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

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.

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.

Multiple sclerosis and pregnancy: a single-centre prospective comparative study. / Esclerosis múltiple y embarazo: estudio unicéntrico prospectivo y comparativo.

INTRODUCTION: Multiple sclerosis (MS) is a autoimmune disorder which preferentially affects young women of childbearing age. During pregnancy, the annualized relapse rate (AAR) is modified, but pregnancy has no harm effect on the long-term course of the disease. We aimed to study the clinical course of our MS patients during pregnancy, and compare their obstetrics outcomes with a control group of non-MS patients. METHODS: A single centre prospective observational study was conducted. We assessed the reproductive history, MS history, pregnancy course and new-born outcome of a cohort of MS patients who had had a pregnancy between january 2007 and july 2012. We compared the global outcomes with a control cohort of 58 age-matched healthy pregnancies. RESULTS: Complete data from 35 consecutive women were analyzed, 40 deliveries. Control groups: 58 patients, 60 deliveries. EDSS at pregnancy 0,7. ARR before pregnancy 0,5. During pregnancy 0,3, after pregnancy 0,4. Twelve patients were on disease-modifying drugs (DMD) before pregnancy, 4 prenatal exposure occurs. The comparison between relapse rate and EDSS before, during and after delivery showed no statistically significant difference. In addition, compared to control group, there were also no differences in the obstetric outcomes. In MS cohort, we found a higher incidence of assisted reproductive treatments and lower breastfeeding rate, both statistically significant. CONCLUSIONS: Our series confirms that pregnancy has no negative long term impact on the progression of MS and also suggest that there is no additional morbidity in the pregnancy, comparing to the rest of the population.

Spontaneous spinal epidural haematoma: a retrospective study of a series of 13 cases.

INTRODUCTION: Spontaneous spinal epidural haematoma (SSEH) has an estimated incidence of one per million inhabitants. It is classified as spontaneous when no identifiable cause can be linked to its onset. OBJECTIVE: To describe a sample of patients with SSEH and analyse variables related to its functional prognosis. PATIENTS AND METHODS: Retrospective study carried out in patients diagnosed with SSEH between 2001 and 2013 in our hospital. RESULTS: We included 13 subjects (7 men) with a mean age of 71 years. Of the total, 62% had hypertension and 54% were treated with oral anticoagulants; of the latter, 57% had an International Normalised Ratio above 3. The most frequent manifestation was spinal column pain (85%). Nearly all subjects presented an associated neurological deficit, whether sensory-motor (70%), pure motor (15%), or pure sensory (7%). Five patients underwent surgical treatment and 8 had conservative treatment. After one year, 3 of the patients treated surgically and 4 of those on conservative treatment had a score of 2 or lower on the modified Rankin Scale. Poorer prognosis was observed in patients with anticoagulant therapy, large haematomas, location in the lumbar region, and more pronounced motor disability at onset. CONCLUSIONS: Old age, hypertension, and anticoagulant therapy are the main risk factors for SSEH. The typical presentation consists of back pain with subsequent motor deficit. In patients with established motor symptoms, surgical treatment within the first 24hours seems to be the best option.

Workload of on-call emergency room neurologists in a Spanish tertiary care centre. A one-year prospective study.

INTRODUCTION: Population ageing, the rising demand for healthcare, and the establishment of acute stroke treatment programs have given rise to increases in the number and complexity of neurological emergency cases. Nevertheless, many centres in Spain still lack on-call emergency neurologists. METHODS: We conducted a retrospective study to describe the role of on-call neurologists at Hospital General Universitario Gregorio Marañón, a tertiary care centre in Madrid, Spain. Sociodemographic characteristics, most common pathologies, diagnostic tests, and destination of the patients attended were recorded daily using a computer database. Results were compared with the general care data from the emergency department. RESULTS: The team attended 3234 patients (3.48% of the emergency department total). The mean number of patients seen per day was 11.15. The most frequent pathologies were stroke (34%), epilepsy (16%) and headache (8%). The mean stay in the emergency department was 7.17 hours. Hospital admission rate was 40% (7.38% of emergency hospital admissions). The main destinations for admitted patients were the stroke unit (39.5%) and the neurology department (33%). Endovascular or thrombolytic therapies were performed on 76 occasions. Doctors attended 70% of the patients during on-call hours. CONCLUSIONS: Emergency neurological care is varied, complex, and frequently necessary. Neurological cases account for a sizeable percentage of both patient visits to the emergency room and the total number of emergency admissions. The current data confirm that on-call neurologists available on a 24-hour basis are needed in emergency departments.
