RESUMO

BACKGROUND: Multiple health problems have been reported in survivors of Ebola virus disease (EVD). Attribution of these problems to the disease without a control group for analysis is difficult. METHODS: We enrolled a cohort of EVD survivors and their close contacts and prospectively collected data on symptoms, physical examination findings, and laboratory results. A subset of participants underwent ophthalmologic examinations. Persistence of Ebola virus (EBOV) RNA in semen samples from survivors was determined. RESULTS: A total of 966 EBOV antibody-positive survivors and 2350 antibody-negative close contacts (controls) were enrolled, and 90% of these participants were followed for 12 months. At enrollment (median time to baseline visit, 358 days after symptom onset), six symptoms were reported significantly more often among survivors than among controls: urinary frequency (14.7% vs. 3.4%), headache (47.6% vs. 35.6%), fatigue (18.4% vs. 6.3%), muscle pain (23.1% vs. 10.1%), memory loss (29.2% vs. 4.8%), and joint pain (47.5% vs. 17.5%). On examination, more survivors than controls had abnormal abdominal, chest, neurologic, and musculoskeletal findings and uveitis. Other than uveitis (prevalence at enrollment, 26.4% vs. 12.1%; at year 1, 33.3% vs. 15.4%), the prevalence of these conditions declined during follow-up in both groups. The incidence of most symptoms, neurologic findings, and uveitis was greater among survivors than among controls. EBOV RNA was detected in semen samples from 30% of the survivors tested, with a maximum time from illness to detection of 40 months. CONCLUSIONS: A relatively high burden of symptoms was seen in all participants, but certain symptoms and examination findings were more common among survivors. With the exception of uveitis, these conditions declined in prevalence during follow-up in both groups. Viral RNA in semen persisted for a maximum of 40 months.

RESUMO

Ocular chronic graft-versus-host disease is one of the most bothersome common complications following allogeneic hematopoietic stem cell transplantation. The National Institutes of Health Chronic Graft-versus-Host Disease Consensus Project provided expert recommendations for diagnosis and organ severity scoring. However, ocular chronic graft-versus-host disease can be diagnosed only after examination by an ophthalmologist. There are no currently accepted definitions of ocular chronic graft-versus-host disease activity. The goal of this study was to identify predictive models of diagnosis and activity for use in clinical transplant practice. A total of 210 patients with moderate or severe chronic graft-versus-host disease were enrolled in a prospective, cross-sectional, observational study (clinicaltrials.gov identifier: 00092235). Experienced ophthalmologists determined presence of ocular chronic graft-versus-host disease, diagnosis and activity. Measures gathered by the transplant clinician included Schirmer's tear test and National Institutes of Health 0-3 Eye Score. Patient-reported outcome measures were the ocular subscale of the Lee Chronic Graft-versus-Host Disease Symptom Scale and Chief Eye Symptom Intensity Score. Altogether, 157 (75%) patients were diagnosed with ocular chronic graft-versus-host disease; 133 of 157 patients (85%) had active disease. In a multivariable model, the National Institutes of Health Eye Score (P<0.0001) and Schirmer's tear test (P<0.0001) were independent predictors of ocular chronic graft-versus-host disease (sensitivity 93.0%, specificity 92.2%). The Lee ocular subscale was the strongest predictor of active ocular chronic graft-versus-host disease (P<0.0001) (sensitivity 68.5%, specificity 82.6%). Ophthalmology specialist measures that were most strongly predictive of diagnosis in a multivariate model were Oxford grand total staining (P<0.0001) and meibomian score (P=0.027). These results support the use of selected transplant clinician- and patient-reported outcome measures for ocular chronic graft-versus-host disease screening when providing care to allogeneic hematopoietic stem cell transplantation survivors with moderate to severe chronic graft-versus-host disease. Prospective studies are needed to determine if the Lee ocular subscale demonstrates adequate responsiveness as a disease activity outcome measure.

RESUMO

PURPOSE: Chronic granulomatous disease (CGD) is an inherited disorder characterized by defects in phagocyte-derived nicotinamide adenine dinucleotide phosphate oxidase. It is typically diagnosed in childhood and leads to severe, recurrent bacterial or fungal infections. Chorioretinal lesions are the most common ocular manifestation. We sought to determine whether there are infectious agents in CGD-associated chorioretinopathy. METHODS: Medical records and ocular histopathology from CGD cases from January 1983 to January 2012 at the National Institutes of Health were retrospectively reviewed. Chorioretinal cells from normal and lesional tissues of the same eye were microdissected. Primers for Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, Burkholderia sp., and a panbacterial 16S ribosomal DNA were used for polymerase chain reaction. RESULTS: Seventeen CGD patients had ocular tissues (16 autopsied cases and 1 chorioretinal biopsy) examined. Of these 17, 8 demonstrated CGD-associated chorioretinal lesions in at least one eye on histopathology. Of these 8, 7 showed amplification of 16S ribosomal DNA within the lesion; of these 7, two also amplified S. epidermidis and one P. aeruginosa. One had no bacterial DNA amplified. Importantly, no microbial DNA was amplified from the normal, non-lesional ocular tissues of these 8 cases. Furthermore, only 1 of the 9 eyes without chorioretinopathy had amplified Burkholderia DNA, that patient had a history of Burkholderia infection. CONCLUSIONS: We detected bacterial DNA in 7 of 8 (88%) cases with CGD-associated chorioretinopathy and only in 1 normal ocular tissue of 17 CGD cases. Bacterial infection may play a role in the pathogenesis of CGD-associated chorioretinal lesions.

RESUMO

OBJECTIVE: Xeroderma pigmentosum (XP) is a rare autosomal recessive disease caused by mutations in DNA repair genes. Clinical manifestations of XP include mild to extreme sensitivity to ultraviolet radiation resulting in inflammation and neoplasia in sun-exposed areas of the skin, mucous membranes, and ocular surfaces. This report describes the ocular manifestations of XP in patients systematically evaluated in the Clinical Center at the National Institutes of Health. DESIGN: Retrospective observational case series. PARTICIPANTS: Eighty-seven participants, aged 1.3 to 63.4 years, referred to the National Eye Institute (NEI) for examination from 1964 to 2011. Eighty-three patients had XP, 3 patients had XP/Cockayne syndrome complex, and 1 patient had XP/trichothiodystrophy complex. METHODS: Complete age- and developmental stage-appropriate ophthalmic examination. MAIN OUTCOME MEASURES: Visual acuity; eyelid, ocular surface, and lens pathology; tear film and tear production measures; and cytologic analysis of conjunctival surface swabs. RESULTS: Of the 87 patients, 91% had at least 1 ocular abnormality. The most common abnormalities were conjunctivitis (51%), corneal neovascularization (44%), dry eye (38%), corneal scarring (26%), ectropion (25%), blepharitis (23%), conjunctival melanosis (20%), and cataracts (14%). Thirteen percent of patients had some degree of visual axis impingement, and 5% of patients had no light perception in 1 or both eyes. Ocular surface cancer or a history of ocular surface cancer was present in 10% of patients. Patients with an acute sunburning skin phenotype were less likely to develop conjunctival melanosis and ectropion but more likely to develop neoplastic ocular surface lesions than nonburning patients. Some patients also showed signs of limbal stem cell deficiency. CONCLUSIONS: Our longitudinal study reports the ocular status of the largest group of patients with XP systematically examined at 1 facility over an extended period of time. Structural eyelid abnormalities, neoplasms of the ocular surface and eyelids, tear film and tear production abnormalities, ocular surface disease and inflammation, and corneal abnormalities were present in this population. Burning and nonburning patients with XP exhibit different rates of important ophthalmologic findings, including neoplasia. In addition, ophthalmic characteristics can help refine diagnoses in the case of XP complex phenotypes. DNA repair plays a major role in protection of the eye from sunlight-induced damage.

RESUMO

PURPOSE: Survivors of Ebola virus disease (EVD) are at risk for ocular complications after infection. We sought to identify demographic factors associated with the likelihood to present for eye examination among Ebola survivors enrolled in a longitudinal natural history study of EVD. METHODS: The Partnership for Research on Vaccines and Infectious Diseases in Liberia (PREVAIL) III Ebola natural history study is a 5-year study that seeks to identify long-term sequelae of EVD, including ocular sequelae. All survivors enrolled in the PREVAIL parent study from June 2015 to March 2016 were asked to return for comprehensive eye examination through June 2016. Logistic regression was conducted using self-reported survivor status, age, gender, and distance from the hospital as covariates. RESULTS: A total of 1448 subjects enrolled in the parent PREVAIL III longitudinal cohort during the defined window, of which 1375 (95.0%) followed up for baseline eye examination. Ebola survivors (635/661, 96.1%) and adult close contacts (727/767, 94.8%) demonstrated a comparable likelihood for presenting for eye examination (odds ratio [OR] 0.68, 95% confidence interval [CI] 0.36-1.28). In an adjusted model, age over 50 (OR 10.2, 95% CI 1.35-77.3) and living outside Montserrado County (OR 0.18, 95% CI 0.10-0.33) were associated with the likelihood of presenting for a baseline comprehensive eye examination. CONCLUSION: Most EVD survivors and their close contacts who enrolled during the study window presented for eye examinations. Older participants and those who lived closer to clinical facilities were most likely to present. Focused strategies accounting for these factors may assist with organizations planning survivor care in the setting of EVD.

RESUMO

Objective: Survivors of Ebola virus disease (EVD) experience decreased intraocular pressure (IOP) relative to unaffected close contacts during the first year of convalescence. Whether this effect persists over time and its relationship to intraocular pathology are unclear. We sought to determine whether IOP remained lower in survivors of EVD over 4 years of follow-up and to identify associated risk factors. Design: Partnership for Research on Vaccines and Infectious Diseases in Liberia (PREVAIL) III is a 5-year, longitudinal cohort study of survivors of EVD and their close contacts and is a collaboration between the Liberian Ministry of Health and the United States National Institutes of Health. Participants: Participants who enrolled in PREVAIL III at John F. Kennedy Medical Center in Liberia, West Africa from June 2015 to March 2016 who underwent comprehensive ophthalmic evaluation annually for 5 consecutive visits. Methods: Intraocular pressure was measured at each visit by a handheld rebound tonometer using sterile tips. Comparisons are made between antibody-positive survivors and antibody-negative close contacts. Main Outcome Measures: Intraocular pressure, measured in mmHg, at each study visit. Results: Of 565 antibody-positive survivors and 644 antibody-negative close contacts enrolled in the study at baseline, the majority of participants returned annually, with 383 (67.8%) and 407 (63.2%) participants, respectively, presenting for the final study visit at a median of 60 months after symptom onset. A sustained, relative decrease in IOP was observed in survivors relative to close contacts, with mean difference of -0.72 mmHg (95% confidence interval [CI] -1.18 to -0.27) at the final study visit. This difference remained constant throughout the study period (P = 0.4 for interaction over time). Among survivors, physical examination findings of vitreous cell and OCT findings of vitreous opacities both demonstrated a significant association with decreased IOP at baseline (P < 0.05 for both). After adjusting for such factors, the difference throughout the follow-up (-0.93 mmHg, 95% CI, -1.23 to -0.63) remained significant. Conclusions: Survivors of EVD experienced a sustained decrease in IOP relative to close contacts over a 5-year period after EVD. The results highlight the importance of considering long-term sequelae of emerging infectious diseases within a population.

RESUMO

Gene therapy of human cancer using genetically engineered lymphocytes is dependent on the identification of highly reactive T-cell receptors (TCRs) with antitumor activity. We immunized transgenic mice and also conducted high-throughput screening of human lymphocytes to generate TCRs highly reactive to melanoma/melanocyte antigens. Genes encoding these TCRs were engineered into retroviral vectors and used to transduce autologous peripheral lymphocytes administered to 36 patients with metastatic melanoma. Transduced patient lymphocytes were CD45RA(-) and CD45RO(+) after ex vivo expansion. After infusion, the persisting cells displayed a CD45RA(+) and CD45RO(-) phenotype. Gene-engineered cells persisted at high levels in the blood of all patients 1 month after treatment, responding patients with higher ex vivo antitumor reactivity than nonresponders. Objective cancer regressions were seen in 30% and 19% of patients who received the human or mouse TCR, respectively. However, patients exhibited destruction of normal melanocytes in the skin, eye, and ear, and sometimes required local steroid administration to treat uveitis and hearing loss. Thus, T cells expressing highly reactive TCRs mediate cancer regression in humans and target rare cognate-antigen-containing cells throughout the body, a finding with important implications for the gene therapy of cancer. This trial was registered at www.ClinicalTrials.gov as NCI-07-C-0174 and NCI-07-C-0175.

RESUMO

This longitudinal cohort study compared ocular surface indicators in forty allogeneic hematopoietic stem cell transplant (HSCT) subjects with twenty healthy controls at baseline and identified changes in ocular graft-versus-host disease (oGVHD). Outcome measures included: Ocular Surface Disease Index (OSDI), tear osmolarity, Schirmer's test, Oxford corneal staining score, tear break-up time (TBUT), and tear and serum biomarkers (IFN-γ, IL-10, MMP-9, IL-12, IL-13, IL-17α, IL-1ß, IL-2, IL-4, IL-6, IL-8, CXCL10, MCP-1, MIP-1α, RANTES, TNF-α). At baseline the HSCT group had higher median Oxford corneal staining score (1.7 vs. 0.0; P < 0.0001), higher tear TNF-α (20.0 vs. 11.2 pg/mL; P < 0.0001), lower tear RANTES (70.4 vs. 190.2 pg/mL; P < 0.0001), higher serum IL-8 (10.2 vs. 4.5 pg/mL; P = 0.0008), and higher serum TNF-α (8.7 vs. 4.2 pg/mL; P < 0.0001). The incidence of oGVHD was 62% and associated changes included increased Oxford corneal staining score (4.6 vs. 1.8, P = 0.0001), decreased Schirmer's test (3.0 vs. 10.0; P < 0.0001), and decreased TBUT (4.7 vs. 9.0 s; P = 0.0004). Baseline differences in ocular surface indicators suggest a tendency toward ocular dryness in individuals with hematologic disorders preparing for HSCT. Individuals who developed oGVHD showed changes in corneal staining score, Schirmer's test, and TBUT.

RESUMO

Purpose: In survivors of Ebola virus disease (EVD), intraocular viral persistence raises questions about the timing and safety of cataract surgery. To the best of our knowledge, this is the first controlled study evaluating Ebola virus persistence and cataract surgery safety and outcomes in EVD survivors. Methods: Seropositive EVD survivors and seronegative controls with vision worse than 20/40 from cataract and without active intraocular inflammation were enrolled. Aqueous humor from survivors was tested with reverse transcription-polymerase chain reaction for Ebola viral RNA. Participants underwent manual small-incision cataract surgery and 1 year of follow-up examinations. Results: Twenty-two eyes of 22 survivors and 12 eyes of eight controls underwent cataract surgery. All of the aqueous samples tested negative for Ebola viral RNA. Median visual acuity improved from 20/200 at baseline to 20/25 at 1 year in survivors and from count fingers to 20/50 in controls (overall, P < 0.001; between groups, P = 0.07). After a 1-month course of topical corticosteroids, 55% of survivors and 67% of controls demonstrated at least 1+ anterior chamber cell. Twelve months after surgery, optical coherence tomography revealed a median increase in macular central subfield thickness of 42 µm compared with baseline (overall, P = 0.029; between groups, P = 0.995). Conclusions: EVD survivors and controls demonstrated significant visual improvement from cataract surgery. The persistence of intraocular inflammation highlights the importance of follow-up. The absence of detectable intraocular Ebola viral RNA provides guidance regarding the safety of eye surgery in Ebola survivors. Translational Relevance: These findings demonstrate the safety and efficacy of cataract surgery in Ebola survivors and will inform ocular surgery guidelines in this population.

RESUMO

Importance: Survivors of Ebola virus disease (EVD) may experience ocular sequelae. Comparison with antibody-negative individuals from the local population is required to characterize the disease. Objective: To assess features of ophthalmic disease specific to EVD. Design, Setting, and Participants: This baseline cross-sectional analysis of survivors of EVD and their close contacts was conducted within PREVAIL III, a 5-year, longitudinal cohort study. Participants who enrolled at John F. Kennedy Medical Center in Liberia, West Africa from June 2015 to March 2016 were included in this analysis. Close contacts were defined as household members or sex partners of survivors of EVD. Data were analyzed from July 2016 to July 2020. Exposures: All participants, both survivors and close contacts, underwent testing of IgG antibody levels against Ebola virus surface glycoprotein. Main Outcomes and Measures: Ocular symptoms, anterior and posterior ophthalmologic examination findings, and optical coherence tomography images were compared between antibody-positive survivors and antibody-negative close contacts. Results: A total of 564 antibody-positive survivors (320 [56.7%] female; mean [SD] age, 30.3 [14.0] years) and 635 antibody-negative close contacts (347 [54.6%] female; mean [SD] age, 25.8 [15.5] years) were enrolled in this study. Survivors were more likely to demonstrate color vision deficit (28.9% vs 19.0%, odds ratio [OR], 1.6; 95% CI, 1.2-2.1) and lower intraocular pressure (12.4 vs 13.5 mm Hg; mean difference, -1.2 mm Hg; 95% CI, -1.6 to -0.8 mm Hg) compared with close contacts. Dilated fundus examination revealed a higher percentage of vitreous cells (7.8% vs 0.5%; OR, 16.6; 95% CI, 5.0-55.2) and macular scars (4.6% vs 1.6%; OR, 2.8; 95% CI, 1.4-5.5) in survivors than in close contacts. Uveitis was present in 26.4% of survivors and 12.1% of close contacts (OR, 2.4; 95% CI, 1.8-3.2). Among all participants with uveitis, survivors were more likely than close contacts to have intermediate uveitis (34.2% vs 6.5% of all cases; OR, 7.8; 95% CI, 3.1-19.7) and had thicker mean central subfield thickness on optical coherence tomography (222 vs 212 µm; mean difference, 14.4 µm; 95% CI, 1.9-26.9 µm). Conclusions and Relevance: In this cross-sectional study, survivors of EVD had a distinct spectrum of ocular and neuro-ophthalmologic findings compared with close contacts that potentially require medical and surgical treatment.

RESUMO

Although xerostomia is a commonly reported complaint in patients with chronic graft-versus-host disease (cGVHD), criteria for evaluating the prevalence and characteristics of salivary gland involvement have not been well defined in this patient population. Previous studies also have made no distinction between salivary and mucosal oral cGVHD. We systematically evaluated signs and symptoms of sicca in a large cohort of patients with cGVHD (n = 101) using instruments widely used to study Sjogren's syndrome. Xerostomia was reported in 60 (77%) patients reporting ocular and 52 (67%) patients reporting oral complaints [corrected]. The salivary flow rate was < or =0.2 mL/min in 27%, and < or =0.1 mL/min in 16%. Histopathological changes, consisting of mononuclear infiltration and/or fibrosis/atrophy, were present in all patients with salivary dysfunction. Importantly, there was no correlation of salivary and oral mucosal involvement in cGVHD. Patients with cGVHD-associated salivary gland involvement had diminished oral cavity-specific quality of life and lower body mass index. Salivary gland involvement is a common and clinically distinct manifestation of cGVHD. Formal evaluation of salivary function using standardized criteria is needed, and this could be incorporated as an outcome measure in clinical trials of cGVHD.

RESUMO

PURPOSE: The purpose of this study was to report the clinical and pathologic findings of three cases of rapid vision loss associated with fludarabine toxicity. METHODS: A retrospective, single-center case series was conducted. Autopsies of the eyes from three cases were performed. RESULTS: A 23-year-old man (Case 1) with systemic lupus erythematosus developed rapid and severe vision loss, generalized neurologic decline, and eventual death after administration of fludarabine before stem cell transplantation. A 48-year-old woman (Case 2) and a 60-year-old man (Case 3), both with metastatic melanoma, had similar courses after receiving fludarabine as part of a preparatory regimen before adoptive cell therapy. Fundus examination showed punctuate yellow flecks in the macula after visual decline in two cases. In all three cases, serum antiretinal antibodies were negative before and after treatment; electrophysiological testing showed markedly decreased B-waves; and pathologic analysis showed loss of retinal bipolar and ganglion cells, gliosis within the retina and optic nerve, and optic nerve atrophy. CONCLUSION: Fludarabine toxicity can result in severe vision loss attributable to damage to retinal bipolar and ganglion cells. Although effective treatments are not known, care should be taken to consider fludarabine toxicity in patients who present with vision loss approximately 1 month after treatment.

RESUMO

OBJECTIVE: Human genome-wide association studies and animal models suggest a role for TGFB2 in contributing to the corneal thickness phenotype. No specific mutations, however, have been reported in this gene that affect corneal thickness. We sought to determine if haploinsufficiency of TGFB2 in humans associated with Loeys-Dietz syndrome type 4 is associated with corneal thinning. DESIGN: Observational cohort study of families with Loeys-Dietz syndrome type 4, caused specifically by TGFB2 mutations, in a tertiary care setting. PARTICIPANTS: Three probands with pathogenic mutations in TGFB2 and family members underwent comprehensive ophthalmic examination. METHODS: Clinical assessment included Scheimpflug imaging, specular microscopy, and slit-lamp biomicroscopy. We measured visual acuity, axial length, refractive error, and central corneal thickness. RESULTS: Clinical evaluation of 2 probands identified corneal thinning and cornea guttata, despite a young age and distinct mutations in TGFB2 (c.905G>A, p.Arg302His; c.988C>A, p.Arg330Ser). In the third family, corneal thinning co-segregated with a TGFB2 mutation (c.1103G>A, p.Gly368Glu), although without apparent guttae. CONCLUSIONS: In this series, participants with TGFB2 mutations associated with Loeys-Dietz syndrome type 4 demonstrated decreased corneal thickness, and in 2 cases with splice site mutations, also demonstrated cornea guttata. The data demonstrate the importance of considering distinct phenotype-genotype correlations within this condition.

RESUMO

OBJECTIVE: To describe the ophthalmic and systemic autoimmune findings after successful adoptive cell transfer of ex vivo expanded, autologous tumor-reactive tumor-infiltrating lymphocytes (TIL) for metastatic melanoma. DESIGN: Retrospective, interventional case report. PARTICIPANT: A 35-year-old man who underwent immunotherapy for metastatic melanoma with adoptive cell transfer of tumor-reactive TIL. METHODS: A 35-year-old man with metastatic melanoma was treated with TIL plus interleukin-2 (IL-2) therapy after a lymphodepleting regimen of cyclophosphamide and fludarabine for metastatic melanoma, which led to a complete and durable remission. Bilateral panuveitis, hearing loss, vitiligo, poliosis, and alopecia developed in the patient, requiring local ophthalmic immunosuppressive therapy. The clinical course, diagnostic testing, and therapeutic interventions over a 2-year period are reviewed. MAIN OUTCOME MEASURES: Visual acuity, anterior chamber and vitreous inflammation, optical coherence tomography findings, serial electro-oculograms (EOGs), microperimetry (MP-1) testing, flow cytometric analysis of cells derived from the aqueous humor, and aqueous humor cytokine profiles were evaluated. RESULTS: After melanoma immunotherapy, complete tumor regression was achieved at 5 months after treatment with a durable, ongoing, complete remission at 24 months. Early in the treatment course, a high fever, a diffuse rash, hearing loss, and bilateral anterior uveitis developed acutely in the patient. Late autoimmune sequelae included the development of alopecia, vitiligo, poliosis, and bilateral panuveitis with diffuse retinal pigment epithelium (RPE) hypopigmentation, reminiscent of Vogt-Koyanagi-Harada (VKH) syndrome. Bilateral cystoid macular edema also developed that was responsive to acetazolamide. Serial EOGs showed alterations in RPE standing potentials in dark conditions, and MP-1 testing revealed diminished foveal and perifoveal sensitivity. An aqueous humor aspirate revealed a high concentration of melanoma tumor antigen-reactive T cells compared with that of peripheral blood samples, as well as a proinflammatory aqueous cytokine profile. At the time of cataract surgery 22 months after immunotherapy, a repeat aqueous humor sample showed the disappearance of the previously seen melanoma differentiation antigen-reactive lymphocytes, but the proinflammatory cytokine profile persisted. CONCLUSIONS: Ocular and systemic autoimmune sequelae resembling VKH may develop after successful melanoma immunotherapy. This report provides insight into the pathogenesis of VKH disease. The patient's clinical course illustrates the fine balance between tumor-specific immunity and loss of self-tolerance.
