The influence of the cardiac cycle on the halo sign and its impact on the ultrasound diagnosis of giant cell arteritis.
No full textTo investigate whether hypoechoic wall thickness is influenced by the systole or diastole moment in the cardiac cycle and if this can influence US assessments of GCA. US videos of 100 consecutive patients (50 with GCA, 50 without) performed between January 2021 and June 2023 were reviewed. Intima-media thickness (IMT) of temporal (including common trunk, frontal and parietal branches), axillary and subclavian arteries were measured at two different time points, at systolic peak (SP) and at the end-diastole (ED). Differences between SP IMT and ED IMT, as well as in the halo count (HC) and in the OMERACT GCA Ultrasonography Score (OGUS) between these two times, were analysed. IMT was significantly higher (4.8-5%) at ED in all arteries, in both GCA and non-GCA groups. HC and OGUS were also higher in ED in both groups. In four non-GCA patients (8%), the HC was positive in ED and negative in SP; in all of them the HC in ED was 1. In the GCA group, the timing of the cardiac cycle did not influence the final US diagnosis; however, it did modify the HC in 14 patients (28%). IMT can fluctuate during the cardiac cycle, with higher measurements occurring at ED. This variability could potentially impact the accuracy of US diagnoses and assessments of GCA. If further research corroborates these findings, it may be imperative to revise the guidelines for employing US in diagnosing GCA in order to incorporate these nuanced aspects
Anthracyclines-induced cardiotoxicity in patients with early breast cancer carrying germline BRCA1/2 mutation: the BRCAN study.
No full text20.500.12530/87908BRCA1/2 genes play a critical role in genome stability and DNA repair. In animal models, loss of cardiomyocyte-specific BRCA1/2 is associated with DNA damage, apoptosis, cardiac dysfunction, and mortality following anthracycline exposure. However, whether these preclinical findings translate to humans remains unclear. Assess the impact of germline BRCA1/2 (gBRCA1/2) status on anthracyclines-induced cardiotoxicity (AIC) in patients with early breast cancer and no prior anti-HER2 therapy. This single-center retrospective/prospective cohort study focused on early breast cancer patients, treated with anthracycline-based chemotherapy in the neo/adjuvant setting, no prior anti-HER2 therapy, and known gBRCA1/2 status, normal baseline left ventricular ejection fraction (LVEF), and no previous cardiovascular disease. Follow-up assessments involved myocardial dysfunction blood biomarkers (MDBB), transthoracic echocardiography (TTE), and quality of life (QoL) questionnaires. The primary objective was LVEF changes comparing BRCA1/2 mutation carriers (gBRCA1/2m) vs non-carriers (gBRCA1/2wt). Secondary objectives included differences in MDBB and QoL. A total of 137 patients were included (103 gBRCA1/2wt and 34 gBRCA1/2m). Baseline characteristics were similar between groups. Compared to baseline, LVEF% reduction was -4.7[-12.0, 0.0] vs -9.5[-18.0, -5.0] in gBRCA1/2wt vs gBRCA1/2m, (P = .027). After adjusting for confounders, the difference in reduction in LVEF remained statistically significant at -4.5 [95%CI, -8.6, -0.4; P = .032]. No differences between MDBB (C-reactive protein, hsTnI, NT-proBNP, D-Dimer, ST-2, or Galectine-3) or QoL (MLHFQ and EQ5-D index) were detected. gBRCA1/2m patients could represent a higher-risk population for AIC. gBRCA1/2 status should be one of the factors to consider in deciding on adjuvant anthracycline necessity. This population could benefit from a cardio-oncology closer follow-up and cardioprotective strategies

The Natural History of Patients With Pre-Existing and De Novo Inflammatory Bowel Disease After Solid Organ Transplantation: EITOS Study of GETECCU.
No full text20.500.12530/87908Limited data are available on the outcome of inflammatory bowel disease (IBD) in patients with solid organ transplantation (SOT). We describe the natural history of pre-existing IBD and de novo IBD after SOT. This was a retrospective, multicenter study that included patients with pre-existing IBD at the time of SOT and patients with de novo IBD after SOT. The primary outcome was IBD progression, defined by escalation of medical treatment, surgical therapy, or hospitalization due to refractory IBD. Risk factors were identified using multivariate Cox proportional hazard analysis. A total of 177 patients (106 pre-existing IBD and 71 de novo IBD) were included. Most patients with pre-existing IBD (92.5%) were in remission before SOT. During follow-up, 32% of patients with pre-existing IBD had disease progression, with a median time between SOT and IBD progression of 2.2 (interquartile range, 1.3-4.6) years. In the de novo cohort, 55% of patients had disease progression with a median time to flare of 1.9 (interquartile range, 0.8-3.9) years after diagnosis. In the pre-existing IBD cohort, active IBD at the time of SOT (hazard ratio, 1.80; 95% confidence interval, 1.14-2.84; P = .012) and the presence of extraintestinal manifestations (hazard ratio, 3.10; 95% confidence interval, 1.47-6.54; P = .003) were predictive factors for IBD progression. One-third of patients with pre-existing IBD and about half of patients with de novo IBD have disease progression after SOT. Active IBD at the time of SOT and the presence of extraintestinal manifestations were identified as risk factors for IBD progression

Interobserver and Intraobserver Agreement on the Treatment of Infantile Hemangiomas.
No full textAlthough clinical practice guidelines exist for the treatment of infantile hemangiomas (IHs), recommendations are heterogeneous, and wide practice variations in IH management have been reported. To analyze the degree of agreement in treatment choices for IH among pediatric dermatologists in North America and Europe and assess whether there are differences across IH risk categories. This cross-sectional interrater and intrarater agreement study was conducted through a survey based on the Spanish Academy of Dermatology and Venereology IH prospective cohort. The survey used 50 vignettes of IH cases that were randomly selected from the cohort. It was administered twice in 2023, 1 month apart, to allow for interrater and intrarater agreement assessments. Data were analyzed in January 2024. The study involved pediatric dermatologists from North America (via the Pediatric Dermatology Research Alliance) and Europe (via the European Society of Pediatric Dermatologists). Participants were asked to choose 1 of 3 treatment options (propranolol, topical timolol, or observation) for each vignette. The primary outcome was the interrater agreement in treatment choices for IH cases, measured using κ statistics (Gwet AC1 coefficient). The global interobserver agreement among 90 pediatric dermatologists was fair (AC1, 0.38; 95% CI, 0.29-0.46). In North America (45 pediatricians), agreement was moderate (AC1, 0.41; 95% CI, 0.33-0.49), while in Europe (45 pediatricians) it was fair (AC1, 0.37; 95% CI, 0.28-0.46). The degree of agreement varied depending on the risk category of IH, with excellent agreement in high-risk IH and only moderate agreement in intermediate-risk and low-risk IHs. Propranolol was predominantly chosen for high-risk IH, while observation was most frequent for low-risk IH (55.9%). The second survey had 61 respondents, with no significant intrarater differences. The results of this survey study suggest that there is an important variability in the treatment of intermediate-risk and low-risk IH. The study findings support the need for more evidence regarding the role of topical timolol in IH treatment, which may help harmonize treatment approaches and improve consistency in IH management globally
Withdrawal of antitumour necrosis factor in inflammatory bowel disease patients in remission: a randomised placebo-controlled clinical trial of GETECCU.
No full text20.500.12530/87857Primary objectives: to compare the rates of sustained clinical remission at 12 months in patients treated with antitumour necrosis factor (anti-TNF) and immunomodulators who withdraw anti-TNF treatment versus those who maintain it. to evaluate the effect of anti-TNF withdrawal on relapse-free time, endoscopic and radiological activity, safety, quality of life and work productivity; and to identify predictive factors for relapse. Prospective, quadruple-blind, multicentre, randomised, controlled trial. Patients with ulcerative colitis or Crohn's disease in clinical remission for >6 months and absence of severe endoscopic (and radiological in Crohn's disease) lesions were randomised to maintain anti-TNF treatment (maintenance arm (MA)) or to withdraw it (withdrawal arm (WA)). All patients maintained immunomodulators. Patients were followed-up until month 12 or up to clinical relapse. One-hundred forty patients were randomised: 70 were allocated to the MA and 70 to the WA. The proportion of patients with sustained clinical remission at 12 months was similar in the MA and WA: 59/70 (84%), 95% CI=74% to 92% versus 53/70 (76%), 95% CI=64% to 85%. The proportion of patients with significant endoscopic lesions at the end of follow-up was 8.5% in the MA and 19% in the WA (p=0.1); a higher proportion of patients had faecal calprotectin >250 µg/g at the end of follow-up in the WA (p=0.01). The same percentage of patients in both groups had at least one adverse event (69%). The proportion of patients with serious adverse events was also similar in both groups (4% in MA vs 7% in WA). Anti-TNF withdrawal in selected patients with IBD in clinical, endoscopic and radiological remission has no impact on sustained clinical remission at 1 year although objective markers of activity were higher in patients who withdrew treatment. https://www.clinicaltrialsregister.eu/ctr-search/search?query=2015-001410-10 https://clinicaltrials.gov/study/NCT02994836
Thorough assessment of the effectiveness of belimumab in a large Spanish multicenter cohort of systemic lupus erythematosus patients.
No full text20.500.12530/87912To provide an overview on the current use of belimumab (BLM) in SLE patients in clinical practice and to examine its efficacy in terms of standardized outcomes, drug survival, as well as patient and safety profiles. A longitudinal retrospective multicenter cohort including SLE patients treated with BLM at 18 Spanish centers. Data was collected upon initiation of BLM, at 6 and 12 months after initiation, and at the last recorded visit. Changes in SLEDAI-2K, the proportion of patients who achieved LLDAS and DORIS 2021, and number of flares were compared between visits. Changes in damage, glucocorticoids use and employment status pre-BLM and post-BLM were also assessed. A total of 324 patients were included with a mean follow-up of 3.8 (±2.7) years. LLDAS was attained by 45.8%, 62% and 71% of patients, and DORIS by 24%, 36.2% and 52.5% on successive visits, respectively. A total of 27.2% of patients were in DORIS ≥50% of the visits and 46% in LLDAS-50. Flares and number of flares were significantly lower one year after treatment with BLM and no changes in damage accrual were observed. Mean (±SD) prednisone dose was significantly reduced over time, with 70 (24%) patients discontinuing GC. Our study not only demonstrates belimumab's efficacy in attaining treat-to-target goals in SLE patients, but also confirms its GC-sparing effect, and its prevention of flares and organ damage accrual
Visual manifestations in giant cell arteritis: identification of risk factors from the ARTESER Registry.
No full text20.500.12530/87855To determine the prevalence and predictive factors of visual manifestations in a large registry of patients with GCA. ARTESER is a large Spanish multicentre registry supported by the Spanish Society of Rheumatology. It includes patients with GCA from across the entire country diagnosed between June 2013 and March 2019. The variables collected at diagnosis were demographics, clinical manifestations (including all visual manifestations), laboratory, temporal artery biopsy, and imaging findings (ultrasound, FDG-PET/CT, MRI angiography, CT angiography). Patients with and without visual involvement were compared in a bivariate analysis. Multivariate logistic regression was performed to determine potential predictive factors of visual manifestations. The study population comprised 1636 GCA patients, of whom 599 (36.6%) presented visual manifestations. Anterior ischemic optic neuropathy was the most frequent (n = 274 of 599; 45.7%) ocular complication. The independent predictors that increased the risk (OR; 95% confidence interval) of visual involvement were older age (1.027; 1.009-1.045) and jaw claudication (1.724; 1.325-2.243). The variables associated with a reduced risk were polymyalgia rheumatica (0.541; 0.414-0.708), fever (0.373; 0.264-0.527), longer symptom duration (0.946; 0.909-0.985) and higher erythrocyte sedimentation rate (ESR) (0.992; 0.988-0.997), common features of patients with large vessel GCA. One-third of GCA patients present visual manifestations at diagnosis. Older age and jaw claudication are independent predictors of visual manifestations, whereas polymyalgia rheumatica, fever, longer symptom duration and high ESR reduce the risk of visual involvement
Safety and quality of life with maintenance olaparib plus bevacizumab in older patients with ovarian cancer: subgroup analysis of PAOLA‑1/ENGOT-ov25.
No full text20.500.12530/87854In PAOLA-1/ENGOT-ov25, the addition of olaparib to bevacizumab maintenance improved overall survival in patients with newly diagnosed advanced ovarian cancer. We describe the safety profile and quality of life (QoL) of this combination in older patients in PAOLA-1. Safety (CTCAE v4.03) and QoL (EORTC QoL Questionnaires Core 30 and Ovarian 28) data were collected. We compared safety by age (≥70 vs Of 806 patients randomized, 142 were ≥70 years old (olaparib-containing arm: n = 104; placebo arm: n = 38). Older patients treated with olaparib exhibited a similar safety profile to younger patients, except for higher rates of all grades of lymphopenia and grade ≥3 hypertension (31.7% vs 21.6%, P =.032 and 26.9% vs 16.7%, P =.019, respectively). No hematological malignancy was reported. Two years after randomization, mean Global Health Status and cognitive functioning seemed better with olaparib than bevacizumab alone (adjusted mean difference: +4.47 points [95% CI, -0.49 to 9.42] and +4.82 [-0.57 to 10.21], respectively), and other QoL items were similar between arms. In the olaparib-containing arm, older patients with baseline GVS ≥ 1 (n = 48) exhibited increased toxicity and poorer QoL than those with GVS of 0 (n = 34). Among older patients in PAOLA-1, olaparib plus bevacizumab had a manageable safety profile and no adverse impact on QoL. Additional data are required to confirm these results in more vulnerable patients.(ClinicalTrials.gov Identifier: NCT02477644)
