RESUMO
PURPOSE: To summarize the outcomes of corneal sight rehabilitating surgery in Stevens-Johnson syndrome (SJS). METHODS: This is a retrospective analysis of a consecutive case series. Twenty-four eyes of 18 SJS patients were included in this study. The ocular parameters, surgical procedures, postoperative complications, and additional treatments of the cases were reviewed. RESULTS: A total of 29 corneal sight rehabilitating surgeries, which consists of 9 keratoplasties, 8 Keratolimbal allograft (KLAL) and 12 combined surgeries (keratoplasty and KLAL simultaneously) were performed on the 24 eyes. All patients were treated with glucocorticoid eyedrops and tacrolimus eyedrops for anti-rejection treatment without combining systemic immunosuppression, except two patients who were prescribed prednisone tablets for the management of systemic conditions. The mean follow-up period was 50.6 ± 28.1 months. The optimal visual acuity (VA) (0.74 ± 0.60 logarithm of the minimum angle of resolution [logMAR]) and endpoint VA (1.06 ± 0.82 logMAR) were both significantly better than the preoperative VA (1.96 ± 0.43 logMAR) (95% CI, p = 0.000). 57.1% patients (8/14) were no longer in the low vision spectrum, and 88.9% patients (8/9) were no longer blind. The mean epithelialization time was 7.1 ± 7.6 weeks. The success rate was 86.7%. Additional treatments for improving epithelialization included administration of serum eyedrops (n = 10), contact lens (n = 15), amniotic membrane transplantation (n = 6), and tarsorrhaphy (n = 8). Complications included delayed epithelialization (n = 4, over 12 weeks), glaucoma (n = 11), and severe allograft opacity (n = 4). Only one graft rejection was observed. CONCLUSIONS: Keratoplasty and KLAL can remarkably enhance VA and improve low vision or even eliminate blindness for ocular complications of SJS. The outcome of the surgeries was correlated with the preoperative ocular situation and choice of operative methods.

Purpose: To verify the International Chronic Ocular Graft-Versus-Host Disease (ICCGVHD) Group diagnostic criteria and establish an easy-to-use and reliable diagnosis model for quick identification of chronic oGVHD. Methods: This study included 180 patients (355 eyes) who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) and visited the Peking University Third Hospital Cornea and Ocular Surface Disease Specialist Clinic from July 2020 to February 2021. The proportion of chronic oGVHD was 76.06% (279/355). Results: Five complaints, including eye dryness, photophobia, foreign body sensation, eye redness, and burning sensation; six ophthalmic examinations, including Ocular Surface Disease Index (OSDI) score, corneal fluorescein staining (CFS), tear break-up time (TBUT), Schirmer's test score without anesthesia, conjunctival score, tear meniscus height, and non-ocular GVHD-involved organs were significantly different between patients with chronic oGVHD and control group (p < 0.05). Binary logistic regression (backward LR algorithm) selection demonstrated that three variables retained diagnostic significance for chronic oGVHD: CFS (OR = 2.71 (1.92-3.81), p < 0.001), Schirmer's test score without anesthesia (OR = 0.83 (0.76-0.91), p < 0.001), and conjunctival score (OR = 1.96 (1.13-3.42), p = 0.031). A nomogram for the identification of chronic oGVHD was developed, and its performance was examined using an internal validation cohort (118 eyes). The areas under the curve (AUCs) for the three-variable-based nomogram were 0.976 (95% CI (0.959-0.992), p < 0.01) and 0.945 (95% CI (0.904-0.986), p < 0.01) in the development and internal validation cohorts, respectively. Conclusion: This concise three-variable-based nomogram based on ICCGVHD criteria could serve as an easy-to-use and reliable tool for rapid screening of chronic oGVHD.
RESUMO
PURPOSE: To evaluate corneal epithelial changes and related factors in chronic ocular graft-versus-host disease (oGVHD) patients. METHODS: 21 patients (35 eyes) with chronic oGVHD and 8 patients (12 eyes) without oGVHD after bone marrow transplantation were recruited for assessment involving in vivo confocal microscopy (IVCM) analysis, ocular surface parameter determination and tear cytokine level analysis. The IVCM corneal epithelial scoring system was used to evaluate corneal epithelial changes. RESULTS: There was a significant difference in the corneal epithelial score (p = .001) between the two groups. The corneal epithelial scores were significantly correlated with the corneal fluorescein staining scores (CFS, r = 0.463, p < .001), Schirmer's test (r = -0.389, p = .009) and tear cytokine levels of EGF (r = -0.491, p < .001) and APRIL (r = -0.318, p = .030). CONCLUSIONS: The depth of corneal epithelial defects can be estimated by the CFS. Corneal epithelial changes of chronic oGVHD are considered to be associated with lacrimal deficiency and a lack of EGF.
RESUMO
PURPOSE: The local application of antiinflammatory and immunosuppressive agents is an effective method for the treatment of ocular graft-versus-host disease (oGVHD); however, we noticed that some patients with oGVHD did not respond to topical therapy as well as many others. This study aimed to determine whether tear cytokines were associated with therapeutic effects in oGVHD. METHODS: Forty patients with chronic oGVHD were enrolled and grouped as responders (n = 24) and nonresponders (n = 16) based on the clinical response to 1 month of topical treatment. Tear samples were collected from each participant before and after treatment, and the tear concentrations of 7 cytokines (IL-2, IL-6, IL-8, IL-10, IL-17A, TNF-α, and ICAM-1) were measured using microsphere-based immunoassay analysis. Differences between pretreatment and posttreatment tear samples were analyzed using the Wilcoxon test. RESULTS: No significant differences in ophthalmic symptoms or cytokine levels were observed between responders and nonresponders at baseline. After 1 month of topical treatment, ocular surface parameters (including Ocular Surface Disease Index, National Institutes of Health eye score, best-corrected visual acuity, corneal fluorescein staining score, and fluorescein tear film break-up time) were significantly ameliorated in responders, but not in nonresponders. Moreover, none of the cytokines exhibited significant alteration in nonresponders, whereas the tear levels of IL-6 (P = 0.031) and IL-8 (P = 0.037) exhibited significant decreases in responding patients. CONCLUSIONS: Our results revealed that tear IL-6 and IL-8 levels were significantly altered in response to topical oGVHD treatment.

Graft-versus-host disease (GVHD) is an immune-mediated inflammatory disease resulting from destruction of host tissue by donor immunoreactive cells and occurs in 30% to 70% of post-hematopoietic stem cell transplantation (HSCT) patients. Ocular involvement occurs in up to 60% to 90% of patients with chronic GVHD. T cells have long been recognized as a key driver of alloreactivity in chronic ocular GVHD (oGVHD). However, the role of B-cells has not been elucidated. To further explore the involvement of B-cells in the immune mechanism of chronic oGVHD and to uncover more sensitive biomarker indicators, we conducted this study on the tear cytokine analysis of chronic oGVHD. The study enrolled 18 patients (27 eyes) diagnosed with chronic oGVHD and 11 patients (22 eyes) diagnosed with dry eye disease (DED) as a control group. The microsphere-based immunoassay was used to determine 29 tear cytokines in both groups. Spearman's test was used to analyze the correlation between cytokine levels and different ophthalmic indexes (National Institutes of Health eye score, fluorescein tear film break-up time, corneal fluorescein staining, and Schirmer's test). Receiver operating characteristic curves were used to assess the predictive potential of the identified cytokines for chronic oGVHD. Twenty tear cytokine levels were elevated in patients with chronic oGVHD compared to those with DED (P < .05). Proliferation-inducing ligand (APRIL) and epidermal growth factor showed lower levels in patients with chronic oGVHD. Ultimately, IL-2, 6, and 8, ICAM-1 (CD54), E-selectin (CD62E), neuropilin-1, and B-cell activation factor (BAFF) levels had a strong correlation with ophthalmic indexes and an area under the curve (AUC) > 0.85. BAFF/APRIL exhibited superior diagnostic capabilities (AUC = 0.995; 95% confidence interval, 0.983-1.000). Our study identified IL-2, 6, 8, ICAM-1, CD62E, E-selectin, neuropilin-1, and BAFF as promising tear biomarkers that can indicate the severity of chronic oGVHD. Notably, APRIL/BAFF shows superior diagnostic capabilities, revealing that B cells may play an important role as immune substrates in chronic oGVHD. © 2023 American Society for Blood and Marrow Transplantation.

PURPOSE: To determine the role tear lymphotoxin-α (LT-α) in chronic ocular graft-versus-host disease (oGVHD). METHODS: Twenty-two chronic oGVHD and 17 control tear samples were collected, and commercial test strips were used to detect LT-α concentrations. Concentration differences between patients with and without oGVHD were determined via Mann-Whitney U test. The correlation between LT-α levels and ophthalmic parameters was analyzed using Spearman's test. RESULTS: The concentration of LT-α was significantly lower in oGVHD patients than in controls. LT-α levels were significantly correlated with OSDI, NIH eye score, T-BUT, and CFS among all participants. ROC analysis revealed that the area under the curve of LT-α was 0.847, and the cutoff value for chronic oGVHD diagnosis was 0.203 ng/mL. CONCLUSION: Our study revealed the significant decrease of tear LT-α in oGVHD, and suggested LT-α as a promising marker for chronic oGVHD diagnosis.
