Efficacy of Pyodine Soaked Gelfoam vs Single Topical Application of Clotrimazole in Otomycosis Treatment

Otomycosis Clinical Trial

Official title: Efficacy of Pyodine Soaked Gelfoam vs Single Topical Application of Clotrimazole in Treatment of Otomycosis: a Randomized Controlled Clinical Trial

Status Completed

Clinical Trial Summary

Background and Objectives To compare the efficacy of gel foam-soaked pyodine with a single topical application of clotrimazole ointment. Subjects and Methods This randomized controlled trial will include 90 patients presenting to ENT OPD with complaints of earache, watery ear discharge, pruritis, and ear blockage and will be clinically diagnosed as a case of otomycosis on otoscopy. The external auditory canal of the patient will be cleared of fungal debris via suction before treatment In Group A ear canal will be filled with 1% clotrimazole ointment by using an IV catheter and syringe and in Group B pyodine-soaked gel foam will be placed in the external auditory canal. The patients will be followed up on post-treatment days 7 and 14.

Clinical Trial Description

INTRODUCTION: Otomycosis, external auditory canal fungal infection is a recurrent and prevalent condition affecting 9%to 27.2% of patients worldwide. Use of topical antibiotics, humid conditions, and trauma to the external auditory canal are well-recognized risk factors for this disease. Aspergillus nigar (60-90%), and Candida species (10-40%) are the most commonly isolated pathogens in patients with otomycosis. Otomycosis presents with bothersome symptoms such as pruritis, watery ear discharge, otalgia, and ear blockage which significantly impairs the patient's quality of life Therapeutic approaches for fungal ear infections include aural toilet, withholding topical antibiotics, starting topical antifungals, and enhancing patient well-being and cleanliness Multiple treatment options are available for the treatment of otomycosis but the recurrence rate of the disease is high. While several antifungal agents have been employed for its treatment, due to a lack of efficacy comparison it is difficult to select an appropriate option The choice of therapy plays an important role in achieving rapid symptom resolution and complete fungal eradication. Clotrimazole, a conventional antifungal agent, has been widely employed, but its efficacy is not always optimal. For topical treatment compliance of the patient and proper application of medication is also an important factor affecting the efficacy of the drug. Conversely, the utilization of pyodine-soaked Gelfoam is a novel approach that offers several advantages, including sustained drug release better drug penetration, and decreased risk of resistance as in the case of antifungals. Due to reduced compliance of the patients and ineffective technique of using topical antifungal otomycosis has a high rate of treatment failure and recurrence. Topical clotrimazole drops and povidine iodine solution have been compared for their efficacy in the past but a single topical application has not been compared until now. In this pursuit, we present a rigorous and comprehensive clinical trial designed to evaluate the comparative efficacy of two distinct treatment modalities: pyodine-soaked Gelfoam and a single topical application of 1% clotrimazole. The rationale behind this study is to address the escalating concerns regarding treatment-resistant otomycosis, as well as the need for cost-effective and practical solutions By addressing the question of which treatment is superior, this study endeavors to optimize the management of otomycosis, ensuring better patient outcomes and reduced healthcare costs. MATERIAL & METHODS: The main objective of this study is to evaluate the effectiveness of povidone iodine-soaked gel foam vs clotrimazole ointment in the management of otomycosis. A randomized controlled study was done in the ENT Department of Benazir Bhutto Hospital Rawalpindi over a period of 6 months from June 2023 to December 2023. Individuals with a clinical otomycosis diagnosis were recruited for the study. Individuals with active CSOM, external auditory canal abnormalities, and hearing aids were excluded from the study. A sample size of 90 patients was calculated. After approval from the ethical review board, patients were selected from the ENT clinic of Benazir Bhutto Hospital and enrolled in two treatment groups after obtaining informed consent. Complete history was taken from the patients and the ear canal was assessed by otoscopy. The aural toilet of all patients was done via suctioning of the ear canal. In Group A patient's ear canal was filled with 1% clotrimazole ointment by using an Intravenous catheter and syringe In Group B pyodine solution-soaked gel foam was placed in the external auditory canal. Followup of patients was done on the 7th and 14th post-treatment days otoscopy was performed and post-treatment symptom resolution and ear canal condition were assessed. Patients were allocated to three groups based on their clinical outcomes Good response Patients with a dry EAC and tympanic membrane intact Partial Response: Patients with scanty discharge but not completely dry EAC No Response: Patients with unusually high EAC Exudation ;
