According to Ahsen et al, patients with FMF may benefit from using NLR as an acute phase response.16 Uluca et al discovered that patients in the attack-free phase had greater NLR levels, and they concluded that NLR may be a sign of the attack period in patients with FMF.17 NLR levels of juvenile FMF patients without symptoms and healthy controls were examined by Özer et al. They discovered that NLR and CRP exhibited a strong association, leading them to the conclusion that in patients with FMF, NLR may be a useful indicator of subclinical inflammation.18 Here, CRP is linked to familial Mediterranean fever.
