RESUMO
BACKGROUND: Erosive oral lichen planus (OLP) is, at times, extremely difficult to treat and has a major impact on patients' quality of life. There are only limited therapeutic options, such as topical and systemic glucocorticoids, retinoids, and immunosuppressants with considerable side effects and limited efficacy upon chronic use. OBJECTIVES: In the present individualised clinical trial, we assessed the efficacy of adjuvant intravenous immunoglobulins (IVIG; 2 g/kg/monthly cycle) in addition to the oral retinoid, acitretin, in three patients with refractory OLP over a period of two to six months. MATERIALS & METHODS: The efficacy of adjuvant IVIG treatment was evaluated using the Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) which measures both extent of mucosal lesions and functional sequelae. RESULTS: The three OLP patients showed mixed responses to adjuvant IVIG treatment, ranging from therapeutic efficacy to a lack of response to IVIG. CONCLUSIONS: In light of the observed therapeutic responses and a lack of good therapeutic options, adjuvant IVIG, although costly, warrants further investigation as a treatment option for OLP.
