Abstract

COVID-19 (Corona Virus Disease 2019) was a life-changing pandemic with impact on social, environmental, health, and economic issues. Various inflammatory and hematological biomarkers studied individually or in combination in the literature have shown significant results with regard to COVID-19 pathology, severity, and prognosis. Yet the question of interest is how covid-19 inflammatory cascade impacts the interlink between the biomarkers during different stages. This study aims to retrospectively analyse ferritin, albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, direct bilirubin, blood urea nitrogen (BUN), creatinine, D-dimer, Lactate Dehydrogenase (LDH), C Reactive Protein (CRP) and Interleukin-6 (IL-6) levels between two groups based on COVID-19 severity.  A retrospective cross-sectional study was conducted with laboratory data of COVID-19 patients admitted at Sri Ramachandra Medical College Hospital, India. The sample size was 104 [Group1: severe disease, n=52; Group-2: mild disease, n=52]. After normality testing, data were compared between the two groups followed by correlation analysis between the variables. A p<0.05 was considered statistically significant. On comparison, Group 2 (severe COVID-19 disease) showed significant difference in the levels of all the biomarkers (p<0.005) except Creatinine (p<0.128) when compared with Group 1 (mild COVID-19 disease). Significant correlation was obtained between all biomarkers (p<0.005) except creatinine. The correlation analysis primarily explains the inflammatory cascade involved in disease. Ferritin appears to have a standalone effect on disease severity, progression, organ dysfunction. This understanding can be used to provide better and more timely care.

Abstract

The objective of this study is to analyse the levels of Thyroid stimulating hormone (TSH) and the Bone Mineral Profile (Vitamin D, Parathyroid hormone (PTH), calcium, phosphorus, magnesium, and alkaline phosphatase [ALP]) levels in the early stages of chronic kidney disease (CKD) based on Glomerular filtration rate (GFR). A retrospective analysis was conducted involving 247 CKD patients admitted to the nephrology department at Sri Ramachandra Medical College Hospital from January to June 2022. The estimated GFR (eGFR) was calculated utilizing the CKD-EPI formula provided by the National Kidney Foundation. All biomarkers were analysed using automated platforms. The baseline ages for the three groups were 52.5, 68, and 66.5 years respectively (p<0.001). The comparative analysis revealed statistically significant differences solely among Vitamin D, creatinine, PTH, and phosphorus across the three groups. Further correlation analysis demonstrated changes in bore significant correlations with only creatinine, vitamin D, and PTH. This study concludes that in the early stages of CKD, vitamin D followed by PTH appears to be the earliest biomarker for assessing CKD-Mineral and Bone Disorder (CKD-MBD) occurring prior to any alterations in calcium and phosphate levels. As such, early consideration of supplementation may prove beneficial in mitigating disease progression and preventing cardiovascular complications.
