Prevalence of oral candidiasis in asthma and COPD patients using inhaled corticosteroids in the Philippine General Hospital Department of out-patient services

Background and Objectives@#Oral candidiasis (OC) is a well-known local side effect of inhaled corticosteroid (ICS) therapy in patients with asthma and chronic obstructive pulmonary disease (COPD). This study aimed to determine the prevalence of OC and its association with ICS-related factors in out-patient asthma and COPD patients of the Departments of Pulmonology and Pediatric Pulmonology of the Philippine General Hospital (PGH).@*Methods@#This is a cross-sectional study conducted from October 2019 to January 2020. Data was collected through a two-part questionnaire accomplished by doctors and patients with asthma or COPD. Results. A total of 67 patients were included in the study. Oral candidiasis was observed in 4 (5.97%) ICS users, and the prevalence was 1.65% to 14.59% (95% CI, SE: 0.028946).@*Conclusion@#This study determined the prevalence of oral candidiasis in asthma and COPD patients and its association with ICS-related factors, including the dosage, medication, device, and duration of therapy. The prevalence of OC in ICS users in PGH cannot be interpreted as high or low due to the small number of respondents, but is consistent with OC prevalence found in related literature. Increased prevalence was observed in adult females with asthma under low dose ICS therapy with Fluticasone/Salmeterol DPI for more than a year. There was no statistically significant correlation among OC prevalence, age, sex, and components of ICS-therapy including dosage, medication, device, frequency, and duration of therapy. A large-scale study is recommended for more accurate assessment of OC prevalence in the population and to determine statistically significant associations among the factors. It is also recommended to quantifiably measure patient compliance, inhalation technique and instruction, and its association to OC prevalence. Findings may be used to strengthen patient education, preventive measures, and disease management to facilitate improved compliance and effective treatment outcomes.
