The hidden link between late-onset seizures and cerebral amyloid angiopathy: A case-control study.

OBJECTIVE: Epileptic seizures occurring in late adulthood often remain of unknown origin. Sporadic cerebral amyloid angiopathy (CAA) is a cerebral small vessel disease characterized by intracerebral hemorrhage, microhemorrhage and superficial siderosis, occurring mostly in elderly. This observational case-control study aimed to assess the occurrence of CAA in patients experiencing their first seizure in late adulthood. METHODS: We enrolled consecutive patients aged ≥55 years presenting with late-onset seizures (LOS) to the emergency departments or outpatient clinics of two Italian centers, from April 2021 to October 2022. Two age-matched control subjects with neurological symptoms other than epileptic seizure were recruited for each enrolled case. All participants underwent brain MRI (1.5 Tesla) including blood-sensitive sequences and were assessed for probable CAA diagnosis according to Boston criteria 2.0. Chi-squared test was performed to evaluate group differences. Univariate logistic regression analysis tested the association between clinical variables and CAA. RESULTS: We included 65 patients with LOS (27 females; mean age 72.2 ± 8.9 years) and 130 controls (49 females; mean age 70.3 ± 8.9 years). Diagnosis of probable CAA was achieved in 10.8% (7/65) of LOS patients and 2.3% (3/130) controls, with a statistically significant difference (p = 0.011). The OR for CAA in the LOS group was 5.2 as compared to the control group (95% CI = 1.3-20.6, p = 0.02). SIGNIFICANCE: The frequency of CAA is significatively higher in patients with LOS as compared to other neurological diseases, suggesting that a portion of LOS of unknown or vascular origin are associated with CAA. PLAIN LANGUAGE SUMMARY: Late-onset seizures (LOS) are very frequent in the elderly and often have no clear cause. Cerebral amyloid angiopathy (CAA) is a condition where amyloid proteins build up in the blood vessels of the brain, causing them to become weak and prone to bleeding. In this study, we explored the occurrence of CAA in people with LOS. We found that people with LOS were more likely to have a diagnosis of CAA than controls (i.e., people with other neurological diseases).

Functional seizures and binge eating disorder: A cross-sectional study.

OBJECTIVE: Functional seizures (FS) are brief, involuntary changes in behaviour or consciousness, distinct from epileptic seizures, potentially associated with psychological dissociation. Binge eating disorder (BED) was linked to psychological and somatic dissociation also. However, any connection between FS and BED is insufficiently explored. We aimed to assess BED prevalence in individuals with FS, anxiety/depression (AD), and healthy subjects (HS), to investigate dissociation's link to binge eating, and to explore psychological characteristics of FS individuals. METHOD: Participants underwent evaluations based on ILAE guidelines and DSM-5 criteria, including questionnaires assessing binge eating, dissociation, anxiety, depression and personality traits. Inclusion criteria were age > 18 years, no history of substance abuse, no history of epilepsy, and no use of medications inducing eating disorders. RESULTS: We found significantly more frequent and severe binge-eating symptoms in individuals with FS and AD compared to HS. Depression and dissociation correlated with binge-eating symptoms in both AD and FS groups. The PID-5 facet 'Perseveration' predicted binge-eating attitudes only in FS individuals; they reported more childhood emotional neglect and increased disinhibition compared do AD people. DISCUSSION: This study underscores the commonality of binge-eating symptoms in FS individuals, emphasizing its association with dissociation symptoms. This finding support the hypothesis of a link between dissociation and eating disorders. Unique clinical characteristics in individuals with FS were identified, as a compulsive dimension related to binge-eating symptoms, providing a comprehensive understanding of their psychological profile and guiding targeted therapeutic interventions.

Perampanel in post-stroke epilepsy: Clinical practice data from the PERampanel as Only Concomitant antiseizure medication (PEROC) study.

INTRODUCTION: Post-stroke epilepsy (PSE) is one of the most common causes of acquired epilepsy. Nevertheless, there is limited evidence regarding the clinical profile of antiseizure medications (ASMs) in PSE. This study aims to evaluate the 12-month effectiveness and tolerability of perampanel (PER) used as only add-on treatment in patients with PSE in a real-world setting. METHODS: We performed a subgroup analysis of PSE patients included in a previous retrospective, longitudinal, multicentre observational study on adults. Treatment discontinuation, seizure frequency and adverse events were collected at 3, 6 and 12 months. Sub-analyses by early (≤1 previous ASM) or late PER add-on were also conducted. RESULTS: Our analysis included 56 individuals with PSE, characterized by varying initial treatment modalities and timeframes relative to disease onset. We found notable retention rates (92.8%, 83.7%, and 69% at 3, 6, and 12 months), with treatment withdrawal mainly due to poor tolerability. One year after PER introduction, seizure frequency significantly reduced, with a responder rate (≥50% reduction) of 83.9% and a seizure-free rate of 51.6%. Adverse events occurred in 25 (46.3%) patients, mainly dizziness, irritability, and behavioural disorders. No major statistical differences were found between early (30 patients, 53.6%) and late add-on groups, except for a higher 6-month responder rate in the early add-on group. CONCLUSION: Adjunctive PER was effective and well-tolerated in patients with PSE in a real-world setting. Perampanel demonstrated good efficacy and safety as both early and late add-on treatment, making it a compelling option for this unique patient population.

Perampanel as only add-on epilepsy treatment in elderly: A subgroup analysis of real-world data from retrospective, multicenter, observational study.

INTRODUCTION: Drug management of epilepsy in the elderly presents unique but data on this population are scarce. This study aimed to assess the effectiveness and tolerability of perampanel (PER) used as only add-on to a background anti-seizure medication (ASM) in the elderly in a real-world setting. METHODS: We performed a subgroup analysis of patients aged ≥65 years included in a previous 12-month multicenter study on adults. Treatment discontinuation, seizure frequency, and adverse events were recorded at 3, 6 and 12 months after PER introduction. Sub-analyses by early (≤1 previous ASM) or late PER add-on were also conducted. RESULTS: The sample included 65 subjects (mean age: 75.7 ± 7.2 years), with mainly focal (73.8%) epilepsy. The mean PER daily dose was ≈4 mg during all follow-up. Retention rates at 3, 6, and 12 months were 90.5%, 89.6%, and 79.4%ly. The baseline median normalized per 28-day seizure number significantly decreased at 3-, 6- and 12-month visits. One year after PER introduction, the responder rate (≥50% reduction in baseline seizure frequency) was 89.7%, with a seizure freedom rate of 72.4%. Adverse events occurred in 22 (34.9%) patients with dizziness and irritability being the most frequent. No major differences between early (41 patients, 63.1%), and late add-on groups were observed. CONCLUSION: Adjunctive PER was effective and well-tolerated when used as only add-on treatment in elderly people with epilepsy in clinical practice, thus representing a suitable therapeutic option in this age category.

Home Pulse Pressure Predicts Death and Cardiovascular Events in Peritoneal Dialysis Patients.

Increased arterial hypertension represents a prevalent condition in peritoneal dialysis patients that is often related to volume expansion. Pulse pressure is a robust predictor of mortality in dialysis patients, but its association with mortality is unknown in peritoneal patients. We investigated the relationship between home pulse pressure and survival in 140 PD patients. During a mean follow-up of 35 months, 62 patients died, and 66 experienced the combined event death/CV events. In a crude COX regression analysis, a five-unit increase in HPP was associated with a 17% increase in the hazard ratio of mortality (HR: 1.17, 95% CI 1.08-1.26 p < 0.001). This result was confirmed in a multiple Cox model adjusted for age, gender, diabetes, systolic arterial pressure, and dialysis adequacy (HR: 1.31, 95% CI 1.12-1.52, p = 0.001). Similar results were obtained considering the combined event death-CV events as an outcome. Home pulse pressure represents, in part, arterial stiffness, and it is strongly related to all-cause mortality in peritoneal patients. In these high cardiovascular risk populations, it is important to maintain optimal blood pressure control, but it is fundamental to consider all the other cardiovascular risk indicators, such as pulse pressure. Home pulse pressure measurement is easy and feasible and can add important information for the identification and management of high-risk patients.

Competitive interaction between smoking and chronic obstructive pulmonary disease for explaining renal function reduction in hypertensive patients.

Chronic kidney disease is a risk factor for cardiovascular events. Smoking and chronic obstructive pulmonary disease (COPD) are risk factors for renal impairment. The aim of this study was to test the combined effect of smoking and COPD on renal function decline in hypertensives. We enrolled 1728 hypertensives stratified by smoking status and presence/absence of COPD. To test the mutual effect modification by both smoking and COPD and e-GFR, we performed crude and adjusted linear regression analyses, these latter taking into account potential confounders. Smokers displayed significantly lower e-GFR values than non-smokers (90 ± 24 vs. 121 ± 35 ml/min/1.73 m2); this difference was confirmed when comparing e-GFR values between patients with/without COPD (81 ± 17 vs. 109 ± 32 ml/min/1.73 m2). Smoking and COPD were directly and significantly interrelated (Cramer's V coefficient = 0.200; P = < 0.001). At interaction analyses, smoking significantly modified the effect of COPD on e-GFR and COPD significantly modified the effect of smoking on e-GFR, indicating a competitive interaction between smoking and COPD in the appearance of renal damage. e-GFR was 35 ml/min/1.73 m2 lower in patients with COPD than in those without; this reduction was of higher magnitude than that found between COPD and COPD-free patients among smokers (19 ml/min/1.73 m2). Smoking and COPD competitively interact in the appearance of renal function decline. These results suggest to screen for kidney damageboth smokers and COPD patients, especially those with both conditions.

Comparative Effectiveness of Combined IgM-Enriched Immunoglobulin and Extracorporeal Blood Purification Plus Standard Care Versus Standard Care for Sepsis and Septic Shock after Cardiac Surgery.

Background: The combination of surgery, bacterial spread-out, and artificial cardiopulmonary bypass surfaces results in a release of key inflammatory mediators leading to an overshooting systemic hyper-inflammatory condition frequently associated with compromised hemodynamics and organ dysfunction. A promising approach could be extracorporeal blood purification therapies in combination with IgM enriched immunoglobulin. This approach might perform a balanced control of both hyper and hypo-inflammatory phases as an immune-modulating intervention. Methods: We performed a retrospective observational study of patients with proven infection after cardiac surgery between January 2020 and December 2021. Patients were divided into two groups: (1) the first group (Control Group) followed a standard care approach as recommended by the Surviving Sepsis Campaign Guidelines; The second group (Active Group) underwent extracorporeal blood purification therapy (EBPT) in combination with intravenous administration of IgM enriched immunoglobulin 5 mL/kg die for at least three consecutive days, in conjunction with the standard approach (SSC Guidelines). In addition, ventriculo-arterial (V/A) coupling, Interleukin 6 (IL-6), Endotoxin Activity Assay (EAA), Procalcitonin, White Blood Cells (WBC) counts, Sequential Organ Failure Assessment (SOFA) Score and Inotropic Score were assessed in both two groups at different time points. Results: Fifty-four patients were recruited; 25 were in the Control Group, while 29 participants were in the Active Group. SOFA score significantly improved from baseline [12 (9-16)] until at T 3 [8 (3-13)] in the active group; it was associated with a median EAA reduction from 1.03 (0.39-1.20) at T 0 to 0.41 (0.2-0.9) at T 3 in the active group compared with control group 0.70 (0.50-1.00) at T 0 to 0.70 (0.50-1.00) at T 3 (p < 0.001). V/A coupling tended to be lower in patients of the active arm ranging from 1.9 (1.2-2.7) at T 0 to 0.8 (0.8-2.2) at T 3 than in those of the control arm ranging from 2.1 (1.4-2.2) at T0 to 1.75 (1.45-2.1) at T 3 (p = 0.099). The hemodynamic improvement over time was associated with evident but no significant decrease in inotropic score in the active group compared with the control group. Changes in EAA value from T 0 to T 4 were directly and significantly related (r = 0.39, p = 0.006) to those of V/A coupling. Conclusions: EBPT, in combination with IgM enriched immunoglobulin, was associated with a mitigated postoperative response of key cytokines with a significant decrease in IL-6, Procalcitonin, and EAA and was associated with improvement of clinical and metabolic parameters.
