About this study

Official title: Comparative Evaluation of Effect of Oral Zinc Supplementation and Placebo as an Adjuvant to Topical Corticosteroid Therapy in Oral Lichen Planus Patients

Lichen planus is an auto-immune, chronic inflammatory disease that affects mucosal and cutaneous tissue. Erosive and atrophic oral lichen planus (OLP) are difficult to manage because patients present with symptoms ranging from episodic pain to severe discomfort and they have the highest malignant transformation rate (MTR) amongst all the forms of OLP. Zinc is associated with regeneration of epithelium, wound healing and mediating T-lymphocyte function; all of which can lead to healing and re-epithelisation in the lesions of erosive OLP. Besides this, it also has anti-oxidant and anti-inflammatory properties, which lead to decrease in apoptosis and transformation into a malignant state.

This study intends to evaluate the effect of oral zinc supplements as an adjuvant to the topical corticosteroid therapy in the treatment of OLP.

Read the detailed description

Lichen planus is a chronic muco-cutaneous disorder of the stratified squamous epithelium that affects the oral and genital mucous membrane, skin, hair, nails and scalp.OLP is the mucosal counterpart of cutaneous lichen planus.The disease was first described by Erasmus Wilson in 1866. The prevelance of disease in the Indian sub-continent is about 2.6%,with the mean age being 30-60 years and with a female predilection. The cutaneous form is more persistent and resistant to treatment while OLP is more frequent in occurrence.

OLP is a potentially pre-malignant oral epithelial lesion. It is a T-cell mediated auto-immune disease in which the auto-cytotoxic CD8 + T cells trigger the apoptosis of the basal cells of oral epithelium.OLP is an idiopathic disease, although there are certain precipitating factors like HLA-A3, anxiety \& stress, diabetes and hypertension.

OLP occurs bilaterally, the most common sites being buccal mucosa, tongue, lips, gingiva, floor of mouth and palate. Wickham's striae are a pathogonomic feature. It has six clinical presentations- Reticular, Erosive, Atrophic, Plaque-like, Papular and Bullous.The reticular form is most common but its asymptomatic, while the erosive form is most severe with symptoms ranging from mild burning to severe pain. The range of MTR for OLP is about 0-5%, with the highest rate for erosive and atrophic types.Erosive OLP lesions arise as a complication of the atrophic process after trauma or ulceration. Appear as a central area of erosion with yellowish fibrinous exudate surrounded by erythema, with Wickham's striae in the periphery. Atrophic OLP lesions appear bright red due to loss of epithelium.

A review study done on the recent concepts in the treatment of OLP concluded that corticosteroids (mostly topical, rarely systemic) continue to be the mainstay of management of OLP. However, there are some other drugs which have a significant contribution such as- Calcineurin inhibitors (cyclosporine, tacrolimus, pimecrolimus), Retinoids, Dapsone, Hydroxychloroquine, Mycophenolate mofetil and Enoxaprin. The non-pharmacological treatment modalities include PUVA therapy, photodynamic therapy and laser therapy.

A recently conducted study found out that serum zinc levels were significantly decreased in patients with erosive OLP in comparison with patients of non-erosive OLP, which may be responsible for disintegration of epithelium in erosive OLP lesions.

The association of OLP and zinc lies in the fact that zinc is associated with the regeneration of epithelium, enhancement of enzyme activity, contributes to protein structure, helps in wound healing as well as inhibition and stimulation of lymphocyte reaction.The deficiency of zinc also leads to compromised T-cell mediated immune defence.Zinc also has anti-oxidant and anti-inflammatory properties, which can decrease apoptosis and transformation to a malignant state.

Thus, the present study intends to evaluate the role of oral zinc supplementation as an adjuvant to topical corticosteroid therapy on the treatment of oral lichen planus.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Oral Zinc supplementationDrug

    Also called Zinc Acetate

    In the test group, the patients will be administered Zinc Acetate tablets (equivalent to 30 mg of elemental zinc/day) for 6 weeks from the baseline. They will also be will be administered, topical corticosteroid paste- Triamcinolone acetonide- 0.1%, to be applied thrice a day till the lesions disappeared and the dosage will be tapered accordingly.The patients will be instructed to take the tablets and apply the paste after meals.The patients will be kept on a monthly follow-up for 3 months.

  • Oral placebo supplementationDrug

    Also called Placebo

    In the control group, the patients will be administered Placebo tablets for 6 weeks from the baseline. They will also be administered, topical corticosteroid paste- Triamcinolone acetonide- 0.1%, to be applied thrice a day till the lesions disappeared and the dosage will be tapered accordingly.The patients will be instructed to take the tablets and apply the paste after meals.The patients will be kept on a monthly follow-up for 3 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment of changes in size of the lesion

    Thongprasom score (TS) will be used to assess changes in the size of the lesion. Digital Vernier callipers will be used to measure the largest dimension of ulcers at baseline and at each follow-up visit.

    Measured: Baseline, 6 weeks and 3 months.

  2. Assessment of changes in pain and burning sensation of the lesion.

    Visual Analogue Scale (VAS) will be used to assess changes in pain and burning sensation of the lesion.

    Measured: Baseline, 6 weeks and 3 months

  3. Assessment of changes in changes in erythema and ulceration.

    Modified Oral Mucositis Index (MOMI)- will be used to assess changes in erythema and ulceration.

    Measured: Baseline, 6 weeks and 3 months

  4. Assessment of quality of life of the patient.

    Oral Health Impact Profile -14 index (OHIP-14) will be used to assess the quality of life of the patient.

    Measured: Baseline, 6 weeks and 3 months

Secondary outcomes (3)
  1. Number of episodes of new lesions in the follow-up period.

    The frequency of episodes of new lesions in the follow-up period will be assessed by visual examination

    Measured: Baseline, 6 weeks and 3 months

  2. Adverse effects of oral zinc supplementation.

    The will adverse effects of oral zinc supplementation.be assessed by interviewing the patients

    Measured: Baseline, 6 weeks and 3 months

  3. Requirement for additional systemic steroid therapy.

    The requirement for additional systemic steroid therapy will be decided by the presence of non-healing ulcers with persistent VAS scores

    Measured: Baseline, 6 weeks and 3 months
