Background: There is a pressing need for robust longitudinal cohort studies in the modern treatment era of multiple sclerosis. Objective: Build a multiple sclerosis (MS) cohort repository to capture the variability of disability accumulation, as well as provide the depth of characterization (clinical, radiologic, genetic, biospecimens) required to adequately model and ultimately predict a patient’s course. Methods: Serially Unified Multicenter Multiple Sclerosis Investigation (SUMMIT) is an international multi-center, prospectively enrolled cohort with over a decade of comprehensive follow-up on more than 1000 patients from two large North American academic MS Centers (Brigham and Women’s Hospital (Comprehensive Longitudinal Investigation of Multiple Sclerosis at the Brigham and Women’s Hospital (CLIMB; BWH)) and University of California, San Francisco (Expression/genomics, Proteomics, Imaging, and Clinical (EPIC))). It is bringing online more than 2500 patients from additional international MS Centers (Basel (Universitätsspital Basel (UHB)), VU University Medical Center MS Center Amsterdam (MSCA), Multiple Sclerosis Center of Catalonia-Vall d’Hebron Hospital (Barcelona clinically isolated syndrome (CIS) cohort), and American University of Beirut Medical Center (AUBMC-Multiple Sclerosis Interdisciplinary Research (AMIR)). Results and conclusion: We provide evidence for harmonization of two of the initial cohorts in terms of the characterization of demographics, disease, and treatment-related variables; demonstrate several proof-of-principle analyses examining genetic and radiologic predictors of disease progression; and discuss the steps involved in expanding SUMMIT into a repository accessible to the broader scientific community.

Abstract POST TRANSPLANT BRENTUXIMAB MAINTENANCE APPEARS MORE EFFECTIVE THAN POST TRANSPLANT SALVAGE BRENTUXIMAB FOR RELAPSED /REFRACTORY HODGKIN LYMPHOMA Amanda Chidiac1, Radwan Massoud 1, Mohamad Haidar1, Elie Fares1, Ali Bazarbachi1 and Jean El Cheikh1 1Bone Marrow Transplantation Program, American University of Beirut Medical Center, Beirut, Lebanon Keywords: Hodgkin Lymphoma, Relapsed/Refractory, Brentuximab. Context: Brentuximab Vedotin (BV) is a chimeric anti CD30 IgG1 antibody, conjugated to synthetic antitubulin momomethyl auristatin. BV is approved for the treatment of classical HL in relapse either after autologous stem cell transplantation (ASCT) or after two lines of combination chemotherapy in transplant ineligible patients. The AETHERA trial revealed increased PFS when BV is used as maintenance therapy after ASCT. Objective: Compare the effectiveness of BV as maintenance or salvage therapy after ASCT for relapsed/refractory (R/R) HL. Design: A retrospective analysis conducted on patients with R/R HL treated with BV after ASCT either as maintenance or salvage therapy. Analysis after a median follow up of 12 months is reported. Setting: The study was conducted in a single institution; American University of Beirut Medical Center (AUBMC) after IRB approval. Patients: The study included 15 adult patients with R/R HL treated with BV with the following indications: á Maintenance therapy after ASCT in high risk patients á Salvage therapy for relapse after ASCT or allo-SCT Intervention: BV at 1.8mg/kg IV every 4 weeks for the above indications. Main outcome measures: response rate (RR), overall survival (OS) and progression free survival (PFS). Results: Nine high-risk patients (60%) received 4 cycles of BV as maintenance therapy post ASCT. Six additional patients (40%) in relapse after ASCT (n=5) or after allo-SCT (n=1) received BV as salvage therapy for an average of 4 cycles (range 3-21). Patients characteristics are listed on Table 1. RR was 33% in 6 patients who received BV as salvage post SCT. Two patients proceeded with allo-SCT in the salvage group. After a median follow up of 9 months, only 2 patients (22%) in the maintenance group progressed and all patients are still alive. Conversely, in the salvage group, 4 patients (67%) progressed and 1 patient developed secondary AML and died. Conclusion: BV therapy showed an efficacy only as maintenance treatment after auto-SCT but was less successful when used as post-transplant salvage in R/R HL. Four cycles of maintenance may suffice. Prospective trials with larger samples are warranted to support these findings. Disclosures No relevant conflicts of interest to declare.

Objectives. The aim of this study is to demonstrate the various imaging appearances of stromal fibrosis on mammography, ultrasound, and magnetic resonance imaging (MRI). Material and Methods. This study included 75 female patients who presented to the American University of Beirut Medical Center between January 2010 and October 2015 for breast imaging. 66 (88%) patients obtained a mammogram, 71 (95%) had an ultrasound, and 6 (8%) had an MRI. Patients included had stromal fibrosis proven on biopsy. Results. The most common finding on mammogram was calcifications which was present in 14 (21%) patients, while on ultrasound it was a mass which was present in 61 (86%) patients. A mass was detected on MRI in 2 (33.5%) patients. Most lesions detected had benign findings such as masses with circumscribed margins. We had a follow-up for 53 (71%) patients with an average follow-up interval of 28.5 months (range: 5 – 70). Increase in size of the index lesion was noted in only 2 patients; upon rebiopsy, pathology results read stromal fibrosis for one lesion and fibroadenoma for the other. The remaining lesions were either stable or decreased in size. The higher detection rate of a mass on ultrasound was statistically significant (p<0.001) in comparison to that of mammography. Conclusion. Stromal fibrosis can have various presentations on imaging from benign to suspicious for malignancy features. In the case of accurate targeted biopsy, when stromal fibrosis is diagnosed, the result can be considered concordant. Therefore, such lesions can be followed up by imaging to document stability and confirm benignity.

AbstractFollowing an outbreak of varicella, 18% of a group of 174 young female Filipino nurses ranging in age from 20 to 25 years and working at the American University of Beirut Medical Center (AUMC) were found susceptible to the varicella-zoster virus; as compared to 3% of a matched group of 133 of their Lebanese colleagues. The level of antibody was determined by the Enzyme Linked Immunosorbent Assay (ELISA). Those susceptible were assigned duties in low-risk areas to varicella-zoster in the hospital.
