With the decline in renal function, patients with end-stage kidney disease (ESKD) can choose hemodialysis (HD), peritoneal dialysis (PD) or kidney transplantation as renal replacement therapy to improve their quality of life. Globally, HD is still the most important renal replacement therapy.\n\nWith the continuous development and optimization of dialysis technology, the survival time of maintenance hemodialysis (MHD) patients is gradually prolonged. However, even in developed countries, the mortality rate of MHD patients remains high. According to data from the United States Renal Data System (USRDS) in 2019, the MHD mortality rate in 2017 was 167 per 1,000 patient-years.\n\nStudies have shown that 30-50% of MHD patients have chronic inflammation state. Persistent inflammation can lead to a variety of complications, especially cardiovascular disease, malnutrition and anemia, thereby increasing the mortality of MHD patients.\n\nAlthough less than 5% of MHD patients die directly from inflammation, inflammation can interact with a variety of risk factors and has an important impact on the prognosis of MHD patients. Studies have found that inflammation is closely related to high-risk factors of death such as myocardial hypertrophy, ventricular dysfunction, atherosclerosis, protein energy consumption, anemia and renal bone disease .\n\nTherefore, the development of inflammation-related indicators has important clinical value for judging the prognosis of MHD patients and guiding early intervention.\n\nDisturbed functions of polymorphonuclear leukocytes \\[PMNLs\\] lead to an enhanced risk of bacterial infections and represent a main cause for the increased risk of morbidity and mortality among CKD patients.\n\nAfter chemotactic movement to the source of infection, PMNLs take up the invading microorganisms by phagocytosis and kill them with toxic oxygen radicals formed during the oxidative burst and proteolytic enzymes intracellularly released from granula.\n\nDisturbances of any of those crucial PMNL functions increase the risk for bacterial infections. The proneness of CKD patients to infections resulting from decreased phagocytosis is caused by factors such as uremic toxins, iron overload, anemia of renal disease, and dialyzer bioincompatibility.\n\nNeutrophils from HD patients show significantly elevated levels of reactive oxygen species (ROS) production, degranulation, and basal neutrophil extracellular trap (NET) formation, indicating spontaneous activation.\n\nFurthermore, similar to PMNLs from patients with acute infections. Monocytes are bone marrow derived cells that circulate in the blood for 1-3 days before differentiating into tissue macrophages or dendritic cells. In a review in this special issue, Girndt et al.\n\nfocuses on the differences of uremic monocytes in the expression of surface molecules, the production of cytokines and mediators, and in their function as compared to monocytes of healthy persons.\n\nBased on their CD14/CD16 expression profile, three distinct populations of monocytes can be distinguished: Mo1 ("classical monocytes" expressing CD14 only), Mo2 ("intermediate monocytes", CD14++/CD16+), and Mo3 ("non-classical monocytes", CD14+/CD16++). The Mo2 population has pronounced pro-inflammatory properties. Their proportion is an important predictor of mortality risk in HD patients \\[35\\].\n\nThe contribution of monocytes to the dysregulated immune response in uremia can be based on altered features of the individual cells or on a change in the relative numbers of the three different populations. Monocytes play an important role in both innate immunity and antigen presentation for specific cellular immune defense.\n\nIn patients with chronic renal failure as well as those treated with maintenance hemodialysis, these cells are largely dysregulated.\n\nMonocytes and macrophages strongly contribute to the pathogenesis of atherosclerosis. These cells invade the vessel wall at sites of endothelial lesions and participate in the formation of foam cells, the deposition of lipids in the intima, and the growth of the atheromatous plaque. Macrophages within vascular plaques express inflammatory markers .\n\nThese observations prompted the study of a relationship between the activation of circulating monocytes in the blood of dialysis patients and their risk of atherosclerotic vascular disease. Investigators found many hints that such relation exists. Studies in dialysis patients described correlations between monocyte expression of IL-1 and IL-1RA and cardiovascular events.\n\nThe relative frequency of CD14++/16+ Mo2 cells relates to this morbidity in different cohorts with CKD including HD, PD and CKD patients stages 1-5 \\[37,35,33\\].\n\nA high expression of ACE on monocytes appears to be associated with cardiovascular disease in HD and PD patients.\n\nIn addition, the intensity of monocyte sequestration during a dialysis session as a surrogate for the activation level of this cell type is predictive for cardiovascular events as well.\n\nSince many of the morphological and functional alterations of monocytes are found in both CKD 3-5 and dialysis patients, uremic toxicity may be one of the important causal factors.\n\nHowever, hemodialysis accentuates some of the monocyte abnormalities. This might be the consequence of inflammatory activation through blood-membrane interactions, and biocompatibility issues may play a role.\n\nFurther, dialysis can clear several but not all retention solutes from the blood of uremic patients. It is thus reasonable to test different dialysis modalities (HDF, high cut-off dialysis) if they influence monocyte dysfunction. All these aspects have been addressed in clinical or experimental studies.\n\nRecent studies have found that the ratios of different blood cell components are new inflammatory markers, which have good predictive value in the outcome of CKD, cardiovascular disease, rheumatic disease, etc., including neutrophil-to-lymphocyte ratio (NLR) , monocyte-to-lymphocyte ratio (MLR) , Previous studies have inconsistent conclusions about the predictive value of NLR and MLR on mortality of HD patients. Xiang et al. suggested that higher MLR was a strong and independent predictor of all-cause and cardiovascular mortality and overwhelmed NLR among HD patients .\n\nThis study hypothesized that the combination of NLR and MLR could form a new indicator for predicting the mortality of HD patients. Therefore, the study incorporated NLR and MLR into an inflammation scoring system and investigated the value of inflammation score in predicting all-cause and cardiovascular mortality in HD patients.\n\nBesides neutrophil and lymphocytes, monocytes play a key role in inflammation and are well known as a central factor in pathogenesis of atherosclerosis. Patients with ESRD exhibit a general expansion of circulating monocytes with increased basal production of cytokines and reactive oxygen species (ROS), which contribute to the prevailing oxidative stress and systemic inflammation in this population. On the other hand, this kind of spontaneous activation is accompanied by decreased phagocytic capacity of monocytes and impaired antigen presentation capacity, thus leading to defective functions of T and B cells; the impaired expression of co-stimulatory molecules also contributes to this phenomenon. Findings from epidemiological studies indicate that elevated monocyte counts are independently related to all-cause and cardiovascular mortality in HD patients.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'healthy persons as control group patients with chronic kidney disease (CKD) stage 4-5 (not on dialysis) patients ESRD on maintenance hemodialysis', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* \\- Hemodialysis patients \\> 18 years\n* \\< 60 years old\n* CKD stage (4-5) not on dialysis\n\nExclusion Criteria:\n\n* o Recent acute coronary or cerebrovascular accident\n\n * Autoimmune diseases\n * Hematological diseases\n * Liver cirrhosis\n * Active or pre-active infection\n * Malignancy\n * Medications as Aspirin, NSAI, immunosuppressive steroid.'}, 'identificationModule': {'nctId': 'NCT05887960', 'briefTitle': 'Impact of Neutrophil Lymphocyte and Monocyte Lymphocyte Ratio on Chronic Kidney Disease Patients Outcome', 'organization': {'class': 'OTHER', 'fullName': 'Assiut University'}, 'officialTitle': 'Impact of Neutrophil Lymphocyte and Monocyte Lymphocyte Ratio on Chronic Kidney Disease Patients Outcome', 'orgStudyIdInfo': {'id': 'CKD patients'}}, 'armsInterventionsModule': {'armGroups': [{'label': '1', 'description': 'healthy persons to see normal ratio of of neutrophil lymphocyte and monocyte lymphocyte', 'interventionNames': ['Other: CBC and flow cytometry test for monocyte']}, {'label': '2', 'description': 'CKD patients stage (4-5) not on dialysis to see impact of (NLR) and (MLR) as regard inflamation and cardiovascular complications', 'interventionNames': ['Other: CBC and flow cytometry test for monocyte']}, {'label': '3', 'description': 'patients ESRD on maintenance hemodialysis compared with CKD pre dialysis patents and see if hemodialysis is better for removal toxic granules and inflamatory markers caused by CKD', 'interventionNames': ['Other: CBC and flow cytometry test for monocyte']}], 'interventions': [{'name': 'CBC and flow cytometry test for monocyte', 'type': 'OTHER', 'description': 'all groups assigned Cbc with leukocyte differential and flow cytometry for monocyte population', 'armGroupLabels': ['1', '2', '3']}]}, 'contactsLocationsModule': {'centralContacts': [{'name': 'Abdelrahman HA Mohamed, specialist', 'role': 'CONTACT', 'email': 'drabdelrahmanmohyeldein@gmail.com', 'phone': '201009749401'}, {'name': 'Samir KM Abdelhamid, professor', 'role': 'CONTACT', 'phone': '201117462007'}], 'overallOfficials': [{'name': 'Ashraf AN el shazly, profeassor', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Assiut University'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Assiut University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Impact of neutrophil lymphocyte and monocyte lymphocyte ratio on chronic kidney disease patients outcome', 'investigatorFullName': 'Abdel rahman Hassan Mohamed', 'investigatorAffiliation': 'Assiut University'}}}}
