RESUMEN

PURPOSE: To determine the incidence of all-cause and cancer mortality (CM) in association with immunosuppression. DESIGN: Retrospective cohort study at ocular inflammatory disease (OID) subspecialty centers. We harvested exposure and covariate data retrospectively from clinic inception (earliest in 1979) through 2010 inclusive. Then we ascertained overall and cancer-specific mortalities by National Death Index linkage. We constructed separate Cox models to evaluate overall and CM for each class of immunosuppressant and for each individual immunosuppressant compared with person-time unexposed to any immunosuppression. PARTICIPANTS: Patients with noninfectious OID, excluding those with human immunodeficiency infection or preexisting cancer. METHODS: Tumor necrosis factor (TNF) inhibitors (mostly infliximab, adalimumab, and etanercept); antimetabolites (methotrexate, mycophenolate mofetil, azathioprine); calcineurin inhibitors (cyclosporine); and alkylating agents (cyclophosphamide) were given when clinically indicated in this noninterventional cohort study. MAIN OUTCOME MEASURES: Overall mortality and CM. RESULTS: Over 187 151 person-years (median follow-up 10.0 years), during which 15 938 patients were at risk for mortality, we observed 1970 deaths, 435 due to cancer. Both patients unexposed to immunosuppressants (standardized mortality ratio [SMR] = 0.95, 95% confidence interval [CI], 0.90-1.01) and those exposed to immunosuppressants but free of systemic inflammatory diseases (SIDs) (SMR = 1.04, 95% CI, 0.95-1.14) had similar mortality risk to the US population. Comparing patients exposed to TNF inhibitors, antimetabolites, calcineurin inhibitors, and alkylating agents with patients not exposed to any of these, we found that overall mortality (adjusted hazard ratio [aHR] = 0.88, 0.89, 0.90, 1.11) and CM (aHR = 1.25, 0.89, 0.86, 1.23) were not significantly increased. These results were stable in sensitivity analyses whether excluding or including patients with SID, across 0-, 3-, or 5-year lags and across quartiles of immunosuppressant dose and duration. CONCLUSIONS: Our results, in a cohort where the indication for treatment was proven unassociated with mortality risk, found that commonly used immunosuppressants-especially the antimetabolites methotrexate, mycophenolate mofetil, and azathioprine; the TNF inhibitors adalimumab and infliximab, and cyclosporine-were not associated with increased overall and CM over a median cohort follow-up of 10.0 years. These results suggest the safety of these agents with respect to overall and CM for patients treated with immunosuppression for a wide range of inflammatory diseases.

RESUMEN

PURPOSE: To report and illustrate the main clinical presentations of posterior herpetic uveitis. METHODS: Narrative review. RESULTS: The ocular manifestations of posterior herpetic uveitis include different clinical presentations. Herpes simplex and varicella zoster can cause acute retinal necrosis, progressive outer retinal necrosis, and non-necrotizing herpetic retinopathies. Cytomegalovirus has been associated with fulminant retinitis with confluent areas of retinal necrosis and retinal hemorrhages, indolent/granular retinitis, and frosted branch angiitis. These diverse clinical presentations are often associated with specific risk factors and different immunological profiles of the host. CONCLUSIONS: Herpetic viruses can cause posterior uveitis, presenting various clinical findings. Specific ocular manifestations and the immunological status of the host can help to differentiate the various herpetic entities before laboratory tests confirm the diagnosis.

RESUMEN

Importance: The prevalence of irreversible vision impairment in the United States is expected to increase by 2050. Vision rehabilitation is the primary treatment option. Clinical trials have established its efficacy in improving quality of life. Yet studies indicate that patients experience many barriers to accessing low-vision care. Objectives: To examine the rate of referral for low-vision rehabilitation services by resident and attending ophthalmologists for adults with irreversible vision impairment and to assess the knowledge, attitudes, and beliefs of patients about vision rehabilitation. Design, Setting, and Participants: Cross-sectional study with enrollment from June 20, 2016, to January 31, 2017, of 143 adults 18 years or older seen in a publicly funded, comprehensive eye clinic in Jefferson County, Alabama, and having 1 or both eyes with irreversible vision impairment (visual acuity was defined as 20/60 or worse) per the electronic health record. Exposures: Demographic characteristics; patient questionnaire on knowledge, attitudes, and beliefs about vision rehabilitation; general cognitive status (Short Orientation-Memory-Concentration test); depressive symptoms (Patient Health Questionnaire-9); health literacy (Rapid Estimate of Adult Literacy in Medicine, Revised [REALM-R]); and self-reported difficulty in everyday activities. Main Outcomes and Measures: Proportion of patients with irreversible vision impairment who were referred by ophthalmologists to low-vision rehabilitation services per the electronic health record. Results: Of 143 patients enrolled with irreversible vision impairment in 1 or both eyes, the mean (SD) age was 55.4 (11.1) years and 68 (47.6%) were women. Most patients were African American (123 [86.0%]), uninsured (88 [61.5%]), and unemployed (92 [64.3%]); on average, they had normal cognitive status, minor depressive symptoms, and limited health literacy. As noted in the electronic health record, the rate of referral for low-vision rehabilitation services was 11.4% for patients with irreversible bilateral vision impairment (4 of 35 patients) and 1.9% for those with unilateral impairment (2 of 108). Most patients with bilateral (31 of 34 [91.2%]) and unilateral (90 of 97 [92.8%]) impairment indicated that they were bothered by their vision impairment, and most reported difficulty with reading (33 of 34 patients [97.1%] who were bilaterally impaired vs 85 of 104 [81.7%] who were unilaterally impaired). Conclusions and Relevance: Results of this study suggest a need to better educate ophthalmologists and residents in ophthalmology about referrals to low-vision rehabilitation services for patients with irreversible vision impairment.

RESUMEN

Purpose: Extracellular deposits containing hydroxyapatite, lipids, proteins, and trace metals that form between the basal lamina of the RPE and the inner collagenous layer of Bruch's membrane are hallmarks of early AMD. We examined whether cultured RPE cells could produce extracellular deposits containing all of these molecular components. Methods: Retinal pigment epithelium cells isolated from freshly enucleated porcine eyes were cultured on Transwell membranes for up to 6 months. Deposit composition and structure were characterized using light, fluorescence, and electron microscopy; synchrotron x-ray diffraction and x-ray fluorescence; secondary ion mass spectroscopy; and immunohistochemistry. Results: Apparently functional primary RPE cells, when cultured on 10-µm-thick inserts with 0.4-µm-diameter pores, can produce sub-RPE deposits that contain hydroxyapatite, lipids, proteins, and trace elements, without outer segment supplementation, by 12 weeks. Conclusions: The data suggest that sub-RPE deposit formation is initiated, and probably regulated, by the RPE, as well as the loss of permeability of the Bruch's membrane and choriocapillaris complex associated with age and early AMD. This cell culture model of early AMD lesions provides a novel system for testing new therapeutic interventions against sub-RPE deposit formation, an event occurring well in advance of the onset of vision loss.

RESUMEN

TOPIC: To provide recommendations for the use of anti-tumor necrosis factor α (TNF-α) biologic agents in patients with ocular inflammatory disorders. CLINICAL RELEVANCE: Ocular inflammatory diseases remain a leading cause of vision loss worldwide. Anti-TNF-α agents are used widely in treatment of rheumatologic diseases. A committee of the American Uveitis Society performed a systematic review of literature to generate guidelines for use of these agents in ocular inflammatory conditions. METHODS: A systematic review of published studies was performed. Recommendations were generated using the Grading of Recommendations Assessment, Development, and Evaluation group criteria. RESULTS: Numerous studies including controlled clinical trials have demonstrated that anti-TNF-α biologic agents (in particular infliximab and adalimumab) are effective in the treatment of severe ocular inflammatory disease. Based on these studies, the expert panel makes the following recommendations. CONCLUSIONS: Infliximab and adalimumab can be considered as first-line immunomodulatory agents for the treatment of ocular manifestations of Behçet's disease. Infliximab and adalimumab can be considered as second-line immunomodulatory agents for the treatment of uveitis associated with juvenile arthritis. Infliximab and adalimumab can be considered as potential second-line immunomodulatory agents for the treatment of severe ocular inflammatory conditions including posterior uveitis, panuveitis, severe uveitis associated with seronegative spondyloarthropathy, and scleritis in patients requiring immunomodulation in patients who have failed or who are not candidates for antimetabolite or calcineurin inhibitor immunomodulation. Infliximab and adalimumab can be considered in these patients in preference to etanercept, which seems to be associated with lower rates of treatment success.

RESUMEN

To determine if complement anaphylatoxin-mediated inflammation contributes to the development and progression of experimental autoimmune uveitis (EAU), we induced disease in wild type and complement anaphylatoxin receptor-deficient mice (C3a receptor(-/-), C5a receptor(-/-) and C3aR(-/-)/C5aR(-/-)) and evaluated the eyes three weeks post-induction. No differences in disease severity or in disease incidence were seen between wild type controls and anaphylatoxin receptor-deficient mice. Our data indicate that C3a and C5a-mediated functions are not critical to the development of EAU.

RESUMEN

We report two pediatric female patients with systemic lupus erythematosus (SLE) who presented with decreased vision. Both patients were found to have retinal vasculitis and occlusive disease. The first patient also presented with vitreous hemorrhage and later non-arteritic ischemic optic neuropathy. She was treated with panretinal photocoagulation and steroid therapy and later in her disease course was treated with rituximab and cyclophosphamide. Her vision remained decreased. The second patient was treated with rituximab and monthly cyclophosphamide infusions early in her disease course, and her vision improved dramatically. The difference in the presentations and outcomes of these two pediatric patients with SLE highlights the spectrum of severity of SLE retinopathy. We suggest that early recognition of disease and early intervention with B-cell depletion therapy in addition to a traditional cytotoxic agent should be considered in pediatric patients with SLE and occlusive retinopathy.

RESUMEN

BACKGROUND: This study aims to evaluate the effect of oral statin medication use on the subsequent development of ocular inflammatory disease (OID). A retrospective nested case-control study was carried out on patient records from the Birmingham Veterans Affairs Medical Center. All male patients with a new diagnosis of OID over a 5-year period were included. Ten control subjects (without OID) were age-matched to each OID case. Prescription files of all subjects were queried for statin use. Information on selected comorbid medical conditions was also obtained. Conditional logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for risk of OID development in the context of statin use, controlling for comorbid conditions. RESULTS: Ninety-two incident cases of OID were identified. A trend toward a reduction in the risk of new OID development was found in patients that used statins compared to those that did not (OR 0.50, 95% CI 0.20 to 1.23, p = 0.13). The longer the duration of statin use, the greater is the effect. CONCLUSIONS: Use of oral statins may be associated with a reduced risk for the development of OID. This reduced risk increases with increasing duration of use. Larger clinical studies would be required to definitively establish the effectiveness of statins in lowering the incidence of OID.

RESUMEN

PURPOSE: Lipofuscin contained in the retinal pigment epithelium (RPE) is the main source of fundus autofluorescence (FAF), the target of an imaging method useful for estimating the progression of geographic atrophy (GA) in clinical trials. To establish a cellular basis for hyperfluorescent GA border zones, histologic autofluorescence (HAF) was measured at defined stages of RPE pathologic progression. DESIGN: Experimental study. PARTICIPANTS AND CONTROLS: Ten GA donor eyes (mean age ± standard deviation, 87.1 ± 4.0 years) and 3 age-matched control eyes (mean age ± standard deviation, 84.0 ± 7.2 years) without GA. METHODS: The 10-micrometer-thick sections were divided into zones of RPE morphologic features according to an 8-point scale. Any HAF excited by 488 nm light was imaged by laser confocal microscopy. The HAF intensity summed along vertical lines perpendicular to Bruch's membrane at 0.2-µm intervals served as a surrogate for FAF. Intensity profiles in 151 zones were normalized to grade 0 at a standard reference location in each eye. Cross-sectional area, mean, and sum autofluorescence for individual RPE cells were measured (cellular autofluorescence [CAF]). MAIN OUTCOME MEASURES: Statistically significant differences in intensity and localization of HAF and CAF at defined stages of RPE morphologic progression for GA and control eyes. RESULTS: The RPE morphologic features were most abnormal (cell rounding, sloughing, and layering; grade 2) and HAF intensity profiles were highest and most variable immediately adjacent to atrophic areas. Peaks in HAF intensity frequently were associated with vertically superimposed cells. The HAF value that optimally separated reactive RPE was 0.66 standard deviations more than the mean for uninvolved RPE and was associated with a sensitivity of 75.8% and a specificity of 76.3%. When variable cell area was accounted for, neither mean nor sum CAF differed significantly among the RPE pathologic grades. CONCLUSIONS: Areas with advanced RPE alterations are most likely to exhibit clinically recognizable patterns of elevated FAF around GA, but may not predict cells about to die, because of vertically superimposed cells and cellular fragments. These data do not support a role for lipofuscin-related cell death and call into question the rationale of treatments targeting lipofuscin.

RESUMEN

PURPOSE: To assess the current burden of ocular toxocariasis (OT) and to gain knowledge regarding the diagnostic and treatment practices used in the ophthalmologic community in the United States. DESIGN: Web-based, cross-sectional survey. PARTICIPANTS: Subspecialty ophthalmologists who are currently practicing in the United States. METHODS: An electronic survey was sent to 3020 ophthalmologic subspecialists belonging to the American Uveitis Society (AUS), the American Society of Retina Specialists (ASRS), or the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) to capture demographic, clinical, diagnostic, and treatment data on patients with OT seen in their practices between September 2009 and September 2010. MAIN OUTCOME MEASURES: The demographic, epidemiologic, and clinical characteristics of each reported patient with OT. RESULTS: A total of 159 patients with OT were reported by 559 respondents (19%). The median patient age was 11.5 years (range, 1-66 years). Seventy-two patients (45%) with OT lived in the Southern region of the United States. Thirty-one (69%) of 45 patients with OT owned a dog or cat. Vision loss was reported in 46 (85%) of 54 patients with OT; 32 (71%) of 45 patients had permanent vision loss, 13 patients (29%) had temporary vision loss, and duration of vision loss was unreported for 1 patient. Of the 32 patients with OT with permanent vision loss, 30 (94%) had a subretinal granulomatous mass/scar, peripheral granuloma with traction bands, or posterior pole granuloma noted on ophthalmologic examination. Subretinal granulomatous mass/scar, vitritis, and scotoma were the most common ophthalmologic signs found on examination of patients with OT. CONCLUSIONS: Ocular toxocariasis continues to occur in the United States, where it affects mainly children and causes permanent vision loss in many patients. Healthcare professionals should counsel patients and their family members about prevention strategies in an effort to decrease infection rates and morbidity due to Toxocara. Further improvement of diagnostic and treatment tools is needed to assist ophthalmologists in treating patients with OT.

RESUMEN

In geographic atrophy (GA), the non-neovascular end stage of age-related macular degeneration (AMD), the macular retinal pigment epithelium (RPE) progressively degenerates. Membrane cofactor protein (MCP, CD46) is the only membrane-bound regulator of complement expressed on the human RPE basolateral surface. Based on evidence of the role of complement in AMD, we hypothesized that altered CD46 expression on the RPE would be associated with GA development and/or progression. Here we report the timeline of CD46 protein expression changes across the GA transition zone, relative to control eyes, and relative to events in other chorioretinal layers. Eleven donor eyes (mean age 87.0 ± 4.1 yr) with GA and 5 control eyes (mean age 84.0 ± 8.9 yr) without GA were evaluated. Macular cryosections were stained with PASH for basal deposits, von Kossa for calcium, and for CD46 immunoreactivity. Internal controls for protein expression were provided by an independent basolateral protein, monocarboxylate transporter 3 (MCT3) and an apical protein, ezrin. Within zones defined by 8 different semi-quantitative grades of RPE morphology, we determined the location and intensity of immunoreactivity, outer segment length, and Bruch's membrane calcification. Differences between GA and control eyes and between milder and more severe RPE stages in GA eyes were assessed statistically. Increasing grades of RPE degeneration were associated with progressive loss of polarity and loss of intensity of staining of CD46, beginning with the stages that are considered normal aging (grades 0-1). Those GA stages with affected CD46 immunoreactivity exhibited basal laminar deposit, still-normal photoreceptors, and concomitant changes in control protein expression. Activated or anteriorly migrated RPE (grades 2-3) exhibited greatly diminished CD46. Changes in RPE CD46 expression thus occur early in GA, before there is evidence of morphological RPE change. At later stages of degeneration, CD46 alterations occur within a context of altered RPE polarity. These changes precede degeneration of the overlying retina and suggest that therapeutic interventions be targeted to the RPE.

RESUMEN

Attachment by ticks to ocular surfaces is uncommon, but has been reported. The objective of this article is to describe a case of conjunctival tick attachment and a method for removal by conjunctival excision. A 39-year-old man presented to the Emergency Department with a complaint of foreign-body sensation in his right eye. He was found to have a live tick embedded in his conjunctiva. The tick was removed en bloc with surrounding conjunctiva by an ophthalmologist. The arthropod was identified as the larval stage of the Lone Star tick (Amblyomma americanum). The patient did not experience any systemic illnesses or adverse sequelae. Attachment of ticks to the conjunctiva is unlikely to result in disease transmission when the larval stage is involved. However, removal by excision of a surrounding block of conjunctiva is recommended to ensure complete removal of all tick body parts.

RESUMEN

PURPOSE: To report on the presentation and treatment of a patient with infectious posterior segment uveitis because of infection with Rickettsia rickettsii. METHODS: Interventional case report. We conducted a retrospective chart review of a 39-year-old man who presented with a history of acute vision loss in his right eye over a 6-day period. Vision at presentation in the involved eye was 2/200, with mild conjunctival injection, trace anterior chamber cell, moderate vitritis, localized retinitis and retinal hemorrhages, and severe macular edema. The left eye had 20/20 vision and was normal on examination. History was notable for a tick bite followed by high fevers, 1 month before presentation, at which time his family physician diagnosed mononucleosis syndrome with low platelets. RESULTS: A serum Rickettsia rickettsii test was positive. He was treated with oral doxycycline followed by corticosteroids. Vision gradually improved to 20/20 with minimal residual metamorphopsia. CONCLUSION: Only ten cases of Rocky Mountain spotted fever-related uveitis have been reported. The current case is unique because of the delayed onset of ophthalmic complications after the tick bite, its unilateral nature, dramatic improvement in acuity after treatment, and lack of associated rash.

RESUMEN

Sympathetic ophthalmia (SO) is a well-known but rare autoimmune disease in which the sympathizing eye suffers granulomatous panuveitis after trauma to the fellow eye. An unusual case of SO occurring 32 years after trauma to the fellow eye, and 1 year after unsuccessful vitrectomy/scleral buckle repair of an acute retinal detachment in the inciting eye was presented. An optical coherence tomography imagery of Dalen-Fuchs nodules, not previously reported, and rare angiographic imaging of SO in its acute phase was demonstrated.

RESUMEN

PURPOSE: To determine the frequency of occurrence of limited clinical features which distinguish patients with Vogt-Koyanagi-Harada (VKH) disease from those with non-VKH uveitis. DESIGN: Comparative case series. PARTICIPANTS: We included 1147 patients. METHODS: All patients with bilateral ocular inflammatory disease presenting to any of 10 uveitis centers in the 3-month period between January 1 and March 31, 2006 (inclusive), were asked to participate. The clinical and historical features of disease were obtained from the participants via direct interview and chart review. Patients were stratified based on whether they were diagnosed with VKH disease or non-VKH uveitis for statistical analysis. MAIN OUTCOME MEASURES: Presence or absence of various clinical features in the 2 populations. RESULTS: Of 1147 patients, 180 were diagnosed with VKH disease and 967 with non-VKH uveitis. Hispanics and Asians were more likely to be diagnosed with VKH than non-VKH disease compared with other ethnicities. In acute disease, the finding of exudative retinal detachment was most likely to be found in VKH disease with a positive predictive value (PPV) of 100 and negative predictive value (NPV) of 88.4, whereas in chronic disease, sunset glow fundus was most likely to be found, with a PPV of 94.5 and NPV of 89.2. CONCLUSIONS: Numerous clinical findings have been described in the past as important in the diagnosis of VKH. The current study reveals that of these, 2 are highly specific to this entity in an ethnically and geographically diverse group of patients with nontraumatic bilateral uveitis. These clinical findings are exudative retinal detachment during acute disease and sunset glow fundus during the chronic phase of the disease.

RESUMEN

PURPOSE: To report seven cases of uveitis occurring in patients with autoimmune hepatitis (AIH), raising the possibility that uveitis may be an extrahepatic feature of AIH. DESIGN: Multicenter, retrospective, observational case series of patients with AIH and uveitis. METHODS: One index case was identified at Oregon Health & Science University. Further cases were identified by a web-based survey of members of the American Uveitis Society, the International Uveitis Study Group, the Proctor Foundation mailing list server, and the First SUN International Workshop. Respondents were asked to provide clinical information about uveitis phenotype, AIH features, and treatment. RESULTS: Clinical information was obtained for seven individuals (four females and three males; age range, seven to 67 years) who suffered from AIH and uveitis. Average duration of follow-up was 5.5 years. All patients had chronic, persistent bilateral uveitis that was anterior (n = 3), intermediate (n = 1), or pan (n = 3) in location. Every patient had complications arising from his or her uveitis, including cataract (n = 5), glaucoma (n = 3), cystoid macular edema (n = 3), and posterior synechiae (n = 3). Final visual acuities ranged from 20/16 to hand movements. To treat the uveitis and/or AIH, the majority of patients required oral prednisone and all seven patients were treated with systemic immunosuppression. CONCLUSION: Despite the small size of this study, our findings suggest an association between AIH and uveitis. The uveitis is chronic, bilateral, and associated with sight-threatening complications, necessitating systemic immunosuppression in some individuals.

RESUMEN

PURPOSE: To describe host characteristics (use of highly active antiretroviral therapy [HAART]; CD4+ T-lymphocyte count; HIV ribonucleic acid [RNA] blood level) of people who were diagnosed with AIDS-related cytomegalovirus (CMV) retinitis after HAART became available and to investigate effects of HAART on ophthalmic findings. DESIGN: Retrospective, observational case series. METHODS: We collected demographic, medical, laboratory, and ophthalmic data for all patients with AIDS and newly diagnosed, untreated CMV retinitis from January 1997 through December 2000 at 10 sites in Los Angeles and Orange Counties, California. RESULTS: The proportions of Hispanic and African-American patients were equivalent to or greater than their prevalences in the AIDS and general populations of Los Angeles County. Most patients (n = 80; 63.5%) were known to be receiving HAART at the time of CMV retinitis diagnosis; only 22 patients (17.5%) were HAART-naïve. Median CD4+ T-lymphocyte count was 15 cells/microl and median HIV RNA blood level was 103,000 copies/ml for all patients, but in 10 patients, CMV retinitis developed despite good immunologic and virologic responses to HAART. When compared with HAART-naïve patients, HAART-failure patients with CMV retinitis had more asymptomatic disease (P = .073), better visual acuity in the better eye (P = .003), more bilateral disease (P = .007), less zone 1 involvement (P = .042), and lower lesion border opacity scores (P = .054). CONCLUSIONS: Most patients with AIDS and newly diagnosed CMV retinitis in an urban setting are HAART-experienced. HAART may influence characteristics of new CMV retinitis lesions at presentation, despite laboratory evidence of treatment failure, possibly because of residual CMV-specific immunity.
