ABSTRACT
PURPOSE: To evaluate the efficacy of an antiherpetic vaccine in recurrent herpetic ocular infections. METHODS: Twenty patients with herpes simplex virus 1-related recurrent keratitis/keratouveitis were prospectively enrolled and randomly assigned to receive either a specific vaccination with heat shock-inactivated herpes simplex virus type 1 (10 patients) or to be observed as controls (10 patients). The number, duration, and anatomic localization of relapses were recorded in all the patients for 12 months before inclusion in the study and for a similar period after the assignment of each subject to vaccine or control group. RESULTS: In the vaccine group, we observed a reduction both in the number (p = 0.016) and average duration (p = 0.050) of recurrences, whereas in the control group, no significant change was found comparing a 12-month period before and after inclusion in the study. The comparison between the two groups highlighted a significant reduction in the number (p = 0.013) and average duration (p = 0.051) of relapses in treated subjects, who did not show any significant vaccine-induced side effects. CONCLUSION: The use of a vaccination with heat shock-inactivated herpes simplex virus 1 seems to be able to reduce the number and duration of relapses in herpes simplex virus 1-related keratitis/keratouveitis.

PURPOSE: To study the frequencies of human leukocyte antigen (HLA) specificities in Italian patients with Vogt-Koyanagi-Harada disease and to correlate the presence of each specificity to the clinical features. METHODS: Human leukocyte antigen specificities were determined by standard microlymphocytotoxicity assay in 16 patients with Vogt-Koyanagi-Harada disease and compared with HLA specificities of 116 healthy controls. RESULTS: HLA-DR4 was statistically related to Vogt-Koyanagi-Harada disease (P = .0063), whereas only a trend toward a significant association between the disease and HLA-B41 was found (P = .06). HLA-DQ1 was detected in a disproportionate number of controls (68.9%) compared with patients (37.5%). CONCLUSIONS: HLA-DR4 was significantly related to Vogt-Koyanagi-Harada disease in Caucasian European patients, specifically in Italian patients, as it was described in other racial groups. No clear relation was found between the ophthalmologic and systemic manifestations of Vogt-Koyanagi-Harada disease and the presence of HLA specificities.

A retrospective study on 1,417 uveitic patients referred to the Ocular Immunovirology Service of the University of Rome 'La Sapienza' was carried out to determine the occurrence of the various forms of uveitis. To detect also the possible changing patterns of uveitis during the last 25 years the obtained data were compared with those reported in two previous studies performed by the same author, at the same institution in 1978 and 1985. Anterior uveitis was the most frequent anatomical type of intraocular inflammation (49.12%); intermediate uveitis was diagnosed in 12.42% of all the cases and showed an increased incidence over the years (p < 0.0001). Posterior and diffuse uveitis accounted for 22.1 and 16.37% of the cases. An improvement in diagnostic definition has been confirmed by the significant decrease in the percentage of 'idiopathic uveitis' from 56.8 to 38.1% (p < 0.0001). Associated infectious conditions were detected in 17.43% of the cases. Toxoplasma gondii was the most common etiologic agent of uveitis (6.63%). An associated systemic disease was diagnosed in 15.03% of uveitic patients, and 6% of them were affected with Behçet's disease. Specific ocular diseases and clinical entities increased from 7.8 and 14.68% to 29.42% in the last 25 years (p < 0.0001), the most frequent being pars planitis (11.99%) and Fuchs' heterochromic iridocyclitis (8.32%).

Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a non-hereditary histiocytic proliferative disorder affecting young people, with extranodal manifestations in 28-43% of cases. Eye involvement is infrequent. Lymphoproliferation in the soft tissues of the orbit and in the lids has been reported in 12% of cases but intraocular involvement is rare. We describe the case of a 12-year-old boy affected by Rosai-Dorfman disease with bilateral relapsing uveitis and papilledema that appeared four years before the onset of lymphadenopathy.
