Headache is one of the most prevalent, although often underreported, symptoms of coronavirus disease 2019 (COVID-19). It is generally accepted that this symptom is a form of secondary headache due to systemic viral infection. There are several hypotheses that try to explain its aetiopathogenesis. One of the most compelling is related to innate immune response to viral infection. This rationale is supported by similarities to other viral infections and the temporal overlap between immunological reactions and headache. Moreover, several key factors in innate immunity have been shown to facilitate headache e.g. interferons, interleukin (IL) -1-β, IL-6, and tumour necrosis factor. There is also a possibility that the virus causes headache by the direct activation of afferents through pattern recognition receptors (i.e. Toll-like receptor 7). Moreover, some data on post-COVID-19 headache and after vaccination against SARS-CoV-2 infection suggests a similar cytokine-mediated pathomechanism in these clinical situations. Future research should look for evidence of causality between particular immune response factors and headache. Identifying key molecules responsible for headache during acute viral infection would be an important step towards managing one of the most prevalent secondary headache disorders.

Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system (CNS) that mostly manifests as irreversible disability. The aetiopathogenesis of MS is still unclear, although it was initially thought to be primarily mediated by T-cells. Research into the immune concepts of MS pathophysiology in recent years has led to a shift in the understanding of its origin i.e. from a T-cell-mediated to a B-cell-mediated molecular background. Thus, the use of B-cell-selective therapies, such as anti- -CD20 antibody therapy, as expanded therapeutic options for MS is now strongly supported. This review provides an up-to-date discussion on the use of anti-CD20 targeted therapy in MS treatment. We present a rationale for its use and summarise the results of the main clinical trials showing the efficacy and safety of rituximab, ocrelizumab, ofatumumab, and ublituximab. Future directions that show selectivity to a broader population of lymphocytes, such as the use of anti-CD19 targeted antibodies, as well as the concept of extended interval dosing (EID) of anti-CD20 drugs, are also discussed in this review.

Aim of the study: To evaluate the long-term retention rate, efficacy, and tolerability of adjunctive cenobamate (CNB) in patients with drug-resistant epilepsy within the Polish Expanded Access Programme (EAP).

Clinical rationale for the study: Long-term retention rate is a useful measure of effectiveness including efficacy, safety, and tolerability of antiseizure medications.

Material and methods: We conducted a multicentre retrospective analysis of consecutive patients with focal epilepsy treated with CNB in the EAP between January 2020 and May 2023. All patients who completed the open-label extension phases of the YKP3089C013 and YKP3089C017 trials were offered the opportunity to continue CNB treatment within the EAP. We analysed cenobamate retention, seizure outcomes, and adverse events.

Results: 38 patients (18 females; 47.3%) continued CNB treatment within the Expanded Access Programme for 41 months. The mean baseline age of patients was 39.3 years (range: 18-57). All patients were on polytherapy, with the most commonly used antiseizure medications being valproate, levetiracetam, and carbamazepine. Adjunctive CNB treatment resulted in a reduced mean seizure frequency from 8.1 seizures (range: 4-20) per month to 3 seizures (range: 0-8) per month. At the final follow-up, the median CNB dose was 200 mg/day (range: 50-350). Among the patients, 24 (63.1%) achieved ≥ 50% seizure reduction, and eight (21%) remained seizure-free for at least 12 months. One in three patients experienced adverse events, which resolved in half of the subjects. The most frequent adverse events were dizziness, somnolence, and headache. The retention rate after completing the open-label extension phase was 100%.

Conclusions and clinical implications: Long-term effectiveness, including ≥ 50% seizure reduction and a 100% retention rate, was sustained over 41 months of CNB treatment within the Expanded Access Programme. No new safety issues were identified. These results provide support for the potential long-term clinical benefits of cenobamate.

Introduction: Pompe disease is a rare, autosomal recessive, lysosomal disorder caused by deficiency of alpha glucosidase (GAA). It leads to the accumulation of glycogen in body tissues, with severe myopathy and cardiomegaly as a hallmark of the classic infantile form. Non-classical, or late onset, Pompe disease (LOPD) manifests after 12 months of age or in adulthood.

Material and methods: The clinical heterogeneity of LOPD causes delay in diagnosis and pharmacological treatment. In the Polish population, it is still underdiagnosed, and the time from onset to diagnosis remains a cause for concern.

Clinical implications: Although typically patients present with proximal muscle weakness, high CK or early respiratory insufficiency, they can also suffer from multiple symptoms from other organs. Patients may present with arrhythmias, vascular abnormalities including aneurysms or dilative arteriopathy, gastric or urinary symptoms, or musculoskeletal pathologies.

Results: A high index of suspicion among neurologists consulting internal medicine wards would aid early diagnosis of LOPD, while a multidisciplinary approach with the involvement of other specialists can reduce the risk of complications and improve the prognosis for LOPD patients. Patients who manifest with musculoskeletal and respiratory symptoms are prone to be diagnosed sooner than individuals with non-muscular symptoms, and therefore it is important to raise awareness of other manifestations of this disease.

Stroke remains one of the greatest health challenges worldwide, due to a high mortality rate and, despite great progress in its treatment, the significant disability that it causes. Studies conducted around the world show that the diagnosis of stroke in children is often significantly delayed. Paediatric ischaemic arterial stroke (PAIS) is not only a problem that varies greatly in frequency compared to the adult population, it is also completely different in terms of its risk factors, clinical course and outcome. The main reason for the lack of a rapid diagnosis of PAIS is a lack of access to neuroimaging under general anaesthesia. The insufficient knowledge regarding PAIS in society as a whole is also of great importance. Parents and carers of children should always bear in mind that paediatric age is not a factor that excludes a diagnosis of stroke. The aim of this article was to develop recommendations for the management of children with acute neurological symptoms suspected of ischaemic stroke and further treatment after confirmation of the ischaemic aetiology of the problem. These recommendations are based on current global recommendations for the management of children with stroke, but our goal was also to match them as closely as possible to the needs and technical diagnostic and therapeutic possibilities encountered in Poland. Due to the multifactorial problem of stroke in children, not only paediatric neurologists but also a neurologist, a paediatric cardiologist, a paediatric haematologist and a radiologist took part in the preparation of these recommendations.
