Do decreasing levels of HBsAg predict HBsAg seroclearance in patients with inactive chronic hepatitis B virus infection?
The decrease in the level of HBsAg accelerates during the 3 years before HBsAg seroclearance. Levels of HBsAg of 200 IU/mL or less have high NPVs for HBsAg seroclearance; PPVs increase to 97% to 100% when combined with a 1 log IU/mL or more decrease in level of HBsAg over a 2-year period.
Combined spine and SIJ MRI added little incremental value compared with SIJ MRI alone for diagnosing patients with nr-axSpA and enhancing confidence in this diagnosis.
