Quality-of-life metrics in pediatric uveitis

Comprehensive evaluation of functional vision, quality of life, and cognitive ability in pediatric uveitis

BACKGROUND

Pediatric uveitis may cause severe impairment of vision in children and affect their quality of life as well as cognitive ability. This study aims to evaluate the functional vision, visual-related and health-related quality of life, and cognitive ability in pediatric uveitis.

METHODS

Children with uveitis aged 5-16 years old completed six validated instruments to assess functional visual ability with Cardiff Visual Ability Questionnaire for Children (CVAQC), vision-related quality of life with Impact of Vision Impairment for Children (IVI-C), health-related quality of life with Pediatric Quality of Life Inventory (PedsQL), cognitive ability with Chinese Wechsler Intelligence Scale for Children (C-WISC), and depression and anxiety evaluation with Hospital Anxiety and Depression Scale (HAD).

RESULTS

The CVAQC, IVI-C, and PedsQL scores of pediatric uveitis were significantly lower than that of normal levels. Full-scale intelligence quotient (IQ) and performance IQ were significantly lower in pediatric uveitis patients with impaired vision in their best eye (visual acuity < 0.3) compared to those with a vision equal to or better than 0.3. Verbal IQ was significantly lower in male pediatric uveitis patients with impaired vision compared to those with a vision equal to or better than 0.3. Additionally, parents of pediatric uveitis patients with impaired vision generally had lower educational levels than parents of those with a vision equal to or better than 0.3.

CONCLUSIONS

Impaired vision caused by pediatric uveitis has a significant impact on children's functional visual ability and quality of life. The development of cognitive function in pediatric uveitis is also significantly hindered.

Physical and Psychosocial Health in Pediatric Uveitis Patients

BACKGROUND

To investigate the possible associations between childhood noninfectious uveitis and cardio-respiratory fitness, physical activity, health related quality of life and fatigue.

METHODS

Cross-sectional analysis of 23 patients with noninfectious uveitis, aged 8-18 years. BMI, exercise capacity, muscle strength and physical activity were measured. Health-related quality of life and fatigue were assessed. The results were compared to standardized values for age matched healthy children.

RESULTS

Twenty-three patients were included. Children with uveitis had a higher bodyweight and body mass index. Children with uveitis had lower cardio-respiratory fitness and they were less physically active, but they experienced a normal quality of life and normal fatigue. Parents of children with uveitis reported a lower quality of life and more fatigue for their children than parents of healthy children.

CONCLUSION

Our study indicates that children with noninfectious uveitis are at risk of developing lower physical and psychosocial health.

Development of a Nationally Agreed Core Clinical Dataset for Childhood Onset Uveitis

Background

Childhood onset uveitis comprises a group of rare inflammatory disorders characterized by clinical heterogeneity, chronicity, and uncertainties around long term outcomes. Standardized, detailed datasets with harmonized clinical definitions and terminology are needed to enable the clinical research necessary to stratify disease phenotype and interrogate the putative determinants of health outcomes. We aimed to develop a core routine clinical collection dataset for clinicians managing children with uveitis, suitable for multicenter and national clinical and experimental research initiatives.

Methods

Development of the dataset was undertaken in three phases: phase 1, a rapid review of published datasets used in clinical research studies; phase 2, a scoping review of disease or drug registries, national cohort studies and core outcome sets; and phase 3, a survey of members of a multicenter clinical network of specialists. Phases 1 and 2 provided candidates for a long list of variables for the dataset. In Phase 3, members of the UK's national network of stakeholder clinicians who manage childhood uveitis (the Pediatric Ocular Inflammation Group) were invited to select from this long-list their essential items for the core clinical dataset, to identify any omissions, and to support or revise the clinical definitions. Variables which met a threshold of at least 95% agreement were selected for inclusion in the core clinical dataset.

Results

The reviews identified 42 relevant studies, and 9 disease or drug registries. In total, 138 discrete items were identified as candidates for the long-list. Of the 41 specialists invited to take part in the survey, 31 responded (response rate 78%). The survey resulted in inclusion of 89 data items within the final core dataset: 81 items to be collected at the first visit, and 64 items at follow up visits.

Discussion

We report development of a novel consensus core clinical dataset for the routine collection of clinical data for children diagnosed with non-infectious uveitis. The development of the dataset will provide a standardized approach to data capture able to support observational clinical studies embedded within routine clinical care and electronic patient record capture. It will be validated through a national prospective cohort study, the Uveitis in childhood prospective national cohort study (UNICORNS).

Assessing the validity and reliability of the Effects of Youngsters' Eyesight on Quality of Life (EYE-Q) questionnaire among children with uveitis

PURPOSE

The Effects of Youngsters' Eyesight on Quality of Life (EYE-Q) questionnaire measures vision-related functioning (VRF) and vision-related quality of life (VRQOL) in children with uveitis. Our aim was to revise the Alpha version of the EYE-Q to refine VRF and VRQOL subscales and assess the validity of the EYE-Q.

METHODS

Children with juvenile idiopathic arthritis (JIA), JIA-associated uveitis, and other non-infectious uveitis were enrolled. Patients and parents completed the EYE-Q, PedsQL (overall QOL), and CHAQ (physical functioning). The Development site completed the Alpha version of the EYE-Q, and the Composite sites completed the Beta version. We compared item-subscale correlations, internal consistency, construct and discriminant validity amongst the different versions.

RESULTS

Of the 644 patients enrolled, 61.6% completed the Alpha version, and 38.4% the Beta version of the EYE-Q. Mean patient age was 11.1 (SD = 4.2) years, and 70% were female. Fewer white patients (73.5%) completed the Alpha version compared to the Beta version (86.2%, p <0.001). With the exception of patient-reported VRF, both versions had similar item-subscale correlations. Version comparisons on scale internal consistencies indicated significant differences for parent- and patient-reported VRF, but each scale had a Cronbach's Alpha >0.80 Beta. When data were combined, the EYE-Q showed significant differences between JIA-only and uveitis patients on all parent and patient scores, except for patient-reported VRF.

CONCLUSION

The EYE-Q appears to be a valid measure of VRF and VRQOL in pediatric uveitis. Our results suggest it may be used as an outcome measure in multi-center pediatric uveitis studies.

Quality of life in patients with uveitis: data from the ULISSE study (Uveitis: cLInical and medico-economic evaluation of a Standardised Strategy for the Etiological diagnosis)

AIMS

To assess vision-related (VR-QOL) and health-related quality of life (HR-QOL) in a large series of patients with de novo uveitis at baseline and 6-month follow-up.

METHODS

Non-inferiority, prospective, multicentre, cluster randomised controlled trial registered under the Unique Identifier: NCT01162070. VR-QOL and HR-QOL were assessed by the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) and the Medical Outcomes Study 36-item Short Form Survey (SF-36).

RESULTS

At inclusion, 466 patients completed the VFQ-25. The mean composite score was 80.0 (±16.7). In multivariate analysis, higher age, female sex and insidious onset were significantly associated with lower QOL. At 6 months, 138 patients completed the VFQ-25, with a significantly higher mean composite score of 82.6 (±16.7). SF-36 mental component was 42.9 (±11.3) and physical component was 47.2 (±8.5) at inclusion (n=425). HR-QOL improvement at 6 months was not clinically significant.

CONCLUSION

QOL seems relatively well preserved in this cohort; only VR-QOL improved significantly at 6 months, especially in patients with low initial visual acuity.

Outcomes in patients with chronic uveitis: which factors matter to patients? A qualitative study

Purpose

Outcome measurements currently used in chronic uveitis care fail to cover the full patient perspective. The aim of this study is to develop a conceptual model of the factors that adult patients with chronic uveitis consider to be important when evaluating the impact of their disease and treatment.

Methods

A qualitative study design was used. Twenty chronic uveitis patients were recruited to participate in two focus groups. Data were transcribed verbatim and analysed using thematic analysis in ATLAS.ti.

Results

Coding of the transcripts resulted in a total of 19 codes divided over five themes: 1) disease symptoms and treatment; 2) diagnosis and treatment process; 3) impact on daily functioning; 4) emotional impact; and 5) treatment success factors.

Conclusion

The conceptual model resulting from this study can contribute to the development of future uveitis specific measures in adults.

Quality of life in children suffering from juvenile idiopathic arthritis-associated uveitis

Uveitis (JIA-U), the most common extra-articular manifestation in juvenile idiopathic arthritis (JIA), may cause severe impairment of vision in children and affect their quality of life (QoL). Considering the lack of uveitis-related QoL assessment questionnaire, and multidimensional nature of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR), commonly used for monitoring and assessing the health status of children with JIA, we performed a cross-sectional study to investigate the potential of the JAMAR in estimation of QoL in children suffering from JIA-U. The study included 42 children with JIA, 21 of whom had JIA-U. Both children and their parents completed the JAMAR. We compared two groups of children (JIA-U and JIA without uveitis) and their parents against five extracted questionnaires items (QoL, functional ability, pain level, disease activity estimation, and current emotional state of the child) using the independent-samples t test to verify the differences and the Pearson correlation coefficient to measure the strength of a linear association between variables. No significant statistical difference in any of the examined variables was found between the two groups of children. In the groups of parents, current emotional state of children with JIA-U was assessed to be significantly worse (t = 2.05, p < 0.05) and the overall level of functioning significantly lower (t = 2.03, p < 0.05) than children without uveitis. Our results suggest the need for adding the uveitis-specific questionnaires items to JAMAR to improve its sensitivity and specificity in the assessment of QoL in children suffering from JIA-U, as well as designing a second assessment tool such as uveitis-specific questionnaires.

Ophthalmic medicine regulatory approvals through the European Centralised Procedure, 1999-2017: Clinical efficacy considerations

OBJECTIVES

Regulatory approval of new medicines requires a thorough assessment of the potential clinical benefits and risks. Study end-points are expected to demonstrate a clinically relevant treatment effect that will translate into direct patient benefits. This study sought to review the ophthalmic medicines with European Union-wide approval granted via the Centralised Procedure and characterise the key efficacy end-points underpinning the demonstration of clinical benefit.

METHODS

This study was a retrospective review of published data pertaining to the European regulatory authorisation of centrally approved ophthalmic products between 1999 and 2017, inclusive. All sources and data consulted are in the public domain. European Public Assessment Reports published by the European Medicines Agency were consulted for data concerning the pivotal clinical efficacy studies supporting the applications. Data analyses were descriptive.

RESULTS

The European Medicines Agency have authorised 30 products via the Centralised Procedure between 1999 and 2017. For these products, a total of 24 additional approvals for line extensions or additional therapeutic indications were granted. Four products have been approved for orphan indications, including one approval 'under exceptional circumstances' and one 'Conditional Marketing Authorisation'. Approvals for products in retina (36%) and glaucoma (28%) indications together accounted for the majority of authorisations, with trial end-points predominantly based on visual acuity and intraocular pressure parameters, respectively. Products were also approved for indications in ocular surface disease, inflammation, optic neuropathy and surgical adjuncts, with a range of functional and anatomical end-points.

CONCLUSION

Approvals for ophthalmic medicines have been granted for a range of clinical indications, representing a considerable portion of available major therapeutics for practitioners. Benefit-risk assessments rely on clinical trial data demonstrating a clearly relevant patient benefit.

Demographic and Clinical Features of Pediatric Uveitis in Israel

Purpose: To report the epidemiology, etiology, ocular characteristics, treatment and visual outcome of pediatric uveitis in Israel.Methods: Retrospective study from two tertiary uveitis centers.Results: Included were 107 patients (182 eyes), 55% females. Mean age at diagnosis 8.8 years. Uveitis was predominantly anterior, idiopathic, bilateral, and chronic. Systemic associations were seen in 36% of patients of which the most common disease was juvenile idiopathic arthritis. Infectious uveitis accounted for 37% of posterior uveitis cases of which toxoplasmosis was the most common cause. Anterior segment complications were commonly observed at presentation (41%); the most predominant were posterior synechiae, cataract, and band keratopathy. The most common posterior segment complications were papillitis, epiretinal membrane, and macular atrophy/scar. Ninety-three percent of eyes had visual acuity >20/40 at last follow-up.Conclusion: The pattern of pediatric uveitis in Israel is similar to that in the western world. Visual outcome was good in most eyes.

Chronic Anterior Uveitis in Children: Psychosocial Challenges for Patients and Their Families

PURPOSE

To describe issues of concern to children with chronic anterior uveitis; to consider the psychological impact of chronic anterior uveitis on children's lives; and to understand the effect of a child's chronic illness on other family members.

DESIGN

Expert commentary.

METHODS

Author experiences were supplemented by a review of pertinent medical literature and by consideration of content from semi-structured, separate patient and parent interviews.

RESULTS

Vision loss and the fear of blindness are not the only stressors for children with chronic anterior uveitis and their families; of additional concern are the burdens of examinations and treatment regimens, as well as drug toxicities. Children with chronic anterior uveitis experience medical, academic, interpersonal, psychological, and developmental challenges. The impact of disease extends to other members of a patient's family as well; parents experience challenges in similar domains. Problems with adherence to medical regimens are common. Both the disease and its treatment affect quality of life, and can interfere with successful management of disease and transition to autonomy in adulthood, as reported for other chronic conditions. Coping processes vary greatly between different families.

CONCLUSIONS

Eye examinations and the rigors of long-term treatment often influence the psychosocial health of patients and families; physicians who are aware of these issues can help patients and families cope with chronic illness and may improve outcomes. Further psychosocial research to understand the experiences of children dealing with chronic anterior uveitis is warranted; this commentary can serve as a foundation for development of age- and disease-specific research questions.

Cross sectional, qualitative thematic analysis of patient perspectives of disease impact in juvenile idiopathic arthritis-associated uveitis

BACKGROUND

Chronic health conditions in children can have a significant impact on their quality of life. The aim of this study was to explore the subjective experience of children and young people being treated for chronic, non-infectious uveitis associated with a systemic disease such as juvenile idiopathic arthritis.

METHODS

A semi-structured interview was conducted with 10 children and young people aged between 6 and 18 years of age and their parents.

RESULTS

Preliminary thematic analysis indicated that both the treatment and complications of the disorder have a significant impact on the quality of life and emotional well-being of patients, not only in terms of the discomfort experienced but also in perceptions of social isolation, anxiety and sense of injustice.

CONCLUSION

This study shows that themes including "impact on school", "social factors" and "emotional reactions" are important domains influencing health-related quality of life (HRQoL) in children with chronic uveitis. Inclusion of questions relating to these domains should be considered in future uveitis-specific tools examining HRQoL in these patients.

Inflammatory eye disease: Pre-treatment assessment of patients prior to commencing immunosuppressive and biologic therapy: Recommendations from an expert committee

AIM

To outline recommendations from an expert committee on the assessment and investigation of patients with severe inflammatory eye disease commencing immunosuppressive and/or biologic therapy.

METHOD

The approach to assessment is based on the clinical experience of an expert committee and a review of the literature with regard to corticosteroids, immunosuppressive drug and biologic therapy and other adjunct therapy in the management of patients with severe sight-threatening inflammatory eye disease.

CONCLUSION

We recommend a careful assessment and consultative approach by ophthalmologists or physicians experienced in the use of immunosuppressive agents for all patients commencing immunosuppressive and/or biologic therapy for sight threatening inflammatory eye disease with the aim of preventing infection, cardiovascular, metabolic and bone disease and reducing iatrogenic side effects.

Unmet Needs and Future Directions in Inflammatory Eye Disease

PURPOSE

To explore the unmet needs in the management of patients with severe inflammatory eye disease (IED), future directions for research and therapy, and to develop and facilitate access and delivery of better medical care to patients with severe IED.

METHODS

The unmet needs and future directions in inflammatory eye disease were identified and discussed by experts in relevant disciplines at a recent international conference.

RESULTS

A total of 14 major unmet needs were identified and discussed by experts in the areas of ophthalmology, rheumatology, infectious disease, and internal medicine, at an international conference. The major areas discussed are summarized in this review.

CONCLUSIONS

Identification of unmet needs in IED is seen as a first step in implementing changes in the way we diagnose and treat patients with these sight-threatening IEDs.

Using the Effects of Youngsters' Eyesight on Quality of Life Questionnaire to Measure Visual Outcomes in Children With Uveitis

OBJECTIVE

The Effects of Youngsters' Eyesight on Quality of Life (EYE-Q) is a novel measure of vision-related quality of life (QOL) and function in children. We aim to determine the validity of the EYE-Q in childhood uveitis.

METHODS

We abstracted medical record data on arthritis and uveitis in a convenience sample of children with juvenile idiopathic arthritis (JIA) and/or uveitis. In addition to the EYE-Q, parents and patients completed questionnaires on overall QOL (Pediatric Quality of Life Inventory [PedsQL]), and physical functioning (Childhood Health Assessment Questionnaire [C-HAQ]).

RESULTS

Among 57 children (8 JIA, 24 JIA and uveitis, 25 uveitis alone), 102 ocular examinations were performed within 1 month of completing questionnaires. Uveitis patients had bilateral disease (69%), anterior involvement (78%), synechiae (51%), and cataracts (49%). Children with vision loss in their better eye (visual acuity [VA] 20/50 or worse) had worse EYE-Q (P = 0.006) and PedsQL (P = 0.028) scores, but not C-HAQ scores. The EYE-Q moderately correlated with logMAR VA (rs  = -0.43), PedsQL (rs  = 0.43), and C-HAQ (rs  = -0.45), but was not correlated with anterior chamber cells or intraocular pressure. The PedsQL and C-HAQ did not correlate with VA or cells. There were strong correlations between the parent and child EYE-Q (rs  = 0.62). Cronbach's α for the child report was 0.91. The EYE-Q had strong test-retest reliability (rs  = 0.75).

CONCLUSION

The EYE-Q may be an important tool in the assessment of visual outcomes in childhood uveitis and an improvement over general measures in detecting changes in vision-related function.

Characteristics of a cohort of children with Juvenile Idiopathic Arthritis and JIA-associated Uveitis

BACKGROUND

Juvenile idiopathic arthritis-associated uveitis (JIA-U) can lead to poor visual outcomes and impact a child's quality of life (QOL) and function. Our aim is to identify risk markers of JIA-U and examine differences in the QOL of children with JIA and JIA-U.

METHODS

Rheumatology and ophthalmology record reviews and questionnaires were completed every 4-6 months on 287 children with JIA. We collected arthritis, uveitis, and QOL data. We examined data through last study visit.

RESULTS

There were 52/287 (18%) children with JIA-U who were younger at arthritis diagnosis, had oligoarticular persistent JIA, and ANA positive. Confirmed uveitis predictors were age at JIA diagnosis (OR = 0.86) and oligoarticular subtype (OR = 5.92). They had worse vision specific QOL and function, but similar general QOL. Blindness occurred in 17.5% of children but was more common in African American children compared to non-Hispanic Caucasian children ((5/7 (71%) vs. 2/29 (7%), p <0.001) despite a similar uveitis prevalence (22% vs. 16%). Both races had similar complications, although band keratopathy was more frequent in African Americans (75% vs. 15.6%, p = 0.003).

CONCLUSIONS

We confirm young age at JIA diagnosis and the oligoarticular JIA subtype as predictors of uveitis development. Although we were unable to identify predictors of ocular complications or blindness, AA children appeared to have a more severe disease course manifested by increased ocular complications, vision loss and blindness. Potential causes that warrant additional study include underlying disease severity, access to medical care and referral bias. Further investigation of the risk factors for vision-compromising uveitis and its' long-term effects should be conducted in a large racially diverse population.
