The paper describes the topical anti-inflammatory activity of 2-(2-hydroxy-4-methylphenyl)aminothiazole hydrochloride (CBS-113 A), a dual inhibitor of cyclooxygenase/lipoxygenase and a potent free radical scavenger. When applied in eye drops (0.01 to 0.1% according to the model used), the drug inhibited inflammation in experimental conjunctivitis and uveitis induced by various procedures (e.g. paracentesis, endotoxin, S-antigen, albumin, Fe2+). The compound also inhibited leukocyte infiltration and histamine release when administered locally in pleural cavity with carrageenan. CBS-113 A could decrease plasma leakage induced by arachidonic acid or platelet activating factor in skin and airway, respectively. However, it was devoid of any activity when administered by systemic route. The compound appears as a potentially useful anti-inflammatory drug, in particular in ophthalmology and as an alternative to glucocorticoids, since it does not present the side effects of these steroids (e.g. worsening of herpetic keratitis).

We tested 3 non steroidal anti-inflammatory drugs in experimental herpes keratitis in order to determine possible pro-infectious consequences. The drugs were Indomethacine, Flurbiprofen and a new non steroidal anti-inflammatory, CBS 113 A, mixed inhibitor of cycloxygenase and lipoxygenase. We studied simultaneously the evolution of the keratitis and viral excretion. We considered that an anti-inflammatory agent had a pro-infectious effect if the keratitis was more serious and/or viral excretion longer in comparison with placebo. We have shown, for the 3 drugs, in comparison with dexamethasone activity, absence of a pro-infectious effect. We compared our results on Flurpiprofen with an other study which gave this anti-inflammatory drug pro-infectious capacities; the concentration used was higher. CBS 113 A, inhibiting the metabolism of arachidonic acid via lipoxygenase and cycloxygenase and thus preventing the formation of metabolitis involved in inflammation (prostaglandins, leukotrienes,...), should have a spectrum of activity wider than that of NSAID. Subject to further studies, these 3 nonsteroidal anti-inflammatory could be used in herpetic kerato-uveitis.

We report a case of severe pigmented keratitis with poor prognosis, caused by Cladorrhinum bulbillosum. Antifungal treatment with topical natamycin and fluconazole eye drops and oral tablet fluconazole failed to heal the ulcer and resulted in perforation. The causative fungus, C. bulbillosum, was identified on the basis of its typical microscopic features and 98% sequence homology to ex-type isolate CBS 304.90 (accession no. FM955448). The results of an in vitro antifungal susceptibility test indicated that the isolate was susceptible to natamycin, amphotericin B, fluconazole and itraconazole. The present case is the third case of keratitis and the second case of human keratitis. Compromised immunity due to liver cirrhosis could lead to a failed prognosis even when the fungal isolate is highly susceptible to antifungal treatment.

The two most common filamentous fungi causing mycotic keratitis are Aspergillus and Fusarium spp. Around 70 Fusarium spp. are involved in causing human infections. In this study, four cases of keratitis in sugarcane farmers in India are being reported, caused by the sugar cane pathogen Fusarium sacchari, a species of the Fusarium fujikuroi species complex. Fusarial keratitis was established by potassium hydroxide/Calcofluor white wet mounts and fungal culture of corneal scrapings on conventional media. Final identification was done by genetic sequencing at CBS-KNAW, Utrecht, The Netherlands. The antifungal susceptibility testing was done using broth microdilution method as per CLSI document M38-A2. Four cases of F. sacchari keratitis were identified. Three of them had trauma with sugarcane leaves, whereas one sugarcane farmer reported trauma by vegetative matter. The morphological similarities among various Fusarium species warrant use of molecular methods for identification of cryptic species. A wide distribution of sugarcane farming could be the possible explanation for emergence of F. sacchari keratitis in India.
