Medication-resistant acute focal motor seizures in a child with COVID-19 affecting the CNS

A perfectly healthy preschool girl presented with acute repetitive focal aware motor seizures, while her brain MRI showed a lesion in the left posterior cortex. After a number of investigations, her cerebrospinal fluid PCR was positive for SARS-CoV-2. Despite receiving at least four anti-seizure medications at appropriate dosages, the seizures continued, and just after administering intravenous immunoglobulin, her seizures stopped. This dramatic response to intravenous immunoglobulin may indicate a hypothetical inflammatory process in the patient's cortex caused by COVID-19.

Frequency of Toxoplasma and Toxocara Sp. Antibodies in Epileptic Patients, in South Western Iran.

OBJECTIVE: Epilepsy is a disorder of the brain characterized by an enduring predisposition to generate seizures. Infectious agents are mentioned in its etiology. With identifying and appropriate treatment of these infectious agents, preventing their secondary outcomes, including seizure is possible. This study was conducted to determine frequency of anti-Toxoplasma antibodies (IgG, IgM) and anti-Toxocara antibody (IgG) in epileptic patients. MATERIALS & METHODS: Study sample consisted of 141 epileptic patients and 144 healthy people. After obtaining informed consents and completing demographic questionnaire, serum samples were taken from participants. The diagnostic test of Toxoplasma IgG & IgM and Toxocara antibodies was performed under the same conditions using ELISA method in a qualified private laboratory. Samples from patients and control groups with positive ELISA test in terms of anti-Toxocara antibody were also used for confirmatory Western blot test. RESULT: According to ELISA results, 28 (19.85%) epileptic patients and 2(1.38%) of healthy people had anti-Toxocara antibodies (P<001), while 39 (30.46%) of the control group people and 14.18% of patients had anti-Toxoplsma antibodies (P=0.001). CONCLUSION: Frequency of anti-Toxoplasma gondii is lower in epileptic than healthy individuals and this result is contrary to investigations that have reported higher levels of this antibody in such patient groups. ELISA results for Toxocara showed that the frequency of anti-Toxocara antibody in epileptic patients might empower the probability that this parasite may cause central nervous system damage. Western blotting has high specificity and is a proper confirmative method for diagnosis of toxocariasis.
