Objective: Inflamatory processes play an important role in the etiology of psychiatric disorders. The aim of this study was to evaluate inflammatory complete blood count (CBC) parameters in substance use disorder (SUD). Methods: The study included 90 patients with SUD and 90 healthy controls (HC). The Student t-test was used to compare CBC parameters between the groups. The Kruskal – Wallis test was used to compare the data on the basis of substance types. Results: Leukocyte, lymphocyte, and monocyte levels were higher in SUD group than HC. Leukocyte and neutrophil levels of patients with opioid use disorder (OUD) were higher than HC. Platelet levels and neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune inflammation index values were higher in patients with OUD than in patients with non-opioid substance use disorder (nOUD). Moreover, lymphocyte and monocyte levels were higher in patients with nOUD than in HC. Monocyte levels were increased in patients with cannabinoid use disorder compared to HC. Conclusion: The results suggested that inflammatory CBC parameters play an important role in the etiology of SUD according to type of substance. However, there is not enough data for supporting the clinical use of these parameters.. [ABSTRACT FROM AUTHOR]

Objective: The complete blood count (CBC) parameters and the ratios regarding these parameters have been demonstrated to be useful diagnostic biomarkers for many infectious diseases. Herein, we aimed to evaluate and compare the usefulness of the predictive role of the CBC in the differential diagnosis of pulmonary tuberculosis (TB) from community-acquired pneumonia (CAP) in children. We also compared serum electrolyte levels between the 2 diseases. Materials and Methods: In this retrospective study, we analyzed the efficacy of CBC parameters and neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), plateletto-lymphocyte ratio (PLR), neutrophil-to-monocyte-plus-lymphocyte ratio (NMLR), and serum electrolyte levels in the differential diagnosis of pulmonary TB from CAP in children. We also classified patients with TB into 2 groups according to the microbiologic confirmation. We investigated whether there is any difference regarding these parameters in patients with positive microbiologic results. Results: A total of 163 patients diagnosed with TB and CAP were included in this study. The WBC, neutrophil and monocyte counts, NLR, MLR, NMLR, mean platelet volume (MPV), and C-reactive protein (CRP) values were higher in CAP. There was statistical significance among serum sodium and phosphorus (P) levels between the 2 groups. Microbiologic confirmation was determined in 37 (35.5%) patients with the diagnosis of TB. The NLR, MLR, NMLR, CRP, and P values were significantly higher in patients with microbiologic confirmation. Conclusion: The results of the present study suggest that complete blood count parameters, NLR, MLR, NMLR, and CRP can be useful and cost-effective markers in differentiating pulmonary TB from CAP in the early stages of diagnosis.

Background: Hemoglobin, albumin, lymphocyte, and platelet (HALP) scores are easily calculable markers that allow the evaluation of systemic inflammation and nutritional status. This study aimed to evaluate and compare the predictive power of HALP scores for 3-month and 1-year mortality in patients admitted to the emergency department with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: Hospital records of patients aged > 18 years who had been diagnosed with AECOPD in the emergency department (ED) and hospitalized were retrospectively reviewed. The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and HALP scores of the patients were analyzed. Three month and 1-year mortality rates of the patients were evaluated. Results: Mean age of the 957 patients were 70.6 ± 10.2 and 66.9% (n = 660) were male. The 3-month and 1-year mortality rates were 21.2% and 30.0%, respectively. For 3-month and 1-year mortality, the NLR and PLR were significantly higher and the HALP score was significantly lower in the mortality groups, and the HALP score was found to be a good predictor of 3-month and 1-year mortality. Conclusion: HALP score is a potential prognostic index for patients with AECOPD. Increased NLR and PLR were associated with increased mortality in patients with AECOPD. The HALP score, NLR, and PLR can be used as important predictors of mortality in patients with AECOPD. [ABSTRACT FROM AUTHOR]

Objective: The pathophysiology of uterine scar dehiscence is not yet clear. The aim of this study was to investigate whether preoperative hemogram parameters can be used as predictive markers of uterine scar dehiscence, thus improving prediction and contributing to management of repeat Cesarean section. Material and Methods: Between 2015 and 2020, 36670 (47.6%) cesarean sections were delivered in our hospital and 16943 of them had a previous Cesarean section. All cases of uterine scar rupture detected during Cesarean section were identified, and a total of 40 patients were included after excluding cases with impairment of the systemic inflammatory response (SIR). Controls consisted of 40 randomly selected, ageand body mass index (BMI)-matched patients, and the groups were compared. Results: Age, BMI, and gravidity were similar (p>0.05). Although the gestational week and Apgar scores were similar between the groups (p>0.05), the birth weight amongst controls was significantly higher than the uterine dehiscence group (p=0.028). Platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, and other hemogram values were similar in both groups (p>0.05). Mean platelet volume (MPV) in the control group was significantly higher than in the uterine rupture group (p=0.049). Regression analysis found no significant result between hemogram parameters, birth weight, and dehiscence. Conclusion: In this study, which set out to identify predictors of the risk of uterine scar dehiscence with SIR parameters, only the MPV value was lower in the dehiscence group.

Objective: This study investigated whether serum amyloid A (AA) levels can be used as a biomarker in patients with threatened abortion. Material and Methods: This prospective cohort study was conducted at the Antalya Training and Research Hospital, Department of Obstetrics and Gynecology, Türkiye, between April and October 2023. Eighty‐eight pregnant women, 44 diagnosed with threatened miscarriage (Group 1) and 44 healthy individuals (Group 2), were included in the study. Sociodemographic, obstetric, and laboratory parameters were compared between the groups. Results: No statistically significant differences were observed between the groups in terms of sociodemographic data (age, body mass index, education level, economic status, occupation status, smoking, and alcohol consumption). However, obstetric characteristics (number of pregnancies, living children, miscarriages, dilatation and curettage, gestational age on admission, and fetal crown‐rump length) and laboratory values including complete blood count, hematocrit, leukocyte, neutrophil, lymphocytes, platelet, hs‐C‐reactive protein, neutrophil‐lymphocyte and platelet‐lymphocyte ratio (p >.05), and serum AA values (7.49 ± 3.07 in Group 1 vs. 9.46 ± 4.80 in Group 2, p =.024) differed significantly. Receiver operating characteristic analysis showed that the area under the curve (AUC: 0.662) was statistically significant for serum AA (p =.032), with a cut‐off value of ≥7.51 (95% [confidence interval] 0.516−0.749, sensitivity 65%, specificity 51%). The positive predictive value of serum AA for threatened miscarriage was 56.8%, and the negative predictive value 59.4%. Conclusion: This study shows that serum AA can be used as a biomarker in the diagnosis of threatened miscarriage. Prospective studies involving more participants are now needed to confirm our results. [ABSTRACT FROM AUTHOR]

Background/Aim: The severity and extent of ulcerative colitis (UC) guide us in determining the treatment method for each case. It has been suggested in the literature that high neutrophil-lymphocyte and platelet lymphocyte ratios can serve as markers of active ulcerative colitis. This study retrospectively analyzes the relationship between neutrophil-lymphocyte ratio and platelet-lymphocyte ratio with clinical activity indices and endoscopic activity indices in predicting disease severity in patients with ulcerative colitis. There are few studies in the literature regarding the relationship between platelet-lymphocyte ratio (PLR) and disease activation in ulcerative colitis. This study contributes to the follow-up and outcomes of these patients, as there is a lack of sufficient retrospective studies on the platelet/lymphocyte ratio in patients diagnosed with UC in our country and worldwide. Methods: This study is a population-based, single-center, case-controlled study. It was conducted by retrospectively analyzing the hospital information system for data recorded during the routine diagnosis and treatment of ulcerative colitis patients followed and treated at Celal Bayar University Medical Faculty Gastroenterology Division between January 2014 and December 2021. A total of 135 patients with ulcerative colitis were included in the study. The patients were divided into 2 groups, active disease and disease in remission, based on clinical activity indices and endoscopic activity indices. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hemoglobin (Hb), white blood cell (WBC), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) levels were checked during routine follow-up of patients with ulcerative colitis. These values were recorded at the first presentation to the hospital and 3 months after treatment. Results: Laboratory values at presentation were compared with those at the third month of treatment in a group of 113 patients with UC in remission: NLR (5.529 (3.485) and 4.374 (2.335), [P<0.001]), erythrocyte sedimentation rate (26.81 (20.42) and 21.78 (19.32), [P=0.015]), C-reactive protein (4.087 (6.729) and 1.696 (3.525), [P<0.001]), and white blood cell count (9,864 (3,514) and 8,067 (1,927), [P<0.001]) were found to be lower than the baseline values. As expected, decreases in inflammatory markers were observed in patients in remission. In a group of 22 patients with active disease, values at presentation were compared with those at the third month of treatment: neutrophil count (8,508 (2,908) and 9,646 (3,265), [P=0.037]) and platelet count (289,591 (95,123) and 323,364 (127,647), [P=0.010]) were found to be high. Similarly, ESR (19.63 (15.43) and 27.89 (21.11), [P=0.036]) was found to be high. These values were higher in active disease compared to the time of admission. Conclusion: In our study, neutrophil-lymphocyte ratios and platelet-lymphocyte ratios were significantly higher in patients with active ulcerative colitis. The level of inflammatory markers in ulcerative colitis patients at the time of diagnosis and in the early stages of the disease is helpful in predicting the course of the disease, and this was shown to be related to clinical, endoscopic, and laboratory indices. These inflammatory markers can predict disease activity alone or in combination. However, a threshold value could not be calculated due to the insufficient number of patients, and thus, more comprehensive prospective studies are needed. [ABSTRACT FROM AUTHOR]

Aim: Inflammation plays an important role in the development of diabetic nephropathy (DNP). In our study, we aimed to analyze the relationship between the mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), uric acid-lymphocyte ratio (UALR), and uric acid level with early diagnosis of DNP and DNP progression. Methods: Our cross-sectional study, which is a type of observational study, included patients diagnosed with type 2 diabetes mellitus and followed in the internal medicine and nephrology clinics of our hospital. Patients were divided into four groups: Group 1: estimated glomerular filtration rate (eGFR) >60 mL/min/1.73 m² and albuminuria <30 mcg/day; Group 2: eGFR >60 mL/min/1.73 m² and albuminuria: 30-300 mcg/day; Group 3: eGFR >60 mL/min/1.73 m² and albuminuria >300 mcg/day; and Group 4: eGFR <60 mL/ min/1.73 m² and albuminuria >300 mcg/day. Thirty-six patients were included in group 1, 38 patients in group 2, 35 patients in group 3, and 40 patients in group 4. Mean platelet volume, NLR, PLR, UALR, and uric acid levels were compared among the groups. Results: A total of 149 patients were included in the study; 57.7% were female, and the mean age was 55.2±9.2 years. Significant differences were found among the groups in terms of MPV, PLR, NLR, and UALR (p<0.001, p=0.023, p<0.001, p<0.001, respectively). There was a negative correlation between eGFR and MPV (r=-0.218, p=0.008). While there was no relationship between eGFR and platelet values, a relationship was obtained when platelets were compared with lymphocytes (r=-0.263, p=0.002). There was a weak relationship between eGFR and neutrophil levels (r=-0.188, p=0.026), but a stronger relationship was found when neutrophil and lymphocyte values were rationed (r=-0.414, p<0.001). Conclusion: Mean platelet volume, PLR, NLR, UALR, and uric acid levels, especially MPV, can be used in the development and progression of DNP. [ABSTRACT FROM AUTHOR]

Objectives: In this study, the relationship between response to second-line nivolumab treatment in advanced nonsmall cell lung cancer (NSCLC) and systemic immune inflammation index (SII) was investigated. Methods: One hundred and twenty-nine patients with advanced NSCLC who received nivolumab in second line between July 2018 and July 2023 were included. The optimum cutoff value for neutrophil/lymphocyte ratio (NLR), SII, platelet/lymphocyte ratio (PLR) and body mass index (BMI) was calculated. Progression free survival (PFS) and overall survival (OS) were evaluated. Univariate and multivariate analysis were performed for all parameters for prognostic evaluation. Results: In univariate analysis, patients with low SII found longer PFS and OS (HR = 1.762 for PFS, 95% CI 1.053-2.949, p=0.031, for OS HR=1.433, 95% CI 1.011-2.031, p=0.043). However, in multivariate analysis, no significance was found between low SII and OS (HR=1.614 for OS, 95%CI 0.984-2.648, p=0.058). No statistically significant relationship was found between NLR, PLR, BMI and Glasgow prognostic score (GPS) with OS and PFS. OS was found to be longer in patients with programmed cell death ligand 1 (PD-L1) of 1% and above and without liver metastasis (p=0.031 and p=0.040, respectively). Conclusion: Low SII before nivolumab treatment was associated with long PFS. A significant correlation was found between PD-L1 of 1% and above and OS. [ABSTRACT FROM AUTHOR]

Objectives: It was aimed to investigate the prognostic significance of neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), systemic immune-inflammation index(SII), and Combined LDH Albumine Score(CLAS) in metastatic non-small cell lung cancer(mNSCLC) patients receiving nivolumab. Methods: Sixty-five mNSCLC patients who received nivolumab as monotherapy and had a follow-up file in Kocaeli City Hospital were analyzed retrospectively. ROC-curve analysis and median values were used to determine the cut-off. The relationship between overall survival(OS), progression-free survival(PFS) and clinical and laboratory parameters was evaluated by multivariate analyses. Results: Mean age was 62.5±4.5 years, more than half(66%) had denovo metastatic disease. Median follow-up time was 22 (IQR:12-33), median PFS was 6 (95% CI 3.4-8.6), and median OS was 9 (95% CI 5.2-18.1) months. NLR=3.2, PLR=199, and SII=776 were considered as elevated levels. No factor other than NLR could be identified as having an impact on PFS (p=0.015, [HR]:0.46,95%CI: 0.23-0.91). Univariate analyses showed that high baseline NLR, low baseline albumin and CLAS< 2 (0-1) were a significant risk factors for poor OS, but only CLAS<2 was found as an independent prognostic factor for OS in multivariate analyses (p=0.013, [HR]:0.68,95%CI:0.42-0,95). Conclusion: NLR and CLAS were predictive for survival in patients with NSCLC receiving nivolumab. This is the second study on CLAS in the literature. [ABSTRACT FROM AUTHOR]

Objective: Neutrophil, lymphocyte, monocyte, thrombocyte counts and as novel inflammatory factors, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and red cell distribution width (RDW) play an important role in the occurrence and development of diseases. In this study, it was aimed to investigate the relationship between preoperative NLR, PLR, LMR and RDW values of patients hospitalized in the intensive care unit (ICU) after oncological surgery, and the length of intensive care and mortality rates. In addition, it was aimed to compare the demographic, clinical characteristics and laboratory parameters of the patients between both groups. Methods: Patients hospitalized in the ICU after oncological surgery were included in the study. The patients were divided into two groups as patients undergoing gastrointestinal malignancy (colorectal, stomach and hepatocellular) surgery (group 1) and patients who had undergoing urologic malignancy (kidney, bladder and prostate) surgery (group 2). Information regarding demographics (age and gender), comorbidities, neutrophil-lymphocyte-platelet counts, NLR-PLR-LMR-RDW values, length of ICU stay, acute physiology and chronic health evaluation II (APACHE-II) score, Glasgow coma scale and mortality rates were recorded. Results: Two hundred sixty-eight patients were analyzed including 144 patients (99 women, 45 men) undergoing gastrointestinal malignancy surgery (group 1), 124 patients (28 women, 96 men) undergoing urologic malignancy surgery (group 2). We found differences in lymphocyte count, LMR, and PLR values between the two groups. We found that NLR, PLR, LMR, and RDW values, as well as the counts of neutrophils, lymphocytes, and platelets, can predict mortality at specific cut-off points. Furthermore, we also identified an association between NLR, PLR, RDW values, and the APACHE-II score with the length of ICU stay. There was a difference in lymphocyte count, LMR and PLR values between the two groups. Conclusion: By utilizing cost-effective and practically applicable laboratory parameters, we can anticipate the mortality rates of patients following after cancer surgery. Patients predicted to have a high mortality rate can be followed more closely and comprehensively. [ABSTRACT FROM AUTHOR]

INTRODUCTION: This study aims to evaluate the prognostic value of the platelet-to-lymphocyte ratio in determining the severity and mortality of adults hospitalized for COVID-19 using retrospective data and a meta-analysis of previous studies on the platelet-to-lymphocyte ratio worldwide. MATERIAL AND METHODS: A retrospective study was conducted at the Kırdar City Hospital (Istanbul, Turkey) and included 521 COVID-19 patients. A systematic literature search of EMBASE, MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar databases was performed for relevant trials relating to the PLR ratio in COVID-19 published before April 12, 2023. RESULTS: In the retrospective part of the study, PLR values were found to predict COVID-19 severity at admission with an AUC of 0.61 (SE = 0.03; 95% CI: 0.56 to 0.65; p = 0.0003) as well as survival status in a statistically significant fashion with an AUC of 0.59 (SE = 0.03; 95% CI: 0.55 to 0.64; p = 0.0004). Results of our meta-analysis showed a significant relationship between PLR and COVID-19 severity, with a pooled standardized mean difference (SMD) of 1.34 (95% CI: 1.13 to 1.55; p < 0 .001), and that PLR was significantly lower among patients who survived compared to deceased patients (SMD = -1.32; 95% CI: 1.57 to -1.07; p < 0.001). CONCLUSIONS: PLR is a valid, readily available marker that can distinguish COVID-19 individuals with distinct progression and survival outcomes. [ABSTRACT FROM AUTHOR]

Background: Covid-19 has undergone many mutations over time. The most prominent variants have been the Alpha, Beta, Delta, Gamma, and finally, the Omicron variants. This study aims to determine the availability of neutrophil/lymphocyte rate (NLR), platelet/lymphocyte rate (PLR) and Systemic Inflammatory Index (SII), prognostic and diagnostic significance, in the differentiation of variants in pediatric Covid-19 patients. Materials and Methods: In this retrospective study, 141 pediatric patients who were found to be positive for Covid-19 in Harran University Medical Faculty Hospital between January 2021 and April 2022 were included. A control group was formed from 107 healthy children selected from among those who applied to the general pediatric outpatient clinic for routine health evaluations. Results: When the age distribution of the patients was examined, the median was 7.0 (0.1-18) years. When the variants were compared, there was a significant difference between lymphocyte values, while leukocyte, neutrophil, C-reactive protein (CRP) and Mean Platelet Volume (MPV) did not change significantly. At the same time, there was a statistically significant difference between NLR, PLR and SII variants in Covid-19 positive patients (p<0.05); It was found that CRP, CRP/albumin rate (CAR), and MPV values did not change significantly between variants (p>0.05). It was observed that the NLR, PLR and SII delta variants increased significantly compared to the omicron variant (p<0.05). CRP and CAR were significantly increased in the severe clinical course compared to the asymptomatic group (p<0.05). Conclusions: In our study, it was seen that patients with delta variant had higher NLR, PLR and SII values compared to omicron variant when viewed from the point of view of Covid-19 variants. Therefore, we think that during the diagnosis of Covid-19 accompanied by these parameters, variant analysis can be performed, especially in terms of the delta variant, and it will shed light on the differential diagnosis, appropriate treatment, and measures to be taken by early and simple means.

Objective: This study aims to analyze previously suggested hematological markers in addition to the systemic inflammation response index (SIRI) and the aggregate index of systemic inflammation (AISI) in patients with Bell’s palsy (BP) and to identify the most important hematologic inflammatory marker among them. Material and Methods: The study consisted of 87 patients with BP who were between the ages of 18 and 65. Sixty-three healthy controls with similar age and sex distribution were assembled. A retrospective examination was done on the patient and control group files. House Brackmann grading system stage at the admission of patients with BP was recorded. Routine complete blood count values obtained from the patients at the time of admission and before the start of treatment were recorded. The systemic immune-inflammatory index (SII), the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the monocyte-to-lymphocyte ratio (MLR), SIRI, and AISI were all generated from these values. Results: There were 39 (44.8%) men, 48 (55.2%) women in the BP group, and 34 (54.0%) men and 29 (46.0%) women in the control group. The patient group had substantially increased neutrophil, white blood cell, NLR, PLR, SII, SIRI, and AISI levels (P values: 0.001, 0.001, 0.001, 0.033, 0.001, 0.001, and 0.001, respectively). NLR, PLR, SII, SIRI, and AISI values were lower in Receiver Operating Characteristics curves (ROC) analysis than neutrophil the areas under the curves (AUC) values. Conclusion: Neutrophil count was found to be more valuable than other inflammatory indexes in the diagnosis of BP. [ABSTRACT FROM AUTHOR]

Background/Aim: Pressure ulcers (PU) pose a significant problem for patients in intensive care. Various factors contribute to the development of pressure sores. The primary focus of treatment is to implement measures that prevent factors such as nutrition and positioning, which can lead to PUs. Therefore, it is crucial to identify parameters that can serve as warning signals for the formation and progression of PU. This study investigates the potential use of hematological parameters as warning signals. Methods: Demographic data, co-morbidities, PU stages, and laboratory parameters of 158 patients hospitalized in the intensive care unit who developed pressure ulcers during their hospital stay were recorded and analyzed. Results: Among the 158 cases included in the study, PUs were more prevalent in patients of advanced age, those with pneumonia, chronic obstructive pulmonary disease (COPD), coronary diseases, and neurodegenerative diseases. Mean platelet volume (MPV) was significantly higher in PU stages 2 and 3 compared to stage 1. However, age, lymphocyte count, monocyte count, neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) did not exhibit significant differences among the stages of PU (P<0.05). Conclusion: Advanced age, pneumonia, COPD, coronary diseases, and neurodegenerative diseases are identified as risk factors for PU. Although MPV was initially considered a potential, stimulating parameter, the evidence was insufficient. Further research is required to explore this issue. The impact of parameters other than MPV did not show any excitatory signal in this study. [ABSTRACT FROM AUTHOR]

Background: The hospital outcomes and predictors of acute peripancreatic fluid collection (APFC) have not been well-characterized. In this study, we aimed to investigate the clinical outcomes of APFC in patients with acute pancreatitis (AP) and the role of the systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and C-reactive protein (CRP) level in predicting the occurrence of APFC. Methods: In this retrospective study, the complicated group (patients with APFC) and the uncomplicated group (patients without APFC) were compared for their clinical characteristics, hospital outcomes (mortality rate, intensive care unit admission rate, and length of hospital stay), pseudocyst formation, CRP levels, SII, and SIRI on admission and at 48 hours. Results: Of 132 patients with AP, 51 (38.6%) had APFC and eight (6.1%) had pancreatic pseudocysts. Of 51 patients with APFC, 15.7% had pancreatic pseudocysts. Pseudocyst did not develop in the uncomplicated group. SII value at 48 h [median 859 (541-1740) x 109/L vs. 610 (343-1259) x 109/L, P = 0.01] and CRP level at 48 h [89 (40-237) mg/L vs. 38 (12-122) mg/L, P = 0.01] were higher in the complicated group than in the uncomplicated group. The length of hospital stay was longer in the complicated group, compared with the uncomplicated group [median 8 days (5-15), vs. 4 days (3-7), P < 0.001, respectively]. No significant difference was detected between the two study groups' mortality rates and intensive care unit admission rates. Conclusions: While 38.6% of the AP patients had APFC, 6.1% of all patients and 15.7% of the patients with APFC had pancreatic pseudocysts. APFC was found to lengthen the hospital stay and to be associated with the SII value and CRP level measured at 48 h. [ABSTRACT FROM AUTHOR]

Background/Aim: Type 2 diabetes mellitus (T2DM) is a common chronic disease with an increasing incidence worldwide and its effects are being seen in many countries. Insulin resistance is the main factor in the pathophysiology. T2DM leads to an increase in mortality and morbidity due to macrovascular and microvascular complications. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are effective parameters in monitoring the inflammatory response. The primary aim of this study was to investigate glycemic control in patients with type 2 diabetes by focusing on their correlation with inflammatory markers, such as NLR and PLR, glycated hemoglobin (HbA1c), and fasting blood glucose levels. Methods: The present study was carried out in 2022 within the purview of the Internal Medicine Clinic at Balikesir İvrindi State Hospital. Data from the initial annual consultations of patients with T2DM, either newly diagnosed or previously diagnosed and visiting for follow-up, were utilized. Our study excluded patients under the age of 18 and those diagnosed with cirrhosis, heart failure, type 1 diabetes mellitus, malignancy, epilepsy, acute infection, pregnancy, or chronic inflammatory disease. We further excluded those on medications including steroids, antivirals, anticonvulsants, antipsychotics, antithyroids, and chemotherapeutic drugs that impact the leukocyte count. Based on their HbA1c levels, patients were systematically categorized into two distinct cohorts: those with controlled blood sugar (HbA1c =7%) and those with uncontrolled blood sugar (HbA1c >7%). In the ambit of this study, we incorporated data from 205 patients. We employed a cross-sectional study that retrospectively examined the correlation between NLR, PLR, and glycemic regulation in T2DM patients. SPSS 22.0 software was used to perform statistical calculations. Results: It was observed that patients with poor glycemic control had longer disease durations and this disparity bore statistical significance (P=0.005). Patients exhibiting poor glycemic control demonstrated elevated levels of CRP (C-reactive protein), a difference that reached statistical significance (P=0.003). The group exhibiting poor glycemic control demonstrated a notable elevation in NLR, indicating statistical significance (P=0.001). Although it was not statistically significant, PLR was found to be higher in patients with uncontrolled T2DM (P=0.441). Conclusion: This research investigates the correlation between HbA1c levels and inflammatory markers, specifically NLR and TLR, in T2DM patients who exhibit poor control of glycemia. Our findings highlight the potential of these markers as indicators of glycemic control, thus emphasizing the need for integrated strategies for managing inflammation and improving glycemic control in T2DM patients. The novelty of this area of research contributes to the scarcity of available literature, underlining the importance and timeliness of this study. Based on our findings, we suggest an increased focus on regular monitoring of inflammatory markers, for instance NLR and PLR, to assess the glycemic control in T2DM patients. The significant correlation of these markers with HbA1c levels implies that they could potentially serve as useful tools in personalizing diabetes management strategies, leading to improved patient outcomes. Not only does our research contribute to filling this knowledge gap, but it also underscores the potential for utilizing inflammatory markers in tracking disease progression and optimizing treatment efficacy in T2DM.

Introduction: In this study, we aimed to explore using the predictive role of systemic immune inflammation index (SII) for responses of intravesical Bacillus Calmette-Guérin (BCG) therapy in patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). Methods: From 9 centers, we reviewed the data of patients treated for intermediate- and high-risk NMIBC between 2011 and 2021. All patients enrolled in the study presented with T1 and/or high-grade tumors on initial TURB had undergone re-TURB within 4–6 weeks after initial TURB and had received at least a 6-week course of intravesical BCG induction. SII was calculated with the formula SII = (P × N)/L, where P, N, and L refer to peripheral platelet, neutrophil, and lymphocyte counts, respectively. In patients with intermediate- and high-risk NMIBC, the clinicopathological features and follow-up data were evaluated to compare SII with other systemic inflammation-based prognostic indices. These included the neutrophil-to-lymphocyte ratio (NLR), platelet-to-neutrophil ratio (PNR), and platelet-to-lymphocyte ratio (PLR). Results: A total of 269 patients were enrolled in the study. Median follow-up time was 39 months. Disease recurrence and progression were observed in 71 (26.4%) and 19 (7.1%) patients, respectively. For groups with and without disease recurrence in terms of NLR, PLR, PNR, and SII calculated prior to intravesical BCG treatment, no statistically significant differences were observed (p = 0.470, p = 0.247, p = 0.495, and p = 0.243, respectively). Moreover, there were also no statistically significant differences between the groups with and without disease progression in terms of NLR, PLR, PNR, and SII (p = 0.504, p = 0.165, p = 0.410, and p = 0.242, respectively). SII did not show any statistically significant difference between early (<6 months) and late (≥6 months) recurrence (p = 0.492) and progression groups (p = 0.216). Conclusion: For patients with intermediate- and high-risk NMIBC, serum SII levels do not present as an appropriate biomarker for the prediction of disease recurrence and progression following intravesical BCG therapy. A possible explanation for the failure of SII to predict BCG response may be found in the impact of Turkey's nationwide tuberculosis vaccination program. [ABSTRACT FROM AUTHOR]

Background/Aim: Sarcoidosis is a multisystem inflammatory disease characterized by the infiltration of various organs. Due to the lack of a widely-accepted biomarker, researchers have explored alternative and previously unexplored parameters in sarcoidosis. This study aimed to investigate the utility of various markers, including the systemic immune-inflammation index (SII) and pan-immune-inflammation value (PIV), in patients with sarcoidosis. Methods: A case-control study was conducted between January 2019 and February 2023. The study included 75 patients diagnosed with sarcoidosis, and 93 healthy individuals matched for age, sex, and body mass index. Sarcoidosis-related features, such as lung stage and extrapulmonary involvement, were recorded. The researchers investigated SII, PIV, procalcitonin, erythrocyte sedimentation rate (ESR), Creactive protein (CRP), other biochemical results, and complete blood counts (including neutrophil, lymphocyte, monocyte, platelet counts, hemoglobin, mean platelet volume [MPV], and red cell distribution width [RDW]). Results: The age and sex distribution were similar in both the case and control groups (P=0.258 and P=0.196, respectively). The patient group had a significantly lower absolute lymphocyte count than the control group (P=0.035). Patients' RDW (P=0.007), platelet-to-lymphocyte ratio (P=0.028), and ESR (P<0.001) values were significantly higher compared to controls. No significant difference was observed between the two groups regarding other variables, including PIV and SII. There was a significant weak positive correlation between PIV and lung stage, as well as between MPV and the presence of erythema nodosum. Conclusion: PIV and SII values in patients with sarcoidosis were similar to controls. The positive correlations between PIV and lung stage and between MPV and erythema nodosum suggest potential relationships with sarcoidosis-related features and demonstrate the value of these readily available and inexpensive markers in patient management. Comprehensive studies are needed to clarify whether SII and/or PIV can be used to assess the characteristics of patients with sarcoidosis. [ABSTRACT FROM AUTHOR]

Background/Aim: Inflammation is a crucial component in the pathophysiology of systemic lupus erythematosus (SLE) nephritis. Immune-based scores, such as the neutrophil-lymphocyte and the plateletlymphocyte ratios (NLR and PLR, respectively) have been suggested as predictors of inflammation and prognosis in SLE. This study aimed to investigate the value of the systemic immune-inflammation index (SII), inflammatory prognostic index (IPI), and systemic inflammatory response index (SIRI) in SLE and lupus nephritis (LN). Methods: This case-control study consisted of 108 newly diagnosed SLE patients (separated into two subgroups, which included 34 patients with biopsy-proven LN and 74 without nephritis) and 108 age- and gender-matched healthy controls who presented to our outpatient clinic between October 2015 and June 2020. Patients with malignancy, lymphoproliferative and hematologic disorders, active infection, and autoimmune diseases other than SLE were excluded. Inflammation-based biomarkers were calculated at the first presentation of the disease and before any medication was administered. SII was calculated as Neutrophil/Lymphocyte x Platelet, SIRI as Neutrophil x Monocyte/Lymphocyte, and IPI as CRP x NLR/serum albumin. The Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) was used to measure disease activity. The capability of SII, SIRI, NLR, PLR, and IPI to distinguish between SLE patients with or without nephritis was assessed using receiver operating characteristic (ROC) curves. Correlations of inflammation-based scores (SII, SIRI, IPI, NLR) with disease activity and laboratory data of SLE patients were analyzed. Results: SII, SIRI, and IPI were significantly higher in SLE patients than in healthy controls (P=0.003, P=0.019, and P<0.001, respectively) and also significantly higher in patients with nephritis than in those without (P<0.001, P=0.009, and P=0.007, respectively). The area under the curve (AUC) for SII, SIRI, and IPI in terms of differentiating SLE patients with or without nephritis was 0.748, 0.690, and 0.663, respectively. The cut-off value of SII, SIRI, and IPI to predict LN was 552.25 (sensitivity: 64.7%; specificity: 64.9%; P<0.001), 1.08 (sensitivity: 61.8%; specificity: 62.2%; P=0.002), and 4.48 (sensitivity: 61.8%; specificity, 62.2%; P=0.007), respectively. Conclusion: SII, SIRI, and IPI may be valuable and promising inflammation-based biomarkers in SLE and for the presence of nephritis in SLE patients. SII was found to be the most reliable predictor of SLE among the inflammation-based biomarkers in our study. [ABSTRACT FROM AUTHOR]

Objective: The distribution of sensitization to inhalant allergens differs in every region of Turkey. This study aimed to determine the sensitization rates of common inhalant allergens in adult allergic rhinitis (AR) patients with/without asthma in Batman. Materials and Methods: A total number of 260 AR patients with or without asthma who presented to the outpatient clinic of Adult Immunology and Allergy between April 2021 and May 2022 were retrospectively evaluated. The demographic, clinical and laboratory features such as skin prick test (SPT) results, eosinophil counts (n/mm3), basophil counts (n/mm3), Neutrophil/Lymphocyte ratio (NLR), Platelet/Lymphocyte ratio (PLR), total Ig-E and specific Ig-E levels were analyzed. The parameters were compared between the subjects who have mild and moderate/severe AR. Results: The mean age was 31.9±9.7 years and more than half (62.5%) were female. When assessed separately, the most common inhalant allergens were Dermatophagoides (D.) farinae (n=128, 49.2%), Grass mix (n=119, 45.8%), Grass-cereal mix (n=112, 43.1%), D. pteronyssinus (n=94, 36.2%), Cockroach (n=77, 29.6%), Weed mix (n=57, 21.9%) and Aspergillus fumigatus (n=35, 13.5%), respectively. Additionally, the most common tree pollen allergen was Olive tree pollen (n=26, 10%), and the frequency of sensitization to Olive tree pollen was higher in moderate/severe (n=215, 82.7%) AR patients than in mild (n=45, 17.3%) ones (p=0.039). Conclusion: This study demonstrated that pollen sensitization was the most commonly detected one when the sensitizations were assessed in general, and it was followed by house dust mite, cockroach, animal epithelium and mold sensitizations. Also, Olive tree pollen was the most common tree pollen allergen in Batman. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to investigate the association between the platelet/lymphocyte ratio (PLR) and the neutrophil/lymphocyte ratio (NLR) and postoperative atrial fibrillation (POAF) after lung resection. Methods: After the implementation of the exclusion criteria, 170 patients were retrospectively analyzed. PLR and NLR were obtained from fasting complete blood counts before surgery. POAF was diagnosed using standard clinical criteria. The associations between different variables and POAF, NLR, and PLR were calculated using univariate and multivariate analyses. The receiver operating characteristics (ROC) curve was used to determine the sensitivity and specificity of PLR and NLR. Results: Of the 170 patients, 32 with POAF (mean age =71.28±7.27 y, 28 males and 4 females) and 138 patients without POAF (mean age =64.69±10.31 y, 125 males and 13 females) were identified, and the difference in the mean age was statistically significant (P=0.001). It was found that PLR (157.67±65.04 vs 127.52±56.80; P=0.005) and NLR (3.90±1.79 vs 2.04±0.88; P=0.001) were statistically significantly higher in the POAF group. In the multivariate regression analysis, age, lung resection size, chronic obstructive pulmonary disease, NLR, PLR, and pulmonary arterial pressure were independent risk factors. In the ROC analysis, PLR had a sensitivity of 100% and a specificity of 33% (AUC, 0.66; P<0.001), and NLR had a sensitivity of 71.9% and a specificity of 87.7% (AUC, 0.87; P<0.001). A comparison of AUC between PLR and NLR showed that NLR was statistically more significant (P<0.001). Conclusion: This study showed that NLR was a stronger independent risk factor than PLR for the development of POAF after lung resection. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to predict the RAS mutation by using imaging techniques and routine clinical or laboratory findings without tissue samples. Methods: The study was conducted in a retrospective cross-sectional plan in a tertiary-care health center between January 2010 and December 2016. Data collection was done from the patient files using the hospital's electronic patient registry. The primary outcome variable was the presence of RAS mutations as evaluated from the primary surgical specimens. Besides, data was collected on blood count parameters, serum CEA, and CA 19-9 levels. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) were calculated. Forty-five patients who underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) with pathologically confirmed metastatic colorectal adenocarcinoma were included in the study. Results: In our study the presence of RAS mutation was 40%(n=18). When the findings were compared according to the presence of RAS mutation, a statistically significant difference was found only in age at diagnosis (p=0.038). TLG (Total Lesion Glycolysis) significantly correlated with all other variables and age at diagnosis (p<0.05). A logistic regression model with age at diagnosis and TLG as explanatory variables had a sensitivity of 70.6% and a specificity of 81.5% in detecting RAS mutation. Conclusion: Although data on TLG and RAS mutations are valuable, they should be supported by studies with a larger cohort. [ABSTRACT FROM AUTHOR]

Background: It was aimed to investigate the effects of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and mean platelet volume (MPV) on mortality in cases of acute type A aortic dissection in this study. Materials and Methods: The files of patients who were operated on with the diagnosis of acute type A aortic dissection in Adıyaman Training and Research Hospital between January 2013 and November 2020 were reviewed retrospectively. The patients were divided into those who were discharged (Group I) and those who resulted in death (Group II). Demographic data, preoperative blood tests, operation times and mortality status of the patients were recorded. MPV, NLR and PLR were calculated and recorded in blood samples taken preoperatively. The obtained data were compared between groups and the relationship of the data with mortality was examined. Results: 23 of the patients in the study were male and 9 were female. While 22 of the patients were discharged with cure, 10 patients resulted in mortality. A significant difference was found in the exit group in terms of EF, CRP and cardiopulmonary bypass times (p<0.05). MPV, NLR and PLR were found to be higher in patients who resulted in death. However, this difference was not statistically significant (p>0.05). Conclusions: MPV, NLR and PLR could not be shown to have an effect on predicting mortality in acute type A aortic dissection.

Aim: The aim of this study was to investigate whether preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have a predictive value in short-term mortality in patients with operable colorectal cancer (CRC). Material and Methods: A total of 231 (93 female, 138 male) patients with operated CRC between 2016 and 2021 in a university hospital were analyzed retrospectively. Median age was 68 (range, 26-92) years and patients had been under follow-up for a median of 25 (range, 0-54) months. Patients were grouped with respect to survival, those who were alive (n=175) and those who died (n=56) during the follow-up. Results: The area under the curve for NLR was 0.649 (95% CI: 0.563-0.734, p=0.001), optimal cut-off was 5.08 and demonstrated a sensitivity of 48.2% and a specificity of 81.7% for predicting mortality. The area under the curve for PLR was 0.635 (95% CI: 0.546-0.723, p=0.002), optimal cut-off was 221.5 and demonstrated a sensitivity of 55.4% and a specificity of 72.0%. Multiple regression analysis revealed that recurrence (OR: 60.910, 95% CI: 9.807-378.319, p=<0.001), leakage (OR: 10.724, 95% CI: 1.281-89.747, p=0.029), high NLR (OR: 3.735, 95% CI: 1.602-8.711, p=0.002) and higher age (OR: 1.136, 95% CI: 1.081-1.193, p<0.001) were independently associated with mortality. Conclusion: The results of this study support studies indicating that preoperative NLR and PLR are effective in predicting short-term mortality in CRC patients who underwent surgical resection. Although further studies are necessary, these biomarkers are promising for future use as prognostic tools in CRC patients. [ABSTRACT FROM AUTHOR]

Aim: In this study, the roles of biomarkers from a peripheral blood sample in the diagnosis of COVID-19 patients who have visited the emergency room have been evaluated. Materials & methods: Peripheral blood parameters, systemic inflammatory index (SII), neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio were compared in patients with and without confirmed COVID-19 infection. Results: Comparisons made according to real-time PCR test results revealed that while no statistically significant difference was observed between test groups (negative-positive) regarding lymphocyte and platelet lymphocyte ratio values (p > 0.05), a statistically significant difference (p < 0.05) was found between the test groups regarding platelet, hemoglobin, leukocyte, neutrophil, NLR and SII values. Conclusion: Leukocyte, neutrophil, platelet count, NLR and SII values can be used in the diagnosis of COVID-19.
