RESUMO
BACKGROUND: Thyroid eye disease (TED) can result in proptosis and ocular misalignment, leading to eye pain, diplopia, and vision loss. Teprotumumab, a humanized antibody against insulin-like growth factor 1 receptor, was approved in 2020 for the treatment of TED. The purpose of this study was to describe the effect of a full course of teprotumumab on ocular misalignment. METHODS: The medical records of patients who underwent treatment with teprotumumab for active moderate-to-severe TED at a single institution from April 2020 to September 2023 were reviewed retroactively. Sensorimotor examination was performed at each visit using simultaneous prism-cover testing. Demographic information and previous history of radioactive iodine, steroids, strabismus surgery, and smoking were extracted from the record for analysis. RESULTS: A total of 19 patients were treated during the study period, of whom 11 had strabismus and diplopia. The initial absolute horizontal misalignment in these 11 was 6.0Δ ± 1.5Δ, vertical misalignment was 7.7Δ ± 2.4Δ, and total misalignment was 11.5Δ ± 2.0Δ. On completion of treatment, these measurements decreased by 2.0Δ ± 1.5Δ, 2.2Δ ± 1.0Δ, and 3.2Δ ± 1.6Δ, respectively (P = 0.10, 0.02, and 0.04, resp.). Eight patients (73%) had a decrease in their strabismus, and 5 (46%) reported complete resolution of their diplopia at the final visit. No factors were predictive of which patients would have resolution of their misalignment. Of the remaining 3 patients who had no improvement in ocular alignment, 2 (66%) underwent strabismus surgery. Of the 8 patients with improvement of strabismus, only a single patient (13%) underwent strabismus surgery for persistent diplopia. CONCLUSIONS: In our study cohort, a full course of teprotumumab coincided with complete resolution of diplopia in 46% of patients and a decrease in strabismus in 73% of patients.

Purpose: While corneal transplantation is known to have a potential risk of transmission of variant Creutzfeldt-Jacob Disease (vCJD), the magnitude of this risk has not been quantified. Observations: A case report is presented of a 73 year-old man with a penetrating keratoplasty graft from corneal tissue that was recalled after transplantation due to risk of vCJD because it was later discovered that the donor had traveled to the United Kingdom (UK). Probabilities of vCJD transmission were extrapolated using Creutzfeldt-Jacob Disease (CJD) mortality (incidence) rate, all-cause death rate, and rate of recovery for intended transplantation. Conclusions: An overestimate of the risk of transplanting a cornea infected with vCJD in 2018 was 1 in 940,000. The true risk of vCJD transmission would be even lower due to an incomplete infectivity rate. We conclude that the risk of transmission of latent vCJD by corneal transplantation from a donor who traveled to the UK from 1980 to 1996 is exceedingly low.
RESUMO
Background: Recurrence of herpetic keratitis following vaccination has been documented following vaccination with the Zostavax, trivalent flu, hepatitis A, and rabies vaccines. The USFDA and WHO have acknowledged that the novel COVID-19 vaccines similarly have a risk of reactive immunologic-based inflammation, namely, myositis, pericarditis, and Guillain-Barré syndrome. Case Presentation. We present two patients with latent herpetic keratitis who experienced reactivation of keratitis within weeks of COVID-19 vaccination despite prolonged periods of prior latency. A 52-year-old healthy male with no herpes simplex virus (HSV) keratitis recurrences in two years developed visual decline and patchy stromal haze within 24-48 hours of receiving the second Pfizer-BioNTech (COVID-19 BNT162b2) vaccine. A 67-year-old female with chronic neurotrophic keratitis developed her most severe exacerbation of herpes zoster keratitis in over 10 years occurring 2-3 weeks after her first Moderna (mRNA-1273) vaccine, which was later complicated by bacterial superinfection. Conclusions: The COVID-19 vaccines work by generating both adaptive humoral and cellular immune responses in humans, including elevation of anti-spike neutralizing antibody titers, antigen-specific CD4+ and CD8+ T-cell responses, and increased levels of proinflammatory cytokines such as interferon gamma (IFNγ). The general activation of the T-cell-mediated immune response and proinflammatory cytokines such as IFNγ may underlie the role of the COVID vaccines in reactivation of herpetic stromal keratitis and the clinical findings in our reported cases.
RESUMO
PURPOSE: To report the microbiological spectrum, antimicrobial resistance patterns, and visual outcomes in patients with endogenous endophthalmitis (EE). METHODS: This was a retrospective study of 50 patients with culture-positive EE managed in a tertiary referral center between October 2009 and 2019. Clinical, microbiology analysis, and antimicrobial resistance were reviewed. A multivariable linear regression analysis was used for identifying risk factors associated with worse visual outcomes. RESULTS: Fifty organisms were identified, 62% bacterial and 38% fungal. The most common bacterial organism was Staphylococcus aureus (75% methicillin resistant), and Candida was the most common fungal species. Multidrug resistance was observed in methicillin-resistant Staphylococcus aureus (MRSA) isolates against clindamycin, daptomycin, and fluoroquinolones. The distributions of the final visual acuity (VA) between the bacterial and fungal groups were significantly different, and the visual outcomes in the bacterial group tended to be worse (p = 0.01). The distributions of enucleation status were significantly higher in bacterial EE (35%) than fungal EE (5.3%) (p = 0.02). Results from the multivariable linear regression analysis revealed that older age was significantly associated with worse visual outcome (coef = 0.03; p = 0.02), while fungal infections were associated with better outcomes (coef = - 0.87; p = 0.01). Intravenous drug use (coef = 0.87; p = 0.054) was a marginally significant factor associated with worse visual outcomes. CONCLUSION: There was a higher prevalence of bacterial organisms than fungal species among EE. Bacterial EE was associated with worse visual outcomes and higher enucleation rates than fungal EE. Multidrug resistance was prevalent among MRSA isolates. Older age and intravenous drug use may be factors associated with poor prognosis.

PURPOSE: To explore how endophthalmitis presented from 2009 to 2019 in a West Virginia population particularly affected by the national opioid crisis. The analysis explores the relationship between the type of endophthalmitis and mortality, accounting for factors including age, gender, type of organism, and intravenous drug use (IVDU). METHODS: The electronic health record of West Virginia University (WVU) Medicine was queried for all patients managed for endophthalmitis from October 2009 to October 2019. For each of the included subjects, age, gender, history of IVDU, culture results, concomitant endocarditis, type of endophthalmitis, and the date of diagnosis were extracted. Mortality data were obtained from WVU's electronic medical record, the Social Security Death Index, and public obituaries. Mortality results were represented by a Kaplan-Meier Survival curve following each patient for one year from the date of diagnosis. Results were analyzed using unadjusted and adjusted Cox Proportional Hazard models. RESULTS: One-year mortality was 14 out of 113 endogenous cases (12.4%) compared to 6 out of 173 exogenous cases (3.5%). Endogenous endophthalmitis cases had significantly higher mortality than exogenous ones within one year of diagnosis (p = 0.0034). The unadjusted Cox proportional hazards model revealed that the type of endophthalmitis (endogenous vs. exogenous) was the only variable with a significant impact on 1-year mortality with a hazard ratio of 3.78 (p = 0.01). However, the hazard ratio for endogenous infections rose to 10.91 (CI 3.544-33.595) when the other variables of age, gender, organism, and IVDU were controlled (p < 0.01). The Cox proportional hazard ratios for age group, gender, organism type, and history of IVDU were not significantly different when adjusted for all other variables. CONCLUSION: Endogenous cases, which were significantly overrepresented in West Virginia, were associated with a significantly higher 1-year mortality rate than the exogenous ones. Age, gender, organism type, and history of IVDU have less, if any, modifying effect on mortality.
