The potential role of dyslipidemia in COVID-19 severity among Iraqi patients.

Background: The correlation between dyslipidemia and the severity of coronavirus disease 2019 has been widely categorized. Dyslipidemia is one of the most dominant disorders among these patients. Systemic inflammation accompanied by cytokine storm hemostasis modifications and severe vasculitis have all been reported to occur among COVID-19 patients, and these may contribute to some severe complications.

Objective: The aim of this study is to assess the possible relationship between dyslipidemia and the severity of coronavirus disease 2019.

Methods: This work encompassed 200 patients with coronavirus disease 2019 (100 dyslipidemic and 100 normolipidemic) who were hospitalized at Baghdad Teaching Hospital/ Medical City-Baghdad, Iraq, from October 2021 to October 2022; their ages ranged between 40 and 55. Eligible individuals had a positive nasal swab polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 infection. Every participant's anthropometric and clinical features were measured. The study includes the measurements of glycemic, lipid profile, renal function test, D-dimer, C-reactive protein, serum ferritin, and interleukin-6 in dyslipidemic and normolipidemic groups.

Results: Considerable increase (p= 0.001) in glycemic and lipid levels in the dyslipidemic group compared to normolipidemic. Moreover, dyslipidemic patients have higher lipid indices (ratios) than the normolipidemic group. Significant increases (p= 0.001) in serum urea and creatinine levels were found among the dyslipidemic group compared to normolipidemic. There was a non-considerable decrease (p= 0.062) in serum total protein in the dyslipidemic group concerning the normolipidemic. In contrast, a considerable decrease (p= 0.045) in serum albumin was detected in the dyslipidemic group compared to normolipidemic. D-dimer, serum C-reactive protein, ferritin, and interleukin-6 were significantly increased (p= 0.001) in the dyslipidemic group compared to normolipidemic.

Conclusion: Dyslipidemia potentially raises the severity of coronavirus disease 2019. There was a significant disturbance in renal function tests among coronavirus disease 2019 patients. The study found a significant and statistical difference in kidney functions between dyslipidemic and normolipidemic groups. The patients, especially the dyslipidemic ones, have experienced protein abnormalities and a significant inflammation rate reflected by higher C-reactive protein and interleukin-6, which is due to the severity of coronavirus disease 2019. It is possible to conduct more research with a larger sample size. The majority of people who have dyslipidemia need to be enlightened.
