Acute kidney injury (AKI) patients have increased bleeding risk, which could be partially due to acquired platelet dysfunction. We conducted a systematic review and a cohort study to investigate platelet function and count in AKI and their association with AKI-related bleeding and mortality. Through a systematic literature search in PubMed and Embase, we identified 9 studies reporting platelet function and 56 studies reporting platelet count or platelet indices in AKI patients. Overall, platelet aggregation was reduced in AKI patients in nonintensive care unit (ICU) settings but not in ICU settings, except that reduced aggregation was associated with renal replacement therapy...

Hospital-acquired acute kidney injury is a heterogeneous clinical syndrome that has multiple aetiologies, widely differing pathogeneses, variable clinical manifestations, and diverse outcomes. There is a persistent unmet need for novel biomarkers that offer timely diagnosis and accurate prediction of the short- and long-term sequelae of acute kidney injury (AKI). AKI is associated with systemic and intrarenal inflammation. The neutrophil-to-lymphocyte ratio (NLR), a readily available marker of inflammation and physiologic stress, has gained increasing attention as universal marker in AKI patients...

PURPOSE: We aimed to explore whether red blood cell distribution width (RDW) could serve as a biomarker to predict outcomes in critically ill patients with kidney failure in this study. MATERIALS AND METHODS: This retrospective study was conducted with the Medical Information Mart for Intensive Care IV (MIMIC-IV).A total of 674 patients were divided into three groups based on tertiles of RDW. We used the generalized additive model, Kaplan-Meier curve, and Cox proportional hazards models to evaluate the association between RDW and clinical outcomes...

INTRODUCTION: Plasmapheresis is a frequently used procedure that removes the pathogenic components from circulation. We aimed to evaluate the relationship between plasmapheresis, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and mortality in the intensive care unit (ICU) between 2014 and 2021. METHODS: 49 patients (27 females and 22 males) were included. Demographic characteristics, laboratory values of the day of admittance to the ICU, APACHE II scores, and length of stay were recorded...

BACKGROUND: Anemia is a common consequence of chronic kidney disease (CKD). Red cell distribution width (RDW) and mean corpuscular volume (MCV) are principally used for differential diagnosis of anemia. Limited evidence is available for its prognostic value for mortality in hemodialysis (HD) patients. We aimed to definite the relationship between RDW and MCV and mortality in HD patients. METHOD: This cohort study examined all-cause and cardiovascular (CV) mortality with 181 maintenance HD patients from February 2015...

Monocyte-to-lymphocyte ratio (MLR) and neutrophil-to-lymphocyte ratio (NLR) are considered as surrogate inflammatory indexes. Previous studies indicated that NLR was associated with the development of septic acute kidney injury (AKI). The objective of the present study was to explore the value of MLR and NLR in the occurrence of AKI in intensive care unit (ICU) patients. The clinical details of adult patients ( n  = 1500) who were admitted to the ICU from January 2016 to December 2019 were retrospectively examined...

Background: To address the problem of resource limitation, biomarkers having a potential for mortality prediction are urgently required. This study was designed to evaluate whether hemogram-derived ratios could predict in-hospital deaths in COVID-19 patients. Materials and Methods: This multicenter retrospective study included hospitalized COVID-19 patients from four COVID-19 dedicated hospitals in Sylhet, Bangladesh. Data on clinical characteristics, laboratory parameters, and survival outcomes were analyzed...

Platelet (PLT), one of blood cells, plays a major role in physiological and pathological processes such as coagulation, thrombosis, inflammation, and keeping the integrity of vascular endothelium. There are a group of parameters that are used to measure the total amount of PLTs, PLTs morphology, and proliferation. PLT indices are associated with the severity of illness and patients' prognosis. It was reported that mean platelet volume (MPV) was raising synchronously with interleukin (IL)-6 and C-reactive protein in sepsis, and was correlated to the severity of the disease...

BACKGROUND: Hypertension is the major public health concern; leading to cardiovascular disease. It is associated with alteration in hematological parameters which may lead to end-organ damage. Thus, this study aimed to compare hematological parameters between hypertensive and normotensive adult groups in Harar, eastern Ethiopia. METHODS: A comparative cross-sectional study was conducted from January to March, 2020 at Jugel and Hiwotfana Specialized University hospital, Harar, eastern Ethiopia...

BACKGROUND: Anemia and pancytopenia are not uncommon in patients with chronic kidney disease (CKD). Nevertheless, there is insufficient literature analyzing bone marrow pathology in patients with CKD or end-stage kidney disease (ESKD) receiving dialysis. METHODS: This observational cohort study included 22 patients with ESKD and 23 patients with CKD that received bone marrow biopsy and aspiration at Chang Gung Memorial Hospital. Demographic, hematological, and biochemical data were collected at the time of bone marrow study for analysis...

Objective This study evaluated the importance of bone marrow aspiration and trephine biopsy (BM) for the diagnosis of underlying hematological abnormalities in renal patients. Methods This cross-sectional study on BM was carried out between August 2010 and April 2019, in our specialist renal center for various unexplained hematological abnormalities in patients with renal diseases [chronic kidney disease (CKD), end-stage renal disease (ESRD) requiring maintenance hemodialysis (MHD), patients with normal renal function but other nephrology and urology issues like stone disease and nephrotic syndrome]...

BACKGROUND: Renal scarring is a significant complication in recurrent urinary tract infections in children that can lead to hypertension and end-stage renal disease. The present study evaluates whether platelet indices may be predictive for renal scarring. METHODS: Patients aged 1-18 years with recurrent urinary tract infections, whose medical records were reviewed to collect data on the presence of upper/lower UTIs and the results of scintigraphic investigations with 99m-technetium dimercaptosuccinic acid, were included in the study...

Patients with CKD display a significantly higher risk of cardiovascular and thromboembolic complications, with around half of patients with advanced CKD ultimately dying of cardiovascular disease. Paradoxically, these patients also have a higher risk of hemorrhages, greatly complicating patient therapy. Platelets are central to hemostasis, and altered platelet function resulting in either platelet hyper- or hyporeactivity may contribute to thrombotic or hemorrhagic complications. Different molecular changes have been identified that may underlie altered platelet activity and hemostasis in CKD...

INTRODUCTION: Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is a multisystemic disease. Despite the improvement in mortality rate since the introduction of immunosuppression, long-term prognosis is still uncertain not only because of the disease activity but also due to treatment associated adverse effects. The neutrophil-to-lymphocyte ratio (NLR) has been demonstrated as an inflammatory marker in multiple settings. In this study, we aimed to investigate the prognostic ability of the NLR in AAV patients...

Platelet-dependent mechanisms for excessive clotting and bleeding in CKD remain undefined. Moreover, the platelet's contributions to inflammation, and specifically to CKD, are equally elusive. To date, descriptions of changes in the functional properties of circulating platelets during CKD have provided confusing interpretations. Experimental approaches that can advance our understanding of platelet dysfunction in CKD are needed, and studies that provide mechanistic insights into the dynamic relationships between thrombosis, bleeding, and inflammation associated with CKD will be essential to improve clinical management and outcomes for this vulnerable population...

BACKGROUND: Patients with CKD are at high risk for thrombotic and hemorrhagic complications. Abnormalities in platelet function are central to these complications, but reports on platelet function in relation to CKD are conflicting, and vary from decreased platelet reactivity to normal or increased platelet responsiveness. The direct effects of uremic toxins on platelet function have been described, with variable findings. METHODS: To help clarify how CKD affects platelet function, we conducted a systematic review and meta-analysis of platelet activity in CKD, with a focus on nondialysis-induced effects...

OBJECTIVE: To systematically evaluate the predictive value of neutrophil-lymphocyte ratio (NLR) in acute kidney injury (AKI). METHODS: All studies about the predictive effect of NLR on AKI were searched in the National Medical Library of the United States PubMed Database, the Embase database in the Netherlands, the Chinese Biology Medicine disc (CBMdisc) and the Chinese Evidence Based Medicine Cochrane Centre Database (CEBM/CCD). The data updated by October 2020, and regardless of language, region or whether blind method was used...

Objectives: The association between platelet distribution width (PDW) and mortality in hemodialysis (HD) patients has received little attention. Methods: We retrospectively enrolled HD patients in a single center from January 1, 2008, to December 30, 2011. The primary and secondary endpoints were all-cause and cardiovascular mortality, respectively. The association between PDW and mortality was estimated by Cox regression model. Results: Of 496 patients, the mean age was 52...

INTRODUCTION: Mean Platelet Volume (MPV) has been revealed to be a risk factor for ischemic heart disease in the hemodialysis patients .The aim of present study is to investigate the association between MPV level with inflammatory and nutritional factors in patients requiring chronic hemodialysis. METHODS: 100 patients who were on maintenance hemodialysis were included. Based on the median MPV (8.7 fL) patients were divided into two groups of low and high MPV level to assess and compare in terms of inflammatory (erythrocyte sedimentation rate, C-reactive protein, and transferrin), and nutritional (albumin, ferritin, uric acid, blood urea nitrogen, creatinine, triglyceride, cholesterol, low density lipoprotein, and high density lipoprotein) parameters...
