Interobserver Reliability and Sensitivity to Change of a Composite Ocular Inflammatory Activity Index: UVEDAI©.

INTRODUCTION: This was a multicenter, prospective, longitudinal, observational study involving eight Spanish tertiary hospitals to determine the interobserver reliability of an uveitis disease activity index, (UVEDAI) and assess its sensitivity to change in patients with receiving pharmacologic treatment. METHODS: Patients aged ≥ 18 years diagnosed with active noninfectious uveitis were included. A complete baseline assessment was performed by two ophthalmologists who determined ocular inflammatory activity using the UVEDAI index independently of each other. The principal ophthalmologist made a new visit at 4 weeks to determine the change in inflammatory activity. The interobserver reliability analysis was performed by calculating the intraclass correlation coefficient (ICC), with the values of the variables and the UVEDAI obtained by both ophthalmologists in the more active eye at the baseline visit. Sensitivity to change in the UVEDAI index was assessed at 4 weeks from the start of pharmacologic treatment by determining the clinically relevant change, defined as a change in UVEDAI of ≥ 0.8 points over baseline. The mean change between both measures was compared using the repeated-measures t-test. RESULTS: A total of 111 patients were included. In the interobserver reliability analysis, the ICC for the UVEDAI value was 0.9, and, when compared with the mean UVEDAI values obtained by the ophthalmologists, no statistically significant differences were found (p value > 0.05). As for the sensitivity to change in UVEDAI, statistically significant differences (p value = 0.00) were found for the mean values of the index compared with baseline. In all cases, the index value decreased by > 1 point at the 4-week visit. CONCLUSIONS: The interobserver reliability of the UVEDAI was high in the total sample. Furthermore, the index was sensitive in determining the change in inflammatory activity after treatment. We believe that UVEDAI is a disease activity index that enables objective comparison of results in clinical practice and trials.

An Observational Study in the Real Clinical Practice of the Treatment of Noninfectious Uveitis.

BACKGROUND: The aim of this study was to describe the characteristics of patients with uveitis associated with an immunologic or idiopathic disease that requires immunosuppressive treatment and the response to such treatments in real clinical practice. METHODS: An observational, descriptive, longitudinal, and retrospective study of a cohort of patients diagnosed with noninfectious uveitis was performed. To assess the response to treatment, we evaluated the change in visual acuity, vitritis, and the presence of macular edema. RESULTS: We included 356 patients. Overall, 12% required treatment with systemic corticosteroids, and 66 patients (18.5%) required immunosuppressive/biological treatment, with methotrexate being the most used (55%). Immunosuppressive drugs were used in 59 cases (in 56 patients, as the first choice of treatment and for 3 patients as the second choice after treatment with biologics). Treatment with biologics was the first choice in 10 patients out of 66 (15%), and 34 (48%) required them at some time during the disease, with adalimumab being the most commonly used. Thirty-five patients (53%) needed to switch drugs due to a lack of response to the first one. There were no differences between different drugs in the resolution of vitritis and improvement in vision. CONCLUSIONS: The use of systemic corticosteroids and immunosuppressive/biologics was necessary for a high number of patients with noninfectious uveitis. In our series, tocilizumab was significantly more effective in the resolution of macular edema.

Seroprevalencia del SARS-CoV-2 en los pacientes con enfermedades inmunomediadas en tratamiento con terapias biológicas y sintéticos dirigidos / Seroprevalence of SARS-CoV-2 antibodies in patients with immune-mediated inflammatory diseases treated with biological and synthetic targeted therapies

INTRODUCCIÓN: La seroprevalencia del SARS-CoV-2 en las enfermedades inflamatorias inmunomediadas (IMID) sigue siendo fuente de controversia. OBJETIVO: Comparar la seroprevalencia de anticuerpos (Ac) anti SARS-CoV-2 en pacientes con IMID en tratamientos con fármacos antirreumáticos modificadores de la enfermedad biológicos (FAMEb) o sintéticos dirigidos (FAMEsd) frente a un grupo de personas sin IMID. MÉTODOS: Estudio de pacientes con IMID y tratamientos con FAMEb y FAMEsd y de individuos sin IMID. Mediante la técnica de inmunoensayo por quimioluminiscencia indirecta, se determinaron las serologías IgG frente al SARS-CoV-2 entre octubre/2020 y mayo/2021. RESULTADOS: Se estudiaron 1.100 sujetos, 550 pacientes con IMID y 550 personas sin IMID. Se observó una seroprevalencia de 16% (88/550) en los pacientes frente a 19,3% (106/550) en el grupo de personas sin IMID, sin significación estadística (OR 0,790 [IC 95% 0,558-1,118]). Comparando los tratamientos con FAMEb o FAMEsd, se observó una tendencia a una menor seroprevalencia con rituximab, en relación con los individuos sin IMID (OR 0,296 [IC 95% 0,0871,007]). Asimismo, se encontró menor seroprevalencia en los pacientes que además de su FAMEb recibían tratamiento con metotrexato, en comparación con el grupo de personas sin IMID (OR 0,432 [IC 95% 0,223-0,835]). CONCLUSIONES: Las IMID en tratamiento con FAMEb o FAMEsd no influyen en la seroprevalencia frente al SARS-CoV-2 de los pacientes. El tratamiento concomitante con metotrexato disminuye de forma significativa la seroprevalencia en estos pacientes.

BACKGROUND: The seroprevalence of SARS-CoV-2 in immunemediated inflammatory diseases (IMID) remains controversial. AIM: To compare the seroprevalence of antibodies (Ab) to SARS-CoV-2 in patients with IMID receiving treatment with biological diseasemodifying antirheumatic drugs (bDMARD) or targeted synthetic (tsDMARD) versus a group of people without IMID. METHODS: Study of patients with IMID and treatments with bDMARD and tsDMARD and individuals without IMID. IgG serology against SARS-CoV-2 was measured using the two-step sandwich immunoassay technique by indirect chemiluminescence between October 2020 and May 2021. RESULTS: A total of 1100 subjects were studied, 550 patients with IMID and 550 persons without IMID. A seroprevalence of 16% (88/550) was observed in patients versus 19.3% (106/550) in the group of people without IMID, without statistical significance (OR 0.790 [95% CI 0.558-1.118]). Comparing the treatments with bD- MARD or tsDMARD, there was a tendency to lower seroprevalence with rituximab, in relation to individuals without IMID (OR 0.296 [95% CI 0.087-1.007]). In addition, lower seroprevalence was found in patients who received methotrexate treatment in addition to their bDMARD, compared to the group of individuals without IMID (OR 0.432 [95% CI 0.223-0.835]). CONCLUSIONS: IMIDs in treatment with bDMARDs or tsDMARDs do not influence the seroprevalence against SARS-CoV-2 in patients. Concomitant treatment with methotrexate significantly decreased seroprevalence in these patients.

Validation of UVEDAI: An Index for Evaluating the Level of Inflammatory Activity in Uveitis.

INTRODUCTION: Uveitis is the inflammation of the middle layer of the eye, the uvea, and is a major cause of blindness. None of the instruments used in clinical practice are, in themselves, sufficient to evaluate the course of uveitis. Therefore, it is necessary to develop instruments enabling standardized measurement of inflammatory activity. We developed a composite disease activity index for patients with uveitis known as UVEDAI, which considers the overall activity of the eye. The objective of this study was to validate the composite index of ocular inflammation, UVEDAI. METHODS: A multicenter cross-sectional study involving eight Spanish tertiary hospitals. Sixty-two patients aged ≥ 18 years with acute uveitis were recruited. Participants gave informed consent before participating in the study. A full ophthalmological examination was performed by two ophthalmologists to determine inflammatory activity: one used the UVEDAI score and the other used clinical judgment. The ophthalmologists did not share their findings with each other to avoid introducing bias into the analysis. Construct validity was established by means of factor analysis. The criterion validity of the index was determined using an ordinal multivariate regression model, in which the dependent variable was the degree of uveal inflammation (mild, moderate, or high/severe). Cut-off points were determined for the UVEDAI and for the receiver operating characteristic (ROC) curves. RESULTS: Sixty-two patients were included. Total variance with the three components accounted for 80.32% of the construct validity. Each of the three components identified one type of eye involvement. The discriminatory capacity of UVEDAI was 0.867 (95% CI 0.778; 0.955 p < 0.001) for mild versus moderate-high and 0.946 (95% CI 0.879; 1.000 p < 0.001) for high versus mild-moderate. CONCLUSIONS: The variables included in UVEDAI enable ocular inflammatory activity to be described with a high degree of accuracy. The index may be used to evaluate and classify this activity with considerable discriminatory power.

Clinical Characteristics, Frailty, and Mortality of Residents With COVID-19 in Nursing Homes of a Region of Madrid.

OBJECTIVES: To describe the clinical characteristics, 30-day mortality, and associated factors of patients living in nursing homes (NH) with COVID-19, from March 20 to June 1, 2020. DESIGN: This is a retrospective study. A geriatric hospital-based team acted as a consultant and coordinated the care of older people living in NHs from the hospital. SETTING AND PARTICIPANTS: A total of 630 patients aged 70 and older with Coronavirus Disease 2019 COVID-19 living in 55 NHs. METHODS: A logistic regression was performed to analyze the factors associated with mortality. In addition, Kaplan-Meier curves were applied according to mortality and its associated factors using the log-rank Mantel-Cox test. RESULTS: The diagnosis of COVID-19 was mainly made by clinical compatibility (N = 430). Median age was 87 years, 64.6% were women and 45.9% were transferred to be cared for at the hospital. A total of 282 patients died (44.7%) within the 30 days of first attention by the team. A severe form of COVID-19 occurred in 473 patients, and the most frequent symptoms were dyspnea (n = 332) and altered level of consciousness (n = 301). According to multiple logistic regression, male sex (P = .019), the Clinical Frailty Score (CFS) ≥6 (P = .004), dementia (P = .012), dyspnea (P < .001), and having a severe form of COVID-19 (P = .001), were associated with mortality, whereas age and care setting were not. CONCLUSIONS AND IMPLICATIONS: Mortality of the residents living in NHs with COVID-19 was almost 45%. The altered level of consciousness as an atypical presentation of COVID-19 should be considered in this population. A severe form of the disease, present in more than three-quarters of patients, was associated with mortality, apart from the male sex, CFS ≥6, dementia, and dyspnea, whereas age and care setting were not. These findings may also help to recognize patients in which the Advance Care Planning process is especially urgent to assist in the decisions about their care.

Inflammatory Relapses after Immunosuppressive Drug Discontinuation in Uveitis Patients: A Survival Analysis.

Purpose: To estimate the incidence rate (IR) and identify risk factors associated to inflammatory relapse after immunosuppressive drug (ISD) discontinuation in noninfectious uveitis patients.Methods: Multicenter longitudinal retrospective study, including patients from four uveitis clinics followed-up until December 2018. Hazard ratios for different variables were estimated using multivariable Cox models.Results: 32 patients (34 episodes of ISD discontinuation) were analyzed (median and maximum follow-up time: 2.4 and 19.2 years, respectively). Fourteen patients presented at least one relapse: anterior (8 patients), intermediate (5) and posterior (8). IR (95% confidence interval) of the first relapse was 14.3 (8.6-23.8) episodes per 100 patient-years (median survival time: 4.8 years). Early use of ISDs, panuveitis, and higher oral corticosteroid dosage at discontinuation were associated with higher hazards of relapse in multivariable analysis.Conclusions: Relapse is a frequent and early event after ISD discontinuation. Identifying relapse risk factors could support the physician's decision regarding ISD discontinuation.

Visual acuity loss and development of ocular complications in white dot syndromes: a longitudinal analysis of 3 centers.

PURPOSE: To compare the clinical prognosis among selected white dot syndromes (WDS) (birdshot chorioretinopathy (BRC), multifocal choroiditis, serpiginous choroidopathy (SC), and others) and to identify risk factors of poor visual prognosis. METHODS: Retrospective longitudinal cohort study including 84 patients (143 affected eyes) diagnosed with WDS between 1982 and July 2017, followed up until loss of follow-up or December 2017, and recruited from three Uveitis Clinics (Madrid Community, Spain). Our main outcome measures were temporary or permanent moderate (corrected visual acuity in the Snellen scale < 20/50) or severe (< 20/200) vision losses, and development of new ocular complications. Incidence rates (IR) of the main outcome measures were estimated per 100 eye-years. Bivariate and multivariate Cox robust regression models analyzed the association of demographic- and clinical-related variables with vision loss. RESULTS: SC exhibited the greatest IR of vision loss, even in the multivariate models. Previous events of vision loss, presence of choroidal neovascularization, and cataracts exhibited worse visual prognosis. Monotherapy with immunosuppressive drugs but not combine therapy was also associated with higher IR of visual loss. Regarding new ocular complications, BRC showed the highest IR of epiretinal membrane and macular edema. CONCLUSIONS: SC presents the worst visual prognosis. Some ocular manifestations can identify patients with WDS at risk of a worse clinical evolution.
