Epidemiology and Relationships between CD4+ Counts and Oral Lesions among 50 Patients Infected with Human Immunodeficiency Virus

BACKGROUND: The aim of this study was to evaluate the clinical lesions of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome patients in the oral cavity, head and neck region and to determine their associations with level of immune suppression as measured by the CD4+ count. MATERIALS AND METHODS: In a descriptive cross-sectional study, 50 patients with a proven HIV infection were evaluated. Based on the clinical findings and CD4+ counts, the relationships between oral lesions and CD4+ cell count were investigated. RESULTS: The CD4+ count (cells/mm(3)) was <200, 200-500, and >500 in 32 cases (64%), 16 cases (32%) and 2 cases (4%) respectively, and the mean CD4+ count was 169.82 cells/mm(3) in males and 142.8 cells/mm(3) in females. All patients showed at least one oral manifestation. The most common oral lesion identified was pseudomembranous candidiasis accounting for 76% (38/50) followed by periodontal disease 34% (17/50), herpetic lesions and hairy leukoplakia 10% for each (5/50), gingivitis 8% (4/50), oral ulceration 8% (4/50), Kaposi’s sarcoma 6% (3/50), and Non-Hodgkin lymphoma 2% (1/50). CONCLUSION: The CD4+ count was decreasing the presence, and the severity of oral lesions was increasing in this study. The presence of oral lesions may lead to a positive diagnostic of HIV. Disease progression is characterized by increased prevalence of some oral lesions as candidiasis, hairy leukoplakia, and Kaposi sarcoma. The severity of oral lesions was more pronounced with a CD4+ count <200 cells/mm(3).
