Specific association of IL17A genetic variants with panuveitis.

Background/aims: A pathogenic role of Th17 cells in uveitis has become clear in recent years. Therefore, in the present study, we aimed to evaluate the possible influence of the IL17A locus on susceptibility to non-anterior uveitis and its main clinical subgroups.

Methods: Five IL17A polymorphisms (rs4711998, rs8193036, rs3819024, rs2275913 and rs7747909), selected by tagging, were genotyped using TaqMan assays in 353 Spanish patients with non-anterior uveitis and 1851 ethnically matched controls.

Oral flavonoids, chromocarb diethylamine salt and cyaninosides chloride, to eliminate lipoperoxidation postvitrectomy.

This study was undertaken to determine the concentration of malondialdehyde, an end product of lipoperoxidation, in lens and retinal tissue postvitrectomy associated with oral administration of antioxidant flavonoids cyaninosides chloride and chromocarb diethylamine salt or N -acetylcysteine. Fifty adult pigmented rabbits were divided into five groups: (1) controls (normal eyes, malondialdehyde concentration in lens and retina); (2) vitrectomy with BSS Plus (malondialdehyde level measured 2hr after vitrectomy); (3) vitrectomy with BSS Plus and pretreatment with oral cyaninosides chloride 100mg kg day(-1)for 3 weeks (malondialdehyde level measured 2hr after surgery); (4) vitrectomy with BSS Plus and pretreatment with oral chromocarb diethylamine salt 100 mg kg day(-1)for 3 weeks (malondialdehyde level measured 2hr after surgery); and (5) vitrectomy with BSS Plus and pretreatment with oral N -acetylcysteine 200 mg kg day(-1)for 3 weeks (malondialdehyde level measured 2hr after surgery). Lens and retina samples were used to determine malondialdehyde levels using ion-pairing high performance liquid chromatography.
