RESUMEN

Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative central nervous system (CNS) disorder, characterized by focal inflammation, demyelination, irreversible axonal loss and neurodegeneration. The proposed mechanism involves auto-reactive T lymphocytes crossing the blood-brain barrier (BBB), contributing to inflammation and demyelination. Pro-inflammatory Th1 and Th17 lymphocytes are pivotal in MS pathogenesis, highlighting an imbalanced interaction with regulatory T cells. Dysbiosis in the gut microbiota, characterized by microbial imbalance is implicated in systemic inflammation, yet its exact role in MS remains elusive. Short-chain fatty acids (SCFAs), including valerate, butyrate, propionate, and acetate, produced through dietary fiber fermentation by the gut microbiota, modulate inflammation and immune responses. Particularly, butyrate and propionate exhibit pronounced anti-inflammatory effects in both the gut and CNS. These SCFAs influence regulatory T lymphocyte expression and BBB permeability. This review discusses the potential therapeutic implications of SCFA in MS, highlighting their ability to modulate the gut-brain axis and restore immune balance.

RESUMEN

Background and Objectives: Considering the fact that prematurity echoes in terms of motor development even up to the age of adolescence, through the presence of deficiencies, the importance of starting kinetotherapeutic treatment as soon as possible is highlighted, even in the absence of brain damage or obvious motor delays. Therefore, the objectives of this study are to analyze the factors that influence the level of motor development of premature babies up to 9 months and identify the motor development curve of premature babies according to the three stages of motor development: the position of symmetrical support on the elbows at 3 months, sitting with support at 6 months, and verticalization at 9 months. Materials and Methods: This prospective pilot study was conducted within a rehabilitation facility located in Targu Mureș, Romania, spanning a duration of 2 years from June 2021 to 2023. Results: The study involved a population of 78 children, all premature infants, selected from the patient pool of the rehabilitation facility, specifically chosen based on adherence to the predetermined inclusion and exclusion criteria outlined in the study protocol. Two physiotherapists specialized in child recovery were involved in the study, and one performed the assessments and the other applied the Bobath therapy. Conclusions: Early physiotherapy interventions can have a positive influence in terms of reducing differences in motor development between preterm and full-term infants. This study identified several factors that influence the motor development of premature infants. Among these, the most prominent biological factors were gestational age and birth weight.

RESUMEN

Background and Objectives: Torticollis is a common pediatric condition, with an incidence of 0.3-2.0%. Studies show that an adequate, tailored, and early treatment helps 90% to 95% of children recover before the first year of life and 97% of patients recover if treatment starts before the first six months. To identify the relationships between variables considered essential in the recovery process of infants with torticollis, we included factors such as the type of torticollis, age at onset of treatment, gender, birth weight, mode of delivery, fetal position in the uterus, the presence of craniofacial deformities, regions affected by postural asymmetries, and duration of the rehabilitation program. The hypothesis of the study is that early initiation of therapy can contribute to achieving favorable outcomes in the recovery process. Material and Methods: This retrospective cohort pilot study was conducted within a rehabilitation facility, spanning a duration of 1 year. The study involved a population of 41 children aged between 0 and 6 months. The rehabilitation program consisted of the application of Vojta therapy. Each session lasted 20 min, with a frequency of three times per week. Results: A total of 41% of those who started therapy in the first 3 months of life were fully recovered after 4-6 weeks of therapy. Of infants who started therapy at 5 and 6 months of age, 15% showed no improvement in measurements from 14 to 16 weeks of age, at which point the use of a cranial orthosis was recommended, and 23% experienced a plateau in measurements from 10 to 14 weeks, requiring the use of a cervical collar in conjunction with therapy. Conclusions: The findings from the study suggest that there may be a correlation between early initiation of therapy and favorable outcomes in the recovery process. The primary factors influencing the duration of recovery were identified as the presence of body asymmetries and the age at which therapy was initiated.

RESUMEN

Neurological disorders have been linked to a defective blood-brain barrier (BBB), with dysfunctions triggered by stage-specific disease mechanisms, some of these being generated through interactions in the neurovascular unit (NVU). Advanced knowledge of molecular and signaling mechanisms in the NVU and the emergence of improved experimental models allow BBB permeability prediction and the development of new brain-targeted therapies. As NVU constituents, astrocytes are the most numerous glial cells, characterized by a heterogeneity that occurs as a result of developmental and context-based gene expression profiles and the differential expression of non-coding ribonucleic acids (RNAs). Due to their heterogeneity and dynamic responses to different signals, astrocytes may have a beneficial or detrimental role in the BBB's barrier function, with deep effects on the pathophysiology of (and on the progression of) central nervous system diseases. The implication of astrocytic-derived extracellular vesicles in pathological mechanisms, due to their ability to pass the BBB, must also be considered. The molecular mechanisms of astrocytes' interaction with endothelial cells at the BBB level are considered promising therapeutic targets in different neurological conditions. Nevertheless, a personalized and well-founded approach must be addressed, due to the temporal and spatial heterogeneity of reactive astrogliosis states during disease.

RESUMEN

Despite extensive research into the pathophysiology of multiple sclerosis (MS) and recent developments in potent disease-modifying therapies (DMTs), two-thirds of relapsing-remitting MS patients transition to progressive MS (PMS). The main pathogenic mechanism in PMS is represented not by inflammation but by neurodegeneration, which leads to irreversible neurological disability. For this reason, this transition represents a critical factor for the long-term prognosis. Currently, the diagnosis of PMS can only be established retrospectively based on the progressive worsening of the disability over a period of at least 6 months. In some cases, the diagnosis of PMS is delayed for up to 3 years. With the approval of highly effective DMTs, some with proven effects on neurodegeneration, there is an urgent need for reliable biomarkers to identify this transition phase early and to select patients at a high risk of conversion to PMS. The purpose of this review is to discuss the progress made in the last decade in an attempt to find such a biomarker in the molecular field (serum and cerebrospinal fluid) between the magnetic resonance imaging parameters and optical coherence tomography measures.

RESUMEN

Background: In infants presenting with motor development impairment, early kinesiotherapeutic interventions aim to normalise the pattern of movements and improve recovery. By applying Bobath and Vojta methods, we aimed to identify a combined approach regarding motor deficit in infants with neurological disabilities. Methods: We designed a prospective interventional study on 108 infants with motor developmental delay and applied Bobath, Vojta, or combined Bobath and Vojta therapy in three equal groups. Results: In the combined Bobath and Vojta group, complete motor recovery was achieved for 50% of the participants, with full recovery after six months, whereas in Bobath- or Vojta-only therapy groups, the total recovery for all participants was achieved at seven months. Regarding infants with muscular hypertonia, Bobath therapy initiation demonstrated complete recovery in 5 months in more than 50% of the cases, while for Vojta this was achieved in only 33.57% of the cases. Conclusions: The comparative evaluation conducted by analysing the data regarding the application of the Bobath and Vojta methods showed that combining these two therapies results in a shorter motor deficit recovery time than if a single therapy is applied. These findings have important implications for the selection of rehabilitation therapies in infants with neurological motor development issues.

RESUMEN

Amyotrophic lateral sclerosis (ALS) is a grievous neurodegenerative disease whose survival is limited to only a few years. In spite of intensive research to discover the underlying mechanisms, the results are fairly inconclusive. Multiple hypotheses have been regarded, including genetic, molecular, and cellular processes. Notably, oxidative stress has been demonstrated to play a crucial role in ALS pathogenesis. In addition to already recognized and exhaustively studied genetic mutations involved in oxidative stress production, exposure to various environmental factors (e.g., electromagnetic fields, solvents, pesticides, heavy metals) has been suggested to enhance oxidative damage. This review aims to describe the main processes influenced by the most frequent genetic mutations and environmental factors concurring in oxidative stress occurrence in ALS and the potential therapeutic molecules capable of diminishing the ALS related pro-oxidative status.

RESUMEN

Stroke is the primary cause of disability in the adult population. Hypertension represents the leading risk factor being present in almost half the patients. The renin-angiotensin system is involved in the physiopathology of stroke and has an essential impact on hypertension as a risk factor. This article targeted the role of the renin-angiotensin system in stroke neuroprotection by reviewing the current literature available. The mechanism of action of the renin-angiotensin system was observed through the effects on AT1, AT2, and Mas receptors. The neuroprotective properties ascertained by angiotensin in stroke seem to be independent of the blood pressure reduction mechanism, and include neuroregeneration, angiogenesis, and increased neuronal resistance to hypoxia. The future relationship of stroke and the renin-angiotensin system is full of possibilities, as new agonist molecules emerge as potential candidates to restrict the impairment caused by stroke.

RESUMEN

Cladribine (CLD) treats multiple sclerosis (MS) by selectively and transiently depleting B and T cells with a secondary long-term reconstruction of the immune system. This study provides evidence of CLD's immunomodulatory role in peripheral blood mononuclear cells (PBMCs) harvested from 40 patients with untreated relapsing-remitting MS (RRMS) exposed to CLD. We quantified cytokine secretion from PBMCs isolated by density gradient centrifugation with Ficoll−Paque using xMAP technology on a FlexMap 3D analyzer with a highly sensitive multiplex immunoassay kit. The PBMC secretory profile was evaluated with and without CLD exposure. PBMCs isolated from patients with RRMS for ≤12 months had significantly higher IL-4 but significantly lower IFN-γ and TNF-α secretion after CLD exposure. PBMCs isolated from patients with RRMS for >12 months had altered inflammatory ratios toward an anti-inflammatory profile and increased IL-4 but decreased TNF-α secretion after CLD exposure. CLD induced nonsignificant changes in IL-17 secretion in both RRMS groups. Our findings reaffirm CLD's immunomodulatory effect that induces an anti-inflammatory phenotype.

RESUMEN

The disruption of blood-brain barrier (BBB) for multiple sclerosis (MS) pathogenesis has a double effect: early on during the onset of the immune attack and later for the CNS self-sustained 'inside-out' demyelination and neurodegeneration processes. This review presents the characteristics of BBB malfunction in MS but mostly highlights current developments regarding the impairment of the neurovascular unit (NVU) and the metabolic and mitochondrial dysfunctions of the BBB's endothelial cells. The hypoxic hypothesis is largely studied and agreed upon recently in the pathologic processes in MS. Hypoxia in MS might be produced per se by the NVU malfunction or secondary to mitochondria dysfunction. We present three different but related terms that denominate the ongoing neurodegenerative process in progressive forms of MS that are indirectly related to BBB disruption: progression independent of relapses, no evidence of disease activity and smoldering demyelination or silent progression. Dimethyl fumarate (DMF), modulators of S1P receptor, cladribine and laquinimode are DMTs that are able to cross the BBB and exhibit beneficial direct effects in the CNS with very different mechanisms of action, providing hope that a combined therapy might be effective in treating MS. Detailed mechanisms of action of these DMTs are described and also illustrated in dedicated images. With increasing knowledge about the involvement of BBB in MS pathology, BBB might become a therapeutic target in MS not only to make it impenetrable against activated immune cells but also to allow molecules that have a neuroprotective effect in reaching the cell target inside the CNS.

RESUMEN

Stroke represents the primary debilitating disease in adults and is the second-highest cause of death worldwide. Atherosclerosis, the most prevalent etiology for vascular conditions, is a continuous process that gradually creates and develops endothelial lesions known as atherosclerotic plaques. These lesions lead to the appearance of atherothrombotic stroke. In the last decades, the role of biological biomarkers has emerged as either diagnostic, prognostic, or therapeutic targets. This article aims to create a list of potential biomarkers related to atherothrombotic stroke by reviewing the currently available literature. We identified 23 biomarkers and assessed their roles as risk factors, detection markers, prognostic predictors, and therapeutic targets. The central aspect of these biomarkers is related to risk stratification, especially for patients who have not yet suffered a stroke. Other valuable data are focused on the predictive capabilities for stroke patients regarding short-term and long-term prognosis, including their influence over the acute phase treatment, such as rt-PA thrombolysis. Although the role of biomarkers is anticipated to be of extreme value in the future, they cannot yet compete with traditional stroke neuroimaging markers but could be used as additional tools for etiological diagnosis.

RESUMEN

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disorder affecting neuromuscular transmission. Exacerbations may involve increasing bulbar weakness and/or sudden respiratory failure, both of which can be critically disabling. Management of MG exacerbations includes plasma exchange and intravenous immunoglobulin (IVIG); they are equally effective, but patients experience fewer side effects with IVIG. The objective of this study was to assess the efficacy and safety of immune globulin caprylate/chromatography purified (IGIV-C) in subjects with MG exacerbations. METHODS: This prospective, open-label, non-controlled 28-day clinical trial was conducted in adults with MG Foundation of America class IVb or V status. Subjects received IGIV-C 2 g/kg over 2 consecutive days (1 g/kg/day) and were assessed for efficacy/safety on Days 7, 14, 21, and 28. The primary efficacy endpoint was the change from Baseline in quantitative MG (QMG) score to Day 14. Secondary endpoints of clinical response, Baseline to Day 14, included at least a 3-point decrease in QMG and MG Composite and a 2-point decrease in MG-activities of daily living (MG-ADL). RESULTS: Forty-nine subjects enrolled. The change in QMG score at Day 14 was significant (p < 0.001) in the Evaluable (-6.4, n = 43) and Safety (-6.7, n = 49) populations. Among evaluable subjects, Day 14 response rates were 77, 86, and 88% for QMG, MG Composite, and MG-ADL, respectively. IGIV-C showed good tolerability with no serious adverse events. CONCLUSIONS: The results of this study show that IGIV-C was effective, safe, and well tolerated in the treatment of MG exacerbations.

RESUMEN

BACKGROUND: Cardiac autonomic neuropathy (CAN) in diabetes is among the strongest risk markers for future global and cardiovascular mortality. The aim of this study was to analyse CAN prevalence and to compare the associations between CAN, the glycaemic control, cardiovascular risk factors, peripheral neuropathy, retinopathy and macroangiopathy in patients with type 1 (T1DM) and type 2 diabetes mellitus (T2DM). METHODS: One hundred ninety-five diabetic patients were included in this study. All patients were evaluated for detection of CAN (with standardised cardiovascular reflex tests), diabetes-related microvascular complications (polyneuropathy, retinopathy), common carotid artery intima-media thickness (IMT) and ankle-brachial index (ABI). RESULTS: The prevalence of CAN was 39.1% in T2DM and 61.8% in T1DM patients. Multivariate logistic regression analysis demonstrated that in T2DM, the odds [OR (95% confidence intervals)] of CAN increased with diabetes duration [1.67(1.42-1.92)], HbA1c [1.74(1.34-2.27)], cholesterol [1.01(1.00-1.01)], triglycerides [1.01(0.99-1.00)], smoking [2.35(1.23-4.49)], systolic blood pressure [1.01(1.00-1.03)], BMI [1.16(1.08-1.24)], glomerular filtration rate [0.91(0.88-0.93)], peripheral neuropathy [25.94(11.04-44.25)], retinopathy [13.13(3.03-84.73)] and IMT [10.12 (7.21-15.32)]. In T1DM, the odds of CAN increased with diabetes duration [1.62(1.13-2.31)], HbA1c [4.49(1.27-15.9)], age of patients [1.14(1.03-1.27)], glomerular filtration rate [0.94(0.89-0.99)], peripheral neuropathy [31.6(4.5-45.8)] and IMT [5.5(2.3-8.3)]. CONCLUSION: This study indicated that CAN is a more frequent complication in T1DM. Apart from glycaemic control, the existence of CAN is associated with potentially modifiable cardiovascular risk only in T2DM patients. The presence of other micro- and macrovascular complications increases the probability of having CAN in both types of DM (but more pronounced in T2DM).

RESUMEN

In cerebral ischemia, evaluation of multiple biomarkers involved in various pathological pathways is a useful tool in assessing the outcome of the patients even from the early stages of the disease. In this study we investigated the utility of a panel of 5 peripheral biomarkers of inflammatory status, neuronal destruction and secondary fibrinolysis in the acute phase of ischemia, and evaluated the impact of these biomarkers on functional outcome after ischemic stroke. The 5 biomarkers (plasma CRP, D-Dimers, sTNFR-1, NGAL and NSE) were measured using a biochip array technology. Eighty nine patients in Romania were divided into 2 subgroups using the modified Rankin Scale evaluated at 3 months after ischemic stroke; the possible impact of analyzed biomarkers on unfavorable functional outcome was tested by binomial logistic regression. The subgroup with unfavorable outcome had higher concentrations of CRP, NGAL, sTNFR-1 and D-dimers, but CRP and NGAL values were not statistically different between the two subgroups. The univariate logistic regression analysis of plasma biomarkers revealed that CRP, D-Dimers, NGAL, sTNFR-1 were significant predictors of unfavorable clinical outcome. In the case of D-Dimers and sTNFR-1 we noticed an increased discrimination ability (versus baseline clinical model) to classify poor functional outcome with a tendency toward statistical signification. During the acute phase of the ischemic stroke, plasma concentrations of CRP, D-Dimers and sTNFR-1 were elevated in unfavorable outcome patients. D-Dimers and sTNFR-1 were independent predictors of poor outcome at 3 months after ischemic stroke. The biochip array technology offers the possibility to simultaneously measure several parameters involved in multiple pathophysiological pathways, in a small sample volume.

RESUMEN

A 57-year-old patient was admitted to the Neurology Clinic for hypoesthesia, intense pain in the right chin and double vision. During the hospitalization, the patient developed progressive complete bilateral ophthalmoplegia and numbness of both sides of the chin. Brain CT and MRI scans with gadolinium were normal. Standard laboratory tests on admission were normal. The cerebral spinal fluid examination and the infectious and autoimmune workup were also normal. A thoracic-abdominal and pelvic CT scan revealed two hypodense lesions in the liver, irregular thickening of the gastric and ileal wall, and multiple abdominal adenopathies. Meanwhile, the patient developed marked fatigue, fever, sweats, nausea, vomiting and abdominal pain. An exploratory laparotomy was performed that showed multiple tumours of the small intestinal wall, stomach wall, multiple liver masses in both lobes and appendicular tumour. Histopathological findings of the liver biopsy and appendicular walls revealed Burkitt lymphoma. The patient died two days after surgery by cardiopulmonary arrest. This case underscores the importance of keeping BL in the differential diagnosis of patients with rapidly progressive ophthalmoplegia and numb chin syndrome, with normal brain MRI and CSF examinations.

RESUMEN

Temporal arteritis (TA), also known as giant cell arteritis, is a chronic vasculitis of medium and large-sized blood vessels, in particular the main cervical branches of the aorta, with particular affinity to the temporal arteries and eye-supplying arteries. Temporal artery biopsy is still a gold standard for diagnosis, however in recent years colour duplex ultrasound examination has been proposed as a useful diagnostic screening tool in cases of TA suspicion. We report three cases of TA in which the ultrasonographical examination of the temporal arteries had a decisive role in the diagnosis.

RESUMEN

Background: Multiple sclerosis (MS) is a prevalent chronic inflammatory and neurodegenerative disease of the central nervous system. The main evolving forms, relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS), lack clear delineation. Methods: We conducted an observational study on 523 Caucasian RRMS patients receiving first-line disease-modifying therapies (DMTs), analyzing demographic, clinical, and geographical data. Results: RRMS patients experienced a statistically significant reduction in relapse rates post-DMT initiation. Significant differences in time to reach an Expanded Disability Status Score (EDSS) of 3.0 and 6.0 were observed based on demographics and onset topography. Kaplan-Meier analysis revealed that the onset with optic or supratentorial symptoms is linked to a longer time until EDSS = 3.0 is reached. Urban origin correlated with a prolonged time until EDSS = 3.0. Gender and environment showed no significant associations with the hazard of reaching an EDSS = 6.0. Cox regression analysis revealed no significant impact of relapses on the time to reach EDSS scores of 3.0 and 6.0 in our study cohort. Conclusions: Multivariate analysis identified several predictive factors for disability progression, including environment, age at onset, and disability level at DMT initiation.

RESUMEN

BACKGROUND: Interleukin-17 (IL-17), which is secreted by Th17 cells, is a proinflammatory cytokine that is implicated in the pathogenesis of multiple sclerosis (MS) and plays a role in nonresponse of MS patients to interferon-ß (IFN-ß) therapy. OBJECTIVES: The purpose of this study was to establish a correlation between nonresponders (NR) and IL-17A serum titers and binding antibodies (BAbs) to IFN-ß, as well as to find a correlation between IL-17A serum levels and other features of MS patients. METHODS: Our prospective study included 72 inactive relapsing-remitting multiple sclerosis (RRMS) patients that had been treated for at least 18 months with IFN-ß and 15 healthy subjects. We determined the serum levels of IL-17A and of BAbs. IL-17A levels were considered elevated (IL-17A+) if the recorded value was greater than 1.6 pg/ml. RESULTS: Twenty-seven patients (37.5%) were NR and had a significantly higher serum IL-17A level compared to the responders group. Nineteen patients (26.4%) were IL-17A+ and had had a significantly higher number of relapses in the previous year and a higher Expanded Disability Status Score. The majority of IL-17A+ patients were NR and had a shorter MS duration. CONCLUSIONS: RRMS patients with high serum IL-17A levels do not respond well to IFN-ß therapy and have shorter MS duration compared to patients with low IL-17A levels. This response is not influenced by the presence of BAbs.

RESUMEN

BACKGROUND: A limited subgroup of multiple sclerosis (MS) patients present with a long-term disease evolution characterized by a limited disease progression, known as benign MS (BMS). Chitinase 3-like-1 (CHI3L1) levels are sensitive to inflammatory processes and may play a role in the pathogenesis of MS. In this observational, cross-sectional study, we aimed to evaluate the implications of serum CHI3L1 and inflammatory cytokines in BMS patients treated with interferon ß-1b for over a decade. METHODS: We collected serum samples from 17 BMS patients and 17 healthy controls (HC) to measure serum CHI3L1 levels and a Th17 panel of inflammatory cytokines. Serum levels of CHI3L1 were analysed using the sandwich ELISA method and the Th17 panel was assessed using the multiplex XMap technology on a Flexmap 3D Analyzer. RESULTS: Serum CHI3L1 levels did not differ significantly from HC. We identified a positive correlation between CHI3L1 levels and relapses during treatment. CONCLUSIONS: Our findings suggest that there are no differences in serum CHI3L1 levels between BMS patients and HC. However, serum CHI3L1 levels are sensitive to clinical inflammatory activity and may be associated with relapses in BMS patients.

RESUMEN

Electrical injuries are relatively common types of mechanical trauma associated with significant morbidity and mortality. These injuries occur most commonly in adult men and account for approximately 3-7% of admissions to burn units. The type and amount of current, voltage, tissue resistance, and duration of current flow all influence the extent of injury and the patient outcome. A broad spectrum of central nervous system (CNS) and peripheral nervous systems (PNS) disorders caused by electrocution have been described in the literature. Here, we present a rare case of a 45-year-old man, electrocuted with a 240 V low-voltage alternating current (AC), four years prior to presentation, who has been admitted to our neurology clinic with a positive Lhermitte sign, paraparesis, proximal muscle pain, and distal paresthesia of the lower limbs, symptoms that had appeared one year after the electrocution. Magnetic resonance imaging (MRI) of the brain and spinal cord revealed multiple demyelinating lesions involving pons, juxtacortical and periventricular regions of the brain, and cervical and upper thoracic spinal cord. Given that other etiologies of demyelinating diseases of the CNS were excluded, we have interpreted this case and all accompanying pathologic findings as a consequence of electrical injury. Although the general epidemiologic reports regarding age, sex, type of current, circumstances, and site of electrocution correspond to the data of our reported case, this patient presents a delayed, rare neurologic complication with a nonspecific MRI pattern that we did not find in the literature. These patients should be carefully monitored not only during the acute phase but also over a longer period, because, as reported in this case, neurological complications may occur later after electrocution.
