OBJECTIVES
Adherence to the American Association for the Study of Liver Disease (AASLD) guidelines for the management of chronic hepatitis B (CHB) has not been systematically assessed. We sought to comprehensively evaluate adherence to five key areas of these guidelines. We also evaluated physician and patient factors underlying nonadherence, and predictors of nonadherence such as physician type, patient demographic factors, and phase of CHB infection.
METHODS
Nine hundred and sixty-two adult patients were retrospectively identified. Each patient chart was reviewed in detail. The primary outcome was adherence to five areas of the AASLD guidelines: (i) timely alanine aminotransferase (ALT)/hepatitis B virus DNA level checks needed to monitor inactive carrier and immune-tolerant phases; (ii) liver biopsy to guide decisions on initiating treatment; (iii) treatment initiation when indicated; (iv) hepatocellular carcinoma (HCC) screening; (v) testing for hepatitis A virus (HAV) immunity, HIV, and hepatitis C virus (HCV) co-infections.
RESULTS
Sixty percent did not undergo clinically indicated liver biopsies, largely owing to physician nonadherence. Eighty-nine percent of these missed biopsies were needed to further assess possible e-antigen-negative CHB. A high treatment initiation rate was found for the treatment eligible, but 121 patients had unclear treatment eligibility as they warranted, but did not undergo, liver biopsy. Forty-five percent did not have timely HCC screening, although gastroenterology physicians had the highest odds of adherence, and 29% did not have timely CHB lab assessment; patients seen by gastroenterologists had twice the odds compared with primary care physicians of undergoing timely lab monitoring. Thirty-five, 24, and 54% were not tested for HAV, HCV, and HIV co-infections.
CONCLUSIONS
Our findings show remarkably poor adherence to AASLD guidelines, particularly in the areas of liver biopsy, timely HCC and ALT monitoring, and testing for co-infection. These findings call for greater efforts to meet physician knowledge gaps, incorporation of decision support tools, and improved communication among providers.

BACKGROUND
In the Prevention of Malaria and HIV disease in Tororo pediatrics trial, HIV-infected Ugandan children randomized to receive lopinavir/ritonavir (LPV/r)-based antiretroviral therapy (ART) experienced a lower incidence of malaria compared with children receiving nonnucleoside reverse transcriptase inhibitor (NNRTI)-based ART. Here we present the results of the noninferiority analysis of virologic efficacy and comparison of immunologic outcomes.
METHODS
ART-naive or -experienced (HIV RNA <400 copies/mL) children aged 2 months to 6 years received either LPV/r or NNRTI-based ART. The proportion of children with virologic suppression (HIV RNA <400 copies/mL) at 48 weeks was compared using a prespecified noninferiority margin of -11% in per-protocol analysis. Time to virologic failure by 96 weeks, change in CD4 counts and percentages, and incidence of adverse event rates were also compared.
RESULTS
Of 185 children enrolled, 91 initiated LPV/r and 92 initiated NNRTI-based ART. At baseline, the median age was 3.1 years (range, 0.4-5.9), and 131 (71%) children were ART-naive. The proportion of children with virologic suppression at 48 weeks was 80% (67/84) in the LPV/r arm vs. 76% (59/78) in the NNRTI arm, a difference of 4% (95% confidence interval: -9% to +17%). Time to virologic failure, CD4 changes, and the incidence of Division of AIDS grade III/IV adverse events were similar between arms.
CONCLUSIONS
LPV/r-based ART was not associated with worse virologic efficacy, immunologic efficacy, or adverse event rates compared with NNRTI-based ART. Considering these results and the reduction in malaria incidence associated with LPV/r previously reported for this trial, wider use of LPV/r to treat HIV-infected African children in similar malaria-endemic settings could be considered.
