Liver International, 41(2), 295-299.1478-32231478-3231https://onlinelibrary.wiley.com/doi/10.1111/liv.14740https://hdl.handle.net/11452/40013The role of low levels of HDV-RNA during and after interferon therapy of hepatitis D is unknown. We re-analysed HDV RNA in 372 samples collected in the HIDIT-2 trial (Wedemeyer et al, Lancet Infectious Diseases 2019) with the Robogene assay (RA; Jena Analytics). Data were compared with the previously reported in-house assay (IA). We detected HDV-RNA in one-third of samples previously classified as undetectable using the highly sensitive RA. Low HDV viraemia detectable at week 48 or week 96 was associated with a high risk for post-treatment relapse, defined as HDV RNA positivity in both assays at week 120. HDV RNA relapses occurred in 10/15 (67%) patients with detectable low HDV RNA at week 48 and in 10/13 (77%) patients with low viraemia samples at week 96. In contrast, the post-treatment relapse rate was lower in patients with undetectable HDV RNA in both assays during treatment.eninfo:eu-repo/semantics/closedAccessHDVHepatitis DPCRRelapseResidual viraemiaVirus-RNAQuantificationGastroenterology & hepatologyArticle0005957143000012-s2.0-8509708576329529941233217778https://doi.org/10.1111/liv.14740Gastroenterology & hepatologyHepatitis Delta Virus; Chronic Hepatitis D; Hepatitis BAlanine aminotransferaseAspartate aminotransferasePeginterferon alpha2aTenofovir disoproxilVirus RNAAntiviral therapyArticleCombination drug therapyControlled studyDisease associationFollow upHepatitis DHumanInfection riskLimit of detectionMajor clinical studyNull resultPredictive valueRecurrence riskRNA analysisViremiaVirus load
