    [VIRTUAL] Autologous Hematopoietic Stem Cell Transplantation in Multiple Sclerosis (aHSCT-in-MS): The Zurich Experience 24 Months after Approval () -  Aug 16, 2020 - Abstract #MSDC2020MSDC_387;    
    Conditioning high-dose chemotherapy comprises BEAM-ATG, i.e. BCNU, etoposide, cytarabine, melphalan before- and ATG (d+1 and +2: 3.75 mg/kg/d) after stem cell re-transfusion (d0).Results 26 MS patients (13 females, 13 males) with a mean age of 40.8±7.8 years, mean disease duration of 8.9±4.8 years and a mean expanded disease status scale (EDSS) score of 5.0±1.2 have been treated with aHSCT...Although a substantial proportion of patients reported improvements of neurological functions and less fatigue, follow-up is too short to comment on long-term outcomes.Conclusions The safety profile of aHSCT-in-MS is acceptable, but requires vigilant monitoring and optimized antibacterial and antiviral prophylactic care. Regarding the increased risk of CMV reactivation (4/7 CMV-seropositive patients) and herpes zoster (2/26), we decided to establish prophylaxis with the CMV inhibitor letermovir in CMV-seropositive patients and to vaccinate all patients with Shingrix® after transplantation.

    [VIRTUAL] Refractory and Resistant CMV Infections in Hematopoietic Cell Transplant Recipients in the Letermovir Primary Prophylaxis Era () -  Aug 14, 2020 - Abstract #IDWeek2020IDWEEK_1949;    
    Regarding the increased risk of CMV reactivation (4/7 CMV-seropositive patients) and herpes zoster (2/26), we decided to establish prophylaxis with the CMV inhibitor letermovir in CMV-seropositive patients and to vaccinate all patients with Shingrix® after transplantation. Our study showed a strong association between primary prophylaxis with letermovir and reduction in refractory or resistant CMV infections and CMV disease in allo-HCT recipients.

    These data support the reduction in clinical dosage of letermovir (to 240 mg) upon coadministration with cyclosporine. Trial completion date: Jul 2021 --> Jul 2022 | Trial primary completion date: Dec 2020 --> Dec 2021

    Journal:  Resistant or refractory cytomegalovirus infections after hematopoietic cell transplantation: diagnosis and management. (Pubmed Central) -  Aug 4, 2020   
    Many advances have been made to optimize future clinical trials for management of refractory or resistant CMV infections, and to better understand new resistance mechanisms to novel drugs. New drugs or strategies with limited toxicities are needed to improve outcomes of difficult to treat CMV infections in HCT recipients.

    Furthermore, we observed significant drug interactions between letermovir and tacrolimus. Cytomegalovirus (CMV) disease with resistance to ganciclovir (GCV) is difficult to manage in transplant patients.Letermovir may become a new option for treatment and prophylaxis of GCV-resistant CMV infection, but assessment of treatment response is difficult.Letermovir may lead to drug interactions via CYP3A4.

    Clinical, Review, Journal:  Letermovir and its role in the prevention of cytomegalovirus infection in seropositive patients receiving an allogeneic hematopoietic cell transplant. (Pubmed Central) -  Jul 9, 2020   
    Letermovir is a novel agent that was approved for primary prophylaxis in CMV-seropositive adult allogeneic hematopoietic cell transplant recipients. This review focuses on letermovir's novel mechanism; clinical trials supporting its United States Food and Drug Administration (FDA) approval and subsequent follow-up analyses; clinical considerations, with an emphasis on pharmacology; and lessons learned from solid organ transplant recipients, as well as potential future directions.

    [VIRTUAL] Disseminated Histoplasmosis in Lung Transplant Recipient Presenting as Hemophagocytic Lymphohistocytosis (ATS 2020 Virtual) -  Jul 6, 2020 - Abstract #ATSI2020ATS-I_5878;    
    Tacrolimus was changed to cyclosporine...This case highlights the importance of bone marrow biopsy in the work-up for pancytopenia and infection remains a serious concern in lung transplant patient presenting with fever of unknown origin. It also raises the question; should all lung transplant donor and/or recipient be screened for histoplasmosis?

    From a retrospective cohort of 1,283 seropositive adults who underwent HCT at Stanford University from January 2009 to May 2019, we analyzed 1,107 adults after the exclusion of patients on letermovir (N=78), who received a second HCT (N=78), or were not screened (N=8)...From 2015-2017 umbilical cord blood (UCB) recipients received valacyclovir 2000 mg thrice daily...Median overall antiviral exposure through D+100 was 30 days (range 0-100); ganciclovir (54%) was the most common initial agent used [median exposure 24 days (range 1-92)] vs 39% valganciclovir [median 25d (1-93d)] vs 7% foscarnet [median 10d (0-53d)]...
