NCT04375852

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • To report the correlation between autoantibodies with the severity keratitis in patients Autoimmune polyglandular syndrome type 1 (APS-1).

    Blood was obtained from each patient for 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), 17α-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.
