Study Details

Study Description

Brief Summary

It is planned to explore the efficacy and safety of local 0.05% cyclosporine eye drops in the treatment of chronic graft-versus-host eye disease. Through the comparative study with 0.1% tacrolimus eye drops, to clarify the short-term and long-term efficacy of 0.05% CSA in these patients, and to explore the benefits of long-term maintenance of local cyclosporine to patients.

Detailed Description

Chronic graft-versus-host disease (GVHD) is a common and serious complication after allogeneic hematopoietic stem cell transplantation. Its clinical presentation is similar to that of an autoimmune disease and can affect many organs, including the skin, liver, gastrointestinal tract, lungs and eyes. Ocular GVHD occurs in 30-60% of patients undergoing hematopoietic stem cell transplantation and 60-90% of patients with other systemic GVHD. Chronic ocular GVHD usually occurs 9-24 months after hematopoietic stem cell transplantation and mainly affects the cornea, conjunctiva, lacrimal gland, eyelid and meibomian gland, and leads to inflammation and fibrosis of these tissues. The characteristic manifestations of chronic GVHD include dry keratoconjunctivitis, cicatric conjunctivitis, punctate keratopathy, corneal ulcer and perforation. Severe dry eye is the most common manifestation of ocular GVHD. Patients have burning sensation, foreign body sensation, photophobia, dry eye, itching and other symptoms. This is associated with reduced tear secretion due to damage to the lacrimal gland as well as with goblet cell loss and tear film instability due to meibomian gland dysfunction. Chronic eye GVHD has the potential to cause severe visual impairment and significantly reduce the patient's quality of life. The principle of topical treatment of ocular GVHD is to lubricate the ocular surface, reduce ocular surface inflammation, prevent tear evaporation, and promote epithelial repair. Specific local treatment options include glucocorticoids, immunosuppressants, growth factors and artificial tears. Local glucocorticoids are the first-line treatment at the present stage, but the side effects of hormone therapy are relatively large. Long-term use can lead to damaged epithelial formation, thinning of the cornea, increased intraocular pressure, cataract, infectious keratitis, etc. Therefore, it is necessary to closely monitor the treatment period and minimize the use time. At present, the most commonly used topical immunosuppressants are tacrolimus (FK506) and cyclosporine (CsA). Both belong to calcineurin inhibitors, which can inhibit the activation of calcium-dependent T cells, thus exerting immunosuppressive effect. 0.05% CsA is an eye drop mainly used for the treatment of moderate and severe dry eye, with good therapeutic effect and tolerability [18-23], but slow onset of effect. In the treatment of patients with chronic ocular GVHD, previous studies have shown that cyclosporine eye drops can improve patients' dry eye symptoms, reduce corneal fluorescence staining, and increase tear film rupture time. However, the number of clinical studies on the treatment of chronic ocular GVHD with 0.05% CsA eye drops is limited, with a small number of patients enrolled and relatively short follow-up time. The immunosuppressive effect of tacrolimus is significantly higher than cyclosporine, which is 100 times higher than reported in literature. Therefore, tacrolimus is mainly used for the treatment of rejection after corneal transplantation and immune-related ocular surface diseases. What is the efficacy and tolerability of such a powerful immunosuppressant in treating GVHD? There are few literature reports, but long-term ocular application can reduce local immunity and increase the risk of local infection. At the same time, tacrolimus is very irritating, and some patients cannot tolerate it and choose to stop using the drug. At present, there is still a lack of clinical evidence to compare the efficacy of cyclosporine and tacrolimus eye drops in patients with chronic ocular GVHD. Therefore, by comparing the effectiveness, safety and tolerance of 0.05% CsA eye drops and 0.1% tacrolimus eye drops in the treatment of chronic eye graft-versus host eye disease, this study aims to explore a reasonable treatment plan for chronic eye GVHD and provide theoretical basis for clinical application.
