Abstract Objective To describe the first reported case of pneumatosis intestinalis (PI) in a pediatric patient with granulomatosis with polyangiitis (GPA) and multiple other risk factors and review ...the literature for PI in adult and pediatric rheumatologic conditions. Methods A PubMed search was completed using the search phrase “pneumatosis intestinalis.” Searches were limited to humans and the English language, and remaining articles involving patients with rheumatologic diagnoses were identified and included in our discussion. Results This is the first reported of case of PI in a patient with underlying GPA or antineutrophil cytoplasmic antibody-associated vasculitides. Out of 90 previously reported cases of PI in patients with rheumatologic conditions, 79 cases were in adults and 11 in children. There were 30 patients with systemic sclerosis, 18 with MCTD/overlap syndrome, 18 with dermatomyositis or polymyositis, 16 with SLE, and 8 with other diagnoses. Overall, 81% of the patients were on corticosteroids or other immunosuppressants prior to development of PI. The most common presenting symptom was abdominal pain, and 51% of patients had associated pneumoperitoneum. Conclusions PI can be associated with a broad spectrum of rheumatic diseases, including GPA, and should be included in the differential diagnosis of patients with rheumatologic conditions and nonspecific gastrointestinal symptoms.

Early juvenile idiopathic arthritis (JIA) is important to recognize as timely diagnosis and treatment improves prognosis. It is a misconception that complications of JIA arise only from long-standing ...disease and that children will outgrow it. Early aggressive treatment is the paradigm as early disease activity has long-term consequences. There are predictors of persistent disease and joint erosions that may identify patients at higher risk. Control of disease activity within the first 6 months of onset confers improved clinical course and outcomes. The treatment perspective is thus one of early aggressive treatment for induction of disease control and ultimately remission.
Progress in the diagnosis and management of pediatric rheumatic disease has improved complications from underlying disease and the survival of children. However, as a consequence, infection has now ...become one of the leading causes of morbidity and mortality. Differentiating between infections and disease flares in children with rheumatic conditions can often pose diagnostic quandaries. Children with rheumatic diseases are at risk of infection, not only because of the use of immune-modulating medications but also because of underlying immune dysfunction associated with their disease. Although bacterial infections are the most common, any organism can potentially be a causative agent and, at times, more invasive measures of diagnosis, for example bronchoscopy and tissue biopsies may be necessary. Maintaining a high index of suspicion of infection with prompt diagnosis and treatment are important to further improve patient outcomes.
Kawasaki disease (KD) is a self-limited systemic vasculitis, most often occurring in children 1⁻5 years old. It has a 2% recurrence rate and is associated with coronary aneurysms (CA), which can ...develop within two weeks of onset. A 25% increased risk is noted in patients who are recalcitrant to treatment. We describe a patient with recurrence of KD three times, approximately four years apart. A 10-year-old female with two previous episodes of KD, at 11 months and five years of age), in which she met five out of five criteria for KD and had no coronary involvement, presented with 15 days of fever, conjunctivitis and mucocutaneous changes. Infectious work-up was negative, and she was diagnosed with incomplete KD meeting three out of five criteria. An echocardiogram (ECHO) on day 12 revealed dilation of the right coronary artery (RCA) and left coronary artery (LCA). Treatment with intravenous immunoglobulin (IVIG) and high-dose aspirin was started at an outside hospital. After transfer, serial ECHOs showed evolving coronary aneurysms, left anterior descending (LAD) z-score + 8.2 and RCA z-score + 4.0. She received 10 mg/kg infliximab (day 18) and began clopidogrel. A cardiac MRI (day 20) demonstrated progression of the LAD aneurysm, with a z-score + 13, and warfarin was started. To our knowledge, this is the first report of recurrent KD occurring three times at ~5 year intervals.
We present the case of a 16-year-old patient with systemic lupus erythematosus who presented with altered mental status and regressive behaviour. She was worked up and empirically treated for common ...and opportunistic infectious agents. All work-up was negative and after an extensive course of antibiotics she was treated for neuropsychiatric lupus with cytoxan. She initially responded, but this was short-lived and she eventually became comatose and passed away. On brain biopsy she was found to have numerous trophozoites with round nucleus, prominent nucleolus and thin nuclear membrane. Methenamine silver stain showed encysted amoeba, corresponding with a diagnosis of acanthamoeba meningoencephalitis. Making the diagnosis of acanthamoeba meningoencephalitis requires a high degree of suspicion. Specific serum antibodies may not be a reliable measure in immunocompromised patients and trophozoites in CSF can be confused with monocytes. Brain biopsy may be required to make a definitive diagnosis. It is important for clinicians treating immunocompromised patients to keep this agent in mind in an immunocompromised patient with neurological manifestations. Acanthamoeba infections have only been reported in a small handful of patients and, to our knowledge, this is the first reported case in the United States.

An internal database and medical records were reviewed for demographics, diagnoses, treatments, organ dysfunction, interventions, infections, and outcomes. Standardized mortality ratio was calculated based on Pediatric Risk of Mortality III estimated mortality. Factors associated with mortality were identified by univariate analyses.Ninety patients with 122 total admissions were identified. The majority of patients were Hispanic (63%), female (73%), and had systemic lupus erythematosus (62%). Pediatric rheumatic disease-related complications (50%) were the most common reason for admission; 32% of admissions involved multiorgan dysfunction. Eighteen admissions (15%) resulted in mortality. Deaths were most commonly attributed to combined infection and active rheumatic disease (50%), infection only (22%), rheumatic disease only (11%), or other causes (17%). In 30 (25%) admissions, a new rheumatologic diagnosis was established. Standardized mortality ratio was 0.72 (95% confidence interval 0.38-1.25) for pediatric rheumatic disease patients compared to 0.87 (95% confidence interval 0.79-0.96) for all pediatric intensive care unit patients. Factors associated with mortality included use of mechanical ventilation, vasopressors, and renal replacement (continuous venovenous hemodialysis) (all p < .05).
Pediatric rheumatic disease-related complications were the principal cause of pediatric intensive care unit admission. Deaths occurred most often from severe infections in patients with active rheumatic disease. Pediatric rheumatology patients admitted to the pediatric intensive care unit had outcomes similar to the global pediatric intensive care unit population when adjusted for severity of illness.
Treatment of children and adolescents with juvenile idiopathic arthritis and other pediatric rheumatic diseases has evolved. Where once there was only a limited arsenal of medications, with ...significant side effects and inadequate efficacy, today, with an increased understanding of the pathogenesis of these diseases, there is a wider variety of more targeted and effective treatments. TNF-α is a cytokine involved in a number of inflammatory pathways in pediatric rheumatic diseases. The emergence of biologic modifiers that target TNF-α has been pivotal in providing the ability to deliver early and aggressive treatment. Adalimumab, a recombinant monoclonal antibody to TNF-α, is an important therapeutic option, which affords children and adolescents with chronic illnesses an improved quality of life.
ObjectivesTo evaluate the long-term efficacy and safety of canakinumab to treat patients with colchicine-resistant familial Mediterranean fever (crFMF) during Epoch 4 (weeks 41 to 113) of the CLUSTER ...study.MethodsPatients received open-label canakinumab 150 or 300 mg, every 4 or 8 weeks during a 72-week period. We evaluated disease activity every 8 weeks using the physician global assessment (PGA) of disease activity, counting the number of flares, and measuring concentrations of C reactive protein (CRP) and serum amyloid A (SAA). Safety was studied by determination and classification of observed adverse events (AEs). We analysed safety and efficacy separately in two subgroups of patients receiving a cumulative dose of less than 2700 mg, or equal or more than 2700 mg.ResultsOf the 61 patients that started the CLUSTER study, 60 entered Epoch 4 and 57 completed it. During the 72-week period, 35/60 (58.3%) patients experienced no flares, and 23/60 (38.3%) had one flare, as compared with a median of 17.5 flares per year reported at baseline. PGA scores indicated no disease activity for the majority of patients throughout the study. Median CRP concentrations were always lower than 10 mg/L, while median SAA concentrations remained over the limit of normal (10 mg/L) but under the 30 mg/L threshold. No new or unexpected AEs were reported.ConclusioncrFMF patients treated with canakinumab during 72 weeks experienced a minimal incidence of flares and good control of clinical disease activity, with no new safety concerns reported.
Tofacitinib is an oral Janus kinase inhibitor. This trial assessed the efficacy and safety of tofacitinib versus placebo in patients with polyarticular course juvenile idiopathic arthritis (JIA).
...This double-blind, withdrawal phase 3 trial enrolled patients with polyarticular course JIA (extended oligoarthritis, rheumatoid factor-positive or rheumatoid factor-negative polyarthritis, or systemic JIA without active systemic features) aged 2 years to younger than 18 years, and was done at 64 centres of the Paediatric Rheumatology International Trials Organisation and Pediatric Rheumatology Collaborative Study Group networks in 14 countries. Patients with psoriatic arthritis or enthesitis-related arthritis were enrolled for exploratory endpoints. During part 1 of the study, patients received oral open-label tofacitinib (weight-based doses; 5 mg twice daily or lower) for 18 weeks. Patients achieving at least JIA/American College of Rheumatology 30 response were randomly assigned (1:1) using an Interactive Response Technology system to continue tofacitinib or switch to placebo in part 2 of the study for 26 weeks. The primary endpoint was JIA flare rate by week 44 in part 2 in patients with polyarticular course JIA; the intention-to-treat principle was applied. Safety was evaluated throughout part 1 and part 2 of the study in all patients who received one dose or more of study medication. This trial is registered with ClinicalTrials.gov, NCT02592434.
Between June 10, 2016, and May 16, 2019, of 225 patients enrolled, 184 (82%) patients had polyarticular course JIA, 20 (9%) had psoriatic arthritis, and 21 (9%) had enthesitis-related arthritis. 147 (65%) of 225 patients received concomitant methotrexate. In part 2, 142 patients with polyarticular course JIA were assigned to tofacitinib (n=72) or placebo (n=70). Flare rate by week 44 was significantly lower with tofacitinib (21 29% of 72 patients) than with placebo (37 53% of 70 patients; hazard ratio 0·46, 95% CI 0·27–0·79; p=0·0031). In part 2 of the study, adverse events occurred in 68 (77%) of 88 patients receiving tofacitinib and 63 (74%) of 85 in the placebo group. Serious adverse events occurred in one (1%) and two (2%), respectively. In the entire tofacitinib exposure period, 107 (48%) of 225 patients had infections or infestations. There were no deaths during this study.
The results of this pivotal trial show that tofacitinib is an effective treatment in patients with polyarticular course JIA. New oral therapies are particularly relevant for children and adolescents, who might prefer to avoid injections.

Introduction
Lupus nephritis (LN) in pediatric systemic lupus erythematosus (pSLE) requires treatment with corticosteroids (CS) and mycophenolate mofetil (MMF) or cyclophosphamide (CYC). However, ...some patients fail standard therapy leaving physicians with few options. Although two recent phase II/III randomized controlled trials using abatacept (ABA) with and without MMF in adult SLE did not meet their endpoints, we examined if this combination therapy may have a therapeutic benefit in pSLE patients with refractory class IV and V LN.
Methods
We performed a retrospective chart analysis of five pSLE patients with class IV and V LN. All patients were treated with ABA + MMF after previous failure to CYC and MMF. CS doses and SLE Disease Activity Index (SLEDAI) score were assessed at diagnosis and after 12 and 24 weeks of each treatment.
Results
Patient age at diagnosis was 9–15 years (mean 12.6 ± 2.3). Average disease duration before initiation of ABA + MMF therapy was 22–97 months (mo) (mean 52.8 ± 30.8). Treatment with ABA + MMF resulted in an improvement in SLEDAI score and reduction in CS dose by 12 weeks in all five patients. One patient achieved complete remission and three patients were weaned off steroids after 7–20 mo (mean 13 ± 6.5). Repeated measures analysis of variance showed significant change from SLEDAI at time of diagnosis (baseline) over 24 weeks of treatment with CYC (
P
= 0.0013) and with ABA + MMF (
P
< 0.0001). Paired comparison to baseline SLEDAI scores showed some decrease after 12 weeks of treatment with MMF monotherapy (
P
= 0.0520).
Conclusion
The data suggest that combination therapy with ABA + MMF may be an alternative option in refractory pSLE nephritis. Additional studies are needed in pSLE to further assess the efficacy of this combination treatment.
