In vitro antimicrobial activity of diacerein on 76 .

Antimicrob Agents Chemother 2019 Feb 4. Epub 2019 Feb 4.

Henan Provincial People's Hospital and People's Hospital of Zhengzhou University, Henan Eye Institute, Henan Eye Hospital, Zhengzhou, 450003, China.

Bacterial keratitis is an aggressive infectious corneal disease. With the continuing rise in antibiotic resistance and a decline in the discovery of new antibiotics, new antimicrobial drugs are now required. In the present study, we determined the antibacterial activity of diacerein, an anti-inflammatory drug, against 76 Gram-positive cocci isolated from bacterial keratitis patients in vitro and anti- activity in mouse bacterial keratitis model in vivo.

The Persistent Dilemma of Microbial Keratitis: Global Burden, Diagnosis, and Antimicrobial Resistance.

Surv Ophthalmol 2018 Dec 24. Epub 2018 Dec 24.

Department of Ophthalmology, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts, USA; Infectious Disease Institute, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Microbial keratitis (MK) is a potentially blinding condition which must be treated emergently to preserve vision. Although long recognized as a significant cause of corneal blindness, our understanding of its true global scale, associated burden of disease, and etiological patterns remains somewhat limited. Current epidemiological data suggests that MK may be epidemic in parts of the world--particularly within South, South-East and East Asia--and may exceed two million cases per year world-wide.

The Schepens Eye Research Institute, Department of Ophthalmology, Harvard Medical School, 20 Staniford Street, Boston, MA, USA. Electronic address:

Neutrophil-mediated inflammation plays a critical role in corneal damage following injury or infection. Previous studies demonstrated that membrane-bound FasL (mFasL) induces neutrophil chemokine production. However, the extracellular domain of mFasL is normally cleaved by matrix metalloproteinases to release a soluble form of FasL (sFasL) and sFasL antagonizes mFasL-mediated chemokine production.

Impact of topical corticosteroid pretreatment on susceptibility of the injured murine cornea to Pseudomonas aeruginosa colonization and infection.

Exp Eye Res 2019 Feb 19;179:1-7. Epub 2018 Oct 19.

School of Optometry, University of California, Berkeley, CA, USA; Vision Science Program, University of California, Berkeley, CA, USA; Graduate Groups in Microbiology, And Infectious Diseases & Immunity, University of California, Berkeley, CA, USA. Electronic address:

Research with animal models of Pseudomonas aeruginosa keratitis has shown that use of a topical corticosteroid alone against an established infection can significantly increase the number of colonizing bacteria or worsen clinical disease. Moreover, retrospective analysis has suggested that corticosteroid use in humans is associated with an increased risk of keratitis in eyes with pre-existing disease. Thus, while corticosteroids are often used to reduce ocular inflammation in the absence of infection, the risk of opportunistic infection remains a concern. Read More

Concurrent Microbial Keratitis and Nasolacrimal Duct Obstruction: Concordance, Etiopathogenesis, and Outcome.

Cornea 2019 Jan;38(1):84-88

Ophthalmic Plastic and Reconstructive Surgery Service, L. V. Prasad Eye Institute, Bhubaneswar, Odisha, India.

Purpose: Nasolacrimal duct obstruction (NLDO) is believed to be a risk factor for microbial keratitis (MK). The primary objective of this study was to look at microbiological concordance between corneal scraping and lacrimal sac flora in patients with concurrent MK and NLDO. The secondary objective was to compare microbiological isolates from MK and NLDO, MK alone, NLDO alone, and healthy subjects. Read More

Universiti Kuala Lumpur, Malaysian Institute of Chemical and Engineering Technology, Lot 1988 Kawasan Perindustrian Bandar Vendor, Taboh Naning, 78000, Alor Gajah, Melaka, Malaysia.

Microbial keratitis is the infection caused by pathogenic microorganisms that commonly occurs among the contact lens users. Various antimicrobial compounds were coated on contact lenses to kill keratitis causing microorganisms, however these compounds caused several adverse side effects. Hence, the aim of this study is to develop a silicone hydrogel contact lens coated with phomopsidione nanoparticle that inhibit keratitis causing clinical isolates. Read More

Thymosin Beta-4 and Ciprofloxacin Adjunctive Therapy Improves -Induced Keratitis.

Cells 2018 Sep 20;7(10). Epub 2018 Sep 20.

Department of Ophthalmology, Visual & Anatomical Sciences, Wayne State University School of Medicine, Detroit, MI 48201, USA.

With increasing multidrug resistance and contraindication for corticosteroid use, the goal of this study was to develop thymosin beta-4 (Tβ4) as an adjunctive therapy to antibiotics for the treatment of bacterial keratitis that effectively promotes enhanced wound healing, host defense, and inflammation resolution. Disease outcome was assessed by clinical score, slit lamp photography, and histopathology. Cytokine profile, bacterial load, PMN infiltration, and Griess and reactive oxygen species (ROS) levels were determined. Read More

Department of Ophthalmology, Visual and Anatomical Sciences, Wayne State University School of Medicine, Detroit, Michigan. Electronic address:

Ischemia is associated with the pathogenesis of retinal disease, including diabetic retinopathy and glaucoma. As a result, the retinal ischemia/reperfusion injury model has been used to study neurovascular changes. Historically, murine models of retinal disease are established in C57BL/6J (B6) mice, which have been described as type 1-dominant responders. Read More
