Changes of peripheral blood Th cytokines in acute anterior uveitis and their relationships with recurrence

Acute anterior uveitis (AAU) can cause great pain to patients. Th cytokines in peripheral blood are significantly changed in these patients, including serum interleukin-23 (IL-23), interleukin-17 (IL-17), interleukin-4 (IL-4), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) increase. However, the relationship between Th cytokines and recurrence of AAU is still unclear. Ninety-two cases of AAU were enrolled from January 2020 to April 2022 in our hospital (observation group). Levels of peripheral blood Th cytokines were detected, which were compared between acute and remission stages. After 6 months of follow-up, the relationships between Th cytokines in peripheral blood and recurrence in the observation group were analyzed. The prediction of Th cytokines on recurrence was analyzed. (1) The recurrence rate was 25.00%, and there were no statistical differences in the serum IL-23, IL-17, IL-4, IFN-γ, TNF-α and TGF-β 1 levels between patients with bilateral disease and unilateral disease (P < 0.05). (2) The serum IL-23, IL-17, IL-4, IFN-γ, TNF-α and TGF-β 1 levels of recurrence patients were higher than those of non-recurrence (t = 2.971, 5.357, 2.197, 2.766, 4.395, 2.983, P < 0.05). (3) The serum IL-23, IL-17, TNF-α levels were risk factors for recurrence (OR = 1.035, 1.210, 1.155, P < 0.05). (4) There were positive relationships between serum IL-23, IL-17, IL-4, IFN-γ, TNF-α and TGF-β 1 levels and recurrence (r = 0.317, 0.526, 0.248, 0.304, 0.480, 0.325, P < 0.05).            .

Two Year Outcomes of Trabeculectomy in Cytomegalovirus Anterior Uveitis with Uncontrolled Intraocular Pressure

PURPOSE

To describe the two-year outcome of trabeculectomy in cytomegalovirus(CMV) anterior uveitis(AU).

METHODS

Records of 29 eyes of 29 consecutive CMV AU patients undergoing MMC-augmented trabeculectomy for uncontrolled IOP despite maximal tolerated topical medications were retrospectively reviewed. Treatment success was defined as IOP≤21 mmHg with same or reduced number of IOP-lowering medications compared to baseline, without systemic acetazolamide or further interventions for uncontrolled IOP.

RESULTS

Treatment success was 79.3% (23/29) at 24 months. Both median IOP and number of IOP-lowering medications dropped significantly from baseline (p < .01 and p < .001, all time-points, Wilcoxon sign-rank test, respectively), with 63.2% and 19.0% reduction in AU relapse/year and steroid use(p = .001 and 0.03, respectively), without sight-threatening sequelae. At 24 months, AU frequency was not significantly different between successful cases with and without ≥12-month use of topical ganciclovir (p = .51, Mann-Whitney U test).

CONCLUSION

MMC-augmented trabeculectomy was efficacious for IOP control in nearly 80% of CMV AU cases over two years.
