Erythrocyte Sedimentation Rate Levels Research Articles

Development of clinical and laboratory biomarkers in an international cohort of 428 children with lupus nephritis.

Lupus nephritis (LN) is a very severe manifestation of lupus. There is no consensus on which treatment goals should be achieved to protect kidney function in children with LN. We retrospectively analyzed trends of commonly used laboratory biomarkers of 428 patients (≤ 18years old) with biopsy-proven LN class ≥ III. We compared data of patients who developed stable kidney remission from 6 to 24months with those who did not. Twenty-five percent of patients maintained kidney stable remission while 75% did not. More patients with stable kidney remission showed normal hemoglobin and erythrocyte sedimentation rate from 6 to 24months compared to the group without stable kidney remission. eGFR ≥ 90ml/min/1.73m2 at onset predicted the development of stable kidney remission (93.8%) compared to 64.7% in those without stable remission (P < 0.00001). At diagnosis, 5.9% and 20.2% of the patients showed no proteinuria in the group with and without stable kidney remission, respectively (P = 0.0001). dsDNA antibodies decreased from onset of treatment mainly during the first 3months in all groups, but more than 50% of all patients in both groups never normalized after 6months. Complement C3 and C4 increased mainly in the first 3months in all patients without any significant difference. Normal eGFR and the absence of proteinuria at onset were predictors of stable kidney remission. Significantly more children showed normal levels of Hb and erythrocyte sedimentation rate (ESR) from 6 to 24months in the group with stable kidney remission.

Hematological and plasma profiles and ticks and tick-borne pathogens in wild Formosan black bears (Ursus thibetanus formosanus)

BackgroundThe endangered Formosan black bear (Ursus thibetanus formosanus) is the largest native carnivorous mammal in Taiwan. Diseases, poor management, illegal hunting, and habitat destruction are serious threats to the survival of bear populations. However, studies on the impact of diseases on bear populations are limited. Therefore, this study aimed to establish a database of the hematological and plasma profiles of free-ranging Formosan black bears and investigate the occurrence of ectoparasites, blood parasites, and vector-borne pathogens.MethodsFormosan black bears were captured in Yushan National Park (YNP) and Daxueshan Forest Recreation Area (DSY) in Taiwan. Blood samples were collected from each bear for hematological analysis and plasma biochemistry using a hematology analyzer. Parasites and pathogens were detected using a thin blood smear with Wright–Giemsa staining and polymerase chain reaction (PCR) assay. Additionally, macroscopic ectoparasites were collected from bears to detect blood parasites and other pathogens. Moreover, the relationships between the bear variables (sex, age, and occurrence of parasites or pathogens), ectoparasites, and infectious agents were also analyzed.ResultsIn all, 21 wild bears (14 in YNP and 7 in DSY) were captured and released during the satellite tracking studies. Hematological analysis and plasma biochemistry indicated significant differences in white blood cells (WBC), segments, creatine kinase (CK), and lactate dehydrogenase (LDH) levels between foot snare and culvert-captured bears. Additionally, there were significant differences in total plasma protein (TPP), creatinine, Ca2+, Mg2+, and K+ levels between male and female bears. Moreover, pathogen-infected bears had significantly higher erythrocyte sedimentation rate (ESR; 30 min and 1 h) and globulin levels than uninfected bears. In total, 240 ticks were collected from 13 bears, among which eight adult tick species were identified, including Haemaphysalis flava, Haemaphysalis hystricis, Amblyomma testudinarium, Ixodes ovatus, Dermacentor taiwanensis, Haemaphysalis longicornis, Ixodes acutitarsus, Amblyomma javanense, and nymphs belonging to Haemaphysalis spp. PCR revealed that 13 (61.90%) and 8 (38.10%) bears harbored Hepatozoon ursi and Babesia DNA, respectively. Among the ticks examined, 157 (65.41%) and 128 (53.33%) samples were positive for H. ursi and Babesia, respectively.ConclusionsTo the best of our knowledge, this is the first study to establish a database of the hematological and plasma profiles of wild Formosan black bears and investigate ectoparasite infestation and Hepatozoon and Babesia spp. infection. In conclusion, these findings may serve as a reference for monitoring the health and population of locally endangered bears.Graphical

Predictive Significance of Laboratory Tests in Bacteremic Brucellosis.

Brucellosis is one of the most common zoonotic infections. Although culture is the gold standard diagnostic method, bacterial growth in blood cultures may not always occur due to various factors. We aimed to investigate demographic, clinical, and laboratory findings that may have predictive significance for bacteremia in brucellosis. Patients older than 18 years of age followed up with a diagnosis of brucellosis between 2012 and 2022 were included in this retrospective multicenter study. They were divided into two main subgroups according to their Brucella species reproductive status as bacteremic and non-bacteremic. A total of 743 patients, 370 (49.80%) bacteremic and 373 (50.20%) non-bacteremic brucellosis patients, were enrolled. The mean age of the bacteremic group (36.74 years) was lower than the non-bacteremic group (43.18 yr). High fever, chills/cold, sweating, nausea, vomiting, and weight loss were more common in the bacteremic group. In the bacteremic group, white blood cell count, platelet count, hemoglobin level, mean platelet volume, eosinophil, and neutrophil counts were lower, and lymphocyte, erythrocyte sedimentation rate, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and ferritin levels were higher. According to the receiver operating characteristic (ROC) analysis, when the cut-off value of ferritin was considered 67, it was the parameter with the strongest predictive significance in Brucella bacteremia. High ferritin level, low eosinophil count, and increased erythrocyte sedimentation rate were determined as the most critical laboratory findings in predicting bacteremia in brucellosis.

Guideline-Optimised Treatment in Heart Failure-Do Higher Doses Reduce Systemic Inflammation More Significantly?

Background: Chronic inflammation is a constant phenomenon which accompanies the heart failure pathophysiology. In all phenotypes of heart failure, irrespective of the ejection fraction, there is a permanent low-grade activation and synthesis of proinflammatory cytokines. Many classes of anti-remodelling medication used in the treatment of chronic heart failure have been postulated to have an anti-inflammatory effect. Methods: This retrospective study enrolled 220 patients and focused on evaluating the effect of the most used active substances from these classes in reducing the level of inflammatory biomarkers (C reactive protein, erythrocyte sedimentation rate and fibrinogen) after initiation or up-titration. Our research is evaluating if this anti-inflammatory effect intensifies while raising the dose. The evaluation was performed at two visits with an interval between them of 6 months. Results: From the beta-blockers class, carvedilol showed a reduction in erythrocyte sedimentation rate (ESR), in low (6.25 mg, bi daily) and medium (12.5 mg, bi daily) doses. At the same time, sacubitril/valsartan showed a reduction in CRP levels. This effect was obtained only in the medium (49/51 mg, bi daily) and high (97/103 mg, bi daily) doses, with the maximum reduction being observed in the high dose. Conclusions: From the classes of medication evaluated, the study showed a significant reduction in ESR levels in the low and medium doses of carvedilol and a reduction in CRP values in the cases of medium and high doses of ARNI.

#2684 Free light chains levels in ANCA associated vasculitis: a new potential inflammatory biomarker

Abstract Background and Aims Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a systemic disease characterized by an immune-mediated process where inflammation plays a central role. The widely available serum biomarkers of inflammation are not always able to detect ongoing disease activity in ANCA-associated vasculitis (AAV) patients. Free light chains (FLCs) expression levels have been proposed as new promising biomarker in some immune-mediated and inflammatory diseases. The aim of this study is to evaluate the expression levels of FLCs in patients affected by AAV and investigate the potential effect of rituximab treatment on FLCs levels. Method We conducted a retrospective multicenter study enrolling AAV patients in complete remission of AAV (defined as BVAS/GPA = 0); those with clinical suspicion of underlying hematologic malignancy were excluded. We analyzed κ and λ FLCs serum concentrations and evaluated their correlation with biomarkers of immune system activation, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), serum immunoglobulin (Ig) levels, serum C3 and C4 complement and albumin levels (which has a negative correlation with acute inflammatory phase). We assessed impact of rituximab (RTX) therapy within the last 6 months on the same laboratory parameters. Results A total of 137 patients with AAV were recruited, who were gender balanced, had an average age of 68 years and an estimated glomerular filtration rate of 68 (43-89) mL/min/1.73 m2. Fifty-one patients received rituximab treatment (RTX group), while 86 patients were on other immunosuppressive maintenance therapies (non-RTX group). In comparison to non-RTX group, patients treated with RTX experienced higher complement C3 levels, lower ESR levels and lower FLCs κ (p = 0.063) and λ (p = 0.013) levels. The differences between RTX and non-RTX groups in terms of FLCs were even more prominent after correction to total Ig concentration (p = 0.004 for κ /Ig and p = 0.003 for λ /Ig, respectively). Both, serum free κ and λ levels were found to correlate significantly with ESR (R = 0.55 and p &amp;lt; 0.001 for κ; R = 0.53 and p &amp;lt; 0.001 for λ) and albumin (R = ‒0.38 and p &amp;lt; 0.001 for κ; R = ‒0.33 and p &amp;lt; 0.001 for λ). Additionally, serum free κ levels showed an inverse association with C3 (R = ‒0.18 and p = 0.041). Conclusion In subjects with AAV, FLC levels were found to be associated with markers of inflammation and complement activation; hence FLCs levels may represent a promising biomarker for detection of subclinical inflammation in AAV patients on maintenance therapy. Rituximab therapy showed a potential to reduce the levels of markers of subclinical inflammation, including FLCs.

Platelet-to-lymphocyte ratio as a biomarker of systemic inflammation in systemic lupus erythematosus: A meta-analysis and systematic review.

The objective of this study was to evaluate the relationship between the platelet-to-lymphocyte ratio (PLR) and systemic lupus erythematosus (SLE). Additionally, the study aimed to establish an association between PLR and SLE disease activity, specifically lupus nephritis (LN). We conducted a comprehensive search across Medline, Embase, and Cochrane databases to identify relevant articles. Subsequently, we performed meta-analyses to compare PLR between SLE patients and controls, as well as active and inactive SLE cases, along with LN and non-LN groups. Furthermore, a meta-analysis was conducted on correlation coefficients between PLR and various parameters in SLE patients, including the SLE Disease Activity Index (SLEDAI), C3, C4, anti-dsDNA, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). In total, fifteen studies comprising 1,522 SLE patients and 1,424 controls were eligible for inclusion. The meta-analysis demonstrated a significant elevation of PLR in the SLE group compared to the control group (Standardized Mean Difference [SMD] = 0.604, 95% Confidence Interval [CI] = 0.299-0.909, p < 0.001). Upon stratification by ethnicity, an elevated PLR was observed in the SLE group among both Asian and Arab populations. Subgroup analysis based on sample size revealed consistently higher PLR in both small (n < 200) and large sample (n ≥ 200) SLE groups. Moreover, when considering disease activity, there was a noteworthy trend of increased PLR in the active disease group compared to the inactive group (SMD = 0.553, 95% CI = 0.000-1.106, p = 0.050). However, the meta-analysis did not demonstrate a significant distinction in PLR between the LN and non-LN groups. Notably, a positive association was established between PLR and SLEDAI (correlation coefficient = 0.325, 95% CI = 0.176-0.459, p < 0.001). Furthermore, PLR exhibited positive correlations with ESR, CRP, proteinuria, C3, and anti-dsDNA antibody levels. The outcomes of this meta-analysis underscored the elevated PLR in SLE patients, suggesting its potential as a biomarker for gauging systemic inflammation in SLE. Additionally, PLR exhibited correlations with SLEDAI, as well as with key indicators such as ESR, CRP, proteinuria, C3, and anti-dsDNA antibody levels.

Validating Joint Acoustic Emissions Models as a Generalizable Predictor of Joint Health.

Joint acoustic emissions (JAEs) have been used as a non-invasive sensing modality of joint health for different conditions such as acute injuries, osteoarthritis (OA), and rheumatoid arthritis (RA). Recent hardware improvements for sensing JAEs have made at-home sensing to supplement clinical visits a possibility. To complement these advances, models must be improved for JAEs to function as generalizable predictors of joint health. Addressing this need, this work investigates the effects of recording setup, location-specific factors, and participant population on previously validated JAE models. The effect of recording setup is first investigated by testing a model developed previously for a wearable brace to predict erythrocyte sedimentation rate (ESR) in participants with RA on benchtop data, resulting in an area under the receiver-operating characteristic curve (AUC), sensitivity, and specificity of 0.79, 0.73, and 0.81 respectively. Investigating the effects of participant population type and location-specific factors, a feature-based model and a convolutional neural network (CNN) were both trained with healthy and RA data to predict ESR level, and then tested on a new dataset containing healthy, pre-radiographic osteoarthritis (Pre-OA), and OA data. The feature-based model had an AUC of 0.69 and 0.94, a sensitivity of 0.38 and 0.80, and a sensitivity of 1, while the CNN had an AUC of 0.85 and 0.99, a sensitivity of 0.50 and 1, and a specificity of 0.90 for detecting Pre-OA and OA respectively. The ability to generalize models across setup, location, and participant population provides a foundation for using JAEs as a measure of joint health.

Identifying the Probable Etiology of Acute Undifferentiated Fever through Inflammatory Markers.

Acute undifferentiated fever (AUF) is defined as any febrile illness with a duration of ≤14 days without evidence of localized infection. Most outpatient services and a significant inpatient load in India are contributed by AUF. COVID-19 has recently added to the existing list of common etiologies of AUF. While the rapid diagnostic test (RDT) kits, which are widely used for the detection of common etiologies of AUF, are unreliable, the rise of various inflammatory markers may help identify the probable etiology. This not only results in better diagnosis but also prepares the physician for close monitoring and pooling of resources. To identify the probable etiology of AUF through inflammatory markers. To understand the clinical and biochemical parameters as possible predictors of adverse outcomes in AUF. This was a prospective observational study carried out in the Department of Medicine in a tertiary care hospital. The total duration of the study was 1 year. A total of 400 AUF patients [both outpatient department (OPD) and inpatient department (IPD)] fulfilling the eligibility criteria were taken up for the study after consent. Various inflammatory markers, namely erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), D-dimer, ferritin, and procalcitonin levels along with basic blood and biochemical tests were measured in all qualifying patients at their first visit. The level of rise of all the measured inflammatory markers was analyzed for clues toward identifying the etiology. Also, the possible predictors of adverse outcomes, as defined in the study, were analyzed. Outcome variables are described as mean ± standard deviation. All statistical calculations were done using computer programs Microsoft Excel 2007 (Microsoft Corporation, New York, United States of America) and SPSS (Statistical Product and Service Solutions; SPSS Inc., United States of America) version 21. The common etiologies in our study contributing to AUF were dengue (31.5%), COVID-19 (18.5%), enteric fever (12.7%), scrub typhus (9.0%), and malaria (6.0%). In 76 cases (19%), the fever was undiagnosed. Enteric fever had highly elevated CRP (>30 mg/L) and moderately elevated D-dimer, ferritin, and procalcitonin. Both nonsevere dengue and COVID-19 had highly elevated D-dimer (>750 ng/mL), but in nonsevere dengue, CRP, ferritin, and procalcitonin were only mildly elevated, whereas in COVID-19, CRP and ferritin were moderately elevated with mildly elevated procalcitonin. Scrub typhus had highly elevated CRP and ferritin [more than four times the upper limit of normal (ULN)], but D-dimer and procalcitonin were only mildly elevated. The mean serum procalcitonin level in enteric fever is significantly higher than the other etiologies of AUF. Our study was correctly able to identify 90.8% of nonsevere dengue, 87.8% of typhoid, 83.6% of COVID-19, and 91.4% of scrub typhus patients based on the inflammatory markers level. Obesity, diabetes (both types 1 and 2), hypertension, coronary artery disease (CAD), malignancy, chronic kidney disease (CKD), and chronic lung disease were significantly associated with adverse outcomes. A significant delay in visiting the hospital after the onset of fever was found in all etiologies of AUF, which had adverse outcomes. Our study is one of the few studies comparing the rise in the level of various inflammatory markers among the common etiologies of AUF. The novelty of the study is that it aids in identifying the probable etiology of AUF with good confidence through the levels of inflammatory markers. Also, our study highlights the high-risk factors associated with adverse outcomes in AUF.

A Comprehensive Analysis of Renal and Endothelium Dysfunction Markers Fourteen Years after Hemorrhagic Fever with Renal Syndrome Contraction.

While the pathology of acute hemorrhagic fever with renal syndrome (HFRS) has been widely researched, details on the chronic HFRS sequelae remain mainly unexplored. In this study, we analyzed the clinical and laboratory characteristics of 30 convalescent HFRS patients 14 years after the disease contraction, mainly emphasizing several endothelial dysfunction parameters. Convalescent HFRS patients exhibited significantly higher serum levels of erythrocyte sedimentation rate, von Willebrand factor, uric acid, C-reactive protein and immunoglobulin A when compared to healthy individuals. Furthermore, 24 h urine analyses revealed significantly lower sodium and potassium urine levels, as well as significantly higher proteinuria, microalbumin levels and β2-microglobulin levels when compared to healthy individuals. First morning urine analysis revealed significantly higher levels of hematuria in convalescent HFRS patients. None of the additional analyzed endothelium dysfunction markers were significantly different in post-HFRS patients and healthy individuals, including serum and urine P-selectin, E-selectin, soluble intercellular adhesion molecule 1, vascular intercellular adhesion molecule 1 (sVCAM-1) and vascular endothelial growth factor (VEGF). However, binary logistic regression revealed a weak association of serum sVCAM-1 and urine VEGF levels with HFRS contraction. Generally, our findings suggest mild chronic inflammation and renal dysfunction levels in convalescent HFRS patients 14 years after the disease contraction.

Association of using enteral nutrition containing probiotics and dietary inflammatory index with inflammatory factors serum levels and gastrointestinal complications in infected patients with COVID-19

PurposeThis paper aims to examine the association between the dietary inflammatory index, the consumption of Enteral Nutrition Supplemented with probiotics with certain serum inflammation markers and gastrointestinal complications among individuals diagnosed with COVID-19.Design/methodology/approachThis cross-sectional investigation involved 100 COVID-19 patients who were admitted to intensive care units in hospitals. These patients were administered two different types of Enteral Nutrition, so the dietary inflammatory index (DII), gastrointestinal complications and some serum inflammation markers have been compared between two groups.FindingsThe mean DII scores in all patients were significantly pro-inflammatory (probiotic formula 2.81 ± 0.01 vs usual formula group 2.93 ± 0.14 p = 0.19). The probiotic formula consumption had an inverse association with High-sensitivity C-reactive Protein concentration (coef = −3.19, 95% CI −1.25, −5.14 p = 0.001) and lead to a reduction of 2.14 mm/h in the serum level of Erythrocyte sedimentation rate compared to normal formula. The incidence of diarrhea, abdominal pain and vomiting in probiotic formula patients was respectively 94%, 14% and 86% less than in usual formula patients (p = 0.05).Originality/valueIn this cross-sectional study for the first time, the authors found that probiotic formula consumption was inversely associated with serum inflammation markers and gastrointestinal complications incidence. The high DII leads to more gastrointestinal complications incidence and inflammation markers. More studies are needed to prove this relationship.

Assessment of visual and blood-related parameters among children with sickle cell anaemia at Murtala Muhammad Specialist Hospital in Kano, Nigeria.

Sickle cell disease (SCD) is a prevalent genetic disease worldwide and particularly in Nigeria. Retinopathy is a known complication of SCD, underscoring the need to assess visual parameters in children. This study aimed to evaluate the visual acuity (VA), color vision (CV), packed cell volume (PCV), and erythrocyte sedimentation rate (ESR) of Sickle cell anemic (SCA) patients attending the Sickle cell counseling unit of Murtala Muhammad Specialist Hospital (MMSH) in Kano. It was a descriptive cross-sectional study consisting of 60 participants, including 30 SCA patients and 30 healthy controls without systemic or ocular diseases, aged between 8 and 14 years. Visual acuity, CV, PCV, and ESR were assessed using Snellen Chart, Ishihara chart, Hematocrit test, and Westergren Method respectively. Data were analyzed using SPSS version 22.0. Statistical significance was set at P &lt; 0.05. Both SCA patients and controls demonstrated limited knowledge about VA, CV, and ESR tests, and a significant percentage had never undergone these tests. SCA patients exhibited mild to moderate visual impairment (VI) in both eyes, while controls had no VI. Abnormally low PCV and ESR values were observed in all SCA patients, whereas controls had normal values. Gender differences were observed in ESR levels, with females showing higher levels. Significant differences were found between controls and SCA patients in terms of VA, ESR, and PCV values. There was a general lack of awareness regarding the importance of VA and CV tests in the community. Visual impairment and abnormal PCV and ESR values were exclusive to the SCA patients, indicating their association with the disease.

Immunological alterations in patients with current and lifetime suicide ideation and attempts: Examining the relationship with depressive symptoms

BackgroundSuicidal ideation and attempt (SI/SA) have been associated with dysregulation of the immune response and inflammation. However, few studies have explored how innate and acquired cellular immunity impact on the peripheral immune response. Our study addresses this gap by examining the composition of peripheral immune cells and humoral markers among individuals with current SI/SA, individuals with a history of SI/SA, and healthy controls (HC). Additionally, we aim to explore whether depressive symptoms settle the relationship between inflammation and SI/SA. MethodsThis is a multicenter case-control study that included 105 participants. Clinical and demographic characterists together with hemogram parameters, soluble pro and anti-inflamatory factors, and specific innate and adaptive immune cell populations were compared among patients with current SI/SA (n = 21), a history of lifetime SI/SA (n = 42), and HC (n = 42). ResultsPatients with both current and lifetime SI/SA had a significant increase in the absolute count of monocytes and in the monocyte/lymphocyte ratio (MLR). Additionally, patients with current and lifetime SI/SA showed a significant increase in high-sensitivity C- reactive protein (hs-CRP), and patients with lifetime SI/SA also showed higher levels of Erythrocyte Sedimentation Rate (ESR). The cellular inflammatory status of patients with SI/SA was characterized by altered proportions of monocytes with higher levels of nonclassical and intermediate monocytes. No differences were observed in the number of lymphocytes and the proportion of CD4 and CD8 between patients and HC, but we found differences in markers of exhaustion of CD4 lymphocytes, with increased levels of Programmed cell death protein 1 (PD1) in Current SI/SA and Lymphocyte activation gene 3 (LAG3) in Current SI/SA and Lifetime SI/SA compared to HC. The plasmainflammatory status was marked by higher levels of soluble Triggering receptor expressed on myeloid cells 2 (sTREM2) in patients with lifetime SI/SA compared to HC. Finally, the multinomial analysis indicates that inflammation and depressive symptoms are independently associated with SI/SA. ConclusionThis study highlights the association of immunological alterations with SI/SA. Furthremore, SI/SA is independently influenced by depressive symptoms and inflammation. This may have important therapeutic implications, as in these patients, it may be necessary to treat the inflammatory process beyond treating the depressive symptoms.

E039 Multiple myeloma and neurological complications: prevalence and risk factors

Abstract Background/Aims Multiple myeloma (MM) is a malignant haematological disorder with a highly variable clinical presentation. Few studies have explored the neurological complications (CN) associated with MM. The objectives of this study were to describe the neurological manifestations observed in MM and to determine predictive factors for neurological complications. Methods We collected data from 126 cases of symptomatic multiple myeloma patients followed in our department over a 30-year period (1993 - 2023). We gathered sociodemographic, clinical, and laboratory data. Neurological complications were diagnosed based on clinical findings and magnetic resonance imaging data. Results Our study included 126 patients with an average age of 65.23 ± 11.63 years [36-92], and a male-to-female sex ratio of 3.8. Bone pain was present in 92.1% (116 cases) with an average duration of 4 months. The mean erythrocyte sedimentation rate and C-reactive protein levels were 99.08 mm at H1 [3-190] and 27.74 [0-196], respectively. Hemoglobin levels were less than 10g/dl in 51.2% of cases, with an average of 9.902 ± 2.22 g/dl [5-13.9]. Calcium levels exceeded 2.75 mmol/l in 20% of cases, with an average of 2.49 ± 0.33 mmol/l. The mean creatinine level was 88.28 ± 77.9 μmol/l [36-587], with levels above 177 μmol/l observed in 15 cases (10.4%). The Durie and Salmon prognostic classification categorized our patients as follows: Stage IA (3.2%), Stage IIA (4%), Stage IIB (0.8%), Stage IIIA (72.2%), and Stage IIIB (18.3%). Neurological complications were present in 22.2% of patients (n = 28). Sixteen patients (12.7%) had spinal cord compression, with nine having dorsal involvement, six having conus medullaris involvement, and one having cervical involvement. Radicular pain affected 14 patients, with eight experiencing sciatalgia and four having cruralgia. Two patients (1.8%) had carpal tunnel syndrome. No cerebral involvement was observed in our series. In our study, only creatinine levels were significantly lower in patients who developed neurological complications (64.35 vs. 95.19, p = 0.004). However, the occurrence of neurological complications was independent of age (p = 0.696), duration of evolution (p = 0.669), erythrocyte sedimentation rate (p = 0.541), C-reactive protein (p = 0.963), hemoglobin (p = 0.076), or calcium levels (p = 0.274). No association was found between neurological complications and gender (p = 0.849) or prognostic stage (p = 0.119) Conclusion Neurological manifestations in MM are diverse and often underestimated. The diagnosis of MM should be considered in the presence of spinal or radicular compression, especially when the laboratory findings suggest it. Disclosure M. Dhifallah: None. I. Fenniche: None. A.

Association of gene polymorphisms and the decreased expression of long non-coding RNA LOC553103 with rheumatoid arthritis.

Long non-coding RNAs (lncRNAs) are involved in many key bioprocesses, including the occurrence and development of rheumatoid arthritis (RA). We aimed to analyze the association of genetic variants of long non-coding RNA LOC553103 and its peripheral blood mononuclear cells (PBMC) expression with RA. We enrolled 457 RA patients and 551 healthy controls and conducted a case-control study to analyze the relationship between LOC553103 gene rs272879 and the susceptibility of RA by TaqMan single nucleotide polymorphism genotyping. Among them, we sampled 92 cases and 92 controls, respectively, to detect the PBMC level of LOC553103 using quantitative real-time polymerase chain reaction technology. We explored the association between LOC553103 rs272879 and its PBMC expression levels in 71 RA patients. Mann-Whitney, Chi-square, and Spearman correlation analysis were used for statistical analysis and P-value <.05 was considered statistically significant. The genotype frequency of LOC553103 rs272879 CC was increased, and CG was decreased in RA patients compared to the control group (χ2 = 6.772, P = .034). The LOC553103 expression level in PBMC of RA patients was downregulated compared to healthy control (Z = -4.497, P < .001). Moreover, negative correlations were observed between the PBMC level of LOC553103 and erythrocyte sedimentation rate (rs = -0.262, P = .018), white blood cell count (rs = -0.382, P = .004), platelet (rs = -0.293, P = .030), and disease activity score in 28 joints (rs = -0.271, P = .016) in RA patients. This study provides the first evidence supporting an association between LOC553103 gene polymorphisms and susceptibility of RA and a relationship of PBMC level of LOC553103 with clinical manifestations and laboratory indicators of RA patients.

Impact of elevated body mass index (BMI) on cognitive functioning and inflammation in persons with post-COVID-19 condition: a secondary analysis.

Individuals who have recovered from the acute stage of SARS-CoV-2 infection may be at risk of developing post-COVID-19 condition (PCC), characterised by a spectrum of persisting, non-specific, and functionally impairing symptoms across multiple organ systems. Obesity has been implicated as a risk factor for PCC, mediated by chronic systemic inflammation. The foregoing has also been separately reported to mediate cognitive dysfunction in PCC. This is a post-hoc analysis of a randomised, double-blinded, placebo-controlled clinical trial evaluating vortioxetine treatment for cognitive impairments in persons with PCC who received vortioxetine or placebo for eight weeks. This analysis comprises baseline data, examining the impact of BMI on cognitive functioning measured by the Digit Symbol Substitution Test (DSST) and Trails Making Tests (TMT)-A/B, as well as inflammation, via serum c-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Complete data from 70 participants were statistically analysed and adjusted for age and sex. BMI was negatively correlated with performance on the DSST (β = -0.003, p = 0.047), TMT-A (β = -0.006, p = 0.025), and TMT-B (β = -0.006, p = 0.002). BMI was positively correlated with serum CRP (unstandardized β = 0.193, standardized β = 0.612, p < 0.001) and ESR (β = 0.039, p < 0.001) levels. We observed a significant negative correlation between BMI and cognitive functioning, and a significant positive correlation between BMI and inflammation in persons with PCC, suggesting a bidirectional interplay between BMI, PCC, and cognitive function; individuals with an elevated BMI may be at a greater risk of developing PCC and/or presenting with greater cognitive deficits mediated by chronic systemic inflammation.

MARKERS OF COMPLICATIONS AFTER LAPAROSCOPIC GASTRIC BYPASS IN PATIENTS WITH OBESITY

Introduction. Bariatric surgery is one of the most effective methods of treating morbid obesity, which allows for a long-lasting result. Along with the increase in the number of operative methods of obesity treatment, the relevance of issues related to postoperative complications is increasing. In recent years, the issue of using special checklists after surgery has been actively investigated. This will help optimize the process of monitoring patients' condition in the postoperative period.&#x0D; The aim of the study: to develop a check-list model to prevent the detection of complications after laparoscopic gastric bypass in obese patients.&#x0D; Materials and methods. On the basis of the developed checklist, a study of the condition of obese patients, who underwent laparoscopic gastric bypass during 2019-2023, was conducted on the basis of the Department of General Surgery No. 2 of the Bogomolets National Medical University. The checklist included the following criteria: the level of pain on the VAS scale, the level of nausea, eating, mobility, whether there is a desire to be discharged home, abdominal muscle tension, pain in the calf muscles, heart rate, oxygen saturation in the blood, the number drainage discharge within 24 hours, temperature, systolic blood pressure, central venous pressure, laboratory diagnosis, decrease in hemoglobin concentration, leukocyte level after surgery, C-reactive protein level after surgery, blood procalcitonin level, erythrocyte sedimentation rate level, the presence of a shift in the leukocyte formula to the left. The presence of complications was assessed, the parameters of the checklist were analyzed using univariate logistic regression and ROC analysis for early detection of complications and determination of the chance of complications in the future.&#x0D; Results. Complications occurred in 18/218 (8.2%). The most frequent complication was bleeding in 6/18 (33.3%). Reoperation was performed in 12 cases of 12/18 (66.6%), endoscopic treatment was performed in 1 case, and conservative methods were used in 5 cases. According to the checklist, 31.81% had a positive predictive value (PPV) and 99.56% had a negative predictive value (NPV). The optimal cut-off point of the total score of the checklist was 6. Patients with a positive prognosis of the checklist have a higher chance of developing complications of VSH – 4.5 (95% CI 1.8-9.72), p &lt;0.001.&#x0D; Conclusions. The complication rate was 18/218 (8.2%). According to the checklist, heart rate, systolic blood pressure and mobility are very good predictors of postoperative complications. The checklist is the best option for determining the readiness of patients to be discharged from the hospital due to a high prognostic negative result. Due to the low prognostic positive result, the evaluated checklist needs additional modification and optimization taking into account the results already obtained.

Serum PYCARD may become a new diagnostic marker for rheumatoid arthritis patients

BackgroundThe objective of this investigation is to analyze the levels and clinical relevance of serum PYCARD (Pyrin and CARD domain-containing protein, commonly known as ASC—apoptosis-associated speck-like protein containing a caspase activation and recruitment domain), interleukin-38 (IL-38), and interleukin-6 (IL-6) in individuals afflicted with rheumatoid arthritis (RA).MethodsOur study comprised 88 individuals diagnosed with RA who sought medical attention at the Affiliated Hospital of Chengde Medical University during the period spanning November 2021 to June 2023, constituting the test group. Additionally, a control group of 88 individuals who underwent health assessments at the same hospital during the aforementioned timeframe was included for comparative purposes. The study involved the assessment of IL-38, IL-6, PYCARD, anti-cyclic citrullinated peptide antibody (anti-CCP), and erythrocyte sedimentation rate (ESR) levels in both groups. The research aimed to explore the correlations and diagnostic efficacy of these markers, employing pertinent statistical analyses for comprehensive evaluation.ResultsThe test group had higher expression levels of PYCARD, IL-6, and IL-38 than the control group (P < 0.05). Based on the correlation analysis, there was a strong relationship between PYCARD and IL-38 (P < 0.01). The receiver operating characteristic (ROC) curve analysis revealed area under the curve (AUC) values of 0.97, 0.96, and 0.96 when using combinations of PYCARD and anti-CCP, IL-38 and anti-CCP, and IL-6 and anti-CCP for predicting RA, respectively. Importantly, all three of these pairs demonstrated superior AUC values compared to PYCARD, IL-38, IL-6, ESR, or anti-CCP used as standalone diagnostic indicators.ConclusionPYCARD, IL-6, and IL-38 exhibit promising potential as novel diagnostic markers and may constitute valuable tools for supporting the diagnosis of RA.

Role of endoplasmic reticulum aminopeptidase-1 gene polymorphism (rs13167972) in occurrence susceptibility of ankylosing spondylitis in a sample of Iraqi male patients.

Ankylosing spondylitis (AS) is a chronic and systemic seronegative inflammatory spondyloarthropathy, an autoimmune disease that has been associated with impaired Endoplasmic Reticulum Aminopeptidase (ERAP)-1 activity, which is involved in priming antigenic peptides. The purpose of this study is to investigate the association of 3-UTR of ERAP1 gene polymorphism (rs13167972) with the AS occurrence susceptibility in a sample of Iraqi male patients. The AS patients were diagnosed clinically and by magnetic resonance imaging (MRI) and other clinical and laboratory criteria like symptoms, increased C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). The blood grouping and Body Mass Index (BMI) were also investigated to be associated with AS occurrence. The genotyping of the 3-UTR region of the ERAP1 gene (rs13167972) was done by Sanger sequencing. The results revealed that the AS occurred significantly in the age group of 20-35years (p = 0.013). The BMI shows that the AS patients were overweighted males (p = 0.013) and the most predominant blood group in AS patients was O- (p = 0.002). The ESR and serum level of CRP were significantly raised in AS patient sera (< 0.001). The results of the receiver-operating characteristics curve analysis (ROC) revealed that the CRP (AUC: 0.995, cut-off: 2.48mg/L, had 95% %sensitivity, 100% specificity, p < 0.001) is more discriminative than BMI (AUC: 0.300, cut-off: 46.91kg, had 0% sensitivity, 100% specificity, p = 0.001), and ESR (AUC: 0.808, cut-off: 7.50mm/hr, had 60% sensitivity, 88% specificity, p < 0.001) in distinguishing between AS patients and control group. The genotyping of the 3-UTR region of ERAP1 gene (rs13167972) result shows that the AG and GG genotypes are significantly occurring in AS patients (70%, OR: 2.33, 95%CI: 1.02-5.36, p = 0.04). The G allele is significantly occurring in AS patients (47%, OR: 2.07, 95CI%: 1.15-3.71, p = 0.01). The AS occurred in young overweight males with blood group O-. The AG and GG genotypes are risk factors for AS development while the G allele is a risk factor that increases the chances for disease incidence.

Comparison of efficacy of acupuncture-related therapies in treating Acute Gouty Arthritis: A Network Meta-Analysis of Randomized Controlled Trials

Backgroundand purpose: Acupuncture and moxibustion, as a complementary and alternative therapy, has been widely used in the treatment of acute gouty arthritis (AGA). However, there are various forms of acupuncture and moxibustion, and the curative effect of different forms is different. This study evaluated the clinical efficacy of different acupuncture therapies in treating AGA by network meta-analysis. MethodsComputer searches of English databases (including PubMed, The Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Embase) and Chinese databases (including China National Knowledge Infrastructure (CNKI), VIP Database, Wanfang Database and China Biomedical Literature Database) were conducted for randomized controlled trials (RCTs) of acupuncture therapies in treating AGA. We set the search time from the database establishment to May 2022. Data analysis was performed using Stata14.2 software. ResultsThirty-two RCTs involving 2434 patients with AGA were screened out. The results showed that in terms of the improvement of pain visual analogue scale (VAS) scores, the top ones were acupoint application (100%), electroacupuncture + Western medicine (73.5%) and acupuncture + Western medicine (69.2%); In terms of total effective rate, acupoint application (85.2%), acupuncture (75.2%) and acupuncture + Western medicine (63%) ranked the top; In terms of reducing serum uric acid (SUA) levels, the top ones were acupoint application (95%), acupuncture + Western medicine (87.5%) and acupuncture (66.2%); In terms of the reduction of erythrocyte sedimentation rate (ESR), acupuncture (95%), acupoint application (84.7%), and electroacupuncture + Western medicine (52.8%) were the most prominent. ConclusionThe existing evidence shows that acupoint application has more advantages in improving the total effective rate, improving pain and reduce SUA levels, and acupuncture has an advantage in reducing ESR levels and adverse events. However, due to the low qualities of the original studies, the quality of this evidence is poor. Therefore, it is recommended that more scientific research be performed to confirm the efficacy of acupuncture.

The impact of inflammatory biomarkers on amputation rates in patients with diabetic foot ulcers.

Diabetic Foot Ulcers (DFUs) are a major complication of diabetes, often leading to amputation. Understanding the relationship between haematological inflammatory markers and the incidence of amputation in DFU patients with infectious complications is crucial for improving management and outcomes. This retrospective study, conducted from May 2020 to October 2022, involved 109 patients with DFUs, categorised into amputation (AM) and non-amputation (NAM) groups. Patients were evaluated for various factors, including demographic data, DFU duration, and blood parameters such as haemoglobin A1c (HbA1c), haemoglobin (Hb), albumin (ALB), white blood cell count (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C-reactive protein (CRP), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR). Statistical analyses were performed using independent sample t-tests, Mann-Whitney U test and logistic regression. The univariate analysis showed no significant difference in BMI, DM duration or DFU duration between groups. However, significant differences were noted in PCT, Hb, ESR, ALB, HbA1c and WBC levels, and in inflammatory ratios (NLR, PLR and LMR). Multivariate logistic regression identified CRP, NLR and PLR as independent risk factors for amputation. The study highlights CRP, PLR and NLR as key independent risk factors for amputation in patients with DFUs. These easily obtainable markers from routine blood tests can effectively aid in predicting the risk of osteomyelitis and amputation, enhancing clinical decision making and patient care strategies.
