Purpose: To evaluate 10-year outcome of infliximab (IFX) treatment for uveitis in Behçet disease (BD) patients using a standardized follow-up protocol.

Design: Retrospective longitudinal cohort study.

Participants: 140 BD uveitis patients treated with IFX enrolled in our previous study.

Human cytomegalovirus (HCMV) infections develop into CMV diseases that result in various forms of manifestations in local organs. CMV-retinitis is a form of CMV disease that develops in immunocompromised hosts with CMV-viremia after viruses in the peripheral circulation have entered the eye. In the HCMV genome, extensive diversification of the UL40 gene has produced peptide sequences that modulate NK cell effector functions when loaded onto HLA-E and are subsequently recognized by the NKG2A and NKG2C receptors.

Article Synopsis
  • Vogt-Koyanagi-Harada (VKH) disease is a systemic inflammatory disorder impacting pigment cell-containing organs, particularly the eye, with strong associations found between the disease and certain HLA-DR4 genetic alleles across various ethnic groups.
  • * A recent study replicated findings from a genome-wide association study (GWAS) in a Japanese population, confirming the significance of two genetic risk factors, IL23R-C1orf141 and ADO-ZNF365-EGR2, through assessments of specific single nucleotide polymorphisms (SNPs).
  • * The meta-analysis showed these SNPs have strong associations with VKH disease susceptibility, indicating that these genetic loci may be crucial in the disease's development.

Article Synopsis
  • The study documents four cases where patients developed new or worsened uveitis after receiving infliximab treatment.
  • The patients included three women with a mean age of 33, and they were treated for various conditions like rheumatoid arthritis and Crohn’s disease.
  • All cases saw improvement in ocular inflammation after discontinuing infliximab and adding other treatments, suggesting that these adverse effects are rare but significant.

: To investigate whether variants in the gene encoding KU-MEL-1 are associated with Vogt-Koyanagi-Harada (VKH) disease in a Japanese population. : We recruited 380 Japanese patients with VKH disease and 744 Japanese healthy controls to genotype seven single-nucleotide polymorphisms (SNPs) in . We also performed imputation analysis of the region and 195 imputed SNPs were included in the statistical analysis.

Purpose: To report two cases of Vogt-Koyanagi-Harada disease (VKH) resistant to systemic corticosteroid therapy, effectively treated with systemic cyclosporine. Case 1: A 52-year-old man diagnosed as VKH was administered oral corticosteroids (40 mg/day), following steroid pulse therapy. Since there was no significant improvement, he underwent a second course of steroid pulse therapy and oral corticosteroid administration (40 mg/day).

Purpose: To determine the effect of low-dose cyclosporine (CyA) treatment for patients with chronic Vogt-Koyanagi-Harada (VKH) disease resistance to systemic corticosteroid treatment. Methods: We retrospectively evaluated patients diagnosed with chronic VKH disease resistance to systemic corticosteroid treatment at Japan Community Health Care Organization (JCHO) Osaka Hospital between March 2013 and March 2016. We followed the observation with systemic low-dose CyA (100 mg once daily) treatment of these patients.

Purpose: To study the mechanism of lipopolysaccharide (LPS) tolerance in a rat model of footpad injection endotoxin-induced uveitis (EIU).

Methods: EIU was produced by footpad injection of 1 mg/kg LPS in male Sprague-Dawley rats. Four experiments were undertaken in this study.

The aim of this study was to evaluate the new developed sialyl-Lewis X conjugated liposome (sLe XL) as a site-directed delivery system to activated endothelial cells in vivo using a murine experimental autoimmune uveoretinitis (EAU) model. Four types of nanoparticles were prepared using this liposome: fluorescein isothiocyanate (FITC) labeled sLe XL (F-sLe XL) and its vehicle (F-L), sLe XL containing dexamethasone (d-sLe XL) and liposome without sLe X containing dexamethasone (d-L). First, after a bolus injection of F-sLe XL or F-L into EAU mice, sequential tissue accumulation of FITC was examined by confocal laser scanning microscopy.
