[PMID: 40253903 DOI: 10.1016/j.msard.2025.106446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2024] [Revised: 04/09/2025] [Accepted: 04/12/2025] [Indexed: 04/22/2025]
Abstract
OBJECTIVE The purpose of this study was to analyze the utility of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in pediatric myelin-oligodendrocyte glycoprotein antibody-associated disease (MOGAD). METHODS Retrospective review of medical record was performed to analyze association among complete blood count (CBC) indices and clinical characteristics of pediatric MOGAD patients. RESULTS 61 patients were included in the analysis. In 24 subjects with matched CBC samples, NLR, PLR, and monocyte-to-lymphocyte ratio (MLR) were higher during disease relapse than in remission. In the receiver operating characteristics (ROC) curve analysis, the optimal cutoff values were 2.55 and 179.4 for NLR and PLR, respectively. The area under curve (AUC) was 0.809 and 0.658 for NLR and PLR, respectively. At disease onset, NLR and PLR were higher in patients in the relapsing group. In the ROC curve analysis, the optimal cutoff values were 3.35 and 183.8 with the AUC of 0.739 and 0.700 for NLR and PLR, respectively. In logistic regression analysis, NLR and PLR elevation were statistically significant after adjusting for age, sex, and phenotype. The pooled analysis of all clinical attacks in the relapsing group revealed that NLR and PLR are lower in the isolated optic neuritis (ON) compared to the other phenotypes. CONCLUSION This study shows that in pediatric MOGAD patients, NLR and PLR are useful for prompt recognition of disease relapse and prediction of relapsing course at disease onset. NLR and PLR are also associated with clinical phenotypes in pediatric MOGAD.

Abstract
Multiple sclerosis (MS) is the most common demyelinating disease caused by a multifaceted interplay of genetic predispositions and environmental factors. Most patients initially experience the relapsing-remitting form of the disease (RRMS), which is characterized by episodes of neurological deficits followed by periods of symptom resolution. However, over time, many individuals with RRMS advance to a progressive form of the disease, known as secondary progressive MS (SPMS), marked by a gradual worsening of symptoms without periods of remission. The mechanisms underlying this transition remain largely unclear, and current disease-modifying therapies (DMTs) are partially effective in treating SPMS. Age is widely acknowledged as a risk factor for the transition from RRMS to SPMS. One factor associated with aging that may influence the progression of MS is gut dysbiosis. This review discusses how aging and age-related gut dysbiosis affect the progression of MS.

Abstract
BACKGROUND Urolithiasis is among the most prevalent and possibly devastating diseases. It affects millions worldwide, and a cheap or rapid biomarker is required to diagnose it. Previous investigations revealed that inflammation has a role in the progression of urolithiasis patients, and an elevated neutrophil-to-lymphocyte ratio (NLR) value can be a valuable biomarker to ensure inflammation and, consequently, renal stones. This study was conducted to summarize the results of studies investigating the role of NLR in urolithiasis. METHODS We systematically searched three main databases (Scopus, PubMed, and Web of Science) up to January 1, 2023. Our study was registered in PROSPERO (CRD42024500756). RESULTS Ultimately, 33 studies were selected for this review article. Patients in either acute or subacute phase exhibited higher NLR levels than healthy controls. Also, patients in acute and subacute phases significantly differed regarding NLR levels. In addition, studies showed that NLR could predict sepsis and systemic inflammatory response syndrome (SIRS) among urolithiasis patients. In addition, evidence reported that NLR was helpful in the prediction of spontaneous stone passage among these patients. CONCLUSION Our results support a reliable biomarker that is easily added into clinical settings to help predict urolithiasis patients' condition.

Abstract
Introduction Multiple sclerosis (MS) is a chronic and debilitating inflammatory disease of the central nervous system (CNS), characterized by demyelination and neurodegeneration. Emerging evidence implicates neutrophils in MS pathogenesis, particularly through processes like neutrophil extracellular traps (NETs) formation and degranulation, which may exacerbate inflammation and autoimmunity. Methods RNA sequencing of peripheral blood neutrophils from MS patients and healthy controls identified differentially expressed genes (DEGs). Pathway enrichment and protein-protein interaction (PPI) analyses highlighted potential biomarkers, validated using reverse transcription quantitative PCR (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA). Results Our analysis identified 1,968 DEGs in neutrophils from MS patients, comprising 1,068 upregulated and 900 downregulated genes. Pathway enrichment analysis revealed significant involvement of immune processes, including antigen presentation, B and T cell receptor signaling, intracellular signaling cascades, and neutrophil degranulation. Notably, KEGG analysis highlighted a pivotal role for upregulated genes in neutrophil extracellular traps (NETs) formation, a process increasingly associated with autoimmunity. PPI network analysis pinpointed five key hub genes-LCN2, LTF, ELANE, CAMP, and CTSG-as central players in neutrophil-mediated immune modulation. Protein-level validation using ELISA confirmed elevated levels of LCN2, ELANE, CAMP, and CTSG, consistent with transcriptomic findings, further supporting their role as biomarkers. Subsequent RT-qPCR validation demonstrated robust diagnostic potential for these genes, with area under the curve (AUC) values of 0.952 (LCN2), 0.827 (LTF), 0.968 (ELANE), 0.950 (CAMP), and 0.862 (CTSG). Discussion These findings uncover a previously underappreciated role for neutrophils in MS pathogenesis, driven by alterations in gene expression linked to immune modulation and NET formation. The identified biomarkers, particularly ELANE and LCN2, demonstrate strong diagnostic potential, offering a new avenue for non-invasive MS diagnostics. Beyond clinical utility, this study highlights the importance of neutrophil-driven immune responses in MS, providing mechanistic insights into the complex interplay between innate and adaptive immunity in demyelinating diseases. Furthermore, these findings suggest that targeting neutrophil-specific processes, such as NETs formation and degranulation, could mitigate inflammatory damage and provide novel therapeutic approaches for MS treatment. These results lay the groundwork for future studies exploring therapeutic strategies targeting neutrophil functions in MS.

Abstract
Complete blood count (CBC)-derived indices have been proposed as reliable inflammatory biomarkers to predict outcomes in the context of coronary artery disease. These indices have yet to be thoroughly validated in patients with intermediate coronary stenosis. Our study included 1527 patients only with intermediate coronary stenosis. The examined variables were neutrophil-lymphocyte ratio (NLR), derived NLR, monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR), systemic immune inflammation index (SII), system inflammation response index (SIRI), and aggregate index of systemic inflammation (AISI). The primary endpoint was the composite of major adverse cardiovascular events (MACEs), including all-cause death, non-fatal myocardial infarction, and unplanned revascularization. Over a follow-up of 6.11 (5.73-6.55) years, MACEs occurred in 189 patients. Receiver operator characteristic curve analysis showed that SIRI outperformed other indices with the most significant area under the curve. In the multivariable analysis, SIRI (hazard ratio [HR] 1.588, 95% confidence interval [CI] 1.138-2.212) and AISI (HR 1.673, 95% CI 1.217-2.300) were the most important prognostic factors among all the indices. The discrimination ability of each index was strengthened in patients with less burden of modifiable cardiovascular risk factors. SIRI also exhibited the best incremental value beyond the traditional cardiovascular risk model.

Abstract
Multiple Sclerosis (MS) is a complex auto-inflammatory disease affecting the brain and spinal cord, which results in axonal de-myelination and symptoms including fatigue, pain, and difficulties with vision and mobility. The involvement of the immune system in the pathology of MS is well established, particularly the adaptive T cell response, and there has been a particular focus on the IL-17-producing subset of Th17 cells and their role in driving disease. However, the importance of innate immune cells has not been so well characterized. Here we focussed on neutrophils, which are innate immune cells and rapid responders to inflammation, and which have recently been linked to other chronic autoimmune conditions. Multiple strands of evidence in patients with MS and in mice with the experimental autoimmune encephalomyelitis MS model suggest neutrophils may play a role in driving MS inflammation. Here, we performed proteomic analysis on neutrophils from patients with MS and healthy donors, revealing striking differences. In particular, granule proteins were significantly more abundant in the MS neutrophils compared to the healthy controls, with a particular overabundance of proteins in primary and secondary granules. In addition, members of the MAVS signalling pathway were differently regulated compared to healthy donor cells. Finally, we find that MS neutrophils do not suppress T cell activation equivalently to healthy neutrophils, and in particular are unable to suppress expression of CD161 on the T cells, indicative of a suppression of Th17 differentiation. We propose that neutrophil dysregulation in MS may contribute to dysfunctional T cell responses.

Abstract
BACKGROUND Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is a heterogeneous entity with either a monophasic or relapsing course. Well-established predictors of relapsing disease are lacking. OBJECTIVE Identifying predictors of relapsing MOGAD, particularly at disease onset. METHODS A multicentre observational retrospective study was conducted to characterise a cohort of Portuguese adult MOGAD patients. Patients were identified from participating centre databases. Clinical and demographic data were collected from medical records. Bivariate analysis was conducted to compare patients with relapsing and monophasic MOGAD. Significant variables were included in a stepwise multiple regression analysis to identify independent predictors of relapse. RESULTS Eighty-seven MOGAD patients from 8 public hospitals were included. Relapsing MOGAD was found in 35.6% (n = 31). Mean diagnostic delay was 3.2 (±6.2) years and time to relapse was 4.4 (±6.4) years. Multiple logistic regression showed that higher neutrophil count (p < 0.01), presence of oligoclonal bands (p = 0.025) and no bridging corticosteroids (p = 0.038) at first attack were predictive of relapsing MOGAD. CONCLUSION Neutrophil count and oligoclonal bands at first attack may facilitate early decision-making regarding maintenance immunotherapy. Bridging corticosteroids may also influence the course of MOGAD. Further studies with prospective design are warranted.

Abstract
Early neuroinflammatory injury plays a crucial role in initiating and progressing multiple sclerosis (MS). Neutrophils are forerunners to neural lesions in MS, yet the temporal alterations of their functions in MS remains unclear. This study demonstrated a positive correlation between circulatory neutrophil counts and disease activity and severity in treatment-naïve MS patients. In experimental autoimmune encephalomyelitis (EAE), we documented the recruitment of neutrophils to spinal cord during the preclinical phase, with these cells contributing to the disruption of the blood-spinal cord barrier (BSCB) during the onset of the disease. Furthermore, during the peak phase, infiltrated neutrophils promoted demyelination through formation of neutrophil extracellular traps (NETs), cytokine secretion and antigen presentation. Notably, the inhibition of neutrophil infiltration using a CXCR2 inhibitor effectively mitigated white matter damage and physical disability, underscoring their potential as therapeutic targets. In conclusion, neutrophils represent promising candidates for both disease treatment and prognosis evaluation in MS. By elucidating their temporal roles and mechanisms of action, we can potentially harness their modulation to improve patient outcomes and disease management.

Abstract
Background and Objectives: Traumatic spinal cord injury (SCI) is a devastating condition that occurs in two phases: primary and secondary injury. These phases contribute to changes in blood vessels and the influx of inflammatory cells such as neutrophils and lymphocytes. The biomarker known as the neutrophil-to-lymphocyte ratio (NLR) has been suggested as being highly valuable in predicting outcomes for patients with traumatic brain injury, acute ischemic stroke, and traumatic spinal cord injury. Therefore, this review study aims to investigate the prognostic value of the NLR in predicting outcomes for patients with SCI. Materials and Methods: A thorough review of relevant articles was conducted using Mesh keywords in Medline via Embase, PubMed, Google Scholar, and Scopus from 2000 to 2023. The search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. After reviewing the articles and applying inclusion and exclusion criteria, only relevant articles were included in the study. Results: In the initial search, 41 papers were identified. After applying exclusion criteria, only three clinical studies remained for review. It is still debatable whether the NLR can serve as a cost-effective, readily available, and independent predictive factor for both mortality and recovery outcomes in patients with traumatic spinal cord injuries. Conclusions: Our study demonstrates that NLR, a readily available and inexpensive marker, can serve as an independent predictor of both mortality and recovery outcomes in patients with traumatic spinal cord injury. To reach a conclusive decision, additional data are required.

Li Z, Lu Q. The role of neutrophils in autoimmune diseases. Clin Immunol 2024; 266:110334. [PMID: 39098706 DOI: 10.1016/j.clim.2024.110334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2024] [Revised: 07/26/2024] [Accepted: 07/27/2024] [Indexed: 08/06/2024]
Abstract
Historically, neutrophils have been primarily regarded as short-lived immune cells that act as initial responders to antibacterial immunity by swiftly neutralizing pathogens and facilitating the activation of adaptive immunity. However, recent evidence indicates that their roles are considerably more complex than previously recognized. Neutrophils comprise distinct subpopulations and can interact with various immune cells, release granular proteins, and form neutrophil extracellular traps. These functions are increasingly recognized as contributing factors to tissue damage in autoimmune diseases. This review comprehensively examines the physiological functions and heterogeneity of neutrophils, their interactions with other immune cells, and their significance in autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, antiphospholipid syndrome, antineutrophil cytoplasmic antibody-associated vasculitis, multiple sclerosis, and others. This review aims to provide a deeper understanding of the function of neutrophils in the development and progression of autoimmune disorders.

Abstract
Previous studies have validated a close association between inflammatory factors and multiple sclerosis (MS), but their causal relationship is not fully profiled yet. This study used Mendelian randomization (MR) to investigate the causal effect of circulating inflammatory proteins on MS. Data from a large-scale genome-wide association study (GWAS) were analyzed using a two-sample MR method to explore the relationship between 91 circulating inflammatory proteins and MS. The inverse-variance-weighted (IVW) analysis was employed as the main method for evaluating exposures and outcomes. Furthermore, series of the methods of MR Egger, weighted median, simple mode, and weighted mode were used to fortify the final results. The results of the IVW method were corrected with Bonferroni (bon) and false discovery rate (fdr) for validating the robustness of results and ensuring the absence of heterogeneity and horizontal pleiotropy. The sensitivity analysis was also performed. The results of the forward MR analysis showed that higher levels of CCL25 were found to be associated with an increased risk of MS according to IVW results, OR: 1.085, 95% CI (1.011, 1.165), p = 2.42 × 10-2, adjusted p_adj_bon = 1, p_adj_fdr = 0.307. Similarly, higher levels of CXCL10 were found to be associated with an increased risk of MS, OR: 1.231, 95% CI (1.057, 1.433), p = 7.49 × 10-3, adjusted p_adj_bon = 0.682, p_adj_fdr = 0.227. In contrast, elevated levels of neurturin (NRTN) were associated with a decreased risk of MS, OR: 0.815, 95% CI (0.689, 0.964), p = 1.68 × 10-2, adjusted p_adj_bon = 1, p_adj_fdr = 0.307. Reverse MR analysis showed no causal relationship between MS and the identified circulating inflammatory cytokines. The effects of heterogeneity and level pleiotropy were further excluded by sensitivity analysis. This study provides new insights into the relationship between circulating inflammatory proteins and MS and brings up a new possibility of using these cytokines as potential biomarkers and therapeutic targets. The data in this study show that there are only weak associations between inflammatory molecules and MS risk, which did not survive bon and fdr correction, and the obtained p-values are quite low. Therefore, further studies on larger samples are needed.

Abstract
INTRODUCTION Biomarkers that help to evaluate the immune system and could be useful in multiple sclerosis (MS) are the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and systemic immune-inflammatory index (SII). The objective of this work is to evaluate the significance of the SII index, PLR, and NLR before and after transplantation in individuals with MS who underwent autologous hematopoietic stem cell transplant (aHSCT) at a single institution. METHODS Patients with MS who received an aHSCT between 2017 and 2022 were included in the study. NLR, PLR, and SII index were calculated prior to the transplant and 100 days after, and evaluation of the expanded disability status scale (EDSS) was done before the transplant and 12 months after. The cohort was divided into two groups: aHSCT responders (R) and nonresponders (NR). RESULTS Fifty-eight individuals were examined: 37 patients in the responders group R group and 21 in NR group. There was no statistically significant difference in the SII, NLR, and PLR prior to the transplant, however at 100 days post-HSCT, NLR in the R group was 1.8 versus 3.1 in the NR group (p = 0.003), PLR was 194 versus 295, respectively (p = 0.024), meanwhile SII index was 489.5 versus 729.3 (p < 0.001). CONCLUSION High NLR and SII index values after the aHSCT were associated with a worsening in the EDSS score. However, since this is the first ever study that compared NLR and SII index with the aHSCT response in persons with MS, further studies must be performed to corroborate this information.

Abstract
Multiple sclerosis (MS) is a prevalent neuroimmunological illness that leads to neurological disability in young adults. Although the etiology of MS is heterogeneous, it is well established that aberrant activity of adaptive and innate immune cells plays a crucial role in its pathogenesis. Several immune cell abnormalities have been described in MS and its animal models, including T lymphocytes, B lymphocytes, dendritic cells, neutrophils, microglia/macrophages, and astrocytes, among others. Physical exercise offers a valuable alternative or adjunctive disease-modifying therapy for MS. A growing body of evidence indicates that exercise may reduce the autoimmune responses triggered by immune cells in MS. This is partially accomplished by restricting the infiltration of peripheral immune cells into the central nervous system (CNS) parenchyma, curbing hyperactivation of immune cells, and facilitating a transition in the balance of immune cells from a pro-inflammatory to an anti-inflammatory state. This review provides a succinct overview of the correlation between physical exercise, immune cells, and MS pathology, and highlights the potential benefits of exercise as a strategy for the prevention and treatment of MS.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) are inflammatory biomarkers that may predict disease course in neuroinflammatory diseases. We examine whether NLR or MLR at the time of the first attack predicts longitudinal disease outcomes in pediatric neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS). METHODS Clinical data were collected retrospectively at a single institution. NLR (ratio of percent neutrophils to percent lymphocytes) and MLR (ratio of percent monocytes to percent lymphocytes) were calculated in the complete blood cell count at the time of presentation before treatments. Expanded Disability Status Scale (EDSS) score and time to next relapse were used as the outcome assessments. RESULTS Twenty-eight patients with MS and eight patients with aquaporin-4-positive NMOSD were included. For NMOSD, NLR at presentation associated with EDSS at six months (P = 0.003) and one year (P = 0.032) even when adjusting for age at presentation. MLR associated with EDSS at six months (P = 0.0203) and EDSS at one year (P = 0.0079). However, NLR and MLR did not predict EDSS scores in MS. MLR and NLR did not predict time to next relapse or did not associate with magnetic resonance imaging activity in MS and NMOSD. Changes in MLR and NLR were observed with disease-modifying therapies but did not predict disease activity. CONCLUSIONS NLR and MLR associated with six-month and one-year EDSS in children with NMOSD but not in MS. Future studies should explore whether changes in NLR and MLR could predict disease activity or treatment efficacy.

Abstract
In addition to cellular and humoral immunity, inflammatory markers play an important role in the pathogenesis of Guillain-Barré syndrome (GBS) and are used to predict prognosis in many autoimmune diseases. The aim of this study was to identify whether the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, and monocyte-lymphocyte ratio in the early stages of GBS have prognostic value for severe disease, mechanical ventilation (MV) and poor long-term outcome. A prospective cohort study of 140 adult patients with GBS and 140 healthy controls (HC) was performed in Bangladesh during 2019-2022. Clinicodemographic characteristics of the patients were recorded, and hematological parameters were measured using an automated hematology analyzer. Median patient age was 35 (44-23) years; 71% were male; 88% were severely affected (GBS Disability Score> 3); 32% required MV. Patients had higher NLR than HC (P< .0001). Among patients, elevated NLR was associated with severe GBS and MV (P= .001 and <.0001, respectively) and moderately positively correlated with poor outcomes at 4 weeks (r = 0.423). Multiple logistic regression revealed NLR was an independent risk factor for severe GBS (OR = 5.2, 95% CI = 1.6-17.4) and MV (OR = 1.5 1.1-2.1). No significant association was observed between elevated NLR and the long-term outcome of GBS. Receiver operating characteristic curves revealed NLR cut-off values of ≥ 2.432 and ≥ 4.4423 predicted severe disease (sensitivity = 71%, specificity = 75%, AUC = 0.750, 95% CI = 0.651-0.849, P = .001) and MV (sensitivity = 65.9%, specificity = 81.7%, AUC = 0.804, 95% CI=0.724-0.884; P< .001). The NLR in the early stage of GBS may represent an independent prognostic factor of severe GBS and the requirement for MV.

Abstract
Background The neutrophil-to-lymphocyte ratio (NLR) may predict poor outcomes in adult anti-NMDAR encephalitis (NMDARE). The association of NLR with outcomes in pediatric NMDARE was examined. Methods Pediatric NMDARE patients (N = 36) were retrospectively studied. Results High NLR (>6) had a higher proportion of tumors (43% versus 7%) and higher intubation rates (100% versus 38%, p = 0.008). Multivariate analyses showed that high NLR did not correlate with one-year outcomes, inpatient length of stay (LOS), or with tumor, but was associated with intubation and rehabilitation LOS. Conclusion NLR is associated with intubation and rehabilitation LOS. Further investigation is needed for prognostic biomarkers in NMDARE.

Abstract
BACKGROUND Multiple sclerosis (MS) is an immune-mediated chronic disease characterized by inflammatory demyelination in the central nervous system (CNS).As there is limited evidence on whether leukocyte-to-lymphocyte ratios (LLRs) are associated with MS, we carried out an investigation on the association between LLRs and MS as favorable markers and aimed to determine the cut-off LLR for the identification of early-stage MS patients. METHODS A matched case-control study enrolled a total of 120 MS inpatients and 120 age- and sex-matched non-MS inpatients from January 2013 to June 2018. LLRs were tested from peripheral venous blood routinely during hospitalization. Conditional logistic regression analyses were used to explore differences in LLRs between cases and controls. Receiver operating characteristic (ROC) curve analysis was performed to assess the diagnostic ability of LLRs and determine the best cut-off value. Disease disability was assessed using the Expanded Disability Status Scale (EDSS). RESULTS The LLR was significantly associated with MS in hospitalized patients (OR: 2.372, 95% CI: 1.282 to 4.387, p < 0.001) after adjusting for potential confounders. The area under the curve (AUC) value was 0.793 (95% CI: 0.736 to 0.851). The cut-off value for LLR was 3.18, with sensitivity and specificity values of 62.5% (95% CI: 53.2% to 71.2%) and 88.3% (95% CI: 81.2% to 93.5%), respectively. The EDSS scores of the higher LLR group were significantly higher than the lower group. CONCLUSION Systemic inflammation measured using LLRs may be an inflammatory marker among MS inpatients. LLRs may serve as favorable inflammatory markers with which to discriminate MS among Chinese subjects.

Abstract
Background Fingolimod is a sphingosine 1-phosphate receptor modulator approved for
relapsing MS. Long-term effects on the immunological profile are not fully
understood. Objective Investigate fingolimod's temporal effects on immune cell subsets, and safety
outcomes. Methods In FLUENT, a 12-month, prospective, non-randomized, open-label, phase IV
study, adult participants received fingolimod 0.5 mg/day. Changes in immune
cell subsets, anti-John Cunningham virus (JCV) antibody index, and serum
neurofilament levels were assessed. Results 165 fingolimod-naive and 217 participants treated for 2–12 years in routine
clinical practice were enrolled. Levels of all monitored peripheral
lymphocyte subsets were reduced from month 3 in fingolimod-naive
participants. Greatest reductions occurred in naive and central memory
CD4+ and CD8+ T cells, and in naive and memory B cells. Most lymphocyte
subset levels remained stable in the continuous fingolimod group. Components
of the innate immune system remained within reference ranges. No increase in
JCV seropositivity was observed. No single cellular subset correlated with
anti-JCV antibody index at any time point. Neurofilament levels remained
within healthy adult reference limits throughout. No opportunistic
infections were reported; no new or unexpected safety signals were
observed. Conclusion FLUENT provides insights into the utility of immunological profiling to
evaluate therapy response and potential infection risk.

Deng S, Lei Q, Lu W. Pregnancy-Related Attack in Neuromyelitis Optica Spectrum Disorder With AQP4-IgG: A Single-Center Study and Meta-Analysis. Front Immunol 2022; 12:800666. [PMID: 35069584 PMCID: PMC8767555 DOI: 10.3389/fimmu.2021.800666] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Accepted: 12/20/2021] [Indexed: 11/24/2022] Open
Abstract
Objective This study aimed to investigate the demographic characteristic of pregnancy-related attacks (PRAs) in neuromyelitis optica spectrum disorder (NMOSD). In addition, we investigated the predictors of PRAs as well as the effect of immunosuppressive (IS) therapy in patients with pregnancy-related NMOSD. Method We retrospectively analyzed data on clinical and diagnostic characteristics, therapeutic management, and pregnancy outcomes for PRAs in AQP4-IgG-positive NMOSD patients admitted to the Second Xiangya Hospital of Central South University. Moreover, we searched the literature (without any temporal restriction) to identify all such similar cohorts and performed a meta-analysis to evaluate the effectiveness and safety of IS therapy on NMOSD patients with PRAs. Result We collected clinical data on 117 women with AQP4 antibody-positive NMOSD; we ultimately included 33 patients (34 pregnancies). Ten patients were relapse-free during pregnancy, and 23 (69.7%) had PRA; attacks were most common during the first trimester of the postpartum period. Maintenance of IS treatment during pregnancy was found to greatly reduce PRAs in patients with NMOSD. PRAs were associated with a higher neutrophil-to-lymphocyte ratio (NLR) at relapse during pregnancy and shorter time interval between the last relapse and conception. The meta-analysis suggested that maintenance of IS treatment during pregnancy can significantly reduce the RR of NMOSD (95%CI=0.35-0.62; z=5.18, p<0.0001) and had no adverse effect on the miscarriage rate. However, the unhealthy newborn occurrence among those receiving IS treatment was 3.73 times higher than that of those not receiving treatment during pregnancy (95%CI=1.40–9.91; z=2.64, p=0.008). Conclusion Our study results demonstrates that pregnancy can induce the onset or relapse of attacks in NMOSD patients. The increased NLR value and disease activity may be a predictor for PRAs in patients with NMOSD. Moreover, administration of IS treatment during pregnancy can reduce the relapse rate. However, the dosage of drugs and risks of adverse effects to the fetus need to be considered. Future prospective studies with larger sample sizes are needed to confirm and extend our findings.
