OA12 Comparing disease manifestations and outcomes in juvenile-onset SLE and adult-onset SLE patients: a nested case-control study within a Singapore cohort

Abstract Background/Aims To compare disease manifestations and outcomes of juvenile-onset SLE (jSLE) and adult-onset SLE (aSLE) patients using a nested case-control study of patients in a Singapore cohort. Methods A prospective cohort of SLE patients was established at Tan Tock Seng Hospital from 1 January 2002 to 31 December 2017. Sociodemographic, clinical, laboratory and treatment data were collected according to a standardised protocol. jSLE patients (≤18 years old) were selected from this cohort and matched for gender and disease duration in a 1:1 ratio with aSLE patients. Data from the enrolment visit (V0) and last visit (VL) were analysed in this study. Results There were 148 jSLE patients with sufficient information for analysis who were matched with 148 aSLE patients. Fever and lymphadenopathy (p < 0.001) and hypocomplementemia (p = 0.002 at V0) were significantly more common in jSLE, while cardiovascular manifestations were significantly more common in aSLE patients (p = 0.008 at VL). Disease activity measured by the SLE Disease Activity Index (SLEDAI) was higher in the jSLE group at V0 (median SLEDAI 4 vs 2, p=0.05) and at VL (median SLEDAI 2.5 vs 0, p = 0.007). A significantly higher proportion of jSLE patients received immunosuppressants (intravenous cyclophosphamide, mycophenolate mofetil, azathioprine and ciclosporin) (p = 0.003 at V0, p < 0.001 at VL) and intravenous methylprednisolone (p < 0.001 at V0 and VL) compared to aSLE patients. Conclusion A higher proportion of jSLE patients have fever, lymphadenopathy, hypocomplementemia, or more active disease requiring greater use of immunosuppressants compared to aSLE patients. Early diagnosis and treatment of jSLE may prevent development of major organ involvement, in particular renal and neuropsychiatric. Disclosure B.Y. Thong: None. Y. Khong: None. X. Lim: None. H.

Microstructural Changes in the Corpus Callosum in Systemic Lupus Erythematous.

Central nervous system (CNS) involvement in childhood-onset systemic lupus erythematosus (cSLE) occurs in more than 50% of patients. Structural magnetic resonance imaging (MRI) has identified global cerebral atrophy, as well as the involvement of the corpus callosum and hippocampus, which is associated with cognitive impairment. In this cross-sectional study we included 71 cSLE (mean age 24.7 years (SD 4.6) patients and a disease duration of 11.8 years (SD 4.8) and two control groups: (1) 49 adult-onset SLE (aSLE) patients (mean age of 33.2 (SD 3.7) with a similar disease duration and (2) 58 healthy control patients (mean age of 29.9 years (DP 4.1)) of a similar age. All of the individuals were evaluated on the day of the MRI scan (Phillips 3T scanner). We reviewed medical charts to obtain the clinical and immunological features and treatment history of the SLE patients. Segmentation of the corpus callosum was performed through an automated segmentation method. Patients with cSLE had a similar mid-sagittal area of the corpus callosum in comparison to the aSLE patients. When compared to the control groups, cSLE and aSLE had a significant reduction in the mid-sagittal area in the posterior region of the corpus callosum. We observed significantly lower FA values and significantly higher MD, RD, and AD values in the total area of the corpus callosum and in the parcels B, C, D, and E in cSLE patients when compared to the aSLE patients. Low complement, the presence of anticardiolipin antibodies, and cognitive impairment were associated with microstructural changes. In conclusion, we observed greater microstructural changes in the corpus callosum in adults with cSLE when compared to those with aSLE. Longitudinal studies are necessary to follow these changes, however they may explain the worse cognitive function and disability observed in adults with cSLE when compared to aSLE.

Cognitive Performance in Patients with Systemic Lupus Erythematosus Using the Ped-ANAM

Computerized batteries have been widely used to investigate cognitive impairment (CI) in patients with SLE. The aim of this study was to evaluate the cognitive performance of patients with SLE in relation to healthy controls using the Pediatric Automated Neuropsychological Assessment Metrics (Ped-ANAM) battery. In addition, we aimed to examine differences in Ped-ANAM scores according to age of disease onset, presence of disease activity, and disease damage. We included 201 consecutive adult-onset (aSLE) and childhood-onset SLE (cSLE) patients who were being followed at the hospital's rheumatology outpatient clinic and 177 healthy controls. We applied the percentage of correct answers on the Ped-ANAM subtests and the Performance Validity Index (PVI) metric and correlated them with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus Erythematosus Damage Index (SDI). Then, we established their relationships with neuropsychiatric systemic lupus erythematosus (NPSLE). We observed CI in a total of 38 (18.9%) SLE patients and 8 (4.5%) healthy controls (p < 0.001). CI was observed in eight (19.5%) cSLE patients and 32 (20%) aSLE patients (p = 0.8175). Individual analysis of the aSLE subtests showed a significant difference in all subtests compared to healthy controls; the greatest differences were in matching to sample (p < 0.001) and memory search ( p < 0.001). In the cSLE group, we observed a difference in the code substitution subtests (p = 0.0065) compared to the healthy controls. In the evaluation of clinical outcomes, disease activity was significantly correlated with CI in cSLE (r = 0.33; p = 0.042) and aSLE (r = 0.40; p = 0.001). We also observed an association between disease activity and neuropsychiatric manifestations (p = 0.0012) in aSLE. In conclusion, we determined that cognitive dysfunction, mainly in memory and attention, was more prevalent in patients with SLE. In both the cSLE and aSLE groups, disease activity was associated with worse cognitive function. This is the first study to use the Ped-ANAM in Brazil. Longitudinal studies are necessary to determine how the Ped-ANAM will perform over time.

Clinical and laboratorial outcome of different age-onset systemic lupus erythematosus patients in Jiangsu, China: a multicentre retrospective study

Studies on clinical features of systemic lupus erythematosus among different age-onset patients are lacking in China. This multicentre study aimed to systemically compare clinical manifestations, comorbidities, organ involvement, and laboratory findings among 797 Chinese juvenile-onset, adult-onset, and late-onset SLE (JSLE, ASLE, and LSLE) patients. They were classified into JSLE, ASLE, and LSLE groups if first diagnosed at < 18, 18–50, and > 50 years old, respectively. Chi-square test and analysis of variance were employed for categorical and continuous variables respectively. In younger-onset patients, the SLE Disease Activity Index 2000 score was significantly higher (JSLE vs. ASLE vs. LSLE = 17.43 ± 9.139 vs. 16.34 ± 8.163 vs. 14.08 ± 6.474, p = 0.031). Mucocutaneous symptoms (79.5% vs. 73.4% vs. 62.0%, p = 0.042), especially malar rash (76.1% vs. 66.1% vs. 53.5%, p = 0.011) occurred more frequently, and proteinuria rate was higher (54.5% vs. 56.3% vs. 36.6%, p = 0.007). In later-onset patients, cardiopulmonary involvement increased (11.4% vs. 24.3% vs. 29.6%, p = 0.012). In ASLE, hypoalbuminemia rate elevated (46.6% vs. 59.9% vs. 47.9%, p = 0.015). Our study demonstrated in a Chinese population that JSLE may be more active and suffer mucocutaneous disorders, while LSLE tended to suffer cardiopulmonary involvement at-onset. These findings may help identify treatment priorities when facing different age-onset SLE patients.

Kidney Function, Age, and Education as Contributors to Depression and Anxiety in Juvenile Systemic Lupus Erythematosus.

Juvenile systemic lupus erythematosus (JSLE) is diagnosed in children younger than 18 years of age. Depression and anxiety are common, but not well understood in JSLE. We investigated the clinical and psychological factors associated with the psychological manifestations of JSLE. Twenty-nine JSLE patients were recruited for the study. Patients completed surveys evaluating their psychological status and perceptions about their health. Medical records were used to obtain laboratory results. The JSLE patient population was compared with adult-onset SLE (ASLE) patients and unaffected controls. Kidney involvement was associated with depression in the JSLE patients. The BUN levels, BUN/creatinine ratio, and leukocyturia were all significantly associated with depressive symptoms. Multivariate analysis found that the BUN/creatinine ratio was the most predictive value for both depression and anxiety. Depressive symptoms in JSLE were less pronounced than in ASLE, although anxiety was not different. Age and education are likely to be protective against depression in the JSLE patients. These findings may indicate that symptomatology is an important indicator of whether the patient needs psychiatric care.

Kidney function, age, and education as contributors to depression and anxiety in juvenile systemic lupus erythematosus

Abstract Background: Juvenile systemic lupus erythematosus (JSLE) is diagnosed in children younger than 18 years of age. Depression and anxiety are common, but not well understood in JSLE. We investigated the clinical and psychological factors associated with the psychological manifestations of JSLE. Methods: Twenty-nine JSLE patients were recruited for the study. They responded to surveys testing their psychological status and perceptions about their health, including the Hospital Anxiety and Depression scale, the Fatigue Severity Scale, and a Medical outcomes questionnaire (the SF-36). Clinical lab results were obtained from the patients’ medical records. Univariate and multivariate analyses were used to compare the patient populations with adult-onset SLE (ASLE) patients and unaffected controls, finding indicators that correlated with depression and anxiety in JSLE patients. Results: Kidney disease was associated with depression in the JSLE patients. The BUN levels, BUN/creatinine ratio, and leukocyturia were all significantly associated with depressive symptoms. The BUN/creatinine ratio was the most predictive laboratory value for both depression and anxiety. The JSLE patients had less depression than the ASLE, although not less anxiety. JSLE patients had comparable levels of fatigue and pain to the adult-onset SLE patients. Age and education were protective against depression in the JSLE patients. Conclusions: Kidney function correlated with symptoms of depression and anxiety. This may mean that symptomatology is an important indicator of whether the patient needs psychiatric care. Age and education were likely protective against depression in the JSLE population.

Multi-pronged approach to enhance education of children and adolescents with lupus, caregivers, and healthcare providers in New Jersey: Needs assessment, evaluation, and development of educational materials.

Childhood Systemic Lupus Erythematosus (cSLE) patients are younger at diagnosis and have a more severe disease course compared to adult onset SLE patients and develop significant complications related to disease and or immunosuppression. Moreover, female and minority populations experience higher rates of cSLE, with African American, Afro-Caribbean, and Hispanic populations being at greatest risk and having poor prognosis. The Pediatric Alliance for Lupus initiative addressed the dearth in education and resources in a multi-stage process. First, we conducted a need assessment identifying knowledge gaps among healthcare providers (HCPs), and resources needed to care for cSLE patients and their families. Second, we educated HCPs about the diagnosis and treatment of cSLE by Continuing Medical Education (CME) sessions/webinars (presented here). Third, HCPs participated in a Quality Improvement (QI) program on cSLE approved by the American Board of Pediatrics Maintenance of Certification Part 4. Finally, patients and caregivers were educated through the development of appropriate, culturally and linguistically sensitive cSLE resources. PAL disseminated materials among HCPs and the community to improve the awareness of the availability of these materials. According to results from the statewide needs assessment (representative of every county throughout NJ), HCPs face significant challenges in providing care to cSLE patients and their families, in part due to the multi-systemic nature of the autoimmune disease. Based on this need, we developed educational sessions, with pre-post comparison data showing a significant increase in knowledge after HCP education. The 15 different materials developed as part of the endeavor is a major contribution to the cSLE community, HCPs and pediatric rheumatologists. Resources are available in multiple formats (PDF and web pages), and are accessible on the National Resource Center on Lupus, the latest web site of the Lupus Foundation of American that houses materials for SLE patients, their families, schools, HCPs, and the community at large.Improving cSLE knowledge will empower the children and adolescents and families by increasing their self-efficacy; and positively impact key health outcomes (transition readiness and HRQOL) that are not optimally addressed with current medical treatment alone.

Relationship Between Genetic Risk and Age of Diagnosis in Systemic Lupus Erythematosus.

Specific risk alleles for childhood-onset systemic lupus erythematosus SLE (cSLE) vs adult-onset SLE (aSLE) patients have not been identified. The aims of this study were to determine if there is an association (1) between non-HLA-related genetic risk score (GRS) and age of SLE diagnosis, and (2) between HLA-related GRS and age of SLE diagnosis. Genomic DNA was obtained from 2001 multiethnic patients and genotyped using the Immunochip. Following quality control, genetic risk counting (GRCS), weighted (GRWS), standardized counting (GRSCS), and standardized weighted (GRSWS) scores were calculated based on independent single-nucleotide polymorphisms from validated SLE loci. Scores were analyzed in a regression model and adjusted by sex and ancestral population. The analyzed cohort consisted of 1540 patients: 1351 females and 189 males (675 cSLE and 865 aSLE). There were significant negative associations between all non-HLA GRS and age of SLE diagnosis: P = 0.011 and r2 = 0.175 for GRWS; P = 0.008 and r2 = 0.178 for GRSCS; P = 0.002 and r2 = 0.176 for GRSWS (higher GRS correlated with lower age of diagnosis.) All HLA GRS showed significant positive associations with age of diagnosis: P = 0.049 and r2 = 0.176 for GRCS; P = 0.022 and r2 = 0.176 for GRWS; P = 0.022 and r2 = 0.176 for GRSCS; P = 0.011 and r2 = 0.177 for GRSWS (higher GRS correlated with higher age of diagnosis). Our data suggest that there is a linear relationship between genetic risk and age of SLE diagnosis and that HLA and non-HLA GRS are associated with age of diagnosis in opposite directions.

Onset age affects mortality and renal outcome of female systemic lupus erythematosus patients: a nationwide population-based study in Taiwan

The objective of this study was to investigate the impact of disease onset age on mortality and renal survival in female SLE patients. This nationwide, population-based, retrospective cohort study used data from the National Health Insurance Research Database of Taiwan. Female patients newly diagnosed with SLE from 2001 to 2004 were identified as the study cohort. A non-SLE group was matched for age, sex and initial diagnosis date (index date) as the comparison cohort. Co-morbidities, mortality rates and end-stage renal disease (ESRD) incidences were compared among SLE patients of different onset age. Hazard ratios with a 95% CI were determined by the Cox proportional hazard model to quantify the mortality rates and ESRD incidences. Juvenile-onset, adult-onset and late-onset SLE patients were categorized according to disease onset age: <18, 18-50 and >50 years old. In total, 513 juvenile-onset, 3076 adult-onset and 764 late-onset SLE patients were identified. Compared with non-SLE controls, the hazard ratios of mortality were 6.49 (95% CI 3.73, 11.32, P < 0.001) for juvenile-onset, 1.75 (95% CI 1.47, 2.08, P < 0.001) for adult-onset and 3.44 (95% CI 2.76, 4.28, P < 0.001) for late-onset SLE patients. The hazard ratios of incident ESRD were 20.28 (95% CI 12.79, 32.15, P < 0.001) for adult-onset lupus patients and 1.99 (95% CI 1.36, 2.93, P < 0.001) for late-onset patients. Female patients with late-onset SLE carried a higher risk of mortality than those with adult-onset disease in the presence of co-morbidities. Juvenile-onset SLE patients were at greatest risk of mortality, which is probably due to disease severity.

Childhood-onset disease carries a higher risk of low bone mineral density in an adult population of systemic lupus erythematosus

To study the BMD of patients with SLE according to the age of disease onset. Consecutive SLE patients were screened for BMD at the hip, lumbar spine and whole body by the dual-energy X-ray absorptiometry (DXA). Comparison was made between patients who had disease onset in childhood (<18 years) and adulthood (≥18 years). Factors associated with low BMD were studied by linear regression. A total of 395 SLE patients were studied (94% women; 11% childhood-onset disease). Osteoporosis of the lumbar spine and the hip/femoral neck was present in 20 and 10% of the patients, respectively. Childhood-onset SLE patients were less likely to be post-menopausal, but had significantly lower BMI, longer SLE duration and a higher frequency of ever use of high-dose CSs, CYC and AZA. Despite a significantly younger age, the BMD of the hip, femoral neck and lumbar spine was significantly lower in childhood- than adult-onset SLE patients. In linear regression models, childhood-onset disease was an independent factor for lower BMD at the lumbar spine (β = -0.18; P = 0.002), hip (β = -0.20; P = 0.001) and femoral neck (β = -0.16; P = 0.01) after adjustment for age, sex, BMI, smoking, menopause, SLE duration and damage index, duration and current dose of prednisolone treatment and the ever use of high-dose glucocorticoids, other immunosuppressive agents, calcium, vitamin D and the bisphosphonates. In adult SLE patients, childhood-onset disease carries a higher risk of osteoporosis, which may possibly be related to a higher cumulative dose of glucocorticoids used for more active disease and failure to achieve a normal peak bone mass during puberty.

Childhood-onset Systemic Lupus Erythematosus: Clinical presentation and prognosis in 31 patients

Objective. To determine the clinical features at onset, the disease course, and prognostic factors in children with SLE. Methods. The medical records of 31 patients with childhood-onset SLE were reviewed. Signs and symptoms at onset and during the course of the disease were documented as well as survival and SLICC/ACR damage index. The disease course was compared to 135 consecutive adult-onset SLE patients. Results. Childhood-onset SLE most frequently presented with fatigue, arthritis, fever, weight loss, and malar rash. During follow-up, the frequency of the presence of malar rash, anemia, leukocytopenia, and anti-dsDNA antibodies was significantly higher in childhood-onset than in adult-onset patients. Mean SLICC/ACR damage index was 2.6 after 4.7 years of follow-up. The presence of arthritis, anemia, and seizures at the onset of disease resulted in a 2.6 to 3.9 times higher chance of a severe disease course. Conclusion. Patients with childhood-onset SLE suffer from substantial morbidity. Arthritis, anemia, and seizures at onset may be indicators of poor prognosis.
