Systemic Diseases
Oral Manifestations of HIV/AIDS
The oral cavity is an early sentinel of HIV disease; classical lesions include pseudomembranous candidiasis, oral hairy leukoplakia, Kaposi sarcoma and necrotising periodontitis.
OHL cause
EBV
KS cause
HHV-8
Definitive Rx
ART
§ overviewOverview
Spectrum of opportunistic infections, neoplasms and idiopathic conditions of the oral cavity associated with HIV infection and immunosuppression.
§ epidemiologyEpidemiology
Occur in 30–80% of untreated HIV patients; reduced markedly by ART.
§ clinicalClinical Features
- 01Pseudomembranous or erythematous candidiasis, angular cheilitis
- 02Oral hairy leukoplakia (EBV) — corrugated white patch on lateral tongue, cannot be wiped off
- 03Kaposi sarcoma — HHV-8, purple palatal macules/nodules
- 04Non-Hodgkin lymphoma
- 05Linear gingival erythema, necrotising ulcerative gingivitis/periodontitis/stomatitis
- 06Aphthous-like ulcers (major)
- 07Salivary gland disease with xerostomia and parotid enlargement
- 08HPV-associated warts
§ investigationsInvestigations
- 01HIV serology and CD4 count
- 02Biopsy of persistent lesions (KS, NHL, OHL)
- 03Fungal smear/culture
§ classificationClassification
- 01EC-Clearinghouse: Group I strongly associated (candidiasis, OHL, KS, NHL, periodontal), Group II less commonly associated, Group III seen in HIV
§ treatmentTreatment
- 01Initiate/optimise antiretroviral therapy (mainstay)
- 02Candidiasis: topical nystatin/miconazole; systemic fluconazole for refractory
- 03OHL: aciclovir; recurs on stopping
- 04KS: ART ± intralesional vinblastine, radiotherapy, chemotherapy
- 05NUP: debridement + metronidazole + chlorhexidine + amoxicillin
- 06Standard universal infection control
§ complicationsComplications
- 01Systemic opportunistic infections
- 02Progression to AIDS
- 03Pain, dysphagia, weight loss
§ prognosisPrognosis
Excellent when ART maintains CD4 and viral suppression; lesions often regress.
§ examKey Examination Points
- 01OHL and NUP are highly suggestive of HIV — investigate
- 02Check CD4 before invasive procedures
§ revisionQuick Revision Summary
- 01Candidiasis · OHL · KS · NUP · ART is definitive treatment
