Systemic mycophenolate mofetil avoids immune reactions in penetrating high-risk keratoplasty: preliminary results of an ongoing prospectively randomized multicentre study.

Recently, in a monocentre study mycophenolate mofetil (MMF) was demonstrated to be efficacious and safe in penetrating high-risk keratoplasty. Here, preliminary results of a randomized multicentre trial are presented. To date, 86 of 140 scheduled patients undergoing high-risk penetrating keratoplasty have already been randomized into the two study groups: 48 into the MMF group and 38 into the control group.

Topical FK506 as immunoprophylaxis after allogeneic penetrating normal-risk keratoplasty: a randomized clinical pilot study.

The purpose of this study was to evaluate for the first time the efficacy and safety of topical FK506 in patients undergoing penetrating normal-risk keratoplasty in a prospectively randomized clinical trial. Twenty patients were treated with FK506 0.06% three times per day for 6 months postoperatively.

HLA class I and II matching improves prognosis in penetrating normal-risk keratoplasty.

Background: HLA matching in penetrating keratoplasty is still neglected in most eye clinics. This is due to contradictory results of studies performed in the past. Different surgical techniques in multicenter studies, missing risk differentiation in high-risk situations and faulty HLA typing can be identified as the main reasons for these contradictory results.

Soluble Fas ligand and transforming growth factor beta2 in the aqueous humor of patients with endothelial immune reactions after penetrating keratoplasty.

Background: Excellent long-term prognosis of penetrating corneal grafts has been explained by the immunological privilege of the cornea and the anterior chamber. In animal models the secretion of transforming growth factor beta(2) (TGF-beta(2)) into the anterior chamber and the expression of the Fas ligand on corneal endothelial cells were identified as important for the integrity of the immunological privilege.

Objective: To determine the TGF-beta(2) and soluble Fas ligand (sFasL) levels in the aqueous humor of patients after penetrating keratoplasty (PK) who have and who do not have immune reactions.

[Topical Fk506 in inflammatory corneal and conjunctival diseases. A pilot study].

Background: Topical corticosteroids are the only effective measure in serious inflammatory corneal and conjunctival diseases. Although results obtained with topical cyclosporin A are encuraging it is not effective in all patients. The mode of action of Fk506 is similar to that of cyclosporin A, i.
