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 determine the features of primary vitreoretinal lymphoma on multimodal ultra-widefield imaging and correlate these findings to clinical outcomes. METHODS: We report a retrospective, observational case series of 43 eyes of 23 patients with biopsy-proven B-cell primary vitreoretinal lymphoma. Fundus photography, fluorescein angiography (FA), optical coherence tomography, fundus autofluorescence, and indocyanine green angiography images were reviewed. Medical records were assessed for the central nervous system involvement and visual acuity outcomes at 6 and 12 months after presentation. RESULTS: Common fundus photography findings were sub-retinal pigment epithelium lesions and vitritis alone. Common ultra-widefield FA findings were vascular leakage and scleral staining. Retinal optical coherence tomography features overlying sub-retinal pigment epithelium lesions or within the macula predicted fluorescence patterns. The presence of retinal fluid or disorganization associated with hyperfluorescence and late leakage. Normal retinal structures associated with hypofluorescence of sub-retinal pigment epithelium lesions or macular leopard spotting on FA and fundus autofluorescence. Peripheral abnormalities noted on ultra-widefield fundus photography, FA, and indocyanine green angiography were more frequent than posterior pole abnormalities. No imaging characteristics predicted time to the central nervous system progression. CONCLUSION: Ultra-widefield imaging was more informative than posterior pole imaging in fundus photography, FA, and indocyanine green angiography. Common findings on multimodal ultra-widefield imaging may lead to early diagnostic vitrectomy and may reduce the delay in primary vitreoretinal lymphoma diagnosis.

RESUMEN

PURPOSE: To report a case of herpes zoster keratitis in a patient undergoing treatment for herpetic acute retinal necrosis. METHODS: Case report. RESULTS: A 71 year old male presented with acute retinal necrosis of the left eye due to herpes zoster and was treated with intravitreal foscarnet and oral valcyclovir. He developed a retinal detachment and underwent surgical repair. After four weeks, he developed an ipsilateral herpetic zoster keratitis demonstrated by Rose-Bengal staining that was responsive to topical ganciclovir gel. CONCLUSIONS: This case report describes the unusual development of herpes zoster keratitis after the development of unilateral acute retinal necrosis (ARN) in a patient on antiviral treatment.

RESUMEN

PURPOSE: To examine cases of intermediate uveitis complicated by retinoschisis and review the pathogenetic hypothesis. METHODS: A retrospective chart review of patients with intermediate uveitis. Data were collected at three uveitis referral centers on sex, age, best-corrected visual acuity, degree of vitritis, extent and location of snowbanking, presence of hard exudates, neovascularization, vitreous hemorrhage, and extent and nature of retinal elevations. RESULTS: A series of 23 eyes of 20 patients were examined; patient's age ranged from 10 years to 70 years and follow-up period from 8 months to 6 years. Twenty-two eyes had retinoschisis (95.6%), and 1 had retinoschisis associated with serous retinal detachment (4.3%). Extensive inferior pars plana exudates with snowbanking were present in 12 eyes (52.2%), whereas 3 eyes had inferior snowballs over the elevated retina. Neovascularization of the vitreous base accompanied by vitreous hemorrhage occurred in one eye. There was no coexisting macular pathology in 16 eyes, whereas 4 eyes had cystoid macular edema. CONCLUSION: The appearance of peripheral retinoschisis in this series of uncontrolled intermediate uveitis patients seems to be secondary to a complex balance between the persistent fluorescein leakage, a subclinical peripheral ischemia, and the constant low-grade vitreous inflammation that causes vitreous shrinkage and traction. The results of this study suggest that the absence of macroscopic changes in the retina does not preclude ischemic peripheral abnormalities, and the detection of a peripheral retinoschisis in an intermediate uveitis patient with active fluorescein leakage must suggest the need for a more aggressive form of treatment despite the good visual acuity.

RESUMEN

PURPOSE: To evaluate the short-term safety and efficacy of topical difluprednate (0.05%) for the treatment of noninfectious uveitic cystoid macular edema. METHODS: Twenty-seven patients (35 eyes) undergoing treatment with difluprednate 4 times daily for 3 weeks for noninfectious uveitic cystoid macular edema were reviewed for visual acuity, intraocular pressure, optical coherence tomography, and fluorescein angiography results. A mixed model analysis was fit with each measure as the outcome, visit as the primary predictor, and patient and eye as random effects. RESULTS: Mean central foveal thickness decreased by 117 µm (P < 0.001) at 30 ± 15 days, 124 µm (P < 0.001) at 60 ± 15 days, and 152 µm (P < 0.001) at 180 ± 30 days. Complete resolution of intraretinal fluid was observed in 15 of 34 (44%) eyes at 30 ± 15 days, 11 of 21 (52%) eyes at 60 ± 15 days, and 9 of 12 (75%) eyes at 180 ± 30 days. Improvement in fluorescein leakage was noted in 7 of 8 eyes (88%). Visual acuity improved by a mean of 5 letters (P = 0.001) at 30 ± 15 days, 5.5 letters (P = 0.007) at 60 ± 15 days, and 7 letters (P = 0.032) at 180 ± 30 days. Mean increase in intraocular pressure was 1.48 mmHg at 30 ± 15 days (P = 0.080), 1.92 mmHg at 60 ± 15 days (P = 0.110), and 6.18 mmHg (P = 0.001) at 180 ± 30 days. CONCLUSION: Topical difluprednate is a well-tolerated and effective treatment for noninfectious uveitic cystoid macular edema with decreased central foveal thickness, mild improvement in visual acuity, and elevation of intraocular pressure observed in a few patients.

RESUMEN

The purpose of this study is to review the results of treatment of juvenile idiopathic arthritis-related uveitis with the use of intravitreal dexamethasone implant. Sixteen eyes with Juvenile idiopathic arthritis (JIA)-associated uveitis received intravitreal dexamethasone implant to treat recalcitrant anterior segment inflammation (43.7 %), chronic macular edema (6.2 %), or a combination of both (50 %). One month after injection, mean visual acuity had improvement to 39.6 ± 11 ETDRS letters (p < 0.001). Mean AC cells measure at 1 month was 0.79 and 0.75 at 3 months. One month after injection, there was a significant reduction of central retinal thickness (CRT) to 342.4 ± 79.3 µm (p < 0.01). One month after the second implant, 11 eyes (91.6 %) achieved improved activity of the anterior uveitis, and mean best-corrected visual acuity improved to 44.6 ± 8.1 ETDRS letters (p < 0.01). At 1 month after the second injection, 4/5 eyes had resolution of macular edema with CRT of 250.4 ± 13.7 µm (p < 0.01). Of the 16 eyes, 12 eyes received a second injection at mean of 7.5 ± 3.1 months after the first treatment, and 5 eyes received a third Ozurdex injection on average 7 ± 4.6 months after the second injection. Of the 16 eyes, five eyes were pseudophakic prior to injection. Of the remaining 11 eyes, 8 (73 %) developed worsening posterior subcapsular cataract at a mean of 7.3 ± 1.2 months after the first injection. After the first injection, only one eye required topical antiglaucoma therapy with maximum pressure of 25 mmHg. In patients with recalcitrant JIA-associated active uveitis, injection of sustained-release dexamethasone can achieve control of anterior inflammation and resolution of macular edema.

RESUMEN

PURPOSE: To localize the various levels of abnormalities in multiple evanescent white dot syndrome by comparing "en face" optical coherence tomography (OCT) and OCT angiography with various conventional imaging modalities. METHODS: In this retrospective case series, multimodal imaging was performed in 9 retinal centers on 36 patients with multiple evanescent white dot syndrome and included widefield fundus autofluorescence (FAF), fluorescein angiography (FA), and indocyanine green angiography, and B-scan and "en face" C-scan enhanced depth imaging and spectral domain OCT. Optical coherence tomography angiography was also performed at the level of the superficial and deep retinal capillary plexus and choroid. RESULTS: Multiple evanescent white dot syndrome lesions were more numerous and more easily detectable with FA and FAF. Two types of lesions were identified with FAF, FA, and indocyanine green angiography: larger widely scattered "spots" (approximately 200 µ in diameter) that were hyperfluorescent with FA, hyperautofluorescent with FAF, and hyporeflective in indocyanine green angiography, representing abnormalities primarily at the retinal pigment epithelium/photoreceptor junction; and punctate "dots" (less than 100 µ in diameter) that were hyperfluorescent with FA, hyperautofluorescent, or isoautofluorescent with FAF, and hypofluorescent with indocyanine green angiography and that localized to the outer nuclear layer. These lesions colocalized with "en face" OCT. The larger confluent "spots" were hyporeflective and colocalized to the level of the ellipsoid zone, whereas smaller hyperreflective "dots" colocalized to the outer nuclear layer. The location of the "dots" in the outer nuclear layer was further confirmed by structural spectral domain optical coherence tomography which showed coalescence of the dots into hyperreflective lines extending from the external limiting membrane to the outer plexiform layer in certain cases. Optical coherence tomography angiography analysis of the retinal microvasculature and choriocapillaris and choroid were entirely unremarkable in 100% of our patients. CONCLUSION: By combining multimodal imaging, the authors propose that multiple evanescent white dot syndrome is primarily the result of inflammation at the outer photoreceptor level leading to a "photoreceptoritis" and causing loss of the inner and outer segments. Its evanescent nature suggests that the photoreceptor cell bodies remain intact ensuring complete recovery of the photoreceptor inner and outer segments in most cases, compatible with the clinical course of spontaneous resolution of white spots and dots.

RESUMEN

The purpose of the study was to describe the findings seen on anterior segment spectral domain optical coherence tomography (SD-OCT) in patients with anterior scleritis and determine the feasibility of using SD-OCT to image and grade the degree of scleral inflammation and monitor response to treatment. All patients underwent slit lamp examination by a uveitis specialist, and the degree of scleral inflammation was recorded. Spectral domain OCT imaging was then performed of the conjunctiva and scleral tissue using a standardized acquisition protocol. The scans were graded and compared to clinical findings. Twenty-eight patients with anterior scleritis and ten patients without ocular disease were included in the study. Seventeen of the scleritis patients were followed longitudinally. Common findings on SD-OCT in patients with active scleritis included changes in hyporeflectivity within the sclera, nodules, and visible vessels within the sclera. There was significant variation in findings on SD-OCT within each clinical grade of active scleritis. These changes on SD-OCT improved with treatment and clinical improvement. SD-OCT imaging provided various objective measures that could be used in the future to grade inflammatory activity in patients with anterior scleritis. Longitudinal imaging of patients with active scleritis demonstrated that SD-OCT may have great utility in monitoring response to treatment.

RESUMEN

Immune-mediated uveitis may be associated with a systemic disease or may be localized to the eye. T-cell-dependent immunological events are increasingly being regarded as extremely important in the pathogenesis of uveitis. Several studies have also shown that macrophages are major effectors of tissue damage in uveitis. Uveitis phenotypes can differ substantially, and most uveitis diseases are considered polygenic with complex inheritance patterns. This review attempts to present the current state of knowledge from in vitro and in vivo research on the role of genetics in the development and clinical course of uveitis. A review of the literature in the PubMed, MEDLINE, and Cochrane databases was conducted to identify clinical trials, comparative studies, case series, and case reports describing host genetic factors as well as immune imbalance which contribute to the development of uveitis. The search was limited to primary reports published in English with human subjects from 1990 to the present, yielding 3590 manuscripts. In addition, referenced articles from the initial searches were hand searched to identify additional relevant reports. After title and abstract selection, duplicate elimination, and manual search, 55 papers were selected for analysis and reviewed by the authors for inclusion in this review. Studies have demonstrated associations between various genetic factors and the development and clinical course of intraocular inflammatory conditions. Genes involved included genes expressing interleukins, chemokines, chemokine receptors, and tumor necrosis factor and genes involved in complement system. When considering the genetics of uveitis, common threads can be identified. Genome-wide scans and other genetic methods are becoming increasingly successful in identifying genetic loci and candidate genes in many inflammatory disorders that have a uveitic component. It will be important to test these findings as uveitis-specific genetic factors. Therefore, the burgeoning understanding of the human genome promises to result in new insight into the pathogenesis of uveitis.

RESUMEN

PURPOSE: This study was designed to determine the feasibility of anterior segment optical coherence tomography (AS-OCT) to objectively image and quantify the degree of AC inflammation. DESIGN: Prospective evaluation of a diagnostic test. PARTICIPANTS: Patients with anterior segment involving uveitis. METHODS: Observational case series of patients with uveitis. Single-line and 3-dimensional (3D) volume AS-OCT scans were manually graded to evaluate for the presence or absence of cells in the AC. Clinical grading scores were correlated to the number of cells seen in each line scan. An automated algorithm was developed to measure the number of cells seen in the 3D volume scan and compared with manual measurements and clinical grading scores. MAIN OUTCOME MEASURES: Degree of anterior segment inflammation. RESULTS: A total of 114 eyes from 76 patients were imaged, 83 eyes with line scans and 31 eyes with volume scans. The average number of cells on line scans was 0.13 for grade 0, 1.2 for grade 1/2+, 2.6 for grade 1+, 5.7 for grade 2+, 15.5 for grade 3+, and 41.2 for grade 4+. Spearman correlation coefficient comparing clinical grade with the individual AS-OCT line scans was 0.967 (P < 0.0001). The range of cells in the automated cell count of 3D volume scans was 13.60 to 1222; the range for manual cell counts was from 9.2 to 2245. The Spearman correlation coefficients were r = 0.7765 (P < 0.0001) and r = 0.7484 (P < 0.0001) comparing the manual and automated cell counts with the clinical grade, respectively. Spearman correlation coefficient comparing the automatic cell counts with manual cell count in the 3D volume scan was 0.997 (P < 0.0001). CONCLUSIONS: Anterior segment OCT can be used to image and grade the degree of AC inflammation. Clinical grading strongly correlates with the number of cells on AS-OCT line scans and volume scans. The automated algorithm to measure cell count had a high correlation to manual measurement of cells in the 3D volume scans. This modality could be used to objectively grade response to treatment.

RESUMEN

Signs of malnutrition are common clinical features in Crohn's disease; and bowel resection, commonly needed in these cases, can aggravate malnutrition. These patients are at risk of developing vitamin A deficiency, which can lead to night blindness. We present a 60-year-old male, with history of Crohn's disease and multiple resections for strictures and fistulas leading to short bowel syndrome, with progressive bilateral loss of night vision (nyctalopia). Serum vitamin A level was markedly depleted (11 µg/dL, reference 20-120 µg/dL), and full-field electroretinogram testing demonstrated extinguished scotopic (rod function) responses and decreased amplitudes of photopic responses on 30 Hz flicker (cone function). He was started on vitamin A supplementation (initially intramuscular). His vitamin A level was back to normal (78 µg/dL), and night vision problems subjectively improved. Patients with Crohn's disease should be inquired about night vision problems. The presence of nyctalopia should prompt vitamin A level measurement and ophthalmology referral for further evaluation.

RESUMEN

To report two cases of acute and chronic-onset, postoperative Staphylococcus epidermidis endophthalmitis and discuss the virulence and treatment of this saprophytic pathogen. After clinical diagnosis of endophthalmitis, prompt vitreous culture was performed with injection of intravitreal vancomycin 1 mg/0.1 mL and ceftazidime 2.25 mg/0.1 mL. With no improvement after this procedure, a pars plana vitrectomy and lensectomy were performed to further decrease microbial load and repeat the intravitreal antibiotic. The lens and large amounts of fibrotic tissue were removed, and the posterior capsule was stripped. Vitreous cultures grew S. epidermidis sensitive to vancomycin. Intraoperative findings included dense vitreous opacification with extensive vitreous bands and pus extending into the zonules. During the removal of the IOL, adherent pus filaments were removed; however, only a moderate amount of bacteria was detected on the IOL. Further intravitreal vancomycin (1 mg/0.1 mL) and ceftazidime (2.25 mg/0.1 mL) were injected. Staphylococcus epidermidis is widely reported as responsible for medical device-related sepsis. This is mainly due to the production of slime, an exopolysaccharide that eventually leads to the formation of biofilm, one of the most important virulence factors. The failure of intravitreal antibiotic treatment in our two biofilm-associated infections may be due to the considerable amount of slime and pus found extending into the zonules and adherent to the IOL during surgery.

RESUMEN

PURPOSE: To analyze the early spectral domain optical coherence tomography changes after fluocinolone implantation in eyes with baseline uveitic macular edema. METHODS: Patients with uveitic macular edema and who received fluocinolone implantations by 2 surgeons (R.P.S. and J.E.S.) at the Cole Eye Institute (Cleveland Clinic, Cleveland, OH) from September 2009 to July 2010 were eligible for this study. Best-corrected visual acuity, intraocular pressure, central subfield thickness, cube volume, cube average thickness, and cystoid macular edema grade were recorded before implantation and in the early postoperative period (median: 3 months postimplantation). Changes in these variables were analyzed using the Wilcoxon signed-rank test for paired comparisons of clustered data. P values were 2 sided, and alpha was set at 0.05. RESULTS: Twelve eyes of seven patients were included in the study. The median best-corrected visual acuity improved in the early postoperative period after implantation (20/80 before implantation and 20/50 after implantation), but this improvement was not found to be significant (P = 0.12). However, the spectral domain optical coherence tomography measurements-central subfield thickness, cube volume, cube average thickness, and cystoid macular edema grade-were all significantly reduced (median changes: -234 µm [P = 0.02], -1 mm [P = 0.04], -39 µm [P = 0.04], and -3 [P = 0.03], respectively). CONCLUSION: Fluocinolone implantation is associated with a significant reduction in macular edema as measured by spectral domain optical coherence tomography in the early postoperative period, a result that is consistent with the proposed mechanism of the drug.

RESUMEN

BACKGROUND AND OBJECTIVE: Bacillary layer detachment (BALAD) is a recently described finding on optical coherence tomography (OCT) that has been reported in a variety of uveitic and retinal diseases. To add to the growing literature on conditions associated with this finding, we report on the first cases of BALADs in ocular sarcoidosis. PATIENTS AND METHODS: Observational, retrospective chart review of patients with BALADs as a feature of sarcoid-associated uveitis. RESULTS: Three patients presented with blurry vision and bacillary layer detachments on OCT who were either known to have or found to have sarcoid-associated uveitis. All three patients had resolution of the BALAD and improvement in visual acuity with a combination of high-dose oral steroids and/or systemic immunosuppression. CONCLUSIONS: Patients presenting with BALAD should be assessed for sarcoidosis, if appropriate, given the systemic implications of this diagnosis.

RESUMEN

Purpose: Ocular syphilis can present as a wide variety of clinical phenotypes, among them panuveitis with vasculitis. Primary retinal phlebitis with resulting paravenous atrophy and pigmentary retinal degeneration is a rare presentation. Methods: A 53-year-old man presented with a 1-year history of bilateral blurry vision. Physical examination demonstrated bilateral anterior chamber and vitreous cell with vitreous haze, hyperemic optic nerves, and atrophic-appearing retina. The left eye demonstrated a nasal area of perivenular vascular sheathing with adjacent retinal whitening. Ancillary testing demonstrated predominantly perivenular leakage involvement. Results: Uveitic workup was positive for syphilis and HIV. The patient was treated with antiretroviral therapy and intravenous penicillin G. He developed progressive paravenous pigmentary changes and atrophy. Conclusions: Syphilis can present with a wide variety of phenotypic manifestations and should also be considered in patients presenting with acute retinal phlebitis or paravenous atrophy in long-standing cases.

RESUMEN

Purpose: This work aims to present treatment and long-term follow-up of a 31-year-old woman with dermatomyositis who presented with hemorrhagic retinal vasculitis and macular edema. Methods: A retrospective case report is presented. Results: A 31-year-old woman with dermatomyositis treated with systemic immunosuppression was evaluated for acute, reduced vision. Best-corrected visual acuity was hand motion in the right eye and 20/200 in the left eye. Fundus examination revealed diffuse intraretinal hemorrhages, cotton-wool spots, and vascular sheathing with a frosted branch angiitis-like appearance. Optical coherence tomography revealed significant macular edema and subretinal fluid that quickly resolved after admission and treatment with intravenous steroids. Multimodal imaging at 7-year follow-up disclosed long-term sequelae including peripheral nonperfusion and retinal neovascularization. Conclusions: When vasculitis associated with dermatomyositis is treated aggressively with intravenous steroids at initial presentation, good visual acuity outcomes can be achieved, but long-term consequences of retinal nonperfusion and neovascularization persist.

RESUMEN

PURPOSE: Chronic postoperative endophthalmitis is a known complication of cataract surgery. Here, we report a case of chronic endophthalmitis following uncomplicated cataract surgery secondary to the atypical bacterium Aquamicrobium terrae . METHODS: Retrospective case report of a single patient with endophthalmitis secondary to A. terrae. RESULTS: A 61-year-old healthy patient presented with recurrent iridocyclitis following uncomplicated cataract surgery. Repeated attempts to taper off topical steroid eyedrops were unsuccessful. Anterior chamber paracentesis cultures and vitrectomy cultures grew the same gram-negative bacillus, A. terrae , on six different occasions. The patient was treated initially with a series of intravitreal ceftazidime injections and adjuvant oral minocycline with recurrence of inflammation necessitating pars plana vitrectomy with intraocular lens removal and total capsulectomy. Inflammatory episodes recurred until residual capsule fragments were ablated using endoscopic vitrectomy. Since ablation over 18 months ago, no further recurrences have occurred and the patient has excellent visual outcome. CONCLUSION: A. terrae is a gram-negative bacillus recovered from polluted soil. This is the first case of postoperative endophthalmitis secondary to A. terrae and the first description of human infection caused by this newly identified microbe.

RESUMEN

BACKGROUND AND AIMS: Extra-intestinal manifestations (EIMs) are a common complication of inflammatory bowel diseases (IBD), affecting up to half of the patients. Despite their high prevalence, information on standardised definitions, diagnostic strategies, and treatment targets is limited. METHODS: As a starting point for a national EIM study network, an interdisciplinary expert panel of 12 gastroenterologists, 4 rheumatologists, 3 ophthalmologists, 6 dermatologists, and 4 patient representatives was assembled. Modified Delphi consensus methodology was used. Fifty-four candidate items were derived from the literature review and expert opinion focusing on five major EIMs (erythema nodosum, pyoderma gangrenosum, uveitis, peripheral arthritis, and axial arthritis) were rated in three voting rounds. RESULTS: For use in a clinical practice setting and as part of the creation of a prospective registry of patients with EIMs, the panel developed definitions for erythema nodosum, pyoderma gangrenosum, uveitis, peripheral arthritis, and axial arthritis; identified the appropriate and optimal subspecialists to diagnose and manage each; provided methods to monitor disease course; offered guidance regarding monitoring intervals; and defined resolution and recurrence. CONCLUSIONS: Consensus criteria for appropriate and optimal means of diagnosing and monitoring five EIMs have been developed as a starting point to inform clinical practice and future trial design. Key findings include straightforward diagnostic criteria, guidance regarding who can appropriately and optimally diagnose each, and monitoring options that include patient and physician-reported outcomes. These findings will be used in a national multicenter study network to optimise the management of EIMs.
