OBJECTIVE
This study aimed to detect and quantify the HIV-1 viral load in ranula fluid of HIV-positive patients.
STUDY DESIGN
Fourteen HIV-positive patients (13 not on highly active antiretroviral therapy) presenting with ranulas were prospectively evaluated. The viral load in the ranula fluid was quantified, and the results were correlated with CD4(+) cell count and viral load in the patient's blood. The NucliSens EasyQ system (NucliSens Easymag; bioMérieux), which is based on nucleic acid sequence-based amplification and real-time detection using molecular beacons, was used to quantitate viral RNA in the fluid.
RESULTS
Concentrations of HIV-1 RNA ranged from 25 to 1,600,000 copies/mL in the fluid. However, no significant statistical correlation could be established with either CD4(+) cell count or viral load in patients' blood.
CONCLUSIONS
Various concentrations of HIV-1 RNA were found in ranula fluid, which appears to serve as a viral reservoir in HIV-infected patients.
