Uveitis in childhood-onset systemic lupus erythematosus patients: a multicenter survey

Clinical features of ocular damage in systemic lupus erythematosus and risk factors for hydroxychloroquine-related complications

Ocular damage in systemic lupus erythematosus (SLE) may cause insidious visual impairment, but its clinical features and the risk of hydroxychloroquine (HCQ)-related complications are still controversial. We performed a meta-analysis to evaluate ocular damage in SLE, the correlation between eye and systemic involvement, and the ocular side effects of treatment. The database PubMed, Embase, and Ovid were used for literature from reception to July, 2023, and the calculation was carried out with R. About 48,693 patients from 66 studies were included. The results indicated that ocular damage in SLE was insidious, appearing in 28 % of patients with no complaints. The most common symptoms and manifestations were dry eye (30 %) and keratoconjunctivitis sicca (26 %). Retinopathy was detected in 10 % of patients and was related to antiphospholipid antibodies (25 % versus 8 %). The proportion of retinopathy also significantly increased in patients with lupus nephropathy or neuropsychiatric systemic lupus erythematosus (risk ratio of 2.29 and 1.95, respectively). HCQ was used in 82 % of patients, of which 4 % suffered from ocular toxicity. HCQ-related retinopathy was dose-dependent. Dosage below 5 mg/kg/d was relatively effective and safe for long-term use, while routine examination was recommended.

Efficacy and Safety of Adalimumab in Pediatric Non-infectious Non-anterior Uveitis: Real-life Experience From the International AIDA Network Uveitis Registry

INTRODUCTION

Scientific evidence of the effectiveness of the tumor necrosis factor inhibitor adalimumab (ADA) in pediatric patients with non-infectious non-anterior uveitis is still limited. The aim of this study is to investigate the therapeutic role of ADA in a cohort of pediatric patients with non-anterior uveitis.

METHODS

This is an international multicenter study analyzing real-life data referred to pediatric patients treated with ADA for intermediate uveitis/pars planitis, posterior uveitis and panuveitis. Data were drawn from the AutoInflammatory Disease Alliance (AIDA) registry for patients with uveitis.

RESULTS

Twenty-one patients (36 affected eyes) were enrolled, and all patients benefited from ADA administration. In detail, 11 patients (19 affected eyes) did not experience further ocular inflammation after ADA introduction; 10 cases (17 affected eyes) showed a significant clinical improvement consisting of a decrease in severity and/or frequency of ocular relapses. The number of ocular flares dropped from 3.91 to 1.1 events/patient/year after ADA introduction (p = 0.0009); macular edema and retinal vasculitis were respectively observed in 18 eyes and 20 eyes at the start of ADA and in 4 eyes and 2 eyes at the last assessment. The mean daily glucocorticoid dosage significantly decreased from 26.8 ± 16.8 mg/day at the start of ADA to 6.25 ± 6.35 mg/day at the last assessment (p = 0.002). Intermediate uveitis/pars planitis (p = 0.01) and posterior uveitis (p = 0.03) were more frequently observed in patients with full response to ADA; panuveitis (p = 0.001) was significantly more frequent among patients continuing to experience uveitic flares. This could be related to a higher use of systemic glucocorticoids (p = 0.002) and conventional immunosuppressants (p = 0.007) at the start of ADA when treating intermediate uveitis/pars planitis. Regarding the safety profile, only one adverse event was reported during ADA treatment, consisting of the development of generalized adenopathy.

CONCLUSIONS

ADA proved to have an effective therapeutic role in all pediatric patients with non-anterior uveitis enrolled in the study. An overall glucocorticoid-sparing effect was observed despite the severity of cases enrolled. A more aggressive treatment of panuveitis and posterior uveitis at start of ADA could increase the likelihood of full response to therapy.

The full range of ophthalmological clinical manifestations in systemic lupus erythematosus

Purpose

To determine the full range of ophthalmological clinical manifestations in systemic lupus erythematosus (SLE) and to compare the systemic features associated with them.

Methods

Files of 13 patients with ocular SLE (n = 20 eyes) diagnosed as per the American College of Rheumatology (ACR) 2012 revised criteria were retrospectively reviewed.

Results

The following clinical manifestations were found: keratoconjunctivitis sicca (n = three patients), anterior uveitis associated with an inflammatory pseudo-tumor orbital mass (n = one patient, one eye), episcleritis and periorbital edema (n = one patient, two eyes), posterior scleritis (n = one patient, two eyes), bilateral papillary edema in the context of idiopathic intracranial hypertension (n = one patient, one eye), inflammatory optic neuritis (n = one patient, one eye), and lupus retinopathies with varying degrees of capillary occlusions mainly arteriolar (n = seven patients, 13 eyes) and larger arteries or veins (retinal arteries occlusions and retinal veins occlusions) (n = one patient, two eyes). Some patients presented with combined ophthalmological manifestations.Systemic SLE was discovered by its ophthalmic manifestation in three cases (23%) and was previously known in the other 10 cases (77%). On average, ocular symptoms were seen 8 years after the initial diagnosis of SLE. Other systemic SLE disorders included cutaneous disorders (77%), joint disorders (38%), central nervous system (CNS) disorders (23%), renal disorders (38%), and oral ulcers (23%).Treatment of the ophthalmic system manifestations of lupus included local steroid therapies along with systemic immunosuppression.The most common laboratory ACR criteria were: high levels of antinuclear antibodies (ANA) (100%), positive anti-Sm (64%), anti-dsDNA (27%), low complement levels (27%), and positive antiphospholipid (APL) antibodies (18%).

Discussion

SLE activity in the ophthalmic system is characterized by its functional severity and the range of involvement can be categorized by anatomical involvement: presence of anterior uveitis, episcleritis, scleritis, periorbital edema, posterior uveitis with retinal vascular ischemia, or papillary edema. Not currently part of the diagnosis criteria of the SLE ACR given its rarity, the ocular localization of the pathology led to the diagnosis of SLE in three cases; thus, developing a greater understanding of ocular lupus may help in identifying and treating systemic manifestations of lupus earlier.

Epidemiology of disease-activity related ophthalmological manifestations in Systemic Lupus Erythematosus: A systematic review

OBJECTIVE

Ophthalmic complications in Systemic Lupus Erythematosus (SLE) are broad and can occur in up to a third of patients. The British Isles Lupus Assessment Group (BILAG) 2004 Index identifies 13 ocular manifestations of active SLE, as opposed to those related to previous disease activity and/or the consequences of therapy. We conducted a systematic review of published literature to determine the frequency of ophthalmic manifestations of active SLE.

METHODS

A systematic literature search of Ovid MEDLINE and EMBASE from their respective inceptions to July 2020 was conducted to identify cohort, case-control and cross-sectional studies.

RESULTS

22 studies meeting eligibility criteria were included. Most studies featured small sample sizes and were judged to have a high risk of methodological bias. The number and quality of studies did not allow us to confidently estimate the incidence of the conditions. No studies reported epidemiological data for orbital inflammation/myositis/proptosis. The prevalence of each of the other ocular manifestations, with the exception of retinal vaso-occlusive disease, was consistently less than 5%. Retinal vasculitis, uveitis and isolated cotton wool spots tended to be associated with more active SLE disease.

CONCLUSION

The prevalence of eye disease due to SLE activity is uncommon, but clinicians should be aware that some conditions tend to be associated with more active systemic disease. Further studies to determine the incidence and risk factors for these ophthalmic manifestations are needed.

An Update on the Management of Childhood-Onset Systemic Lupus Erythematosus

Childhood-onset systemic lupus erythematosus (cSLE) is a prototype of a multisystemic, inflammatory, heterogeneous autoimmune condition. This disease is characterized by simultaneous or sequential organ and system involvement, with unpredictable flare and high levels of morbidity and mortality. Racial/ethnic background, socioeconomic status, cost of medications, difficulty accessing health care, and poor adherence seem to impact lupus outcomes and treatment response. In this article, the management of cSLE patients is updated. Regarding pathogenesis, a number of potential targets for drugs have been studied. However, most treatments in pediatric patients are off-label drugs with recommendations based on inadequately powered studies, therapeutic consensus guidelines, or case series. Management practices for cSLE patients include evaluations of disease activity and cumulative damage scores, routine non-live vaccinations, physical activity, and addressing mental health issues. Antimalarials and glucocorticoids are still the most common drugs used to treat cSLE, and hydroxychloroquine is recommended for nearly all cSLE patients. Disease-modifying antirheumatic drugs (DMARDs) should be standardized for each patient, based on disease flare and cSLE severity. Mycophenolate mofetil or intravenous cyclophosphamide is suggested as induction therapy for lupus nephritis classes III and IV. Calcineurin inhibitors (cyclosporine, tacrolimus, voclosporin) appear to be another good option for cSLE patients with lupus nephritis. Regarding B-cell-targeting biologic agents, rituximab may be used for refractory lupus nephritis patients in combination with another DMARD, and belimumab was recently approved by the US Food and Drug Administration for cSLE treatment in children aged > 5 years. New therapies targeting CD20, such as atacicept and telitacicept, seem to be promising drugs for SLE patients. Anti-interferon therapies (sifalimumab and anifrolumab) have shown beneficial results in phase II randomized control trials in adult SLE patients, as have some Janus kinase inhibitors, and these could be alternative treatments for pediatric patients with severe interferon-mediated inflammatory disease in the future. In addition, strict control of proteinuria and blood pressure is required in cSLE, especially with angiotensin-converting enzyme inhibitor and angiotensin receptor blocker use.

Structural Retinal Assessment Using Optical Coherence Tomography and Fundus Fluorescein Angiography in Systemic Lupus Erythematosus Patients

BACKGROUND

Ocular manifestations in systemic lupus erythematosus (SLE) can be the presenting symptom of the disease or a sight-threatening complication.

OBJECTIVES

To detect different structural retinal changes in patients with SLE who had no ophthalmological symptoms and investigate the relationship between different retinal changes and the disease activity assessed by the Systemic Lupus Erythromatosus Disease Activity Index score.

STUDY DESIGN

A descriptive pilot study from January 2016 to January 2017.

METHODS

Fifty-two eyes of 26 patients diagnosed to have SLE were examined using visual acuity assessment, fundus examination, optical coherence tomography (OCT), and fundus fluorescein angiography (FFA).

RESULTS

Fundus fluorescein angiography showed different changes in the form of venular occlusion and optic nerve leakage. There were also degenerative changes in the form of alternating hyperfluorescent and hypofluorescent areas outside the arcades as well as peripapillary areas and capillary dropout. Optical coherence tomography detected signs of degenerative thinning, incomplete posterior vitreous detachment, and epiretinal membrane. A significant correlation was found between SLE activity and the changes detected by FFA (p = 0.017). However, there was no significant correlation between disease activity and changes detected by OCT. Optical coherence tomography changes were significantly correlated with the duration of hydroxychloroquine use of more than 5 years (p = 0.032). There was no correlation between FFA or OCT changes and proteinuria or antiphospholipid antibodies.

CONCLUSIONS

Fundus fluorescein angiography is more sensitive in detecting early subclinical retinal changes in patients with SLE, which correlates with disease activity, whereas OCT is more sensitive in detecting changes resulting from hydroxychloroquine use.

Epidemiological and advanced therapeutic approaches to treatment of uveitis in pediatric rheumatic diseases: a systematic review and meta-analysis

Background

Despite the low prevalence of uveitis in pediatric rheumatic diseases, potential problems as well as high disease burden can complicate its management. In this review, we systematically assessed the epidemiological, etiological, and managerial aspects of uveitis in pediatric rheumatic diseases.

Methods

This current study was conducted in accordance with the established methods and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). We searched the manuscript databases, including Medline, Web of Knowledge, Google Scholar, Scopus, and Cochrane for all eligible studies in line with the considered keywords. We also conducted the statistical analysis using the Stata software.

Results

Considering studies focusing on uveitis in Juvenile Idiopathic Arthritis (JIA) yielded a pooled prevalence of 11.8% (95%CI: 11.2 to 12.4%) for uveitis following JIA. In this regard, the prevalence rate of uveitis related to Behçet^,s disease and Systemic Lupus Erythematosus (SLE( was estimated to be 15.0 and 0.8%, respectively. The pooled response rate to Adalimumab and Infliximab was estimated to be 68.0% (95%CI: 65.4 to 70.6%), 64.7% (95%CI: 59.8 to 69.3%), respectively. The documents for the systematical assessment of other biological medications (e.g. Tocilizumab, Daclizumab and Rituximab) were inadequate; however, the mean response rate for these drugs was 59, 75 and 80%, respectively. Our meta-analysis showed a pooled response rate of 40.0% (95%CI, 36.0% to 44.2) to Methotrexate. Significant heterogeneity and significant diffusion bias were demonstrated by reviewing studies.

Conclusions

The pooled prevalence of uveitis in pediatric rheumatic diseases widely varied based on the underlying disease requiring more investigations in different subtypes of rheumatic diseases. The biologic medications, especially Adalimumab are the most effective treatments for uveitis in pediatric rheumatic diseases; however, a combination of the safe, available alternatives is preferred to achieve the most desirable treatment response.

Epidemiology and management practices for childhood-onset systemic lupus erythematosus patients: a survey in Latin America

To assess epidemiology and management practices of Latin America Pediatric Rheumatologists (LAPR) about childhood-onset systemic lupus erythematosus (cSLE). A cross-sectional study was performed in 288 LAPR PANLAR members based on online survey about cSLE practices. The response rate of web-based survey by LAPR was 170/288(59%) and the majority worked in university hospitals (63%). The ACR and/or SLICC classification criteria (99%) and disease activity tools (97%) were almost universally used by LAPR, whereas damage index (70%) and CHAQ (58%) instruments were less frequently used. Laboratory exams, diagnostic imaging, and biopsies were generally available (> 75%), however low availability for densitometry (66%). Drug access was excellent for the most common prescribed medications (> 75%), except for belimumab (11%). Emerging mosquito-borne diseases were also reported: dengue (20%), chikungunya (11%), and Zika (8%). Groups were further divided in two, according to the median number of cSLE patients followed by LAPR in the last year: groups A and B (≥ 25 and < 25, respectively). Frequencies of condom in combination with other contraceptive methods were significantly higher in group A than B (p = 0.01). The frequencies of reported pregnancy (p < 0.001) and non-adherence to therapy were significantly higher in group A (p = 0.023). Alcohol intake (p = 0.004) and illicit drug use (p = 0.007) were also reported more frequently by LAPR of group A in at least one cSLE patient. This first large web-based survey demonstrated an overall excellent access for diagnosis and therapy by LAPR, probably related to their high rate of practices in tertiary care of university hospitals. Adherence to therapy, pregnancy, and substance abuse was identified as major challenges in this population, particularly in larger centers.
