Cytokine profile in multiple sclerosis patients with and without Covid-19.

Objective: Aim: To investigate the possible effect of COVID-19 disease on cytokine profile and some circulating growth factors in patients with multiple sclerosis (MS).

Patients And Methods: Materials and Methods: Serum cytokine levels as well as growth factors content were assessed be means of a solid phase enzyme linked‑immunosorbent assay in 97 MS patients of which 41 had and 56 did not have confirmed COVID-19 in the past 4-6-month period, and 30 healthy individuals who were age‑, and gender‑matched.

Results: Results: Some proinflammatory cytokine (such as TNFα, IFNγ) levels were higher while anti-inflammatory cytokine, namely IL‑4, was lower in MS patients compared to controls indicating Th1/Th2 imbalance.
