Efficacy and safety of topical ciprofloxacin/dexamethasone versus neomycin/polymyxin B/ hydrocortisone for otitis externa

IntroductionAcute otitis externa (AOE) is a common but preventable ear condition. Tenderness with movement of the tragus or pinna is a classic feature of otitis Externa. Polymyxin B, neomycin, hydrocortisone preparations are the choice for first-line therapy when the tympanic membrane is intact. This study atiempted to compare the efficacy of polymyxin B, neomycin and polymyxin B, neomycin, hydrocortisone in the treatment of otitis Externa.ObjectiveTo compare the efficacy of polymyxin B, neomycin and polymyxin B, neomycin, hydrocortisone in the treatment of otitis Externa.MethodologyTo evaluate the efficacy of polymyxin B, neomycin and polymyxin B, neomycin, hydrocortisone in the treatment of otitis Externa, a hospital based, randomized, prospective study was conducted in Nepal Medical College and Teaching Hospital (NMCTH), Atiarkhel, Kathmandu from August 2012 to May 2014. 70 outpatients suffering from otitis Externa who met the inclusion and exclusion criteria were included. Patients were randomized into group A and group B with lotiery system. Odd number patients were included in group A and even number patients in group B. Group A patients received pack soaked with ribbon gauge in polymyxin B, neomycin ointment and Group B patients received pack soaked with ribbon gauge in polymyxin B, neomycin, hydrocortisone ointment. The patients were called for follow up after 48 hours and 96 hours to assess the improvement on the basis of tragal and circumduction tenderness either present or absent (present 1 or absent 2). A decrease in the clinical signs and symptoms (i.e. tragal and circumduc_on tenderness) was noted. Absence of pain was considered as clinically cured.ResultsIn comparison to polymyxin B, neomycin group, hydrocortisone group exhibited statistically significant effectiveness after 48 hours of treatment (p<0.05), but in cure rates after 96 hours, no statistical significant difference was observed between two groups (p>0.05).ConclusionPolymyxin B, neomycin, hydrocortisone group showed higher and faster cure rates than polymyxin B, neomycin group in the treatment of otitis Externa at 48 hours follow up.

Introduction Otitis Externa is common ear infection with a prevalence of 1%. Objective The objective of this study is to evaluate the clinical and microbiological efficacy and safety profile with oral ciprofloxacin in the external bacterial otitis (EBO) management. Methods This is a prospective observational study conducted with EBO outpatients referred to the otorhinolaryngology center in Moscow between March and August 2013. Our study included patients from two cohorts, acute external bacterial otitis (AEBO) - Group 1 - and exacerbation of chronic otitis externa (CEBO) - Group 2. We administered Ciprofloxacin 500 mg twice daily with standard topical EBO treatment for up to 10 days. Patients underwent evaluation on study visit days 1, 3, 5, and 10 for the severity. Bacteriological examination of ear canal cultures took place on Day 1 and Day 10. Results We collected data from 60 EBO outpatients (AEBO: N = 30 and CEBO: N = 30). Swimming was the major risk factor associated with the disease in addition to the most common pathogenic organisms - Staphylococcus aureus and Pseudomonas aeruginosa. was We attained complete resolution of the inflammatory process in 28 (93%) and 27 (90%) patients in the AEBO and CEBO group, respectively. We confirmed this by microbiological test with almost complete eradication of the causative organisms. Overall, we observed good positive dynamics of ear canal with no major side effects. Conclusion We found that Ciprofloxacin 500 mg, when administered orally twice daily for 7 to 10 days in otitis externa patients is clinically and microbiologically effective and comparatively safer than other antimicrobials.
