Evaluation of functional measures and laboratory parameters to portend limitations of spinal mobility in patients with radiographic axial spondyloarthritis

Aim of the workTo specify clinical and laboratory parameters related to limited spinal mobility in radiographic axial spondyloarthritis (r-axSpA) patients. Patients and methodsThe study included 202 adult r-axSpA patients. Clinical characteristics, medications, investigations including serum C-reactive protein (CRP) and human leukocytic antigen-B27 positivity were noted. Lateral lumbar flexion (LLF), chest expansion (CE) and tragus-to-wall distance (TWD) were measured. Values <2.5 percentile in LLF, CE and TWD were noted as reduced mobility of lumbar, thoracic and cervical spine, respectively. ResultsThe median age of patients was 43 years, male:female was 3.7:1. The time to diagnosis was 7.5 (3–40) years and were followed-up for 7.2 (4–22) years. Disease duration and high baseline CRP (>10 mg/L) were critical risk factors for reduced spinal mobility (p = 0.001 and p < 0.01). The duration to impaired LLF was significantly shorter in smokers (n = 105) (10.3;0–30.5 years) vs non-smokers (15.2;4.5–35 years) (p = 0.001) and in those with positive family history (n = 50) (9.7;0–20 years) compared to those without (12.9;4–35 years) (p = 0.09). LLF, CE and TWD were impaired in 40 % vs 75 %, 10 % vs 55 % and 12 % vs 60 % of patients with symptom duration of 10 vs 30 years respectively. Those with delayed introduction of biologics had significantly more impaired LLF, CE and TWD: 10.1(2–25) vs 14(3–33) years; 10.4(3–26) vs 17.5(8–33) years; 10.7(3–27) vs 16.7(5–33) years; p = 0.001 for all, respectively). ConclusionsThe most prominent factors affecting spinal mobility were the duration of symptoms and high serum CRP levels. The decreased spinal mobility was markedly less in patients with the early introduction of biologic therapy.

Efficacy of Epidural Steroid in Controlling Pain After Unilateral Biportal Endoscopic Discectomy for Single-Level Lumbar Disc Herniation: A Randomized, Double-Blind, Placebo-Controlled Trial.

The effects of epidural steroid (ES) administration following open or minimally invasive surgery lumbar discectomy have been extensively studied. However, no research has investigated the impact of steroids following the unilateral biportal technique endoscopic lumbar discectomy (UBE-D) for lumbar disc herniation. This study aims to evaluate the efficacy of ES administration in controlling postoperative pain and disability scores following UBE-D for single-level lumbar disc herniation. This double-blind, randomized, placebo-controlled trial was conducted between June 2021 and June 2023. Eighty-two patients were assessed, and 60 were eligible and randomized to receive either ES (n = 30) or saline (placebo; n = 30) after UBE-D. The Outcome measures included visual analog scale scores for pain, Oswestry Disability Index scores, morphine consumption over 24 hours, serum C-reactive protein levels, and the occurrence of complications over a 6-month follow-up period. The baseline characteristics were comparable between the 2 groups, with no significant differences observed. Analysis of visual analog scale scores for back and leg pain, as well as Oswestry Disability Index scores, at various postoperative time points (6 hours, 12 hours, 24 hours, 2 weeks, 6 weeks, 3 months, and 6 months), showed no statistically significant differences between the ES and placebo groups (P values ranged from 0.47-0.94). Additionally, no significant differences were found in morphine consumption within the first 24 hours postoperatively (P = 0.85), length of hospital stay (P = 0.36), or C-reactive protein levels at 24 hours and 3 weeks postoperatively (P values ranged from 0.54-0.79) between the 2 groups. Importantly, no postoperative or steroid-related complications were reported in either group within the 6-month follow-up period. ES administration after UBE-D did not significantly reduce postoperative pain, disability scores, or morphine consumption compared with placebo. The findings suggest that routine use of ESs in this context may not provide additional benefits. Clinicians should reconsider the use of epidural steroids as part of standard postoperative management after UBE-D, as the lack of significant improvement in patient outcomes indicates that alternative pain management strategies may be more effective.

Fecal glycoprotein 2 is a marker of gut microbiota dysbiosis and systemic inflammation

BackgroundAntimicrobial autoantigenic glycoprotein 2 (GP2) is an important component of the innate immune system which originates from the exocrine pancreas as well as from the small intestines. The relationship of GP2 with the intestinal microbiome as well as the systemic implications of increased fecal GP2 levels are, however, still unclear. Therefore, fecal samples from 2,812 individuals of the Study of Health in Pomerania (SHIP) were collected to determine GP2 levels (enzyme-linked immunosorbent assay) and gut microbiota profiles (16 S rRNA gene sequencing). These data were correlated and associated with highly standardised and comprehensive phenotypic data of the study participants.ResultsFecal GP2 levels were increased in individuals with higher body mass index and smokers, whereas lower levels were found in case of preserved exocrine pancreatic function, female sex or a healthier diet. Moreover, higher GP2 levels were associated with increased serum levels of high-sensitivity C-reactive protein, loss of gut microbial diversity and an increase of potentially detrimental bacteria (Streptococcus, Haemophilus, Clostridium XIVa, or Collinsella). At the same time, predicted microbial pathways for the biosynthesis of beneficial short-chain fatty acids or lactic acid were depleted in individuals with high fecal GP2. Of note, GP2 exhibited a stronger association to overall microbiome variation than calprotectin.ConclusionFecal GP2 is a biomarker of gut microbiota dysbiosis and associated with increased systemic inflammation. The intestines may be more important as origin for GP2 than pancreatic acinar cells. Future studies need to investigate the potential clinical value in disease specific patient cohorts.

Comparative efficacy of unilateral biportal endoscopic and full-endoscopic posterior cervical foraminotomy in the treatment of cervical spondylotic radiculopathy: a retrospective analysis.

The aim of this study was to compare the clinical efficacy of the full-endoscopic posterior cervical foraminotomy (FE-PCF) and the unilateral biportal endoscopic posterior cervical foraminotomy (UBE-PCF) in the treatment of cervical spondylotic radiculopathy (CSR). Patients who underwent posterior cervical spine surgery in our hospital from January 2020 to December 2022 were retrospectively analyzed. According to the surgical method, the patients were divided into two groups: FE-PCF group and UBE-PCF group. Perioperative data included operation time, Intraoperative blood loss and postoperative hospital stay were collected. The Visual Analog Scale (VAS)-arm, VAS-neck, and Neck Diability Index (NDI) was used to evaluate the clinical outcomes at preoperative, postoperative 1 week and Last follow-up. Serum creatine phosphokinase (CPK) and C-reactive protein (CRP) levels were recorded to evaluate surgical invasiveness. A total of 160 patients were included, including 89 cases of FE-PCF and 71 cases of UBE-PCF. The demographic and preoperative data showed no significant differences between the two groups (P > 0.05). The mean operating time was significantly shorter in the UBE-PCF group compared to FE-PCF group (P < 0.05). Serum CRP and CPK levels of the two groups both exhibited a pattern of rising and then falling, peaking one day following surgery and decreasing to near normal values three days after the operation. Compared with preoperative, both groups showed significant improvement in postoperative VAS and NDI scores, with a statistically significant difference (P < 0.05). However, the differences in results between the groups were not significant. Both UBE-PCF and FE-PCF are secure and efficient methods for treating CSR by continuous visualization. UBE-PCF offers predictable and adequate decompression within a reduced surgical duration, facilitated by its separate observation and operation channels.

Extracorporeal Photopheresis with 5-Aminolevulinic Acid in Crohn's Disease-A First-in-Human Phase I/II Study.

Background/Objectives: With the increasing prevalence of Crohn's disease (CD), treatment options for patients who fail conventional and advanced therapy are highly needed. Therefore, we explored the safety and efficacy of extracorporeal photopheresis (ECP) using 5-aminolevulinic acid (ALA) and blue light (405 nm). Methods: Patients with active CD who failed or were intolerant to biological therapy were eligible. Mononuclear cells (90 mL) were collected from each patient using a Spectra Optia® apheresis system and diluted with 100 mL of 0.9% sodium chloride in a collection bag. The cells were incubated with ALA at a concentration of 3 millimolar (mM) for 60 min ex vivo and illumination with an LED blue light (405 nm) source (BLUE-PIT®) before reinfusion to the patient. Recording of vital signs and adverse events were regularly performed. At week 13, we assessed the patients with colonoscopy, the Harvey Bradshaw Index (HBI), the Inflammatory Bowel disease Health Related Quality of Life Questionnaire, and the measurement of serum C-reactive protein and fecal calprotectin (FC) levels. Biopsies of the intestines were taken for immunohistochemistry. Results: Seven patients were included. Four patients completed the treatments, with a total of 24 treatments. Three of the four patients achieved a favorable response, including a lower HBI, lower FC levels, and/or endoscopic improvement. No significant adverse events were observed. The remaining three patients received only one, three, or five treatments due to technical difficulties, medical reasons, or the withdrawal of informed consent. Conclusions: ALA-based ECP appears safe and seems to give some clinical improvement for the patients with active CD who failed to respond to conventional and advanced therapies.

Efficacy of multimodal analgesia based on the concept of enhanced recovery after surgery in laparoscopic radical gastrectomy for gastric cancer

Objective: To explore the effect of multimodal analgesia based on the concept of enhanced recovery after surgery (ERAS) in patients undergoing laparoscopic radical gastrectomy (LRG) for gastric cancer (GC). Methods: Clinical data of 128 patients undergoing LRG for GC, admitted to Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from March 2021 to March 2022, were retrospectively analyzed. Among them, 66 patients received a multimodal analgesic management based on ERAS (ERAS group), and 62 patients were treated with conventional mode of analgesia (control group). Pain levels, rehabilitation status, as well as inflammatory factors and stress response indicators before and after surgery were compared between the two groups. Results: There was no significant difference in baseline data between the two groups (P&gt;0.05). The postoperative pain and recovery in the ERAS group were better than those in the control group (P&lt;0.05). After the surgery, serum levels of tumor necrosis factor-alpha (TNF-α), Interleukin 6 (IL-6), and C-reactive protein (CRP) in both groups increased compared to before the surgery, but were significantly lower in the ERAS group compared to the control group (P&lt;0.05). After the surgery, serum malondialdehyde (MDA) and xanthine oxidase (XOD) levels in both groups increased, while superoxide dismutase (SOD) levels decreased compared to preoperative levels. The observed postoperative levels of serum MDA and XOD were significantly lower in the ERAS group, while the postoperative SOD levels were higher compared to the control group (P&lt;0.05). Conclusions: Patients undergoing LRG for GC can benefit from a multimodal pain management plan based on ERAS to reduce postoperative pain, alleviate inflammation, stress responses, and shorten the postoperative recovery process. doi: https://doi.org/10.12669/pjms.40.10.10088 How to cite this: Xu L, Yao L, Qin J, Xu H.

Impact of Applying PDCA Circulation Method on Surgical Care Interventions in the Operating Room on Patients Undergoing Cardiothoracic Surgery: A Retrospective Study

Background: The Plan-Do-Check-Act (PDCA) cycle is a widely recognized methodology for continuous quality improvement. This study evaluated the impact of applying the PDCA cycle on surgical care interventions in the operating room for patients undergoing cardiothoracic surgery. Methods: A retrospective study was conducted on the treatment of patients who underwent continuous cardiothoracic surgery in our Hospital from July 2020 to June 2023. Participants were divided into control and PDCA groups on the basis of the application of the PDCA cycle in their surgical care. Various outcomes were assessed, including psychological well-being (Hospital Anxiety and Depression Scale [HAMA] and Hamilton Depression Rating Scale [HAMD] scales), quality of life (using the QLQ-C30 tool), patient satisfaction, incidence of adverse accidents, clinical parameters, and laboratory measures. Results: The study comprised 133 patients, with 62 in the control group and 71 in the PDCA group. The psychological well-being, as measured by the HAMA and HAMD scales, of the PDCA group showed significant improvements compared with that of the control group (p &lt; 0.05). The Quality-of-Life scores were higher in the PDCA group than in the control group (p &lt; 0.05). In the PDCA group, the patient satisfaction scores related to hospital satisfaction were significantly higher than that in the control group, and the incidence of adverse accidents was lower (all p &lt; 0.05). No significant differences were noted in clinical parameters (ejection fraction and B-type natriuretic peptide levels) nor laboratory measures (serum protein and C-reactive protein (CRP) levels) between the groups (p &gt; 0.05 for all). Conclusion: The implementation of the PDCA cycle in the operating room for patients undergoing cardiothoracic surgery significantly improved psychological well-being and patient satisfaction and reduced the incidence of adverse accidents in the operating room, indicating that this quality improvement approach can enhance patient care experience. Although no significant differences were observed in clinical and laboratory parameters, the findings suggest that the PDCA cycle's strengths lie in its systematic approach to care process optimization and patient-centered outcomes.

COMPARATIVE CHARACTERISTICS OF THE INFORMATIVENESS OF THE LAL TEST AND PROCALCITONIN IN THE DIAGNOSIS OF INFECTIOUS COMPLICATIONS IN ACUTE ALCOHOLIC PANCREATITIS

Acute pancreatitis (AP) is an inflammatory condition of the pancreas, characterized by acute, intense abdominal pain. AP accounts for 20-30% of hospitalizations due to abdominal symptoms. The incidence of AP is increasing globally by 2-5% annually, ranging from 3.4 to 73.4 cases per 100,000 people. A critical concern in AAP is the potential development of infectious complications, which may require surgical intervention and increase mortality rates. Effective management and monitoring of these complications are essential. Research Justification. The diagnosis of AAP in clinical practice commonly relies on serum levels of α-amylase, lipase, C-reactive protein, and leukocyte counts. However, these markers have limitations and do not fully reflect the level of intoxication. The accuracy of C-reactive protein as a marker is not well established and is used mainly as a prognostic indicator. Serum α-amylase levels tend to decrease sharply after the fifth day of illness, regardless of the patient's condition. Lipase levels in diabetic patients can exceed reference values even without pathology, necessitating adjustments for AAP diagnosis. These criteria are most effective during the enzymatic phase of AAP (days 1-5). To predict the course of AAP and assess the adequacy of therapy, as well as to determine the need for surgical intervention, serum procalcitonin levels are commonly used. However, some studies question the diagnostic accuracy of procalcitonin, particularly regarding its correlation with organ failure, infectious complications, and patient mortality. Materials and Methods: This study involved 55 AAP patients, 51 men (92.7%) and 4 women (7.3%), with an average age of 49.49±9.87 years. Patients were categorized based on the severity of their condition: moderate (39 patients, 70.9%) and severe (16 patients, 29.1%). The control group consisted of 10 healthy individuals (9 men, 90.0%; 1 woman, 10.0%; average age 45.22±7.55 years). AAP was classified according to the Atlanta classification of acute pancreatitis. The study included patients with moderate to severe AAP who were hospitalized within 48 hours of symptom onset. All patients received treatment according to clinical guidelines, including intensive fluid therapy with Ringer's lactate. The Limulus Amebocyte Lysate (LAL) test and procalcitonin levels were measured on days 5, 8, 11, and 14 of hospitalization. For suspected infected necrosis, patients underwent contrast-enhanced computed tomography (CT) on day 14, with fine-needle aspiration biopsy or surgical intervention if necessary. Results. On day 5, LAL test values in the moderate and severe AAP groups were within reference ranges, and procalcitonin levels did not exceed 0.5 ng/ml. By day 14, a significant increase in LAL test values was noted in both groups, with a corresponding rise in procalcitonin levels. The ROC analysis for LAL test values on day 14 in the moderate AAP group showed an area under the curve (AUC) of 0.966, with 92.86% sensitivity and 96% specificity. For procalcitonin, the AUC was 0.723, with 71.43% sensitivity and 92% specificity. Conclusion. The LAL test is a sensitive and specific marker for detecting endotoxemia and monitoring the progression of AAP, particularly in predicting the development of infectious complications. The study demonstrates that LAL test values significantly correlate with the severity of AAP and may provide better diagnostic accuracy than procalcitonin, especially in the later stages of the disease.

Association between serum vitamin D, uric acid, C-reactive protein, and disease severity in ulcerative colitis: A retrospective study.

Ulcerative colitis (UC) is an inflammatory disease of the intestinal mucosa, and immunodeficiency is the main cause. Vitamin D (VD) has been shown to regulate many immune diseases, and studies have found that the level of uric acid (UA) and C-reactive protein (CRP) may also affect the severity of UC. This study aimed to investigate the correlation between VD levels and disease severity in UC patients. To determine serum VD levels in patients with UC of different ages and genders in China, and to study its correlation with UC, and to analyze its correlation with serum UA levels and CRP, so as to provide guidance for the prevention, diagnosis, and treatment of UC. One hundred three UC patients (64 males and 39 females, aged 16-75 years) were diagnosed with varying severity (mild, moderate, and severe). Serum VD levels, UA levels, and CRP levels were measured by electrochemiluminescence. The serum VD level of patients with severe UC was significantly lower than that of patients with mild UC. Gender was significantly correlated with serum UA, CRP, and disease severity in UC patients. Serum VD levels may affect the disease severity of UC patients, and patients with low serum VD content may have more severe disease. Gender affects serum UA, CRP, and disease severity. Males have significantly higher serum UA and CRP levels than females, while disease severity is generally lower than that of females. However, the mechanism of abnormal serum vitamin and trace element levels in UC patients remains to be further studied.

Effects of probiotic and vitamin D co-supplementation on clinical symptoms, mental health, and inflammation in adult patients with migraine headache: a randomized, triple-blinded, placebo-controlled trial

BackgroundMigraine headache is a major public health problem. Routine medications for migraine treatment are not useful in treating all patients and may have some side effects. The present study aimed to investigate the effect of vitamin D and probiotic co-supplementation on clinical characteristics of migraine, daily functioning, mental health outcomes, and serum levels of high-sensitivity C-reactive protein (hs-CRP).MethodsIn this randomized, triple-blinded, placebo-controlled trial, patients aged 18 to 55 years diagnosed with migraine based on the International Classification of Headache Disorders-3 (ICHD-3) were randomized to either vitamin D (50,000 IU every 2 weeks) plus probiotic (4.5 × 1011 CFU per day) or placebo for 12 weeks. The Headache Impact Test (HIT-6) and Depression, Anxiety, and Stress Scale (DASS) questionnaires were administered to patients at baseline and after 12 weeks. In addition, the frequency, duration, and severity of migraine headaches per month were assessed using a self-administered 30-day headache diary at baseline and the end of the intervention. Anthropometric indices, blood pressure, and serum levels of 25-hydroxy vitamin D and hs-CRP were also examined at first and the end of the study.ResultsSeventy-two migraine patients with a mean age of 37.46 ±\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\pm$$\\end{document} 8.32 years were included in this trial.

No significant difference was found between the two arms of the intervention regarding the change in headache duration, hs-CRP, scores of DASS, and HIT-6 questionnaires (P > 0.05).ConclusionsThis trial showed that probiotic and vitamin D co-supplementation for 12 weeks has beneficial effects on migraine headache characteristics. Further research is needed to confirm this finding.

Inflammation scores based on C-reactive protein and albumin predict mortality in hospitalized older patients independent of the admission diagnosis

Systemic inflammation significantly increases the risk of short- and long-term mortality in geriatric hospitalized patients. To predict mortality in older patients with various age-related diseases and infections, including COVID-19, inflammatory biomarkers such as the C-reactive protein (CRP) to albumin ratio (CAR), and related scores and indexes, i.e. Glasgow Prognostic Score (GPS), modified GPS (mGPS), and high sensitivity (hs)-mGPS, have been increasingly utilized. Despite their easy affordability and widespread availability, these biomarkers are predominantly assessed for clinical purposes rather than predictive applications, leading to their underutilization in hospitalized older patients. In this study, we investigated the association of CAR, GPS, mGPS, and hs-mGPS with short-term mortality in 3,206 geriatric hospitalized patients admitted for acute conditions, irrespective of admission diagnosis. We observed that unit increases of CAR, and the highest classes of GPS, mGPS, and hs-mGPS were significantly associated with a two- to threefold increased risk of death, even adjusting the risk for different confounding variables. Interestingly, a hs-mGPS of 2 showed the highest effect size. Furthermore, gender analysis indicated a stronger association between all CRP-albumin based parameters and mortality in men, underscoring the gender-specific relevance of inflammation-based circulating parameters in mortality prediction. In conclusion, scores based on serum CRP and albumin levels offer additional guidance for the stratification of in-hospital mortality risk in older patients by providing additional information on the degree of systemic inflammation.

Predictive Accuracy of C-reactive Protein as an Early Indicator of Leakage After Anastomosis and Primary Repair in Gastrointestinal Surgery.

Background Anastomotic leakage after gastrointestinal surgery is a significant postoperative complication that leads to increased morbidity and mortality. C-reactive protein (CRP) has been used previously as a predictive marker of anastomotic leakage in gastrointestinal surgeries. Its short half-life makes it a reliable marker for postoperative complications, rapidly returning to normal values as the patient recovers. We conducted this study to evaluate the predictive accuracy of serum CRP levels in predicting anastomotic leaks in patients undergoing gastrointestinal repair surgeries. Methods Ninety-six gastrointestinal surgeries involving anastomoses and primary repairs were included in the study. CRP was taken serially from postoperative days (POD) 1 to 7. Patients were divided into two groups based on postoperative outcomes: leakage and non-leakage. The receiver operating characteristic (ROC) curve of CRP levels with leak and mortality was plotted to find a threshold value for leak and mortality. Results Out of 96 patients included in the study, Group B (non-leakage) consisted of 78 patients (81.3%), while Group A (leakage) comprised 18 patients (18.7%). ROC analysis identified a CRP cutoff of 127 mg/L on POD 5, with high sensitivity (80%) and high specificity (80%) indicating a high likelihood of leakage above this threshold. Conclusion This study underscores the importance of monitoring CRP levels in the postoperative period, particularly on POD 5, as a non-invasive and cost-effective tool for the early detection of anastomotic leaks.

Application of serum SAA, CRP, PCT, WBC and N% in the diagnosis of neonatal septicemia

To explore the application value of SAA (serum amyloid A), CRP (C reactive protein), PCT (procalcitonin), WBC (white blood cell) and N% (neutrophil %) in the diagnosis of neonatal septicemia. This study was a retrospective study. 173 children with clinically diagnosed septicemia and 66 children with definitely diagnosed septicemia admitted to the Department of Neonatology, the Affiliated Changsha Central Hospital, Hengyang Medical School, University of South China,from January 2022 to January 2024 were selected as the case group, and 148 children with neonatal jaundice who were hospitalized during the same period were selected as the control group. Fasting venous blood was collected within 24 hours after the children's admission to detect the levels of serum WBC, N%, SAA, CRP and PCT. One-way analysis of variance and Kruskal-Wallis H test were used to compare the general data and inflammatory index levels of the three groups of children. The correlation analysis between SAA and other inflammatory indicators was conducted using Spearman correlation analysis. The receiver operating characteristic (ROC) curve was used to determine the diagnostic efficacy of different inflammatory indicators for patients with definitely diagnosed septicemia and those with clinically diagnosed septicemia, and for those with clinically diagnosed septicemia and those without infection. The results showed that the levels of WBC [(16.88±5.64)×109/L], N% [70.00 (63.00, 75.00)], PCT [2.22 (1.20, 5.55) mg/L], CRP [3.00 (0.50, 10.30) mg/L], SAA [19.70 (10.82, 49.90) mg/L] in the clinically diagnosed septicemia group and WBC [(16.10±7.48)×109/L], N% [73.50 (61.50, 80.93)], PCT [5.35 (0.69, 20.07) mg/L], CRP [15.52 (4.98, 30.50) mg/L], SAA [43.95 (14.00, 175.98) mg/L] in the definitely diagnosed septicemia group were all higher than those in the control group (11.17±3.38)×109/L, 49.81 (36.93, 62.75), 0.20 (0.07, 0.99) mg/L, 0.54 (0.20, 1.40) mg/L, 5.15 (3.60, 8.68) mg/L, and the differences were all statistically significant (all P<0.05). Spearman correlation analysis showed that the level of SAA was positively correlated with WBC, N%, PCT and CRP (rs=0.453, 0.540, 0.343, 0.550, all P<0.05). ROC curve analysis showed that the area under ROC curve(AUC) of SAA for the definitely diagnosed septicemia group and the clinically diagnosed septicemia group was higher than that of other inflammatory indicators, among them, the AUC of SAA for diagnosing the definitely diagnosed neonatal septicemia group was 0.933 (95%CI: 0.809-1.000, P<0.05), with a sensitivity of 92.90% and a specificity of 99.30%. The AUC of SAA for diagnosing the clinically diagnosed septicemia group was 0.861 (95%CI: 0.818-0.904, P<0.05), with a sensitivity of 83.20% and a specificity of 81.80%. In conclusion, compared with CRP, PCT, WBC and N%, SAA has higher sensitivity and specificity for distinguishing neonatal septicemia (including definitely diagnosed septicemia and clinically diagnosed septicemia), and has certain auxiliary diagnostic value for neonatal septicemia.

The Prospective Analysis of Biomarkers in Sepsis: Correlation With Clinical Outcomes.

Background Sepsis is a medical emergency and necessitates immediate diagnosis and treatment to prevent the progression to severe sepsis, septic shock, and potentially mortality. Aim This study aims to study the diagnostic significance of conventional and new markers, interleukin-10 (IL-10), in predicting the severity of sepsis. Methodology A prospective observational study was conducted in the department of surgery in a tertiary care hospital in Pune, India. The study included 100 patients diagnosed with a quick Sequential Organ Failure Assessment (qSOFA) score of ≥2. Serum C-reactive protein (CRP), procalcitonin (PCT), and interleukin-10 (IL-10) levels were measured. Receiver operating characteristic (ROC) curves were plotted to assess the diagnostic performance of these biomarkers. Results The mean serum CRP level on day 7 was significantly higher than the baseline, day 1, and day 3 groups (p=0.0001). On analysis by repeated measure, the ANOVA test revealed that the mean CRP levels on day 7were significantly higher. The mean PCT levels on day 7, day 3, and day 1 groups were significantly lower than those on day 1, day 2, and day 2, respectively (p=0.0001). The mean p-value of 3.3 g/L CRP was significantly lower on day 1 than that on day 3. IL-10 levels showed a significant upward trend, rising from 5.21 pg/mL at baseline to 7.57 pg/mL by day 7, with a p-value of <0.0001. Our cohort population showed elevated IL-10 values on the day of admission in a total of 15 patients. In our study, we observed that 11 patients with elevated IL-10 levels progressed towardmultiple organ dysfunction syndrome (MODS) and four mortalities. IL-10 is a crucial marker for identifying patients with worsening surgical sepsis. Conclusion IL-10, CRP, and PCT have potential as prognostic markers in assessing and predicting disease severity.The dynamic changes in these biomarkers correlate strongly with clinical outcomes, suggesting their role in guiding treatment decisions.

6545 Weekly Somapacitan Reduces Serum C-reactive Protein Levels in Adult Patients with Growth Hormone Deficiency

Abstract Disclosure: Y. Seki: None. S. Morimoto: None. M. Ikemoto: None. N. Takano: None. K. Yamashita: None. K. Bokuda: None. D. Watanabe: None. A. Ichihara: None. Background: Adult growth hormone deficiency (GHD) is known to be associated with increased inflammation. Our previous research revealed a significant association between GHD and elevated serum C-reactive protein (CRP) levels. Limited studies have demonstrated a significant association between GH replacement therapies and CRP levels; only two reports showed a significant reduction in serum CRP levels with daily somatropin. This study aimed to investigate the effects of weekly somapacitan on serum CRP levels in adult patients with GHD. Methods: We prospectively observed serum CRP levels as the primary outcome before and 6 months after somapacitan treatment in adult patients with GHD with no history of GH supplementation therapy within the past 6 months. Secondary outcomes included anthropometric data, IGF-1 levels, and kidney and liver functions. The somapacitan dose was titrated based on IGF-1 levels during the 6-month treatment period. Results: Eight adult patients (mean age 50±17, male 4 [50%]) with GHD received weekly somapacitan treatment. Of the patients, 2 (25%) had ACTH deficiency, 2 (25%) had TSH deficiency, and 2 (25%) had gonadotropin deficiency. Two patients (25%) were on glucocorticoid replacement. The somapacitan dose at 6 months was 1.9 (1.5-2.6) mg/week. Weekly somapacitan significantly increased serum IGF-1 level (48 [29-122] to 125 [63-205] ng/mL, P = 0.001) and IGF-1 SD score (-3.3 [-5.3-0.9] to -0.7 [-3.0-0.8], P = 0.008) and significantly decreased serum CRP level (0.243 [0.056-0.464] to 0.093 [0.036-0.290] ng/mL, P = 0.008). However, it did not affect body weight (80.6±11.6 to 79.8±10.5 kg, P = 0.67) or serum creatinine (0.74±0.13 to 0.68±0.21 mg/dL, P = 0.35) and alanine aminotransferase (60 [20-99] to 48 [21-85] U/L, P = 0.23) levels. Changes in CRP levels were significantly correlated with changes in IGF-1 levels (rs = -0.83, P = 0.010) and IGF-1 SD scores (rs = -0.79, P = 0.021). Conclusion: GH supplementation therapy with weekly somapacitan reduced serum CRP levels in adult patients with GHD without affecting body composition or kidney and liver functions.

The Effect of Metformin Therapy on Serum IL-33 and ST-2 Receptor Levels in Patients With Type 2 Diabetes Mellitus

Introduction: Patients with type 2 had elevated levels of inflammatory biomarkers, including interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF-α). Significant elevations in serum levels of TNF-α and C-reactive protein were seen in individuals with type 2 diabetes mellitus (T2DM). The IL-1 superfamily (IL-1β, IL-18, and IL-33) plays a crucial role in the development of diabetes mellitus by modifying immunological and inflammatory immune responses. Objectives: Little is known about the role of metformin in type 2 diabetes mellitus with respect to serum levels of IL-33 and ST-2 receptors. Therefore, in the present study, we sought toexplore such role. Patients and Methods: This single arm study included 45 type 2 diabetes patients with an age range of 30 to less than 60 years. Patients were given metformin (500 mg orally; for two months then, serum level of interleukin- 33 (IL-33) and ST-2 receptors were evaluated. Results: Treatment resulted in significant reduction of serum the suppression of tumorigenicity suppressor 2 (ST2) from 0.71 ±0.157 µg/mlto 0.59 ±0.11 µg/ml (p&lt;0.001), across with significant increase in serum IL-33 from 0.60 ±0.18 pg/ml to 0.75 ±0.13 pg/ml (p &lt; 0.001). Conclusion: Treatment of type 2 diabetes mellitus using metformin revealed a crucial role for IL-33 and ST-2 receptors in glycemic control since increment in IL-33 and reduction in ST-2 receptors were associated with good glycemic control suggesting an inflammatory role in disease pathogenesis and response to treatment.

Evaluating The Factors Affecting Mortality and Survival of the Patients Who Underwent Percutaneous Endoscopic Gastrostomy; The Short-term and Long-term Results

Summary Aim Percutaneous endoscopic gastrostomy (PEG) is a common minimally invasive technique performed in patients with oral feeding problems. The aim of the current study is to evaluate the associated factors that have an impact on the short- and long-term survival and mortality in these patients who received PEG tube placement. Materials and Methods The patients who underwent PEG placement between June 2020 and June 2023 are enrolled in the study. Mortality data was extracted from the National Death Registry database. Data regarding the demographics, indications of PEG, co-morbidities, length of hospital stay prior to PEG procedure, the need for mechanical ventilator support, body-mass index, serum levels of hemoglobin, leukocyte, albumin, and c-reactive protein are extracted retrospectively. Kaplan Meier and Cox regression analyses were used to evaluate the factors affecting survival. Results A total of 137 patients are enrolled in the study (71 female and 66 male). One-month mortality was 16.7% and overall mortality during a follow-up of 38 months was 51%. Survival was significantly higher in patients with motor neuron diseases than the patients with Alzheimer’s (p=0.036). Length of hospital stay before PEG placement and hemoglobin levels were found to have a significant impact on survival in Cox regression analysis (p=0.000, p=0,009). Conclusion Length of hospital stay before PEGplacement, need for mechanical ventilator support and hemoglobin levels were found significantly associated with survival. Higher mortality in Alzheimer's patients may indicate that indications of PEG should be re-evaluated in these patients.

Serum ferritin and C- reactive protein levels as indicators of severity of preeclampsia.

To assess the role of inflammatory markers ferritin and C- reactive protein as indicators of preeclampsia severity. The case-control study was conducted at Al-Yarmouk Teaching Hospital, Baghdad, Iraq, from November 2021 to May 2022, and comprised pregnant women from the obstetrics ward and outpatient clinics aged 16-40 years having a viable singleton pregnancy and gestational age >32 weeks. They were divided into severe preeclampsia group A, non-severe preeclampsia group B and control group C. Serum ferritin and C-reactive protein levels were measured for all the subjects, and compared. Data was analysed using SPSS 26. Of the 87 pregnant women, 27(31%) were in group A with mean age 29.76±7.53 years and mean gestational age 35.63±1.92 weeks, 29(33.33%) were in group B with mean age 26.83±6.30 years and mean gestational age 36.24±1.72 weeks, and 31(35.63%) were in group C with mean age 26.00±5.73 years and mean gestational age 36.52±1.61 weeks. Ferritin levels in patient groups were significantly higher than in the control group (p<0.05), but it was not significantly different between the patient groups (p>0.05). C-reactive protein levels in the patient groups were significantly higher than in the control group (p<0.05), and they were also significantly higher in group A than in group B (p<0.05). At a cut-off value >101.8 ferritin had sensitivity 92.59% but specificity 20.69%, whereas C- reactive protein at a cut-off value >17.1 had sensitivity 66.67% but specificity 75.86%. Serum C- reactive protein level was significantly associated with severity of preeclampsia with an acceptable grade of discriminative ability between severe preeclampsia and non-severe preeclampsia patients.

The role of C-reactive protein as a risk marker of postoperative delirium in older hip fracture patients: a prospective cohort study.

Postoperative delirium (POD) is a common and serious neuropsychiatric syndrome that leads to higher morbidity and mortality. We investigated the association between serum C-reactive protein (CRP) and the occurrence of POD in older hip fracture patients, and whether CRP predicted POD better than a clinical model. Patients aged ≥ 75years admitted for surgical repair of an acute hip fracture were recruited. We compared serum CRP levels between patients with and without POD. Sixty patients were included, of whom 21 (35%) developed POD. Serum CRP levels were significantly higher in patients who developed delirium (p = 0.011). In a multiple regression model including clinical variables and CRP, cognitive impairment (p = 0.003) and infection (p = 0.001) were the best predictors of POD. Although higher levels of serum CRP were significantly associated with POD in older hip fracture patients, pre-existing cognitive impairment and infections were the most important risk factors for POD.

Anti-inflammatory potential of polyphenols: Combining in silico prediction and in vivo data

Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by joint inflammation and destruction, leading to significant pain and disability. Adenosine deaminase (ADA) is identified as a biomarker for RA’s inflammatory process. This study aims to investigate the potential of flavonoids and phenolic acids to inhibit ADA activity (in silico) and evaluate their anti-inflammatory effects in a RA model (in vivo). Methods: The molecular docking study was conducted using YASARA Structure 19.12.14. software following the Auto Dock 4.2 protocol. A rat model with pristane-induced arthritis was used to test the anti-inflammatory effect of selected polyphenols. The consistency of the development of the rat model was evaluated through the following indicators artistic score, paw volume, and body weight. Quercetin was administered intragastrically at doses of 150 and 400 mg/kg over 15 days. The C-reactive protein (CRP) level in serum was measured with an automatic biochemical analyzer. Statistical analyses were performed using SPSS 29.0.2.0. Results: Molecular docking simulations showed flavonoids inhibited ADA activity with inhibition constants ranging from 0.012 mM to 0.190 mM. In the in vivo RA model, quercetin significantly reduced joint inflammation and serum CRP levels at a higher dose of 400 mg/kg. Conclusion: Quercetin shows promise as an anti-inflammatory agent for RA by targeting ADA, suggesting that flavonoid-rich plant extracts could enhance RA treatment.
