BACKGROUND
Candida esophagitis (CE) is among the commonest esophageal infections and is known as an opportunistic fungal infection mostly affecting people living with the human immunodeficiency virus (HIV). However, some medical conditions might predispose HIV-negative individuals to esophageal candidiasis. The epidemiology and associated endoscopic findings of CE among people without HIV have rarely been reported.
AIM
To investigate the prevalence of CE among HIV-negative persons, and determine risk factors predicting CE.
METHODS
Between January 2015 and December 2018, all consecutive outpatients who underwent routine esophagogastroduodenoscopy as part of health check-ups at their own expense at the Health Check-up Center of the Kaohsiung Veterans General Hospital, Taiwan, were recruited in this study. Those with positive HIV serology results were excluded. Sociodemographic and clinical characteristics including age, gender, economic status, smoking history, alcohol consumption, tea and coffee consumption, underlying diseases, body fat percentage, body mass index, endoscopic findings, and Helicobacter pylori infection status were carefully reviewed. CE was confirmed by endoscopic biopsy and pathological assessment with hematoxylin and eosin and periodic acid-Schiff staining. To evaluate independent factors predicting the development of CE, we conducted a univariate analysis of clinical characteristics. The variables found to be significant via univariate analysis were subsequently included in a multivariable analysis of potential risk factors for CE development.
RESULTS
A total of 11802 participants were included in this study. Forty-seven (0.4%) were confirmed as having CE by pathological examination. Univariate analysis identified older age, the presence of chronic kidney disease, alcohol consumption, and steroid use (P = 0.023, < 0.001, 0.033, and 0.004, respectively) as significantly associated with CE. Multivariable analysis revealed older age [adjusted odds ratio (OR) = 1.027; 95%CI: 1.001-1.053; P = 0.045], chronic kidney disease (adjusted OR = 13.470; 95%CI: 4.574-39.673; P < 0.001), alcohol consumption (adjusted OR = 2.103; 95%CI: 1.151-3.844; P = 0.016), and steroid use (adjusted OR = 24.255; 95%CI: 5.343-110.115; P < 0.001) as independent risk factors for CE development. The presence of dysphagia was associated with severe CE (P = 0.021).
CONCLUSION
The prevalence of CE among HIV-negative persons was 0.4% in Taiwan. Independent risk factors for CE were older age, chronic kidney disease, alcohol consumption, and steroid use.
Core Tip: Candida esophagitis (CE) is not only an opportunistic fungal infection affecting people living with the human immunodeficiency virus (HIV) but has also been identified in HIV-negative individuals. The prevalence of CE in Taiwan has reached 0.4% in general population, higher than previous reports. Significant risk factors include older age, chronic kidney disease, alcohol consumption, and steroid use. It is among the etiologies causing dysphagia in the general population, and esophagogastroduodenoscopy combined with histopathological examination are essential for accurate diagnosis.
