Does viral load reduction improve activation and function of natural killer cells in patients with chronic hepatitis B?
The specific defect in CD56(dim) NK cell activation and the reduced capacity to produce anti-viral and Th1-skewing cytokines may play a role in HBV persistence. Restoration of this NK cell cytokine-producing capacity, as achieved by viral load reduction, could therefore contribute to definite clearance of the virus.
In treating patients with IPN, a primary conservative strategy resulted in mortality that was comparable with that after surgery, and 76% of the patients were able to avoid surgery; 54.5% of IPN patients were successfully managed with the primary conservative strategy.
