Non-Pharmacological Interventions to Prevent Oropharyngeal Candidiasis in Patients Using Inhaled Corticosteroids: A Narrative Review.

Inhaled corticosteroids (ICSs) are widely used to manage chronic respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and human immunodeficiency virus (HIV). However, prolonged use of ICS is associated with the development of oropharyngeal candidiasis, a fungal infection primarily caused by Candida albicans, due to local immunosuppression in the oral cavity. The incidence of oropharyngeal candidiasis varies depending on geographic region, patient age, and comorbidities, with immunocompromised individuals, those with diabetes, and the elderly being particularly vulnerable. Key risk factors include high ICS doses, poor oral hygiene, and improper use of inhalers. Prevention is the cornerstone of managing oropharyngeal candidiasis associated with the chronic use of inhaled corticosteroids. Patient education on proper inhaler technique and oral hygiene is essential to reduce the risk of fungal overgrowth in the oral cavity. Additional preventive strategies include the use of spacers, mouth rinsing after inhalation, and proper denture care. In cases where these measures fail to prevent the infection, prompt detection and early intervention are crucial to prevent progression or recurrence. This narrative review aims to analyze the most effective prophylactic measures to prevent oropharyngeal candidiasis associated with the chronic use of inhaled corticosteroids, emphasizing patient education, oral hygiene, and proper use of inhalation devices.
