Involvement of β-catenin expression in hepatocellular carcinoma prognosis in a cohort of patients undergoing curative treatment

BackgroundHepatocellular carcinoma is a tumor of epithelial origin that arises from the action of different carcinogens on the hepatocytes and has a high worldwide incidence. The prognostic markers of this disease have not been completely established. Mutations in the gene encoding β-catenin are overexpressed in hepatocellular carcinoma. The objective of our study was to correlate the molecular expression of β-catenin in hepatocellular carcinoma with the already known prognostic markers. MethodsWe conducted an observational and prospective cohort study on adult patients diagnosed with hepatocellular carcinoma from whom samples of nontumor and tumor liver parenchyma were taken intraoperatively to correlate the molecular expression of β-catenin in hepatocellular carcinoma with the known prognostic markers. ResultsA total of 81 samples were collected, of which 48 met the inclusion criteria. The final sample was divided into patients with a diagnosis of hepatocellular carcinoma on a cirrhotic liver, corresponding to 31 patients (64.6%), and patients with a diagnosis of hepatocellular carcinoma on a noncirrhotic liver, corresponding to 17 patients (35.4%). We found that overexpression of β-catenin and the neutrophil/lymphocyte ratio are independently related to disease-free survival, and both overexpression and molecular repression of β-catenin are independently related. ConclusionMolecular overexpression of β-catenin in hepatocellular carcinoma compared with nontumor tissue is associated with worse disease-free survival, and its combination with a high neutrophil-lymphocyte ratio worsens this prognosis.

The Prognostication of Surgically Resected Head and Neck Squamous Cell Carcinoma Using Pre-Therapy Neutrophil and Lymphocyte Counts.

Hematological markers, such as neutrophils (ANC), lymphocyte (ALC), and neutrophil-lymphocyte ratio (NLR), may serve as indicators of systemic inflammation and immune response in head and neck squamous cell carcinoma (HNSCC). However, their prognostic significance across HNSCC subtypes remains to be fully elucidated. We conducted a secondary analysis of a randomized clinical trial involving patients with surgically resected HNSCC with either positive margins or extranodal extension. These patients received either adjuvant chemoradiation with or without lapatinib. We explored the correlation between pre-therapy ANC, ALC, and NLR levels and overall survival (OS) as well as disease-free survival (DFS). A sub-group analysis examined potential links between these markers, primary tumor location, and HPV status. Of the 688 patients in the trial, we included 681 patients with documented pre-therapy ANC and ALC values. High pre-therapy ANC and ALC were significantly associated with reduced OS (HR, 1.56; 95% CI: 1.19-2.05) and (HR, 1.34; 95% CI: 1.01-1.79), respectively. High NLR did not significantly affect OS (HR, 1.09; 95% CI: 0.81-1.47). Subgroup analysis indicated significantly reduced OS in patients with high ANC across oropharyngeal, non-oropharyngeal, and HPV-negative subtypes. High ANC, ALC, and NLR did not impact DFS notably. Elevated pre-therapy ANC is strongly associated with decreased survival across all patients and subgroups, ALC was only significant in the general patient analysis. NLR's association with reduced OS was not statistically significant. These biomarkers may provide greater prognostic value in patients with oropharyngeal cancer and seemed to be more strongly associated with OS than DFS.

Complete Blood Collection-based Systemic Inflammation Biomarkers as a Severity Biomarker in Alopecia Areata: A Cross-sectional Study.

Previous studies have suggested that alopecia areata (AA) is an organ-specific disease characterized by loss of immune privilege of hair follicles. However, an increasing body of research indicates that it not only affects the skin but may also be accompanied by systemic inflammatory reactions. Therefore, searching for simple and easily available biomarkers to describe the underlying systemic inflammation in AA patients is of great clinical significance. Complete blood collection-based systemic inflammation biomarkers have been shown to be associated with the severity and prognosis of various skin and autoimmune diseases. They involve multiple cell lineages and can reveal different pathways of immune-inflammatory responses. The aim of this study was to investigate the level of complete blood collection-based systemic inflammation biomarkers in patients with AA, and to analyse their relationship with the disease severity. A total of 302 AA patients and 296 healthy controls were included in this study and the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), systemic immune inflammation index (SII), and white blood cell/lymphocyte ratio (WLR) were calculated. The differences in these indicators between the 2 groups were compared, and the relationship between NLR, PLR, SII, WLR, and the risk of severe AA were analysed. AA patients had higher NLR, SII, and WLR compared with healthy controls (p = 0.004, 0.002, and 0.002 respectively). PLR and SII were higher in the severe AA group compared with the mild-to-moderate AA patients (p = 0.005 and 0.011 respectively). The risk of severe AA increased with the increasing of PLR, SII, NLR, and WLR (p for trend was 0.001, 0.006, 0.022, and 0.021, respectively). The levels of systemic inflammation biomark-ers in AA patients are higher than in healthy people. NLR, PLR, SII, and WLR are risk factors for severe AA, suggesting a close association between systemic inflammation and disease occurrence in AA patients.

Prognostic Evaluation of Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) Score and Hematological Indices in Classic Hodgkin Lymphoma.

Hodgkin lymphoma (HL) constitutes 10% of all lymphoma diagnoses and accounts for 5% of lymphoma-related deaths. Accurate prognostication in HL remains crucial, particularly given that 10%-20% of patients may receive either insufficient or excessive treatment. This study investigates the effect of hemoglobin, albumin, lymphocyte, and platelet (HALP) score, which is a marker of inflammation status and nutrition, at the time of diagnosis for the patients with HL on prognosis. A total of 147 patients diagnosed with cHL were included in the study, and their data were analyzed retrospectively. The significance of the HALP score and hematological indices [neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), and platelet-lymphocyte ratio (PLR)] as predictors of overall survival (OS) and disease-free survival (DFS) was evaluated. Patients were grouped according to median values for the HALP score and hematological indices. High HALP score (p = 0.034), low NLR (p = 0.033), high LMR (p = 0.003), and low PLR (p = 0.014) were statistically significant in the early-stage favorable group. DFS and OS were not statistically significant according to the HALP score NLR, LMR, and PLR groups. The need for readily applicable, reliable prognostic markers in cHL, where immunotherapy treatments have led to significantly improved survival outcomes, remains persistent.

Association of baseline neutrophil-to-lymphocyte ratio and prognosis in melanoma patients treated with PD-1/PD-L1 blockade: a systematic review and meta-analysis

Immunotherapy treatments that target programmed cell death receptor-1 (PD-1) or its ligand (PD-L1) have revolutionized the treatment of metastatic melanoma and currently represent the standard first-line treatment for this type of cancer. However, it is still not entirely clear which biomarkers are cost-effective, simple, and highly reliable. This systematic review and meta-analysis aims to analyze the predictive value of the baseline neutrophil-lymphocyte ratio (NLR) regarding disease progression and overall survival of patients with metastatic melanoma undergoing treatment with PD-1/PD-L1 blockade. PubMed, Scopus, and Web of Science were searched for studies comparing high versus low NLR. We performed the meta-analysis using RStudio v4.4.2 software. A total of 20 studies and 2691 patients were included, all with diagnoses of melanoma. The majority of the individuals were male 2278 (84, 65%). The median overall survival (OS) and progression-free survival (PFS) ranged from 5.0 to 44.4 and from 1.8 to 15.0 months, respectively. Compared with the high NLR ratio, the low exposure group achieved better rates of OS [hazard ratio (HR), 2.07; 95% CI, 1.73–2.48; P < 0.00001; I² = 47%]. Regarding PFS, there was a statistically significant difference between groups with tendencies toward the low NLR exposure group (HR, 1.59; 95% CI, 1.39–1.81; P < 0.00001; I²=31%]. This systematic review and meta-analysis revealed significant lower OS in melanoma patients treated with PD-1/PD-L1 blockade who had elevated baseline NLR values. Furthermore, an increased PFS was observed in patients with a lower baseline NLR value. This study highlights NLR as an important prognostic biomarker for patients with metastatic melanoma who are candidates for treatment with PD-1 and PD-L1.

Establishment of a clinical model based on vessels encapsulating tumour clusters that could efficiently predict recurrence of patients with hepatocellular carcinoma after curative hepatectomy

According to previous studies, vessels encapsulating tumor clusters (VETC) could promote metastasis of hepatocellular carcinoma (HCC) in a manner independent from epithelial-mesenchymal transition (EMT). However, the prognostic significance of VETC among patients undergoing curative hepatectomy has not been fully explored. This study was performed to assess the prognostic significance of VETC among patients undergoing curative hepatectomy.81 patients undergoing curative hepatectomy were included in this study. A predictive model based on VETC was established. Then this predictive model based on VETC was compared with American Joint Committee on Cancer Tumor Nodal Metastasis (AJCC TNM) and Barcelona Clinic Liver Cancer (BCLC) system.It was revealed by multivariate Cox regression analysis that high neutrophil lymphocyte ratio (NLR) (P=0.013, HR=6.175, 95%CI: 1.468-25.977), number of tumors (P＜0.001, HR=4.119, 95%CI 1.886-8.995) and VETC positivity (P=0.010, HR=2.440, 95%CI 1.235-4.821) were independent predictive factors for disease-free survival (DFS). Additionally, by Kaplan-Meier analysis, we revealed that VETC positivity was associated with worse DFS (P=0.018). Then the clinical predictive model combining NLR, number of tumors, and VETC was compared with AJCC TNM stage and BCLC classification system by performing time-dependent receiver operating curve (td-ROC) analysis, revealing that the clinical predictive model was superior to AJCC TNM stage and BCLC system at different time points. Additionally, we demonstrated that the clinical model could well predict DFS by plotting calibration curves.VETC could be utilized as an efficient prognostic factor for HCC and the clinical predictive model combining NLR, number of tumors, and VETC was superior to AJCC TNM stage and BCLC system in predicting cancer recurrence.

IMPACT OF ANTIHYPERTENSIVE DRUGS ON C REACTIVE PROTEIN (HS-CRP) AND NEUTROPHIL LYMPHOCYTE RATIO (NLR)

Many studies showed the association between inflammation and Hypertension. Inflammatory markers may highlight the state of inflammation in hypertensive patients. This study aimed to investigate impact of antihypertensive drugs on high sensitive C-reactive protein (hsCRP) and neutrophil lymphocyte ratio (NLR). A comparative cross sectional study was conducted on 86 hypertensive patients attending cardiology outpatient clinic in Al-Gamhuoria Modern General Hospital, Aden, in the period from October to December 2023. Participants were divided into three groups: patients treated with mono-therapy from inhibitors of renin angiotensin aldosterone system (RAASI), patients treated with mono-therapy antihypertensive not acting on RAAS (NRAASI) and patients treed with combination of them (drug combination). Data on Age, Sex, BP level, BMI, duration of hypertension (HTN), family history of HTN, and medications used were collected. Blood samples for measuring HsCRP, neutrophils, lymphocytes were drawn. Descriptive statics and chi-square tests were used for data analysis. Almost equivalent distribution for males and females between groups, with a large proportion of the patients within each group laid in the age group 35-55 years. The median values of hypertension duration were 36, 48, and 54 months for RAASIs, NRAASIs and drug combination group, respectively. The target BP was obtained by 46.9% 45.5% and 50% of patients treated with RAASIs, NRAASIs and drug combination respectively. There was a statistically significant difference between SBP and DBP in patients with controlled BP and those with uncontrolled SBP levels and treated by different drug regimens (P=0.000 for each Bp level). There were significant differences between values of hs-CRP of patients with controlled (P=0.000) or uncontrolled (P=0.046) BP and treated with different modalities. The median differences in NLR between the groups were statistically significant; including groups of all patients P=.032, of patients having controlled BP P=0.014 as well as uncontrolled BP P=0.038. Comparing the uncontrolled of BP of the three groups we found the highest prevalence (9.3%)of patients with uncontrolled BP and had the lower level hsCRP (≤3mg /l) was in RAASIs group, while those with higher prevalence (11.6%) of uncontrolled BP and higher level of hs-CRP ( >3mg/l) was in drug combination group. In conclusion, hypertensive patients treated with RAASI, NRAASI and drug combination and reached BP target showed significant reduction in hsCRP and NLR. Patients with uncontrolled BP treated with RAASIs revealed slightly lower hs-CRP than other groups. Careful selection of antihypertensive drugs may affect risks of CVD. This study recommends further prospective studies exploring the anti-inflammatory effect of antihypertensive drugs to ameliorate possible risks of cardiovascular disease.

Prediction of the outcome of intracerebral hemorrhage by blood neutrophil to lymphocyte ratio; a prospective observational study

Introduction: Intra-cerebral haemorrhage (ICH) is defined as bleeding within the brain parenchyma. Neutrophil Lymphocyte ratio (NLR) is a dynamic parameter can be affected by underlying condition like microangiopathy (e.g. hemorrhagic stroke). The NLR value at the time of stress (e.g. ICH) could be predictor among various other factors on the outcome of the disease. The aim of this study is to see NLR could be predictor of the outcome of the ICH. Methods: This is a prospective observational study conducted in the Department of Neurosurgery and Department of Neurology, from March 2020 to February 2021. The ICH cases presented to the emergency department within 24 hours of symptoms were included. The baseline haematological and biochemical investigations were sent and the non-contrast computed tomography (NCCT) head was done for diagnosis of ICH. The NLR was measured. The ICH volume was calculated by ABC/2. Follow-up of the patient to measure outcome was done with a modified Rankin scale (mRS) on 30 days. Student’s t-test was used to correlate NLR-mRS. Fischer’s exact test was used for a categorical association of NLR to mRS. Results: A total of 89 patients with ICH were enrolled in this study. In this study, 62.92% of patients had good outcomes (NLR of 4.88 ±3.06), whereas 37.08% of patients had bad outcomes (NLR of 9.09 ± 4.92). Statistically, higher NLR was significantly predictive of poorer outcomes. Conclusions: ICH causes stress in the body, which alters the value of NLR. Components of NLR are altered after haemorrhage due to a change in homeostasis of brain parenchyma. NLR value obtained at the time of emergency department visits may help to predict the 30 days outcome of ICH.

Hyperprogressive disease in patients with advanced cancer treated with immune checkpoint inhibitors.

Hyperprogressive disease (HPD) is a new phenomenon developing in the era of immune checkpoint inhibitor (ICI) therapy. HPD is characterized by an unexpected and fast progression in tumor volume and poor survival. There is no standardized definition for HPD and clinicopathological variables associated with HPD are unclear. Herein, we assessed incidence, treatment outcomes and factors predictive of HPD in patients treated with ICIs. We retrospectively analyzed patients with advanced cancer treated with ICI at one academic center between 2014 and 2021. We used the Lo Russo's adopted criteria combined with clinical and radiologic parameters for the definition of HPD. All patients who underwent their first tumor evaluation according to RECIST1.1 were included. Of 155 patients, 147 were eligible for analysis. The median age was 61 and 83% were male. The cancer types were; lung 67.3%, bladder 12.9%, gastric 9.5%, 5, colon 5.4% and renal cell carcinoma 4.8%. 59.9% of patients were treatment-naive and others had one or more lines of chemotherapy. 19 (12.9%) patients had HPD. In patients who had HPD, progression-free survival (PFS) was significantly shorter (1.5 vs 9.8months, (HR 9.56; 95% CI (5.51-16.57), p < 0.001). The median overall survival (OS) was also shorter for HPD patients than non-HPD (3.0 vs 23.1months, respectively, HR 12.03, 95% CI (6.64-21.81), p < 0.001). Gastric cancer, larger sum of target lesion diameters at baseline, liver metastases, higher LDH level and higher neutrophil-lymphocyte ratio (NLR) were significantly associated with HPD. Our findings demonstrated that HPD was a rapid phenomenon with significantly poor survival rates. Several clinicopathological factors and tumor characteristics might indicate HPD.

Systemic inflammation and changes in physical well-being in patients with breast cancer: a longitudinal study in community oncology settings.

Chemotherapy adversely affects physical well-being and inflammation may be related to changes in physical well-being. We evaluated the association of systemic inflammation with changes in physical well-being. In a prospective study of 580 patients with stages I-III breast cancer we assessed immune cell counts, neutrophil:lymphocyte ratio (NLR), lymphocyte:monocyte ratio (LMR), and platelet:lymphocyte ratio (PLR) within 7 days before chemotherapy (pre-chemotherapy). Physical well-being was assessed using the Functional Assessment of Cancer Therapy: General-Physical Well-being subscale (FACT-PWB) pre-chemotherapy and 1 month and 6 months post-chemotherapy. Clinically meaningful decline in physical well-being was determined as decreasing FACT-PWB by more than one point from pre-chemotherapy level, and non-resilience defined as having decline post-chemotherapy and not returning to within one-point of pre-chemotherapy FACT-PWB by 6 months post-chemotherapy. Multivariable logistic regressions examined the association between inflammation and changes in physical well-being, adjusting for sociodemographic and clinical characteristics. Fifty-nine percent (310/529) and 36% (178/501) of participants had physical well-being decline post-chemotherapy and 6 months post-chemotherapy, respectively. Fifty percent (147/294) were non-resilient. Low NLR and PLR were associated with 1.78 (P = .01) and 1.66 (P = .02) fold greater odds of having a decline in physical well-being 6 months post-chemotherapy compared to those with high NLR and PLR, respectively. Low NLR and PLR were associated with 1.92 (P = .02) and 2.09 (P = 0.01) fold greater odds of being non-resilient 6 months post-chemotherapy compared to those with high NLR and PLR, respectively. Low NLR and PLR were associated with chemotherapy-induced changes in physical well-being independent of sociodemographic and clinical risk factors.

The relationship between inflammatory markers and retinopathy of prematurity in extremely premature infants.

This study aimed to evaluate the relationships among blood parameters, clinical factors, and retinopathy of prematurity (ROP) in extremely premature (EP) infants. This retrospective study included 153 EP infants who were categorized into two groups based on the presence of inflammatory diseases such as necrotizing enterocolitis, neonatal sepsis, bronchopulmonary dysplasia, severe intraventricular hemorrhage, preeclampsia, and premature rupture of membranes. Complete blood count parameters, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio, platelet-lymphocyte ratio (PLR), systemic inflammatory index, and platelet mass index were recorded during the first week and first month after birth. The study analyzed the impact of parameters obtained through blood tests during the first week and first month on the development of ROP and the requirement for treatment. In this study, 96 infants were diagnosed with inflammatory diseases. After multivariate regression analyses, the duration of mechanical ventilation (p = 0.010) was found to be the only factor that led to ROP development. Moreover, lower gestational age (GA) (p = 0.006), higher NLR (p = 0.026), and lower PLR (p = 0.019) were observed in infants requiring treatment compared to infants with spontaneous resolution of ROP in this group. 57 infants did not have inflammatory diseases. Although the duration of mechanical ventilation (p = 0.041) and low levels of platelets (PLT) (p = 0.046) measured in the first month postnatally were significantly found to be associated with ROP developement, no parameter affecting the required treatment could be determined. EP infants with longer mechanical ventilation durations and lower PLT counts are vulnerable to ROP development. GA, PLR, and NLR are predictive factors for treatment.

Ketamine combined with dexmedetomidine reduces neutrophil lymphocyte ratio (NLR) in critically ill COVID-19 patients; a pre-experimental study

Background &amp; objective: About 20% of patients with COVID-19 admitted to the intensive care unit (ICU) need ventilatory support under sedation using dexmedetomidine and ketamine. Ketamine has an anti-inflammatory effect and is expected to suppress immune cells. A high neutrophil-lymphocyte ratio (NLR) is associated with a severe stage of the disease. We compared NLR between COVID-19 patients under sedation with dexmedetomidine alone or with dexmedetomidine combined with ketamine. Methodology: This pre-experimental study involved a control group of patients receiving dexmedetomidine (n = 10) and the intervention group receiving dexmedetomidine and ketamine (n = 10) for sedation. NLR was evaluated before and after 24 h of sedation with the study drugs. Result: The patients' NLR increased significantly at 24 h after sedation using sole dexmedetomidine from 9.01 to 15.62 (P &gt; 0.05). The combination of dexmedetomidine and ketamine significantly reduced NLR from 11.22 to 8.61 (P = 0.026). Both groups experienced a decrease in neutrophil count (P &gt; 0.05). The lymphocyte count increased significantly in the intervention group (P = 0.025) and decreased in the control group. Conclusion: There is a significant NLR difference between a patient receiving dexmedetomidine sedation compared dexmedetomidine combined with ketamine. A combination of dexmedetomidine and ketamine reduces NLR compared to sole dexmedetomidine in critically ill COVID-19 patients.

Predictive value of early dynamic changes of NLR and PLR for the efficacy of immune checkpoint inhibitor in head and neck squamous cell carcinoma

We analyzed the predictive value of dynamic changes in neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) treated with immune checkpoint inhibitors (ICIs). A total of 104 patients with R/M HNSCC treated with ICIs during August 2018 to June 2023 were included. Dynamic changes were defined as the difference between NLR and PLR on day 1 of cycles 1 and 2. Patients with increased NLR or PLR had an independently increased risk of disease progression at the first response evaluation (odds ratio [OR] 5.26, P = .005; OR 2.29, P = .042), disease progression (hazard ratio [HR] 2.29, P = .003; HR 1.68, P = .027), and death (HR 1.86, P = .027; HR 1.68, P = .037). Furthermore, patients with a decrease in NLR showed longer progression-free survival, with HRs of 0.36 (P < .001) for those with low pre-ICI NLR and 0.52 (P = .041) for those with high pre-ICI NLR, compared to those with increased NLR. Increased NLR or PLR was associated with adverse outcomes after ICI treatment in patients with R/M HNSCC.

Weak association between urea-creatinine ratio and c-reactive protein with nutritional risk in hospitalized patients with COVID-19: A cross-sectional study

BackgroundCOVID-19 is a systemic infection with a significant impact on nutrition risk and the hematopoietic system. The neutrophil-lymphocyte ratio (NLR) may have prognostic value in determining severe cases of COVID-19 and the urea-creatinine ratio (UCR) is currently being studied as a potential biomarker of catabolism associated with critical illness. The aim was to assess the association between the NLR, UCR and C-reactive protein (CRP) with nutritional risk in hospitalized patients with COVID-19. MethodsThis is a retrospective cross-sectional study that assessed 589 hospitalized patients with COVID-19, 18 years of age or older, of both sexes. Nutritional risk was assessed by Nutritional Risk Screening (NRS, 2002) and NLR by neutrophils divided by lymphocyte count. The UCR was calculated by the ratio between urea and creatinine and quantified by the calorimetric biochemical method and CRP by the immunoturbidimetric method. Differences between groups were applied by the Mann-Whitney U test and the automated binary regression test. ResultsOf the 589 patients, 87.4% were at nutritional risk. When evaluating patients admitted to the ICU, 91.9% were at nutritional risk. Patients with NRS ≥3 are older, with lower body mass and BMI, higher NLR and UCR and lower CRP values. However, 73% of patients admitted to the ward were at nutritional risk, and only age differed between groups, being higher in patients with NRS ≥3. Logistic regression showed a weak association between nutritional risk in NRS and UCR (Model 1) (OR=0.96, p=0.003) and NRS with CRP (Model 1) (OR=1.01, p<0.001) in patients in the ICU. On the other hand, the logistic regression in ward patients found association only for CRP in both models (Model 1, OR=1.01, p=0.041) and (Model 2, OR=1.01, p=0.031). ConclusionWe found a low association between nutritional risk and UCR and CRP in patients admitted to the ICU, while in the ward patients the nutritional risk also had weak association with CRP.

Skeletal Muscle Index-Based Cachexia Index as a Predictor of Prognosis in Patients With Cancer: A Meta-Analysis and Systematic Review.

Cachexia is associated with poor survival rates. In the clinical setting, the diagnosis of cancer cachexia is challenging. The cachexia index (CXI), a new index for predicting survival time, is a promising tool for diagnosing cancer cachexia; however, its efficacy in predicting patient survival has not been validated. This meta-analysis and systematic review aimed to explore the CXI's prognostic value in patients with cancer. The PubMed, Embase, MEDLINE, and Cochrane Library databases were searched for relevant studies to determine the association between CXI findings and prognosis. The outcomes were overall survival (OS), progression-, disease-, and recurrence-free survival (PFS/DFS/RFS) rates, and the rate of complete response. The QUality In Prognostic Studies (QUIPS) tool was used to evaluate the quality of the included trials. This meta-analysis comprised 14 studies involving 2777 patients. A low CXI was associated with decreased OS (hazard ratio [HR] 2.34, 95% confidence interval [CI] 2.01-2.72; P < .001), PFS/DFS/RFS (HR 1.93, 95% CI 1.68-2.22; P < .001), and complete response (odds ratio [OR] 0.49, 95% CI 0.36-0.66; P < .001). Patients with a low CXI had a lower body mass index (mean difference [MD] -0.75, 95% CI -1.00 to 0.50; P < .001), skeletal muscle index (standardized MD -0.80, 95% CI -0.98 to -0.61; P < .001), and serum albumin level (MD -0.23, 95% CI -0.26 to -0.20; P < .001); and a higher neutrophil-lymphocyte ratio (MD 1.88, 95% CI 1.29-2.47; P < .001) and more advanced disease stages (OR 0.80, 95% CI 0.71-0.91; P = .001). A low CXI was found to be associated with poor survival in patients with cancer. While the CXI is a promising marker for predicting cancer cachexia, further studies are required to verify its usefulness.

Evaluation of Neutrophil-Lymphocyte Ratio as Inflammatory Marker in Chronic Kidney Disease Stage 3 and 4

Chronic kidney disease (CKD) is a worldwide health problem because of the significant morbidity and mortality which is mostly due to chronic inflammation and proteinuria. Early detection of inflammation and its proper management can prevent further CKD progression and complications. This study aims to observe the association of neutrophil-lymphocyte ratio (NLR) with inflammatory markers in chronic kidney disease stage 3 and 4. In this study, a total of 100 adult patients of CKD stage-3 and 4 were included as study subjects and patient with acute illness, known case of malignancy, cardiovascular and cerebrovascular disease were excluded from the study. From each patient all the relevant history, clinical and laboratory findings were recorded in the data collection sheet. Study subjects were divided into two groups according to NLR value; those who have NLR 0- 3 were in group normal NLR and subjects with NLR &gt;3 in group high NLR. Then markers of inflammation ESR, CRP and serum albumin were compared between these groups. Statistical analysis was done by Statistical Package for Social Science (SPSS) version 22.0. The mean ESR of male and female patients was higher in high NLR subjects than normal NLR subjects. The mean CRP was higher in high NLR subjects than normal NLR subjects. The mean serum albumin was lower in high NLR subjects than normal NLR subjects. The difference of mean ESR, CRP was statistically significant between high NLR and normal NLR subjects but difference of mean serum albumin was not statistically significant. The study findings suggest that high NLR is significantly associated with of inflammatory markers-ESR, CRP. Hence, it can be concluded that NLR could be used as an indicator of inflammation in CKD.

Elucidating the Relationship between Neutrophil-Lymphocyte Ratio and Plaque Composition in Patients with Drug-Eluting Stent Restenosis by Virtual Histology-Intravascular Ultrasound.

(1) Background: In-stent Restenosis (ISR) is a major factor influencing the prognosis and revascularization of target lesions. The plaque composition is unclear; therefore, it is critical to investigate ISR composition to identify clinical intervention markers. (2) Methods: This study was conducted on 36 patients with drug-eluting stent restenosis. The patients were classified into a Low Neutrophil-Lymphocyte Ratio (L-NLR) and High Neutrophil-Lymphocyte Ratio (H-NLR) according to the median NLR level of 36 patients. Discrepancies in the current information such as baseline data, biochemical examination, cardiac ultrasound data, etc., were examined to identify the underlying risk factors, and a multifactorial linear regression analysis of plaque properties was conducted. (3) Results: NLR = 2.64 was utilized to classify 18 patients into the L-NLR group and 18 patients into the H-NLR group. There were statistically significant differences in age, a pre-percutaneous coronary intervention (PCI) SYNTAX II score, a C-reactive protein (CRP), interleukin (IL)-6, plaque loading, a fibro-lipid tissue area, calcified nubs, and virtual histology-thin fibrous cap atherosclerotic (VH-TCFA). The significant impacts of variations in age, neutrophil-lymphocyte ratio (NLR) levels, and IL-6 levels on the plaque stress and percentage of the fibro-lipid tissue in virtual histology-intravascular ultrasound (VH-IVUS) were identified through multifactorial linear regression. (4) Conclusions: The high NLR group demonstrated increased myocardial injury severity, consistent with higher SYNTAX II scores, a higher plaque burden, and higher proportions of vulnerable components. NLR proved to be a risk factor for both the plaque load and the proportion of the fibro-lipid tissue in ISR.

What can be learned from real-world data about chronic spontaneous urticaria?

Background: Chronic spontaneous urticaria (CSU) is a common disease with complex pathogenesis. Patients' clinical characteristics and responses to treatment vary. Objective: We aimed to investigate the role of data obtained from routinely recommended tests in predicting the response to omalizumab, the only biologic agent approved for treatment, and in defining the clinical characteristics of the patients. Methods: A retrospective study of patients who started omalizumab treatment for CSU between 2015 and 2022 at the Department of Dermatology, Pamukkale University, was conducted. Response criteria were based on the urticaria control test, and patients with a urticaria control test score <12 at 6 months were considered treatment non-responders. Eosinophil and basophil counts, neutrophil-lymphocyte ratio (NLR), systemic immune inflammation index (SII), systemic inflammation response index (SIRI), and total immunoglobulin E (IgE) levels of the patients were evaluated before treatment and at the sixth month of treatment. Results: A total of 23.1% of the patients were unresponsive to omalizumab. The response rate to the omalizumab treatment of the patients with a total IgE level ≤ 30 IU/L (n = 4 [5.7%]) was significantly lower than patients with total IgE level > 30 IU/L (n = 66 [94.3%]) (p = 0.015). The mean ± standard deviation SIRI levels were significantly higher in non-responders versus responders (1.53 ± 1.03 versus 1.15 ± 7.76; p = 0.026). Eosinophil counts positively correlated with basophil counts (r = 587; p < 0.001) and IgE levels (r = 0.290; p = 0.005) but a negative correlation was found with levels of NLR (r = -0.475; p < 0.001), SIRI (r = -0.259; p = 0.013), and SII (r = -0.285; p = 0.006). NLR levels were lower in CSU patients with atopy, than in those without atopy (1.9 ± 0.9 vs 2.9 ± 2.1, p = 0.022). Conclusion: We suggest that eosinopenia and high NLR levels are linked to autoimmune CSU. Predicting a poor response to omalizumab seems possible with total IgE levels < 30 IU/L and high SIRI levels.

Preoperative and postoperative platelet-lymphocyte ratio as a prognostic marker for patients with soft tissue sarcoma treated with curative resection.

e23568 Background: In cancer development and progression, systemic inflammation has been implicated. Inflammatory markers have been identified as prognostic indicators in numerous malignancies. In this study, we explored the prognostic relevance of initial and postoperative systemic inflammatory markers (neutrophil -lymphocyte ratio, platelet -lymphocyte ratio) on relapse-free survival (RFS) and overall survival (OS) in patients with soft -tissue sarcoma (STS) who underwent curative resection. Methods: We included a total of 89 patients with STS who underwent extensive and radical resection at the Kyungpook National University Chilgok Hospital (Daegu, Korea,) between 2004 and 2018. Kaplan-Meier curves and RFS and OS were calculated using multivariate Cox proportional models. Results: The median age of the patients was 55 years (range 27 - 86) and the ratio of male-to-female ratio was approximately 1:1. A total of 67 (75.3%) patients demonstrated a high initial neutrophil-lymphocyte ratio(NLR) (≥4.1) and 65 (75.3%) showed a high initial platelet-lymphocyte ratio(PLR) (≥231). After curative resection, the number of patients with high NLR and PLR was 16(18.0%) and 17 (29.3%). In both the NLR and PLR groups, including the postoperative NLR and postoperative PLR subgroups, no significant differences were observed in terms of age, sex, histologic type, tumor site, tumor size, tumor depth, or American Joint Committee on Cancer staging when stratified into high and low subgroups. In the univariate and multivariate analyses, an elevated initial PLR ratio was significantly associated with a decreased RFS (hazard ratio[HR]: 2.120; 95% confidence interval[CI]: 1.021 - 4.883, p = 0.017) and OS (HR: 5.073; 95% CI: 1.731 - 14.87, p = 0.003). Patients with a high PLR (PLR &gt; 231) had a median RFS of 24 months, whereas those with a low PLR (PLR ≤231) had a median RFS of 96 months. The median OS was 50 and 298 months for the high PLR and low PLR groups, respectively. Furthermore, a high postoperative PLR ratio was significantly associated with a decreased RFS (HR: 3.921; 95% CI: 1.738 - 8.845, p = 0.001) and OS (HR: 5.702; 95% CI: 1.099 -29.576, p = 0.038). Conclusions: The present results suggest that the preoperative and postoperative PLR ratio can be used as a cost- effective prognostic marker for oncologic outcomes in patients with STS who underwent surgery.

Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio as an Early Prognostic Marker in Patients with Ovarian Cancer: A Systematic Review and Meta-Analysis.

Presently, ovarian cancer remains the leading cause of death in gynecological malignancies. The survival rate of these patients is low, which might be caused by early metastases and delayed diagnosis. Therefore, it is crucial to investigate novel practical markers that provide early prognostic value which helps construct individualized treatment. A thorough investigation of the neutrophil-lymphocyte ratio (NLR) and lymphocyte ratio (PLR) in ovarian cancer patients was conducted using article selection from PubMed, Cochrane, Science Direct, and Google Scholar databases. The outcomes and hazard ratio (HR) were obtained using Review Manager 5.4, and the 95% Confidence Interval (CI) result was calculated. The chief endpoints of interest in this study include overall survival (OS) and progression-free survival (PFS). Sixteen studies with 3,862 patients were included with a mean age of 50.6 years and a mean follow-up of 45.84 months. Multivariate studies demonstrated that a higher NLR is associated with worse PFS and OS, HR 1.35;95% CI [1.05-1.74] and HR 1.46; 95% CI [1.16-1.83] respectively. Similar results are observed with PLR and poorer PFS and OS, HR 1.62; 95% CI [1.09-2.43] and HR 1.66; 95% CI [1.12-2.46]. Pre-treatment PLR and NLR were found to be prognostic factors in determining PFS and OS in ovarian cancer. High values in pre-treatment PLR and NLR may indicate worse clinical outcomes.
