Abstract Background The 2023 Duke–International Society of Cardiovascular Infectious Diseases (ISCVID) criteria for infective endocarditis (IE) were introduced to improve classification of IE for research and clinical purposes. External validation studies are required. Methods We studied consecutive patients with suspected IE referred to the IE team of Amsterdam University Medical Center (from October 2016 to March 2021). An international expert panel independently reviewed case summaries and assigned a final diagnosis of “IE” or “not IE,” which served as the reference standard, to which the “definite” Duke-ISCVID classifications were compared. We also evaluated accuracy when excluding cardiac surgical and pathologic data (“clinical” criteria). Finally, we compared the 2023 Duke-ISCVID with the 2000 modified Duke criteria and the 2015 and 2023 European Society of Cardiology (ESC) criteria. Results A total of 595 consecutive patients with suspected IE were included: 399 (67%) were adjudicated as having IE; 111 (19%) had prosthetic valve IE, and 48 (8%) had a cardiac implantable electronic device IE. The 2023 Duke-ISCVID criteria were more sensitive than either the modified Duke or 2015 ESC criteria (84.2% vs 74.9% and 80%, respectively; P < .001) without significant loss of specificity. The 2023 Duke-ISCVID criteria were similarly sensitive but more specific than the 2023 ESC criteria (94% vs 82%; P < .001). The same pattern was seen for the clinical criteria (excluding surgical/pathologic results). New modifications in the 2023 Duke-ISCVID criteria related to “major microbiological” and “imaging” criteria had the most impact. Conclusions The 2023 Duke-ISCVID criteria represent a significant advance in the diagnostic classification of patients with suspected IE.

Objective To evaluate the incidence and outcomes of large artery (LA) involvement among patients with giant cell arteritis (GCA) and to compare LA involvement to non-GCA patients. Methods The study included Olmsted County, Minnesota, USA residents with incident GCA between 1950 and 2016 with follow-up through 31 December 2020, death or migration. A population-based age-matched/sex-matched comparator cohort without GCA was assembled. LA involvement included aortic aneurysm, dissection, stenosis in the aorta or its main branches diagnosed within 1 year prior to GCA or anytime afterwards. Cumulative incidence of LA involvement was estimated; Cox models were used. Results The GCA cohort included 289 patients (77% females, 81% temporal artery biopsy positive), 106 with LA involvement. Reported cumulative incidences of LA involvement in GCA at 15 years were 14.8%, 30.2% and 49.2% for 1950–1974, 1975–1999 and 2000–2016, respectively (HR 3.48, 95% CI 1.67 to 7.27 for 2000–2016 vs 1950–1974). GCA patients had higher risk for LA involvement compared with non-GCA (HR 3.22, 95% CI 1.83 to 5.68 adjusted for age, sex, comorbidities). Thoracic aortic aneurysms were increased in GCA versus non GCA (HR 13.46, 95% CI 1.78 to 101.98) but not abdominal (HR 1.08, 95% CI 0.33 to 3.55). All-cause mortality in GCA patients improved over time (HR 0.62, 95% CI 0.41 to 0.93 in 2000–2016 vs 1950–1974) but remained significantly elevated in those with LA involvement (HR 1.89, 95% CI 1.39 to 2.56). Conclusions LA involvement in GCA has increased over time. Patients with GCA have higher incidences of LA involvement compared with non-GCA including thoracic but not abdominal aneurysms. Mortality is increased in patients with GCA and LA involvement highlighting the need for continued surveillance.

ABSTRACT Nintedanib is a medication that has been increasingly used for treatment of idiopathic and progressive pulmonary fibrosis. In this case series, we describe 3 patients with colitis symptoms associated with nintedanib use. Nintedanib discontinuation resulted in symptomatic resolution in all patients. Budesonide decreased symptoms in 1 patient. Clinicians should be vigilant in taking a thorough medication history and include nintedanib as a cause for gastrointestinal symptoms including colitis.

AbstractINTRODUCTIONPatients with dementia with Lewy bodies (DLB) may have Alzheimers disease (AD) pathology that can be detected by plasma biomarkers. Our objective was to evaluate plasma biomarkers of AD and their association with positron emission tomography (PET) biomarkers of amyloid and tau deposition in the continuum of DLB, starting from prodromal stages of the disease.METHODSThe cohort included patients with isolated rapid eye movement (REM) sleep behavior disorder (iRBD), mild cognitive impairment with Lewy bodies (MCI‐LB), or DLB, with a concurrent blood draw and PET scans.RESULTSAbnormal levels of plasma glial fibrillary acidic protein (GFAP) were found at the prodromal stage of MCI‐LB in association with increased amyloid PET. Abnormal levels of plasma phosphorylated tau (p‐tau)‐181 and neurofilament light (NfL) were found at the DLB stage. Plasma p‐tau‐181 showed the highest accuracy in detecting abnormal amyloid and tau PET in patients with DLB.DISCUSSIONThe range of AD co‐pathology can be detected with plasma biomarkers in the DLB continuum, particularly with plasma p‐tau‐181 and GFAP.

AbstractBackgroundDespite studies of dermatologic manifestations in adults with inflammatory bowel disease (IBD), little is known about the prevalence of IBD‐associated skin lesions and their correlation with IBD severity in children. We aimed to address these knowledge gaps in our single‐center cohort of children with IBD.MethodsRetrospective chart review of 528 children and adolescents (≤18 years old) with IBD and seen at Mayo Clinic (Rochester, MN) between 1999 and 2017 was conducted. The Chi‐Square/Fischer's exact test (with p ≤ .05 to signify statistical significance) was applied to compare categorical outcomes between Crohn's disease (CD) and ulcerative colitis (UC) patients.ResultsIn total, 425 IBD patients (64.9% CD, 53% males) and ≥1 dermatologic diagnosis were included. Presence of ≥1 cutaneous infection was recorded in 42.8% of participants. Acne was the most common non‐infectious dermatologic condition (30.8%), followed by eczema (15.8%) and perianal skin tags (14.6%). Angular cheilitis (p = .024), keratosis pilaris (KP, p = .003), and perianal skin complications (i.e., skin tags, fistula, and abscesses; all p < .001) were more frequently diagnosed among children with CD, while fungal skin infections (p = .017) were more frequently diagnosed in UC patients. Severity of IBD correlated with higher prevalence of perianal fistula (p = .003), perianal abscess (p = .041), psoriasis (p < .001), and pyoderma gangrenosum (PG, p = .003).ConclusionsBoth IBD‐specific and IBD‐nonspecific dermatologic conditions are very prevalent in childhood IBD, the most common being infectious. Children with CD are more likely to experience angular cheilitis, KP, and perianal skin findings than those with UC. Perianal disease, psoriasis, and PG are associated with more severe IBD.
