Prevalence and Risk Factors of Post-Acute Sequela of COVID-19 in Adults with Systemic Autoimmune Rheumatic Diseases.

OBJECTIVE: Incidence and manifestations of post-acute sequelae of COVID-19 (PASC) are poorly defined among immunosuppressed populations. We reported, phenotyped, and assessed risk factors for PASC in adults with systemic autoimmune diseases. METHODS: Persons ≥18 years with systemic autoimmune diseases were recruited into a national, prospective cohort of SARS-CoV-2 vaccination between 12/2020-4/2021. Serial surveys assessed vaccination status, SARS-CoV-2 infection incidence, and disease flares. Participants reporting SARS-CoV-2 infection received a questionnaire assessing symptom duration, severity, and quality of life (QoL) impact; PASC was defined as ≥1 symptom persisting for >12 weeks. PASC syndromes were mapped via overlapping symptom domains. Characteristics were compared between participants who did versus did not report PASC. RESULTS: Among 1615 participants, 590 (36.5%) reported SARS-CoV-2 infection and were sent PASC surveys, 299 (50.7%) of whom responded >12 weeks following reported infection. Respondents were 1.62% female, 90.2% white, median (IQR) age 48(40-60) years with median (IQR) 3 (2-3) vaccine doses at time of first infection. Common diagnoses included inflammatory arthritis (38.5%) and inflammatory bowel disease (14.4%). 89/299 (29.8%) reported PASC, with the most reported symptom domain being neurological/psychological (83.1%); 84% reported an impact on QoL. Participants with PASC reported lower number of preceding vaccines (median [IQR] 2[2-3] versus 3[2-3]; p<0.001) and more reinfections (16.9% versus 5.7%; p=0.004). CONCLUSION: 29.8% of persons with systemic autoimmune disease in a large real-world cohort reported PASC, often affecting QoL. Preceding vaccination may reduce PASC, whereas multiple infections may increase risk, supporting ongoing booster vaccine campaigns and efforts to limit breakthrough infections.

A pragmatic tool to screen for pre-transplant cognitive impairment among potential candidates for liver transplant.

INTRODUCTION: Cognitive impairment (CI) among liver transplant (LT) candidates is associated with increased risk of waitlist mortality and inferior outcomes. While formal neurocognitive evaluation is the gold standard for CI diagnosis, the Montreal Cognitive Assessment (MoCA) is often used for first-line cognitive screening. However, MoCA requires specialized training and may be too lengthy for a busy evaluation appointment. An alternate approach may be the Quick Dementia Rating System (QDRS), which is patient- and informant-based and can be administered quickly. We compared potential LT candidates identified by MoCA and QDRS as potentially benefiting from further formal cognitive evaluation. METHODS: We identified 46 potential LT candidates enrolled at a single center of a prospective, observational cohort study who were administered MoCA and QDRS during transplant evaluation (12/2021-12/2022). Scores were dichotomized as (1) normal versus abnormal and (2) normal/mild impairment versus more-than-mild impairment. We calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of QDRS compared to MoCA. RESULTS: By MoCA, this population had a prevalence of 48% normal cognition, 48% mild, 4% moderate, and 0% severe impairment. This was categorized as 96% normal/mild and 4% more-than-mild impairment. When comparing to MoCA cognitive screening, QDRS had a sensitivity of 61%, specificity of 56%, NPV of 56%, and PPV of 61%. When identifying more-than-mild impairment, QDRS had a sensitivity of 100%, specificity of 73%, NPV of 100%, and PPV of 10%. CONCLUSION: The high sensitivity and NPV of QDRS in identifying more-than-mild impairment suggests it could identify potential LT candidates who would benefit from further formal cognitive evaluation. The ability to administer QDRS quickly and remotely makes it a pragmatic option for pre-transplant screening.

Patient reflections, challenges, and supports related to early liver transplant for severe alcohol-associated liver disease.

Transplant centers conventionally require at least 6 months of alcohol abstinence before offering liver transplants for alcohol-associated liver disease. However, early liver transplant (ELT)-proceeding with a transplant when clinically necessary without first meeting the conventional requirement-is increasingly gaining attention. In our study, we qualitatively assessed ELT recipients' perceived challenges and supports regarding alcohol-associated liver disease, transplant, and posttransplant survivorship. To diversify perspectives based on gender, race/ethnicity, age, time since ELT, and pretransplant abstinence duration, we purposively recruited ELT recipients and conducted semistructured interviews. Recruitment continued until data saturation. We analyzed transcripts using inductive thematic analysis. We interviewed 20 ELT recipients between June and December 2020 and identified themes within 3 participant-characterized time periods. Three themes emerged in life before severe illness: (1) alcohol as a "constant" part of life, (2) alcohol use negatively affecting relationships and work life, and (3) feeling "stuck" in the cycle of drinking. Two themes emerged during the severe illness period: (4) rapidity of health decline and (5) navigating medical care and the 6-month abstinence requirement. Finally, in life after transplant, 4 themes emerged: (6) feelings of shame or stigma and new self-worth, (7) reconnecting with others and redefining boundaries, (8) transplant as a defining point for sobriety, and (9) work-related challenges. Overall, participants expressed gratitude for receiving a gift of life and acknowledged their responsibilities to the new liver. ELT recipient experiences reveal complex psychosocial challenges related to addiction, inadequate support system, and stigma, particularly in the posttransplant period. The care of ELT recipients would be incomplete if focused solely on optimizing patient or graft survival.

Transplant Center Attitudes Toward Early Liver Transplant for Alcohol-associated Liver Disease.

Background: Many centers have removed 6-mo pretransplant alcohol abstinence requirements to provide early liver transplant (ELT) for individuals with severe alcohol-associated liver disease (ALD), but the practice remains controversial. Using data collected from a nationally distributed survey, this study examines the practices and attitudes of transplant centers in the United States regarding ELT. Methods: A 20-item survey designed to assess center practices and provider attitudes was distributed to 225 medical and surgical directors from 143 liver transplant centers via email. Results: Surveys were completed by 28.9% (n = 65) of directors and 39% (n = 56) of transplant centers. All responding centers reported evaluating patients for ELT. Circumstances for considering ELT included <6 mo of survival without a transplant (96.4%) and inability to participate in alcohol addiction therapy pretransplant (75%). Most (66%) directors indicated their center had established criteria for listing candidates with severe ALD for ELT. Regarding important factors for ELT candidate listing, 57.1% indicated patient survival, 37.5% indicated graft survival, and 55.4% indicated having a low risk of relapse. Only 12.7% of directors affirmed the statement, "Six months of pretransplant abstinence decreases the risk of relapse." Conclusions: More centers are providing ELT for severe ALD. Inability to participate in alcohol addiction therapy and <6 mo of survival are commonly reported circumstances for considering ELT. Continued investigation of posttransplant outcomes in patients receiving ELT is essential to establishing a national consensus for distributing this valuable resource.
