Can red blood cell distribution width (RDW) level predict the severity of acute exacerbation of chronic obstructive pulmonary disease (AECOPD)? Int J Clin Pract 2021; 75:e14730. [PMID: 34383359 DOI: 10.1111/ijcp.14730] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 08/09/2021] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Elevated red blood cell distribution width (RDW) levels were associated with mortality in patients with stable chronic obstructive lung pulmonary diseases (COPD). There are limited data about RDW levels in acute exacerbation of COPD (AECOPD). AIM/OBJECTIVE The association of the RDW levels with the severity of AECOPD was evaluated according to admission location, (outpatient-clinic, ward and intensive care unit (ICU)). METHODS Cross sectional retrospective study was designed in tertiary care hospital for chest diseases in 2015. Previously COPD diagnosed patients admitted to hospital outpatient-clinic, ward and ICU due to AECOPD were included in the study. Patients demographics, RDW, biomarkers (CRP, RDW, Neutrophil to lymphocyte ratio (NLR), platelet to mean platelet volume (PLT-MPV)) C-CRP, biochemistry values were recorded from hospital electronic system. RDW values were subdivided below 0.11% (low), above and equal 0.15% (high) and between 0.11%-0.15% (normal). Neutrophil to lymphocyte ratio (NLR) and platelet to mean platelet volume (PLT-MPV) were also calculated. Biomarker values were compared according to where AECOPD was treated. RESULTS 2771 COPD patients (33% female) and 1429 outpatients-clinic, 1156 ward and 186 ICU were enrolled in the study. The median RDW values in outpatients-clinic, ward and ICU were 0.16 (0.09-0.26), 0.07 (0.01-0.14) and 0.01 (0.00-0.07) respectively (P < .001). In outpatient to ward and ICU, low RDW values were significantly increased (31%, 66%, 83%, respectively) and high RDW values significantly decreased (54%, 24%, 10%) (P < .001). According to attack severity, low RDW values were determined. CONCLUSION Patients with AECOPD, lower RDW values should be considered carefully. Lower RDW can be used for decision of COPD exacerbation severity and follow up treatment response.

Abstract
Platelets play an important role in the pathophysiology of chronic obstructive pulmonary disease (COPD) by mediating thrombotic, inflammatory, and immune processes in the lung. We conducted a systematic review and meta-analysis of studies investigating the platelet count and three platelet indices, mean platelet volume (MPV), platelet distribution width (PDW), and platelet to lymphocyte ratio (PLR) in stable COPD vs. non-COPD patients and in stable COPD vs. acute exacerbation of COPD (AECOPD) patients (PROSPERO registration number: CRD42021228263). PubMed, Web of Science, Scopus and Google Scholar were searched from inception to December 2020. Twenty-seven studies were included in the meta-analysis, 26 comparing 4,455 stable COPD patients with 7,128 non-COPD controls and 14 comparing 1,251 stable COPD with 904 AECOPD patients. Stable COPD patients had significantly higher platelet counts (weighted mean difference, WMD = 13.39 x109/L, 95% CI 4.68 to 22.11 x109/L; p < 0.001) and PLR (WMD = 59.52, 95% CI 29.59 to 89.44; p < 0.001) than non-COPD subjects. AECOPD patients had significantly higher PLR values than stable COPD patients (WMD = 46.03, 95% CI 7.70 to 84.35; p = 0.02). No significant differences were observed in MPV and PDW. Between-study heterogeneity was extreme. In sensitivity analysis, the effect size was not modified when each study was sequentially removed. The was no evidence of publication bias. In our meta-analysis, specific platelet biomarkers were associated with stable COPD (platelet count and PLR) and AECOPD (PLR). However, the observed heterogeneity limits the generalizability of the findings. Further studies are required to determine their prognostic utility and the effects of targeted interventions in COPD.

Abstract
BACKGROUND AND OBJECTIVE Platelet activation, inflammatory reactions and oxidative stress are common pathogenesis of chronic obstructive pulmonary disease (COPD) with pulmonary heart disease (PHD). Mean platelet volume (MPV) and red blood cell distribution width (RDW) form part of the pathomechanisms of these conditions. Here, we investigated whether MPV and RDW can be biomarkers of PHD occurring secondary to COPD. MATERIALS AND METHODS This was a retrospective study on 229 participants with COPD. Among them, 69 had PHD. Complete blood count (CBC), blood gas analysis, pulmonary function tests and echocardiography were analyzed. RESULTS MPV and RDW-standard deviation (RDW-SD) were significantly higher in patients with PHD than in patients without PHD (P ≤ 0.001). MPV and RDW-SD were positively correlated with pulmonary artery pressure (PAP) and the size of the right ventricle (P ≤ 0.05). Multivariate regression analysis showed that the risk of PHD increased 3-fold per unit rise in MPV (OR = 2.901, P ≤ 0.001). We observed that the risk of PHD increased 1.5 times per unit rise in RDW-SD (OR = 1.371, P ≤ 0.001).The AUC of ROC curve for the combined MPV and RDW-SD in predicting PHD among COPD patients was 0.900 (95%CI: 0.846-0.954, P ≤ 0.001), with a sensitivity of 76.8% and a specificity of 99.4%. CONCLUSIONS Both MPV and RDW-SD were significantly elevated and correlated with disease severity in COPD patients with PHD. A combination of these two parameters presents an effective biomarker of PHD.

Abstract
Objective: To determine the trends of utilization of CBC parameters in patient management among doctors in different hospitals in Kashmir, Pakistan. Methodd: A self-administered questionnaire-based survey was carried out amongst doctors working in four hospitals of Kashmir i.e. Combined Military Hospital, Muzaffarabad, Combined Military Hospital, Rawalakot, Abbas Institute of Medical Sciences, Muzaffarabad, and District Hospital, Kotli during August to December 2017. Results: Out of 500 physicians, 217 physicians answered the questionnaire, representing a response rate of 43.4%. Only three of the 11 parameters in the CBC report i.e. hemoglobin, white blood cell count and platelets were selected as frequently or always useful by more than 80% of physicians. Rest of the eight parameters of the CBC were found useful by less than 80% of the physicians. Most agreed that the current format of a CBC report gives adequate information. Conclusion: The present study concludes that majority of the physicians utilize only three of the basic parameters on the complete blood count. An educational intervention can be planned for the physicians to increase their knowledge about the utility of other parameters.

Abstract
Platelets are most important in providing cellular hemostasis but also take part in inflammation and immune processes. Increased platelet size has been regarded as a feature describing a young and more reactive subpopulation until studies were published which questioned this concept. Moreover, changes of platelet size given by the mean platelet volume (MPV) were described for immune thrombocytopenia, cardiovascular disease, atherosclerosis, venous thromboembolism, chronic lung disease, sepsis, cancer-associated thrombosis, autoimmune disorders, and others. This review summarizes the literature on what is known about platelets with different size and describes controversies of studies with large and small platelets putting a focus on their thrombogenicity, age, and on the association of MPV with the mentioned diseases.

Abstract
Objective To evaluate the feasibility of mean platelet volume (MPV) as a biomarker for
chronic obstructive pulmonary disease (COPD). Methods A systematic search for studies published up to March 2019 was performed in
the PubMed and Web of Science databases. Three independent investigators
screened the titles and abstracts of including studies according to
eligibility criteria. The Newcastle–Ottawa Scale was used to assess the
quality of eligible studies, and statistical analyses were performed using
Review Manager version 5.3. Results A total of eight studies with 1230 COPD patients and 443 healthy controls
were included in our meta-analysis. No significant differences in MPV level
were identified in pairwise comparisons of the acute exacerbations of COPD
(AECOPD), stable COPD, and control groups. Furthermore, no significant
correlation was observed between MPV level and systemic inflammatory
biomarkers. Conclusions MPV does not appear to represent a suitable biomarker of disease phase or
inflammatory burden in COPD. However, future large-scale studies should be
performed to further investigate the relationship between MPV and COPD.

Abstract
Background: Pulmonary hypertension (PH) is one of the most common complications developed during the course of chronic obstructive pulmonary disease (COPD). Platelet activation plays an important role in its pathophysiology, and mean platelet volume (MPV) is considered a respectable index of platelet activation. The aim of this work is to assess the ability of MPV in predicting PH secondary to COPD as well as its severity. Methods: A cross-sectional study was conducted on 228 stable COPD patients. CBC, echocardiography, and pulmonary function tests were performed. Results: The prevalence of PH in stable COPD patients was high (63%), and the majority of patients had a mild degree (33%). There was no significant association between PH presence with different COPD grade, but, in very severe COPD, severe PH was significantly presented. MPV in COPD patients with PH was significantly higher than those without (9.02±1.14 vs 7.11±0.98, P<0.001). Moreover, a significant statistical rising of MPV with increased severity of PH. Multivariate regression analysis of predictors of PH demonstrated that; MPV is a real predictor of PH in such patients. The likelihood probability of PH increased up to 7-times with increasing one unit of MPV; (OR=6.7). A cut-off value of MPV >7.25 had 96% sensitivity and 76% specificity in predicting PH. Conclusion: MPV was higher in COPD patients with PH and positively correlated with PH severity. If the data are to be confirmed, MPV may be taken into consideration in decision-making and management of COPD patients.

Abstract
INTRODUCTION The Mean Platelet Volume (MPV) is a platelet activation biomarker that has been recently correlated with disease activity in SLE. We aimed to evaluate the MPV in patients with SLE comparing it with healthy individuals, to study the correlation between MPV and SLE Disease Activity Index (SLEDAI) in SLE patients and to analyze possible correlation between MPV and Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP), and complement components C3 and C4. METHODS This is a cross-sectional study in which 81 patients with SLE according to the American College of Rheumatology (ACR) diagnostic classification criteria and 58 healthy controls were included. Active disease was defined as SLEDAI>0. RESULTS Patients with active SLE had decreased MPV when compared to inactive disease group (10.0±0.7fL vs. 10.7±1.0fL, p=0.005, respectively) and when compared to control group (10.9±1.0fL, p<0.001). Our study found a weak negative correlation between the SLEDAI and the MPV (r=-0.29, p=0.009). There was no correlation between MPV and CRP, ESR, C3 and C4. Also, no correlation between SLEDAI and CRP, ESR, C3 and C4 was found. CONCLUSION MPV decreases in patients with active SLE and is inversely correlated with SLEDAI.

Abstract
Background Cyclophilin A (CyPA) is a secreted molecule that is regulated by inflammatory stimuli. Although inflammation has an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD), little is known regarding the relationship between serum CyPA and COPD. Methods Ninety-three COPD patients with acute exacerbation were enrolled in the study and were reassessed during the convalescence phase. Eighty-eight controls were matched for age, gender, body mass index, smoking index and comorbidity. The basic clinical information and pulmonary function of all participants were collected. Serum levels of CyPA and other inflammation indexes were further measured. Results Serum CyPA was significantly increased in convalescent COPD patients compared to healthy controls, and further elevated in COPD patients with acute exacerbation. Serum CyPA positively correlated with serum interleukin-6, matrix metalloproteinase-9 and high-sensitivity C-reactive protein in both the exacerbation and convalescence phases of COPD. Furthermore, it negatively correlated with percent value of forced expiratory volume in 1 second (FEV1%) predicted and FEV1/forced vital capacity in convalescent COPD patients. Conclusion These results suggest that serum CyPA can be used as a potential inflammatory biomarker for COPD and assessment of serum CyPA may reflect the severity of inflammation in COPD.

Abstract
Background: Amongst the different clinical and laboratory parameters used to monitor disease activity in systemic lupus erythematosus (SLE), mean platelet volume (MPV) is a novel biomarker. Although MPV has been studied in other rheumatological conditions like rheumatoid arthritis, its role in adult SLE needs to be defined, especially in Pakistan.
Methods: The aim of this study was to evaluate the role of MPV as a biomarker of disease activity in SLE. Fifty patients were recruited through a consecutive non-probability sampling technique for this cross-sectional study. On the basis of their SLE disease activity index (SLEDAI) score of greater or lesser than 5, these 50 participants were divided into two equal groups respectively;25 patients with active SLE, and another 25 participants with stable, inactive lupus. MPV was measured in each group and compared using SPSS version 16. MPV was also correlated with SLEDAI and erythrocyte sedimentation rate (ESR). Independent sample t-test and Spearman’s rho and Pearson’s correlation tests were applied. Sensitivity and specificity of MPV were checked through ROC analysis.
Results: The MPV of patients with active SLE (n=25, mean [M]=7.12, SD=1.01) was numerically lower than those in the inactive-SLE group (n=25, M= 10.12, SD=0.97), and this was statistically significant (
P<0.001). MPV had an inverse relationship with both ESR (r=-0.93,
P<0.001) and SLEDAI (r
s= -0.89,
P<0.001). However, there was a strong positive correlation between ESR and SLEDAI (r
s=0.90,
P<0.001). For MPV, a cutoff value of less than 8.5fl had a sensitivity of 92% and a specificity of 100% (
P< 0.001).
Conclusions: Higher disease activity in SLE is associated with a correspondingly low MPV.

Background: Amongst the different clinical and laboratory parameters used to monitor disease activity in systemic lupus erythematosus (SLE), mean platelet volume (MPV) is a novel biomarker. Although MPV has been studied in other rheumatological conditions like rheumatoid arthritis, its role in adult SLE needs to be defined, especially in Pakistan. Methods: The aim of this study was to evaluate the role of MPV as a biomarker of disease activity in SLE. Fifty patients were recruited through a consecutive non-probability sampling technique for this cross-sectional study. On the basis of their SLE disease activity index (SLEDAI) score of greater or lesser than 5, these 50 participants were divided into two equal groups respectively;25 patients with active SLE, and another 25 participants with stable, inactive lupus. MPV was measured in each group and compared using SPSS version 16. MPV was also correlated with SLEDAI and erythrocyte sedimentation rate (ESR). Independent sample t-test and Spearman's rho and Pearson's correlation tests were applied. Sensitivity and specificity of MPV were checked through ROC analysis. Results: The MPV of patients with active SLE (n=25, mean [M]=7.12, SD=1.01) was numerically lower than those in the inactive-SLE group (n=25, M= 10.12, SD=0.97), and this was statistically significant ( P<0.001). MPV had an inverse relationship with both ESR (r=-0.93, P<0.001) and SLEDAI (r s= -0.89, P<0.001). However, there was a strong positive correlation between ESR and SLEDAI (r s=0.90, P<0.001). For MPV, a cutoff value of less than 8.5fl had a sensitivity of 92% and a specificity of 100% ( P< 0.001). Conclusions: Higher disease activity in SLE is associated with a correspondingly low MPV.

Abstract
OBJECTIVE An increase in epicardial fat tissue (EFT) thickness was found to be associated with metabolic syndrome (MS) and ischemic heart disease. MS is a comorbidity of chronic obstructive pulmonary disease (COPD) resulting from the accompanying systemic inflammation. The aim of our study was to investigate the usefulness of EFT thickness to predict MS in COPD patients. METHODS COPD patients admitted to our clinic during January-December 2014 and healthy controls were included in this prospective case control study. Patients with comorbidities, COPD exacerbation, and malignancies were excluded. Patients and controls were compared in terms of anthropometric measurements, MS-related examination and laboratory findings, pulmonary function tests, and EFT thickness. The correlations between EFT thickness and markers of MS in COPD were evaluated using the Student's t-test and logistic regression analysis. RESULTS COPD patients and controls were composed of 82 and 84 individuals, respectively. MS was diagnosed in 31 (37.8%) COPD patients. The EFT thickness was significantly higher in COPD patients than in the controls and was also higher in COPD patients with MS than in those without MS (all p<0.001). Each 1-mm increment of EFT raised the risk of MS two-fold (p=0.011, OR=2.08, 95% CI: 1.18-3.68). Increase in triglyceride level (p=0.004, OR=1.02, 95% CI: 1.01-1.03) and reduction in forced vital capacity (p=0.025, OR=0.26, 95% CI: 0.08-0.84) were found to be associated with increased MS risk. The cut-off value for EFT thickness in the prediction of MS in COPD patients was 6.75 mm (sensitivity: 83%, specificity: 65%). CONCLUSION EFT thickness is a non-invasive and easily available parameter, which is valuable in the prediction of increased MS risk in COPD patients. Early diagnosis of patients at risk of MS may help to prevent ischemic heart disease in these patients.
