- Abstract
Complete blood count derived inflammation biomarkers such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), neutrophil/platelet ratio (NPR) and systemic immune inflammation index (SII) have already been investigated as predictors of prognosis of systemic inflammatory, cardiovascular, malignant diseases, etc., and with the imminent SARS-CoV-2 pandemic, they also began to be studied as biomarkers of interest in this disease. Objective: To retrospectively compare the value of these 4 hematimetric ratios during the two years of the pandemic (2020-2021), with the previous period (2018-2019), in a population of kidney disease patients undergoing hemodialysis. Methods: This research was submitted to the Ethics and Research Committee of the State University of Ponta Grossa (CEP-UEPG) and was approved under protocol number 5.024.864. Patients treated in the Renal Replacement Therapy sector of Hospital Santa Casa de Ponta Grossa during the years 2018 – 2021 were included, with a sample size of 155 patients. Data collection was based on consultation of electronic medical records. The value of the NLR, NPR, PLR and SII ratios were calculated from the count of neutrophils, lymphocytes and platelets in the blood counts, considering one blood count every quarter in this 4-year interval. As the normality of the data was not attested, the non-parametric methodology was followed, the value of α was set at 0.05. Results: The Skillings-Mack test showed a significant simulated p-value (< 2.2e-16) when comparing each of the four ratios. In the post-hoc analysis, the quarterly comparisons of the SII medians did not show a significant difference, the PLR, NPR and NLR ratios showed two, three and six comparisons with significant differences, respectively. Conclusion: There were comparisons with significant specific differences, there was no general increase in the value of the SII, PLR, NPR and NLR ratios during the pandemic period (2020 - 2021) among hemodialysis patients.
