Granulocytapheresis in patients with refractory ocular Behcet's disease.

Intraocular inflammation (uveoretinitis) is one major complication of Behcet's disease (BD) and responds poorly to drug therapy. This open prospective study was to assess the efficacy of selective granulocytapheresis in patients with refractory uveoretinitis of BD. Fourteen patients aged 20-56 years were treated. Granulocytapheresis was done with an Adacolumn filled with cellulose acetate leucocyte carries or beads that adsorb granulocytes and monocytes from the blood in the column. Each patient received 5 Adacolumn sessions at one session/week over 5 consecutive weeks. The study was designed to allow each patient to serve as his or her own control. The total numbers of ocular attacks (OA) were monitored for 6 months before and after 5 Adacolumn sessions. The number of OA (mean +/- SD) per patient for the 6 months before Adacolumn was 4.21 +/- 1.6 and for the 6 months post Adacolumn was 2.93 +/- 1.39 ( P = 0.0275). Nine patients (64%) improved and 5 did not change or worsened. Further, for a sub-group (n = 7) with duration of BD > or =5 years, the number of OA were 4.71 +/- 1.89 for the first 6 months and 2.29 +/- 1.38 for the second 6 months ( P = 0.0054). The corresponding values for a sub-group (n = 7) with duration of BD<5 years were 3.71 +/- 1.25 and 3.57 +/- 1.13, indicating that patients with long duration of BD are better responders. We conclude that granulocytapheresis might be effective and safe for patients with refractory ocular BD. Further studies are necessary to fully evaluate the clinical efficacy of granulocytapheresis for BD.

CXCR2 Expression on neutrophils is upregulated during the relapsing phase of ocular Behcet disease.

PURPOSE: To search for markers of Behcet disease (BD) activity,we measured CXCR1 and CXCR2 levels on the circulating leukocytes of patients suffering from ocular BD. METHODS: Peripheral blood leukocytes were harvested from healthy volunteers (n = 16) and ocular BD patients (n = 35). The patients consisted of 15 individuals in relapsing phase (6 with prednisolone treatment) and 20 individuals in remission phase (9 with prednisolone treatment). Expression of CXC chemokine receptors (CXCRs) on leukocytes (including lymphocytes, monocytes, neutrophils) was measured using flow cytometry. RESULTS: Without prednisolone treatment, CXCR2 expression (on both total leukocytes and neutrophils) in relapsing phase was significantly higher than in remission-phase patients or normal individuals. By contrast, no significant difference was detected in the expression of CXCR1 between any ofthe groups. Importantly, low-dose prednisolone therapy reduced CXCR2 expression on neutrophils. CONCLUSIONS: CXCR2 has a potential role in promot-ing uveitis during ocular attack and might also be a useful marker for disease activity.

[Incidence of endogenous uveitis at Kyushu University Hospital].

PURPOSE: We performed a clinical statistical study on recent patients with endogenous uveitis at the clinic of the Department of Ophthalmology, Kyushu University Hospital. SUBJECTS: We studied 616 patients with endogenous uveitis who first visited the clinic of the Department of Ophthalmology, Kyushu University Hospital, between January 1996 and December 2001. RESULTS AND CONCLUSION: The most frequent clinical entity was sarcoidosis (8.6%), followed by Behçet's disease (8.4%), Vogt-Koyanagi-Harada syndrome (6.5%), human T-lymphotropic virus type I (HTLV-1) uveitis (3.9%), and toxoplasmosis (2.6%). Unclassified uveitis comprised 58.1% in our study. Next we classified the subjects into four age groups; adolescent (0-19 years old), young (20-39 years old), middle-aged (40-59 years old), and elderly (60-years old). We also classified the disease into four groups: uveitis pan, anterior, intermediate, and posterior uveitis, according to the site of inflammation. The most frequent clinical entity was Behçet's disease in the young group, and sarcoidosis in the elderly group. The frequency of unclassified uveitis was high in the adolescent and the elderly groups. As to the anatomic diagnosis of uveitis, panuveitis was most frequent, followed by anterior, posterior, and intermediate uveitis. Finally we investigated the frequency of secondary glaucoma. The frequency in all 616 patients was 19.7%. Secondary glaucoma was more frequent in male patients and more frequent in the middle-aged and the elderly groups.
