RESUMO
PURPOSE: To evaluate the effectiveness and safety of a novel cyclosporine 0.1% aqueous ophthalmic solution in a large population with vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC). METHODS: A prospective observational postmarketing study was initiated in Japan. A total of 594 patients with VKC or AKC were started on this drug within 1 year after market launch (January 2006) and completed a 6-month follow-up. These patients were observed clinically, and subjective ocular symptoms (itching, discharge, tearing, photophobia, foreign body sensation, and pain), objective signs (hyperemia, swelling, follicle, papillae, and giant papillae for the tarsal conjunctiva; hyperemia and edema for the bulbar conjunctiva; Trantas dots and swelling for the limbus; and corneal involvement), and adverse events were recorded. RESULTS: All scores for symptoms and signs significantly decreased from Month 1 through Month 6 of treatment in both VKC and AKC. Median total symptom scores at baseline, Month 1, and Month 6 were 6, 2, and 1, respectively, for VKC, and 7, 3, and 2, respectively, for AKC. Similarly, median total sign scores were 12, 7, and 5, respectively, for VKC, and 14, 10, and 7, respectively, for AKC. The percentage of patients able to complete topical cyclosporine 0.1% therapy within 6 months due to alleviation of symptoms was higher for VKC (44.4%) than for AKC (21.9%). In both VKC and AKC, approximately 30% of steroid users were able to discontinue topical steroids. Adverse drug reactions (ADRs) were found in 12.0% of patients, and the most common ADR was eye irritation (4.4%). Infectious corneal complications were observed in five AKC patients, including two cases of bacterial corneal ulcer and three cases of herpetic keratitis; all of these patients were concomitantly using topical steroids. CONCLUSIONS: Topical cyclosporine 0.1% is an effective and safe treatment for VKC and AKC.

PURPOSE: High resolution (four-digit) allele genotyping was used to determine the association of the HLA-A and -B alleles with Behçet's disease (BD) in Japanese patients. We also analyzed our results for the association of these alleles with the individual clinical features of BD. SUBJECTS AND METHODS: We enrolled 389 Japanese BD patients and 254 healthy controls in this study. Genotyping of the HLA-A, -B alleles was performed by the PCR-SSOP-Luminex method and the phenotype frequencies of the HLA-A, and -B alleles were estimated. RESULTS: Some HLA-A and -B alleles were significantly associated with BD. When we recalculated the phenotype frequencies for the HLA-B*51-negative subjects to exclude the effects of the linkage disequilibrium with the HLA-B*51 allele, HLA-A*2601 was most strongly associated with BD. In addition, we observed a significant association between several clinical features and some alleles, including HLA-A*2602. CONCLUSION: The significant increase of HLA-A* 26 in the BD patients without HLA-B*51 suggests that this allele itself might be one of the primary susceptibility genes involved in the development of BD independently of HLA-B*51.
