cTnI, BNP and CRP profiling after seizures in patients with drug-resistant epilepsy.
To profile serum levels of high sensitivity Troponin I (hs-cTnI), B-Type Natriuretic Peptide (BNP), and high sensitivity C Reactive Protein (hs-CRP), after epileptic seizures in patients with focal drug-resistant epilepsy, relating the results to the revised SUDEP-7 inventory.. We prospectively evaluated patients admitted to our Epilepsy Monitoring Unit. hs-cTnI, BNP, and hs-CRP were measured at admission and after the first seizure. The revised SUDEP-7 Risk Inventory was calculated. The statistical significance level was set at 0.05.. Fifty-eight patients were included (53.4 % female). The index seizure was a focal to bilateral tonic-clonic seizure (FBTCS) in 25.9 % of the patients, and 17.5 % had post-ictal generalized EEG suppression (PGES). After the seizure, 25.9 % had a significant (above 50 %) increase in hs-cTnI, 23.3 % in BNP, and 4.3 % in hs-CRP. About 40 % had cardiovascular risk factors (CRF), without known cardiac disease. The elevation of one biomarker did not compel the elevation of another. hs-cTnI increase was associated with FBTCS, PGES, longer seizures, maximal ictal heart rate, and HR change. Increases in BNP were associated with CRF. hs-CRP increase was associated with PGES. We found no significant association between SUDEP-7 and any biomarker increase.. Several patients had increases in biomarkers of myocardial necrosis/dysfunction after seizures, without significant association with the SUDEP-7 inventory. Different patterns of biomarkers' elevations point to multifactorial pathophysiologies hypothetically associated with incipient myocardial lesions. A larger cohort with follow-up data could help to clarify the clinical relevance of these findings.

Blood markers of cardiac stress after generalized convulsive seizures.
Generalized convulsive seizures (GCS) are associated with high demands on the cardiovascular system, thereby facilitating cardiac complications. To investigate occurrence, influencing factors, and extent of cardiac stress or injury, the alterations and time course of the latest generation of cardiac blood markers were investigated after documented GCS.. Adult patients with refractory epilepsy who underwent video-electroencephalography (EEG) monitoring along with simultaneous one-lead electrocardiography (ECG) recordings were included. Cardiac biomarkers (cardiac troponin I [cTNI]; high-sensitive troponin T [hsTNT]; N-terminal prohormone of brain natriuretic peptide [NT-proBNP]; copeptin; suppression of tumorigenicity-2 [SST-2]; growth differentiation factor 15, [GDF-15]; soluble urokinase plasminogen activator receptor [suPAR]; and heart-type fatty acid binding protein [HFABP]) and catecholamines were measured at inclusion and at different time points after GCS. Periictal cardiac properties were assessed by analyzing heart rate (HR), HR variability (HRV), and corrected QT intervals(QTc).. Thirty-six GCS (6 generalized-onset tonic-clonic seizures and 30 focal to bilateral tonic-clonic seizures) were recorded in 30 patients without a history of cardiac or renal disease. Postictal catecholamine levels were elevated more than twofold. A concomitant increase in HR and QTc, as well as a decrease in HRV, was observed. Elevations of cTNI and hsTNT were found in 3 of 30 patients (10%) and 6 of 23 patients (26%), respectively, which were associated with higher dopamine levels. Copeptin was increased considerably after most GCS, whereas SST-2, HFABP, and GDF-15 displayed only subtle variations, and suPAR was unaltered in the postictal period. Cardiac symptoms did not occur in any patient.. The use of more sensitive biomarkers such as hsTNT suggests that signs of cardiac stress occur in about 25% of the patients with GCS without apparent clinical symptoms. SuPAR may indicate clinically relevant troponin elevations. Copeptin could help to diagnose GCS, but specificity needs to be tested.

Serum N-Terminal Pro-B-Type Natriuretic Peptide (NTproBNP) Levels Are Elevated During the Acute Phase of Acute Encephalopathy-Associated Virus Infection.
Acute virus-associated encephalopathy induces seizures. Serum N-terminal pro-B-type natriuretic peptide (NTproBNP) levels are elevated following febrile and afebrile seizures. However, the role of NTproBNP in acute virus-associated encephalopathy pathology is unknown. We enrolled 10 patients with acute virus-associated encephalopathy and convulsions (E group: 7 boys, 3 girls; median age, 3.10 ± 1.92 years) and 130 patients with febrile seizure (FS group: 80 boys, 50 girls; median age, 3.23 ± 2.44 years). The E group had significantly higher NTproBNP levels (345 ± 141 pg/mL) compared with the FS group (166 ± 228 pg/mL) (P < .0005). Furthermore, subjects with prolonged seizure within the E group had significantly higher NTproBNP levels (303 ± 107 pg/mL) compared with subjects with prolonged seizure within the FS group (134 ± 100 pg/mL) (P < .005). Our findings suggest that serum NTproBNP levels are increased during the acute phase of acute virus-associated encephalopathy associated with convulsion.

Elevated CK-MB mass and plasma brain-type natriuretic peptide concentrations following convulsive seizures in children and adolescents: possible evidence of subtle cardiac dysfunction.
To evaluate the presence of myocardial injury during convulsive seizures in children and adolescents by determining serum concentrations of cardiac troponin I (cTnI), creatine kinase-MB mass (CK-MB mass), and plasma brain-type natriuretic peptide (BNP).. Thirty-one children (20 boys; mean age, 6.6 +/- 5.34 years) with convulsive seizures and 50 healthy children were enrolled. Serum cTnI, CK-MB mass, and plasma BNP concentrations were analyzed 12 h after the seizure and repeated 7 days thereafter in the patient group and obtained one time in the control group.. The difference between serum concentrations of cTnI obtained 12 h and 7 days after the seizure was not statistically significant. cTnI levels 12 h postictal and those in control subjects also were not significantly different. CK-MB mass and BNP at the 12th h were higher than those obtained on the 7th day (p < 0.05 and p < 0.001, respectively). Children with seizures had increased levels of CK-MB mass and BNP 12 h after seizure than control subjects (p < 0.05 and p < 0.001, respectively). The results of electrocardiography (ECG) recordings, which were obtained up to 30 min after seizure activity, were completely normal in patients with seizure.. Normal cTnI levels are not indicative of overt myocardial necrosis in patients with seizures. However, markedly elevated BNP concentrations together with elevated CK-MB mass levels do suggest subtle cardiac dysfunction in patients with seizure, and further large-scale studies are warranted.

Brain-type natriuretic peptide release and seizure activity during vagal nerve stimulation.
Vagus nerve stimulation (VNS) has emerged as an effective adjunctive therapy for medically refractory epilepsy when surgery is inadvisable. N-terminal brain-type natriuretic peptide (NT-proBNP) is a potent natriuretic, diuretic, and vasodilatative compound first discovered in the human brain but mainly synthesized in the myocardium. The monitoring of VNS effectiveness in reducing seizure frequency or the detection of possible cardiac adverse effects would be helped by a reliable biochemical marker, which has not been available thus far. We report a four-year-old boy with drug-resistant idiopathic generalized epilepsy whose NT-proBNP levels increased during VNS and seizures.
