Abstract
BACKGROUND
Oral candidiasis is a common opportunistic infection in patients with human immunodeficiency virus (HIV). In addition, most of these patients suffer from vitamin D deficiency. This study aimed to investigate the association between vitamin D levels and oral candidiasis in patients with HIV infection.
METHODS
This case‒control study was conducted on HIV-infected patients. Cases were patients with oral candidiasis diagnosed based on physical examinations. Controls were age- and sex-matched individuals without oral candidiasis. The levels of 25-OH vitamin D and other laboratory markers (CD4 count and viral load) were compared between the case and control groups.
RESULTS
A total of 104 cases and 102 controls were included in the study. The cases had significantly lower 25-OH vitamin D3 levels (MD = 33.86 ng/mL, 95% CI= (31.85, 35.87), P < 0.001) and CD4 counts (MD = 267.48 cells/mm3, 95% CI= (189.55, 345.41), P < 0.001) than the controls. In addition, viral load was significantly higher in cases than in controls (MD = 7.03 × 105 copies/mL, 95% CI= (4.46 × 105, 9.61 × 105), P < 0.001). The multivariate logistic regression analysis revealed that educational status (OR = 0.032, 95% CI= (0.002, 0.100), P < 0.001), current HAART (OR = 0.005, 95% CI= (0.001, 0.014), P < 0.001), history of oral candidiasis (OR = 20.114, 95% CI= (18.135, 21.957), P < 0.001), CD4 count (OR = 0.004, 95% CI= (0.001, 0.006), P < 0.001), viral load (OR = 12.181, 95% CI= (1.108, 133.392), P < 0.001), and vitamin D level (OR = 0.011, 95% CI= (0.008, 0.015), P < 0.001) were significantly associated with the risk of developing oral candidiasis.
CONCLUSIONS
Based on the findings, most patients with HIV infection suffer from vitamin D deficiency, especially those with oral candidiasis. Hypovitaminosis D was significantly associated with an increased risk of oral candidiasis. Thus, vitamin D supplementation may assist HIV-positive patients in improving their oral health and preventing oral candidiasis.
