Plasmaféresis periódica como tratamiento de mantenimiento en la esclerosis múltiple remitente-recurrente, ¿nueva línea terapéutica? A propósito de un caso / Periodic plasmapheresis as maintenance treatment in relapsing-remitting multiple sclerosis, a new therapeutic line? A case report

Introducción: El tratamiento de la esclerosis múltiple remitente-recurrente ha evolucionado significativamente en los últimos años con el descubrimiento de nuevas moléculas eficaces como tratamiento de mantenimiento. Por otro lado, el tratamiento de los brotes de esta enfermedad se basa clásicamente en corticoides, y en los casos refractarios a esta terapia se utiliza plasmaféresis. Presentamos un caso de esclerosis múltiple remitente-recurrente tratada periódicamente con una terapia que se ha utilizado clásicamente para los brotes: plasmaféresis. Caso clínico: Mujer de 39 años con esclerosis múltiple remitente-recurrente de inicio en el posparto, gran carga lesional y curso agresivo, en quien, ante una respuesta subóptima a terapias modificadoras de la enfermedad (alemtuzumab y ocrelizumab), se decide iniciar un tratamiento combinado junto con plasmaféresis periódicas ambulatorias cada tres semanas como tratamiento de mantenimiento. Se constata una buena tolerancia a esta terapia y evolución, y se produce estabilidad clínica. No ha requerido nuevos ingresos hospitalarios por brotes desde febrero de 2020 a marzo de 2021. Conclusión: Aunque es necesario que se realicen más estudios, este caso ofrece información sobre un potencial tratamiento de mantenimiento para pacientes con esclerosis múltiple remitente-recurrente refractaria a terapias con fármacos modificadores de la enfermedad.(AU)

Introduction: Relapsing-remitting multiple sclerosis (RRMS) treatment has significantly changed in recent years because of the discovery of new molecules that have shown efficacy as maintenance treatment. However, the classical treatment for acute attacks is based on corticosteroids administration, being the periodical plasmapheresis the alternative treatment in the case of refractory patients. We introduce a case of relapsing-remitting multiple sclerosis treated with a classical acute attacks therapy: plasmapheresis. Case report: The case of a 39-year-old patient who was diagnosed with relapsing-remitting multiple sclerosis, postpartum debut and aggresive course, who, after suboptimal response to disease modifying therapies (alemtuzumab and ocrelizumab), receives combination treatment with outpatient periodic plasmapheresis every 3 weeks as maintenance therapy. Good tolerance and response. Clinical stability with this treatment. She has not required new hospital admissions for acute attacks of multiple sclerosis from February 2020 to March 2021. Conclusion: Although more specific studies are needed, this case provides information on a potential new maintenance treatment for patients with relapsing-remitting multiple sclerosis refractory to disease-modifying drug therapies.(AU)

Neurofilament light chain levels in pregnant multiple sclerosis patients: a prospective cohort study.

BACKGROUND AND PURPOSE: Neurofilament light chain is a cytoskeletal protein of neurons. Its levels are increasingly recognized as measures of neuroaxonal damage. The aim of this study was to explore serum neurofilament light chain (sNfL) levels in multiple sclerosis (MS) patients and healthy controls during pregnancy and puerperium. METHODS: This was a prospective, longitudinal, single-center study. sNfL concentration was assessed using a highly sensitive single-molecule array during pregnancy and in puerperium, in a cohort of 39 pregnant patients with relapsing multiple sclerosis (P-MS). Twenty-one healthy pregnant women (HPW) served as a control group. Eight P-MS suffered relapses during pregnancy (P-MS-R) in the first or second trimesters. RESULTS: No differences in pregnancy and delivery data were observed between P-MS and HPW. P-MS showed higher sNfL values than HPW in the first trimester, independently of the presence (P = 0.002) or not (P = 0.02) of relapses during pregnancy. However, in the third trimester, only P-MS-R showed higher sNfL values than HPW (P = 0.001). These differences extended to the puerperium, where P-MS-R showed higher sNfL values than those with no relapses during gestation (P = 0.02). CONCLUSION: These data strongly suggest that sNfL levels reflect MS activity during pregnancy. Additionally, the absence of relapses during pregnancy may have a beneficial effect on neurodegeneration during puerperium.

Endovascular treatment of cerebral venous sinus thrombosis (CVST): Is a complete recanalization required for a good clinical outcome?

The usual therapy in cerebral venous sinus thrombosis (CVST) is based on anticoagulant treatment with adjusted-dose unfractionated heparin. When medical treatment fails, endovascular techniques, such as mechanical thrombectomy, are available. We report a case of a 21-year-old woman with a diagnosis of left CVST, treated by a neurointerventional approach with mechanical thrombectomy using the Penumbra(®) System. Despite the fact that only incomplete recanalization was achieved, a gradual resolution of the thrombus and a progressive clinical improvement occurred.
