Abstract
Lichen sclerosus (LS) progresivna je kožna bolest koju karakterizira kronična upala genitalne ili ekstragenitalne kože, a nesrazmjerno češće pogađa žene. Imunohistokemijski smo analizirali raspodjelu živčanih vlakana, vaniloidnih receptora te biljege stanične proliferacije, apoptoze, mastocita i makrofaga u genitalnim i ekstragenitalnim uzorcima LS-a, kao i u zdravoj koži. Ukupna količina intraepidermalnih živčanih vlakana bila je manja u uzorcima kože bolesnica oboljelih od LS-a u usporedbi sa zdravim kontrolama, a ukupna je količina subepidermalnih živčanih vlakana i vlakana pozitivnih na peptid povezan s genom-kalcitonina (engl. calcitonin gene-related peptide, CGRP) bila viša u uzorcima genitalne kože oboljelih od LS-a u usporedbi s uzorcima bolesnica s ekstragenitalnim LS-om i zdravim kontrolama. Proliferacija stanica te gustoća makrofaga i mastocita bila je povećana u uzorcima LS-a u usporedbi sa zdravim kontrolama. Uzorci genitalnog LS-a imali su veću gustoću makrofaga u usporedbi s ekstragenitalnom varijantom. Raspodjela mastocita značajno se razlikovala između genitalnih i ekstragenitalnih uzoraka LS-a iako nije bilo razlike u ukupnoj gustoći mastocita. Apoptoza epidermalnih stanica bila je najizraženija u uzorcima genitalne kože bolesnica oboljelih od LS-a. Ova bi otkrića mogla objasniti razlike u jačini svrbeža genitalnog i ekstragenitalnog oblika LS-a i pružiti ciljeve za istraživanje novih terapijskih strategija za liječenje LS-a.
Abstract (english)
Lichen sclerosus (LS) is a progressive skin disease that is characterized by chronic inflammation of either genital or extragenital skin, and it disproportionately affects women. We analyzed the distribution of nerve fibers, vanilloid receptors, cell proliferation, mast cells and macrophages in genital and extragenital LS samples, as well as in healthy skin, by using immunohistochemistry. The total amount of intraepidermal nerve fibers was lower in LS samples compared to healthy controls, while the total amount of subepidermal nerve fibers and calcitonin gene-related peptide (CGRP) positive fibers was higher in genital LS samples compared to both extragenital LS and healthy controls. Cell proliferation, macrophage and mast cell density were increased in LS samples compared to healthy controls. Genital LS had a higher macrophage density compared to the extragenital variant. Mast cell distribution significantly differed between genital and extragenital LS samples, even though their total mast cell densities were similar. Epidermal cell apoptosis was the most prominent in genital LS samples. These findings could explain the differences between pruritic symptoms of genital and extragenital LS and provide targets for the research of novel therapeutic strategies for LS management.
