acid decarboxylase (AADC), Tryptophan hydroxylase (TPH),Tyrosine hydroxylase ( TH), 17 α-hydroxylase (17α-OH), Cytochrome P450 1A2 (CYP1A2), 21-hydroxylase (21-OH), Potassium channel regulatory protein (KCNRG), Tyrosine phosphatase-like protein IA-2 (IA-2), Glutamic acid decarboxylase 65 (GAD65), NACT Leucine-Rich-Repeat-Protein 5 (NALP5), and Interleukin (IL) 22.
