Brief Summary:
This study assesses the disinfectant and healing promoting effect of ozonated olive oil in treatment of pemphigus vulgaris and bullous pemphigoid in comparison to conventional topical treatment with topical antibiotic.

Condition or disease Intervention/treatment Phase
Pemphigus Vulgaris Bullous Pemphigoid Drug: Ozonated olive oil Drug: Topical garamycin cream Phase 3

Detailed Description:

All participants will be subjected to the following:

  • Written informed consent.
  • Detailed history and clinical examination and photographic documentation
  • Patients with pemphigus vulgaris (epidermal skin blisters) as well as those with bullous pemphigoid (subepidermal skin blisters) will receive systemic treatment, namely; pulse steroid therapy and either mycophenolate mofetil or azathioprine

    +/- monthly IV cyclophosphamide.

  • Two comparable contralateral lesions will be selected in every patient, which will be randomly assigned to either ozonated oil or conventional treatment.
  • Patients will apply ozonated oil to on one lesion followed by gauze compared to conventional topical gentamycin and potassium permanganate followed by gauze on the contralateral lesion. Role of topical treatment is essentially to prevent / treat secondary bacterial infection of skin erosions as well as promote wound healing by maintaining moist clean environment.
  • Surface area of both lesions will be calculated using digital planimetry, prior to starting treatment and by the end of treatment; namely end of the first cycle of intravenous pulse steroids on day 6 which defines end of intervention. Percent reduction on either side will be calculated.
  • For assessing disinfectant effect, swabs will be taken from the 2 selected lesions at the same intervals for assessing for bacterial as well as fungal growth.
  • Patients with positive cultures for bacterial growth will be given systemic antibiotics according to culture and sensitivity

Official Title: Ozonated Olive Oil in Treatment of Pemphigus Vulgaris and Bullous Pemphigoid Compared to Conventional Topical Treatment
Actual Study Start Date : November 1, 2022
Estimated Primary Completion Date : April 30, 2023
Estimated Study Completion Date : June 30, 2023

Arm Intervention/treatment
Experimental: Ozonated olive oil
ozonated oil will be applied to on one lesion followed by gauze for 5 consecutive days.
Drug: Ozonated olive oil
Topical treatment will be applied for 5 consecutive days on the erosions.

Active Comparator: Topical garamycin cream
conventional topical treatment will be applied to a comparable lesion followed by gauze for 5 consecutive days.
Drug: Topical garamycin cream
Conventional topical treatment will be applied for 5 consecutive days on a comparable erosion

Primary Outcome Measures :
  1. Healing promoting effect of ozonated olive oil [ Time Frame: 5 days per patient ]
    comparing percent change in surface area by digital planimetry in 2 selected comparable lesion

Secondary Outcome Measures :
  1. Disinfectant effect of ozonated olive oil [ Time Frame: 5 days per patient ]
    Comparing incidence of bacterial and fungal growth in the 2 arms
