MentorOn: A peer mentoring program developed for COVID-19 times

Burgeoning research has documented COVID-19's detrimental impacts globally, especially on the lives of adolescents. The present study examined the positive influences of a virtual, cross-age peer mentoring program on the development of adolescent participants in the face of the hardships created by the pandemic. In particular, this study focuses on the experiences of high school participants who served as both mentors and mentees in the program. Semi-structured interviews with participating high schoolers (n = 13) were coded and analyzed using the thematic analysis process. The interview data indicated that increased social support, the agency in prosocial pursuits, and greater purpose engagement resulted from their participation in the program. Results are discussed in the context of self-determination theory: youths' needs for relatedness, competence, and autonomy. The program met these basic needs among participants which in turn supported purpose exploration during the pandemic.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care

OBJECTIVE

The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis.

METHODS

We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded.

RESULTS

We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers.

CONCLUSION

In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry

BACKGROUND

Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months.

METHODS

We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed.

RESULTS

We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05).

CONCLUSION

While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

POS1314 VALIDATION OF A PEDIATRIC-SPECIFIC ULTRASOUND SCORING SYSTEM FOR THE EVALUATION OF WRIST, FINGER, AND ANKLE SYNOVITIS

Background

Juvenile Idiopathic Arthritis (JIA) is the most common chronic rheumatic disease in children. Clinical evaluation of arthritis is a subjective measurement. Musculoskeletal ultrasound (MSUS) is increasingly being utilized in children. In order to provide objective assessments of arthritis, reliable and validated MSUS scoring systems are needed. Recently, a joint-specific scoring system for the assessment of arthritis of the pediatric ankle, wrist and finger joints were proposed[1, 2].

Objectives

This study aims to further validate the MSUS scoring system for the assessment of finger, wrist, and ankle arthritis

Methods

JIA patients with finger, wrist, and ankle arthritis as per expert clinician evaluation are eligible for this study. A comprehensive wrist, ankle, and finger (2-5th metacarpal and 2-5th proximal interphalangeal joints) MSUS examination by an American College of Rheumatology MSUS certified pediatric rheumatologist is performed an all enroll subjects. MSUS are scored using the semiquantitative (grade 0 to 3) scoring systems previously proposed. A subset of participants receives an MRI with contrast of the targeted joint immediately after MSUS performance. MRI findings are read for presence of synovitis, tendonitis and enthesitis by a pediatric radiologist with expertise on musculoskeletal imaging. For the analysis of the current report, MRIs were classified as having presence or absence of findings of JIA disease based on the pediatric radiologist expert opinion. MSUS were classified as normal (grade 0 and 1) or abnormal (grade 2 and 3). Cohen’s Kappa Coefficient was used to assess the level of agreement between MSUS (normal and abnormal) and MRI with contrast (absence or presence of disease) for each targeted joint. Tetrachoric Correlation was used to assess the strength of the association. Fisher’s Exact test was used to determine statistical significance at p < 0.05 level.

Results

A total of 52 children aged 2 – 18 years old have been enrolled in this study. To date 20 MSUS of the finger(s), 33 MSUS of the wrist, and 43 MSUS of the ankle joints have been collected. Three MRI of the 2-5 fingers (12 fingers total), 6 MRI of the wrist, and 5 MRI of ankle have been obtained through the study. Preliminary results of this effort reveal that for the ankle joint there is moderate agreement (Kappa coefficient 0.53 (confidence interval (CI)=0.14-0.92)) between MRI and US and a strong positive tetrachoric correlation (0.79) (p = 0.03). While the Kappa coefficient for comparing MRI and US finding on wrist joint indicated moderate agreement (Kappa 0.62 [0.15-1.00]) with a strong tetrachoric correlation (0.83) the Fisher’s exact test indicated a trend rather than statistically significant results (p = 0.07). The Kappa coefficient for MCPs and PIPs joints indicated strong agreement between MRI and US (Kappa 0.83 [CI=0.52-1.00] and 0.80 [CI=0.43-1.00] respectively) and were supported by an almost perfect Tetrachoric Correlation of 0.99 (p < 0.01). We anticipate to complete enrollment of subjects by the summer of 2022. Analysis of collected data is underway.

Conclusion

The strong to moderate association of MSUS with contrast-enhanced MRI, suggest that MSUS can provide an objective and accurate assessment of ankle, wrist and finger arthritis at the bedside. Further refinement and validation of these pediatric-specific MSUS scoring systems may support the use of MSUS as a clinical tool and outcome measure in JIA.

POS1385 INTERNATIONAL CONSENSUS FOR ULTRASOUND DEFINITIONS OF TENOSYNOVITIS IN JUVENILE IDIOPATHIC ARTHRITIS: RESULTS OF A DELPHI PROCESS

Background

Musculoskeletal Ultrasonography (US) is a suitable tool for the clinical assessment in juvenile idiopathic arthritis (JIA). Recently US definitions for normal components of pediatric joints and synovitis have been developed by the OMERACT US working group. Currently this group is working on development and validation of US definition for tenosynovitis as it is also an essential prerequisite for the reliable use of this technology in the pediatric age group.

Objectives

To produce consensus-based definitions for US tenosynovitis in JIA through a Delphi process.

Methods

We undertook a Delphi process on US-defined tenosynovitis in children that consisted of two steps. As a prior systematic literature review showed that US anatomy of the tendons is similar to adults, a Delphi questionnaire was written based on the consensual definitions developed for and used in adults with rheumatoid arthritis [1, 2]. The Delphi questionnaire was sent to rheumatologists and pediatricians who perform pediatric US examination, asking them to rate their level of agreement with each statement of US-defined tenosynovitis. Group agreement was considered if ≥80% of responders scored an item as either 4 or 5.

In the second step, the definitions were validated on 88 standardized US images displaying various degrees of tenosynovitis obtained from JIA patients at various ages. Tendons often involved in JIA were selected (foot and ankle tendons, hand and wrist tendons, bicep tendon.). US images of both normal and tenosynovitis elementary lesions were collected by the 18 experts participating in the OMERACT US task force on pediatric tenosynovitis. An agreement ≥70% was considered mandatory for accepting the definition as applicable in the rated image.

Results

The response rate was 75% (28 out of 37) from the first Delphi questionnaire. Strong group agreement (≥86%) was obtained for the US definitions tested. The response rate was 88.9% (16 out of 18) from the Web-exercise after four rounds. The final definitions were validated on still images for all tendons, except for the biceps tenosynovitis in the age group 2-4 years (the definitions of elementary lesions and the global definition of tenosynovitis) as no image was available for this location and age group. Despite not reaching group agreement after the second and the third round for the US-defined normal finger pulley in children aged 8 years and younger (roughly 68% and 69% respectively), it reached a score of 99.8% after the fourth round.

Conclusion

US definitions of tenosynovitis and its elementary components covering a wide pediatric age range were successfully developed through a Delphi questionnaire and validated in a web-based still images exercise. These results provide the basis for the standardized US assessment of tenosynovitis in clinical practice.

POS1303 METHOTREXATE RESPONSE IN PEDIATRIC NON-INFECTIOUS UVEITIS

Background

Children with chronic non-infectious uveitis (NIU) are at risk for sight-threatening complications. Methotrexate (MTX) is the preferred first-line systemic treatment. Initial therapeutic response takes 3-6 months to achieve NIU control, leading to prolonged glucocorticoid use. Moreover, at least 50-70% of children fail to fully respond and may accrue ocular damage while awaiting MTX response.

Objectives

To identify features of children with NIU that are associated with MTX failure.

Methods

We included children who started MTX monotherapy for NIU. We collected demographics, NIU features (type, location, & complications), ANA status, and clinical examination. We characterized children as MTX responders or non-responders. MTX responders are those whose NIU was controlled, defined by: 1) inactive graded by SUN criteria, 2) absence of new or worsening complications, and 3) requirement for ≤2 drops of prednisolone acetate and no oral glucocorticoids.

Results

Of 47 NIU children, 68% were MTX non-responders (Table 1), having a longer duration of NIU (Odds Ratio [OR]=1.28, [CI=1.03-1.8], p =0.023) and developing more ocular complications (OR=1.95 [CI=1.23-3.38], p=0.017), (ROC Area Under the Curve = 0.85). MTX non-responders were more likely to have anterior and/or posterior synechiae (p = 0.001), cataracts (p=0.015), and ocular hypertension (p=0.039). Treatment included adalimumab: 27, infliximab: 14, tocilizumab: 5, golimumab: 4, etanercept: 3, and abatacept: 2.

We performed a sub analysis of children with idiopathic chronic anterior NIU (CAU) and JIA-associated NIU that included children who failed MTX due to intolerance/toxicity (Figure 1). Using Cox proportional hazard regression, 8 idiopathic CAU failed MTX earlier than 38 JIA-associated NIU (HR 2.77, [CI-=1.06-7.27], p=0.039). Results were similar with the inclusion of other types of NIU (p=0.088) (e.g., HLA-B27, non-anterior idiopathic or with systemic disease).

Kaplan-Meier curve showing freedom from TNFi (mos) stratified by diagnosis

Conclusion

Two out of three children with NIU fail initial MTX monotherapy, exposing them to increased accrual of ocular complications prior to biologic starts. The risk for delay in starting tumor necrosis factor α inhibitors (TNFi) seems higher with CAU. Future studies will examine risk factors that predict MTX response in NIU.

Social determinants of health influence disease activity and functional disability in Polyarticular Juvenile Idiopathic Arthritis

BACKGROUND

Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry.

METHODS

In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months.

RESULTS

One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability.

CONCLUSION

High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

An action research to improve social health insurance coverage of Philippines’ informal sector

Background

PhilHealth, the social health insurance (SHI) agency of the Philippines, still does not sufficiently cover the informal sector workers (ISWs) - or the “missing middle”. Previous approaches had limited success. The impetus for finding solutions to protect the missing middle still remains.

Methods

A multi-component action research was done to address the complex social problem. Literature review and interviews were conducted to understand the nature of ISWs. National survey data was analyzed for factors affecting the ISWs' membership and retention in SHI. Findings were triangulated to construct evidence-based and context-rich marketing personas to understand PhilHealth's target clients. Using Human-Centered Design Thinking (HCDT), solutions that aim to address the low retention of ISWs in health insurance (HI) were proposed.

Results

The exact nature of ISWs is still unknown. Costly insurance premiums, poor knowledge of SHI, low perceived value of SHI, and inconvenient payment mechanisms contribute to low participation in SHI. Every additional 1000 PHP (∼20 USD) income increases odds of being an active member by 4%. Those who access private facilities are 2.8 times more likely to be active members. Those who perceive themselves to be sickly were 52% more likely to drop-out of the insurance. The results were fed into the HCDT process producing four prototypes: 1) solutions that explore partnership of PhilHealth with other organizations, 2) use of mobile application platforms for payment and member status updates, 3) automated algorithm to identify and calculate fair premiums, and 4) integration of money-saving strategies.

Conclusions

The government needs to step-up current efforts to extend health financial risk protection for the ISWs. PhilHealth can take advantage of the research results by testing the prototypes produced, and by adopting the HCDT process to improve their service and coverage for the informal sector.

Key messages

This government-funded project integrated principles of public health, epidemiology, health financing, participatory governance, and implementation research to address a complex social problem. The results provide a better understanding of the informal sector workers’ nature and needs with regards health insurance and can help PhilHealth improve coverage of informal sector workers.

OP0291 TOFACITINIB FOR THE TREATMENT OF POLYARTICULAR COURSE JUVENILE IDIOPATHIC ARTHRITIS: RESULTS OF A PHASE 3, RANDOMISED, DOUBLE-BLIND, PLACEBO-CONTROLLED WITHDRAWAL STUDY

Background:

Tofacitinib is an oral JAK inhibitor that is being investigated for JIA.

Objectives:

To assess tofacitinib efficacy and safety in JIA patients (pts).

Methods:

This was a Phase 3, randomised, double-blind (DB), placebo (PBO)-controlled withdrawal study in pts aged 2−<18 years with polyarticular course JIA (pcJIA), PsA or ERA (NCT02592434). In the 18-week open-label Part 1, pts received weight-based tofacitinib doses (5 mg BID or lower). Pts with ≥JIA ACR30 response at Week (W)18 were randomised 1:1 in the DB Part 2 (W18−44) to continue tofacitinib or switch to PBO. Primary endpoint: disease flare rate by W44. Key secondary endpoints: JIA ACR50/30/70 response rates; change from Part 2 baseline (Δ) in CHAQ-DI at W44. Other efficacy endpoints: time to disease flare in Part 2; JADAS27-CRP in Parts 1 and 2. PsA/ERA pts were excluded from these efficacy analyses. Safety was evaluated in all pts up to W44.

Results:

225 enrolled pts with pcJIA (n=184), PsA (n=20) or ERA (n=21) received tofacitinib in Part 1. At W18, 173/225 (76.9%) pts entered Part 2 (pcJIA n=142, PsA n=15, ERA n=16). In pcJIA pts, disease flare rate in Part 2 was significantly lower with tofacitinib vs PBO by W44 (p=0.0031; Fig 1a). JIA ACR50/30/70 response rates (Fig 1b) and ΔCHAQ-DI (Fig 1c) at W44, and time to disease flare in Part 2 (Fig 2a), were improved with tofacitinib vs PBO. Tofacitinib reduced JADAS27-CRP in Part 1; this effect was sustained in Part 2 (Fig 2b). Overall, safety was similar with tofacitinib or PBO (Table): 77.3% and 74.1% had adverse events (AEs); 1.1% and 2.4% had serious AEs. In Part 1, 2 pts had herpes zoster (non-serious) and 3 pts had serious infections (SIs). In Part 2, SIs occurred in 1 tofacitinib pt and 1 PBO pt. No pts died.

Conclusion:

In pcJIA pts, tofacitinib vs PBO resulted in significantly fewer disease flares, and improved time to flare, disease activity and physical functioning. Tofacitinib safety was consistent with that in RA pts.

Fecal calprotectin predicts the clinical course of acute severe ulcerative colitis

OBJECTIVES

Calprotectin is a granulocyte neutrophil-predominant cytosolic protein. Fecal concentrations are elevated in intestinal inflammation and may predict relapse in quiescent inflammatory bowel disease. We aim to investigate fecal calprotectin (FC) as a biomarker in predicting the clinical course of acute severe ulcerative colitis (ASUC).

METHODS

In 90 patients with ASUC requiring intensive in-patient medical therapy (January 2005-September 2007), we investigated the discriminant ability of FC to predict colectomy and corticosteroid and infliximab nonresponse. All patients received parenteral corticosteroids as first-line treatment; 21 (23.3%) were also treated with infliximab (5 mg/kg), after failure of corticosteroid therapy.

RESULTS

Of 90 patients, 31 (34.4%) required colectomy, including 11 (52.4%) of those treated with infliximab. Overall FC was high (1,020.0 microg/g interquartile range: 601.5-1,617.5). FC was significantly higher in patients requiring colectomy (1,200.0 vs. 887.0; P=0.04), with a trend toward significance when comparing corticosteroid nonresponders and responders (1,100.0 vs. 863.5; P=0.08), as well as between infliximab nonresponders and responders (1,795.0 vs. 920.5; P=0.06). Receiver-operator characteristic curve analysis yielded an area under the curve of 0.65 to predict colectomy (P=0.04), with a maximum likelihood ratio of 9.23, specificity 97.4%, and sensitivity 24.0% at a cutoff point of 1,922.5 microg/g. Kaplan-Meier analyses showed that using 1,922.5 microg/g over a median follow-up of 1.10 years, 87% of patients will need subsequent colectomy.

CONCLUSIONS

This is the first data set to demonstrate that FC levels are dramatically elevated in severe UC. These data raise the possibility that this biomarker can predict response to first or second-line medical therapy in this setting.

The use of adalimumab in the management of refractory Crohn's disease

BACKGROUND

Adalimumab is a humanized monoclonal antibody targeting tumour necrosis factor-alpha. Recent clinical trials have demonstrated its efficacy in Crohn's disease; however, experience in clinical practice remains limited.

AIM

To investigate the efficacy and safety of adalimumab in the clinical setting.

METHODS

The clinical outcomes of patients with medically refractory Crohn's disease treated with adalimumab in the Western General Hospital Edinburgh, over a 3-year period (2003-2006), were studied.

RESULTS

Twenty-two (14 females; age at therapy: 32.6 years) patients were treated using an 80/40 mg induction regimen followed by fortnightly 40 mg treatment. All had proven refractory/intolerant to corticosteroids and immunosuppression. Twenty patients had had previous infliximab infusions - of these eight (36%), six (27%), three (14%) had previous infusion reactions, no response and lost response to infliximab, respectively. Over a period of 1.0 years (IQR: 0.62-2.5), Kaplan-Meier analyses showed that 68% (seven nonresponders) were in clinical remission and 67% (five surgery - discounting oral CD) avoided further surgery for active disease. 59% required dose escalation to 40 mg weekly (0.55 years; IQR: 0.22-1.4). Three (50%) primary nonresponders to infliximab achieved remission. Two patients developed serious infective complications and one patient developed lung cancer.

CONCLUSIONS

Adalimumab is efficacious in refractory Crohn's disease, with benefit observed in infliximab primary nonresponders. However, many patients require escalation of dosing regimen.

Relationships between age and symptom severity among women seeking medical treatment for premenstrual symptoms

Age at the time of seeking treatment for premenstrual symptoms (PMS) was examined in a sample of 332 women who reported severe distress and met criteria for Late Luteal Phase Dysphoric Disorder (LLPDD). The mean age of the sample was 33.1 (+/- 5.3) years. Severity of symptoms decreased with age and was not associated with the duration of symptoms. Depression-related factors were associated with the severity of PMS, and together with the duration of symptoms, were the best discriminators between the younger (ages 20-35) and older (ages 36-44) women in this sample. These data suggest that the years of the late twenties through mid-thirties are the most vulnerable time for distressing PMS and fail to support the clinical premise that PMS worsens with age until menopause. Further longitudinal study should be conducted to confirm and extend these findings.

Mental status of residents in old people's homes

As part of an intensive survey of institutionalized elderly in 5 non-government homes for the aged in Singapore, mental health assessment of the residents was carried out systematically. Among 359 respondents, 30.1% often felt sad or cried often. Sleep disturbances affected 47.7% of the total respondents. Females were more prone to both depression and insomnia even after controlling for age difference; about 50% of the females aged 60-74 years and 70% of the females aged 75 years and above had frequently experienced these problems. A review of the literature on mental health and suicidal behaviour among the elderly is also presented.
