Abstract
Introduction: The effect of isotretinoin on inflammatory markers has been reported with conflicting results. No studies have been reported on the relationship between isotretinoin and lymphocyte/high-density lipoprotein cholesterol [HDL-C] ratio (LHR), neutrophil/HDL-C ratio (NHR), or platelet/HDL-C ratio (PHR) in acne patients.
Objectives: We aimed to investigate how isotretinoin affects the inflammatory markers, including LHR, NHR, and PHR, in acne vulgaris patients.
Methods: A total of 361 patients with moderate-to-severe acne vulgaris who received systemic isotretinoin for at least six months were included. Complete blood count and biochemical analyses, including monocyte/HDL-C ratio (MHR), NHR, LHR, PHR, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), platelet/lymphocyte ratio (PLR), the aggregate index of systemic inflammation (AISI), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI), obtained at the treatment onset and the end of the first, third, and sixth months of treatment were investigated.
Results: There was no significant difference in MHR and NHR levels between repeated measures. A significant increasing trend was seen in LHR and PHR (P = 0.001 and P = 0.011, respectively). HDL-C levels gradually and significantly declined during the six months (P < 0.001). Serum NLR, derived NLR, SII, SIRI, MLR, and AISI showed a significant decrease in line with clinical improvement in acne during the six months of therapy (P < 0.05).
Conclusions: Declining levels of NLR, MLR, SII, SIRI, and AISI may indicate the anti-inflammatory effects of isotretinoin on the pilosebaceous unit, whereas increasing levels of LHR and PHR may show systemic inflammatory activity of isotretinoin.
