Abstract
Mammography screening rates are typically lower in those with less economic advantage (EA). This study, conducted at an integrated health care system covering a mixed rurality population, assessed the ability of interventions (text messages linking to a Web microsite, digital health care workers, and a community health fair) to affect mammography screening rates and disparity in those rates among different EA populations. Payor type served as a proxy for greater (commercially insured) versus lower (Medicaid insured) EA. 4,342 subjects were included across the preintervention ("Pre") and postintervention ("Post") periods. Interventions were prospectively applied to all Medicaid subjects and randomly selected commercial subjects. Applying interventions only to lower EA subjects reversed the screening rate disparity (2.6% Pre vs. -3.7% Post, odds ratio [OR] 2.4 P < 0.01). When intervention arms ("Least," "More," "Most") were equally applied, screening rates in both EA groups significantly increased in the More arm (Medicaid OR = 2.04 P = 0.04, Commercial OR = 3.08 P < 0.01) and Most arm (Medicaid OR 2.57 P < 0.01, Commercial OR 2.33 P < 0.01), but not in the Least (text-only) arm (Medicaid OR 1.83 P = 0.11, Commercial OR 1.72 P = 0.09), although this text-only arm was inadequately powered to detect a difference. In summary, targeting interventions to those with lower EA reversed screening rate disparities, text messaging combined with other interventions improved screening rates in both groups, and future research is needed to determine whether interventions can simultaneously improve screening rates for all without worsening the disparity.

Abstract
Geographically dispersed patients, inconsistent treatment tracking, and limited infrastructure slow research for many orphan diseases. We assess the feasibility of a patient-powered study design to overcome these challenges for Castleman disease, a rare hematologic disorder. Here, we report initial results from the ACCELERATE natural history registry. ACCELERATE includes a traditional physician-reported arm and a patient-powered arm, which enables patients to directly contribute medical data and biospecimens. This study design enables successful enrollment, with the 5-year minimum enrollment goal being met in 2 years. A median of 683 clinical, laboratory, and imaging data elements are captured per patient in the patient-powered arm compared with 37 in the physician-reported arm. These data reveal subgrouping characteristics, identify off-label treatments, support treatment guidelines, and are used in 17 clinical and translational studies. This feasibility study demonstrates that the direct-to-patient design is effective for collecting natural history data and biospecimens, tracking therapies, and providing critical research infrastructure.

Abstract
8548 Background: Castleman disease (CD) describes a group of lymphoproliferative disorders that share characteristic histopathology. Unicentric CD (UCD) and idiopathic multicentric CD (iMCD) are differentiated by the number of enlarged lymph node (LN) regions: UCD involves 1 region and iMCD involves > 1 region. UCD typically has mild or no symptoms whereas iMCD requires abnormal labs and symptoms for diagnosis and can progress to life-threatening multi-organ failure. Review of an international natural history registry of CD revealed patients across a broad spectrum with regards to number of enlarged LN regions and disease severity. We hypothesize that there is a positive correlation between disease activity and the number of enlarged LNs and that the spectrum of CD is more complex than a binary UCD-iMCD dichotomy. Methods: Herein, enrolled UCD and iMCD patients whose diagnosis was confirmed by an expert-panel were selected for analysis (N = 81). A standardized disease activity score (scale 0-1) was computed for each patient using available diagnostic values of C-reactive protein, hemoglobin, and albumin (CHA score). Results: We looked at the association between number of enlarged LNs and CHA and found a significant positive correlation (R = 0.65, p < 0.0001). Given this, we divided the cohort into groups of mild, moderate, and extensive lymphadenopathy according to the number of regions of enlarged LNs at the time of diagnosis: group 1 (1 enlarged LN region); group 2 (2-4 enlarged LN regions); and group 3 (≥5 enlarged LN regions). We identified 20 patients in group 1, 19 in group 2, and 42 in group 3 with no statistical differences in sex, race, or age at diagnosis. Histopathological subtype differed significantly among groups. Group 1 was 89% hyaline vascular (HV)/ hypervascular (HpV) and 11% mixed (Mx); group 2 was 74% HV/HpV, 21% Mx, and 5% plasmacytic (Pl); and group 3 was 64% HV/HpV, 32% Mx, and 5% Pl. We then looked at CHA score in these groups and found that group 3 patients have a significantly greater CHA score (median [IQR]: 0.46 [0.49]) than both group 2 (0.08 [0.14]) and group 1 (0.0 [0.10]) (adjusted p < 0.001 for both) while there was no difference between groups 1 and 2. Conclusions: These results suggest that disease severity is positively associated with the number of enlarged LNs. The different proportions of histopathological subtypes between the three groups could indicate different pathologic mechanisms are involved. Further work is needed to determine if patients with a few enlarged LNs exhibit disease more closely to UCD or iMCD and to understand long-term outcomes for these patients.

Abstract
Idiopathic multicentric Castleman disease (iMCD) is a rare and poorly understood hematologic disorder characterized by lymphadenopathy, systemic inflammation, cytopenias, and life-threatening multiorgan dysfunction. Interleukin-6 (IL-6) inhibition effectively treats approximately one-third of patients. Limited options exist for nonresponders, because the etiology, dysregulated cell types, and signaling pathways are unknown. We previously reported 3 anti-IL-6 nonresponders with increased mTOR activation who responded to mTOR inhibition with sirolimus. We investigated mTOR signaling in tissue and serum proteomes from iMCD patients and controls. mTOR activation was increased in the interfollicular space of iMCD lymph nodes (N = 26) compared with control lymph nodes by immunohistochemistry (IHC) for pS6, p4EBP1, and p70S6K, known effectors and readouts of mTORC1 activation. IHC for pS6 also revealed increased mTOR activation in iMCD compared with Hodgkin lymphoma, systemic lupus erythematosus, and reactive lymph nodes, suggesting that the mTOR activation in iMCD is not just a product of lymphoproliferation/inflammatory lymphadenopathy. Further, the degree of mTOR activation in iMCD was comparable to autoimmune lymphoproliferative syndrome, a disease driven by mTOR hyperactivation that responds to sirolimus treatment. Gene set enrichment analysis of serum proteomic data from iMCD patients (n = 88) and controls (n = 42) showed significantly enriched mTORC1 signaling. Finally, functional studies revealed increased baseline mTOR pathway activation in peripheral monocytes and T cells from iMCD remission samples compared with healthy controls. IL-6 stimulation augmented mTOR activation in iMCD patients, which was abrogated with JAK1/2 inhibition. These findings support mTOR activation as a novel therapeutic target for iMCD, which is being investigated through a trial of sirolimus (NCT03933904).
