The profile of hematinic deficiencies in patients with oral lichen planus: a case-control study

Abstract

Background: Oral lichen planus (OLP) is a relatively common mucocutaneous disorder, and its causative factors and pathogenesis are not fully understood. Existing studies on the association between hematinic deficiencies and OLP are limited and inconsistent. The aim of this study was to assess the hematinic deficiencies in a cohort of OLP patients and evaluate the correlation between hematinic deficiencies and OLP.Methods: A total of 236 OLP patients and 226 age-and-gender-matched healthy controls were enrolled in this study. The levels of hemoglobin (Hb), serum folate, vitamin B12 and ferritin were measured and compared between OLP patients and healthy controls. An REU (reticular/hyperkeratotic, erosive/erythematous, ulcerative) scoring system was adopted and compared between the OLP patients with and without hematinic deficiencies. The correlation between hematinic deficiencies and OLP was analyzed.Results: The frequencies of serum ferritin and vitamin B12 deficiency in OLP patients were both significantly higher than those of the healthy controls. According to gender and age, the profiles of hematinic deficiencies in OLP patients were significantly different. As for the REU score, no significant difference existed between OLP patients with and without hematinic deficiencies. Both serum ferritin deficiency and serum vitamin B12 deficiency were significantly correlated with OLP.Conclusions: The present study suggested a significant association between hematinic deficiencies and OLP. Iron, folate, and vitamin B12 levels in OLP patients should be monitored routinely. Further studies are warranted to explore the interactions between OLP and hematinic deficiencies.

Diagnostic Value of Oral “Beefy Red” Patch Combined with Fingertip Blood Mean Corpuscular Volume in Vitamin B12 Deficiency

“…Due to the rapid renewal, the oral mucosal cells are susceptible to the effects of DNA synthesis disorders related to VB12 de ciency, and oral damage predates neurological symptoms [9,10,11]. Recently, some studies reported signi cant VB12 de ciency among symptomatic oral lichen planus patients [12]. It is challenging for oral medicine specialists to make an early diagnosis for VB12 de ciency.…”
