Abstract

Factors associated with hepatitis B virus (HBV) DNA breakthrough and the significance of YMDD variants without the presence of wild-type YMDD during prolonged lamivudine treatment are unknown. We studied the amino acid sequence of codon 552 (YMDD motif) and codon 528 by means of a line probe assay in 159 chronic HBV patients (median follow-up 29.6 months). Pretreatment HBV DNA levels and alanine transaminase (ALT) levels correlated inversely with the time to HBV DNA breakthrough with YMDD variants (r = −0.46, P = .001; r = −0.45, P = .001 respectively). Patients harboring YMDD variants 3 months before HBV DNA breakthroughs had higher HBV DNA breakthrough levels compared with those without YMDD variants 3 months before HBV DNA breakthroughs (18.9 × 10 6 vs. 5.4 × 10 6 copies/mL, P = .007). Patients with HBV DNA breakthroughs had higher percentages of YMDD variants without the presence of wild-type YMDD compared with patients without HBV DNA breakthrough (25.6% vs. 9%, P = .007 for single M552I variant; 20.9% vs. 8.1%, P = .026 for single M552V variant; 30.2% vs. 9.9%, P = .004 for M552I/M552V variants). Patients with HBV DNA levels of more than 10 3 copies/mL after 6 months of lamivudine therapy had a 63.2% chance of subsequently developing YMDD variants. HBeAg seroconversion occurred in 2 patients after the emergence of YMDD variants. Only one patient developed YMDD variant after HBeAg seroconversion. There was no increase in the rate of development of YMDD variants or L528M mutation in patients receiving lamivudine 25 mg daily or famciclovir 500 mg 3 times a day before being given lamivudine 100 mg daily.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
