The diagnosis of Neuropsychiatric systemic lupus erythematosus disease (NPSLE) is challenging. The Automated Neuropsychological Assessment Metrics (ANAM) has been shown to be an accessible and promising tool for evaluating possible NPSLE in adult and childhood lupus. In this review, we present information about the development and use of Ped-ANAM; the benefit of using Ped-ANAM in children with and without NPSLE in the assessment and follow up of their disease condition; and the correlation of Ped-ANAM to imaging studies such as magnetic resonance imaging (MRI)...

BACKGROUND: Diffuse alveolar hemorrhage (DAH) is a devastating clinical syndrome characterized by a falling hematocrit, respiratory insufficiency, and radiographic evidence of pulmonary infiltrates. Literature regarding management of DAH in childhood-onset SLE (cSLE) is limited. METHODS: We reviewed the presentation, management, and outcome of DAH in a pediatric tertiary medical center with one of the largest cSLE cohorts in North America. During a 10 year period 7 of 410 children with cSLE had DAH...

BACKGROUND: Neurological complications, especially encephalopathy and seizures, are commonly seen in bone marrow transplant patients. Infections, chemotoxicity, graft versus host disease, or secondary central nervous system malignancies are the most common underlying etiologies. There is increased awareness that autoimmune encephalitis may cause neurological dysfunction in immunocompetent children. The potential role of such a mechanism in children undergoing bone marrow transplantation is unknown...

BACKGROUND/AIMS: There is a critical need for more noninvasive biomarkers to identify nephritis in patients with systemic lupus erythematosus (SLE). Recent studies in a model mouse and an adult SLE patient cohort suggest that anti-basement membrane antibody levels correlate well with lupus activity and kidney injury. The purpose of this study was to assess the anti-basement membrane reactivity in pediatric SLE (pSLE) patients with or without nephritis. METHODS: Auto-antibodies to basement membrane antigens were assessed using an anti-matrigel ELISA...

OBJECTIVE: To develop and initially validate a global cognitive performance score (CPS) for the Pediatric Automated Neuropsychological Assessment Metrics (PedANAM) to serve as a screening tool of cognition in childhood lupus. METHODS: Patients (n = 166) completed the 9 subtests of the PedANAM battery, each of which provides 3 principal performance parameters (accuracy, mean reaction time for correct responses, and throughput). Cognitive ability was measured by formal neurocognitive testing or estimated by the Pediatric Perceived Cognitive Function Questionnaire-43 to determine the presence or absence of neurocognitive dysfunction (NCD)...

OBJECTIVE: To determine perceived barriers to and facilitators of a career in rheumatology research, examine factors leading rheumatologists to leave an academic research career, and solicit ways to best support young physician-scientists. METHODS: A web-based survey was conducted among the domestic American College of Rheumatology (ACR) membership from January through March 2014. Inclusion criteria were ACR membership and an available e-mail address. Non-rheumatologists were excluded...

BACKGROUND/PURPOSE: In 1998, Sorof et al. reported 28% of 60 pediatric SLE patients had class V lesions on their first biopsy and 37% had class V lesions on their most recent biopsy. Although 19% of patients with LN transformed from other classes to class V, there were no patients with repeat biopsies who showed complete resolution of their class V lesions. The prognosis of the patients with class V LN was better than those with non-class V LN (only 5% vs. 21% developed renal dysfunction or died)...

BACKGROUND/PURPOSE: Children with SLE (cSLE) can experience neuropsychiatric SLE (NPSLE), commonly manifesting as neurocognitive dysfunction which can interfere with normal development. Formal neurocognitive testing (FNCT) is the most accepted test for diagnosing neurocognitive deficits (NCD). Access to it is limited and costly, and it is time-consuming. The Pediatric Automated Neurophysiological Assessments Metrics (PedANAM) is a computerized battery of 10 subtests measuring various aspects of cognitive ability...

BACKGROUND/PURPOSE: In pediatric rheumatology, the small size of many academic programs translates into limited mentoring options for early career physicians. To address this "mentorship gap," in 2011 the American College of Rheumatology (ACR) and the Childhood Arthritis and Rheumatology Research Alliance (CARRA) joined together to develop AMIGO, the ACR/CARRA Mentoring Interest Group, that now includes greater than half of pediatric rheumatology fellows and junior faculty in the US and Canada...

BACKGROUND/PURPOSE: Comparisons of pediatric ANCA-associated vasculitis subtypes (AAV) are limited by the paucity of reported cases, standardized definitions, and overlapping classification criteria. Published work from ARChiVe (A Registry for Childhood Vasculitis) demonstrated modifications of validated classification algorithms applied to pediatric patients with AAV can classify each patient to mutually exclusive diagnostic categories. We compared presenting features of children with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) classified according to this methodology...

BACKGROUND/PURPOSE: Pulmonary hemorrhage (PH) is a rare and devastating manifestation of SLE, occurring in 1-5% of adult cohorts with mortality rates ranging from 70%-90%. The majority of PH reported in SLE refers to the adult population, and there is a paucity of data in pediatrics. Therefore, we describe our experience with PH in pediatric SLE, outlining disease presentation, treatment, and outcomes. METHODS: We reviewed records of pediatric SLE patients who presented with pulmonary involvement diagnosed between January 2000 and August 2010...

BACKGROUND/PURPOSE: Males represent 4-22% of all SLE patients, but it is unclear if gender should influence management. A number of studies of mostly adult patients suggest genetic, hormonal and environmental aspects of gender differences contribute to differences in presentation, clinical course and outcome, including a positive association between male gender and nephritis and a negative association with disease activity and outcome. While differences may exist, these findings are supported by limited evidence, particularly for children and adolescents with SLE...

BACKGROUND: Movement disorders are frequent but difficult to characterize in patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. METHODS: The phenomenology of movement disorders was characterized after a detailed examination of children with anti-NMDAR-encephalitis. RESULTS: We studied 9 children (5 females), ages 3-14 years, with confirmed anti-NMDAR-encephalitis. All patients presented with at least 1 movement disorder, including chorea (n=4), stereotypic movements (n=4), ataxia (n=3), limb dystonia (n=2), limb myorhythmia (n=2), oromandibular dystonia (n=2), facial myorhythmia, blepharospasm, opisthotonus, athetosis, and tremor (n=1, each)...

Polyarteritis nodosa is a systemic necrotizing vasculitis involving medium-sized muscular arteries. Polyneuropathy is the only neurologic manifestation included in the pediatric classification schema. Central nervous system manifestations include infarction, hemorrhage, and encephalitis. We report on a 13-year-old female whose initial presentation of polyarteritis nodosa included hypertension, seizures, and neuroimaging findings of vasogenic edema and posterior reversible encephalopathy syndrome. Posterior reversible encephalopathy syndrome has been reported in association with renal disease, transplantation, autoimmunity, and cytotoxic medications...
