Importance There is a lack of long-term efficacy and safety data on hereditary transthyretin amyloidosis with polyneuropathy (hATTR-PN) and on RNA interference (RNAi) therapeutics in general. This study presents the longest-term data to date on patisiran for hATTR-PN. Objective To present the long-term efficacy and safety of patisiran in adults with hATTR-PN. Design, Setting, and Participants This global open-label extension (OLE) of the APOLLO randomized clinical trial and phase 2 OLE study enrolled patients from 43 hospitals or clinical centers across 19 countries between July 2015 and August 2017, with follow-up until November 2022. Of 212 eligible patients with hATTR who completed the phase 3 APOLLO or phase 2 OLE parent studies, 211 enrolled in and 138 completed the global OLE. Intervention Patisiran, 0.3 mg/kg, intravenously once every 3 weeks for up to 5 years. Main Outcomes and Measures Outcomes evaluated at year 5 of the global OLE included disability (polyneuropathy disability [PND] score); polyneuropathy severity (Neuropathy Impairment Score [NIS]), nutritional status (modified body mass index [mBMI]), quality of life (Norfolk Quality of Life–Diabetic Neuropathy [Norfolk QOL-DN]), and Rasch-Built Overall Disability Scale (R-ODS), with no statistical hierarchy. Safety, survival probability, and mortality were also assessed. Results At the global OLE baseline, the mean (SD) age was 61.3 (12.3) years, and 156 patients (73.9%) were male. In 138 patients completing the study, PND scores remained stable or improved in 89 patients (65.0%), NISs showed a mean (SD) change of 10.9 (14.7), and mean (SD) mBMI (calculated as weight in kilograms divided by height in meters squared times serum albumin in grams per liter) increased by 46.4 (120.7) over 5 years from baseline. Norfolk QOL-DN and R-ODS scores showed mean (SD) changes of 4.1 (16.7) and –3.7 (6.2), respectively. Adverse events (AEs) leading to study withdrawal occurred in 47 patients (22.3%). Infusion-related reactions were the most common treatment-related AE (n = 34 [16.1%]). Overall, 41 patients (19.4%) died during the study. Patisiran treatment in the parent study and low familial amyloid polyneuropathy score at parent study baseline were associated with significantly improved survival. Conclusions and Relevance In the longest study of an RNAi therapeutic for any disease, patisiran treatment resulted in modest changes for patients with hATTR-PN with an acceptable safety profile. These results highlight the importance of initiating early treatment for hATTR and the potential of RNAi therapeutics in medicine. Trial Registration ClinicalTrials.gov Identifier: NCT02510261

Abstract BACKGROUND We sought to characterize the cognitive profile among individuals with mild cognitive impairment with Lewy bodies (MCI‐LB) to help guide future clinical criteria. METHODS Systematic review and meta‐analysis included MCI‐LB studies with cognitive data from PubMed, Embase, Web of Science, and PsycINFO (January 1990 to March 2023). MCI‐LB scores were compared to controls, MCI due to Alzheimer's disease (MCI‐AD), and dementia with Lewy bodies (DLB) groups with random‐effects models. RESULTS We included 26 studies and 2823 participants. Across all domains, the MCI‐LB group performed worse than controls and better than DLB. Compared to MCI‐AD, the MCI‐LB group performed worse in attention/processing speed ( g = –0.24, 95% confidence interval [CI]: –0.35, –0.12), attention/executive ( g = –0.42, 95% CI: –0.56, –0.28); better in verbal immediate recall ( g = 0.37; 95% CI: 0.15, 0.59) and delayed memory ( g = 0.40; 95% CI: 0.22, 0.58). DISCUSSION The cognitive profiles in MCI‐LB and MCI‐AD are consistent with established profiles in DLB and AD. Neuropsychological assessment may be helpful in differential diagnosis, even in early disease states. Highlights We performed a systematic review and meta‐analysis for cognition in mild cognitive impairment with Lewy bodies (MCI‐LB). Compared to MCI due to Alzheimer's disease (MCI‐AD), MCI‐LB had worse attention, executive function, and processing speed. Compared to MCI‐AD, MCI‐LB had better verbal immediate and delayed recall. The MCI‐LB group was worse on all cognitive domains than controls, and better than dementia with Lewy bodies. Studies used different tests and there is a need for global efforts for harmonization.

INTRODUCTION: Spondyloarthritis (SpA), the most common extraintestinal manifestation of inflammatory bowel disease (IBD), is reported in up to 39% of patients with IBD. Despite this high prevalence, risk factors of developing SpA in patients with IBD are not well described. In this study, we aimed to determine the factors associated with SpA symptoms and their prevalence in an IBD cohort. METHODS: Two validated screening questionnaires for the detection of SpA in IBD (DETAIL = DETection of Arthritis in Inflammatory boweL diseases, IBIS-Q = IBD Identification of Spondyloarthritis Questionnaire) were administered to patients with IBD without a prior diagnosis of SpA in 6 US academic medical centers. Demographic data, IBD characteristics, and medication history were recorded. RESULTS: Screening questionnaires were completed by 588 patients (220 ulcerative colitis, 349 Crohn's disease, and 19 IBD-unclassified), with a median age of 40 years (interquartile range 30–53) and median disease duration of 12 years (interquartile range 6–22). The number of positive screens was 130 (22%) for DETAIL, 196 (33%) for IBIS-Q, and 204 (35%) for either DETAIL or IBIS-Q. Age, female sex, history of smoking, prior bowel surgery, and history of any biologic or targeted small molecule exposure were associated with a positive screen on univariate analysis. After multivariate analysis, female sex (odds ratio [OR] 2.03, 95% confidence interval [CI] 1.41–2.93), older age (OR 1.02, 95% CI 1.01–1.04), history of smoking (OR 1.67, 95% CI 1.04–2.69), and history of any biologic or targeted small molecule exposure (OR 2.27, 95% CI 1.34–3.84) were independently associated with positive screens. Higher number of biologic exposures was associated with higher risk of positive screens, with the highest risk seen with 3 or more exposures (OR 3.25, 95% CI 1.75–6.03). DISCUSSION: A substantial number of patients with IBD screen positive for SpA symptoms, indicating a potentially high burden of undiagnosed illness. Factors associated with SpA symptoms include older age, female sex, and more severe disease (based on increased number of advanced therapies or prior surgery), whereas IBD phenotype does not independently increase the risk of a positive SpA screen. Further studies are needed to confirm these findings and better characterize SpA in IBD.

ObjectiveSpondyloarthritis (SpA) is the most common extraintestinal manifestation of inflammatory bowel disease (IBD). The application of screening tools to detect SpA in patients with IBD may lead to earlier recognition of SpA and affect treatment decisions.MethodsA combination of two previously described SpA screening questionnaires, the Detection of Arthritis in Inflammatory Bowel Disease (DETAIL) and IBD Identification of Spondyloarthritis Questionnaire (IBIS‐Q), was administered to consecutive patients with IBD attending IBD specialty clinics in six US academic medical centers. Demographic data, IBD, and rheumatology history were extracted by chart review.ResultsA total of 669 patients were analyzed. The median age was 40 years (interquartile range [IQR] 30–54) with a median disease duration of 12 years (IQR 6–22) and moderate to severe IBD based on medication exposure and history of bowel surgery. A total of 81 patients (12%) carried a diagnosis of an inflammatory rheumatic disease, whereas 75 (11%) had consulted a rheumatologist during the previous year. Using published cutoffs, 180 out of 669 patients (27%) screened positive with DETAIL, 266 (40%) with IBIS‐Q, and 275 (41%) with either questionnaire. Axial symptoms were more frequently reported than peripheral musculoskeletal complaints. Notably, 189 out of 275 (69%) screen‐positive patients had neither a documented inflammatory rheumatic disease diagnosis nor a visit with a rheumatologist within the past year.ConclusionA substantial proportion of patients with IBD have symptoms suggestive of SpA, and many of these may have undiagnosed SpA. The IBIS‐Q questionnaire appears to identify more potential SpA cases than DETAIL. Strategies are needed to prioritize rheumatology consultations for those patients with IBD who are most likely to benefit.

Background: Diagnostic uncertainty caused by the low positive predictive value of HEV-specific IgM antibody (Ab) testing in a low-prevalence setting. We investigated the utility of a two-step HEV IgM Ab testing approach for diagnosing HEV infection. Methods: We retrospectively reviewed all adults who underwent HEV IgM Ab and/or HEV RNA testing from July 2013 through June 2023 at Mayo Clinic. Two-step HEV IgM testing involved initial testing using recomWell HEV IgM ELISA (Mikrogen, Neuried, Germany), with reflex to recomLine HEV IgM Strip (Mikrogen, Neuried, Germany) on all recomWell HEV IgM-reactive or IgM-equivocal specimens, as recomLine HEV IgM has higher specificity than recomWell HEV IgM but is more labor-intensive. Results: A total of 1640 patients had HEV IgM Ab or HEV RNA testing, including 1293 (79%) with only HEV IgM Ab testing, 213 (13%) with only HEV RNA testing, and 134 (8%) with both HEV IgM Ab and HEV RNA testing. Eighteen HEV infections were diagnosed with acute (N=16) and chronic (N=2) infections. Two-step IgM Ab testing did not identify 2 solid organ transplant recipients with chronic HEV infection. In acute HEV infection with HEV viremia, 3 out of 4 patients (2 solid organ transplant recipients and 1 patient with Guillain-Barre syndrome) were treated with ribavirin. Conclusions: A two-step HEV IgM Ab test may accurately diagnose acute HEV infection in immunocompetent persons. However, this approach fails to identify chronic HEV infection in immunocompromised individuals who need HEV RNA testing to establish the diagnosis.

Adolescents and young adults living with advanced cancer must often discover new rules for living during cancer treatment. Such experiences may lead them to emerge to higher levels of consciousness and find personal meaning in these experiences. Newman’s theory of health as expanding consciousness was this qualitative research study’s framework examining hope’s role for adolescents and young adults living with advanced cancer. Fifteen participants aged 12-21 years created written narratives and illustrations to describe their experiences with hope. We propose an updated theoretical model in which hope facilitates expanding consciousness in adolescents and young adults living with advanced cancer.
