Atopic keratoconjunctivitis (AKC) is a rare type of ocular allergy that is often associated with eczema. Over time, the complications from this disease process lead to loss of vision due to continual scarring of the corneal surface. The pathophysiology of AKC has not been fully elucidated, and the triggers are still unknown.
Corticosteroids are very effective in controlling the acute symptoms of AKC. However, two thirds of patients managed with a combination of oral antihistamine, topical mast cell stabilizer, and intermittent topical steroid regimen eventually developed significant keratopathy and vision loss. Additionally, there are many side effects of corticosteroids, including local immunosuppression, cataract formation, and increased risk of glaucoma.
Cyclosporin A is an immunomodulator that specifically inhibits T lymphocytes by blocking the expression of the interleukin-2 receptor. It also blocks the release of inflammatory mediators from mast cells and eosinophils. Cyclosporin has no known side effects except for burning upon instillation, and safe to use over long-term . The investigators have demonstrated that a 0.05% ophthalmic emulsion of cyclosporine has been shown to be effective at improving the ocular signs and symptoms of AKC over short-term. However, the long-term efficacy of cyclosporine A in slowing the natural history of AKC and possible steroid sparing effects have not been assessed. The investigators hypothesize that cyclosporine A can be used as a mainstay treatment of AKC to control signs and symptoms over a long period of time and also prevent the progression of this disease.

The study was a double-blind, parallel study to compare efficacy of 0.1% tacrolimus ophthalmic ointment vs 2% cyclosporine eye drops in children with vernal keratoconjunctivitis. The durat...
The purpose of this project was to analysis the causes, pathogenesis, diagnostic modalities and treatment outcomes of microsporidial keratoconjunctivitis.
This is a randomized, double-masked, vehicle-controlled study of the safety and efficacy of OTX-101 (0.09% cyclosporine nanomicellar solution) in the treatment of keratoconjunctivitis sicc...
We found upregulation of 47 immunoglobulin genes and 22 S. aureus infection-related genes in refractory atopic keratoconjunctivitis tissue by RNA-seq analysis, suggesting that lymphoid neogenesis and ...
To assess differential roles of inflammatory cells in pathophysiology of severe atopic keratoconjunctivitis (AKC) and evaluate immunomodulatory effects of topical cyclosporine A (CsA).
To report an outbreak of microsporidial keratoconjunctivitis resulting from a swimming pool in Taiwan.
The aim of the present prospective study was to evaluate the lacrimal fluid concentration of HMGB1 in young patients affected by Vernal Keratoconjunctivitis (VKC) compared to a control group of health...
The skin barrier is a dynamic innate immune organ. This review summarizes the current understanding of how deficiencies associated with atopic dermatitis invite other atopic disorders of the allergic ...
A group of closely related cyclic undecapeptides from the fungi Trichoderma polysporum and Cylindocarpon lucidum. They have some antineoplastic and antifungal action and significant immunosuppressive effects. Cyclosporins have been proposed as adjuvants in tissue and organ transplantation to suppress graft rejection.
A species of gram-negative, aerobic bacteria that is most frequently isolated from bovine eyes in cases of infectious keratoconjunctivitis (KERATOCONJUNCTIVITIS, INFECTIOUS), but also occurs in unaffected eyes and the nasal cavity of cattle.
A disseminated vesicular-pustular eruption caused by the herpes simplex virus (HERPESVIRUS HOMINIS), the VACCINIA VIRUS, or Varicella zoster (HERPESVIRUS 3, HUMAN). It is usually superimposed on a preexisting, inactive or active, atopic dermatitis (DERMATITIS, ATOPIC).
Antigens from the house dust mites (DERMATOPHAGOIDES), mainly D. farinae and D. pteronyssinus. They are proteins, found in mite feces or mite extracts, that can cause ASTHMA and other allergic diseases such as perennial rhinitis (RHINITIS, ALLERGIC, PERENNIAL) and atopic dermatitis (DERMATITIS, ATOPIC). More than 11 groups of Dermatophagoides ALLERGENS have been defined. Group I allergens, such as Der f I and Der p I from the above two species, are among the strongest mite immunogens in humans.
A family of peptidyl-prolyl cis-trans isomerases that bind to CYCLOSPORINS and regulate the IMMUNE SYSTEM. EC 5.2.1.-
The term allergy is used to describe a response, within the body, to a substance, which is not necessarily harmful in itself, but results in an immune response and a reaction that causes symptoms and disease in a predisposed person, which in turn can cau...
Eczema is a common itchy skin disease characterized by reddening and vesicle formation, which may lead to weeping and crusting. It is endogenous, or constitutional. There are five main types; atopic, seborrhoeic, discoid, gravitational or varicose. ...
