NLR
Neutrophil-lymphocyte Ratio
The following variables were recorded: Complete Blood Count (CBC), Kidney Function Test (KFT) and Liver function Test (LFT), Absolute Lymphocyte Count (ALC), Absolute Neutrophil Count (ANC), Neutrophil-lymphocyte Ratio (NLR), Platelet Count (PLT), C-reactive Protein (CRP), Procalcitonin (PCT), serum ferritin, Lactate Dehydrogenase (LDH), fibrinogen, and Erythrocyte Sedimentation Rate (ESR) and ProBNP.
Pemeriksaan laboratorium yang sederhana seperti Neutrophil to Lymphocyte Ratio (NLR) dapat menggambarkan derajat keparahan pasien COVID-19 .
Background and Objectives: Neutrophil / lymphocyte (NLR) and thrombocyte / lymphocyte ratios (TLR) are also a guid- ing factors in the prognosticevaluation of infectious diseases.
Further studies and pathway analysis identified members of the NBD-LRR (NLR) family of pattern recognition receptors that regulate distinct mechanisms underlying overzealous inflammation.
Hemodynamic disturbance, a rise in neutrophil-to-lymphocyte ratio (NLR) and release of inflammatory cytokines into blood, is a bad prognostic indicator in severe COVID-19 and other diseases involving cytokine storm syndrome (CSS).
From the first hemogram of each patient performed after admission, the neutrophil-to-lymphocyte ratio (NLR), the derived NLR (d-NLR), the lymphocyte-to-monocyte ratio, the platelet-to-lymphocyte ratio, the neutrophil-to-platelet ratio (NPR), and the systemic immune-inflammation index (SII) were calculated.
Hence, we investigated the serum levels of vitamin D3 (cholecalciferol) and its metabolites (calcifediol and calcitriol), in addition to their relative ratios and correlations with angiotensin-converting enzyme 2 (ACE2), interleukin-6 (Il-6), and neutrophil–lymphocyte ratio (NLR) in COVID-19 patients compared with healthy controls.
Additionally, in sinusitis patients, the invasion was correlated with the neutrophil–lymphocyte ratio (NLR).
A high mean age (years), neutrophil count (%), neutrophil-to-lymphocyte ratio (NLR), ALT (U/L), procalcitonin (ng/mL), and hemoglobin (g/dL) level, and length of hospital stay (days), and a low lymphocyte count (%) and blood pH were associated with croup severity and need for intensive care.
Data on the patients’ demographic characteristics and laboratory tests, including platelet count (PLT), neutrophil count (NE), C-reactive protein (CRP), serum creatinine (SCR), and neutrophil-to-lymphocyte ratio (NLR), were collected.
Simple laboratory tests such as Neutrophil to Lymphocyte Ratio (NLR) can describe the severity of COVID-19 patients.
They were further allocated to the early elimination (EE) and prolonged elimination (PE) groups according to SARS-CoV-2 nucleic acid positivity duration.ResultsCompared to patients with EE, those with PE had increased serum concentrations of interleukin (IL)-5, IL-6, and IL-8; higher neutrophil count and neutrophil-to-lymphocyte ratio (NLR); lower lymphocyte, eosinophil, and red blood cell counts; and lower concentrations of hemoglobin and albumin (ALB).
Descriptive statistics and test performance measures were evaluated for monocyte percentage, MDW, white blood cell (WBC) count, and neutrophil to lymphocyte ratio (NLR).
A strong internal correlation was documented for both waves between outcomes and CBC-derived ratios, with the fourth-wave cases displaying lower admission values of the neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammation index (SII).
Aim of the study: To evaluate fasting plasma glucose (FPG) increase and neutrophil to lymphocyte ratio (NLR) as risk predictors of severe clinical outcome of COVID-19 pneumonia in type 2 diabetes mellitus (T2DM) hospitalised patients.
Risk factors for Hyponatremia were age 60 years (OR=2.52, p=0.006); DM (OR=2.79, p=0.001); Hypoxemia (OR=3.74, p0.001); Lymphopenia (OR=7.62, p0.009); Hypoalbuminemia (OR=9.15, p0.001); high serum Ferritin (OR=4.46, p0.001), high Neutrophil to Lymphocyte Ratio (NLR) (OR=3.58, p0.001) and AKI (OR=3.40, p0.001).
Prognostic values of novel markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and C-reactive protein to lymphocyte ratio (CLR) calculated from routine laboratory parameters have recently been reported to predict severe cases; however, whether this investigation can guide oxygen therapy in COVID-19 patients remains unclear.

The results also showed an increase in Neutrophil to Lymphocyte ratio (NLR) (31.4%), Platelet to lymphocyte ratio (PLR) (11.7%), Red Cell Distribution Width (RDW) (40.7%), D-Dimer  (73.4% ) dan High sensivity C-Reactive Protein (Hs-CRP)  (66.6%).
According to this urgency, a study was conducted on albumin levels, mean platelet volume (MPV), and neutrophil-lymphocyte ratio (NLR) as predictors of COVID-19 outcome.
