Red Cell Distribution Width Levels Research Articles

Red cell distribution width and its polygenic score in relation to mortality and cardiometabolic outcomes.

Elevated red cell distribution width (RDW) has been associated with a range of health outcomes. This study aims to examine prognostic and etiological roles of RDW levels, both phenotypic and genetic predisposition, in predicting cardiovascular outcomes, diabetes, chronic kidney disease (CKD) and mortality. We studied 27,141 middle-aged adults from the Malmö Diet and Cancer study (MDCS) with a mean follow up of 21 years. RDW was measured with a hematology analyzer on whole blood samples. Polygenic scores for RDW (PGS-RDW) were constructed for each participant using genetic data in MDCS and published summary statistics from genome-wide association study of RDW (n = 408,112). Cox proportional hazards regression was used to assess associations between RDW, PGS-RDW and cardiovascular outcomes, diabetes, CKD and mortality, respectively. PGS-RDW was significantly associated with RDW (Pearson's correlation coefficient = 0.133, p < 0.001). RDW was significantly associated with incidence of stroke (hazard ratio (HR) per 1 standard deviation = 1.06, 95% confidence interval (CI): 1.02-1.10, p = 0.003), atrial fibrillation (HR = 1.09, 95% CI: 1.06-1.12, p < 0.001), heart failure (HR = 1.13, 95% CI: 1.08-1.19, p < 0.001), venous thromboembolism (HR = 1.21, 95% CI: 1.15-1.28, p < 0.001), diabetes (HR = 0.87, 95% CI: 0.84-0.90, p < 0.001), CKD (HR = 1.08, 95% CI: 1.03-1.13, p = 0.004) and all-cause mortality (HR = 1.18, 95% CI: 1.16-1.20, p < 0.001). However, PGS-RDW was significantly associated with incidence of diabetes (HR = 0.96, 95% CI: 0.94-0.99, p = 0.01), but not with any other tested outcomes. RDW is associated with mortality and incidence of cardiovascular diseases, but a significant association between genetically determined RDW and incident cardiovascular diseases were not observed. However, both RDW and PGS-RDW were inversely associated with incidence of diabetes, suggesting a putative causal relationship. The relationship with incidence of diabetes needs to be further studied.

Neonatal hiperbilirubineminin prediktörü olarak umblikal kord kanı kırmızı hücre dağılım genişliği

Aim: Early postnatal discharge of newborns leads to the risk of hospital readmission, mostly due to neonatal hyperbilirubinemia. Therefore, early identification of newborns at high risk of hyperbilirubinemia is important. In this study, we aimed to evaluate whether cord blood red cell distribution width (RDW) levels could be used to identify newborns at high risk of developing hyperbilirubinemia.&#x0D; Material and methods: The data of all term infants who were born in our hospital between January and June 2017 whose cord blood samples were examined were reviewed retrospectively. Cord blood RDW, cord blood bilirubin, newborn/mother’s blood groups and direct Coombs’test (DCT) results were analyzed. &#x0D; Results: A total 175 newborns were included. Phototherapy was required 58 newborns in the first 48 hours postnatally. The mean cord blood RDW levels among newborns with hyperbilirubinemia was significantly higher compared to controls (18±1.6 vs. 16.4±1.0, p

YOĞUN BAKIM HASTALARINDA İNFLAMATUAR BELİRTEÇLERİN MORTALİTE ÜZERİNE ETKİLERİNİN BELİRLENMESİ

Abstract Aim: Mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), red cell distribution width (RDW) plays important role as effective factors in predicting mortality and morbidity in various diseases. In the present study we aimed to assess and compare MPV, NLR, PLR and RDW of survived and non-survived patients by examining the blood samples taken within the first hour after admission to our intensive care unit. Methods: This retrospective study included 672 patients who were hospitalized in a mixed 16 bed intensive care unit (ICU) between January 2019 and January 2020. By examining our hospital's computer-based data system, patient data of the survived and non-survived patients who were treated in the ICU were analyzed. Results: The demographic parameters of the patients (gender), concomitant disease, and laboratory parameters including HTC, PLT, WBC, MPV and PLR were not significantly different between the survived and non-survived patients. RDW, albumin, CRP and NLR were found statistically different between the study groups. Conclusions: The elevated RDW, NLR and CRP levels were found more significant than the other inflammatory markers for determining mortality of the critically ill patients. In addition, evaluation of albumin level was found important in defining the prognosis of the intensive care unit patients.

The Relationship Between Prognosis and Red Cell Distribution Width (RDW) and RDW-Albumin Ratio (RAR) in Patients with Severe COVID-19 Disease.

The present study aimed to investigate the relationship between prognosis and the red cell distribution width (RDW) and the RDW-albumin ratio (RAR) in patients with coronavirus diseases 2019 (COVID-19), since serum albumin and RDW levels may reflect inflammatory conditions. A total of 289 patients who had been diagnosed with severe COVID-19 in the emergency department were retrospectively analyzed. The RAR levels were calculated by dividing RDW-CV by albumin. Patient groups (survivors, dying patients, those who received mechanical ventilation (MV) support or not, and those who needed vasopressors or not) were compared with regard to RDW-SD, RDW-CV and the RAR levels. RDW-SD, RDW-CV and the RAR levels were found to be statistically significantly higher in patients who died, and who received MV and vasopressor support, compared to those who survived and did not receive support (p<0.001 for all). In addition, while the cut-off value of RAR was >5.43, the sensitivity was 91.6%, the specificity was 93.7%, NPV was 93.1% and the AUC was 0.965 in predicting mortality (p<0.001). Logistic regression analysis showed that RDW-SD and RAR were independent risk factors for mortality in patients with severe COVID-19. Elevated RDW and RAR levels at the time of admission may independently predict mortality and the need for vasopressor or MV support.

The evaluation of red cell distribution width in type 2 diabetic patients with acute ST- segment elevation myocardial infarction in Erbil city: a cross sectional study

Background: The relationship of high red cell distribution width (RDW) with many hematological and angiographic characteristics in type 2 diabetic patients with acute ST-segment elevation myocardial infarction (STEMI) is still a matter of debate.&#x0D; Objective: To evaluate the relationship of high RDW with multiple hematological and angiographic characteristics in type 2 diabetic patients with acute STEMI.&#x0D; Patients and Methods: In this cross-sectional study, one hundred patients with acute STEMI who underwent coronary angiography were enrolled. The patients were divided into two groups according to the presence of type 2 diabetes mellitus (T2DM); group I, diabetic patients and group II, non-diabetic patients. Further division was made to group I patients based on how high or low RDW level was; subgroup A patients with high RDW level, and subgroup B patients with low RDW level. The groups were evaluated and compared regarding baseline demographic, laboratory and angiographic characteristics.&#x0D; Results: The mean RDW was higher (P=0.04) in group I compared to group II. The mean values of white blood cell (WBC) , RDW, CK-MB, Troponin T high sensitive (hs) , and HbA1C levels were significantly higher in subgroup A compared to subgroup B (P=0.007, 0.003, 0.03 and &lt; 0.001, respectively). Subgroup A patients have significantly more extension of coronary diseases than subgroup B (P=0.001). A positive correlation was detected between RDW and WBC, CK-MB, Troponin T hs, HbA1C as well as number of diseased vessels in diabetic patients (0.76, 0.4, 0.98 and 0.79, respectively).&#x0D; Conclusion: Diabetic patients with acute STEMI had higher levels of RDW than non-diabetics and higher levels were positively correlated with inflammatory and poor outcome cardiovascular markers as well as multiple vessel diseases involvement. It was also correlated with poor glycemic control represented by high HbA1C.

Red Blood Cell Distribution Width Level as Reliable Diagnostic and Prognostic Biomarker in Septic Patients: A Case-Control Study

Red Blood Cell Distribution Width Level as Reliable Diagnostic and Prognostic Biomarker in Septic Patients: A Case-Control Study

HAEMATOLOGICAL AND BIOCHEMICAL CHARACTERISTICS OF FINISHER BROILER CHICKENS FED ROASTED BAMBARA NUT (Vigna subterranea L.)-BASED DIETS

The study was conducted to investigate the haematological and biochemical parameters of finisher broiler chickens fed roasted Bambara nut-based diets. A total of 96-day-old Marshal Strain broiler birds were assigned to four treatments (0, 10, 20 and 30%) replicated four times in a completely randomized design (CRD) comprising of 6 birds in each. Bambara nut seeds were roasted, dried and milled into fine powdery roasted Bambara nut meal. The meal was then incorporated in the diets at 0, 10, 20 and 30% inclusion levels. Samples were then analyzed for proximate composition. At the end of the 8 weeks feeding trial, three birds were selected on the basis of average pen weight from each group and used for the determination of blood indices. Data collected were subjected to analysis of variance (ANOVA) using statistical analysis system (SAS) package. Results revealed no significant (p&gt;0.05) differences in most of the parameters measured. However, there were significant (p&lt;0.05) differences in red cell distribution width (RDW), and monocytes (MON) levels across the treatments. The result also indicated that RDW% levels decreased with increasing levels of roasted Bambara nut meal (RBM). The result of serum calcium revealed significant (p&lt;0.05) differences across the treatments where T4 (30%) presented the highest value (2.43mmol/L). It was concluded that inclusion of Bambara nut meal in the diets of finisher broiler chickens at 30% enhanced the levels of RDW and serum calcium.

Artmış RDW Değeri ile Kolelitiazis İlişkisi

Objective: Red cell distribution width (RDW) ,an index of heterogenity of circulating red blood cell, has recently been found to be associated with multiple diseases and used as a marker to predict outcome in these patients. In the present study we aimed to investigate if RDW value is associated with cholelithiasis and symptoms of the disease.Material- Method: A total of 204 women (101 with cholelithiasis and 103 without the disease ) were included to the study. The demographic and the laboratory data of the routine complete blood cell parameters including RDW values were recorded. Women with cholelithiasis were divided into symptomatic or non-symptomatic group according to presence of biliary colic or pain. The patients were compared in terms of their demographic and laboratory characteristics.Results: Age and BMI were similiar between groups in the study population. In our study population mean RDW value was signifi¬cantly higher in women with cholelithiasis than without disease. However in subgroup analysis there was no significant difference of RDW value between symptomatic group and nonsymptomatic group Conclusion: In conclusion we demonstrated an association between serum RDW level and cholelithiasis in our study but not with disease symptom. However further studies are needed to understand the role of RDW in patients with cholelithiasis and if this simple , inexpensive and routinely reported parameter can be used for prognostic information in this disease.

Red cell distribution width and mean platelet volume in rheumatoid arthritis patients: Its association with disease activity

IntroductionHemogram parameters have been recently proposed as markers of inflammation in various studies from different parts of the world. Two of these hemogram parameters are red cell distribution width (RDW) and mean platelet volume (MPV). AimTo evaluate the relation between RDW and MPV with disease activity of rheumatoid arthritis. To assess whether RDW and MPV can be used to follow disease activity in RA patients. MethodsThis is an observational cross-sectional study that was carried out on 60 rheumatoid arthritis patients who fulfilled the ACR/EULAR2010 classification criteria of RA attending to Rheumatology and Rehabilitation inpatient and outpatient clinics at Zagazig University Hospitals. All cases were subjected to full history taking, clinical examination, and laboratory investigations; differential complete blood picture (CBC), acute phase reactants (CRP and ESR), rheumatoid factor (RF) and anti-cyclic-citrullinated peptide (anti-CCP) antibodies. Disease activity was measured by disease activity score 28 (DAS28). ResultsThe cut-off levels of RDW and MPV were 14.85 and 11.25. Patients with RDW>14.85 had higher Disease Activity Score 28 (DAS28; p=0.0003), ESR (p=0.0001) and CRP (p=0.0001). RDW was positively correlated with disease activity markers (ESR, CRP and DAS28) in rheumatoid arthritis patients. But, DAS28 was not different between patients with MPV>11.25 and <11.25. ConclusionRDW was strongly correlated with disease activity. Also, RDW was better than ESR and CRP in detecting RA disease activity. According to these findings we suggest that RDW can be used in clinics to follow disease activity. In addition, RDW is widely available; as it's usually included in routine complete blood picture and there will be no need for further cost.

Clinical Significance of the Relationship Between D-dimer and Erythrocyte Distribution Width in Covid-19 Patients

Introduction: Red cell distribution width (RDW) is a marker that can be used in the presence of systemic inflammation and evaluating thromboembolic condition.We aimed to evaluate the relationship between RDW and the level of D-dimer known as related to adverse events in Coronavirus disease 2019 (COVID-19) in this study. Methods: One hundred twenty two patients with COVID-19 and 62 healthy individuals with age and sex-matched were enrolled in the present study. The patients were divided into two groups based on evaluating their D-dimer level. The first group contained 45 patients with higher D-dimer level whereas the second group contained 77 patients with normal D-dimer level. Results: RDWvalues were found to be higher in patients with COVID-19 and higher D-dimer level than patients with normal D-dimer level and control group. These results were found to be statistically significant (P=0.006 and P=0.013, respectively). Among patients with COVID-19, a positive correlation was observed between RDW and D-dimer level (r=0.270, P=0.003). Among the various variables associated with higher D-dimer in multivariate logistic regression analyses, RDW detected an independent predictor of higher D-dimer in COVID-19 patients (95% CI: CI:0.322-0.979, P=0.042). Conclusion: The results indicated that high RDW values in patients with COVID-19 disease could be used as a marker in clinical follow-up of patients as D-dimer.

Red cell distribution width levels in patients with pseudoexfoliation syndrome and pseudoexfoliation glaucoma

The purpose of this study was to assess the levels of red cell distribution width (RDW) in patients with pseudoexfoliation syndrome (PEX) and pseudoexfoliation glaucoma (PEXG), and to compare their RDW values with healthy controls. 40 patients with PEX, 40 with PEXG, and 80 control subjects were enrolled in this study. Complete ophthalmologic examination and complete blood count measurements were performed of all subjects. Complete blood counts were performed within one hour of blood collection. RDW levels were significantly higher in patients with PEX and PEXG than in controls (P = 0.027 and P < 0.001, respectively). Furthermore, a significant difference was found in RDW values between PEXG and PEX groups (P = 0.016). RDW levels were gradually increased from control group to PEXG group (P < 0.001). Multivariate logistic regression analysis revealed that RDW was independently associated with the presence of PEX/PEXG (odds ratio 1.765, 95% confidence interval (CI) 1.095-2.867, P = 0.013). We conclude that RDW may be a useful marker for predicting the presence of PEX and progression to PEXG.

Anemia Profile in Pediatric Patients at Pediatric Intensive Care Unit (PICU) of Dr. Soetomo General Academic Hospital

Introduction: Anemia often occurs in critically ill children and is associated with increased morbidity and mortality in women and children and impaired cognitive and behavioral development in children. Objective: This study aims to understand the profile and characteristics of anemia patients in the critical care population. Materials and Methods: This is a retrospective, descriptive study of the patient's medical records. Data were collected by the total sampling technique. Results: Among 203 patients, 52% were anemic at admission to the Pediatric Intensive Care Unit (PICU), while 45% were anemic at discharge. Anemia tends to be more common in older age and male individuals with their chief complaints being respiratory symptoms, higher mean Red Cell Distribution Width (RDW) levels, and poorer nutritional status. There were 84 patients (41%) who received Packed Red-Cells (PRC) transfusions, among them there were 54 patients (51%) who were anemic at PICU admission. Of the 84 patients who received PRC transfusions during their PICU stay and 43 patients (47%) were anemic on PICU discharge. Conclusion: Anemia is quite common in critically ill children and is dominated by male patients aged under 5 years. Anemia also mostly happens in patients with higher organ dysfunction scores and poorer nutritional status than nonanemic patients. Half of the patients with anemia at the PICU also received PRC blood transfusion.

P773: THE ELEVATION OF RED BLOOD CELL DISTRIBUTION IS AN INDEPENDENT PROGNOSTIC FACTOR FOR JUVENILE MYELOMONOCYTIC LEUKEMIA

Background: Juvenile myelomonocytic leukemia (JMML) is an overlapping myeloproliferative and myelodysplastic disorder of infants and early children. The existing clinical and laboratory prognostic features are inadequate to predict a worse outcome alone. New prognostic indicators are urgently needed since the great clinical heterogeneity. Red cell distribution width (RDW) is a parameter of the complete blood count (CBC) measured automatically by haematology analyzers to reflect the heterogeneity of erythrocyte size. In recent years, RDW has been suggested to have a high negative value for outcomes in various cancers. However, the role of RDW at diagnosis in patients with JMML is still unclear. Aims: Our aim is to investigate the prognostic role of RDW in children with JMML. Methods: We conducted a single center retrospective study to investigate the prognostic role of RDW in children with JMML. Seventy-seven patients were enrolled from January 1, 2008 to November 31, 2019. Survival rates were calculated and compared using Kaplan-Meier methods and log-rank tests. Univariate and Multivariate analysis was carried out according to the Cox proportional hazard regression model. Results: The mean red cell distribution width standard deviation (RDW-SD) for patients is 53.3(39.3-73.7) fl. Cox proportional hazard models showed that patients with RDW-SD >50.50fl at diagnosis were significantly associated with poor overall survival (OS) (HR = 5.22, CI = 1.50-18.21, P=0.010). The multivariate analysis demonstrated that the RDW-SD count was the independent risk factor for OS. Patients with PTPN11 mutation and RDW elevation displayed the worst survival rate, in comparison with other subgroups (P=0.00013). Summary/Conclusion: The results suggested that the elevated level of RDW is an independent prognostic factor for JMML. Furthermore, the PTPN11 mutation and a high RDW level may involve a synergy during the natural course of JMML.

Does occupational ionizing radiation exposure in healthcare workers affect their hematological parameters?

Blood cells are used as the most sensitive marker to determine the effects and intensity of ionizing radiation. This descriptive study aimed to evaluate the effect of radiation exposure on hematological parameters in healthcare workers who were exposed to radiation in a university hospital between May and June 2021. A total of 339 participants were included, of which 169 (49.9%) were radiation workers and 170 (50.1%) were in the control group. A decrease was observed in white blood cell and neutrophil counts in those exposed to ionizing radiation for less than 10 years; however, white blood cell, neutrophil, hemoglobin levels decreased, and red cell distribution width (RDW) levels increased in those exposed to ionizing radiation for 10 years or more (p < 0.005). A statistically significant increase was observed in the RDW and lymphocyte levels as the years of work experience in the profession increase in the group exposed to IR. The findings indicate that the effect of low-dose ionizing radiation on the hematopoietic system is related to the frequency and duration of the dose. Hematological parameters can be sensitive biomarkers of low-dose ionizing radiation; possible disturbances in the hematopoietic system can be recognized before the onset of symptoms, and necessary precautions can be taken promptly.

Red Cell Distribution Width and Its Association with Neonatal Bacteremia: A Case-Control Study

Background: Bacteremia is a major cause of prolonged hospital stay and mortality in neonates and its early diagnosis remains a challenge to pediatricians. Red cell distribution width (RDW) is a component of a complete blood count test which is accessible and inexpensive and has been reported to be a possible diagnostic marker for neonatal bacteremia. This study determined the association of RDW with neonatal bacteremia in term and preterm neonates. Methodology: This is a retrospective case-control study of 26 bacteremic neonates as cases and 104 non-bacteremic neonates, either symptomatic or with risk factors for bacteremia, as controls. Included newborns were seen between January 1, 2010 to September 30, 2021. Laboratory data obtained were CBC, C-reactive protein and blood culture. Results: RDW values between bacteremic and non-bacteremic neonates were not significantly different. There was an association between RDW and neonatal bacteremia at an RDW level of &gt; 16.1, where the likelihood of bacteremia was three times higher compared with lower RDW values. Significantly lower levels of hemoglobin, hematocrit, RBC count, WBC count, platelet count, MCH and MCHC, and a higher CRP level were seen among bacteremic neonates compared to those who were not. The median RDW for both term and preterm neonates was close to 16, with a narrow inter-quartile range at 1 and 2 for controls and cases, respectively. The range (minimum to maximum) of RDW values of bacteremic preterm neonates was more variable than those of term neonates. Using RDW to detect bacteremia, it had an equivocal discriminatory power or AUC of 0.6056. We found insufficient evidence to demonstrate a correlation between RDW and other CBC parameters, except for MCHC. For MCHC, the results suggest a very weak and indirect correlation. Conclusion: RDW was not significantly different between bacteremic and non-bacteremic neonates, but there was a suggested association between RDW and bacteremia at an RDW level of &gt; 16.1, at which level there was a 3-fold risk for bacteremia.

Association of RDW, NLR, and PLR with Atrial Fibrillation in Critical Care Patients: A Retrospective Study Based on Propensity Score Matching

Objective Previous studies have shown inconsistent results in relation to the red cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR) of atrial fibrillation (AF). This retrospective study is aimed at detecting the association of RDW, NLR, and PLR with AF. Methods A total of 4717 critical care patients were screened from the Medical Information Mart for Intensive Care- (MIMIC-) III database. The patients were separated into the non-AF and AF groups. The imbalances between the groups were reduced using propensity score matching (PSM). ROC curves were generated to detect the diagnostic value of RDW, NLR, and PLR. Logistic regression analysis was used to detect the risk factors for AF. Results A total of 991 non-AF patients paired with 991 AF patients were included after PSM in this study. The RDW level in the AF group was significantly higher than that in the non-AF group (15.09 ± 1.93vs. 14.89 ± 1.91, P = 0.017). Neither NLR nor PLR showed any significant difference between the two groups (P > 0.05 for each). According to ROC curve, RDW showed a very low diagnostic value of AF (AUC = 0.5341), and the best cutoff of RDW was 14.1 (ACU = 0.5257, sensitivity = 0.658, specificity = 0.395). Logistic regression analysis showed that an elevated RDW level increased 1.308-fold (95%CI = 1.077-1.588, P = 0.007) risk of AF. Neither elevated NLR nor elevated PLR was a significant risk factor for AF (OR = 0.993, 95%CI = 0.802-1.228, P = 0.945 for NLR; OR = 0.945, 95%CI = 0.763-1.170, P = 0.603 for PLR). Conclusions Elevated RDW level but not NLR or PLR levels is associated with AF. RDW > 14.1 is a risk factor for AF, but its diagnostic capacity for AF is not of great value.

Associations of Complete Blood Count Parameters with Disease-Free Survival in Right- and Left-Sided Colorectal Cancer Patients.

Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide. Some complete blood count (CBC) parameters are found to be associated with CRC prognosis. In this study, ninety-seven pretreated CRC patients were included, and the patients were divided into two groups: left-sided and right-sided, depending on the anatomical location of the tumor. Based on clinicopathologic features including tumor budding, disease stages, and tumor anatomical location, levels of CBC parameters were compared, and disease-free survivals (DFS) were determined. There were differences between patients with different tumor budding scores for only three parameters, including red cell distribution width (RDW), numbers of platelets, and mean platelet volume (MPV). Furthermore, numbers of WBCs, monocytes, and MPV in CRC patients with early disease stages were higher than those with advanced stages. However, levels of eosinophil in CRC patients with advanced stages were higher than those with early stages. Depending on the tumor anatomical location, we observed that numbers of red blood cells (RBCs), hemoglobin (Hgb), and hematocrit (Hct) in CRC patients with left-sided tumors were higher than those with right-sided tumors. We found that low levels of MPV were associated with shorter DFS. However, high levels of eosinophils were associated with shorter DFS in all CRC patients. When patients were divided based on the tumor anatomical location, higher levels of MPV, MCHC, and Hgb were associated with better DFS in the left-sided but not right-sided CRC patients. However, left-sided, but not right-sided, CRC patients with high levels of eosinophil and RDW had shorter DFS. Furthermore, right-sided, but not left-sided, CRC patients with high levels of platelets tended to have a shorter DFS. Our data show that MPV and eosinophils could serve as potential prognostic biomarkers in pre-treatment CRC patients, regardless of the tumor anatomical location. Additionally, lower levels of MPV, MCHC, and Hgb, and high levels of eosinophils and RDW could be negative predictive biomarkers in left-sided CRC patients.

Tip 1 ve Tip 2 Psöriasiste Hematolojik Parametrelerin Metabolik Sendromla Olan İlişkisi

Objective: Psoriasis is a chronic, inflammatory disease with a rate of 2% in the population, with periods of remission and exacerbation. Psoriasis has been accepted as an independent risk factor for cardiovascular diseases and is known to be closely related to metabolic syndrome. It is known that the mean platelet volume (MPV), the platelet distribution width (PDW), the red blood cell distribution width (RDW) levels are parameters predicting systemic inflammation. Studies have found that some of these parameters can be used to predict metabolic syndrome in patients with psoriasis. In the literature, there is no study showing the relationship between the frequency of metabolic syndrome (MS) and hematological parameters by evaluating type 1 and type 2 psoriasis separately. &#x0D; Materials and Methods: A total of 186 participants were included in the study, 93 patients over 18 years of age with psoriasis diagnosed and 93 age and gender equivalent control groups, who applied to the dermatology clinic. &#x0D; Results: While PDW was significantly different between psoriasis and control group, RDW was significantly different in the type 2 psoriasis group compared to the type 1 psoriasis group. Although MPV, RDW, and PDW were higher in the MS groups for both type 1 and type 2 psoriasis groups, and they did not create a statistically significant difference in any of them. &#x0D; Conclusions: This study showed that the frequency of MS and related parameters were different between patients with type 1 and type 2 psoriasis, and we found that type 2 psoriasis was more associated with MS. In addition, we think that among the inflammatory parameters, especially RDW, may be an important marker for type 2 and type 1 psoriasis and comorbidities.

Investigation of the relationship between inflammatory blood parameters and seborrheic dermatitis.

Seborrheic dermatitis (SD) is a chronic inflammatory disease. The etiology of the disease is still unknown. The systemic immune-inflammation index (SII), red cell distribution width (RDW), mean platelet volume (MPV), C-reactive protein (CRP), monocyte to HDL cholesterol ratio (MHR), platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR) have all been reported as inflammatory markers in recent studies. However, these inflammatory markers have not been explored in SD patients. This study aimed to explore inflammatory and hematological parameters in SD patients with healthy controls (HCs) and evaluate their possible relationship with disease severity. One hundred patients who presented to our hospital were diagnosed with SD and 74 HCs were retrospectively included in our study. The seborrheic dermatitis area severity index (SDASI) score was used to assess the severity of the SD. The patient group's mean PLR, MPV ve CRP levels were statistically significantly higher than the HCs (p<0.05). There was no statistically significant difference in the patients compared with the control group regarding RDW, NLR, MHR, and SII levels (p>0.05). There was no statistically significant correlation between NLR, PLR, MPV, monocyte/HDL cholesterol, SII levels with age, and SDASI in the patient group. There was a significant correlation between CRP with age and RDW with SDASI score. Hematological parameters and CRP are low-cost tests. These tests can be used to define inflammation levels in inflammatory diseases. This study shows that PLR, CRP, and MPV may be used as novel inflammatory markers in SD.
