Traitement d'une localisation oculaire de pemphigoïde cicatricielle par tacrolimus topique

Tacrolimus exhibits extremely good penetration of the conjunctiva. Following administration at a concentration of 0.06% 3 times daily in 15 patients with inflammatory disease of the conjunctiva or the cornea, improvement was seen in 10 of these patients at 26 weeks. Tacrolimus appears to act through immunomodulatory and anti-inflammatory mechanisms. It induces local inhibition of T lymphocyte activation and reduces production of pro-inflammatory lymphokines. Oral tacrolimus cannot be used to control cicatricial pemphigoid refractory to standard immunomodulators. However, 3 three other cases involving topical treatment of cicatricial pemphigoid showed marked efficacy of treatment given for 2 to 6 months, with complete tolerability. Thus, topical tacrolimus appears to constitute an interesting alternative treatment in cicatricial pemphigoid.
