[PMID: 38867175 PMCID: PMC11167901 DOI: 10.1186/s12886-024-03506-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 05/29/2024] [Indexed: 06/14/2024] Open
Abstract
BACKGROUND The prevalence of rejection is 10-30% in penetrating keratoplasty (PKP) case, and the rate is higher in cases of high-risk patients. Although using topical corticosteroids is a standard method for management the rejection of post-PKP patients, it may not be sufficiently potent in high-risk patients. Topical administration of tacrolimus (TAC) may be effective in suppression rejection after corneal transplantation. This study aimed to investigate the efficacy and safety of topical TAC in high-risk PKP patients in Japan. METHODS This study was a single centre, single-blinded, randomized controlled trial. Patients with a history of PKP, graft rejection, atopic dermatitis, or deep corneal neovascularisation who underwent PKP were enrolled. They were randomly assigned to receive 0.1% TAC ophthalmic suspension or artificial tear (AT) up to week 52 after surgery. All participants received 0.1% betamethasone up to week 13 after surgery then they received 0.1% fluorometholone up to week 52. The incidence of immunological rejection during the observation period was the main outcome measure in this study. RESULTS Thirty patients were enrolled in this study, and 12 eyes in the TAC group and 13 eyes in the AT group completed the study, respectively. Five out of 30 patients discontinued participation after providing informed consent. No serious adverse effects were developed in patients who received 0.1% TAC ophthalmic suspension. No rejection episodes occurred in the TAC group, while one eye in the AT group had rejection. Graft clarity, best spectacle-corrected visual acuity, intraocular pressure, and corneal endothelial cell density were not significantly different between the TAC and AT groups. CONCLUSION Our results demonstrated that good tolerability of 0.1% TAC ophthalmic suspension. However, we failed to demonstrate its efficacy in preventing immunological rejection in high-risk patients undergoing PKP. TRIAL REGISTRATION This study was first registered in the University Hospital Medical Information Network (UMIN000029669, Date of registration: November 1, 2017). With the enforcement of the Clinical Trial Act in Japan, the study re-registered in the Japan Registry of Clinical Trials (jRCTs031180342, Date of registration: March 18, 2019).

Abstract
PURPOSE The aim of this study was to compare outcomes between topical tacrolimus and oral tacrolimus as the primary calcineurin inhibitor for postoperative immunosuppression after primary keratolimbal allograft (KLAL) transplantation for limbal stem cell deficiency (LSCD). METHODS We performed a retrospective, comparative cohort study at a single tertiary referral center (University of MN) of all patients who underwent primary KLAL between 2014 and 2021. Eyes were grouped into those which received topical tacrolimus as the only calcineurin inhibitor (topical group) and eyes in which patients received oral tacrolimus with or without topical tacrolimus (oral group). Clinical and donor tissue data were obtained and compared between the 2 groups. RESULTS In total, 27 eyes of 22 patients (median age 42 years, range 20-79 years) were included, of which 18 eyes were in the oral group and 9 eyes were in the topical group. The mean follow-up time was 33.2 ± 22.6 months. The most frequent etiology of LSCD was alkaline burn (33.3%). At 36 months, graft failure occurred in 6 eyes in the oral group (33.3%) and 2 eyes in the topical group (22.1%) ( P = 0.57). The failure rate in the oral group was 9.1 per 1000 person-months versus 8.4 per 1000 person-months in the topical group ( P = 0.96). The median improvement in BCVA was logMAR -0.975 and logMAR -0.45 for the oral and topical group, respectively ( P = 0.50). CONCLUSIONS With careful patient selection, topical tacrolimus may be a viable alternative to oral tacrolimus in KLAL.

Abstract
Physiological wound healing of the cornea is a complex process and involves numerous multifactorial tissue processes. A proper wound healing, especially without the formation of light-scattering scars, is essential to preserve the integrity and function of the cornea. Misdirected wound healing is of vast clinical relevance as it can lead to corneal fibrosis and the loss of optical transparency with subsequent reduction of visual acuity, up to blindness. In addition to the understanding of the pathophysiological mechanisms, the knowledge of therapeutic concepts and options for treating corneal wound healing disorders and fibrosis is essential to counteract a permanent damage of the cornea as early as possible. Nowadays, various pharmacological and surgical options are available for treatment. The decision, appropriate selection and indication for the optimal treatment depend primarily on the genesis and clinical appearance of the corneal wound, fibrosis or scar. The treatment of wound healing disorders ranges from the use of topical therapy and supportive measures up to tissue replacement procedures. As long as the mechanical stability of the cornea is intact and wound healing processes are still ongoing, a pharmacological modulation is reasonable, which is discussed in this article.

Abstract
Nanoparticles self-assembled by amphiphilic copolymers for loading hydrophobic molecules are intensively investigated. However, their hydrophobic molecule-loading capacity is low due to the limitation of hydrophobic groups in these copolymers. In this regard, new lysine oligomer-based multi-hydrophobic side chain polymers (MHCPs) are synthesized by polymerization of γ-benzyl-l glutamate N-carboxy anhydride initiated by side-chain primary amino groups in lysine oligomer. Each hydrophobic side chain in MHCPs can be self-assembled by hydrophobic interaction to form multi-hydrophobic-core nanoparticles (MHC-NPs) with silkworm cocoon-, grape cluster-, and butterfly-like shapes (depending on hydrophobic-side-chains lengths). To increase their stability, MHC-NPs are dually self-assembled with polyethylene glycol-polyglutamic acid through charge interaction. Each hydrophobic core in MHC-NPs serves as a carrier for hydrophobic molecules, endowing their nanostructure with high loading capacity. MHC-NPs are employed to load tacrolimus (also known as FK506), and the loading amount is 18% and the loading efficiency is 80%, which are higher than those of previously reported nanomicelles self-assembled by linear amphiphilic copolymers. Topical administration of FK506-loaded nanoparticle (FK506-NP) can significantly prolong retention of FK506 on the eye surface. FK506-NP exhibits higher in vivo immunosuppressive effects than free FK506 and commercial FK506 eye drop, as well as a better protective effect against immunotoxicity in the corneal grafts after keratoplasty.

Abstract
Background To evaluate the efficacy of the topical administration of immunosuppressants and corticosteroids in tapering doses in the management of patients with high-risk keratoplasty. Methods One hundred and six patients treated with topical immunosuppressants (50 eyes in the FK506 group and 56 eyes in the CsA group) and corticosteroid eye drops in tapering doses were enrolled in the study. The rates of rejection episodes, irreversible rejection, graft survival, and related influential factors were evaluated. Results The mean follow-up period was 48.1 ± 7.9 months (range, 36–60 months). The rates of rejection episodes and irreversible rejection were 14.0% and 6.00% in the FK506 group and 37.5% and 7.1% in the CsA group, respectively. Kaplan-Meier survival analysis demonstrated a significantly higher graft survival rate in the FK506 group (81.6%±5.3%, 71.1%±6.3%) compared with that in the CsA group (71.1%±6.3%, 57.5%±7.5%) at 3 and 5 years after surgery (P = 0.006). Multivariate logistic regression revealed that preoperative risk score ≥ 3 (P = 0.016) and endothelial immune rejection (P = 0.033) were risk factors associated with graft survival. Conclusions Topical administration of tacrolimus and corticosteroids in tapering doses is effective in decreasing the incidence of immune rejection in high-risk keratoplasty. Careful instruction of patients on the reasonable use of topical tacrolimus is critical to avoid immune rejection induced by sudden discontinuation of medication.

Abstract
Purpose To evaluate the microstructural corneal changes during acute endothelial graft rejection and following treatment using in vivo confocal microscopy (IVCM). Methods Patients with a clinical diagnosis of severe acute endothelial graft rejection following penetrating keratoplasty were included in this study. IVCM was performed on the 1st day the patient presented with rejection signs and at the time of clinical resolution. Results Twenty-three patients were included in this study. Inflammatory cells appeared as dendritic cells (DCs) and less frequently, as non-DCs in basal epithelial and subbasal areas. Activated keratocytes (AKs) (type 1: large cells with visible cytoplasmic processes; type 2: elongated and spindle-shaped keratocytes) were visible in acute phase. Following resolution, type 1 AKs considerably reduced, but type 2 cells were more often persisted. Multiple types of keratic precipitates (KPs) were also visible in acute phase which resolved following resolution of rejection. Conclusions Acute graft rejection was associated with an increase in the number of DCs, activation of keratocytes, and aggregation of various types of KPs. Inflammatory process subsided in almost all cases, but the IVCM changes did not return to normal early after clinical resolution of rejection.

Abstract
Background Worldwide, corneal transplantation (CT) is the most common type of tissue replacement and the increased rate of corneal graft rejection (CGR) after CT is a critical problem. Corneal endothelium cells (CECs) are often targets of the immune response mediated by graft-attacking effector T cells. However, the molecular mechanism underlying CGR remains poorly understood. Methods The differentially expressed microRNAs (miRNAs) and mRNA of graft-fail corneas were measured by transcriptome sequencing (RNA-Seq). real-time quantitative polymerase chain reaction was used to measure gene expression levels. Western blot and immunofluorescence staining were used to measure protein expression levels. Kaplan-Meier survival curves were constructed to assess corneal graft survival. Hematoxylin and eosin staining was used for histopathological examination. CCK-8 and ELISA staining were used to detect cell viability and inflammatory cytokines levels, respectively. Flow cytometry was used to detect cell apoptosis and the population of Treg and Th17. Transwell migration and wound-healing assays were used to measure cell migration. Results We identified 453 miRNAs and 4,279 mRNAs aberrant expression in the corneas showing CGR. The differentially expressed miR-151-5p and its potential target gene [interleukin 2 receptor subunit alpha (IL-2Rɑ)] were selected from the RNA-Seq microarrays. The levels of miR-151-5p and IL-2Rɑ were respectively downregulated and upregulated in the CGR. The luciferase activity assay suggested that IL-2Rɑ is a target of miR-151-5p in 293 T cells. In addition, the miR-151-5p inhibitor, si-IL-2Rɑ, and oe-IL-2Rɑ transfection tests in CECs further confirmed that miR-151-5p downregulation and IL-2Rɑ overexpression promoted apoptosis of CECs and inhibited CEC migration, tight junction-related protein ZO-1 and Claudin-5 expression, and PI3K/AKT signaling pathway activity; however, downregulation of IL-2Rɑ abolished the inhibitor effect of miR-151-5p. Similarly, upregulation of miR-151-5p alleviated CGR via activation of the PI3K/AKT signaling pathway and balancing of Th17/Treg, and upregulation of IL-2Rɑ abolished the alleviating effect of miR-151-5p. Conclusions Upregulation of miR-151-5p alleviated CGR by activating the PI3K/AKT signaling pathway and balancing Th17/Treg via targeting of IL-2Rɑ, which contributes to improving the results of CT.

Abstract
Purpose To report a case of syphilitic interstitial keratitis successfully managed with topical tacrolimus after the development of steroid-induced intraocular pressure elevation in a pediatric patient. Observations A 4-year-old female with a history of congenital syphilis that was reportedly treated after birth presented with bilateral conjunctival redness, tearing, and photosensitivity. Initial ophthalmic examination revealed corneal vascularization with diffuse haze of the right eye and circumferential vascularization with stromal infiltrates of the left eye. She was diagnosed with bilateral syphilitic interstitial keratitis and initially managed with topical steroids but developed steroid-induced elevation of her intraocular pressure. She experienced several recurrences of keratitis as steroids were tapered. After a recurrence in her right eye, she was treated with topical tacrolimus. Since then, she has remained recurrence-free for almost three years with normal intraocular pressure. Conclusion and importance Tacrolimus represents a novel alternative for the treatment of syphilitic interstitial keratitis, which is particularly useful in patients that develop elevated intraocular pressures in response to long-term treatment with steroid eye drops.

Abstract
PURPOSE To determine the prevalence of survival of corneal grafts and visual outcomes of primary penetrating keratoplasty (PK) in infants with Peters anomaly (PA) in Beijing, China. METHODS Twenty-nine patients (37 eyes) with PA who underwent PK before the age of 1 year were included. Optical correction for all eyes and occlusion therapy of amblyopia for a unilateral opacity were performed 2 weeks after suture removal. All infants underwent assessment of visual acuity after surgery using Teller Acuity Cards. Survival probabilities were estimated using the Kaplan-Meier method and log-rank test. Visual outcomes and prognosis factors were analyzed using the χ2 test. RESULTS The mean age of 29 infants undergoing primary PK was 5.7 ± 2.3 months. The mean follow-up duration was 18.0 ± 3.0 months. Twenty-seven (73.0%) of 37 grafts retained full clarity at final follow-up. Visual acuity above ambulatory was achieved in 67.6% (25/37) and >20/260 was achieved in 48.6% (18/37) of cases. Of all surgical indications, vascularized PA I (50.0%, 6/12) and PA II (18.2%, 2/11) showed a lower proportion achieving visual acuity >20/260 than nonvascularized PA I (71.4%, 10/14) (P = 0.030 < 0.05). There was no significant difference in the prevalence of graft survival and vision outcome between infants younger than 6 months and older than >6 months. CONCLUSIONS For infants with PA who underwent PK, the prevalence of graft survival and visual acuity were related mainly to the indication. The main risk factors were corneal vascularization and an abnormal lens.

Abstract
The aim of the present study was to compare the clinical efficacy between simplified Descemet stripping endothelial keratoplasty (DSEK) and penetrating keratoplasty (PKP) in the treatment of patients with bullous keratopathy (BK). A cohort of 65 patients (65 eyes) with BK recruited between December 2002 and June 2018 was divided into two groups according to the treatment they received: The simplified DSEK group (n=38) and the PKP group (n=27). The best-corrected visual acuity (BCVA) during the follow-up at 1, 3, 6 and 12 months and postoperative complications were all recorded. Furthermore, the graft survival rate after 1 year was recorded. The mean BCVA in the simplified DSEK group was significantly better than that in the PKP group after 1, 3, 6 and 12 months (P<0.05). Furthermore, the 1-year graft survival rate in the simplified DSEK group (91.2%) was significantly higher than that in the PKP group (70.4%; P=0.039). A total of 13 eyes (34.21%) in the simplified DSEK group and 11 eyes (40.74%) in the PKP group were diagnosed with glaucoma; there was no significant difference between the rate of glaucoma diagnosis between the two groups (P=0.591). Graft rejection was observed in 5 eyes (13.16%) of the simplified DSEK group and 8 eyes (29.63%) of the PKP group and the rate of graft rejection did not differ significantly between the groups (P=0.279). Graft infection occurred in 1 eye (2.63%) in the simplified DSEK group and 6 eyes (22.22%) in the PKP group. Simplified DSEK achieved better visual acuity and longer graft survival rates than PKP. The incidence of postoperative secondary glaucoma, graft rejection and graft infection after simplified DSEK was lower than that in the PKP group, but only the incidence of graft infection was significantly different.

Research Progress of Drug Prophylaxis for Lens Capsule Opacification after Cataract Surgery. J Ophthalmol 2020; 2020:2181685. [PMID: 32714607 PMCID: PMC7355348 DOI: 10.1155/2020/2181685] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Accepted: 06/09/2020] [Indexed: 12/29/2022] Open
Abstract
Phacoemulsification combined with intraocular lens (IOL) implantation is the international standard operation procedure for cataract and has been generalized worldwide. However, lens capsule opacification, one of the common complications after cataract surgery, impacts the recovery of patients' visual function to a large extent. Lens capsule opacification has two types, anterior capsule opacification (ACO) and posterior capsule opacification (PCO), according to the location. There is not an accepted approach to treat ACO. Nd : YAG laser capsulotomy, the common treatment of PCO, can effectively improve the vision, but may cause a series of complications and is inappropriate for children who are too young to cooperate with this treatment. It is generally known that the responses of lens epithelial cells (LECs) after cataract surgery, including cell proliferation, migration, and epithelial-mesenchymal transition (EMT), play a key role in the pathogenesis of lens capsule opacification. Scholars found that substantial drugs can reduce the occurrence of lens capsule opacification by inhibiting, clearing, or killing LECs, and made great efforts as well as innovations on the exploration of drug species or modes of administration. This article is a systematic interpretation and elaboration about how to prevent lens capsule opacification after cataract surgery via different drugs.

Literature review and suggested protocol for prevention and treatment of corneal graft rejection. Eye (Lond) 2019; 34:442-450. [PMID: 31332293 DOI: 10.1038/s41433-019-0517-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2018] [Revised: 05/12/2019] [Accepted: 05/20/2019] [Indexed: 11/09/2022] Open
Abstract
Effective prophylaxis and treatment of corneal graft rejection are essential to improve outcomes in corneal transplantation. To date, there has been no standardized protocol published that outlines the optimal prophylactic and therapeutic approaches and, furthermore, the published controlled trials on this subject are limited. Likewise, no study has addressed how the level of antigen exposure varies between different types of keratoplasties. The aim of this paper is to provide a simple evidence-based protocol for the prevention and treatment of corneal graft rejection.
