Abstract
Clotrimazole, a commonly used antifungal agent, is employed in the treatment of otomycosis and other ear infections. However, its use can lead to adverse drug reactions (ADRs), occasionally manifesting as local irritation or allergic responses. This abstract presents a case study of a patient exhibiting an adverse reaction to clotrimazole ear drops, highlighting the clinical presentation, management, and resolution of the ADR. The patient, a 73-year-old male, presented with itching and erythema over the left pinna extending up to the middle of the sternum following clotrimazole ear drop application. Immediate cessation of the medication and symptomatic treatment led to rapid resolution of symptoms. This case emphasizes the importance of recognizing potential ADRs associated with clotrimazole ear drops and the necessity of prompt intervention to mitigate adverse effects, thereby ensuring optimal patient care.

Abstract
Fungal infections of the external auditory canal can range from common (otomycosis) to life threatening (necrotizing otitis externa). Proper identification of fungal pathogens is necessary to guide appropriate therapy, and a high index of suspicion for fungal causes of ear canal disease is critical. Fungal pathogens may be an especially important cause of ear canal disease in certain populations, including patients with diabetes, patients recently treated with antibiotics, and immunosuppressed patients. Opportunistic fungal infections of the ear canal are an emerging concern.

Curr Med Mycol 2023; 9:45-51. [PMID: 38375517 PMCID: PMC10874481 DOI: 10.18502/cmm.2023.345035.1402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 08/07/2023] [Accepted: 08/09/2023] [Indexed: 02/21/2024] Open
Abstract
Background and Purpose This review aimed to compare the efficacy of acidifying agents and clotrimazole in the treatment of patients with otomycosis. Materials and Methods The databases, including Research Gate, Google Scholar, ScienceDirect, Embase, Medline, Scopus, Cochrane, and library databases of clinical trials were searched in this study. The keywords were "Fungal Ear Infection" and "Otitis External" for otomycosis, "Clotrimazole", Lotrimin", "Mycelex", "Desenex", and "Clotrimaderm Mycoderm" for clotrimazole, and "Boric Acid Alcohol", "Alcohol-vinegar solution", Burow solution (Domeboro), "Isopropyl Alcohol", "VoSol" and "Acetic Acid" for acidifying agents. Regarding search strategy, a total of 53 studies were collected, 11 of which were maintained for assessment. Almost all studies were published after 1990. These articles discussed the role of clotrimazole and acidifying compounds in the treatment of otomycosis. Moreover, the route of administration, dosage, and side effects of these medications were highlighted. Results Eight studies had similar results and claimed that clotrimazole has the best or most significant effect on the treatment of otomycosis for patients suffering from pain, itching, swelling, and hearing loss. Conclusion Although all medications appear effective, there is a paucity of evidence to fully support the decision to choose between clotrimazole or acidifying agents for the treatment of otomycosis in terms of both efficacy and safety. However, in the biomedical field, the re-emerging investigation attention is due to the statements of a number of mechanisms defending the use of acidifying agents to treat mycosis (of antifungal-resistant species).

Isolation, Characterization, and Antifungal Sensitivity Pattern of Fungal Species with Potential Resistance to Antifungal Drugs in Patients with Otomycosis. ARCHIVES OF CLINICAL INFECTIOUS DISEASES 2022.

Abstract
Background: Otomycosis is defined as a superficial fungal infection, accounting for about 10% of infectious otitis externa cases. Objectives: This study investigated patients with suspicious symptoms through the examination of their demographic information, isolate etiological agents, and in vitro antifungal susceptibility patterns. Methods: The samples of 170 patients with otitis externa symptoms were collected and confirmed for otomycosis by mycological examination (e.g., potassium hydroxide, methylene blue staining, and fungal culture) and molecular sequencing. In vitro antifungal susceptibility tests against miconazole, fluconazole, itraconazole, voriconazole, posaconazole, amphotericin B, and caspofungin were performed according to the Clinical and Laboratory Standards Institute (M27-A3/S4 and M38-A2). Results: Out of 170 patients, 145 subjects (85.29%) showed positive mycological findings. In this study, 55.8% of the patients were male, and the most common age group affected was 50 - 59 years (26.2%). Hearing loss and pruritus were the most common clinical manifestations. The most common occupation was being a housewife (47.5%), and most cases occurred during the winter (40%). Aspergillus niger was the most common species, followed by Aspergillus fumigatus, Candida albicans, and Candida glabrata. Caspofungin showed the highest activity against Aspergillus and Candida isolates; nevertheless, itraconazole demonstrated the lowest activity against Aspergillus isolates. Fluconazole showed the weakest power against Candida species. Conclusions: Due to climatic conditions, humidity, and dust, otomycosis has a high occurrence in Iran. Although otomycosis needs long-term antifungal therapy and recurrence is high in some cases, it is rarely life-threatening, and eardrop antifungals are usually enough to eradicate the infection. Local information about the antifungal pattern is useful for the control, prevention, and treatment of otomycosis.

Abstract
PURPOSE Various agents with various antifungal properties are widely used for otomycosis eradication. However, there is still no consensus on the most effective agent. Therefore, the present study aims to investigate the efficacy of topical 1% isoconazole nitrate cream in the treatment of otomycosis. METHODS This prospective study included 43 patients who were applied to our outpatient clinic with complaints of ear pain, itching, aural fullness, and hypoacusis, and were diagnosed with unilateral otomycosis. After aspiration and cleaning, the external ear canal was filled with 1% isoconazole nitrate cream using an iv cannula and insulin syringe. Control examinations were performed on the 5th, 10th, 15th, and 20th days. In the follow-up examinations, patients were asked about how many days after the cream administration the pain and itching completely relief and the answers were recorded. RESULTS In the first control examination of 23 (92%) of 25 patients with pain, it was observed that the pain and otoendoscopic examination findings completely recovered. In the second control, it was found that both pain and otoendoscopic examination findings completely recovered in the remaining 2 patients (25 patients, 100%). 35 patients complained of itching and it was observed that itching and otoendoscopic examination findings completely recovered in 26 patients (75%) in the first control, 5 more patients (31 patients, 88.6%) in the second control, and 2 more patients (33 patients, 94.3%) in the third control examination. CONCLUSION Isoconazole nitrate cream appears to be an effective and easily applicable agent for the treatment of otomycosis.

Abstract
Fungal otitis externa, an infection of the external auditory canal caused by molds and yeasts, accounts for approximately 10-20% of ear canal infections accompanying high recurrence. The purpose of the current study was to assess the pattern of etiological agents of otomycosis and resistance profile as well as the rate of tympanic membrane perforation. A total of 1040 patients with symptoms of fungal otitis externa, in a period of two years, were investigated. The mycological tests revealed the presence of different fungi in 237 ears (22.8%). Fungal otitis was more related to filamentous fungi of the species Aspergillus flavus (54.43%), A. tubingensis (10.97%), and A. niger (8.86%), followed by yeasts, Candida orthopsilosis (7.59%), C. albicans (6.75%), and C. parapsilosis (5.06%). Tympanic membrane perforation rate was found to be 6.75% and was more common with otomycosis caused by A. flavus, A. tubingensis and C. albicans. In antifungal susceptibility tests, all tested drugs showed generally good activity against most isolates of molds and yeasts, while tolnaftate, clotrimazole, nystatin, and terbinafine had lowest effects. We found that among Aspergillus isolates, one A. niger isolate was resistant to voriconazole, and one A. flavus isolate was resistant to amphotericin B. Furthermore, among Candida species, three isolates of C. orthopsilosis showed high MIC values to fluconazole, two C. albicans isolates were considered fluconazole resistant and one isolate of C. parapsilosis was resistant to caspofungin and 3 isolates were resistant to fluconazole. Regarding the existence of the cases with perforated tympanic membrane and emerging species causing fungal otitis in the current report, the importance of the early physical examination, precise molecular identification, and the antifungal susceptibility evaluation is highlighted.

Abstract
This review sets out to highlighted knowledge gaps regarding the epidemiological, diagnostic (clinical and laboratory) and therapeutic aspects of otomycosis in Africa. A computerized literature search for otomycosis related articles were performed using MEDLINE. The search encompassed articles published in early January 1980 to May 2019 yielded 220 articles. Electronic search on PubMed was performed with the specific keywords. This review shows the higher prevalence rates of otomycosis in Africa. These prevalences varies from one country to the other and also from one population to another within the same country. The main symptoms are otalgia, otorrhea, hearing loss, aural fullness, pruritus, and tinnitus. Otomycosis is due to several predisposing factors, however, use of topical antibiotic/steroid eardrops, trauma to the external ear canal or instrumentation of the ear, being exposed to hot humid atmospheres, and close contact with water are the common risk factors. Aspergillus species are the most commonly identified organisms compared with Candida species. Worldwide, A. niger and C. albicans are the most commonly described agents of otomycosis in Africa. The Laboratory diagnosis of otomycosis is usually confirmed by mycologic tests relied on a set of evidences. Further conventional methods such as Chromagar Candida System, latex agglutination test, Biochemical tests (Api 20C AuxTM and auxanogram), phenotypical tests (Germ-tube and chlamydosporulation), and rRNA gene sequencing (PCR) are performed to improve diagnosis and the management of the disease. Adequate treatment of otomycosis includes microscopic suction clearance of fungal mass, discontinuation of topical antibiotics and treatment with antifungal eardrops for three weeks.

Abstract
OBJECTIVES/HYPOTHESIS To compare the efficacy and adverse effects of triamcinolone acetonide econazole cream and nystatin suspension in the treatment of otomycosis, and to determine the clinical features, predisposing factors, and etiology of otomycosis. STUDY DESIGN A prospective study. METHODS A prospective clinical trial was conducted on 786 patients diagnosed with otomycosis. The study population was randomly divided into two treatment groups of triamcinolone acetonide econazole cream (TAEC) and nystatin suspension in a 1:1 ratio. After clearing all fungal deposits in the external auditory canal, the antimycotic drugs were locally applied for at least 2 weeks. The efficacy and adverse effects were compared between the two antifungal reagents by statistical analysis. Meanwhile, patient clinical data were collected to find out the clinical features, predisposing factors, and etiology. RESULTS Pruritis was the most common symptom and Aspergillus niger was the leading fungal pathogen. There was high association (44.5%) of otomycosis with a history of unclean ear picking. The cure rate was 97.6% in the TAEC group and 73.5% in the nystatin group (P < .01). Treatment with TAEC resulted in 2.4% of patients complaining of discomforts (irritant dermatitis, otalgia, or headache) versus 59.8% of patients complaining discomforts treated with nystatin (P < .01). The residue rate of antifungals was 1.9% in the TAEC group and 89.9% in the nystatin group (P < .01) at the end of treatment. CONCLUSIONS Thoroughly cleaning of the external auditory canal followed by local use of TAEC under endotoscope is an effective, convenient, and well-tolerated treatment for otomycosis.

Abstract
BACKGROUND Refractory otomycosis is a common condition that is difficult to treat. OBJECTIVES This study aimed to evaluate the effectiveness of 1% topical voriconazole drops in the treatment of otomycosis. METHODS This retrospective analysis was conducted from November 2017 to November 2019. Patients who had refractory otomycosis without tympanic membrane perforation confirmed by microbial culture and fluorescent staining were included in the study. All patients were treated with 1% topical voriconazole drops hourly at daytime for 2 weeks. Evaluation of effectiveness was conducted 1 month after the completion of topical voriconazole treatment. Before and after topical voriconazole treatment, hearing tests were performed in all patients. RESULTS Fifty-five patients were included in this study. The reasons for refractoriness were resistant recurrence to imidazole drugs (50 cases, 90.9%) and difficulty in cleaning the external auditory canal (5 cases, 9.1%). The most common strain was Aspergillus terreus (50.9%), followed by Aspergillus flavus (29.1%), Aspergillus niger (10.9%), and Aspergillus fumigatus (9.1%). After 2 weeks of treatment with 1% topical voriconazole drops, otomycosis in all patients was resolved. There was no significant change in bone conduction before and after topical voriconazole treatment (paired t-test, P = 0.5023; linear correlation analysis, R2 = 0.98; equation, y = 1.003x-0.284). Adverse effects, such as blurred vision and phototoxicity, were not observed in any patient. CONCLUSIONS Administration of 1% topical voriconazole drops was effective and safe in the treatment of refractory otomycosis without tympanic membrane perforation within 2 weeks.

RESULTS (1) Oxymetazoline nasal spray applied at the time of surgery is equivalent to fluoroquinolone ear drops in the prevention of early postsurgical otorrhea and tympanostomy tube occlusion at the first postoperative visit. (2) Topical mupirocin 2% ointment is effective alone or in combination with culture-directed systemic therapy for the treatment of tympanostomy tube otorrhea caused by community-acquired, methicillin-resistant Staphylococcus aureus. (3) Topical clotrimazole 1% cream is highly active against the common yeast and fungi that cause otomycosis. A single application after microscopic debridement will cure fungal tympanostomy tube otorrhea in most cases. None of these 3 agents is ototoxic in animal histological or physiological studies, and each has proved safe in long-term clinical use. CONCLUSIONS Oxymetazoline nasal spray, mupirocin ointment, and clotrimazole cream are safe and effective as off-label medications for tympanostomy tube care in children.

Arisov MV, Indyuhova EN, Arisova GB. The use of multicomponent ear drops in the treatment of otitis of various etiologies in animals. J Adv Vet Anim Res 2020; 7:115-126. [PMID: 32219117 PMCID: PMC7096122 DOI: 10.5455/javar.2020.g400] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 12/18/2019] [Accepted: 12/20/2019] [Indexed: 02/01/2023] Open
Abstract
OBJECTIVE The objective of this study was to investigate the efficacy of newly developed multicomponent ear drops for the treatment of otitis caused by parasites, bacteria, and fungi in dogs, cats, ferrets, fancy rabbits, and foxes. MATERIALS AND METHODS A new drug for veterinary use was developed that contained levofloxacin hemihydrate (0.3%), clotrimazole (0.1%), dexamethasone sodium phosphate (0.1%), and moxidectin (0.01%). In the initial stage of otoacariasis (or the ear form of psoroptic scab), the drug was used twice with an interval of 5-7 days. When otoacariasis (psoroptic scab) was complicated by otitis of bacterial and/or fungal etiology, the drug was used as follows: instilled once a day, within 10-14 days in the ear canal for 2-5 drops of the drug. The study of therapeutic efficacy was performed on cats, dogs, ferrets, foxes, and fancy rabbits with ear pathology. RESULTS The recovery of cats, ferrets, dogs, and foxes after the double use of ear drops during otoacariasis was established. In the ear form of psoroptic scab in fancy rabbits after treatment, Psoroptes cuniculi mites were not detected. The specific (antimicrobial and antifungal) activity of the drug was confirmed in vivo using the following scheme of drug use: the drug was instilled once a day, within 10-14 days in the ear canal, 2-5 drops of the drug in animals with external otitis and otitis media. CONCLUSION The rational combination of active components developed in this study is effective and safe for use in animals with microbial diseases of the ears.

Role of Clotrimazole in Prevention of Recurrent Otomycosis. BIOMED RESEARCH INTERNATIONAL 2019; 2019:5269535. [PMID: 31950041 PMCID: PMC6944967 DOI: 10.1155/2019/5269535] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Accepted: 12/03/2019] [Indexed: 11/28/2022]
Abstract
Otomycosis is one of the relatively common diseases in the world which is caused by different fungi especially saprophytes. Concerning the relapse of this disease in a number of individuals, the present study was performed to evaluate the inhibitory effect of clotrimazole drop in the relapse of otomycosis. Clinical samples were taken by an ENT specialist from patients suspicious of having otomycosis. A part of these samples were stained, and others were cultured. The diagnosis of otomycosis was made on the basis of the recognizable and characteristic appearance of fungal hyphae or mycelium and fruiting bodies and/or conidiophores under microscopic examination. Patients with suspected otomycosis are not at risk of recurrence after treatment with clotrimazole drops. Out of the 161 individuals in whom definite diagnosis of otomycosis was made, the most affected individuals were, in the age range of 40–49 years, women, urban citizens, and housewives. Pruritus and diminished hearing were the main complaints of the patients. Aspergillus niger and A. flavus as well as Candida albicans were the main causes of the disease. The relapse of disease was observed in only five patients (3.1%), where A. niger was the main fungus. Most relapses were observed in women and in those with diminished hearing, manipulating the ears, ulcers in the canal, and tympanum. Our results suggested that usage of clotrimazole can be effective in reducing the relapse of otomycosis, and concerning the high cost of treating otomycosis while the low cost of using clotrimazole, usage of this drop is recommended to reduce the relapse of otomycosis.

Li Y, He L. Diagnosis and treatment of otomycosis in southern China. Mycoses 2019; 62:1064-1068. [PMID: 31368588 DOI: 10.1111/myc.12979] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 07/28/2019] [Accepted: 07/29/2019] [Indexed: 11/30/2022]
Abstract
To analyse and discuss the clinical features and pathogenic characteristics, diagnosis and treatment of patients with otomycosis in southern China. Two hundred fifty-six patients from southern China diagnosed with otomycosis were randomly separated into two groups: the drug filling group and drug smearing group. Patients in the drug filling group were first examined and then had the pathogenic secretions in their external auditory canals cleared by otoendoscopy. Then, the local antifungal cream triamcinolone acetonide clotrimazole was injected into the external auditory canal. The same treatment was undertaken 1 week later and repeated once or twice more. Patients in the drug smearing group were also treated by otoendoscopy. Then, they were told to smear their external auditory canals once per day with the antifungal cream. All cases were followed for more than 6 months after the 3- to 4-week treatment. The main symptoms and otoendoscopic examination were used to evaluate the prognosis. Aspergillus was the commonest fungus. The cure rate was 93% in the drug filling group and 81% in the drug smearing group. Otomycosis is very common in southern China, but it lacks characteristic features in its early stages. Once diagnosed, the local lesions in the external auditory canal should be cleared thoroughly using otoendoscopy, and then, the local antifungal cream is injected into external auditory canal. The cure rate can be significantly improved with the foregoing treatment.
