O21 PLATELET COUNT-TO-PLATELET DISTRIBUTION WIDTH RATIO AND OTHER PLATELET INDICES AS COST-EFFECTIVE MARKERS OF PREECLAMPSIA: A CASE CONTROL STUDY

Background and objective: Platelet indices, like platelet count (PC), plateletcrit, mean platelet volume (MPV) and platelet distribution width (PDW), and their ratios have shown to be cost-effective and better predictors of preeclampsia (PE). However, PC/PDW ratio was not studied. Thus, this study aimed to compare platelet indices and their ratios between pregnant women with and without PE. Methods: An analytical, comparative, case-control study. Two groups were compared; pregnant women with PE (case, n=24) and without PE (control, n=72). The differences between cases and controls were compared using Student's t-test and Mann–Whitney U-test for continuous variables and chi-square tests and Fisher's exact test for categorical. Multivariable linear regression analysis for hematological parameters was performed to assess the effect of gestational age. Logistic regression was performed to calculate the odds ratio. Receiver operating characteristic curve was used to determine sensitivity, specificity and cutoff values. P < 0.05 was considered significant. Results: There was significant reduction in values of PC (p=0.004), plateletcrit (p=0.012), PC/MPV ratio (p=0.002), and PC/PDW (p= <0.001) among the pregnant women with PE compared to the control study group, while a significant increase was noticed in the values of PDW (p= <0.001) and MPV (p=0.021). PC/PDW had the highest area under the curve (AUC) of 0.767, followed by PDW (AUC=0.752). At the cutoff value of 15.1 (p<0.001) for PC/PDW, sensitivity was 70.8%, and specificity was 81.9%. The odds of diagnosing true positive cases of PE was 11.02 (95% CI =3.79-31.99, p=<0.001) times higher compared to values below it at this cutoff point. Conclusions: Present study suggests that platelet indices are economical tests that can act as indicators of risk of PE. Among all the parameters, PC/PDW has the highest sensitivity and specificity in the detection of PE at the cutoff of 15.1 and has emerged as a better predictor of PE.

The Importance of Preoperative NLR, PLR, and MPV Values in Predicting the Risk of Complications in Colorectal Peritoneal Carcinomatosis.

Colorectal cancer peritoneal carcinomatosis (CRC PC) necessitates preoperative assessment of inflammatory markers to predict postoperative outcomes and guide treatment. This study aims to evaluate the prognostic value of preoperative Neutrophil-Lymphocyte Ratio (NLR), Platelet-Lymphocyte Ratio (PLR), and Mean Platelet Volume (MPV) in predicting complications for CRC PC patients undergoing surgery. Calculating NLR, PLR, and MPV from patient data: NLR = absolute neutrophil count/total lymphocyte count, PLR = total lymphocyte count/total platelet count × 100, and MPV = platelet crit (PCT)/total platelet count. The study included 196 CRC PC patients and found significant relationships between these markers and overall survival (OS). Patients with an NLR of 3.77 had a median OS of 22.1 months, compared to 58.3 months for those with lower NLR (HR 2.7, 95% CI 1.1-5.3, p < 0.001). For CRC PC patients undergoing CRS+HIPEC, preoperative assessment of NLR, PLR, and MPV can serve as independent prognostic markers for OS. Incorporating these markers into preoperative evaluations may improve patient selection and outcome prediction.

Effect of adalimumab treatment on inflammatory and hematological parameters in patients with Hidradenitis suppurativa

Objective Hidradenitis suppurativa (HS), a chronic inflammatory disease that typically manifests after puberty, is characterised by painful nodules, abscesses, draining sinus tracts, and scars in areas rich in apocrine glands such as the axillary and inguinal regions. In recent years, blood-based biomarkers such as the Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR), Monocyte/Lymphocyte Ratio (MLR), Mean Platelet Volume (MPV), Systemic Immune-Inflammation Index (SII) and Pan-Immune-Inflammation Value (PIV) have been used as significant indicators of systemic inflammation. While there are few studies evaluating these biomarkers in HS, the response of these markers to treatment has only been assessed in one study to date. Our study aims to investigate the effect of adalimumab treatment on blood-based systemic inflammation biomarkers in HS, where inflammation plays a significant role. Methods The study included 42 adult patients who received adalimumab treatment at our dermatology and venereology clinic between January 2020 and January 2023. Medical records for complete blood count results of the patients were retrospectively reviewed. All systemic inflammation-based biomarkers were calculated from the absolute values of the complete blood count. The SII was calculated with the following formula: (neutrophil count × platelet count/lymphocyte count). The PIV was calculated as follows: (neutrophil count × platelet count × monocyte count/lymphocyte count). Values before the treatment and at the 12th week of treatment were compared. Results When the changes in the inflammatory parameters of the patients were examined, it was found that NLR (2.13 ± 0.87 vs 2.26 ± 1.12), PLR (111.01 ± 39.89 vs 99.43 ± 35.34), MLR (0.27 ± 0.11 vs 0.28 ± 0.12), MPV (9.59 ± 0.71 vs 9.70 ± 0.79), SII (680.79 ± 330.18 vs 687.89 ± 442.66), and PIV (552.02 ± 330.71 vs 605.05 ± 415.96) values did not change statistically significantly after treatment (p > 0.05). While there was a significant decrease in platelet count compared to before treatment, no statistically significant difference was found in the other evaluated blood cells. Conclusion Adalimumab treatment has not had a significant effect on systemic inflammation markers in HS, an inflammatory disease. More studies are needed to evaluate the effect of adalimumab on these markers in HS.

EVALUATION OF MEAN PLATELET VOLUME AND 25 HYDROXY VITAMIN D LEVELS IN GESTATIONAL DIABETIC WOMEN

Aim: According to few studies which tried to evaluate mean platelet volume (MPV) and 25 hydroxy vitamin D, have shown conflicting results in gestational diabetic patients. In this study we aimed to compare main platelet volume and 25 hydroxy vitamin D values between gestational diabetic patients and healty individual pregnant womens. Material and method: The patients were selected from 24-28 weeks pregnant people who made gestational diabetes screening and oral glucose tolerance test from obstetric-gynecology, diabetes and endocrinology polyclinics of Okmeydanı Training and Research Hospital. After the searching 52 gestational diabetic patients and 52 healty pregnant women included to the study. We estimated MPV and vitamin D level. In addition, demographic and clinical data of subjects were recorded. Results: Mean platelet volume (MPV) value was found 8,5 ± 1,0 fl and 8,3 ± 1,1 fl. in gestational diabetic and control group respectively. There was no statistically significant differences in MPV value between case and the control group (p&gt;0.05). Mean 25 hydroxy vitamin D value was found 20.5 ± 11.0 ng/ml and 21,1 ± 9,3 ng/ml. gestational diabetic and control group respectively. There was no statistically significant differences in 25 hydroxy (OH) vitamin D value between case and control group. Conclusion: In our study we found no statistically significant differences in MPV and 25-OH vitamin D values between gastational diabetic pregnant group and healty pregnant group.

The prognostic value of mean platelet volume in patients with coronary artery disease: An updated systematic review with meta-analyses.

Mean platelet volume (MPV) is a widely available laboratory index, however its prognostic significance in patients with coronary artery disease (CAD) is still unclear. We intended to investigate and pool the evidence on the prognostic utility of admission MPV in predicting clinical outcomes in patients with CAD. PubMed, Web of Science, and Scopus were the major databases used for literature search. The risk of bias was assessed using the quality in prognostic factor studies. We used random-effects pairwise analysis with the Knapp and Hartung approach supported further with permutation tests and prediction intervals (PIs). We identified 52 studies with 47,066 patients. A meta-analysis of nine studies with 14,864 patients demonstrated that one femtoliter increase in MPV values was associated with a rise of 29% in the risk of long-term mortality (hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.22-1.37) in CAD as a whole. The results were further supported with PIs, permutation tests and leave-one-out sensitivity analyses. MPV also demonstrated its stable and significant prognostic utility in predicting long-term mortality as a linear variable in patients treated with percutaneous coronary intervention (PCI) and presented with acute coronary syndrome (ACS) (HR 1.29, 95% CI 1.20-1.39, and 1.29, 95% CI 1.19-1.39, respectively). The meta-analysis found robust evidence on the link between admission MPV and the increased risk of long-term mortality in patients with CAD patients, as well as in patients who underwent PCI and patients presented with ACS.

The Significance of Platelet Indices in the Evaluation of Thrombocytopenia.

Thrombocytopenia, characterized by a low platelet count, poses a risk of abnormal bleeding. Traditional diagnostic methods focus on platelet count alone, but emerging evidence suggests that platelet indices like mean platelet volume (MPV) and platelet distribution width (PDW) could provide valuable insights. This study aims to investigate the role of platelet indices in thrombocytopenia assessment, exploring their potential as additional diagnostic and prognostic markers. Over a five-month period, this prospective study enrolled 80 adult patients with thrombocytopenia. Platelet indices were measured using an automated blood cell analyzer (SYSMEX XN 1000; Sysmex Corporation, Kobe, Japan), and statistical analyses were performed using the StatisticalPackage for the Social Sciences (IBM SPSS Statistics for Windows, IBMCorp., Version 23.0, Armonk,NY). The study participants showed significant age differences between hypoproductive and hyperproductive thrombocytopenia groups but no significant gender-based disparities. While platelet count and plateletcrit (PCT) didn't differ significantly between groups, individuals with hyperdestructive thrombocytopenia had higher MPV values. Platelet indices varied across clinical conditions, highlighting their potential diagnostic and prognostic value. Platelet indices like MPV, along with platelet count and PCT, offer insights into thrombocytopenia causes and prognosis. Further research is needed to confirm these findings, but integrating platelet indices into clinical practice could inform treatment decisions and reduce unnecessary procedures like bone marrow biopsies and imaging studies.

Prognostic Significance of Thrombocytopenia and Mean Platelet Volume in COPD Patients with Acute Exacerbations in ICU Settings.

BACKGROUND Platelets have important modulatory effects on inflammatory and immune-mediated pathways. Thrombocytopenia is a critical condition that is frequently encountered in the intensive care unit (ICU) and increases mortality. This retrospective study of 472 patients admitted to the ICU with acute exacerbation of chronic obstructive pulmonary disease (COPD) aimed to evaluate thrombocytopenia and mean platelet volume (MPV) with prognosis and patient mortality. MATERIAL AND METHODS A total of 472 patients diagnosed with COPD according to GOLD criteria and hospitalized in the tertiary ICU between 1 April 2018 and 11 May 2021 were included in the study. Platelets were calculated by the impetance method and MPV was simultaneously calculated based on the platelet histogram. Patients with platelet count ≤100×10⁹/L and >100×10⁹/L and patients with MPV values <7 fl, 7-11 fl, and >11fl were compared in terms of mortality and prognosis. RESULTS The mortality rate in COPD patients with thrombocytopenia was high, at 61.5%. Thrombocytopenia (P=.002), high MPV (P=.006) Acute Physiology and Chronic Health Evaluation-2 (APACHE-II) score (P=.025), length of stay (LOS) in the ICU (P=.009), mechanical ventilation duration (P<.001), leukocytosis (P<.001), high Sequential Organ Failure Assessment (SOFA) score (P<.001), LOS in the hospital (P=.035), and hypoalbuminemia (P<.001) were significantly associated with mortality. CONCLUSIONS Thrombocytopenia, high MPV, high APACHE-II and SOFA scores, LOS in the ICU and hospital, duration of mechanical ventilation, leukocytosis, and hypoalbuminemia predict mortality in COPD patients. Since infection-sepsis, hypoalbuminemia, and hypoxia can worsen this situation, ensuring early infection control, providing albumin support, and preventing hypoxia contribute significantly to reducing thrombocytopenia and mortality.

Significance of Inflammatory Markers in Primary Fibromyalgia Syndrome and Their Relation in Assessing the Disease Severity

Abstract Background Fibromyalgia syndrome (FMS) is a musculoskeletal disorder characterized by diffuse chronic musculoskeletal pain associated with various other symptoms. Although the etiology and pathogenesis of FMS are still unclear, it was reported to have possible inflammatory basis. No laboratory marker is currently available to diagnose the disease. Aim of the Work to assess the serum levels of ESR, CRP, NLR, MPV and PDW in primary Fibromyalgia syndrome patients and their relation with the disease severity and depression scores. Patients and Methods The study included 30 FMS patients, diagnosed according to the 2010 ACR (American Colleague of Rheumatology) criteria who presented to Ain Shams University Physical Medicine and Rehabilitation clinic as well as 30 healthy volunteers who served as a control group. The following laboratory tests were assessed among both groups: Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), Neutrophil Lymphocyte Ratio (NLR), Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW). FMS patients filled out The Revised Fibromyalgia Impact Questionnaire (FIQR) and Montgomery Asberg Deprssion Score (MADRS) as well. Results MPV, NLR, ESR and CRP values were significantly higher among the patients’ group (p &amp;lt; 0.05). Statistically positive correlation was found between FIQR and each of CRP (p = 0.021) and ESR (p = 0.027) levels. Another statistically significant positive correlation was found between MADRS and CRP (p = 0.01). The NLR showed marginal positive significance with FIQR. Conclusion In the light of these previous results, we can state that the serum levels of the tested inflammatory markers being mainly the acute phase reactants, have a positive relation with disease severity and depression scores, which in turn affect the quality of daily living. Accordingly, we arise the possibility of using those markers as good indicators of ongoing inflammatory process among FMS patients reflecting the severity of the disease.

Evaluation of Inflammatory Markers in Patients with Fibromyalgia Syndrome in King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia: A Cross-Sectional Study

Objectives: The goal of this study was to examine various markers in patients with FMS, including the neutrophil/lymphocyte ratio (NLR),platelet/lymphocyte ratio (PLR), platelet distribution width (PDW), and mean platelet volume (MPV). Methods: This was a cross-sectional, retrospective study conducted at King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia,involving the examination of inflammatory markers, such as PDW, NLR, and MPV. The results were evaluated with IBM SPSS version 25, and a P-value of &lt;0.05 was used to reject the null hypothesis. Results: In total, 396 participants were included in this study: 235 in the FMS group and 161 in the control group. MPV, PDW and NLR values are 10.31 ± 1.6 fL, 124.57 ± 70.0, 2.30 ± 3.2, respectively. The PDW in the control group (12.47 ± 2.5) was significantly higher than that in the FMS group (11.84 ± 2.4) (P = 0.003). Erythrocyte sedimentation rate and Vitamin D levels (P = 0.001) were significantly higher in the control group than in the FMS group, with values of 31.71 and 24.2 and 75.60 and 39.4, respectively. No significant differences were found in MPV and NLR values between the FMS and control groups. Conclusion: The findings in this study suggest that PDW and PLR are important inflammatory markers that may be beneficial in FMSdiagnosis.

A Study of the Mean Platelet Volume and Plasma Fibrinogen in Type Two Diabetes Mellitus Patients Versus Healthy Controls and Their Role as Early Markers of Diabetic Microvascular Complications.

Background Mean platelet volume (MPV) is considered an emerging biological marker of platelet function and activity. Higher MPV has been scientifically linked to diabetes mellitus, metabolic syndrome, stroke, and coronary artery disease. Plasma fibrinogen is a circulating glycoprotein, serving as an acute inflammatory marker ultimately leading to enhanced atherogenic plaque formation. We conducted this study to evaluate the crucial role of MPV and plasma fibrinogen, which showed elevated levels in diabetes mellitus patients compared to non-diabetic healthy individuals. This study also elaborates on the pivotal role that MPV and plasma fibrinogen levels play in the pathogenesis of microvascular complications, which progress and eventually lead to mortality in patients with type 2 diabetes mellitus. Methodology This study is a single-center hospital-based study including120 type 2 diabetes mellitus patients and 120 healthy non-diabetic individuals. It is across-sectional and observational study. The study wasconductedover a period of one and a half years in a medical college and hospital in a semi-urban locality in Western Maharashtra, India. We obtained informed written consent from the patients. All patients underwent thorough clinical assessment, and data were collectedusing proformas, which were latertabulated and entered in Microsoft Excel sheets. Later, the statistical data analysis was performed.Plasma fibrinogen was performed by photo-optical clot detection. MPV was analyzed by coulter principle in the central laboratory department of the parent institute. Patients above 18 years with cases of type 2 diabetes mellitus with or without any related complications, while the controls are healthy non-diabetic individuals attending the outpatient and inpatient departments of General Medicine. We excluded patients under the age of 18 years, those diagnosed with type 1 diabetes mellitus, hematological conditions associated with anemia and abnormal platelet counts, pregnant females, any acute or chronic infections, patients currently on antiplatelet medication and other drugs affecting the platelets, and all critical patients. Results The majority of patients in our study were in the age group of 41-50 years, with 49.2% having one or more microvascular complications of diabetes mellitus. In our study, out of 120 cases, 3.3% and 23.3% had raised MPV and fibrinogen levels, respectively, above the normal range. When compared with males and females, there was no statistically significant difference in the mean value of MPV and fibrinogen. On the t-test (p < 0.05), there was a statistically significant difference in the mean value of MPV and fibrinogen level between diabetics with and without microvascular complications. The t-test (p < 0.05) showed that there was a statistically significant difference among cases in the mean values of MPV and plasma fibrinogen in relation to retinopathy, nephropathy, and neuropathy, which are all microvascular complications of diabetes. Conclusion The study reveals higher levels of MPV and fibrinogen in diabetic patients compared to non-diabetic healthy individuals. In addition,higher levels of MPV and fibrinogen were present in patients with microvascular complications, correlated with age and diabetes duration.

Use of blood parameters for the prediction of mortality in patients with below‑knee amputation.

The present retrospective study aimed to investigate the value of blood parameters in predicting mortality in patients with below-knee amputation (BKA). A total of 178 patients with BKA were included in the present study. The patients were divided into two groups, namely the exitus group (n=136; 76.4%) and the survivors group (n=42; 23.6%). Patients in the exitus group were further divided into three subgroups: i) Those who experienced mortality in <1 month (n=55; 40.4%); ii) those who experienced mortality between 1-12 months (n=48; 35.3%); and iii) those who experienced mortality in >12 months after surgery (n=33; 24.3%). Binary logistic regression and a generalized linear model were used for relational analysis, and a receiver operator characteristic curve was used for diagnostic tests. It was found that the parameters of age (B=0.061; P=0.01), eosinophil-to-lymphocyte ratio (ELR) (B=-2.861; P<0.05), C-reactive protein (CRP)/albumin ratio (B=0.027; P<0.01) and mean platelet volume (MPV)/lymphocyte ratio (B=0.310; P<0.01) had a significant effect on mortality at the multivariate level. Moreover, regression coefficients showed that the effect of age, CRP/albumin and MPV/lymphocyte ratios on mortality were positive, whereas the effect of the ELR was negative. The mortality predictive values of age [area under the curve (AUC)=0.681; P=0.01], ELR (AUC=0.630; P=0.01), CRP/albumin ratio (AUC=0.746; P=0.01) and MPV/lymphocyte ratio (AUC=0.676; P<0.01) were also found to be statistically significant. For the 27.51 CRP/albumin cut-off value, the sensitivity was found to be 80.1%, whereas the specificity was 54.8%. For the 36.93 CRP/albumin cut-off value, the sensitivity was 71.3%, and the specificity was 73.8%. Furthermore, MPV (B=-0.37; P<0.01) and hemoglobin/red-blood-cell distribution width (RDW) ratio (B=5.20; P<0.01) were found to have a significant effect on the time to death at the multivariate level. The parameters MPV (AUC=0.648; P<0.01) and hemoglobin/RDW (AUC=0.673; P=0.01) had predictive value in terms of the time to death. The predictive value for MPV was found to be 64.8%, whereas that for the hemoglobin/RDW ratio was 67.3%. For the 0.54 cut-off value for hemoglobin/RDW, the sensitivity was 74.5%, and the specificity was 11.1%. By contrast, for the 0.84 cut-off value for the hemoglobin/RDW ratio, the sensitivity was 10.9% and the specificity was 81.5%. In conclusion, the CRP/albumin ratio was identified as a significant mortality parameter, whereas the hemoglobin/RDW ratio was a significant time to death predictor, according to the results of the present analysis. These results may guide clinical practices and further research in terms of predicting mortality in patients with BKA.

Correlation between Mean Platelet Volume, Fibrinogen and D-dimer with NIHSS Score

Introduction: Stroke is a clinical syndrome that develops rapidly due to focal or global brain disorders with symptoms last for &gt;24 hours and potentially cause death. Due to the consideration that this Mean Platelet Volume (MPV) marker is not invasive, easy to do and is in line with the pathogenesis of stroke, researchers are interested in carrying out this research. And hopefully this research can provide information for the world of education and health about changes in MPV, fibrinogen and D-dimer in ischemic stroke patients. So it can be taken as consideration in the early management of ischemic stroke patients. Subject and Methods: This research was an observational study with a cross-sectional design at Haji Adam Malik General Hospital from October to November 2023. The research subjects were stroke patients who were treated in emergency room and met inclusion criteria. This research was to study about correlation of MPV, fibrinogen, and D-dimer with NIHSS scores of ischemic stroke patients. The method used in this research is the Pearson correlation test where data was normally distributed. All statistical tests with a p value &lt; 0.05 were considered significant. Results: The mean MPV was 10.4 ± 1.6, while the mean NIHSS value was 19.9 ± 8.7, and there was a statistically significant correlation between the MPV value and the NIHSS score (p&lt;0.05). The mean fibrinogen was 421.9 ± 109.3, while mean NIHSS value was 19.9 ± 8.7, and there was a statistically significant correlation between fibrinogen values and NIHSS scores (p&lt;0.001). The mean D-Dimer was 8.0 ± 11.3, while the mean NIHSS value was 19.9 ± 8.7, and showed a statistically significant correlation between D-Dimer value and NIHSS score (p&lt;0.05). The r value of MPV, fibrinogen, and D-dimer on NIHSS score was 0.494; 0.495; and 0.504. The regression coefficient for MPV variable is 0.093, therefore MPV variable influence on NIHSS variable is positive. Conclusion: There is a strong correlation between D-dimer and the NIHSS score, and a moderate correlation between MPV and fibrinogen with NIHSS score.

Overall Summery of Gulf Country Employees from Bangladesh, Preliminary Evaluation for Abnormal Kidney Liver and Virally Infected Individuals Using Low-cost Tests Like CBC Parameters

Hepatitis B Viruses antigen (HBsAg), Hepatitis C Virus (HCV), Human Immunodeficiency Virus (HIV) and Syphilis is a major public concern because of shared route of transmission. Alanine transaminase (ALT) and Aspartate Aminotransferase (AST) and Bilirubin is measured for abnormal liver function test and Abnormal Kidney function is measured by creatinine. The complete blood count (CBC) is the most common examination used to monitor overall health in clinical practice as well as cheap in Bangladesh. Radiological Image could have cheap but HBsAg, HCV, HIV and Syphilis test is cost effective. The main aim to this study is to determine the viral positive, abnormal Kidney, Liver function patient’s detection by doing cheap CBC test parameters. In this study, we have calculated normal patients CBC parameter and same HBsAg, HCV and syphilis patients, abnormal kidney and liver functions patients CBC parameters have been assembled. We also find out the relation with radiological image of chest X-ray for viral positive patients. The result of the study indicated that all CBC parameter of positive HBsAg, HCV and syphilis, abnormal kidney and liver patients approximately same. But only Mean Platelet Volume (MPV) and Platelet number have significant value. Abnormal Kidney and liver patients have high MPV 11.94x10^3 and HCV, HBsAg positive patients 9.9x10^3 whereas normal patients value is 9.7x10^3. This study proves that there is significant effect for MPV value with normal and viral infected patients. This finding could have used early detection for overseas health checkup.

Enhancing endometrioma management: Diagnostic biomarkers and predictive outcomes in Ruptured vs. Non-Ruptured cases

ObjectiveTo compare the outcomes between patients undergoing surgery for ruptured endometrioma versus non-ruptured endometrioma. Study DesignThe study was conducted at Health Sciences University, Etlik Zübeyde Hanım Training and Research Hospital Infertility Clinic. All patients who had a histopathology report of endometrioma between January 2014 and December 2020 were recruited. Patient files, surgery notes and laboratory values were extracted from the electronic recording system and patients with ruptured endometriomas (RE) or non-ruptured endometriomas (NRE) were compared. ResultsOverall, 181 patients were recruited to the study. No rupture was detected in 146 (80.7 %) patients while 35 patients (19.3 %) underwent surgery for RE. Pre-operative CRP, CA 125, CA 19–9, CA 15–3, CEA and mean platelet volume (MPV) values and postoperative MPV and neutrophil/lymphocyte ratio (NLR) values were statistically significantly higher (p < 0.01) in the RE group compared to the NRE group. Post-operative lymphocyte (p = 0.029) and eosinophyl (p = 0.015) values were significantly lower in the RE group compared to the NRE group. Among the preoperative biomarkers that are evaluated for prediction of rupture; MPV, CA 19–9 and CA-15.3 had a high specifity (>75 %) but a rather low sensitivity (<60 %), meanwhile CRP, CA-125 and CEA had high sensitivity but a low specifity. ConclusionRE patients had significantly higher preoperative CRP, CA 125, CA 19–9, CA 15–3, CEA, and MPV values and postoperative MPV and NLR values while postoperative, lymphocyte and eosinophyl values were significantly lower compared with the NRE patients. Prospective studies with larger sample sizes are needed to determine biomarkers and parameters that can be used for non-invasive diagnosis of endometriosis and predict the possibility of endometrioma rupture.

The Role of Neutrophil/Lymphocyte Ratio, Platelet/Lymphocyte Ratio and Mean Platelet Volume in Diagnosis of Hydrosalpinx

Aim: It is very important to uncover the relationship between Hydrosalpinx, which occurs as a result of chronic-inflammatory-processes, and inflammatory markers. Our study aimed to investigate the role of Neutrophil/Lymphocyte Ratio(NLR), Platelet/Lymphocyte Ratio(PLR), and Mean Platelet Volume(MPV) values in the diagnosis of patients who had Hydrosalpinx. Materials and Methods: Our study included 349 patients, who applied to our clinic between March 2018-June 2023, were diagnosed with primary or secondary infertility, and for this reason underwent Hysterosalpingography. A total of 89 patients who had Hydrosalpinx and 260 patients who did not have Hydrosalpinx were divided into 2 groups, and the demographic, clinical data were compared retrospectively. Results: Neutrophil and Platelet levels were found to be significantly higher in the Hydrosalpinx-group than the control group(p:0.000).The presence of Hydrosalpinx was found to be significantly higher in patients who were diagnosed with secondary infertility(p:0.000).Neutrophil and Platelet levels were significantly higher in the bilateral-Hydrosalpinx-group than the unilateral-Hydrosalpinx-group(p:0.036,p:0.012, respectively). The NLR and PLR were found to be significantly higher in the bilateral-Hydrosalpinx-group than the unilateral–Hydrosalpinx-group(p:0.038,p:0.009, respectively). MPV were found to be significantly lower in the bilateral-Hydrosalpinx-group than the unilateral-Hydrosalpinx-group(p:0.011). Conclusion: The findings of our study support the literature data on the relationship between NLR,PLR,MPV, and chronic inflammatory processes. These markers deserve to be evaluated again and again in prospective and controlled studies, in which they will be considered together with clinical findings, to investigate their ability to predict the diagnosis of Hydrosalpinx, its severity, and clinical outcomes in infertile patients.

The Potential Value of Mean Platelet Volume and Platelet Distribution Width as Inflammatory Indicators in Surgical Necrotizing Enterocolitis.

This study aims to investigate the potential significance of mean platelet volume (MPV) and platelet distribution width (PDW) in predicting surgical neonatal necrotizing enterocolitis (NEC) and establish the correlation between MPV/PDW levels and the severity/prognosis of NEC. A retrospective study was conducted on a cohort of 372 patients diagnosed with NEC. The patients were categorized into two groups based on whether they underwent surgical therapy. Univariate /multivariate analysis were employed to compare the MPV and PDW between the two groups. Moreover, patients in surgical group were categorized into multiple subgroups based on intraoperative findings and postoperative prognosis, and the levels of MPV and PDW were compared among these subgroups. Of the 372 patients, the operative group exhibited significantly higher levels of MPV and PDW than the nonoperative group (P < 0.05). Logistic regression analysis revealed that MPV (OR = 4.895, P < 0.001) and PDW (OR = 1.476, P < 0.001) independently associated with surgical NEC. The analysis of the receiver operating characteristic (ROC) curve revealed that the area under the curve (AUC) was 0.706 for MPV alone, with a cut-off value of 11.8 fL. Similarly, the AUC was 0.728 for PDW alone, with a cut-off value of 16%. However, when MPV and PDW were combined, the AUC increased to 0.906 for predicting surgical NEC. In accordance with the intraoperative findings, the levels of MPV and PDW were found to be higher in the large area necrosis group than in the partial or mild necrosis group (P < 0.01). Furthermore, the MPV and PDW values in the death group were significantly greater than those in the survival group (P =0.040, P =0.008). MPV and PDW may serve as potentially valuable indicators for determining the need for surgical intervention and predicting the prognosis of patients with NEC.

The effect of the mean platelet volume on short-term prognosis in acute ischemic stroke patients who underwent intravenous thrombolytic therapy

Objective: To evaluate the effect of the mean platelet volume (MPV), on the short-term prognosis and bleeding complications of acute ischemic stroke patients who underwent intravenous tissue plasminogen activator (IV-tPA) treatment. Patients and Methods: Between 01.01.2018 and 01.06.2021, 314 ischemic stroke patients who applied to our clinic with acute neurological deficit were included in the study retrospectively. Alteplase was administered as IV-tPA treatment for 1 hour. MPV value was measured before the treatment and was evaluated as the main parameter. The patients were examined under 4 groups (≤8.8fL, &amp;gt;8.8 – ≤9.9, &amp;gt;9.9-≤10.8, &amp;gt;10.8fL) according to their MPV values, and age, gender, comorbidities, and treatment initiation parameters were standardized by statistical methods. It was compared whether there was a significant difference between the MPV groups in terms of short-term prognosis according to the admission National Institutes of Health Stroke Scale (NIHSS) scores and discharge NIHSS scores and also bleeding complications. Results: A total of 314 patients, 145 women with a mean age of 76.7±13.0, and 169 men with a mean age of 66.3±13.1, were included in the study. 31 patients (9.9%) died before discharge. The mean MPV value was 9.64±1.15fL and the mean NIHSS score was 9.1±4.9 at admission, and the mean NIHSS score was 4.3±4.7 at discharge. When the NIHSS difference between admission and discharge was compared in the 4 groups, it was found that the prognosis was better in Group 3 with MPV &amp;gt;9.9-≤10.8 compared to Groups 1 and 4. (p=0.002; p&amp;lt;0.01). Despite this, it was seen that low or high MPV values could not be considered as a prognostic factor alone in patients who received IV-tPA treatment, since, there was no significant difference between the 3rd group and the 2nd group in terms of NIHSS decrease and the 4th group had a worse prognosis than the 3rd group. There was no statistical significance between MPV groups in terms of hemorrhage complications (p value for intracerebral, gastrointestinal, urogenital hemorrhage complications were 0.540, 0.980, 0.783, respectively). Conclusion: In our study, it was revealed that MPV value, is not an independent risk factor in patients with acute ischemic stroke receiving IV-tPA treatment and cannot be used as a prognostic marker.

Evaluation of hematological inflammatory parameters in patients with palmoplantar pustulosis.

Palmoplantar pustulosis (PPP) is a chronic inflammatory disease of ill-defined etiopathology. Recent studies have proposed complete blood count-based hematological parameters, such as neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR), as biomarkers to monitor disease status in many inflammatory diseases. This study aimed to analyze for the first time the clinical significance of hematological parameters, including NLR, monocyte/lymphocyte ratio (MLR), PLR, mean platelet volume (MPV), plateletcrit (PCT), and pan-immune-inflammation value (PIV) in PPP patients. We retrospectively investigated the clinical and laboratory data of 237 patients with PPP and 250 sex-age-matched healthy controls (HCs). Hematological parameters were compared between patients with PPP and HCs. The correlations between these parameters and disease severity, as well as treatment response, were analyzed. NLR, MLR, MPV, PCT, and PIV values were significantly higher in PPP patients than in HCs. But in receiver-operating characteristic analyses, only monocyte count (Youden Index = 0.53), PCT (Youden Index = 0.65), and PIV (Youden Index = 0.52) performed relatively accurate distinguishment between moderate-to-severe cases and mild cases. PCT and PIV values were significantly correlated with disease severity. After treatment, both PIV and PCT values decreased significantly in the responder group but not in the non-responder group. Hematological parameters altered significantly in PPP patients. PCT and PIV can be used as simple and inexpensive biomarkers for systemic inflammation in PPP patients.

Effect of mean platelet volume and platelet count on the prognosis of branch atheromatous disease.

The purpose of this study was to investigate the predictive value of mean platelet volume (MPV) and platelet count (PC) in branch atheromatous disease (BAD). This retrospective study included 216 patients with BAD-stroke within 48h of symptom onset. These patients were divided into good and poor prognosis groups according to their 3-month modified Rankin scale scores after discharge. Multiple logistic regression analysis was used to evaluate independent predictors of poor prognosis in BAD-stroke patients. Receiver-operating characteristic (ROC) analysis was used to estimate the predictive value of MPV and PC on BAD-stroke. Our research showed that a higher MPV (aOR, 2.926; 95% CI, 2.040-4.196; p<.001) and PC (aOR, 1.013; 95% CI, 1.005-1.020; p=.001) were independently associated with poor prognosis after adjustment for confounders. The ROC analysis of MPV for predicting poor prognosis showed that the sensitivity and specificity were 74% and 84.9%, respectively, and that the AUC was.843 (95% CI,.776-.909, p<.001). The optimal cut-off value was 12.35. The incidence of early neurological deterioration (END) was 24.5% (53 of 163), and 66% of patients in the poor prognosis group had END (33 of 50). Multiple logistic regression analyses showed that elevated MPV and PC were associated with the occurrence of END (p<.05). Our results suggested that an elevated MPV and PC may be important in predicting a worse outcome in BAD-stroke patients. Our study also demonstrated an independent association of MPV and PC with END, which is presumably the main reason for the poor prognosis.

Correlation between platelet indices and preeclampsia with severe features

Backgrounds: Pre-eclampsia is a pregnancy-related syndrome with a 2-8% prevalence worldwide. In Indonesia, its incidence was 128,273 (5.3%) cases that caused 30-40% of maternal deaths. In 2021, at Karawang General Public Hospital, there are 43% cases of pre-eclampsia with 3% of complication. The pathophysiology is related to the inflammatory and coagulation system that includes platelets. Thus, platelet indices as indicators for platelet changes could be potential laboratory markers for pre-eclampsia.Objective: To examine the relationship between the platelet indices and pre-eclampsia severe features at the Karawang General Public HospitalMethods: The six months cross-sectional study was conducted at the Karawang General Public Hospital for pre-eclampsia pregnant women with at least 28 weeks of gestational age. The pre-eclampsia criteria were blood pressure higher or equal to 140/90 mmHg and qualitative proteinuria dipstick +1. The subjects were divided into two groups: pre-eclampsia with severe features and without severe features. Severe features criteria were thrombocytopenia, impaired liver function, renal insufficiency, pulmonary edema, new onset headache, and visual disturbances. Pregnant women have their blood platelet indices checked in the form of platelet crit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), and platelet large cell ratio (P-LCR). Data were analyzed with descriptive analysis (percentage), cut-off analysis, ROC curve, AUC analysis, bivariate Chi-square analysis, and multivariate logistic regression analysis.Results: There was a significant difference (p &lt; 0.05) in the value of PCT, MPV, PDW, and P-LCR between pregnant pre-eclampsia women with severe features and pregnant pre-eclampsia women without severe features. P-LCR has the best sensitivity (52.9%) and specificity (98.9%).Conclusions: There was a significant change in the value of the platelet indices (PCT, MPV, PDW, P-LCR) in pregnant pre-eclampsia women with severe features at the Karawang General Public Hospital.
