Association of anticardiolipin antibodies with epilepsy in children

We investigated the association of anticardiolipin antibodies (aCL) with epilepsy development and characteristics in children. This prospective case-control study included 40 epileptic children and 40 sex- and age-matched controls. Epileptic children had higher levels of aCL compared to healthy controls (5.66 ± 5.41 versus 2.37 ± 2.28; p value = 0.001). The novel finding of elevated levels of aCL predicted response to IVIg therapy (p value = 0.009). Patients with normal EEG had lower levels of aCL compared to those with EEG abnormal findings (p value = 0.015). Patients with the combined type of epilepsy had statistically significant higher levels of aCL compared to other types (p value = 0.046). Also, aCL levels were correlated with seizure frequency (p value = 0.019). These results declare the possible involvement of such antibodies in the onset or pathogenesis of epilepsy. Screening for aCL may help in the timely diagnosis of epilepsy and initiation of appropriate treatment.

Relations between antinuclear, antineutrophil cytoplasmic, anticardiolipin antibodies and degree of neurological deficit, cerebrovascular stenosis in cerebral infarction patients

Objective

To investigate the correlation of antinuclear antibody (ANA), antineutrophil cytoplasmic antibody (ANCA) and anticardiolipin antibody (ACA) with the degree of the neurological defect and cerebrovascular stenosis in patients with cerebral infarction.

Methods

Clinical data of 99 patients with acute cerebral infarction (ACI) admitted to the Department of Neurology of Baoding First Central Hospital from June 2020 to December 2021 were retrospectively analyzed, and their ANA, ACA, ANCA, neurological deficit (NIHSS) scores as well as cerebrovascular stenosis were detected and assessed. Moreover, the correlation between the positive expression rates of ANA, ANCA, ACA and the degree of the neurological deficit, as well as the location and degree of cerebrovascular stenosis, were analyzed.

Results

All patients had ANA, ACA, ANCA antibodies with positive rates of 68.69%, 70.71%, 69.70%, and mild, moderate, and severe cerebrovascular stenosis with incidence rates of 28.28%, 32.32%, and 39.39% respectively; Moreover, their incidence of mild, moderate, and severe neurological deficits were 15.15%, 44.44%, and 40.40%, respectively. Statistically significant differences could be observed in the degree of cerebrovascular stenosis and neurological deficit between the ANA, ACA and ANCA antibody positive group and the negative group (p<0.05). ANA, ACA, ANCA antibody positive was moderately positively correlated with cerebrovascular stenosis rate and NIHSS score (0.40

Conclusions

The positive rates of ANA, ACA and ANCA antibodies were higher in patients with ACI, which was closely correlated with the degree of cerebrovascular stenosis and neurological deficit.
