Neuropeptide and neuronal marker immunoreactivity was studied in skin biopsies from lesional and marginal areas in 12 patients with vitiligo, and in seven normal controls. The vitiligo was active in seven, static in two, and of unknown activity in three. Antibodies against general neuronal marker PGP 9.5 (PGP 9.5), substance P (SP), calcitonin gene-related peptide (CGRP), vasoactive intestinal polypeptide (VIP), and neuropeptide Y (NPY), were used. The epidermis, dermo-epidermal junction, papillary and reticular dermis, and appendages, were assessed semiquantitatively for reactivity with each antibody. Staining with PGP 9.5 in the upper dermis was assessed quantitatively by image analysis. An increase in reactivity against NPY antibody was seen in five of 10 cases (three with active vitiligo) in the marginal areas, and in three of 12 subjects (all with active vitiligo) in the lesional vitiligo areas. VIP antibody reactivity showed a minimal increase in the marginal and lesional vitiligo areas (in two cases each, both of whom had active vitiligo), SP and CGRP reactivities did not differ from normal. PGP 9.5 staining was minimally increased at the dermo-epidermal junction and lower Malpighian layer in biopsies from marginal areas in three of 10 subjects (all with active vitiligo). Quantitative analysis of PGP 9.5 reactivity in the upper dermis showed no difference between vitiligo and normal biopsies. These findings support the concept of neuronal or neuropeptide involvement in vitiligo, and in particular suggest that NPY may have a role in the pathogenesis of the disease.
