- Objective: Benzodiazepines and related drugs (BDZRs) have been associated with an increased risk of Alzheimer's disease (AD) in later life. Despite this, it remains unclear whether ongoing BDZR use may further accelerate cognitive decline in those diagnosed with mild to moderate AD. Design: This study was embedded within NILVAD, a randomized controlled trial of nilvadipine in mild to moderate AD. Cognition was measured at baseline and 18 months using the Alzheimer Disease Assessment Scale, Cognitive Subsection (ADAS-Cog). We assessed predictors of long-term BDZR use and analyzed the effect of ongoing BDZR use on ADAS-Cog scores at 18 months. Additionally, the impact of BDZR use on adverse events, incident delirium, and falls over 18-month follow-up was assessed adjusting for relevant covariates. Setting and Participants: 448 participants with mild to moderate AD recruited from 23 academic centers in 9 European countries. Results: Overall, 14% (62/448) were prescribed an ongoing BDZR for the study duration. Increasing total number of (non-BDZR) medications was associated with a greater likelihood of BDZR prescription (odds ratio 1.16, 95% confidence interval 1.05-1.29). At 18 months, BDZR use was not associated with greater cognitive decline on the ADAS-Cog controlling for baseline ADAS-Cog scores, age, gender, study arm, and other clinical covariates (beta = 1.62, -1.34 to 4.56). However, ongoing BDZR use was associated with a greater likelihood of adverse events [incidence rate ratio (IRR) 1.19, 1.05-1.34], incident delirium (IRR 2.31, 1.45-3.68), and falls (IRR 1.66, 1.02-2.65) over 18 months that persisted after robust adjustment for covariates. Conclusions and Implications: This study found no effect of ongoing BDZR use on ADAS-Cog scores in those with mild to moderate AD over 18 months. However, ongoing use of these medications was associated with an increased risk of adverse events, delirium, and falls. Thus, BDZR use should be avoided where possible and deprescribing interventions should be encouraged in older adults with AD. (C) 2019 AMDA - The Society for Post-Acute and Long-Term Care Medicine.

- Recent RNA virus outbreaks such as Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Ebola virus (EBOV) have caused worldwide health emergencies highlighting the urgent need for new antiviral strategies. Targeting host cell pathways supporting viral replication is an attractive approach for development of antiviral compounds, especially with new, unexplored viruses where knowledge of virus biology is limited. Here, we present a strategy to identify host-targeted small molecule inhibitors using an image-based phenotypic antiviral screening assay followed by extensive target identification efforts revealing altered cellular pathways upon antiviral compound treatment. The newly discovered antiviral compounds showed broad-range antiviral activity against pathogenic RNA viruses such as SARS-CoV-2, EBOV and Crimean-Congo hemorrhagic fever virus (CCHFV). Target identification of the antiviral compounds by thermal protein profiling revealed major effects on proteostasis pathways and disturbance in interactions between cellular HSP70 complex and viral proteins, illustrating the supportive role of HSP70 on many RNA viruses across virus families. Collectively, this strategy identifies new small molecule inhibitors with broad antiviral activity against pathogenic RNA viruses, but also uncovers novel virus biology urgently needed for design of new antiviral therapies.

Tidskriftsartikel (refereegranskat)abstract
- Background: Co-exposure to environmental contaminants present in fish could mitigate the beneficial effects of fish consumption and possibly explain the lack of association observed for mortality in some geographical regions.Objective: To assess the independent associations of dietary exposure to polychlorinated biphenyls (PCBs) and long-chain omega-3 fish fatty acids intake with cardiovascular and cancer mortality.Methods: We used the prospective population-based Swedish Mammography Cohort and the Cohort of Swedish Men comprising 32 952 women and 36 545 men, free from cancer, cardiovascular disease and diabetes at baseline in 1998. Validated estimates of dietary PCBs and long-chain omega-3 fish fatty acids [i.e. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] intake were obtained via a food frequency questionnaire at baseline. Information on death was ascertained through register linkage.Results: During a mean follow-up of 15.5 years, we ascertained 16 776 deaths. We observed for cardiovascular mortality, comparing extreme quintiles in multivariable models mutually adjusted for PCBs and EPA-DHA, dose-dependent associations for dietary PCB exposure, hazard ratio (HR) 1.31 (CI 95%: 1.08 to 1.57; P-trend 0.005) and for dietary EPA-DHA intake, HR 0.79 (CI 95%: 0.66 to 0.95; P-trend 0.041). For cancer mortality, no clear associations were discerned.Conclusion: The beneficial effect of fish consumption on the cardiovascular system seems compromised by co-exposure to PCBs - one likely explanation for the inconsistent associations observed between fish consumption and mortality.

- Background: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS). DMF is included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the effectiveness and safety of DMF with focus on patients treated at least 36 months in the IMSE study.Methods: Descriptive data of Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS) and Adverse Events (AEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 2349 DMF-treated patients were included between March 2014 and June 2020 with an overall drug survival rate of 45%. The main reasons for discontinuation were AEs (50%) and lack of effect (30%). 186 AEs were reported to the Swedish Medical Products Agency, of which 59 were serious. A total of 8 patients have died during DMF treatment or within 6 months of treatment discontinuation. 36 month cohort: 940 patients had con-tinuous treatment for at least 36 months. This cohort had a mean age of 42 years and a mean treatment duration of 56 months. The majority (50%) had switched from interferon or glatiramer ace-tate, and (24%) were treatment naïve (TN). Significant improve-ments in mean values at 36 months of treatment compared to baseline for the 36-month cohort were noted for MSSS, SDMT, MSIS-29 Psychological, EQ-5D and VAS. When TN patients were solely assessed (n=230) improvements were noted for all above mentioned measures as well as MSIS-29 Psychological. The remaining patients in the cohort; treatment experienced patients (n=710) displayed significant improvements only for MSSS, MSIS-29 Psychological and EQ-5D. TN patients had a mean duration from diagnosis to treatment start of 5 months com-pared to 91 months for the remaining cohort. TN were also younger than the remaining cohort (37 years vs 43 years).Conclusions: DMF demonstrates clinical improvements in patients treated 36 months, more pronounced in TN patients. However; due to the high discontinuation rate there is an unavoidable selection bias. Continued follow up is needed to assess the effectiveness and safety of DMF over longer time periods in a real world setting.

- Background: Natalizumab (NTZ) is a highly effective disease modulatory treatment for relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important for evalua-tion of long-term safety and effectiveness in a real-world setting. To this end, the “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 1) was initiated upon NTZ launch in Sweden (August 2006).Objectives: To follow-up the long-term effectiveness and safety of NTZ in a real-world setting, with focus on patients treated at least 10 years.Methods: IMSE 1 includes patients starting NTZ treatment and data is collected from the nationwide Swedish Neuro Registry (NeuroReg). Adverse events (AEs), JC-virus status (JCV) and clinical effectiveness measures are registered in NeuroReg pro-spectively. Effectiveness measures were assessed using the Wilcoxon Signed Rank Test.Results: A total of 3291 patients were included in the IMSE 1 study from August 2006 until June 2020 (72% female; mean age 36 years; 80% RRMS; mean treatment duration 50 months). 171/3291 patients (5%) had been treated for at least 120 months (73% female; men age 36 years; 87% RRMS; mean treatment duration 139 months). A total of 64% (110/171) were treated with interferons or glatiramer acetate prior to NTZ treatment. Over the duration of follow-up discontinued 21% (35/171) their NTZ treat-ment of which 46% (16/35) discontinued due to JCV positive (JCV+). In total, 27% (46/171) of these patients were JCV+ with a mean JCV index of 1.2±1.0 (4% missing data). The mean num-ber of relapses were reduced from 0.84 one year before NTZ treat-ment start to 0.00 during the first treatment year (12% missing data). All clinical effectiveness measures (Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Multiple Sclerosis Impact Scale (MSIS-29) and Symbol Digit Modalities Test (SDMT)) showed improvement in mean between baseline and 120 months. However, only MSSS, MSIS-29 psy-chological and SDMT were statistically significant. Over the entire observation time, 114 Serious AEs had been reported to the Swedish Medical Product Agency and included nine cases (2 fatal) of progressive multifocal leukoencephalopathy (PML) of which eight between year 2008 and 2012, and one in 2018. 17 patients died during or within 6 months of last NTZ infusion. None were judged to be directly associated with NTZ.Conclusions: NTZ is generally well tolerated with sustained effectiveness regarding cognitive, physical and psychological measures, as well as relapse-control.

- Background: Subcutaneous peginterferon beta-1a (PegIFN) was approved for relapsing-remitting multiple sclerosis (RRMS) in Europe 2014. The clinical trial program showed that PegIFN reduced the relapse rate and proportion with disability progression compared to placebo. At its launch in Sweden, PegIFN was included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 6), providing possibilities to track long-term effectiveness and safety in a population-based setting.Objectives: To follow-up the long-term effectiveness and safety of PegIFN treatment in Swedish patients in a real-world context.Methods: Data was obtained from the nationwide Swedish Neuro Registry (NeuroReg) between June 2015 and May 2020. Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: A total of 364 patients (78% female; 87% RRMS; mean age at treatments start 43 years) were followed up to 57 months (mean 20 months), of which 200 (55%) patients had been treated for at least 12 months. The majority of the patients had switched from other injectables (164 patients, 45%) or were treatment naïve (90 patients, 25%) prior to treatment with PegIFN. Over the dura-tion of the follow-up, 68% (247/364) patients discontinued their PegIFN treatment for various reasons (60% adverse events, 24% lack of effect) and switched mainly to rituximab (105 patients, 43%). The overall drug survival was 32%, 40% for men and 30% for women. The one- and two-year drug survival rate was 57% and 40%, respectively. The mean number of relapses were reduced from 0.35 one year before treatment start to 0.11 one year after (35% missing data). All clinical effectiveness measures (Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life – 5-Dimension test (EQ-5D), Visual Analogue Score (VAS) and Symbol Digit Modalities Test (SDMT)) remained stable. Statistically significant changes were observed in SDMT (p=0.027). A total number of 18 adverse events (6 serious) were reported to Swedish Medical Product Agency.Conclusions: These findings are consistent with PegIFN being a safe disease modifying treatment, however, a relatively high pro-portion of patients switched due to adverse events. All clinical effectiveness measures remained stable in patients treated with PegIFN for at least 12 months in this nationwide population-based real-world study. Longer follow up is needed to address the long-term effectiveness.
